Title: Apparatus for casting stereotype printing plates
IPC: B41D3/04
Filed: 1956-09-18
Abstract: 811,926. Sterotype plate casting apparatus. MIEHLEGOSS-DEXTER Inc. Sept. 18, 1956 [March 26, 1956], No. 15639/58.. Divided out of 811,925. Class 100(2) Stereotype casting apparatus comprises a mould box 15, plunger or core 16 co-operating therewith to define a mould space, means for supporting the plunger for movement between closed and open positions, a power actuator for causing movement of the plunger only after the latter has been moved manually to within a predetermined distance of its closed position and means for reversibly energizing the actuator to effect powered movement of the plunger from its closed to its open p o s i t i o n. The plunger 16 is supported an spaced frame members 18 having rails 18a on which run guide wheels 66 journalled in bearings 64 on brackets 60 which are fixed on opposite sides of the plunger 16 to sliding bar brackets 34 by bolts 61. The brackets 34 are bolted to the plunger 16 and carry a pair of sliding bars 35 which may be moved radially to seal the front-edges of the mould when the plunger is in casting position. The brackets 60 include depending. brackets 68 which are pivotally connected by pins 72 to links 70. The links 70 are keyed to a rock-shaft 69. The shaft 69 is rotated by an air cylinder 100 connected by a trunnion connection to the side frames 18 and including a piston rod 102 pivoted at 104 to an arm 105 rigidly connected to the shaft 69. The shaft 69 is fixed in bearings in the side frames 18 so that when the piston rod 102 is moved to the right as viewed in Fig. 1 the shaft 69 is rotated anticlockwise to position the plunger 16 in the mould box 15. The interior of the plunger 16 and mould box 15 may contain fluid passages for the circulation of liquid coolants. Operation of the air cylinder 100 is controlled by two solenoid operated valves which control the supply of air pressure to both sides of an enlarged end on the piston rod 102 which slides in the cylinder casing 101. The solenoids are controlled bv limit switches LS1, LS2 mounted on the side frames 18. From the horizontal position of the plunger it is manually shifted towards the mould box until one of the links 70 engages a roller 131 to operate the switch LS1. The switch energizes a solenoid to operate the valve controlling the supply of air to the left hand end of the cylinder 100 thus causing final positioning of the plunger to be power assisted. To retract the plunger a switch is provided which, when operated causes de-energization of the solnoid previously energized, and energization of a second solenoid controlling the valve for supplying air to the right-hand end of the cylinder 100 thus causing complete retraction of the plunger to the horizontal position under power until a projection 138 fixed to one of the brackets 34 operates switch LS2. Operation of the switch LS2 causes de-energization of the second solenoid thus restoring the mechanism to its original condition.

IPC: G05D1/06
Filed: 1970-04-03
Abstract: 1,270,754. 754. Automatic altitude control. BENDIX CORP. April 3, 1970, No.15865/70. Heading G3R. An aircraft is automatically controlled to capture and follow a flight path by signals computed from the present altitude, its rate of change, ground speed, distance from a future position, altitude at that position and the angle of elevation of the flight path at that position. In Fig. 1, an aircraft 2 flying at an altitude h b  is desired to capture a descent path CD making a predetermined angle of declination # relative to an aimpoint A at which the aircraft is required to level out at an altitude h a . During the approach, the difference between an altimeter signal and a signal from a selector set to the aimpoint altitude gives a signal h representative of the height of the aircraft relative to the aimpoint and this signal is subtracted from the height h c  of the descent path relative to the aimpoint as computed from the distance to the aimpoint and the predetermined angle of descent. The resultant signal he is continuously compared with the difference between the actual rate of descent of the aircraft and the rate at which it will descend at the same forward speed on the descent path. When the resultant of the comparison has a predetermined value at B, a logic circuit operates to apply the resultant to control the elevators so that the aircraft is caused to capture the descent path at E, maximum angular acceleration being kept to a safe value by suitable choice of circuit gain which varies in a non-linear manner with the magnitude of the control signal. After a delay, an integrator is connected to the rate difference circuit. The logic circuit rearranges the elevator control to cause the aircraft to follow the descent path during which the height relative to the aimpoint is continuously compared with the rate of descent so that, when the resultant of this comparison has a predetermined value at D, the logic circuit operates to apply the resultant to level out the aircraft until, at the desired altitude h a  a separate elevator control system is introduced by the logic circuit to maintain altitude constant. Automatic control of the aircraft to an aimpoint of higher altitude is referred to.

Abstract: 725,758. Fluid-actuated valves. BENDIX AVIATION CORPORATION. June 9, 1953 [June 23, 1952], No. 15876/53. Class 135. A valve for controlling a hydraulic motor 2 and of the kind having a movable valve member 6 which is operated by a handle 41 against the bias of centralizing springs 35, 36 to a position for admitting pressure fluid from an inlet 7 to one side of the motor and in which position it is held by a detent 47 engaging either of two grooves 45, 46 in the valve member until the motor completes its movement has the detent carried by a piston 48 which is subject to a pressure drop due to the flow of fluid to the motor. In the neutral position of the valve member, as shown, pressure fluid from a pump 3 is passed between lands 25, 26 of the valve member to a return passage 30. Upon displacement of the valve member to connect one of the passages 13 or 14 leading to the motor with the space between lands 27, 28, fluid flows from the inlet 7 through a passage 50 to a spring-loaded valve 57 and thence through passages 56, 51 to the motor, the pressure drop caused by the valve 57 acting on the piston 48 to hold the detent 47 in engagement with the valve member and prevent its return until the pressures on either side of the piston 48 are equalized by cessation of flow when the motor piston reaches the end of its travel. A passage 31 interconnecting the return passage 30 with annular recesses 21, 24 provides for exhausting either side of the motor. The valve may be simplified for use with a single-acting motor.

Abstract: 697,819. Television. HAZELTINE CORPORATION. July 5, 1951 [July 21, 1950], No. 15987/51. Class 40 (iii). [Also in Group XL (c)] In a television receiver in which the signal from the video amplifier 16, Fig. 1, and a gating pulse from the line amplifier 23 are applied to a stage 19 to produce an A.G.C. voltage on line 25, variations in output due to the change in relation phase of the inputs to stage 19 are minimized by the provision of a further shortergating pulse. Normally non-conducting valve 30 has a pulse A, Fig. 2, applied to the anode, at the time of occurrence of the synchronizing pulse B. A further pulse C is derived from pulse A over the differentiating circuit comprising capacitor 50 and resistor 37 so that the input to the grid of valve 30 appears as in curve D. Due to the bias network 32 only a small part of curve D is effective to produce conduction in the valve, curve E. The capacitor 47 is thus charged negatively to give the A.G.C. voltage while the network 32 biases diode 42 which only conducts during synchronizing signals. If the line time-base should run slow and give a pulse A<SP>1</SP>, the corresponding pulse D<SP>1</SP> is still as effective as D and gives a current pulse E<SP>1</SP>. In a modification, Fig. 4, the differentiated pulse is fed to the outer grid of the heptode 70 over the differentiating circuit 50, 71, 72, and the valve is held in a non- conducting state by the divider 62, 63. A pentode may replace the triode 30, Fig. 3 (not shown). Specification 697,821 is referred to.
