Title: Control arrangement for time-division switching network
IPC: H04Q11/06
Filed: 1974-06-06
Abstract: 1447713 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 6 June 1974 [13 June 1973] 25090/74 Heading H4K A telecommunication system includes a time division switching network comprising two identical branches, each sample is duplicated and sent over both branches, a binary code characteristic of each sample as input to the network is derived, transmitted in binary form through the network with the sample and compared with a fresh derivation of that characteristic produced at the output end of the network. Fig. 1 shows a time space time network divided into two parallel sections shown above and below a clock unit H. Incoming j unction OJE for example is connected to both sections and each serial P.C.M. sample is (in each section) converted to parallel form 1 to n in a register arrangement OMJ and a parity bit is generated on an additional parallel wire P by a bi-stable OAJ. The parallel codes are supermultiplexed at SM1, intermediately stored at MPE, read-out under control of an address store MAE and transmitted via a space switching stage S to a time stage TS. The time stages TS are generally organized in a manner similar to the time stage TE but include parallel to serial converters ORC and associated bi-stables OAJS which are initially set by the transmitted parity bit and check that outputs of the converters ORC are correct. If this is not the case a signal is transmitted to the common control UC which determines which of two paths is to be used and controls a correspond output switch such as OX1 accordingly.

Title: Improvements in or relating to the vulcanization of rubber
IPC: C08K5/00
Filed: 1931-09-11
Abstract: The prevulcanization of rubber mixes containing a mercaptothiazole accelerator is prevented by the addition to the mix of a small quantity, e.g. 5-500 per cent by weight of the accelerator, of a substituted benzoic acid added separately or in admixture with the accelerator The ortho substitution products, such as o-hydroxy-, o-chloro-, o-methyl-, o-amino-benzoic acids, or the ferrous calcium, cadmium, magnesium, barium, lead, aluminium, or zinc salts of such acids are preferred.  Meta and para substitution products may also be used, but are less effective.  If the metal salts are used the results are comparable with those obtained from the free acids if the salt is used in such quantity as to contain an equivalent amount of acid radical. Examples are given showing the results of the addition of varying amounts of inhibitor under varying conditions.

Title: Improvements in or relating to the purification of oil or other liquids
IPC: C10M175/00
Filed: 1937-09-22
Abstract: 508,099. Purifying or reconditioning oils, fats, waxes; breaking emulsions. ATKIEBOLAGET SEPARATOR. Sept. 22, 1937, No. 25704. Void. Convention date, Sept. 25, 1936. [Class 91] Oit-water emulsions are broken and oils, liquefied fats or waxes, or other liquids are freed from colloidal solids and other impurities by adding water unless sufficient is already present, heating to over 100‹ C. under the pressure necessary to prevent substantial vaporization of the water, and centrifuging or allowing the coagulated water and impurities to settle out while maintaining atmospheric or other temperature and pressure conditions preventing substantial vaporization. The water may contain acids, alkalies, or salts ; and the treated oil may be percolated through adsorbent. The process is especially applicable to new or used oils containing colloidal carbon, e.g. used lubricating oil of internal combustion engines, quenching oils used in the tempering of steel, and oils used for high temperature distribution of heat; it may be applied to palm oil used in the manufacture of tinplate or as lubricant in the cold rolling of metals. In an example, 100 vol. of Diesel crank-case oil and 5-50 vol. of water from tanlis a, p are mixed in a pump c and forced through a heat exchanger d, a pipe r, and a heating coil s to a float chamber h, a pipe t passing through the heat exchanger d, a cooler u, a pressure-reducing valve x, and a centrifuge o. The oil is raised in temperature to 150-200‹ C. under a pressure of 100-150 lb., and reduced to below 100‹ C. or the flash point, whichever is lower, at atmospheric pressure at the valve k; but the pressure and temperature may be maintained, or only somewhat correspondingly reduced, and the centrifuging effected hot under pressure. The pressure-reducing valve x is such that pressure reduction is effected without atomization, and is controlled from the chamber by a float j, levers and links j<1>, j<2>, j<3>, and a brake shoe w<1> pressing on a brake wheel w of a liquid motor k; should the pressure in the chamber h rise above that just preventing boiling at the temperature of the oil-water mixture therein, vapours in the chamber condense, the liquid and float j rise, and no release the brake w and allow cooled liquid to escape through the valve x; should the pressure in the chamber h be lower than that required vapour is formed, the float falls, and the brake is tightened and reduces the flow through the valve x.

