Title: Improvements in or relating to magnetron oscillation generators
IPC: H01J25/54
Filed: 1934-06-14
Abstract: 442,776. Thermionic C valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and BENHAM, W. E., 88, The Ridgeway, Golders Green, both in London. June 14, 1934, No. 17660. Drawings to Specification. [Class 39 (i)] The magnetic field of a magnetron generator in which electronic oscillations take place is increased to at least a critical value at which, under dynamic conditions, electrons leaving the cathode with zero velocity arrive at the anode with zero radial velocity. This critical value is much larger than the value of the normal " critical field " and the transit time of the electrons is substantially increased as compared with the transit time obtained when the magnetron is operated in the normal manner with a magnetic field near to the normal " critical field." Formulµ for the transit time and critical value of magnetic field are given for magnetrons having plane and cylindrical electrodes, in terms of the electrode gap and anode-cathode voltage. In a modification, a split-anode magnetron is operated with a magnetic field much greater than the critical field as defined above, and of such a value that some electrons traverse paths, the radii of which increase suddenly when the electrons cross the space bounded by the planes passing through those edges of the anodes which define the split.

Title: Lubricating compositions
IPC: C10G71/00
Filed: 1955-06-20
Abstract: A corrosion-inhibiting lubricating composition comprises a major proportion of a lubricating oil and minor proportions, each of an aliphatic monocarboxylic acid containing 7-12 carbon atoms in the molecule, an oil-soluble phenolic compound and an oil-soluble aliphatic polycarboxylic acid substituted with an alkyl or alkenyl group containing 3-36 carbon atoms or an amide or partial ester of such a substituted polycarboxylic acid.  The lubricating oil may be a mineral or synthetic oil or a mixture of both.  Synthetic oils mentioned are olefine polymers, silicone fluids, organic phosphates and esters of polycarboxylic acids, such as di-(2-ethylhexyl) sebacate or adipate.  The aliphatic monocarboxylic acid may be saturated or unsaturated; the acids mentioned are normal heptanoic, octanoic, nonanoic, decanoic, undecanoic, and dodecanoic acids and also isononanoic and 3,5,5-trimethylhexanoic acids.  The phenolic compound may be an alkyl phenol such as 2,6-di-tert.-butyl-4-methyl phenol, 2,4,6 - trimethyl phenol, 2,4 - dimethyl - 6 - tert.-butyl phenol and 2,21-methylene bis-(4-methyl - 6 - tert. - butyl phenol). The polycarboxylic acid may be mono- or poly-alkyl- or -alkenyl-substituted and may be a C6 to C36 alkyl- or alkenyl-substituted malonic, succinic, glutaric, adipic, pimelic, sebacic, azelaic, tartaric, citric, maleic or citraconic acid. Alternatively, partial or full amides of the substituted polycarboxylic acids, such as the alkyl- or alkenyl-succinic acid amides, the alkenyl succinic acid mono-(-dicyclohexyl) amides and C16-alkenyl succinic acid mono-(2-ethylhexyl)amide, or partial esters of the substituted polycarboxylic acids, such as the mono-octyl alkylsebacates, the monobutyl alkyltartrates, ethyl decenylsuccinate and decyl isobutenylsuccinate, may be employed.  The lubricating composition may also contain, in minor proportion, an oil-soluble sulphur-containing compound (e.g. a sulphurized fat or fatty oil or derivative thereof, particularly sulphurized sperm oil, whale oil, oleic acid, linoleic acid or linoleic acid dimer), aromatic acids (e.g. benzoic, salicylic, mandelic or cinnamic acid), oiliness agents extreme pressure agents, anti-clogging agents and anti-foaming agents (e.g. silicone polymers).  Eleven examples of suitable mineral lubricating oil compositions are given.  For comparison purposes, similar mineral lubricating oil compositions are described in which the C7-C12 aliphatic monocarboxylic acid is omitted or replaced by n-hexanoic acid, and compositions are also described which consist of mineral lubricating oil and n-octanoic, n-nonanoic, n-decanoic, n-dodecanoic, palmitic or stearic acid.

Abstract: 907,948. Loading moving trains of trucks. GOODALL, CLAYTON & CO. Ltd. May 16, 1961 [May 20, 1960], No. 17784/60. Class 78 (4). As trucks c pass along a track t in a direction indicated by the arrow Y they are loaded by an endless - belt loading - boom 3, pivoted at 4, the delivery end of which is automatically lowered into and raised out of the trucks by truck-actuated mechanism 9. As described, the mechanism 9 is a pneumatic or hydraulic ram controlled by a member 14 pivoted at 15 and a similar member 13 (not shown), on the opposite side of the apparatus. When the member 13 drops off the end of a truck the ram 9 slowly raises the end of the boom and when the member 14 drops off the end of the truck the boom rises rapidly out of the truck. The end of the boom is now brought into register with a swinging shoot 16 by guides 18 and continues to feed material into the rear of the truck from which the boom has been lifted. When the next truck in the train raises the members 13, 14 the boom quickly descends into the truck and loading commences. The speed of the trucks is adjusted to the delivery rate of the loaded material by any known method. A cam 19 raises the boom by abutting the truck end in the event of a failure of the boom-raising means.

Title: Flocked heat transfer and method of making the same
IPC: B44C1/17
Filed: 1976-04-30
Abstract: 1510414 Transferring flocked patterns CHAMPION PRODUCTS Inc 30 April 1976 [5 March 1975] 17827/76 Heading B6C A flocked heat transfer is formed by applying a layer of heat-curable adhesive in a pattern to a thermoplastics film, applying flock to the adhesive pattern, placing an open-mesh carrier material over the flocked pattern, and heating the thus-formed sandwich while applying a vacuum to soften the thermoplastic film and draw it into the open-mesh carrier in the background areas. Substantially all the thermoplastics material in the background areas impregnates the carrier so that none is left on the surface of the carrier prior to transfer of the flocked pattern from the carrier to a final substrate, where the adhesive is cured. Fig. 5 illustrates a sandwich comprising release paper 12, thermoplastics film 14, heat-curable adhesive 20, flock 22 and open-mesh cloth 26 at a stage where the film 14 is being drawn into cloth 26 under heat and vacuum. Once release paper 12 is removed, the resulting transfer 21 comprises the flocked pattern on cloth 26, the pattern areas only carrying the thin film 14. Thus, no thermoplastics film moves across in background areas during the transfer application to a substrate.

Abstract: 700,719. Particle accelerators. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 15, 1952 [July 27, 1951], No. 17879/51. Class 39(1) In an electric discharge tube such as a linear accelerator in which the beam of charged particles is projected through a magnetic focusing coil, the coil is inside the evacuated container, comprises a small number of turns carrying a heavy current, and consists of tubing through which a cooling fluid is passed. In the travelling-wave linear accelerator shown the spacing between the turns of the coil 9 is progressively reduced along the beam path. The magnetic field may be enhanced by providing axially extending permanent magnets inside the container. For example a tranverse plate 15 of magnetic material and axial magnets 16 are provided adjacent the gun 1, or an annular magnet magnetized axially may be used. Local reduction of the focusing field may be effected by connecting shunts across certain turns. The coil 9 is carried on spacers supported by a perforated tubular insulating former 14. The former may however be dispensed with, the coil being carried by the leads 10, 11. The wave guide 6 feeds the travelling waves to the accelerator tube 2. The waves are fed back from the output end of the tube 2 by way of the wave guide 8, 7, shown broken.
