Inventor: CLARKE WALTER WILSON HUGH
IPC: H01P1/24
Filed: 1950-12-05
Abstract: 691,012. Impedance networks. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Dec. 4, 1951 [Dec. 5, 1950], No. 29779/50. Class 40 (viii). An electric network consists of lumped components 18, 19, 20, 21 and 22, mounted in a case 5 of coaxial form, which acts as a shield .and is connected to the end of a coaxial line 4. As shown, the outer and inner parts of the casing may include tapered sections 1 and 13 to match the impedance of the case to the cable. The outer end of the casing is closed by a conducting plate 12 and the inner member 14 of the casing is supported by an insulating plate 6. The lumped components of the network are shown in shunt connection with the coaxial cable but series connected elements may be connected in gaps formed in inner conductor 14, as indicated at 33. For adjustment a movable condenser plate 27 co-operating with the end of member 14, and a resistor 30, are operated by external knobs 29 and 32 respectively.

Title: Improvements in taps, valves and the like
IPC: F16K3/26
Filed: 1922-11-01
Abstract: 210,530. Shaw, H. S. Hele-, and Livsey, H. Nov. 1, 1922. Seats, valve members, and faces; actuating mechanism; leakage, stopping; materials, special. -In a fluid tap, an axially-movable plug moves into a packing ring of flexible material to shut off the fluid. The flexible packing ring or seating member 5 is held in the casing 6 by a screwed nozzle 72 and a similar ring 50 is secured by a cap 67. The plug 25 is provided with a screw thread 27 co-operating with a fixed pin 40, and having a circular groove 30 at each end to prevent jamming at either end of the travel. The tapered end 250 of the plug is grooved at 24, extending into the cylindrical portion. Fluid tightness is ensured by the pressure of the fluid around the flexible members 5 and 50. In a modification, Fig. 3, the casing 6 is of rubber composition or similar material, and the spindle is plain. The plug 25 may be of porcelain, and may have a shoulder 23 to limit its movement. In another modification, Fig. 5, the rings 5, 50 are formed of rubber tube, and are held in position by conical rings 74 and the screwed members 72, 67. In another modification, the rings 5, 50 are coaxial with the inlet instead of the outlet, and the free end of the seating ring 5 extends away from instead of towards the plug. In another example, Fig. 9, the plug has upper and lower plain portions 2, 25 separated by a reduced portion 26. The inner end of the portion 25 is grooved at 24. The inlet and outlet 7, 73 are coaxial, and the fluid pressures are balanced. The flexible seating member 5 has free edges extending in opposite directions, so as to be self-sealing whichever end of the tap is used as the inlet.

Abstract: A mixture of isomeric bis-chlorobutenyl sulphides having the formul Cl.CH2CH=CH.CH2-S-CH2.CH=CH.CH2Cl and CH2=CH-CHCl-CH2-S-CH2.CHClCH=CH2 prepared by reacting two or more moles. of butadiene and one mole. of sulphur dichloride (see Group IV (b)) may be reacted with an inorganic cyanide to yield a dinitrile which on hydrolysis yields a dicarboxylic acid which may be used in the manufacture of alkyd resins, or the mixture can be reacted with an aqueous solution of an alkali carbonate to yield a mixture of the isomeric glycols which can react with polycarboxylic acids including the above dicarboxylic acids to yield linear polyesters or alkyd resins. The mixture of isomers may also be converted to a mixture of isomeric diamines which can be reacted with dicarboxylic acids including the one formed as above to form polyamides.ALSO:A mixture of isomeric bis-chlorobutenyl sulphides having the formul ClCH2CH=CH.CH2-S-CH2.CH=CHCH2Cl and CH2=CH-CHCl-CH2-S-CH2CHClCH=CH2 is prepared by reacting two or more moles. of butadiene and one mole of sulphur dichloride at a temperature from 0 DEG  to 5 DEG  C.  If desired, superatmospheric pressure, e.g. pressures up to 100 pounds per square inch, may be used.  It is preferred to effect the process in the presence of a solvent, particularly carbon tetrachloride.  The isomeric products may be separated by fractional distillation.  The mixture of isomers on reacting with an inorganic cyanide appears to yield only one dinitrile which may be hydrolysed to a dicarboxylic acid.  The mixture of isomers can be reacted with an aqueous solution of an alkali carbonate to yield a mixture of the isomeric glycols or may be converted to a mixture of isomeric diamines and the dicarboxylic acid, glycols and diamines can be used to form polyesters and polyamides (see Group IV (a)).  An example is given in which the mixture of isomers is obtained by carrying out the reaction in the presence of carbon tetrachloride and at 20-25 DEG  C. Specification 591,714 is referred to.

Filed: 1972-06-28
Abstract: 1395603 Projection welding FORD MOTOR CO Ltd 28 June 1972 30225/72 Heading B3R In a method of electrical resistance projection welding wherein the quality of weld is monitored, a projection 15 is formed on one workpiece, e.g. a carburettor throttle lever 11, and brought into contact with a second workpiece, e.g. spigot 13 of throttle shaft 10. Welding current is passed between electrodes 16 and 19 and pressure is applied between electrode 19 and base 17 with the interposition of insulator 18. The rate of collapse of the projection is measured while the current is passed and the weld is rejected if the rate is less than a pre-determined value obtained for example by comparing the collapse rates with final weld strength of similar workpieces. Preferably, the weld is also rejected if the rate of collapse is more than an upper predetermined value. An apparatus suitable for monitoring the rate of collapse by detecting the variation of electrode separation over a fixed period of time is a modified known spot weld quality monitor a published description of which is referred to.

Title: Improvements relating to baked products
Inventor: GEORGE WALTER FRANK CROSS
IPC: A21D13/06
Filed: 1954-08-22
Abstract: Long keeping bakery products of low starch content are made without fermentation from wheat gluten supplemented with wheat germ and wheat bran containing a high proportion of the aleurone and other inner layers.  The products are made by aerating a mixture of wet gluten, flour, the germ, the bran, and salt by kneading, dividing the aerated mixture into portions, baking the portions and then drying them. Baking may be to 20-27 per cent moisture, and drying to 10-12 per cent moisture.  The final drying may be effected by prolonged heating in a warm chamber, by heating in a turbulent stream of warm air, or by infra-red or high-frequency electric heating.  According to an example, 100 parts of a gluten preparation of 66 per cent water content, made by washing starch from wheat flour, is mixed with 26 parts of flour, 5 1/4 parts of wheat germ, 4 parts of the bran and 1 1/2 of salt.

In a television receiver the end wall 11 of cathode-ray tube 10, Fig. 3, incorporates a neutral density light filter which transmits between 45% and 55% of the light from the fluorescent screen, the cathode-ray tube being located within a cabinet, the front of which is closed by a screen 7 which constitutes a neutral density light filter which transmits between 20% and 30% of the light received from the cathode-ray tube. The arrangement is such that the end wall of the cathode-ray tube is virtually invisible when the receiver is not in use, i.e. when no visible light is emitted from the fluorescent screen of the tube. The screen preferably extends over the whole of one side of the receiver cabinet and may be constructed to serve as an implosion screen. When not in use screen 7 will appear black since ambient light reflected from end wall 11 passes twice through screen 7 and is thus attenuated.
