Abstract: 1,231,286. Insulating building material of blistered clay nodules. DANSK LECABETON A.S. 12 July, 1968, No. 33291/68. Heading B5A. Insulating building material is made from clay or clay slate by heating the clay to above 1000‹ C. to convert it into incandescent, tacky, blistered nodules which under the pressure of the rollers of a rolling system are fused together to form a cohesive air-filled strip which is then further heated to a higher temperature and then cooled. The clay is heated in a rotary kiln 3 and the nodules of blistered clay 4 drop on to a sectionalized endless conveyer 7, the individual sections of which have lateral walls 8. The thickness of the layer of nodules is controlled by blade 11. The layer of nodules is compacted between rollers 12 and 10 to form a cohesive strip which is carried by the conveyer 7 into a heating chamber 14 having electrical heating elements 17. Reinforcing rods 18 coiled on roller 19 can be introduced into the strip from the rear. The strip then passes between a pair of horizontal rollers 21, a pair of vertical rollers 22, profiled to form a tongue and groove on the strip, and another pair of horizontal rollers 23. The strip then enters a cooling chamber 24. In the embodiment of Fig. 2 (not shown) the heating chamber is heated by oil burners to a temperature 50-100‹ C. above that of the rotary kiln and the strip is thus given a hard glazed finish. It may also be given extra electrical heating at the first part of the chamber 24 so that it is all at the same temperature before cooling begins.

A storing winch for handling a fluid supply cable formed by successive sections connected end to end comprises two hydraulically-driven drums 11, 13 either of which may be coupled to a central idler and storage drum 12 for rotation therewith, one driving drum winding on a section of cable while the other driving drum is paying out a previously wound section. The fixed axle 1 of all these drums is bored to supply fluid from a line 6 through stop valves 4, 5, swivel couplings 19, 20, and connections 23, 24 to any cable sections wound on the drums, the axle bore being divided by a wall 25. In drilling operations, when the connected sections of cable are to be fed down a well by a traction device (28), Fig. 2A (not shown), drums 11 and 12 are coupled by latches 14a and a cable section is wound thereon and is coupled to the connector 23 and valve 4 is opened. The traction device unwinds the cable while the motor of the drum 11 acts as a brake and when the cable is free of the drum 12, the latter is coupled to the drum 13 and a further cable section is wound thereon. When the original cable is fully wound off the drum 11 it is coupled to the new section on the drums 12, 13, the valves 4, 5, drum motors, and traction device being operated appropriately. The traction device comprises one or several endless chains provided with shoes which grip the cable, which may be an electric power cable.

Abstract: 1,239,536. Data processing systems. INTERNATIONAL BUSINESS MACHINES CORP. 18 March, 1970 [28 March, 1969], No. 12987/70. Heading G4A. Data processing apparatus prefetches instructions into a buffer, there being means responsive to decoding of a branch on condition instruction on which the condition data is not yet available to compare the addresses of subsequently fetched instructions with the address of the target instruction and to render such instructions cancellable until a compare equal is detected. An I box prefetches instructions from main storage into a multi-instruction buffer from which they are routed to a fixed point or a floating point execution unit. The floating point unit has an op stack for the instructions, operand buffers fed from main storage, execution circuitry and floating-point registers, the results going to the latter or main storage. The fixed point unit is similar except that the floating-point registers are replaced by general-purpose registers some of which supply base and index information to the I box for address modification. When the I box detects a branch on condition instruction, on which the condition data is not available, it prefetches a few instructions along the branch path into alternate buffers, and then prefetches along the no-branch path, the latter instructions being routed to the execution units with tags to prevent execution unless and until the branch condition is shown to be not met. The addresses of these instructions are compared with that of the target instruction (i.e. that to be branched to if the condition is met) saved in a register, and if equality is detected, tagging is discontinued. Equality means the target instruction (which is the first instruction of the branch path) has been reached along the no-branch path. If the branch condition is satisfied, the tagged instructions are not executed. The disclosure is described as a modification of that in Specification 1,130,270.

