Filed: 1969-04-28
Abstract: 1,272,082. Photographic cameras. AGFA GEVAERT A.G. April 28, 1969 [May 3, 1968], No.21438/69. Heading G2A. A photographic camera has a knob 3 movable between an inner, operative position as shown in which it can engage a film reel or cassette, and an outer, inoperative position, the knob being releasably coupled to a rapid wind lever via a gear-wheel 5 and being coupled to a locking mechanism 10 of the camera back 6 so that the knob 3 is allowed to move to its outer, inoperative position, when the locking mechanism 10 is operated and remains in this position when the camera back is closed. Operation of the locking mechanism 10 in the direction of the arrow 15 causes a profiled portion (10a) Fig. 2 (not shown) to engage one end 9a of an angled lever 9 which thus rotates about a spindle 14 to free its other end from engagement with a groove 3b of knob 3. The knob 3 is now free to move under the action of spring 7 in the direction of arrow 8. The lock slider 10 is yoked by a spring 12 to a slider 13 which carries a locking pin 13b which engages a resilient lug of the camera back 6 in the locked position, the pin being moved as far as the aperture 6b in the unlocking process to free the camera back. The back may be relocked moving slider 13 but without moving lock slider 10, leaving knob 3 in the inoperative position. Pressing of knob 3 in a direction opposite to the arrow 8 enables the spindle 4 to engage a film reel or cassette and is held in the operative position by the angled lever 9 dropping into the groove 3b. In a modification, Figs. 3 to 5 (not shown) the locking pin 13b is provided on a resilient arm (10c) of the lock slider 10.

IPC: F04C28/14
Filed: 1929-07-12
Abstract: 336,295. Eyston, G. E. T. July 12, 1929. Fixed - abutment type; valve-gear and valve-actuating mechanism; compensating for irregularity of flow; governing and regulating. - In a supercharging installation for internalcombustion, preferably aircraft, engines, the pressure throughout the delivery system is maintained constant by controlling the pressure of air delivered by a rotary compressor a which supplies a carburettor chamber c<2>. A sliding valve m operated through a pinion and rack mechanism n, moves to vary the number of holes g covered, in the casing. When moved right back the top casing arc covered is less than the circumferential pitch of the vanes f and no compression takes place. A valve o controls the pressure in the chamber c<2> and may lead the air released from c<2> back to the compressor. U gauges or other means are used to indicate the pressure differences existing between the chamber c<2> and, on one hand, the compressed delivery pressure, and on the other hand, the pressure of the atmosphere. An electric circuit 3 is closed when a maximum permissable pressure in the chamber c<2> is reached and operates warning means such as short-circuiting the engine sparking-plugs. The controls of the valves m and o may be interconnected. Fig. 3 illustrates a modification in which two spring-loaded valves 10 bypass air from the compressor into a box 7 when a control valve 9 is open to the delivery. An alternative means of control consists in providing a hinged cover to part of the compressor casing which opens either inside or outside the delivery channel. The cover may be hinged in two parts. Specifications 313,417 and 326,172 are referred to.

Abstract: 1,140,436. Valves. ROBERTSHAW CONTROLS CO. 9 May, 1967 [8 June, 1966], No. 21562/67. Heading F2V. [Also in Divisions D1 and F1] A pneumatic actuator comprises a housing 21, 22 containing a diaphragm 26 fixed to an output rod 30 and being selectively movable to a plurality of predetermined positions by connecting the chamber 27 on one side of the diaphragm 26 to a source of vacuum 62 by way of a selected one of several passages 75A, 75C ... which is closed to cut off the vacuum when the diaphragm has moved to its selected position. The passages 75A, 75C ... are in the form of longitudinally extending grooves disposed around the periphery of a tubular portion 51 of an adapter 47 which closes the chamber 27, the grooves being covered by a resilient tubular sealing member 48. Each groove is in two parts separated by a ball 74 positioned in a hole and normally urged radially outwardly by a movable member 64 to distort the sealing member 48 and provide open communication between the two groove parts. When a passage is connected to the vacuum source 62 by operation of a selector valve 60 and/or programming means 63, air is withdrawn from the chamber 27 through the selected passage until the ball 74 therein enters a respective cam slot 71A, 71C ... on the movable member 64 and the resilient sealing member 48 is allowed to close the passage whereby the diaphragm remains in position due to the balancing forces of a spring 40 and the pressure differential across the diaphragm.

