Title: Improvements relating to dye jiggers
IPC: D06B3/32
Filed: 1931-03-27
Abstract: <PICT:0369405/IV/1> <PICT:0369405/IV/2> The batch rollers a, b of dye jiggers are driven by two direct current electric motors g, h through spur gearing i, j, the armatures of the motors being arranged in series whereby an automatic speed-balancing action according to weight of roller is obtained, giving a substantially uniform cloth speed through the liquid.  The shaft of each of the rollers carries a one-way clutch of known type to prevent overrunning of the fabric. The motors are automatically reversed when one batch roller becomes full by means of switches 16, 17 controlled by electromagnetic coils 20, 21 connected with the main 18 through a lamp 23 and by leads 24, 25 with contacts 26, 27 with which can engage a contact blade 28 connected to a lead 29 which is connected by contact blades 30, 31 with the main 19.  The blade 28 normally engages the contact 26, but is moved away from it into contact with 27 by a cam 32 on an arm 33 which is moved to one side or the other by a lever t, which is itself moved by stops on a disc driven from the roller b.  When the rollers have reversed a predetermined number of times a cam 40 on a toothed wheel 42 connected with the lever t separates the contacts 30, 31 and breaks the circuit.

Title: A method of and apparatus for the continuous coating of metal strip with a thermosetting plastics composition
Inventor: PEARSON THOMAS FELIX
IPC: B05D1/18
Filed: 1962-03-12
Abstract: 1,029,822. Strip coating apparatus. ANSETT IRON CO. Ltd. March 11,1963 [March 12,1962], No. 9346/62. Heading D1L. [Also in Division B2] A method for the continuous coating of a metal strip with a thermosetting plastics material comprises passing the strip upwardly and once only through the free surface of a bath of liquid thermosetting plastics coating composition and heating the strip before and/or after its passage through the bath to effect curing of the plastics material around the strip. In the arrangement shown a coil 1 of steel strip 2 is mounted on spindle 3 and the free end is threaded between rollers 4 and then through an opening in bottom plate 10 of container 5 containing plastic coating composition 6. The strip then passes through a heating zone 7 and is coiled on drum 9. The opening in bottom plate 10 is closed by a pair of compressible pads 11 e.g. of felt, urged into contact with the strip by a pair of spring steel plates 12 supported on spaced rods 13 and adjustable by screws 14. The opening is preferably shaped to conform to the cross-section of the strip to be coated. The container 5 may be provided with a funnel for supplying coating composition to the container and for monitoring the level of the composition in the container. The thickness of coating may be adjusted by varying the speed of the strip, the viscosity of the composition or by preheating the strip or by mechanical means such as rollers or scrapers. The speed of the strip is also related to the curing requirements of the coating and the coated strip may be passed through patterning or embossing rollers before it is fully cured. The end of one coil may be welded to the beginning of the next to obtain a continuous feed of strip through the apparatus or in the case of rigid strips then may be fed individually through the apparatus.

Title: Improvements in or relating to hydraulic motors
IPC: B64C1/14
Filed: 1958-03-24
Abstract: 820,704. Hydraulic control systems. CURTISS-WRIGHT CORPORATION. March 24, 1958 [March 25, 1957], No. 9412/58. Class 69(2). A control system for one or more reciprocating motors is such that the pressure of the hydraulic fluid supply can vary over a wide range without adversely affecting the operation of the motors. The motors are supplied through a throttle valve from a main hydraulic system, and a reversing valve which is actuated by the rise in motor-operating pressure at the end of each stroke, is restrained from actuation until the motor-operating pressure has risen to near the pressure then existing in the main system. Motors 17, 18 for actuating aircraft windscreen wipers are supplied with liquid from the aircraft hydraulic system via a line 2, an adjustable throttle valve, a line 7 and a reversing valve 16 alternately to motor lines 11, 14, the exhaust side being open via a valve chamber 20 to a line 15. Reversing valve 16 is actuated, through a quick-throw arrangement, by a piston 10 subject to the pressures in the motor lines 11, 14. Balancing pistons 24, 25 are provided in chambers on opposite sides of the piston 10 and are urged inwardly by the pressure in the aircraft system applied via a shut-off valve and a line 3, the inner faces of the pistons being subject to the pressure in the associated end of the cylinder of piston 10. Operation.-When a manually operable stem 33 of a master control and metering valve 1 is raised, the first operation is to admit liquid past valve seating surfaces 31<SP>1</SP> to the line 3 to move pistons 24, 25 inwards to centralize the valve actuator piston 10. Further opening movement of stem 33 permits a floating plug 31 to engage a shoulder 32<SP>1</SP> and further upward movement opens a bore in the plug to give throttled flow to the line 7. As shown, liquid is supplied to the line 11 to move the motor pistons to the right, the piston 10 being prevented by piston 25 from moving the quickthrow mechanism past dead centre. When the motor pistons are arrested the pressure in line 11 rises, and when it almost equals the then existing supply system pressure it is sufficient to move the piston 10 to the right to reverse valve 16 and initiate another stroke. By slowly closing the master control valve 1 the wipers can be parked at either end of the stroke. The quick-throw mechanism is described in U.S.A. Specification 2,451,449.

