Title: Coil transfer apparatus
IPC: B21C47/24
Filed: 1976-09-20
Abstract: 1525426 Handling coil springs; powered grippers MATHEWSON CORP 20 Sept 1976 [11 Dec 1975] 38882/76 Headings B8A and B8H The leading coil spring of a group thereof delivered on an endless conveyer is separated - from the remainder by a gripper 62 mounted on a carriage 66 shiftable to transfer the coil to a turntable 64 which rotates the coil to align a knot thereof at a predetermined position and the gripper is then rotated on the carriage to invert the coil and to release it in its inverted position. In the embodiment described the conveyer has upper and lower guides located at different sides of the conveying path and having coil engaging edges which converge in the conveying direction thus serving to align the knots of the coil and to partially separate the coils in the group (Fig. 2A, not shown). At the forward end of the conveyer is a sensor S1 which controls operation of the conveyer in dependence on whether a coil is located at a position to be gripped and a spring finger 160 which retains the succeeding coil on removal of the leading coil. The gripper 62 (see also Figs. 9 to 11, not reproduced) comprises a slotted block 78 carrying a pivotally mounted slotted plate 70. Initial engagement of the coil with the plate 70 actuates a sensor to cause pivoting of the plate by pneumatic means and entrapment of the coil within slot (72). Carriage (66) is shifted pneumatically and the lower end of the coil is moved up ramp 67 to turntable 64. After rotation of the turntable to align the knot as required the gripper assembly is rotated by means of rack 160 engaging a pinion on the assembly to place the inverted coil at a coil assembly station 16. A plurality of coil separating and orientating devices are arranged side by side (Fig. 2, not shown) and means are provided to prevent take up of the coils by the assembly machine until a full row of coils have been placed at the station 16.

Title: Control system for a variable displacement pump
IPC: F04B49/08
Filed: 1975-09-23
Abstract: 1522027 Reciprocating pumps ABEX CORP 23 Sept 1975 [16 Oct 1974] 39049/75 Heading F1A [Also in Divisions F2 and G3] A variable displacement pump has its rocker cam 34 connected to a pivoted vane servomotor in which chambers 80, 81 communicate with ports 98, 97 having a moving-seat follow-up relationship with an input port 134 in a manually-operated valve 118, the pressure of the fluid supplied to and exhausted from the servomotor being automatically limited to values dependent on the pressure supplied by a servo pump 52 and the pressure of the fluid delivered by the variable displacement pump being limited by means which override the manual control of the servomotor. Check-valves 107, 108 and restrictors 109, 110 restrict exhaust flow from the servomotor while allowing a high flow into it. Flow through the pump is reversible so that either port P1 or P2 may be the output port. When P1 is the delivery port, and fluid pressure is excessive, output pressure acts through lines 249, 255 and 256 on a pilot valve 247 which lifts and allows a valve 203 to lift and establish communication from a line 248 through a line 269 to the chamber 80 to reduce the pump output. A further valve 207 loaded through a line 212 by pressure from the servo pump 52 lifts if the flow from the valve 203 is more than twice servo pressure and allows the excess flow to pass into a circuit 230 communicating with the pump inlet P2 through a check-valve 224. Excess pressure in the circuit 230 is relieved by a valve 201 delivering into the pump case 11 which is connected through a further relief valve 202 to tank. A valve 208, corresponding to the valve 207, but arranged to be loaded by half the pressure from the servo pump through two restrictors 285, 287 and a check-valve 289 limits the pressure in the exhaust chamber of the servomotor to servo pressure and spills any surplus into the circuit 230. Restrictors 205, 206 provide a pressure drop to operate the valve 203, or a valve 204 when P2 is the delivery port, to operate the servomotor in response to excess flow while a further valve 200 loaded through a plunger 218 by the output pressure from the variable displacement pump provides a relief valve for the servo pump 52, excess flow passing through the valve 201. Fluid spilled through the latter valve flows through passages 244 to cool the port plate of the pump before passing into the case 11. If the inlet port demands more fluid than the circuit 230 can supply, pressurized fluid from the pump case flows back through the passages 244 and the valve 201. The shaft 112 has a handle (111) Fig. 3 (not shown) at one end to operate the follow-up valve 118 and an indicator (140) at its other end.

Title: Forming non-woven fibrous webs
IPC: D21F1/02
Filed: 1975-09-24
Abstract: 1522167 Paper-making BELOIT CORP 24 Sept 1975 [30 Sept 1974] 39147/75 Heading D2A To manufacture paper having a base layer e.g. of unbleached kraft stock, and a relatively thin liner layer, e.g. of bleached kraft stock, a single stratified jet of stock is discharged from a headbox 33 onto a substantially horizontal wire 28 of a fourdrinier machine with the liner layer 36a adjacent the wire and the base layer 36b above the liner layer such that the lower liner layer 36a can be dewatered, e.g. by forming board 30 and table rolls 31, quickly to prevent intermixing of fibres in the two layers 36a, 36b. As shown in Fig. 6 the headbox 40 preferably used is divided into two separate flow channels by partitions 42 and 45 at the inlet and outlet of diffusers 43a-43e and by a compliant partition 49 anchored at its upstream end to a perforated plate 46 together with other flexible trailing elements 50. The partition 49 has relatively flexible portions 49a, 49c spaced by a relatively stiff portion 49b such that the velocities of the separate stock streams discharged from the slice 48 remain equal. Headboxes of this type are described in U.K. Specifications Nos. 1443540 and 1492323.

