Title: Improvements in thermostatically controlled electrical switching devices for refrigerators
IPC: F25B49/02
Filed: 1960-08-22
Abstract: 935,952. Thermal switches. BRITISH THERMOSTAT CO. Ltd. (Soc. Francaise des Thermostats). Aug. 18, 1961 [Aug. 22, 1960], No. 28964/60. Class 38 (5). A refrigerator switch is provided with a defrost button coaxial with the normal range knob but operable independently thereof to apply an additional spring loading to the thermal element so as to cause defrosting to take place. The switch disclosed in Specification 867,245 is modified by the provision of a push rod 2 and button 3 extending through the range knob 4. The end of rod 2 engages an extension 6 to the switch operating lever 19 which thus opens the contacts when the button 3 is depressed. A spring-loaded detent 8, 9, 10 holds the button in its depressed condition. Before the switch contacts are reclosed the thermal element must overcome not only the normal range spring bias on the lever 19 but also the detent 8, 9, 10. The operating temperature of the switch is thus raised causing defrosting to take place. The action of the spring 10 and therefore the defrosting temperature is variable by means of a screw 12. In a modification (Fig. 2, not shown), the action of the spring 10 varies with the setting of the range knob so that whatever the normal working temperature the defrost temperature is the same.

Abstract: 1312667 Retractive switches BUCHANAN ELECTRICAL PRODUCTS CORP 15 June 1970 [13 June 1969] 28981/70 Heading H1N An electric limit switch comprises a housing 12 containing an actuating member 36, terminal blocks 26, a switch 22, 24 having terminals in the form of contact projections 23 engaging terminal block 26 and means removable from housing 12 and separate from cover 30 for supporting switches 22, 24 in housing 12. As shown, these are two switches 22, 24 and they are supported in housing 12 partly by insulating plate 28 and partly by terminal blocks 26. Contact projections 23 fit through slots 72 in plate 28 and plug into sockets formed in terminal blocks 26 by the terminals 74, Fig. 4 (not shown), and spring metal clips 82, Fig. 4. Switches 22, 24 are also supported by projections 66, 68, 70 on plate 28 which also serves as a cover for the terminals and has a ridge 69 around its edges to lengthen creepage distances. Gasket 32 makes the cover oil tight. The switches are actuated by moving roller 20 which rotates arm 18 which rotates shaft 16 which rotates cams 40, 42 which depresses plunger 50 which depresses actuating member 36, projections 37, 39 on which depress the buttons 25 on switches 22, 24. Projections 37, 39 are eccentric and if rotated by means of the screw-driver slot in their ends adjust the amount of pre-travel of the actuating mechanism. Arm 18 is returned to its original position on removal of the operating zone by a spring 56 which bears on member 54 having a flat lower surface which bears on a cut-away portion having a flat of shaft 16. Plunger 50 and member 36 are returned to their original positions by retractive springs in switches 22, 24. The switch can be set to be actuated by rotating arm 18 in one direction, in the other direction or either way by removing flexible cover 44, depressing member 46 which frees latch 47 from notches 48 and sliding shaft 16 along so that cam 40 or cam 42 or both actuate plunger 50, then latched in position by latch 47. Turret 14 can be rotated by means of worm 58 and thread 59. In three further embodiments roller 20, arm 18, shaft 16 and cams 40, 42 are replaced by a horizontal retractive plunger 102, Fig. 5 (not shown), by a vertical retractive plunger 136, Fig. 6 (not shown), or by a retractive joy stick 166, Fig. 7 (not shown). Roller 20 can be replaced by a roller 200, Fig. 8 (not shown), comprising a nylon core, if required surrounded by a metal ring.

