[Class 39 (i)] [also in Group XX] Relates to a scribable sheet for use in a method of reproducing' drawings in which a luminescent layer coated on a rigid backing sheet as of steel is covered with an opaque lacquer layer which is scribed through to Produce the drawing, whereafter the fluorescent layer is excited as by X-rays or visible light, and a contact copy of the drawing is made on a light-sensitive sheet. According to the invention, the opaque layer contains a medium such as lead chromate which reduces fog by absorbing unwanted X-radiation and a medium such as beeswax which facilitates scribing, and may be applied m several coats containing contrasting pigments to render the scribed lines more clearly visible. The fluorescent layer may comprise barium chlorofluoride in a lacquer or synthetic enamel vehicle coated over an oil-type priming layer, and it may be covered with a transparent lacquer layer or sheet before applying the scribable coatings. These may consist the coloured pigment nitrocellulose lacquer containing lead chromate and beeswax, and may also contain magnesium silicate to give a matt surface. There may be two such coatings containing, e.g. blue or green pigment, dark in the lower coating and light in the upper,. Reference is made to a similar process in which the drawing is marked m opaque lines on the fluorescent layer. Specification 553,152 and 596,852 are referred to.

In a checking circuit for determining whether signals which should represent the " indicator " of a given binary coded word do or do not do this, an output signal is provided, indicating an error, when the sum of the number represented by the signals, the number of " ones " in the word and unity is not an integral multiple of four, where the " indicator " of a binary coded word is defined as the complement on three of the residue of the number of " ones " in the word with respect to a modulus of four. As described a multi-digit binary-coded decimal word has a two-digit indicator as defined above and is checked (a) to determine whether each decimal digit is less than nine, and (b) to determine whether the indicator is correct. Checking (a) is achieved by coincidence gates which determine whether an " 8 " bit occurs with either a " 4 " bit or a " 2 " bit and checking (b) by entering the bits of the word into a pyramid of elementary binary adders, each having three unity weighted inputs and a carry and sum output, and casting out all " fours."

Title: Device simulating the function of an electrothermal device
IPC: G01K11/12
Filed: 1974-04-09
Abstract: 1462461 Temperature indicators ROBERT PARKER RESEARCH Inc 9 April 1974 15717/74 Heading G1D The temperature of an electrothermal device 26 may be qualitatively or substantially quantitatively indicated by means of a device which simulates the function of the electrothermal device and comprises a layer of at least one liquid crystal composition 14 which is in heat exchanging relationship with a resistance heater 20 or 34 and an at least partially transparent insulating overlay over said layer having a heat capacity, size and geometry to relate to the cooling of the device 26. As described, the heater 20 or 34 has a thermal response which is proportional to the current or voltage applied to the appliance, and the lower or both transition temperature(s) of the liquid crystal composition(s) is preferably in the range of temperature developed by the heater 20 or 34. The overlay constitutes the major portion of a heat sink which is in heat exchanging relationship with the environment and provides a cooling response of the device which is proportional to the cooling response of the device 26. The variation in response of the liquid crystal composition to the heater 20 or 34 may be provided by employing a plurality of compositions having different temperature transition ranges whch experience together the same temperature Fig. 5, (not shown). Alternatively, as shown in Fig. 2 a single composition is employed which experiences a temperature gradient. Thus a bar 44, 46 is initially formed centrally at the transition temperature, splitting into two and moving outwards as outer regions reach the transition temperature and inner areas exceed the transition range. In a modification, a temperature gradient activates the liquid crystal to show the word "warm" at a region close to the heater, the word "hot" being activated at a region further from the heater Figs. 3 and 4 (not shown). The liquid crystal transition temperatures lie in the range 100-200‹F, and the crystals may be microencapsulated and be cholesteryl esters. The insulation overlay is plastics or polymeric sheet e.g. of a polymethacrylate, polycarbonate, polyvinylchloride, or polypropylene. The heater may be a resistance heater sheet,.film, foil of, for example, carbon impregnated paper or metal foil. Where a temperature gradient is required, a resistance wire may be employed, the heater generating a temperature below 400‹F.

A PN junction 13a is formed between regions of opposite conductivity types in a semiconductor body 10 and reaches the surface of the body in an area covered by a masking layer 11, and an electrical connection to one region 13 is provided by an electrolytically deposited metallic layer 16 extending over that part of the surface of the region 13 which is not covered by the masking layer 11 and also over the layer 11 at least as far as the junction 13a. As described, a slice 10 of N-type silicon is provided with an oxidized layer 11 which acts as a mask for the diffusion of boron through an aperture 12 to form a P-type region 13. A ring of chromium is evaporated on to the oxide layer 11 surrounding the aperture 12, and lead, cadmium or tin is electroplated on to the exposed surface of the region 13 and allowed to extend over the chromium-covered part of the oxide layer 11. The electro-deposited metal is then melted so that surface tension forces pull the molten metal into a globule (the chromium not being wetted by the molten metal) which, upon cooling, solidifies into a raised contact portion 16. Alternatively, the electrodeposited metal may be fused to a copper ball which will then form the raised contact portion.

Class 110(3) [Also in Group XII] A gas turbine plant having a combustion chamber including a pilot injection device and a main fuel injection device located upstream of the pilot device fed from a common fuel supply has means for varying the distribution of fuel between the two devices so that. during operation, a minimum quantity of fuel is always fed to the pilot device and has part of the flow of air deflected upstream of the main injection device and re-introduced into the flow downstream of the combustion zone. Fuel is supplied to a combustion chamber 1, Fig. 1, by means of a burner 5 and pilot burners 3 located downstream of the burners 5. The fuel supply conduits 4, 6 are controlled by a slide valve 11, Fig. 6. The valve 11 I is loaded by a spring 14 towards the left hand end of the casing 10 to which th.e fuel is supplied by a pipe 9. At low fuel flow, the valve 11 is at the left hand end of the casing 10 so that fuel is supplied through the longitudinal grooves 13 to the conduits 4 and pilot burners 3 only. As the fuel flow increases, the valve 11 moves to the right and allows fuel to flow through the conduits 6 to the burners 5. A passage 12 through the valve 11 balances the static pressures on each end of the valve. To vary the value of the fuel pressure at which this change over occurs in accordance with the air flow, a threaded plug 15 is provided to vary the loading of the spring 14. The plug 15 is rotated through gearing 16, 17 by means of a piston 18 subject to the air pressure at the compressor discharge. An annular form of combustion chamber is also described.
