Patent GB-1592839-A (GB)
Title: Method of obtaining a target colour on colour photosensitive photographic material
IPC: G03B27/73
Filed: 1978-04-12
Abstract: The target colour is illuminated with a light source, the ratio of three primary colours - red, green and blue - being determined. The illuminated target colour is compared with a data bank which comprises a plurality of colours. A reference colour which is closest to the target colour is read out from the data bank. A group of one or more colour filters is identified, these being used for producing the reference colour. The exposure times for the colour filters which are necessary for reproducing the target colour on the colour-photographic material when it is developed are determined. Undeveloped colour-photographic material is illuminated through the colour filter during periods of time which have been determined for each respective colour filter. The exposed colour-photographic material is developed in order to reproduce the target colour thereon. The simple, cost-effective method is suitable for the synthesis of a target colour by step-wise exposure of a photographic recording material with light-variable colour. The method can be used both on positive and on negative photographic recording materials. Once a defined colour has been synthesised it can be reproduced repeatedly. <IMAGE>

A straight-bar rib knitting machine has main draw-off means comprising an endless conveyer which carried hooked draw-off instruments which engage and draw-off further fabric already drawnoff by initial draw-off means. As shown, in each knitting section an initial draw-off bar 9 with hooked points 10 as described in Specification 1,000,292 is carried on chains 11 and 11a (not shown) connected to a driven draw-off spindle 13. The main draw-off means comprises an endless conveyer made up of chains 18 and 19 (not shown) carried on sprocket wheels 20, 20a and 22, 23 (not shown) carried by a frame pivoted on a driven spindle 26 to which wheels 20a, 23 are secured so as to drive chains 18, 19. Five spaced bars 28, 29, 30 on chains 18, 19 carry point 31 with end hooks 31a. The frame is pivotable between an adjustable operative position and an inoperative position. A stop 42 on the frame is pivotable between an inoperative position and an operative position permitting bars 29 to pass in one direction only. Points 10 are controlled by cams 21 to move in a path which intersects the path of hooks 31a which is adjustable. Rollers 45, 46 guide the chains 18, 19 upwardly at T away from the fabric F. In operation, after points 10 have received the first course of loops, clutches 14 and 32 rotate respectively clockwise and anti-clockwise, Fig. 2, the bar 28 nearest behind stop 42 is driven against the latter. As knitting ensues, bar 9 is driven through chains 11, 11a and clutch 14 to a take over position with points 10 just behind hooks 31a to present the fabric thereto. Spindle 26 is then driven anticlockwise and spindle 13 ceases to rotate. In a modification, Fig. 3 (not shown), the bars carrying the points 31 are pivoted to the chains and, at the end of their draw-off runs are engaged by a fixed guide to tilt the hooks out of the fabric.

Title: Improvements in or relating to aircraft arrester hooks
IPC: B64C25/68
Filed: 1946-05-14
Abstract: 611,954. Aircraft arrester hooks. FAIREY AVIATION CO.; Ltd., CHAPLIN, H. E., and BEALE, R. D. May 14, 1946, No. 14537. [Class 4] In a folding wing aircraft with a tricycle undercarriage in which the folding of the' wings causes the centre of gravity of the aircraft to move behind the rear axle of the undercarriage, the aircraft tail is supported when the wings are folded by a strut 15, which is also an arrester hook for engaging wires on a landing deck for stopping the aircraft, retractible manually into a housing 10a near the tail of the aircraft. The arrester hook 15 is pivoted about an axis 16 to the aircraft and is extended and supported by a pneumatic jack 20 whose piston 19 is pivoted at 18 to a lever 17 integral with the hook and whose cylinder is pivoted at 21 to a bracket 21a on the aircraft. The exhaust valve 36 of the jack 20 is automatically closed by a connection 39, 38 to a lever 37 (see Fig. 4), fast on the shaft 16 when the arrester hook 15 is (manually) retracted, a lost motion device in the connection preventing the automatic opening of the valve 36 by extension of the strut. The valve 36 is also connected by a trip lever 43 pivoted to a bracket 43a on the housing and by a rod 42 connected to the wing folding mechanism so that when the wings are unfolded the trip lever 43 moves to open the valve, while when the wings are folded a de.tent 44 on the lever 43 passes the operating rod 41 of the exhaust valve without moving it. The inlet valve 34 is connected by a rod 35 to a bolt 24 engaging an eye 22 on the arrester. hook and an apertured yoke 23 inside the housing 10a so that the hook is unbolted at the same time as the valve 34 is operated to extend the arrester hook. The valve 34 is in series with a further valve 31 connected through a rod 30, bell-crank 29 and flexible cable 28 with a lever 25 pivoted at 26 to the hook 15 for ejecting the arresting wire from the aperture 27 of the arrester hook; the valve 31 is open only when the lever 25 is in its rearward position ready for operation. A stop 33 prevents the arrester hook being stowed with the lever 25 in its forward position.

