Title: Improvements in and relating to electric hotplates
IPC: F24C15/10
Filed: 1949-05-31
Abstract: 674,959. Control systems for heating resistances. BRITISH THOMSON-HOUSTON CO., Ltd. May 31, 1949 [June 3, 1948], No. 14596/49. Class 38 (iv). [Also in Group XI] An automatic heat-controlling means periodically interrupting the heating current to an electric hot-plate comprises two co-operating contacts 26 and 27, one contact 26 being periodically moved into and out of engagement with the other contact 27 by a constant speed motor 32, and the position of the other contact 27 being controlled by a temperature responsive element 12 and by a manually adjustable knob 38. The temperature responsive element 12 is in a heat insulating tube 15 having a heat conductive cap 14 to which one end of the element 12 is secured. The cap is adapted to come into heat conducting relationship with the base of a cooking vessel when the latter is placed on the hot-plate and any increase in temperature of the cooking vessel causes the lower end of the element 12 to move to the right, thereby displacing the contact 27 in a manner varying the period of time that the heating circuit is energized. The lower end of the element 12 is connected to a rod 39 slidable in a support 43. On a threaded part 40 of the rod 39 is a nut 41 connected to the contact 27 so that an additional control of the hot-plate is obtainable by turning the rod 39. The heat insulating tube 15 and additional heat reflecting tubes 18 protect the element 12 from the heat radiated by the heating elements 2. The tubes 15 and 18 are spring supported to ensure a good contact with any vessel on the hot-plate.

Title: Element position detector system
IPC: G05D3/12
Filed: 1972-03-29
Abstract: 1367731 Knitting machines NORTH AMERICAN ROCKWELL CORP 29 March 1972 [30 April 1971] 14662/72 Heading D1C In a circular knitting machine wherein the pattern jacks 10 are either raised to knit position or left in non-knit position, a detector system projects light against the edges of jacks when in the non-knit position and collects a portion of the light reflected thereby to generate a voltage output which indicates the presence of a jack in this position. As shown, jacks 10 are in a 1x1 select position such that alternate needles will knit. Light conducted from a source 20 impinges on jacks in their lower position and light reflected is conducted back to photocell 21 or the like by fibre optic cables 13, 14. The pulse from photo cell 21 passes to a one shot multi-vibrator 25 which delivers a pulse of constant amplitude and length to NAND gate 26 and AND gate 27. A second pulse comes from the command system controlling the pulsing of individual jack actuator mechanisms at each yarn feed and is fed to NAND gate 26 and AND gate 28. When there is no fault, the two pulses will coincide at NAND gate 26 giving no output so that there will be no output from AND gates 27, 28. If there is wrongly no jack in the down position there will be no pulse from the sensor and AND gate 28 will receive pulses from NAND gate 26 and the command system indicating an up error. Similarly if a jack is wrongly in the down position AND gate 27 will receive pulses from NAND gate 26 and the sensor indicating a down error. OR gate 29 will give an output indicating all errors.

Title: Improvements in or relating to apparatus for the electrical production of heat for boiling, cooking or other purposes
IPC: F24C7/08
Filed: 1934-05-18
Abstract: 440,185. Control systems for heating resistances ; electric transformers ; variable resistances. BERRY, A. F., Wellington House, 125, Strand, London. May 18, 1934, No. 15049. [Classes 38 (ii) and 38 (iv)] [See also Group XXXVI] In electric heating-apparatus employing low voltage resistance heating elements 1, of non- ferrous metal, permanently connected to the secondary 3 of a transformer, an additional resistance is included in the secondary circuit which is automatically increased after a predetermined time from a low to a high value such that the transformer is initially overloaded, to effect rapid heating of the elements, but after the predetermined time the load is reduced to a value at which the transformer can continuously operate in safety. The transformer casing contains heat storing material which absorbs and then dissipates the extra heat developed during overloading. The resistance may comprise iron bars 5 associated with heat absorbing masses 6 which produce a time lag in the increase in temperature and resistance of the bars due to passage of current. In Fig. 2, the resistance comprises resistance strips 5<b> initially short-circuited over the major portion of their length by copper bars 7. The short-circuit is removed when the strips bend under expansion produced by the heating effect of the current. In Fig. 4 a steel helix 13 is initially short-circuited by a copper tube 12. The helix rotates under the heating effect of the current to remove the short-circuit by operating contact 15. In Fig. 3 the resistance 8 is initially short-circuited by bars 2<x>, 2<y> with contacts 2<c>, 2d. On expansion due to heat, the contacts move into abutment with insulating portions 9 to remove the short-circuit.

Title: 1, 2-epoxy-2-methyl pentane and its conversion to 2-methyl-pentanal-1
Inventor: REED HUGH WILMA BOULTON
IPC: C07D303/04
Filed: 1956-05-18
Abstract: The invention comprises the new compound 1.2-epoxy-2-methyl pentane. It may be prepared by treating 2-methyl-pentene-1 with hypochlorous acid, thus forming 1-chlor-2-methyl-pentanal-2 and treating the latter with a strong alkali, for example, sodium hydroxide. Alternatively 2-methyl-pentene-1 may be oxidized directly to 1.2-epoxy-2-methyl-pentane by means of perbenzoic acid.  On distillation with a dilute mineral acid 1.2-epoxy-2-methyl pentane is converted to 2-methyl-pentanal-1. In the example 2-methyl-pentene-1 is added to a solution of perbenzoic acid in chloroform, the mixture is extracted with aqueous sodium carbonate to remove the benzoic acid formed and the chloroform solution left is distilled to give 1.2-epoxy-2-methyl pentane.