Abstract: 1,239,714. Time-division-multiplex switching systems. INTERNATIONAL STANDARD ELECTRIC CORP. 11 Feb., 1970 [20 Feb., 1969], No. 6630/70. Heading H4K. A group of subscribers TLN has access to the channels of a time-division-multiplex highway ML by way of a tdm concentrator TKF, connections between the concentrator and the highway being by way of the space divided channels KL each of which has a low-pass filter TP1 with a sharp cut-off, the sampling frequency f2 employed for the concentrator being at least half as high again as the sampling frequency f1 employed on the highway ML so that low-pass filters TP2. in the line circuits can be cheaply realized as the interfering side-bands are well spaced from the speech band. The filters TP2 can be comprised of RC-circuits or be constituted by the unmodified transmission characteristics of the line circuits themselves. The highway ML is multiplexed at the normal 8 kHz with a pulse amplitude to pulse code modulation converter MW sampling the 32 audio-links KL. The concentrator TKF may comprise a single highway operating at a sampling rate 4 times f1 or may comprise four highways each sampling at the rate f1 so that each audio-link KL is sampled at 4 times the rate f1 of highway ML. If only a fraction of the channels of highway ML are in use the scanning frequency in TKF may be 8 times f1.

Abstract: 1296596 Measuring force electrically J P CORBETT 23 June 1970 30486/70 Heading G1N [Also in Division G4] Force measuring apparatus includes a piezoelectric resonator 12 (Fig. 1) alternately stressed by an unknown force F so that it resonates at a first frequency and then relieved of stress so that it resonates at a second frequency, the difference between the first and second frequency being in indication of the applied force. Whenever solenoid 24 is energized armature 26 is moved to remove the support for arm 18 so that the force F is applied via arm 18 to quartz crystal 12, the force being removed when the solenoid is de-energized. The point of application of the force is adjustable by movement of a lead screw 54. To prevent the crystal being damaged by the application of an excessive force the crystal is mounted on a platform 16 forced upwards by a spring 60, the force being the limiting force to which the crystal is to be subjected. The energization and de-energization of the solenoid 24 is controlled by the output A of a counter 720 (Fig. 4) operating as a frequency divider. The output of the crystal 12 is applied to an oscillator 70, the output pulses from which are applied to a binary coded decimal counter 761 (with an overflow binary counter 762) for positive accumulation when the solenoid is energized and negative accumulation when it is de-energized, the difference count being displayed. The crystal may alternatively be made of Rochelle salt or tourmaline. The solenoid may be replaced by a piezo-ceramic or magnetostrictive element which when energized expands to lift the force transmitting arm from the crystal Fig. 6 (not shown). The accuracy of the apparatus may be improved by thermostatically controlling the crystal temperature. The apparatus may be used for measuring pressure, weight or as an integrating accelerometer. If a flexible diaphragm bellows in the side of a pressure vessel is used to apply the force, the apparatus may be used as an altimeter or includes depth measuring instrument.

Abstract: 1314831 Recirculating flushing systems of chemical closets M HILLER 19 April [9 March 1970] 11257/70 Heading E1C A recirculating flushing system of a chemical toilet comprises a sealed reservoir which is separate from the container into which the pan discharges, a pivoted flap for sealing off the outlet from the pan into the container, a pump for delivering flushing liquid from the reservoir to the pan to flush the same, and a conduit arrangement leading from the bottom of the pan to the reservoir and incorporating a narrow bore tube or a filtering aperture to prevent solid waste material from being recirculated. In one embodiment, Fig. 2, the conduit arrangement comprises a tubular member 15 having a filtering aperture 16 at one end communicating with the bottom of the pan 10 via a valve plate 21 movable between open and closed positions by rotation of a knob 27a which causes a cam 33 to operate a spring- loaded rod 23 to which the valve plate is secured, the other end of member 15 having a branch 15b leading to the reservoir 13 and a closed end 15d through which the rod 23 passes in sealed manner. A pump 19, which withdraws liquid from the reservoir 13 via pipe 18 and feed it to a flushing ring (not shown) on the pan, is mounted on the reservoir and controlled by an electric switch 29 which is operated by depressing the knob 27a. In operation, a pivoted flap (not shown) is moved to close the bottom of the pan during use of the toilet, after which the valve plate 21 is moved to open position and the pump 19 operated, by simultaneous rotation and depression of the knob 27a. After the walls of the pan have been adequately flushed, the knob 27a is released to switch off the pump and re-close the valve plate 21, after which the pivoted flap is opened to release the solid matter into a container (not shown) below the pan. In a second embodiment, Fig. 4, the conduit arrangement comprises a narrow bore pipe 126 leading from a perforated ring pipe arranged within a rubber or like seal 117 forming part of a pivoted flap adapted to close the bottom of the pan, a pump 129 being operated to recirculate flushing liquid via the pipe 126, sealed reservoir 123, pipe 129 and jet nozzle 127, when the flap is closed. Operation is otherwise similar to that of the first embodiment. Reference has been directed by the Comptroller to Specification 1,171,884.
