Title: Improvements in circuit breakers
IPC: H01H73/50
Filed: 1965-04-21
Abstract: 1,090,933. Automatic circuit-breakers. GENERAL ELECTRIC CO. April 21, 1965 [May 28, 1964], No. 16901/65. Heading H2B. A circuit-breaker has a contact-carrying member 19 pivoted at 25 to a lever 23 which fulcrums at 37 on a latch 38 and is pivoted at 21 to a link 22. The member 19 is biased by a spring 27 and has a hook portion 20 loosely embracing the pin 21 to permit relative movement between the member 19 and lever 23 so that the spring may provide adequate contact pressure. The link 22 is connected by a pin 32 and slot 33 to an arcuate portion 30 of an operating member 29 which moves in an arcuate slot 30a formed in the casing 11. The circuitbreaker is maintained closed by the end of the link 22 abutting the side wall of the casing. Under overload conditions, an electromagnet 42 or a bi-metallic strip 46 move an armature 43 to release the end 45 of the latch 38 which releases the end of the lever 23 so that this lever and the contact-carrying member are turned anticlockwise by the spring 27 to open the contacts 17, 18. As this occurs, the end of the lever 23 strikes an extension 22a of the link 22 and moves its end from its engagement with the casing so that the operating member 29 is moved back to the " off" position enabling the various parts to reset automatically in readiness for a manual closing operation.

Abstract: 1360137 Saligenol; alkylene borates SUMITOMO CHEMICAL CO Ltd 12 April 1972 [12 April 1971] 16977/72 Headings C2B and C2C Saligenol (o-hydroxymethyl phenol) is prepared by "decomposing" a borate of formula in which R is group containing 2-10 carbon atoms which is the residue of a glycol or polyglycol of formula HO-R-OH. The decomposition referred to above may be carried out by (a) forming an alkali metal salt by treating with an alkali metal hydroxide and treating this with a mineral acid or with a compound which forms stronger chelate linkages with boric' acid than with saligenol, e.g. mannitol, or sorbitol; (b) treating it with a C 1 -C 6  alcohol to form a volatile boric ester which is distilled off; or (c) hydrolysing it with a dilute mineral and extracting the saligenol with a suitable solvent. R may be, for example, derived from ethylene glycol, and sinethylene glycol, 2,2- dimethylpropane diol, 1,3-hexylene glycol, diethylene glycol or triethylene glycol. Phenyl alkylene borates or phenylpolyalkylene borates of formula in which R is as defined above and may be prepared by reacting equimolar amount of phenol, boric acid and a glycol of formula HO-R-OH in a solvent under azeotropic dehydrating conditions; the products may be converted to compounds of Formula II above by treatment with formaldehyde or a substance yielding formaldehyde. Examples describe the preparation of borates of the latter formula in which R is -CH 2 -CH 2 -, and

Abstract: 568,908. Steam boilers. JOHNSON, J. Oct. 20, 1943, No. 17265. [Class 123 (ii)] In a steam boiler comprising, for example, an upper steam and water drum 4 and a lower water drum 5 with two banks 1, 2 of interconnecting tubes, one bank on each side of the combustion Chamber 6, and in which there are two parallel flue gas passes 15, 16 controlled by a damper 35 and locating a reheater 21 and superheater 24 respectively, a by-pass 26 having a damper 28 is provided in parallel with the passes 15, 16, the said two passes and by-pass all leading to a common flue 32 extending upwardly above the boiler casing. An economiser 33 is preferably located in the flue 32 and an air heater 34 in a continuation of the latter, with a second by-pass 58, controlled by a damper 59, leading from the by-pass 26 to the flue at a position above said economiser. The arrangement is such that the degrees of superheating and reheating may be raised or lowered simultaneously by operation of the damper 28, to permit the passage of more or less of the flue gases through the by-pass 26, and the degree of reheating may be raised or lowered relatively to the degree of superheating by operating the damper 35 which controls the relative gas flows through the two passes 15, 16 ; moreover, during starting-up the boiler, and with the dampers 28, 35 closed, the damper 59 may be opened to prevent overheating of the reheater and economiser. The gas passes 15, 16 are bounded by the inner side walls 7, 7 of the boiler and walls 17, 18 respectively above the steam drum, the reheater 21 extending from the front to the back of the boiler and the superheater 24 stopping short of the back with its tubes forming a partition wall 25 defining the inner side of the by-pass 26.

A detent pin 5 is fixed to a limb 3 of the lever 4 to lock the minute wheel 11 when the pawl 7 is disengaged therefrom. In operation the actuating arm 8 of the pawl 7 drives a wheel 11 until the movement is stopped by the locking arm 9. Reverse rotation of the wheel 1 may be prevented by a pawl 18. Snail cam 13 may be loose on the seconds spindle and engaging a hole 17 in the cam. When the cam follower 12 moves over the point of the cam it causes the latter to rotate relatively to the shaft 14, the cam then remaining stationary until the pin 16 again engages the side of the hole 17. The snail cam may be replaced by an eccentric. The minute wheel 11 may be connected to its shaft by a friction coupling comprising discs of cork, fibre or rubber. The device may be applied to an electric clock, the pawl-carrying lever then having secured to it an armature of semicircular shape acted upon by an electromagnet receiving time impulses.

The ports 12.. 15 are controlled by a sleeve valve 2 which, as the charge is ignited by a spark plug 27 in the combustion chamber, is moved upwards so as to close the port 15 and open ports 171 connecting the combustion chamber to the cylinder. As the sleeve valve returns, it again closes the port 17<1>, but exhaust of the combustion chamber is obtained by a downward movement of the combustion chamber, which thus also acts as a valve. In a Diesel engine, fuel is injected into the combustion chamber. In another form, the combustion chamber is fixed, and its ports are controlled by the sleeve valve and by another short sleeve operating in the top of the chamber. In a further modification, the combustion chamber is placed at the side of the cylinder, its communication with the cylinder being controlled by the sleeve valve, a poppet valve separating it from the transfer conduit. Valve gear.-The sleeve valve 2 is actuated by a cam 22, and the combustion chamber 16 by a cam 23, push-rod 20, and rocker 19.
