Title: An improved machine for vulcanising a sole to a boot or shoe length
IPC: B29C35/00
Filed: 1950-01-18
Abstract: 673,184. Hydraulic machines and presses. COTURNO SOC. ANON. Jan. 18, 1950 [Feb. 11, 1949], No. 1373/50. Class 69 (ii) [Also in Group V] A shoe upper on a last 14 is vulcanized to a sole on a patterned press plate 24, by moving jaws 19 laterally to engage the upper on the last and then raising the plate 24 against the last. The jaws and plate are moved towards the last by supplying pressure fluid to cylinders 27 and 6, respectively. The plate moves upwardly only when a predetermined pressure is exerted by the jaws on the upper. The jaws are returned by springs, Fig. 2 (not shown), and the plate 24 is lowered by gravity and by springs. The plate has an electric heater 26. In operation, a motor is started to operate a pump 42, Fig. 6, to pump fluid from a tank 44 through non-return valves 45, 49 and pipe 55 to close the jaws against the last. When the jaws are closed, the pressure in the pipe 55 builds up until it causes plunger 57 to rise and open a valve 61 which allows fluid to pass through valve 50 and pipe 56 to the cylinder 6 to raise the plate 24. When the working pressure in the cylinder 6 is reached, it may be kept constant by any suitable device. After vulcanisation, valve 54 is opened, by a clockactuated solenoid or bv manual operation of lever 62, to discharge cylinders 27, 6 through pipes 55, 56, valves 51, 54, and pipe 63 to the tank 44. The valve 51 acts to prevent fluid from the valve 49 flowing to the cylinder 6 before the jaws have exerted their predetermined pressure on the upper, and to allow fluid to flow to cylinders 27 to compensate for any leakage in the cylinders during vulcanization. The valves constitute a distributor 48. Two or more machines may be operated from the same fluid pressure apparatus. The pistons 29 of the cylinders 27 have cooling fins 31 to dissipate the heat from the plate 24. An accumulator may be used instead of the pump. A contact manometer may be provided to keep the pressures within fixed limits or following predetermined variations, and to operate the machine automatically.

Title: Equipment for and method of operating diesel engines with gas oil and petroleum gas
IPC: F02B11/02
Filed: 1973-01-11
Abstract: 1415252 Regulating I C engine liquid and gas fuel supplies SNAMPROGETTI SpA 11 Jan 1973 [14 Jan 1972] 1620/73 Heading F1B An injection pump 4 for delivering gas oil to a diesel engine 1 has a delivery regulating rack 12, and a valve 24 for controlling the delivery of L.P.G. in vapour form to the engine is controlled in conjunction with the rack such that the valve is opened progressively only after the rack has reached a position corresponding to an intermediate engine power output, e.g. 70% of maximum power. The linkage between the accelerator pedal 14 and the rack 12 includes a lost-motion spring device 48 which permits depression of the pedal when further movement of the rack to increase fuel delivery is prevented by a stop operated by a piston 29. The stop blocks further rack movement when the valve 24 begins to open, a plate 46, Fig.3, on the linkage engaging a stop 45 on the valve actuating rod 44 to open the valve. The supply of gas from a tank 15 through a pres sure reducer and engine cooling water heated vaporizer 20 to a Venturi 26 in the engine intake pipe 2 is additionally controlled by a solenoid valve 19 which is opened when a switch 34 is closed and a switch 40 operated by the piston 29 is closed. The switch 40 is closed when the piston 29 is in a rack blocking position due to the supply of air under pressure from a line 30. A solenoid valve 31 in the line 30 is opened when a switch 35 is moved from a position closing the circuit of a warning light 37 to a position closing the solenoid circuit. The solenoid circuit is closed when the engine cooling water is sufficiently heated to evaporate the L.P.G. in the vaporizer 20. The relationship between accelerator pedal depression and movement of the rack 12 and plate 46 may be adjusted by an adjuster 53 which positions a linkage pivot 50.

Abstract: 508,713. Stuffing - box packing. BACH, E., and KLEIN, A. Jan. 19, 1938, No. 1733. Convention date, Jan. 28, 1937. Addition to 507,066. [Class 122 (v)] The tension of a coil spring 9 surrounding a shaft packing 7 is varied in accordance with temperature variations by means of a bi-metal element or elements 11. A number of bi-metal strips 11 of V shape are attached to one arm of a ring 3 adapted to position the packing in a casing 2. Change of temperature causes the free ends of the strips 11 to deform and press the spring up the inclined face 8 of the packing 7, thereby increasing its tension. Strips 11 may be replaced by arcuate strips secured at one end to the outer arm of member 3 or by an undulated ring-shaped member disposed between the spring and member 3. The bi-metal elements may be so arranged that increase in temperature produces either an increase or decrease in spring tension.

Title: Improvements in or relating to electron discharge devices
IPC: H01J43/08
Filed: 1941-02-10
Abstract: 547,945. Electric discharge apparatus. BOSCH, F. J. G. VAN DEN, TAPP, E. T. J., and VACUUM-SCIENCE PRODUCTS, Ltd. Feb. 10, 1941, No. 1811. [Class 39 (i)] The cathode and control grid assembly for electron discharge apparatus such as the electron multiplier described in Specification 547,971, thermionic valves, and cathode-ray tubes, consists of a tubular member 10, Fig. 4, with a heating element 11 in the form of a zig-zag wire housed in a recess in a steatite &c. plate 13, in which it is clamped by another plate 14. Asbestos pads 24, housed in sockets in the plate 13, press the ends of the cathode against the plate 14, which is provided with a flared opening 40 for the passage of the electron beam. A shallow circular depression 36 in the plate 14 houses the control grid 31 whose frame wires 30 are seated in registering grooves 29, 39 and 28, 38 in the abutting plate surfaces. The grooves 28, 38 are preferably large enough to accommodate thermal expansion and contraction and constructional tolerances. Grooves and apertures are provided in the plates for the leads. In a modification, Fig. 5, the cathode is a plate 41 overlying the recess in the plate 13, and held in abutment therewith by pads 24 mounted in sockets in the plate 14. The plate may have flanged ends or sides or both which may be sprung into the undercut sides of the recess, in which case the pads may be dispensed with. The heating element 11 is pressed into contact with the inner surface of the plate by an asbestos pad 42. The control grid frame wires 30 lie in grooves in the plate 14 and are spread apart to tension the wires by arched spings 44 abutting against the underface of the plate 13. The spacing of the cathode and grid is regulated by washers 18 around the clamping bolts 9, and the spacing between the plates may be closed by packing or by providing a registering lip and groove on the plates. In an alternative arrangement the grid and cathode are supported against the face of the upper plate 13 by arched springs bearing on the lower plate. Fig. 7 shows an arrangement in which both plates 13 and 14 have electron emission apertures 49, and a grid is provided on both sides of the cathode. The grids are housed in recesses 43 in the plates, the supports 30 being spaced by resilient pads 48 and lying in grooves 47 which allow for thermal expansion or variations in size. The ends of the cathode are clamped between narrower and shallower parts of the recesses. The walls of the openings and the outer faces of the plates may be glazed or have a metallic coating at a suitable potential to control the field distribution in the neighbourhood of the cathode. The Provisional Specification refers to Specifications 540,893 and 543,106. Specification 516,621 also is referred to.
