Title: Improvements in and relating to thermostatic control in the heating of liquids
IPC: H05B1/02
Filed: 1929-08-23
Abstract: 338,597. Jackson Electric Stove Co., Ltd., and Smith, F. Aug. 23, 1929. Heating by electricity.-In a system of heating fluids by electricity in which the temperature is regulated by a thermal switch immersed in the fluid, the thermal switch is provided with an auxiliary heater adapted, should the switch or the portion of the fluid container near the switch become uncovered by the fluid, to cause the switch to act rapidly to cut off the supply of current to the main heater for the fluid. The auxiliary heater may be arranged in parallel or series with the main heater and the thermal switch may break the circuit to both heaters directly or may break the circuit of a contactor switch which in opening breaks the main heater circuit. In another arrangement, Fig. 8, a circuit through the main heater 32 is normally closed through the contacts 33 of the thermal switch. If the fluid level falls, a float 39 closes at 38 a parallel circuit to the auxiliary heater 35. Opening of the contacts 33 breaks the circuits to both heaters. Fig. 11 shows another arrangement in which the thermal switch when heated turns a mercury tube 53 in a clockwise direction. Parallel circuits are normally closed through the main heater 32, the auxiliary heater 35 and an extra " pilot " heater 52. When the liquid reaches, say, boiling point, the tilting of the tube 53 breaks the circuit to the main heater 32. Should the thermal switch become uncovered, it is heated further by its auxiliary heater 35 and the circuits to the latter and to the pilot heater are also broken. The invention is applicable to fluid-containers heated by immersion heaters or by heaters on the sides and bottom.

A thread rolling machine includes a rotatable die 7 mounted on a first spindle 4, the die cooperating with a die segment 9 mounted non- rotatably on a second spindle 5, and a mechanism for feeding blanks 11 between the die 7 and segment 9. The spindle 5 is supported in a carriage 2 which is urged hydraulically towards the die 7 against the constraint of an adjustable stop 44. Further stops 23, 24 permit adjustment of the segment 9 relative to the die. The feeding mechanism includes a driving plate 28, Fig. 2, keyed to the spindle 4 and supporting a freely rotatable control plate 32. An arcuate feed member 41 is attached to the control plate and oscillates with the plate to successively push blanks 10 from the hopper 11, past a leaf spring 42, to the leading edge of the segment 9. To oscillate the plate 32 a spring-loaded plunger 29, housed within the continuously rotated plate 28, engages a pin 33 attached to the plate 32, thus urging the plate 32 to rotate with the driving plate 28. This rotation is stopped when an edge 40 of the plate 32 engages an abutment 37, the plunger 29 then being retracted against its spring to disengage the pin and allow the plate (32) to be returned by a spring 36 to its initial position. A number of control pins may be provided, thereby rolling more than one blank for each rotation of the die 7.

Title: Systems for processing a colour composite signal
IPC: G11B20/02
Filed: 1975-06-19
Abstract: 1519151 Television AMPEX CORP 19 June 1975 [28 June 1974 (2)] 26139/75 Heading H4F To eliminate timing errors from colour television signals of the NTSC type played back from a magnetic tape a luminance-coherent subcarrier reference signal is generated from the separated sync component and used to correct phase errors in the separated chrominance component or encode the separated colour components after they have been phase corrected in response to a subcarrier reference signal generated from bursts separated from the chrominance component. These methods of timing error correction ensure coherency of the signals horizontal sync and colour burst components (i.e. coherency of the luminance and chrominance components) and thus enable conventional line-to-line time base correction using a plurality of delay lines to be effected upon the resulting output signal. In Fig. 1 the composite colour television signal from a magnetic tape is separated into its luminance component (2À7 MHz high pass filter 9) and its chrominance component (767 KHz band pass filter 14-the chrominance component having been frequency-transposed before recording). The chrominance component is frequency-converted by balanced modulator 15 to its nominal frequency at 3À58 MHz in response to a 4À347 MHz input from balanced modulator 23 which receives the 767 KHz output of VCO 22 and 3À58 MHz output of subcarrier generator 10 (Fig. 2 not shown) controlled by the horizontal sync pulses separated 31 from the luminance component. VCO 22 is controlled by the output of phase detector 21 which receives the output of subcarrier generator 10 and the bursts separated 20 from the corrected chrominance component. Modulator 23 may be omitted if oscillator 22 has a nominal frequency of 4À347 MHz. The prior art system using a stable crystal reference oscillator 26 of 3À58 MHz may be modified to include the coherent subcarrier generator 10 by including switch 18. Two further embodiments are described with reference to Figs. 3 and 4 (not shown). In a fourth embodiment Fig. 5 band pass filter 83 of 3À58 MHz separates the chrominance component from the luminance component. This chrominance component is decoded into I and Q signals in response to a VCO 88 controlled by a phase detector 87 in response to the separated bursts 85, to thereby eliminate phase errors. These I and Q signals are then encoded 89 onto a sync coherent subcarrier from generator 10 in response to line sync pulses separated from the luminance component.
