Title: Improvement in ice skating rinks
IPC: F25C3/02
Filed: 1927-05-25
Abstract: 279,025. Funk, G. C. Oct. 16, 1926, [Convention date]. Ice-surfaces, making and maintaining; brine, circulating through chambers.-A skating rink floor adapted to. be raised or lowered in temperature, as described in Specification 292,623, is formed of a number of separate slabs free to expand and contract, and with the conduits for the heating or cooling medium embedded in said slabs. The slabs 19 enclose the conduits 10 and are covered with a foor surface 20. The slabs are floated on a bed 23 of dry sand, which is protected below by a waterproofing layer 24 applied directly to the thermal insulating layer 25, which may be of cork or similar material. The floor tubes of each slab are connected to separate headers 12 by T-fittings 30 closed by plugs 33 allowing for inspection and repair of the individual tubes, the outlet fittings being closed by valves 34. The headers are connected to the mains 13 by bends 35, which slope downwards from the mains and allow the headers to partake of the expansion and contraction movements of the slabs. Air vents 37 leading to the roof are supplied at the highest parts of the supply mains 13. The return main 14 is looped upon itself at the end farthest from supply, and those floor conduits nearest to the supply are connected at their other ends to the most remote part of the return main. The diameters of the supply and return mains vary oppositely so as to ensure an even flow. The first coating of ice is obtained by spraying the floor, thus sealing the joints. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a brine pumping system for effecting quick freezing of the floor, in which the brine is pumped from a tank 45, Fig. 8 (Cancelled), through a refrigerating machine by a pump 51 which delivers through a valve 55 to the supply main 13, the brine returning by main 14 through valve 57 to brine tank. In order that the operation of freezing and heating may be expedited, valve controlled shunt heating and freezing circuits 61, 62, 58 and 58, 47, 48, 50, respectively are provided, so that while the floor is being used for dancing and games, preparation for quick freezing and vice versa may be pursued. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,260,923. Telecentric lenses. SZERSZAMGEPIPARI MUVEK. March 18, 1969, No. 14275/69. Heading G2J. A small distortion telecentric lens system of variable magnification comprises lens members 2 and 3 having an overall convergent lens action, an aperture diaphragm 4 at the focus F of the lens members, an achromatic divergent lens 5 and an achromatic convergent lens 6, the image of an object 1 being formed at 7. The positions of the divergent and convergent lenses may be interchanged to vary magnification Fig.2 (not shown), without greatly altering the distance from the object to the lens 2. The small distortion results from the focal length of lens 6 being greater than that of lens 5, and the distance between the principal planes of these lenses being greater than that between the focus F and the principal plane of lens 5.

A tufting machine 10, whose needle or needles 13 span a width which is only a fraction of the width of a strip of backing material 16, is employed to cover the latter with lines of tufting extending longitudinally side by side, by a method comprising the steps of forming the strip into an endless band, and applying the tufting to the band circumferentially and continuously in the same direction, the band being progressively shifted laterally to the needle or needles. As shown, the ends of the strip are connected together in staggered relationship, when tufting which is begun at the laterally projecting portion 19 of one end, and is continued helically, finishes after two or more convolutions at the laterally projecting portion 30 of the other end. Guiding means in the form of grooves 22 in the throat plate 14 and grooves 26 in the feed rollers 24, 25 are provided to line up the row or rows of one convolution with the row or rows of the previous convolution. The throat plate is also provided with a downwardly hinged guide 27 against which the edge 29 of the band abuts during the first convolution to ensure that the rows are parallel with said edge.

Abstract: 699,527. Electric measuring system. GENERAL ELECTRIC CO., Ltd., and BUCKINGHAM, J. D. Aug. 1, 1952 [June 19, 1951], No. 14569/51. Class 40 (i) A Pirani, gauge for measuring the pressure of a gas comprises a filament coated with a metal that is more resistant to chemical action by air and has a higher electrical resistance than the filament proper. For measuring air pressure the filament may be tungsten or molybdenum and the coating rhodium. Two such gauges, one open to the gas atmosphere and one completely sealed, each containing two similar filaments 7, 8 and 29, 30 respectively (Fig. 3), are connected in a bridge circuit, an initial adjustment being made at one corner by a potentiometer 17, and the pressure for a particular gas being indicated on a scale attached to a galvanometer 21 carrying the bridge unbalance current.

Title: Vacuum deposition apparatus for materials in sheet form
IPC: H01G13/06
Filed: 1964-04-08
Abstract: Vacuum deposition apparatus in which sheets of material are coated comprises a vacuum chamber containing first and second magazines for sheets before and after coating and a mechanism for transferring the sheets from one magazine to the other.  In one embodiment, Fig. 1 (dwgs. not shown), the magazines (12), (16) are formed by angle members (11), (15) attached to rails (7) mounted on a ring (9) supported by and rotatable on a track (6) in the upper part of a cylindrical vacuum tank (1), the lower part containing a vapour source (5).  Holders (13) containing glass sheets (14) are stacked in magazine (12) and the lowest holder is pushed into magazine (16) by a rack (19) operated by a motor driven pinion 21.  The magazine assembly is rotated on the track (6) and the lowest sheets coated. After coating the assembly is stopped, two lowest holders are transferred to magazine (16) by rack (19) and coating is repeated. To facilitate transfer the front and back edges of the holders are bevelled.  A notch (27), Fig. 2, engaging a magnetic latch (28), Fig. 1, ensures the locking of the ring (9) during the transfer of holders. Alternatively the magazines may comprise endless chains (30), Figs. 4, 5, carrying lugs (31) and stretched over toothed wheels (32) mounted on shafts (33).  The holders are attached to the lugs and are moved vertically by motors (36), (40) operating worm and gear arrangements (38), (39) and (42), (43) and are transferred as before.  In an embodiment enabling both faces of the sheets to be coated the holders, having notches (56), Fig. 8, instead of bevelled edges are transferred between magazines by a motor driven rocking frame (46), Fig. 7. This frame rotates on a horizontal axis (45) between and beneath the magazines, the holders being placed on and removed from the frame by the chains 30.  The frame is provided with two sets of fingers (53), (53') the upper set of which coincide with the notches (56) during loading and unloading of the holder and which are moved sideways to maintain the holder in position during rotation.  If only one face is to be coated using this embodiment, each holder carries two sheets. The vapour may be produced by electric discharge between movable electrodes (61) Fig. 10.

[Class 23.] A device for distributing gaseous fluids, more particularly air for ventilation, but applicable also for the treatment of air with various gases and the separation of solid particles from a gaseous current by reducing its speed, comprises a spiral band having its turns opposed to one another and spaced apart to provide throughway passages for the fluid of gradually increasing cross section towards their outlet ends so as to effect a reduction in the speed of the fluid. In the form shown in Fig. 1, one end of the band is anchored at c to an annular plate b surrounding the mouth of an inlet conduit a, the other end being fixed to a shoulder e on an adjustable spindle s arranged at the axis of the conduit. The faces of the band are inclined to the axis, the inclination decreasing from the outer to the inner turns. The turns are so arranged that the projection of the inner edge on a plane at right-angles to the axis forms a flat spiral. The cross section of the passages may be varied by screwing the spindle s into or out of its supporting spider i. In a modification, Fig. 7, the device is attached to a spherical shell m rotatably mounted on a similarly shaped member n. In a further modification, Fig. 5, the spiral is arranged so that its turns are normal to the axis and the band decreases in width from the anchored end.
