摘要:
The conveying system uses a movable trolley containing vertically spaced support surfaces, each of which has parallel tracks for receiving peg trays. The trolley is movable onto a transferring conveyor, for example, at the end of a ring spinning machine. The transfer station has conveyors for conveying rows of peg trays onto and from the trolley.

The device for brewing beverages includes a brewing receptacle (1) and an associated brewing sieve (2) in the form of a porous holder (2) for the material requiring brewing (7). It has mechanical-hydraulic device for automatically and adjustably ending the brewing process. This device includes a holder (2), which has a lighter specific weight than water, and can be introduced into brewing receptacle (1), as well as a weighing-down element (11), by way of which holder (2) for the material requiring brewing (7) can be kept submerged in the brewing liquid (9) in the brewing receptacle (1) for a pre-set length of time. The weighing-down element (11) includes of an upwardly open container (28) filled with water, which rests on holder (2) and has an opening (29) at the bottom through which the water (30) in the weighing-down element can flow into insert ring (3). As soon as container (28), and hence holder (2) as well, is relieved of the weight of the water in container (28), holder (2) begins to rise up and lifts the material requiring brewing (7) out of brewing liquid (9).

A process for the transportation of cans between machines processing fiber slivers by means of a can conveying device. The latter is loaded and unloaded simultaneously in one position at a machine or storage facility. The cans are inspected during their transportation between two such machines. In this process, the cans in which fiber sliver remnants remain, are emptied. The route of the can conveying device constitutes a transportation system consisting of three interconnected can circuits, whereby a first can circuit comprises two such machines and the other two can circuits each comprise one of these machines and the can storage facility. The can shifting device, to load and unload the can conveying device is equipped with a grasping device to grasp the can and with a lifting device to lift up the grasped can. The gasping device is located on a sled that can be shifted perpendicularly to the longitudinal extension of the can conveying device which is, in turn, located on a supporting sled capable of moving at a perpendicular to the longitudinal extension of the can conveying device.

An endless conveyor for ring spinning machines comprises bobbin pegs (13) for receiving full and/or empty bobbins which seen in the conveying direction of the endless conveyor (17) must assume an exact position on the endless conveyor (17) in order in a predetermined bobbin change position to come into alignment with a spinning point (11) or other bobbin support arrangement and thus ensure a perfect bobbin transfer from or to the bobbin peg (13). Each bobbin peg (13) is mounted on the endless conveyor (17) adjustably in the conveying direction via a driver (19).
摘要:
The carriers which carry the roving bobbins are moved from the conveyors which are parallel to the spinning machine on branches which extend laterally into the spinning machine to effect a bobbin changeover of transverse rows of bobbins in the machine. The branches extend angularly, for example, at angles of 45.degree. to 90.degree. to the center plane of the spinning machine and may extend to near the center plane or across the width of the machine.
摘要:
A dosing apparatus for small doses of a substance, particularly for types of pharmaceutical substances, includes a shoulder and a nozzle for use as a dropper or sprayer on the shoulder. Two outer arms are connected to the shoulder and a container, preferably formed as a hollow cylinder, is located between the two outer arms. An inner arm is formed at an acute angle to each adjacent outer arm with the two outer arms being connected to one another by way of the two inner arms. Two U-shaped tension arches connect the two inner arms to one another, so that the container is centrally positioned between the two U-shaped tension arches, which the two outer arms being able to be pressed together gradually and repeatedly for providing dosing of the desired substance.

A thermally insulating flask having two containers of flow-pressed aluminum, wherein an inner container is placed inside and at a distance from an outer container. The inner container forms a flask neck at the top of the inner container, which is connected in an air-tight manner with the outer container. Both containers are connected at the top by a material of low thermal conductivity, for example chrome-nickel steel, in an air-tight and rigid manner. The connecting piece can be constructed from a composite-plated chrome-nickel steel laminate, in which the aluminum layer has been removed by a lathe, leaving two collar rims, to allow welding to the aluminum containers, while the remaining chrome-nickel steel layer forms the mechanical connection which has low thermal conductivity.

The grippers are mounted on a doffer bar so as to disengage from both the top and bottom of the bar should a mis-alignment occur relative to a bobbin tube. The removal or separation of a gripper from the bar causes a pneumatic or electrical signal to be generated which can be used to indicate the individual disturbance location. A light may also be provided at each gripper station in order to indicate a position of a disturbance.

An air pump is configured as a reciprocating compressor. On a fuel tank, there is fitted a cylinder of the air pump, in which an axially displaceable piston rod, having a handle and a piston, is coaxially disposed. The piston divides the interior of the cylinder into two chambers. The lower one of these chambers, lying closer to the fuel tank, communicates with the fuel tank via a first one-way valve, which permits only the entry of air into the fuel tank. The upper one of these chambers, lying farther from the fuel tank, communicates unchecked with the atmosphere. The one-way sealing of the piston against the cylinder allows the passage of air past the piston only in the direction from the upper chamber to the lower chamber. The piston rod is provided with a coaxial duct and a second one-way valve which is opposed to the first. The two chambers are able to intercommunicate via the coaxial duct and the second one-way valve, which, from a predetermined pressure, allows air to escape to the atmosphere.
摘要:
A ring spinning machine comprises at least one group of spinning stations or points (11) arranged adjacent each other at equal intervals, a bobbin change device (14) for simultaneous replacement of full bobbins (15 ) spooled with yarn by empty bobbins (16) at each spinning point (11) and an endless conveyor (17) which extends along the spinning points (11) and is led from one end of the spinning point group (12) to the other back on itself and on which at the interval of the spinning points (11) upright bobbin pegs (13) are arranged in such a manner that in a bobbin change position of the endless conveyor (17) each spinning point (11) is exactly aligned with a bobbin peg (13) associated individually therewith. Each bobbin peg (13) is arranged on its own peg support tray (18). Associated with each peg tray (18) is a driver (19) which is adapted to be brought into entraining engagement therewith and which is disposed on the endless conveyor ( 17) in such a position that when the driver (19) is in entraining engagement with the associated peg tray (18) the bobbin peg (13) of said peg tray (18) in the bobbin change position of the endless conveyor (17) is exactly aligned with the associated spinning point (11).
