Title: Conversion of image information into magnetic information
IPC: G06K9/20
Filed: 1973-03-14
Abstract: 1392975 Optically written moving domain systems; facsimile PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 March 1973 [17 March 1972] 12245/73 Headings H3B and H4F An optical image is converted into an electrical signal by projecting the image on to a sheet of bubble domain material with a sufficient intensity to heat the sheet and thus to create or destroy bubble domains, the resulting domain pattern being propagated to one or more domain detectors to form the electrical signal. The domain sheet is maintained either near its Curie point, in which case the incident image will remove domains from a previously filled sheet, or near its compensation point in which case the incident image will create domains. The domains may be propagated along a closed path to a single detector, or in rows to multiple detectors. Propagation may be by an arrow head pattern and a variable bias field, or by the influence of other domains moved in an adjacent sheet as in Specification 1,373,298. Fig. 2, shows four parallel domain paths 12- 16, initially filled with domains by loops 10. The image of a letter K is projected on to the sheet at its Curie point to remove domains, and this stored image is read by propagating the domains to loops 16. The domain paths are read one after another, each having its own variable bias field; gates 19-25 connect the paths in turn to a counter 18. Alternatively by varying the main bias field all the paths are propagated at the same time and horizontal rows are thus read out. In this case a single detector may be used if a horizontal path connects the lower ends of the four paths, along line 26, so that the domains may be moved past a single detector. In Fig. 3, a closed path of T and I bars is used to propagate the image past a single detector, and the image is not lost during reading. A return path may also be provided in Fig. 2, or the domains may be electrically rewritten after reading. In Fig. 5, the image is in the form of the presence of domains, and is thus either a white image formed at the compensation point or a black image formed at the Curie point. An adjacent sheet 54 has paths filled with domains which couple to those in the image and propagate it to the detector loops 51. Either the whole image can be moved at once, or it can be moved row by row as individual rows 55 in sheet 54 are operated. If a single detector is to be used the whole image is propagated to the left in Fig. 5, and each vertical column of the image is then propagated along line 58 when it reaches the edge of the sheet to the detector.

Title: Improved method of producing smooth surfaces on metals and metal articles in annealing them to restore ductility
IPC: C22F1/00
Filed: 1937-04-29
Abstract: 489,744. Annealing; pickling. FINSPONGS METALLVERKS AKTIEBOLAG. April 29, 1937, No. 12279. Convention date, May 5, 1936. [Classes 72 and 82 (ii)] Smooth surfaces are produced on metals and metal articles by annealing them, to restore the ductility lost by cold working, in an inert atmosphere, while excluding air therefrom and then pickling the annealed material in a bath of sufficient acidity to dissolve the oxides thereon but insufficient to attack the metallic surface proper so that a glassy surface is produced. The pickling bath may contain tartar or tartaric acid, acetic, sulphuric or extremely dilute hydrochloric acids, the acid content being 2 per cent or less. In one form of apparatus for carrying out the process, the articles 2 are supported on a frame 5 on the muffle 3 of a furnace 1, the ends of the muffle being immersed in a water bath 4 containing the acid. The muffle 3 is filled with dry inert gas or with water vapour, or with nitrogen and after the annealing has been completed, the frame 5 is lowered so that the articles 2 are immersed in the bath 4. In another form, Fig. 2, the articles are passed continuously on a conveyer 6 through a water bath 41, and the muffle which has bent ends 31, 3<2> and thence through the acid bath 4<2>. If the metals are in the form of long rolled lengths, they may be pulled through the baths and the muffle.

Inventor: STEFANI NICOLA
IPC: G01J1/40
Filed: 1918-07-29
Abstract: 121,583. Stefani, N. July 29, 1918. Exposure meters. - The necessary time of exposure in photography is determined by the use of screens of various opacities used as focussing screens or for viewing the image produced on an ordinary focussing screen. In the form shown, the appliance used consists of a strip of film having a non-tinted translucent portion M for focussing and a series of zones a - - d of increasing opacity, each marked with the exposure required when the particular zone just obscures the image produced by the camera lens. The film is attached by gummed paper or otherwise to the end of a sensitive film PF. When using plates, a series of separate screens may similarly be used as focussing screens, or a film such as that shown mav be mounted on rollers on the frame of the ordinary screen. In a further modification, separate screens of uniform opacity may be superposed so that the number required to obscure the image gives a measure of the required exposure.

