Title: Improvements in or relating to cavity-resonator magnetrons
IPC: H01J23/16
Filed: 1952-04-02
Abstract: 714,450. Magnetrons. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 2, 1952 [April 5, 1951], No. 8387/52. Class 39(1) A cavity resonator magnetron comprises an anode block 6, Fig. 2, including a projection 11 provided with a groove 12 extending into one of the cavities, and two end blocks, of which one is shown in Fig. 1. The end blocks are provided with ridges 4 on which the anode blocks rest, and with grooves 8 which accommodate the projection 11 and form with the grove 12 an output waveguide of H cross-section which leads to a rectangular waveguide formed by two further grooves 15 in the end blocks. The end blocks fit together with the faces 5 in contact and may be soldered together. With this construction there is less risk of solder flowing into the end spaces or into the H-section waveguide. Specification 714,452 is referred to.

Title: Improvements in or relating to sterile, broad-spectrum antibiotic-containing wound dressings
IPC: A61L15/46
Filed: 1952-04-03
Abstract: A method of prepairing a wound dressing comprises preparing a sterile mixture of a dispersing agent, anhydrous lanolin, petroleum, a wax, a mineral oil and a broad-spectrum antibiotic and sterilely adding the mixture to a sterile carrier.  The sterile mixture comprises 1-10 per cent. of glyceryl monostearate or other monoglyceryl ester of a long chain fatty acid, i.e. one which contains at least twelve carbon atoms in the molecule, or an ester of cholesterol, 5-20 per cent. anhydrous lanolin, 10-30 per cent. petrolatum, 5-20 per cent wax e.g. ceresin, paraffin wax or beeswax, 0.1 per cent.- 5 per cent. of a broad-spectrum antibiotic such as aureomycin, chloramphenicol, terramycin or their therapeutically effective salts and a mineral oil, the proportions being such that the mixture melts between 33 DEG C. and 44 DEG C.  The mixture may be made by sterilely preparing a mixture of the dispersing agent, lanolin, petrolatum and wax and adding it sterilely to a mixture of pulverised antibiotic and mineral oil. The resulting ointment is then applied to a sterile carrier e.g. gauze.  The finished dressing is sterilely heat sealed within an aluminium foil envelope laminated on the inside to a film of copolymer of vinyl chloride and vinyl acetate by a suitable adhesive. The term broad-spectrum used throughout the Specification covers antibiotics which are effective against both Gram-positive and Gram-negative bacteria e.g. tetracycline, chlortetracycline oxytetracycline bromotetracyline, chloramphenicol, streptomycin dihydiostreptomycin, viomycin, and neomycin.

Title: Improvements in or connected with two wheel trailers
IPC: B60P1/06
Filed: 1925-03-31
Abstract: 247,770. Eagle Engineering Co., Ltd., and Walter, J. March 31, 1925. Tipping-wagons.-A two-wheeled trailer which is tipped by the backing motion of the tractor is coupled to the tractor by a draw-bar 15 connected to a link 16 pivoted to the body 12 of the trailer and to a pair of rods 20 which are inclined upwardly and pivotally connected to a pair of cranked levers 21, the other ends of which are secured to a rod 18. On the backing of the tractor, the draw-bar, through the rods 20 and levers 21, starts tipping the body 12, the tipping continuing through this means until the link 16 has rotated into contact wih the body 12, as shown in Fig. 6, when the thrust of the draw-bar is directly transmitted to the body to complete the tipping. A leaf spring 25 is interposed between the body 12 and the cranked levers 21.

This insulated tip of this rod actuates alternatively the movable contacts 11, 12 of the switches in moving from one position to the other when actuating the beam deflecting mechanism, so that either contacts 8, 18 or 7, 19 are engaged. The circuit is shown in Fig. 4 with the lamp 36 and control switch 39. According to the Provisional Specification the lamp circuit controlled by one switch may comprise a resistance. to dim the light.

Filed: 1942-06-23
Abstract: 558,227. Hydraulic power transmission. WOODHAMS, P. G. June 23, 1942, No. 8568. [Class 69 (ii)] A hydraulic power transmission device for motor cars &c. of the kind in which the power shaft drives an annular member 8 filled with oil and the driven shaft is operated by a crank 12 connected by connecting rods 16, 17 to pistons 11 sliding in radial cylinders 2 of a cylinder assembly 1 is characterized in that a ported valve sleeve 9 is automatically adjusted by speedresponsive means to vary the fluid flow between the cylinders and the annulus 8 and so vary the speed ratio. The sleeve 9 is controlled by weights 20 on levers 21 which are controlled centrifugally and by means of links 24 rotate the sleeve 9 so as ultimately to close the inlets 10 thus locking the cylinder assembly 1 and causing equal speeds of the driving and driven shafts. When the inlets 10 are fully open no drive is transmitted, and in other positions the speed ratio varies with the extent of opening of the valve. The movements of the weights 20 are controlled by adjustable springs which resist the motions of the shafts 22. The automatic control of the sleeve 9 may be over-ridden by a handcontrol, and a set of gears may be used to set the driven shaft for forward, neutral, or reverse motion.

Title: Improvements in or relating to the purification of gelatin
IPC: C09H3/02
Filed: 1942-06-24
Abstract: 558,262. Gelatine. HART, J. A. H., and LEE, E. W. June 24, 1942, No. 8635. [Class 121] [Also in Group XX] Gelatine is purified by treating it in the form of thin leaf, flake or powder with a mixture of water, a water-miscible organic liquid which is not a solvent for the gelatine, and an acid which forms soluble salts with the impurities. The organic liquid may be methyl, ethyl or propylalcohol, acetone, dioxane or ethyleneglycol mono-methyl or mono-ethyl ether and is used in proportions which cause some swelling of the gelatine. The acid may be hydrochloric, nitric, acetic, lactic, maleic, benzoic, phthalic, benzene-, phenol- or salicyl-sulphonic or salicyclic acid, and may be used in an amount which brings the gelatine to its iso-electric point. If more acid is used, excess may be washed from the gelatine by treatment with water and organic liquid containing no acid. The purified gelatine is useful in making gelatine layers in photography, or making light filters. The solutions yield coatings, which adhere well to films made from organic colloids such as cellulose acetate or other esters. Solutions for forming sub-coats on a film contain purified gelatine, water, salicyclic acid, acetone, methyl-ethyl alcohol, and in some cases, nitrocellulose.

The test panel 14 carries a double-pole main switch 17, a series milliammeter 18 for showing any leakage current, and three push-button operated double pole switches 19, 20, 21. These switches connect the test circuit respectively between the lines 11,12 for testing the primary insulation, between the lines 12, 13 for testing the secondary insulation, and between the lines 11, 13 for testing the whole insulation. For checking the continuity of the test circuits the panel 14 also carries a socket 22 for receiving the test plug 10 and connecting the plug contacts 10a, 10k. For testing, the vehicle 1 is run on to a section 23 of trolley wire insulated from the rest of the system but connected thereto by normally closed switches 24 on the test panel. The switch 17 is then closed to connect the supply to the test circuit and to energize the operating coils of the switches 24 so as to disconnect the section 23. A lamp 25 indicates when the testing voltage is switched on.
