The description is substantially identical with that of the parent Specification but the claims relate to the arrangement for gating those pulses of a train either until, or after, the setting of a flip-flop, to an accumulator stage, the relative time at which the flip-flop is set being determined by the decimal key depressed in the order corresponding to the accumulator stage. This effects the addition or subtraction of the key set number into the accumulator.

Title: Industrial process control apparatus
IPC: G05B7/02
Filed: 1962-09-12
Abstract: 987,897. Automatic controL FOXBORO CO. Sept. 12,1962 [Sept. 14,1961], No. 34862/62. Heading G3R. To avoid shock when switching from manual to automatic control of a variable, e.g. temperature or rate of fluid flow, the automatic system is arranged to supply a dummy load with a signal equal to that of the control signal when this is provided manually, and it is ensured that the balanced condition of the system is maintained immediately following change over. The automatic system comprises a transistor amplifier 34 whose input is normally an error voltage 24, derived from a transducer 10 and reference source 22, 20, backed off by negative feed-back from a reset circuit 68, 70 having a long time constant. With switch 26 in the manual position, however, (opposite to that shown) the amplifier input terminals 30, 32 are connected to two equal resistors 78, 80 carrying current to dummy and real loads respectively so that any difference between these currents is eliminated by an appropriate signal to the amplifier and consequent adjustment of the current in the dummy load 76, which therefore "tracks" that through the real load 58 (e.g. a control valve) supplied by manual adjustment of a rheostat 72 from a source 52. At the same time the error signal 24 is connected directly to one side of the reset capacitor 68 in the feed-back circuit, the signal to the other side now corresponding to the manual signal, which the amplifier is tracking. Hence, upon switching to automatic control, the feed-back voltage is equal and opposite to the error signal at that instant and so the input voltage to the amplifier is zero and the system remains balanced, supplying the real load with the current previously flowing through the dummy 76. Automatic control is gradually re-established at the rate permitted by the time constant of the reset capacitor circuit. The amount of correction applied in response to a given change detected by the transducer 10 is adjusted by a potentiometer 64 in the feed-back circuit, and it is stated that a meter may be provided so that the manual signal may be adjusted to the prevailing automatic one before switching to manual control.

Abstract: A composition comprises natural or synthetic rubber and a thermosetting reinforcing component which consists essentially of a resin comprising or incorporating a spaced polyphenol and a formaldehyde-based cross-linking agent therefor.  The term spaced polyphenol means a substantially unbranched aliphatic hydrocarbon containing substituent phenolic nuclei in which the carbon atoms to which the nuclei are attached are separated along the hydrocarbon chain by, on the average, more than one carbon atom, and the chain-chlorinated derivatives thereof.  The resin may be mixed with or may be formed by reaction in a conventional novolac resin.

Title: Improvements in liquid friction brakes
IPC: F16D57/06
Filed: 1953-12-16
Abstract: 740,439. Fluid friction brakes. GASSOT, R. J. L. Dec. 16, 1953 [Dec. 17, 1952], No. 35003/53. Class 103 (1). A fluid friction brake of the kind described in Specification 646,173 has vanes 1 of arcuate form which may be projected out of a correspondingly shaped recess 4 in the hub member 3 into the annular space 5 so as to provide a braking obstruction to liquid impelled by the lug 7 rotating with the drum 6. The vane 1 is projected by means of a piston 12 under the action of pressure in a conduit 30, the liquid forces on the vanes being balanced by passages 8, 9, 10 and 11 therethrough. The vane 1 is pushed back into its housing as the lug 7 approaches by pressure on the face 15 and in order that no variation of pressure shall occur in the conduit 30, compensation pistons 17, Fig. 3, are simultaneously moved back by the action of a roller 41 engaged by a cam 13 on the rotating drum. Fig. 7 shows how liquid may be drawn off by centrifugal action, passed through a radiator 22 and returned to the low-pressure side of the liquid space. The brake is normally applied by supplying pressure to the conduit 30 to eject the vanes 1, of which there will usually be one more than the number of lugs 7. Fig. 8 shows a mechanical locking arrangement which only becomes operative when the brake rotor speed is substantially zero, so as to immobilize a vehicle for long periods such as when on hills. When the brake is operating normally pressure from . the space 5 acting through passage 28 moves piston 27 to the left so to cause cam 13 to bear against piston 17 and keep teeth 53 on the cam out of engagement with teeth 27 integral with a fixed part of the brake. If the brake speed should fall to substantially zero, pressure from the control conduit 30 overcomes that in space 5 so that the pistons 17 and 27 are moved to the right locking teeth 53 with teeth 29 to prevent rotation. Joint rings 36 and 36<SP>1</SP> simultaneously engage to preserve fluid tightness. Where remote control by use of a cable is required, however, the cable 33, Fig. 9, may be progressively released to allow a spring 34 to operate a master piston 43 located in a recess in the housing.

