Abstract: Apparatus and a method are provided whereby snow is made in an indoor environment over extended periods. Within the indoor environment temperature and humidity conditions are set up to enable snow to be produced by a spray of water from a system including a tank 38 and pump 39. Such conditions may be maintained for an extended time by the use of thermal storage means in the surface to which the snow is applied. The thermal storage means is cooled to a low temperature by coolant in turn cooled by refrigeration apparatus which includes an evaporator unit 26 and condenser unit 27. The thermal storage means uses a mass of relatively high conductivity material through which the coolant is circulated and the coolant is used to cool and dry air to be discharged into the indoor environment.

Abstract: 1,089,456. Casting processes; continuouscasting machines; casting composite ingots; consumable electrodes; rolling. LA SOUDURE ELECTRIQUE AUOTGENE, PROCEDES ARCOS. Oct. 22, 1964 [Nov. 28, 1963], No. 43050/64. Headings B3F, B3M and B3R. In an ingot-manufacturing process of the type in which a consumable electrode comprising compacted metallic powder penetrates continuously into electrically-heated molten slag 3 covering molten and solid metal 15, 4 in a watercooled mould 5, the electrode is formed by passing a wire 14 at constant speed through a container 19 where it is coated with metallic powder 13 compacted by a rotating feed screw 20. Members 5, 14 are connected to an electrical supply 7, and a protecting gas-filled shroud 23 may be provided for the electrode. If the powder is magnetic, agglomeration and compacting may be achieved by passing the electrode between electromagnetic coils after its emergence from the container 19, Fig. 11 (not shown). Mixing of the molten materials may be improved by using a medium frequency heating supply (e.g. 300 cycles) and/or by using a non-magnetic mould surrounded by an electromagnetic coil, Fig. 18 (not shown). Ultrasonic vibrations may be used if a fine crystalline structure is desired. The electrode may comprise metal strip having compacted powder on one or both sides, and compaction may be performed by passing the powder-coated wire or strip between suitably-shaped rollers, Figs. 7 to 10 (not shown). In another modification, Fig. 12 (not shown), the electrode is entirely composed of compacted powder. The arrangement of Fig. 5 may be modified to perform continuous casting of lengths of metal extracted from a bottomless mould by driving rollers therebeneath, Figs. 13, 15 and 17 (not shown). Fig. 19 shows an arrangement for producing a composite ingot. Reference is also made to a mould closing around metallic parts to be joined and to a mould comprising several parts of which only some are cooled to join other uncooled sections. Typical figures are given for electrode dimensions, composition, fusion speed and energy consumption, and a comparison is made with various prior art electrodes.

Filed: 1969-12-22
Abstract: For lengthwise transit of a film strip from one frame at a fixed station, to bring any other selected frame thereto, a counter is charged with the initial number of frames that must pass the station. A pulse is produced as each frame passes the station, to count down the counter. The pulses are also integrated to produce a true strip speed signal. With the use of the charge on the counter, a demand value signal is produced, corresponding to a constant fast velocity for all frames that must pass the station in excess of a predetermined number, and therebelow, to a decreasing velocity proportional to number of frames still to pass. The strip drive is energized according to the difference between true and demand values, in a manner tending to maintain that difference at zero.

Title: Method of producing gas-filled discharge tubes, designed as transient protection, for example
Inventor: SCHLEIMANN-JENSEN ARNE

Filed: 1980-10-08
Abstract: Gas-filled discharge tubes for use as transient protection with at least two electrodes, separated by a discharge gap and an insulation body, which is joined to the electrodes and together with them forms a discharge chamber. Sealing of the tube is done at atmospheric pressure and suitable temperature in an appropriate mixture of light and heavier gas for the purpose, after which this gas mixture is pumped out, or other steps are taken so that the gas pressure around the tube becomes lower than atmospheric pressure and is advisedly brought down to an order of 3 kPa or less, while at the same time the temperature is regulated so that the light gas enclosed in the tube - by virtue of the pressure difference between the inside of the tube and its surroundings - permeates through the walls of the tube by diffusion and effusion, while the heavier gas can only permeate the walls to insignificant extent. The gas bleed- out produces reduced total gas pressure inside the tube and the process is terminated when the desired pressure decrease has been accomplished. <IMAGE>
