IPC: H01J31/28
Filed: 1956-05-12
Abstract: 824,665. Electron multipliers ; cathode ray tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 8, 1957 [May 12, 1956], No. 14847/56. Class 39(1). An electron optical device comprises an electron emissive surface such as the photocathode 2, means such as the optical system 3, 4, for establishing an electron image at the surface, a first electrode 3, spaced from the surface 2, a second electrode 4 spaced from the first electrode 3, an electron image focussing field extending in the direction F, the potential of the first electrode being positive with respect to the surface and the potential of one of the electrodes varying periodically, whereby electrons emitted from the surface 2 are accelerated away from the surface so as to pass the electrode 2 and are then returned to the surface by a potential difference between the electrodes so as to strike the surface and to liberate secondary electrons therefrom substantially reproducing the electron image. As shown the voltage applied to the first electrode 3 is derived from a generator of positive going pulses and the electrode 4 is at a negative potential with respect to the surface 2. In an alternative embodiment the first electrode is maintained at a fixed positive polarity and an a.c. generator is connected between the first and second electrodes. The fixed potential of the second electrode can be maintained at such a value that a proportion of the secondary electrons pass therethrough and utilised, in the image intensifier shown, to produce an optical image on a fluorescent screen 5. If required the periodic variation of the one potential may be discontinued to cease periodically the liberation of secondary electrons. In a further embodiment the device is applied to a television pick-up tube wherein the photo-cathode is backed by a charge storage plate which is scanned in the normal manner, the charge on the storage plate being intensified by the liberation of the secondary electrons.

Title: Improvements in or relating to drilling, milling, screwing, tapping, and like machines having a rotary tool adapted to be moved to and from the work
IPC: B23B47/24
Filed: 1941-11-21
Abstract: 552,818. Drilling &c. machines. AERO PIPE & GLASS CO. Ltd., and ASPEEK, R. J. Nov. 21, 1941, Nos. 14973/41 and 11599/42. (Class 83 (iii)] Rotary tool spindle machines such as drilling, countersinking, counterboring, screwing and tapping machines have a hydraulic feed for the spindle by fluid in a reservoir to which pneumatic pressure is admitted above the fluid. When the control valve mechanism. is in position to feed the spindle for the cut air is also supplied to a driving rotor or vane wheel carried by the spindle. The drill head 17 carrying the spindle 20 in ball bearings is adjustably secured at 16 in an arm 84 adjustable radially and axially on the rod 10 of a piston 11 working in a double-acting cylinder carried on the underside of the cover 2 of a reservoir 3. Rotation of the piston is prevented by a pin 70. Fluid such as oil is supplied to the reservoir by an elbow 4, and pressure gas such as air is supplied at 61 to a passage 55 containing a valve 55. To start the machine the valve is depressed manually by a knob 72 to the position shown in Fig. 3 in which it is latched by a notch in the edge of a spring-pressed lever 78 having a knob 79 for hand actuation. In this position air passes by a port 62 and hose 25 to a nozzle 24 delivering a jet to a vane wheel 22. The spindle also carries a brake wheel 28. Air also passes down the valve to a pipe 53 delivering at 54 just below the cover 2. The resulting pressure on the surface 29 causes oil to flow by a port 42 communicating by manually adjustable needle valves 45, 46 with a port 41 delivering above the piston, descent of which is steadiedby limiting exhaust from below through a port 30 to the escape through a bleed port 37. Cam collars 50, 51 on the rod 10 are set to vary the rate of feed by a valve 49 that closes the port 44 of the valve 46. As illustrated and as applied to drilling a double walled article, the cam 51 causes a slow feed on starting, the valve 49 then opens, giving increased feed, and the cam 50 temporarily recloses the valve on starting to drill the second wall, or the cams may be set to give a reduced feed when breaking through. At the end of the feed stroke a stop 83 engages a cam surface on the lever 78 causing release of the valve 56 which then rises under the pressure below it to cut off air pressure from the port 62, thus stopping rotation of the spindle, and from the centre of the valve thus stopping the feed. At the same time ports 66, 67 are put into communication and the centre of the valve is connected with a small exhaust port 78 which may be valve controlled. Air then passes by a pipe 64 to the chamber 33 and oil passes freely past the ball valve 34 to the underside of the piston for the return stroke. Liquid from above the piston is returned to the reservoir.

