Patent GB-828850-A (GB)
Title: Process for preparing -Ï-amino-alkane-nitriles
IPC: C07C255/24
Filed: 1956-12-27
Abstract: o -Amino-alkane nitriles are produced by dehydration of the corresponding lactams in the presence of ammonia, the lactams in the vapour phase together with ammonia in excess of the equimolar proportion being passed at a temperature of 250-400 DEG  C. over a dehydration catalyst consisting of alumina and/or kaolin.  The process may be effected at atmospheric or reduced pressure, but usually about 0.5 atmospheres gauge is used to force the vapour through a reaction chamber filled with pellets of catalyst.  The contact time is generally less than 10 seconds, the preferred range being 1/4 to 1 1/2 sec. for activated alumina and 4-8 seconds for kaolin.  The ammonia may be in an excess ranging from as little as 5 to 15 moles. up to 100 moles. for every mole. of lactam.  The preferred temperature range is 325-375 DEG  C.  Preferably the ammonia and lactam vapours are mixed before passing over the catalyst by passing preheated ammonia through molten lactam or by passing a stream of molten lactam in countercurrent with gaseous ammonia through a heated vaporization chamber.

Title: Method of preparation of a semiconducting ternary structure
IPC: H01L21/00
Filed: 1974-09-10
Abstract: 1443492 Luminescent materials and uses thereof COMMISSARIAT A L'ENERGIE ATOMIQUE and AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 10 Sept 1974 [11 Sept 1973] 39496/74 Heading C4S [Also in Division H1] A semi-conductor body consisting at least in part of the alloy Mg x Zn 1-x Te is prepared by bombarding a wafer of ZnTe with Mg ions, and annealing the body so formed. To provide a substantially uniform alloy composition, at least to a desired depth, a series of implantations at different energies and dosages is carried out, e.g. as illustrated in Fig. 2, a first implantation is carried out at an energy of 100 KeV with a dosage of 1.75 x 10<SP>17</SP> atom/cm<SP>3</SP>, a second at 50 KeV and 4À12 x 10<SP>16</SP> atom/cm.<SP>3</SP> and a third at 20 KeV and 2À88 x 10<SP>16</SP> atom/cm.<SP>3</SP>. A surface region having a low concentration of Mg ions may be removed chemically or the implantations may be carried out through a deposited 200 to 300 Š metal film which is subsequently removed. The alloy may be used as a cathodoluminescent emitter in the blue region and to provide a three-colour emitter for a television tube, a layer 4 of ZnTe is deposited on a transparent substrate 2 (Fig. 5) and regions thereof are doped through windows in a mask 6 with oxygen to form red emitter zone 10, with P or Li to form green emitter zone 12 and with implanted Mg ions to form blue emitter zone 14. Since the undoped ZnTe is of P-type conductivity and at a certain value of x the alloy changes from P-type to N-type, a P-N heterojunction may be formed which emits in the blue region, or in the green region when donors and acceptors are introduced. A three colour matrix of e.1. diodes (Fig. 6) comprises ZnTe substrate 16 in which blue emitter 30 is formed by Mg implantation through window 20 in mask 18. Red emitter 26 and green emitter 28 are formed by deep doping with oxygen and P or Li respectively followed by shallower doping with B or Al to provide the N-P junctions.

[Also in Divisions B6 and C6-C7] Surfaces of articles melt-shaped from polyolefin materials are rendered more receptive to coating by admixing 0À005 to 0À50 weight per cent of a blowing agent which decomposes chemically on heating with a poly α-olefin material prior to melt-shaping at a temperature at which the blowing agent decomposes, and after melt-shaping treating the surfaces of the articles with an etching fluid prior to coating the surfaces. The polyolefin may be polypropylene or sequential copolymers of propylene with 5 to 20 weight per cent of ethylene. Specified blowing agents are azo-compounds, sulphohydrazides, N-nitroso compounds, azides and azines; which may be used with nucleating agents, e.g. zinc and calcium stearates, talc, whiting, chalk, baryta, clay, dolomite, diatomaceous earth, bentonite or rutile. The blowing agent may be dispersed throughout the polyolefin article or in the surface layers thereof. The etching fluid may be chromic acid or a mixture thereof with phosphoric acid, and the articles may subsequently be metallized by conventional methods. Materials intended for copper-plating may contain a stabilizer, e.g. benzotriazole, zinc sulphide, melamine, N- salicylidone hydrazide and oxanilide. In examples compositions comprising sequential propylene/ethylene copolymers and (1) azodicarbonamide or tetramethyl tetrazine or (2) azodicarbonamide are melt-shaped and etched with an etching fluid comprising sulphuric acid, phosphoric acid, chromium trioxide and water before metallizing.

