Title: Improvements in capacitance type temperature control
Inventor: WEBER VICTOR
IPC: G05D23/275
Filed: 1958-12-11
Abstract: 880,415. Automatic temperature-control systems. ROBERTSHAW-FULTON CONTROLS CO. Dec.11, 1958 [Dec. 16, 1957], No. 40024/58. Class 38 (4). [Also in Group XXXVI] In a system for controlling the temperature in a space, the feedback from anode to grid of a triode oscillator valve 12 is determined by a temperature-responsive capacitor 56 (see Group XXXVI), connected to a resonant circuit. A transformer 32 is fed from an alternating current supply 36 via a timer actuated switch 34. Secondaries 44, 50 of the transformer supply the valve through a relay coil 46 and a choke 49. Feedback from the anode of the valve to a resonant grid circuit, comprising a reactance 20 and capacitors 30. 56, 58, 60, 64, is applied through a capacitor 22. The grid to cathode excitation of the valve is derived between a junction of capacitors 30, 64 and capacitor 60 and a tapping on the reactance 20. The capacitance of the temperature-responsive capacitor 56 is increased with reduction in temperature and at a predetermined temperature, set by the vernier sensitivity control capacitor 58, the triode valve 12 ceases to oscillate on the positive half-cycles of the supply, so that the directcurrent component of the anode current rises to a value at which the relay coil 46 operates a switch 55, connecting a space-heater 68 to a supply 72, and changing over indicator lights 52 by a switch 54. In an alternative mode of operation, a manual switch 26 is closed to connect the anode of the valve 12 to earth via a capacitor 24, a linked switch 27 being opened to disconnect the feedback path through the capacitor 22. The choke 49 is short-circuited by a switch 47. Reduction in temperature causes oscillations to occur on the positive half-cycle of the supply, de-energizing the relay coil 46. Switch 55 then connects a heater 84 to a supply 88. A bi-metal thermostat 76 controls the heater 68 when the switch 34 disconnects the transformer 32 from the supply 36. Alternating- current bias at supply frequency is applied to the valve 12 through a potential divider comprising resistors 66, 28. In a modification, an exterior positioned temperature - responsive capacitor and a humidity-responsive capacitor are connected in parallel with the capacitor 56 to apply a compensation to the control point of the system. U.S.A. Specification 2,943,488 is referred to.

Abstract: 1,004,088. Rotary engines and compressors. BAYERISCHE MOTOREN WERKE A.G. Nov. 8, 1961 [Nov. 9, 1960], No. 40027/61. Heading F1F. A rotary compressor or internal combustion engine includes a triangular piston 1 rotating inside a two-lobed housing 3, and packing elements 2 of which the curvature of the surfaces engaging the inner surface of the housing varies so that the region where the greatest wear occurs has the greatest radius of curvature. The variation in curvature in the direction of rotation may be from a minimum to a maximum (as shown) or from a maximum to a minimum and to a maximum (Fig. 4, not shown) or from a minimum to a maximum to a minimum. Fig. 2 shows a packing element whose rubbing surface 2 is an involute of a circle centred on M. The points I and II define the limits of contact, and are so chosen that the tangents t 1 , t 2  to the circle are tangents to the ring gear 4 fixed to the piston. The surface 2<SP>1</SP> may comprise arcuate portions of varying radius (Fig. 3, not shown) or may comprise two involutes (Fig. 4, not shown). The packing elements may be of L-section (see left-hand side of Fig. 1) to reduce weight. The elements are also preferably inclined to the piston axes of symmetry so that where the pressure difference across an element changes sign, for example, at O<SP>1</SP> in the case of an internal combustion engine, the sides 7<SP>1</SP> of the element are normal to the tangent To<SP>1</SP> at the point of contact.

