Title: Process of making pigments
IPC: C01G9/08
Filed: 1935-12-27
Abstract: <PICT:0454343/III/1> <PICT:0454343/III/2> Pigment forming metals such as zinc, cadmium, mercury or lead are vaporized, and the vapours reacted with vapours of sulphur, selenium or tellurium which have been diluted with an inert gas. The process is particularly described with reference to the production of zinc sulphide.  Oxidizing gases present in small quantities in the inert gas are removed by the sulphur prior to coming in contact with the zinc.  In Fig. 1, nitrogen is passed through pipe 7 into a narrow chamber 5 surrounded by a heating jacket 6.  Sulphur vapour enters by conduit 8, and mixed with the nitrogen reacts with zinc vapour entering by conduit 9.  In Fig. 2, the end portion of the narrow chamber is constructed as a sulphur-vaporizing retort 12, nitrogen and zinc vapours entering by conduits 15 and 14 respectively.  The chambers 5 and 13 may be provided with baffles, and have a temperature of 600--935 DEG  C.  A slight excess of sulphur should be used.  The inert gas carrying this excess and zinc sulphide in suspension is drawn by a fan to a bag room or electrostatic dust precipitator, if desired, through a cyclone separator to remove coarse particles.  The collecting chamber may be maintained at 500 DEG  C., to avoid condensation of sulphur, but if necessary, the product is heated to expel any sulphur which may have condensed with the zinc sulphide.  In either case, the hot zinc sulphide is cooled in a current of inert gas.  The particle size of the zinc sulphide varies indirectly with the amount of nitrogen use to dilute the sulphur vapour. Specifications 1047/79, 1131/79, [both in Class 1], and 404,886 are referred to.

Abstract: 1,043,569. Semi-conductor and substrate. FERRANTI Ltd. Aug. 31, 1965 [Sept. 3, 1964], No. 36200/64. Heading H1K. Discrete portions of semi-conductor material on a supporting substrate are produced by oxidizing both faces of a monocrystalline parallel faced slice of semi-conductor material, coating one oxidized surface with a temporary supporting layer, removing the oxide from discrete areas of the other face of the slice, etching completely through the exposed parts of the slice, coating the exposed surfaces with an insulating layer forming over the remaining portions of the slice the said supporting substrate and removing the temporary supporting layer. Both the temporary and supporting substrate must have a thermal coefficient of expansion equal to that of the slice. One stage of the process is shown in Fig. 5 the silicon slice has been etched into discrete portions 4 each of which is surrounded by a silicon oxide layer 2 and 5. The temporary support 3 is of polycrystalline Si grown by vapour phase deposition whilst the supporting substrate 4 is grown in a similar way. Alternatively the substrates 3 and 4 may be of silicon oxide or carbide. The insulating coating 5 may be of silicon dioxide, monoxide or nitride. A conductive layer may be formed between the discrete portions 4 prior to the coating 5 being applied. The slice of silicon may have a n layer on top of an n+ layer to give high speed switching transistors.

Abstract: 1275690 Smoothing leather REALISATIONS INDUSTRIELLES ET ASSISTANCE TECHNIQUE and Y GRENIER 4 Aug 1970 [5 Sept 1969] 37530/70 Heading C6C A machine for smoothing leathers comprises a glass smoothing cylinder 8 carried by the free end of an oscillating arm 3 supported on levers 4, 5 such that the cylinder traverses a table 2, and resilient table-supporting means consisting of an inflatable tubular bladder 44 which is fitted within a space between the underside of the table 2 and a U-section or other suitable support 25 fixed with respect to the machine frame 1. Preferably, the support 25 is welded to a plate 26 which carries, by brackets 96, 97, a framing shelf 93 surrounding the table 2, the brackets 96, 97 being adjustably connected by bolts 98 and slots 99 to enable the height of the framing shelf to be varied. Plate 26 is welded to a profiled member 27 or twin welded to the frame 1. Table 2 is guided for movement perpendicular to its plane both by side pieces 22A, 23A, which are secured to the underside of the table and co-operate with the outer side walls of the support 25, and also by pins 28, welded to the underside of the support 25 adjacent each of its ends and engaging apertures in plates 37 which are secured to pairs of side members 22, 23 the latter being welded to the underside of the table. The lower end of each of the pins 28 carries a plate 31 the ends of which carry anchor pins for a pair of springs 48 which urge the table to a lowered position. When the bladder 44 is inflated to a suitable pressure the table rises until the desired working position is reached. This position is set by adjusting screws 35 which are threaded in bosses 36, on the plates 37 and co-operate with the underside of plate 31. The air supply to the bladder comprises a pressure-reducer 62, a safety valve 63, a pressure-regulator 65, and a pedal-operated three-way valve 58, whereby the table can be lowered to remove treated leather and insert a fresh piece, and then raised again for operation of the machine. The arm 3 is oscillated by a disc crank 13 via a link 15. The cylinder 8 is secured in jaws 72, 73 which can be orientated about an axis parallel with the direction of movement of the cylinder over the table, by means of a pivot bolt (77), Fig. 6 (not shown), and screw adjustment means (84, 85).

Title: Improvements in and relating to means for recording data magnetically on record media

Abstract: 1,144,254. Magnetic recording of coded data. LONDON TRANSPORT BOARD and R. DELL. 18 May, 1967 [22 Aug., 1966], No. 37586/66. Heading G5R. Apparatus for magnetic recording of coded data on a travelling record medium comprises a rotatable wheel, of magnetic material, having a plurality of teeth located around at least part of its periphery, and being arranged to rotate in timed relationship with the record medium, and recording heads arranged to produce output pulses, corresponding to the teeth, for recording, on the medium, data marks having a predetermined code arrangement. In one embodiment the apparatus is installed in a (railway) ticket-issuing machine for tickets of one value. The wheel is a phonic wheel in the form of a steel-toothed disc mounted on the driving mechanism of the machine; it has, e.g., thirty-one teeth extending over only a part of the periphery of the wheel corresponding in length to the length of the ticket. At least one recording head is located adjacent the periphery of the wheel so that a pulse may be generated therein each time a tooth passes the head; the spacing of the teeth determines the spacing of the magnetic marks (e.g. parallel, transverse) along at least one longitudinal edge of the ticket. Preferably the marks are grouped to designate data such as station of origin, value, date, single, return, child's fare or cheap fare. Whether or not a given pulse generated by the wheel will give rise to a coded mark on the ticket depends on the code arrangement determined by the diode matrix. The pulses from the phonic wheel pass through an amplifier whose output is connected to the first stage of a counter preferably comprising five bi-stable state devices the counter, thus identifying each tooth. The (amplified) output signals from the counter are decoded in a diode matrix from which 31 outputs are provided; these are coupled to the inputs of a diode encoding matrix having diodes in predetermined positions corresponding to the code required. A manually-operable date switch is also connected to the encoding matrix. Output signals from the encoding matrix are applied via gating devices and amplifiers to top track and bottom track recording heads for recording marks along both longitudinal edges of the ticket. In a second embodiment (also for tickets) the machine has separate ticket rolls, one for each value, and is operable, by separate push buttons in a booking office, or in response to the insertion of different coins by a passenger.
