Title: A Safety Closure Assembly, in particular for Butane or Propane Bottles
IPC: F17C13/12
Filed: 1967-07-17
Abstract: 1.152,890. Pipe coupling arrangements. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 17 July, 1967 [18 July, 1966], No. 32809/67. Heading F2G. A safety closure assembly, particularly for use as a supplementary coupling arrangement for connecting a pipe or pipe piece, e.g. associated with a pressure-reducing valve, to a bottle containing gas or liquefied gas, e.g. liquefied butane or propane, under pressure, comprises a closure member 12 slidably arranged within a tubular coupling body 1 acting as a combined inlet/outlet for the gas, the closure member being provided with a stop element 2a cooperating with a stop element, e.g. the shoulder 1c, on the body, and elastic means, e.g. the compression spring 3, arranged to push the closure member into a position where the stop elements contact each other and an end surface 2b of the closure member lies in the same or approximately the same plane as that of the free end of the body 1, sealing means 5 being arranged in the body to seal the closure member. When used in combination with a manual valve (not shown) on the gas bottle, the assembly allows the insertion into the body 1 of a pipe piece (6, Fig. 2, not shown), without the need to close the manual valve and without creating an air space which would otherwise dilute the initial flow of gas, the flow being suitably restricted since the gas is forced to pass through the narrow gap 1a between the closure member and the body, whereby gas loss on disconnection of the pipe piece is also minimized. When a pressure gas pipe (8, Fig. 3, not shown) is attached to the coupling, the closure member 2 is forced down by the gas pressure until spring 3 is fully compressed, so that flow into the bottle is unrestricted. In a modified assembly, Fig. 6, the closure member 12 is associated with a flowcontrolling valve 10 provided with a conical seal 10a ensuring complete sealing of the bottle in the absence of a manual valve, one spring 13 being arranged between the closure member and the valve 10 and another, stronger, spring being arranged between the valve 10 and the body. A rod 21a associated with an outlet pipe 21 is used to open the valve and closure member manually, as shown, to provide a restricted flow during delivery of gas, while during filling of the bottle the inlet pressure forces the valve and closure member to their lowest positions to provide unrestricted flow, as in the previous example.

Title: Drying oils
Filed: 1933-11-24
Abstract: In the production of drying oils by polymerization, and removal of unpolymerized and unpolymerizable matter by evaporative or molecular distillation in a high vacuum as described in the parent Specification, fish oils with an iodine value above 120 are treated. Menhaden, Japanese sardine, herring, and Canadian pilchard oils are specified.  The oils are polymerized, e.g. by blowing hot, by heating in presence or not of air, catalysts, or driers, by ultra-violet light, or by silent electric discharges. For example, 1000 kg. of Japanese pale sardine oil is heated to 290--300 DEG  C. at 2--5 mm. until the iodine value falls from 174 to 103; the polymerized oil is then passed at 240 DEG  C. through the distilling apparatus under high vacuum described in Specification 315,186, [Class 91], whereby 290 kg. is removed.  50 Kg. of the product is mixed with 26 kg. of xylene and 1.25 kg. of 4 per cent cobalt linoleate to form a varnish drying in 8--20 hrs.  Or 1000 kg. of Japanese sardine oil is maintained at 290--300 DEG  C. in an atmosphere of carbon-dioxide until the iodine value is 110, and is then distilled at 225--230 DEG C., 420 kg. being removed. Specifications 15012/12, 6463/13, 121,777 and 196,623, [all in Class 91], also are referred to.

Abstract: 878,836. Automatic current control systems. INSTITUT FUR SCHIFFBAU-ROSTOCK. Oct. 16, 1958, No. 33039/58. Class 38 (4). [Also in Group XXXVII] Opposing field windings 5, 6, of a Ward Leonard generator 14 are supplied from an induction regulator 1 through a saturable choke 2 having a pre-magnetizing winding X, the speed and direction of motor 13 being dependent upon angular adjustment of the regulator. If the motor tends to become overloaded, a currentresponsive voltage U x  exceeds a bias voltage from potentiometer 9 so that magnetic amplifier 10 energizes a counter-magnetization winding Z of the choke 2. This reduces the excitation of the generator and keeps the motor current at its rated value.

Title: Improvements in or relating to the manufacture of polymeric materials
Inventor: IBBOTSON ARTHUR
IPC: C08J9/14
Filed: 1959-10-02
Abstract: The invention comprises the improvement in or modification of the process for the manufacture of foamed polyurethane materials as claimed in the parent Specification characterized in that at least one of the tertiary amino groups and at least one of the hydroxyl groups in the polyether are attached to adjacent carbon atoms. The tertiary amino groups can be introduced by firstly reacting a polyether containing at least two hydroxyl groups with epichlorhydrin or substituted epichlorhydrin in the presence of a Friedel-Crafts catalyst. The product, containing at least one end-group comprising a chlorine atom attached to a carbon adjacent to another carbon atom to which a hydroxyl group is attached is treated with an alkaline material in a solvent to convert the end group to an epoxide ring. The intermediate obtained is then reacted with an aliphatic secondary amine such dimethylamine, diethylamine, N-methylcyclohexylamine or piperidine to give the required tertiary amino group-containing polyether.  As an alternative a polyether having primary hydroxyl end groups, e.g. an oxyethylated poly-propylene oxide, is reacted with thionyl chloride and the intermediate obtained is reacted with a secondary amino compound containing at least one hydroxyl group, such as diethanolamine or N-ethylethanolamine. Examples are given of both these methods and the conversion of the products to foamed materials by reaction with a diphenylmethane diisocyanate composition, water and a silicone. Catalysts such as dibutyl tin dilaurate, stannous octoate and ferric and manganic acetylacetonates, and flame proofing agents such as tri-(b -chlorethyl) phosphate can also be included.

Abstract: 638,452. Reinforced concrete sleepers. MORK, S. A. Dec. 23, 1947, No. 34027. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 23, 1947.] [Class 104 (ii)] A reinforced concrete sleeper consists of two halves 1, 2 joined together end to end by longitudinally extending bolts 4, 5 located on both sides of the sleeper and joined in pairs to the ends of pairs of transverse bolts 6, 7 and 8, 9 which extend through pipes cast in the two parts of the sleeper.
