Patent GB-489299-A (GB)
Title: Improvements in or relating to the chemical treatment of photographic images
IPC: G03C7/413
Filed: 1937-01-22
Abstract: 489,299. Colour photography. MURRAY, H. D., and SPENCER, D. A. Jan. 22, 1937, No. 2016. [Class 98 (ii)] Exposed photographic material of the kind having one or more photographic layers on each side of the support is colour developed with two different colour developing solutions by applying to one side a coating layer of one of the colour developing solutions which has been thickened by the addition to it of sufficient thickening agent to render it highly viscous when in position on the material or to render it capable of being set to a gel on cooling, and by applying to the other side a coating layer of the other colour developer solution which has been thickened in a similar manner, leaving the coatings in position for sufficient time for them .to develop the images in the photographic layers and then removing the coatings. Suitable thickening agents are gelatine, glue, gums, and boiled starch. In an example, a film bearing on each side a hardened gelatine layer containing a silver colour component image produced by exposure, development, fixing, washing, and drying is bleached in a bath containing potassium ferricyanide and sodium chloride, which converts the images to silver chloride. The images may also be bleached to silver bromide. The film is washed and surface moisture removed by a current of air. The bleached images are rendered developable by exposure to light. The coating of colour developer thickened with gelatine may be applied warm to one side by rollers, and allowed to cool or chilled, and a coating of a different colour developer is applied to the other side. The layers may be left in position from 4 to 6 minutes, and then removed by washing in or spraying with warm water or by scrapers or by a rotating wheel. The developed silver is removed with Farmer's reducer. The coating layer may be highly viscous instead of being allowed to set. Colour developing formulµ are given, and may include ethyl glycol and diethanolamine. Colour formers referred to are 1: 5-dihydroxynaphthalene, 1 : 3-diphenyl - 5 - pyrazolone, 1 - p - nitrophenyl - 3 - methyl-5-pyrazoloiie, 1-phenyl-3-furyl-5-pyrazolone, alpha-chlor-acetoacet-p-toluidide, and p-nitrophenylacetonitrile. The process may be applied to a film having two layers on one side of the support and one or two layers on the other side of the support. The process may be applied to an exposed film that has not been developed and bleached. Specifications 308,803, [Class 98 (ii)], and 420,356 are referred to.

Title: Improvements in or relating to pistons and piston rings therefor
IPC: F16J9/06
Filed: 1960-01-20
Abstract: 914,611. Pistons and piston packings. PERFECT CIRCLE CORPORATION. Jan. 20, 1960 [April 2, 1959], No. 2051/60. Class 122 (1). A compression ring 13 and oil ring 14 are mounted in a single groove 12 in a piston and are axially spaced and forced outwardly by a single spacer-expander 15. The compression ring is arranged to extend into an inwardlyextending channel 23 provided at one side of the groove by means of an upstanding rib 26, and the oil ring 14 is disposed in a channel 25 at the other side of the groove. The engaging edge of the compression ring may either be tapered or straight in which case the ring may be so shaped that it tends to twist upwardly at its outer periphery so that the edge meets the cylinder wall at a small angle; the twist also ensures that the ring engages the upper side of the groove near its upper periphery and the ledge 24 of the rib 26 at its lower inner corner. The oil ring comprises a bent strip preferably with rounded inner and outer edges. The spacer-expander 15 comprises two independent spring structures 30, 31, connected by axiallyextending struts 32. The upper spring member 30 consists of a number of elements 34 connected to the upper ends of the struts 32 and alternating with downwardly-inclined U-shaped spring elements 35. Upstanding ears 33 on the elements 34 engage behind the inclined inner face of an annular rib 22 on the under face of the ring 13 and so force the ring outwardly and into sealing engagement with faces of the groove. The lower spring structure 31 consists of horizontal U-shaped spring elements 40 connected to the lower ends of the struts 32. Each element 40 is bent to provide a slightly angled shoulder 42 engaging the inner periphery of the ring 14. Specification 881,932 is referred to.

