Title: Road surface marking tape material
IPC: G02B5/12
Filed: 1974-01-17
Abstract: 1463681 Road surface markings L EIGENMANN 17 Jan 1974 [22 Jan 1973] 2182/74 Heading E1G [Also in Divisions B1 and B2] A tape material for laying on and adhesively securing to the upper face of a preliminary formed and doctored primer layer on a roadway to form a traffic regulating sign comprises a flexible upper layer superimposed on and intimately connected to a flexible lower layer, the upper layer being at least greater than half the thickness of the material than the largest dimension of particles embedded in the upper layer, the upper layer consisting of a composition including a polymeric binder having a multiplicity of particles embedded at various levels within it some of the particles consisting of a substance of hardness not less than 6 Mohs' Hardness Scale and arranged to provide a multiplicity of hard and sharp points protruding from the planar upper surface of the layer to impart anti-slip properties thereto, and to maintain said properties by emerging the more deeply embedded particles as the layer is worn down by traffic, the lower layer consisting of a second composition forming an adhesive bond with the composition of said upper layer. The particles may be of orthoclaze, quartz, aluminium silicofluoride or silicon carbide. In an exemplified tape Fig. 1 a road pavement 10 is primed with a bitumen layer 12 to which the tape is applied. The tape comprises a lower layer 14 and an upper layer 18. The lower layer is flexible or pliable so as to permit the entire tape to be wound up into a coil for storage. Preferably the upper and lower layers may be of transparent material and the lower layer may also comprise pigments such as whiteners and opacifiers. While the layer 14 may be as thin as possible within the limits of utility the upper layer is necessarily thicker. The hard particles 20 protrude from the upper layer and consist of crystalline particles of a hard substance such as corundum or silicon carbide which may be coated with a resinous layer and a layer of glass beads. The intermediate binder layer may be of the same composition as the upper layer 18, but including light reflecting on light diffusing fillers such as aluminium flakes or titanium dioxide. In a further embodiment smaller individual sharp particles are mixed with larger glass beads and bound in a resinous binder to form the layer 18. The layer of powdered mixed particles may be applied by extrusion onto the lower layer followed by blowing the surface of the uncured binder to reveal the particle tips. In a further embodiment the extruded layer is calendered to form protrusions and the protrusions are then roller coated with a binder. The particles and reflective beads are then dropped to form a layer on the binder. The upper and lower layers may be co-extruded. The lower layer may be of acrylonitrile rubber, styrene or styrene/butadiene rubber, acrylic polymers, or epoxy resins. The lower layer may be reinforced by fabric or canvas. The transparent binder may be a polyurethane resin.

Title: Improvements in or relating to irreversible mechanisms
IPC: F16D41/00
Filed: 1941-02-22
Abstract: 546,134. Gas meters. ROBINSON & CO. (LIVERPOOL), Ltd., J. H., ROBINSON, D. M., and ORMEROD, G. A. Feb. 22, 1941, No. 2439. [Class 54] [Also in Group XXIV] Consists in means for preventing reverse rotation of a part, and stated to be applicable as a one-way clutch. As applied to a gas meter, an arm 1 is rotated by the usual bellows about the axis of a shaft 2 on which it is mounted, this shaft having crank connections with arms 3, 4 attached to gas controlling valves 5, 6. A plate 9 on the fixed casing 13 of the meter frictionally supports a disc 10 having a projection 11 adapted under certain conditions to engage a fixed stop 12 on plate 9. The disc has a slot 16 to accommodate the shaft 2, and an upstanding finger 14 to engage a slot in the arm 1. For counter-clockwise rotation of the arm, Fig. 3, frictional drag of the disc causes it so to move relatively to the shaft 2 and plate 9 that the projection 11 is kept clear of the stop 12. If, however, the arm 1 tends to rotate in the reverse direction, the drag causes the disc to move across the shaft 2 and plate 9 in the other direction so that the projection 11 engages the stop 12 and rotation is prevented. More than one stop 12 may be provided. An arcuate slot may be formed in the arm 1 to engage the finger 14 and to have the same effect as the slot 16 and shaft 2.

