Granted: 1971-03-29
Abstract: Composite filter fabric for filter press.. G6B. Comprises a thick supporting layer providing the mechanical strength and a superimposed thin layer of fabric with the desired filtration properties, the layers being bonded together so that superimposed but unbonded regions exist. In particular, the two layers may be joined together round the edges and round a central aperture, or along radial lines, by heat sealing, adhesive or by stitching. The composite fabric overcomes the difficulties of compaction and/or plugging up of the filter cloth where a single layer of thickness adequate to provide the necessary mechanical strength is used.

Abstract: Material is passed between radiation source and detector. Latter produces pulses, the mean recurrence rate of which is a function of the radiation received. Pulses are counted during measuring time periods in which the material is in the radiation path and during standardising periods, in which no material is in the path. The two counts are dependent on 1 error-producing factor. Operation of the counting means during the measuring periods is modified according to the count in the preceeding standardising period, thus providing a measure with compensation for the error-producing factor. Also applicable to measuring thickness with constant density or vice versa.

Abstract: 1,050,356. Gas filter. CAMBRIDGE FILTER MANUFACTURING CORPORATION. Feb. 27, 1964 [Feb. 28, 1963], No. 8226/64. Heading BIT. [Also in Divisions Dl and D2] A pleated filter for removing solid and liquid particles from gases has its pleats supported in spaced relation by spacers having corrugations which transform across the spacer from large corrugations along one edge to a greater number of small corrugations along an opposite edge. Thus the filtering surfaces are set at angles to one another and provide therebetween gas flow passages which increase in cross section in proportion with the increased gas flow at any given point in the flow both up-and downstream of the filter material. It is preferred that each large corrugation should transfer to an odd number of smaller corrugations. The separators are made of cardboard, plastics, sheet aluminium or the like. The filter paper is folded as shown and separators 40, inserted to provide tapering passages. Gas to be filtered enters on both sides of the separators between the filter paper at the sections having large corrugations adjacent the gas inlet, and passes through the filter paper to leave the filter through the large corrugation sections at the outlet end. An apparatus is described for producing the separators, either from continuous strip or single blank material, utilizing a pair of contrarotating synchronised rollers having axially arranged blades of tapering projection from the rolls, to form the corrugations.

Abstract: 1,051,663. Pulse modulator. STANDARD TELEPHONES & CABLES Ltd. Feb. 20, 1964 [Feb. 27, 1963], No. 7899/63. Heading H3R. In an amplitude, frequency or phase modulator in which the carrier signal is modulated by a square wave pulse train, e.g. a telegraph signal, means are provided for adjusting the rise time of the modulated carrier wave pulses. In the frequency modulator shown in Fig. 1, the square wave signal is applied via terminals 3, 4 to a pulse shaper circuit comprising resistor 1 and capacitor 2 to provide a signal of the form shown in Fig. 2B. This signal is applied via an amplitude control 5 to the base of a transistor 9 which is adjustable biased by potentiometer 7 and the transistor output signal is applied to a second transistor 13 which includes a diode 19 in its emitter circuit. During positive excursions of the signal at the base of transistor 13 the diode is cut off and produces no effect on capacitor 23 which is one of the frequency determining components of carrier oscillator 25. During negative excursions the diode is driven to saturation and in consequence its low impedance effectively connects capacitor 21 in parallel with capacitor 23 and alters the carrier frequency. The rise time of the carrier signal pulsed is controlled by the amplitude of the signal applied to transistor 13 which is determined by the setting of potentiometer 5 and where the input signal has equal mark to space ratio the modulated signal is adjusted for a similar ratio by potentiometer 7. Fig. 3 (not shown) shows application of the invention to an amplitude modulator.

