Patent GB-1261644-A (GB)
Title: Container capping machine
Inventor: WELLER ARTHUR W
IPC: B67B3/20
Filed: 1969-03-08
Abstract: 1,261,644. Stoppering. RESINA AUTOMATIC MACHINERY CO. Inc. 8 March, 1969 No. 12332/69. Heading B8T. A container capping machine of the type described in Specification 828,998, with a continually moving conveyer, in which a screw cap is applied to a container on the conveyer by counter rotating friction rollers (36), Fig. 5 (not shown) and 37, includes an automatic adjusting mechanism such that the axis of rotation of the rollers moves to compensate for wear of the peripheral rubber tread. The automatic mechanism operates as the reduction in diameter of each of the rollers e.g. 37, monitored by the roller bearing (90), Fig. 3 (not shown), causes the axle 88 held in a link 78 to rotate clockwise about the pivot 75 under the influence of spring 85. The moving axle 88 engaging a slot 72 in a spool 69 causes the spool axle 63 to move longitudinally so adjusting the position of the cam follower 66 on the cam surface 67. This allows the frame 53 carrying the roller axle 38 to rotate anti-clockwise about the pivot 52 under the action of the spring 60 so adjusting the position of the roller axle as tread wear occurs. The initial position of the roller axle is set manually by means of a threaded axle 41 attached to a fixed support 39, rotation of the axle moving the automatic mechanism along the support.

Abstract: 985,967. Fluid-pressure brakes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 28, 1961 [April 7, 1960], No. 12467/60. Heading F2F. A braking system has means operable on excess deceleration to lock the applying means against an increase in application and to relax the braking means. When a brake drum 2 is braked violently an inertia ring 9 resiliently supported on springs 10 moves axially to close a switch 11 energizing a relay 12 to unlatch a pawl 13 and allow brake fluid pressure in a cylinder 16, between master cylinder 5 and brake cylinder 8, to depress a piston 15, thereby shutting a spring-loaded valve 17 in the brake line from the master cylinder and increasing the volume in the line to the brake cylinder 8. A capsule 22 is contracted against a spring 23 by engine vacuum through passage 24, but movement of the piston 15 closes a switch 25 to energize a relay 26 to open an atmospheric valve 29 and allow the spring 23 to expand the capsule to reinstate the piston 15. To prevent excess vacuum drain the pawl 13 closes a valve 31 during operation. It is stated that the system may be wholly hydraulic or electro-mechanical and capsule may be pressure operated against an external spring. The deceleration sensing means may comprise a plate and may include a quick-start thread.

Title: Improvements in high frequency electrical oscillators
IPC: H01J25/587
Filed: 1941-10-03
Abstract: 588,916. Magnetrons. SAYERS, J., and WRIGHT, C. S. Oct. 3, 1941, No. 12853. [Class 39 (i)] In a magnetron of the kind in which a plurality of coupled resonators of the same natural frequency open into a space in which the cathode is located, the number of possible modes or frequencies of the generated oscillations is limited by the provision of electrical connections or " straps " between selected points on the resonator system. If there are end spaces, as in Specification 588,185, the straps may be located in these. Alternatively, they may be in a circumferential groove cut in the anode segments some way along its axial extent; where the resonators are built up of laminations, the groove may be made by modifying certain laminations and the straps may be incorporated in some of these laminations during manufacture. In the preferred mode of oscillation alternate anode segments are strapped together, and the two groups oscillate in opposition. This may be'done by simple circular 'connections, one in each end space; or duplicated at each end to avoid axial fields ; or a strap 16, Fig. 6, may connect three A segments in one end space, and strap 15 two A segments in the other end space ; or short straps 23, 24, Fig. 8, may be in echelon. The output connection may be made to one of the straps. The resonators may be cylinders or slots and may be arranged in a straight line opposite a plane cathode. According to the Provisional Specification, one group of alternate segments may be kept at constant potential, while the members of the other group are strapped so as to oscillate alternately in opposition. The modes of oscillation are discussed in detail.