Title: Improvements in or relating to oil-immersed electric circuit-breakers
IPC: H01H33/98
Filed: 1933-01-26
Abstract: 413,751. Oil break switches. REYROLLE & CO., Ltd., A., Hebburn-on- Tyne, and CHRISTIE, J., 4, Sidecliff Road, Sunderland. Jan. 26, 1933, No. 2492. [Class 38 (v).] Arc-rupturing devices ; contacts.-An oil switch has main fixed contacts co-operating with a movable main bridging contact, and fixed arcing contacts co-operating with movable ones adjacent the ends of an oil-filled chamber carried by the bridge-contact, so that pressure generated by the arc at one set of arcing contacts is utilized to drive the oil in the chamber against the arc formed at the other set. In Figs. 1 and 3, fixed main contacts A, B co-operate with the shaped upper surface of a tubular, metal bridge F, which forms the pressure-chamber and is apertured at each end to admit the fixed arcing contacts D, E cooperating with contacts D<1>, E<1> in extensions of the bridge F. The tube F is closed at F<2> and the contact D is shorter than E so that the first arc is formed between D, D<1> and produces the oil-blast for the arc formed subsequently at E, E<1>.The exhaust takes place through a passage shaped to form a flared nozzle by means of baffle plates G which taper outwardly (Fig. 3) and are interleaved with thinner baffles G<1>, which may either extend across the full width of the tube or have slots of different width from that of the plates G. Alternatively, a deflecting block may be inserted in the lower part of the tube-opening, Fig. 4 (not shown), or the tube may be closed at both ends and the contact E provided with a hollow bore with an aperture that is uncovered at a certain stage in the opening movement, Fig. 5 (not shown). Contacts D, E could be made of the same length and E<1> have an extension E<5> (Fig. 3) to ensure the prior breaking. The arrangement is stated to be adapted to existing breakers and to be free from repulsive forces during closure. In Figs. 6 and 8, the fixed arcing contacts are duplicated at each end, as at P, P<1>, Q<1>, and co-operate with contacts M<2> to provide two parallel-connected paths, each in its own chamber, as K<1>. By arranging for the blasts from the chambers to exhaust in opposite directions, reactions due to the blasts are compensated. The chambers as K<1> are formed by means of insulating side plates J, J and a partition J<2>, insulating plates J<3>, J', a central metal bridge L, and mutually-insulated metal plates M, one for each chamber. The parts of the structure are secured by bolts J<5>, with insulating sleeves J<5> to insulate the plates M, and the chamber ends are constituted by insulating closure plates K<2> and baffles K<3> at the exhaust end, Fig. 8.

Title: Improvements in fluidized bed reactors
Inventor: KNIGHT CYRIL HEWSON
IPC: B01J8/18
Filed: 1957-01-24
Abstract: <PICT:0859367/III/1> In a multi-chamber fluidised bed reactor, concentric steel walls 11 and 13 lined with refractory 14 define an inner hollow shaft and an annular treatment space divided into zones A, B, C and D by refractory bed support plates 19, 23, 26 and 29 inset into the refractory lining.  A windbox 17 has valve-controlled conduits 42 supplying fluidising gas, and fuel injectors 50 extend through both inner and outer walls into the second bed 27. Valve-controlled inlet conduit 32 and outlet conduit 40 and overflow conduits 34, 36 and 38 are disposed at angular spacings of about 180 degrees from one another at any single level. Effluent gases pass through a cyclone separator 45 to an offtake 46, separated solids passing by conduit 47 either to waste or through valve-controlled pipes 48 and 49 back to the fluidised beds.  In a modification, Fig. 2 (not shown), the overflow conduit 38 and outlet conduit 40 are placed near one another, but are separated by a vertical partition, thus ensuring a long path for the solids introduced through conduit 38.  A similar arrangement may be applied to the other compartments.

