Patent GB-458914-A (GB)
Abstract: 458,914. Respiratory appliances. DRAGER, O. H., L³beck, Germany. Aug. 7, 1936, No. 21846. Convention date, Aug. 7, 1935. [Class 81 (ii)] In respiratory appliances comprising an oxygen-supply valve e connected by a lever to a breathing bag n, the lever is in two parts a, c hingedly connected at g, the part c having an extension b acting as a stop. The part a has a fork p engaging a button o on the bag and the part c a rearward extension c<1>, pressure on which by a manually-operated rod i opens the valve e independently of the bag action. The rod i slides in guides q, q<1> on the valve casing, has a terminal roller r, and a spring between the guide q<1> and a terminal knob. A set-screw on guide q, engaging a groove in the rod, prevents rotation thereof.

Abstract: 1,075,014. Extruding. STANDARD TELEPHONES & CABLES Ltd. Nov. 13, 1964 [Nov. 15, 1963], No. 46301/64. Heading B3P. [Also in Division H1] Apparatus for manufacturing a pre-impregnated oil-filled cable having an oversized sheath 16, e.g. of aluminium which is subsequently drawn or corrugated on to the cable core, has a double-walled tube 6 disposed within the extruding die 23 so as to allow impregnating oil 7 to act as a cooling medium between the cable core and the extruding die and the hot metal sheath. The cooling medium is formed partly by oil vapour 25 caused by the heat from the extrusion die and partly by a reverse flow of oil through an intermediate space 9 between the walls of tube 6. The oil vapour is prevented from entering the finished cable by a flow of oil 7 from the centre of tube 6 through slots 8 in the end of the tube into the intermediate space 9. The oil is obtained from an impregnating vessel 1 and is pumped from the space 9 through a cleaning and degassing system so as to return the oil to the impregnating vessel or to an oil reservoir. Water cooling is also applied at 24. To start the process, some sheath 16 is formed and the sheath, tubes 6 and 3 are evacuated by means of a vacuum pump 19 or 19<SP>1</SP> applied to an end cap 17 or to tube 3 respectively. A metal wire 22 is attached to the cap 17 and to the end of the cable core 21 so that the core is pulled through the extruding die as the sheathing process commences. In a modified extruder 2, Fig. 2 (not shown), which may fit a Schloemann aluminium press, the tube 6 is positioned so that oil leaving the intermediate space 9 passes between an outer water-cooled shield 27 and an inner tube before entering connecting tube 3.

Abstract: 1,168,909. Crop sprayers. BODENBEARBEITUNGSGERATE VEB. 17 Oct., 1967, No. 47301/67. Heading AID. [Also in Divisions F1 and F2] A plant protection appliance comprises a blower 8, the drive shaft of which is a subdivided universal joint shaft 3 situated in a tubular shaft tunnel 2 in the material container 1, there being universal joints 4, 6 at each end of the shaft and an intermediate universal joint 5 with a bearing 9 within the shaft tunnel. The bearing may be held in place in the tunnel by an elastic tyre like rubber body 10. In a modification, Fig. 2, the rubber body has a diameter slightly greater than the internal diameter of the shaft tunnel, and the body is held in position by its own elasticity. In a second modification, Fig. 3 (not shown), the rubber body is held on to the bearing by clamping rings, and screws may be tightened to deform the body when it is in place in the tunnel and cause the body to press against a seating in the tunnel wall. In a third modification, Fig. 4 (not shown), the rubber body may be secured in an airtight manner to the bearing and be supplied with an air valve (17). The body may thus be inflated when the bearing is in position to cause the body to press against the walls of the tunnel. Other materials may be used for the body 10, for example foam rubber.

