Abstract: 931,056. Automatic temperature control. KING-SEELEY THERMOS CO. Oct. 26, 1959, No. 36243/59. Class 38 (4). In a system in which self-interrupting contacts supply pulses of electrical energy to a load from a constant voltage source so that the average supply is dependent on the temperature of a body, the position of one contact is determined by a resistor dependent on the temperature and the other contact is oscillated independently of the temperature or load current. In Fig. 5 a U- shaped bi-metallic element of a thermally operated switch 20e has one limb fixed at one end and the other limb associated with an electric heater energized from an A.C. source 10e through contacts of the switch so that the switch operates intermittently to maintain a constant average voltage across the heater despite variations in the voltage of source 10e. This constant average voltage is applied to a series circuit including heaters 62e, 98e of bi-metallic elements 68e, 100e, and a resistor 66e having a negative temperature coefficient and responsive to a temperature to be measured and/or controlled. Movements of bi-metallic element 68e operate a pointer 70e to indicate the temperature and bimetallic element 100e operates a contact 102e associated with a contact 108e to control through a relay 110e the energization of a main heater 114e so that temperature is maintained constant at a value indicated by a pointer 86e and selected by manual operation of a cam 82e positioning the other limb of bi-metallic element 100e. Intermittent operation of contacts 102e, 108e is produced by a further bi-metallic element 104e associated with an electric heater 106e the energization of which is controlled by contacts 102e, 108e so that they are self-interrupting with a ratio of on/off time dependent on the extent of deviation of the temperature from the set value. Modifications are described in which: (a) temperature setting is effected electrically by a variable resistor in series or parallel with the temperature variable resistor; (b) the temperature variable resistor has a positive temperature coefficient; (c) the main heater is replaced by a visual or audible alarm which operates at a selected temperature. Application to the temperature monitoring of refrigerators, cookers and rooms is referred to.

Abstract: 1,201,197. Planning boards. A. BERGE. 8 Aug., 1967, No. 36465/67. Heading G5C. The board comprises : a panel 1; parallel rows 1, 1a of display support means (e.g. rails); a scale 16 representing a common dimension, e.g. time, pertaining to the activities displayed; indicator members 5, 5a positioned in the rows; optional spacer elements 30; the members 5, 5a of each of certain rows (as shown, rows A1-A5) displaying identical markings. As shown, it is desired to optimize utilization of labour and plant in a factory. Rows A1-A5 are chosen as the "leading dimension": workpieces. Rows B1-B3 and C1-C5 are dimensions representing labour and plant respectively. Markings 01, 02 ... (carried by members 5, 5a) represent a cogwheel, a shaft, &c. By arranging these members on the board it is possible to see at a glance that e.g. at Day 1, hour 2, the cogwheel ("01") is being/to be processed by Anderson on the lathe. The "leading dimension" (A1-A5) indicates whether "gaps" exist in the jobs scheme, i.e. whether certain workpieces are not being processed. Rows 1, 1a refer to planned and achieved programmes respectively. Should a machine breakdown occur the "multipler" effect of this can easily be seen and the programme readily re-planned. Construction.-As shown in Fig. 2a the indicator members 5, 5a are supported by runners 2, 2a sliding on rails 1, 1a. Wires 4, 4a constitute vertical markers; wires 4a are supported by sliders 28 and wires 4 by grooved rods 23, 24 and springs 18. In Figs. 8-10 (not shown), wires 4a hang between endless conveyer belts (80, 81) so that they may be moved simultaneously. In Figs. 11-12 (not shown), there exists an additional time scale (116) supported by an endless belt: this represents the achieved programme. The runners 2, 2a may be replaced by pins, cards, magnets, lamps, &c. Other applications relate to constructing school timetables (Fis. 3, 4, not shown), transport, econometrics, &c.
