A temperature sensor comprises a metal housing having an externally threaded plug with a central longitudinal blind bore and a thermistor clamped in conductive contact with the bottom of the bore, which is located near the end of the plug, between two contact pieces one of which is in the form of a disc fixed at the bottom of the bore and the other is in the form of a sleeve guided within the bore in an insulated manner and secured to a braided lead by a pinched connection. As shown, Fig. 1, a temperature sensor 1 for the petrol injection system of an internal combustion engine comprises a threaded plug 3 with a hexagonal flange 2 and a blind bore 5 containing a negative temperature coefficient thermistor element 10 clamped between two silver or silver coated contact members 12, 14, both of which have annular beads 12<SP>1</SP>, 14<SP>1</SP> on their contact faces to centre element 10. The upper contact member 14 is crimped to the end of a braid conductor 15 and is pressed against the element 10 by a spring 15 acting via an insulating disc 16 which serves to centre the contact member 14 within the bore 5. The upper end of the spring 11 presses against a copper disc 20 crimped to the braid conductor 15 at such a position that the conductor is S- shaped between the disc 20 and the contact member 14. The disc 20 and the spring 11 are insulated from the body by an insulating sleeve 21, and a reinforcing sleeve 25 secured to the top of the body is crimped over the insulation 18 of braid conductor 15.
Patent GB-743288-A (GB)
Title: Improved dynamometer
Inventor: TELL SVEN
IPC: G01L1/04
Filed: 1953-07-20
Abstract: 743,288. Dynamometers. AKTIEBOLAGET PIAB. July 20, 1953. No. 20113/53. Class 106 (2). [Also in Group XVIII] A dynamometer for measuring tensions comprises a casing 1, a drawrod 7 displaceable within the casing against the action of spring elements 11 in the form of annular conical discs surrounding the drawrod, and a measuring scale in the form of a drum 19 that is threaded on the draw-rod 7 at 17, and which is rotated when the drawrod 7 is axially displaced in the casing. The drum 19 is visible through a window 20 in the casing 1, the window 20 having an index mark. The drum 19 is rotated against a spring 24. To deal with any sudden cutting off of the tension applied to the dynamometer, the shock on the draw-rod 7 produced by the springs 11 is absorbed by a damper spring 16. At the same time, however, the scale drum 19 is forced back with the draw-rod since the spring 24 is unable to counteract this shock, and the upper end 26 of the spring 24, slides upwards in a slot 29. After the shock has ceased the spring 24 rotates the scale drum 19 so that the latter is screwed down on the part 17 of the draw-rod until it lies up against a ball-bearing 27.

Title: Improved process for preparing alpha olefins of high vinyl olefin content
IPC: C07C67/00
Filed: 1963-05-22
Abstract: Ethylene is catalytically polymerized in the presence of an alkyl aluminium compound and the polymers are separated from the trialkyl aluminium by adding sufficient alkoxide-forming reagent to convert at least one-third of the alkyl groups to alkoxide in the aluminium compound followed by distillation.  The alkoxide may be formed by reaction with oxygen, preferably concentrated to avoid separation of inert gas, or by addition of a polyalkoxide aluminium compound.  In a preferred embodiment, this is a recycle stream containing alkyl aluminium dialkoxide and/or aluminium trialkoxide in sufficient amount to convert the trialkyl aluminium at least to dialkyl aluminium alkoxide; after distilling off the polymers the residue is then oxidized with oxygen or air at up to 100 DEG  C. to form the recyle stream, any excess being hydrolysed to recover alcohols, hydrocarbons and an inorganic aluminium compound.  Polymerization is effected at 180-200 DEG  C. and 2500-4000 p.s.i.g. using 1-3% by wt. of trialkyl aluminium based on ethylene reacted.ALSO:In the separation of trialkyl aluminium compound from ethylene polymers the mixture is treated with sufficient polyalkoxide aluminium compound, i.e. alkyl aluminium dialkoxide and/or aluminium trialkoxide to form dialkyl aluminium alkoxide and/or alkyl aluminium dialkoxide with the trialkyl aluminium.  After separating the ethylene polymer by distillation the aluminium compounds are oxidized with oxygen or air to form di- or tri-alkoxides which are partly recycled and the excess hydrolyzed to form alcohols.

Abstract: 1,081,401. Yarn-forwarding rollers. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 6, 1965 [May 20, 1964], No. 20718/64. Heading B5B. Yarn-forwarding apparatus contains a driven roll 7, the outside end section of which has a low-friction surface 10 and the remainder has a highfriction surface 9. Surface 10 may be polished and surface 9 matt. In stringing-up the apparatus, yarn 11 is caused to make wraps, sufficient in number to prevent slip, round the feed roll 1 and idler separator roll 2 with skewed axes, is wrapped once round snubbing-pin 3 and is then passed round guides 4 and 5, and hence to draw roll 7 and idler separator roll 8, round which it is caused to make a number of wraps. Roll 7 is driven with peripheral speed at least 3 times that of roll 1. Guide 5 is initially so positioned that the yarn is in contact with the low-friction surface 10. As there is considerable slip, the free end 12 of the yarn has a reduced tendency to become wrapped round roll 7. When the requisite number of wraps have been made guide 5 is moved to the alternative position, and the yarn under the action of guide 4, moves on to the high-friction surface 9, whereon it is accelerated to the peripheral speed of the roll. The yarn is taken off roll 7 via low-friction surface 10, thus reducing the possibility of a back-wrap. The apparatus may comprise two driven rolls, with corresponding high and low friction sections.
