Abstract: 424,589. Bidets. HORNELL, P. G., 29, Humlegardsgortan, Stockholm. Aug. 25, 1933, No. 23706. Convention date, Aug. 26, 1932. [Class 26] In a bidet device of the kind comprising a jacket open at the top and bottom and a body from which liquid is directed in the form of a jet or jets into the body, the jet or jets issue from one or more openings in the body and outside the jacket, and are directed into one or more passages in the jacket wall. In the form shown in Fig. 2, the jacket 19 is secured to a member 1 arranged upon a body 2 having an internal bore with a connection 23 to a supply. The bore is provided with a seating for a spring-pressed valve 13 on a spindle 12 secured to the member 1 ; further on extension 3 of a handle 4 depends into a space 3c. When pressure is applied to the jacket or the members 1, 4 are drawn together, the members 1, 2 are moved relatively against spring-action so that the valve is moved off its seating and liquid enters the chamber 11 and passes to the jacket by way of apertures 16 and passages 22. Openings 24 are provided to prevent the formation of a vacuum between the body and jacket. In order to modify the direction or conformation of, or to disintegrate the jet, a baffle or baffles may be provided in the passage or passages in the jacket-wall or upon the supply body, the cross section of the passage or passages may be varied or the passages 22 are curved upwardly as at 22a. In another form one or a number of apertures may discharge through a slit in the jacket-wall, whilst in a further form, Fig. 8, the opening in the supply body is disposed beneath the jacket into which the jet is directed by a baffle 28 or by the opening itself. The Specification as open to inspection under Sect. 91 comprises also a form in which the aperture in the body is disposed above the jacket, and also a reference to Specification 380,225. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,042,042. Semi-conductor diodes; circuit assemblies. RADIO CORPORATION OF AMERICA. June 14, 1963 [July 11, 1962], No. 23867/63. Headings H1K and H1R. [Also in Division H3] In a magnetic memory comprising three generally parallel structures arranged one over the other, the centre structure comprising an array of magnetic elements arranged in rows and columns and the two outer structures each comprising corresponding arrays of coupling diodes also arranged in columns and rows, the outer structures are of semi-conductor material on which the diodes are integrally formed. A slab 310 of P-type silicon is processed with an N-type material and mesas 312 formed by a photo-etch method so that PN junctions 314 are obtained which are the coupling diodes of the memory. Insulating material 318 is coated over the semi-conductor wafer to form surface 316 and dots 320 of tin, lead, lead tin alloys are placed over the diode terminals flush with the surface 316. Antimony or phosphorus may be included within the lead. On the opposite surface 322 of the wafer 310 indium is alloyed or evaporated along lines 324 and serves as the connection to the anodes of the diodes. If diodes of opposite polarity are made the lands 320 are of indium, indium lead and may include a small amount of gallium or boron. The spacing between the PN junction and a conductor 324 is substantially less than the spacing between the PN junction and the next adjacent conductor 324 so as to eliminate crosstalk. In an alternative method of reducing cross-talk, Fig. 15 (not shown), the wafer of semi-conductor material is secured to a ceramic supporting substrate 330 and the semi-conductor wafer is cut between the lines 324 to completely separate the rows of diodes. Constriction of memory.-As shown in Fig. 7, the store is arranged in three blocks, upper and lower blocks 194, 196 of semi-conductor material carrying X o , Y and X 1  matrices respectively together with coupling diodes, and the centre block comprising the magnetic memory elements. The elements are made of doctor-bladed ferrite strips which are laminated together to provide a unitary structure, Figs. 6A-6K (not shown) in which two ferrite strips provided with metal conductors on one side are placed one on each side of a ferrite spacer strip and fired to produce a unitary structure. Small islands of indium, indium lead are deposited on top of the conductors, Fig. 10 (not shown), to servo as the connection terminals to the diodes in the wafers. Two dimensional arrays are made up by assembling rows parallel to one another separated by non-magnetic spacers. Metal spaces may be used to act as cooling fins. The upper wafer may include printed resistors.

Abstract: 842,853. Making channelled mould-plates; casting composite articles. VEREINIGTE LEICHTMETALL-WERKE G.m.b.H. Oct. 16, 1957 [Dec. 8, 1956], No. 24064/59. Divided out of 842,476. Drawings to Specification. Classes 83 (1) and 83 (2). In a method of making rolled-metal plates, e.g. for heating or cooling in moulding plastic materials, having passageways in one direction, rolling ingots are cast containing longitudinal passageways which, prior to rolling, are filled with a material having a melting point above the temperature at which rolling takes place, but below the melting-point of the casting. In making plates of AlMgSi alloy with fire-heating passageways, five oval aluminium tubes are embedded in a continuous casting. After machining the surfaces flat and casting zinc into the embedded tubes, the casting is longitudinally rolled down at 400‹ C. to a plate of 30 mm. thickness. The zinc is then melted out by heating the plate to 450‹ C., any traces of zinc remaining being dissolved by nitric acid. Alternatively the longitudinal oval passageways may be produced in the ingot by continuous casting, using the hollow-bar casting process as described in German Specification 908,521, the passageways then being cast full of zinc and the ingot rolled down as before. The plates may also be of AlMgMn alloy.
