Title: Improvements relating to Wire Conveyor Belts
Inventor: MORRIS IVOR ST LAWRENCE
IPC: B65G17/06
Filed: 1967-10-28
Abstract: 1,171,216. Endless conveyer belts. GEORGE LANE & SONS Ltd. 24 Oct., 1968 [28 Oct., 1967], No. 49077/67. Heading B8A.

Title: Electric drive mechanisms for two coaxial, contra-rotating propellers of a ship or the like
IPC: B65H23/24
Filed: 1967-10-30
Abstract: 1,147,504. Electric motor driving arrangements. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. 30 Oct., 1967 [22 Nov., 1966], No. 49149/67. Heading H2A. In a propulsion system for ships &c. using concentric contra-rotating propellers driven by the oppositely rotating members 12, 22 of a synchronous motor 13, the use of slip-rings or rotary transformers for feeding A.C. power to the member 12, is avoided by the use of an induction motor 15 whose rotor 14 feeds slip energy to this member. The induction motor is of much lower pole-number than the synchronous machine, so that it operates at very high slip, and thus feeds most of its energy into the synchronous machine. This slip may be slightly greater or slightly less than unity depending on the rotational senses. The reactive power may be supplied by the machine 13 or from outside. The pole-wheel 22 of the synchronous machine is excited via slip-rings 23. A flywheel may be used to increase the inertia of the inner member to the value of the outer member.

Abstract: 1,163,556. Tyre building machines. GENERAL TIRE & RUBBER CO. 7 Nov., 1966 [6 Dec., 1965], No. 49788/66. Heading B7C. In a tyre building machine comprising a tread and breaker transfer ring 3 movable between a tread and breaker assembly drum 2 and a carcass shaping drum 1 means for centering the ring 3 about the drum 1 or 2 include a piston and cylinder of which one component is immovably connected to the ring, the other being able to be fixed relative to the associated drum 1 or 2 whereby actuation of the piston/cylinder assembly causes the ring to move until it is arrested by abutment of a stop rod 67 on the ring with a fixed stop 57. The ring may be held in position after centering by maintaining fluid pressure on the piston or by mechanical means (not shown). As shown the transfer ring 3 is connected to the cylinder 103 and is moved along overhead rails 4 by a motor driven chain 5 fixed to the piston-rod 107 and carrying a cam 89 for tripping an appropriate limit switch 85 to disengage the drive when the ring is adjacent drum (1) or 2.

A switching arrangement for connecting any one of a number of outlets to any one of a number of inputs comprises a number of switch assemblies equal to the number of outlets. Each assembly comprises an insulating plate 1, Fig. 1, having a number of holes 4, arranged in a circle, and a series of bare rods 5, Fig. 2, extends through these holes, each rod passing through the corresponding hole in each assembly. Each assembly also includes a ring 2a of insulating material carrying a ring 2 of conducting material, the latter having a spring blade 8, for engagement with the bare rods 5, and a projecting portion 12 for engagement with a fixed, ring-shaped contact mounted on the reverse face of the adjacent plate 1, and forming an outlet connection. By rotation of each ring 2a it is thus possible to connect the corresponding outlet to any desired input rod 5, through the blade 8. A resilient projection 10 on the rotatable ring engages between adjacent rods to locate the ring in any set position. If desired, the contact ring 2 and the fixed output contact may each be divided into three, mutually insulated segments, to provide three separate outlets.
