Title: Improvements in doors for vehicles
IPC: E05D15/50
Filed: 1929-10-16
Abstract: 335,755. Cavicchioli, G., and Ceschi, E. May 1, 1929, [Convention date.]. Hinges arranged to act altenatively at either side of door.-In a motor-vehicle door having locks and hinges at both edges so that the door may be opened at either side, the door is secured to the movable member of the hinge by the lock bolts. Each hinge comprises members 29 secured to the doorpost and a movable member 26 pivoted at 28, the two being biased to the closed position by springs 36 urging short lengths of cable 39 into housing sockets fixed in the door-post, the outer ends of the cables being tethered to the movable member 26. In the closed position of the hinge a closing movement of door slidably engages a lug 35 on the door behind a cranked lug 34 on plate 26, cones 33 on the door at the same time seating in recesses 32 in lugs 31 on member 26. Shooting of the lock bolts 4, 5 or 4<1>, 5<1> to engage apertures 30 in member 26 secures the door to the hinge. Two pairs of locks 2, 3, 2<1>, 3<1> with bolts 4, 5, 41, 5<1> shot by springs 19 are provided at opposite edges of the door. Bolt 4 is withdrawn by a follower 7 on a handle spindle 6, and the bolt operates a bellcrank lever 8 connected by a link 10 with a similar lever 11 which simultaneously withdraws bolt 5. Bolt 4' is withdrawn by a follower 7<1> on handle spindle 6<1>, an arm 8' being connected by link 10<1> with a lever 11<1> which simultaneously withdraws bolt 5<1>. A horizontal rod 13 is slidable in the casings of the locks 2, 2<1> and is provided with terminal heads 14 lying in the paths of the bolt tails, its length being such that when either bolt 4, 4<1> is retracted the tail of the retracted bolt moves the rod so that the head 14 at its other end abuts against the tail of the other bolt and prevents its withdrawal. When both bolts 4, 4' are shot a pivoted member 23 in lock 2 may be rotated by finger-piece 25 to bridge the gap between the left-hand head 14 and tail of bolt 4, to lock all bolts against withdrawal. Slidable bars 17 in locks 2, 2<1>, urged to shot position by springs 18, but normally held retracted by contact with corresponding hinge-members 26, are connected to pivoted catches 22 so that when the door is opened the freed bar 17 is shot and the corresponding catch 22 engages the end of rod 13 to hold it in the position in which it prevents retraction of the bolts at the opposite edge of the door. Thus, when the door is opened it is automatically secured against detachment from the operative hinge.

Title: Improvements in and relating to electronic counters
IPC: H04J3/04
Filed: 1948-12-06
Abstract: 654,616. Pulse frequency dividing circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Dec. 6, 1948, No. 31524. Convention date, Dec. 5, 1947. [Class 40 (vi)] [Also in Group XL (a)] The beam of a cathode-ray tube is arranged to progress from one target to the next of a multiple target anode under the control of applied pulses, a circuit between the output of the tube and the deflection circuit causing the beam to move alternately in one or the opposite direction. Assuming valve 30, Fig. 1, to be conducting and the beam to be between electrodes 19, 20, it will be swept rapidly to the right as the grid of valve 30 is driven negative due to the connection with bias source 64. Upon reaching electrode 20, the current through resistor 68 is off-set by the secondary electron current from electrode 20, the beam overlapping the electrode to the extent necessary to equalize the currents. A negative pulse applied to the grid of the cathode-ray tube cuts off the beam, the grid of valve 30 being driven more negative during the pulse so that when the pulse ends the beam passes between electrodes 20, 21 and settles on the left side of electrode 21. In this manner the beam progresses across the counting electrodes and finally strikes the reversing electrode 25. The resulting positive pulse causes the trigger pair 49, 50 to reverse, lowering the screen potential of valve 30 and raising the screen potential of valve 31. The rise in anode potential of valve 31 causes the beam to move to the left until it strikes electrode 24, whereupon the flow of secondary electrons restores the grid potential of valves 30, 31 to the potential they possessed at the commencement of the cycle when the beam rested on the edge of electrode 20. The grid of valve 31 is now driven negative during each pulse, the beam passing from right to left until the second reversing electrode 19 is struck when the trigger pair 49, 50 reverts. The counting speed may be decreased by increasing the capacitance to be charged by a capacitor 70. The counting electrodes may be in the form of a slotted strip, Fig. 2 (not shown), and may be applied directly to the end of the cathode-ray tube, Fig. 3 (not shown). In a modification, Fig. 5, particularly for counting pulses of random length the input is applied to deflecting plates 82, 83. The target electrode takes the form shown in Fig. 4, the beam A resting on the left edge of one of the lower projections 71. An input pulse causes the beam to rise and move to the right until it rests on projection 72, the beam passing- to the projection 73 when the pulse ceases. Reversing electrodes 80, 81 are provided. The input pulse may operate a trigger pair controlling the potentials of the deflecting plates 82, 83.

Filed: 1920-02-19
Abstract: 167,711. Schat, A. F. Feb. 19, 1920. Da.vits.-A lifeboat is suspended from slueing- davits by cables coupled with the davits in such a manner that the weight of the boat acting through the cables tends to force the boat outboard. Each fall 3 passes over a guide-pulley 4 on the davit and a guide pulley 5 on the deck and thence round a drum 6 to the drum 7 of a winch provided with a brake 9. The drum 6 is rotatably mounted on a member 10 secured to the davit, and is adapted to be secured thereto when operating the davit by a pin 15 inserted in one of a series of holes formed partly in the member 10 and partly in the drum 6. In a modification, the boat fall is passed round a pulley connected to a crank-pin on a disc secured to the davit so that the davit may be forced outboard by hauling in the boat fall.

Abstract: 1473162 Automatic current control BBC BROWN BOVERI & CO Ltd 18 July 1974 [20 July 1973] 31885/74 Heading G3R A control amplifier with a feedback capacitor has desired and actual value current inputs and an additional input connectable by switches to either a positive or a negative voltage source. The arrangement reduces response time when the desired input value changes. As shown, a control circuit for supplying the armature current in a D.C. motor fed from a converter includes an amplifier 2 receiving an actual current value input 8 and a desired current value input 7. A control device 12 normally holds switches 13, 14 open so that voltage sources 9, 10 are not connected to the amplifier. If the motor current is to be rapidly reduced, e.g. for reversing, switch 13 is closed so that positive source 9 is connected to the amplifier 2 to simulate a high actual current value and thus reduce the energization. To increase the current again, switch 13 is opened, and the return to a desired value is made more rapid by closing switch 14, thus connecting a source 10, of opposite polarity to the actual value current 7, to the amplifier input for a short time. In modifications, the amplifier feedback path may include a resistor (117), adding a proportional component to the integral characteristic produced by capacitor 3, Fig. 2 (not shown). The resistor (117) is shorted out when the switch 13 is closed so as to improve the response time. A diode circuit, Fig. 3 (not shown), or a reed relay, or a switching transistor such as a FET may be used to short out the resistor (117).
