Title: Improvements in control systems
IPC: B64D45/00
Filed: 1960-12-22
Abstract: 953,473. Protective arrangements. VICKERSARMSTRONGS (AIRCRAFT) Ltd., and D. I. ROBERTSON. Nov. 30, 1961 [Dec. 22, 1960], No. 44120/60. Heading H2K. In a control system, e.g. a triplicated aircraft autopilot control system, having a plurality of signal transmission channels A ... C for separately transmitting control signals from a common input to a common output, fault detection apparatus comprises a plurality of signal responsive devices C AB , C BC , C CA  to which are applied different combinations of the control signals taken two at a time. Each device C AB , C BC , C CA  produces an output signal in response to a predetermined difference between the two control signals applied thereto. Switch means, including two sets of normally-closed contacts, associated with each channel are operative in response to the simultaneous appearance of output signals from the devices fed from that channel to render that channel inoperative. In the arrangement shown, the switch means comprise electromagnetic relays RAB/2, RBC/2, RCA/2 each having two normally-closed sets of contacts, one set in a path of each of the channels from which signals are applied to the associated signal responsive device. Thus in the event of a fault in a channel, e.g. channel A, device C AB  RAB provides an output to relay which opens 2 its contacts rab1 in channel A and its contacts RCA rab2 in channel B. Similarly relay opens 2 contacts rca2 and rca1 in channels A and C respectively. Channel A is now interrupted whilst channels B and C remain operative. Should the fault be in a signal responsive device or in a relay, none of the channels are interrupted.

Title: Improvements in or relating to microphone mountings for telephony
Inventor: BORRETT WILLIAM GEORGE
IPC: H04M1/19
Filed: 1965-10-22
Abstract: 1,117,367. Mouthpieces. MINISTER OF TECHNOLOGY. 21 Oct., 1966 [22 Oct., 1965], No. 44800/65. Heading H4J. A sound muffler comprises a mask adapted to fit over the mouth and nose and containing a respiratory vent passage and a plurality of acoustically resonant cavities communicating with the vent passage through apertures. The cavities are arranged to form a cylindrical assembly. The cavities and apertures are so proportioned and so placed as to attenuate speech sounds and/or environmental noises passing through the vent passage. In one embodiment (Fig. 1) a face mask 1 contains a cylindrical vent passage sub-assembly 2 and two discs 3, 4 of open cell porous material. The discs 3, 4 support a pressure gradient microphone 5 and have porosity such that normal breathing does not cause an excessive pressure drop across them. Foamed plastics edging 6 provides a sound-proof seal. The sub-assembly 2 (Fig. 2) comprises a cylinder 10 between upper and lower plates 11, 12. The plates 11, 12 are slightly larger than the cylinder 10 and fit tightly within the mask. A vent passage is thereby formed between the cylinder 10 and mask 1. The plate 11 has a cutaway 13 and the plate 12 has a cutaway 14. A bar 15 blocks the vent passage between cutaways 13, 14. Wedge-shaped cavities are formed by radial walls 16 and each cavity communicates with the vent passage through a countersunk aperture 17. In use, speech sounds travel into the vent passage and are absorbed by the cavities and apertures 17. Alternatively, a downwardly extending tube 22 (Fig. 4) fits closely over a helical ridge 24 formed on the outer surface of a moulded plastics tube 23. A helical vent passage is thus provided between tubes 23, 24. Tube 23 is subdivided by discs 25, 28, 29 and by two cruciform sectioned members (26, 27), Fig. 3 (not shown) to form eight resonant cavities, e.g. cavity 18. Each cavity communicates with the vent passage by an aperture 17. Foamed plastics pieces 3, 4 support a pressure gradient microphone 5 and a cable 30 from the microphone passes centrally downwards. In each embodiment microswitches may be fitted in resilient edging 6, whereby the microphone is only operative when the mask is fitted.

Title: Corrosion resistant coating
IPC: C25D3/12
Filed: 1962-12-03
Abstract: Metal surfaces are plated with two coats of nickel containing sulphur, the first coat containing less sulphur than the top coat. The sulphur is obtained from S=O compounds added to the plating bath, and consists preferably of organic sulphonates, sulphonamides, or sulphonimides, the second plating bath containing substantially more than the first and including a brightening agent, e.g. thiourea, selenium oxide and butyne diol, which induces sulphur retention in the nickel plate.

Abstract: 1340233 Filtering thermoplastics BARMAG BARMER MASCHINENFABRIK AG 4 Oct 1971 [10 Oct 1970] 46033/71 Heading BID An arrangement for filtering thermoplastics comprises at least two filters in pots 1a, 1b detachably mounted in a housing having an inlet 4 and an outlet 5 connected to respective ring pipes 6, 7 associated with inlet valves 11 and outlet valves 12 which enable each filter pot to be isolated for removal and cleaning. The arrangement is such that when the valves 11, 12 for one filter are closed, the thermoplastic material still flows around the ring pipes, so preventing the formation of "static melt". Each valve comprises a disc 13, a stem 14 and an extension 9 which, when the valve is closed, fills a short tap line 8 leading to the filter pot so that "static melt" cannot form there. Each filter pot is in two parts 21, 22 which detachably clamp between them the flange 30 of a support 29 for filter sieves 31. The support has radial bores 32 and a displacement body 33 to facilitate the flow of material. Inlet and outlet ducts 24, 25 lead to the outside and inside of the filter and have seals 26 by which fluid-tight connections are made with the tap lines 8 under the action of screws 23. Vent pipes 37, 38 lead to the two sides of the filter and may be connected to a melt container 39, or to a low-pressure source. Each filter pot is housed in its own section of the housing and the sections are secured together by members 2 and 3 in which the ring pipes are formed. (For Figures see next column)
