Filed: 1944-10-13
Abstract: 591,789. Rolling screw threads. REED, A. B. Oct. 13, 1944, No. 19806. Addition to 590,075. [Class 83 (iv)] In a thread-rolling machine in which the work blank is held axially immovable between and rotated by driven die rolls while the entire thread length is rolled, the rolls being moved progressively and equally through a cycle to and from the work axis, the power mechanism includes a replaceable cam which causes the dies to penetrate the work progressively during more than one die revolution in a cycle of approach, penetration and release. As shown, the work blank 10 has threads rolled in its surface by parallel or tilted dies 11, 12, 13, Fig. 2, each mounted on an arbor 14, Fig. 1, carried by the spaced arms 15, 16 of a yoke 17 which interfits with a pivot block 20 mating with a block 22 ; the arbors are guided by pivoted links 24. The blocks 22 are secured to stress rings 32, 33, carried by a supporting ring 34 which is oscillated to effect radial movement of the dies to and from the work by means of a replaceable cam 40 engaging a roller 46 carried between spring-influenced levers 47 connected by a link 50 to a block 52 on the ring 34. The stress rings 32, 33 have three cam faces 110 to which the blocks 22 can be clamped in adjusted positions and one of the rings may be turned relatively to the other, by means of a hand-operated pinion 112, to tilt the blocks for rolling tapered threads. The means for securing the blocks to the rings, and the rings to each other, consist of lugs 120 on the blocks and a draw bolt 121 pivoted thereto and passing outwards to the outer ring 34 to which it is secured by a screw 122. Each block is furnished with grooves in which metal strips 124 are seated, the strips bearing against the cam faces 110. The driving gear comprises a main shaft 63 on which are two gears driving horizontal shafts 67, 71 through replaceable gears 65, 66, 70. The shaft 67 drives the cam 40 through reduction gear 68, 69 and a clutch 43, 45, and the dies are driven from the shaft 71 through reducing gear 73, 74, pinions 76, 78 and universal couplings 80 ... 83. For small work one of the dies is replaced by a support, the other two dies being disposed at an angle of 120-180 degrees. In a further modification, only one die is moved to and from the centre.

Title: Improvements relating to apparatus for reproducing images in colour
IPC: H04N9/20
Filed: 1956-06-28
Abstract: 836,015. Colour television. GENERAL ELECTRIC CO. June 28, 1956 [July 1, 1955], No. 20063/56. Class 40 (3). [Also in Group XL (c)] Relates to colour television cathode-ray tube image-reproducing apparatus in which colourdifference signals 32, 34, 38 are applied to one set of electrodes of the tube guns, e.g. control grids 26, 28, 30, and the luminance signal Y is applied to the other set, i.e. cathodes 16, 18, 22, via a potential distribution network 4, 6, adjusted for colour balance whereby different fractional amounts of the Y signal are applied to the respective guns in accordance with the relative gun and phosphor efficiencies. In accordance with the invention, the master brightness control potential, which is derived from a potentiometer 50, is applied to the guns via the same potential distribution network 4, 6 so that the colour balance is maintained irrespective of the brightness setting. In a first modification, Fig. 2 (not shown), the circuit is similar but is rearranged so that the luminance signal is applied to the grids and the colour-difference signals to the cathodes. In a second modification, Fig. 3 (not shown), potentiometers 4 and 6 forming the distribution network are connected in parallel. The invention is applicable to apparatus incorporating either a single threegun tube or three separate single-gun tubes.

Title: Photochemical reaction method and apparatus
IPC: B01J19/12
Filed: 1962-05-24
Abstract: In the preparation of cyclo-alkanone oximes by the action of a nitrosation agent on a cycloalkane contained in a tank 1 wherein the reaction mixture is irradiated by a light source 2, the reaction mixture is shielded from heat rays by circulating a coolant, such as water, air or nitrogen, in a transparent jacket 3 surrounding the light source, a transparent baffle tube 4 being arranged in the jacket so that the coolant, which is introduced through inlet 5, first flows in direct heat exchange with the reaction mixture and subsequently flows through a path which is nearer the light source but where there is no heat exchange with the reaction mixture.  The <PICT:0980518/C2/1> coolant finally leaves the apparatus through outlet 7.  In an example, cyclohexanone oxime hydrochloride is produced by reacting cyclohexane with a gaseous mixture of nitrosyl chloride and hydrogen chloride under the influence of a high-pressure mercury lamp, the temperature of the reaction liquid being maintained at 15 DEG  C.  Another example relates to the production of cyclo-octanone oxime hydrochloride by reacting cyclo-octane with a mixture of dinitrogen tetroxide, chlorine and hydrogen chloride. A third example described the production of cyclododecanone oxime hydrochloride.  Nitrosation agents referred to, other than those mentioned above, are nitrosyl sulphuric acid; and a mixture of nitrogen monoxide and chlorine.

