Title: Traffic monitor for data processing system
IPC: H04M3/36
Filed: 1973-04-16
Abstract: 1433413 Automatic exchange systems GTE AUTOMATIC ELECTRIC LABORATORIES Inc 16 April 1973 [1 May 1972] 18315/73 Heading H4K  A data processing system includes a plurality of peripheral units (register junctors) a memory including a corresponding plurality of storage blocks functioning as registers and being individually associated with the peripheral units, a common logic circuit sequentially associated with the registers in successive time slots of a TDM link and adapted in each time slot to read information from the associated register including process sequence (call) state information, to modify that information in accordance with information received from the peripheral units and to write the modified information into that register, a counting means adapted to be reset periodically and arranged to count the number of registers that indicate a particular process sequence state, a manually settable device into which a number can be set and a comparator which compares the counter output to the set number and sets a bi-stable upon coincidence. The invention is applied to the system shown in Fig. 1 of Specification 1,344,580. The memory is a magnetic core memory. The time allowed to initiate dialling, for interdigit pauses and response to certain tones depends on the number of registers in use. The embodiment described allows a maintenance man to set the time allowed during busy and slack periods separately and to set the busy/slack traffic level. This can be done separately for the incoming and local junctors. The common logic and memory may be duplicated, each portion dealing with half the junctors. As shown two counters 101, 102 are reset each clock cycle and count the number of incoming and local registers which are dealing with calls, this being indicated by the call state code G1 to G4 being not in the all zero idle state, and bit G1 to G4 producing an output at gate 120 which is gated to counter 101 or 102 depending on whether it is an incoming or local call. The values registered in counters 101, 102 are compared with the cut-in and cut-out traffic levels set in thumbwheel switches 152 and 154, 155 and 156 respectively. Latches 113 to 116 are each set when the associated counter level exceeds the corresponding thumbwheel setting. Latches 111 or 112 are set or reset when the associated pair of latches 113, 114 or 115, 116 are both set during a cycle or remain reset throughout a cycle and latch 110 is set to the state of latch 111 or latch 112 for each time slot depending on whether the particular call being dealt with is incoming or local.

Title: Improvements in processes for the manufacture of semi-conductive devices
IPC: C30B15/20
Filed: 1955-06-24
Abstract: 777,403. Semi-conductor devices. WESTERN ELECTRIC CO., Inc. June 24, 1955 [June 29. 1954], No. 18339/55. Class 37. A semi-conductor device is manufactured by wetting the end faces of a closely-spaced pair of electrodes with molten semi-conductor material so that material is supported between them by surface tension, which freezes to form the semi - conductor body. In one example, a pair of electrodes 11  and 12 supported by insulator 13 (Fig. 1B) are dipped into a melt of germanium 17 in an inert atmosphere such as helium, hydrogen or nitrogen. The electrode assembly is then withdrawn by means 22, and the germanium suspended between the electrodes allowed to cool. The electrodes may comprise donor or acceptor material to produce bodies with P and N regions, and may be made non-wettable except for their end regions by carbonizing, oxidizing, glazing or silicone coating. The body may be directionally cooled by means of a temperature gradient so that a monocrystal is formed, and the conductivity may be varied by utilizing the different segregation coefficient of various donor and acceptor material. The electrode with the smallest end may be withdrawn first from the melt to provide directional cooling. The electrodes may be graded in size to control the cooling process. Three or more electrodes may be utilized in one assembly and withdrawn together from the melt, to provide a transistor with, for example, NPN regions. A tetrode transistor is also described. The regions of N or P type conductivity may alternatively be produced by a thermal diffusion process applied after the body has cooled; mass production may be effected by arranging electrodes assemblies in multiple, or on a continuous band, for dipping into the melt. The semi-conductor material may consist of germanium, silicon, germanium-silicon alloy, or compounds of elements of Group III and Group V; the electrodes may consist of molybdenum, tantalum or tungsten, the acceptors of copper, thallium, indium, boron, aluminium or gallium and donors of antimony, phosphorus, lithium, or arsenic. Specifications 748,414 and 769,673, [Group XI], are referred to.

