Abstract: 923,089. Electric analogue calculating. SOUTHERN PACIFIC CO. March 30, 1961 [April 4, 1960], No. 11741/61. Class 37. [Also in Group XXX] In a level crossing control arrangement (see Group XXX) computor means are provided for determining the time required for a train to arrive at the crossing when its distance from the crossing is known. A voltage analogue of the distance L is differentiated in unit 26 to obtain an analogue of velocity V which is then differentiated in unit 28 to obtain the analogue a of the vehicle's acceleration. The voltage L is inverted in circuit 34 and the resultant is doubled in circuit 36 to provide one input, equal to - 2L, to a summing amplifier 38, the voltage V is multiplied by a feedback voltage t in circuit 30 and the output of this circuit is doubled in circuit 40 to provide a second input, equal to 2Vt, to the summing amplifier and the voltage a is multiplied in circuit 32 by the square of the feedback voltage, obtained from multiplier 44, to provide the third input, equal to at<SP>2</SP> to the summing amplifier. The output of the summing amplifier 38 is amplified in high-gain amplifier 42 to provide the feedback voltage t. This feedback voltage urges the output of the summing amplifier (at<SP>2</SP> + 2Vt - 2L) towards zero, hence the voltage t is the analogue of the time required for the train to arrive at the crossing.

Abstract: 684,974. Aircraft undercarriages. DOWTY EQUIPMENT, Ltd., and CUSSONS, R. C. May 11, 1951. [May 11, 1950] No. 11804/50. Class 4. [Also in Group XXIX] An aircraft retractable and steerable nosewheel or tail wheel mounting comprises selfcentering means operating upon servo control mechanism of the steering motor of the mounting whereby to cause said motor to operate during retraction of the mounting to bring the landing wheel into a desired alignment. The invention is particularly applicable to an undercarriage having a steering motor servo control and follow-up mechanism of the type described in Specification 636,711 in which rotation of the spindle 11 under the control of the pilot displaces a servo valve of a hydraulic steering motor system to initiate operation of the steering motor to turn the steering column, which in turning, reacts upon the follow-up linkage of the mechanism to return the servo valve element to its neutral position. The spindle 11 carries fast therewith a radial arm 12 and a base disc 13. A C spring 14 engages opposed faces of the extremity of the arm 12 and is shaped to abut a projection 16 fixed to the retractable but non-rotatable part of the undercarriage mounting. The upper end of the spindle 11 carries an arm 19, provided at each end with an adjustable stop 21 which engages one face of a further arm carried by a pilot-operated shaft 23 co-axial with the spindle 11 and mounted in a bracket 24 fast with the aircraft structure. When the undercarriage is lowered the spindle 11 is controlled by the pilot-operated rod 25 through the connection 19, 21, 22 and if just prior to retraction about the pivots 18 the undercarriage is rotated out of a fore and aft plane, the C spring 14 will automatically restore the arm 12 and the spindle 11 to the neutral position as the members 19, 22 become separated and thus bring the servo motor into operation to correct the alignment of the undercarriage before it is fully retracted.

Abstract: 271,442. Darche, A. A. A. May 20, 1926, [Convention date]. Four-stroke-cycle engines.-At full load fuel is introduced during two stages in a complete cycle, the stages being made on different strokes of the piston. A small portion of gases are retained from the previous cycle and during the suction stroke the air-inlet valve is at first held closed; liquid fuel is injected into the residual gases and thereafter the air is admitted. This mixture is ignited and a second fuel injection made at the commencement of the expansion stroke to burn at constant pressure. The second injection of fuel may be advanced. Starting may be effected on a volatile fuel; output is regulated by decreasing the amount of fuel at the second injection, The Specification as open to inspection under Sect. 91 (3) (a) also states that the first drawn in charge may consists of a mixture of air and fuel. The combustion chamber may be connected to the cylinder by a channel of small cross-section, the fuel being injected into this channel. The volume of the combustion chamber may be varied by an auxiliary piston. This subject-matter does not appear in the Specification as accepted.

Title: Binary phase digital decoding system
IPC: H04L7/06
Filed: 1975-03-24
Abstract: 1476878 Data transmission; anti-phase modulation SINGER CO 24 March 1975 12166/75 Heading H4P  A decoder, for a system in which binary signals are converted into opposite pole pair pulse data signals for transmission associated with synchronizing opposite polarity pair pulses of different duration, has polarity detectors coupled to a sync. signal detector, both fed with strobing clock signals. At the transmitter (not shown or described) NRZ data is combined with 1 MHz clock pulse to produce bi-phase modulated data (Fig. to, not shown) which is biased to its mid value to give a series of symmetrical positive and negative equi-rectangular pulses (Fig. 1D) each pulse of sync. signals having a duration, e.g. 1À5 m./sec. which is greater than data pulse duration.  At the receiver opposite polarity pulses applied through NAND gates 14, 16 control cross coupled flip-flops Q10, Q11 comparing successive bit patterns and clocked by 8 MHz pulses from 18, outputs from which through NAND 20 are clocked into 10 stage sync. detecting register 22, output being to register 26 monitored by sync. signal decoder 28 providing separate complements of positive and negative sync. signals. NAND 20 also supplies data register 24 comprising clocked flip-flops Q12, Q13 output being to four stage register 30 providing a data output on 35 and monitored by data decoder 32 giving a data clock signal on 37. Input gates 14, 15 form a tri-state device zero input giving zero output which resets Q10, Q11 hence clears registers 22, 24. When the next input pulse reaches Q10, Q11 they will be set thus a 1 will be clocked along register 22; input to 22 must not change for at least 10 clock pulses in order for a 1 to issue therefrom otherwise register 22 will be cleared through NAND 20. Cross coupling of Q10, Q11 prevents both flip-flops changing together and both outputs must return to a 1 for one clock pulse thus reset will be applied to registers 22, 24 each transition so that sync. signals will be distinguished and recognized by Q10, Q11 remaining in an active state for at least 1À25 m./sec. and then change and remain in opposite state for another 1À25 m./sec. Each output pulse from register 22 disables gates 14, 16 and Q10, Q11 are set by the next strobe pulse since resetting registers 22, 24. Data register 24 has an initial zero inserted by NOR 36 to allow time for initial synchronization and then after at least two further clock pulses until a transition occurs, when register 24 is reset. The arrangement is described in greater detail in connection with Fig. 5 (not shown) certain components, e.g. register 22 of which may be of integrated circuit construction.
