IPC: B04C3/00

Abstract: 1,227128. Centrifugal separators. PORTATEST MFG. Ltd. 23 April, 1968 [24 April, 1967], No. 19067/68. Heading B2P. In a vertical centrifugal separator for separating liquid and gas, Fig. 1, a baffle 4 in the form of a flat solid disc mounted on a tubular support 17 is disposed between a separation chamber 2 and a liquid collection chamber 3. The downwardly spinning vortex of separated gas is prevented by the baffle from entering the chamber 3 and is discharged through a vortex finder 7 while separated liquid collected on the wall of the chamber 2 passes through the gap 18 into the chamber 3. The baffle may alternatively be dished, conical or skirted. The vortex finder is made of two parts interconnected by channel-shaped members 30 and having between them an annular gap 31 communicating with a suction chamber 27 which in turn communicates, via a conduit 19 and openings 21 and 20 in the tubular support 17 and the baffle 24 respectively, with the centre of the gas vortex so that any liquid particle entrained in the vortex finder is sucked out through the gap 31 with some of the gas and recirculated into the separation chamber. A skirted baffle 37 is provided on the vortex finder to prevent any liquid creeping down the vortex finder tube from entering the mouth 13 thereof. A splash disc 40 may, as shown, be disposed in the collection chamber 3 to stop the downward helical flow of separated liquid as it enters the chamber 3, the liquid flowing through openings 41, Fig. 3, in the disc so that any gas entrained in the liquid is concentrated at the top of the chamber 3 and finds its way back into chamber 2. Plates 44 depending from the disc 40 serve to isolate the newly admitted liquid creating a quiescent zone between them. A liquid level float mechanism may be threaded in an outlet 46 to regulate the liquid discharge through an outlet 8, the float being conveniently located in the quiescent zone between the plates 44. Relative dimensions of the different parts are given.

Abstract: 1,230,648. Data processing. GENERAL ELECTRIC CO. 11 July, 1968 [14 July, 1967], No. 33076/68. Heading G4A. A data processing system includes a multistage adder, register means for supplying information items to the adder, and control means indicative of the items supplied for selectively applying a signal to selected portions of the adder indicating absence of a carry to force the adder to achieve a stable state of operation in a shorter time period than that required for a carry signal to propagate from the least significant to the most significant stage of the adder. Adders and data transfer.-A parallel binary floating-point carry-propagate adder with separate exponent and mantissa sections can be fed selectively from a first register and/or either of two further registers and can feed its output to either of the further registers, so that besides addition the adder can be used in inter-register transfers. Inter alia, interchange of the contents of the two further registers is possible using the adder and another path between the two registers. Transfers may involve shift. During transfer only one register is gated to the adder inputs and when this happens zero carries are forced into stages 04, 10, 16, 22, 28, 34, 37 of the mantissa section of the adder (the mantissa stages being numbered 00-38) by extra circuitry and less time is allowed for the adder to settle before its output is utilized than would be the case if true carries could occur and time had to be allowed for propagation the full length of the mantissa section. During addition of the mantissa contents of the first register and of a particular one of the further registers, in another embodiment, other circuitry looks for equal bits from corresponding stages of the two registers in each of three areas, viz. mantissa stages 09-12, 19-22 and 29-32 respectively, since if the register inputs to a given adder stage are both 0 there can be no carry from that stage whatever the carry input from the next lower stage and if both register inputs are 1 there must be a carry from that stage. This circuitry controls a timing counter to reduce the time allowed for settling from 3 clock times to 2 where this can be done without error.

Abstract: 1,257,357. Control systems for stud welding apparatus. TRW Inc. 8 May, 1969 [8 May, 1968], No. 23432/69. Heading H2H. Stud-welding apparatus comprises means whereby the duration of a pilot arc can be extended so as to produce more efficient welding with certain materials and the control circuit for the welding operation comprises solid state elements. The pilot arc is extended by supplying the arc from a three-phase A.C. source whereas the welding arc is supplied from a single phase A.C. source. A welding operation 'is begun by placing a stud in a welding gun and positioning the stud on a workpiece. Operation of the gun trigger then causes a control circuit to be energized by way of a transistor, the energy source being rectified A.C. The control circuit comprises four subcircuits the first of which, when energized causes energization of the stud retracting coil and at the same time applies a three-phase voltage, by way of controlled rectifiers, to the stud and workpiece to strike a pilot arc which is extended by maintaining the gate potentials on the controlled rectifiers by means of a second and a third sub-circuit. The third control circuit also initiates the striking of the main welding arc and a fourth sub-circuit, which operates simultaneously with the third subcircuit, de-energizes the stud retracting coil whereupon the stud is plunged on to the workpiece by means of a spring. All the sub-circuits comprise unijunction transistors which are biased by capacitors so as to produce triggering signals for thyristors to provide the necessary switching operations.

In the control system of this application groups of utilization controls 330, Fig. 1, located at receiving positions of the entertainment system are connected to respective coders 320 arranged serially in a loop 312, 314, connected to a central column timer 310. Utilization circuits 332, such as service call lights and bells, are connected in groups to decoders, also arranged serially in a loop 316, 318, connected to the column timer 310. Timing signals fed from the timer round the two loops cause the utilization circuits to respond to the condition of the corresponding utilization control. The utilization controls and utilization circuits are each enabled sequentially by timing signals from the column timer 310 with all the controls or circuits connected to one coder or decoder being enabled before any control or circuit of any other coder or decoder. When all the controls or circuits connected to one coder or decoder have been enabled, timing signals are passed through that coder or decoder to the successive coders or decoders and the signals from the successive coders are returned through that coder to the column timer for onward transmission to the appropriate decoder, via the decoders whose operation on that cycle of operations has been completed. Preferably, the coders and decoders are enabled sequentially from one end of the loop during one cycle of operations and from the other end of the loop on the succeeding cycle. The last coder in the loop is arranged to emit a characteristic signal on completion of the cycle of operation, non- production of which causes operation of alarm circuits. At the end of each cycle of operation a synchronizing signal from the column timer resets all the coders and decoders so that the cycle can be repeated. A logic circuit for a coder is described with reference to Fig. 3 (not shown) and a logic circuit for a decoder, with reference to Fig. 4 (not shown):
