Filed: 1970-05-08
Abstract: 1305648 Saunas P BEMBERG 8 May 1970 [8 May 1969 29 April 1970] 22390/70 Heading A4N [Also in Division F4] A sauna cabin, large enough for a person to sit, stand, and move about therein, has airheating means 16 which is arranged so that heated air enters the cabin adjacent to the ceiling 3 thereof. A partition 8 is spaced from the floor 2, the ceiling 3, and from one side-wall 5 of the cabin to form a vertical air-shaft 9 which is widened at the top 15 to accommodate the heater 16 and which has an air-inlet 12 in the outer cabin-wall 5 through which ambient air is drawn to be heated and a corresponding aperture 10 for re-cycling cooled air from the cabin. One or more outlets 17 may be provided in the cabinwall 4 opposite to the air-shaft and may have sliding ventilators 18. The walls of the airshaft adjacent to the heater have a refractory lining. Any form of heater may be used, but, as shown, it is electrical. To humidify the air, steam-generating means may be incorporated. In one construction, Fig. 2, (not shown), this comprises an apertured tube mounted directly above the heater and through which steam or water may be passed. In another form, Fig.3, (not shown), a water-tray is mounted directly upon the heater element and water can be supplied to this tray by the user of the sauna, via a pipe passing through the partition and terminating in the funnel within the cabin. Perfumes or other desirable additives may also be supplied to the evaporator.

Title: Semi-conductor injection laser with confined recombination region
IPC: H01S5/40
Filed: 1975-05-23
Abstract: 1487479 Semiconductor lasers RCA CORPORATION 23 May 1975 [9 Oct 1974] 22586/75 Headings H1C and H1K A heterostructure semiconductor laser has a stripe active layer 24 between overlapping P and N type layers 14, 32 of higher bandgap material extending from one reflective end 14 of the semiconductor body 10 to the other, the P-N junction formed between a heteroboundary 24 or 26 of the stripe active layer, depending on the type of doping of this layer, providing a more favourable path for injection current than the monojunction between the contiguous layers 14 and 32 on either side of the stripe layer 24. The semiconductor structure is formed by epitaxial growth on a substrate 30, the stripe layer 24 being formed either by deposition over layer 32 and selective etching, or by deposition on to an unscreened portion of the layer. In a modification, Fig. 7, three parallel stripe layers 122 are provided. The layers 18, 22, 30 may be formed of GaAPAs and layer 24 of similar material of lower bandgap or of GaAs. Other suitable materials are InGaP for the layers 18, 22 and 30 and GaAsP or InGaAs for the active layer.

Title: Method of and means for filling bags of thermo-weldable material
IPC: B65B9/12
Filed: 1957-07-17
Abstract: 842,927. Packaging. PLASTUS S. A. July 17, 1957 [July 20, 1956; Nov. 24, 1956], No. 22638/57. Class 94(1). In a method of closing a filled theremoplastic sheet bag, the bag is clamped along spaced lines adjacent the mouth and the material heatsealed between the lines. Means may be provided to remove gas, air or part of the packaged product trapped between the lines. In some embodiments of apparatus for performing the method, Figs. 1-5 (not shown), jaws having resilient facings clamp the bag mouth about one or more filling tubes, and further jaws clamp the bag beneath the mouth, any trapped product being removed through the tubes. The heat sealing elements pass between the upper and lower jaws. In apparatus for forming a continuous succession of packages, two webs 12 joined along their margins by sealers 13 are gripped and sealed transversely, after filling with liquid from a nozzle 14, by members 19a, 19b, 20 on vertically reciprocating jaws 16. The jaws 16 may also advance the web. As the jaws close on the filled tube, it is clamped by the elements 19a, 19b, a needle 24 being gripped by the latter and pulled downwards relative to a fixed cylinder 26 as the jaws 16 descend. The needle 24 is attached to a piston 25, movement of which in the cylinder 26 causes liquid between the clamped areas to be evacuated. The sealing members 20 then advance to form spaced seals 21 between which the packages are severed. Plates 29 prevent undue bulging of the tube. In a modification on which solid products 30 are packaged, members 31 first contact the tube after filling. A pusher 32 and a suction plate 33 are brought into contact with the tube, the application of suction via passages 34 causing a needle 35 to penetrate the web. Air is then withdrawn from above the product by suction, and, if desired, inert gas introduced by the needle. Members 36 now clamp the tube and trapped gas is removed by the needle, followed by sealing by members 37. The tubes may also be formed by folding a single web or by extrusion.

Patent GB-701131-A (GB)
Title: Improvements in or relating to gas adsorbent by activation of acid sludge coke
IPC: C01B31/08
Filed: 1951-10-01
Abstract: Activated carbon is obtained from acid sludge coke (prepared as described below) by treatment with an oxidizing gas at a temperature of 1300 DEG  to 2000 DEG F. while maintaining the oxidizing gas at a partial pressure less than atmospheric pressure, i.e. by employing sub - atmospheric pressure when a single gas is used or employing a diluent such as nitrogen or refinery inert gas at atmospheric pressures and above.  Total pressures range from 2mm. vacuum to 6 atmospheres.  Oxidizing gases may be oxygen, carbon dioxide, hydrogen sulphide, sulphur vapour or steam and the activation is preferably effected in a fluidized bed.  Carbon dioxide may be used as a diluent at lower activating temperature when steam is the oxidizing gas.  The partial pressure of the oxidizing gas preferably ranges from 0.05 to 0.8 atmospheres and yields of 40 to 60 per cent. for steam, hydrogen sulphide or sulphur vapour, or 20 to 65 per cent. by weight for carbon dioxide are optimum.  Activation times may range from 10 minutes to 3 hours.  The acid sludge coke employed is obtained by carbonising the tarry acid sludge by contacting it in the absence of air with a mass of hot cake maintained with continuous stirring at a temperature of 400 to 750 DEG F. to distil off volatiles.  The carbonized sludge is then transferred to a kiln and partially burnt with air at a temperature of 650 DEG F. to 1200 DEG F. for 5 to 25 minutes.  The bulk of the resultant hot coke is recycled and the remainder, about one-seventh, is removed as product and treated according to the invention, to produce an activated carbon particularly suited to absorption of C1 to C5 fractions from refinery fuel gas; to the recovery of light ends from low pressure catalytic cracking gases; to the separation of methane from nitrogen and hydrogen; to the recovery of acetylene from the Wulff process gases; to the separation of oxygen from air and to the recovery of hydrocarbons from coke oven gases. Specifications 586,766 and 693,502 are referred to.

Abstract: 357,703. Inserting and extracting liner sleeves. BAKER, R., Roseberry Street, Toowoomba, Queensland, Australia. July 29, 1930, No. 22849. [Class 61 (iii).] Sleeves are extracted from and inserted in valve chests of locomotives &c. by a rod 18 attached to a plunger 3 of a hydraulic cylinder 1, the movement of the plunger 3 being effected by fluid transferred from the rear to the front of the plunger by pumps 4 driven by eccentrics 8 from the shaft 7. The fluid passes through suction pipes 10 and valves 5 and is forced through valves 6 to the delivery passage 11. When the operation is complete a release valve 15 is slackened allowing the fluid to return through pipe 12 to the rear of the plunger 3. In use, the plunger rod 18 is secured to the back-plate of the valve chest behind the sleeve and the flange of the cylinder 1 is placed against the stop plate which abuts the flange of the valve chest and is held in position by the studs and nuts.
