Abstract: 1,022,105. Making shoes. C. & J. CLARK Ltd. April 26, 1962 [May 16, 1961], No. 30119/63. Divided out of 17771/61. Heading A3B. The stresses and strains set up in shoe uppers are relaxed after lasting by a hot wetting treatment of the upper, whilst still on the last, and this treatment is preferably followed immediately by a heat-setting of the upper which also dries it out. The casted shoe uppers are treated, preferably, for from ¢ to 5 minutes with water in liquid, vapour, mist, steam or superheated steam form, and at temperatures up to 90‹C., e.g. 30‹-40‹C., or even 120‹C. Wetting or penetrating agents may be present, if desired, e.g. non-ionic or weakly ionic materials such as the dioctyl ester of Sodium Sulphosuccinic acid, condensation products of di-octyl phenol and ethylene oxide, or more strongly ionic substances, e.g. methyl didecyl benzyl trimethyl Ammonium Chloride among others. Subsequent heat-setting uses hot-air or dielectric, radiant, fluidized-bed, or infra-red heat the preferred procedure comprising heating the upper to a surface temperature of 100 to 160‹C, cooling for 60 seconds and then heating to 80 to 150‹C. Before slipping the upper may be cooled by a cold air stream. Grouped shoe components are loaded on to a track alongside paired right and left foot lasts and carried in 9 second through a temperature gradient and conditioner sequentially at stations along the track the following operations are then performed, stiffener insertion, pulling once, toe-lasting, seat casting, shank fitting, the pliability of the leather established by the pre-conditioning treatment of the uppers being preferably maintained by optional humidifying tunnels, shoe-bottom drying, pounding and roughening and sole-adhesive application. The stress relaxation conditioning is then effected in a humidifying tunnel and concurrent heat-setting on the upper and activation of the sole-adhesive effected in a further tunnel. Finally a sole is attached, the shoe is cooled in a tunnel, a heel is attached and the shoe slipped from the last.

Title: Trisazo dyestuffs
IPC: C09B31/22
Filed: 1949-11-25
Abstract: Trisazo dyestuffs are manufactured by coupling a diazotized amino-o-hydroxycarboxylic acid of the benzene series with a middle component of the benzene series which can be further diazotized, diazotizing the resulting aminomonoazo dyestuff and coupling with an aminohydroquinone dialkyl ether (these three components being free from sulphonic acid groups), and finally diazotizing the aminodisazo dyestuff obtained and coupling in alkaline medium with an aminonaphtholmonosulphonic acid or an N-alkyl or N-aryl derivative thereof.  Alternatively the aminomonoazo dyestuff is produced by coupling the diazo compound of an amine of the benzene series, containing a substituent convertible into an amino group, with an o-hydroxycarboxylic acid of the benzene series, and converting to an amino group the substituent so convertible, the process then being completed as before.  The products dye natural or regenerated cellulose fibres, and in some cases also wool, in deep navy blue to black shades which may be after-treated with chromium or copper salts. Examples describe the preparation of the following dyestuffs: (1) salicylic acid\sMp-nitraniline (reduced)-->aminohydroquinone diethyl ether-->(alkaline) 2 : 8 : 6- or 2 : 5 : 7-acid or the N-phenyl derivative of the latter; (2) o - cresotinic acid\sM1 - amino - 2 - methyl-4 - nitrobenzene (reduced)-->aminohydroquinone dimethyl ether-->(alkaline) 2 : 5 : 7-acid.  The following first and second components are specified for use in the first of the alternative processes above: aminosalicylic and aminocresotinic acids; aniline, toluidines, xylidines, anisidines, cresidines, aminohydroquinone dialkyl ethers, and chlorine substitution products of these amines.  The Specification as open to inspection under Sect. 91, comprises also the use of N-acyl derivatives of aminonaphtholsulphonic acids as end components, and specifies additionally 1-chloro-2-amino-5-naphthol-7-sulphonic acid and its N-alkyl, N-aryl and N-acyl derivatives.  In a further example, 4-amino-41-hydroxy-31-carboxyazobenzene is diazotized and coupled with aminohydroquinone dimethyl ether, and the product is diazotized and coupled with 2 : 8 : 6-acid or 1-chloro-2 : 5 : 7-acid.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1313608 Measuring peak voltage WESTERN ELECTRIC CO Inc 23 June 1970 [23 June 1969] 30340/70 Heading G1U [Also in Division H4] A light modulator comprises a fine grain ferro-electric ceramic plate 13 (average grain diameter # 2 Á), spaced electrodes 16A, 16B on one surface of the plate, and means for applying to the electrodes sequential first and second voltage pulses of opposite polarity, the pulse lights being such that the electric polarisation of the plate is alternately substantially zero ("ON") and substantially different from zero ("OFF"), with corresponding changes in its birefringence. The "OFF" state may have substantially saturated polarisation and the plate may act therein as a n#/2 plate, where n is integral and preferably even, e.g. when the plate is disposed between crossed polarisers 12, 17, as shown, for preventing light transmission. This particular arrangement gives a greater ON-OFF ratio since there is less light scatter in the "OFF" condition than in the "ON" condition. The plate may be "prepoled" in which case the "ON" voltage pulse is approximately one half of the "OFF" pulse in height, or it may be "superpoled" (a single annealing subsequent to the prepoling process) when the pulse heights will be equal. After being set to the zero polarisation state, the system of Fig.1, can be used to measure the maximum voltage in a waveform applied to electrode 16A, 16B as long as the components of the waveform correspond to a Fourier frequency of # 10<SP>3</SP> per second and the waveform is solely of one polarity. Reference has been directed by the Comptroller to Specification 1180529 and 1277109.