Abstract: 1400160 Numerically controlled machine tools TOYODA KOKI KK 30 Aug 1972 [9 Sept 1971] 40215/72 Heading G3N In a numerical control system in which a computer (10), Fig.1 (not shown), receiving control data via teletype (12), a magnetic disc store (11) being provided, controls a plurality (15, 16, 17) of machine tools, the machine control apparatus (18, 19, 20), for each machine stores interpolation data, calculated in and derived from the computer, to increase the number of machines that can be controlled. Machine control apparatus, Fig.2 i) Contouring operation N-bit shift registers 60, 70, 80, for the X, Y, Z axes receive data, processed for interpolation directly, one N-bit word at a time, from computer (10), in response to data demand signal CC, the register for the axis requiring the largest movement for the word comprising entirely ones. The desired end point of the contouring operation is fed in co-ordinate form directly to subtracting counters 66, 76, 86. Upon entry of the words into the registers, a data shift finish signal sets flip-flop 46 enabling, via AND 45 receiving also a signal from contouring register 36, the passage of shifting pulses to counters 60, 70, 80 whose frequency is defined by a binary signal F from computer (10), decoded and processed in voltage/frequency converter 43, the words in registers 60, 70, 80 being read out via AND's 61, 71, 81 and OR's 62, 72, 82 to the pulse motor drive units 67, 77, 87, the direction of drive-for each co-ordinate being defined by signals selectively fed to AND's 68, 69; 78, 79; 88, 89 receiving direction signals from registers 30-35, the subtracting counters are counted down by the pulses from OR's 62, 72, 82. When counter 47 attains the count N, indicating that registers 60, 70, 80 have been cleared, flip-flop 46 disenables AND 45 and an interpolation demand signal to the computer (10) initiates a fresh reading of interpolation data words into the registers, the above process being repeated. Each subtracting counter, on reaching the count zero, emits a "1" to AND 50, so that when 50 is enabled to emit the CC signal, the contour operation is completed. Figs. 3 and 4 (not shown) illustrate linear contouring in two dimensions, circular contouring being also possible. ii) Point-to-Point operation. A point-to-point signal P, from register 37, replaces signal C, and, the desired end point having been fed to subtraction counters 66, 76, 86, AND 44 is enabled, so that all clock pulses from converter 43 are passed via AND's 63, 73, 83, enabled for either set coordinate direction for each axis. to the drive units 67, 77, 87. When any axis subtraction counter reaches the count zero the signal to AND 50 is also fed via the corresponding inverter 64, 74, 84 to disenable the corresponding AND 63, 73, 83, stopping pulse feed to the corresponding drive. Signal CC, when all subtraction counters reach zero, indicates completion of the point-to-point operation.

Title: Lubricating oil compositions
IPC: C10M169/00
Filed: 1958-12-15
Abstract: Oil-soluble complexes formed between (a) an oil-soluble aliphatic polycarboxylic acid, (b) a fatty acid having at least 8 carbon atoms and (c) an aliphatic amine having at least 8 carbon atoms, are employed as lubricating oil additives (see Group III). Component (a) of the complex may be oxalic acid, an alkane dicarboxylic acid, citric acid or tartaric acid, while component (c) may be a primary, secondary or tertiary, saturated or unsaturated aliphatic mono-amine or an N-alkyl polyamine (e.g. an N-alkyl diamine such as an N-alkyl trimethylene diamine).  The complex may be formed by reaction between the components at a temperature below 85 DEG C. preferably in the presence of a non-polar solvent (e.g. a hydrocarbon such as benzene or a light mineral lubricating oil).  it is essential that no water or amides are formed during the formation of the complex.  In the examples, component (a) is oxalic, succinic, adipic, sebacic, azelaic, citric or tartaric acid, component (b) is lauric, stearic or oleic acid and component (c) is hexadecylamine, octadecylamine, lauryl dimethyl amine, octadecyl dimethylamine, 1,1,3,3,5,5,7,7-octamethyloctylamine or a mixture of tert-alkyl primary amines containing 12-15 or 18-24 carbon atoms in the molecule.  Specification 689,872 is referred to.ALSO:A composition, suitable for lubrication under severe operating conditions such as extreme pressures and high temperatures, comprises a major proportion of a hydrocarbon lubricating oil and a minor proportion of an oil-soluble complex of (a) an oil-insoluble aliphatic polycarboxylic acid, (b) a fatty acid having at least 8 carbon atoms and (c) an aliphatic amine having at least 8 carbon atoms.  Component (a) of the complex may be oxalic acid, an alkane dicarboxylic acid, citric acid or tartaric acid, while component (c) may be a primary, secondary or tertiary saturated or unsaturated aliphatic mono-amine or an N-alkyl polyamine (e.g. an N-alkyl diamine such as an N - alkyl trimethylene diamine).  The lubricating oil may be mineral oil or a synthetic hydrocarbon oil such as a polymerized olefin, an alkylated aromatic or an isomerized wax.  The composition may contain a clarifier (e.g. an alkanol) to ensure good dispersion of the complex in the oil. Other ingredients which may be present in the composition are silicone anti-foaming agents, alkylphenol anti-oxidants and polyacrylate ester viscosity-index improvers. In the examples, mineral lubricating oil compositions are described containing complexes derived from (i) adipic acid, lauric acid and either a mixture of tert.-alkyl primary amines containing 12-15 carbon atoms in the molecule (amine A1) or lauryl dimethyl amine, or (ii) d-tartaric or sebacic acid, laurie acid and amine A1 (the d-tartaric acid complex being employed in conjunction with 2-propanol as clarifier).  For comparison purposes, mineral oil compositions are described containing (iii) adipic, sebacic or tartaric acid and amine A1 or lauryl dimethyl amine or (iv) the reaction product of amine A1 and lauric acid.

