Title: Improvements in or relating to flexible couplings
IPC: F16D25/04
Filed: 1939-03-13
Abstract: 520,671. Universal joints. GENERAL TIRE & RUBBER CO. March 13, 1939, No. 8028. Convention date, March 26, 1938. [Class 80 (ii)] Concentric inner and outer shaft-heads 14, 17 are drivingly connected by a flexible pneumatic annulus 15, and end-thrust, for example due to a marine propeller shaft, is yieldingly resisted by a rubber ring 19, arranged nearer to the joint axis than the pneumatic annulus so as not to be subjected to excessive deformation when the shafts are misaligned. In Fig. 1. an endless or segmental rubber thrust ring 19 is clamped between double conical elements 20, 22 secured to the respective shafts, the outer element 22 being split and drawn together by bolts 23 to subject the ring to initial compression. The pneumatic annulus 15 is reinforced by radially disposed cords 15a. In Fig. 3, the pneumatic annulus 25 is vulcanised to concentric metal stampings 26, 29, bolted at 31, 35 to the respective shafts, the annulus having an inner integral thrustsustaining portion 37, vulcanised respectively to a flange 28 of the inner member 26 and to a member 36, bearing against a plate 34 attached to the outer member 29 by bolts 32 which subject the thrust-sustaining portion 37 to initial compression.

Abstract: 527,017. Covering aircraft structures &c. BLACKBURN AIRCRAFT, Ltd., and STIEGER, H. J. March 13,1939, No. 8080. [Class 4] Fabric or thin sheet metal is attached to a support such as the channelled rib of an aeroplane wing by means of a pin having a pointed end 4, Figs. 3 and 4, a cranked part 3 and an eyelet 2. The part 4 is passed through registering holes in the fabric 5 and the channel 7 of the rib 6, and, in some cases, in a reinforcing strip 8. The pin is then turned till the part 4 engages beneath the channel, and the part 1 lies on the reinforcement. A second pin is then passed through the eyelet 2, and a further portion of the fabric is secured. The eyelet of the last pin to be inserted is secured by a screw or other device, for example the hooked device 2a, 1a, 3b shown in Fig. 7. The part 1 may be straight as shown, or it may be curved and thicker at its central part than at its ends. The pin may be made of wire or sheet metal and be of a cross-section conforming to the contour of the support for the fabric. In some cases, the eyelets are adapted to be sprung open.

Title: Logic control circuit
IPC: H04Q9/14
Filed: 1973-02-20
Abstract: 1414221 Selective signalling COAL INDUSTRY (PATENTS) Ltd 8 Feb 1974 [20 Feb 1973] 8229/73 Heading G4H A control unit stores received information and on recognizing its address in the information, monitors another part of the information. In a coal mine, advance of roof supports and lateral advance of a conveyer used by a winning machine are controlled over a common conductor from a central unit by means of a local unit associated with each support. Each local unit has a 16-stage shift register to receive a control message consisting of a "1" bit followed by 3 control bits followed by 8 address bits, shifting of the message into the register being started by arrival of the "1" bit at its input to start a clock generator. When the message has just been entered, the "1" bit (now in the 12th stage) stops the shifting and enables a comparator to compare the address bits with a stored reference address entered on switches. Equality gates out the 3 control bits to perform the control functions and causes the "1" bit in the 12th stage to be shifted along to the 16th stage thereby selecting in turn 4 analogue measurements (e.g. roof support pressure) which are then sent over the common conductor to the central unit. Some local units may have the same address. The message from the central unit may be sent more than once, the different received versions being compared, action being taken only if equal.

Title: Process and apparatus for washing and/or concentrating pulp
IPC: D21C9/02
Filed: 1943-05-31
Abstract: In a method of washing or concentrating pulp it is projected in a thin layer over an inclined permeable surface over which it sweeps into a washing tower or other washing means.  Pulp to be treated is fed from a <PICT:0565956/IV/1> rectangular nozzle 11 over a sloping screen surface of wire gauze 9 to a tower 1, liquor which passes through the screen 9 into the box 12 being drawn off through a pipe 13.  Pulp is withdrawn at a pipe 2 at the bottom of the tower 1 and circulated by pump 15 through a pipe 3 into a pipe 4 from which it is discharged through a downwardly directed centrifugal spray nozzle in a conical sheet at a small angle over a conical screen surface 10 over which it sweeps back into tower 1.  Water may be supplied as necessary to tower 1 through one or both valves 27, 28 to keep volume of pulp substantially constant until the pH value is at desired point for bleaching.  The desired quantity of bleaching liquid may be admitted to tower 1 through valve 30 from tank 29 and pulp circulated by pump 15 until bleaching is complete.  Acid may be added to pulp and washing resumed, and after final washing pulp is discharged to one or other of storage tanks 6, 7 from which it may be delivered to a beater 8 or other apparatus.  Washing water may be heated by introducing steam at pipe 35.  Specification 199,001, [Class 69 (iii)], is referred to.

Electric switching means are described to prevent actuation of the fan whilst the valves rare intermediate the operative positions. Thermostats are mounted in rooms A, B to control the fan and control means respectively.
