Patent GB-2035440-A (GB)
Title: Draw-string fastener
IPC: A41F1/00
Filed: 1979-10-25
Abstract: A draw-string fastener comprising two sleeves (10, 12) having laterally extending protrusions (22, 24) which can be fitted into corresponding sockets (36, 34) in the walls of the sleeves. The length of the protrusions (22, 24) is such that the ends of the protrusions engage draw-strings threaded through the two sleeves when the two members have been firmly pushed together. In a second embodiment of the invention, the peg-like protrusions (22, 24) are replaced by hammer- head section protrusions (46, 48) which can be slid from opposite ends into the openings in the opposite ends of the two sleeve-like members threaded on the two draw-string ends. The isthmus of each hammerhead section protrusion is received in a slot which replaces the socket of the first embodiment and a firm grip on the string ends threaded through the two members is obtained by providing a ramp surface either on the end face of each hammerhead section protrusion or on the face of the string-receiving passage opposite to the slot and which is juxtaposed with the hammerhead protrusion when the latter has been introduced into the member. <IMAGE>

Patent GB-2071539-A (GB)
Title: Method of Swaging Tubes and Pipes Using Corrugation Techniques
IPC: B21D15/02
Filed: 1980-01-25
Abstract: The method alters the external dimensions of the cross-section of a tube for a short distance along from the end, such that the end is modified to form a new cross-section of reproduceable shape and dimension. The cross-section remains substantially the same except for dimensions but will differ from normal swaging by the fact that the extra material or unwanted material has been displaced by the formation of corrugations or folds thus allowing the reduction in dimension to take place. To avoid high stresses especially at corners rollers are used. The avoidance of 'scuffing' allows this method to be ideally suited for the reduction of pre-coated tube and pipe of non-round section to be swaged. <IMAGE>

Title: Electrostatic spraying
IPC: B05B5/043
Filed: 1981-03-04
Abstract: Apparatus for crop-spraying includes a rotor 18 over which the liquid is distributed to produce a mechanically atomised spray and a charging electrode close to the edge of the rotor which causes the liquid to be charged by induction. A positive electrode 32 produces a negatively charged spray and the resulting problem of condensation is inherent in inductive systems. An additional pair of negative electrodes 52, 60 is arranged above the rotor, with respect to the ground, to provide co-operatively a local field which repels spray from the charging electrode and also a field to ground which controls deposition. The absolute and relative potentials of the negative electrodes can be continuously varied with wind speed so that, while maintaining the local field effectively constant, the field to ground has an instantaneous value appropriate to maintain the desired deposition pattern. <IMAGE>

Title: Electrical snap switches
IPC: H01H3/00
Filed: 1981-04-07
Abstract: An electrical snap switch has a housing 1, 2 with a stationary contact 8 and a pivotally movable contact member 12 which engages the contact 8 in the closed position of the switch. The switch also comprises a slidable operating member 10 which, during opening of the switch, moves the line of action of biasing spring 13 to cause the contact member 12 to move with a snap action away from the contact 8. In the abnormal event of the contact member 12 becoming welded to the contact 8, or the spring 13 failing, opening of the switch is ensured by the contact member 12 being forced away from the contact 8 by the advancing operating member 10 which during opening of the switch moves in the same general direction as the direction of separation of the contact member 12 away from the contact 8. The contact member 12 may bridge one pair of stationary contacts 8 in one position and another pair of stationary contacts 9 in the other position. <IMAGE>

Patent GB-2083930-A (GB)
Title: Circuit for sorting a set of values into ascending or descending order of magnitude
IPC: G06T15/40
Filed: 1980-01-25
Abstract: The circuit comprises n-1 cells for sorting n values, each cell comprising as many bits as there are bits in the largest value to be sorted. During sorting the first of a set of values to be sorted is entered into latches 302, 303 of a cell a and a 1 is entered into a latch 304. The presence of the 1 causes the value in the latches 302, 303 to be transferred to latches 300, 301 and the previous value from a previous set in the latches 300, 301 to be transferred to the latches 308, 309 of a cell b. In the next clock period a new value is entered into the latches 302, 303 and the value in the latch 304 is 0. The presence of the 0 causes the new value in the latches 302, 303 to be transferred to the latches 300, 301 if it is greater than the preceding value as determined by comparison elements 306, 307, the preceding value being passed to the latches 308, 309, but causes the new value in the latches 302, 303 to be transferred to the latches 308, 309 if it is less than the value in the latches 300, 301. In this way the values will be sorted into descending order of magnitude and will sweep the values of the previous set before them as they pass through the circuit. A respective comparison element such as 306, 307 is provided for comparing each bit of the two values, and the arrangement is such that the most significant bits of the two values are compared first and, where the two bits compared are equal, a carry signal is supplied to initiate comparison of the next most significant bits of the two values. <IMAGE>
