Title: Improvements in or relating to sleeping cars
IPC: B61D31/00
Filed: 1930-02-27
Abstract: 343,758. Railway sleeping- cars. SCHWEIZERISCHE WAGONS- & AUFZUGEFABRIK AKT.-GES. SCHLIERENZURICH, Schlieren, Zurich, Switzerland. Feb. 27, 1930, No. 6586. Convention date, Nov. 2,1929. [Class 103 (iv).] In a railway sleeping-car having end entrances the central portion between the bogies is depressed below the level of the end platforms 1, Fig. 4, so as to furnish at this part the necessary height for the provision on one side of a lower side corridor 4, Fig. 6, giving access to a series of lower sleeping compartments 5, and on the other side of an upper side corridor 15 giving access to sleeping compartments 16 located partly above the corridor 4 and partly above the lower sleeping compartments 5. Steps to and tu lead respectively from the end platforms to the upper and lower corridors, while there is a step down on entering the lower compartments 5 and a step up on entering the upper compartments 16, further stepped or raised portions of the floor being disposed at the outer sides of all these compartments for accommodating seats 7 adjacent to the berths 6. In order to maintain the full height of the corridor 4 at the ends of the car over the bogies, the lower sleeping compartments 5 are restricted to the central portion of the car and give place at the ends thereof to spaces 13 in which braking apparatus, batteries, and other accessories are accommodated. The partitions 12 between the dressing spaces of adjacent sleeping compartments are shaped as shown in Fig. 4 so that lavatories 9, 10 may be arranged close together, but one in each compartment, while flaps 12a in these partitions may be opened for speaking communication between the compartments. The partitions 22 between the berths 6 of adjacent compartments are formed with detachable upper portions which may be lowered when it is desired to convert two single-berth compartments into one double-berth compartment. Toilets 100 are located near each end' of the car with water reservoirs above them.

Title: Antennae with linear aperture
IPC: H01Q19/13
Filed: 1967-02-10
Abstract: 1386777 Aerials; radar THOMSON-CSF 10 Feb 1967 [22 Feb 1966] 6605/67 Headings H4A and H4D An antenna, particularly for use in airborne radar, has means for compensating at the reception, the phase variation ## = 2#(d/#)sin # due to motion of the craft between two successive pulses at O 1  and O 2 , less Fig 4 when the transmission of these pulses is coherent. This compensation is achieved by linearly displacing the phase centre of an antenna having a linear radiating aperture with respect to that position of the phase centre corresponding to a symmetrical illumination of the aperture, this displacement being performed by illuminating the aperture with a linear and variable dissymmetry. As shown in Figs. 2, 3 an antenna 1 of the pill box type has a two channel primary source 2 supplied by a wave guide 3, this source radiating towards a parabolic cylinder reflector 4 transmitting energy to a linear radiating aperture A, B. The source 2 is divided into two channels 21, 22 by a magic Tee 20, the channels comprising phase shifters 23, 24, e.g. varactors, whereby the phase shift between the channels may be varied electrically, the energy passing through the channels being radiated by mouths 25, 26. The phase shift between the two channels displaces the position of maximum illumination of the reflector 4 and thus creates dissymmetry in the illumination along the length of aperture A, B. A diagrammatic circuit embodying the antenna described with reference to Fig. 5 (not shown) has means for varying the displacement of the phase centre in accordance with the speed of the aircraft.

Title: Improvements in centrifugal electric switches
IPC: H01H29/26
Filed: 1946-03-04
Abstract: 608,994. Centrifugal switches; mercury and other conducting-liquid switches. LAMBERT, H. L. March 4, 1946, No. 6670. [Class 38 (v)] In a centrifugal-switch a tube 21 apertured at 24, extends into close proximity of the end 23 of a housing 8 forming a sealed-chamber 20, the housing being partly filled with a conducting-liquid 25, which preferably is mercury, and partly by an inert-gas. A body 26 having a density greater than that of the liquid 25 is slidable in the tube 21 and is normally supported by a spring 27. The switch is mounted between spring-arms 7 on a frame 3, 4, 5 radially adjustable on a disc 2, rotation of which confines the liquid and the body 26 to the end 23 of the housing. In the event of over-speed, however, the body 26 overcomes the spring 27, whereupon the liquid-level outside the tube 21 rises and bridges 'conductors 28, 29. In a modification, the liquid 25 may be non- conducting and the switch may be operated through a float.

