Title: Improvements in or relating to sizes
Inventor: MCWILLIAMS D
IPC: C09J175/04
Filed: 1969-05-02
Abstract: 1,221,639. Aqueous size. PPG INDUSTRIES Inc. 2 May, 1969 [3 May, 1968], No. 22406/69. Headings C3B and C3R. [Also in Division D1] An aqueous size suitable for application to glass fibre strands during their formation comprises an aqueous emulsion of a curable, blocked, polyurethane prepolymer, a curing agent for the prepolymer and an amino silane. The size suitably comprises 3 to 9% by weight of the blocked prepolymer and 0À2 to 1% by weight of the amino silane and may contain a non-reactive organic solvent. Preferably, the prepolymer is prepared by reacting excess of a polyisocyanate with a polyhydroxy compound, e.g. a polyether or polyester and is blocked by reaction with caprolactam. The curing agent may be more of the polyether or polyester used to form the prepolymer or a polyamine. Exemplified amino-silanes are amino-alkyl alkoxy silanes, e.g. gamma aminopropyl triethoxysilane. The size may be stabilized by adding thereto an alkoxylated amine or amide reacted with a polycarboxylic acid and then reacted with an epoxide compound. Such a compound may be one prepared by reacting 1 mole of an ethoxylated stearyl amine with 2 moles of phthalic anhydride followed by reaction of the product with an epoxy resin. A lubricant such as the pelargonic acid amide of tetraethylene pentamine may also be added to the size. The size may be applied to individual glass fibres or their emergence from an orifice in a bushing, suitably before they are grouped together to form a strand. The strand may be heat treated to remove the solvent and water and to split off the blocking agent so that the polyurethane cures. The sized strands may be chopped and blended in a tumbler mill with particles of a polyamide resin and the mixture injection moulded to form a reinforced polyamide.

Patent GB-359568-A (GB)
Title: Improved process of treating sulphide materials
IPC: C01B17/06
Filed: 1930-07-26
Abstract: In the treatment of sulphide materials with chlorinating gases free from moisture with volatilization and recovery of free sulphur and at temperatures such that the chlorides formed remain in the solid state, the finely divided solid sulphide and the gases are caused to pass through a furnace in the same direction. When by this means at least 75 per cent of the sulphide has been chlorinated conversion may be completed in a second furnace in which the gases travel in countercurrent to the solid.  The gases discharged from the first furnace may be passed through the second furnace, or unused chlorinating gases be passed there-through and then be passed into the first furnace together with the remainder of the chlorinating gases needed.  Temperatures of 300-500 DEG  C. may be used, and chlorinating media comprise chlorine with or without inert gases, sulphur being recovered as vapour below its boiling point when inert gases are present.  The process may be carried out in a rotating tube, superposed hearth, or tunnel kiln type of furnace, or in a stationary cylindrical furnace through which the charge is moved mechanically; whilst in the case of very finely divided sulphide material a jet furnace may be used.  The material treated may contain iron.

Patent GB-968746-A (GB)
Title: 19-nor-steroid-ketals and process for their manufacture
IPC: C07J1/00
Filed: 1962-06-13
Abstract: The invention comprises (1) a process for the selective protection of a 3-oxo group in a D 5(10)-3-oxo-19-nor-steroid containing at least one other oxo group by ketalization, wherein the steroid is treated with a lower aliphatic or a monocyclic-aryl-lower aliphatic monohydric or dihydric alcohol in the presence of an acidic agent; and (2) D 5(10)-3, 3-dialkoxy-19-nor-pregnenes and -androstenes, the alkoxy groups each containing at most 5 carbon atoms.  The process may be combined with other reaction steps, for example as follows:-a D 5(10)-3,17-dioxo-19-nor-androstene is converted to a D 5(10)-3, 3-dialkoxy-17-oxo-19-nor-androstene, this is reduced to the 17b -ol and the 3-keto group is released, before or after optional esterification.  The reduction may be effected with a metal hydrocarbon or halohydrocarbon compound, so that the hydrocarbon or halohydrocarbon group is simultaneously introduced into the 17-position.  Other oxo groups present in the products may also be reduced to hydroxyl groups.  Acid hydrolysis of the D 5(10)-3-ketals produces either D 5(10)- or D 4(5)-3-oxo-19-norsteroids. Examples are given.  D 5(10)-3-oxo-steroids are prepared by reduction of D 1,3,5(10)-3-alkoxy-steroids with alkali metals and liquid ammonia or an amine, the intermediate D 2,5(10)-3-alkoxy-steroids being subjected to mild acid hydrolysis.  Alternatively they may be prepared by decarboxylating D 4-3-oxo-steroid-19-acids.

