Title: Improvements relating to the production of colour-photographic copies on sensitized material comprising a plurality of layers
IPC: G03C7/14
Filed: 1932-07-21
Abstract: 409,287. Colour photography. GASPAR, B., 38, Innsbruckerstrasse, Sch÷neberg, Berlin. July 21, 1932, No. 20639. Convention date, July 29, 1931. [Class 98 (ii).] In copying multicolour master images on to sensitized material comprising superposed layers, the copying material is exposed to different coloured lights and the relative intensity or period of action of the different lights is varied to compensate for variations in the sensitivity of the layers. Exposure may be made by contact or optically and behind a coloured negative or diapositive or a multi-colour screen master image. In one form, the material is exposed to light from a lamp fitted with a slide or disc carrying different filters and the time of exposure to each coloured light is adjusted to give correct exposure for each layer. The appropriate exposure times are determined by exposing a test strip of the multi-layer material below a scale of graduated opacities and through filters similar to the copying filters. The copying filters may also be combined with a grey screen. In a modification, the layers are exposed simultaneously to differently coloured lights, the intensity of which is adjusted, e.g. by shutters, or by grey dry or liquid filters or by altering the spacial adjustment of the different light sources. A source of white light may be split into different coloured lights by optical elements such as prisms, reflectors, filters and the different colours reunited. An electric globe may be covered with two or more filter sectors and the relative intensities adjusted by partially covering or shading the different filter sectors. Adjustment is made in accordance with a test strip exposure and may be modified to give any desired predominance of colour. Specification 408,991 is referred to.

Title: Improvements relating to Data Handling Arrangements.
Inventor: MELLIAR-SMITH PETER MICHAEL
IPC: G06F12/0804
Filed: 1967-05-04
Abstract: 1,196,752. Data storage arrangements. INTERNATIONAL COMPUTERS Ltd. 1 May, 1968 [4 May, 1967], No. 20675/67. Heading G4C. An interconnected usage and modification indicator system for use with a data store and including a scanning means is disclosed. In a data storage arrangement comprising a first relatively slow storage means and a second relatively fast storage means, if a requested item of data is not found in said second storage means it is obtained from said first storage means and at the same time written into a location of said second storage means which has not recently been accessed. The second store is thus arranged to store only the currently most frequently used data. As shown (Fig. 1) the relatively fast access store 10 may be constructed from integrated circuits and have relatively small storage capacity whereas the relatively slow store 12 may comprise a magnetic core store of relatively large capacity, both stores being read in a nondestructive manner. Each location 14-44 of the store 10 comprises a portion B for the storage of a data word from the store 12, a portion A for the storage of the address (in memory 12) of the data word currently in the corresponding portion B and a portion F comprising two bistable devices for indicating the status of the corresponding data word. Thus, a first one of the two bi-stable devices is set to binary 1 whenever the corresponding data word is accessed or modified and is set to binary 0 whenever a cyclical, scanning device 50 constructed as a ring counter scans that indicator. Whenever a requested word is not found in store 10, the scanning device searches for an indicator with 0 state, starting from the point where the previous search ended. The first indicator so found is selected as the location into which the new word from store 12 is to be written. The second bi-stable device of each indicator F indicates whether the contents of the corresponding data portion B have been modified or not and if modification has occurred controls the re-writing of the modified data into store 21 prior to this data being itself overwritten. For facilitating the search for a requested data item in the store 10, the address portion 14A-44A of this store is constructed as an associative store. In modifications, the scanning by unit 50 may be random in nature, the scanning may be performed prior to the need for overwriting arising and groups of say four successive data words may be stored in each location of the store 10 (cf. Fig. 3, not shown).

