Filed: 1948-12-02
Abstract: 652,027. Hydromechanical change-speed gear. GENERAL MOTORS CORPORATION Dec. 2, 1948, No. 31191. Convention date, Dec. 6, 1947. [Class 80(ii)] A two-train planetarygear fluid-coupling combination, providing an all-fluid drive in first, second and reverse ratios and a branched torque-sharing fluidmechanical drive in third and fourth (direct) comprises an input train having a ring-gear 5 directly driven by the engineflywheel 1 through a spring-coupling S ; a reaction sun 10 which can be held by a band-brake B or clutched at A to its output planet-carrier 7 which thus imparts reduced or direct drive to the impeller I of the fluid-coupling, the runner R of which is fast on an inner shaft 20 integrally carrying one sun 21 of an output train which has intermeshing short and long planets 22, 23 carried by the final output shaft 50 and respectively meshing the sun 21 and a second sun 27 which can be held by a brakeband D or clutched at C to an intermediate sleeve 11 on which is fast to the fluid-coupling impeller I. First and second speeds are obtained with the second sun 27 of the output train held by the brake D and the input train driving its first sun 21 through the fluid-coupling in either reduced or direct-drive by applying separately the brake B and clutch A, all torque passing through the fluid-coupling. Third and fourth speeds are obtained by releasing the output 'train brake D and applying the clutch C; third being by applying the brake B to drive the first sun 21 of the output train in reduced drive through the input train and fluid-coupling ; and at the same time mechanically driving the second sun 27 directly through the intermediate sleeve 11, now also driven in reduced drive through the input train, whilst in directdrive fourth all brakes are released and both clutches C, A are engaged, whereby the two output suns 21, 27 receive direct drive through the fluid-coupling and mechanical paths respectively. Reverse is by applying a band-brake E to a ring-gear 28 meshing the long planets 23, all the clutches and other brakes being released. A wedge-type one-way brake 90 is also provided for the input-gear reaction-sun 10 and, if free-wheeling in first and third speeds is not objectionable, this brake may be used to eliminate the band-brake B. The brakes and clutches are applied by oil-pressure provided by input and output driven gear-pumps P, Q, and controlled by valves 70 operated by an output driven governor 67. The brake-bands are applied by pistons having stepped diameters to which pressure can be applied differentially or together. The reverse brake E may alternatively be mechanically operated. Thrust washers 81, 82 &c. accurately space the parts.

Title: Control system for positioning workpieces
IPC: G05B19/40
Filed: 1973-07-02
Abstract: 1429888 Automatic control of speed L SCHULER GmbH 2 July 1973 [1 July 1972] 31487/73 Heading G3N A control system for positioning a workpiece includes a counter responsive to movement of the workpiece, means responsive to a predetermined count to provide a first signal which causes a second electrical signal, proportional to the square root of the value of the first signal, to be produced for controlling the speed of the motor driving the workpiece. In the arrangement shown the workpiece is driven by a stepping motor, either electric or electro-hydraulic, in accordance with the pulse output from the voltage to frequency converter. In operation a 'desired value' from decade switches, punch cards or tape, is put into the step counter and is then counted down as the motor drives the workpiece. When a predetermined count is reached the counter interrogation enables the D/A converter which transmits a voltage proportional to the count to the square rooting device to provide a signal proportional to the square root of this voltage which is integrated in the run-up transducer and supplies the voltage to frequency converter to provide pulse signals to the stepping motor control.

Filed: 1937-11-16
Abstract: 511,593. Alloys. UDY, M. J. Nov. 16, 1937, No. 31534. Void. Convention date, Sept. 27, [Class 82(i)] Ferrochromium alloys to be used as sourcematerial in the production of chromium-iron alloys are made from chromite ore, advantageously high in iron or mixed with iron-oxide, or from chromiferous slags, by smelting in a submerged-arc electric furnace with added base (e.g. lime), silica, and carbon in such a proportion that all the iron and chromium and part of the added silica are reduced so that taking into consideration the proportions present of bases such as lime and magnesia and of aids such as silica and alumina a normal dibasic silicate slag, having a molecular base-acid oxygen ratio around 1: 1, is produced as a molten layer above the molten metal. The reacting materials should contain silica in excess of that required to maintain the ratio referred to and carbon in excess of that required to reduce the chromium and iron of the ore and the excess silica. In this way low grade chromite ores may be employed; when ores rich in chromium are employed a proportion of siliceous iron should be added. The reaction temperature is 1600- 1700‹C. Alloys containing iron with 30 per cent. of chromium, 6 per cent. of silica, 5 per cent. of carbon and with 24.3 per cent. of chromium, 4.34 per cent. of carbon, 5.1 per cent. of silicon are described.

Title: Programme changing in electronic data sorting
IPC: G06V30/224
Filed: 1961-09-01
Abstract: 943,301. Record sorting apparatus. SPERRY RAND CORPORATION. Sept. 1, 1961 [Dec. 7, 1960], No. 31567/61. Heading G4M. In apparatus for sorting cheques Fig. 1 according to transit numbers recorded in magnetic characters along the lower edge the numbers are read by a character reader 12 Fig. 2 and applied in turn to a converter 16. The numbers, in binary scale form are entered successively into shift registers in unit 22 until all eight are stored and applied in parallel to comparator 32 in which they are compared with numbers read out successively from a magnetic drum Fig. 3. Each number occupies an axial line the eight digits being represented each by four binary bits. Each number has associated with it sorting instructions consisting of four groups of two bits. There are four sorting pockets 0,1, 2, 3 and sorting requires four passes of the cheques, the four groups of two bits being selected successively. The number of each cheque should be recorded on the drum. When the numbers from the drum and buffer store 22 agree a pulse is applied to read out the sorting control bits and actuate one of the four deflector gates 23-26 to pass the cheque to the appropriate pocket. Read out owing to a spurious agreement as the cheque numbers are being entered into the store 22 is prevented by a gate 41 which is disabled during reading of the numbers by a multivibrator 47 which is set by a symbol 13 preceding the number and reset by a similar symbol after it. On the second, third and fourth passes switches are set in the block 34 to read out the appropriate sorting group. The data stored in any particular line of the drum can be changed by sending through a special change record Fig. 4 which is distinguished by a mark 51. When this mark is sensed the gates 52 are opened to pass the number sensed to store 54 and the read amplifiers of the magnetic drum are disabled to prevent any comparison being made. The line or "slot" number is also written on the cheque. In Fig. 4 it is 3000. As the drum revolves, pulses from a clock track are counted in the slot selector 58 and when the count reaches the slot number (3000) on the change record a pulse is sent via gate 53 to open gates 64 and pass the stored number and assignment numbers to the write heads to be recorded on the appropriate track of the drum. Specification 796, 579 is referred to.
