Abstract: 930,149. Making lattice members; welding by pressure; shearing. EVG ENTWICKLUNGS - UND VERWERTUNGS - G.m.b.H. Dec. 12, 1960, No. 42701/60. Classes 83 (2) and 83 (4). In making a reinforcing element which comprises a pair of parallel strips with transverse pieces welded therebetween, the strips are conveyed to the welding station in converging directions, a succession of transverse pieces is introduced between the strips with clearance at both ends, the strips at the welding station are pressed from the outside by electrodes against each transverse piece in turn to weld thereto and the strips are moved forwards by a distance equal to the separation of the transverse pieces along the strips. Two strips 1, 11 are fed stepby-step from straightening rolls through guides 2, 2<SP>1</SP> to the welding station and rod or strip 3 is fed step-by-step through straightening rolls 5 and conveyer rolls 6 to a cutter 7 having a fixed knife 9 and a movable knife 10 which forms the connecting pieces 4, the strip 3 passing through a swingable guide 11 which after each cut returns the strip by a spring 12. The pieces 4 are fed forward in a guide 8 and with the strips 1, 11 stationary a piece is fed upwardly to the plane of the strips by a plunger 13 operated by a cam and moved by a lever mechanism towards a stop to clamp the piece. Electrodes 14, 14<SP>1</SP> connected to a transformer 18 are pivoted by cams carried on the shaft carrying the plunger moving cam, to press the strips against the piece and welding is effected. The reinforcing element is then fed one step by rollers 17 and the next piece 4 is fed and welded. The welding may be controlled by photo-electric means. Specification 728,866 is referred to.

Title: Process for the manufacture of pure, concentrated acetic acid from the reaction mixture obtained by paraffin oxidation
IPC: C07C51/46
Filed: 1962-11-23
Abstract: <PICT:0959875/C2/1> Pure concentrated acetic acid is prepared from the aqueous mixture obtained by oxidising aliphatic hydrocarbons in the liquid stage, by distillation in two stages, in the first, constituents passing over at below 106 DEG C. are separated from the azeotrope water/formic acid/acetic acid, and the resulting aqueous acid mixture is removed as a vapour phase which is distilled in the second stages with the addition of benzene as entrainer and the water/formic acid/benzene azeotrope removed as lead product followed by the removal of purified acetic acid in vapour phase over the sump of the second distillation stage. In the first stage the lead and sump products are recycled to the oxidising zone.  In a further purification stage the acetic acid may be hydrogenated, using noble metal a nickel on oxide catalysts to convert carbonyl impurities to alcohols.  A further two distillations under reduced pressure remove the ester impurities and yields a pure acid, while the sump products are recycled. An example is described in which the first distillation (column 2) is followed by a second distillation (column 5) with benzene as entrainer, hydrogenation using platinum on coal or silica gel, nickel on alumina a silica which may be contaminated with sodium or potassium oxides (column 7), followed by a third and fourth distillation (columns 8 and 10) to yield a high purity acetic acid.

Abstract: 968,540. Refrigerating. ELECTROLUX Ltd. Dec. 29, 1960 [Jan. 12, 1960; Jan. 30, 1960], No. 44580/60. Heading F4H. In an absorption refrigerator of the kind using inert gas and having two metallic heat transfer members heat conductively connected to the liquid circulating system for the absorption solution in the apparatus, each heat transfer member is associated with its own heat source, each source being able to operate alternatively. Either source can be used depending on the energy source available, whether it be gas, kerosene or electricity of different voltages. Liquid circulation pumps 30 and 31 fed from pipe 34 containing a column of rich absorption solution to level 14 are heat conductively connected to heat transfer members 33 and 32, respectively, over substantially the same height, so that in each pump the quantity of refrigerant vapour required for normal operation of the apparatus is generated in the absorption solution. Vapours leaving the top of either pump flow through branch 26 and into the liquid in pipes 34 and 36 to sufficient depth to be analyzed. The refrigerant vapour then flows up through pipe 13 to the condenser (not shown). The weak worm absorbtion solution leaving either pump flows into pipe 35, which is connected to liquid heat exchanger 37. The boiler system is essentially made of vertical pipes forming a compact pipe bundle enclosed in insulation 27. In a modification (Fig. 1, not shown), a single pump is in thermal relation with the flue and the sleeve for the electric heater. The gas flue may be a continuous pipe and the bubble pipe may be provided with a metal profile, which by a suitable screw arrangement is pressed against the flue pipe.

Abstract: 1,197,923. Alarm systems. GRANLEY PRODUCTS (LONDON) Ltd. 1 Jan., 1969 [3 Oct., 1967], No. 45067/67. Heading G4N. [Also in Division H4] An alarm system (e.g. burglar or fire) for automatically dialling a number and transmitting a message includes two records on a single carrier, one containing dialling signals and the other message signals with additional signals on one or both records which act to prepare the line for dialling, message sending and disconnection as required. The substation equipment is connected to telephone lines AB by relay A when a positive potential is applied at I/1 and motor 37 of a recorder is started. Tones recorded on both tracks of a tape are read by heads 16 (Track I), 15 (Track II) to operate relays B and C to loop the line for dialling. The tone on track I is interrupted and relay B follows to provide dialling pulses on the line, the tone on track II being maintained. After dialling is completed, the tone on track I ceases slightly before that on track II so that both relays B and C are de-energized and the contacts are in the positions shown. The line is now connected to transformer 12 so that the message on track II is transmitted. At the end of the message a metal foil on the tape shorts contacts 41 to open relay A and release the line. Monitor unit 31 detects if the line is engaged or broken and accordingly inhibits operation of relay A. Alarm 47 normally sounds after a delay provided by unit 48 unless the record does not start when interlock 49 will remain open and the alarm sounded immediately.

Abstract: 1325013 Colour television RCA CORPORATION 23 Sept 1970 [29 Sept 1969] 45309/70 Heading H4F [Also in Division G2] A colour motion picture film 15, Fig. 1 is encoded on to panchromatic black and white film 26 by inserting in the optical path a spatial colour encoding filter 24 having a repetitive pattern of red, green and blue (or cyan, magenta and yellow) strips, the transmissivity of these strips to white light being cyclically varied in a direction normal to the length thereof at a repetition rate which is a multiple or submultiple of the repetition rate of the coloured stripes. Subsequently when the encoded black and white film is imaged on to a television camera pickup tube 56, Fig. 4, a reference wave produced by the varying transmissivity of the colour encoding filter is separated 60 from the remainder of the generated phase and amplitude modulated colour carriers, multiplied in frequency 61 to form a reference wave of the same frequency as the colour carriers, and used to demodulate 62, 64 and 71 the colour carriers at the required phases to derive the three colour signals. Preferably the transmissivity of the stripes is varied at a spatial rate having a pitch equal to three times the pitch of the coloured stripes. As shown in Fig. 1 a brightness representative image of the colour film image is formed (21b, 29, 30) adjacent each encoded image on the film 26. Film position sensing means 19 is coupled to a conventional shutter 20 to actuate strobe lamp power supply 11 only when each frame of the colour film 15 is properly located. Adjacent each frame of colour encoded and brightness images on film 26 a hole is provided and during playback light from a blue lamp 58 is directed 51, 50 through these holes on to photo-cell 59 to trigger the stroboscopic lamp 46 when the film is in proper registration. In Fig. 4 the second pickup tube 54 detects the luminance or brightness image from film 26. A method of manufacturing the colour encoding filter is described.
