Title: Video signal recording and reproducing apparatus for stop motion picture
IPC: H04N5/91
Filed: 1973-04-06
Abstract: 1426916 Video signal recording HITACHI Ltd 6 April 1973 [7 April 1972] 16595/73 Heading H4F A video signal recording and reproducing apparatus in which a field is selected and recorded on a magnetic disc in response to a control signal and then repeatedly reproduced therefrom and displayed as a still picture until another field is similarly selected, recorded on the magnetic disc (the first field being erased) and repeatedly reproduced for display as a second still picture. Recording of each selected field is effected in response to a control signal having a period of one field which is generated in synchronism with the next occurring even (or odd) field vertical synchronizing signal after an instruction signal is generated, e.g. by operating a push button switch for stop motion (still) picture display, to thereby ensure that only even (or odd) fields are displayed as still pictures. A television receiver with this stop motion (still) facility may include two display tubes, one for the received video signal (motion picture display) and the other for the stop motion display of selected fields, or it may include only one display tube which is selectively switched between motion and stop motion display. The stop motion instruction display signal may be included in the received video signal.

Title: Improvements in electric resistances having a negative temperature coefficient
IPC: F28D7/08
Filed: 1935-06-07
Abstract: An electric resistance whose value at a temperature of 600 DEG  C is more than a hundred times smaller than its value at room temperature is made by sintering a mixture of ceramic material and silicon in an inert or reducing atmosphere, the quantity by weight of silicon being larger than that of the ceramic material. Substances such as ferrosilicon containing the requisite quantity of uncombined silicon may be used instead of pure silicon.  In an example, ferrosilicon containing 90 to 95 per cent silicon is made into a paste with clay and tragacanth, pressed into rods and sintered at 1300 DEG  C. in a reducing atmosphere.

Patent GB-670521-A (GB)
Title: Process for the oxidation of paraffinic hydrocarbons
Filed: 1949-06-27
Abstract: Paraffinic hydrocarbons are oxidized with nitrous gases and nitro-sulphuric acid containing less than 90 per cent, preferably 70-90 per cent, H2SO4.  Nitrous gases are gases containing NO and/or NO2 and nitro-sulphuric acid is defined as sulphuric acid containing dissolved NO and NO2. Oxidation is more intense than in prior art methods using nitrous gases alone or together with concentrated sulphuric or nitro-sulphuric acids and products are obtained with high acid but comparatively low ester numbers.  Maximum oxidation occurs with about 69 per cent H2SO4 when the acid number of the product is at a maximum.  The ester number increases with diminishing sulphuric acid strength because of an increase in nitro-paraffin by-products which react with the KOH used in the estimation of the ester number.  The latter may be separated, however, together with unchanged hydrocarbons by saponification of the products with alkali carbonates.  The fatty acids obtained from the aqueous layer of this saponification have practically no ester number.  On recycling the nitro compounds and unreacted hydrocarbons and again processing with acid of the preferred strength 80-90 per cent, no further rise in ester number occurs. Preferably fresh hydrocarbons are added to the recycled product. Water is also obtained as a by-product and conventional methods are used to maintain the required acid strength. If a constant concentration of nitro-sulphuric acid is maintained it may be constantly recycled.  A portion of the used gases may be continuously withdrawn and replaced by fresh nitrous gases to prevent a build-up of N2O and N2.  This results in loss of NO2 and to prevent this oxidation may be effected using the nitro-sulphuric acid alone-best results being obtained with a nitro-sulphuric acid containing 80-85 per cent H2SO4.  In this process recycled acid is treated with nitrous gases before reaction to make up for NO2 which has been reduced and lost as NO.  Again water formed is removed by usual methods including the passage of dry inert gases or those containing oxygen.  The latter gases, after condensation to remove water, may then be recycled through the sulphuric acid to free them from nitrous gases or through the reaction chamber.  Gases passed through the used acid should contain sufficient oxygen to convert any NO to NO2.  Hydrocarbons containing more than 10 carbon atoms are particularly usable, e.g. those obtained in the catalytic hydrogenation of CO.  Nitrous gases may be obtained by oxidizing ammonia.  In examples: (1) a diesel oil fraction is oxidized at 120 DEG  C. with nitrous gases and nitro-sulphuric acid containing 85 and 73 per cent sulphuric acid and about 10 per cent NO2 and in (2) paraffin wax is oxidized with nitro-sulphuric acid containing 83 per cent sulphuric acid.

