Title: Improvements in or relating to photographic printing processes
IPC: G03F7/14
Filed: 1929-10-23
Abstract: 341,924. Photographic printing processes. SHEPHERD, F. J., Kilcorrel, Flower Lane, Mill Hill, London, RENWICK, F. F., Rodenside Laboratory, and ILFORD, Ltd., both in Ilford, Essex. Oct. 23, 1929, Nos. 32230/29 and 15835/30. [Class 98 (ii).] " Bromoil " prints are made on supports sensitized with silver-halide gelatine emulsion to which a hardening agent has been added before coating, so that the gelatine has a melting-point above 105‹ F. The developed and bleached print is uniformly inked by a roller or spray device and gradation is developed thereon by rolling its surface with a roller. The support for the emulsion layer may be paper, celluloid, glass, cellulose acetate, or the material known under the Registered Trade Mark " Cellophane." In an example a silver-bromide gelatine emulsion prehardened with chrome alum or formalin is exposed under a negative and developed by a non-tanning developer. The developed print is rinsed and transferred to a stop bath. The latter may comprise a solution of boric acid and is adapted to bring the surface of the print to a uniform hydrogen ion concentration comparable with that of the bleaching bath. The use of borax or sodium acetate for controlling ion concentration is referred to. The print is removed from the stop bath to a bleaching bath, washed, fixed, washed again, and dried. The dry print is then uniformly inked by an inking roller or spray device, damped by immersion in cold water or by rolling with a wet fabric covered roller and treated with a rubber or felt covered roller which removes ink from the softer parts of the gelatine. All the operations are carried out at normal temperatures. The print so obtained may constitute the final print or may be used as a printing surface. Two or more coloured images may be combined to give a colour photograph either by superposition or by transfer to a common support.

Abstract: 858,457. Packing case fittings. METALASTIK Ltd. Oct. 23, 1957 [Oct. 24, 1956], No. 32426/56. Class 18. [Also in Group XXXII] A mounting 12, 13 for carrying delicate equipment 11 in a container 10 is supported on springs 14, and shock absorbers 21 act between the mounting and the container to provide a damping force proportional to the velocity of deflection of the equipment relative to the container. The springs 14 each comprise concentric tubes 18, 19 bonded together by a tapering ring 20 of rubber having a linear loaddeflection characteristic. The hydraulic shock absorbers 21 are such that the energy absorbed is proportional to the relative velocity between the telescopic elements 22, 23. The inner telescopic element 22 is connected by an inwardly tapering rubber mounting 29, Fig. 4, to a bracket 25 secured to the container. The shock absorbers and the springs are matched so that the deflection for a given maximum load is about one half that for a simple spring.

Abstract: 1235497 Electro-photographic charging apparatus RICOH KK 8 July 1968 [6 July 1967] 32450/68 Headings G3R R62 R4 R22Ax and R29 The discharge in a charging device for use in electrostatic reproducing apparatus is stabilized by a feedback arrangement controlled by the discharge current. In the embodiment tungsten discharge and probe electrodes 1, 2 respectively are situated in a recess in the corona screen 3, and the discharge current flows from the discharge electrode 1 to the target 10 via paper 11 which is charged in accordance with the image being reproduced. The current also flows to the probe electrode 2, from where it is fed back into the discharge current generating circuit via a potentiometer 4 and amplifier 5 to stabilize the discharge current supply. As shown the generating circuit comprises an oscillator including a pentode VI, and the feedback signal is applied to the screen grid of the pentode VI to stabilize the amplitude of the oscillations, which are then rectified and smoothed by a circuit 9 and provide the discharge potential on electrode 1. Alternatively the discharge current generator may produce pulses whose pulse repetition rate is stabilized by the output from amplifier 5. The probe electrode 2 may be dispersed with, in which case the variations of potential on the corona screen 3, earthed through a small impedance, are used to effect stabilization.

