Title: Improvements in or connected with change speed gear
IPC: F16H61/02
Filed: 1920-10-26
Abstract: 154,572. Krupp Akt.-Ges., F. Nov. 24, 1919, [Convention date]. Variable-speed epicyclic gearing comprises two trains having some elements joined and is adapted to be operated by a sliding internally toothed element such as G, Fig. 1, so as to yield a solid drive and two reduced speeds. Stepped sun gears a', a<2> fast on a driving-shaft A mesh with planet gears E, D separately mounted in a cage C secured to a driven shaft B. The element G has teeth of double width so as to engage the gears D, E simultaneously. In this configuration, the gearing is locked and turns solid. When the ring G is slid upwards of Fig. 1, recesses g<2> upon it are engaged by snugs f<6> on a fixed casing F, and the gears E become disengaged; the gears D roll round on the fixed ring G yielding a middle speed. The slow speed is produced in like manner when the ring G is locked by snugs f<7>, and engages the gears E only. The changes are effected by sliding a non-revoluble and lockable ring H outside the casing F. In a modification, the solid drive is produced when the internal ring engages simultaneously the planet gears of one train and teeth on the cage. In another arrangement shown in Fig. 5, stepped planet gears N, N<1> carried by a cage M fast upon the driven shaft L mesh with a single sun gear k<1> upon the driving- shaft K. This is operated by a sliding internal ring 0 of double width similar to the ring G of Fig. 1. The ring 0 entrains with the gears N' through a floating ring P having internal and external teeth.

Title: Control of hydraulically or pneumatically operated equipment
IPC: F15B21/08
Filed: 1963-07-31
Abstract: 1,055,983. Coke oven regenerators. HEINRICH KOPPERS G.m.b.H. July 31, 1963 [July 31, 1962], No. 30286/63. Heading F4K. [Also in Division F1] A control system, Fig. 1 (not shown), for a plurality of sequentially operated hydraulic or pneumatic reciprocating motors 1, 2, 3, 18, 19 arranged to operate the fuel gas, waste gas and air valves of a regenerative coke oven each has an associated control valve 15, 16, 17, 20, 21 operated in sequence by a motor-driven rotary control device, and includes means responsive to a shortage of fuel gas which is operable to position or arrest the control device in a position corresponding with a chosen condition of the motors. The fuel gas shortage causes the closure of contacts forming part of a gas pressure recorder and the circuit completed thereby is arranged by suitable control of the motor driving the rotary control device to cause the device to stop in a position corresponding to closure of all the fuel gas valves. The control device preferably comprises a drum having electrical contact segments arranged to cooperate with wipers to thereby sequentially energize and de-energize magnetizing windings A-K to operate the motor control valves. Further contacts on the control drum operate in conjunction with the gas shortage contacts to ensure that the drum is returned, arrested or advanced to the safety position. In a modification, Fig. 3 (not shown), the control device is in the form of a pair of cam-shafts adapted to mechanically actuate the control valves. Each control valve has two end positions and an intermediate position and is supplied with pressure fluid through a line 38 by an electrically driven pump 33 or in an emergency by an accumulator 35 on manual pump 37. If the operation of a motor is not successfully completed before the rotary control device is about to initiate the operation of the next motor, the non-operation of a limit switch 44 associated with the motor causes the rotation of the control device to be arrested until the motor has completed its operation.

Title: Esters and functional fluids containing the same
IPC: C07C29/09
Filed: 1956-10-05
Abstract: Hydraulic fluids, heat transfer fluids or synthetic lubricants comprise a diester of a saturated aliphatic, saturated cycloaliphatic or aromatic dicarboxylic acid having up to eleven carbon atoms in the molecule and one or two monohydric primary alcohols, which alcohols are free from aliphatic unsaturation, have from five to sixteen carbon atoms and have a quaternary carbon atom in the betaposition, together with a silicate, a hexaalkoxy disiloxane, a silicone, a phosphate ester or a mineral oil base.  The diesters may comprise a major or a minor proportion of the mixture.ALSO:The invention comprises a diester of a saturated aliphatic, saturated cycloaliphatic or aromatic dicarboxylic acid having up to eleven carbon atoms in the molecule and one or two monohydric primary alcohols, which alcohols are free from aliphatic unsaturation, have from five to sixteen carbon atoms and have a quaternary carbon atom in the beta-position.  A preferred class of alcohols are those of the formula R1.C(R2)(R3).CH2.OH, in which R1, R2 and R3 are all alkyl groups, preferably n-alkyl groups. Another preferred group of alcohols is that in which the beta-carbon atom is part of a cycloalkyl group containing five or six carbon atoms. The compounds may be prepared by the usual esterification procedures, e.g. by heating the acid or acid halide with a slight excess of the alcohol using sulphuric acid as an esterification catalyst, and removing water azeotropically by distilling in the presence of toluene.  An alternative procedure involves ester interchange using an ester of the dicarboxylic acid with an alcohol of low molecular weight, such as methanol, in the presence of a catalyst.  The esters find use in hydraulic fluids, heat transfer fluids or synthetic lubricants (see Group III). Detailed examples of the preparation of diesters are given.  One example also describes the preparation of 2,2,4-trimethyl-1-pentanol by reacting 2,2,4-trimethyl-1,3-pentanediol with acetyl chloride to form 2,2,4-trimethyl-1,3-diacetoxypentane, selectively pyrolysing the latter to form 2,2,4-trimethyl-3-penten-1-yl-acetate, and then reducing the acetate using hydrogen with a palladium on carbon catalyst to form the 2,2,4-trimethyl-1-pentanol.

