Title: Automatic steering apparatus for mobile vehicles
IPC: G05D1/06
Filed: 1952-11-04
Abstract: 759,479. Automatic steering control systems. BENDIX AVIATION CORPORATION. Nov. 4, 1952 [Nov. 23, 1951], No. 27757/52. Class 38 (4). The ratio of two control signals utilized for automatically steering a dirigible body is made a function of the position of the body relative to its destination. In an automatic aircraft landing system, Fig. 1, a localizer radio receiver 11 on the craft gives a D.C. signal of polarity and magnitude dependent on the sense and magnitude of horizontal deviation of the aircraft from a radiodefined course. This is converted by a modulator 20 into an A.C. signal of corresponding phase and magnitude, which, after amplification by valves 23, 31, 39 is applied to the input of a rudder servo-amplifier 92 and aileron servo-amplifier 87 through valves 78 and 77 respectively. The arrangement is such that the craft is restored to course by steering with appropriate banking. An anti-hunt signal is introduced by applying a signal dependent on horizontal deviation, obtained from secondary 29 of a transformer 27, directly to the grid of valve 39. The anti-hunt signal is normally neutralized by the voltage developed across a potentiometer 41 by an amplifier, including valves 45, 50, 51, 68, the input to which is obtained from the tapping of potentiometer 41. Upon change in deviation, however, the time delay introduced by heaters 55, 56 associated with temperature-variable resistors 62, 63 in a bridge circuit gives rise to a resultant anti-hunt signal. A limiter 80, as described in Specification 694,577 is associated with valve 39 to prevent extreme operation of the rudder and ailerons. A glide path radio receiver 10 on the craft gives a D.C. signal of polarity and magnitude dependent on the sense and magnitude of vertical deviation of the aircraft from a radio-defined descent path. This signal controls the elevators. At the same time that the elevator control is engaged by a switch S a solenoid valve V is operated by a switch S<SP>1</SP> so that a diaphragm 105 is effective with change of altitude during descent to operate potentiometers 107, 108. Operation of potentiometer 107 decreases the bias on the second grid 132 of valve 78 while operation of potentiometer 108 increases the bias on the second grid 121 of valve 77 so that there is more rudder and less aileron control, to produce flatter course,restoring turns as the aircraft descends. Operation of potentiometer 108 also increases the bias on the second grid 113 of valve 31 to maintain the aileron and rudder signals constant despite the fact that the aircraft is approaching the transmitter. Operation of potentiometer 107 also decreases the bias on the second grid 128 of valve 68 so that any anti-hunt signal increases as the aircraft descends. In a modification a pentode valve is substituted for triode valve 23 and pentode valve is substituted for triode valve 23 and pentode valve 31 is eliminated. Specifications 603,610, [Group XXXVI], 647,961, [Group XXXIX], 675,751 and 679,560 also are referred to.

In an hydraulic installation in a vehicle wherein a number of manually operated control units 3 each controls the flow of liquid from a pump 2 to a device 4 for adjusting a seat, roof, window or the like, each control unit has a switch 18 closed when the unit is operated thereby to start a motor 1 driving the pump 2, the starting of the motor being prevented if either a switch 8 which remains closed for a period after the vehicle has ceased to operate is open, or an ignition switch 7 is open. Each device 4 is in the form of a piston slidable in a cylinder having the connecting rod and thereof permanently connected to a line 9 from the pump 2. Operation of each unit 3 connects the full area side of the piston either to the line 9 or to a return line 13, and simultaneously operates its switch 18. Assuming either of the switches 7, 8 is closed, a relay 6 is energized to connect the motor 1 to a battery 5.

Abstract: Naphtha is reformed over a platinum-group metal catalyst at 875-990 DEG  F., 300-1000 p.s.i.g., 1-20 w./w./hr. with a mol. ratio of hydrogen to hydrocarbon of 3-50 to produce a net hydrogen make and the recycle gas composition is adjusted by removal of at least part of the net hydrogen make preferably so that there is a hydrogen partial pressure of 150-350 p.s.i.g. and a C1-C3 alkane partial pressure of at least 40% of the hydrogen partial pressure. This adjustment is effected by removal of hydrogen at any stage using a palladium diffuser; e.g. in multi-stage processes with a high paraffin content the hydrogen is removed before the first reactor, while with higher naphthene contents the diffuser may be placed after the first, second or third reactor.  C1-C3 alkanes may in addition be added at any suitable point or the recycle gas is separated into constituents by an absorption-desorption or fractionation process. Part of the recycle gas only may be passed to the first reactor and the remainder to the later reactors.

[Also in Division E1] Plastics cladding sheets for walls, floors and facades, and with mineral grains projecting from one surface thereof, are moulded by applying a layer of mineral grains, e.g. quartz, gravel, basalt, or marble chippings, within a mould to a horizontal layer of a silicate based slurry which is water soluble when set, the thickness of the slurry corresponding to half the smallest grain size of the mineral whereby, after setting the slurry, e.g. by heating the mould, and removing unembedded mineral grains by bringing the mould to a vertical position, a layer of plastics, preferably thermoplastics, is applied in a horizontal position of the mould to embed therein the mineral grains projecting from the slurry and, after the plastics has set, the composite assembly is taken out of the mould and the set slurry removed therefrom with water. The plastics layer may incorporate chicken wire embedded in sprayed plaster, or elements of concrete, expanded concrete, wood or metal.

Title: Improvements in or relating to Statistical Display Apparatus.
IPC: G09G1/10
Filed: 1967-06-20
Abstract: 1,166,387. Statistical display apparatus. DATRAN Ltd. and R. W. TAYLOR. 14 June, 1968 [20 June, 1967], No. 28489/67. Heading G4H. [Also in Division H4] A statistical display apparatus for displaying information about the magnitude of a variable comprises means for classifying the magnitude into one of a number of ranges and means for feeding a charge to a capacitor each time a sample falls in a corresponding range, means for periodically removing part of the charge on each of the capacitors and display means for displaying the magnitude of the charges on each of the capacitors. The input signal on line 46 is classified into one of eleven ranges by classifier 45 which may be as described in Specification 1,166,388. Timing generator 42 applies pulses to stepper 43 which enables in turn eleven coincidence circuits 48, also receiving the outputs from the classifier 45. The marked output produces a single pulse on lead 49 to close switch 33 and apply a charging pulse from source 34 to the appropriate one of a bank of capacitors, the corresponding relay contact 20, 21, 22 &c. being closed at the correct instant by switch control unit 40. Only one capacitor in each scanning cycles receives a charging pulse, all the others may receive a discharging pulse by closure of switch 35. At the same instant the charge on a capacitor is being adjusted it is also connected over lead 29 via a modulating switch 39 to a C.R.T. 37. The switch 39 is controlled by the generator 42 and connects the C.R.T. input to earth between the successive operations of the switches 20, 21 &c. The charges on the capacitors are therefore displayed on the C.R.T. as indicated. Instead of discharging the capacitors in each cycle, the charges may be accumulated for a set period from a constant current source so that the charge increases linearly rather than exponentially. A part of the charge on each capacitor is removed in each cycle. A chart recorder may be connected to line 29 in place of, or as well as, the C.R.T. 37. A signal from the coincidence circuits 48 may pass on lead 50 to the C.R.T. to indicate by brightening the beam, which capacitor is receiving the charge.
