Title: Improvements relating to the manufacture of carpets and similar fabrics having a tufted surface
Inventor: BRINTON ESME TATTON CECIL
IPC: D04H11/00
Filed: 1950-08-31
Abstract: 703,075. Pile fabric looms. BRINTONS, Ltd. Aug. 20, 1951 [Aug. 31, 1950], No. 21541/50. Classes 142(2) and 142(4) Pile yarn wound on spools carried by chains is attached by adhesive to a backing without removing the spools .from the chains. the operation being speeded up by giving an angular movement to the spool with respect to the chain while the chain is being displaced so that the spool presents the yarn to the backing for a longer period. Pile yarn spools 125, mounted on chains, have rollers 106 at each end engaging grooves 150 in a pair of plates 152 and are also provided with a pair of arms 108 carrying rollers 112 engaging grooves 151 in a second pair of plates 153. The grooves are so arranged that a spool moves to lay the pile yarn between electrodes 41, 160 and so that the spool moves from a position 125c. to 125d to draw off sufficient yarn for another row of tufts and to cause a dwell while the yarn is cut by a cutter 162, 163. The cutting device is of the kind described in Specification 624,882. A backing of hessian from a beam passes over a tensioning device connected to a brake band around the beam so that the brake is applied if the backing is let off too quickly and vice versa. The hessian 1 passes over a roller dipping into a trough containing adhesive. A spring-loaded roller presses the hessian towards the roller arid a spring-loaded spreader blade for the adhesive is provided. The hessian then passes over the fixed electrode 41 where dielectric heating causes the adhesive to secure the tufts 46, as described in Specification 656 525. The . spools are braked by a flat plate which is pressed by a spring against the turns of yarn. The "tubes" through which the yarn is led from the spool comprise a number, of ducts of channel form soldered to a base and fitted with a cover plate retained by a spring. Spring ball catches retain the "tubes" in the angular position at which they leave the plates 152, 153. The newlyformed tufts are of open V-form and a wire, moved by cams, passes behind the last formed row of tufts and draws the two arms of each tuft together. A take-up mechanism is operated by ratchets.. An electric motor, driving the machine through a variable speed gear box, provides reciprocating motion for the electrodes and shears, drives the spool chains and take-up mechanism, and moves the wire that draws together the arms of the tufts. A hand-operated clutch is provided in the drive for the spool chains; a second clutch is provided in the drive to the electrodes and shears. Specification 624,883 also is referred to.

Patent GB-1188997-A (GB)
Title: Multi-Phase Traffic Actuated Control System
IPC: G08G1/08
Filed: 1967-05-11
Abstract: 1,188,997. Road traffic signals. LABORATORY FOR ELECTRONICS Inc. 11 May, 1967 [14 Oct., 1966], No. 21974/67. Heading G4Q. A traffic signal controller comprises a twostage ternary counter 41, Fig. 3, which produces an output on one of the lines 51-59 which are connected to a plurality of phase circuits (15, 17, 19, Fig. 2, not shown), one for each traffic phase, to indicate the steps in each phase, and the phase circuits in turn feed back to the counter to advance it as required. When the counter is in stage 6, an output on line 56 is fed to a logic circuit (Fig. 4, not shown) which determines which phase shall next receive rightof-way. The system illustrated comprises three phases, and the logic circuit arranges that rightof-way passes to the next phase in sequence in which a demand has been registered; the circuit also ensures that right-of-way can be accorded to only one phase. When the phase sequence has been selected, the counter advances through positions 7 (amber) and 8 (all red) and the transfer position 9 to position 1 which grants rightof-way to the new phase. If there are pedestrian demands the next advance pulses on line 62 step the counter through positions 2 and 3 which include pedestrian right-of-way and pedestrian clearance signals respectively; if there is no pedestrian demand the advance pulse passes through gate 119 to set the counter to position 4, thereby skipping the pedestrian periods. In position 4 an initial green period is provided of a duration dependent on the number of vehicles which have been waiting. Each time a vehicle crosses a detector and is halted at the signals, a capacitor (594, Fig. 6, not shown) is discharged by an increment, thereby increasing the initial green time when rightof-way is transferred to that route. If the system is entirely vehicle controlled the counter rests in position 5 until there is a demand for right of way on another phase. Such a demand starts a maximum green timer (Fig. 5, not shown) and also a gap timer which prevents transfer of right-of-way if the gap between vehicles is sufficiently short. This comprises a resistance-capacitor timer (406, 407, Fig. 5A, not shown) which is reset each time a vehicle is detected, and a further resistance-capacitance timer (402, 403), the voltage across the capacitor being added and fed to a trigger device so that the permissible gap decreases with time. If the green period is ended by the maximum green timer before a demand is satisfied, the call is remembered and ensures return of rightof-way at the earliest opportunity.