Title: Improvements in methods of making ice and apparatus therefor
IPC: F25C1/08
Filed: 1934-05-15
Abstract: 438,600. Ice-making. WUSSOW, R., 25, Pestalozzistrasse, Charlottenburg, Berlin, and FECHNER, F. W., 112, Eppendorferlandstrasse, Hamburg, both in Germany. May 15, 1934, No. 14593. Convention date, May 15, 1933. [Class 29] Ice-blocks d are formed within open-ended cylindrical or conical tubes c extending through evaporators b submerged in the liquid to be frozen in a tank a, and when thawed-off by passing warm refrigerant in a reversed direction through the evaporators float to the surface, whence they may be raked off to a shoot m as by a conveyer belt k. To avoid freezing beyond the ends of the tubes, or at the ends if the tubes extend beyond the walls of the evaporators as shown, insulating rings f, Fig. 2, may be located on the evaporator walls at the tube mouths. The Specification as open to inspection under Sect. 91 comprises also the following : The water to be frozen may be agitated by pre-cooled air admitted through nozzles at the bottom of the moulds, and the lower walls of the evaporators may be insulated by air jackets. Apertured wood plugs may be inserted in the bottom ends of the cells to prevent freezing at the ends. In the manufacture of clear ice from sea water, the evaporatbr b<1>, Fig. 3 (Cancelled), is located between a tank a<1> and a conduit m in communication with a pre-cooler p for the sea-water, the unfrozen chilled liquid being discharged from the tank a<1> through the pre-cooler in counterflow to the incoming sea water. Sediment is discharged through a valved branch o. The ice blocks may be formed in successive stages by admitting the water intermittently to the bottoms of the cells through check valves e<1>, Fig. 6 (Cancelled). As ice forms at the bottom of the cell it pushes up the block and more water enters through the valve and in its turn becomes frozen. This arrangement may be employed with deep conical cells in an immersed brine-cooled chamber, and with cells in a shallow brine chamber a<1>. In the latter case the ice block is engaged by spring grips i<1> to hold it up as it is pushed out of the cell, and the block may be broken against a fixed baffle g<1> from which the pieces drop into a shoot h<1>. A system of pipes from the compressor condenser and receiver to several evaporators in parallel is also described, with refrigerant valves for each evaporator to enable them to be thawed off in succession. This subject-matter does not appear in the Specification as accepted.

Filed: 1946-05-15
Abstract: 641,713. Heating and cooling buildings &c. CARRIER ENGINEERING CO., Ltd. May 15, 1946, No. 14747. Convention date, June 28, 1945. [Class 64(ii)] An air-heating or cooling system comprises one or more units 4 including heatexchange means for heating or cooling air, connected by a passageway 5 to a source 2 of heating or cooling-medium and to an outlet passageway 7, means, e.g. an expansion tank 8, for imposing a predetermined pressure on the medium in the passageway 5, and valve control means, responsive to the pressure of the heating or cooling medium in one of the passageways and to the temperature of an area or areas served by the unit or units 4, for controlling circulation of the heating or cooling medium to the unit or units 4. In the form shown, the valve 6 is provided with two alternative paths 17, 18 between the inlet 15 and outlet 16, the paths being controlled by the poppets 13, 14, the poppet 13 is actuated by a bellows 19 responsive to the pressure of the liquid flowing through the valve and the poppet 14 by a bellows 22 forming part of a temperature responsive actuating element, the chamber containing the bellows 22 being connected by a pipe 23 to a bulb arranged in the space the temperature of which is to be controlled. The system is arranged so that when heating fluid is being circulated its pressure is below that necessary to compress the bellows 19, so that the path 17 is open and 18 closed. Flow of fluid will continue so long as the poppet 14 is in its lower position, i.e. so long as the space temperature is such that the bellows 22 is expanded. When cooling fluid is being circulated, its pressure is made sufficient to compress the bellows 19 so that the path 18 is open. Flow of cooling fluid continues as long as the poppet is in its upper position. In the system shown, the liquid is circulated by a pump 3, and the pressure in the circuit is maintained by a tank 8 fed with additional liquid by a pump 9 when a fall in the temperature of the liquid in circulation causes a thermostatic element 11 to actuate a pressure control device P which actuates the pump 9. In a modification, the level of liquid in the tank is controlled by two float-operated valves at two different levels, either being brought into operation according to the temperature of the liquid being circulated and the pump 9 is omitted. Specifications 639,767, [Group XV], and 641,712, [Group X], are referred to.