Title: Improvements in Automatic Starting and Stopping Devices for Electrically Driven Air Compressors.
IPC: F04B49/06
Filed: 1918-02-13
Abstract: 124,017. British Thomson - Houston Co., and Sugden, J. Feb. 13, 1918. Controlling compression; stopping pumps automatically.-In apparatus for controlling electrically driven air compressors, electrically operated means are provided for automatically unloading the compressor before stopping the motor which drives it. In the case of an air compressor G delivering through a pipe H to a receiver I, an unloading valve J is provided to open the pipe H to atmosphere and is connected by a pipe F to the upper chamber of a double-acting valve B, of which the lower chamber is connected by a pipe E to the receiver I. When the compressor is inoperative, the valve B connects the receiver to the valve J to allow the compressor to be started without load, and the compressed air also passes from the pipe F through an adjustable restricted opening into a cylinder C and holds up a piston P, against the action of a spring, to open contacts D. When a control switch K is closed, current passes to a coil L<3>, which acts to close contacts L<1>, L<2>, and then passes through the contacts L<2> to an electro-magnet M, which operates the starting- gear for the compressor. The final movement of the starting-gear when the normal speed is approached closes contacts N so that current passes to an electro-magnet A which reverses the position of the valve B to cut off the receiver from the valve J and open the pipe F to atmosphere. The valve J closes, putting the load on the compressor, and the piston P falls, closing the contacts D. When the switch K is opened, either by hand or automatically by predetermined receiver pressure, the coil L<3> is de-energized to open the contacts L<1>, L<2> and de-energize the electro-magnet A, so that the valve B connects the receiver to the valve J to unload the compressor. The compressor remains in action since current is still supplied to the electro-magnet M through the contacts D, but the compressed air from the pipe F is gradually admitted to the cylinder' C to raise the piston P and open the contacts D, whereupon the electromagnet M is de-energized and the motor is thus stopped a predetermined time after the compressor is unloaded. When the invention is applied to compressors of large capacity, especially of the multi-stage type, the loss of compressed air from the cylinders, intercoolers, and piping through the unloading valve J is avoided by the use of a second unloading valve at the inlet of the compressor and a second electro-magnetic valve B and cylinder C, the arrangement being such that, when the compressor is to be stopped, the inlet valve is first closed, then the unloading valve in the pipe H is opened, and finally the motor is stopped.

Title: Improvements in or relating to pneumatic tyres
IPC: B60C5/20
Filed: 1940-03-16
Abstract: 545,492. Tyre valves. CAMPBELL, G. F. March 16, 1940, No. 2638. [Class 135] An inflating valve assembly for use with pneumatic tyres in which the inner tube is divided into two chambers by a partition having a length equal to half the circumference of the tube comprises a non-return valve mounted in a casing clamped in an aperture in the partition, said casing being detachably secured to a manually operable sleeve carrying the usual tyre inflating tube. The partition valve comprises a conical valve member 18 mounted in a seat-carrying member 16 clamped to the partition by a nut and flange and loaded towards its closed position by a spring 20 engaging a head 21a and by a flexible strip 22 provided with ports 23 and secured to the partition below the valve. The seat-carrying member has a screw-threaded socket adapted to be engaged by a screwed extension on a manually operable sleeve 12 screwed into the usual stem clamped in an aperture in the wall of the inner tube. When the socket and extension are in engagement a projection on the extension engages the head to hold the valve off its seat so that air forced past the usual valve insides 13 in the sleeve 12 can pass through the valve and inflate the lower chamber and also permits the use of a pressure gauge to test the pressure in the inflated chamber. When the sleeve 12 is manipulated to detach the seat carrying member it brings a shoulder 15 into contact with a packing washer 11 to prevent leakage and permit air passing the valve insides to inflate the chamber above the partition. In this position the flexible strip 22 prevents the valve chafing the inner tube.