Title: Improvements in or relating to sheet registering devices in printing machines
IPC: B41F1/34
Filed: 1932-06-29
Abstract: 388,646. Feeding sheets. DEPENBROCK, W., 3, Heinrichstrasse, and SEITZWERKE GES., both in Kreuznach, Rhineland, Germany. June 29, 1932, No. 18361. [Class 100 (i).] Sheet-registering devices.-The means for registering sheets in printing-machines described in Specification 386,318, in which a predetermined marked impression space on the sheet is registered on the impression surface of the machine by the aid of luminous rays projected from below or above the impression surface, is modified in various ways. Instead of illuminating all of the area, the area may be defined by apertures e, e<1>, Fig. 2, so that only the boundaries of the area f are illuminated. Alternatively the area may be defined by angular apertures h, Fig. 4, or by small circular apertures at each corner of the area. In further modifications the non-printing parts of the impression surface may be illuminated, or when dealing with thin transparent papers the impression area may be printed in outline in colours which are discernible through the paper, or the impression plate may be formed of the exact size of the impression, or be formed with projections or recesses of the exact size. In further modifications, Figs. 7 and 10, masks n with apertures o corresponding to the impression space may be loosely suspended by means of pins p or by means of springs from the printing surface q, Fig. 7, in such a manner that the paper can be inserted below the mask ; or the masks may be pivoted to the impression plate a and automatically moved aside by the printing operation. To adjust the paper finely when narrow impressions are obtained rows of marking spots v, v<1>, Fig. 2, may be used, and printed lines on the paper registered therewith. In place of the masks n, stops of the same form as the slots e, e<1> Fig. 2, or h, Fig. 4, may be suspended above the impression plate a.

Title: Improvements in and relating to tampons, wads or the like, and materials therefor
Inventor: EDMUNDHEMSTED EDWARD CHARLES
IPC: A61L15/28
Filed: 1952-07-22
Abstract: A prophylactic or therapeutically active dressing comprises a lightly compressed mass of fibres or fibrous material which is wholly or completely soluble or dispersible in water and body fluids, impregnated with prophylactic or therapeutically active chemicals. Dressings e.g. tampons are formed from alginate or cellulose ether fibres impregnated with an oil and an emulsion or gel.  The oil used is either liquid paraffin or castor oil.  The gel includes a bactericidal agent e.g. water acidified by lactic acid, boric acid, citric acid, acetic acid or an emulsion of ricinoleic acid and also gum tragacanth, bassorin gum, agaragar or sodium alignate with or without the addition of glycerine. The acidulation is adjusted so that the pH value is between 3.5 and 4.5.  Prior to impregnation the gel and the oil may be emulsified with the assistance of an aicd-stable emulsifying agent e.g. Tegacid.  A band of fibrous material is passed through the emulsion and rolled to form a rope which is then twisted at intervals and cut into sections at each twist.  The cut sections are then chilled to 40 DEG -42 DEG F. and coated with an oil, e.g. petroleum oil, such as that known under the Registered Trade Mark "Vaseline".  The sections are finally coated with ammonium alginate or ethyl hydroxyethyl cellulose and dried.  In a modification a tampon is formed by encasing the emulsion in a soluble container of gelatin or alginate, wrapping a fibrous ribbon around it, cutting into lengths and finally coating each length as described above.  Alternatively each section may be coated by covering with a preformed film or sheet of material such as a cellulose ether known under the Registered Trade Mark "Modocoll M", using a wrapping machine.  In order that cellulose ether fibres may be matted or felted to the desired degree they are deposited from a swinging hammer mill, where they are teased or carded, on to a vibrating surface e.g. a conveyer belt to form a layer of the desired thickness and compactness.  The fibres may be impregnated with emulsion, before carding and felting, in a centrifuge at 100 DEG C. Tampons which are used either dry or wet may contain medicaments specially for the condition to be treated e.g. sulphathiazole, proflavine, ichthaminal, acetarsone, lactic acid, oestrogen, adrenalin, ephedrin, posterior pituitary extracts, vaso-dilators or oestrin compounds.
Patent GB-822500-A (GB)
Title: New colouration process for artificial fibres
Inventor: HADFIELD HARRY ROSE
Filed: 1956-06-15
Abstract: Artificial fibres of polyamides, polyurethanes, modified polyacrylonitrile or polyvinyl alcohol are dyed or printed with an aqueous suspension of a water-insoluble colouring matter (or dyestuff intermediate) containing a monohalogeno1:3:5-triazin-2-ylamino group. The dyestuff may be a nitro-, azo- or anthraquinone-dyestuff which is free from solubilizing groups.  In the case of a dyestuff intermediate, it may be a diazotizable amine or a coupling component which can be converted on the fibre into a dyestuff free from solubilizing groups.  Dyeing is effected from a bath which may contain dispersing agents such as sulphonated naphthaleneformaldehyde condensation products, sulphosuccinic acid esters, turkey red oil, alkylphenolethylene oxide condensates and soap, with or without protective colloids such as dextrin, British gum and water-soluble proteins, and electrolytes such as sodium chloride or sulphate at temperatures up to or above 100 DEG  C.  Dyeings on polyamide fibres may be after-treated with a hot aqueous solution of an alkali such as sodium carbonate, ammonia or ethanolamine. As applied to printing, the paste may contain thickeners such as methyl cellulose, starch, locust bean or crystal gum and sodium alginate, alkaline substances such as sodium bicarbonate, and the usual adjuvants such as urea, thiourea, thiodiglycol, methylated spirits, sodium metanitrobenzene sulphonates and aqueous emulsions of sulphonated oils.  The prints are fixed by steaming. Numerous examples are given and numerous dyestuffs are specified. The dyestuffs may be obtained by reacting an azo dyestuff such as an aminohydroxyazobenzene derivative, a benzene-azo-pyrazolone, a disazo compound or a diaminoazo compound, or a nitro dyestuff such as a 2:4-dinitro-31- (or 41-) amino-diphenylamine or other 4-substituted 2-nitro-41-aminodiphenyl amines containing as substituents an acyl, a sulphonamide, a trifluormethyl or an amide group, or an anthraquinone dyestuff such as 1-p-amino-anilinoanthraquinone or 4-hydroxy-1-b -aminoethylamino-anthraquinone, the dyestuff in each case being free of solubilizing groups and containing a primary or secondary amino group, with a 2:4 - dihalogeno - 1:3:5 - triazine such as 2:4 - dichloro - 6 - methoxy - (or - 6 - phenoxy-, or - 6 - ethoxy -, or - 6 - dimethylamino -, or 6 - phenylamino -, or - 6 - b  - hydroxyethyl - amino -, or - 6 - b  - cyanoethylamino -, or - 6 - phenyl -, or - 6 - methyl - 1:3:5 - triazine.  Numerous dyestuffs are listed.  The Provisional Specification refers also to the coloration of cellulose ester (including triacetate), and aromatic polyester fibres and natural silk and to the use of dyestuffs containing a dihalogeno1:3:5 - triazin - 2 - ylamino group.  When dyeing cellulose triacetate fibres swelling agents, such as diphenyl, dichlorobenzene, trichloroethylene and o- or p-phenyl phenol, may be added to the dyebath, and dyeings on triacetate or aromatic polyester fibres may be treated with a reducing agent before scouring.

