Title: Improvements in or relating to automatic control systems
Inventor: HILTON KENNETH GEORGE
IPC: G05B19/07
Filed: 1963-10-03
Abstract: 1,102,955. Sequential control systems; control of motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 30 Sept., 1964 [3 Oct., 1963], No. 39041/63. Headings H2H and H2J. A module comprising AND, OR and NOT gates is arranged as an assembly with similar modules to provide a control action, or a sequential control system. The modules M17-M19 control a series of operations in a sequence such that a fault in any operation energizes an alarm and prevents the sequence proceeding. The module M18 controls the driving of a pulverizing mill 53 by an electric motor 57. With the mill at rest, there is no input on terminal B from tachogenerator 59. With terminal XM unconnected, there will be no output from OR gate 17 hence an output from the NOT gate 19 is applied to one input of AND gate 5. Without a signal from a timer 52 on terminal G, AND gate 3 gives no output and without an input signal on terminal Y (N+1), there will be no inputs on OR gate 11 hence no output from OR gate 11 or AND gate 13, hence there will be no output from amplifier 15 to the NOT gate 39, which provides a second input to the AND gate 3. When a third input is applied to gate 5 from terminal D module M17 to terminal A module M18, the AND gate 5 gives an output on terminal E causing a controller to start the motor 57. At working speed, the tachogenerator 59 output on terminal B causes OR gate to give an output so that NOT gate 19 has no output. Consequently the gate 5 output dissappears and with no output on terminal E the controller 55 remains energized by a hold relay (not shown). The NOT gate blocking also causes AND gate 13 to block all signals from the input to amplifier 15. When timer 15 applies its delayed signal to terminal G this signal does not pass through gate 13. The output from gate 17 is applied through terminal GL and lead gl to the green lamp 41. Persistence of the signal from terminal D module M17 provides AND gate 17 with two inputs and through amplifier 23 will apply a signal to output terminal D, module M18, which passed to module M19 causes this to initiate a further control action. In the event of mal-operation the motor 57 will not be started and tachogenerator will not have an output, thus when a signal appears from the timer 52 this with the signal from terminal D module M17 causes AND gate 3 to produce an output and OR gate 11 to produce an output. As the NOT gate 19 is already providing an output, gate 13 will conduct passing a signal through terminal AL to a red lamp 45 and alarm 47. A fault within the module will cause an amber lamp 49 to be illuminated. The gates may be of the pneumatic, semi-conductor or magnetic gate types.

Abstract: 1520645 Colour television RCA CORPORATION 24 Sept 1975 39153/75 Heading H4F Burst phase errors in a composite colour television signal of the NTSC or PAL type, e.g. introduced as a result of magnetic recording and playback, are corrected to provide a stabilized chroma signal. In a first embodiment, Fig. 1, an NTSC type chroma signal is separated 100 from the composite television signal and demodulated 102, 103 using a stable subcarrier C to provide a baseband chroma signal containing the burst phasing errors. Error signals representative of the phase errors of the burst component are developed 206-209 from this baseband chroma signal and used to modulate 210,211 the stable subcarrier C to provide a subcarrier having the same phasing errors as the original chroma and burst components. This rephased subcarrier D is then used to remodulate 107, 108 the baseband chroma signal to provide a stabilized chroma signal which is added 112 to the appropriately delayed 110 luminance signal. In a second embodiment, Fig. 2, an NTSC/PAL switch 400 is included which with switch 303 converts the switched PAL burst to unswitched NTSC format. In this embodiment the chroma signal is separated 200 (or 302) from the composite television signal and demodulated 201, 202 using a stable subcarrier C to provide a baseband chroma signal containing the burst phasing errors. Error signals representative of the phase errors of the burst component are developed 206-209 from this baseband chroma signal and used to modulate 210, 211 the stable subcarrier C to provide a subcarrier having the same phasing errors as the original chroma and burst components. This rephased subcarrier D is used to demodulate 102, 103 the separate chroma signal to provide a baseband chroma signal free of the original phasing errors which is then remodulated 107, 108 on the stable subcarrier C to provide a stabilized chroma signal which is added 112 to the appropriately delayed 110 luminance signal.

Abstract: 1313565 Polyurethane elastomers SOC MARLES - KUHLMANN - WYANDOTTE 17 Aug 1970 [18 Aug 1969] 39485/70 Heading C3R Polyurethane elastomers are prepared by forming a homogeneous phase by incorporating in a liquid isocyanate-terminated adduct reagents which, in the absence of the adduct, would provide a solid linear polyurethane, the polyurethane containing isocyanate groups available for reaction with a curing agent, and curing the resulting material with a curing agent containing groups reactive with isocyanate groups to form an elastomer, the adduct being the reaction product of an organic polyisocyanate with a linear alcohol having two OH groups and a branched chain alcohol having more than two OH groups. The alcohols used to prepare the liquid adduct are suitably polyether polyols. The normally solid linear polyurethane may be prepared by reacting a diol, e.g. a monomeric low M.W. glycol and/or a polyalkylene ether diol with a diisocyanate in the liquid adduct. For hard elastomers it is preferred to use a chemically hindered, aromatic diamine as curing agent, but other diamines may also be used. Relatively soft elastomers are prepared by employing polyols as curing agents. In a typical example, a liquid NCO- terminated adduct is prepared by reacting a polyoxypropylene triol and a polyoxypropylene glycol with tolylene diisocyanate. Tolylene diisocyanate and tripropylene glycol are then added to the adduct, followed by diethylene glycol to chain extend the TDI/tripropylene glycol prepolymer into a normally solid linear NCO-terminated urethane polymer dissolved in the liquid adduct. This formulation is then cured with 4,4<SP>1</SP>-methylene-bis-(2-chloroaniline).

Filed: 1973-08-24
Abstract: 1434205 Television SONY CORP 24 Aug 1973 [28 Aug 1972] 40233/73 Heading H4F A television receiver includes independently manually controlled brightness and contrast control circuits and an automatic brightness limiting circuit actuated in response to the detection of excessive CRT beam current which does not reduce the quality of the reproduced image by cutting out low brightness video signals, i.e. an automatic brightness and contrast control. The video signal at input 6 is fed via transistors Q 1  and Q<SP>1</SP> and amplifier 5 to the CRT 2. Resistor R 3  comprises the brightness adjustment, resistor R 4  the contrast adjustment, and resistor R 1  senses the beam current and via transistor Q 2  effects the automatic brightness and contrast control. Transistors Q 3  and Q 4  serve as variable current sources and transistors Q 5  and Q 6  as constant voltage sources for the transistors Q 1  and Q 8  respectively. The emitter of transistor Q 6  is grounded through resistor R 7  and diode D 1 , the connection point of which is coupled to a transistor Q 7  whose collectoremitter path is connected between the video signal transmitting path L and ground. The circuit Q 7 , R, and D 1  compensates for variations in the DC level of path L to avoid brightness change when the contrast is adjusted. If the beam current becomes large, transistor Q 2  is rendered conductive which increases the currents of transistors Q 3  and Q 4  and thereby the potentials at points B and C and the base potentials of transistors Q 5  and Q 6 . Thus the brightness and contrast are reduced thereby reducing the beam current.