Title: Improvements relating to data recording
Inventor: NIQUETTE REAMAN PAUL
IPC: G11B20/12
Filed: 1966-09-02
Abstract: 1,144,588. Controlling relative movement of records and transducers. SCIENTIFIC DATA SYSTEMS Inc. 2 Sept., 1966, No. 39343/66. Heading G5R. .  [Also in Division G3] Signals induced in a record head 21 during reading of recorded data by a trailing read head 20 are fed to a circuit which provides control signals indicative of the presence and absence of recorded data to control the relative movement of the record 10 and heads 20, 21. The system is intended to initiate slowdown of a tape while reading is still in progress, eventually to stop the tape with the head assembly centrally in an interrecord gap. A high torque D.C. motor 12 drives the tape 10 via capstan 11 and is controlled by a regulating amplifier 13 operating on an error signal at 14 derived from a D.C. tachometer 15 and a reference voltage normally supplied by a computer-controlled generator 16 which also provides ramp functions for starting and stopping the motor. During recording, binary input signals from flip-flops 22-1 &c. are gated by a write-enable source 24 to respective components 21-1 of the write head 21 via amplifiers 25-1 resistively coupled to a gate 26 to prevent current flowing in the absence of a write command. A readafter-wite check may be conducted by read head 20. During playback, with no write command operative, the signals induced in each write head component 21-1 &c., are monitored via respective limiters 28-1 and amplifiers 29-1 connected through OR gate 30 to an integratoramplifier A, 31. The absence of signals fed to the amplifier A when a GAP reaches write head 21 causes the amplifier to operate switch 18 which connects a lower tape speed reference source 19 into circuit thereby developing a large error signal at 14 to slow the tape, it being finally stopped when the read head 20 senses the GAP. An inverter (33) (Fig. 3, not shown) and a Schmitt trigger (32) may be interposed between the integrator A and switch 18 to ensure positive switching. The system may also be employed during recording and reverse tape movement by monitoring the read head 20. A modified circuit (Fig. 4, not shown) enables current to be passed through the recording head in opposite directions when the NRZ-1 recording technique is employed.

Title: Dc pulse control circuits including a fault detector
IPC: B60L3/00
Filed: 1974-09-10
Abstract: 1476129 Motor control protective systems GENERAL ELECTRIC CO 10 Sept 1974 [17 Sept 1973] 39435/74 Heading H2K [Also in Division H3]  A D.C. pulse control motor drive circuit including a repeatedly operated power averaging switch has a fault detector with sensing means Q1, 40, 51 connected across the switch 16, 17 and arranged to produce a fault signal if the switch 16, 17 remains conductive beyond a predetermined period of time, and with reset means 26 set for a predetermined number of operations. A gating control 18 normally apportions conductive to non-conductive intervals to an SCR16 for controlling the time arranged voltage across a motor having an armature 10 and winding 12. During the non- conductive periods of 16 the voltage at the base of a transistor Q1 makes it conduct and capacitor 51 is charged so that within the time period set by 40 and 51 the output signal to terminal CL of a flip-flop 22 is maintained whilst the transistor Q1 is nonconductive as SCR16 conducts. If SCR16 fails and continues to conduct the capacitor 51 will continue to discharge and the signal to terminal CL of flip-flop 22 will effectively cease so that the output to an inverter is changed from a logic 0 to a logic 1 and a transistor Q2 ceases to conduct. The transistor Q2 is in series with a selected one of a pair of contactors F, F 1 , F 2 , and R, R 1 , R 2  having their contacts in the motor circuit. An electromechanical bypass contactor has its contacts 17 connected across the SCR16 and is arranged so that when it is energized a biasing voltage is applied to a terminal 21 to maintain Q1 in a conducting state. A fault signal (a logic 1) at the output of the flip-flop 22 is also fed to a time log circuit 60, 61 and connected by an inverter 62 to a logic D which is applied to S terminals flip/flops 22, 26 allowing the former to reset if the 0 signal at its input CL has disappeared and setting the output of the latter so that a further signal to the circuit of 60, 61 does not provide a second resetting action. On motor starting closure of a switch a S1 forward-backward selector 59 for contactor coils 57, 58 is in a neutral position so that neither contacts F1, F 2  or R 1  R 2  are closed but voltage is applied via resistor 42 to the SCR16 and, provided this is not short circuited, the voltage at the base of transistor Q will allow conduction to change capacitor until a signal at CL of flip-flop 22 results in conduction by transistor Q 2  whereby operation of switch 59 can energise either the forward or reversing contactor (F, F 1 , F 2  or R, R 1 , R 2 ).

Abstract: 1,260,034. Carbonizing. COAL INDUSTRY (PATENTS) Ltd. 17 July, 1970 [12 Aug., 1969], No. 40276/69. Heading C5E. [Also in Division C1] A porous carbon body is made by sintering a particulate pitch-like material, at a temperature below its melting point, to produce a green compact, oxidizing the green compact to stabilize it to heat treatment and carbonizing the stabilized compact. Pitch-like materials referred to are: coal extracts, solutions of coal, coal-tar pitches, petroleum pitches, asphalt, bitumen and industrial by-products, and may be mixed with finely divided carbon. In the example, particles of an extract, made by extracting a low-rank coal with anthracene oil at 400‹ C., are placed in a cylindrical mould, and a plunger placed on top. The particles are sintered at 205‹ C. while pressure is applied to the plunger. The green compact is removed from the mould, cooled, placed on a flat porous metal sheet and heated in air at 200‹ C. to oxidize it. It is then heated in static air to 300‹ C., then to 600‹ C., and finally to 1000‹ C. in nitrogen, and cooled in an atmosphere of nitrogen. The porous bodies may be activated by heating in steam.
