Title: Improvements in or relating to the production of planographic printing plates
IPC: B41N3/08
Filed: 1951-10-09
Abstract: 766,532. Printing surfaces. TICKNER, A., (Columbia Ribbon & Carbon Manufacturing Co., Inc.). Oct. 9, 1951, No. 23502/51. Class 100(2) Preliminary preparation of planographic plates: A planographic printing plate is prepared by forming a masking film around the image consisting of an insoluble compound of carboxymethyl cellulose. The plate may consist of metal, plastic, or paper provided it is of sufficient wet strength when processed and sufficiently ink receptive. The masking film is applied after the plate has received the image. Any ink may be used provided is is repellant to the masking film. The film is preferably applied immediately or shortly before prints are to be made from the plate. The plate is coated with. an aqueous solution of a salt e.g. sodium and aluminium, of a carboxymethyl either of cellulose, to which an insolubilizing reagent is added, e.g. hydrochloric, sulphuric, or phosphoric acids or citric, tartaric, or tannic acids, so that the film which forms on the plate becomes permanently water insoluble. The film when dry forms a hydrophilic coating. In an alternative method the insolubilizing agent is initially omitted and the aqueous solution of a salt of a carboxymethyl either of cellulose is applied to the plate and dried. The film may subsequently be rendered insoluble by including in the wetting or fountain solution used when printing a precipitant salt such as aluminium sulphate and/or the insolubilizing reagent. The image may be typewritten on the plate prior to application of the masking film. The method may also be used to duplicate sheets already printed by using these as plates, after suitable treatment, and then applying the masking film.

Title: Improvements relating to digital self-check apparatus
IPC: G06F11/00
Filed: 1970-05-18
Abstract: 1,272,145. Digital recording/playback device. PICKER CORP. 18 May, 1970 [26 June, 1969], No. 23882/70. Heading G4C.  The invention relates to a self check device for monitoring the number of bits in a word. Data in the form of a predetermined number of positive and negative pulses 14, 16 situated between synch pulses 18 is fed on line 12 to a " 1 " separator, a " 0 " separator and a synch separator arranged to supply only " 1", " 0 " and synch pulses respectively. The " 1 " pulses are inverted and with the " 0 " pulses are fed to an adder feeding shift pulses to a shift register 26 and to the trigger inputs of a ring counter. The " 1 " and " 0 " pulses are shifted along the shift register and the ring counter is advanced under control of the adder. When a predetermined number of bits have been counted the 0 output of stage 10F and the 0 output of stage 10G of the ring counter are both " 1 " and feed a NAND gate 34 coupled to a NOR gate 36 which, with an output from the synch separator feeds an AND gate 40. If the correct number of pulses are received signals from the NOR gate and the synch separator coincide and the AND gate is enabled. If an incorrect number of bits are recorded or read the signals do not coincide and gate 40 is inhibited. Data may be recorded magnetically using a return-to-zero method. During read-out of a sequence of identical digits some may be dropped on playback. The shift register may be read out in parallel. The shift register and ring counter may be reset by a signal from a computer on lines 42, 44.

Title: Improvements in or relating to starters for internal-combustion engines
IPC: E21D15/502
Filed: 1933-08-29
Abstract: 417,278. Turning - gear. STEINER, G., 6, Scherestrasse, Solothurn, Switzerland. Aug. 29, 1933, No. 23930. Convention date, Aug. 29, 1932. [Class 7 (v).] In an electric starter, a pinion b rigidly mounted on a shaft a is initially displaced axially by a plunger i into partial engagement with an engine gear r, the starting motor is then switched on, and the pinion is displaced into full engagement with the gear r by a steep-thread connection between the pinion shaft a and a sleeve d rigidly mounted in the hollow armature shaft c of the motor. The plunger i may be the armature of an electromagnet h, and acts through a spring l on a pin m carrying a leaf spring n in engagement with a pin o abutting against the end of the shaft a. When the pinion b is partly in mesh with the engine gear r, the starting motor is switched on by a switch member k carried by the armature i. On the completion of the engagement of the pinion, the spring n rides over the inclined surface s of a recess in the bush h, out of engagement with the pin o, so that the pinion and its shaft a are free to be retracted by the threaded connection d and springs f, g on the starting of the engine. In a modification, the axial displacement of the plunger i is effected by a pedal.

Abstract: 666,930. Gas turbine plant. DOWTY EQUIPMENT, Ltd., and HARDING, J. K., (formerly KAMMERER, J. H.). Sept. 15, 1950. [Sept. 16, 1949] No. 23945/49. Class 110(iii) [Also in Group XXIX] A liquid-fuel supply system for an aircraft gas-turbine engine and of the kind comprising a pump (not shown) having an inlet 13 and an outlet 14 connected at 15 to a conduit having a variable throttle and leading to the burners, a piston-actuated byepass valve 25 controlling a byepass between the outlet and inlet of the pump, a restricted passage 29, 30 from the pump outlet to the outer face of the piston 23 which actuates the valve 25, and a passage 31 having a vent valve (not shown) controlled by means responsive to any suitable engine-controlling variable is characterized in that the byepass valve is slidable in its housing without spring bias and in that the byepass between the pump outlet and the valve 25 has a spring-closed valve 33. The valve 33 allows, when the engine is being started, a delivery pressure to be generated sufficient to close the byepass valve by action on the outer face of the piston 23 before delivery pressure is admitted, through passages 18, 19, 27, to the inner face of the piston. The valve 33 unseats before the engine attains a selfrunning condition and remains open until the engine passes below its idling speed. The connection to the burners may be taken from between the valve 33 and the byepass valve instead of from the point shown.