The resinous binder may be a phenolic, polyester or especially an epoxy resin which is a diglycidyl ether of bisphenol A having an epoxide equivalent of 175-16000. This may be cured with a polyamine or a polyamine/epoxy resin adduct. The composition may also contain up to 70% by wt. of a solvent for the resin, which may be a high molecular weight diglycidyl ether of bisphenol A having epoxide equivalent of 5000-16000; this does not necessarily require a curing agent. Examples' relate to the use of binders comprising the above epoxy resins, a phenolic resin and a polyester prepared by reacting maleic acid with diethylene glycol and catalysed with methyl ethyl ketone peroxide.

Abstract: Extrusion tubes (1), Fig.1 (not shown), of a honeycomb-forming die may be made by electro-depositing layers of metal, e.g. hard chrome, nickel or copper and a final layer of hard chrome, on a destructible core.  The core may be of aluminium removed by reaction with an alkali. Extensions (10) may be formed integrally with tubes (1) if of the same cross-sectional shape.ALSO:A honeycomb element of ceramics, glass or metal intended for use, e.g. as a light-weight building component or catalyst support, is made by extruding material through metal tubes 1, rigidly clamped together by means of a frame 6, into extensions 10 sealed by closures 11.  The <FORM:1099519/C1/1> material is forced by the extrusion pressure to move through a plurality of orifices 12 in each extension 10, the strands thereby formed moving parallel to the extensions and coalescing to form the walls of the honeycomb, the cavities thereof being defined by extensions 10 which act as mould cores.  The cross-sectional shape of the extensions 10 may vary, Figs. 2-4 (not shown), and the maximum cross-sectional dimension may be small, e.g. 0.5-5 mm.

The suture 12 if absorbable, e.g. catgut, is immersed in a conditioning liquid 14 in the envelope 11 and which may be ethyl alcohol or a mixture of ethyl and isopropyl alcohols and water and may contain either a bactericidal or a rust inhibiting agent. Sutures of silk, synthetic fibres and steel are dry packed. Each envelope may be formed of two sheets of cellulosic material or a laminate having an external polyester film with an internal polythene or polyvinyl film. The two sheets are adhered or heat sealed together to form a pack 15 with a tip 16 and they extend beyond this to form lips. Preferably the sheets are oversealed i.e. time, temperature and pressure are adjusted so that the inner film is displaced from between the outer films along the seal lines to facilitate tearing the seal. To form the package the seal 15 and the side seals 18 of the envelope 11 are formed, the suture 12 inserted in the envelope 11 which is then sterilized by heat, ethylene dioxide gas or radiation, the liquid 14 is introduced (if necessary) and the bottom seal 19 is formed. The process of sealing and sterilizing is repeated for the envelopes 20, 22. Alternatively each envelope may be formed from a single sheet bent double and the seal 15 is formed last. A cutting line 21 is formed on the envelope 20 so that envelopes 20, 11 may be opened in one operation.
