Title: Improvements in or relating to apparatus for transmitting short impulses of high frequency energy
IPC: H03K3/78
Filed: 1937-02-01
Abstract: 472,580. Wireless transmitting systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 1, 1937, No. 2952. Convention date, Feb. 1, 1936. [Class 40 (v)] Short impulses of carrier-wave energy for use in measuring distances &c. are produced by keying the grid circuit of a valve which mixes two waves of different frequency to produce a sum or difference frequency. As shown, two waves of different frequency are produced by the valve oscillators 1, 2 which may be crystal controlled, and are fed jointly to the grid of a mixing-valve 3, the output circuit L3 of which is tuned to the sum or difference of the two input frequencies. Keying is effected by opening a switch in the grid circuit of the valve 3. Owing to the different resonance of the input and output sides of the valve 3, errors in neutralization do not result in energization of the output circuit during " spaces." Amplifiers interposed between the mixing-valve 3 and the aerial may be subjected to simultaneous keying. Specifications 311,185, [Class 40 (v)], and 353,906 are referred to.

Filed: 1962-01-26
Abstract: 994,893. Clip fastenings. F. C. BLACKWELL & CO. Ltd. Oct. 16, 1962 [Jan. 26, 1962], No. 3158/62. Heading E2B. A wall box connecting clip comprises an elongated face plate 11 having on each of its longer sides two lugs 13 extending at right angles to the face plate and adapted to engage one face of one of the wall box walls and a third lug 14 extending at right angles to the face plate and located between the two lugs 13 and adapted to engage the other face of the same wall to enable the box wall to be clipped between the lugs 13, 14 and to enable two wall boxes to be held by the clip in spaced relationship, the space between the boxes being closed at the front by the clip. The plate 11 has at each end a flange 12 extending at right angles thereto to close the said space from the ends. The distance between the outermost edges 22, 23 of the lugs 13 is approximately equal to the inner length of the wall box wall so that the edges will lie closely adjacent to the internal faces of the contiguous walls of the wall box to prevent longitudinal displacement of the clip. Each of the lugs 13 has a notch 26 or 27 so arranged that two clips can be used at right angles. In a modification the lugs 13 each have an arcuate notch to reduce the depth towards the mid length of the clip to avoid masking apertures which are sometimes found in wall box walls.

Title: Improvements in and relating to arc lamps
IPC: A47H27/00
Filed: 1936-02-03
Abstract: 456,204. Arc lamps. OPTICOLOR AKT.-GES., Glarus, Switzerland. Feb. 3, 1936, Nos. 3231, 3232, and 3233. Convention dates, Feb. 1, 1935, March 19, 1935, and Dec. 24, 1935. [Class 39 (i)] In an arc lamp with luminous positive crater the positive electrode is closely surrounded by a closed cooled sleeve which extends substantially up to its burning end and prevents any access of air to the outer peripheral surface of the electrode at the burning end, and a magnetic field symmetrically surrounds the axis of the arc to steady the position of the crater. The arrangement is especially suitable for reflector arc lamps for lenticular element colour films. The magnetic coil may surround one electrode concentrically, or it may be divided into a number of coils distributed over both electrodes, or they may be laterally displaced so that the axis of the resultant field coincides with the arc axis. The coils may be in series or parallel with the arc, or a suitable combination of both kinds may be used. To reduce undesired flickering the magnetic field should have strong radial components to concentrate the arc. To this end the coil may be wound between two magnetic cylinders, preferably closed at one end to form a double walled pot surrounding the electrodes. If both electrodes carry coils, these should be arranged with like poles opposite each other, to produce radial components. Alternatively, the magnetic coil may be placed behind the reflector surrounding the negative electrode, or a U-shaped electromagnet may have one end enclosing each electrode. In one form described the core of a coil surrounding the positive electrode is hollow and water-cooled. The coaxial negative electrode carries an iron jacket, to concentrate the magnetic flux. In the form shown in Fig. 4 the coil 8 is made of hollow tubing through which cooling water circulates. The front portion 3 of the coil core is insulated from the rest of the core and from the electrode, to prevent the arc striking to it. A radial leakage field is produced by cutting away the front portion of the sleeve 4 surrounding the electrode 1. The negative electrode 2 carries a watercooled open-ended core 7, enclosing a coil 8. In the modification shown in Fig. 5, the coil 8 is enclosed in a pot-shaped core 7 situated in front of a water cooled sleeve 3, surrounding the cored positive carbon 1. To steady the arc still further, especially if flame arcs are used, a blast of air is blown from the chamber 5 through a nozzle 6. The air flows around the arc and is carried away through the passage 16, the combustion of any rare earths which may be present being completed. The flow of air through the casing 13 produces a partial vacuum at the holes 15 which draws away from the region of the reflector any particles thrown off from the electrodes. In a modification a separate pumping system is applied to the holes 15. A water-cooled casing 12 surrounds the negative electrode. Current is conducted to the positive carbon through brushes 11, springs 10 and the cable 9.
