Title: Winding-up device
IPC: B60R22/46
Filed: 1975-04-11
Abstract: 1465419 Propelling winding drums SOC NATIONALE DES POUDRES ET EXPLOSIFS 11 April 1975 [25 April 1974] 15070/75 Heading B8B [Also in Division A3] An elongate flexible element, e.g. a vehicle safety belt, is wound up by a device comprising a drum 1 rotatable about a fixed axle 7, rapid winding being effected e.g. in a vehicle collision by firing a pyrotechnic charge 5 which drives a piston 3 to the left end of the device such piston engaging with both an axial groove or grooves 1a in the drum and a helical groove or grooves 10 in the axle so as to effect rotation of the former. The charge may be ignited electrically by a collision detector. At least one of the grooves (or sets of grooves) is interrupted in the initial position of the piston, to allow spring 2- controlled rotation of the drum under normal conditions, and in the final position of the piston, whereby the continued rotation of the drum winds in the belt while its kinetic energy is dissipated. A non-return device comprises a toothed ring 13 on the drum which is released to engage a fixed ring 16 when the piston is driven to the left. Two such winding devices may be mounted together in a vehicle or two drums may have a common axle and pyrotechnic charge, in which case the respective helical grooves may be oppositely inclined.

Filed: 1943-09-15
Abstract: 568,340. Turning - gear. WEST, H. E. W. Sept. 15, 1943, No. 15124. [Class 7 (v)] An auxiliary, starting engine coupled to the main engine by a centrifugal clutch, is controlled by an electric switch 2 movable from the " Off " position shown through a " Running " position 3 in which the engine runs slowly to an " Engage " position 4 in which the engine is speeded up and actuates the clutch to start the main engine. In operation, the switch 2 is moved to position 3, permitting a battery 1 to excite a solenoid 14 adapted to open the fuel supply to the auxiliary engine, a solenoid 15 actuating the ignition of that engine and, if desired, a solenoid 16 in a relay circuit controlling the priming pump of the main engine. A push-button 11 in circuit with a solenoid 8 is then depressed to excite the solenoid and close a switch 7 controlling the starter mptor 6 for the auxiliary engine. When the engine has warmed up, the switch 2 is moved against spring action to position 4 and held there. In this position, previous contacts are maintained through a lead 17 and a solenoid 19 is excited to open the throttle of the auxiliary engine which speeds up until it closes the friction clutch coupling it to the main engine. On releasing the switch from position 4, it flies back to position 3. Specification 565,336 is referred to.

Title: Improvements in or relating to compressors
IPC: F04D19/02
Filed: 1949-06-09
Abstract: 692,188. Axial-How compressors. STALKER, E. A. June 9, 1949 [June 21, 1948], No. 15388/49. Class 110(i) An axial-flow compressor comprises rotor passages each having an exit larger in cross-sectional area and radial depth than the inlet to the passage. In a multi-stage compressor each rotor passage 19, Figs. 1 and 2, expands downstream with increasing radial height, the divergence being given to both the inner wall 23 and the outer wall 25, as shown, or to the outer wall only. Successive passages 19 may decrease in axial length, as shown. The rotor blades 21 are straight and parallel. The stator passages 29 expand over the substantially straight portions from B to C and then contract over the curved portions from C to D so as to provide an acceleration which avoids separation of the boundary layer. at the convex side of the stator blades 27. Alternatively, each stator passage may decrease in radial height from inlet to exit. The ratio of hub diameter to, tip diameter is preferably not less than 0.85 but may be made smaller, say 0.7, by curving at least a part of each rotor blade. The trailing edges of the rotor blades may be twisted so that less whirl velocity is imparted at the tip than at the root. The trailing edges of the stator blades may be twisted to permit the rotors to perform equal work at the root and tip. To reduce the overall diameter, the rotor diffusion may be less in the earlier stages than in the later stages, e.g., the ratio of exit area to inlet area may be 1.25 for the first rotor, increasing progressively to 3 for the last rotor. The blades may have faired leading portions, as shown in Fig. 5.