Title: Anti-skid device for a wheeled vehicle full power braking system
IPC: B60T8/173
Filed: 1970-04-27
Abstract: 1278892 Hydraulic anti-skid braking systems; valves BENDIX CORP 27 April 1970 [13 May 1969] 20143/70 Headings F2F and F2V A full-power hydraulic anti-skid braking system for a wheel 20 of a vehicle includes comparators 36, 40, 42 for generating electrical error signals when acceleration (positive or negative) of the braked wheel 20 attains predetermined reference levels G 1 , G 2 , G 3 , ramp generators 44-47 responsive to said error signals for generating an electric ramping signal and a valve 18 for controllably applying a braking force to a cylinder of the wheel 20 in proportional response to said ramping signal. The valve 18 has ports 18a, 18b, 18c and in normal braking a coil spring 97 biases a reaction plunger 95 to cause a ball valve 91 to move from a valve seat 92 to thereby establish communication between ports 18a and 18b and allow hydraulic flow to the wheel 20. In the event of a ramping signal indicative of undesired wheel acceleration being received by a solenoid 24 of valve 18, the reaction plunger 95 moves away from the ballvalve 91 to establish communication between ports 18b, 18c and relieve pressure at the wheel 20. As seen, communication between ports 18b, 18c will be stopped upon sufficient movement of reaction plunger 95. With ports 18b, 18c in communication, the fluid flows back to a reservoir 14 included in an hydraulic circuit which, as shown, also includes a pump 10 coupled to the vehicle drive or to an electric motor energized by the vehicle battery, an accumulator 12 and a three-way driver operated control valve 16 operable by a brake pedal. The electric ramping signal is given by summation of the individual signals of ramp generators 44-47 by a voltage summing network 54 and the signal is applied to solenoid 24 through an AND gate 56. If the driver terminates braking, a brake switch connected to the brake pedal generates a signal which causes a flip-flop 52 to set gate 56 to close to cause the disappearance of the voltage across winding 24. The circuit of Fig. 3 includes a memory means 38 including a memory capacitor, a memory comparator means and a one-shot triggered by the output of comparator 36. A sensor 26 senses the speed of wheel 20 and generates pulses which pulses are converted to a D.C. voltage in a counter 28 and this voltage is supplied to a threshold 30; at wheel speeds above a predetermined value the threshold 30 supplies a speed proportional signal to a derivative amplifier 32 which generates a signal proportional to wheel acceleration and applies this signal to the comparators 36, 40, 42.

Title: Hydraulic pump
IPC: F04B1/12
Filed: 1955-07-12
Abstract: 851,701. Swash-plate pumps. NEW PATENTS Ltd., SILBERSTEIN, V., and EASTES, J. C. Oct. 9, 1956 [July 12, 1935], No. 20159/55. Class 102(1). An hydraulic pump comprises a shaft 8, Fig. 1, on which are mounted two swash-plates 9, 10 arranged to reciprocate opposed pistons 13, 14 in cylinder blocks 2 and 3. The piston 13 has a wide annular groove 15 which registers in turn with inlet and outlet ports 16 and 17, so arranged that communication with one port ceases as communication with the other commences. The delivery of the pump is maintained at a predetermined constant by axial movement of the shaft 8 which varies the proportion of each revolution of the swashplate during which the groove 15 of piston 13 registers with the inlet and outlet 16, 17 respectively. The shaft 8 is biased by a spring 43 in a hollow differential piston 37 having one side 40 of smaller area than the other side 41, the two sides being connected by a bleed passage 42. The delivery from the outlet 17 is connected to the smaller side of 40 of the piston 37 and through passages 57 and 45, Fig. 2, to one side of a plunger 47 biased by a spring 50. The larger side 41 of the piston is connected to a port 54 in a cylinder member 60. Any decrease in the delivery pressure will cause a greater force to act on the large side 41 of the piston 37 to move the shaft to the right so that the groove 15 will communicate with outlet 17 for a larger tie up to a maximum where the groove 15 communicates with the inlet and outlet 16, 17 for equal times. Any increase in the delivery pressure above a predetermined valve will cause the plunger 47 to move to the left so that liquid from the large side 41 of the piston 37 will pass through port 54, a recess 53 of the plunger and port 52 to the pump inlet and thus the piston 37 and shaft 8 will move to the left. The delivery pressure is determined by the loading of spring 50 which is adjusted by nut 51. Lubrication is provided by grooves in the piston and pads 12 and passages 24, 25 leading to a groove 26.

Abstract: 1,079,515. Carrier telephone systems; radio signalling. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 14, 1965 [May 15, 1964], No. 20425/65. Headings H4L and H4R. In a carrier transmission system of limited capacity transmitting signals from equipments requiring different bandwidths for messages, e.g. telegraph, telephone, and facsimile equipment, the available bandwidth of the system is split up to cater for the demand at any one time the bandwidth of any one channel being changed to suit the demand, even e.g. during a call, and the billing rate is suitably adjusted with the change in bandwidth. In Fig. 3 a subscriber's station has a telephone 82, requiring a transmission bandwidth of 3000 cps., and a data transmitter 83, requiring a transmission bandwidth of 100 cps. The subscriber selects the system he wishes to use by operation of switch 86 which, in addition to connecting the appropriate transmitter to the line, transmits a signal from generator f1 or f2 to indicate to the exchange the channel bandwidth required. If the subscriber wishes to be connected to a second subscriber over the trunk network involving the carrier system he dials the required number and is connected via the switching circuit 98 in the normal way except that the rate of charging for the call is controlled according to the bandwidth required as indicated by the tone detector 100 in response to the signalling frequency, f1 or f2, transmitted from the subscriber over switch 86. In addition the tone signals operate switch 110 to select a channel of a bandwidth appropriate to the transmission, the tone signals being also transmitted to the distant terminal over the signal bypass 111 to control the allocation of channels appropriately. A change-over from one channel bandwidth to another may be made during a call by operation of switch 86 in which case signalling lamps 84 and 85 will indicate when the channel bandwidth has been changed and the tone detector will change the billing rate appropriately.
