Title: Magnetic recording and/or reproducing apparatus
IPC: H04N5/783
Filed: 1973-08-03
Abstract: 1415035 Controlling tape transport in video recorders SONY CORP 3 Aug 1973 [4 Aug 1972] 37039/73 Heading G5R A tape-transport control circuit 43 for a rotary-head video recorder 18 ensures that, on actuation of a control 44 at any time, the tape will start or stop in synchronism with the video signals, e.g. to permit immediate stop-motion playback, or editing without the introduction of phase-shifts, the actuation of the control 44 rendering the circuit responsive to video control signals, a predetermined one of which then causes the tape to start or stop. As shown, during recording alternate vertical sync. pulses separated 27 from the signal 10 trigger a monostable 29 to provide a series of control pulses at the frame frequency. Actuation of the control 44 to start or stop the tape sets a flip-flop 46; the next pulse from monostable 29, however, resets the flip-flop 46, which triggers a monostable 47 of adjustable time constant. The return of monostable 47 to its stable state switches a flip-flop 48 which operates a pinch-roller solenoid 24. The delay between the last pulse from the monostable 29 and operation of the pinch roller is made up of the time constant of the monostable 47 plus a mechanical delay, and the former is pre-adjusted so that the total delay is one frame period; the tape thus starts or stops synchronously with the next control pulse from monostable 29. This is achieved even when the mechanical delays on starting and stopping are not equal by a time constant control circuit 49. The control pulses are also recorded by a fixed head 35, and are compared 30 with pulses indicative of rotary head position in order to control the head motor 17 and synchronize the head rotation with the signals. During playback, the monostable 29 is triggered either by the control pulses played back by head 35 as shown; or by vertical sync. signals separated from the reproduced video signal, Fig. 6 (not shown); or by the synchronized head position control pulses, Fig. 4 (not shown). A circuit (57-59), Fig. 7 (not shown) may be included which monitors the head speed and closes a gate (56) to inhibit operation of the transport control circuit if the head speed falls below a certain level.

Title: Improvements in and relating to the manufacture of diaryl oxides from phenols
Inventor: CRAGGS HAROLD CLEVELAND
IPC: C07C43/263
Filed: 1963-09-23
Abstract: In a process for the dehydration of a phenol to a diaryl oxide any unreacted phenol is recovered from an aqueous solution by contacting the solution with a diaryl oxide, at a temperature at which the diaryl oxide is liquid (e.g., 30 DEG -60 DEG  C.), separating the diaryl oxide and aqueous phases, and subsequently separating the phenol from diaryl oxide in a distillation column of the phenol dehydration process.  The aqueous solution of the phenol may be obtained as a by-product in drying by distillation the phenol recovered from the reaction product of the diaryloxide process.  The phenol may be substituted, e.g. by alkyl.

Filed: 1966-08-19
Abstract: 1,156,392. Controlling oxygen steelmaking. INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE. Aug. 19, 1966 [Aug. 27, 1965], No. 37374/66. Heading C7D. In the refining of crude iron with oxygen, the rate of carbon removal is continuously monitored and from it is established a decarburization curve, relating decarbization rate to a parameter linked to carbon removal; suitable parameters are time or quantity of oxygen blown in. This curve is then extrapolated by fitting to the curve at at least two points an extrapolation curve preferably of the form Y = Ae<SP>-bt</SP>, where Y represents decarburisation rate, A and b are co-efficients representative of the curve, and t is the parameter linked to carbon removal. Integration of this curve then indicates the carbon content in terms of parameter "t", and hence the point at which blowing showed stop to obtain the deserved value. Fitting of the curve and subsequent calculation is done by computer in view of the speed required; the computer may also be arranged to control the process automatically.

Abstract: 874,295. Ice-making. VILTER MANUFACTURING CO. Nov. 5, 1959 [Aug. 27, 1959], No. 37492/59. Class 29 In flake ice-making apparatus in which water is sprayed from annular header 19 on to the inner surface 17 of a vertical cylindrical evaporator 8 and knives 16 carried by rotor 12 remove the ice in flakes which fall through the bottom of the machine to a collector, scrapers 45, 46 carried also by the rotor remove ice from the lower part of surface 17 and from the undersurface of the bottom plate 30 of the evaporator. Unfrozen water is collected in an annular gutter 22 which is prevented from rotating by having its discharge pipe 24 passing through an aperture in the wall 9 of spider 11 which supports the evaporator. The gutter has a central hub which embraces an eccentric 23 on the rotor 12. This causes the gutter so to gyrate that that part which is under the knives 16 is displaced outwards of the surface 17 so that the flake ice will not fall into the gutter. Ice removed by scrapers 45, 46 falls through the spider 11 and into the gutter respectively. Pipe 24 feeds into a collecting chamber 25 from which water can be recirculated to header 19. A heater 50 around wall 9 also prevents ice accumulation. The bottom bearing 37 of rotor 12 can be removed through the bottom of the apparatus.

Filed: 1972-08-14
Abstract: 1380177 Automatic control of arc furnaces ASSOCIATED ELECTRICAL INDUSTRIES Ltd 10 April 1973 [14 Aug 1972] 37800/72 Heading G3R [Also in Division H2] A circuit for controlling the movement of the electrodes E1-E3 of a three phase arc or electroslag refining furnace comprises three voltage transformers T1-T3 each having a primary winding P1-P3 and two secondary windings S1À1-S3À2 which are connected in pairs in series opposition, and actuators M1-M3 each responsive to the difference between the voltages across an associated pair of secondary windings for moving the corresponding electrode in a direction which tends to reduce the voltage difference. The electrodes are supplied with current from a transformer T and a current regulator CR, the electrodes being carried by supports movable by electric motors which are controlled by the actuators M1-M3. The difference voltages which control the actuators ensure that a constant arc voltage is maintained by moving the electrodes towards or away from the molten material thus reducing or increasing the electrode voltage and reducing the voltage difference. In a modification current transformers in the phase leads L control relays having contacts connected to the secondary windings S1À1-S3À2 so that if the current supply to an electrode falls to zero, correct single phase control of the movement of the other electrodes continues.
