Title: Method of Operating Electrodes for Projectors.
Inventor: SPERRY ELMER AMBROSE
IPC: H05B31/00
Filed: 1916-04-28
Abstract: 100,781. Sperry, E. A. June 28, 1915, [Convention date]. Are lamps. - In a projection lamp, a highlylumincus flame 11 from the positive electrode 1 is confined within the crater by a negative flame 8 which brushes across the mouth of the crater. The positive electrode is cored with material such as cerium or other rare-earth fluorides, giving a white flame. The force of the negative flame may be increased by impregnating a soft core of the negative carbon with arc-sustaining but not necessarily luminous material, for instance potassium horate or silicate. This effect is enhanced by using a large current, say 90-150 amperes. A high positive current-density, say 500 amperes per sq in., is also employed. The arc may be about an inch long. Fig. 6 shows a suitable arrangement of the electrodes. If the negative electrode is at a considerable angle to the axis of projection, the negative flame may be directed by a magnetic coil 15, Fig. 7, around the arc. The positive electrode may be rotated to ensure symmetry and to cause deposition of graphite around the rim of the crater. The Specification as open to inspection under Sect. 91 (3) (a) states also that the negative flame may be directed by a jet of vapour or gas from a passage in or jacket around the electrode, which may be coated with copper. This subject-matter does not appear in the Specification as accepted.

Abstract: 1463988 Automatic control SATCHWELL CONTROLS Ltd 11 Feb 1975 [12 Feb 1974] 06372/74 Heading G3N A control means for regulating a temperature control system so that a desired temperature is attained in an enclosure at a predetermined time is responsive to a temperature set point signal which changes at a predetermined rate during a pre-set period before the predetermined time and signals representative of temperatures inside and outside the enclosure.  As shown, operational amplifiers A2-A6 are inter-connected to provide a heating delay, in a pre-heat period, in dependence on the outside temperature to and the actual temperature t b within the building, so that heating appliaces of the building will be operated for the minimum period that will ensure that the building is at a temperature suitable for occupancy. The building temperature t b is provided from a bridge B1 in the non-inverting input to the amplifier A2 and the desired difference between day and night temperature set into the inverting amplifier A2 from a potentiometer P8. The output of amplifier A2 is applied to amplifiers A4, A6. The amplifier A6 controls a triac TR2 when the building temperature t b reaches the day set temperature t d and the control of the heating appliances is then taken over through a time switch, not shown, by occupancy period control circuits. The amplifier A4 operates during the night to control a triac TR1 so that the building temperature does not fall below the day temperature by more than the desired difference. Switch-on of the heating devices during the preheat period is effected by an amplifier A5 to the non-inverting input which is applied a signal from a potentiometer P2 driven by a time switch so as to move linearly between night and day temperatures during a maximum pre-heat period; a potentiometer P1 setting the duration of the pre-heat period and a potentiometer P5 the duration of an extended pre-heat period, when contacts TS1 of the time switch are open. Compensation for the outside temperature t o is provided by a bridge B through the amplifier A3 to the inverting input of the amplifier A5.
