Patent GB-130603-A (GB)
IPC: G03B27/08
Abstract: 130,603. Kelley, W. van D., and Mason, J. Ju]y 26, 1917, [Conventiondate]. Kinematographapparatus.-In a method and apparatus for printing kinematograph films and more particularly for printing colour films on to a single positive film, and to allow for shrinkage in developing the negative films, registering pins are used to register the negative with the positive film as standard, one pin filling corresponding perforations in the negative and positive films, from side to side, to take up lateral shrinkage, and another pin filling corresponding- perforations from top to bottom to take up longitudinal shrinkage. In the apparatus shown, registering pins are fitted on each side of the exposure gate and engage the sprocket holes of the negative and positive, before each exposure, one of the pins 18, Fig. 6, filling the perforations, longitudinally, and the other pin 17 substantially filling the perforations. The apparatus is more particularly for printing from negatives having recurring series of colour components from. which each colour series is printed in super position on the positive. The pins 17, 18 are carried by a. presser plate 11, sliding on fixed rods 14, Figs. 1 and 4, and pressed towards the gate by springs 16. The plate and pins are retracted synchronously with the intermittent feed of the film by rods 41 which are reciprocated by a cam disk 27 and linkwork 31, 38, 40. The slotted link 31 also controls the to-and-fro motion of the feed pins 26, the up-and-down feed motion being obtained by the cam disk 23 and slide 24. For a two-colour negative, the negative 3 is stepped twice for each feed of the positive 4 by forming separate cam surfaces 28, 29 on the wheel 27 of suitable height and whereby on alternate feed motions the feed pins 26 are stopped short of the positive film 4, and the plate 11 is not permitted to move far enough for the registering pins 17 and 18 to operate. The negative and positive films 3, 4 pass through separate guideways 5, 6. A shutter 44 rotates synchronously with the film movement. Where a positive film is printed on opposite the negative also has to be reversed and the pins 17, 18 are interchanged so that they operate on the same sides of the films in both printings. The period of exposure is determined by the aperture in the shutter which can be adjusted according to the character of the positive emulsion, so as to obtain quick exposures on a slow emulsion and thereby prevent fogging of one side of a doubly coated positive by exposure of the other side. The cylindrical enclosure 46 may be fitted with a condenser or lens for obtaining a parallel printing beam. The Specification as open to inspection under Sect. 91 (3) (a) includes also the use of a doublecoated positive film without an opaque coating between, sensitized with a slow emulsion and printed with a sufficiently intense light. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to lifting and tipping device for dust-bins and the like
IPC: B65F3/04
Filed: 1957-04-24
Abstract: 829,587. Tipping dustbins. ZOLLER, H. April 24, 1957 [May 4, 1956], No. 13102/57. Class 78 (4). A carriage 28 carrying a dustbin 36 is first raised in guides 22 by a ram 24 and then the guides are turned about a pivot 16 to tip the bin 36 into a refuse vehicle 1 by a ram 12. The rams 24, 12 are connected to the same fluid pressure system but the sizes of the pistons and the leverage of the rams is such that the ram 12 is not extended until a stop 35 on the carriage comes into engagement with a stop 39 on the guides. The leverage of the ram 12 is increased towards the end of the lifting motion when a roller 29 on the carriage engages a guide 10 to effect an initial tipping of the guide 22. In the construction illustrated, the rams 24, 12 are connected to the back pressure set up by a manually controlled valve in a circulating system, and a choke by-passed by a non-return valve in the supply to the ram 12 damps the ram as the bin returns from its inverted position. The ram 12 is fed through its hollow piston-rod. As the bin 36 is swung into the chamber 1 it pushes a plate 2 about an axle 4, which may, however, be coincident with the axle 16, and a closure 3 on the plate 2 may open the lid of the bin in the usual way. The plate 2 is locked against inward turning movement by a spring- biased pawl 15 until an arm 17 coupled to the pawl is engaged by a pin (not shown) on the guides 22 as they tip. The pin rests against a sponge rubber facing on a bearing plate 33 carried by a resilient metal member 32 from the carriage 28.

Title: Decoding apparatus
IPC: H04L23/00
Filed: 1975-03-27
Abstract: 1508653 Decoding apparatus WESTERN ELECTRIC CO Inc 27 March 1975 [28 March 1974] 13115/75 Heading G4A Variable length prefix code words are decoded by dividing them into fixed length sequences which are used to address memories holding translation tables. As described a K bit register 211 (Fig. 2) (K< L) is used. The K bit word, incremented by one is used to access a primary table memory 214. If the word corresponds to a code word of length less than or equal to K its code length is fed from register 216 to shift the input register 210 and the code word is fed to a utilization device. If however it only represents part of a code word the address of a table in secondary table memory 250 and the length of the code word minus K are read out from the primary memory 214. The next K bit word is fed to register 211, part of the word being used under the control of decoder 260 (fed with the read out length) together with the address to access the table in secondary memory 250 to derive the required code and its length. The former is read to the utilization device and the latter is used to shift the input register. When the code word is of length greater than K a bi-stable 285 prevents the read out of the contents of the primary table to the utilisation device and to the shift control of the input register.