Abstract: 1328295 Making shadow masks ZENITH RADIO CORP 30 April 1971 [1 May 1970] 12368/71 Heading B3A [Also in Division H1] In the manufacture of a colour television tube of the shadow mask type, the shadow mask and the fluorescent screen are both made by photoresist processes by exposure through respective masters with which they are accurately aligned so that completed masks and screens are interchangeable. The mask blank and its frame are preferably formed separately and oxidized, preferably by heating in an oxidizing atmosphere to relieve stresses at the same time, and after they have been accurately aligned and welded together the assembly is heated to 470 C. to relieve stresses. The completed blank B, Fig. 4, is coated on both sides with a photo-resist and mounted by its springs 14 between two masters M1 and M2 which are accurately located against locating pins 16 and 16<SP>1</SP>, and is exposed through the masters from light sources S1 and S2, either successively or simultaneously. The exposed areas are then removed and the mask is treated with a chemical stripper such as hydrogen chloride to remove the exposed oxide areas, and etched from both sides, preferably from the convex side first, to provide the required pattern of openings (Fig. 5, not shown). Finally the remaining photo-resist is removed and the etched areas are subjected to chemical blackening. The masters M1 and M2 may be made by inserting a standard mask in the apparatus shown in Fig. 4 and using it to expose resistcoated plates.

Title: Improvements in or relating to fuel-controlling means for two or more internal combustion engines geared to a common output shaft
IPC: F02D25/02
Filed: 1945-05-18
Abstract: 631,795. Speed governors. DAVEY, PAXMAN & CO., Ltd., PAXMAN, E. P., and HOWE, A. G. May 18, 1945, Nb. 12604. [Class 57] [Also in Group XXVII] Means for controlling two or more engines geared to a common output shaft comprises a manually-operable device for progressively setting regulating means of each engine to vary the fuel supply thereto and for progressively adjusting simultaneously the load setting of an engine speed responsive governor of each engine and means operable by the governor of each engine to operate the regulating means so as to cut off or reduce the fuel supply to each engine when the speed of the engines exceeds that determined by the load setting of the governors. The embodiment of the invention described comprises two Diesel engines connected to a common gear box and each engine drives through a reverse gear to a pinion which engages with a main gear wheel carried on a propeller shaft. A common manually controlled member (not shown) operates a control rod 9 of each engine and each control rod operates a cam 1 controlling the fuel supply of its particular engine and also actuates a load setting control of the engine governor (not shown). The controls of one engine only are shown. The rod 9 operates the cam 1 through members 5, 6. Member 6 is adjustable by means of a threaded pin and nuts 10. The cam can bear upon an adjustable pin 18 carried by a lever 19 pivoted on a shaft 25 in the governor housing and connected by a telescopic link 21 to the operating bar 23 of a fuel pump. The link carries a strong spring 22 which enables it normally to operate as a fixed link. The shaft 25 extends into the housing. Fixed to the shaft is a sleeve 28 having an arm 29 which can co-operate with an adjustable pin 30 or the lever 19. A torsion spring within the sleeve is connected to the sleeve at one end and to the lever 19 at the other. When the engine speed exceeds that determined by the load setting of the engine governor the governor operates an arm 26 within the governor housing the arm being fixed to the shaft. The shaft is rotated and moves the arm to move the lever 19 in a direction to reduce or cut off the fuel supply. The link 21 is made telescopic so that the operating bar 23 can be moved at starting to provide an increased fuel supply by compressing the spring or moved to the right to cut off the fuel when desired. Adjustment so that each engine receives the same amount of fuel is carried out by means of the pin 18. It is stated that governors of the type described in Specifications 516,804 and 527,258, [both in Group XXIX], are employed but other suitable governors could be used.