Title: Improvements in and relating to steam traps
IPC: F16T1/48
Filed: 1933-07-04
Abstract: 404,554. Steam traps. COLLEY, C. J., 4475, West Pine Boulevard, St. Louis, Missouri, U.S.A. July 4, 1933, No. 18965. Convention date, Oct. 3, 1932. [Class 64 (ii).] The water vented by a steam trap of the intermittent dis charge type actuates a fluid pressure respon sive element or the discharge side of the trap which operates mechanism to count the discharges. The water from the trap entering at port 23 drives the piston 22 back so that it may escape through port 33 and actuates the counting-mechanism 13 by linkwork 36. Clearance is provided between the piston and its cylinder to allow the fluid leaking from the trap to escape without operating the counting- mechanism. Alternatively, a bye-pass tube may be provided for this purpose. The counting-mechanism may record and print the number of times water has been vented during successive predetermined intervals of time. The piston and cylinder arrangement may be replaced by a Bourdon tube, flexible diaphragm or bellows. A check valve is then placed in the discharging line to prevent changes in the pressure in this line, owing to the discharge of other traps into it, from operating the counting mechanism. The valve also serves to restrict the flow of the vented water and cause a sufficient pressure to be built up to actuate the counting means. A flap valve may also be used as an alternative pressure-responsive means.

Title: Improvements in or relating to the protection of electric rectifier systems
IPC: H02H7/127
Filed: 1939-06-30
Abstract: 530,198. Protective cut-out systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 30, 1939, No. 19044. Convention date, June 30, 1938. (Class 38 (v)] [Also in Group XXXV] An A.C. supply 10... 12 energizes a D.C. load circuit 13, 14 over rectifiers 18 &c. in parallel between the 6-phase secondaries of transformer 15. Shunts 33, 33<1> arranged in the cathode circuits are interconnected by the moving coil 35 of a centre-zero relay, the fixed contacts 41, 42 of which are respectively connected to the trip coils of breakers 47, 54 in the anode-leads 28, 31. Backfire in a rectifier causes the appropriate relay to deflect in the direction to trip only the faulty one, and preferably with a time-delay so as to allow other relays to extinguish the backfire by momentarily opening the ignition circuit. The latter includes the rectifier-electrode 26 and a gas-discharge device 55 having its anode connected to the anode-lead 28 or 31 and its grid connected to the appropriate secondary 59 of a transformer, the circuit being completed through the star-point, the + lead 13, rectifier 18, and contacts of a continuously-energized relay 65. The latter and the corresponding relay 77 of rectifier 19 have their coils short-circuited, on backfire, by contacts of relays 73, 74 energized in series from current transformer 70 in the supply line. When the backfire is thus extinguished, relays 65, 77 remake the ignition circuits and operation of the rectifiers is resumed. In a modification, Fig. 3 (not shown), the relay 65, when de-energized opens the grid circuit of device 55 and closes at back contacts the circuit to a negative-bias source, so blocking the device. The invention is also applicable, Fig. 4 (not shown), to a pair of six-anode rectifiers in parallel with a relay connected across the cathode circuits as in Fig. 1.
