Title: Equipment testing systems
IPC: G08C25/02
Filed: 1975-11-10
Abstract: 1480085 Selective signalling FERRANTI Ltd 10 Nov 1975 [9 Nov 1974] 48607/74 Heading G4H [Also in Division H4] Monitoring apparatus comprises first means to be responsive to command signals and to periodic timing signals to be operative during a first part of each timing signal period to pass a command signal state to equipment to be monitored, second means to be responsive to conditions of the equipment to produce, to the output of the first means, a return signal indicative of whether the equipment has operated in response to said command signal state passed by the first means, and third means operative during the remaining part of the timing signal period for comparing the return signal with said command signal state, the output impedance of the first means being higher during the remaining part than during the first part of the period. In Fig. 2, the periodic timing signal is applied at 28 to tristate gate 26 the output 31 of which sees low and high impedance during the first and remaining parts of each period, respectively. A "1" or "0" command is applied to gate 26 at 27 and passed during the first part via 26, 31 and 25 to one of lines 17-20 and one of lines 21-24 to select (by coordinate addressing) and control a ferrite phase shifter associated with one of a matrix array of dipole radiator elements of a phased array antenna. In Fig. 3, terminals 14, 15 are connected to the two addressing lines for the phase shifter 13. The command pulse at 14 goes via a high impedance input gate 35, and monostable 36 to an amplifier 37 the output of which has the same polarity as the command pulse at 14 (by virtue of the lower input at 47). The amplifier output saturates the ferrite at 39 in one sense or the other, a search coil 40 and comparator amplifier 41 reversing a bi-stable 44 if there is any change of state. The bi-stable output is supplied via resistor 45 and terminal 14 back to point 31 (Fig. 2) for check comparison in a gate 29 (during the "remaining part" of the timing signal period) with the command pulse at 27. More than one phase shifter may be provided per dipole. Other applications are mentioned.

Abstract: 1477642 Glass fibre resin composites PILKINGTON BROS Ltd 4 Oct 1974 [22 Oct 1973] 49060/73 Heading D1R [Also in Division B5] A glass-fibre reinforced resin composite is prepared by producing non-continuous glass filaments from molten glass and spraying onto the filaments, immediately after their production, a size composition adapted to protect the filaments against abrasion and containing a film-forming agent which produces a degree of interfilament bonding, forming the filaments into a fibrous glass mat, applying a settable synthetic resin to the mat and compressing the impregnated mat to produce a composite with substantially no voids. The filaments are produced by steam blowing using a multiple tipped bushing or by centrifugal spinning and have a diameter of 10 to 30 microns. They are sized by spraying with an aqueous dispersion of polyvinyl acetate, a silane coupling agent and a lubricant (three being specified) to deposit 2% by weight dry solids. The filaments are collected on a conveyor to form a mat. In example 1 the mat is dried then sprayed with an aqueous slurry of partly polymerised polyester resin, calcium carbonate filler and tbutyl benzoate catalyst and bed in between sheets of polyethylene film through compression rollers to form a "prepreg". Portions were moulded under pressure at 150‹C for 2 minutes. In example 10 the slurry is replaced by powdered epoxy resin. Laminates. The mat of example 1 is collected after spraying with slurry and a plurality of superimposed mats pressed between metal plates and then hot press moulded. Alternatively three impregnated mats are superimposed in a mould, catalysed polyester resin without filler is poured on and the laminate is hot press moulded.

A door closing and holding device 10 comprises a tubular housing 26 defining a chamber 34 closed at one end by a disk 74 with a slot 76 therethrough, a connecting arm 20 formed of flexible strips 52 which passes through the slot and which at one end is operatively connected to a door 12 by a bracket 18 and at its other end is pivotally connected between bifurcated arms of a piston 36 slidably disposed within the housing, and a compression spring 62 around the arm with one end against the disc and the other received by a sleeve 42 on the piston. The flexible strips, made of e.g. spring steel or polypropylene, have spaced apart portions which are flexed towards each other on passing through the slot 76 and thus retard the opening of the door. If the door is stopped in a position after the apex 56 of the spaced portions has passed the slot, it is held in this position (Fig. 6, not shown) but closes under the action of the spring if given a slight push. The door is also held in the fully open position (Fig. 7, not shown). The rate of closing of the door is controlled by controlling the rate of escape of air through an orifice 32 by means of an adjusting screw 78 threaded in an opening in a boss 30, a sealing washer 44 being retained in the housing by an end rib 48 of the piston.
