Title: Web cutting control system
IPC: B23D36/00
Filed: 1975-06-05
Abstract: 1516893 Automatic control of web cutting RENGO KK and NIPPON RIRAIANSU K K 5 June 1975 [7 June 1974 16 Aug 1974] 24322/75 Heading G3N A continuously moving web is cut by cutters 3 into fixed lengths or on sensed marks by controlling the speed of the cutters so that it equals the speed of the web at the cutting instant. The speed of the cutter driving motor 6 is detected by tachogenerator 7 and its position by transducer PG B  and the distance of travel of the web is detected by transducer PG A . A photo-electric sensor OPA detects pre-printed marks on the web and the sensor OPc by detecting the passage of the cutting blade produces a cutting complete signal. Sensor OP B  again detects the arrival of the tips of a cutting blade to produce a distance discrimination signal. The control shown in Fig. 6 operates by comprising the pre-set cutting length signal LA, which is set to the actual size required or to the distance between the printed mark and the cutting complete sensor position, with the pre-set value B o  which represents the circumference of the cutter. These values together with the sensor outputs and cutting mode switch PP input to interface I 1  cause the various gates to operate to give fixed position or long size, i.e. >1 1 +1 3 , or short size, i.e. <1 1 +1 3  cutting. The gates are operated by signals from the input discriminating circuit H o  which responds to the various sensor signals to provide combinations of signals α 1 -α 4  as shown. The web flow detection circuit 18 generates pulses corresponding to the fed length from the two 90 degrees phase displaced pulse trains from transducer PGA which pulses are processed to give one pulse for each millimetre of travel. Similarly the pulses from the cutter rotation transducer PG B  are processed to provide the same scale for each pulse. In operation the cutters are accelerated until at the position of sensor OP B  their peripheral speed equals that of the web and a cut will occur at the correct place. When a cutting complete signal is received from sensor OP C  the cutter driving motor is stopped after a short delay and its position is stored in counter C 2 . In the short size cutting mode the cutters are continuously driven. The operaton of the apparatus when cutting on marks is claimed in Specification 1507600.

Title: Improvements in or relating to control valves for fluid pressure brakes
IPC: B60T15/04
Filed: 1938-08-20
Abstract: 518,288. Fluid-pressure brakes. BOSCH GES., -R., (formerly BOSCH AKT.-GES., R.). Aug. 20, 1938, No. 24566. Convention date, Aug. 23, 1937. [Class 103 (i)] In a control valve for fluid-pressure brakes, adjustment of the spring pressure acting on a manually axially displaceable valve operating member is effected by rotating the member to cause an abutment nut for the spring to travel along the member. Control valves 1, 2 for tractor and trailer vehicle brakes respectively are.operated by a common pedal operated lever 7 connected to the valve 1 by lever 9 and to the valve 2 by a rod 10 between which and 'the axially displaceable member 12 is a spring 11. A spring 18 abutting on a nut 15 urges a piston 34 carrying a tubular part 37 normally to the position shown lifting the valve 38 from the seat 40 so that compressed air from the reservoir is normally supplied to the trailer cylinder to release the brake. Operation of the pedal 8 to apply the brakes, moves the member 12 to the left, permitting the valve 38 to seat and withdrawing the part 37 from the valve to allow compressed air to escape through this part and passages 17, 17<1> to apply the brake. If the pedal and lever 7 are held in an intermediate position the fall of the cylinder pressure acting on the piston 34 enables the spring 18 to return the member 12 comprising the spring 11 and permitting the part 37 to engage the valve to stop the cylinder exhaust. To adjust the pressure of the spring 18, a pin 20 is removed to allow the member 12 to be turned by a collar 21 causing the nut 15, rotation of which is prevented by engagement of a pin 16 in the passage 17, to travel along the member. Alternative operating means for the valve comprises an arm 23 connected by a cord 25 to the hand-brake lever and adapted when turned to be moved axially by balls 31 seated in sockets having inclined or cam surfaces, between the boss of the arm and a disc 28 on the casing. Lateral movement of the arm moves the member 12 through the collar 21. The lever 23 and disc 28 are caused to follow the pedal operated movement of the member 12 by the action of springs 33 on pins 32.

A fluidic, remotely controlled apparatus for steering a parachute comprises at least one control unit 20 housing a piston 21 which is connected to a rod 27 placed in a solenoid 28 and which carries passages 22, 23 and a well 24, a tube 19 connecting said control unit to a cylinder 14 open-ended at 15 and housing a piston 17 attached to a control line 18 linked to at least one steering control (not shown). A pressurized gas supply 26 is connected to well 24 via valve 25 and control actuating means for valve 20 comprises a master switch 32, a power pack 31, an aerial 30, a radio receiver 29 and switches 35. In the operating position shown, gas passes from bottle 26 via valve 25 into well 24 and enters cylinder 14 via passage 22 and tube 19 so forcing piston 17 to move down cylinder 14 to cause control line 18 to operate control flaps (not shown). Control is exercised by a signal via aerial 30 which promotes energization of solenoid 28 to move rod 27 so that passage 22 is disconnected from tube 19 and gas supply 26. Air pressure acting on control flaps (not shown) withdraws piston 17 into cylinder 14 to closed end 16 so that the control flaps (not shown) may return to their normal position. Control unit 20 may also operate a further control line through passage 23 and tube 37.
