Title: Improvements in or relating to automatic exposure control apparatus for photographiccameras
IPC: G03B7/12
Filed: 1960-06-23
Abstract: 903,528. Photo-electric exposure control. KABUSHIKI KAISHA KOPARU KOKI SEISAKUSHO. June 23, 1960 [June 24, 1959], No. 22035/60. Class 40 (3). [Also in Group XX] In a camera in which the aperture is set automatically in dependence upon an exposure meter and a manually set exposure time, if the correct exposure is not possible even with the smallest aperture, the exposure time is automatically shortened. The camera is coked by mechanism (not shown) rotating a ring 29, Fig. 8, carrying lugs 29d-29h, Fig. 2, anticlockwise to the position shown in Fig. 2. Actuation of the release 5 permits ring 29 to run down under the action of a spring 44 and a governor G. Lug 29h permits the exposure time control cam 12 to rotate clockwise until a lug 15a on a plate 15 contacts the lug 24a. The relative position of cam 12 and plate 15 is controlled by the exposure time setting lever 7, a toothed segment on which meshes with a cog 14, Fig. 3, of a differential gear 13, 14, 17, 18. Cam 12 thus sets the exposure time governor S via the lever 10. During this setting, the shaft 16 rotates a drum 30 through a collar 32 and a differential gear 42, 37, 39, 40. As lugs 15a and 24a connect a pin 15b releases, via a lever 23, an aperture setting cam 20 which rotates drum 30 through the same differential gear until drum 30 contacts the pointer 31 of an exposure meter L. Cam 20 arrests the aperture setting member 25. If cam 20 rotates to the minimum aperture position before drum 30 contacts pointer 31, a pin 21b actuates the lever 24 to release lug 15a which allows the exposure time to be adjusted through the differential gear 42, 37, 39, 40 until drum 30 contacts pointer 31. Finally, lug 29d contacts a lever 4 to operate the shutter.

Title: Improvements in transistor circuit arrangements
IPC: H03F1/30
Filed: 1959-07-06
Abstract: 867,954. Transistor amplifier circuits. REGULATOR A.G. July 6, 1959 [July 8, 1958], No. 23138/59. Class 40(6) An emitter follower transistor amplifier has in its emitter circuit a thermistor operated at the peak of its current voltage characteristic or on the downwardly sloping region of the characteristic so as to stabilize the emitter collector voltage. Fig. 4 shows an emitter follower stage directly coupled to a common emitter stage. A thermistor connected in the emitter circuit of the first transistor is operated on the part of the characteristic where the voltage developed across it is approximately independent of the current passing through it or where the voltage decreases slightly with increasing current. Thus, changes in current through the transistor due to changes in the transistor characteristic or replacement of the transistor do not vary the voltage across the thermistor and accordingly do not vary the proportion of the input voltage developed across the transistor. Changes in ambient temperature of the circuit also cause changes in the current through the thermistor so as to maintain the collector emitter voltage more constant.

Title: Improvements in brake mechanism for motorcars and other vehicles
IPC: B60T11/06
Filed: 1924-09-20
Abstract: 238,722. Rover Co., Ltd., and Poppe, P. A. Sept. 20, 1924. Hand and foot actuation; force-transmitting mechanism; compensating for wear.-Brake operating mechanism for vehicles comprises transverse shafts geared together by toothed gearing disposed in the central plane of the vehicle certain or all of which carry arms connected to the brakes such arms being arranged equidistant from and at opposite sides of the gearing. Skew-gearing with free axial movement may be used to give an equalizing compensating action or one such gear may be axially adjustable by hand to compensate for wear. According tc one arrangement, three transverse shafts e, f, g are provided geared together by skew-gear pinions e<1>, f<1>, g<1> splined thereon respectively, the middle shaft f being in two parts, and the pinions being disposed in a fixed casing j. The pedal d is connected by an arm e<2> to the shaft e and arms f<2>, g<2> on the shafts f, g are connected by rods n, o, n<1> to the front and rear brakes respectively. The pinions e<1>, f<1>, g' are disposed centrally midway between the arms f<2>, g2 whereby torsional stresses on the shafts is reduced. Application of the brakes may also be effected by an upward pull on a member c connected by arms r, q and a compression link p to an arm g<3> on the shaft g. The link p is telescopic to prevent interference of the hand control connections with the pedal operation. Locking means for the hand-control member c comprises a rack on the member for engagement by a pin c<2> on a sleeve c<3> sliding in a casing c<1> and urged to engaged position by a spring c<4>. A spring plunger c<6> sliding within the sleeve c<3> abuts on the back of the member c. A hand lever of the usual type may replace the member c. The shafts f, g may be given an angular adjustment relatively to the shaft e to compensate for wear in the brakes by sliding the pinion e' laterally on the shaft e. For this purpoee the pinion may abut against a sleeve j<3>, Fig. 8, which can be screwed into the casing j by worm gearing j<4> actuated by a shaft j<5>. One of the pinions say f<1> may instead be arranged to move axially to a limited extent to provide an automatic equalizing or compensating action. The shaft e may be dispensed with and the pedal be connected to the shaft f. The mechanism may be adapted for operating two pairs of rear wheel brakes either by duplicating the arms g<2> or by reversing the arms f<2> and connecting them to the additional rear brakes or if the front wheel brakes are retained either of the arrangements just described for the additional pair of rear brakes may be used and an additional shaft be added, if necessary, for the front brakes.

