Title: Improvements in or relating to hydraulic gears
IPC: F15B13/01
Filed: 1962-04-30
Abstract: 957,851. Hydraulic apparatus. ISTAG A.G. April 30, 1962 [April 28, 1961], No. 16419/62. Heading F1P. An hydraulic system comprises a reversible delivery pump 1 communicating over a closed circuit having two liquid conduits 44, 58 and 45, 59 with an hydraulic motor 2, a slide valve 3 having a sliding plunger 32 which communicates at each end with a separate one of the conduits so as to be responsive to a difference in pressure existing in the conduits and effect a connection between the conduit at lower pressure and a conduit 57 between the valve housing 33 and a reservoir 15, and a check valve 34, 35 opening towards the motor provided in each of the two liquid conduits, the sliding plunger acting as an opening member for the check valve in the conduit at lower pressure. The plunger has its ends in chambers 42, 43 connected by the portions 44, 45 to the pump 1, the check valves, which consist of balls 34, 35, normally closing the portions 44, 45 from the other portions 58, 59 of the conduits leading to the differential-area piston motor 2. A reduced central portion 51 of the plunger is associated with the conduit 57 leading to the reservoir 15 and lands 17, 18 on the plunger provided with edges 55, 56 control communication between the chambers 42, 43 and the conduit 57; ribs 54 support the plunger during its movement. Extensions 47, 48 on the ends of the plunger act as opening members for the check valves. When the pump is rotating in the direction A, fluid pressure in chamber 43 moves the plunger to the left, the movement first connecting chamber 42 to the conduit 57 so that the portion 44 of the conduit which supplies fluid to the pump is connected to the conduit 57 leading to the reservoir. Further movement of the plunger causes the extension 47 to open the check valve 34 to permit fluid from chamber 26 of the motor to pass to conduit 44. The fluid pressure in chamber 43 opens the check valve 35 to permit fluid pressure to move the piston 24 to the left, excess fluid, because of the differential areas of the piston, exhausted from chamber 26 passing through conduit 57 to the reservoir. When the pump is rotated in the opposite direction, the plunger moves to the right and the fluid, additional to that exhausted from the chamber 27, pumped to chamber 26 is drawn through conduits 45, 57 from the reservoir. The arrangement compensates for any losses caused by leakage from the system. When the pump is stationary; the plunger takes up a central position and both check valves 34, 35 close to lock the piston 24 in position. In the event of a heavy load on the piston when it is in its locked position causing excessive pressure in the chambers 26, 27, adjustable pressure relief valves 70, 71 are provided connected by conduits 60, 61 to the reservoir.

Title: Improvements in or relating to tungsten filament lamps
Inventor: BOWTELL JAMES NORMAN
IPC: H01K1/54
Filed: 1955-06-08
Abstract: 797,010. Electric incandescent lamps. GENERAL ELECTRIC CO.. Ltd. Sept. 7, 1956 [June 8, 1955], No. 16480/55. Class 39(2) A vacuum type electric incandescent lamp having a tungsten filament designed to dissipate in normal operation a wattage lying between 20 and 75 is provided with a pearshaped glass bulb wherein the diameter of the hemispherical or hemispheroidal end part is not greater than 50 millimetres. The object of the lamp is stated to be the reduction of radio interference, especially in the 30 to 150 Mc/s band, believed to be due to electrons which are emitted from the filament and the wall of the bulb or envelope. Fig. 4 shows one example of a lamp described as "pearshaped", other examples being illustrated in Figs. 2 and 3 (not shown), all however, having the common feature that the ratio of the overall length to the aforesaid diameter lies within the range 1.0 to 1.8. The optimum diameter for a 40 watt lamp is about 45 millimetres. Preferably the filament is arranged in a castellated configuration on an imaginary cylinder lying approximately evenly about the diametral plane of the hemispherical end 1 of the envelope at right-angles to the lamp axis, the ends of the filament being supported by leading-in wires 9, and intermediate points by pig-tails 11 of which some have ends set into a glass button 12 at the end of the arbor 8 and others have ends set into the arbor itself. In order to reduce the effect of bulk blackening and a possible shortening of the life of the lamp, due to the reduction in the size of the bulb employed, the composition of the getter medium used in the manufacture of the lamp differs from that normally used, and care is taken to ensure that the getter is applied only to the filament and not to the filament supports. One example of getter comprises a suspension of 10 grams of phosphorus and 50 grams cryolite per litre of methyl alcohol suspension medium, together with 20 cc. of necoloidine as binder. The getter may be applied to the filament by spraying before it is mounted on its supports, or by brushing after mounting.