[Also in Division G1] Photo-electric reading apparatus for reading information contained in zones arranged in parallel rows on a medium 8, comprises a photocell 13 for each row on one side of the medium and on the other side, a light source 1, a condenser lens 4 and for each cell, a lens 7 arranged to produce a point image on the medium. The cells 13 and lenses 7 are arranged in a honeycomb like grid, as in Fig. 3, with each photocell area centred on its respective row 82 of zones. This arrangement allows the reading of many more items of information than a simple linear array of photo-cells. The medium may be 35 mm. photographic film, the presence or absence of an item of information, being represented by the degree of contrast of a zone with the background (transparency of the film). Also, punched tape may be read. The medium may be fixed or moving. The light source may be a lamp, as shown, having a minimally laterally extending filament, so that a point image can be obtained, or a pulsed discharge lamp. The detectors are photoresistive cells. If an electroluminescent device (e.g. gallium arsenide diode), emitting infra-red, is used, silicon photodiode detectors may be used.

Title: Improvements in or relating to method and machine for making a nut blank
IPC: B21K1/70
Filed: 1945-10-04
Abstract: 613,034. Forging nuts. WATERBURY PARREL FOUNDRY & MACHINE CO. Oct. 4, 1945, No. 25799. Convention date, Dec. 19, 1944. [Class 83 (iv)] Dies ; Shearing-adjuncts.-A method of making a nut blank comprises forming in one end of a solid workpiece a recess surrounded by a cylindrical skirt extending along a substantial portion of the workpiece, forming polygonal outer faces adjacent the other end of the workpiece, decreasing the thickness of the web formed by said recess, and piercing an opening in the workpiece by removing the web. At the second station, a blank which has been sheared from a bar 1 by a tool 17 at the first station is pressed into a die 20 by a punch 26. This squares up the blank and cones the inner edge. At the third station, the blank is held by a pin 43 and is then forced by a punch 39 having a conical recess 41 into a die 30 formed with an opening which is flared towards its inner end. As the punch and die advance, the blank engages the conical end of a tool 35 so that the work is shaped as shown in Fig. 6. As the punch 39 is withdrawn, a knock-out pin advances the tool 35 to eject the blank, this operation also serving to draw the flared inner skirt portion to cylindrical form as shown in Fig. 7. An inner die 62 at the fourth station has an annular recess around a tool 63 to receive the skirt portion of the blank while an outer die 61 has a hexagonal recess into which the lower or outer portion of the work is upset by a punch 54 which also forms a conical recess 72, Fig. 8, in the outer end of the work, leaving a web 74 to be removed by a punch 75 at the fifth station. Here, the die 76 is so shaped that the skirt at the inner end of the work is brought to cylindrical form internally and tapering inwardly from the hexagonal portion, externally. The severed web is retained between two inwardly projecting pins projecting through slots 89 in the ejector sleeve 82, Fig. 3. As further portions are punched out of succeeding blanks, they pile up above the supporting pins and the upper ones are discharged through the openings 90, 91, 92 and 93. If the finished nut blank should be removed from the die 76 by the punch 75, it will be stripped therefrom by a stripping sleeve 104. The nut blanks are carried from the fifth station by transfer fingers 106 from which they are removed by a knockout pin 107 and drop into a discharge shoot 112.

Abstract: 797,095. Cathode materials and processing. STANDARD TELEPHONES & CABLES, Ltd. Aug. 24, 1956 [Aug. 25, 1955], No. 25959/56. Drawings to Specification. Class 39(1). An oxide cathode comprises a nickel core coated with an alkaline earth emissive material, the nickel core containing as impurities one or more of the metals aluminium, magnesium or tungsten which act as activating agents and also reduce the resistance of the interface between the nickel and the coating, the concentration of at least one of the impurities in a cross-section of the core material being a minimum in the region of the core adjacent the coating. In this manner it is ensured that after a long operating time a large quantity of metallic additions migrate into the interface, to reduce its resistance, without the occurrence of excessively high evaporation during the manufacture and early operating time of the valve. The concentration of the impurities may be a maximum at the centre of the core cross-section and a minimum at each surface. The core may contain tungsten and at least one other impurity, the concentration of tungsten being uniform across the cross-section. The core may be formed by placing pieces of sheet metal containing the required amounts of impurities upon one another and combining them into one layer by rolling or drawing.

[Class 38 (iv)] Electromotive force.- The output voltage of a high frequency valve oscillator V1 is maintained constant by a thermionic diode or equivalent V2 the cathode of which is heated in accordance with the regulated voltage and the anode circuit of which comprises a resistance R which becomes the seat of compensating voltages and is included in the anode or grid circuit of the valve oscillator. The filament of the valve V2 and the output circuit the voltage of which is controlled may be inductively coupled to the anode circuit and the oscillator as shown in the Figure. In a modification the coupling coil feeds a Wheatstone bridge, one arm of which includes the filament of the valve V2, and the output circuit is connected across the other diagonal of the bridge ; a further regulating action due to the change in resistance of the filament is thus obtained. Anode current may heat a coil surrounding resistance in the filament circuit. In a further modification the anode circuit of the valve V2 is coupled to the oscillator anode circuit in series with a resistance across which the ouput circuit is connected; thus an additional regulation due to the changing impedance of the valve V2 is obtained. In a further arrangement the output is connected across a resistance in the filament circuit of the valve V2.