Title: System for sorting data provided with addresses
IPC: H04M15/38
Filed: 1958-05-12
Abstract: 884,076. Sorting digital data. STANDARD TELEPHONES & CABLES Ltd. May 12, 1958 [May 11, 1957], No. 15146/58. Class 106 (1).  In electrical apparatus for sorting randomly distributed data items, each having an address having one or more address elements, into a natural sequence of addresses, the addresses are converted into sorting addresses comprising a multi-digit sorting number for each address element, and during successive sorting passes the data items are distributed to sorting storage devices in accordance with different sorting number digits. As shown in Fig. 1, items from a main store 1 are passed to a sorting distributer 5 comprising an input circuit 51, Fig. 2, which directs the whole of each item, after delay, to routing device 53, and the address only to identification circuit 52 which is controlled by line 75 from sequence control or programme circuit 7, including a counting device (not shown), so as to select and decode the operative sorting digit. In the apparatus of Fig. 1, each sorting digit is assumed to have only three possible values and the distributer 53, Fig. 2, is controlled so as to direct the associated data item over a corresponding one of three output lines 25, 35, 45 to a sorting storage device 2, 3 or 4. When a sorting pass is completed, the circuit 7 controls the read out of storage devices 2, 3 and 4 in turn for re-storing the data items via distributer 6 into the main store 1 in preparation for the next sorting pass. The identification circuit 52, Fig. 2, may comprise an address element selector 8, Fig. 3, followed by a sorting digit selector 9 which directs the selected address element to a code converter 10 or 11 for detecting the value of the operative sorting digit (each sorting number being assumed to have two digits). An example is described in which the addresses are 2-digit decimal numbers and the decimal digits 1-9 are converted into the 2-digit sorting numbers 11-13, 21-23 and 31-33 which can each be represented according to a 4-bit code. Sorting is then effected by 4 passes. Suppose, e.g., that an item has an address 36 which is converted to 13 : 23. During the first sorting pass, selector 8 will be set on the last address digit " 6 " and selector 9 connects 8 with converter 10 from which is obtained the sorting digit " 3." During the second pass, selector 9 is switched to converter 11 which produces the sorting digit " 2." During the third and fourth passes similar operations occur except that selector 8 is set on the address digit " 3." Special arrangements are described for dealing with the digit " 0." The main store may be replaced by a further group of sorting storage devices, the data items being transferred from one group to the other and back during alternate sorting passes. Other sorting mumber code systems for numerical and alphabetical characters are described ; the sorting numbers may be based on a radix of 2, 3, 4, 5 or 6. The data items may be stored on magnetic tape or drum stores.

Title: Improvements in burglar alarms
IPC: G08B13/22
Filed: 1926-06-17
Abstract: 274,622. Carpenter, G. B. June 17, 1926. No Patent granted (Sealing fee not paid). Burglar alarms. - In a constant current system of the type comprising a relay d for closing a local alarm circuit g, a tripswitch to establish a shunt across the relay terminals c, e, and a hand actuated local alarm circuit control switch n, the relay and trip-switch are located in an inaccessible position and the control switch is protected and located in an accessible position, being combined or associated with trip-switch setting means m. The tripswitch comprises a lever j connected by a lead a<2> to the protective circuit a and making contact with the armature c of the relay d. When the circuit a is closed by a switch a' operated by the final exit door, the armature c is attracted, the contact with the lever j is broken, and the tripping of the lever allows contacts o, p to be closed in a shunt g which may be provided across the circuit g. This shunt maintains the alarm bell i in operation even if the control switch n, which may be in the form of a lock, be tampered with. The system is re-set by the push m which energizes an electromagnet k, arranged in a shunt l across the circuit g, to raise the lever j. The protective casing s for the switches m, n is arranged in the circuit a, and a casing r for the relay &c. may be similarly arranged. A permutation switch with a small interruption range on each dial may replace the switch n. According to the modifica tion described with reference to Fig. 2 (not shown), the accessible alarm circuit switch is dispensed with, and the alarm bell is prevented from ringing only by continued energization of the electromagnet k under the control of an accessible trip-setting switch, which may be in the form of a permutation switch, each dial of which has a small contact range. In this case the local alarm circuit may be contained entirely within the casing r. According to the first Provisional Specification the trip setting means may be electrical or mechanical, or fluid-pressure operated, and a switch in the form of a lock giving a momentary closing of the setting circuit in its mid-position, as well as breaking the local alarm circuit during the day-time, is described.
