Title: Electric distance relay
IPC: H02H7/30
Filed: 1934-01-09
Abstract: 414,963. Protective cut-out systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. Jan. 9, 1934, No. 812. Convention date, Jan. 10, 1933. [Class 38 (v).] A distance relay comprises a series of impedance-sensitive, instantaneously-acting members of different sensitivity, one or more of certain of which, when the impedance decreases below a critical value, start a timing device which successively closes connections between contacts operated by the said members, and a circuit for disconnecting the section or sections protected by the relay. Preferably the timing device is started over directional members actuated by the impedance - sensitive members. Associated with each phase of a three-phase relay are three elements 1, 2, 3, the balance arms 7, 8, 9 of which are pivoted at 4, 5, 6, are instantaneouslyacting, and carry contacts 10, 11, 12, respectively. The arms are acted upon by voltage elements 13, 14, 15 and current elements 16, 17, 18, in series with which are coils of a directional element 19 having contacts 22. The element 1 has the highest impedance setting and element 2 the lowest, element 3 being set to operate at an intermediate value. When an impedance value occurs in the line within the range of the relay, element 1 closes its contacts 10 to energize the coil 20 of relay 19 which if the direction of power flow is correct, closes contacts 22 to energize the coil 24 of the timing device. If the impedance is so small that element 2 closes contacts 11, the trip coil 28 of the breaker will be energized when contacts 25 close. If the impedance is not small enough to operate 2 'but operates 3, coil 28 will only be energized when contacts 26 close after threeto four-fifths of a second. If the impedance is not small enough to operate 2 or 3, the energization of 28 will only occur when contacts 27 close after about a second.

Title: Polymerisation of organic isocyanates
Inventor: TATE FRANCIS EDWARD GERVASE
IPC: C07D229/00
Filed: 1957-01-09
Abstract: Aryl isocyanates containing at least one isocyanate group preferably having no substituents ortho thereto are polymerized to the dimeric and/or trimeric form by contacting with a 3- and/or 4-substituted pyridine of such basicity that, when substituted in benzoic acid in the meta- or para-position respectively, said 3- and/or 4-substituent increases the pKa  value of the substituted benzoic acid, measured in water at 25 DEG  C. to greater than 4.35.  The process is preferably conducted at a temperature of between - 40 DEG  and 140 DEG  C. and in presence of an inert solvent. Specified pyridine catalysts are 4-alkoxy or -aryloxy pyridines (e.g. 4-ethoxypyridine), 3- and 4-dialkylamino pyridines (e.g. 3- and 4-dimethylaminopyridines), 3- and 4-alkylarylaminopyridines and pyridines containing a 3- or 4-substituent of the type: <FORM:0821158/IV (a)/1> where X represents an aliphatic chain with or without a hetero-link, such substituents being exemplified by 3- or 4-morpholino- or -piperidino-.  Between 0.005 to 15% of catalyst based on weight of isocyanate and temperatures between 0 DEG  and 100 DEG  C. facilitate the formation of the dimer, while between 0.05 to 15% of catalyst and 0 DEG  to 140 DEG  C. facilitates the formation of the trimer.  The polymerization may be terminated by addition of acyl halides or Friedel-Crafts catalysts such as boron trifluoride or its complexes in substantially equimolecular amounts with respect to the catalyst.  Specified isocyanates are phenyl isocyanate, para-chlorophenyl isocyanate, para-nitrophenyl isocyanate, 2 : 4 - toluenediisocyanate, 4 - chloro - 1 : 3 - phenylenediisocyanate, 2 - chloro - 1 : 4 - phenylenediisocyanate, para - tolyl isocyanate, 2 - nitro - 4 - isocyanatotoluene, anisole - 2 : 4 - diisocyanate, 3 - alkoxy - 1 : 4 - phenylene diisocyanates and 4-alkoxy-1 : 3-phenylene diisocyanates such as 4-methoxy-1 : 3-phenylene diisocyanate. The examples describe the preparation of N : N1-diphenyl uretedione, N : N1-bis - (4 - methyl - 3 - isocyanatophenyl) - uretedione, N : N1 : N11 - tris - (4 - methyl - 3 - isocyanatophenyl) - isocyanurate, N : N1 : N11 - tris - (para - tolyl) - isocyanurate, N : N1 : N11-tris-(para-nitrophenyl)-isocyanurate, N : N1 : N11-tris - (3 - nitro - 4 - methylphenyl) - isocyanurate and N : N1 : N11 - tris - (4 - methoxy - 3 - isocyanatophenyl) - isocyanurate.  4 - N - morpholinopyridine is prepared by reacting 4-chloropyridine-N-oxide with boiling morpholine in presence of hydrated copper sulphate.

Title: Telephone exchange
IPC: H04M3/36
Filed: 1975-03-24
Abstract: 1502415 Testing automatic exchanges PLESSEY CO Ltd 24 March 1975 [8 Jan 1974] 00896/74 Heading H4K A telecommunications exchange includes a quality of service monitor which operates an alarm if the quality of service provided by the exchange, i.e. the proportion of call attempts that are successfully completed, falls below a predetermined minimum standard. As shown counter MS is advanced one stage in respect of each call attempt, in response to a signal from central control c. MS has one hundred stages, and delivers an output signal when re-set to zero at the end of each cycle. A failure counter FP is advanced one stage in respect of any call which fails, and is re-set to zero by the output signal from MS. At stage 40 of FP a tapping is taken off to a prompt alarm p. Hence if the count in FP reaches 40 before the count in MS reaches 100, indicating a failure rate of at least 40%, a prompt alarm is actuated. The MS/FP combination monitors peak conditions, i.e. a small sample of 100 calls. Another counter combination AS/FA monitors average conditions, i.e. a sample of 1000 calls. AS is a ten stage counter and is stepped on one stage by the output from MS, while FA is advanced one stage in respect of any failed call. The AS/FA combination functions in the same manner as MS/FP, except that a failure rate of 2À5% in a sample of 1000 calls actuates a delayed alarm d.

