Title: Improvements in Computerized Control Systems
IPC: G05B11/32
Filed: 1966-06-16
Abstract: 1,155,432. Refrigerating. ROBERTSHAW CONTROLS CO. 16 June, 1966 [16 June, 1965], No. 26984/66. Heading F4H. [Also in Division G3] The heating and cooling systems for a building complex are controlled by a known digital computer having a stored programme. Temperatures at selected points of each system, Figs. 1, 2 (not shown), are sensed by thermocouples and compared by the computer with stored predetermined values and the necessary control actions are initiated by digital signals which, through a multiplexer, actuate digital stepping motors positioning the mechanical controls of a system. As shown for a cooling system, Fig. 3, output signals 1P1S from the computer are used to control liquid cooling units 1-3 connected, in series-parallel, to air cooling heat exchangers AHI-AHL which are connected in parallel. The cooling units are identical and unit 1 comprises an evaporator 96 and condenser 100 through which the coolant is circulated by a compressor 98. The condenser is cooled by the water flow through a cooling tower 109 which is circulated by a pump 106. The coolant flow in the evaporator 96 is determined by a vane control 94 positioned, through a pneumatic diaphragm arrangement 88, by a ball-valve 74 positioned by a digital stepping motor 50. The stepping motor 50 is controlled through a transfer network and contacts 42, 46, actuated by alternately energized relay coils 34, 36 responsive to computer output signals 1P1S 3-6. Input signals 1P1S 1-2 control the energization of a motor 98M for the compressor 98, signals 1P1S T1-2 control the tower 109 and 1P1S P1-4 control a motor 106M for pump 106 and a motor 110M for pump 110 in the circulating line to the heat-exchangers AH1-AHL. The monitoring input signals comprise a positional feedback signal 1P1FS from a potentiometer 1PT1 coupled to the stepping motor 50, signals 1KM1-3 from the pump compressors and representing their power consumption; signals 1FM1-3FM1 representative of the flow rate through the cooling units 1-3, signals 1CTS1-3CTS2 representative of the inlet and outlet temperatures of the cooling units, and a signal CRS representative of the common return temperature which are derived to evaluate the temperatures across the cooling units; input signals 1SI-1SL are derived from temperature sensing devices associated with the heat-exchangers AH1-AHL. It is stated that the computer controls the start-up and close-down of a cooling unit and optimizes the operation of the units in dependence on demand. A read-out console is stated to record the efficiencies of the systems.
Patent GB-372676-A (GB)
Title: Talking and moving advertising figure with repeating sound record
IPC: G09F19/08
Filed: 1931-09-28
Abstract: 372,676. Moving signs. KEPES, M., 3, Kossuth tÚr, WEISS, H., 4, Rakoczi U, and BURGER, J., 55, Kotaji U, all in Nyiregyhaza, Hungary. Sept. 28, 1931. No. 26994. [Class 3 (i).] A moving and speaking advertising figure o<1> is actuated by a driving cord n from a pulley p on the table spindle of a gramophone b, clockwork c being provided to start and stop the gramophone intermittently. A repeating device for transferring the needle back to the beginning of the record after each rendering consists of a spiral arm d hinged to a base 5 fixed to the record and normally held up to clear the sound-box f by a spring 2. A guide groove d<1> extends along the arm d and round the base 5 to meet the last spiral on the record. The needle entering this groove d<1> is transferred over the record to the first record spiral, the pressure of the sound-box f forcing down the arm d against the spring 2 during its transfer. The clockwork control mechanism consists of a rotated disc m formed on one side with a cam y interrupted at z. A pivoted arm l bears against the cam y, or drops into the gap z, and through linkage k, j controls a switch, when the gramophone is electrically driven, or a brake shoe i. The disc m is removable and reversible to bring into action a differently disposed cam on its other face, or for its substitution by a disc having pins, circumferentially disposed, on each face, giving two more timing arrangements. The bearing t for the part i is adjustable to control the braking effect. When an electric sound-box is employed a loud-speaker is fitted in the figure o<1>. The records employed have silent intervals in the grooves so disposed that the needle is in a silent portion when the gramophone stops and starts, thus allowing reproduction speed to be attained on starting before an effective part of the groove is reached.