Abstract: 1,088,832. Grinding. ALLEGHENY LUDLUM STEEL CORPORATION. Aug. 4, 1964 [July 16, 1963], No. 30484/64. Addition to 1,038,065. Heading B3D. Surfacing apparatus similar to that in Specification 1,038,065 is controlled by bridge circuit systems each including first and second potentiometers in its opposite legs, the movable top of one potentiometer being manually adjustable and the movable top of the other potentiometer being moved in response to movement of a machine part. The control device 264-1 comprises a core 266-1 of rectangular hysteresis loop material having input windings 268-1, 270-1 and output winding 262-1. Input winding 268-1 is connected across leads 162, 173 adapted for connection (through AUTOMATIC switch 160 and contacts 175 respectively) to input terminals 148, 150; the voltage across the winding, as determined by variable resistor 274-1, is such as to induce flux in the core just beneath its saturation level. Input winding 270-1 is connected between the movable top of a manually adjustable rheostat 272-1 located at the operator's control console and the movable top of a potentiometer 34-P mechanically linked to one, 34, of the wheels on which the carriage moves, the linkage incorporating gear reducing means such that the potentiometer top moves throughout its range only when the wheel 34 has rotated through a number of revolutions sufficient to traverse the carriage 19 along its full path of travel. Rheostat 272-1 and potentiometer 34-P comprise a bridge circuit arrangement energized from leads 162, 173, the ouput of the bridge circuit appearing across input winding 270-1. When the bridge circuit is unbalanced, the voltage across input winding 270-1 results in saturation of the core, no voltage is induced in output winding 262-1 and a relay RS-1 remains de-energized. When the bridge circuit is balanced, there is no voltage across input winding 270-1 and a voltage is induced across output winding 262-1 to energize relay RS-1. In setting-up, the grinding wheel is located at the right-hand edge of the workpiece and rheostat 272-1 is adjusted to balance the bridge as indicated by lamp 278-1. In operation, each time the grinding wheel arrives at this edge, relay RS-1 is energized to reverse the travel of carriage 19. Relay RS-2 for reversing the travel at the other end of the stroke is controlled by a similar device 264-2 including manually adjustable rheostat 272-2 located at its operator's control console. Relay RS-3 for stopping grinding when the grinding wheel reaches the outer long edge of the workpiece is controlled by a similar device 264-3 including manually adjustable rheostat 272-3 located at the operator's control console and a potentiometer 58-P mechanically linked to the column 40.

Title: Photographic surveillance method and apparatus
IPC: G07G3/00
Filed: 1972-07-01
Abstract: 1367239 Checking cash register operation COMSEC CORP 1 July 1972 30920/72 Heading G4T [Also in Division G2] Each time a particular cash register operation is effected, it causes a camera to photograph both the part of the register at which amounts entered and totals are displayed and also the goods located on a counter in the region of the register and whose values should have been entered into the register. The particular cash register operations triggering the camera may be (i) sub-totalling, (ii) the entry of each and every amount and the subsequent sub-totalling or (iii) the entry of only the first amount and the final sub-totalling. For achieving these three modes of operation, circuit diagrams (Figs. 7-9, not shown) of a control device connected between the cash register and the camera are described. Electric signals derived from the appropriate cash register component are used to trigger the camera after a certain time period, imposed by a delay circuit, ensuring that the amount is actually displayed by the cash register before exposing the section of film. The camera may be a standard motion picture camera modified (Figs. 4-5, not shown) to expose only one frame for each actuation of the control device. In addition to the control device actuation, the camera may be actuated to expose one frame in response to the manual closing of a switch, for example for test purposes, and may also be actuated to operate in the conventional motion picture fashion by manually closing another switch, for example in the event of a burglary. Instead of being actuated by electric signals derived from the particular cash register operation, the camera may be actuated by a light signal (Fig. 10, not shown); a ray of light emitted by a lamp, incorporated in the camera, is reflected back to a photo-cell, also incorporated in the camera, by a particular flag having a reflective surface when such flag appears in the cash register display window. Opening of the cash register drawer, as opposed to cash register key depression, may be used to trigger the camera.
