Title: Method of and apparatus for manufacturing toothed belts
IPC: B29B15/00
Filed: 1972-03-28
Abstract: 1387313 Moulding toothed belts INDUSTRIE PIRELLI SpA 28 March 1972 [6 Oct 1971] 14415/72 Heading B5A In a method of manufacturing toothed belts of elastomeric material reinforced with a tensionresistant insert, a number of uniformly spacedapart bars 28 are applied transversely to a rubberized fabric band 12 the ends of which are then joined together, to provide a sleeve over which a cord 37 providing said insert is wound; a layer of elastomeric material 13<SP>1</SP> is then applied to the winding and the resultant sleeve removed from its support whereupon the sleeve is moulded and cured in stages, in each of which a group of bars is removed from a sleeve portion which is then pressed between platens 48, 49, Fig. 7, one of which is appropriately grooved. The fabric band 12, to which the bars are applied, is supported on adjustably spaced grooved rollers 19, 20 carried by a frame 7 rotatable on a shaft 6; the bars are appropriately spaced by members 31 inserted into their ends and attached to a flexible rope 32, and are attached, in the first instance, to the band by clips 34. When the sleeve has been formed to embrace the rollers 19, 20 a further roller 17, Fig. 1, forces the bars and adjacent portions of the sleeve into the grooves in the roller 19 which is rotated. The frame 7 is then rotated about its shaft 6 to receive a winding 37 which may be metallic, glass or synthetic fibre. An adhesive is applied to the winding and the layer 13<SP>1</SP> then applied whilst the roller 19 is driven via gears 16, 23. The rollers are then brought together and the sleeve assembly removed and subjected to moulding and curing by the platens. Those edges of the sleeve which carry the clips 34 are not received by the platens and are subsequently removed.

Title: Improvements in and relating to Thermo Regulators and Alarms.
IPC: G05D23/24
Filed: 1917-10-09
Abstract: 120,412. British Thomson - Houston Co., (General Electric Co.). Oct. 9, 1917. Electric alarm systems.-In a temperature regulator or alarm for an electric.heating device such as a radiator, the function of which is the production of heat, or a controlling resistance such as a vacuum lightning arrester, in which the production of heat is incidental, the current to the heating device 10 is supplied from a generator 11 through the arms of a wheatstone bridge A, the resistances being subject to the temperature of the heating device and having different temperature co-efficients so that a balance is obtained at the required temperature of the heating device. At any other temperature a current tends to flow, but a unidirectional cell 20 is included in the circuit of the heating device to allow the passage of the current in one direction only. In the arrangement shown in Fig. 1, the heating device 10 is connected directly to the wheatstone bridge, of which the opposite arms 12, 13 have a positive temperature co-efticient and may be made of iron, while the other arms 14, 15 have a negative temperature co-efficient, and may be made of silicon or an electrolyte. Other arrangements are described in which the current is supplied to the heating device from an independent source, and the wheatstone bridge is used to control the current to one or more switches controlling a further switch in the circuit of the heating device. Thus, in the arrangement shown in Fig. 5, as soon as the temperature of a vacuum lightning arrester 31 reaches a predetermined value, a sufficient current flows through the relay 21 to actuate a switch 23 by which the current is shunted from the lightning arrester.

Title: Improvements in and relating to rectifier installations
IPC: H02M7/15
Filed: 1933-05-20
Abstract: 412,398. Converting. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. May 20, 1933, No. 14680. Convention date, May 20, 1932. [Class 38 (ii).] Relates to rectifying arrangements using grid controlled discharge devices and consists in supplying the grids with a control potential having a frequency which is a multiple of the supply frequency. In the arrangement shown in Fig. 1, the grids of the rectifier Glare connected together and are supplied with a control frequency which is six times the supply frequency. This is obtained by selecting the sixth harmonic from the D.C. output of an auxiliary rectifier G2 fed from the 6-phase secondary of a transformer T2. The transformer T2 is constructed as a phase-shifting transformer so that regulation can be effected. In a modification, to permit of regulation over a wider range, the grids are arranged in two groups, each group being fed with a control potential having a frequency three times the supply frequency, the supplies to the two groups being arranged 180‹ out-of-phase. In a further arrangement, the grids are in three groups and the control potentials have a frequency twice that of the supply frequency. To obtain automatic voltage regulation the phase of the voltage on the primary side of the grid supply arrangement is varied in dependence upon the rectifier current. Specification 395,632 is referred to.

Filed: 1926-06-14
Abstract: 269,004. Bean, O. U. June 14, 1926. Oil gas.-Combustible gas is generated by superheating steam and dissociating it by a catalyst into its constituents which are then mixed with hydrocarbon vapour, the mixture being subjected to a succession of expansions and contractions with increase of temperature whereby the hydrogen and the hydrocarbon vapour combine to form a permanent gas. Water is supplied from a tank 13 through a conduit 22 to coils 23, 26 of increasing cross-section, in which it is converted to steam which is superheated and dissociated by passages through a heated nickel wire screen or other metal catalyst 27. The hydrocarbon is fed from a tank 12 through a pipe 21 to a tube 30 surrounded by a tube 31 to which the dissociated steam is supplied. The vaporized hydrocarbon and the dissociated steam are heated in expansion chambers.32 to 1100‹ F. and pass by a conduit 35 to coils 37 maintained at 1200‹ F. in which the permanent gas is formed. The gas passes to an outlet 39 for purification or to an outlet 61 for use for the burners 71, 72 which are also supplied either with liquid or gaseous fuel from a tank 11 through a pipe 73 or with fuel from an extraneous source through a pipe 60. Pyrometers 57, 58 are provided in the steam and gas coils respectively through the medium of an automatic control, to control the supply of heating fuel and constituents for gas making. Carbon black mav be obtained and delivered through the outlet 39 by suitable adjustment of the temperature and supply of materials.

Title: Improvements in or relating to braking devices applicable to tractor-trailer vehicles
Inventor: EDGE STANLEY HOWARD
IPC: B60T13/24
Filed: 1951-06-25
Abstract: 698,912. Tractor-trailer braking mechanism. CLAYTON DEWANDRE CO., Ltd., and SCAMMELL LORRIES, Ltd. March 27, 1952 [June 25, 1951], No. 15046/51. Class 103 (i). A braking arrangement for tractor-trailer vehicles includes a control valve device embodying hydraulic and vacuum devices arranged for operation by a common actuator to cause application of the tractor brakes by hydraulic pressure and vacuum release to enable automatic mechanical means, normally held inoperative by a vacuum cylinder to apply the trailer brakes. Braking of the tractor vehicle is effected by depression of the pedal a which operates the hydraulic cylinder d through linkage b, j, l ; the hydraulic fluid being transmitted to the tractor brake cylinders by a conduit m. Depression of the pedal a, acting through linkage b, i, p, controls the communication between a conduit f, leading from a source of vacuum, and a conduit g leading to a vacuum servo cylinder h on the tractor or trailer vehicle. The piston-rod r is connected to a pivoted lever s, linked at t to a pull rod u attached to the normal spring system for applying the trailer vehicle brakes. A piston-rod v linked to a ivotped lever 8 at q projects from a slave cylinder o . which is supplied with hydraulic fluid from the cylinder d. The slave cylinder 0 keeps the motion of the vacuum servo cylinder h in step with the operation of the valve e and prevents the piston in that cylinder from surging forward when the vacuum is applied. To enable the trailer brakes to be applied, without application of the tractor brakes, whilst the trailer is being coupled or uncoupled from the tractor vehicle, a lever x is provided to effect withdrawal of the kingpin of the brake linkage by operation by cable from the driver's cab.
