IPC: H01R13/02
Filed: 1942-06-12
Abstract: 558,103. Two-part couplings. HARVEY, J. W. H., and PLESSEY CO., Ltd. June 12, 1942, No. 8082. [Class 38 (i)] In a multiple contact coupling, in order to ensure engagement of abutting contacts in spite of irregularities in the level of their surfaces, a helical spring 10 is attached to one contact of each pair to form a resilient abutment, the ends of the conductors 8 passing through projections 5 in an insulating block 3 while the conductors 11  emerge into sockets in the block 4 into which the projections 5 fit to isolate the contacts. The outer casings 1, 2 are drawn together by a screw ring 12. The ends of the cables 8, 11 are threaded through ferrules and the turned-back ends secured by thimbles 7, 9. The thimbles 9 also secure the springs 10 by engagement with a single convolution of reduced diameter. The contacts are arranged in a circle but one lying eccentrically within the circle, see Fig. 4, prevents incorrect coupling.

Title: Manufacture of alkylated or cyclo-alkylated arylsulphonic acids
IPC: C07C303/22
Filed: 1927-03-25
Abstract: 268,375. I. G. Farbenindustrie Akt.- Ges. March 27, 1926, [Convention date]. Addition to 250,241. Sulphonic acids.-The process described in the parent Specification, in which an aromatic hydrocarbon is treated with a higher aliphatic or alicyclic alcohol and chlorsulphonic acid, is modified by replacing the aromatic hydrocarbon by a sulphonic acid thereof, which becomes further sulphonated. Care is taken that the sulphonic acid is used in a state as anhydrous as possible, which can best be attained by preparing it by means of chlorsulphonic acid, or if sulphuric acid is used the water is removed by heat &c. By this means naphthalene derivatives simultaneously sulphonated in the a- and #-position may be obtained. In an example, chlorosulphonic acid is added to naphthalene at 135-145‹ C. and the mixture is stirred for some time. On cooling to 70‹ C., butyl alcohol and chlorosulphonic acid is run in, and after a time a further quantity of chlorosulphonic acid. When the product has become entirely soluble in water, it is worked up into its dry sodium salt. The product can be used as a wetting agent, an emulsifying agent or the like.

Title: Magnetic thin film storage device
IPC: G11C11/14
Filed: 1976-03-03
Abstract: 1530404 Magnetic storage arrangements BASF AG 3 March 1976 [4 March 1975] 08450/76 Heading H3B In a magnetic domain propagating arrangement in which domain paths are provided in a thin layer of high coercivity material by channels K1-K8, Fig. 1a, of a lower coercivity material, the channels are arranged in groups with each group terminated by a respective read out area A1-A8 of lower coercivity material. The thin layer is formed on a substrate and is stacked in register with three further plates, Figs. 2a, 3a, 4a, on which operational control and read out conductors are provided, interconnections between the plates being made by plating through aligned holes. In use the eight bits of a data word are distributed in like positions over the eight channel groups, and successive words are similarly distributed but each time using a different channel in each group. Domains representing a data word are formed in the channels by pulsing a conductor 66, 67, Fig. 4a, and by pulsing a conductor in a corresponding position in each of eight groups of conductors B1-B8, Fig. 2a. At the same time conductors C1-C8, Fig. 3a, are selectively pulsed to determine whether domains representing a logic "1" are to be produced in the respective channels, the absence of a domain being used to denote a logic "0". The domains in the channels are advanced by alternately energizing positionally interlaced conductors B9 and C9, Figs. 2a and 3a, respectively. At the ends of the channels, conductor loops B11-B18 extending over the read areas A1-A8, Fig. 2a, are used for inductive read out and may be coupled to the conductors C1-C8 for data recirculation. Entry to the read out areas involves further areas H1-H8, Fig. 1a, of the lower coercivity material, and is controlled by selectively energizing conductors 30-49 and C11-C18, the latter conductors being used to select the channels from which data is to be read. Erasure of the domains in the areas H1-R8 and A1-A8 following read out is effected by negative currents in all the conductors 30-49.

