[Also in Division H1] A layer comprising a mixture of SiO 2  and P 2 O 5  is deposited on substrates 16 of N-type Ge to act as a mask during a subsequent acceptor diffusion process (see Division H1). Using the apparatus shown a tube furnace 12 is initially flushed with an H 2 : N 2  mixture while the substrates 16 are heated to about 500‹ C. for 5 minutes. Oxygen is then bubbled through a liquid 20 which contains a source of Si, e.g. tetraethoxysilane or triethoxysilane, and a source of P, e.g. trimethyl or triethyl phosphate, and is passed over the Ge substrates 16. Additional oxygen is also introduced via the valve 36. During deposition the substrates 16 are maintained at 400-550‹ C. If it is also desired to deposit a layer of SiO 2  on the substrates 16, the phosphorus source is omitted from the liquid 20.

An inverter 2 comprising discharge devices with grids pulsed from 7 to determine the output frequency has condensers 6, 8 connected in parallel and series respectively with the output winding of transformer 3, the first of which functions as a commutating condenser, whereby it supplies from a constant direct voltage source 1, an alternating voltage at 5 which varies little with load and powerfactor changes. By arranging the condensers 6, 8 in parts which can be switched in manually or automatically in dependance on load by switch 10. the possible load range with constant output voltage may be increased, Fig. 5. To vary the output volts, a further output transformer 11 with tapped primary may be provided, and there may also be a further commutating condenser 14 connected in series with a variable resistance 13 across the inverter anodes. The arrangement of the auto transformer 9 allows higher voltage to be impressed across the condensers.

Abstract: 1311507 Mixing EI DU PONT DE NEMOURS & CO 18 May 1970 [19 May 1969] 23976/70 Heading B1C [Also in Division B8] A gravity-flow solids blender, e.g. for blending granular polyethylene, comprises a storage vessel 10 from which withdrawal conduits 11 extend to traps 29 leading to a common collector 12, each trap having a passageway for the direction of a stream of gas through the trap whereby controlled withdrawal of solids into the collector is effected. The vessel 10 has a loading line 9 and solids are withdrawn through the conduits 11 from positions in the vessel at a distance from the wall of the vessel which is not greater than a quarter of the distance from the wall to the centre of the mass of solids within the vessel. The withdrawn solids pass through a line 14 and can be recycled to the vessel through a line 14' or removed through a line 15 by operation of a flap valve 16, the line 14' discharging tangentially into a receiver 21 and the solids passing from this to the vessel 10 through a rotary feed valve 22. A blower 18 produces a vacuum in the line 14' and a separate source of vacuum is applied to the line 15, and a vent 23 keeps the vessel 10 at atmospheric pressure. Air enters the traps through air flow restrictors such as valves 31 or orifices, Fig. 2 (not shown), and air also enters the apparatus through a filter 24. Overall vacuum control is provided by a manually or automatically operated bypass valve 32. In a modification, Figs. 3 and 4 (not shown), the traps are disposed within the collector 12. In another embodiment, Figs. 5 to 7 (not shown), compressed air is supplied to the line 14 by a blower and a rotary valve 45 is disposed between the collector 12 and the line 14. Compressed air is supplied to the traps from the blower or from an external source via a manifold or individually. In a modification, Figs. 8 and 9 (not shown), a manifold feeds compressed air to traps which are outside the collector 12 through jets which have individual manual control valves, an electric solenoid control valve being provided in the main supply line to the manifold. The outlet of each jet is within 1" to 2" from the face of the pile of solids retained in the respective trap when the gas flow is not operating.

Abstract: 251,845. Maxted, H. P., and Alford &. Alder (Engineers), Ltd. Sept, 25, 1925. Force-transmitting mechanism; compensating for wear.-The cross-shaft for operating the brakes on a pair of vehicle wheels is mounted on the axle so as to prevent interference with the braking action by the springing of the vehicle particularly in the case of front wheel brakes in which a differential braking action as between the brakes on the two wheels is effected during steering. Means are described for permitting relative angular adjustment of the cross-shaft in relation to the brake-operating shafts proper actuated thereby. The cross-shaft 8 mounted by brackets 9 on the axle 2 carries a. pair of arms 7 each of which is connected by a link 6 to an arm 5 on an operating shaft 3 of the brake. Each shaft 3 is connected by a universal joint. 4 to the brakeoperating means, the joints 4 being displaced from the wheel pivot axis so that the brakes automatically tighten or slacken with the deflection of the wheels. The link 6 is screw-threaded into a pin 12 on the arm 7 ,and carries a thrust collar 13 for engagement with a pin 14 on the arm 5 through which the rod 6 passes. The effective length of the link 6 and thus the angular relationship of the shafts 3, 8 can thus be adjusted by turning the head 11, the collar 13 being grooved transversely for engagement with the pin 14 so as to lock the link in the adjusted position. The shaft 8 may be disposed on the rear side of the axle 2 instead of tube front as shown in Figs. 1 and 2, in which case the connections for the link 6 are modified so that it acts in tension.