Patent GB-495900-A (GB)
Title: Improvements in the manufacture and production of allyl chloride
IPC: C07C17/00
Filed: 1937-08-11
Abstract: Allyl chloride is produced by reacting excess of propane or propyl chloride or mixtures thereof with chlorine at 500-700 DEG  C. in the presence of a metal catalyst which is stable to hydrogen chloride. Suitable catalysts are chromium - nickel and chromium - nickel - iron alloys, platinum, rhodium, silver, tungsten, tantalum, niobium, osmium, and alloys containing these metals. They may be used in the form of netting, rolled-up netting, spirals, threads, granules, balls, or cuttings.  Shaped carrier materials may be used carrying a coating of these metals having good heat conductivity, and a thin coating of lustrous carbon may be produced on the surface of the metal, for instance by burning-in a thin layer of brown coal tar. The reagents may be introduced separately into the apparatus, being mixed a short distance in front of the catalyst, and one or both may be preheated.  The preheating should be such that the mixture is at at least 150 DEG  C., and the mixture is passed rapidly over the catalyst which is initially at at least 350 DEG  C., but may be at the reaction temperature.  The heating of the catalyst is discontinued when the reaction starts, and cooling may be applied if necessary. In examples, the reaction of chlorine with propane, propane mixed with propylene, and propyl chloride mixed with propylene respectively is described.  The chlorine is led in through a narrow perforated tube within an outer tube which receives the other reagent (preheated), the catalyst being rolled-up chromium-nickel wire netting.

Title: Inertia operated control device
IPC: B60T8/74
Filed: 1949-08-26
Abstract: 662,029. Fluid pressure brakes. WESTING- HOUSE AIR BRAKE CO. Aug. 26, 1949 [Sept. 28, 1948], No. 22289/49. Class 103 (i). The invention is concerned with the prevention of wheel skid due to excessive brake application, particularly in aircraft. The internal drum brakes on an aircraft wheel hub, Fig. 1, are applied by fluid entering the annular resilient tube actuators 7, 15 of known type, the fluid being controlled by a valve 17, Fig. 5, having a supply port 62, a connection 67 to the brake actuator tubes, a main atmospheric exhaust port 58 controlled by valve element 56 and an auxiliary atmospheric exhaust port 82 controlled by valve element 71. A casing 23, rotatable with the wheel, contains an inertia wheel 33 which is geared to the casing by hypocycloidal gear-wheels 39. When the speed of rotation of the aircraft wheel is steady, the casing 23 and the inertia wheel 33 rotate together, but should the effect of braking retard the wheel more than a predetermined rate, say ten miles per hour per second, the inertia of the wheel 33 causes rotation of the frame 38 carrying the gears 39. This causes actuation through lever 28 coupled to lever 29, Fig. 5, of valve 71 to release air to atmosphere from chamber 64 of valve device 17. This results in an unbalance of the forces acting on the valve member 51 which is moved down to release air from the actuator tubes 7, 15 through the main exhaust port 58, thus reducing the braking effect and avoiding the wheel skid.