Filed: 1925-04-01
Abstract: 231,868. Rosien, C. F., (Assisnees of National Cash Register Co.). April 2, 1924, [Convention date]. Ink - ribbon mechanism.-In automatic feedreversing mechanism for ink ribbon employed in cash registers, calculating-machines, &c., reversal is positively effected by devices cooperating with the spool-flanges. The ink ribbon 30 is attached to spools 31, 32 provided with ratchet-wheels 33 co-operating with pawls 39, 40 mounted on a link 38 carried by rocking arms 35, 37, the arm 37 being connected by a link 46 to a periodically-operated lever 47. Each spool is formed in one flange 55 with a gap 54 normally bridged by a plate 51 which is pivoted at 52 to the flange and has a lug 56, Fig. 5, entering a depression in the spool-hub 31. Spring- urged levers 49, 50, pivoted on a stud 61, have lugs 53 resting on the flanges 55, and lugs 57, 57<1> co-operating with fingers 58, 58<1> on a link 59 connecting rocking arms 60 on the link 38. The ends of the arms 60 engage pins 71 on the pawls. When the ink ribbon has been wound off either spool, for instance the spool 31, the plate 51 is released and the lug 53 of the lever 49 can enter the gap 54, the lug 57 being thereby brought into the path of the finger 58 so that at the next operation of the lever 47 the arms 60 are rocked and the pawls 39, 40 are moved into and out of operative position. The spools are detachable from the ratchet-wheels, coupling being effected by engagement of lugs on the raitchet-wheels with openings 42, Fig. 5, in the spools. When the spools are inserted, the spool-flanges engage inclines on the lugs 53 and raise the levers 49, 50.

Title: Electro-optical displacement sensing
IPC: C23C14/24
Filed: 1970-02-24
Abstract: 1294234 Photo-electric measurement of displacement UNITED AIRCRAFT CORP 24 Feb 1970 [13 March 1969] 8855/70 Heading G1A [Also in Divisions G3 and C7] The surface of the molten source pool 20 of a vacuum vapour deposition system is maintained at a constant height under the control of a photoelectric level sensing arrangement. Monochromatic light from a helium-neon gas laser 28 is focused into a spot on the surface 20 by lens and aperture system 32, 34, 44. The large focal length of lens 34 and small aperture 44 provide a large depth of field and allow for changes in surface 20 height and ensure greater separation of these elements from the pool so minimizing deposition of condensate thereon. An inert gas flow through aperture 42 also prevents such deposition. A similar optical system 62, 50, 52 receives the reflected beam. At the downstream conjugate focus of lens systems 50, 52 is located a pair of silicon photo-diodes 64, receiving reflected light which may be a continuous beam or periodic flashes; occurring during rippling of the surface 20. A wavelength filter 70 restricts received radiation to those wavelengths emitted by the laser. The photodiodes are connected in a wheatstone bridge circuit, unbalance of which indicates deviation from the desired level and causes actuator or motor 24 to move the ingot 16 as required to retain balance. The preferred angle of incidence of the beam is in the range 30-80 degrees and is preferably 70 degrees. A viewing screen is provided at 76.

Filed: 1951-04-16
Abstract: 711,702. Photographic diazotype layers for relief and photomechanical procedure. KODAK, Ltd. April 15, 1952 [April 16, 1951]. No. 8864/51. Class 98(2) A support having a layer of gelatin containing a diazo compound of such nature that, after exposure of the layer to light exposed portions of the layer can be removed by washing in water at pH below 2.5, such as diazotized wherein R and R<SP>1</SP> represent hydrogen, alkyl or aryl groups, D and D' represent paraphenylene radicals which may contain alkyl groups, and n has a value of 0 or 1, is exposed imagewise and washed at a pH of less than 2.5 to remove exposed parts of the layer. Either the washing water or the layer itself may contain acid to give. the required pH. Preferably the gelatin contains a hardening agent, and in this case the layers are included within the terms of the invention. The support may be glass, metal, film or paper with a hydrophobic subbing layer, whereby, with the gelatin layer being hydrophilic, the product constitutes a lithographic printing plate. The diazo compounds may be derivatives of p-phenylenediamine, N-alkyl-pphenylenediamine, N : N-dialkyl-p-phenylenediamine, N-aryl-p-phenylenediamine, 4 4-diaminodiphenylmethane or N-alkyl- or N : N-dialkylderivatives of the latter. A hardener such as chrome alum or formaldehyde may be included in the layer and a comminuted solid such as baryta, in amount up to 10 times the weight of the gelatin, may be included as well. Hydrochloric, citric, acetic or oxalic acid may be used to produce the desired pH. In Example 1 a glass plate is coated with a solution of gelatin and chrome alum, dried, bathed in a diazo solution of 3-methyl-4-aminodiethylaniline, hydrochloric acid and sodium nitrate, dried, exposed under a line negative and washed in running water to leave unexposed portions as a relief image on the glass plate. In Example 2 a cellulose nitrate subbed paper base is provided with a gelatin-baryta-chrome alum layer, sensitized as in example 1 and exposed and developed similarly to produce a lithographic plate. In Example 3 tetrazotized 4:4'-diamine-diphenylmethane at pH 0.6 is used as sensitizer, or may be used at pH 7, in which case acidified hydrogen peroxide is used as washing water. Example 4 indicates the use of formaldehyde as hardener; and Example 5 the production of a negative relief image from a negative silver half-tone by diazotization, exposure and acid treatment, the silver half-tone portions preventing exposure of underlying gelatin. Silk screen stencils are referred to.
