摘要： An improved mixing apparatus for mixing a liquid and a particulate solid material within a container such that the pigments and/or other solid particulate materials, which are initially precipitated out and usually accumulated at the bottom of the container, are rapidly and thoroughly mixed and dispersed throughout the liquid in a uniform manner such that substantially all of the particulate material is dispersed within the liquid. In one embodiment, a flow pattern in the form of an inverted vortex rising from the bottom center of the container is created by a rotating frusto-conically shaped impeller to pull the particulate material away from the bottom of the container. In another embodiment, the apparatus includes a cover mechanism, which is made to function integrally with the mixing apparatus, and which covers the container during the mixing operation to prevent the escape of fumes or spray. The cover mechanism is further provided with an access portion which is operable to allow ready access to the interior of the container without removal of the cover mechanism and which permits the taking of samples of the liquid being mixed well as convenient and ready access for other purposes during the mixing operation.

摘要： To drill small holes in a metal component having a non-conductive, e.g. ceramic, surface layer apparatus is provided capable of carrying out both ultrasonic and EDM drilling operations without dismounting the component. The drilling operation commences with an ultrasonic drilling phase and change over to essentially EDM operation when breakthrough of the ceramic surface layer is detected. Breakthrough is detected by applying a low voltage pulse signal to a drilling electrode and sensing when current starts to flow between the electrode and the workpiece. When a multiplicity of holes are drilled simultaneously the changeover to EDM is triggered by breakthrough of the first electrode but may be delayed to permit the remaining electrodes to breakthrough.

摘要： An arrangement for releasably retaining a telephone apparatus in a standby condition includes a handset including an earpiece and a base having a shelf portion for receiving the earpiece. A hooking post member protrudes through the shelf portion and includes an integral spring to enable the hooking post member to be resiliently movable towards and away from the shelf portion. A switch hook which is separate from the hooking post is arranged to be actuated by the earpiece when the earpiece is brought into engagement with the base. When the earpiece engages the base shelf portion, the hooking post member is resiliently urged into contact with the earpiece for releasably retaining the earpiece on the base. A guide on the base prevents the hooking post member from twisting or rotating.

摘要： The material removal rate of a creep-feed grinding operation may be increased significantly by use of a type of porous grinding wheel in combination with jet of coolant liquid at high pressure directed at the periphery of the wheel in advance of the cutting point. The apparatus for performing the method may comprise a multi-axis machining centre adapted to enable the coolant nozzle(s) to be retracted to provide working clearance for automatic tool changer operation and to re-position the aiming point of the nozzle(s) over an angular range relative to a cutting point.
