Abstract: 748,890. Cold-cathode tubes. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 13, 1953 [March 14, 1952], No. 7028/53. Drawings to Specification. Class 39 (1). An electric stabilizer circuit comprises a coldcathode glow discharge tube which works at an abnormal cathode drop, i.e. so that the whole discharge surface of the cathode is covered by the glow discharge. The internal resistance of the tube is kept at a low positive value by special selection of the gas filling and cathode material. The discharge surface of the cathode must be constituted by a homogeneous material, molybdenum, zirconium, tungsten or tantalum being suitable. A suitable gas filling consists of neon with between 0.02 and 0.5 per cent of argon. Other rare gases may be added to this neon-argon mixture. Helium may be added up to a pressure corresponding to a third of the partial pressure of the neon, and krypton and/or xenon may be added up to a pressure corresponding to two thirds of the partial pressure of the argon. The total partial pressures of the argon krypton and xenon must then amount to between 0.02 and 0.5 per cent of the total partial pressures of the neon and helium. A current-voltage characteristic is shown, together with curves showing the effect of the filling mixture on the internal resistance of the tube.

IPC: F24D17/00
Filed: 1961-02-27
Abstract: 946,945. Hot-water supply systems. A. S. W. APPARATENFABRIEK N.V. Feb. 27, 1961, No. 7108/61. Heading F4A. Apparatus adapted to supply hot and cold water to mixing valves located at draw-off points at and remote from the apparatus and also to supply a mixture of hot and cold water of pre-regulated temperature to a tap located at the apparatus and to a tap or taps remote therefrom comprises a cold water inlet pipe 19 having a branch pipe 13, water to be heated flowing from the inlet via a path 1 . . . 4 (Fig. 3), to a gas-fired heating element V whence hot water issues into the pipe 6 which has a branch 18, and hot and cold branch pipes 13, 18 unite in a pipe 10 to provide a mixture of lower temperature than that in the pipe 6. The mixture may be withdrawn via a tap 20 on the pipe 10 or may flow through a pipe 21 branching from the pipe 10 to one or more distant taps 22. A non-return valve 9 prevents backflow of cold water into the hot water flow pipe 6 whilst a control screw M regulates the amount of cold water admitted to the branch 13 and hence the temperature of the mixture drawn from the tap 20 or 22. Taps 14 and 15 connected respectively to the hot water flow pipe in front of the non-return valve and to the cold water inlet form the known type of mixing battery permitting water of any desired temperature to be drawn-off at the outlet U. A pipe 17 branching from the hot water flow pipe in front of the non-return valve conveys hot water to a distant tap 14a which may be associated with a cold water tap 15a supplied from a pipe 16. The gas supply to the burner B for the heater V is controlled automatically in dependence on the pressure drop across a throttle S in the heater inlet pipe by a valve actuated by a diaphragm 24 responding to this pressure drop. The hot and cold water pipes to and from the heater V and to the various taps are connected to a junction block, Figs. 4 and 5 (not shown), in which the various interconnections are made and which houses the control member M, the non-return valve 9 and the throttle S.

Abstract: 702,816. Centrifugal fans. PAILLARD SOC. ANON. March 20, 1952 [May 29, 1951], No. 7190/52. Class 110 (1) In a fan comprising pivoted blades under the control of at least one spring, the centre of gravity of each blade is offset from the pivotal axis so that, beyond a certain speed of rotation, centrifugal force causes the blades to pivot against the action of the spring so as to ensure substantially the same delivery of air for at least two different speeds of rotation. Each impeller blade 6 has a semi-cylindrical ridge 7, the ends of which project from the edges of the blade to form pivots which are journalled in holes 9 in the impeller end plates 1, 3. The blade is urged into the position shown at 6a by a spring 1 which is held by a lug 13 and is bent at one end to fit into a hole 12 in the plate 1. When the impeller speed exceeds a predetermined value the blade is urged by a centrifugal force against the action of the spring 11 into the less effective position shown at 6b, so as to maintain the delivery subsubstantially constant. Movement of the blade is limited by the engagement of a projection with an arcuate slot 10. The separate springs 11 may be replaced by a single spring acting on all the blades through a set of levers.

Filed: 1957-03-06
Abstract: 826,056. Masted lift trucks. YALE & TOWNE MANUFACTURING CO. March 6, 1957, No. 7378/57. Class 78 (3). In a masted lift truck, a pair of clamping arms or forks adjustably attached to the lifting carriage are hydraulically controlled, each by a separate ram, and means are provided for directing fluid to move one ram while holding the other against movement, then moving the second ram when pressure builds up in the first due to its arm or fork meeting the load or an end stop. As shown, clamping arms 10, 11, movable in a guide 14 mounted on the carriage of a lift truck, are controlled by rams 17, 18. Pressure fluid is supplied from a control valve 19 to either of lines 20, 21 to move the arm 10, and a check-valve 22 holds the arm against movement when pressure is cut off from line 21. Springs 27 acting against the fluid pressure on spools 26 in valves 25, 25a, prevent the fluid operating the ram 18 until the arm 10 is obstructed by the load or an end stop, causing a build-up of pressure in either line 20a or line 21a. By-pass valves 33 allow low-pressure fluid to return past valves 25, 25a from ram 18, and check valves 35, 35a hold the arm 11 against movement while the arm 10 is being moved.
Patent GB-983078-A (GB)
Title: Improvements in or relating to sheets suitable for the production of copies
IPC: B41M5/10
Filed: 1962-02-26
Abstract: A sheet suitable for the production of copies without using carbon paper is made by applying to a base sheet two successive coatings. The first coating comprises a colour pigment and a thermoplastic binder, is free of oil and wax and not of itself transferable.  The second coating comprises waxes or similarly-acting substances but not soap, is applied as a liquid but in such a concentration or at such a temperature that it crystallizes, flocculates or solidifies rapidly after application. By this means, penetration into the colour-imparting first coating is avoided, while the second coating adheres to the first and, under writing pressure, tears away part of it and anchors it to a writing sheet.  The base sheet may be opaque or transparent and may be of paper, fleece, fabric, foil of inorganic or organic, natural or synthetic origin, and may be coated over the whole or only part of one or both surfaces.  The binder for the first coating may be a synthetic resin, e.g. polycinyl acetate or polyvinyl alcohol.  This coating may also contain silicic acid, plasticizers and lubricants.  The second coating may be of montan wax acids of their derivatives, e.g. esters, paraffin wax, microwaxes polyethylene, polypropylene or mixtures thereof.  It may be applied as a solution or dispersion cooled to the point of incipient flocculation, or as a melt just above the melting point. The sheet may be cooled, e.g. by air, to cause rapid setting.  If the base sheet is transparent, the completed transfer of the coatings where writing pressure is applied enables the sheet to serve as an original for photo-copying.
