IPC: G05D23/02
Filed: 1959-02-20
Abstract: 870,363. Valves. GENERAL MOTORS Ltd. Feb. 3, 1960 [Feb. 20, 1959], No. 5911/59. Class 135. [Also in Group XIII] In a valve for an I.C. engine cooling-system, a piston 6 adjustably secured to a valve seat member 15 extends through a guide 5, having a recess containing at least one synthetic rubber 0-ring 8, into a housing 2 to which the guide is secured and which contains microcrystalline wax. The wax melts near the temperature at which the housing, together with a valve 21 secured to the guide 5, is moved away from the member 15, by the expansion of the wax, against the action of a spring 22. A gasket 9 closes the ring recess while a recess, at the top of the guide 5, also containing an 0-ring 11, is sealed by a press-fit dish 12. The end of the piston 6 in the housing may be tapered. A bleed hole 26 in the valve 21 permits air escape when filling but when water is circulating, a weight-loaded pin 27 is lifted to close the hole. The Provisional Specification describes also a valve in which the end of the wax housing secured to the guide is seated in the central opening of the valve member and in which the volume of the housing is determined by adjusting the amount by which the end wall is inwardly dished.

Abstract: 491,714. Photo electric control of fuel supply for burners. PILLINGER & CO., Ltd., G. C., and PILLINGER, G. C. March 1, 1937, No. 6026. [Class 40 (iii)] [Also in Group XI] Relates to automatic control systems for heating-burners, of the kind in which the fuel supply to the burner is cut off when the flame is extinguished, by the action of a photoelectric cell which is normally exposed to light from the flame. According to the invention, an arrangement for utilizing the stream of combustion air to cool the cell and to keep it clean consists in supporting the cell 3 in a tubular chamber 2, intersected by a conduit 1 conveying air to the burner, in such a manner that the cathode 4 is optically exposed through the conduit to the burner. Conveniently, the tube 1 may be mounted alongside the burner nozzle and connected to the main air duct so as to byepass some of the supplied air, Fig. 2 (not shown) ; or an independent air current may be passed through the tube 1.

Filed: 1950-03-10
Abstract: 715,463. Velocity-modulated tubes. SPERRY CORPORATION. March 10, 1950 [March 26, 1949], No. 6097/50. Class 39(1) [Also in Group XL(b)] A klystron comprises a plurality of resonators formed as cylindrical holes in a single block of conductive material, or in the form of cylindrical members traversing a framework of conductive material, and a rectilinear passage for the electron beam is provided to intersect each of the resonators, the axis of this passage being perpendicular to the principal axes of all the resonators. In the three-resonator klystron of Fig. 3, the resonators 7, 8, 9 are formed by bores in the block 1. Posts 3, 4, 5, 6 located in the passage for the electron beam carry grids 18, 19, 20. The grids 18, 19 are formed by a set of single triangular vanes for optimum transmission of beam current. whereas the grids 20 are formed by a set of double triangular vanes 56, Fig. 3A, for optimum coupling. The drift tube defined by post 4, Fig. 5, is longer than the drift tube defined by post 5 for optimum operation. In assembly, clamping screws 55, Fig. 3, hold the posts in position until they are brazed or soldered to the block 1. Recessed bores in the side of the block receive coupling members 14, 15, 16. The resonators are closed at their ends by diaphragms 26, 27, 28, Fig. 5, formed in side plates 24, 25. Outer plates 31, 32 carry differential screw assemblies 33 for flexing the diaphragms and so tuning the resonators. In a modification the plate 32 may carry the coupling members, instead of tuning assemblies. In another embodiment, Fig. 6 (not shown), the resonator bores are not carried right through the block. In the klystron of Fig. 8 the resonators consist of cylindrical members 90, 91, 92 within a framework composed of plates 107, 108, 109, 110. Cooling fluid is circulated in the space between these plates and the resonator members. The plate 108 forms one end closure for the resonators and carries the coupling members 120, 121, 122. The other ends of the resonators are closed by flexible diaphragms which are acted upon for tuning by the screw assemblies 33 carried by an outer plate 118. Provision may be made for gang-tuning the resonators. The multiresonator klystron may be operated as a straight or synchrodyne amplifier.