Abstract: 703,469. Bottling. BRATBY & HINCHLIFFE, Ltd., and CLARKE, L. Oct. 20, 1952 [July 7, 1952], No. 16977/52. Class 125 (2)  In filling bottles and like containers with a flavouring liquid or " syrup" and gascharged water under counterpressure, the "syrup" is first introduced and then water is flowed in a slow, gentle way to form a covering layer acting as a buffer between the "syrup" and the main body of gas-charged water which is fed in at a greater speed than that of the covering water, the covering water being admitted before counterpressure is established. The covering water may or may not be gas-charged. The apparatus for supplying the covering water may be part of a "syruping" machine, an independent unit or part of the counterpressure filling machine. Any suitable means such as valves or restricted openings may be used for introducing covering water As shown in Fig. 1, the gascharged water reservoir 3 is provided with a vertically slidable filling nozzle 1 co-operating with a plug 2 and a sealing gasket 14. When a "syruped" bottle 5 is raised on an elevator, it  engages the lower end of the nozzle 1 which is raised. A narrow port 13 rises above the gasket 14 and the covering water passes into the bottle through channel 19, port 13, passage 10 and outlets 6. Further raising of the bottle causes a stop 9 to open a valve 8 to counterpressure the bottle through passage 15. A valve 11 then clears a stop 12 to allow a spring 18 to open the valve whereupon gas-charged water passes to the bottle through passages 22, 10 and outlets 6. After filling the bottle is lowered and valves 8, 11 close. When the port 13 passes beneath gasket 14, the bottle headspace is snifted to atmosphere through port 13 and channel 20. In a modification, the fluid flows are controlled by a rotated disc valve, the disc of which has the usual counterpressure, liquid and snift ports and, in addition, ports of restricted cross-section acting in the same way as the port 13 to admit the covering water. According to the Provisional Specification, the covering water may be admitted after counterpressure has been established. Reference has been directed by the Comptroller to Specification 588,719.

The disc 3 is carried by a shaft 7 rotated by the motor 2 and the pins 10 preferably pass through fibrous material carried in a peripheral groove to give resistance to their movement. The pins are moved to the right in Fig. 1, during " make " periods, by an incline 13 on the armature of an electromagnet 11, an incline 14 being provided to engage any displaced pins just before they reach the incline 13 to return them to the normal position. A series of contact springs 17 are mounted around a fixed member 15, some of the series being arranged so that contact is made by a displaced pin and others so that the contact is broken. The springs 17 are carried by brackets 16 secured in peripheral grooves in the member 15. A diagrammatic view of the pins, contacts and associated circuits is shown in Fig. 4, the series a, b, c of displaced pins corresponding to " make " periods and the series d, e to " break " periods. If the " make " periods are of the prescribed duration the displaced pins make contacts at several series of springs, only two 17<3>, 17<4>, of each series being shown, while the contacts 17<1>, 17<2> are broken only if the " break " periods are not of the prescribed duration. Thus, if the prescribed signal is received, a circuit will be made for flag indicator 21 which releases a contact 22 to complete the circuit of a bell 23.

Abstract: 624,549. Turbine plant. SULZER FRERES SOC. ANON. July 1, 1947, No. 17320. Convention date, July 30, 1946. [Class 110(iii)] [Also in Group XXXI] A vehicle driven by a gas turbine plant is provided with a steam boiler having its own firing means and intended primarily for heating purposes. The boiler can, however, be used temporarily to feed a steam turbine to assist the gas turbine plant when acceleration of the vehicle is required. A railway locomotive driven by a gas turbine plant consisting of a lowpressure compressor 2, a high-pressure compressor 3, a turbine 14 driving the compressors 2 and 3 and a useful output turbine 16 has a steam turbine 24, supplied with steam' from a boiler 19 used for heating the train, connected to the shaft of the turbine 14 so as to start the gas turbine and assist it during periods of acceleration. Part of the exhaust gases from the turbine 16 passes to atmosphere through the pipe 17 and part passes through the pipe 18 to act as combustion air in the combustion chamber 28 of the boiler 19. To start the plant, the induced draught fan 31 is used to suck air through the pipes 17 and 18 into the combustion chamber 28 and fuel burnt at the burner 27 is used to raise steam which is supplied to the turbine 24. The turbine 24 drives the compressors 2 and 3 and the turbine 14 until sufficient air is supplied by the compressors to allow the turbine 14 to drive them. The steam turbine 24 is then shut off. During this period the valve 41 is closed and the valve 42 open. When the turbine 14 and compressors 2, 3 are up to speed, the valve 42 is closed and the valve 41 opened. This allows the turbine 16 to accelerate and drive the wheels through the reversing gear 20, jack shaft 21, crank 22 and a coupling rod 23. The turbine 24 may also be used when accelerating the locomotive and may be coupled to the shaft of the gas turbine 16 in which case a further turbine for starting purposes is necessary.
