Abstract: 1,221,068. Valves. AVERY-HARDOLL Ltd. 1 April, 1969 [14 Feb., 1968], No. 7223/68. Heading F2V. [Also in Divisions A4 and G3] A pressure regulating valve 14 which is mounted at or adjacent the inlet of a hose 15 in a liquid dispensing apparatus (see Division A4) and which moves towards its closed position when the pressure at the inlet end of the hose rises above a predetermined value comprises a body 22 having inlet and outlet chambers 23 and 24 and a cylinder 29 in which a piston 28 having a stem 35 is slidable. The stem 31 of the piston engages a valve closure member 27. The piston 28 is urged away from the closure member 27 by a spring 32, is exposed to the atmosphere on the side nearer the closure member and is connected to the interior of the hose 15 on the side opposite the closure member by a tube 33. To enable the valve 14 to act as a shut-off valve controlled by a presetting mechanism, the valve closure member 27 is carried by a stem 34 which carries a piston 36 having an orifice 27 in which is seated a poppet valve 41, the side of the piston 36 away from the closure member 27 being connected to the outlet chamber 24 of the valve by a passage 37 in which there is a flow restriction 38. When the poppet valve is closed, a pressure difference is established across the piston 36 which urges the closure member 27 on to its seat and shuts off the flow of liquid. The normal operation of the pressure regulating valve 14 is not affected when the poppet valve 41 is open.

Title: Improvements in or relating to fluorescent low pressure mercury vapour electric discharge lamps
IPC: C09K11/68
Filed: 1943-05-07
Abstract: 564,449. Luminescent materials. COLE, Ltd., E. K., and EVANS, J. N. I. May 7, 1943, No. 7227. [Class 39 (i)] [Also in Group III] A fluorescent material for use in a low pressure mercury vapour discharge lamp includes a tungstate prepared by heating magnesium oxide or zinc oxide with tungstic oxide in the presence of 2 per cent to 20 per cent of silica in the form of fine particles. The silica is prepared by mixing sodium disilicate solution with a solution made up from ammonium chloride and nitric acid. The silica precipitate is then mixed with the oxides in a ball mill, evaporated to dryness, crushed, and fired for 3 hours at 1,050‹ C. Magnesium or zinc carbonate may be used in the process as they decompose to the oxides in the heating up process. Other fluorescent materials, such as zinc beryllium silicate, may be mixed with the above for colour modification. A small admixture of alkali, such as lithium carbonate, increases the particle size of tungstate if required.

Title: Improvements in radio-control apparatus
Inventor: SOMMERHOFF GERD WALTER CHRISTI
IPC: A63H30/04
Filed: 1954-03-12
Abstract: 774,120. Remotely controlled toys. LINES BROS., Ltd. March 3, 1955 [March 12, 1954], No. 7317/54. Class 132(3). [Also in Group XL(c)] The transmitter for the radio-control of a model boat consists of an oscillator which can be made self-quenching by switching an R-C network into the grid circuit. It is stated that the model boat carries a receiver and a relaycontrolled electric motor which, in the absence of a signal, drives the boat ahead, and on receipt of a continuous signal drives the boat astern. Hence by use of an interrupted signal of equal mark/space ratio, the boat can be held stationary ; whilst variation of the ratio will control the forward or reverse speeds. The oscillator accordingly includes switches S 1 , S 2  in the grid circuit, which, when both are open, prevent oscillation : when S 2  only is closed, provide continuous oscillation, (the circuit operating conventionally) : and when S 1  only is closed, add resistors P, R 2  to the grid leak R 1 , these resistors being shunted by capacitors C 3 , C 4  so that the oscillator will squeg. The time constants may be varied by shorting resistor R 2  with a switch S 3  and by shorting capacitor C 4  with a switch C 4 . With R 2 , C 4  shorted, the circuit is adjusted by the resistor P to give an equal mark/space ratio (boat stationary), introduction of resistor R 2  then reduces the ratio (slow ahead), and the introduction of C 4  (with R 2  shorted) increases the squegging frequency. This signal, it is stated, is selected by the boat receiver to control a different motor, e.g. an anchor winch.

[Also in Group XVI] In an addressing machine, two single marginally perforated strips or two sets of such strips, each comprising two superposed strips, such as 12 and 13 are fed at right angles to one another from trays 10 past the impression position by two pairs of pin wheels 9 carried on intermittently driven shafts 6 and 7, such that the strips 12, impressed by printing plates 1 fed under a table 3 are fed faster than the strips 13 which receive a condensed record of the information printed on the strips 12. The strips 12 are fed in the direction of the printing lines on the plates, while the strips 13 are fed transversely to such lines. The movement of the strips alternate with the movements of a presser head 5, the shafts 6 and 7 being connected by bevel gears and driven through oscillatory driving means as described in Specification 627,572, [Group XVI], such that the strips 13 are moved one line for each impression. Alternatively, the shaft 6 may be driven by an electric motor through a solenoid controlled clutch and stop device, such that the clutch is engaged and the stop device is released by the solenoid on upward movement of the presser head under the control of an electric switch operated by such movement. In a further modification, the shafts 6 and 7 are driven at different speeds by independent motors and solenoid-operated clutches. If two pairs of strips are employed, one of the strips 12 may constitute reminder notices and the other receipts, while the strips 13 may carry, on a single line, condensed records of the information on the strips. 12. The lowermost strip 12 carries a line 15 of carbon or like duplicating material on its upper side corresponding in position and width to the matter to be reproduced on the superimposed strip 13 which carries on its upper side duplicating material extending the whole width of the printing plates ; the next strip 12 is provided with a line 15 similarly to the lowermost strip 12. The duplicating material may be separate carbon-paper strip, a linen shield being provided, in this case, to expose only the line desired for reproduction on the condensed record strip or strips.

The alkaline agent may be an excess of the substituted piperazine, in which case the reaction is carried out in an aromatic hydrocarbon solvent, preferably at the boiling point, or the alkaline agent may be an inorganic alkaline agent, when the reaction is carried out in butanol, preferably at 100 DEG  to 110 DEG  C.  o -Phenoxyethyl halides may be prepared by reaction of the corresponding phenol with excess of 1,2-dihalogenoethane by bringing the mixture to the boiling point, adding a strong base capable of converting the phenol into the basic derivative thereof, boiling the mixture under reflux and separating the o -phenoxyethyl halide formed.  Therapeutic compositions, which may be administered penorally, rectally or parenterally and which act as depressants of the central nervous system and hypotensors, contain as the active ingredient the compounds of formula I, together with a pharmaceutically acceptable carrier.