Title: An improved method of and apparatus for coating and finishing flooring
IPC: B27G1/00
Filed: 1920-03-02
Abstract: 163,827. Dittmar, E. C. March 2, 1920. Coating-machines.-In one passage through the machine, the upper surfaces of strips of flooring are cleaned, covered with a. " filler " wiped transversely, burnished, and coated with varnish. A strip is passed through an horizontal guideway in the feed-table 2, and is cleaned by the brush 4 on its way to the feed-rollers 8, 9 which are operated from the power shaft 7 as indicated in Fig. 1. The upper roller 9 is adjusted so as to exert sufficient pressure on the flooring to cause the latter to engage the spurs with which the lower grooved roller 8 is fitted. The strip is then gripped between the conveyer 22 and the pressure roller 24 and receives a coating of filler as it passes under the tank 25, which is agitated continuously by the rod 36 pivoted eccentrically at the shaft 7. The filler tank is mounted on a block 29 faced with rubber, and is supported by the pivot 29<1> and the adjusting-screw 35 when not resting on a piece of flooring. The pressure applied to the flooring may be varied by moving the weight 32 along the extension 33 of the block 29. A rectangular framework 40 is supported in front by rod 42, and has two pairs of bearings. One pair engages and rests on the shaft 38 at the back of the machine, while the other pair supports the shaft 45 carrying the wiper 49, which is a wheel fitted with leather flaps on its circumference. The shaft 45 is rotated through the agency of a pulley 46, band 47 and a fixed pulley on the shaft 38, which is operated from the power shaft 7 by means of a band 39. A second wiper 49<1> is geared to the shaft 38 in a similar manner, but it rotates in the reverse direction and is not in alignment with the first. Brass burnishers 52 are gripped by holders 51 and their pressure on the flooring is regulated by means of the weight 54. Varnish from the tank 61 supplies a tray 57 which is fitted to a movable framework 56, Fig. 4, the pressure of which on the flooring is adjusted by means of a weight 65, and brushes 63 distribute the varnish as it is applied by the felt 58 attached to the bottom of the tray 57. The filler employed is composed of ground silex, linseed oil, Japan drier, and colouring-matter with a small amount of a thinner such as turpentine.

Abstract: 556,253. Platinum alloys; heat treatment. MOND NICKEL CO., Ltd., and PFEIL, L. B. May 15, 1942, No. 6647. [Classes 72 and 82 (i)] [Also in Groups XXVII and XXII] Sparking-plug electrodes 1, 8 resistant to attack by lead are made of alloys composed principally of one or more metals of the platinum group, of which at least the unsupported parts have a fibrous microstructure when they are assembled in the plugs and ready for service. Suitable alloys containing 4 per cent. to 5 per cent. tungsten, 20 per cent. iridium, 10 per cent. rhodium or 2 per cent. molybdenum, or platinum-tin alloys, or ruthenium may be added to a platinumtungsten alloy. The alloy is subjected to severe cold working to produce a wire of fibrous microstructure, and re-crystallization due to heating of at least the part of the wire which forms the unsupported part of the electrode is prevented during the production of the wire and its essembly in the plug, e.g. by keeping the temperature below about 950‹ C. In an example, platinum-tungsten alloy is reduced hot to a rod 0.2 inches square, annealed at 1050‹ C. for 15 minutes, and reduced in stages by cold working to 0.046 inch diameter round wire; the alloy may be held at a temperature of 800‹ for 10-15 minutes at 0.09 inches prior to further reduction in size. The electrode 8 is spot-welded to the plug body 10 and the electrode 1 is set in a metal 4 having a melting-point no higher than that of silver, a glass seal 7 being provided around the metal wire 5.
