Title: Cooking temperature control apparatus
Inventor: CLAPP DANIEL ELLIOTT
IPC: H05B1/02
Filed: 1959-08-10
Abstract: 860,339. Thermal switches. PROCTOR ELECTRIC CO. Aug. 10, 1959, No. 27219/59. Class 38 (5). [Also in Group XXXV] A detector unit for use with an automatic temperature - control system for a cooking vessel comprises a snapaction switch having contacts 112, 113 mounted on switchblades 115, 116, the blade 115 being secured to a spring member 131 by a bow-spring 123. The blades 115, 116 and the member 131 together with a stop-member 117 and a bimetallic member 118 and insulating spacers 119 are secured together to form a blade assembly 121 which is attached to a disc 33-on which rests the cooking vessel-by a flexible arm 122 of poor heat conductivity, such as stainless steel. A heater 134 is associated with the bimetallic member 118. A second bimetallic member 124 has its upper end attached to the disc 33 in good heat-conducting relationship therewith, the lower end having a porcelain member 126 secured thereto in which member 126 is a conical recess 127. A conical link 128 has one end seated in the recess 127, the other end engaging the spring-member 131 which is normally biased to the left. In operation, as the temperature of the cooking vessel rises, the bimetallic member 124 will receive heat by way of the disc 33, thus the bimetallic member 124 will move to the left, the movement being damped by the heat-absorbing capacity of the member 126. When the cooking vessel reaches a predetermined temperature, movement of the member 124 causes the bow-spring 123 to move over-centre, thus closing contacts 112, 113 with a snap-action. Closure of these contacts energizes a circuit which includes heater 134 whereby bimetallic member 118 is heated and tending to rotate the assembly 121 by flexing the member 122. This rotation causes the bowspring 123 to snap in the opposite direction to re-open contacts 112, 113. Bimetallic member 118 may be adjusted by means of a screw 132. The detector unit is used with a further external bimetallic switch (Fig. 2, not shown) to control the heating of the cooking vessel.

Title: Improvements in and relating to variable speed gears
IPC: F16D67/00
Filed: 1934-09-25
Abstract: 442,562. Variable - speed epicyclic gearing. HARVEY, R., 33, Cranworth Street, Glasgow. Sept. 25, 1934, No. 27469. [Class 80 (ii)] Epicyclic variable-speed gearing automatically variable between solid drive and a definite minimum comprises primary and secondary driving-members 1,3 connected by means permitting slip, such as a centrifugal hydraulic coupling. The primary member 1 is connected by a sleeve 11 to a single sun gear 7. The secondary 3 is connected by a shaft 4 to two sun gears 8, 9 of different diameters. A driven shaft 12 is fast to a single sun gear 10. Loose on spindles 16 in a revoluble drum 14 are planets 17, 18 coupled together and independent planets 19, 20 also coupled together. The coupled planets 17, 18 mesh with the gears 7, 8 respectively, and the coupled planets 19, 20 with the gears 9, 10. With a light enough load, the gearing turns solid, transmitting the torque of the engine. Increased load causes relative rotation in the gearing and slip in the coupling. The drum 4 cannot rotate backwards because a one-way brake 15 prevents it. When the brake 15 is operative, the torque transmitted to the shaft 12 is augmented by the moment exerted by the brake, the speed-ratio being minimum. Reversed drive is by suitable additional means. Such means may comprise a train driving reversely from the sleeve 11 to the drum 14. Reversed drive of the shaft 12 is effected when this additional train is brought in by braking a carrier of intermediate idlers while the one-way brake 15 is rendered inoperative.

Title: Improvements in or relating to methods of producing unsaturated primary alcohols more particularly those of the vitamin a series
Filed: 1956-09-11
Abstract: Unsaturated primary alcohols are produced by reducing an acid chloride, acid bromide, acid or ester thereof of the unsaturated aliphatic or mixed aliphatic-alicyclic series by means of a di-alkyl aluminium hydride.  ("Mixed aliphatic-alicyclic series" means compounds where an aliphatic chain is linked to an alicyclic ring). Preferably the alkyl groups in the dialkyl aluminium hydride contain 1-6 carbon atoms, and the reduction is carried out between -50 DEG and +50 DEG  C., in the presence of an inert solvent.  In an example, b -ionylidene acetic acid ethyl ester in n-hexane is reduced by di-isobutyl-aluminium hydride in n-hexane at 5 DEG  C., the reaction taking place in an atmosphere of nitrogen, moisture being excluded. The reaction mixture is decomposed with moist ether and acidified with dilute hydrochloric acid to yield b -ionylidene ethanol.  This compound is also prepared by reduction, under the same conditions, of b -ionylidene acetylchloride by di-isobutyl aluminium hydride in n-hexane, and of b -ionylidene acetic acid and its ester by di-ethyl aluminium hydride in benzene.  Similarly is prepared Vitamin A from Vitamin A acid methyl ester, Vitamin A acid chloride, and Vitamin A acid using diisobutyl aluminium hydride in n-hexane, cyclohexane and ether/petroleum ether, respectively.

Title: Automatic cancellation of false calls in an elevator system
IPC: B66B1/16
Filed: 1969-06-02
Abstract: 1,271,847. Lift control systems. WESTING- HOUSE ELECTRIC CORP. 2 June, 1969 [26 June, 1968], No. 27798/69. Heading B8L. In a lift system registered calls are cancelled if the lift stops a predetermined number (e.g. two) of times without the passage of a load (passengers) through the entrance/exit being detected. The object is to prevent delay due to " false calls " maliciously or playfully made, whilst allowing for the occasional (e.g. one) genuine error. The invention is applied to the car call register only, which comprises relays having self-holding circuits, all of which are interrupted when a counter (also comprising relays) reaches a count of two; the counter is operated when the doors are nearly re-closed after a stop at which a light beam type detector has not been interrupted and is reset when the light beam is interrupted, i.e. at a genuine call stop. The counter is not operated if the stop was in response to a hall call. In an alternative embodiment calls are not cancelled unless more than a predetermined number remain in the register when the count of two is reached. This is effected by a current sensitive relay, the current through which is made proportional to the number of calls registered at any time by a resistor network. The detector may be made to respond to exiting loads only.