Abstract: 1315873 Frequency modulation systems SIEMENS AG 19 April 1971 [24 Feb 1970] 21665/71 Heading H4P A plurality of code elements having a discontinuous modulation function have each element subjected to a further modulation before transmission and at the receiver compression is carried out both on the additional and discontinuous modulation functions. The additional modulation may be a function of the frequency. Received signals are applied to pulse compression filters PFI, PFII followed by demodulators DI, DII: the outputs are fed through a subtracting device S feeding a delay element VG designed as a delay line or a shift register provided with a series of tappings into monitoring circuits USI, USII. Due to the delay in VG the outputs on the tappings are available simultaneously. A switch control unit SU controlled by a code generator SC distributes values + 1, - 1 such distribution being controlled according to generator SC so that all the outputs are of like sign which are added in AN as an output D with a stage SAG being set at a threshold level. If an incorrect signal is received at A, in the example given there would not be seven identical amplitudes fed into AN i.e. an incorrect character would result in - 1 instead of + 1 thus reducing the output of AN by two units hence output D does not reach the value set by thres - hold circuit SAG. A seven unit character is illustrated in Fig. 2a the broken lines rising towards the right indicating that frequency of each element rises with passage of time (+1) and conversely in a falling direction (-1). Pulse compression filter PFI is arranged so that frequencies with a rising f.m. function are dealt with compressively and with a falling f.m. function, dispersively, and it is known to employ devices which produce a frequency dependent delay in signals. Pulse compression filter PFII has an f.m. function inverse to that of PFI with a clearly defined maxima occurring with a falling function (- 1) and only a small secondary maxima with rising f.m. (+1) this being described more fully with relation to Figs. 2b, 2c (not shown). The additional modulation may be frequency keyed or phase shift. As the correctness of the incoming signals is monitored by the coding sequence in SC the arrangement may be applied to a "secure" system or may be utilized in "friend or foe" systems employing secondary radars.

Abstract: 1468616 Cycle gear-change operating mechanism J W WECHSLER 21 May 1975 [17 June 1974] 21813/75 Heading B7E [Also in Division F2] A single continuous cable actuates derailleur means at front and rear sprocket clusters of a bicycle transmission. A control unit suitable for attachment to the handlebar pillar comprises a drum 33, Fig. 3, receiving the cable and rotatable by a ratchet wheel 44. When a lever 34 is operated in the anticlockwise sense it moves a push bar 36 to deflect a pawl 38 about a pivot 39 on an arm 40 so that a projection 42 engages an indentation 43 in the ratchet wheel and a portion 48 lifts an indexing pin 46 out of an indentation in the ratchet wheel. Continued movement of the lever turns the ratchet wheel and drum until the pin 46 drops into the next indentation 43, whereupon it is necessary for the lever to be released so that a spring 49 may reset the mechanism in readiness for a further operation. Rotation of the ratchet wheel and drum in the opposite sense is similarly effected by a lever 35. The levers 34, 35 may be connected by cables (not shown) to hand levers mounted at the handlebar grips. The cable, which carries a marker (not shown) movable along a scale marked on the bicycle frame to enable the selected ratio to be identified, passes through two stations at which it operates, respectively, a chain guide 59, Fig. 5, associated with the front sprocket cluster 24, 25, and a chain guide 89, Fig. 9, associated with a five sprocket rear cluster (not shown) and including the usual two jockey sprockets 91. The cable has enlargements 31, Fig. 5, so spaced that each time it is moved one increment as determined by the indexing pin 46 it causes a 90 degree rotation of an assembly consisting of plates 58 fixed to a cam cylinder 50 whereby, due to the engagement of a follower 60 with a groove 51, the chain is shifted from one sprocket to the other. The spacing between other enlargements 32, Fig. 9, on the cable is twice that between the enlargements 31 so that a cylinder 71 with a cam groove 72 engaged by a follower 90 on the guide 89 is actuated only during alternate increments of movement of the cable in one direction. Thus, the shift from low ratio to second involves only the shifting of the chain from the sprocket 25 to the sprocket 24; from second to third involves the shifting of the chain from 24 back to 25 together with a shift from the largest to the second largest sprocket at the rear wheel; from third to fourth involves only the shift from 25 to 24 and so on.
