Title: Improvements relating to fluid pressure braking apparatus for rail and other vehicles
IPC: B60T8/32
Filed: 1935-01-22
Abstract: 437,155. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Miller, R. E., and Cotter, G. L. ; Wilkinsburg, Pennsylvania, U.S.A.) Jan. 22, 1935, No. 2138. Convention date, Jan. 23, 1934. [Class 103 (i)] In automatic fluid-pressure brakes for railways, the braking effort is controlled by a device 14 responsive to the rate of retardation of the vehicle, the extent of this control being dependent upon the reduced pressure obtaining in the train pipe 38. The supply of fluid from the triple valve 10 to the brake cylinder 30 is controlled by a valve 12 operated by fluid supplied by the inertia governor 14, which comprises masses F, R acting against springs 64, the compression of which is dependent on fluid in diaphragm chambers 72 supplied by a valve device 90, 16 controlled by train pipe pressure. The retardation of the train on braking causes either mass F or mass R according to the direction of travel of the vehicle to move away from stop 62 against spring 64 and close exhaust valve 76 and open inlet valve 80 to supply pressure fluid through a pipe 84 to piston 48 which moves a piston 46 either to close brake cylinder supply pipe 56 or open it to exhaust 52. The fall in train pipe pressure acts on diaphragms 92, 94, 96 to close an exhaust valve 20 and to open an inlet valve 130 to supply pressure fluid through a reducing valve 18 to the diaphragm chambers 72 to increase the tension of the springs 64 so that the greater the fall in train pipe pressure and the greater the braking, the greater braking effect will be attained by the inertia governor before it causes the brake cylinder supply to be closed. Pressure fluid from a reservoir 110 acts on one side of diaphragm 96 and through a passage 108 between diaphragms 92, 94. A ball check valve 180 allows release of the brake in case the inertia device should fail.

Abstract: 672,335. Blow torches. LINDE AIR PRODUCTS CO. Jan. 30, 1950 [Feb. 23, 1949], No. 2314/50. Class 75(i) In a blow torch having a combustion chamber fed with fuel and comburant gas. a protective coating of silica is deposited and maintained on the internal wall of the combustion chamber by introducing a compound of silicon into the chamber while the fuel is burning. The blow torch shown, which is used for piercing,4 hole in a mineral mass, comprises a tubular body 11 carrying at its lower end a water-cooled copper nozzle 13 having an internal combustion chamber 15, a throat 17 and a flared discharge orifice 19 for the combustion products. Liquid fuel is pumped from the tank T to the torch and is discharged by an injector 27 through a narrow passage 28 into the combustion chamber. Oxygen, air, ozone or peroxide is supplied by a pipe 25 to the chamber. Cooling water is supplied by a pipe 30 and issues in the form of steam from ports 29 on the periphery of the nozzle. A small quantity of a compound of silicon such as tetraethyl orthosilicate or silicon tetrachloride is dissolved in the fuel and as the fuel burns the compound is deposited as silica on the chamber wall. The quantity of compound in the fuel may be equivalent to between 01 per cent and 10 per cent of silica by weight, a high concentration being used when the burner is started to build up the silica coating. Instead of using a soluble silicon compound silica itself may be suspended in the fuel. A list of suitable soluble compounds is given.

Title: Improvements in or relating to phase shifting arrangements
IPC: G01R25/00
Filed: 1946-01-24
Abstract: 646,364. Phase changers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 24, 1946, No. 2424. Convention date, July 29, 1944. [Class 38 (ii)] A combination of several phase shifters, each having its primary winding supplied with quadrature phase currents at a frequency different from that supplied to the others, has means for simultaneously adjusting the relative angular position of the rotor and stator windings of each phase shifter by an amount having a predetermined relation to its frequency. These amounts may be proportional to the frequency. The arrangements described provide for adjustment at angular rates in proportion to the frequencies. In Fig. 5 the hand wheel 15 drives the phase shifters 25, 27 and 37 through successive stages of gear reduction, the first rotor turning at an angular rate which is ten times that of the second and a hundred times that of the third. These rates are proportional to the frequencies (e.g. 93, 9.3 and 0.93 kc. per second) respectively applied to devices 25, 27 and 37. The movements are indicated by counter 51. The rotor of device 37 can be independently turned by knob 43 which is first pulled forward to disengage detent 45 from hole 49 in driving gear 41. Each stator has two windings S1 and S2, at right angles as shown in Fig. 1, and supplied with currents in quadrature ; they are mounted in slots on a cylindrical insulated support carried by a hollow shaft which can be clamped in any angular position in a split bearing. The rotor windings, made up of coils R1, R2, R3, R4 of large and short span, as shown, connected in series-aiding, are in grooves in a cylindrical insulating support enveloping the stator and carried by driving shaft 9 ; the connections are through brushes 11 and slip-rings 5 and 7 on shaft 9. For the higher frequencies there is an electrostatic shield between stator and rotor. Fig. 4 shows a bridge connection of two phase shifters having stator windings S1-S2 and S3-S4 respectively and rotor windings R and RR.

