Title: Multi layer air filter bag
IPC: B01D46/02
Filed: 1978-12-11
Abstract: An air filter comprises a bag (2) the wall (3) of which is air permeable and consists of an inner layer (4) of perforate material, an intermediate layer (5) of fibrous material and an outer layer (6) of bonded material; the inner layer serving as a support for the intermediate layer whilst itself allowing substantially free passage of air, the intermediate layer serving to take up particles entrained in air flowing into the bag, and the outer layer being sufficiently dense to take up particles that have passed through the intermediate layer, and serving as a further support for the intermediate layer. The inner layer may be of nylon net material or of open weave material, the intermediate layer may be a wadding of acrylic yarn, and the outer layer of bonded polyester yarn. When used in industrial gas turbine applications the filter bag may be arranged after a pre-filter, such as an inertial louvre filter or a cleanable panel filter. <IMAGE>
Patent GB-2029657-A (GB)
Title: Measuring pulse frequency
IPC: G01R23/10
Filed: 1978-12-20
Abstract: Pulse monitoring of the number of pulses received over a predetermined metering period, the beginning and end of which advances with respect to time, is achieved by supplying the pulses to a counter (2) which counts the pulses and provides an n-bit parallel output signal indicative of the number of pulses counted; the pulses are at the same time supplied to the forward counting input of a bidirectional counter (3). An n x k bit shift register (4) is provided into which the output signals from the counter (2) are read and shifted at a frequency not less than   <IMAGE> of the maximum expected frequency of pulses to be monitored. Each shift pulse subsequently clears the counter (2). At the same time a signal appears at the output of the shift register (4) and is supplied via a decoding means (6), to the backward counting input of the bidirectional counter (3). The value in the bidirectional counter (3) is therefore dependent at any one time on the mean frequency of pulses received over the preceding metering period, which pulses may be representative of a particular quantity, such as electrical power consumed. The shift register (4) requires a relatively small number of storage locations. <IMAGE>

Patent GB-2036163-A (GB)
Title: Self-locking hinge
IPC: E05C19/18
Filed: 1978-12-22
Abstract: {PG,1 A self-locking hinge for use as a pivotal connector between two pivoted members and adapted to lock the members in a fixed angular relation. The hinge comprises a pair of circular plates that are rigidly affixed to opposite faces of one member and rotatably connected to the other member. The circular plates are used to laterally support both of the members and to guide the other member as it is rotated from a folded position to a fully extended position. The hinge is locked in the fully extended position by means of a locking ring that is slidably engaged with the other member. When such other member is fully extended, the ring engages corresponding locking indentations at the periphery of the circular plates and thereby blocks the movement of the other member in one angular direction. The movement of the other member is blocked in the opposite angular direction due to the abutting of the hinge ends of the members. The members may be returned to the folded position by releasing the locking ring from its engagement with the indentations in the circular plates. The operation of the self-locking hinge of the invention is particularly described with respect to a door security apparatus adopted to engage a door and a floor to resist the opening of the door. A further embodiment uses the self-locking hinge of the invention to provide a means to convert a stepladder to a straight ladder of increased height.

Patent GB-2043472-A (GB)
Title: Toys
IPC: A63H18/02
Filed: 1980-02-19
Abstract: The invention is for a toy in which a vehicle is driven cyclically around a tubular circuit by means of a pneumatic pump 13, and proposes the inclusion of a one-way valve 12 connected between the circuit and pump, this valve normally being open to the circuit, but operable to close the circuit unidirectionally in response to pump actuation. The valve can be of simple flap form with a flap normally suspended across the pump inlet to the circuit, but swung upwardly against an abutment to close the circuit under pump pressure. The circuit can be closed or open, the gap in the latter case preferably being downstream with a largely downward return circuit portion thereafter towards the valve to ensure vehicle inertia to pass through the valve. The vehicle can cross a circuit gap in free flight or be guided, and both these modes can be provided by a common component with valve selection of alternative circuit sections. A duplicated assembly of circuit, valve and pump allows race competition, and gaps in the two circuits can intersect to allow mutual interference between competitors by vehicle collision. Other forms of special features, including interference, are possible. <IMAGE>
