IPC: G08G1/082
Filed: 1969-06-11
Abstract: 1277095 Road traffic signals OMRON TATEISI ELECTRONICS CO 11 June 1969 [20 June 1968] 29668/69 Heading G4Q In a system for controlling a plurality of local controllers, each local controller includes a radio receiver whereby the local controllers are synchronized with one another and generate desired traffic pattern instruction signals in response to standard frequency and time signals broadcast by, e.g., station MSF at Rugby. The system obviates the conventional master controller and the cables connecting this controller with the local controllers. In more detail, each local controller includes offset and split circuits and a time discriminator circuit coupled to its radio receiver, this discriminator circuit generating timing signals. A programmer responsive to the timing signals generates the traffic pattern instruction signals corresponding to the time of day, these latter signals together with the generated timing signals being applied to control means for controlling the operation of the split and offset circuits. One embodiment of the system utilizing counters is described with reference to a drawing accompanying the Specification.

A manifolding appliance of the kind comprising a base, a clamping member mounted on the base and carrying two clamping elements adapted to releasably retain one of two superposed forms having a transfer layer between them in its operative position and each having a manually engageable operating member, is provided with means adapted to retain each of the two clamping elements releasably in both their operative and inoperative positions. As shown, the clamping member 10 is adjustably mounted on the base 11 for movement transversely as described in Specification 722,079 and comprises a main housing 12 for a pair of form clamping elements or bars 14, 15 and a central housing portion 13 for a shorter carbon clamping bar 20. Each clamping bar 14, 15 has at each end an integral lug 16 mounted for vertical sliding movement in a groove 17 in an end member 18 of the housing 12 and each bar has clamping pins 19 slidably mounted at intervals, the pins being spring loaded as described in Specification 688,490. The bar 20 is similarly guided at the ends of the housing 13 and has a resilient carbon engaging clip 22 with resilient projections 23. The bars 14, 15 and 20 are retracted to their inoperative positions by pairs of tension springs 24 anchored to pins 25, 25 and 6 and are operated by means of cams 27, 28, 29 mounted side by side on a central trunnion pin 26 and having an operating thumb piece 31. Each cam 27, 28 and 29 is generally circular but having a straight dowell 30 resting, in inoperative position, in flat engagement with its corresponding bar 14, 15, 20, the thumb pieces 31 then lying to one side 33 of an opening 32 in the housing 12, 13 through which the tops of the cams project. Movement of a thumb piece 31 to the opposite edge of the opening 32 will cause the corresponding cam to bear on its corresponding bar to press it downwardly into engagement with the form below, the dowell 30 then being completely out of engagement with the bar and the cam retained in the new position by the frictional spring applied pressure. Each cam may be operated independently, but the three thumb pieces 31 may be simultaneously engaged to move the cams simultaneously. The underside of the housing 12, 13 is closed by a plate 34 having an opening 35 for the clip 22 and rows of holes 36 for the pins 19. Specification 675,206 also is referred to.

Title: Method of operation and operating device for gas turbine prime movers, in particularfor ships
IPC: F02C3/04
Filed: 1937-11-01
Abstract: 493,174. Gas - turbine plant. COMPAGNIE ELECTRO-MECANIQUE. Nov. 1, 1937, No. 29799. Convention date, Oct. 30, 1936. [Class 110 (iii)] The manoeuvring of a ship, fitted with gas turbines and a combustion air compressor driven by a separate gas turbine with its own combustion chamber, is carried out by means of compressed air expanding in a turbine, which may be a separate machine or part of the main prime mover. The divided main propelling turbine T1, Fig. 1, receives hot gases from the combustion chambers D<1>1 and D<11>1 which are supplied with fuel at R<1>1 and R<11>1 respectively. Combustion air, supplied by the compressor C driven by a separate gas turbine T3 with its own combustion chamber D3, is heated in the heatexchanger E1 by the exhaust gases of the turbine T1. The air supply to the combustion chamber D3 is heated in the heatexchanger E3 by the exhaust gases of the turbine T3. The ship may be manoeuvred by shutting off both of the fuel supplies R<1>1, R<11>1 and driving the machine Tl with compressed air controlled by one of the valves V<1>1, V<11>1. An astern turbine T2 is supplied with compressed air controlled by a valve V2. A combustion chamber may be fitted in front of turbine T2 if continuous operation of this machine is required. The turbines T1, T2 may be replaced by (1) a special manoeuvring turbine, (2) parts of the main turbine, or (3) part of a group of main turbines. The starting of the plant is effected by means of a small auxiliary motor adapted to drive one of the compressor units at low speed until its burners can be ignited, and the other machines may be started with air supplied by this compressor. A device, Fig. 2, for maintaining the gas temperature at the inlet of the main machines constant and as high as possible consists of a two circuits (1), (3) controlling the fuel supply to the compressor and main turbines. Oil under pressure is supplied at J and passes through the diaphragms dl, d3 to the servomotors P1, P3, operated by the pressure in the circuits (1), (3). These circuit pressures are controlled by the leak-off orifices A1, A3. If the lever Q is operated to open or close the orifice A3, the compressor turbine T3 speeds up or slows down and the quantity and pressure of the air supplied to the combustion chambers of the main machines are altered. This in turn causes the diaphragm Y, connected to a Venturi tube in the air supply line, to open or close the orifice Al which controls the amount of fuel supplied to the main machines. The diaphragm X, connected to a Venturi tube in the fuel supply line to the main machines, will then operate to reestablish equilibrium of the orifice Al. A temporary increase or decrease in temperature during acceleration or deceleration is allowed by a device consisting of an auxiliary orifice in circuit (1) operated by the lever Q together with a time delay device attached to the rod R1 connecting diaphragms X, Y.

