Title: Single lens reflex camera
IPC: G03B7/099
Filed: 1976-12-16
Abstract: 1531839 SLR cameras ASAHI KOGAKU KOGYO KK 16 Dec 1976 [17 Dec 1975] 52690/76 Heading G2A An SLR camera has a photodiode 16 positioned to receive light reflected from the shutter or film and used to indicate shutter time before shutter release (the reflex mirror being partially transparent for this purpose) and to control shutter time upon release. Before shutter release with the diaphragm fully open, an ammeter 28 or a digital display (not shown) indicates a shutter time computed by a circuit comprising the photodiode 16, a resistor 19 set according to film speed and a resistor 30 set according to a pre-set aperture value. Upon shutter release, the diaphragm stops down to the pre-set value, a switch 32 connects a fixed resistor 31 in place of the variable resistor 30 and a timing switch 24 opens to initiate charging of an integrating capacitor 25. Capacitor 25 controls a shutter closing electromagnet 38. Optionally, a preview button is provided for connecting in the fixed resistor 31 before shutter release to allow exposure time to be indicated with the diaphragm stopped down.

Title: Electronic computer with a device for controlling jumps in microprograms
IPC: G06F9/26
Filed: 1974-12-06
Abstract: 1472270 Microprogram controlled processor ING C OLIVETTI & C SpA 6 Dec 1974 [28 Dec 1973] 52861/74 Heading G4A A microprogram controlled data processor includes a group of bi-stable circuits and is arranged to read a data word into the group of bi-stables, to select any one of the bi-stables and set the selected bi-stable to a state determined by whether a specified logical condition is or is not met, and to select any one of the bistables and execute or not execute a jump in the microprogram depending on the state of the selected bi-stable. The processor includes a microprogram read only memory 12 providing microinstructions to register 13 from where they control matrix 14 to provide the appropriate control signals to operate the processor. Part I of register 13 is used only for program jumps (see below), gate 207 normally being blocked. The ROM is normally addressed from register sets 19, 20 which are loaded via registers 17, 18 fed from buses 15 and 16 respectively which are coupled to the outputs of logic units UA, UB, shift network 36, the jump control bi-stables 30, and random access memory 11. The jump control flip-flops are shown in detail in Fig. 2. All the gates 80-87 and 100-107 at the inputs of flip-flops 50-57 are enabled by control signal CD13, or CD14 to read into the flip-flops a word from a register RA in set 19 or RB in set 20 via gates 120-127 and 130-137 depending on which control signal is active. Flip-flop 50 may be set by a signal DR70 via gate 34 in the presence of control signal CD15 at gate 88a. Similarly flip-flop 51 may be set by signals UZA or UZB in the presence of signals CD11 and CD12 respectively and flip-flop 52 may be set by signal URO4 in the presence of control signal CUO5. The various signals used to set individual flip-flops are indicative of various logic signals, e.g. an arithmetic unit carry &c. Decoders 68, 78 select one of their eight outputs in response to signals R1, R2, R3, one of the decoders being selected depending on the state of signal R5 so that any selected flipflop may be set or reset individually. A decoder 200 transfers the output D100-D107 of one of the flip-flops to its outputs 201, 202 in true and complement form in response to signals R1, R2, R3, and, by setting signal S4 to an appropriate state, a signal passes one of gates 203, 204, and gate 205 to produce signal AS and cause a microprogram jump by enabling gate 206 (Fig. 1) to address the RoM with the jump-to address in the current microinstruction, depending on the state of the selected flip-flop 50-57. All the control signals, e.g. R1, R2, R3, R5, CD11 &c., are generated by matrix 14 from microinstructions.

