Title: Gas cock
IPC: G05D23/00
Filed: 1964-05-04
Abstract: 1,004,555. Valves. JUNKERS & CO. G.m.b.H. May 4, 1964 [May 4, 1963], No. 18359/64. Heading F2V. A gas cock for controlling the supply of gas to a main and a pilot burner having a thermoelectric ignition safety device, comprises an electromagnet 27 which is fitted within the cock plug 20 and is stationary with respect thereto, an armature plate 29 capable of being pressed against the electromagnet 27 and co-operating with a gas shut-off closure member 14 provided in the path of the gas through the cock 20, the coil of the electromagnet 27 being connectable to the current conductor 31 of the thermoelement by means of a sliding contact 33, 312 which is open only in the zero position of the cock. The contact member 33 is mounted on an insulator 34 fixed to the cock 20 and comprises a U-shaped section element which extends through an angle of 120 degrees. The contact head 312 is mounted in an insulator 35 in the valve casing 10. In operation, for connecting the inlet 11 to the main burner outlet 12, the handle 26 together with spindle 30 is pressed inwardly to move the armature 29 against the electromagnet 28 to open valve member 14 and allow gas to flow to the pilot burner outlet 37. The handle 26 together with the cock 20 is then rotated to bring the contacts 33, 312 into connection. Ignition of the pilot burner developes a current which is fed through the contacts 33, 312 to energize the electromagnet 28 to retain the armature 29 in position, which also holds valve 14 open. The cock 20 is then rotated to align a side wall port 20 (not shown) with the main outlet 12. Further rotation of the cock 20 effects control of the gas amount passing through the outlet 12. If the electromagnet becomes de-energized, the valve 14 is moved to the closed position by a spring 15 and the cock 20 has to be returned to the zero position before ignition can be repeated. The sliding contacts 33, 312 may be reversed.

Patent GB-497977-A (GB)
Title: Improvements in or relating to the production of alkali cellulose from cellulose sheets
IPC: C08B1/12
Filed: 1937-07-02
Abstract: Apparatus for the continuous production of alkali cellulose from cellulose sheets comprises a train of containers for the sheets carried by an endless conveyer to which intermittent motion is imparted, a lye tank through which the containers pass, and a press located in the path of the containers and operated in synchronism with the intermittent rest periods of the containers. The containers for the cellulose sheets may be collapsable, and freely supported between endless chain conveyers.  During their travel through the lye tank the spacing between the containers is reduced by supporting the containers on a second slower-moving conveyer, which allows the main chain conveyer to hang in loops between the conveyers.  Preferably, the press and the means for advancing the conveyer chains are operated hydraulically.  In the device shown, the cellulose sheets are loaded into the containers 1 from a platform 16.  The containers are supported by endless chains 2 which are given intermittent motion by the hydraulically-operated pistons 26 and 27.  On entering the lye tank 15, the containers become supported by a second and slower-moving chain conveyer 35, which moves them slowly through the lye in close relationship.  The containers then pass between the plates of a hydraulic press 18, the expressed lye being collected by means of a hopper 40, and after discharging their contents on to a conveyer 21, return to the charging position 16. The containers are preferably constructed with a number of perforated metal spacing plates connected by means of collapsable links or triangular pieces by means of <PICT:0497977/IV/1> which the plates may be automatically correctly spaced after removal of the pressed cellulose sheets and before introduction of the fresh sheets.  The discharge from the hopper 40 is provided with a three-way cock for separating the so-called yellow lye from the black lye.  The position of the cock is controlled by the ram of the hydraulic press.

Abstract: 1434474 Controlling speed of electric drills METABOWERKE KG OLOSS RAUCH & SCHNIZLER 30 April 1974 [12 May 1973] 18865/74 Heading H2J  A universal motor 6 for use in electric drilling apparatus is controllable both in a constant speed mode and a constant power mode. When the motor is being used for normal drilling operations a switch 3<SP>1</SP> is coupled to the elongate contacts 9, 10 and switch 30 is closed to ehortcircuit thyristor 24. Power control is effected by movement of the contact 3<SP>1</SP> over the fixed contacts 9, 10 which movement alters the setting of potentiometer 14 to alter the firing angle of thyristor 15 to supply power independent of loading to the motor 6 in the range from zero to full half-cycle conduction. When the drill is to be used for driving attachments and constantspeed operation is required, contact 3<SP>1</SP> is moved to contacts 9 and 11 thereby shorting out thyristor 15 and switch 30 is opened. Potentiometer 22 is set to provide a required-motor speed and this voltage is compared with the back e.m.f. of the motor to fire thyristor 24 at points in the appropriate half-cycles to provide constant speed operation.