Title: Improvements in and relating to machines for lapping or polishing machine parts and the like and to methods of using such machines
IPC: B24B33/10
Filed: 1936-11-27
Abstract: 468,923. Grinding cylindrical surfaces. JUNKERS FLUGZEUG - UND-MOTORENWERKE AKT.-GES. Nov. 27, 1936, No. 32530. Convention date, Dec. 7, 1935. [Class 60] In a machine for lapping or polishing cylindrical surfaces comprising a reciprocating and rotating toolcarrying spindle, means are provided which impart to the spindle a rotation in one direction on the outward stroke and in the other direction on the inward stroke and in addition resistances are provided to influence the amplitude of the rotary movements, the resistances operating during the inward and outward strokes being different so that the amount of rotation in the two directions is different. The spindle 10, 12 carrying the tool 18 is mounted in a projecting part 9 of a slide 3 adapted to be reciprocated from a spindle 4 through an adjustable crank 5 and connecting rod 7 so that the spindle is rotatable in, but longitudinally fixed relatively to the slide. The upper part of the spindle is formed with a plurality of fast threads 11 engaging within a threaded bush 25 rotatably mounted in a hub 31 on the machine frame 1 and prevented from axial displacement by flanges 26, 27. A friction washer 30 is inserted between the hub 31 and flange 27 so that the resistance to the rotation of the bush is greater when the spindle is moving downwardly. The spindle will therefore be rotated by the action of the screw threads 11 to a greater extent when moving downwardly than when moving upwardly. The amounts of the rotation of the spindle may be varied by a brake 33 acting on the bush 25 and a brake 41 acting on the spindle. The lower part 12 of the spindle may be adjusted longitudinally of the upper part 10 by means of nuts 13, 15. In a modified form the friction washer is omitted and the lower plain bearing is replaced by a ball bearing. For treating external cylindrical surfaces a ring or other suitably shaped tool would be used.

Title: Improvements in coal wash boxes
IPC: B03B5/24
Filed: 1952-12-27
Abstract: 732,493. Washing coal. BLANTYRE ENGINEERING CO., Ltd., and ROGERSON, H. W. March 19, 1954 [Dec. 27, 1952], No. 32801/52. Class 82 (2). A coal-washing jig has an electrically operated valve 9 which is energized when the water level in tube 10 is sufficiently high to connect electrodes 12 and which opens the entry to an air-lock chamber 6. As a result the pulsations of the water are increased in amplitude and the shale discharge rate increases. When the shale bed has dropped to a normal level the pressure of water under the bed falls and thus the water level in the tube falls to break the circuit to the valve. An orific plate 11 or flapvalve may be fitted at the bottom of tube 10 to dampen the water movement.

Title: Flexible time recorder
IPC: G07C1/00
Filed: 1974-07-25
Abstract: 1475013 Flexitime recorder SIMPLEX TIME RECORDER CO 25 July 1974 [25 July 1973] 32918/74 Heading G4T A flexitime recorder usable to correct individual records, e.g. to allow for authorized absence, comprises a pulse generator 30 for producing counting pulses, a plurality of resettable pulse counters 14a-14d for individual records, a plurality of lock-switches 16a-16d each of which is associated with a separate counter and is operable by an employee to record his presence, and a correcting means 52 and 62 for transmitting a pre-determined number of correction pulses to any chosen counter at a frequency higher than the counting pulses. Counting pulses are emitted by the crystal-controlled generator 30 at minute intervals along line 32. A programming unit 38 which contains a program, e.g. on a circuit board, works in conjunction with an AND circuit 42 to ensure that counting pulses only reach the switches 16a- 16d during pre-determined periods of the day, as specified by the program. Correcting pulses at 8Hz frequency are also produced by the generator 30, at output 34. Lock switch 22, operable only by authorized personnel normally prevents the correcting pulses reaching the correcting units 52 and 62. Unit 52 has a counter store 18a into which the correction is inserted by means of buttons 18b. On closing switch 22 correcting pulses from generator 30 reach unit 52, which co-operates with AND circuit 58 to cause them to appear at input 60 of unit 62 so long as the counter store 18a is non-zero, the contents of the store reducing by one for each arrival of a pulse at unit 52. The inverter 54 and AND circuit 50 ensure that pulses only reach unit 52 when timing pulses are not being transmitted along 32; this prevents errors in the correction of the stores 14a-14d. An addressing unit 62 routes the correction signals to the required counter store whose contents are then increased by the required number. The address of the counter store is input to unit 62 by means of knobs 20a and 20b. Correction pulses may be used to reduce the store contents by providing a means for inverting the pulses and having stores than can also operate decrementally.
