Title: Secondary electron emitter
IPC: H01J1/32
Filed: 1953-04-15
Abstract: 728,181. Electrode materials and processing. RADIO CORPORATION OF AMERICA. April 15, 1953 [May 1, 1952], No. 10362/53. Drawings to Specification. Class 39 (1). A secondary emitting electrode consisting of a silver-magnesium alloy, which has a surface layer of magnesium oxide formed by heating in an atmosphere of water vapour or other oxidizing agent which does not diffuse into the alloy as readily as free oxygen, is then further treated by heating in free oxygen. The oxygen diffuses into the alloy and " freezes " by oxidation the free magnesium therein, so that it does not evaporate with deleterious effects during operation. The treatment can be carried out at temperatures from about 500 C. almost up to the melting point of silver (960 C.) for periods from 5 minutes up to half an hour or more, depending on temperature and pressure. The oxygen pressure is not critical, and can vary from a few mm. to several atmospheres. A suitable alloy consists of 98.3 per cent silver and 1.7 per cent magnesium. Other suitable agents for forming the oxide layer besides water vapour are carbon dioxide, nitrogen pentoxide, or alcohols. A suitable technique is described. Fig. 4 (not shown) illustrates graphically the improved emission resulting from the processing according to the invention.

Title: Track wrench
IPC: E01B29/28
Filed: 1945-04-26
Abstract: 595,736. Change-speed and reversing gear; friction gearing. NORDBERG MANUFACTURING CO. April 26, 1945, No. 10510. Convention date, May 4, 1944. [Classes 80(i) and 80(ii)] [Also in Group XXII] In a power - driven wrench for use on railtracks, a motor M drives the wrench - sockets 213 through a two-speed gearbox and gear - chains, a handle 163 and rod 160 being the speed-change control, and a handle 97 and rod 89 effecting a clutchcontrol. The gear-box 136, Fig. 17, has a multi-plate clutch 148 to each gearspeed 140 and 144 so that in operating the handle 163 the telescoped rod 160 is turned to move the member 154 and cause the drive to be selectively transmitted through one or other of the clutches. The gear-box housing is rotatably mounted so that the drive-torque reacts through an arm 165, Fig. 2, against a spring 173 which may be set to a predetermined overload. Deflection of the spring allows an extension 122 of the gearbox casing to move a sleeve 116, Fig. 19, along a rod 89 and trip the drive-control sleeve 100. The overload release may be rendered inoperative by a cord 180 moving a lever 175 to engage the arm 165. Rotation of the handle 97, Fig. 19, about the axis of the rod 89 rotates a fork 98 in which a roller 125 is located adjacent a second roller 125 situated in the fork 102 of the sleeve 100 keyed to the rod 89 thereby turning the rod 89 about its own axis. A crank 87, Fig. 9, at the other end of the rod 89 moves a member 81 laterally in either direction against spring pressure at 86, the member 81 being integral with the motor M. A friction-cone driving-member 131, Fig. 17, on the motor output shaft is therefore brought into contact with one of the two sides of a double-coned driven member 134 mounted on the gear-box input shaft 132 so that by turning the handle 97 the drive is made in forward or reverse directions, release of the handle 97 allowing springs 86 to return the motor to its neutral position, as determined by the adjusting nuts on a threaded spindle 84, and neutralise the drive. Under overload, the sleeve 116 and bracket 114 move along the rod 89 and cause a screw 112, or lip 110, to rotate the roller-support 124 whereby the sleeve 100 is freed from the restraining influence of the handle 97 and allows springs 86 to neutralise the drive. Specification 408,464, [Group XXII], is referred to.

