Title: Improvements relating to means for controlling the automatic guidance of double axles on motor vehicles when travelling around curves
IPC: B62D13/00
Filed: 1960-02-04
Abstract: 885,615. Stabilized steering for road vehicles. DAIMLER-BENZ A.G. Feb. 4, 1960 [Feb. 4, 1959], No. 4014/60. Class 108(2). Movements of motor vehicle double axles 10, 11 carried on thrust links 12, 13 pivoted, at 14 and 15, to the vehicle frame 19 to guide up and down movements of the axles and to permit them to have balanced, mutually contrary swinging movements when travelling around curves are controlled by a spring element 18 which operates between at least one of the axles and the frame to resist the swinging movements and by manually or automatically controlled holding means 28 between an axle and the frame additionally to resist and prevent the swing- ing movements when desirable. The axles are connected by longitudinal leaf springs 16, 17 which are pivoted to the frame 19 at their mid-length point. The element 18 has an adjustable, prestressed spring 22 mounted between discs 23 loose on a rod 25 and normally supported on seatings 24 in a casing 20. Movement of the discs 23 on the rod 25 is limited by pistons 27 movably supported in the casing 20 so that relative motion between the rod and the casing further compresses the spring 22 to resist swing- ing of the axles. The element 18 may be supplemented or combined with a shock absorber 49. The holding means 28 has a pressure cylinder on the frame 19 in which are opposed pistons 29 and 30 of different diameters. A link 38 is pivoted at 39 to the axle 10 and to a cup 34 in which slides a buffer 33 on the rod of the piston 29. Compressed air admitted by a manual control or automatically on engagement of reverse gear can cause the pistons 29 and 30 to separate whereby a flange 41 on the cup 34 is clamped against a flange 36 on the piston 30 to prevent movement of the axle 10. An alternative spring element 42 shown in Fig. 3 has opposed pistons 43, 44 which are separated against springs 45 when air pressure is admitted at 31 causing rollers 47 at the ends of the piston rods to bear against abutments 48 on the link 12. In an embodiment shown in Fig. 4 a hydraulic cylinder 52 and piston 51 which connect the link 12 to the frame have conduits 53 on either side of the piston leading to cylinders 56, 56<SP>1</SP> and pistons 57, 57<SP>1</SP> connecting the link 13 to the frame. Pressure from the cylinder 52 will cause one or other of the pistons 57, 57<SP>1</SP> to move against the spring 60. Movement of the pistons 57, 57<SP>1</SP> is controlled by air pressure admitted between them through a conduit 61 from a differential piston 63 operating against a spring 64. This pressure normally operates against a spring 64, but it can be intensified so as to lock the pistons by admitting air at 65 against the piston. 63. The embodiment in Fig. 4 has pneumatic spring bellows 50 acting on the links by way of cross-members 66 in place of the longitudinal springs of Fig. 1.

Filed: 1943-03-13
Abstract: 566,765. Impregnating castings. JAMES, H. LESLIE-. March 13, 1943, No. 4108. [Class 140] In the reclamation of unsound or defective hollow metal castings, particularly light alloy non-ferrous castings, by impregnation with a solution of a phenol- or cresol-formaldehyde condensation product, the impregnating solution is forced under pressure into one side of the casting and the other side is evacuated. As shown, the castings 3 are enclosed in a chamber 2 connected at 5 to a vacuum pump and are connected by flexible connections 6, 7 to tubular members 8 fitted with air-tight joints in the wall of the chamber 2. The inner ends of the tubular members 8 may be fitted with a number of nozzles to permit use of a number of pairs of flexible connections. The outer ends of members 8 are connected with supply and return pipes 9, 10 communicating with a container 11 for the impregnating solution, which is forced under pressure to the castings by a pump 4 operated by hand or power. The nature and location of the defects in the castings are ascertained by testing under water with compressed air. The casting is placed in chamber 2 and the cock 13 in return pipe 10 opened, and after circulation of the impregnating solution is closed and the operation of the pump 4 continued to force the solution under pressure into the defective part of the casting. The surplus impregnating solution is returned to the container 11 by opening the valve 15 on the compressed air line 14. The impregnated casting is then removed and heated to cure the resin. A number of similar defective castings may be threaded on to a spindle and clamped together in air-tight manner and treated at one operation.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/64
Filed: 1937-02-13
Abstract: 490,061. Photographic shutters. KODAK, Ltd. Feb. 13, 1937, No. 4328. Convention date, May 12, 1936. [Class 98 (i)] Separate tensioning levers for the shutter and delay action mechanisms, a common release trigger and a locking lever enable the shutter release to be prevented until a part of the delay action mechanism has run down, released the locking lever, and actuated the shutter release. The shutter is set by a member 9 which causes a pin 10 to move in a slot 11 in the master member 12. A latch member retains the latter in set position and is released by movement of a trigger 8, the shutter blades being rocked by a lug as described in Specification 491,885. A trigger lever 23 is pivoted upon a stud 24 carried by the trigger 8, and has formed on one arm, a cam surface 25, a hook 26, and a lug 27. The lug 27 extends downwardly through an opening 28 in the annular plate 29 into the path of a plate 30 attached to the pallet 31 of a gear train 32. A drum 33 in the gear train contains a coil spring and is set in accordance with the time of delay action by an interengaging ring 36 and lever 35. The ring 36 is provided with a cam 39 and hooked end 40. When the master member 12 and the gear train are set and the trigger is operated, the lug 27 drops into a notch 38 in the opening 28 preventing further operation of the trigger. The plate 30 is simultaneously released and the gear train commences to rotate. The hook 40 then slowly engages the cam 25 swinging the lever 23 about its pivot until the lug 27 is free of the notch 38, and the hook 27 is engaged by the hook 40 on the ring 36 and causes complete actuation of the trigger 8 to operate the shutter blades. The hook 40 then slips off the hook 26 and the trigger and other parts return to the initial positions. A latch 42 pivotally mounted on the plate 29 is pressed by a spring 44 so that the hook 45 can engage a notch 46 in the ring 35 when the parts are untensioned. Movement of the setting lever 9 brings a lug 48 on the setting member into engagement with a flange 47 on the lever 42, thereby swinging the locking lever out of position. The shutter may be actuated for normal exposure without operation of the delay action mechanism, since in the unset position of the ring 36, the hook 40 guides the lug 27 away from the notch 38 and allows complete actuation. Specification 462,126 is referred to.