Title: Improvements in and relating to mechanisms for limiting the feed motion in a lathe or other machine tool
IPC: B23B47/18
Filed: 1946-08-13
Abstract: 631,949. Lathe &c. details. SKODA WORKS, PLZEN. Aug. 13, 1946, No. 23968. Convention. date, Feb. 23. Addition to 631,947. [Class 83 (iii)] The feed limiting mechanism of the parent Specification is modified in that a second control drum is provided which rotates at a slower speed than the first control drum and cooperates therewith to enable a longer traverse to be obtained without re-setting the mechanism. A stop drum 60 with a number of discs 31 having stop projections 32 are set in their required positions by a clamping nut 33. Levers 68 with stop-ends 48 are held away from the stops by first and second control drums 61, 62, respectively, on which projections 47 on the levers bear. These control drums consist of discs similar to the stop drum, but having recesses 42 and 63, respectively, in the discs. The control drums are driven by reduction gearing from the stop drum. When recesses in the two control drums come together into the position shown in Fig. 1, the appropriate lever falls and engages a corresponding stop on the stop drum to halt the carriage feed. Vernier discs are provided on the drum shafts to indicate the positions at which the carriage will stop. A latch member 71 may be turned by hand to render selected levers inoperative, or this member may be connected to rotate with a turret head when the invention is applied to a turret lathe.

Title: Improvements in and relating to servo steering mechanisms for motor vehicles
IPC: F15B9/08
Filed: 1945-09-17
Abstract: 608,236. Fluid-pressure servomotor-control systems. BAGHUIS, L. H. Sept. 17, 1945, No. 24006. Convention date, March 27, 1942. [Class 135] A servo-steering mechanism for motor vehicles comprising a piston and cylinder, one of which is stationary and the other is locked against rotation, but is capable of axial movement; a screw spindle and nut, one of which is attached without play to the rectilinearly displaceable element of the piston and cylinder combination and the other is mounted for rotation and restricted axial movement in such manner that it is capable of rotating through a predetermined angle before causing displacement of the rectilinearly displaceable element; and valves co-operating with stationary seats to control the supply and discharge of fluid to and from the cylinder spaces and to limit the axial movement of the rotatable element, the valves being moved towards and away from their seats by and during the axial displacements of the rotatable element. In an embodiment, a steering shaft 8 is connected to a screw spindle 5 through the intermediary of bevel gears 9. Spindle 5 works in a complementary nut 2 constituting the piston of the servomotor, the piston carrying a key 4 to prevent it rotating. Rotation of shaft 8 causes spindle 5 to move axially and so actuate, through a friction coupling 26, a lift valve 25 to apply pressure fluid from an inlet 23 to the left-hand side of piston 2 via pipe 24, or to the right-hand side of the piston via pipe 17, chamber 12 and pipe 15. The side of the piston to which pressure fluid is not applied will be connected to exhaust via shuttle valve 19, 20, chamber 13 and passage 21 formed in the spindle 5. The consequent movement of piston 2 will actuate the road wheels through shaft 3 and will also move spindle 5 to provide a follow-up connection by recentring the various valves. Should the steering-wheel be released, a spring 28 will return all parts to a central or neutral position. In a modification, valve 25 is replaced by a valve similar to valves 19, 20 and carried directly by the spindle, and the steering-wheel is also fixed directly on the spindle.

Abstract: 615,829. Liquid storage tanks; relief valves. DUBOIS, L. J. Aug. 13, 1946, No. 24014. Convention date, Oct. 2, 1942. Addition to 615,828. [Classes 69 (i) and 135] [Also in Group XXVIII] A spheroidal tank for storing liquids is supported both at the base d and in the region of the central horizontal zone by a belt c, which in turn is supported on an extension e<1> of the base d by resilient supports l. During construction, the tank is subjected by hydraulic means to an internal pressure equal to or in excess of the normal working pressure and the upper portion b is then encased with a coating of concrete m to which it is keyed by hooked members. Tanks of this type are so arranged in groups that if the pressure in any one tank becomes excessive the tank is vented into an adjacent tank at a lower pressure. Each valve allowing flow between the tanks comprises two spring-loaded pistons s<3>, s' which, depending on the pressure exerted on them, expose one or other of two ports s<0> which lead to passages S<10>. To facilitate decanting of the contents of the tank, the gas pressure within the tank may be increased and the shell of the tank may be heat insulated.

Title: Electrodynamic braking systems for electric motors
IPC: H02P3/12
Filed: 1949-09-19
Abstract: 677,441. Control of D.C. motors. TELEMECANIQUE ELECTRIQUE. Sept. 19, 1949. [Oct. 7, 1948] No. 24082/49. Class 38 (iii). When a reversing controller is moved to a forward-running position, contactors AV and L are energized, together with a relay F which closes contact F<SP>1</SP> and opens contact F, the motor starting with its armature shunted by resistors RF<SP>1</SP>, RF<SP>2</SP>. Further movement of the controller opens contact SH to disconnect the armature shunt circuit, contacts D<SP>1</SP>, D<SP>2</SP>, D<SP>3</SP>, then being closed in sequence to remove armature resistors R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>. Return of the controller to the "off" position disconnects the motor from the line and completes a braking circuit through contacts AV, F, and SH. The energization of reversing contactor coil AV and relay coil F<SP>2</SP> is maintained by the dynamic operation of the motor. At about a quarter of the line voltage contact F<SP>2</SP> closes to remove resistor RF<SP>2</SP> from the braking circuit, the contactor AV releasing at about a tenth of the line voltage when the motor is practically stationary. The contacts F, F<SP>1</SP>, operate so that there is no interruption of exciting current. Braking as described will take place in the event of supply voltage failure, the relays F and SH. being adjusted to release at about half the normal supply voltage.