Title: A lance for gas injection into a liquid metal bath
IPC: C21C5/46
Filed: 1959-02-26
Abstract: 902,122. Gas-injection lances. LICENTIA PATENT VERWALTUNGS-G.m.b.H. Feb. 26, 1959 [Feb. 26, 1958], No. 6696/58. Class 72. The depth of immersion of a gas-injection lance in a liquid metal bath is measured by the pressure of the gas flowing through it at a calibrated rate of flow, and the depth is adjusted to the required value whereby maximum oxidation is effected without injury to the furnace lining. The lance may be provided with a monometer and variable throttle, but preferably the lance 1, Fig. 2, is provided with an auxiliary tube 10 terminating above the liquid metal. A differential pressure ring balance 3 includes a throttle 4, and a second differential balance 7 determines the difference in pressure between points 8 and 9, which is a measure of the gas pressure at the outlet of the lance. Calibration is effected by a float 11 and arm fixed at a pivot 13, by which the angle of the lance feed tube is related to the depth of the nozzle h. The dimensions of the auxiliary tube is such that when both it and the lance are discharging into free atmosphere, no pressure difference exists, and the auxiliary tube section is large in relation to the flow of oxygen or other gas which may also flow over the surface of the well. In further modifications (not shown), a rotary furnace is provided with an oxygen-lance the predetermined immersion depth of which is automatically controlled to take account of variations in inclination of the axis of the rotary furnace and therefore also variations in depth of the melt. Oxygen feed pressure is controlled by coarse and fine adjustments governed by pneumatic means operated by the pressure of gases flowing out from the furnace. The oxygen lance is watercooled, and the temperature difference between inlet and outlet is controlled; warning devices operate when a pre-set range, e.g. 18‹ C. inlet, 40‹ C. outlet, is exceeded. In one example, flow of oxygen gas at 3.5 atmos. through the auxiliary tube is set at 10 c. metres per hour, and through the lance at 1000 c. metres per hour after balancing the pressures by control valves in each tube; the lance is then immersed at the desired level, and monitoring controls switched in to maintain pressure and immersion at the desired rates during the blowing period.

Title: Improvements in and relating to Candle Moulding and Packing Machines.
Inventor: DAY WILLIAM HARPER
IPC: C11C5/02
Filed: 1918-04-23
Abstract: 125,746. Day, W. H. April 23, 1918. Right to Patent relinquished. Candles.-In a machine for moulding and packing candles, the moulds and the holes in the candleclamps are arranged in groups corresponding to the number and arrangement of the candles in each packet, and the candles are delivered from the clamps to the packets through shoots, so as to be packed without handling. Fig. 4 shows the arrangement of the moulds. The clamps and shoots are carried on a frame which is pivoted so that, when the candles are being delivered to the clamps, the shoots are uppermost as shown in Fig. 3, and the whole can then be inverted so that the candles on being released from the clamps fall through the shoots 6 into the packets. The shoots 6 may be made in two portions connected by springs 11. The construction of clamps is shown in Figs. 5 and 6. The candles are delivered from the moulds into holes in two fixed boards, and are then held by moving two sliding boards 4, 5, as shown in Fig. 6. The holes in the sliding boards may be so arranged that, when the boards are returned to release the candles, the candles in the centre of the group fall a little before the others.