Title: Improvements in or relating to ducting for electric conductors
Inventor: BISHOP GEOFFREY CHARLES
IPC: H02G3/06
Filed: 1949-04-07
Abstract: 660,919. Conduits. PANEL FITTINGS CO., Ltd. April 11, 1950 [April 7, 1949; Feb. 27, 1950], Nos. 9484/49 and 4950/50. Class 36. Lengths of ducting for electric conductors are joined together by a channel-member which, together with a backing plate, is telescoped into adjacent ends of two duct lengths, separating screws being passed through tapped holes in the channel member to engage with the surface of the backing-plate so as to separate these two parts and obtain frictional engagement between the channel member and the duct lengths. The ducts are preferably of rectangular crosssection and comprise base 5, side walls 3, 4 and flanges 1, 2. The channel member comprises side walls 6, 7 and a base 8 having the same area as backing plate 9, which is placed under the base 8 so that tapped holes 10, 11 therein register with tapped holes 16, 17 in the plate 9. Additional tapped holes 13, 14 are provided in the base 8. The channel member and backing plate are positioned in the ends of adjacent ducts and screws are inserted in the holes. These through-holes 13, 14 separate the plate 9 from the base 8, forming a tight frictional engagement between the channel member and the duct lengths. The screws passing through holes 10, 16 and 11, 17 press into the base 5 of the ducts and make electrical contact between the parts. In an alternative arrangement (Fig. 5), four contact screws 24, 25 and four separating screws 28, 29 are provided, two of each lying on either side of the butt joint 26 between adjacent duct lengths. The channel members may be of L, T or other shape to join duct lengths which do not lie in a straight line. The open side of the duct may be closed by a cover member carrying spring-clips which engage under the flanges 1, 2.

Title: Hydraulic cushion for die pads in presses
IPC: B21D24/02
Filed: 1964-03-07
Abstract: 1,017,655. Hydraulic shock-absorbers. F. M. WILLIAMSON. March 7, 1964, No. 9759/64. Heading F2S. [Also in Division G3] A mechanical press has a reciprocable ram 10 for pressing a work blank down on to a die pad 14 which is retractable toward a bolster 12 against the resistance of an hydraulic cushion. The latter comprises a piston 18 which co-operates with the die pad 14 and is slidably mounted in a cylinder 16 in the bolster 12 the cylinder being connected by lines 24, 26 and a valve unit 22 to a tank 20 of hydraulic fluid maintained at a pressure of 100 lbs. per square inch. During a closing movement of the press ram pressure rapidly builds up equally at both the upper and lower ends of a valve 30 so that a relatively weak spring 62, acting upon a piston extension 58 of the valve 30, is able to maintain the valve 30 closed against a seat 46. At a sufficiently high pressure the fluid trapped on the upper side of the valve 30 unseats a pilot valve 34 in a by-pass 80, 66, so that fluid can pass through passages 56, 48 to the tank 20. When the pilot valve 34 opens the pressure within the valve bore above the valve 30 is suddenly reduced due to a restricted passage 76 in the line 24, 56. The higher pressure now on the underside of the valve 30, shifts the latter to the open position so that fluid spills through passages 48, 26 to the tank 20. As the ram commences its upward stroke the superior pressure on the tank side of the valve 30 is applied, through lines 66, 72 to a spool-type control valve 32 to move it to its other position, the reduced pressure obtaining in the cylinder 16 being applied to the space 60 above the valve piston 68 and allowing the valve 30 to rise and the cylinder 16 to be re-charged with fluid. After the cylinder has been recharged a spring 71 returns the spool valve 32 to the position shown. In a modification, Figs. 2, 3, not shown, for delaying the recharging of the cylinder 16 until after the press ram has begun its upward stroke the passage 72, leading to the spool valve 32 is blocked by a further valve 102, until hydraulic fluid, having been supplied during a pressure stroke from the cylinder 16 to an end space in a bore 100 for the valve 102, can leak past a needle valve 132 to lowpressure lines. In alternative arrangements, the valve 102 can be operated, for the required period of time, by means of a solenoid or by pneumatic means.

In a magnetic tape store, data is recorded on the tape in coded form, and a logic circuit is provided for reading the stored data, and producing a predetermined signal code in response to the logic circuit output, which is subsequently recorded on the tape. The coded data comprises a plurality of digits each recorded on a different one of a number of tracks. In order to erase certain items of data, the logic circuit 30, Fig. 1 is arranged to produce an output whenever such data is presented at magnetic heads, e.g. 20, associated with each track. As described, the logic circuit is an OR circuit, and produces an output whenever the data on the tape is not 000. This output triggers monostable circuit 36 to its unstable state to open AND gate 34 and enable the write means 16 whenever a command signal is produced in register 42. The command signal also enables a signal generator 44 which feeds an erase signal (111) to the write means. The output from the logic circuit 30 is also used to trigger a further monostable circuit 37 which controls a verify circuit 51 to check that the correct erase signal has been written on to the tape.
