Title: D.C. brushless motors
IPC: H02P5/50
Filed: 1981-05-18
Abstract: Switching amplifiers (30') respond to the angular position of the rotor in a first D.C. brushless motor (30) to change the sense of current flow through the energising coil of the motor.

Title: Bar feeding apparatus
Inventor: DIXON REGINALD JOHN
IPC: B23B13/02
Filed: 1981-07-22
Abstract: An automatic self contained bar replacement mechanism for application to single spindle and multi spindle bar lathes and other machine tools is equipped with a feed finger mechanism for bar advancement during normal automatic cycling. The replacement mechanism covered includes bar magazines 4, a cam and lever operated bar escapement releases one bar at a time into a pivotted bar chute 24a leading to one or more opening type "U" shaped stock tubes 21. These have associated levers 23 and longitudinal strips 22 for closing them. The strips are locked by spring pressure so reducing vibration and noise to the minimum. An electric motor drives a cam with a follower Causing a dog clutch to engage and push the "U" tubes to disengage them from taper pins. Cams and levers cause pivoting of the strips for opening and closing. The mechanisms of mechanical type using electric motors for driving camshafts with sequence control by plug-in type limit switches. The "U" type stock tubes are single piece units and can be readily changed for different size bar stock. One type of closing strip only is required. The automatic replacement of hexagon as well as circular section bars is achieved by the orientation of the bars into machine chucks for machining. <IMAGE>

Patent GB-2098277-A (GB)
Title: Spring applied brake control arrangement
IPC: B60T7/04
Filed: 1980-10-06
Abstract: A brake control arrangement (30) permitting normal service brake actuation through a brake linkage (10) and providing automatic brake actuation in case assisting fluid pressure decreases. During normal operation, sufficient assisting fluid pressure is supplied to a pressurizable chamber (42) to move an actuation piston (34) to its non-actuation position against the biasing force of a spring (36). When fluid pressure falls below the pressure needed to counteract the spring's biasing force, the spring (36) displaces the piston (34) to an actuation position relative to a surrounding housing (40) and, during its displacement, displaces a brake engagement plunger (32) to its brake engaged position. Movement of the utilizing apparatus may thereafter be provided by axially displacing an engagement member (48) against the actuation piston (34) so as to drive the actuation piston (34) to its non-actuation position. The engagement member (48) has an indentation (48b) which accepts displacement of the plunger (32) thereinto and permits subsequent brake actuation by the brake linkage (10).

Inventor: KIRMAN RICHARD GEORGE
IPC: G01L5/22
Filed: 1983-10-24
Abstract: Modern automatic machinery often incorporates equipment for grasping/gripping an object. An automatic machine requires feedback enabling it to monitor eg. by means of pressure the exact manner in which it is holding the object. For use as the active ingredient of a pressure sensing system, a solid-dielectric capacitor is provided, wherein electrically connecting the dielectric 4 to one of its electrode plates 2 is a shaped electrically conductive body 1 that is deformable to vary its area of contact with the dielectric. The body 1 is constituted by a blob of mercury that deforms when pressure is applied to electrode 2. Alternatively, the body 1 may constitute the electrode or may lie atop a strip-like electrode to be deformed over its edges. The electrodes 2, 5 are connected to a bridge or tuned circuit. Individual pressure sensor elements can be interconnected to form strips of elements, which in turn can be arranged side-by-side to form area sensor devices. <IMAGE>