Title: Electrical digital computing engines
Inventor: NEWMAN EDWARD ARTHUR
IPC: G06F7/52
Filed: 1956-03-05
Abstract: 802,175. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 4, 1957 [March 5, 1956], No. 6904/56. Class 106 (1). An electrical binary digital computing engine has means for producing a first set of number signals representing a first number multiplied by different powers of two, means for producing a second set of number signals representing a second number also multiplied by different powers of two, means for selecting under the control of selecting signals a number signal from each set and means for producing a number signal representing the sum or difference of the numbers represented by the selected signals. As described for an engine adapted for multiplication, the multiplicand A in serial binary form is fed through three delays 4, 6, 8, Fig. 1, so that the outputs therefrom represent 2A, 4A, 8A. The multiplier of from 0 to 10 is staticized as four binary digits and an appropriate one of the lines X0 to X10 is energized thereby through the tree circuit 34. These lines are fed to appropriate ones of the " or " gates 24, 26, 28, 30, 32, so that combinations of A, 2A, 4A, 8A are selected to be added or subtracted in the adder-subtractor 2 thereby producing the required multiple of A as output. The output from the circuit of Fig. 2 is a number of the form A2<SP>m</SP>Œ B2<SP>n</SP>. The number A in serial binary form flows through the delays 4, 6, 8, and the number B also in serial binary form flows through the delays 5, 7, 9. The number m in staticized binary form sets up the tree 35 one output of which gates A, 2A, 4A or 8A to the terminal 22 of the adder-subtractor 2. Similarly the number n in staticized binary form sets up the tree 37, one output of which gates B, 2B, 4B or 8B to the terminal 20 of the adder-subtractor 2. A staticized digit at the terminal 18 determines whether the adder-subtracor 2 adds or subtracts. In the embodiment of Fig. 3 the number A in binary form flows through a series of unit delays 40, 42, 44, 46, 48, 50, 52 from which the outputs represent 2A, 4A, 8A, 16A, 32A, 64A, 128A. The outputs and the original number A are fed to two adder-subtractors 56, 58, 62 through a maze 54 comprising " or " and " and " gates controlled by a tree 60 set up by seven staticized digits to energize a particular one of the 128 output lines of the tree corresponding to any integral multiple by from 0 to 127. The adder-subtractors 56, 58, 62 each subtract or add the input at the terminal Œ from or to the input at the terminal + according as the terminal SUB is energized or not. To produce multiples by a larger number a serial accumulator 64 is fed with the output from the addersubtractor 62 and a desired product may be built up therein. The multiplier in this case may have its digits staticized in groups of seven at the tree 60 and the result of these partial multiplications is fed at suitable times to the accumulator 64. Specifications 700,007, 717,114, 718,901 are referred to.

Title: Improved thermionic-valve circuit for generating ultra-high frequency oscillations
IPC: H03L1/02
Filed: 1938-03-05
Abstract: 499,546. Valve generating circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 5, 1938, No. 6986. Convention date, March 8, 1937. [Class 40 (v)] In a short-wave oscillator in which variations in the supply voltage affect the frequency generated by varying the grid-cathode capacity in parallel with the tuned circuit, the effects of corresponding changes in positive-electrode and heating voltages are in opposite directions but those on the positive electrode normally preponderate. According to the invention, the fluctuations in the voltage on the positive electrode nearest to the control grid are reduced, so that the effect of these fluctuations is substantially compensated by the fluctuations in the heating voltage, by deriving the voltage on the said electrode from a potentiometer connected across the supply mains in series with a resistance the value of which depends on the applied current or voltage. As shown, the anode of a triode is supplied from a potentiometer 13 in series with a resistance 14 having a high negative temperaturecoefficient of resistance so that its resistance falls with increased voltage across terminals 11, 12 and the fraction of this voltage which is applied to the anode is decreased. In another arrangement, Fig. 2 (not shown), the potentiometer slider is connected to the screen grid of a pentode oscillator, and the elements 13, 14 are interchanged the latter however having a high positive temperature coefficient. As applied to the local oscillator of a superheterodyne receiver, Fig. 3 (not shown), the potentiometer slider is connected to the oscillator anode and to the screen grids of a frequency-changing octode.

Abstract: 796,521. Transistor pulse-delaying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 26, 1957 [March 8, 1956], No. 7309/56. Class 40 (6). In a circuit in which the output of a transistor X is coupled over a transformer T to the input so that when the circuit is triggered the transistor saturates, a differentiating circuit C1, R3 is connected across the output to produce a delayed pulse when the circuit reverts to its quiescent state. A negative-going pulse applied over isolating diode D2 causes the base potential to fall with the result that current flows in the emitter-collector path and the primary of the transformer T. The secondary winding of the transformer is so poled that the base is driven further negative and the transistor rapidly saturates. After a time determined primarily by the value of the resistor R1 and the inductance of the transformer T, the circuit restores regeneratively to its quiscent condition with negligible current flowing in the circuit. The negative-going pulse generated at the emitter is differentiated and fed to diode D3 which suppresses the negative-going pulse but passes the delayed positive-going pulse Fig. 2 (not shown). A resistor R2 biases the emitter slightly negative to prevent self-oscillation, particularly at high temperatures. The resistor R2 may be made temperature dependent or if this gives over-compensation the resistor R2 may be of normal type and a temperaturesensitive resistor connected between emitter and earth. In a modification feed-back is arranged between the collector and base.