Title: Improvements in rotary printing machines
IPC: B41F13/02
Filed: 1958-07-11
Abstract: 869,903. Printing-machines; inking apparatusÀ TIMSON, E. A. July 1, 1959 [July 11, 1958], No. 22313/58. Class 100(2) A rotary printing machine of the kind comprising rotary printing couples between which a web is printed and a drying zone having heating devices through which the web passes after printing has means, interlinked with mechanism for terminating printing on the web, which is automatically actuated at a predetermined speed of the machine during stopping. As shown, a web W is passed through a drying chamber 3 after printing at a station P. A plate cylinder 1 is mounted in stationary bearings, while an impression cylinder 2 has a shaft 13 mounted in eccentric bearings 12. The bearings 12 are rocked by arms 14 actuated by a piston 23 in a cylinder 22 supplied with air under pressure through a solenoid-operated valve 21. An electric motor 6 for driving the printing couple has a speed control mechanism 15. A timing device 16, synchronized with the mechanism, controls an electric switch 19 in the circuit of the .solenoid 20 operating the valve 21. In operation, the impression cylinder is tripped until the machine attains a predetermined speed and is tripped again during stopping when the predetermined speed is attained, thereby obviating ignition, in the drying chamber 3, of ink solvent which would burn the printed web. The heating devices 4, 5 are rendered inoperative immediately prior to, or simultaneously with the termination of printing. An inking 24 is tripped in the manner described in Specification 869,904. Specification 22312/58 also is referred to.

Abstract: 1459474 Endoprosthetic joint SULZER BROS Ltd 20 May 1974 [19 July 1973] 22395/ 74 Heading A5R [Also in Division E2] A hinging metacarpophalangeal joint comprises first and second parts each having an intramedullary stem, the first part 1 being mounted in a slot 6 in the second part 7 so as to be hingable relative to second part approximately through a right angle between end positions corresponding to the bent and extended conditions of the joint about a pivot pin 9 secured in the second part, the axes of the intralmedullary stems of the first and second parts defining in the bent condition of the joint a plane of hinging substantially perpendicular to the axis of hinging, the slot and the first part being shaped so that in the extended condition of the joint there is a clearance between one side of the slot and the first part to permit the first part to pivot about an axis transverse to the axis of hinging whereby the axis of the stem of the first part can pivot out of the plane of hinging substantially to one side of the plane of hinging only, while in the bent condition of the joint there is a reduced clearance between the side 13 of the slot and the first part whereby movement of the axis of the first part out of the plane of hinging is substantially prevented. The side walls 13, 14 of slot 6 may diverge from one another, the sides of part 1 being parallel or the walls 13, 14 may be parallel, the sides of part 1 being recessed and non-parallel to allow the required lateral movement. Part 1 is a loose fit on pin 9 to allow such movement. Slot 6 is closed at the top by a member 15 which prevents overstretching of the fingers. The extent of lateral movement of the part 1 is limited by contact of the surface 16 with surface 13. As the finger is bent the possibility of lateral movement becomes increasingly restricted since contact between the surfaces 16 and 13 is made at increasingly smaller angular displacements of part 1 from the plane of hinging as the joint is bent.

Title: Process and apparatus to wind thread continuously on a succession of reels
IPC: B65H67/052
Filed: 1976-06-01
Abstract: 1519413 Continuous thread winding apparatus ETUDES ET FABRICATIONS 1 June 1976 [29 May 1975] 22548/76 Heading D1J A continuous thread winding apparatus of the kind in which the thread 6 has to be transferred from a full reel 3 to an empty reel 4 that is parallel with the full reel comprises a first catch pin 26 near the empty reel 4 that can be moved to a setting where it engages the thread 6 as it is being transferred and guides it onto a cutting device 52 and into a coupling relationship with the empty reel 4; and a second catch pin 27 near the full reel 3 that can be moved to a setting where it maintains the cut thread now extending from the full reel 3 parallel to an end flange 49 of the full reel, there being means to control the positioning of the catch pins in the correct sequence when a reel has been fully wound. The pins 26, 27 are identical but in the interests of clarity only one of the pins, namely pin 27, is shown in Fig. 3. It comprises a straight arm 27a and a curved arm 27b that jointly define a notch that is capable of receiving the thread 6. The pins 26, 27 are both mounted on a plate 8 that can be swung down into an inoperative setting indicated by broken lines, the movement of the plate 8 being controlled by a piston and cylinder unit 12 to 15. When the plate 8 is swung up into its operative setting, shown in full lines, both pins 26, 27 will be in the setting shown at 27c, such a setting serving to guide the thread 6 along a line that is parallel with the flanges 49, 51 of the two reels. However, as shown in Fig. 2, pin 26 has been retracted to a setting in which it has pulled the thread 6 back against an annulus 2 rotating with the empty reel 4 so that the thread is snagged and commences to be wound onto the empty reel 4. This rearward movement of the pin 26 has been controlled by electro-magnetic means 31, Fig. 3, that can swing either of the two pins 26, 27 back into the position shown in full lines. The apparatus also includes a pair of protective covers 19, 20 that can each move in a direction parallel with the axes of the reels 3, 4. As shown in Fig. 2 the cover 19 has moved to a setting in which the thread 6 has entered a slot 21 in the cover 19, the cover then preventing the thread from causing damage as the cut thread extending between the two reels is wound back onto reel 3. Cover 20, on the other hand, has been moved to a setting in which a cutting edge 52 forming part of the cover 20 is presented to the thread 6 to cut it. The apparatus includes thread traversing means and associated control means such that when a reel is full and thread 6 has to be transferred from one reel to the other, the thread traversing means moves the thread towards the end flanges 49, 51 to hold it there while the above described means transfers the thread 6 from one reel to the other.
