Title: Improvements relating to apparatus for the manufacture of gas
IPC: C10J3/72
Filed: 1943-01-07
Abstract: 560,584. Gas manufacture; fluidactuated valves. HUMPHREYS & GLASGOW, Ltd., and COHEN, H. T. Jan. 7, 1943, Nos. 322 and 3325. [Class 55 (ii)] [Also in Group XXIX] In gas making plant in which coal gas is drawn from retorts b, and water gas from a generating plant a by an exhauster c, a gas holder f of substantially smaller size than the normal relief holder is provided, and the connection g<1> between the holder and the exhauster inlet is gradually opened by a valve such as h by the rising of the bell of the holder, and gradually closed by its fall, so that sudden fluctuations in the flow of water gas to the exhauster are prevented. The gas from the exhauster passes through purifiers d and is stored in a holder e. The valve h is operated by a link jand lever i attached to the holder bell. A valve k, similarly actuated, positively shuts off the exhauster from the holder to prevent the holder from being subjected to suction. In one modification, Fig. 2, a tapering member h suspended from an adjusting screw z extends into the outlet pipe g<1> which is throttled by an amount dependent on the position of the bell. A dip pipe l seals off the outlet pipe when the holder is nearly empty. In another modification, Fig. 3, a butterfly valve h is opened by a rod j when the holder bell rises, to permit a greater flow of gas through pipe g<1>, and closes when the gas supply from pipe g and the holder drops. The valve position is set by a weight h3 adjustably secured to a cranked arm h<2>.

Title: Improvements in or relating to transistor circuit arrangements
IPC: H03B5/12
Filed: 1959-01-05
Abstract: 902,820. Transistor switching and oscillator circuits; amplitude modulation systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 5, 1959 [Jan. 8, 1958], No. 373/59. Classes 40 (5) and 40 (6). A current is supplied from a first transistor to the emitter of a second transistor, the current flowing substantially wholly to the collector or base of the second transistor 2 depending on the relative potential of these two electrodes. The Figure shows a first transistor 1 connected to a stabilizing resistor 3 and arranged as a high impedance supply for a second transistor 2. The collector circuit of the latter transistor includes a coil 9 coupled regeneratively to a tuned circuit 5 in the base circuit of transistor 1 to cause the circuit to oscillate. If the potential of the base of transistor 2 exceeds that at the collector the current is diverted to the base circuit and provides negative feed-back to the tuned circuit through coil 7 so that the oscillation amplitude is limited. Modulation may be effected by modulating the voltage of the supply 10 or the bias voltage applied to terminals 8.
Patent GB-873164-A (GB)
Title: Improvements in or relating to information storage devices employing magnetic cores
Inventor: QUARTLY CHARLES JOHN
IPC: H04H20/88
Filed: 1960-01-06
Abstract: 873,164. Circuits employing bi-stable magnetic elements. MULLARD Ltd. Jan. 6, 1960, No. 488/60. Class 40 (9). Pairs of cores each store a bit and its complement and are arranged in two groups served by a common drive winding which may also be used as an output winding, each pair being served by an individual read and write wire or by separate wires for these purposes, an output amplifier being fed by the outputs from each group such that energization of the common drive winding produces outputs in opposition from each group. As shown in Fig. 4, a row of core pairs is divided into groups A and B each containing an equal number of cores. The groups are driven in parallel by half-write pulses of one polarity or the other from sources G1, G2 in coincidence with a half-write pulse in the read/write wire of a selected core pair. Since each core pair has the same impedance to the drive wire regardless of its state the return currents, over equal resistors R1, R2 balance and provide substantially no input to an output amplifier connected across them. On read-out only one core pair produces output and the amplifier input circuit is unbalanced. If a separate output wire is used, as shown in Fig. 7, the drive from generators G1, G2 may be applied serially to the groups A and B and the output wire may be wound in opposite sense in one group compared with the other so that voltages induced by drive from G1, G2 cancel out. The positions of amplifier and generators may be interchanged. Each row of core pairs may form the row of a matrix, columns of which have a read/write wire in common. Simultaneous drive from generators G1, G2 of all rows and a half-write pulse on a selected column registers a word in that column. A read-out pulse applied to the column will energize the row amplifiers. A more detailed arrangement of the circuit of Fig. 4 is shown in Fig. 5. A pulse source G over a switch t1 t2 switches on transistor T1 or T2 according to the polarity of the pulse needed and the group A or B involved. The output across resistors R1, R2 is fed to two push-pull transistor stages which for output of one polarity switches transistor 17 on and for the opposite output switches transistor T8 on, thus providing a positive indication of both 0 and 1 states. The core pairs may be provided as apertures in a plate of magnetic material.