Abstract: 1455425 Making composite tubes; jointing FOUNDATION OF CANADA ENG CORP Ltd and BVS 15 Nov 1973 [20 Nov 1972] 53140/73 Headings B3A and B3V In a composite tube for withstanding high internal pressures at low temperatures in which an outer envelope is made of a material having a larger coefficient of expansion than that of the material of an inner tube, the fit of the envelope on the inner tube at ambient temperature is such that the desired hoop stress in the tube due to differential thermal contraction does not develop until the composite tube has reached the low operating temperature. The envelope may be in the form of a sleeve, spaced hoops or a wire, ribbon or cable. Formulae (8), (13) are included in the Specification for determining the initial difference in diameter between the outside of the inner tube and the inside of the envelope for a tube fixed at the ends and one additionally stressed axially, e.g. by the presence of a valve. If the initial difference does not permit a sliding fit, the tube may be made under-size and the composite expanded beyond the elastic limit of the tube in order to produce the desired initial fit, or the envelope may be shrink-fitted. Alternatively, the tube may be expanded and a helical bandage applied, or the bandage may be applied to a sleeve and the tube inserted in the sleeve which offers no resistance to contraction.

Title: Method and apparatus for combusting cabronaceous fuel
IPC: F23C6/04
Filed: 1976-12-23
Abstract: To ensure that the process is flexible with respect to the fuels which can be used and that also the utilisation of, for example, sulphur-containing fuels is possible, the process operates as follows: A first mixture (18) of carbonaceous fuel (10) and air (14) is burned in the presence of a catalyst (25) under at least approximately adiabatic conditions. The catalyst (25) operates at a temperature which is above the instantaneous auto-ignition temperature of the first mixture (18) but below a temperature at which a noticeable formation of nitrogen oxides would take place. The waste gas from this combustion is mixed with a fuel-containing component (32) other than the first mixture (18), and the mixture (40) is homogeneously burned in order to produce a waste gas (50) which can be used as an energy source. The fuel in the said fuel-containing component (32) can - in contrast to the fuel (10) in the first mixture (18) - also be a fuel which would poison the catalyst and/or which is difficult to vaporise and to mix with air. The process is intended especially for producing a hot waste gas for use as a heat source (for example in an oven) or as an energy source (for example in a turbine installation). <IMAGE>

As shown in Fig. 1, the slot has two right-angle bends 6, 7 to create stock turbulence, and the passage 9 has an outlet nozzle 8 between the bends. Alternatively, as in Fig. 2 (not shown) gas may be supplied to the slot through sintered metal or ceramic plates (108) in the roof and base of the slot upstream of the right-angle bends (106), (107). In a third embodiment (Fig. 3), stock turbulence is created at the downstream end 209 of a chamber in the slot, the chamber having a concave roof 207 opposite the stock inlet 202 and a convex bottom 206 opposite a gas inlet 208. An adjustable flap 215 may be fitted to overlie the machine wire. The depth of the slot may increase towards the slice opening to allow for the increased volume of the stock on foaming. Although a foam stabiliser is not necessary, starch or carboxymethylcellulose may be used.

Abstract: 1,139,497. Purifying chlorosilanes. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSALT. 1 Dec., 1967 [2 Dec., 1966], No. 54898/67. Heading B1L. Chlorosilanes, particularly silicon tetrachloride or silicochloroform, are separated from reaction mixtures thereof with carbon monoxide, carbon dioxide or hydrogen by absorbing the chlorosilane in a countercurrent stream of an inert liquid which has a boiling point above that of the chlorosilane the chlorosilane being subsequently released from solution by heating to a temperature above the boiling point of the chlorosilane but below that of the solvent Suitable infinitely miscible solvents include paraffin oil, chloroparaffins, ethyl or octyl silicate and tricresyl phosphate. Residual chlorosilanes remaining in solution after the bulk has been driven off by heating are released by stripping the solvent with a portion of the effluent gas from which the chlorosilanes have been removed. The stripped solvent and chlorosilane-containing gas which result are then recycled to the absorption stage. The process is particularly applicable to gas mixtures with a relatively low content of chlorosilanes, e.g. those in which the mole raio SiCl 4 :H 2  is 1:2 to 1:50, but preferably 1:2 to 1:4.