Abstract: 1,271,548. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 17 June, 1969 [18 June, 1968], No. 30512/69. Heading H4K. Calls to particular subscribers are diverted to nominated other stations, a call from a distant exchange to a subscriber having a call diversion facility in force causing the nominated directory number for diversion to be sent to the distant exchange. The facility is applied to the American No. 5 Cross-bar System as described in United States Specification 2,585,904. At a switching office B a subscriber with the appropriate class of service, and requiring a call diversion service, dials a request code which, if not followed by further digits within a period of ten seconds, results in clearing of the request code from originating register 6 and the connection of dial tone. The directory number to which calls are to be diverted is dialled into register 6 from which it is transferred to a memory 7 where it is recorded along with the identity of the subscriber requesting service. A cancellation code is dialled when the service is no longer wanted. A call incoming over trunk 4 from a distant office A is recognized, from the ringing code combination obtained from the directory number after translation in a number group circuit, as a call to a subscriber who may be subject to call diversion. Consequently a search is made in memory 7 for the wanted subscriber and, if call diversion is in force, a call transfer switching circuit 12 is seized and its identity is recorded in memory 7 along with the associated data. Marker 8 is thereupon instructed to set up a connection between incoming trunk 4 and appearance A of transfer circuit 12 which is then supplied with ringing tone. The tone is detected in circuit 12 which after a delay responds by reverting a signal tone to the originating office A the outgoing trunk 101 of which has a detector for such signal tone and responds by setting up a connection over an originating appearance Z to an originating register 103. Dial tone forwarded as a result of this connection is detected at office B by transfer circuit 12 which after a guard period puts a calling condition on its appearance C. The class-of-service attributed to appearance C causes marker 8 to effect connection to a sender 5 which is given the nominated directory number for diversion as obtained from memory 7 using the identity of the transfer circuit 12 to access the memory. On completion of its function the sender clears office B from the call. At the originating office A the register 103 uses the digits reverted from office B to set up a connection to the subscriber nominated for diversion who is assumed to be S3 at a third office C. Should the originating office A be such as to be unable to effect the diversion automatically no dial tone will be forwarded to office B which, instead of calling in sender 5, connects up an announcement machine 16 which is primed with the directory number for diversion from memory 7 and converts the number to a verbal announcement.

Title: Improvements relating to monoazo dyestuffs and their use
IPC: C09B43/30
Filed: 1963-08-01
Abstract: The invention comprises monoazo dyes free from acid water-solubilizing groups of formula <FORM:1009363/C4-C5/1> wherein A is a phenyl radical containing at least one electrophilic substituent in o- and/or p-position to the azo bond, B is hydrogen or an optionally substituted alkyl, cycloalkyl, aralkyl or aryl radical, R is an alkyl radical having at least 4 carbon atoms, a cycloalkyl radical or a possibly substituted aromatic radical and in which the -SO2OR group is isocyclically and atomatically bound.  The term "electrophilic substituent" is defined as a substituent having an attractive influence on the pair of electrons linking the substituent to the residue of the diazo component.  The dyes are prepared by the usual coupling process using appropriate reactants or by reacting the corresponding dyestuff sulphonyl halides with hydroxy compounds (R-OH).  The dyes may be used to colour printing inks and lacquers and to dye hydrophobic synthetic textile fibres, e.g. cellulose acetate or, preferably, aromatic polyester in orange shades.  The preparation of the dyes is described in examples.