Title: Cartridge-Type Tape Player.
IPC: G11B5/55
Filed: 1967-05-17
Abstract: 1,176,086. Cartridge - type tape players. TENNA CORP. 17 May, 1967 [19 Jan., 1967], No. 22847/67. Heading G5R. The tape player comprises means for receiving a loaded cartridge, a transducer supported adjacent the receiving means, means for pulling the tape past the transducer when a cartridge is inserted into the receiving means, means for selecting the track, containing the desired signals to be reproduced, by positioning the transducer to one of a plurality of discrete levels, and means for adjusting the position of the transducer with respect to the tracks by small increments to obtain optimum transducing performance. Transducer positioning for track selection.- The operator presses a selector switch 23, Fig. 1, which energizes a solenoid 120 whose armature 121 is thereupon pulled against the action of a compression spring 122. When the solenoid is de-energized the spring 122 forces a pawl 123, mounted on the armature, against one tooth of a ratchet wheel 126. The ratchet wheel forms part of an index wheel 125, Fig. 6, whose lower surface has a vertical cam 128, Fig. 6, against which is spring-urged a tab 139 an upstanding from an L-shaped arm 138; one end of the arm 138 is connected to a transducer 143, Fig. 1. A horizontal cam 127, Fig. 6, on wheel 125, moves an indicator 130, Fig. 1, at the same time, to show which track has been selected. Transducer shifting for cartridge change.- An automatic system for shifting the transducer transversely by 0À016 inches to compensate for the difference in location between the centres of tracks on four-track and eight-track tapes makes use of the fact that four-track tapes are accommodated in cartridges requiring to use a pinch roller (not shown) provided in the player mechanism, while eight-track tapes are accommodated in cartridges which cannot use the pinch roller. The pinch-roller-positioning mechanism incorporates a pin on a shaft, the shaft being turned only when the four-track cartridge is inserted. The pin thereupon engages and tilts a lever which lowers a support plate 141, Fig. 1, connected to the transducer, and thus lowers the transducer. Fine adjustment of transducer position.-To eliminate cross-talk and optimize signal quality, the operator turns a control shaft 24, Fig. 1, which is connected by a dial string 200 to a pulley 202. The pulley is fixed to an adjustment screw (not shown) which is threaded in the chassis and has a head with a horizontal slot which engages the transducer support plate 141. Alternative fine adjustment.-Instead of the string-pulley arrangement, shaft 24 may drive a shaft 206, Fig. 7, so that a pin 208 mounted thereon raises or lowers a lever 210 to raise or lower a tape guide 160 via tab 212.

Abstract: 919,294. Thermal switches; cam-operated switches. GEIGER G.m.b.H., W. June 30, 1960 [April 1, 1960]; No. 22941/60. Class 38 (5). A thermal switch moving snap-action contacts by means of a temperature-responsive deformable element has a manually-rotatable control member bearing a face-cam for adjusting the deformable member and a further, concentric, face-cam controlling a further switching device. The switch is connected in the lead of a blanket or other electrical heating appliance, and in the ON position current flows through a bimetal strip 45 in series with its heater coil 47. The bimetal operates a conventional trifurcated snap-action blade and causes contacts 32, 39 to cycle. The operating temperature is adjustable by rotating a knurled disc 21 bearing a facecam in the form of a continuous gradient which bears with variable pressure on a blade 50 and hence, through a pre-set screw 53, on the bimetal 45. At the " hot " end of this cam surface is a " very hot " position in which a cam projection closes contacts 33, 34 to short out the thermal contacts and ensure a continuous current flow to the appliance. The control disc 21 is prevented by a stop from rotating through 360 degrees and at either end of its rotation an OFF position is provided in which a cam projection depresses the adjusting blade 50 sufficiently to hold open the thermal contacts 37, 39, and a further projection opens contacts 17, 25 in the other supply lead, thus providing two-pole switching.
