Title: Plasma spray method and apparatus
IPC: C23C4/00
Filed: 1980-06-10
Abstract: A plasma spray apparatus capable of directing plasticized powders against a substrate for deposition of a protective coating thereon comprises a nozzles extension assembly (12) having a plasma cooling zone (28), a plasma acceleration zone (30), a powder injection zone (32) and a plasma/powder discharge zone (36) affixed to the downstream end of a conventional plasma generator (10). Various structural details of the apparatus described enable the attainment of high particle velocities without melting the particles. The technical concepts employed are directed to normalizing the temperature of the plasma stream at a reduced value prior to the injection of coating particles. A general reduction in temperature and substantially elimination of a thermal spike at the core of the stream are achieved. Coating particles are injected into the plasma stream only after the plasma is first cooled and then accelerated. Details of dimensions and operating conditions are given. <IMAGE>

Title: Method for producing penicillanic acid derivatives
IPC: C07D499/00
Filed: 1980-09-23
Abstract: Compounds of the formula I   <IMAGE> in which R1 stands for hydrogen, alkyl, alkoxy, halogen, or trifluoromethyl, and R2 stands for a carboxy group or for a protected carboxy group, in particular an esterified carboxy group; or, if appropriate, a salt thereof, are obtained by oxidising the corresponding penicillanic acid derivatives or their sulfoxides with hydrogen peroxide in the presence of a tungsten or molybdenum catalyst.

Title: Detection of arson accelerants
Inventor: SANGER DAVID GERALD
IPC: G01N33/00
Filed: 1982-03-12
Abstract: Vapour from fire debris is passed through a scrubber containing an oxidising agent such as acidified potassium dichromate absorbed in silica-gel granules to a flame ionisation detector. Commonly used arson accelerants, eg petrol and paraffin, present as constituents are relatively non-reactive and pass to the detector, whereas most of those vapour constituents which are not accelerants, but are detectable and so could otherwise mask the presence of accelerants, eg  alpha -pinene from wood, are relatively reactive and are absorbed in the scrubber.
Patent GB-2103052-A (GB)
Title: Radio receivers for use on frequency hopping networks
Inventor: DENT PAUL WILKINSON
IPC: H03G3/34
Filed: 1982-06-18
Abstract: In radio communications receivers for use on frequency hopping radio communications networks, the received signal in each hop period is analysed and assigned a quality value. If more than one signal is present during the hop period it is determined that more than one network has changed to the same frequency. Similarly if the received signal is out of synchronism it is determined that more than one network has changed to the same frequency. When more than one network has changed to the same frequency, the received signal is not output by the receiver but is replaced by an earlier (or later) received signal.

Title: Apparatus for the continuous investigation of chemical reactions by infrared (IR) absorption
Inventor: DORNER KARL HEINZ
IPC: G01N21/552
Filed: 1982-08-12
Abstract: An apparatus is disclosed comprising an IR spectrophotometer having a throughflow cell through which flows a continuous sample stream branched off from the reaction container. The cell consists of a cell body (14) and cell covers (15, 16), with inflow and outflow pipes (17, 18) and support (19) for fixing cell in the spectrometer. The cell chamber consists of a bore (20) with cut out portions (2) for receiving a crystal plate (11) and sealing supports. The crystal plate (11) is held free from tension inside the throughflow cell and the sample stream flows over the crystal plate in a direction substantially parallel to the crystal surface. The measuring light enters the sloped off end faces of the crystal plate (11), is propagated inside the plate by total reflection against the surfaces, and leaves through a similarly sloped off surface at the opposite end. The intensity of the emergent light depends on the physical conditions at the optical phase boundary of the crystal plate surfaces (11a, 11b). If in the course of a chemical reaction the reaction mixture is caused to flow continuously over the crystal plate (11), the progress of the reaction can be followed by means of IR spectroscopy by the on-line process. <IMAGE>

Title: Filter element
Inventor: BILLIET COLIN THOMAS
IPC: B01D46/24
Filed: 1983-10-11
Abstract: A filter element comprises coaxial inner and outer relatively rigid, permeable cylinders (5, 8), each cylinder being circumferentially continuous and sandwiched between the two cylinders, a spirally-wound cylindrical filter structure comprising a plurality of layers of microporous non- woven fibrous material (9), each pair of adjacent layers being separated by a layer of strong, fluid-permeable, flexible support material (10), the filter structure being under substantially uniform radial compression over the whole of its area. The compression is preferably such as to compress the filter structure by from 25% to 45% of its original thickness, and materially increases the efficiency of filters incorporating the structure. The element is made by forcing the cylinder (5), carrying the wound layers, axially into a tapered, thin- walled sleeve located within cylinder (8) and then withdrawing the sleeve. <IMAGE>
Patent GB-2149543-A (GB)
Title: Alarm system
Inventor: MORRISON JOHN MALCOLM
IPC: G08B27/00
Filed: 1983-11-08
Abstract: The system interconnects n stations and is such that an alarm initiated at any one station causes an alarm indication, with indication of source, at all other stations. Each station (Figure 4) comprises a 1-of-n decode counter (CD4017) clocked via comparator A1 by periodic signals on the common line and having outputs connected to n leds. Operating alarm button S1 on a given station causes a load R2 to be applied to the line during a time slot associated with that station, thus reducing line voltage in that time slot. The reduced line voltage is detected at all other stations by comparator A2 which, together with the decode counter, causes illumination of the led defining the alarm station. <IMAGE>

Title: Method of applying plastic labels on glass containers
Inventor: BURMEISTER ROBERT JAMES
IPC: B29C63/42
Filed: 1984-05-31
Abstract: Assembling thermoplastic sleeve coverings on rigid glass containers or bottles c and heat- shrinking the plastic covering on the container. The plastic is fed from a web 26 of material to a mandrel-carrying turret apparatus where it is cut into lengths and wrapped and seamed on successive mandrels 24, thereby forming sleeves. The bottles from a conveyor 10 are positioned over and in axial alignment with the sleeve-forming mandrels 24 and move synchronously therewith and the sleeves are telescopically assembled onto the glass bottles. The bottles are then rotated about their axes and moved through a semicircular heated zone 37 to shrink the sleeves into snug engagement with the surface of the glass bottle. After assembly and shrinking is complete, the bottles are released to an outfeed conveyor 24 completing the process. <IMAGE>