Title: Production of secondary alkyl primary amines

Abstract: 1437893 Primary alkylamines; nitroparaffins TEXACO DEVELOPMENT CORP 1 Nov 1974 [26 Dec 1973] 47451/74 Heading C2C Secondary alkyl primary amines are made by (1) contacting a C 6-30  n-paraffin with nitrogen dioxide at a temperature of 270-400‹ F. and a pressure of 100 mm. Hg to 20 atm. in a plurality of reaction zones in series, with from 0À03 -0À4 moles of nitrogen dioxide per mole of n-paraffin being used in each reaction zone and wherein gaseous reaction products and water are removed from each reaction zone prior to being introduced into the succeeding zone whereby the total conversion to nitroparaffin is from 10% to 25% and (2) hydrogenating the resulting nitroparaffin. The output from the final nitration zone may be introduced directly into the hydrogenation or it may first be distilled or extracted with carbon dioxide in the presence of alcoholic potassium hydroxide or most preferably alkali-washed (e.g. in a countercurrent tower). Hydrogenation is effected at 100-450‹ F. in the presence of a catalyst, e.g. a metal of Groups 1b, V1b, VIIb or VIII or a compound thereof (e.g. copper chromite) which may be on a carrier (e.g. carbon, silica, kieselguhr or alumina). The amine is preferably separated from the crude hydrogenation product by admixing the latter with carbon dioxide to form an amine-carbon dioxide complex and thereafter contacting the mixture with an alkanol-water solvent which is saturated with carbon dioxide whereby the complex forms a distinct phase. The complex is then heated or subjected to a reduced pressure to decompose it. The by-products of the nitration and hydrogenation reaction may be hydrogenated and the resulting product recycled to the first nitration zone.

Title: Device for the automatic reading and evaluation of recorded curves
IPC: G07C5/00
Filed: 1974-11-04
Abstract: 1479744 Photo-electric record reading T V I-TELEVISION INDUSTRIELLE SA 4 Nov 1974 [16 Nov 1973] 47569/74 Heading G1A [Also in Division G4] To read information recorded in parallel tracks on a record carrier such as the disc of Fig. 2, the carrier is moved past a row of photo-cells arranged at right angles to the tracks. The cells are activated in turn by a sequence of clockpulses, which also control a counter having a number of outputs equal to the number of tracks. This counter permits the outputs of the cells to be correlated with the time in the sequence of clockpulses at which the outputs occur, and hence allow the outputs to be associated with particular tracks. The disc of Fig. 2 has four tracks I-IV; track I represents distance travelled, a distance of 5 km being represented by passage of the curve from the inner to the outer edge of the track; tracks II and III represent, for respective drivers, periods of rest (A) and of travel (C) and of other tasks such as loading (B); track IV represents vehicle speed. The thick curve C is in practice formed by rapid oscillations of the recorder pen, as seen in Fig. 3. The disc is either stepped or continuously moved beneath a row of cells 4, Fig. 1, by a support 2 and motor 3. In either case the row is activated by a sequence of rapid pulses from clock 6, so as to scan a field of view at right angles to the tracks; one such scan is shown at RA in Fig. 3, the next scan RB being at a position on the disc recorded one minute after the position viewed by scan RA. The clock 6 also activates a counter 7, having three outputs corresponding to tracks I-III, this embodiment does not read track IV; the first output 8 is activated during that portion of a scan lying within a band of track I, that band being WI in Fig. 3. Similarly counter outputs 108 and 208 are activated when bands WII and WIII are being viewed. These otuputs control AND gates 9, 109 and 209 so that during scan of WI the pulses produced by any cells which view the recorded curve pass to counter 10; similarly counters 110 and 210 receive pulses from such cells as view a recorded curve during scan of WII or WIII. The counters pass their outputs to store and evaluate circuits 11, 111 and 211 where the numbers of pulses received from the relevant AND gate 9, 109 or 209 are evaluated and printed. For Example, in circuit 111 which receives pulses representing the curve in WII, stores 12 and 13 distinguish signals produced by curve regions A, B and C in Fig. 3; region A produces only a single pulse from cells 4, and this produces an output at 14; region C produces at least 7 pulses from the cells, and hence an output at 16, while region B produces 2-6 pulses from the cells, and hence an output from 15. The signals from 14, 15 and 16 are gated into counters 21, 22, 23 for printing at 26, 27, 28, the signals from 14 being additionally processed at 24, 25 to see whether curve region A is at the beginning or end of the disc, in which case it represents night time resting.
