Title: Improvements in or relating to water-in-oil emulsion mimeograph inks
IPC: C09D11/02
Filed: 1957-05-20
Abstract: 834,311. Inks. SIDDIQUI, S., and ASLAM, M. May 20, 1957, No. 15950/57. Class 146(3) A water-in-oil emulsion mimeograph ink containing 40-42% water is prepared by dispersing a pigment in a mineral oil vehicle, a drier and a stabilizer for the pigment dispersion comprising a rosin-oil complex, and adding an emulsifier which is an aqueous solution of glycerol, cane sugar or molasses. There are specified (1) pigments-Carbon black, ultramarine and organic coloured pigments, (2) vehiclemineral oils of 250-390 C.S. viscosity at 30‹C., (3) driers-lead or cobalt naphthenates or resinates. The stabilizer is obtained by heating rosin with litharge and a mineral oil of viscosity 130-135 C.S. at 280-290‹C., until the resulting mass, after being mixed with an equal volume of the mineral oil acquires a viscosity of about 400 C.S. at 30‹C. In an example the stabilizer is prepared by heating 60 g. rosin and 300 g. mineral oil of 130-135 C.S. viscosity to 240‹C. 7.5 g litharge are then added when this has reacted 6 g. cobalt acetate to form a drier in the stabilizer. The temperature of the mass is raised to 280-290‹C. until the viscosity of the product when mixed with an equal volume of the mineral oil reaches 400 C.S. 225 g. of the stabilizer thus obtained is mixed with 130 g. carbon black and with 575 g. of a mixture of mineral oils having viscosities of 250 C.S. and 390 C.S. respectively. The mixture is milled until a fine dispersion is obtained and then 55 cc. glycerol dissolved in 1000 cc. water is gradually added and milling continued for 4-8 hours.

Title: Improvements in and relating to biscuit and like cutting and embossing machines
IPC: A21C11/10
Filed: 1935-06-01
Abstract: 457,662. Biscuit &c. cutting and embossing machines. BAKER, G. R., and BAKER PERKINS, Ltd., Westwood Works, Peterborough. June 1, 1935, No. 15994. [Class 87 (ii)] A biscuit and like cutting and embossing machine is adapted for use with three different types of cutting and embossing units and for this purpose an auxiliary cross-head is provided which is resiliently mounted upon the main cross-head. As shown in Figs. 1 and 2, the main cross-head 12 is provided with arms 14 through the ends of which slide stop pins 15 fixed to two auxiliary cross-heads 16 which are held up to the main head by springs 18. The ends of the pins 15 are connected by crossbars 15a. Each cross-head 16 is provided with a pair of plungers 19 slidable in recesses 20 and pressed upwards by springs 21, and between the plungers there are slotted lugs 24 adjustable in slots 25. When a unit of the type described in Specifications 259,903 and 276,391, [both in Class 87 (ii)], is used, it is attached to the main cross-head 12 by bolts 33 and the auxiliary heads are inoperative. The main cross-head mechanism acts through shoes 29 to lower the embossers relatively to the cutters periodically. When a cutting and embossing unit as shown in Fig. 4, which is normally operated by two separate cross-heads, is used, the cutter frame 39 is attached by yokes 36 and bolts 33 to the main cross-head 12 and the embosser plates 31 are attached by bars 38 and connecting shackles to the plungers 19. The shoes 29 are longer than for the above units so as to clear the nuts 30. Stops are placed under the bars 15a to limit the downward movement of the auxiliary cross-heads 16. When a cutting unit as shown in Fig. 7 is used, the cutter frame 48 is attached by yokes 37 and bolts 33 to the main cross-head 12 and a back plate 45 carrying a stripper plate is attached by yokes 46 and stirrups to the slotted lugs 24. The shoes 29 are inoperative and may be removed ; stops are placed under the bars 15a as above.

