Title: Improvements in and relating to endless belt conveyors
Inventor: CLARK DONALD
IPC: B65G39/14
Filed: 1961-07-27
Abstract: 955,855. Endless belt conveyers. DISTINGTON ENGINEERING CO. Ltd. July 25, 1962 [July 27, 1961], No. 27238/61. Heading B8A. Each return roller 16 of an endless conveyer belt assembly is supported in a support structure consisting of a pair of rigid L-shaped side members whose vertical limbs 20 are secured to tensioned side ropes 14. Horizontal limbs 21 are hinged together at 22 and have cleats 24 secured to them. Each cleat has a vertical slot 25 which can be closed at its upper end and which receives an end of a shaft 23 for supporting a roller 16. Part of the shaft ends have parallel flats for engagement with the slots 25 and rotation of the shaft is prevented. Some axial movement of the shaft relative to the cleats is permitted due to the length of the parallel flats but the ultimate ends of the shaft are too large to pass through the slots. In operation, the support structure allows the ropes 14 to move towards and away from each other but maintains the return roller 16 horizontally. The shaft may have square ends which engage square holes in the cleats. Split pins may be used to prevent the shaft ends from slipping out.

Filed: 1936-10-08
Abstract: 482,896. Ignition systems ; preventing unauthorized use of vehicles. FRIEND, F. F. Oct. 8, 1936, No. 27337. [Classes 7 (ii) and 7 (iv)] At a predetermined speed of the vehicle, a resistance 1 is automatically inserted in series in the ignition system primary circuit. A switch-arm 4 normally retained by a spring 22 on the contact 2 is drawn by the action of the governor 7 on to contact 3. The speed of the governor shaft 10 depends on road speed, irrespective of the gear relation with the engine. A lock-switch 25 may also be provided for short circuiting the resistance 1, and may be secretly disposed; if left in the off-position an unauthorized user of the vehicle may be the more readily apprehended.

Title: Improvements in or relating to pressure transducers
Inventor: WERNER FRANK DAVID
IPC: G01L9/00
Filed: 1962-07-19
Abstract: 949,433. Measuring pressure electrically. ROSEMOUNT ENGINEERING A. G. July 19, 1962, No. 27900/62. Heading G1N. A pressure transducer comprises a ring shaped body wall 10 closed at at least one end by a cap 11 a part of which includes a relatively thin flexible section 11A, a pressure inlet 21, a diaphragm 18 which is supported from the ring 10 by a wall 16 itself thinner than the diaphragm 18 and the ring 10, and means, such as differential condenser plates 40, 41 which form a transducer sensitive to diaphragm movement. Two pressure tight spaces divided by the diaphragm 18 are defined by the members 10,11 and a cup member 12 which are welded at 29. Condenser plates 40, 41 are arranged to have the same stiffness as the diaphragm 18 so as to render the assembly insensitive to axial acceleration, and each comprise a metallic disc 42 (Fig. 5) concentrically spaced from a metal ring 44 by glass connectors 46. Metal suspension elements 48 arranged to have the same co-efficient of thermal expansion as the wall member 16, are welded to each ring 44, and by dimples 48A, 55A to the ring 10 so as to support the plates, parallelism with the diaphragm being ensured during this operation by removable T-shaped plastic spacers 52. Lead wires 37A, 37B soldered to plates 40, 41 are brought out through metal tubes set in glass insulators 34. Pressure applied through connections 21, 25 results in upward or downward movement of the diaphragm 18 but deflections of the relatively massive cap are effectively isolated from the ring 10 by the flanged section 11A. Absolute or differential pressures may be measured depending upon whether the space 30 is evacuated and the connector 25 sealed off, or whether both connectors are utilized. Constructions utilizing only one "fixed" condenser plate 40 are envisaged and in an alternative embodiment (Fig. 9 not shown) the condenser plates are made from fused quartz, metallically coated. In a further embodiment (Fig. 10 not shown) a massive pressure tight case has suspended from its cap a ring shaped member within which the diaphragm and condenser plates are attached.

Title: Improvements in or relating to blower casings for air-cooled internal combustion engines
IPC: F02B33/00
Filed: 1955-09-30
Abstract: 783,030. Centrifugal blowers. SUDDEUTSCHES JLO WERK GES. Sept. 30, 1955 [Oct. 16, 1954], No. 27934/55. Class 110(1). A blower for the air-cooling of a reversible internal combustion engine comprises an impeller 5 disposed eccentrically to a part-circular casing 1 so as to be in sealing relation to the casing, except for a small gap 7, on the side away from the discharge aperture 4, and the casing is sub-divided vertically to the plane of rotation of the impeller, preferably in the plane of symmetry of the casing, by a deflector 8 which extends into the aperture 4 and has a sealing action against the impeller periphery and the casing. This construction permits the blower to operate in either direction of rotation. For example, when rotation is in the direction of the arrow, air is discharged through the casing part 9 to the left-hand part of the aperture 4 in the usual manner, while air accumulates in the part 10 and returns in opposition to the direction of rotation towards the right-hand part of the aperture 4. The deflector 8 may be of cast or sheet metal or may be die-cast integrally with the casing 1. It is stated to be known to make the casing with two symmetrical halfspirals, a deflector member supplementing one or the other half-spiral, depending on the direction of rotation, to form a complete spiral.

In a modification, Fig. 3, the spigot 11a is hollow and has an annular bead 12 which co-operates with the underside 13 of the plug to prevent accidental removal of the cap. The cap and neck may have screw threads.
