Patent GB-1082714-A (GB)
Title: Heat exchanger
Inventor: REAVES JAMES WALTER
IPC: F28D7/16
Filed: 1964-10-01
Abstract: 1,082,714. Gas heaters; recirculation of combustion gases. REAVES INDUSTRIAL FURNACES Ltd. Sept. 30, 1965 [Oct. 1,1964] No. 39995/64. Headings F4B and F4S. A gas (unspecified) flowing through a tube assembly comprising a helical tube 2 and straight tubes 4, is heated by an oil- or gasfired burner 16, the tube assembly being mounted on a base A surmounted by a casing B which is detachable for access to the tubes. The tubes 4 are suspended from the upper part of the casing by three tensioning devices 32. The gas to be heated passes from inlet 1, through the helical tube 2 and then through the tubes 4 to an outlet 5 for heated gas. The combustion products from the burner pass upwardly around the tubes 4, over the upper edge of a baffle 29 and downwardly over the tube 2 to a flue 19, the draught being assisted by a fan 18. A temperature sensing device 36 controls the temperature of the burner gases and prevents overheating. A valve 20 located adjacent a cold-air inlet 21 enables part of the combustion gases to be recirculated via the fan 18 and ducts 24, 25. Combustion air from a blower 6, and gaseous or liquid fuel, is supplied to the burner via a control valve system 7-11, mixing chamber 12 and fuel supply lines 13, 14. The casing B has attachments 31 for lifting purposes and a removable access cover 33. The tensioning devices are disconnected before removing the casing B. The top 30 of the casing may be separately detachable.
Patent GB-921063-A (GB)
Title: Colouration of polyolefin articles
Inventor: MCKENZIE DAVID FORBES
IPC: D06P1/92
Filed: 1960-11-22
Abstract: Articles containing or composed of polyolefins are dyed with a composition containing a cycloparaffinic acid or a derivative thereof.  The cycloparaffinic acid derivatives are salts which may contain a dyestuff as cation but the preferred salts are metal naphthenates, e.g. zinc naphthenate.  The composition may contain the dyestuff and naphthenate in undiluted form or the constituents may be dissolved in an aqueous or organic solvent.  Dyeing is preferably carried out at elevated temperatures and in a continuous manner.  The preferred articles to be dyed are filamentary or staple yarns consisting essentially of isotactic polypropylene.  The examples describe the dyeing of such yarn with a solvent dye (1) in white spirit as the solvent and (2) in white spirit emulsified in water.
Patent GB-1448741-A (GB)
Title: Optical communications systems
IPC: G01B11/00
Filed: 1973-08-24
Abstract: 1448741 Light guides POST OFFICE 13 Aug 1974 [24 Aug 1973] 40221/73 Heading G2J A coupler for light guides, e.g. fibres, comprises a glass sleeve having a straight bore with outwardly tapered end portions. The bore may contain an index-matching liquid.
Patent GB-1187686-A (GB)
Title: Improvements in Measuring Pourers
Inventor: HULSEL LEONARDUS MARINUS VAN
IPC: G01F11/26
Filed: 1968-08-27
Abstract: 1,187,686. Dispensing measured quantities of liquid. L. M. VAN HULSEL. 27 Aug., 1968 [6 Sept., 1967; 15 March, 1968], No. 40859/68. Heading B8N. A device for dispensing measured quantities of liquid from a bottle comprises an inner compartment 10 having an elongated opening 16, a body portion 11 including two outlets 15, and partitions 17 extending between the body portion and inner compartment. When the bottle is inverted liquid passes to the inner compartment via tube 19 and air passes into the bottle via a tube 18. When the liquid level in the compartment reaches the tube 18, flow of liquid stops. Return of the bottle to its normal position causes the measured quantity of liquid to flow into the body portion via the opening 16, and upon subsequent inversion of the bottle the liquid in the body portion will be dispensed and a further quantity of liquid will flow from the bottle into the inner compartment. A rotatable cap 12 comprises ears (12A), (Fig. 1, not shown), which in one position of the cap will cover the outlets 15.
Patent GB-957274-A (GB)
Title: Device for use with squeeze tubes particularly for cosmetic preparations
IPC: A45D40/26
Filed: 1962-10-30
Abstract: 957,274. Stripper devices. H. KAMBERSKY. Oct. 30, 1962 [Dec. 22, 1961], No. 41016/62. Heading B8D. A squeeze tube 1 for mascara or the like has screwed on to its neck 3 a sleeve member 4 having a bearing shoulder 5 and accommodating a resilient stripper 6. A cap 8 carrying an applicator stick 10 comprising a smooth cylindrical part 12 and a grooved part 13 fits over the sleeve so that the stick extends through the stripper into the tube and on removal of the cap the stick is pulled through the stripper which removes excess mascara so that only the grooves remain filled. In another embodiment, the sleeve member comprises two sections, one screwed on to the tube neck and the other of larger diameter surrounding the upper end of the tube to prevent unintended squeezing, and may be so dimensioned that an annular clearance is left between it and the neck shoulder of the tube.
Patent GB-1480511-A (GB)
Title: Trimetallic catalytic composite and its use for hydrocarbon conversion
IPC: C10G35/09
Filed: 1974-09-20
Abstract: 1480511 Hydrocarbon conversion catalysts U O P INC 20 Sept 1974 41032/74. Heading B1E [Also in Division C5] Catalysts comprise a porous carrier, metallic platinum or metallic palladium, metallic iridium, germanium in an oxidation state above that of the element and halogen, the platinum or palladium, iridium and geranium being substantially uniformly dispersed throughout the carrier. The catalysts may be sulphided and may contain an alkali or alkaline earth metal component and/or a Friedel-krafts metal halide.
