Abstract: 240,931. Petters, Ltd., and Bruce, R. A. July 12, 1924. Pneumatic springs; fluid-friction vibration-dampers.-A telescopic strut for aircraft of the kind comprising cylinder and piston elements adapted during telescoping to compress air within the cylinder and also to encounter obstruction provided by liquid flowing through a restricted orifice comprises, in combination, mutually rigid coaxial air and liquid cylinders separated by a fixed perforated partition, a piston connected to a piston-rod which passes through the perforated piston and serves to vary the effective area of the orifice, and sealing means upon both the piston and the liquid cylinder so arranged as, at all times, to be submerged in the liquid. In the form shown in the Figure, the piston d is provided with a pistonrod the extension e of which is tapered and passes through a perforated partition c dividing the cylinder into two parts a, b. The piston-rod is provided with a guide piston f. On telescoping of the parts, the orifice in the partition c is gradually reduced, thus causing increasing resistance to the flow of liquid, and the air in the cylindrical part a is compressed. A short spring n is provided to absorb some of the shock in the event of total or partial loss of air pressure. In a modification, the guide piston f is omitted and replaced by an enlarged head on the extension e which thus forms a ram, and the extension e instead of being tapered is provided with tapered grooves or flats to vary the effective area of the orifice.

Title: Selective calling arrangment
IPC: H04W88/02
Filed: 1976-04-28
Abstract: 1524125 Selective signalling AUTOPHON AG 28 April 1976 [28 April 1975] 17327/76 Heading G4H A portable receiver in a selective calling system wherein the calling signal comprises RF pulses of uniform width separated by first and second intervals respectively representative of the two binary states in the calling signal, comprises an RF demodulator 1 for generating D.C. pulses corresponding to the RF pulses, a differentiator 11 for producing a pulse in response to a leading edge of such a D.C. pulse, and a non-retriggerable monostable 13 triggered by a pulse from differentiator 11 to produce a pulse of width equal to said uniform width, signal recovery in the receiver depending exclusively upon monostable 13. Each trailing edge from monostable 13 is detected by differentiator 22 to increment a counter 2 and trigger a retriggerable monostable 23 of period between first and second intervals (to detect the bit values). Counter 2 enables its outputs in turn to scan a diode matrix 3 to provide the receiver address serial-by-bit to an EXCL-OR 15 for comparison with the output of monostable 23. An AND 14 detects the conjunction of inequality at 15 and the leading edge of a pulse from monostable 13 (via a differentiator 21) to reset counter 2. If the counter 2 is permitted to count to completion, and the last bits are equal, an AND 24 triggers a non-retriggerable monostable 43 to give an alarm at 5 for the duration of its period. Counter 2 is disabled if a retriggerable monostable 33, triggered from differentiator 21 and with a period exceeding the longer of the first and second intervals, times out. Counters can be used in place of the monostables. The functions of monostables 33 and 43 could be combined.

Title: Improvements in or relating to systems for sequentially addressing memory locations
IPC: G06F9/26
Filed: 1960-05-17
Abstract: 927,405. Electrical digital-data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 17, 1960 [June 4, 1959], No. 17418/60. Class 106 (1). In a magnetic core matrix means are provided for addressing a predetermined sequence of storage locations. Selection of an address is by half-drive currents on X- and Y-co-ordinate lines. Separate but similar apparatus is used for providing the sequence of each co-ordinate. An X-co-ordinate is stored and is used in the read-out and read-in of an address of the core matrix, but the read-in signal is applied to the co-ordinate store in order to set a magnetic core representing the next co-ordinate of the sequence. Suppose that the core matrix is 32 x 32 and that the sequence of X-co-ordinates begins with 0. Core 0 of the co-ordinate storage device of Fig. 4 is initially set by a pulse on a start line and a reset pulse is then applied on line 67 to all cores. An output then appears on sense lines 69 and 58 to set triggers X0 and 0X (Fig. 5) respectively. The triggers set by signals from the horizontal sense lines have only one output connected to AND gates in the core drivers, e.g. 77 of the co-ordinate selection matrix of Fig. 2; the triggers set by the vertical sense lines have two outputs applied one to each AND gate of an associated core driver 73 to 76. Coincident pulses are then applied to the lines " read gate " and " read bias gate." The read gate pulse is sufficient to set a core and is applied to that row of the selection matrix associated with the set trigger 0X; the read bias gate pulse is a full reset pulse and is applied to the columns of cores associated with the unset triggers X1 to X3. The result is that the core SW 0  is set producing a half-read pulse on the line 0. A " write gate " full reset pulse is then applied to the column of cores associated with the set trigger X0 causing the core SW 0  to be reset and a half-write pulse to appear on line 0. After passing through the core store 50 (Fig. 3a) the pulses on the selected co-ordinate line are applied to a terminal board which is wired so that, for example, as shown, the 0 input terminal is connected to the 1 output terminal. The output terminals are connected to the lines A0 to A31 which are the windings on the correspondingly numbered cores of the co-ordinate storage device. The core in the selection matrix provides when switched only a half-drive pulse to the cores of the co-ordinate storage device and the other half-drive pulse is supplied on the set line 66 (Fig. 4) simultaneously with the resetting, by the write gate pulse, of the set core, e.g. SW 0  of the co-ordinate selection matrix. As shown in Fig. 3a the sequence of addresses selected is (0, 0), (1, 1), (2, 2) . . . but other sequences may be followed by differently wiring the terminal boards. Apparatus is described utilizing two co-ordinate stores which can program more complicated sequences (Fig. 7, not shown).

Title: A new or improved method of, and apparatus for, the production of brewers' wort
Inventor: DUMMETT GEORGE ANTHONY
IPC: C12C7/20
Filed: 1960-05-18
Abstract: <PICT:0953445/C3/1> The concentration of essential hop oils in hopped brewers' wort is controlled by passing all or part of the wort to a stripping column, passing vapour and stripped oils to a fractionating device, and collecting and returning a regulated quantity of the stripped oils to the hopped wort.  A flow of wort in a pipe 1 is divided into a by-pass flow 3 and a flow 2 which enters a column 4 at an intermediate point and flows downwardly counter-flow to an upward vapour stream from a live steam supply line 5 which strips the wort and entrains the oils and passes to the upper part of the column 4 where fractionation occurs, vapour issuing into a line 7 connected to a condenser 8 which in turn connects with lines 10, 11 leading, respectively, to the top of the column 4 and to the by-pass line 3 (which has already picked up stripped wort through a connecting line 6).  The condenser also connects with an oils withdrawal line 12, lines 10, 11, 12 all being preferably valve-controlled.  Stripped wort from the foot of the column 4 may also be led by a line 13 to a boiler 14 which provides vapour to supplement or replace the live steam supply.
