Title: A device for preventing torpedoes from sinking beyond a predetermined depth
IPC: F42B19/38
Filed: 1930-09-01
Abstract: 353,301. Torpedoes. SILURIFICIO WHITEHEAD DI FIUME SOC. ANON., Fiume, Italy. Sept. 1, 1930, No. 26069. Convention date, Aug. 30, 1929. [Class 9 (ii).] Relates to torpedoes the buoyancy of which is reduced by the ejection of compressed air under the control of an hydrostat, when the torpedo sinks beneath a predetermined depth, the object being to cause the torpedo to come to the surface to facilitate its recovery. According to the invention, the compressed air is ejected through nozzles directed rearwards, so that, the torpedo being then inclined upwards, the reaction of the air jets helps to urge the torpedo to the surface. As shown, the rearwardly directed nozzles 6, Fig. 1, are in communication with a space 7 between the front end 8 of the compressed air receptacle 3 and a similarly shaped partition 9; and the hydrostat 44, Fig. 3, is arranged at the upper end of a rod 40 attached to a transverse frame 33. The hydrostatic diaphragm 44 is controlled by a spring 42 and is provided with a lever 48 hinged at 58. The bottom end of the frame 33 is connected by a rod 34 to a shoe 36 pivoted at 37. When the torpedo is in its launching tube, the shoe 36 prevents any movement of the hydrostat ; but after the torpedo is launched, the shoe is free to swing out and the lever 48 is urged outwards by spring 59. Hence, if the torpedo sinks below a predetermined depth, the hydrostat is depressed and the frame 33 drives a plunger 39 down against a pair of togglelinks 25, 23 which compress a spring 28 on one side and displace a piston 19 on the other side. The head 20 of the piston 19 bears on the end 15 of the spindle of a pilot valve 14, which is opened bv the displacement of the piston 19. Compressed air then passes from the reservoir 3 through a port 16 and the pilot valve 14, and opens a main differential valve 12 ; after this compressed air passes also through a port 17 and then through a port 21 in the piston 19 and a port 56 in the casing 18 of the piston to a valve 54, which it forces open against a spring 55. The compressed air then passes through this valve to the space 7 and thence to the nozzles 6. The lever 48 in swinging out when the hydrostat is depressed brings a tooth 53 on the lever into locking engagement with the cover 51 of the hydrostat, which is thus held depressed until the lever is pushed back by hand.

Abstract: 990,146. Electric switches. E. SCHEUBECK, [trading as MASCHINENFABRIK, REINHAUSEN GEBRUDER SCHEUBECK KOMM.-GES.]. July 4, 1963 [July 4, 1962; July 12, 1962], No. 26535/63. Heading H2B. [Also in Division H1] Transformer tap-changing (see Division H1) is effected for each phase U, V or W by four circular groups of tapping contacts 1-15, 2-16, 17-31 and 18-32 (Fig. 2) each group having a contact bridge member 62 or 63 by which the selected tapping is connected to the load change-over switch 51. The contact bridge 62 is secured to a Maltese wheel 69 (Fig. 4a) which, on tuning stepwise, carries 62 round a circular path connecting contacts 1-15 in turn to a stationary contact-ring 66. Similarly contact bridge 63 is carried by a second Maltese wheel 70 (Fig. 4b) which, during tap-changing in the lower numbered contact range 1-16, moves alternately with wheel 69 and the load changeover switch 51 which latter effects the on-load switching of the load circuit to the new tapping selected by the contact bridge carried by wheel 69 or 70. During tap-changing in the higher numbered contact range 17-32 by similar mechanisms in 53 the contact bridges 62, 63 remain stationary in contact with contacts K 1 , K, which are connected each to a different side of the load change-over switch 57. The contact bridges 62, 63 are connected through the contact rings 66, 67 to corresponding contact rings in the similar tap selector mechanisms in 53 and thus through the associated contact bridges to the tapping contacts selected by those bridges. To allow each Maltese wheel to remain stationary at the appropriate times it is provided with a cutout portion 76 (Figs. 4a and 4b) which, when opposite the operating crank 59 enables the latter to rotate without moving its associated Maltese wheel which is held by a catch 89. At the appropriate point a cam 84 or 85 driven from the crank 59 by gearing 86 releases the spring- pressed pawl 77 which is pivoted to the Maltese wheel so that a finger 79 on the pawl forms with the wheel an additional roller slot 75<SP>1</SP> (Fig. 4b) through which the driving pin 74 on the underside of crank 59 can then turn the wheel. The Maltese wheel mechanisms are driven by jointed shafts 57, 58 from driving gear in switch head 56.

Abstract: 1470808 Shaft couplings POLAROID CORP 17 June 1974 [28 June 1973] 26661/74 Heading F2U [Also in Division G2] A cassette has a supply reel and a take-up reel, each mounted on a hub, the hubs having interface means accessible from the exterior of the cassette housing so as to be releasably engageable with exterior drive means, each hub having a radially extending abutment member forming a drive shoulder, the shoulders being such that one hub can be driven in a clockwise and the other in an anticlockwise direction. The cassette 10 is of the type in which the film can be exposed, developed and projected in situ. During these various modes of operation the film is wound from spool 14 to spool 20, back again, and so on. As shown, the spool hubs 18 and 24 each have a pair of abutment members 40, 42, extending radially from diametrically opposite sides of the hub. The cassette is inserted into a slot 11 in an external drive system 50. This has a pair of driving heads 60, 70 mounted on shafts 65, 75, which are slidably mounted in frame members 51, 52 so that the heads can be moved into or out of engagement with the hubs 18, 24. As seen in Fig. 3, the heads 60, 70 each have a pair of abutments 62, 72 which are compatible with the abutments 40, 42 on the hubs. Abutments 62 have a drive shoulder 63 and a camming shoulder 64, and abutments 72 are similarly shaped. The hub abutments are also correspondingly shaped, as seen in Figs. (not shown) 4 and 5. Thus although the heads may be randomly oriented with respect to the hubs, as they engage they move round into positive driving engagement. The respective drive shoulders 63 and 73 face so that head 60 drives spool 14 clockwise and head 70 drives spool 24 anticlockwise. The shafts 65, 75 are driven from respective pinions 54, 55 secured to their rear ends. A main drive gear 56 is slidably mounted on a bracket, so that it can be shifted laterally to engage with either of the pinions 54, 55.
