Title: Improvements relating to Photographic Processing apparatus
IPC: G03B17/52
Filed: 1966-11-22
Abstract: 1,156,463. Photographic processing apparatus; cameras. INTERNATIONAL POLAROID CORP. Nov.22, 1966 [Nov.26, 1965], No.52277/66. Heading G2A. A camera with built-in processing apparatus producing colour prints by diffusion transfer is closely similar to the type disclosed in Specification 1, 156, 464, a photo-sensitive imagerecording sheet 52 being fed by guide 143 and driven rollers 140,142 to follow a U-shaped path through processing liquid 98 while, after a delay, an image-receiving sheet 54 is fed by roller 149 and curved guide 148 to deflect and contact the end of sheet 52 issuing from liquid 98 whereby the two sheets are drawn through and compressed by rollers 144, 148. Sheets 52, 54 are stored in two face-to-face stacks in pack 50, sheets 52 being advanced from the pack by shoes 114 having plastics foam surfaces to frictionally engage the foremost sheet. The shoes are carried on arms (116, Fig. 4, not shown), pivoting on a shaft (118) mounted between brackets (120) slidable on tracks (122). In the disengaged position, ends (126) of arms (116) are pressed against members (127) to raise the shoes against spring (124). Rotation of hand-crank (46) slides brackets (120) along their tracks through links (128) and a gear and lever system, and the shoes advance one sheet. Rotation of crank (46) also makes the exposure and starts the processing cycle, the end of the stroke switching on electric motor (160) driving the rollers and cams of a control system, Fig. 3 (not shown). Cam (159) pivots arm (152) through push-rod (156) whereby friction-plate (82) is displaced downwardly to advance one imagereceiving sheet (54). The period of processing in liquid 98 is variable by changing the motor speed, or in a manually-driven version, by adjusting the speed governor. To ensure operation of the camera in an upright position only, a position-sensitive switch is included in the motor circuit. The batteries may operate a heater for temperature control of liquid 98 and may also operate a timer giving a signal when the sheets 52, 54 may be separated. In a modification, curved guide 148 is of deformable plastics and presses sheet 54 into driving contact with roller 149 when released from a disengaged position by a cam-operated tripping arm when the sheet reaches a predetermined position.

Abstract: 1,177,995. Portland cement. KOMAREKGREAVES & CO., and CAMERON & JONES Inc. 22 Nov., 1967, No. 53188/67. Heading C1H. A portland cement kiln feed comprises a briquetted mixture, free from carbon and water, derived from a CaCO3 containing material and an aluminium silicate containing material. The feed can be obtained by decarbonating a calcareous material at at least 1400‹ F., dehydrating an argillaceous material together with corrective components, e.g. sand and/or iron ore either by heating it to at least 1000‹ F., or by mixing it with the cooled decarbonated material (which is therefore hydrated) and briquetting a mixture of the two materials at at least 5000 lb./sq. inch. The feed can also be obtained from a slurry of the components which is partially dried, nodulized, calcined, crushed and finally briquetted.

Abstract: 1,202,265. Vehicle washing apparatus. SPARKBROOK DEVELOPMENTS Ltd. 24 Feb., 1969 [24 Nov., 1967], No. 53495/67. Heading B7J A vehicle washing apparatus comprises a horizontal rotatable cylindrical brush 11 freely suspended at all times from a member 4 which is guided to move in a vertical path, the member 4 being mounted in a frame 1, 2, 3 and suspended by wires 5 from pulleys 6 and guided by rails 7. The wires 5 pass over pulleys 8 and are connected to a counterweight 9. Spray pipes 14 and 15 are connected to a detergent and a water supply respectively. The pipe 14 spraying detergent on to the brush 11 and the pipe 18 spraying water downwards at an angle of about 60 degrees to the vertical so as to miss the brush 11, Fig. 2, which is rotated by a reversible motor 12 mounted on the member 4, which is lowered by a motor 10 which lifts the counterweight 9. The motors 10 and 12, solenoid valves in the water and detergent supplies and a pump for the detergent are connected in an electric control system operated from a control box 17, together with limit switches on the column 1 engageable by the beam 4 to limit the range of vertical movement of the brush 11, the upper switch being adjustable to suit the vehicle height. A vehicle is driven in the direction of the arrow A in Fig. 2 so that the vehicle front comes in contact with the brush in its lowest position. The brush is rotated in a counter clockwise sense as seen in Fig. 2, and the beam 4 is raised so that the front of the vehicle is washed. When the brush reaches the roof level of the vehicle the hoist motor stops and the sense of rotation of the brush is reversed, and the roof is washed as the vehicle moves forward, the water spray rinsing off loose dirt after the passage of the brush. When the brush reaches the back of the vehicle, as seen by the driver through a system of mirrors, Fig 3 (not shown), the vehicle is stopped and the brush descends washing the back surface of the vehicle. The brush is then returned to its raised position by the counterweight. The brush may start in its raised position and thus wash the front of the vehicle twice. The apparatus may operate semi-automatically, the washing cycle being started when the vehicle passes over a pressureswitch (18).

Maleinized linseed oil fatty acid (one maleic anhydride residue per molecule fatty acid) was reacted with an equimolar amount of A to give a monoester of the latter, and the latter was reacted with propylene oxide in the presence of a tertiary amine catalyst to form the monoester of propylene glycol and to leave one free carboxylic acid group. Maleinized linseed oil fatty acid was reacted with 2,2,4-trimethyl-1,3-pentane-diol to form the monoester, and the latter was reacted with an equimolar amount of propylene oxide. Maleinized safflower oil fatty acid was reacted with diol A, and the monoester produced reacted with a mixture of oxides of general formula where x, y and z are integers and x+y+z is 4-6.

Abstract: 1,151,663. Rollers. PHILIP CAREY CORP. 28 Nov., 1967 [9 Feb., 1967], No. 54130/67. Heading F2U. A conveyer roll for use, e.g. in steel furnaces and capable of continuous use at temperatures of 2000‹ F. and above comprises annular discs of asbestos millboard compressed axially on a shaft, the peripheral surface of the discs being heated to sintering temperature to fuse it to give a continuous ceramic surface to the roll. The roll may be produced by first heating the assembled discs to about 2000‹ F. to dehydrate and shrink the discs, then adding additional shrunk discs to form a roll of the desired length, and finally sintering the surface. Alternatively the roll may be sintered first, and then reheated to produce shrinkage of the discs, after which additional discs are slid on to the shaft and surface sintered and then reheated to 2000‹ F. while under axial compression to produce the completed roll.

[Also in Division G3] A capillary viscometer comprises two capillary tubes 5 of the same dimensions mounted in a chamber 11 through which the fluid under test flows, each capillary tube being connected at one end to a constant volume hydraulic pump 3, the inlets 2 for which are adapted to be positioned in the first case in the chamber 11 and in the second case in a reservoir 1 in the chamber 11, each capillary tube being connected at both ends to a differential pressure transmitter 8, the first tube being also connected to waste and the second back to the reservoir. The apparatus described is used in a blending operation where a sample of blended fluid passing through the chamber 11 is extracted by one of the constant volume pumps and supplied to one of the capillary tubes under pressure while the other pump takes a sample of fluid from the reservoir, which fluid is a standard of viscosity substantially the same as the desired viscosity of the blend, and passes the said sample to the other capillary tube under pressure, creating a pressure drop across the capillary tube which pressure drop is compared with the pressure drop in the other capillary tube by means of the differential pressure transmitter 8, any difference between the two pressures causing the differential pressure transmitter to actuate a control device to rectify the blend composition.