Title: Improvements in arrangements in metering circuits of remote signalling systems
IPC: H04M15/10
Filed: 1949-04-20
Abstract: 680,625. Automatic exchange systems. TELEFON FABRIK AUTOMATIC AKTIESELSKAB, and UNGAR, E. April 20, 1949 [April 21, 1948], No. 10528/49. Class 40 (iv). In a system in which calls are metered in accordance with their duration and the nature of the connection obtained, apparatus is inserted in the metering circuit which receives the pulses normally transmitted at the commencement of a three-minute period and re-transmits them at intervals during the period to the subscriber's meter or to a coin control circuit as the case may be. In this way calls may be made for periods of less than three minutes at a lower charge. As shown, the metering pulses are received on lead Dfi and are repeated by ST to the driving magnet TAVK of a first uniselector TAV. Relay SO comes up for the duration of the train, and SK locks up to ground on B1 followed by SYA. The first two metering pulses received are also repeated by ST over the home contact 25, and contact 1 of bank TAV-b and lead Dfo to the metering circuit. When SO relapses at the end of the train, timed pulses from the source T are extended over bank TAV-d and step a second uniselector TCV at 5-second intervals. The first pulse is also extended over contact 25 of bank TCV-d to step a third uniselector TBV. The contacts of banks TCV-a ... TCV-d are cross-connected to those of bank TAV-c in such manner that during the stepping of TCV a number of the timed pulses equal to one less than the number of metering pulses received by ST are extended to operate SIC either directly or by means of SX. The first operation of SIC steps TBV and brings up SM, which locks up in series with SL when SIC releases, so that subsequent operations of SIC transmit setting pulses over Dfo. As TBV is stepped once at the end of the incoming train and once each time SIC operates, when the number of pulses transmitted over Dfo becomes equal to the number received by ST relay SS pulls up over TBV-a and TAV-a to stop further transmission. SS also releases SK and completes a circuit to home TAV, TBV and TCV in turn and bring up SH, whereupon SS and SH relapse in turn. During its advance when TCV reaches contact 24 the operation of SY releases SYA and TCV is stepped to contact 25 during its release period. Contacts 19 to 24 of bank TAV-d are connected to a second source t which delivers pulses at intervals of 2.5 seconds so that the larger number of pulses required may be retransmitted during a three-minute period.

Filed: 1936-04-14
Abstract: 472,419. Directional wireless signalling. JOHNSKE, F. April 14, 1936, No. 10774. [Class 40 (v)] In a direction-finding system the bearings are recorded in visual form, on a photographic film or the fluorescent screen of a cathode-ray tube, the incoming signals being correlated with the instantaneous position of the frame aerial. Vernier means are provided to increase the accuracy with which the bearings can be read. As shown in Figs. 1 and 2, a scale A, with red or blue markings for maximum and minimum, and a scale C marked in degrees, rotate with the aerial a, whilst a third scale B marked in degrees is fixed. Incoming signals are applied from a receiver e to a cathode-ray tube K mounted above a box containing a photographic filmf, which moves at right-angles to the plane of the paper. Below the box is a lamp l which projects the vernier radial markings of the scale C, on to the film f. The resulting record is shown in Fig. 3, the " dip " corresponding to the point of minimum reception. The scale C may co-operate with an auxiliary sliding ring which is set so as to mark on the film a line at right-angles to the plane of the aerial, Figs. 5 and 6 (not shown), so as to facilitate accurate reading. In Fig. 8, the aerial a is continually rotated, and the desired bearings are projected on to the screen of a cathode-ray tube k. Incoming signals are fed through a receiver e from the aerial to the cathode-ray tube k each time the aerial sweeps through a definite sector, which may be determined by opaque markings, Fig. 9, on a ring E which sweeps between a source of light and a photo-electric cell P. Simultaneously one plate Kd of a condenser pair sweeps over a second plate Ka so as to control the frequency of an oscillation generator h, the output from which is fed to the deflecting plates of the cathode-ray tube K so as to form a time base. The resulting record is again in the form of a " dip." Provision is made to throw the spot off the fluorescent screen of the tube before and after the aerial passes through a predetermined sector of exploration. The condenser plates Kd, Ka may be replaced by a photo-electric cell, Fig. 10 (not shown), the operation of which is controlled by opaque markings on an additional ring rotating with the aerial. The sector selecting ring may be adjusted so as to allow the pilot to " home " on to a beacon station, and to correct for wind-drift, and also for landing in fog or for automatic steering. Fig. 30 shows the cathode-ray indicating duration to port or starboard by the comparative lengths of the vertical traces X, Z. Specification 472,420 is referred to.