Patent GB-1021849-A (GB)
Title: Gas tempered glass sheets
IPC: C03C17/00
Filed: 1963-07-10
Abstract: <PICT:1021849/C1/1> <PICT:1021849/C1/2> A gas-tempered glass sheet having a thickness of between 0.088 and 0.135 inch and of a uniform composition throughout has a centre tension of at least 3200 millimicrons per inch (6,800 lb./in.2).  The strain pattern is one which shows up under polarized light as a series of spaced bands of varying light intensity extending across the sheet unidirectionally (Fig. 14, not shown), and the ratio of the surface compressive stress to the central tensile stress is greater than 2.3: 1 but less than 3: 1. This type of pattern can be demonstrated by immersing an edge surface for about twenty minutes in a lithium nitrate-potassium nitrate eutectic at 250 DEG  C. followed by washing and then etching with a 5% solution of hydrofluoric acid (Fig. 15, not shown).  A soda-lime-silica glass sheet so tempered is found to have 50,000 to 500,000 nuclei of birefringent crystals per cm.2 of glass surface, and also one major face the sodium oxide content of which for a depth of 0.5 to 5 microns is only 10 to 50% of that of the rest of the sheet.  To achieve this temper a glass sheet is advanced along rollers 20 between upper and lower radiant heaters 17 to a heating zone 2. This zone comprises a flat bed 30 of modules 31, arranged at an angle (not 90 degrees) to the direction of travel of the sheet, each module having a stem which opens into a plenum chamber 33. The plenum 33 is fed with hot gas which flows through each module at a pressure of 0.25 p.s.i.g. and 1200 DEG  F. to heat the glass sheet and at the same time form a gas cushion upon which the sheet is supported.  To prevent pressure build-up exhaust ducts 39 are fitted intermittently into the bed and extend through chamber 33. The sheet is driven by disc-like members 37 engaging one edge of the sheets, the whole bed being transversely tilted at an angle of 5 degrees to the horizontal to maintain the sheet in contact with the discs.  The sheet then passes to a quenching section 3 which is also built up of a flat bed of modules 80 of a similar arrangement to the heating section.  Each module 81 has a long stem 82 which projects through a water-cooling box into a plenum 84 Cooling air at 100 DEG  F. and 1.4 p.s.i.g. flows through the stems 82 out of each module, thus cooling the heated sheet, but at the same time forming a cushion support, the cooling air flowing away through exhaust ducts 78 and through the cooling boxes.  The glass sheet is driven through this zone by discs 370.  The modules forming the quenching zone are designed to obtain the maximum heat exchange and also to give a good turbulent flow and provide a uniform supporting pressure, see Figs. 9-13 (not shown). The bed 80 has a mirror image just above the glass sheet.  To enable the sheet to be quickly transferred from the heating zone to the quenching zone, there is a sensing device designed to actuate a timer operating a two-speed driving mechanism.

Abstract: 965, 600. Focusing viewfinders for cameras. AGFA A.G. July 16, 1962 [July 25, 1961], No. 27299/62. Heading G2A. An optical component for incorporation in a camera viewfinder includes a'focusing screen incorporating as a focusing aid over part of its area a surface having projecting from it individual prisms or refracting elements, each of which presents a refracting apex or edge, the prisms or elements being so close together and so small that they are not clearly distinguishable by the naked eye, and also includes beyond the focusing screen margin a lens or like optical element for producing in the viewfinder an image additional to the finder image. As shown a viewfinder screen, e.g. in a reflex camera, which may have plane or curved surfaces, is provided with a focusing aid 2 in the form of a pattern of small prisms integrally formed with optical elements 4 which are preferably coloured or rendered opaque to define clearly the limits 6 of the viewfinder field as seen through the field lens 3. An area of one of these elements may be left clear so that a diaphragm aperture or other scale 5 may be viewed in focus together with the finder image. Extensions 7 of the elements 4 may support other optical members such as the field lens 3 which may bear optional frame marks 8. The elements 4 may contain luminescent material to provide a bright frame or the marks 8 may be caused to form a reflected frame as in an Albada finder.

