Patent GB-984708-A (GB)
Title: Polycondensates of diisocyanatoalkanes
IPC: C08G18/02
Filed: 1963-06-07
Abstract: Thermosetting polymers are obtained by heating an a ,o -diisocyanatoalkane in the absence of water in an inert atmosphere and in the presence of a cyclic trimer of a phosphinoborane of formula <FORM:0984708/C3/1> where R is an alkyl group, and X and X1 are hydrogen or halogen atoms.  From 1 to 5% of the trimer, based on the weight of the diisocyanatoalkane, may be used, and the mixture may be heated to 150 DEG  to 250 DEG  C.; a diluent may or may not be present. Carbon dioxide is evolved but the polymer contains a part of the oxygen initially present in the isocyanate groups.  In examples, polymers are obtained by heating 1,6-diisocyanatohexane in the presence of the trimer of dimethylphosphinoborane.

IPC: G05D7/01
Filed: 1961-06-23
Abstract: 989,224. Valves. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 4, 1962 [June 23, 1961], No. 22915/61. Heading F2V. A valve for gas flow comprises a body 1 and a diaphragm 2 defining an interspace 5, inlet and outlet ports 6, 7 in the body and communicating with the interspace, a restrictor 15 replaceably housed in one of the ports and means for deflecting the diaphragm into contact with the restrictor for effecting variable impedance to gas flow therethrough. The means for deflecting the diaphragm consists of a worm gear 18, 19 and a screwed spindle 16 with a pressure pad 17 while the restrictor consists of replaceable polyethylene tubing 15 having a bore of the order of 0.03 inch diameter. The diaphragm 2 and an annulus 13 obturating the outlet port 7 are also of polyethylene. The valve is stated to give accurate control of flow in the range 1 to 20 Ál/hour and to be suitable for use with mass spectrometers.

Title: Tape splicing mechanism
Inventor: WALLENS ANTHONY WALTER
IPC: H04L13/06
Filed: 1957-07-19
Abstract: 830,987. Feeding webs. CREED & CO. Ltd. July 19, 1957, No. 22923/57. Class 100(1) A tape splicing mechanism comprises a pivoted support 4 for two reels 2 and 6 of tapes 1 and 7, a spring-urged sensing roller 32 engaging the periphery of the reel from which tape 1 is being fed, a stud 33 for closing electrical contacts 34 when the tape is substantially exhausted, a rotatably mounted lever 23 having a clamp 14 for engaging a co-operating clamp 13 when the lever 23 is rocked. A solenoid 26 is energized on closure of the contacts 34 upon substantial exhaustion of the tape 1, thereby moving the armature of the solenoid to rotate the lever 23 to clamp, between the clamps 13, 14, the leading end of a tape 7 from a replacement reel 6, to the expiring end of the tape 1. A knife 18, co-operating with a block 22, is actuated to cut the expiring end of the tape 1 upon depression of the lever 23. The clamped portions of the tapes 1 and 7 are heated by the clamp 13, such that heat-sensitive adhesive on the underside of the tape 7 splices the tapes. A thermally operated relay, not shown, de-energizes the solenoid 26 after a predetermined period, thus releasing the tape 7. In a modification, Fig. 5 (not shown), the roller 32 may be replaced by a pin sensing the end of tape being unwound.

Abstract: 1,113,724. Latches. EREBUS MANUFACTURING CO. Ltd. 24 May, 1966 [29 May. 1965], No. 22930/65. Heading E2A. A latch comprises a light spring 24 which biases the bolt to an extended position, a spring 33 which acts on one end of a bar 23 in contact with the flat face of a follower 19 to return the follower and the handle engaged with the follower to the bolt extended position the bar 23 extends across the latch casing and adjacent the other end pivotally engages an abutment on the casing. Rotating the handle causes a horn 18 of the follower to engage an end 17 of the latch to retract the latch and compress both springs 24 and 23 which restore the bolt, follower and handle to their original positions. The spring 24 which abuts the bolt at one end abuts a member 25 slidable in the latch casing or a fixed abutment at the other end. The base of the box shaped latch casing and the cover plate have aligned holes 37 for securing the latch to a finger plate or the like.

Title: Method of and apparatus for spinning yarn
IPC: D01H/
Filed: 1972-05-16
Abstract: 1415502 Ring spinning machines PLATT SAGO LOWELL LTD 9 May 1973 [16 May 1972] 22950/72 Heading DID In a method of spinning yarn using a ring and traveller to form the yarn into a package on a spindle with the yarn forming a descending coil around the spindle 3a between a crown at the top of the spindle and the traveller, the descending coil of yarn is so intercepted with a conical or frusto-conical projection 10 that sufficient tubes are maintained in the coil in the spindle throughout the package build to prevent transmission of the full tension of the yarn being wound onto the package to the yarn being delivered to the spindle in the zone above the crown. The spindle 3a comprises a crown at its upper end formed with flutes 8, a lower portion 4 for receiving a core in which the yarn is wound, an upper portion 6 of smaller diameter than the portion 4, and one or more projections 10 to intercept the yarn coil on the spindle. The upper and lower portions 6 and 4 are connected by a diverging shoulder 9 presenting a frusto-conical surface. The projections 10 are positioned at the same axial location and equi-spaced around the spindle. They may be provided on the upper portion 6 or on the shoulder 9. The projections 10 are preferably formed by conical studs screwed into receiving holes in the spindle. The upper and lower portions 6 and 4 may be integrally formed or the upper portion 6 may be screwed into a receiving hole 14 in the lower portion 4. At the start of the package build the yarn slips easily over the studs 10 on its passage to the traveller. As the package build progresses, the ring moves up and the tension in the yarn increases causing it to engage one of the studs 10, the number of turns in the coil on the spindle then increases which reduces the tension transmitted to the yarn approaching the spindle in the zone above the crown.

Title: Apparatus for manufacturing lithopone
IPC: C09C1/06
Filed: 1921-08-30
Abstract: 189,525. Fairweather, H. G. C., (New Jersey Zinc Co.). Aug. 30, 1921. Pigments.-An apparatus for uniformly heating or muffling lithopone comprises a vertically disposed and externally heated retort, or bank of retorts, through which the lithopone is passed under gravity. The retort 15, Fig. 2, preferably of iron, is 25-30 feet long and not greater than 12 inches in diameter, and a section of it may taper slightly upwards. A flue 16, for hot gases, surrounds the retort. The furnace walls have an intermediate layer of heat-resisting material 19. Hot gases from the combustion chamber 27 enter the flue 16 by a passage 34 and a heat equalizing chamber, in which are slabs 37 of refractory material having considerable heat capacity. A single combustion chamber may provide heat for several independent retorts. The muffled product is automatically discharged by means of a star-wheel 43, Fig. 10, which is periodically turned through 90‹. The operating means comprises a belt or chain 46, driven at uniform speed and carrying a dog 50 engaging the arms 52 on the shaft of the star-wheel 43. The muffled product is discharged into a tub 54, filled with cooling liquid, for example cold water. The discharge pipe 56 carries a trough 57 which is filled with liquid; and a pipe 58, suspended by cables 59, carries an inverted U-shaped member at its upper end, so that when the pipe 58 is lowered, air-tight sealing is effected, whilst the pipe may be raised in order to change the tubs. The lithopone is muffled in the form of small lumps containing as much as 10 per cent of moisture, and passes down the retort in 5-10 hours, being heated to a temperature of 550- 800‹ C. and surrounded by a non-oxidizing atmosphere mainly composed of water vapour. The gases evolved escape at the top of the retort.
