Title: Improvements in apparatus for charging containers with liquids
IPC: F17C5/02
Filed: 1957-04-02
Abstract: 802,224. Filling containers with liquids. EYLES, I. F. April 2, 1957, No. 10703/57. Class 125(2). Apparatus for charging containers, e.g., aerosol containers, with liquids under pressure, e.g., propellant liquid, comprises an adjustable container support 2 and a filling ram B having a valved outlet engaging the container and driven by an operating ram C descent of which is initiated by the placing of a container on support 2 and ascent of which is initiated by a reversing valve 21 operated by ram C. When a container is placed on support 2, it actuates rod 10 to open valve 11 to allow fluid under pressure to flow through pipe 13 to the top end of ram C whereupon its piston descends. The piston rod 17 extends into ram B and carries the piston thereof. During descent of rod 17, ram B first descends until its outlet seals on the container mouth, then the outlet valve and the container valve are opened, the latter by the liquid pressure, and then the piston of ram B injects the liquid charge. Lastly, abutment 24 on rod 17 actuates reversing valve 21 whereupon pressure fluid from pipe 20 enters ram C to raise its piston and rod 17. This first allows the outlet and container valves to close and lifts ram B till stop member 47 stops it and then rod 17 lifts the piston of ram B to suck in a fresh charge of liquid from source E. Lastly ascent is stopped by abutment 24 meeting stop 26. Meanwhile spring 12 has closed valve 11 and ejected the filled container. Interchangeable outlets for ram B are provided and the ram includes a check valve to prevent loss of liquid when changing the outlet.

A rolling mill stand includes work rolls 8 which can be rotated in a framework 2, about a fixed passline 6, to assume either vertical or horizontal positions, a stationary motor 52 driving the rolls in either position. To move the rolls from a horizontal position, Fig. 1, to a vertical position, Fig. 6, a driving shaft 11 is uncoupled at 30a from a gear-box 34, and the rolls, together with driving pinions 10 and the shaft 11, are pivoted on a cradle 84, Fig. 8, to a vertical position. The shaft is then coupled at 70 to a shaft 66 which is itself driven from the gear-box 34. The cradle is provided with rollers 92 which engage in arcuate tracks in the side walls of the framework 2, and is rotated by motor driven chain wheels 150 associated with chains 152 and counter-weights 158. A longitudinal sled 97 is accommodated in the cradle 84, and directly supports the rolls 8, in their housings 7, and the spindles 10. Adjustment of the sled relative to the cradle, by a motor-driven screw, moves the rolls transversely of the passline 6, a pair of clamps normally fixing the shed relative to the cradle. The housings, which are provided with wheels 101, are normally bolted to the sled, but may be rolled from the sled (when in a horizontal position) to facilitate roll changing. The cradle is positively located in either of its working positions by retractable locking pins. The spindles 10a, 10b and 10c, Fig. 10, are hollow, the upper ones accommodating shafts 9 with spherical gear members 16 and 17 at their ends, while the lower one accommodates a splined member 24. The splined connection allows retraction of the shaft 11 for roll pivoting operations, and permits the rolls to be adjusted axially. A number of such stands can be arranged in tandem.

Filed: 1946-04-09
Abstract: 610,910. Television. LAWSON, D. I., and PYE, Ltd. April 9, 1946, No. 10851. [Class 40 (iii)] In a cathode-ray device in which the electron beam is deflected by a deflecting coil, the amplitude of the deflection is varied by varying the number of effective turns on the deflecting coil by a switching means which simultaneously varies the value of an inductance connected in series with the deflecting coil such that the total inductance of the circuit remains substantially constant for different positions of th e switch. As shown in the drawing, the. line deflecting coil 1 which is fed from the line transformer 2 connected in the output circuit of the line amplifier or oscillator valve 3 is provided with a series of tappings a, b, c and is connected in series with an inductance 4 which is also provided with a series of tappings a<1>, b<1>, c<1>. A switch 5 is provided for interconnecting tapping points of the line deflecting coil and of the inductance 4, the arrangement being such that as the number of turns on the deflecting coil which are effective to produce deflection of the cathode-ray beam is reduced, by changing the position of the switch, the number of turns of the inductance 4 which are connected in series with the deflecting coil is simultaneously increased, and vice versa, thus maintaining the total inductance of the circuit substantially constant at different positions of the switch. It is stated that the invention is particularly applicable in arrangements in which the high voltage supply for the cathode-ray tube is derived from the line oscillator of the apparatus, for example, through the rectifier 6.