Abstract: 1446686 Alpha-numeric displays and circuits therefor NCR CORP 17 Sept 1974 [26 Oct 1973] 40434/74 Heading G5C [Also in Division G3] Apparatus for displaying a number of digits sequentially and in significant order on a single digit display device 49, e.g. of l.e.d. type, comprises means for blanking the display between individual digits for a period greater than one eighth of a second, the digits each being displayed for between one eighth and one half of a second. A clock or watch is described in which six sequentially displayed digits give the time in hours, minutes and seconds. Timing signals are derived from a 60 c/s. source 1 and fed to the display by a specified dividing and coding I.C. 44 and logic inverters 45-48. The coded signals for the six digits are multiplexed at 1000 c/s. The circuit 44 also produces one of six signals to designate which digit is currently available at the coded outputs, the six signal outputs being connected via inverters 50-55 to NAND gates 56-61. The NAND gate outputs are all connected to a 4-bit latch circuit input of the display 49, this circuit preventing the introduction of new information to the display except when a strobe pulse is present at its input. The other inputs of the NAND gates 56-61 are connected via inverters 63-68 to selected ones of sixteen outputs #T0-#T15 which are sequentially energized for about  second each. This energization is achieved by the use of NAND gates 26-41 which have four inputs fed via inverters 10-25 and 43 with signals derived from the source 1 by sequential binary dividers 2-9. The six digits are thus displayed in order, commencing with the tens of hours. Blanking between digits is achieved by connecting the remaining ones of the outputs #T0-#T15 to a NOR gate 62 the output of which is taken to a blanking input of the display 49. The display is thus blank for one time period T1 between the hours digits, for two periods T3, T4 between the hours and minutes, and similarly for the minutes and seconds. Finally there are three blank periods T13-T15 before the cycle recommences. Switches 69-71 allow the hours and minutes to be advanced rapidly for setting, or the internal time count to be held. The source 1 may be a relaxation oscillator or a crystal oscillator with dividers, or may be coupled to a mains line. Different lengths of the various blanking periods are envisaged for other applications, e.g. to display social security or telephone numbers in, e.g., two and/or three digit bursts.

Punched data from a card fed to a read station, reversed and aligned to read the first column and then successive columns is entered into a first recirculating memory. A second recirculating memory contains a bit for each column of the card, the first bit representing the location in the first memory of the data to be entered. As each card column is read the bits in the second memory are successively erased. The second memory also contains an instruction in a specific column position stopping processing of the card when that column is reached. At this point data printed on the card and representing the previously read columns is situated in a position in which it can be read by an operator. This data is then manually entered into a third recirculating memory and compared with corresponding data in the first memory. If all columns agree the remaining columns are read and compared and the card is punched with a verification marking. If an error occurs the data is re-checked and the data in the first memory is re-written. After all columns have been checked and corrected further processing cannot be continued until a blank card has been punched with the corrected data in the first memory. Timing diagrams and control circuits for the reading, checking and verifying are given.
