Patent GB-1113686-A (GB)
Title: Improvements in or relating to tantalum thin film electrical components
Inventor: HOBBS RICHARD ERNEST
IPC: H01C7/00
Filed: 1964-10-23
Abstract: An electrical component of the tantalum thin film type is equipped with terminating contacts by preparing contact areas on a substrate prior to deposition of the tantalum by sputtering or electron beam evaporation.  Chromium is vapour deposited from two sources simultaneously through a molybdenum mask on to the heated substrate, then commencing before deposition of the chromium is complete, and continuing for some time after it finishes, gold is vapour deposited from a single source, and therefore over a smaller area than the chromium, through the same mask. Nickel is next vapour deposited through a mask in contact with the substrate on those parts of the gold film which will form the contacts and a tantalum layer between 500<\>rA and 4500<\>rA is vacuum deposited or sputtered on to the substrate and contact areas.  A resistor track is formed on the tantalum by a photo-resist method and the nickel is dissolved in ferric chloride, the tantalum over-lying it being removed with it to expose the gold.  The substrate may be glass, a ceramic, a metal with an oxide coating, or an oxide-coated semi-conductor.

Patent GB-1080603-A (GB)
Title: Crimped filaments
IPC: D02G1/12
Filed: 1965-10-13
Abstract: A crimped tow of filaments capable of spontaneously and irreversibly extending (1-30%) in length is prepared by passing a preheated, moistened and drawn tow of shrinkable synthetic linear condensation polyester, e.g. polyethylene terephthalate, or modified copolyester (having birefringence of at least 0.15 and a crystallinity of less than 35%) through a stuffing-box crimper wherein the filaments are heated by injected steam or water at a temperature of 85-250 DEG C for not more than two seconds.  The tow is subsequently dried at a temperature of 60-100 DEG C.  Stapled fibres, which may be mixed with shrinkable fibres, are spun into yarn which is heated, by boiling water and/or dry heat, in one or more stages (perhaps combined with dyeing) before and/or after weaving into fabric to induce spontaneous elongation (and perhaps some shrinkage) of constituent fibres and resultant L-bulking of the yarn and/or fabric.

Title: A Circuit Arrangement for Automatically Tuning a Communication Apparatus.
IPC: H03J5/24
Filed: 1967-09-27
Abstract: 1,190,459. Automatic frequency control systems. GENERAL DYNAMICS CORP. 27 Sept., 1967 [14 Nov., 1966], No. 44076/67. Heading H3A. A radio receiver is tuned by comprising the frequency of its local oscillator (54 or 56, Fig. 2) with a reference frequency to derive an error signal controlling the frequency of the local oscillator and also the tuning of tuned circuits in a R.F. amplifier (via line 26, Fig. 1, not shown), the error signal including a coarse tuning component which changes at a rate proportional to the frequency error. In Fig. 2 signals from the local oscillator are fed through amplifier 62 to a double balanced phase detector 64 supplied with the reference signal and providing outputs at the sum and at the difference frequencies, the latter being selected by filter 68. The beat frequency output is shaped into pulses (72) and fed to a thirteenstage binary counter (illustrated in Fig. 3, not shown) which provides a D.C. output proportional to its count, thereby constituting a staircase generator (76) which advances more and more slowly as frequency equality is approached. This D.C. output provides a coarse tuning voltage which is fed to amplifier 70. If the counter completes its count it actuates a bistable 78 which feeds a band selection voltage generator 38 which changes the frequency range by means of an electronic switch 58 selecting the local oscillator to be used and by means of a further switch (34, Fig. 1, not shown) selecting the required R.F. amplifier. The beat frequency output from filter 68 may also be fed to a peak voltage detector (not shown in Fig. 2) which is arranged to decouple the aerial (10, Fig. 1) from the receiver until the frequency is locked. The output of filter 68 also represents phase error and is amplified (66) and added to the coarse tuning voltage in amplifier 70 which controls varactor diodes (125, 126, Fig. 4, not shown) in the local oscillators 54 and 56 to vary the oscillator frequency. The electronic switch 58 may comprise two pairs of diodes (134, 142 and 136, 140, Fig. 4) one or other of which is conductive according to whether the output from unit 38 is positive or negative; the conductive pair short-circuit one oscillator 54 or 56 and couple the other to the output amplifiers 60 and 62.

A net downward pressure due to fluid flowing through different sized seats 14, 18 opposes an upward force due to spring 10. The valve may have the same sized seats with the inlet at 13 or at 17, the load pressure at 19 then being dependent, directly or inversely respectively, upon the current supplied to the coil 5.

Patent GB-450743-A (GB)
Abstract: 450,743. Skips. SKIP COMPAGNIE AKT.-GES., B³rohaus Burg, Essen, Germany. Oct. 28, 1935, Nos. 29724 and 29725. Convention dates, Aug. 8 and Aug. 24. [Class 78 (iv)] Skips are provided with internal antibreakage flaps, the movement of which is controlled by fluid pressure. Fig. 1 shows one arrangement in which the raising of an arm 8, projected through a slot in the side of the skip in the charging position, by operating the piston in the compressed air cylinder 12, lifts the flap 3 from its hanging position below the pivot 4 to the position shown, in which it receives the first portion of the charge from the hopper 2. By opening the cylinder 12 to exhaust and controlling the rate of exit of the air, the flap 3 can be lowered gradually under the increasing weight of the load until it finally regains its vertical hanging position in which it closes the slot in the side. The control of the compressed-air cylinder may be effected by mechanism linked to or working synchronously with the mechanism for opening and closing the hopper door. The arm 8 may also be locked in its inoperative position and only released by the bucket being brought into position at the charging-station. Fig. 3 shows a modification in which the movement of the piston in the cylinder 12 positions a lever 20 pivoted at 19 so that it projects into the path of a lever 17 pivoted at 16 on the skip. The lever 17 rotates the pivot 4 through the medium of the arm 13 and so raises the flap 3. In this construction the piston in the cylinder 12 may be actuated after the skip has been brought to rest and may be worked in synchronism with the opening of the hopper door. Fig. 5 shows a construction in which an interchangeable compressed-air cylinder 39 is carried on an extension of the skip and acts on the piston through a pipe 40 to raise or lower the member 34 about the pivot 35. The control valve 42 is fitted with an operating-lever 43 either moved automatically by means of contact stops or by hand. It is stated that the exhaust from the cylinder 37 can be used to drive compressors for recharging the cylinder 39.
