Abstract: 968,111. Fire alarms. J. STEVENSON.  Nov. 16,1961 [Sept. 28,1961], No. 34877/61. Heading G4N. A fire alarm device comprises the combination in a ventilated holder 15 of a dry cell battery 3, a bell or the warning element (such as a lamp or buzzer) 5 and a thermostat switch 9 which is normally open but is adjusted to close whenever the ambient temperature exceeds a preselected figure and reopens when the temperature falls below that figure; these elements being wired together so that closing of the switch energizes the warning element. A push button switch 7 is connected across the thermostat switch to allow the operation of the battery and bell to be tested.

Abstract: 1,159,706. Welding by fusion. URAGA JUKOGYO K.K. 4 Aug., 1966 [2 Oct., 1965], No. 35049/66. Heading B3R. In an electrogas welding machine in which melt retaining shoes 46, 63 are supported by a carriage movable up the gap between the workpieces 10, 11, the shielding gas, e.g. carbon dioxide or argon, is fed to an expansion chamber 51 rigidly mounted on one of the shoes 46, the chamber having an outlet opening 52 through which gas exits to the welding zone and an opposite transparent window 53 through which the arc may be viewed. The carriage is suspended from a chain passing over a block to a counterweight. The block is carried by a crane and mounts a motor arranged to drive the chain to raise the carriage. The latter comprises a main carriage 18 having guide wheels 37, 38 engaging the gap and a lug 69 passing through the gap to engage in a slot in an auxiliary carriage 68 on the opposite side of the workpieces 10, 11. The shoes 46, 63 are water cooled copper blocks. The rear shoe 63 has crossed slots 64, 65 engaged by a T-bar 66 having a pivoted head 67 the bar being pivotally connected to the auxiliary carriage 68 . A swivel-pin 70 on the bar 66 is connected to the main carriage 18 with the interposition of an adjustable spring 75. The lower end of the main carriage 18 is provided with rollers engaging the work and permanent magnets holding the rollers against the work. The front shoe 46 is connected by a vertical hinge 47 to a frame 110 horizontally pivotable on the main carriage 18. A spring loaded plunger 85 on the main carriage engages the frame 110 to press the shoe 46 against the workpieces 10, 11. An electrode reel, feeding device and welding head 29 are mounted on the main carriage 18. The head 29 is frictionally held in a bracket 29a also frictionally held. The bracket 29a and the head 29 are adjustable by levers 61, 62.

Title: Improved road structure
IPC: E01C5/10
Filed: 1958-10-31
Abstract: 896,127. Paving blocks; roads. DELTA-WEB ROAD & FOUNDATIONS Ltd. Oct. 31, 1958 [Nov. 7, 1957], No. 35076/58. Classes 87(1) and 107. A road structure comprises a series of triangular sections placed together to form a continuous mosaic road surface and joining members at the corners of the triangles connecting each triangular section to its neighbours. The joining members are supported by the ground and are of such height that they at least partly support the road sections and at least partly transmit the road load to the ground. An aperture extends through each joining member whereby sand may be directed to its underside. As shown in Fig. 2 triangular section 1, an underside view of which in shown in Fig. 3, has a surface section 3 built up on weight carrying beams 5 through which pass post-stressing reinforcing rods in holes 10. . At their corners the sections are provided with projections 7 engaging in recesses 8 in the bases 9 of joining members 2. Joining members 2 rest on slabs 12 placed on the ground with, if necessary, a layer 13 of sand therebetween to allow of levelling of the road surface. The edges of the sections 1 are provided with grooves 16 to take a sealing strip or bitumastic or similar filler to seal the road against ingress of moisture. In the embodiment shown in Fig. 2 the joining members are of such height that the sections are held off the ground. In a further embodiment, Fig. 5, both the joining members and the sections rest on the ground and provision is made to prevent the sections being lifted out of engagement with the joining members. The upper part of the joining member is formed by a metal sleeve 22 connected to the concrete base 23. With the sections in place a split ring 24 is inserted around the sleeve 22, the split ring pressing downwards on to shoulder 28 on the sections and upwards on to shoulder 26 of the sleeve 22 to prevent relative displacement of the section and the joining member. A removable plug 30 within sleeve 22 permits adjustment of the height of the road by removal or addition of earth from or to the ground beneath the joining member.

A pointer 22 is moved through gearing (Fig. 5, not shown) about the dial axis upon rotation of the hand wheel 24 in correspondence with the bodily rotation of the shoot and the hand wheel is turned to bring the pointer into alignment with the representation of the channel to be serviced. A ring member (Fig. 4, not shown) concentric with the dial carries three pointers W, X, Y corresponding to the different radii on which the channels are located and rotates upon operation of the hand wheel 40, whereby the lower hinged end of the shoot is moved to the required radial distance by turning the hand wheel 40 until the pointer corresponding to the radius of the selected channel is brought into alignment with the pointer 22. The shoot is closed, i.e. the lower hinged end is brought to lie within the main part, by turning the hand wheel 40 until a further pointer Z on the ring member is in alignment with the pointer 22. Fig. 8 shows the apparatus set for servicing channel S. Lines 21 on the dial 20 indicate a zero position of the shoot.

Abstract: 641,277. Liquid-fuel burners. BORDE, J. Dec. 31, 1947, No. 35245. Convention date, April 11, 1946. [Class 75(i)] An adjustable burner for liquid fuel comprises a main fuel container 9, Fig. 3, into which opens a carburettor jet body 7, and a carburettor case 15 having a jet adjusting pin 6 projecting into the jet orifice 1, Fig. 1, the pin 6 being provided with a coned part 8 which co-operates with the orifice 1 to regulate or close the jet. The pin 6 is carried by a dished part 5 which serves as a flame-trap and is fastened by resilient arms 4 to the wall of the case 15; and an excessive vapour pressure in the container 9 acts on the conical part 8 to press the pin 6 upwardly against the pressure of the resiliently mounted part 5, thus enlarging the jet orifice 1 and allowing the escape of the excess gas. The case 15 is screwed upon the jet 7 so that the pin 6 may be adjusted axially. To facilitate starting an auxiliary chamber 10 is loosely mounted in the fuel chamber 9 beneath the jet so that the liquid in the vicinity of the jet body 7 may become vaporized more rapidly when the part of the body 7 outside the chamber 9 is heated as by a lighted match.
