Title: Improvements relating to the regulation of the pressure in the induction piping of internal combustion engines
IPC: F02M69/00
Filed: 1945-11-21
Abstract: 617,967. Fluid-pressure servomotors. BENDIX AVIATION CORPORATION. Nov. 21, 1945, No. 31344. Convention date, Nov. 18, 1944. Addition to 611,909. [Class 135] [Also in Group XXVII] The arrangement described in the parent Specification is modified by the addition to the regulator of means for manually varying its datum operated by a lever 218, and by the interconnection, by an operating rod (not shown) of the lever 218 with the manuallyoperated throttle valve of the parent Specification. As shown, the datum of the regulator is varied by varying the pressure of a spring 80 by operation of the lever 218. When the throttle valve is opened the lever 218 moves to relieve the pressure of the spring, thus raising the boost pressure necessary to bring the regulator control valve to a neutral position. The lever 218 is carried by a shaft 203 mounted in an eccentric bearing sleeve 204. The end of the shaft opposite to the lever carries an eccentric portion 201. The eccentric portion has rotatably mounted on it an anti-friction roller bearing 200. A spring 210 is arranged to tend to rotate the shaft so that the bearing 200 is forced against a member 82 which has a flange 81 engaging the spring 80. When the lever 218 is turned anti-clockwise (Fig. 4), the roller bearing applies pressure to the member 82 and compresses spring 80, thus reducing the pressure setting of the regulator. The eccentric sleeve 204 can be rotated to vary the position of the shaft 203 and may be locked by a screw 235 passing through a slot in its flange 230.

Title: Improvements in or relating to building construction
IPC: E04B2/66
Filed: 1945-11-26
Abstract: 612,720. Floors; roofs; walls. PIPPARD, W. R. M. Nov. 26, 1945. No. 31860. [Classes 20(iv) and 87(i)] A wall unit is of rectangular form and has flanges on all four sides, the upper flange having a splayed underface which engages a correspondingly formed flange on a horizontal member of the frame by which the units are supported. The top and bottom flanges have formations which interlock on adjacent units in the wall. Fig. 3 shows two wall slabs 6, Fig. 2, in tongue and groove engagement 10, 12, with each other along their top and bottom edges, the underside 9 of the top flange of each slab being sloped to hook over a corresponding part on the horizontal frame member 3, Fig. 6. The faces with the tongues and grooves 10, 12 and the top face of the bottom flange of each slab may also be sloped parallel to the face 9. The vertical flanges 7 of the slabs 6 fit into a common channel 30 in the uprights 2 and the floor and roof slabs are similarly jointed to their supporting beams, except that the channels in the roof beams are made progressively deeper along their length to provide gutters 25, Fig. 14, which lead to eaves gutters. Water collecting in the grooves of the frame members 3 may also be diverted into drains. Metals, asbestos cement or plastic slabs may be used with channelled concrete, steel, aluminium or wood frames, or with metal or asbestos cement channels attached to or lining grooves in the frame members; non-load bearing vertical jointing members in the walls may be of light channel section. Floor and roof slabs flanged on two edges may be used with joists running. in one direction only, or slabs flanged on all edges, with joists running in both directions and supported on blocks or columns where their ends meet.

Title: Improvements in or relating to guards for heavy power presses
IPC: F16P3/04
Filed: 1946-10-28
Abstract: 621,169. Machinery safety devices. ART METAL CONSTRUCTION CO., HUTSON, A. E., and TELLING, C. T. Oct. 28, 1946, No. 31987. [Class 80 (iv)] Initial movement of the clutch operating pedal 1 of a power press allows a guard 9b supported on a balanced arm 9a to fall into the safety position, a pin 6, Fig. 3, on a rod 6a connected to the arm 9a being released by a catch 5 operated by an arm 3 coupled to the pedal 1. The guard is locked in the safety position by a catch 9 engaging a pin 8 on the rod 6a and at the same time a latch 12 coupled to the rod uncovers a hole in a bracket 13 to allow a clutch extension rod 14 to be moved to permit further actuation of the .pedal 1 to effect engagement of the machine clutch through a rod 21. Thus if the guard is not closed or is obstructed the clutch engagement is prevented. When the working stroke is almost completed a cam 11 on the main shaft 11a releases the catch 9 and lifts the guard by acting on an extension 9d of the arm 9a. The rod 6a moves down and the catch 5 reengages with the pin 6, a part 4 of the catch 5 having been previously dis-engaged from a projection 4a on rod 3a connected to arm 3 of lever 1. While the ram of the machine is on its upward return stroke a cam member 15 holds up the latch 12 until operated by a bracket 16 attached to 'the ram at the top of the stroke. This device ensures that completion of the upward movement of the ram can be effected in the event of the pedal 1 being momentarily released. As the ram completes its upward movement a catch 18, Fig. 1, on an arm 18a is operated to lift a hook 20 coupling top and bottom portions of the clutch actuating rod 21 thus allowing the top portion to move upwards to release the clutch and stop the machine. When the pedal 1 is released the lower part of rod 21 moves upwards to re-engage the hook 20' of the upper part and the part 4 of catch 5 reengages with projection 4a so that the mechanism is reset for a further working operation. A hand lever 2 is coupled to pedal 1 for alternative hand operation.

Abstract: 1,241,036. Laminated structural elements. R. W. GRAFF. 5 July, 1968 [6 July, 1967], No. 32252/68. Heading B5N. A structural element comprises a plate member with spaced reinforcing ribs which are hollow and filled with solidified flowable material 4. The plate member is formed of two layers of fibre-reinforced plastics, e.g. polyester or epoxy resin, between which flattened plastics tubes, or pairs of strips, e.g. of polyvinyl alcohol, polypropylene, polyamide or polyester, are laid where the ribs are required. Reinforcing strips or wires 5, e.g. of metal, may be arranged above and below the tubes, or the tubes may be surrounded by a fibrous reinforcement, e.g. of glass fibres. Subsequently, either before or after hardening of the material of the plate itself, and if required on the site itself, flowable material, such as plastics or glass foam, plastics fibres or concrete, is forced into the tubes to expand them and produce the ribs. Alternatively, the tubes or strips may be removed prior to the insertion of the flowable material. The plate member may be corrugated where the tubes or strips have been inserted as shown in Fig. 4, so that when the tubes are expanded by the flowable material, the expansion takes place mainly on the one side, and the other side remains substantially plane. If desired, the tubes may be pre-expanded, before the insertion of the flowable material, by a solid rod which is subsequently removed or by a rigid tube, preferably perforated throughout its periphery, which can remain in place when the flowable material is inserted.