Abstract: 1,086,543. Electronic organs. WURLITZER CO. May 11, 1966 [May 12, 1965], No. 20842/66. Heading G5J. An electronic organ is provided with a bank of manually actuable stops which can be reset simultaneously. As shown, a line of plastics stops 26 are mounted on a shaft 48. Each stop can be rocked in an anticlockwise direction from the position shown to a position in which detents 72 integral with the stop, are located on the other side of projections 84 on a pawl spring 76. Actuators 86 rigidly mounted on each stop are pivoted from the position shown in which electrical contacts 120 engage a fixed contact wire 126 to a position in which the contacts engage a fixed contact wire 128. The contacts constitute switch contacts for a printed circuit board 114, the instrument being of the electrophonic type. A shaft 148 extends alongside the actuators 86 and carries plastics cams 130 keyed to the shaft at 150 and held by C-springs 158 in a manner which permits them to be slid along the shaft so that they can be selectively positioned opposite cam surfaces 100 on the actuators. Operation of a push-button causes the shaft 130 to rotate in a clockwise direction to move the cams 148 to the position indicated in broken lines engaging the selected cams with corresponding cam surfaces 100 and thus resetting the selected stops. Axially displaced cams 342 and 346 are similarly mounted on a shaft 296 mounted on the other side of the actuators. The shaft can be rotated clockwise to anticlockwise by operation of a corresponding push-button and in each case according to the positions of the cams 342 and 346 selected ones of the stops 26 are simultaneously set.

Abstract: 1,140,373 Moulding filter elements. N. O. ROSAEN, B. O. ROSAEN, and O. E. ROSAEN. 11 May, 1966 [7 March, 1966], No. 20867/66. Heading B5A. [Also in Division B1] In manufacturing a fluid filter element, a sheet of nylon mesh filter fabric 16 is pressed into the folds on one side of a corrugated perforated metal backing sheet 10 by inserting rods 18 (Fig. 1, not shown), the assembly is clamped against a suitably profiled plate 23 and then placed in a moulding frame (Fig. 3, not shown), wherein epoxy resin is poured to form a frame in which the peripheries of sheets 10, 16 are embedded. In a simpler version, sheet 10 is used alone and serves as the filtering medium. In forming a rectangular filter element the sides are cast and heat cured one at a time. The sides receiving the corrugated edges of sheets 10, 16 may be reinforced by using metal powder as a filler or by layers of resin and glass fibres (36- 40) and rods (42), placed in the moulding frame under the sheet assembly and ensuring that the sheet edges do not penetrate the filter element frame. Another frame reinforcement may incorporate a handle (62), (Fig. 6, not shown). In making a circular filter element (Figs. 7, 8, not shown), corrugated spacers (67) replace rods 18 in a rectangular assembly as before, the assembly being then cut to circular shape and placed in a mould (68, 78), which is rotated as resin is introduced through aperture (82) to form the filter element frame centrifugally, rotation continuing during subsequent cold setting, hot curing and cooling steps.

Abstract: 1428571 Valves SOC MINERVE SA 4 May 1973 [5 May 1972] 21286/73 Heading F2V [Also in Division A5] A valve for use in a respirator system comprises ball closure members 3, 4, in a chamber 2 which control communication between an inlet E and an outlet S and between the outlet S and exhaust P and a diaphragm defining a control chamber 12 with a control port C, which diaphragm is integral with a rod for actuating the closure members. The ball 4 is normally held against the exhaust seat by inlet pressures but it is moved towards the inlet seat by the rod for a given pressure in chamber 12. The inlet seat is smaller than the exhaust seat so that, for a given inlet pressure, the pressure in chamber 12 which moves the ball 4 is greater than that pressure in chamber 12 which is overcome by the inlet pressure to move the ball 4 back on to the exhaust seat. Two such valves 13, 14 and a "trigger" valve 31 (Fig. 3) are included in a pneumatic respiratory system (Fig. 2). The trigger valve is a spring-biased diaphragm valve which connects an inlet 45 with an outlet 46 or an exhaust 40 to outlet 46. A pressure source is connected to the inlets of valves 13, 14 and the outlet of 13 is connected to the control of 14 so that they are always in opposite states. The switching and timing is controlled by the build-up of pressure in chamber 25 via a throttle 27. When the pressure in 25 reaches said given pressure the valve 13 will switch over as with valve 14 and air will be supplied via conduit 22 and a remotelycontrolled valve 19 to a mask 18. Throttle 28 and valve 29, during this phase, exhaust the chamber 25 until the lower pressure is reached when the valve 13 switches back again. The trigger valve is included to give air on patientdemand. Inhalation by the patient connects inlet and outlet of the trigger valve to supply pressure direct to chamber 25 so that switching takes place immediately to give the patient air. A valve similar to valve 29 may be placed in series with throttle 27 and, in another variation, the valving functions of valve 29 and its counterpart may be performed by a single valve (62, Fig. 5, not shown).
