Abstract: 1,174,977. Knitting; yarns. VYZKUMNY USTAV PIETARSKY. 3 March, 1967 [3 March, 1966], No. 10092/67. Headings D1K and D1W. Cords are formed from yarns knitted on small groups of needles of a warp knitting- machine to which the yarns from the guides of two guide bars are fed such that the outer wales are composed of loops formed in each course from a single yarn only whilst the centre wales are composed of loops formed in each course from two yarns as illustrated in Fig. 3. The completed knitted cords are wound up on a beam 31 and the nature of the structure causes the outer edges of the knitted fabric to curl inwardly to form a somewhat tubular cord. The structure may be in a tricot stitch or other warp knitted structure provided the outer wale or wales or each side is or are of single yarn loops whilst the centre portion is composed of loops formed in each course from two yarns.

Title: Improvements in or relating to the production of films of hygroscopic, non-fibrous, organic material
Inventor: BERRY WILLIAM
IPC: B29D7/00
Filed: 1950-04-26
Abstract: Two or more coated films of hygroscopic, non-fibrous, organic material, of the type which normally develops when immersed in water an electric charge of negative sign, are produced in a machine, which differs from the normal type used for the production of a single film in that it is provided with two or more extrusion slits but, like the machine of the normal type, has only one set of drying rolls in the drying oven, by applying to the films after their formation, at least on those surfaces which are subsequently to be brought into contact, a liquid aqueous dispersion of wax, the wax particles of which carry, as a result of previous treatment to reverse the sign of the electric charge normally developed by the films or developed by the wax particles of the liquid aqueous wax dispersion (when made with the aid of an anionic surface-active agent), an electric charge of opposite sign to that developed by the films in contact with water. The treated films are then assembled and superimposed and passed through the drier while in surface contact with one another as if they were a single composite or multilayered film, whereafter the dried films are separated.  The term "wax" is defined as in Specification 695,555 and the wax dispersions, which may contain colloidal silica and (or) alumina, may be prepared as described in that Specification, which relates to the coating of single films in the same manner as in the present Specification.  In an example, two films of gel regenerated cellulose are cast simultaneously and passed simultaneously, while separated from each other, through a liquid aqueous bath containing glycerol, dispersed paraffin wax (blended with carnauba wax), colloidal silica and cetyl trimethyl ammonium bromide.  Excess liquid is removed from the surfaces of the films by passage through squeeze rolls and the treated films are then assembled and superimposed and dried by passage in intimate contact with one another over drying rolls heated to 85-90 DEG  C.  The dried films separate easily from each other at the exit from the drying oven.  Examples are given also of the simultaneous production of coated regenerated cellulose films in a similar manner using the other wax dispersions described in Specification 695,555. Specifications 386,775, 423,365, 657,342 and 673,255, and U.S.A. Specification 2,206,046 also are referred to.

Title: Improvements in or relating to typographical composing and slug-casting machines
IPC: B41B11/38
Filed: 1929-04-08
Abstract: 323,695. Hart, H., (Mergenthaler Linotype Co.). April 8, 1929. Justifying matrices.-Relates to justifying-apparatus of the kind in which the Justification is carried out in two stages by a vertically movable bar, which engages the space bands at their lower ends, the bar operating in an inclined position in the first stage, and in a horizontal position in the second stage. In order to secure a tight lock-up of the line with uniform spacing, and in order to avoid damage to the spacebands resulting from their being engaged successively by the justification bar during the second stage, the bar is caused to assume an horizontal position at the end of the first stage. The justification-bar P<3>, Fig. 2, is, as heretofore, operated by rods p<1>, p<2>, bearing collars P, P<4>, which are engaged by separate levers M, M', actuated by springs M<2>, M<3>, Fig. 4, under the control of cams 0', O<2>. The left-hand end of the bar p<3> normally rests upon the upper end of a. link p<5>, so that the bar occupies an inclined position. The lever M also controls a wedge L, Fig. 2, having upper and lower high parts and an intermediate low part, which effects a temporary release of the movable vice-jaw F, to permit the matrices to be aligned against the mould. The cams O<1>, O<2> are formed with relatively low portions O<3>, O<4>, and an intervening high portion O<5>, to effect, the successive movements of the bar P<3> and the wedge L. According to the invention, the moving of the bar p<3> to horizontal position is effected by forming the lower portion O<3> of the cam 0', which controls the rod P', with a recess or dip O<7>, and by positioning the collar P on the rod p<1> slightly lower than usual. If desired, the right-hand end of the justification-bar may be lowered slightly. by means of a slight rise in the low section O<3> of the cam O<2>, before the opposite end is swung upwardly, in order to facilitate the adjustment of the line towards the right.

[Class 40 (v).] In a Bellini-Tosi system designed to operate over a plurality of wave-length ranges, loading reactances are used in conjunction with the frame circuits in such a way that when the system is being used on any one range, the resonance frequency of the aerial system is within another range. As shown, in an arrangement having two wavelength ranges, the fixed loops AF, PS feed fixed goniometer coils A1, F1 and P1, S1 respectively and the search coil SC is in circuit with a tuning condenser SCC and coils CCA1 and AC, the former of which is coupled to a coil CCA connected to an open aerial OA and earth through a reversing switch RS, the latter being coupled to a coil AC1 leading to the amplifier. Fixed and variable loading capacities FC and VC are adapted to be switched across the goniometer coils for one wavelength range by an earthed rod SL which also operates the switch RS and the rangechanging switch of the amplifier. The reversal of the cardioid diagram which would take place on changing from one range to the other is avoided by the operation of switch RS. Other phasereversing means may alternatively be employed or the search coil circuit or an intermediate circuit may be rendered aperiodic on one of the ranges by short-circuiting the condenser SCC.

Title: Improvements in or relating to method and apparatus for flash testing
Inventor: GREANIAS EVON C
IPC: G01N25/52
Filed: 1956-04-16
Abstract: The flash-point of a hydrocarbon liquid is determined by heating a stream of the liquid flowing through a tube 11, maintaining a pool of the heated liquid in a cup 16 of a flash chamber 14, admitting air through an annular channel 14a and/or through a jet 26, applying intermittently a spark between electrodes 22 and 23, and automatically measuring the temperature of the liquid with a thermocouple 20 upon the occurrence of a flash.  A constant liquid level is maintained by a weir 17, the liquid flowing into an annular trough 18 and then through an outlet 19.  A pulse circuit 24 controls a spark coil 25 which applies a periodic potential to the centre electrode 23.  When a flash occurs the ions formed by combustion conduct electricity between the electrodes 22 and 23 under the influence of a D.C. voltage supplied by source 31.  The polarity of this current is such as to give a positive signal at a flash detecting circuit 27. The spark coil 25 is connected to a voltage supply 30 to give negative voltage pulses, so that current due <PICT:0824943/III/1> to sparks does not operate the flash detecting circuit 27.  The flash detecting circuit 27 operates a relay 28 which switches off a heating coil 12 in tube 11 for a controlled period of time at least greater than the period between sparks.  When the liquid temperature in the cup 16 is lowered below the flash point, the heating is automatically resumed until another flash occurs.  The temperature is indicated and recorded by a potentiometer 21.
