Title: Improvements in electron discharge devices
IPC: H01J25/12
Filed: 1942-10-30
Abstract: 561,911. Electron beam valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 30, 1942, No. 15290. Convention date, Oct. 30, 1941. [Class 39 (i)] In an electron discharge device having a cathode 11 and a collector electrode 15 and between them a pair of electrodes 19 and 20 spaced axially to provide a gap across which a high-frequency field may be generated for velocity modulating the electron stream, the electrode 15 has electron receiving surfaces 17 and 18 located at different distances from the cathode and means are provided to separate the slower and faster electrons so that they all arrive at the receiving surfaces more nearly simultaneously than if the latter were at the same distance. In operation the velocities of the electrons in the beam are cyclically varied by the field in the gap between electrodes 19 and 20 and the gap 26 in the input resonant cavity 25. A projection 21 from electrode 19 enters electrode 20 and thus a radial field is set up in electrode 20 which reverses its direction in unison with the velocity varying field in the gap. The faster electrons are diverted outwardly and pass through the annular space between tubes 22 and 24 to surface 18 whereas the slower electrons proceed axially within tube 22 and are received on surface 17. An output resonance cavity 27 is provided having a gap 28 between electrodes 24 and 15. The electron beam may be first modulated by a grid 13 and the velocity modulation superimposed on this.

Title: Improvements in or relating to grease-containers and grease-guns
IPC: F16N13/16
Filed: 1928-05-24
Abstract: 315,061. Appleby, J. A., and Wakefield & Co., Ltd., C. C. May 24, 1928. Reciprocating-cylinder pumps; delivery reservoirs. - The grease container 10 of the grease gun 29 is provided with a greasefollowing piston 13 which is urged forward by fluid air presume provided by a cylinder 21 when hand pressure is applied to its end cap. The cylinder 21 telescopes over the container 10 thus trapping air to provide this pressure at the same time as the hand strokes of the gun eject the grease as described in Specification 251,432. The cylinder 21 is returned to extended position by a suitable spring. When the grease is nearly exhausted the loose stem on the piston 13 contacts with a part on the grease gun, opening the valve 17 and so equalizing the air pressure on both sides of the piston 13 so that when the gun is being opened for refilling the piston 13 will not be forced out by air pressure. A valve 34 is lifted by its stem contacting with the nipple when ejecting grease but is spring closed on the back stroke to prevent air being sucked in. The piston 13 consists of. two cup leathers 14. A cup leather 24 makes a tight joint in the cylinder 21. Cylinder 21 draws air in through inlets 27 which are covered on the forcing stroke. A valve 25 allows air pressure to form the cylinder 21 to one side of the piston 13. Specification 219,004 also is referred to.

Title: Improvements in or relating to burglar alarm systems
IPC: G08B13/20
Filed: 1958-05-15
Abstract: 869,668. Burglar alarms. PRETINI, G. May 15, 1958 [March 16, 1958], No. 15666/58. Class 118. [Also in Group XVIII] The counter in a bank has a resilient mounted top so that when it is loaded greater than a predetermined extent, for example by a burglar climbing across it, it moves downwardly to break a hollow member containing a fluid -under a pressure greater or less than that of the atmosphere and so operate an alarm. In Fig. 2, the counter comprises a number of panels 2 having channel-shaped side members 4 which telescopically engage channel-shaped side members of the counter 6. The counter top is held away from the counter structure 1 by springs 3 but when a burglar climbs on the counter his weight is sufficient to cause the counter top to move downwardly so that a crossmember 8 will break a pipe 7 carrying fluid under a pressure greater or less than that of the air and so operate an alarm. In an alternative embodiment (Fig. 5), the counter top 9 has downwardly extending lips which embrace channel members 11 secured to the counter structure. The channel members support rotatable rods 13 carrying arms 17 which, under the action of a spring 20, urge the counter to an upward extreme, limited by members 24 and 25. The weight of the man will cause the counter top to fall slightly so that the lower pointed end of a rod 36 will puncture the membrane of a cell carrying a fluid under pressure (Fig. 6, not shown). The release of the pressure will cause the operation of an alarm. This could be effected by means of a valve system 31 connected to the cell through a tube so that the fluid pressure forces a membrane 32 against the wall of the cell and a rod 34 to its lowermost position. The release of the pressure will permit the spring to move the rod 34 upwards and so operate the alarm.

Abstract: 1,262,112. Rail and road ways. T. L. DANIELSSON. 25 March, 1969 [29 March, 1968], No. 15690/69. Heading EIG. Apparatus advanced by a mechanically propelled vehicle such as a tractor for distributing paving material on roads or pavements comprises a supply hopper 21 with its outlet disgorging into a chute 4 in which is mounted a motor driven feed screw 5 by which the material is delivered to a spreader, e.g. an open-bottomed box 8, the chute being mounted for powered reciprocating longitudinal movement on guides 9 on a base plate 10, e.g. on the power lift arms 3 of a tractor, extending transversely e.g. at right angles to the direction of vehicle advance. The chute may be moved by a reversible chain drive or a reciprocating piston. The bottom of the spreader box 8 or a separate stripper on the guides 9 determines the final depth of the laid material. To assist distribution the box may contain a vibrator and a distributing feed screw while if the material distributed is asphalt the chute may be heated. As shown the inclination of the chute is adjustable by a piston 12. The amplitude and the reversal of movement of the chute may be controlled automatically and sensing devices e.g. operating via hydraulic means may be provided to correct the chute inclination for deviations in the vertical distance between the spreader and a pre-determined height, e.g. a kerb when laying a footpath by a road, and to obtain a required inclination of the laid surface. Other sensing devices may be provided to maintain a chosen level of material in the chute. In a modification, (Figs. 6a, b, c not shown), the guide 9 which is pivotally mounted for adjustment of its inclination on a vertical plate secured to the tractor power lift arms extends over the whole path of travel of the chute, which is of only about half the length required in the Fig. 2 embodiment shown, and is telescopically retractable for transport under non- spreading conditions.
