Title: Rubber latex adhesive compositions
Inventor: MOSS CHARLES
IPC: C09J107/02
Filed: 1956-06-30
Abstract: A quick setting latex adhesive is prepared by digesting rubber latex with a proteolytic enzyme, preferably for a time sufficient to decompose a major portion of the protein content of the latex, e.g. from one to two days at 15 DEG  to 20 DEG C., and after the digestion a re-stabilizer, e.g. a cellulose ether, is added to the latex. The enzyme may be trypsin, erepsin, pepsin, or papain, and 0,01 to 0,1 parts by weight thereof may be added to the latex per 100 parts of rubber.  The latex to which the enzyme is added may contain ammonia as a preservative, or ammonia and a sodium salt of polychlorophenol. After the latex has been re-stabilized it may, if desired, be de-ammoniated.  The resulting adhesive may be modified by the addition of an emulsified solvent, resins, or emulsified polyisobutylene, and is then particularly useful for bonding yarn ends in yarn splicing during carpet manufacture.

Title: Improvements in or relating to systems for controlling the air pressure in aircraft cabins
Inventor: SWAFFIELD PHILIP JOHN
IPC: B64D13/04
Filed: 1950-08-18
Abstract: 711,270. Automatic control systems. NORMALAIR, Ltd. Aug. 17, 1951 (Aug. 18, 1950], No. 20498/50. Class 38(4) In a system for automatically controlling air pressure in an aircraft cabin a switch operates when cabin pressure falls below a predetermined minimum, to effect maximum delivery from an air pressure supply source to the cabin. Air is delivered from a blower (not shown), through a conduit b to a pressurized aircraft cabin a. The metering head (not shown) of a mass flow controller as described in Specification 655,328 is located in conduit b and operates a diaphragm 12<SP>1</SP> to control, through contacts 12 and relays 15, 16, reversible electric servomotors 17 operating spill valves (not shown), as described in Specification 668,564, [Group XXIX], which spill air to maintain a constant mass flow in conduit b. Servomotors 17 may be controlled manually by a switch 14 instead of automatically if switch 13 is moved from the position shown. A switch 2 responsive to cabin-temperature normally controls through relays B and C a reversible servometer d having a permanent field and operating a throttle valve c in conduit b to control temperature. Excessive temperature or pressure in conduit b causes operation of switches g and f respectively to energize a relay A thereby causing operation of valve c to a fully open position. Valve c is also operated to a fully open position by the energization of a relay E when the spill valves are fully closed. Should cabin pressure fall to a predetermined value a pressure operated switch 7 is operated by means not shown to energize a relay F so that (a) a relay D is energized to cause operation of valve c to a fully open position, (b) the mass flow controller is rendered inoperative, (c) the spill valves are closed. A lamp 8 gives warning of this condition. An arrangement in which cabin air bled from the centrifugal blower of a jet propulsion unit is controlled by a flow control valve instead of a spill valve is referred to. The air supply to the cabin may pass through a cooler supplied with " ram " air for cooling.

Title: Improvements relating to rectifying arrangements employing discharge devices
IPC: H02H7/127
Filed: 1937-07-28
Abstract: 500,191. Converting ; control systems for consumption apparatus. LA VERRERIE SCIENTIFIQUE., and LENZ, P. July 28, 1937, Nos. 20889 and 20890. Convention dates, July 28, and July 22. [Classes 38 (ii) and 38 (iv)] Switching control.-A rectifying arrangement comprises a discharge device 1 having one or more auxiliary anodes 15, Fig. 1, connected through charged condensers 18 to the main anodes to enable the discharge to be rapidly extinguished. In normal operation the auxiliary anodes are blocked by grid control. As shown a welding transformer 6 is supplied and extinction of the discharge is effected in dependence on the load current bv means of a relay 27 energized from a resistance 30 in the load circuit. This relay short circuits the transformer 12 supplying grid potentials to the main anodes 3 to allow these to be blocked by a source of bias 13, and energizes a relay 37 which operates after a time delay to remove a short circuit from a transformer 26 supplying grid potentials to the anodes 15 which become conductive to extinguish the main discharge. A maintaining circuit 33, 34 for the relay 27 is provided and may be arranged to reset the relay after a time delay ready for a fresh actuation. In a modification one auxiliary anode is used and the control potential for this is applied through an auxiliary discharge device brought into operation by the relay 27 and controlled in dependence on the current in a main anode circuit. In a further modification, Fig. 3, both relays are replaced by auxiliary valves. Operation is initiated by the actuation of a relay 68 under the control of a pedal or similar device. Extinction of the main discharge is initiated by a valve 56, controlled in dependence on load current and voltage, which applied a negative bias to the grids controlling the main anodes, and through a transformer 72 applies a time delayed control potential to the valve 45 which initiates discharge from the auxiliary anode 15 to extinguish the main discharge. The valve 45 is extinguished by a relay 76 which temporarily short circuits the valve.

Title: Improvements in and relating to time-recording apparatus for the flight of carrier pigeons
IPC: G07C1/26
Filed: 1920-07-12
Abstract: 149,258. Krum, G. June 19, 1916, [Convention date]. Portable checking and recording clocks for carrier pigeon races &c.-(a) The insertion of a token provides for the release of the token receptacle, which can then be manually rotated into position for the insertion of the next token; (b) a pencil is arranged to be drawn across and cancel the paper strip when the cover fastenings and seals are tampered with; and (c), the clock is stopped by hard shaking designed to accelerate the rate of the clockwork movement, a spring member being forced into engagement with the compensating balance wheel. According to (a) the insertion of a token 1, Fig. 3, through the slot 2 in the cover 3 into a division of the token receptacle 4 forces a projection 5 into engagement with an arm 6 of a disk 7. The sleeve of the disk 7 has a groove 20 with which engages one end of a bell-crank lever 8, and by the depression of the disk along the squared upper end of the shaft 15 and against the action of a spring 16 the other end of the lever 8 is moved out of the path of a cam 11 on the cross shaft 10. By now rotating the shaft 10 by means of a handle, the shaft 15 is rotated through worm-and-wheel gearing 13, 14. On the upper end of this shaft is a pinion 18 in gear with a toothed rim 19 of the member 4. When the operating handle has made one revolution, the token receptacle has been moved into a position in which the next division is under the opening 2 in the cover, ready for the insertion of another token. In this position, the shaft 10 has moved so that the cam 11 allows the lever 8 to move back under the action of a spring and the disk 7 is lifted, an arm 6 snapping into a recess in the member 4, locking it in this position until released by the insertion of a fresh token. (b) The clock is placed inside a cover for protection, with lead seals and locking bolts. One bolt 23, Fig. 6, has a shoulder 24 which presses against a crank lever 26 rotatable about a pivot 25 and connected to a sliding bar 27 carrying at its lower end a pivotally - mounted pencil holder 29. When the cover is closed, the shoulder engages the lever 26 moving the bar 27 down until the free end of the member 29 is held on one side by a stop. Tampering with the cover withdraws the bolts, releases the lever 26, and allows the slide bar 27 to be pressed up by a spring. This releases the member 29 from the stop and permits a spring 34 to move its lower end across the paper, the pencil 35 leaving a stroke to cancel the strip. (c) If the clock is shaken to quicken rate of movement, a pin 38 on an arm 40 of the spindle 39 provided with weighted arms is rotated into engagement with one end of a spring lever 41, the other end of the lever being thereby moved into the path of thecompensating balance wheel 42 to stop the clock, as shown in Fig. 11.