Title: Improvements in or relating to cooling systems
Inventor: WINDEBANK ROBERT WILLIAM
IPC: F25D31/00
Filed: 1956-01-07
Abstract: 859,768. Cooling systems; cooling liquids by direct contact, with cold solids; temperature - responsive actuating elements. PLANER Ltd., G. V. April 5, 1957 [Jan. 7, 1956], No. 623/56. Classes 64(1), 64(2) and 64(3) [Also in Group XXIX] A chamber, zone or object is cooled to a predetermined sub-atmospheric temperature by a circulating coolant liquid such as methylated spirit or silicone oil which on leaving the chamber, zone or object passes through a thermostatic valve 23 sensitive to the temperature of the coolant and which directs the latter either through a separate cooling medium of a different character from that of the coolant liquid, or through a flow path which by-passes the separate cooling medium. In the form shown, the coolant liquid flows through a coil 19 to cool a chamber 20 and then passes through a duct 21 to the valve 23.- The valve directs the coolant according to its temperature either through a pipe 24 to a chamber 11 in which it is cooled by direct contact with a medium such as dry ice, or through a pipe 26 to an electric heating means 30 or through a by-pass 25 direct to the sump 15 from which the coolant at the predetermined temperature is pumped by the pump 16 through a conduit 18 to coil 19 surrounding the chamber 20 to be cooled. The required coolant temperature is preset by means of a knob 38 on the valve 23 which thereafter acts to maintain the temperature appropriate to the setting suitably by directing the coolant before it reaches the sump 15. Temperature responsive actuating elements. The valve plate 44 rotation of which directs the coolant to one or other of the pipes 24, 25 or 26 is rotated either directly or through a servo mechanism by means of a thermally sensitive element comprising two oppositely-coiled spiral bimetal elements 40, 42 interconnected by a bar 41. The inner end of the spiral element 40 is connected to a spindle 37 terminating in a control knob 38 having an index co-operating with graduated temperature scale 39. Means such as friction discs are provided for retaining the spindle in its adjusted position against the force exerted by the bi-metalelements 40, 42. The inner end of the other spiral element 42 is joined by a spindle 43 to the valve plate 44, which although shown spaced therefrom, is normally arranged to rotate with its undersurface in sealing engagement with the stationary valve seating 46. According to the angular position of the valve plate 44 liquid coolant entering the valve chamber 35 through a pipe 21 and flowing through the port 45 in the plate, is directed either through a port 47 leading to a by-pass pipe 25 through arcuate port 48 to a pipe 24, or through arcuate port 48 leading to a pipe 26.

Abstract: 1,187,361. Automatic temperature control systems. SHIPOWNERS REFRIGERATED CARGO RESEARCH ASSOCIATION. Dec.31, 1968 [Jan.4, 1968], No.682/68. Heading G3R. A refrigeration plant has a cooler 3 through which air is drawn by a fan 5 and passed through a first duct 7 into a container from which it is returned into a second duct 11, with a tube 15 connected between the first and second ducts, part of the tube being perforated and having a temperature sensitive element 19 of a thermostat arranged therein, and a valve 21 arranged in the tube between the temperature sensitive element and the end of the tube in the first duct, the valve controlling the flow of air through the tube between the first and second ducts and being arranged to close when the temperature of the air passing the temperature sensitive element reaches a determined low value and to open when the temperature of the air reaches a determined high value. The fan 5 is run continuously and in one mode of operation, e.g. for cooled cargo, the valve 21 is opened at the same time as cooler 3 is rendered operative under the control of a thermostat 17 which measures the temperature of the air leaving the fan 5. At a determined temperature the cooler is disconnected at the same time as valve 21 is closed, hence the thermostat measures the returned air temperature from the container. In another mode of operation, e.g. for frozen cargo, a switch 23 is opened, hence the valve 21 is continuously closed and the cooler 3 is operated according to returning air temperature. The apparatus may be arranged as a clip-on unit for a container, or it may be arranged as a permanent installation.  The thermostat may be of the bulb type and/or connected to a recorder. The electrical switch 23 may be replaced by a shut-off damper in the tube 15.
