Title: Recording system
Inventor: ASHBY ROBERT MORRELL
IPC: B64D45/00
Filed: 1959-12-04
Abstract: 909,900. Aircraft radar gun-sights; cathoderay tube displays. NORTH AMERICAN AVIATION Inc. Dec. 4, 1959, No. 41358/59. Class 40 (7). [Also in Group XXXIII] Relates to a pulse radar fire and flight control system for a fixed gun fighter aircraft in which the azimuthal and elevational components of the deviation of the aircraft heading from a desired pursuit course is indicated by the horizontal and vertical displacements of a luminous error spot 18 from the centre of a luminous reference circle 21 on the screen of a cathode-ray tube, the " time-to-go," i.e. the time that must elapse before the guns are fired, is given by the radius of a luminous " time-to-go " circle 20 as indicated by a time scale 20b, the rate of change of distance between the fighter and target is given by the circumferential position of a gap 20a in the circle 20 as indicated by an outer annular speed scale and the bank of the aircraft is indicated by the angular position of a luminous horizon line 19; the radius of the reference circle may also decrease as the time-to-go decreases. According to the present invention the pairs of x and y deflection voltages producing the error spot 18, the time-to-go circle 20, the reference circle 21 and the horizon line 19 are applied sequentially to the deflection circuits of the cathode-ray tube by means of relays controlled by a chain of three multivibrators, Fig. 6 (not shown), the electron beam is normally cut off and is intensified during the various deflection signals by corresponding intensity gating signals and the sequential x deflection, y deflection and gating signals are recorded on three separate channels on a magnetic tape driven by a motor which is energized only when echo signals are received from the target, Figs. 7, 8 and 9 (not shown). The recorded signals may then be subsequently reproduced to analyse the engagement. The range of the target is indicated by the vertical position of a deflection pipe on a vertical range trace 22 as given by the left-hand fine or right-hand coarse range scales and the azimuthal displacement of the target from the aircraft heading is indicated by the horizontal displacement of the range trace 22 from the centre of the screen. The range trace 22 is preferably produced continuously by applying the appropriate deflection signals to deflection members controlling a second electron beam of the cathode-ray tube and a D.C. range signal is converted to A.C. by chopping and filtering and is then recorded on a fourth channel on the magnetic tape, Fig. 9 (not shown). The range rate, time-to-go and steering error signals are derived, Fig. 1 (not shown), in a known form of computer from the radar range and the azimuth, elevation, azimuthal rate and elevational rate of the aerial automatically tracking the target; the steering error signals are then modified in accordance with the pitch and roll of the aircraft.

Filed: 1974-09-24
Abstract: 1430518 Coating apparatus XEROX CORP 24 Sept 1974 41414/74 Heading B2L [Also in Divisions D1 and G2] A doctor blade 1 is urged against an applicator roll 5 or other surface by means including a temperature responsive elements 14 comprising a fixed sealed expandible chamber 16 containing a temperature responsive fluid or wax. As shown a piston acted on by a rolling diaphragm seal 18 actuates the 'blade through a spring (not shown) 'and a member 22 either directly, (Fig. 2, not shown), or through a linkage (Fig. 3) including pivots P 2 , P 4  slidable in curved slots S 1 , S 2  to provide a non-linear relationship between the piston and blade movements. Advantageously the arrangement is used to meter liquid developer carried in grooves on the surface of the applicator roll 5 and applied to an electrostatic charge pattern carried on the surface of a photoreceptor drum 12 as the temperature and hence viscosity of the developer varies. A smooth transfer roll 10 deposits the developer in the small gap between the rolls 5 and 10 from a reservoir 11 which may house the temperature responsive element 14.

Abstract: 1,113,129. Transistor logic circuits. NATIONAL CASH REGISTER CO. 1 Oct., 1965 [2 Nov., 1964], No. 41770/65. Heading H3T. A logic circuit comprises: a first differential amplifier comprising transistors 10, 12 to which an input signal E is applied; a second differential amplifier comprising transistors 10<SP>1</SP>, 12<SP>1</SP> to which an input signal F is applied, the transistors 12, 12<SP>1</SP> having their bases and emitters cross coupled; a first output transistor 22 coupled to the collector of transistor 10; and a second output transistor coupled to collectors of transistors 12, 12<SP>1</SP> which produces the logical output EF + EF. When inputs E, F are both the same, i.e. both " 0 " or both " 1 " the cross coupled transistors 12, 12<SP>1</SP> draw very little current, and transistors 10, 10<SP>1</SP> draw a large current resulting in transistor 24 being cut off and transistor 22 conducting to produce a " 0 " output at J and a " 1" output at J<SP>1</SP>. If E is " 0 " and F is " 1 " transistor 12 is cut off and transistor 12<SP>1</SP> is conducting switching on transistor 24 to give a " 0 " output at J<SP>1</SP>. Transistor 10 is conducting and transistor 10<SP>1</SP> is cut off, but due to the shunting effect of resistor 91, these transistors have a lower common collector load than 12, 12<SP>1</SP> and transistor 22 is switched off to give a " 1 " output at J. If E is " 1 " and F is " 0 " the states of the transistors 10, 10<SP>1</SP>, 12, 12<SP>1</SP> are reversed leaving transistors 22 and 24 as before, i.e. J is " 1 " and J<SP>1</SP> is " 0." In a modification, lead 92 is omitted and a " 0 " input at E and a " 1 " at F switches on transistor 10 as before, in this case however, there is no shunting by resistor 91 and transistor 22 therefore switches on to give a " 0 " output at J. A " 1 " output at J is thus only produced when E is " 1" and F is " 0."

Abstract: 926,309. Coin-freed vending apparatus. STANDARD PACKAGING CORPORATION. Nov. 28, 1961 [March 6, 1961], No. 42506/61. Class 27. A coin-freed machine for vending cards contained in envelopes 32 has the envelopes suspended in groups on inclined rails 67 which are arranged in a number of parallel rows and a particular group is selected - by numbered buttons 21 and lettered buttons 23 which cause a carriage 47 to move sideways until it is above a selected row and then operate one of several trip levers 101 spaced along the carriage so that a single envelope is released from the group. The envelopes have hooks 93 stuck to them and pegs on the hooks ensure that they are spaced apart on the rails 67. A motor 55 and gear 57 engaging a rack 59 drive the carriage and the trip levers 101 are each actuated by a separate solenoid. After selection of a card in the display rack above the machine and insertion of a coin in a slot 27, the carriage 47, if not already in the extreme right-hand position, is returned there and operates a stop switch 125; the control buttons 21, 23 are also unlatched so that a selection can be made by the purchaser and the two depressed buttons are then latched in position. The carriage moves across until it operates a switch 119 in the row according to the button 21 and a trip solenoid is energized according to the button 23. The solenoid lowers a trip lever 101, Fig. 8, to tilt a release member 69 so that a forward limb 81 moves clear of the lowest hook and a rear limb 79 moves in front of the next hook, to hold up the remaining envelopes. The released envelope falls on to a plate 109 on a yoke 53 carried below the carriage 47 and operates a delivery switch to return the carriage to its right-hand position; subsequently, the envelope slides down a sloping floor 29 for delivery to the purchaser. If no card is available for delivery from the selected group, the delivery switch is not operated and the carriage continues to the left until it hits a reversing switch 121 and is then brought back to the right-hand position. Just before engaging the stop switch 125, the carriage closes an " empty " switch 123 and a lamp is illuminated to indicate that the purchaser should make another selection or have his money returned by pressing a button 28. Specification 926,310 is referred to.
