Fluid capsule 6, which may be connected to a remote bulb in capillary tube 40, actuates snap-spring 13 carrying contact 15 through a threaded spindle 9, an internally threaded wheel 10, a button 11 and a lever 19 pivoted at 20 and bearing on one end of snap spring 13. In the closed position, contact 15 engages fixed contact 18. When fluid capsule 6 expands, spring 13 snaps over, snapping back when capsule 6 contracts. Alternatively spring 13 is biased not to snap back in which case a button 22 is provided for resetting. Spring 13 is biased by grub screws 16 and 17, and a bore 21 may be provided so that screw 16 can be adjusted to adjust the snap differential. Alternatively screw 16 may be extended through the housing 3 and be provided with a knob. The temperature setting can be set by rotation of wheel 10 through an open end of housing 4. A collar 8 is fastened to the underside of capsule 6 and a spindle 7 is slidably and rotatably mounted in collar 8. Collar 8 is urged against spindle 7 by spring 12. Spindle 7 is threaded in the base of housing 4 and provided with a flat 41 for an adjusting knob by which spindle 7 can be rotated to move capsule 6 nearer or farther from spring 13 to set the operating temperature against an external scale. In some applications when spindle 7 is rotated to a certain position the contacts 15, 18 are to be open and held open and to do this a rod 24 is provided on spindle 7 and a rod 23 on collar 8. Then when spindle 7 is rotated to the required position protuberance 25 on rod 24 engages rod 23 and urges collar 8 upwards to operate spring 13. As an alternative to this arrangement a plate 42, Fig. 4, is fastened on the spindle and a lever 44 is pivoted on a stud 43 fastened to the base of the housing, with a sloping ramp 48 on plate 42 so that when plate 42 is rotated, ramp 48 engages end 45 of lever 44, pivoting it about stud 43 so that lugs 47 engage the underside of collar 8 to lift it and operate spring 13. A pointer may also be fastened by a collar to wheel 10.

Filed: 1968-12-10
Abstract: 1,221,842. Television. BATTELLE DE. VELOPMENT CORP. 10 Dec., 1968, No. 58566/68. Heading H4F. [Also in Division G2] A method of recording sequences of light and dark information which upon playback and display will appear in subjective colour (see Specifications 1,083,483 and 1,221,841), comprises selecting a coded sequence including a discharge phase, colour coding phase and white phase (see Fig. 5, the colour coding and white phase being combined for the different subjective colour sequences), preparing animation cells for the three phases in which the discharge phase is dark in the entire area in which the subjective colour is to be reproduced, the colour coding phase is dark in the area to appear in subjective colour and light in other areas, and the white phase is light in the area to appear in subjective colour and in other areas, and recording said cells in a step-by-step fashion in accordance with the sequence to store indicia of said light and dark areas on a recording media, and repeating the recording of the sequences a plurality of times to provide a sustained display of subjective colour when the sequence is displayed between 30 and 3 times per second. The repeating sequence of light and dark signals is recorded by a field by field or a frame by frame animation technique on a motion picture film using a movie camera, on a video tape using a television camera, or is programmed in a computer memory. With a motion picture camera the film is exposed frame by frame, combinations of animation cells being arranged and recorded to provide the desired frame by frame sequence, Figs. 4 and 5. With a television camera the video tape is recorded frame by frame or field by field. With a computer, a programme is prepared to provide a frame by frame pictorial read-out on a display such as a cathode-ray tube. The various combinations of dark and light signals (subjective colour codes) for producing various subjective colours are related in charts, Figs. 3A-3D (not shown), to physical colours in a standard notation such as the Munsell colour notation, these charts being formed by preparing various subjective colour codes and viewing the resulting respective subjective colours under given conditions and comparing these colours with known physical colours such as Munsell colour chips (Figs. 6A and 6B, not shown). The picture to be displayed may comprise a steady black and white image with a subjective colour portion or area inserted therein, either or both comprising "live" action, static shots, animated figures or letters, the information coming from motion film, video tape, slide or "live" pick-up. The insertion of the subjective colour area into the black and white image may be accomplished optically or electronically by special effects, film processing, or electronic keying. The Specification describes in detail the various possible subjective colour codes for the primary colours of red, green and blue for 60 and 50 field per second television standards.

Title: Alarm apparatus for facilitating the detection of an unautohorized removal of property
IPC: G08B13/24
Filed: 1972-12-21
Abstract: 1364349 Theft alarms ICI AMERICA Inc 21 Dec 1972 [20 Jan 1972] 59073/72 Heading G4N Apparatus for indicating the unauthorized removal of property through a localized detection field comprises means for preventing actuation of an alarm signal until the apparatus has entered and left the field, actuation of the alarm being initiated by the apparatus leaving the field. As described, the circuit is mounted in a dummy packet of bank notes, and is normally held deactivated by a magnetic switch 72 operated by a magnet in a cash desk drawer. When the packet is removed, switch 72 closes to connect the power supply to the circuit. Transistor 200 is then turned on so that diode 228 clamps point 230 to line 100. If the circuit is moved into an R.F. field of appropriate frequency, a signal is picked up by coils 106, 108 amplfiied by amplifiers 114, 146 and rectified by diodes 170, 172 to provide a D.C. control signal at the emitter of transistor 180. This signal fires SCR 190 to turn transistor 200 off, and is also applied to transistor 202 to turn it on, so that point 230 is still clamped to line 100 as long as the circuit remains in the R.F. field. If the circuit is now removed from the field, transistor 202 turns off again and point 230 is no longer clamped but can rise in potential as capacitor 226 charges through resistor 224. If the circuit remains out of the field the potential at point 230 will turn on unijunction transistor 250 after a predetermined delay and fire SCR 260 to initiate an alarm, e.g. smoke or explosion. If the circuit is returned to the field before unijunction 250 turns on, transistor 202 becomes conducting again, discharging capacitor 226 and preventing initiation of the alarm.

Filed: 1969-12-05
Abstract: 1291879 Pulse Circuits GENERAL INSTRUMENT CORP 5 Dec 1969 [5 Dec 1968] 59619/69 Heading H3T A pulse circuit comprises capacitance 32 chargeable by a first switch 52 which conducts transiently in response to the positive edge of the input pulse at 12 and chargeable from a source of different voltage through a second switch 54 which conducts transiently in response to the negative edge of the pulse. The capacitor may thus maintain an output at the two levels without drawing supply current as shown, when the signal is positive the corresponding voltage at 28 rises until it is clamped by conduction of the input diode of transistor 22, which transistor conducts and charges capacitance 32. Capacitor 64 effectively acts as a differentiating circuit so that 18 quickly cuts off leaving 18 charged to a value limited by forward conduction of the collector-emitter diode of 18. A negatively going signal similarly charges capacitance 18 to a limited negative  voltage. The capacitor voltage controls complementary transistors 68, 70 to correspondingly charge the output capacitance 74, the diode drops in the collector junction of 22 and the emitter junction of 68 being in opposition so that the output switches between the values of the values of the supply voltage. Discharge of capacitance 32while 68 and 70 conduct is compensated by feedback through capacitors 82 and 84. Diodes 40 and 46 limit the potential swing and ensure limited drift of the voltage across capacitors 64 and 66.
