Abstract: 506,287. Discharge lamps. SCHALLREUTER, W. L. W. Dec. 11, 1937, No. 34371. [Class 39 (i)] An electric discharge tube comprising a double walled envelope has a locating spider threaded over one or more wires leading from the pinch of the usual foot tube to the adjacent end of the inner envelope, the overall dimensions of the spider being substantially the same as the internal dimensions of the corresponding part of the outer envelope. The spider is preferably closer to the pinch than to the end of the inner envelope. In the form shown, the spider 23 has three arms and the hub portion ia passed over the stiff lead-in wire 16 to the electrode 14 and is located close to the pinch 26.

Title: Dish washer
IPC: A47L15/46
Filed: 1945-12-21
Abstract: 602,848. Washing dishes. ORNAS, H. E. S. H. AF. Dec. 21, 1945, No. 34684. [Class 138 (i)] [Also in Groups XIII, XXIX and XXXVII] In a dish-washing machine having a chamber for washing liquid, out of which by steam pressure the washing liquid is forced into a washing chamber where it is sprinkled over the dishes, a steam generator communicates, by means of a pipe controlled by a valve, with the chamber for the washing liquid, the valve being adapted to open at a predetermined steam pressure in the generator and to be closed at a lower pressure. The washing compartment 2 has supports 3 for the dishes and pipes 6 with perforations 5, mounted to rotate due to the liquid pressure. Washing liquid is poured into the compartment 2 and flows through an opening 11, controlled by a ball valve 14, and a pipe 12, into the pressure chamber 13. A separate steam generator 7 (see Group XIII) is filled to the desired height through a funnel 8, with water which is then heated by an electric heater activated by a float-actuated switch (see Group XXXVII). Steam from the generator passes through pipes 16, 17 to the chamber 13, forcing the liquid up the pipe 12 so as to close the valve 14 and thereafter through inlets 15 into a pipe 14a so as to spray the dishes through the perforations 5. The pipes 16, 17 are connected by a control valve 39 (see Group XXIX) which acts as a servomotor control system and whereby the steam is admitted to the chamber 13 intermittently so as to cause the dishes to be sprayed intermittently, and also successively to heat the washing liquid. When the water in the generator 7 reaches a certain low level, a float-actuated valve (see Group XIII) is opened and-hot water is led through a pipe 41 to rinse the dishes. Each time the steam ceases to press on the liquid in the chamber 13, liquid flows from the compartment 2 into the chamber, and air and steam escape through a hole 62 in the pipe 14a.

Abstract: 450,088. Insulatings, conductors, and cable joints. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., Hamilton House, Victoria Embankment, London, and HAMILTON, G. M., 252, St. Margaret's Road, Twickenham, Middlesex. Dec. 6, 1934, No. 35074. [Classes 36 and 38 (i)] A cable joint or other conductor enclosed in a housing is insulated by introducing into the housing a dry powder or granular body and a liquid which form a mixture (other than a mixture consisting of polymerized and unpolymerized styrene) of which the constituents interact in the housing and there form an insulating gel. Suitable combinations of materials are powdered or granular cellulose stearate and mineral oil, and powdered or granular polymerized vinyl esters and liquid unpolymerized vinyl esters, such as vinyl acetate and vinyl chloro-acetate. A filler, such as powdered silica may be added to the gel to increase its stiffness. In making a joint between two paper insulated cables 1, the lead sheath 2, metallized layer 3, and paper insulation 4 of each cable end are stripped back in the usual manner and the conductors are united by a ferrule 6. The supporting spiders 9 are then moved into position and the portions 7, 8 of the joint casing are wiped together and to the stripped back ends of the sheaths 2. The powdered component of the insulating gel 10 which is to fill the joint casing is then introduced into the casing through filling apertures 11, after which the casing is evacuated and the liquid component introduced.

A pneumatic tube container, for use in irradiating samples in a nuclear reactor, comprises a frontal closure and a weighted element freely mounted in the container behind the sample material within the container, the element being adapted to open the closure and expel the sample material upon impact of the container against an abutment at its point of arrival. In the arrangement shown a cylindrical container 1 is closed at one end of a metal membrane 4 and at the other end contains a weighted element 10 in the form of a piston attached to a piston rod 10a which extends through the end of the container. Tablets 6 of fissile material are supported by a cage member 7 with intervening spacer rings 8, and the free space is filled with an organic liquid which is to be iradiated. A punch ring 12 abuts the cage 7 and when the container is stopped at its arrival point after irradiation in a reactor, the inertia of the weight 10 causes the membrane 4 to be broken by the punch ring 12 and the contents of the container to be ejected. In alternative arrangements the closure member may be a lid opened by the piston through a lever or a rack and pinion, or it may be rigidly attached to the piston to form a kind of drawer. The material to be irradiated may be in powder, gas, or solid form.
