Title: Paraffin wax compositions
IPC: C08L91/08
Filed: 1956-10-08
Abstract: A wax composition comprises a major proportion of a crystalline paraffin wax and a minor proportion of an aromatic extract having a viscosity of at least 350 S.S.U. at 210 DEG  F.  The aromatic extracts consist predominantly of aromatic and naphthenic hydrocarbons and may be obtained by extracting petroleum oils, particularly residual oils, or oils obtained by hydrogenating coal, with solvents or by adsorption on solids such as clay. Solvents referred to are liquid sulphur dioxide, phenol, cresylic acid, furfural, nitrobenzene, chlorex, sulphanes and sulpholenes; mixtures of solvents such as phenol with cresylic acid, a liquid sulphur dioide with benzene or toluene, or cresylc acid with propane are also mentioned.  The extracts may be re-extracted with solvent, e.g. Edeleanu extracts of lubricating residual oils may be re-extracted with gasoline.  The petroleum oils used in the extraction may first be deasphalted and dewaxed; 0.2-5 per cent of the aromatic extract may be used.  The crystalline paraffin waxes consist of straight chain paraffins with minor proportion of isoparaffins, olefins and cyclic hydrocarbons, and may have melting-points of 100-190 DEG  F. and a molecular weight of more than 400.  These waxes may be obtained by dewaxing lubricating oils, especially distillate oils, for example by solvent dewaxing with methyl ethyl ketone, methyl isobutyl ketone or acetone or mixtures thereof with benzene, coding, and filtering or centrifuging to remove wax.  Alternatively, high melting-point waxes may be obtained by dewaxing residual oils.  The wax may be refined by percolation through clay.  The refined waxes may contain less than 1 per cent oil.  Specifications 380,954, 417,617, 525,403 and 625,505 are referred to.

Abstract: 1,119,793. Electrostatic screen-printing. CONTINENTAL CAN CO. Inc. 21 July, 1965 [27 July, 1964], No. 30920/65. Heading B6C. An article 10 of electrically non-conductive material e.g. acetate plastic, is printed by first providing the article with a distributed electrostatic charge, then locating the charged article in spaced relationship to an electrically conductive screen stencil 20 to establish an electric field between the article and the screen, and finally forcing electrically charged toner particles 34 through the stencil, so that under the action of the electric field the particles are deposited on the article in the required pattern and are subsequently bonded to the article by heating, or by exposure to the vapour of a toner solvent. The screen 20 may be earthed to increase the strength of the field. The charge on the article 10 is formed by placing the article between two corona electrodes connected to avan der Graff generator so that negative ions 15 are deposited on one face and positive ions 16 are deposited on the other face. The charging of the screen 20 under the action of the electric field may serve to charge the non-conductive toner particles, but the particles may be mixed with much. larger conductive particles of iron filings or other magnetic material whereby the particles are charged triboelectrically. The mesh of the screen is such that only the toner particles can pass therethrough. A brush may be used for forcing the particles through the screen, but in the case where the mixture including iron filings is employed, a bar magnet 31 may be dipped into some of the mixture to pick up a quantity 32 thereof and supply it to the screen. The article may be a flat sheet or a thin walled plastic bottle, and an electrode 47, Fig. 5 (not shown) connected to the screen 45 may be disposed within the bottle to increase the electric field.

Abstract: 1481024 Electronic timepieces SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES S A 9 June 1975 [15 July 1974] 31255/74 Heading G3T In an electronic timepiece comprising a stepping motor M, Fig. 3, driven by pulses from a battery source VDD under the control of an oscillator and frequency divider in a CMOS integrated circuit IC, a field effect transistor switch SR is controlled to have a relatively high resistance during each drive pulse so that, in effect, it disconnects the said circuit from the battery and the circuit is substantially entirely energized by the charge in a capacitor C D . This ensures continuous functioning of the oscillator and divider circuits even though the battery terminal voltage falls during each motor drive pulse. In the intervals between drive pulses the transistor switch SR is controlled to have a relatively low resistance and will permit energization of the circuit IC by the battery and the complete recharging of capacitor C D . The transistor SR is arranged to have two discrete values of resistance in accordance with a logical switching signal at its control gate, this signal having the same form and being in coincidence with motor control pulses supplied by circuit IC. to the motor drive pulse circuit. Fig. 4 (not shown), illustrates in more detail the arrangement shown in Fig. 3.

Title: Improvements in or relating to a method of plasma arc cutting
Inventor: HAASE LOTHAR
IPC: B23K10/00
Filed: 1966-07-13
Abstract: 1,131,977. Cutting by fusion. KJELLBERG & ELEKTRODEN & MASCHINEN G.m.b.H., in VERWALTUNG. 13 July, 1966, No. 31519/66. Heading B3V. [Also in Division H2] In plasma arc cutting using high power and pilot arc starting, the main arc is started at a lower output for "cutting-in" than for "initial cutting". "Cutting-in" is an operation in which the torch is positioned over a workpiece prior to the striking of the arc for piercing or blind cutting. "Initial cutting" occurs when a torch is moved laterally towards the edge of a workpiece to start cutting. In "initial cutting", the pilot arc is struck before the torch reaches the work. A common source 9, Fig. 3, supplies the main and the pilot arcs, a resistor 14 being connected in the pilot arc circuit. Argon is fed through the nozzle 3 and when the pilot arc strikes between the nozzle 3 and the electrode 1, a relay 6 having a delayed operation shunts a resistor 8 in the main arc circuit. The main arc strikes to the work before the torch is over the work so that initial current is, due to the length of the arc, not excessive. When the main arc strikes hydrogen in addition to argon is fed through the nozzle 3. It is stated that the pilot arc extinguishes, when the main arc strikes, to release relay 6 to insert the resistor 8 into the main arc circuit whereupon the desired cutting current is set by an adjustable resistor 11. In "cutting-in", the main arc strikes before relay 6 has time to shunt the resistor 8 and the latter limits the main arc current to prevent burning of the nozzle 3. In a modification, the pilot arc is supplied by a separate source 5, Fig. 1. The relay 6 when operated shunts a resistor 8 in the control circuit of a transductor 12 controlling the main arc current. In a further modification, relay 6 is replaced by a voltage responsive relay.

During the first state, no modulation is applied via S2, and the control signal d is applied via TR1 to storage capacitor C2 and via TR11 to storage capacitor C12. In this state the upper plate of capacitor C2 and control input el are at the full potential d, whilst the lower plate of capacitor C2 is at a lower potential, determined by potential divider R14, B15. In the intermediate state S1 is operated to its other state, to turn off transistor TR1, and frequency control of oscillator O is effected only by the control signal derived via F. When the transient condition associated with the switching of TR1. has ended S11 is operated to its other state to turn off TR11, disconnecting the control signal from capacitor C12 and S2 is operated to connect the modulation signal M to input e2.
