Abstract: 850,312. X-ray tubes. LICENTIA PATENTVERWALTUNGS G.m.b.H. Jan. 2, 1957 [Jan. 2, 1956; April 7, 1956], No. 188/57. Class 39(1). An X-ray tube anode serving at the same time as a window, provided with liquid cooling and so dimensioned that its specific loading is not more than 40 W/mm<SP>2</SP> while the total anode loading is at least 2 Kw, is divided into individual sections by line-shaped or stripshaped reinforcements. In the construction shown the anode window 11, e.g. of copper, has a part-cylindrical surface and the cathode consists of a plurality of parallel heating coils 6 connected in parallel and having their axes on a cylindrical surface coaxial with the anode surface. A Wehnelt cylinder 20 modifies the shape of the equipotential planes such as 8 to prevent electrons impinging on the frame 22 of the anode window 11. The latter is provided with ribs 12 dividing the surface into a number of portions each opposite one of the cathode coils 6. The ribs 12 may be extended to the outer wall 18, e.g. of aluminium, thus dividing the cooling space into sections each of which may have its own connections at the points indicated by crosses 16. Alternatively the anode window 11 and/or the outer wall 18 may be corrugated and welded together to provide a plurality of cooling passages, Figs. 5-9 (not shown). In an alternative construction Fig. 1 (not shown), the anode window is a heat disc backed by a thin sheet of a heavy metal such as gold and divided into individual sections by ribs which project towards an outer cooling jacket. The cathode is a wire wound spirally to follow the surface of a section of a sphere. The anode window may also be curved to form a section of a sphere. The size of the radiation field may be varied for purposes of economy when irradiating objects of different sizes by providing a plurality of exchangeable cathode and/or anode systems or by electrostatically shielding or switching cathode filaments or parts thereof.

Title: Improvements in or relating to the production of stannous chloride
Inventor: VITTANDS WALTER ANDREJS
IPC: C01G19/06
Filed: 1958-01-02
Abstract: Stable stannous chloride solutions, which may be diluted with water, are prepared by reacting metallic tin with hydrochloric acid to form an acidified stannous chloride solution, for example by flowing concentrated hydrochloric acid over feathered tin, and then reacting stannous oxide with just sufficient of the acidified solution to dissolve the oxide.  The stannous oxide may be freshly prepared hydrated stannous oxide, which may have been prepared by precipitation from the acidified stannous chloride solution by an alkali such as sodium carbonate or bicarbonate, or the hydroxides of sodium, potassium or ammonium.  The diluted solution may be employed in the formation of corrosion resistant coatings on ferrous surfaces by first providing a phosphate coating and then contacting with the solution.  Specification 590,852 is referred to.

Title: Injection moulding machine
IPC: B29C45/82
Filed: 1946-01-03
Abstract: 605,677. Hydraulic presses. HERBERT, Ltd., A., BEBB, R. H., and JONES, L. N. Jan. 3, 1946, No. 235. [Class 69(ii)] [Also in Group V] The heater cylinder 20 is filled with moulding material in known manner, and compressed air is then admitted into a pipe 28 thus causing pistons 14 to lift the lower die-holder 15 into contact with the upper die-holder 38 and raise it, together with the cylinder 20 and injection plunger 17 which fits in the cylinder and rests on the material therein. Plunger 17 is fast with an abutment 39 and as 39 rises against springs 102 it opens valve 21, the plunger and abutment being then restrained from further movement. At the same time, a safety valve 36 is opened by a finger 40 so that compressed air is admitted into the right-hand side of an intensifier cylinder 37, whereupon liquid in the cylinder 44 is caused to apply high pressure to rams 12, 18, 18. The area of the ram 12 is greater than the total area of the rams 18 so that a high mould-closing pressure is applied and at the same time the cylinder 20 is forced upwards over the plunger 17 and the plastie material is injected into the mould. The operation is reversed by opening pipe 28 to exhaust and pipes 33, 49 to pressure. The moulding cycle may be repeated automatically, the pneumatic valves being operated by solenoids controlled by limit switches 46, 51, which are operated by fingers 47, 50. The liquid in the cylinder 44 is replenished during the mould closing stroke through a pipe 53 which leads to a reservoir, a valve permitting oil to flow from the reservoir, the valve being opened, to allow oil to return to the reservoir, during the mould opening stroke, by air pressure in the pipe 33.

Title: Improvements relating to the Preservation of Surgical Ligatures and the like.
Inventor: DAVIS CHARLES THOMAS
IPC: A61B17/06
Filed: 1916-01-06
Abstract: 102,511. Davis. C. T. Jan. 6, 1916. Disinfecting processes; disinfected articles, protecting - Surgical ligatures and sutures, for example of catgut, are sterilized by placing them in a a liquid contained within a glass tube and of such a nature that it will serve both for sterilizing the ligature during the process of heating the glass tube to expel the air before sealing, and also for the continued sterilization by heat after sealing and the subsequent storing. This method is stated to replace a former method consisting of sterilizing by immersion in a heated bath of cumene, C9, H12, after which the ligature was enclosed in a sealed tube containing a lighter and more volatile storing-liquid, such as chloroform or alcohol. The liquids selected have a boiling-point high enough to effect the sterilizing at an adequate temperature, and low enough to admit of rapid evaporization upon breaking the tube before use; they are also stable, unaffected by heat, light, or time, preferably water-repellant, and incapable of irritating human tissues. The benezene series of compounds, especially the lower methyl substitution products thereof, are used, including benzol, monomethylbenzene (C6, H5, CH5) or toluene, and the dimethyl products known as ortho-, meta-, and para-xylene. or mixtures thereof. The ligature is inserted in a glass tube, which is then dried and partly filled with the sterilizing and storing liquid, after which it is sealed and heated to a temperature above the boiling-point of the liquid to effect sterilization, and in all cases to above 100‹ C. For the liquids mentioned, the boiling-points range from 80 to 143‹ C.

Abstract: 1,206,571. Anchoring cables. B. A. BUKARKIN and V. N. KOVALEV. 3 Jan., 1969, No. 548/69. Heading B8B. A mechanism for coupling a pin 8 supporting a load to be lifted, to a lifting bracket 1 suspended from lifting cables, comprises a cage 14 movable within a housing 6, between positions in which an enlarged head of the pin 8 is free to move into and out of the cage, and is held fast in the cage. To engage the pin 8 ready for lifting, the mechanism is guided down a tensioned rope 9 coupled to the pin 8, and the head thereof rides up into a socket in the cage 14 displacing pivoted toggle plates 17 outwardly. The weight of the housing 6 causes compression of a spring 19 whereby the cage 14 effectively rides up into the housing 6 until the plates 17 pivot inwardly under the enlarged pin head to prevent removal thereof. The plates 17 pivoted to the cage 14 act as wedges between the housing wall and the pin head, and support the pin and its load as the housing is lifted. To release the pin 8, a spring plunger 21 is manually set to automatically spring into a recess 24 in the cage 14, once the load has been set down and the cage rides up in the housing 6, the cage is positively held in the upper position and the plates 17 may be retracted to release the pin head once the housing is lifted.