Title: Process for the manufacture of vinyl chloride
IPC: C07C17/08
Filed: 1957-08-30
Abstract: In a process for the manufacture of vinyl chloride acetylene is reacted in the presence of a catalyst known to be suitable for the addition of hydrogen chloride to acetylene with a gaseous mixture consisting substantially of hydrogen chloride and chlorinated alkanes in the vapour state.  Mixtures of hydrogen chloride and low boiling chloralkanes such as methyl or ethyl chloride or mixtures of tetra chlorethylene, carbon tetrachloride and hydrogen chloride obtained by chlorinating methane at high temperatures or similar mixtures obtained by simultaneously chlorinating and partially cracking ethane and propane may be employed in the process.  Catalysts specified include mercury chloride or vanadate, compounds of bismuth, antimony, barium, strontium, calcium, magnesium vanadium zinc or iron such as the chlorides or mixtures thereof, e.g. mixtures of mercury chloride with alkali metal chlorides or activated carbon.  Dissolved catalysts may be employed, e.g., cuprous or mercury chloride to which one or more compounds of metals of Group II-V or VII, e.g. compounds of zinc, cadmium, manganese, antimony or bismuth.  An apparatus for carrying out the process is described with reference to a Figure (not shown).  In examples: Vinyl chloride, carbon tetrachloride and some chloroform are obtained by reacting gaseous chlorine and methane, passing the reactor mixture with further methane through a reactor to eliminate traces of free chlorine and obtain a mixture of carbon tetrachloride and hydrogen chloride with some chloroform and methane and reacting such mixture with acetylene in the presence of active carbon impregnated with aqueous mercury chloride (1); and in a similar process a mixture of vinyl chloride, carbon tetrachloride tetrachlorethylene and hexachlorethane is obtained by heating a mixture of chlorine, propane, carbon tetrachloride and tetrachlorethylene, passing the products over heated active carbon, mixing the products with acetylene and reacting the mixture in the presence of active carbon impregnated with aqueous mercury chloride (2).  The compounds of the reaction products may be obtained by fractionation.  Specification 349,017 is referred to.

Abstract: 975,822. Endless conveyers. SIEMENSSCHUCKERTWERKE A.G. July 28, 1961 [Nov. 5, 1960], No. 27467/61. Heading B8A. The state of occupation of an endless conveyer belt 11 by articles 12 is reproduced by signals 15 recorded on a magnetic tape 13 which runs in synchronism with the belt 11. The tape 13 operates in conjunction with semi-conductors of the kind which are responsive to magnetic fields e.g. Hall generators. When an article is fed from a feed conveyer 1 to the belt 11, a recording head B1 is caused to record a signal 15 on the tape 13. Similar heads B2-B8 operate in conjunction with feed conveyers 2-8. If a receiving station for delivery from the belt 11 to a delivery conveyer 3 is not in a position of readiness, a holding head S3 stops the conveyer 11. Monitoring heads F2, F2<SP>1</SP> determine whether a gap is available on the conveyer 11 to permit the delivery of an article from the conveyer 2 to the belt 11. The tape 13 may be carried on a wheel (not shown) which is coupled to the conveyer by an electric reduction drive 14.

Title: Demodulation of Digital Data Signals of the Type using Angle Modulation of a Carrier Wave
IPC: H04L27/233
Filed: 1967-06-14
Abstract: 1,172,270. Digital transmission systems. COMPAGNIE FRANCAISE THOMPSON HOUSTON-HOTCHKISS BRANDT. 14 June, 1967 [17 June, 1966], No. 27529/67. Heading H4P. A system for demodulating frequency or phase shift binary signals comprises means for sampling the signals at n times the bit rate, corresponding amplitude samples in adjacent bit psriods being added and the results of successive additions being continuously totalized over a preset number of samples, and means for producing from the total a binary signal representing the transmitted data. In a first embodiment, Fig. 2, received differentially-coded phase shift signals having one cycle per bit are sampled 8 times per bit. The samples are quantized to eight levels at 14, giving a 3-bit parallel signal and a sign bit. The four bits pass direct and via delay 22 to adder 18. The delay has a duration of one input bit so the adder adds the amplitudes of corresponding samples in adjacent bits. The sum passes direct and via another one-bit delay 32 to totalizer 28, which thus forms a running total of the amplitude samples over a 16-sample period. The totalizer feeds unit 34 which provides a step waveform representing the total and from this waveform unit 36 develops the binary data transmitted. In a modification for demodulating phase shift signals having an odd number of quarter cycles per bit two sampling units and quantizers are used, the received signals passing direct to one sampling unit and through a 90 degrees phase shifter to the other. A similar circuit is used for the reception of frequency shift signals. In this instance the phase shifter affects only one of the received frequencies. It is stated that the system may dispense with the quantizers, the system then operating in continuously variable rather than digital manner.