Abstract: 1,052,799. Supplying liquid fuel to burners. M. CECCARELLI. March 12, 1964, No. 10443/64. Heading F4T. [Also in Division F1] An apparatus for feeding liquid fuel -intermittently to kilns for ceramic ware comprises a double piston 5, 6 arranged in coaxial cylinders 1, 2 and a further double-piston 7, 8 arranged in coaxial cylinders 3, 4. Liquid fuel is delivered under pressure by a pipe 9 to the underside of the piston 5 and through apertures 10b and 12b in the cylinder 4 and through a pipe 12 to the upper side of the piston 6. The latter has a greater area than the piston 5 and consequently the double piston 5, 6 moves downwardly. When the double piston reaches its bottom position fuel passes through an axial hole 21 and a radial hole 22 in the double piston 5, 6 into an annular groove in the top piston 6 and thence by a pipe 16 to the space above the piston 7. The double piston 7, 8 therefore moves downwardly and fuel sucked into the space 14 below piston 8 during the previous upward stroke of the piston 7, 8 is now fed through a check valve 19 and a regulating valve 20 to a nozzle 18 in the kiln. At the same time fuel under the top piston 7 flows through a pipe 23 and the space above the lower piston 5 to a fuel-return pipe 10. When the double piston 7, 8 reaches its lowest position the fuel above the upper piston 6 flows through the pipe 12 and the space above the piston 8 to the return pipe 10. The double piston 5, 6 therefore moves upwardly to its start position and in this position fuel flows along the pipe 23 to the underside of the piston 7. The double piston 7, 8 therefore rises, the fuel above the piston 7 flowing to the return pipe 10 along a pipe 16 and fuel being sucked from the return pipe 10 through a check valve 15 into the space 14 below the piston 8. When the double piston 7, 8 reaches its upper position fuel again flows through the pipe 12 to the cylinder 2 and the cycle repeats. The number of fuel injections in unit time is controlled by a valve 11 in the pipe 12.

Abstract: 1,226,978. Screwing-up and unscrewing nuts, &c. DESOUTTER BROS. Ltd. 12 Sept., 1969 [29 Nov., 1968], No. 56653/68. Addition to 1,180,771. Heading B3N. In a power-operated impact wrench or screwdriver having in accordance with the main patent an inertia cylinder 141 coupled to rotary hammers 150 by resilient means which constrain the inertia cylinder from moving relative to the hammers until the impact delivered to an anvil 151 reaches a predetermined value whereupon the inertia cylinder moves in relation to the hammers and acts to increase the amount of cyclic disengagement of the hammer from the anvil thereby operating control means for interrupting the supply of power to the tool, the resilient means is in the form of a pair of spring levers 149 each of which is integral with a hammer 150 and supported in a bore 148 in the inertia cylinder 141. A spring 143 and balls 140 which are disposed in inclined grooves 139 in a drive spindle 137 reciprocate the inertia cylinder 141 to engage and disengage the hammers 150 and anvil 151 as the spindle and the inertia cylinder are driven by a vane type air motor 125 through planetary gearing 138. The spring levers 149 project from the bores 148 into eccentric counter bores 152 which accommodate flexing of the levers. A waisted portion 153 of each spring lever 149 provides a different bonding resistance in different radial directions so that the levers 149 may be rotated about their longitudinal axes to adjust the maximum torque delivered by the tool. For this purpose each spring lever 149 has splines 154 which are disengageable from splines in the bore 148 by turning a cover plate 155 to expose a hole 156 and then inserting a tool to depress the lever against the action of a spring 157. Each spring lever 149 can thus be turned and then released to occupy a new position. In operation, the spring levers 149 remain in contact with one side of the counter bores 152 so that the inertia cylinder 141 and the hammers 150 move in unison until the resistance to movement of the anvil 151 under the impact of the hammers reaches the predetermined value whereupon the cylinder 141 continues to move when the hammers strike the anvil and the levers 149 are flexed. Subsequent rebound of the inertia cylinder 141 increases the disengaging movement of the hammers from the anvil so that the cylinder 141 strikes a trigger 134 which unseats a ballvalve 130 to allow closure of a spring-loaded piston valve 120 for cutting off the air supply to the motor 125. The piston valve 120 remains in the closed position until the air supply is terminated by release of a push-button valve 110 which is initially depressed to cause clockwise rotation of the motor. A second push-button valve 111 provides for anti-clockwise rotation but as described the torque control operates only during clockwise rotation. In other embodiments the maximum torque delivered by the tool is adjusted not be varying the stiffness of the spring levers but by variably pre-stressing them.

Pulses from gate 14 pass through one of two gates 15, 16, which are opened alternately every group of n 1 .n 2  pulses by a bi-stable 24, to pass to a corresponding counter 17, 19, the contents of each being printed 25 whilst the other is counting. As applied to measuring the average speed of a vehicle over a predetermined distance, each pulse represents an equal increment of travel of the vehicle, and the sub-groups of pulses, which approximate to measures of instantaneous speeds of the vehicle, are uniformly distributed with respect to distance. The system is also said to be of use in measuring the sideway force co-efficient for a vehicle.
