Title: Improvements in or relating to methods of detecting and measuring alternating electric potentials and electron discharge devices therefor
IPC: H04N9/26
Filed: 1940-09-12
Abstract: 567,228. Cathode-ray tubes. KLEMPERER, O. E. H. Sept. 12, 1940, No. 14131. [Class 39 (i)] In a cathode-ray tube deflection of the beam is effected by a pair of interleaved grids 3a, 3b, Fig. 2, which are connected to opposite potentials; the beam splits into two pencils, focusing at points 8a, 8b. A further system may be used giving deflation at right angles to that shown, the second system being formed by plates or interleaved grids ; in the latter case, four pencils will be obtained. The electrons are accelerated after deflection. The grids may be placed between two electrodes forming part of the focusing system or directly behind the electron gun. The grid wires may be circular, flat or elliptical in cross-section. The grids may be formed by winding round two sets of posts 11, Fig. 3, cutting away parts of the wires and deflecting the remaining part 12 as a whole ; the two are shown separated in this Figure. In another method, a soft glass rod 14 is laid on a metal plate 16 grooved at its back ; grid wire is wound round and the whole heated until the wire sinks in the glass ; the ends are then cut and alternate lengths connected.

Title: Improvements in or relating to ultrasonic inspection devices
IPC: G01N29/40
Filed: 1951-06-15
Abstract: 696,526. Ultrasonic inspection devices. SPERRY PRODUCTS, Inc. June 15, 1951 [Oct. 21, 1950], No. 14209/51. Class 118 (ii). In a pulse echo ultrasonic flaw detector, actuation of the indicator or recorder by spurious echoes having a time separation greater than the pulse recurrence period is prevented by applying the echo pulses to the indicator or recorder via a " cup and bucket" frequency divider producing a pulse output only in response to a predetermined number, e.g. six, of input pulses having a time separation equal to or less than the pulse recurrence period. As shown in Fig. 2 the frequency divider comprises a cathode follower 32 with a condenser 36, diode 38 and condenser 46 connected in series across the cathode load, the capacity of condenser 46 being much greater than that of 36. When a positive echo pulse is applied to the cathode follower, the voltages developed across condensers 36 and 46 are inversely proportional to their capacities and when the pulse terminates the right-hand plate of condenser 36 is restored to earth potential by diode 50 but the charge on condenser 46 is isolated by diode 38 and leaks away slowly through resistor 47 the process being repeated so that condenser 46 accumulates successive charges, Fig. 4, until the resultant voltage across it is sufficient to trigger the blocking oscillator 70 whose pulse output is applied to actuate a recording stylus 55. The resistor 47 is adjusted so that when spurious signals are received of lower recurrence frequency than the true echoes the charge on condenser 46 decays sufficiently rapidly to prevent a voltage build up across the condenser, Fig. 4, and the blocking oscillator is not triggered. The invention is described as applied to a system in which the receiver is gated on for a short period following the transmission of each pulse and a common transmitting and receiving transducer is coupled to the work piece by a wedge which is slidable over the surfaces thereof Fig. 1 (not shown). Since movement of the transducer causes spurious signals, the transducer may operate a generator 76 to produce a voltage which is a function of the rate of movement of the transducer and which is applied as cathode bias to the blocking oscillator 70. The recorder may be replaced by a cathode-ray oscilloscope.

Title: Fork-lift trucks
IPC: B66F9/20
Filed: 1972-03-27
Abstract: 1387670 Masted lift trucks F BENGEL A SAUTER and U SAUTER [trading as ALBERT IRION NACHFOLGER] 27 March 1972 [26 March 1971] 14285/72 Heading B8H In a lift truck control system provided with a push-button device for pre-selecting the height to which the load support is to be raised, a further device is incorporated whereby, for each shelf level pre-selected, the load support is raised to one of two heights associated with the pre-selected level in dependence upon whether or not the load support is carrying a load. As shown, a lifting-height detector 5 attached to the mast la comprises electrical contacts 21a, 21 urged towards drums 18, 19. An electrically conductive spring strip 20 having non-conducting markings corresponding to predetermined lifting-heights runs between the drums 18, 19. As the lifting carriage rises, the drum 19 is rotated by a belt or cable 7. In operation, on pressing one of the buttons 23 of a height pre-selector 10, the desired lifting height is set, two lifting heights being assigned to each button and two signals being registered. A sensor 3 on the lifting carriage detects the presence or absence of a load by means of a pivoted lever 2 and supplies a corresponding signal to the pre-selector 10 which then feeds the appropriate registered signal to a comparator circuit. The comparator circuit compares the chosen registered control signal with the signal from the contact 21, this signal resulting from a reference signal supplied to the contact 21a by the pre-selector 10. When the compared signals become the same, the comparator circuit closes an electromagnetic valve 8 in the pressure pipe 13 leading to the lifting ram. On returning a hydraulic control valve 11 to the neutral position, a sensor 9 emits a signal cancelling the signals registered in the pre-selector 10.

Abstract: 129,262. Schmid, A., (Assignee of Merk, L. A.). July 1, 1918, [Convention date]. Spray carburettors.- The load on the extraair valve is varied in accordance with the position of the throttle valve. Air enters the mixing chamber 7 past a valve 19 which has a lower guide-rod 20 sliding through a bush 21 which supports and adjusts the load in a supporting spring 24. An upper guide-rod 20<a> slides in a boring 25 in a plunger 26 which forms an abutment for the loading spring 29 and carries a roller 32 which bears against an adjustable cam 16 carried bv two arms 13, 14 on the throttle valve spindle 12. The cam is pivoted at 15 and its other end is slotted at 17 to work over a locking screw 18 on the arm 14. When the throttle has passed its fully open position, the load on the valve 19 is relieved so as to admit a large quantity of air and very little fuel, thus causing the engine to act as a brake. A hook 34 at the end of the cam prevents the throttle from being moved too far.

Abstract: 125,662. Vickers, Ltd., and Elia, G. E. Oct. 16, 1916. Mines, marine.-Relates to submarine mines A, Fig. 1, of which the anchor B contains a winch E for paying out the mooring-cable D. According to the invention, a motor is provided in the anchor to wind back a given length of the cable after the mine has risen to the surface and the anchor sunk to the bottom, in order to drag the mine down to a given depth. In the form shown, a spring drum H is used as the motor. The spring I, Fig. 5, is attached at its outer end to the drum H, and at its inner end to a sleeve J connected by a key J' to the shaft L, which is rotated by a detachable handle S to wind up the spring. A pawl V on the shaft bears against a ratchet-wheel U fixed to the anchor to prevent backward rotation of the shaft. The drum H is normally locked against rotation by a bolt T and is held against a spring 0 away from the winch E by a lever Q, which catches a flange R on the drum under the influence of a spring plunger G. When the anchor touches bottom, the plunger G is pressed in, and the released drum H is pressed against the winch E by the spring 0 and is clutched thereto by clutch members M, M<1>; the spring J then drives the winch back to the desired extent, until tha spring drive is exhausted or until a stopping-gear comes into play. The rotation of the winch E is checked by a brake E'.
