Abstract: Superposed layers of gold and silver (or predominantly silver) are deposited on germanium or silicon bodies in the following manner to provide ohmic contacts thereto.  A silicon body comprising zones of different conductivity types so disposed as to make it suitable as a transistor (see Group XXXVI) is masked, enclosed in a vacuum chamber provided with heater filaments loaded with silver and a gold antimony alloy (0.1% by weight antimony) respectively and heated to 500 DEG C.  The gold loaded filament is first energised to evaporate gold on to the wafer through the mask to provide a series of groups of three parallel elongated gold layers.  When the layers are about 200 thick the silver loaded filament is energized and the other switched off as soon as silver begins to deposit.  The amount of silver is limited so that its complete evaporation results in layers 5 m thick.  A further layer of gold is provided by re-energizing the gold loaded filament.  In an alternative method, after deposition of the first gold layer the silver and gold are evaporated simultaneously, the evaporation of the measured amount of silver being so much more rapid that while it lasts the layer is essentially of silver. When the silver is exhausted the gold continues to evaporate to provide the outer layer.  When germanium is used instead of silicon it is maintained at a temperature of only 390-400 DEG  C. during the deposition process.  Specifications 809,642, 809,643, 821,832 and 821,834 are referred to.

Title: Improvements relating to "seal-off" gas blast electric circuit breakers
Inventor: ROXBURGH ALBERT
IPC: H01H33/56
Filed: 1960-01-12
Abstract: 949,563. Gas-blast switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 6, 1961 [Jan. 12, 1960], No. 1124/60. Heading H2B. In a gas-blast switch a gas control valve assembly supplies to the contact chamber high pressure gas to open the contacts and extinguish the arc and also supplies lower pressure gas to the chamber to maintain the contacts open when the high pressure gas is shut off. In the arrangement shown, the opening of the switch is initiated by moving a rod 4 downwardly to move a valve element 2 downwardly to open a port 5b and close a port 27. The lower pressure source is now connected to the contact chamber (not shown) via pipe 7, port 5b, pipe 5 and pipe 1a. The rod 4 in its downward movement opens a servo valve 17, through a link 8 and a prop 9, and vents highpressure gas from behind a valve piston 3 to atmosphere so that high-pressure gas acting from a reservoir 1 through ports 26 on to the top of the valve piston 3 moves the piston downwardly against the bias of a spring 22. High-pressure gas now flows from the reservoir 1 through the ports 26 and the pipe 1a to the contact chamber. Pressure gas acting through passages 2b in the valve element 2 moves a piston 12, which moves the prop 9 against the bias of a spring 14 to release the servo valve 17. This valve 17 is reclosed by a spring 18 and leakage of high-pressure gas to the space below the piston 3 causes the piston to move upwardly under the bias of the spring 22 and shut-off the supply of high-pressure gas to the contact chamber, the contacts being held open by the supply of the lower pressure gas from the pipe 7. Upward movement of the rod 4 and valve element 2 recloses the port 5b to shut-off the lower pressure gas and permit the contacts to close, the prop 9 and the piston 12 being returned to the position shown by the spring 14. In a modified arrangement, Fig. 2 (not shown), the valve 3 is directly operated by linkage connected to the rod 4, the linkage being subsequently released by the piston 12.

Abstract: 708,633. Reservoir pens. KOVACS, T. Jan. 16, 1951 [Feb. 2, 1950], No. 1219/51. Class 146(3) A feed bar 3 is provided with a tapering air duct 7 having tapering capillary ink grooves 8 on the side adjacent the knib 4, the air duct being in communication with annular chambers 11 and 12 connected by a capillary groove 18, these chambers having a greater' capillary potential than the air duct at their level. Longitudinal chambers 9 and 10 are provided in the feed-bar for storing ink overflowing from a reservoir 2. Air to replace ink used is supplied to the reservoir 2 through the air duct 7, an annular groove 16, and a longitudinal groove 17, but when the chambers 11 and 12 are filled with ink, a gap 15 communicating with the groove 16 is filled with ink, thus preventing air entering the reservoir. In these circumstances, ink filling the chambers 9 and 10 and chambers 11 and 12 must be emptied before replacement air can reach the reservoir 2. The sizes of the ink duct 7 and chambers 9, 10, 11 and 12 are such that overflowing ink fills the air duct 7 last, while ink from the air duct 7 is used first, then ink from the chambers 9 and 10, then ink from the chamber 11, and finally ink from the chamber 12.

Temperature control means associated with each room unit are provided to effect heat transfer between the circulating heat exchange medium and the air in the individual rooms only upon a demand for heating when heating fluid is available and only upon a demand for chilling when chilled fluid is available. The heat exchange medium alternately heated and cooler is bled off to the units 16 in rooms A, B, C via T-fittings 28 and valves 36. The latter are actuated by controls 38 themselves controlled by temperature-responsive bulbs 40, 42 responsive to the temperature in the individual rooms and the temperature in the main conduit 10 respectively. The heater 14 and the chiller 12 are connected alternately into the conduit 10 by two three-way valves 18, 100. The valve 100 responds to the temperature of the returning fluid at 104 and the valve 18 is controlled jointly by a timer 18, and by the temperature drop between the outgoing and returning fluid as senser at the points 114 and 116. The latter sense the relative heating and cooling needs and determine the relative durations of hot water circulation and cold water circulation. The valves 36 may be replaced circulating pumps, or may be omitted and the heat transfer controlled solely by variation of the speeds of the fans 22. In the case of air induction units for the room units control of the heat transfer is effected by dampers. The heater and the chiller may be by-passed for periods intermediate those of heating and cooling.
