Title: Improvements in or relating to hydraulic power lifting systems
IPC: B62D49/02
Filed: 1968-06-26
Abstract: 1,236,797. Tractor power lift mechanisms. ROBERT BOSCH G.m.b.H. 26 June, 1968 [1 July, 1967], No. 30371/68. Heading A1P. A hydraulic power lifting system for tractors towing implements via a threepoint hitch linkage includes a regulating control apparatus 23 for initiating raising and lowering of the towed implement and a pressure control device 26 for controlling the pressure in the ram 16, 17 to a predetermined nominal value. The driver operates pre-control slide 35 to block line 34 and connect control passage 37, leading to main control slide 38, to return flow line 36, the control slide 38 then being actuated by a spring to disconnect operating line 33 from return line 36. A first control line 41, provided in pressure control device 26 is connected to the ram 16, 17 via operating line 33 and throttle 40, the throttle 40 being opened fully so that the same pressure prevails in line 41 and ram 16, 17. Hydraulic fluid is then pumped from a reservoir 18 to a pressure line 31 provided in pressure control device 26 via passages 21, 24, 30, and from pressure line 31 to ram 16, 17 via operating line 33 and one-way valve 32, the implement then being lifted accordingly. If the pressure in the ram 16, 17 exceeds the predetermined nominal value, pressure fluid in first control line 41 actuates a sensor 45, in the form of a plunger 48, causing the plunger 48 to lift off its seat 44<SP>1</SP> and connect control 41 to return line 36 via a chamber 43 and passages 59, 58. At the same time, plunger 48 causes pre-control slide 50 to raise against the action of spring 53, the loading of which is adjustable by a screw 54 which sets the predetermined nominal value. Raising of slide 50 connects chambers 56 and 57 and blocks off the chamber 57 from the return line 36. Fluid pumped to pressure line 31 then passes from line 60 and chamber 56 to a chamber 64 of a spring-loaded control slide 66 via chamber 57 and a line 62, thus pushing control slide 66 down against the action of a spring 67 so that pressure line 31 is connected to return line 36 via transverse bores 70 in slide 66, bore 69 in slide 66 and passages 59, 58. Fluid supply to ram 16, 17 is then stopped until the pressure in the ram has reached predetermined value when plunger 48 again seats against its seat 44<SP>1</SP>. If the regulating control apparatus 23 is used to control tractive forces and position of the towed implement, a maximum pressure (for opening sensor 45) in excess of the predetermined nominal pressure is set by screw 54. The pressure control device 26 then acts as a safety valve for the regulating control apparatus 23.

As shown the clip is used with other similar clips for securing a metal beading 28 to a car body so as to hide the joint between the rear window and the panel 22. The glass window 23 is surrounded by a rubber sealing strip 24 which has a U-shaped groove 25 to receive the glass and a flange 26 which overlies the edge of the opening on the outside face of the panel 22 and a portion 27 which partially overlies the flange 26. The fastening device is a selftapping screw 29 which passes through the apertures in the two plates into a hole in the panel. The flange on the underplate is passed between the lip portion 27 and the flange 26, which prevents rotation of the plate, and the beading is engaged with the limbs 18, 19 of the overplate. The overplate is prevented from rotation by a pair of dimples 13, 14 on the underplate. A small amount of movement at the overplate is possible since the screw aperture 17 on the overplate is elongated.

Title: Indicating Means in Photographic Cameras
IPC: G03B15/04
Filed: 1966-07-07
Abstract: 1,154,354. Photographic cameras. EASTMAN KODAK CO. July 7, 1966 [July 12, 1965], No.30545/66. Heading G2A. A photographic camera having a socket for receiving flash-cubes and indexing means associated therewith for rotating the socket, is further provided with means for indicating that a predetermined number of flash-bulbs in an inserted cube have been fired. In the embodiment shown, insertion of a flash-cube into the socket (not shown) depresses a pin 16 until lobes 17 thereon enter a pair of control spaces 18a of a cam 18 normally spring urged so that a lug 20 thereof engages a stop 21 on a locking member 22. As the cube, socket and pin are rotated through 360 degrees to fire all the lamps the lobes 17 engage a pair of lugs 18b and rotate the cam 18 anticlockwise (as seen) against the spring bias. As the full rotation is being completed, the lug 20 engages the member 22 and displaces it to the left, thereby moving a portion of the member 22 into the path of movement of a trigger 25, thus preventing further shutter release. This indicates to the camera user that all the flash-bulbs in the cube have been used. As the spent cube is removed, the pin 16 moves upwards to free the lobes 17, thus allowing the cam 18 and the member 22 to return to the positions shown under spring action. In another embodiment Figs. 1, 2 (not shown) a sector gear (1) is rotated clockwise by a pinion gear (4) which in turn is rotated with an inserted flashcube. As the cube is indexed for the fourth time, the gear (1) pivots a lever (6) into the path of the shutter release trigger, preventing further exposures until the cube is removed, when the lever (6), and hence the gears (1), (4) are spring urged back to the positions shown. In a further embodiment Figs. 7 to 10 (not shown) the indicating means comprises means for blocking the film winding mechanism. If desired, the blocking means may be manually set to come into operation after less than four lamps have been fired. Alternatively or additionally there is provided a visible counting mechanism Figs. 11, 12 (not shown). Insertion of a flash-cube in the socket connects gearwheels (62), (64) so that rotation of gear (62), as the socket is indexed, is transmitted to a signal wheel (63) bearing five symbols, one of which is visible in the camera view-finder. Rotation of the wheel (63) changes the symbol visible.

Filed: 1925-12-03
Abstract: 267,199. Siemens Bros. & Co., Ltd., and Goodwin, W. E. Dec. 3, 1925. Mechanical interrupters; timing devices; contacts.-In a telephone exchange circuit-interrupter in which the make-to-break ratios of the spring contacts is variable, the stationary spring is stressed to follow up the movement of the movable spring to separate the contacts and is limited in such motion by an adjustable stop. As shown in Fig. 1, the spring 2 is oscillated by a cam 9 on a rotating shaft 10 to make and break contact with a relatively stationary spring 1. This spring is strained so that it follows up the spring 2 until its end is arrested by the head 7 of an adjustable stop. Where face cams 14 are employed as shown in Fig. 3, the stop 13 may pass through a suitable aperture in the movable spring 12 to engage the spring 11. Where a number of sets of contacts are spaced around the shaft 15 as shown by springs 12, 19 in Fig. 4, to produce interruptions at different time intervals, the stops may form a means for fine adjustment of such intervals. A slight time interval between interruptions may be effected by the movable spring of one set acting on that of another set after moving a prescribed distance. The adjustable stops are arranged adjacent to the contacts.
