Patent GB-854923-A (GB)
Title: Preparation of methyl ª‰-cyanoisobutyrate
Filed: 1957-05-08
Abstract: Methyl b -cyanoisobutyrate is prepared by reacting hydrocyanic acid and methyl methacrylate at superatmospheric pressures in the range of 50 to 2,000 p.s.i.g. and at a temperature in the range of 130 DEG  to 300 DEG C. and in the presence of an alkaline catalyst whose aqueous 0,1 molar solution has a pH of at least 9.  When the process is conducted batchwise, a temperature in the range of 130 DEG  to 275 DEG C. is used, and when operating on a continuous basis, the preferred temperature range is from 175 DEG  to 225 DEG C.  Suitable alkaline catalysts are the alkali metals and their carbonates, alkali and alkaline earth metal alkoxides, oxides, hydroxides, peroxides and cyanides, tertiary amines and quaternary ammonium bases.  The hydrocyanic acid may be introduced in the gaseous or liquid state or in a solution with methyl methacrylate.  A polymerization inhibitor, such as hydroquinone may be added to prevent polymerization of methyl methacrylate when the most active catalyst or highest temperatures are employed. The methyl b -cyanoisobutyrate may be used as a solvent for polymers or as an intermediate.

Abstract: 1362191 Television standards conversion INDEPENDENT BROADCASTING AUTHORITY 22 June 1971 [26 March 1970] 14976/70 Heading H4F A television line standard converter uses an interpolation control 401 to set four gain controls 402, 427, 453, 478 receiving signals from four consecutive lines, the resulting signals being added in an adder 444. For 625 to 405 line conversion the adder 444 provides 625 lines, 405 lines containing information and 220 being blank. Only the information carrying lines are written into stores 12, 15, 18, in sequence, the stores then being read at the line rate of 405 line output, the correct sync. signals being added in processor 115. The received signals may be converted to binary form at 207, reconversion to analogue form being carried out before application of the signals to processor 115. The binary signals may be processed in three channels, each channel operating at onethird the required total rate. Chrominance signals may also be converted to digital form as digital (R-Y) and (B-Y) signals and processed. The delay lines 3, 6, 9 and stores 12, 15, 18 may use shift registers. The 220 blank lines may alternatively be written into stores 12, 15, 18, these lines being omitted in the reading process. For 405 to 625 line conversion, 220 additional lines are supplied to stores 12, 15, 18 via an additional interpolator and set of gain controls.

Title: Television field-deflection circuit
IPC: H03K4/69
Filed: 1974-04-05
Abstract: 1466338 Vertical time-base circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 April 1974 [9 April 1973] 19133/74 Heading H3T The two halves of the vertical deflection coil of a time-base circuit are connected in series during the trace and in parallel during the retrace. The parallel connection enables a faster retrace at a given supply voltage. In Fig. 1 the coils are driven in series during the trace by a bridge type class B amplifier T1-T4 but during the retrace switch S1 is opened and switches S2-S4 are closed to connect the coils in parallel with the supply. In the full circuit of Fig. 4 the switch S4 is constituted by the transistor T1 in combination with the inverse parallel diode D5 and likewise switch S5 is constituted by T4 and D6. During the sweep the driver is controlled by an input saw-tooth voltage applied from terminal 6 to a differential amplifier T11, T12 which via T9 and T14 control the series connected driver transistors T1 and T2 and via T10 and T15 control the driver transistors T3 and T4. Negative feedback is applied from a current sensing resistor R2 via the differential pair T9, T10 to the driver transistors. In addition the junction of the deflector coil is maintained at half the supply voltage by feedback from the junction of equal resistors R10, R11 connected across the coils, feedback being supplied to a differential amplifier T16, T17 to control the constant current flowing in a differential amplifier T11, T12. The driver stages also include constant sources 7 and 8. During the retrace the input voltage V goes rapidly negative and as the output current cannot immediately follow, transistors T2 and T3 are cut off and T1 and T4 saturate. At the same time a pulse at 5 causes switches S2 and S3 to conduct and switch S1 to become non-conducting to effect the parallel connection of the deflection coils across the supply, the diodes in parallel with T1 and T4 serving to pass current when it reverses at the centre of the trace. In an alternative arrangement (Fig. 5, not shown), the right hand part of the driver circuit T3, T4 is omitted and the point Q is connected through earth.

The three-phase circuit breaker of Specification 1,011,422 is provided with a no-volt trip comprising an auxiliary electromagnet 14 normally energized by an interphase voltage to attract an armature (22) but releasing the armature when the voltage drops below a predetermined value so that a spring 45 causes an arm 35 on the armature to strike the armature 40 of the overload electromagnet of one phase of the breaker to release the contacts as usual through the common trip-bar (100).
