Title: Electric immersion heater
IPC: H05B3/50
Filed: 1968-10-31
Abstract: 1,208,967. Electric immersion heaters. ELEVATOR EQUIPMENT CO. 31 Oct., 2968 [4 March 1968], No. 51763/68. Heading H5H. In order that the temperature of the heated liquid may be maintained constant and that the temperature of the housing 15 of an electric immersion heater may be kept below an excessive value, the housing 15 contains a heating element 78 at one end and a thermostat 40 at the opposite end, the thermostat being mounted on a wall of the housing so that it senses the resultant temperature of liquid engaging the wall and the part of the housing containing the heating element 78. The housing 15 is made of aluminium and has a finned part containing the heating element 78 and a cover-plate 22 carrying the thermostat 40. A fluid-tight gasket 26 between the cover 20 and finned part of the housing provides a degree of thermal insulation between the thermostat 40 and the finned part of the housing so that the thermostat will only respond to the temperature of the finned part when this temperature is a few degrees greater than that of the liquid in contact with the cover-plate 20 which would actuate the thermostat. The thermostat 40 includes a bimetallic switch and its operating temperature is adjustable by limited rotation of a stud 56. The immersion heater is mounted in a hole in the wall of a reservoir 10, gaskets 34, 36 providing a fluid-tight seal. The heater is designed for heating oil.

Title: Device for automatically preparing cops for automatic spoolers
IPC: B65H67/08
Filed: 1968-11-04
Abstract: 1,245,770. Preparing cops. FR. METTLERS SOHNE MASCHINENFABRIK A.G. 4 Nov., 1968 [9 Nov., 1967], No. 52126/68. Heading D1J. A device for automatically preparing caps for delivery to an automatic spooler has two rollers 3, driven in the same direction by a motor 6, which support between them successive cops 1 so that the latter are rotated in a yarn unwinding direction. A suction duct 22 with its duct inlet 23 positioned between rollers 3 loosens the yarn end 16a from rear end 18 of cop former 17 and so the underwinding 19 is unwound. Below cop head 20 a phototransducer 26 is mounted on duct side wall 24 and light shines on it from a lamp 28 on side wall 27 through slots in these walls. The unwound yarn 19' is held in a confined area by means of yarn catcher 24. This hanging yarn cuts off the light from lamp 28 to transducer 26 which causes the contacts 76 of a relay 75 to close thus energising a cam motor 60 with a shaft 59. Cam 56 on shaft 59 operates switch 48 which operates electromagnet 32 which causes knife 31 to move towards stationary knife 29 to cut off the unwound yarn underwinding 19'. Cam 57 operates switch 49 to first energise electromagnet 41 of pusher 40 which moves cop 1 backwards a distance equal to a part of the length of cop-former head 20 on rollers 3; and then through pole changer winding 67 to cause the rollers 3 to change their direction of rotation so that yarn end 16b is wound about head 20. Cam 58 operates switch 50 for turning on motor 8 which causes arm 9 to turn from its rest position (fig. 1), through one revolution to knock off cop 1 from rollers 3 onto an outlet shute 10. Switch 50 also energises electromagnet 14 which causes stop 11 to move to 11' position so that one cop at a time rolls down shute 2 onto rollers 3.

Title: Polyurethanes
IPC: C08G12/42
Filed: 1964-06-01
Abstract: A polyurethane is prepared by reacting a polyisocyanate with a polyarylaminopolyether which is obtained by reacting an organic cylic oxide with the reaction product of an arylamine and an aldehyde and which has the general formula <FORM:1073664/C3/1> wherein Ar is the residue of the arylamine, R1 of the aldehyde and R of the organic oxide, n being 1-20 and X being a whole number (see Specification 1,073,663).  The preferred polyarylaminopolyethers are prepared from aniline, formaldehyde and propylene oxide, but many other suitable amines, aromatic and aliphatic aldehydes, and aromatic and aliphatic cyclic oxides are listed.  The toluene diisocyanates and 3:31-bitolylene-4:41-diisocyanate are the preferred polyisocyanates; others suitable are ethylene, tetramethylene, hexamethylene, cyclohexene-1:2, m- and p-phenylene, 1:5-naphthalene, p,p1-methylene diphenyl, 3:31-dichloro - 4:41 biphenylene, 4 - chloro - 1:3-phenylene, and thiodipropyl diisocyanates and triphenylmethane triisocyanate, and calcium diisocyanate.  An excess of 15-35% of isocyanate over hydroxy groups is preferably used, giving a "prepolymer".  In the preparation of foams a siloxane surfactant, e.g. a siloxaneoxyalkylene block copolymer, may be used, e.g. in amounts of 0.25-2 wt. per cent of the total. Foaming may be achieved by physical means, e.g. using CHFCl2, CHCl3, CFCl3, CCl4, CH2Cl2, CHFCl, CH3.CH2.CHF2, CH3.CF2.CH3, CCl3.CF2.CH3, C2Cl4Br2, CF2Br2, C2F4Cl2, C2F3Cl3, C2H5Cl, pentane, hexane, heptane, cylohexene, and diethyl ether, amounting, e.g. to 10-60% of the total weight, or by chemical means e.g. using water or a dibasic acid e.g. succinic acid. A basic foaming catalyst is usually employed e.g. 0.5-3 wt. per cent of methyl piperidine, tribenzylamine, pyridine, N:N:N1:N1 - tetramethylbutanediamine, triethylamine, N-methylmorpholine, dimethylethanolamine and N:N1-bis(2-hydroxypropyl)-2-methylpiperazine. Suitable polyols for reaction with the prepolymer include alkoxylated polyols including glycerol, pentaerythritol and a list of sugars and similar alcohols. Conventional dyes, fillers, softeners, plasticizers, wetting agents etc. may be added.  In examples propoxylated aniline-formaldehyde products are converted into prepolymers with toluene diisocyanate, and foams are prepared by a two-stage reaction of these with futher polyarylaminopolyethers. In Examples IV and V foams are prepared by reaction of the propoxylated aniline-formaldehyde with a prepolymer from sorbitol and toluene diisocyanate or with a polyisocyanate from phosgene and an aniline-formaldehyde product-the latter a "one-shot" process.

Abstract: 1,143,450. Burglar alarms. BROCKS ALARMS Ltd. 4 Dec., 1967 [5 Dec., 1966], No. 54338/66. Heading G4N. [Also in Division H1] A pair of reed contact units are magnetically in series with a movable magnet in the operating position thereof. A burglar alarm is actuated when either of two magnetic reed contact devices 4, 5 mounted in a door post are opened due to removal of an operating magnet 8 carried by door 7. If a magnet 9 is brought adjacent the contact devices in order to nullify the alarm and is poled as shown it will either tend to keep contact device 4 closed and open contact device 5 or if it is less powerful than magnet 8 its effect on device 5 will be insufficient to open it. However, should the door be opened in either direction one or both contact devices in succession will be opened momentarily actuating the alarm. With the arrangement shown, once the alarm has been set, closure of the door will cause the alarm circuit to be closed, opened and closed again. Thus some circuitry must be provided to prevent the alarm responding to this double switching action. To obviate this a magnetic shunt may be placed between the contact devices. This ensures that the contact device which closes, opens and then recloses does so before the other contact device closes to prime the alarm circuit. The contact devices may be in separate circuits instead of being connected in series as shown.