Title: Method for the synthesis of penicillamine
IPC: C07D277/06
Filed: 1948-01-13
Abstract: Penicillamine hydrohalides (a -amino-b -mercapto-isovaleric acid hydrohalides) are prepared by refluxing a  - amino - b  - benzylmercaptoisovaleric acid with an aqueous hydrohalic acid, e.g. hydrobromic or hydriodic acid, preferably in an inert atmosphere such as nitrogen.  The benzyl halide and part of the water formed may be removed by fractional distillation during the reaction period and the resulting penicillamine hydrohalide may be recovered from the aqueous reaction solution by evaporating to dryness, digesting the product with a solvent and recovering the penicillamine hydrohalide by filtration.  The hydrobromide can also be purified by reacting with acetone to form 2 : 2 : 5 : 5 - tetramethyl - 4 - carboxy - thiazolidine hydrobromide which may be reconverted to the penicillamine hydrobromide by hydrolysis. In examples: (1) dl-a -amino-b -benzylmercapto - isovaleric acid is refluxed with aqueous hydrobromide hydrate which is purified by conversion to the dl-2 : 2 : 5 : 5-tetramethyl - 4 - carboxy - thiazolidine hydrobromide; (2) dl-a -amino-b -benzylmercapto-iso-valeric acid is refluxed with aqueous hydriodic acid; (3) d-a -amino-b -benzylmercapto-isovaleric acid is used in place of the dl-compound in the process of (1).  a -Amino-b -benzylmercapto-isovaleric acid is prepared by refluxing together hippuric acid, acetone, acetic anhydride and sodium acetate to form an azlactone which is treated with benzyl mercaptan in methanolic sodium methoxide.

Filed: 1989-10-26
Abstract: An apparatus for forming lather or soap foam for washing and/or shaving purposes comprises an actuation lever which simultaneously serves to drive a piston, a liquid soap-dosing pump and a membrane pump for generating compressed air. A perforated wall of a conduit or line enables blowing the compressed air into a dosed quantity of liquid soap located within a mixing chamber, to thereby form a coarse bubble lather or soap foam which subsequently is blown through a porous body, homogenized and compacted. Different embodiments of the apparatus can be realized and it is particularly suitable for use as a foot actuated structure and for producing hot lather for shaving. A preferred construction contains an intermittently operated heater for preheating the compressed air, to thereby accomplish a particularly effective generation of hot lather. The apparatus has the advantage of increased economy owing to its reduced consumption of liquid soap and can be faultlessly hygienically operated and is especially environmentally protective.

Title: Rotary anode
Inventor: MATSUMOTO TOSHIO
IPC: H01J35/10
Filed: 1982-01-06
Abstract: PURPOSE:To prevent generation of an interpositional slip at the fixing part of a target and a prop of an X-ray tube rotary anode. CONSTITUTION:In a junction part 9, platinum plating is performed on a target seat surface of a prop 4 and on an axial surface making contact with the inside of the target hole, in order to let the platinum diffuse into molybudenum of the target and the prop. In this case, when the target temperature exceeds 1,000 deg.C, a crack is generated in a crystaline interface of molybudenum of the target owing to platinum diffusion. However, when the emissivity of the target surface is rendered more than 0.6 by means of blackening treatment, and the like, the target temperature is suppressed to about 800 deg.C while the temperature at the platinum diffusion junction part between the target and the prop is also suppressed to 600-650 deg.C, thus generating no intergranular crack of molybudenum owing to platinum diffusion.

Title: Control carrier searching method
Inventor: HIRAYAMA TAKAYO
IPC: H04W72/08
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To reduce a time of a mobile station to search all carriers when information as to a substitute control carrier is not reported by using a total control carrier. SOLUTION: A carrier highly possible of being a control carrier is searched with priority and a carrier less possible of being a control carrier is not searched. For example, a carrier used by a relay station not to be captured as a control carrier is found out, since it is discriminated that a relay station to be captured does not use the carrier for the control carrier, the carrier is not searched. Furthermore, when a carrier used by a relay station for a communication carrier is found out, it is discriminated that any relay station highly possibly uses the carrier for the control carrier, and the block is searched with high priority.

Abstract: PURPOSE:To prevent ink in a piping from solidifying, by informing the fact that a power supply fed to an output unit is interrupted before the ink remaining in said piping has been recovered since the completion of the outputting opera tion of the ink is detected. CONSTITUTION:An ink supplied from an ink cylinder 3 is sprayed from a charge tunnel 7 to print a bar code. The postal matter printed with the bar codes are sorted out and collected in each areal box. After the sorting and collecting operation is finished, a power-off switch in an operator panel is turned ON. Consequently, relays KO1, KO2 are turned OFF to close contacts a, b. A control unit 1 outputs a power-off signal to an ink-jet printer. During the time when a power-off lamp is flickering, the pressure is supplied to an ink recovery vessel 15 by a compressor through a vacuum piping 17, whereby the atmospheric pressure in the recovery vessel 15 is reduced to a vacuum state. Accordingly, the ink which is not sprayed until the ink-jet printer is cut off the power is supplied from an ink sensor block 9 to a recovery piping 13, and the remaining ink is recovered to the ink recovery vessel 15.
