In Fig. 4 the piston 110 includes a magnet which acts on an armature controlling a microswitch 109 in the fluid flow control circuit. In an alternative arrangement (Figs. 1 and 2, not shown) the piston magnet controls an indicator and can only be reset on release of ball detents on the removal of the filter which may be of woven wire mesh preferably of stainless steel or may be fibrous material such as fibreglass, asbestos or resin impregnated or coated material. The filter element may be cylindrical, conical, dished or plate shape.

Abstract: 1285058 Knitting-machines S A MONK (SUTTON IN ASHFIELD) Ltd 9 Sept 1970 [9 June 1969] 28971/69 Heading D1C A straight bar machine includes a safety system for the loop transfer elements in which the machine is stopped if collision between two element brackets, or between a bracket and a predetermined part of the machine is imminent. The machine is stopped by earthing bus bars. The right hand V-neck point bracket 14 Fig. 1B is mounted on point bar 16, which carries at its other end a block 35 Fig. 1a bearing a feeler 37. Arranged between the feeler 37 and a bus bar 24, within the block, is a spring. Collision of the bracket with the centre point bracket 10 is prevented by contact of feeler 37 with a collar 39 on the point bar 11. The bus bar 24 is thus earthed. If the point bracket 10 is moved out of action by rotation of the point bar, as shown, a flat on the collar 39 is aligned with the feeler. In this instance inward movement of the bracket is limited when the feeler 37 strikes collar 40. If the bracket 14 strikes plunger 30 attached to part 9 of the machine frame, bus bar 27 is earthed via spring 32. Similar provisions exist for the left hand bracket 13. Collision between selvedge brackets 17, 18 and any other bracket is prevented when plunger 44 earths bars 22, 23 via springs 42 or 41, depending on the conditions during narrowing.

Abstract: 523,828. Launching aircraft. KING, F. W. Jan. 13, 1939, No. 29030. Divided out of 520,948. [Class 4] For securing an aircraft to a launching device, vacuum plates c, d, shaped to conform to the parts of the aircraft, are kept exhausted of air until flying speed is attained. The plates have a soft rubber edging, and intermediate ribs are provided to prevent collapse of the adjacent aircraft covering. The plates are mounted in blocks g slidable upon arms i, h, which are in turn laterally slidable on transverse members b. Automatic release may be provided for by adjusting the degree of vacuum so that the aircraft pulls clear when sufficient lift is obtained. Alternatively, air may be admitted to the plates when a trigger on the launching way encounters a valve lever s. For use on a catapult the drive is taken by a separate thrust block but when vehicles or ships are used for launching, the plates may form the sole connection and the vacuum is destroyed by the pilot opening a valve to admit air through holes in the aircraft surface. Where the launching cradle is submerged while the aircraft is being mounted thereon, plates-covered with rubber may be used.

Copying-telegraphs; thermionic detectors. - In a copying or similar high-speed telegraph employing a modulated carrier frequency, the modulated carrier frequency is changed by means of one or more pairs of amplifying-valves arranged as rectifiers with input circuits E, to which the carrier frequency is applied, in phase opposition and output circuits in parallel across a common external load Ra. The invention facilitates demodulation and suppression of the carrier frequency for retransmitting on a higher carrier frequency. Demodulation is effected by a special rectifying-valve or bv a wave trap S in the anode circuits of the pair of rectifying-valves. The rectifying valves may be enclosed in a single envelope.

The store is thin film, core, or semi-conductor integrated circuit and the faulty elements are located by test programmes and then altered by photoetching, cutting by laser or destroying the magnetic properties by laser heating so that an interrogation signal produces a distinctive response not to be confused with binary 0 or 1. The total number of elements per word roughly equals the word length plus the number of expected faulty elements per word. Reading.-A word is stored in a number of elements including some faulty ones and on interrogation the read signals from the serviceable elements are supplied to a shift register SR1 and the signals from the faulty elements are supplied to a shift register SR2. By successive left shifting of the registers the word is reduced to a continuous word without gaps for faulty elements (Fig. 3, not shown). A device ELL identifies the first L from the left in register SRII. Writing (Figs. 5 and 6, not shown).-A register SRIII containing the same data as register SRII causes appropriate spacing of words for writing by successive right shifts. Parallel operation.-Reading and writing can also be effected in parallel, (Figs. 7 and 8, not shown) by provision of switches S1 to S4 which are set simultaneously by the data in register SRII using the circuitry of Figs. 9 and 10 (not shown). Circuitry is described for giving distinguishing signals for faulty bi-stable elements (Figs. 11 and 12, not shown). Auxiliary store (Fig. 14, not shown).-The addresses of the faulty words in a first store are stored in the non-faulty word locations of a second store using a sequencer. In further embodiments (Figs. 16 to 22, not shown) the delay time of the circuits is reduced by the use of shunting diodes or transistors. Further, a faulty element may be identified by not connecting the element to the read line, and an associative store may be constructed (Fig. 25, not shown).
