Abstract:
A needle safety guard device adapted to attach to a liquid container is provided. The device includes a disk-shaped shield having a medial opening connected with a radial opening between two radial edges. The device also includes a substantially U-shaped holder having two sidewalls coupled substantially perpendicular to the disk-shaped shield along the two radial edges, and a top cover connecting to the two sidewalls and extending from the shield above the radial opening. The U-shaped holder includes a wedged protrusion and a curved protrusion extending from each of the two sidewalls, the curved protrusion being between the top cover and the wedged protrusion for blocking a cap of the liquid container from moving toward the medial opening.
Abstract:
An anchor tube for an injection-securable anchor includes a through-opening (13) for receiving a fastening element (8) and at least first connection element (32) provided on at least first end (14) of the anchor tube (12) for securing, on the anchor tube (12), a further part of the injection-securable anchor (11).
Abstract:
A shield support for underground mining has a slider and a roof bar between which a ram is arranged, with an inclination detector being provided with which the inclination of the roof bar can be measured.
Abstract:
A method is proposed for measuring thickness and detecting double and missing sheets during the sheet feed to a sheet-processing machine, such as a sheet-fed printing machine. A corresponding monitoring apparatus has one or more sensing elements above or beneath the sheet stream. The sensing element can be displaced, with an actuating device having an actuating drive, in the direction towards and away from the sheet stream. The actuating drive has at least one piezoelectric actuator or it is formed by the latter.
Abstract:
In an apparatus for operating a valve element consisting of a base, an operating lever pivotally journalled with respect to the base and a drive apparatus which is secured to the base and engages the operating lever which has at least one of its ends for operating on the valve element, the drive apparatus comprises two piezo-electric transistors which are secured with a nonparallel orientation between the base and the operating lever such that they are each moveable relative to the base and the operating lever about an axis parallel to the pivoting or rocking axis of the operating lever.
Abstract:
The operation of an electromagnetic valve is monitored by connecting the coil of the valve to a d.c. source for a period of time sufficient to permit the current in the coil to reach its maximum steady state value then disconnecting the coil to permit the current to fall and re-connecting the coil to the source again and measuring the current which is established in the coil.
Abstract:
In the method and installation for determining a relative distance between the front wall (22) of the cylinder and the piston (14), an ultrasonic converter (30) is used to which a plate (68) presenting a reflecting reference surface (66) for the formation of a reference path is secured. The group of reference oscillations (R) and the group of measurement oscillations (M) appearing in the output signal of the converter (30) after the emission of a group of transmitter oscillations (S) are detected by means of threshold switches (108, 120, 122). Thereby, a measurement signal and a reference signal are obtained, the latter being used for compensation by means of a processor (38) for the influence of the different propagation conditions affecting the measurement signal.
Abstract:
A metering valve has a closable discharge opening from which liquid drops can be discharged, wherein a beam device is provided which generates electromagnetic radiation.
Abstract:
A sanitary disposable urine device is provided that includes an inner ring and outer ring each having a top surface and opposing bottom surface. The outer ring is substantially concentric with the inner ring and may be offset. At least one of the top surfaces of the inner and outer rings conforms to a body contour of a user's perineum. The device includes a hand holder coupled to the bottom surface of the inner ring, the hand holder having an opening configured to match to the inner ring. The device includes a fluid containing bag having an open end attached to the hand holder such that fluid flows through the inner ring and the opening of the hand holder into the fluid containing bag during usage. The device includes an inner bag inside the fluid containing bag having an absorbent material and an outer sealable bag to secure the device after use.
Abstract:
The invention relates to an LED module (1) comprising at least one light-emitting diode (LED) (3) and at least one heat sink (2) for active cooling, having at least one coolant channel (6) through which a cooling fluid flows.The dimensions of the at least one coolant channel (6) are selected so that a predominantly laminar flow of the fluid is set up in the at least one coolant channel (5) during operation of the LED module (1).