Title: Improvements in sliding plate shutters for a photographic camera
IPC: G03B9/42
Filed: 1951-01-29
Abstract: 736,214. Photographic sliding plate shutters. BERGERHOFF, H. Jan. 29, 1951 [April 26, 1950], No. 2179/51. Class 98 (1). A sliding plate camera shutter comprises two shutter plates movable longitudinally in planes parallel to that of the image-recording surface and coupled by means of a pivoted lever in frictional engagement with one of the plates whereby both plates are movable simultaneously to provide an exposure slit between their adjacent edges, means for varying the slit width by relative longitudinal sliding movements of the plates, means for moving the adjusted shutter plates perpendicularly across the optical axis of the camera, and tensioning and release means connected to at least one of the shutter plates. As shown, the two shutter plates 6, 7 are slidably mounted in guides 2, 3 on a back plate 1 and are coupled by a lever 11 pivoted at 12 on the plate 7 and bearing a pin 16 guided in an arcuate slot 18 in the plate 7 and engaging in a vertical slot 19 in the plate 6, the parts being maintained in their adjusted relative positions by friction. The shutter is set by moving clockwise a rotatable cover plate (not shown) which caps the shutter before its pin-and-slot connection with a rotatable non-capping tensioning disc engaging a pin 29 on the plate 7 causes movement of the plates 6, 7 to the left tensioning the driving spring (not shown) secured to the pin 29 and the shutter is held set by engagement of the pin by the hooked end 50 of a lever 35. On releasing the cover plate it is spring-returned to uncap the exposure aperture. When the shutter is set the lever 11 is adjacent an annular toothed sector 23 which is rotatably supported by pins slidable in arcuate slots 22 in a front plate 21, the slit width is adjusted by rotating a pinion 25 on the front plate. Separate vertically slidable release members 43, 44 are provided for instantaneous and prolonged exposures. On depressing the member 43 the lever 35 is rotated anticlockwise to release the pin 29 while on depressing the member 44 an additional lever 38 is simultaneously moved anticlockwise to bring its hooked end 56 into the path of the pin so that the shutter is held open by it. If the member 44 is depressed further than is necessary to effect a bulb exposure it is latched in the depressed position by a detent 57, giving a time exposure. To ensure that for prolonged exposures the shutter aperture is fully open, a disc having a circumferential slot in which engages a pin 62 on the member 44 is rotated by the aperture adjusting means and prevents depression of the member 44 until the disc presents a radial slot to the pin 62 when the shutter slit width is equal to the exposure aperture. In a modification for instantaneous and bulb exposures only a single release member is provided which can be rocked into alternative positions in one of which it actuates only the lever 35. Specification 430,648 is referred to.

Filed: 1944-02-09
Abstract: 575,703. Remote control systems. ABBEY, A., (Arenes Aktiebolag). Feb. 9, 1944, No. 2418. [Class 40 (i)] In a device for synchonous transmission of motion, a source of current is successively connected by a current distributor at the transmitter to a number of field coils wound on electromagnetic cores, which form the stator of an electromotor at the receiver, the cores and also the unwound rotor having distinct poles at each end of the motor, the number of poles on stator and rotor at one end having no common divisor. The stator poles are excited successively, causing the rotor to be turned one revolution in a step-by-step manner by a number of impulses from the transmitter equal to the product of the number of poles on the stator and the number of the rotor. As shown in Fig. 1, the rotor has one pole less than the stator. The contact arm 5 moves in the direction of the arrow and energizes first coil S', then S<2> and so on, so that the rotor turns in an anticlockwise direction. Fig. 3 shows a cross section of the motor, the stator pole shoes 13 being mounted at the ends of magnet cores symmetrically distributed round the axis of the motor. The rotor has two hollow cylindrical end pieces, the pole shoes 16 being formed between recesses in the end pieces.
