Title: Improvements in or relating to bituminous compositions
Filed: 1948-03-12
Abstract: A bituminous composition particularly for use in the preparation of pavements, roads, floors, and rust preventives comprises a natural or artificial bituminous material, a mineral aggregate and, in order to increase the wetting of the aggregate by the bituminous material, sulphur and an oleophilic aliphatic monoamine and/or a salt thereof, the sulphur and amine each amounting to 0.1 to 2.0 per cent of the bituminous material.  The amine may be one having 12 to 24, particularly 12 to 18, carbon atoms, and is preferably one wherein the amino group is attached to a terminal carbon atom, e.g. mono-octadecylamine, although it may be attached to a carbon atom at a position other than the terminal or to a branched chain.  The sulphur must be in elemental form.  The aggregate may be acid, basic or neutral in character. The sulphur and amine may be incorporated in the bitumen by stirring or in solution or dispersion, with heating if necessary, or may be applied to the aggregate.  An organic lypophilic acid, e.g. naphthenic acids, fatty acids such as stearic acid, wool-fat acids, acids obtained by the oxidation of paraffin wax, higher alkyl diacids such as dialkyl succinic acids, phthalic acid, and oil-soluble sulphonic acids, may also be added.  The Specification as open to inspection under Sect. 91 describes also the application of the invention to the manufacture of paints and in connection with lubricating oils, electrical oils, and spray oils. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to control systems for direct current electric motors
IPC: B60L15/12
Filed: 1952-03-26
Abstract: 706,456. Control of D.C. Motors. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 26, 1952 [March 30, 1951], No. 7730/52. Class 38(3) Relates to a control system similar to that described in Specification 706,455 but the claims refer to means for checking the sequential advance of the motor accelerating steps in response to the magnitude of the motor current and to a voltage induced in a field winding of the motor. Reference is also made to means for discontinuing dynamic braking operation when the braking-current falls. to a low value. In a modification of the arrangement shown in the Specification referred to above, the coil 25 of the current-limit relay LR<SP>1</SP> is connected directly across the series field winding 6, an increment of motor current causing a transient voltage increase across terminals 17, 18, due to the inductance of the field winding. The winding 25 therefore receives a steady-state voltage as well as a transient voltage.

Title: Method of molding a polyurethane and product therefrom
IPC: C08G18/65
Filed: 1959-03-10
Abstract: <PICT:0914825/IV(a)/1> <PICT:0914825/IV(a)/2> A method of making shaped bodies of a solidified cross-linked polyurethane prepared by reacting (a) an organic compound having two active hydrogen atoms in the molecule, as determined by a positive Zerewitinoff test, (b) a cross-linking agent differing from the said organic compound and having active terminal hydrogen atoms and (c) an organic polyisocyanate present in a molecular amount that exceeds the sum of the molecular amounts of the first mentioned organic compound and the cross-linking agent, so that the ratio of isocyanate groups to active hydrogen atoms is greater than one, the reaction being continued until all possible chemical interaction between the three ingredients has taken place so as to form a solidified polymer consisting essentially of a linear polyurethane cross-linked to another linear polyurethane to the maximum possible extent, comprises heating the solidified polymer as sole reactive ingredient to an elevated temperature sufficient to make it flowable, and shaping the flowable polyurethane to the desired form.  The cycle of heating, setting and reheating can be followed at most two or three times, usually twice, after which the method is not feasible because of degradation of the polymer.  Polyesters, polyesteramides, alkylene glycols, polyoxyalkylene glycols and their polyisocyanate modified products having free hydroxyl and/or carboxyl groups are suitable starting compounds.  Preferred polyisocyanates are diphenylmethane -4,41-diisocyanate and 3,31-dimethyldiphenylmethane -4,41-diisocyanate, though others are listed.  1,4-Butanediol, ethylene, propylene, butylene, diethylene and triethylene glycols and glycerol are suitable cross-linking agents.  As catalysts there are specified 1,4-butane diol, N-methyl-morpholine, dimethyl ethanolamine, triethylamine, N,N-diethyl or dimethyl cyclohexylamine, and cobalt naphthenate.  The solidified polymer can be converted to a granular or pelletized form, and may be heated and shaped in plastic moulding machinery, for example to effect injection moulding or extrusion into pipes, cylinders, filaments or threads.  Threads, filaments and fibres can be produced from pellets of polyurethane using an extrusion machine (Fig. 2) in which an elongated member 13 with a spiral or thread 13a is mounted for rotation.  The end of the barrel is heated by bands 16, 17 and 18 at 320 DEG , 310 DEG  and 300 DEG F.  As the pellets are heated they become sufficiently fluid to pass through a screen plate 19 and are then extruded through a spinnerette 21 having a plurality of holes 22 arranged as shown in Fig. 3.

Filed: 1970-02-23
Abstract: 1291365 Sterile packages G W PONCY 23 Feb 1970 8574/70 Heading B8C An open ended transparent sheath into which a thermometer or probe is to be inserted has a sterile outer surface enclosed by a cover which may be torn from the sheath so that the latter, containing the thermometer or probe, may be inserted into a body cavity without risk of infecting the patient. As illustrated, the packaged sheath comprises inner transparent thermoplastics layers 12 and 14, and outer layers 10 and 11 of paper or cloth having coatings 10a and 11a of heat sealable material. The layers are connected along a heat seal line 16 which defines the shape of the sheath. When the outer layers are pulled apart from the closed end of the sheath, the package parts at the heat seal line 16 so that the sheath, formed by those parts of the layers 12 and 14 lying within the seal line, is exposed. The outer waste portions of the layers 12 and 14 are sealed at their ends to the layers 10 and 11 and are therefore torn away with them. The outer surfaces of the layers 12 and 14, and the inner surfaces of the layers 10 and 11 are sterilized using ultra-violet light either before or after assembly of the package. Packages are formed by superimposing strips of the various materials, sealing them along the edges of the strips, forming the heat seals 16 so that the sheaths extend across the strips, and severing the strips to form the individual packages. The strips forming the layers 10 and 12 are wider than the strips forming the layers 11 and 14 so that each package has a tab at each end to facilitate tearing. The layers 12 and 14, and the coatings 10a and 11a may be of ethylene vinyl acetate. Alternatively, the layers 12 and 14 may be of ethylene vinyl acetate and the coatings 10a and 11a of pressure sensitive adhesive.