Filed: 1939-01-25
Abstract: 524,240. Thermionic cathodes. EHRENBERG, W. Jan. 25, 1939, Nos. 2528 and 12579. [Class 39 (i)] Thermionic cathodes for cathoderay or X-ray tubes &c. consist of a disc 3 of electron emitting material such as tantalum, columbium, tungsten or zirconium or coated with an electron emitting material, which is heated by an electron emitting filament 7. The disc is supported by three arms 4 which are inclined to the plane of the disc from a support 5 closed at one end except for the aperture 6 in which the disc is positioned in spaced relation thereto. The heater is a spiral filament 7 connected at one end to and surrounded by a focusing shield 8, the whole being supported from a base plate 9 by three support rods 10. The support and heater are held together by a sleeve 11 with lugs 13 welded to tabs 14 on the plate 9 and provided with slots 12 to accommodate the arms 4 when the support 5 is placed over the upper end of the sleeve. In a modification the sleeve may be omitted and the support 5 directly connected to the plate 9. Alternatively the base may be of mica or ceramic material and the supports for the disc and filament moulded therein. The disc may be concave or convex instead of flat. To avoid variations in the temperature of the plate due to variation in the power of voltage for operating the device, a source is preferred in which the D.C. regulation is such that the maximum power output is substantially equal to that dissipated in the plate to bring it to the required temperature. Specification 338,430, [Class 39 (i)], is referred to.

Title: Improvements in or relating to switching devices for use in high frequency circuits
IPC: H01P1/10
Filed: 1928-01-26
Abstract: 284,293. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Moulton, A. B.). Jan. 27, 1927, [Convention date]. Contacts.-Switches for high frequency circuits are provided with means for compensating the natural capacity between the switch contacts when open, so that the leakage of high frequency current is reduced to a minimum. As shown in Fig. 1, conductors from a source of high frequency current are connected by a double pole switch to conductors 6. 8 connected to apparatus for using such current. The effect of the capacity c<1> between the block 9 and contact 10 is neutralized by connecting an equal capacity m between the blade 9 and the other supply lead 4 so that an equal potential of opposite phase is applied to neutralize that produced by the natural capacity c<1>. Similarly a condenser n<2> is connected between the line 2 and blade 10 to neutralize the natural capacity c<2> between it and its contact 10. Instead of providing condensers for this purposethe natural capacity between the movable contacts and further fixed contacts suitably connected to the working contacts may be employed. Thus, as shown in Fig. 3, the inherent capacities n<1>, n<2> between contacts additional to the working contacts are employed to neutralize the effect of the capacities c<1>, c<2> between the movable contact-members 9, 10 and the fixed contacts with which they co-operate. The switch may be employed to connect an antenna on an incoming line to a suitable receiver and amplifier such as the push-pull amplifier shown, the switch being operated by a handle 30 pivoted at 32 and carrying a cross bar provided with insulating rollers 34 bearing on the ends of the contact springs 9, 10. Where the natural switch capacities and neutralizing capacities are all equal the connections of the supply and receiver circuits may be interchanged.

[Also in Division F1] In an integral hydraulic pump and jack unit particularly for lifting the fork arm of a conventional pallet truck (Figs. 1 and 2, not shown), wherein manual operation of the pump causes liquid from a reservoir 9 to be drawn past a suction valve 34 into a pumping chamber 46 and to be expelled therefrom past a delivery valve 36 to the jack cylinder 52, the valves 34, 36 and an additional valve 38 for limiting the rate of return flow during jack lowering are housed in a single valve block 22 removably screwed into the unit. The valves 34, 36, 38 are shown in their jack raising and holding position, wherein liquid from the reservoir 9 flows through ducts 49, 48 and the suction valve 34 to the pumping chamber 46. From the chamber 46 liquid is pumped through ducts 45, 44, 29, valves 36, 38 and a port 51 to the jack cylinder 52. A control rod 31 screwed into the valve block 22 is rotatable by a lever 42 at the front of the truck, initial rotation opening the suction valve 34 to interconnect the reservoir 9 and the pump chamber 46. Further rotation of the rod 31 maintains the suction valve 34 open and causes an intermediate rod 41 to open the valve 36. The load carried by the jack can then force liquid back through the port 51 and around the valve 38 to the reservoir 9. The valve 38 is in the form of a sleeve loaded by a spring 37 and containing an orifice 40. If the load on the jack is excessive the open end of the sleeve is forced against a seat and the return flow passes only through the orifice.