Abstract: 1325627 Equilibration of organosiloxanes WACKER-CHEMIE GmbH 21 June 1971 [23 June 1970] 29004/71 Heading C3T In processes for the manufacture of organopolysiloxanes by equilibration of organosiloxanes containing triorganosiloxane units with other siloxane compounds in the presence of catalysts which are solid under the reaction conditions, a stream of a gas that is inert under the reaction conditions is passed through the catalyst bed at a rate of 0À05-1À5 litres per hour per litre of reaction vessel contents (at 20 C. and ambient pressure). The gas appears to prevent the catalyst from absorbing water produced in the equilibration reaction and so becoming inert. Suitable gases are air or, better, nitrogen, argon, hydrogen and CO 2 . The organosiloxane to be equilibrated may be a mixture of compounds R 3 SiO(SiR 2 O) m SiR 3  with compounds HO(SiR 2 O) n H and/or (SiR 2 O) p , or mixed hydrolysates of silanes R 2 SiX 2  and R 3 SiX, where each R is an optionally substituted hydrocarbon radical, m is 0 or an integer, n is an integer of at least 2, and p is an integer of at least 3; units other than R 2 SiO, RHSiO and R 3 SiO 0À5  may be present up to 10 mol. per cent. Suitable catalysts include fuller's earth, kaolin, active charcoal, molecular sieve aluminium silicates, sulphonated coal and sulphonated styrene-divinylbenzene copolymer. In Example 1 166À8 c.c./hr. of polydimethylsiloxane diol and 6À8 c.c./hr. of Me 3 SiOSiMe 3  are passed with 1600 c.c./hr. of N 3  over 1800 c.c. of granulated fuller's earth at 105-115 C. In Example 2 75 c.c./hr. of a similar siloxane mixture with 25 c.c./hr. of toluene is passed with 650 c.c./hr. of N 2  over the same catalyst bed. The products are trimethylsilyl - terminated polydimethylsiloxanes of 100 and 750 cS./25 C. viscosity.

R preferably contains 1-20 carbon atoms. A cross-linking monomer such as diethylene glycol diacrylate, trimethylol propane triacrylate and methacrylate, and 1,4-butylene glycol diacrylate may also be present. The viscosity of the monomer composition may be adjusted by addition of an organic polymer such as methyl cellulose, ethyl hydroxyethyl cellulose, cellulose acetate, polybutadiene, polychlorobutadiene, polyvinylace. tate, poly(vinylacetate/2-ethyl hexyl acrylate), poly(vinylacetate/vinylchloride) and poly(ethylene/vinyl acetate). The backing material may be, for example paper, wood, glass, tile, film, polyurethanes, polyesters, P.V.C. and polyvinylidene chloride. High energy electrons is the preferred radiation used.

Title: Processes for the manufacture of steroid derivatives and new steroid derivatives

Abstract: The invention comprises 16a -trihalomethyl-20-keto compounds of the pregnane series and 16a -methyl-pregnan-3a -ol-11, 20-dione, and a process for the preparation of 16a -trihalomethyl-20-keto compounds of the pregnane series by subjecting a 16-dehydro-20-keto compound of the pregnane series to an addition reaction with haloform with the optional further step of hydrogenating the 16a -trihalomethyl compound in the presence of a dehalogenation catalyst such as Raney nickel, to form the corresponding 16a -methyl compound.  The reactants used in the above process may contain substituents in other positions of the molecule such as free or functionally converted hydroxy groups, or double bonds.  If a free 3-keto group is desired in the end product it must be protected during the reaction with haloform, e.g. by conversion to an ethylene ketal group, or a reactant may be used containing a 3-hydroxy group which may subsequently be oxidised to a 3-keto group.  In the examples: (1) 16a -tribromomethyl-\se5-pregnenolone is prepared and is then hydrogenated to form 16a -methylpregnenolone and then oxidised to 16a -methylprogesterone; (2) 5 : 16-pregnadiene3b -ol-20-one in treated with chloroform to form the corresponding 16a -trichloromethyl compound and is then treated with t-butanol to form 16a -trichloromethyl-\se5-pregnene-3b -t-butoxy-20-one; (3) 16a -tribromomethyl-pregnon-3a -ol-11, 20 - dione is prepared and is hydrogenated to form 16a -methylpregnan-3a -ol-11, 20-dione.

Abstract: 626,078. Operating clutches. ELLIOT, J. M. Oct. 3, 1946, No. 29512. [Class 80 (ii)] [Also in Group XXXI] Auxiliary manual control of the clutch of an agricultural tractor comprises a hand lever 4 pivoted at 5 to a baseplate 1 and connected by levers 7, 10 to the clutch operating mechanism 8. A spring 3, the effect of which is more powerful than that of the clutch springs is secured at one end to a lug 2 on the baseplate 1 and at the other end to the lever 4. In the clutch engaged position, a pin 11 on the lever 4 engages a spring pressed catch 12. On release of the catch 12, clutch disengagement is effected by the forward movement of the lever 4 under the action of the spring 3. The forward movement of lever 4 is limited by the engagement of a roller 16 on the lever 4 with the underside of the baseplate 1. Normally the handle is retained by its catch 12, so that with the levers 7, 10 slack, the foot clutch pedal 17 may be independently operated.