Title: Improvements in or relating to hydraulic transmission
IPC: F16H61/46
Filed: 1966-04-12
Abstract: 1,139,198. Hydrostatic transmissions. SPERRY RAND CORP. 12 April, 1966 [12 April, 1965], No. 16012/66. Headings F2C and F2D. A hydrostatic transmission for accelerating and decelerating a heavy load, such as the rotating cab of a lift crane, at a uniform rate, comprises a variable stroke swash-plate pump 10 driving a constant displacement motor 16, the pump swash-plate 28 being adjusted by servo means controlled by a valve 82 which is moved in correspondence with the movement of a manual control lever 80 and which is also moved by a servomotor 78 subject to the differential pressure in the transmission supply and return lines which tends to restore the valve to its neutral position. The swash-plate 28 is adjusted by pistons 38, 36, the piston 36 being twice the area of piston 38. Piston 38 is subject to the pressure generated by an auxiliary pump 54, which pressure is also applied to the piston 36 via the valve 82 which has a metering land 84 smaller than a control port 96 leading to the piston 36. In the neutral position of valve 82 the liquid entering its supply port 94 will flow to its exhaust port 98 undergoing a pressure drop as it passes over the land 84 so that the pressure applied to piston 36 is half that applied to piston 38 to balance the forces applied to the swash-plate. The valve 82 is coupled to an intermediate point of a lever 126, one end of which is linked to the manual control lever 80, and the other end of which is connected to a double-acting servo piston 106 which is centred by springs and which is subject to the pressures in the transmission lines 24, 26. Pivoting control lever 80 to the left or right of its neutral position shifts the valve 82 to right or left of its neutral position to decrease or increase the pressure applied to piston 36 and thus shift the swash-plate 28 clockwise or anticlockwise. Fluid is supplied to the motor 16 through line 26 or 24, the inertia of the load creating a higher pressure in this line than in the return line 24 or 26, which differential pressure is applied to the servo 78. At a differential pressure which depends upon the degree of movement of the manual lever 80, the servo piston 106 is shifted sufficiently to restore the valve 82 to its neutral position, and the pump swash-plate 28 is maintained in the position which it has attained. As the motor speeds up the supply pressure 26 or 24 drops, the servo piston 106 shifts to the right or left and valve 82 is moved to the right or left to increase the angle of the swash plate, thereby accelerating the motor at a uniform rate. On returning the manual lever 80 to its neutral position the motor is decelerated uniformly by the action of the servomotor 78. A more rapid deceleration is obtainable if the lever 80 is moved to the other side of its neutral position so that the motor 16 acts as a pump and drives the pump 10, the servo 78 again functioning to give a uniform deceleration.

Title: A machine for removing the cartridges of nuclear reactor fuel elements
Inventor: ALLES MAURICE
IPC: G21C19/36
Filed: 1961-05-03
Abstract: 928,834. Removing canning from nuclear fuel. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 3, 1961 [May 3, 1960], No. 16026/61. Class 39 (4). [Also in Group XXII] A machine for removing the sheath 2 of a fuel element 4 comprises a structure 8 in which the element is supported by a guide 7, one end of the element being engaged by the thrust rod 6 of an hydraulic jack 5 mounted on the structure 8. Two cutting wheels 3 on the structure 8 symmetrically disposed around the sheath cut the sheath as it is advanced by the jack. In order to peel the cut sheath 2 away the rod 1 of fissile material the leading end of the rod abuts fingers 9 pivoted by links 10, 11 to supports 12 whereby as the rod is advanced the thrust on the fingers causes them to move apart against the bias of springs 13 and the cut portions of the sheath are bent away from the rod. Eventually, the rod passes between the fingers (Fig. 5, not shown). In modifications, not shown, the wheels 3 may be mounted on (a) ball and socket joints, (b) constant pressure hydraulic jacks, or (c) eccentric adjustable axes.

Title: Flying shear
IPC: B23D36/00
Filed: 1955-06-03
Abstract: 782,710. Automatic speed control systems. UNITED STATES STEEL CORPORATION. June 3, 1955 [Jan. 26, 1955], No. 16047/55. Class 38 (4). In a flying shear the relative speed of electric motors respectively driving the material to be cut and the cutters is maintained constant by automatically maintaining a fixed ratio between the voltages of separate generators supplying the motors, the drive to the cutters involving elliptical gearing associated with flywheels. In Fig. 1, steel strip S, fed by rolls 2 driven through gearing 10 by an electric motor 6, is cut into lengths by shears 4 driven through gearing 28 and 36 by an electric motor 26. Gearing 36 is elliptical and is associated with flywheels 50, 62 and 64 to even the load on motor 26. To maintain constant the relative speed of motors 6 and 26 and thereby obtain a constant length of cut strip, motor 6 is arranged to rotate the stator 100 of a potentiometer through gearing 68, shaft 70 and a synchronous electrical transmission 76, while motor 26 is arranged to rotate the arm 90 of the potentiometer through shaft 80, synchronous electrical transmission 84 and a clutch 92. Relative speed variations thus adjust the potentiometer and unbalance a bridge circuit formed with resistors 104, 106 so as to energize a field winding 108F of a generator 108 which excites a generator 122 to buck or boost the voltage applied from a generator 66 to motor 26 and thereby automatically correct the relative speed by adjustment of the speed of motor 26. The desired value of relative speed and hence length of strip is set by a handle 130 adjusting the ratio of gearing 68 and the excitation of generator 66 by differential potentiometers 158, 160 acting through an exciter generator 124. Strip length is indicated by a pointer 154 which is associated with handle 130 and co-operates with four scales corresponding to four selectable ratios of gearing 28. Handle 130 also adjusts the ratio of gearing 18 between a flywheel 20 and motor 6 so as to maintain a match between the kinetic energies of the drives to rolls 2 and shears 4. Part of the excitation of generator 124 is derived from a generator 22 supplying motor 6 so that if the rate of feed is varied by manual control of the excitation of generator 22, the speed of motor 26 is varied in a similar manner. U.S.A. Specification 2,180,202 is referred to.
