Title: Improvements in automatic temperature regulators
IPC: G05D23/22
Filed: 1940-04-02
Abstract: 540,104. Automatic control of electric furnaces &c. UEHLING, F. F. April 2, 1940, No. 5946. [Class 38 (iv)] [Also in Group XXXVIII] Temperature.-A temperature control system, illustrated as applied to an electric furnace 28 the current supply to which is controlled by contacts 98 of a relay 94, comprises a galvanometer 29 responsive to temperature measured by a variable e.m.f. such as that of a thermo-coupler 27 and a resistance 15, included in the galvanometer circuit in which a potential is developed tending to accentuate the pressure of the moving contact 34 actuated by the galvanometer when it touches either of the contacts 35, 36 on high and low temperature conditions respectively. Relays 48, 37 are selectively energized through these contacts to actuate a reversible motor 1 driving a contact 6 of a potentiometer 5 whereby the thermo-couple EMF is balanced and the galvanometer contact 34 centralized in step by step movements. These steps are produced by a relay 50 which is energized through contacts 53, 56 on the relays 37, 48 respectively to cause intermittent action thereof. The energizing currents of relays 37, 48 pass through the resistance 32 and cause the galvanometer to increase its contact pressure. A contact 13 is driven by the motor 1 so as to correspond in position with the temperature of the furnace and a contact 14 is pressed against contact 13 by a spring 12 until, as the temperature falls below that desired, it is separated therefrom by an abutment 15 set by an indicator 22 in accordance with that temperature. This separation releases a relay 94 whereby contacts 98 are closed to establish the furnace heating circuit. Contacts 91 in series with the relay coil and with contacts 13, 14 open to prevent re-energization, of relay 94. Only when contacts 82 are closed by the first movement of relay 48, which occurs when contact 35 is next engaged after a rise of furnace temperature can the relay 94 be re-energized. Similarly when relay 94 has been energized its deenergization is prevented by contacts 93 until the opening of contacts 102 on the first energization of relay 37, which occurs when contact 36 is next engaged after a fall in furnace temperature. The arrangement is such that sparking at the galvanometer contacts and chattering of relay 94 are prevented.

Title: Improvements in or relating to carrier signalling systems
IPC: H04J1/04
Filed: 1936-02-28
Abstract: 472,816. Multiplex transmission. GENERAL ELECTRIC CO., Ltd., WESTELL, E. P. L., and LEY, D. A. Feb. 28, 1936, No. 6025. [Class 40 (iv)] [Also in Group XL] In a multiplex two-wire or four-wire carrier system, each channel comprises a two-stage modulator M1 .. M12 in which the speech first modulates a frequency which is the same for all channels and is comparatively low but is at least twice the highest speech frequency, one of the side-bands then modulating a carrier characteristic of the channel and one of the resulting side-bands being selected for transmission and amplified at 1A .. 12A. The odd and even channels are associated with the multiplex line through separate impedances 25, 26 as described in Specification 405,026, [Group XL], to limit inter-channel interference. The carriers at one end are derived from a common oscillator O and harmonic producer H which comprises a frequency doubler followed by a square-wave generator of the kind described in Specification 428,708, [Group XL], and those at the other end are derived from currents transmitted with the signals and acting also to control the gain of the amplifiers on the route, e.g. as described in Specification 463,409. The stand-by and main oscillators may be at opposite ends. Demodulators D1 .. D12 are constructed and arranged similarly to the modulators. To save apparatus, pairs of second modulators may use the same carrier, upper and lower side-bands respectively being selected for transmission. Two-stage modulators and demodulators. In one arrangement, Fig. 2 (not shown), both stages comprise two-rectifier arrangements, but as shown in Fig. 3A the first modulator comprises a four-rectifier arrangement which is very much less favourable to third order modulation products than the tworectifier arrangement and so makes it possible to use a simpler filter at 12. The demodulators Fig. 3B are identical except for the situation of the potentiometers for balancing out residual carrier current. By suitably mismatching the impedance of the low-pass input filter 9 to the impedance of the modulator 11 and the band-pass filter 12, and by mismatching the input impedance of filter 12 to the modulator 11 and the filter 9 and by suitable design of the filter 12 the circuit can be made to be free from or to compensate for distortion. Attenuation pads may be associated with the first modulators to limit the degree of mismatching and with the second modulators to compensate for distortion.

Abstract: 950,180. Printing-surfaces. R. W. CRABTREE & SONS Ltd. Feb. 22, 1960 [Feb. 23, 1959], No. 6186/59. Heading B6C. A printing cylinder C has plate end clamps 5 disposed to clamp a printing plate P by its curved ends and other side plate clamps 11 to clamp the plate by its side edges and a single actuating means for operating the end and side clamps. As shown, the side clamps 5, Fig. 1, are actuated by screwed rods 4 carrying gears 3 rotated by gears 6 (Fig. 2, not shown) on an operating member 7, Fig. 1. The gears 3 are urged to the right to exert a clamping action on the plate P by springs 14. The clamps 11 are staggered for engagement with adjacent plates in the manner shown in Fig. 1, each clamp having a projecting tongue 12. The clamps 11 are moved into clamping position by eccentrics 10, Fig. 5, mounted to turn on stubs 10c in fixed plates 10a and having drive pins 10b. The pins 10b are connected to links 8 connected to pins 23a on carriages 23 mounted in a bar 1. The bar 1 is slidable in a groove in the cylinder C, Fig. 1, the carriages being moved by the bar 1 by springs 15 (Fig. 3, not shown). The bar 1 has extensions 2, Fig. 1, engaging the gears 3. Thus, when member 7 is turned in the appropriate direction the rods 4 cause the clamp 5 to move into clamping engagement with the plate C, further turning causing axial movement of the rods 4, gears 3, and bars 1, thereby causing the eccentrics 10, Fig. 5, to pull down the clamps 11.