Abstract: 1,235,273. Change-speed control. HONDA GIKEN KOGYO K.K. 12 March, 1969 [13 March, 1968], No. 13127/69. Heading F2D. In an automatic change-speed vehicle transmission (not shown) controlled by oil pressure engaged second and third (top) speed clutches 1, 21 &c. (first (low) speed not shown or described), the rate of increase in pressure during engagement of either clutch 1 or 21 is controlled by a valve 8 or 23 respectively to effect a rapid initial pressure rise to take up clutch play &c., the rate of increase then being decreased to cushion clutch engagement and then gradually increased to effect full clutch engagement (Fig. 2, not shown). The valves 8, 23 are connected to a pressure source 2 (i.e. pump) via spring- loaded 1-2 and 2-3 shift valves 20, 22 responsive to engine load (TV pressure) 18, acting to augment the spring loads, opposed by output governor speed pressure 19 such that for establishment of second speed the output governor pressure overrides the TV pressure &c. to move the valve 20 rightwards to connect valve 8 via duct 3 to the pump source 2 and pressurize and engage the second speed clutch 1, further speed increase subsequently also moving the valve 22 rightwards to exhaust clutch 1 and pressurize and engage third (top) speed clutch 21, the valves 20, 22 having differential loads of differing sizes (one valve to the other) at their left-hand ends (i.e. the ends acted on by the output governor pressure) whereby the valves 20 and 22 are moved in the above order. The control valves 8, 23 each comprise two spools 7, 9 of different diameters spring urged apart to seat at their outer ends whereby the valve spool 7 fully opens the feed duct 4 to the duct 5 of the connected clutch 1, 21, the ends of the spools 7, 9 being additionally connected via ducts 13, 14 respectively to the duct 5, the latter duct 14 incorporating a restrictor 17 therein. When, during second and third shift intervals, the shift valves 20, 22 operate to connect either control valve 8 or 23 to the pressure source 2 the rate of pressure increase in the appropriate clutch 1 or 21 is initially rapid to take up clutch play at which point the corresponding pressure build up in the duct 13 acting on end 15 of spool 7 temporarily moves the spool 7 towards its closed position to decrease the rate of supply pressure to cushion clutch engagement, the restrictor 17 delaying the pressure rise at the end 16 of the larger spool 9 such that it slowly moves to return the spool 7 to its fully open position for completion of clutch engagement.

Abstract: 473,771. Master control of motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. (Metropolitan-Vickers Electrical Export Co., Ltd.) May 12, 1936, No. 13460. [Class 38 (iii)] [Also in Group XXXVIII] In a signalling system for mine hoists of the type in which signals are interchanged between the driver and the banksman and between the driver and the onsetter by means of a prearranged code of audible and/or visible signals, the operation of the hoist is permitted only in the event of a correct interchange of signals. Figs. 1 and 2 show a control system for a Ward-Leonard system of control for the hoist, the generator field EXF being closed to permit operation by the driver only when relay SC is operated in response to the correct signals. The circuit of relay SC includes contacts OP1, B1S1 which are opened when the driver's control lever is in the " on " position and the hoist brake is " off " and are short-circuited to facilitate control of the hoist by the contact MSCa of a relay MSC, which is operated in response to the correct interchange of signals. The driver and banksman are provided with signalling keys DP1, BP respectively, operation of either key causing operation of bells B1, B2 and a stepping relay 1R1 of a selector mechanism 1R1 (2, 3 .....). The driver and onsetter also are provided with keys DP2, OP for operating bells B3, B4 and the stepping relay 1R2 of a selector 1R2 (1, 3, 4.....). The contacts of the selectors are arranged in circuit with the relay MSC in such a manner that the relay is pulled up only in response to prearranged codes of impulses between the driver and the banksman and onsetter. The driving gear is then placed under the full control of the driver. When the brakes are applied near the end of the wind, contacts B1S2 are closed and relay MRR is operated to restore the selectors to normal and thus deprive the driver from taking over further control until a further correct interchange of signals is effected. Resetting of the apparatus during winding may be effected by a reset key DRK or by further operation of the keys DP1, DP2, BP, OP. In the modified resetting equipment shown in Fig. 3, resetting is effected in response to the driver's " all-clear signal, viz : three rings, at the end of the wind indicating that it is safe for men to alight. During the wind, relay CC is operated at " brake-release " contacts B1S3 and at the end of the wind is maintained operated over contacts CCa. Contacts 1R1a or 1R2a are operated by the three " all clear " impulses and magnet CNC steps a switch RA which at its third step operates relay MRR which energizes the resetting relays RC1, RC2, RC3, and releases relay CC. A key DRK is provided for emergency purposes and a contact PC is operated to effect resetting when a control lever, provided for adapting the system to the winding of " men " or " material," is operated. Contacts MS1e also are closed or opened according to whether the system is controlling the winding of men or material.
