Title: Improvements relating to record cards or sheets for office machinery
IPC: G06K1/12
Filed: 1956-05-10
Abstract: 817,902. Record cards. DIRKS, G. July 24, 1957 [May 10, 1956], No. 14498/50. Class 106 (1). A record card or sheet 1, Fig. 1, has tracks 2, 3, 4, in one of which, 3, a series of characters is recorded in a visually readable form, in another of which, 4, is recorded a mark 6 to be sensed by the machine in a position corresponding to the character represented and in the third of which, 2, is recorded a series of digit marks 5. The value of a mark 6 is determined by its position in the zone 7, the record being sensed in the direction of the arrow 46, a gate being opened by the mark 6 so that digit marks to the left of it can pass to a counter. The gate is reset by a mark counter when it reaches ten. Such a record strip may be attached adhesively to another document. In another form to reduce the length of the track required for each zone, two character tracks are provided one for the even numbers and one for the odd. The record marks are placed in one or other of the two tracks adjacent the two character tracks. In the form of Fig. 3 numbers are represented by marks 23 in track 21 as before but alphabetic and other characters are represented by such a mark 23 and in addition a mark 24 in track 22, this indicating which track of character tracks 26-29 contains the character represented. Thus in zone 32, mark 24 indicates that the character is in the first track 29 and mark 23 indicates that it is in the third position, i.e. " C." The marks may be recorded twice, one recording serving as a check on the other. One of the recordings may be in complement form so that if both are added during sensing a check is given when zero is produced. The marks may be recorded in magnetic ink by a specially formed printing wheel which is magnetized to polarize the marks during the printing; otherwise the marks may be magnetized subsequently. Other methods of recording may be used, e.g. ordinary marks to be sensed photo-electrically or radioactive marks sensed by a suitable detector. Data may be recorded in two independent methods in the same area of the record.

Abstract: 475,275. Impedance networks ; piezoelectric crystals. STANDARD TELEPHONES & CABLES, Ltd. May 22, 1936, Nos. 14547 and 14548. Convention dates, July 2, 1935 and July 27, 1935. [Classes 40 (iii) and 40 (v)] A lattice section comprises a pair of fourelectrode crystals or a pair of two-winding magnetrostrictive oscillators, each element providing two arms of the lattice. In the arrangement shown in Fig. 1, a lattice section comprises two crystals 10, 11, each of which carries two pairs of plates, those of crystal 10 being connected so as to form the line arms while those of crystal 11 form the lattice arms of the section. The connections may be such that the crystals vibrate in the flexural mode. The line and lattice arms may have a resonance frequency in common, Fig. 9 (not shown) ; otherwise a line anti-resonance coincides with a lattice resonance and vice versa, Figs. 8, 9 (not shown). Inductances Lo are added in order to broaden the pass band. Instead of the crystals 10, 11 and inductances Lo, two-coil magnetostrictive resonators in series with condensers may be used, Fig. 7 (not shown). The crystals may be adapted to vibrate in a plane mode, Fig. 2, or a flexural mode, Figs. 10, 12. According to the Specification as open to inspection under Sect. 91 a lattice section may comprise four four-electrode crystals vibrating in the flexural mode, the electrodes of each crystal being cross-connected, but this subject-matter does not appear in the Specification as accepted. Piezo-electric crystals. A crystal, Fig. 2, for use in a wave filter has two pairs 12, 121 and 13, 13<1> of opposite electrodes. The electrodes are formed by silver-plating the faces of the crystal and removing the plating along the centre lines and edges of the faces. The Specification gives instructions for dimensioning flexurally - vibrating X-cut crystals with their widths variously inclined to the Z axis and mechanical axis of the mother crystal. Crystals may be adapted to vibrate in flexural modes at relatively low frequencies. Thus the crystal 61, Fig. 10, having two opposite pairs 62, 64 and 63, 65 of electrodes, and four pairs of knife-edged clamps 74, vibrates flexurally about two nodal lines 66, 67. A crystal shaped like a tuning-fork, Fig. 12, has two pairs 35, 37 and 36, 38 of electrodes, and two pairs of clamps 41, 42 and vibrates flexurally about a nodal line 39. Magnetostrictive vibrators. A magnetostrictive vibrator with two operative windings 18, 19, Fig. 4, which may be side by side or wound one over the other, has a tubular core 16 slotted longitudinally to prevent eddy currents, and a polarizing-magnet 21 with polarizing-winding 22.

Abstract: 1330914 Sealed system compound formation ARTHUR D LITTLE Inc 12 May 1971 [15 June 1970] 14562/71 Heading C1A Compounds of at least two elements, at least one of which is a metal and both or all of which exist in solid or liquid form at ambient temperatures while at least one of said elements exerts an appreciable vapour pressure at the reaction temperature, are prepared by sealing the reactant elements within a reaction system by means of a liquid encapsulant at a temperature below the reaction temperature and heating the encapsulated system to the reaction temperature to produce said compound, whilst continuously applying to the system a gas under a pressure at least equal to the partial pressure of the most volatile component present in the system, both the encapsulant and the gas used being inert with respect to the reactant elements and product. The introduction of a doping agent for the compound produced into the reaction system is also envisaged. The encapsulant used is preferably a solid at room temperature (e.g. boric oxide or barium oxide, alone or in admixture with barium chloride or sodium fluoride) and is conveniently initially placed on top of said elements, melted and then allowed to flow downwardly through the mass of elements, the permeation of said mass optionally being assisted by the inert gas pressure. The encapsulant may be separated from the reaction components by a foraminous barrier. Groups III-V and Groups II-VI compounds may be prepared by the present process and the examples describe the preparation of GaAs and GaP. Specified examples of ternary products are HgCdTe, GaAsP and GaInAs.

Title: Improvements in the conditioning of yarns or threads
IPC: D06B3/06
Filed: 1946-05-21
Abstract: A filament, yarn or thread is passed through a foam of conditioning liquid, e.g. a textile lubricant in apparatus which comprises a closed container, means for maintaining a foam of a conditioning liquid therein and means, including filament inlet and outlet orifices, for guiding the running filament through the foam.  Gas may be admitted through an orifice placed in the lower part of the container so as to be <PICT:0625032/IV (c)/1> <PICT:0625032/IV (c)/2> below the liquid level or placed so as to whip the liquid into a foam by directing a jet of the gas on to the surface of the liquid.  If desired, the receptacle in which the foam is produced may be separate from the treatment vessel but connected to it by a conduit for the foam.  As shown in Fig. 1, cylinder 1 is provided with end caps 2, 3. An air-tube 4 extends axially into the cylinder, and at least one orifice 8 is provided at the lower end.  Air is blown into the liquid in the cylinder to produce a foam which fills the cylinder.  The filament is traversed across the cylinder between eyes 9, the length of filament under treatment being regulated by guide 10.  In a modified construction, the lower end of the cylinder is open and stands in a tray containing the conditioning liquid.  As shown in Fig. 3, a horizontal cylinder 16 is provided with inlets 28 and outlets 27 for several filaments.  Air from perforated pipe 23 bubbles through conditioning liquid in the cylinder and produces a foam which fills the cylinder.  The cylinder may be transparent.  The process may be applied to the conditioning of nylon yarn immediately before knitting and may be effected on the knitting machine itself between the bobbins and the knitting needles.  The Provisional Specification describes an apparatus in which the filament enters and leaves the treatment vessel at the top and passes through a guide immersed in the foam.  The conditioning liquid may be a solution of a soap.