Title: Pneumatic tyre and wheel assemblies
IPC: B60C5/12
Filed: 1970-06-20
Abstract: 1359461 Lubricating contacting interior surfaces of a tyre on deflation DUNLOP Ltd 9 June 1971 [20 June 1970] 30027/70 Heading B7C To enable running of a pneumatic tyre 1 and wheel 2 assembly with the tyre deflated, the assembly includes enclosing means, e.g. 4, for a lubricant for lubricating those interior surfaces of the tyre which contact each other on deflation, to thereby prevent tyre destruction due to frictionally generated heat, the enclosing means being adapted to automatically release the lubricant into the tyre interior on deflation. The enclosing means may be constructed such that lubricant release is caused by abrasion of, or impact on, the means by an interior surface of the deflated tyre, as in the case of the means 4 and 39 shown in Figs. 1 and 12, which comprise rupturable sachets, e.g. of PVC or rubber, and the means 14 shown in Fig. 7, which comprises a plunger 17 displaceable to release the lubricant. Alternatively the enclosing means may be of pressure sensitive construction such that it releases the lubricant as soon as the tyre pressure falls below a predetermined level, as in the case of the means 20 in Fig. 8, which is pressurized with air so that it bursts when the predetermined pressure level is reached, or may be of temperature sensitive construction such that it releases lubricant when the temperature in the tyre rises above a predetermined level due to heat generated on deflation. The enclosing means may be attached to an interior surface of the tyre as shown in Fig. 1, or to the radially inner or outer surface of the wheel rim base as shown in Figs. 7 and 8, or to a saddle 36 on the wheel rim as shown in Fig. 12. Numerous other constructions of enclosing means are described and illustrated in the Specification. The saddle 36 shown in Fig. 12 serves to prevent displacement of the tyre beads 37 from their seats on the wheel rim when deflation occurs. As alternative or further means to prevent such displacement the wheel may have a flat base rim without a well, which rim may be a crimped rim as shown, e.g. in Fig. 1, i.e. a rim initially formed with a well which is then closed up after a tyre has been mounted on the rim, or may be a rim split to permit tyre mounting and demounting. The assembly may be one in which the tyre has been secured to the wheel rim by swaging the rim over the tyre beads. The tyre may have an aspect ratio of between 30% and 75% and its tread width may be greater than the distance between the tyre bead retaining flanges on the wheel rim. The lubricant used in the enclosing means may be a liquid as described in Specification 1,359,467 or a solid, e.g. graphite or French chalk. Specifications 1,359,462, 1,359,463, 1,359,464 and 1,359,465 are also referred to.

Abstract: 1354441 Flaring tubes; tube expanders ZAKO ROHRVERBINDUNGEN GmbH & CO KG 27 June 1972 [29 June 1971] 30121/72 Headings B3Q and B3J [Also in Division F2] A double flange is formed at the end of a metal tube lined with plastics by forcing a mandrel, which may be a pipe connection member, into the free end of the tube to expand it, the mandrel &c. having a collar with a face shaped to form the double flange and a tapering circular surface at least partly toughened to hold back the plastics lining as the mandrel enters the tube, so that the lining is pushed back from the tube end. In one form, a tube 12, Fig. 3, having a plastics lining 11, is expanded by a tapered mandrel 22 having a toughened annular area 23 and a peripheral rib 24 engaged by the plastics lining when the tube is initially placed upon the mandrel, Fig. 1 (not shown). A split holder ring 13 having a toughened surface 14 grips the tube 12 and has a frusto-conical surface 15 engaging a corresponding surface in a ring 17 tightened to the position shown by turning a threaded spindle 18. At first, the rib 24 holds the plastics lining 11 while the tube end 40 is slidden to abut the end face of an annular groove 25 in the mandrel, Fig. 2 (not shown). On further rotation of the spindle 18, the plastics lining 11 slides over the rib 24, as shown, and the annular groove 25 deforms the tube end 40 to form the double flange 27 shown. The mandrel 22 &c. is withdrawn, and the double flanged tube end 40, Fig. 5, may be inserted over the tapered and roughened end of a pipe connector 29, where it is held by tightening a nut 28. Alternatively, a seal ring (43), Figs. 10-12 (not shown), may surround the hose of the end of the pipe connector 29, the outer end edge (44) of which is bevelled. To form a further modification, the double flange 27, Fig. 8, at the end of the tube 12, is forced over an 0-ring 39 lodged against a peripheral lip 37 around a pipe connector 38 to seat within a groove 41, into which it is crimped. In yet another form, the double flanged end of the tube 12, lined with plastics 11, is formed as the tube is forced on to a tapered mandrel 49, constituting a part of a pipe connector, and having grooves 51 engaged by the lining. A nut 52 is tightened to secure the mandrel 49 against a seal ring 48 in a pipe connector 45.