Abstract: 975, 267. Counters; shift registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 27, 1961 [April 15, 1960], No. 11019/61. Headings G4A and G4C. [Also in Division H3] A multistable-state circuit, which may be adapted to serve as a shift register, pulse counter or rug counter, comprises a plurality of bi-stable circuits, each comprising a tunnel diode biased to have two stable states of operation and connected to the base electrode of a transistor T, the output taken from the collector electrode of each transistor except the last being coupled through a capacitor C to the input of the succeeding bi-stable circuit. The tunnel diodes are energized from a source V s  of positive voltage periodically interrupted for short intervals. This voltage and resistors R 1 , R 2  are so chosen that on the application of this voltage each diode E normally assumes its lowvoltage stable state P, Fig. 2; however the simultaneous application of a positive current input pulse i in  of sufficient amplitude ensures that the corresponding diode assumes its high-voltage state Q, thus biasing transistor T into conduction. When the next interruption in the source V s  occurs current ceases to flow through the first diode E and the corresponding positive excursion occurring at the collector of the corresponding transistor T sends a pulse of current through capacitor C to send the second diode to its high-voltage state. The time constants of the circuit are so chosen that the state of the second diode is maintained until the voltage V s  is restored; the second diode is then held in the high-voltage condition until the next interruption in the voltage V s  occurs whereupon the high-voltage condition is transferred to the third diode. The collector of the final transistor may be returned through a capacitor to the input i in ; upon setting one diode to the highvoltage state, this state will step continuously round the circuit at a rate depending upon the rate of which interruptions occur in voltage Vs. The circuit may also be used to count pulses from the source Vs; the first diode is initially set to the high-voltage state and then by sensing the transistor which is conductive the number of pulses applied from V s  can be determined.

Title: The manufacture of dyestuffs of the gallocyanine series
IPC: C09B19/00
Filed: 1933-04-13
Abstract: Gallocyanine dyes are prepared by condensing according to known methods gallic acid or derivatives thereof with a nitroso compound of a secondary or tertiary aromatic amine of the general formula <FORM:0417875/IV/1> wherein "aryl" indicates a residue of the benzene series and R is hydrogen, alkyl, substituted alkyl, aralkyl, or substituted aralkyl.  These dyes can be transformed into other derivatives which still contain the grouping <FORM:0417875/IV/2> according to the usual methods known in this series of dyestuffs; thus the carboxylic acid group can be split off, the dyes may be reduced to the leuco form, or condensed with aromatic mono- or diamines or sulphonic acid derivatives thereof, or with aldehydes, phenols, naphthols or naphtholsulphonic acids, or they may be sulphonated.  The products are clear, fast dyes having a good solubility in water.  In examples, (1) gallic acid is condensed with nitrosomethylphenyltaurine in methanol (or ethanol or glacial acetic acid); when printed as chrome-lake good blue shades are obtained, and chromed wool is similarly dyed blue; by heating the dye in weak alkaline solution the carboxy group is split off; using nitroso-di-(sulphoethyl)-aniline for the condensation a similar dye is obtained; (2) pyrogallic acid is condensed with nitrosomethylphenyltaurine to give a blue dye; (3) gallamide is condensed with nitrosoethylphenyltaurine to give a greenish-blue dye; this may be transformed to its leuco compound by means of zinc dust and hydrochloric acid and this can be printed as chrome lake in solution or after isolation; or the anilido compound is obtained by heating with aniline, and this can be used for printing purposes directly or after sulphonation; or the dye may be condensed in hydrochloric acid solution with formaldehyde, or with resorcinol to give a phenocyanine from which the carboxylic radicle may be split off by boiling with aqueous soda; (4) gallamide is condensed with nitroso-o-tolyltaurine and with nitrosophenylbenzyltaurine to give blue dyes; using nitrosmethylphenyltaurine for the condensation and further condensing the product with p-aminodiethylaniline an arylidogallocyanine derivative is obtained.  The nitroso compounds employed as intermediates are prepared by introducing the nitroso group into tertiary alkylaryltaurines by means of sodium nitrite and hydrochloric acid or by similar treatment of secondary aryltaurines to give nitroamines which are converted into the p-nitroso compounds by introducing into concentrated hydrochloric acid.