Abstract: 1,069,930. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 20, 1965 [Oct. 16, 1964], No. 39957/65. Heading H4P. In a data transmission system binary signals are converted into multi-level signals by selecting a first group of signals from the input word and developing from them a succession of signals in a first channel, means for selecting ,a second group and for developing a succession of signals in a second channel, the amplitude of the output signal being determined by the level of the signal in the first channel, and the polarity by the level of the signal in the second channel. The circuit, Fig. 1 (not shown), comprises three triggers (ACT1-ACT3) connected as a shift register to which the input signals 4 are applied (Fig. 2, not shown). The pattern is shifted by clock pulses (1). The clock pulses also pass through trigger (ACT4) to produce double length clock pulses and in trigger (ACT5) they are doubled again. The output (5) from trigger (ACT 1) is inverted and gated with the output of trigger (ACT5). The resulting signal (13) is the second two pulses of the input word, inverted. The output of the trigger (ACT3) is inverted and gated with the output (3) of trigger (ACT5) inverted. This selects on lead 14 the same two bits inverted but delayed by half the word length. These two signals are combined in Or gate (3) and signal (15) consists of the second pair of bits in the input word, inverted and repeated. This signal is inverted and applied to the combining circuit. By similar gating arrangements the first two bits are selected and combined to stretch each to double length (8, Fig. 2). This signal is' applied to a first transition coder (CT1) and then to another (CT2). The output is delayed and inverted (RET1) and recombined to form a signal (12) which is used in the combining circuit (COM) to control the sign of the output signal 16. The output signals (16) consists of a large magnitude for " 1 " and a small magnitude for " 0." This sequence is repeated twice to represent the second pair of digits in the input word and the polarity of these signals indicates the first two digits.

Abstract: 955,749. Electric selectors. A. W. STANDAART. Nov. 8, 1961 [Nov. 8, 1960], No. 40072/61. Heading H1L. A cross-bar switch is used to set up the crossconnection field between the entry and exit hubs of a computer according to any given programme. The switch, which acts as a register for the programme, is shown in Fig. 4, and comprises flexible contacts, such as 11a and 12d, arranged in parallel groups selectively displaced by magnets, such as 11 and 12, against contacts, such as 26b and 29b, arranged in transversely disposed groups selectively displaceable by magnets such as 16 and 19. A particular connection is established, as for example between the contacts 11a and 26a, by first energizing magnet 11 to displace bar 51 carrying the group of contacts 11a to 11d which consequently engage their corresponding contacts 26a to 29a. The magnet 16 is now energized to withdraw the contact 26a laterally from the path of contact 11a which in consequence overthrows. Magnet 16 is now de-energized to place contact 26a in the return path of contact 11a so that when magnet 11 is de-energized contact 11a engages behind contact 26a and effects a single connection across the cross-connection field in which the contacts in common with 11a serve one entry hub and the contacts in common with 26a serve one exit hub. The contacts such as 11a are of platinum wire 59 with flattened portions 59<SP>1</SP> to give flexibility for displacement between their common electrically conductive attachment to mounting rods 60 and the actuating bars 51, and between the actuating bars and their contact making ends. The contacts such as 26a are of silver strip riveted to the operating bars 66 which also provide common electrical connections. A cross-connection field between the entry hubs 31 to 35 and the exit hubs 41 to 45 of a computer programme panel is shown in Fig. 1 where a switch of the kind shown in Fig. 4 provides a 5 x 5 array. Magnets 11 to 15 displace the rows of platinum contacts while magnets 16 to 20 displace the silver strip contacts. The connections across the field are set up by instructions on a punch tape 75 which starts a setting up sequence by energizing all magnets 16 to 20 which release any existing connections by withdrawing all silver strip contacts while magnets 11 to 15 are unenergized. The cross-connections are then set up one-by-one as brushes 82 connect the appropriate magnets to battery. The instructions for setting up the field may be read from magnetic tape or may be dialled to control suitable marking equipment for the magnets. The magnets may be replaced by suitable electro-pneumatic devices.

The energy beam used has a constant energy and frequency. The mask M may comprise a supporting layer of glass or plastics permeable to the energy beam from a carbon dioxide laser source and a layer of aluminium, magnesium or silver which includes areas a-f having progressively less reflectivity so that progressively deeper cavities are formed in the printing member D by the laser beam. The remainder of the mask layer comprises areas g which are fully reflecting so as to prevent the passage of the beam to the surface of the member D. The cross-section of the beam is a multiple of the surface area of the largest cavity to be formed. The mask M may alternatively be mounted directly on the member D. The printing member D may be in the form of a rotogravure cylinder which is rotated whilst the laser beam is moved along paths parallel to the cylinder axis. The cylinder may be scanned with two or more energy beams.
