Title: Improvements in or relating to sputtering apparatus
IPC: H01J37/34
Filed: 1965-08-20
Abstract: Fig.1 shows apparatus wherein material is sputtered from an ion target 94 on to a substrate 98.  The sputtering chamber can be evacuated at 17 and ionizable gas such as argon can be supplied from a tank 28, e.g. to a pressure of 1 micron.  A filament 41 is heated to supply electrons which move through a cooled electron guide 32 towards an anode 68 and create an ion plasma 131 along an axis 77. The ion target 94 is electrically biased so as to attract ions from the axial plasma. A solenoid 116A, having a controllable field, controls the density of ions attracted by the target 94 and the sputtering of material from the target and so controls the density of the resulting film on the substrate.  The strength of the magnetic field is controlled by a variable resistor 120 and the position of the field can be altered by hooking hooks 118 into different links of suspending chains. The solenoid may be suspended in a tilted position. Figs. 2 and 3 (not shown) illustrate apparatus where a shaped nozzle at the end of the electron guide 32 and a shaped anode (157) cause the ion plasma to be in the form of a curtain.  Fig.4 (not shown) illustrates apparatus wherein the plasma axis is arranged to be horizontal.  Fig.6 (not shown) illustrates a modification wherein ion plasma can be created between a central position (205) and one or other of two (or more) anodes <PICT:1123563/C6-C7/1> (181, 181') in the coating of substrates (190, 190') by sputtering from targets (95, 95').

Abstract: 452,080. Modulating systems. GORDON, W. G., Flora Street, Sutherland, and MAKINSON, R. E. B., 10, Watson Street, Neutral Bay, both in New South Wales, Australia. Dec. 28, 1935, No. 35910. Convention date, Dec. 29, 1934. [Class 40 (v)] Frequency modulation of oscillations generated by a negative resistance, e.g. a back - coupled valve, is effected by the variation of a positive resistance in the circuit. As shown in Fig. 1, a negative resistance Ra is in parallel with a coil L, and a positive resistance R2 is in parallel with a condenser C, and the two sets are connected in series with each other and with a resistance R1 which is variable to regulate the frequency of the generated oscillations. The positions of the resistances R1, R2, Ra may be interchanged. In another arrangement shown in Fig. 3b, the negative resistance Ra is in series with the coil L, the positive resistance R2 is in series with the condenser C, and both sets form parallel branches across the variable resistance R1. In this arrangement also, the three resistances may be interchanged in position. The resistance R2 should be equal to the absolute value of the negative resistance Ra and to the square root of L /C. Formulae are given in the Specification for the oscillation frequency for each arrangement. Fig. 2 is a circuit embodying the Fig. 1 arrangement. The negative resistance comprises a back-coupled triode V2 in parallel connection with the coil L. The variable resistance comprises a pentode valve V1 with modulating voltage applied to its control grid from a potentiometer E1. It is shunted by a resistance r and is in series with the condenser-resistance combination C, R2 across the negative resistance V2.

Title: An adjustable pitch propeller
IPC: B64C11/32
Filed: 1964-09-03
Abstract: 1,074,873. Feathering propellers. CESSNA AIRCRAFT CO. Sept. 3, 1964 [Sept. 3, 1963], No. 36180/64. Heading B7V. [Also in Divisions E2 and F1]  An aircraft propeller has blades 15 mounted in a hub 10 and rotatable about their pitch axes by a piston 22 through connecting-rods 28. The piston is biased to the feathered position against a stop 33 by springs 35 and the centrifugal force on a counterweight 16 and is moved towards the fine pitch position, against flanges (31, Fig. 2, not shown) by hydraulic pressure from a pump 40 (which is driven by the propeller, engine, or otherwise) transmitted through a valve 45, controlled by a governor 44 which gives a high pressure when the engine is running slowly, and lever 47, then through the propeller shaft 12 and a hollow piston-rod 23, 26. According to the invention, when the engine is stopped the piston 22 is returned to the fine pitch position by the reduction in the force on the weight 16 and by movement of the valve 45, e.g. by the governor; and held near there to facilitate restarting by latches (50, Fig. 2, not shown) on the piston 22 arranged to engage the flanges (31). A supplementary piston (60) is fitted within the piston 22 and is urged to the left by springs (61) and to the right by hydraulic pressure transmitted through an orifice (56) in the piston 22. When subjected to hydraulic pressure the latches are held out of engagement with the flanges (31) by another flange (72) on the supplementary piston (60). The springs (61) are stronger than the springs 35, relative to the respective areas of their pistons, and so, as the pressure falls, the piston (60) is first urged to the left by the springs (61) until ramps (66, 67) on the piston (60) and latches (50) engage when the latches are pivoted into engagement with the flanges 31.

The constant speed and volume motor 21 has a shaft 24 on one end carrying a flywheel 25 and at the other end connected to the rotor of a variable volume bypass controller 26, the eccentricity of the rotor being variable by a lever 37 or a pressureresponsive device 38 in the line to a power takeoff 33 to vary the, flow through, and hence speed of, the power take-off 33. All the fluid passing through the power take-off 33 and the by-pass controller 26 passes through the power take-off 29 which is thus supplied with a constant volume of fluid and rotates at a constant speed. Both power take-offs may be of the rotary turbine type. The distributer has a disc 49 in which are parallel bores 54, 55 and crossed bores 56, 57, the disc being rotated at the end of each stroke of the pump pistons by a cam-and-follower device 52 on the shaft 24. The pistons 11, 12 are reciprocated by the prime movers 1, 2 which may be driven by internal combustion. During downward movement of the pump piston 11, fluid beneath the piston passes through a pipe 13 to the lower end of cylinder 10 to move the piston 12 upwardly, fluid above that piston passing through a pipe 17 and one of the parallel bores into a pipe 19 leading to the motor 21. At the end of the stroke of the piston, the disc 49 of the distributer is rotated so that, during the upward movement of the piston 11, fluid above that piston can pass through a line 16 and one of the crossed bores 55 to the line 19 and motor 21, so that the motor 21 and power take-offs always rotate in the same direction. In other embodiments, two constant-speed take-offs may be arranged in series or in parallel and the pistons of the engines 2, 3 be arranged to reciprocate in the same cylinder, the rods of the pistons being connected by links to the pump pistons which are arranged parallel to the engine pistons.
