Title: Improvements in or relating to illuminated signs
IPC: C09K11/04
Filed: 1965-10-13
Abstract: 1,129,981. Sign formed from luminescent elements. SAINT-GOBAIN TECHNIQUES NOUVELLES. 13 Oct., 1965 [13 Oct., 1964], No. 43427/65. Heading G5C. [Also in Division C4] A self-luminous sign is formed by a plurality of glass bulbs each filled with a radioactive gas and coated on the inside with a luminescent substance, the bulbs may be arranged to form the character to be displayed, or the surrounding background to the character. Each bulb is filled with tritium and its filling end sealed in an epoxy thermosetting resin block, which is mounted, using a push fit, in a suitable aperture at the focus of a parabolic reflector of e.g. aluminium or glass. The resin block may be opaque or transparent. The reflectors may be held, by flanges on their front, against a transparent face plate. The reflectors, and their immediate surround, may form the only opaque parts of the screen, so that the characters they form show up as dark areas when the screen is back-illuminated, e.g. by an electric lamp mounted behind the screen. Alternatively the lamp may be in front of the screen. The screen may also carry a luminescent phosphor of slow decay, so that upon failure of an associated electric light source, the brightness of the screen falls only slowly to the level of the self-luminous units.

Abstract: 966,243. Spacing overhead conductors. ANDRE RUBBER CO. Ltd. Dec. 3, 1962 [Dec. 5 ,  1961], No. 43477/61. Heading H2C. A device for spacing conductors of an overhead transmission line comprises a rigid hub having a number of cavities, each with an opening at its periphery, plurality of arms each having at one end a knob, similar in shape to but smaller in dimension than the cavity in which it is housed, and an elastomeric material at least partly embracing each knob in each cavity. As described, each of four arms 24 has at one end a conventional cable clamp 30 and a knob 25 at the other, a neck 29 being formed between the arm and the knob. The knobs are placed inside four symmetrically disposed cavities 13 of a hub 10 comprising plates 11 and 12 bolted together. The abutting faces of the plates 11 and 12 have corresponding recesses 20 which form the cavities 13 and peripheral openings 19 leading to the cavities through which the arms 24 extend, openings 19 being such that a clearance is provided between each neck 29 of the arms and the wall of the corresponding opening 19. Resilient movement of the arms is achieved by making resilient joints between cavities and the knob housed inside them by surrounding the knob by an elastomeric material 26 in the form of a continuous shell which is compressed by the wall of the cavity aided by the bolts 27. If desired the elastomer 26 may be cemented or bonded to the wall of the cavity or to the knobs or to both by heating before or after the assembly of the device.

Abstract: 1392972 Liquefying or separating gases PETROCARBON DEVELOPMENTS Ltd 17 Sept 1973 [25 Sept 1972] 44195/72 Heading F4P  A process for coding a feedstock, e.g. for liquefying natural gas in line 14, comprises cooling and partially condensing a compressed mixture of gases from line 22 in heat exchanger 2, dividing the partially condensed mixture into two portions, one of which leads to separator 4, and the other of which by-passes the separator 4, combining the uncondensed vapour from separator 4 with the by-pass portion before cooling the combination in heat exchanger 6 to effect further condensation and separating out a second liquid condensate in separator 8, and expanding at 26, 32 the first and second liquid condensates from separators 4, 8 to provide streams of refrigerating liquid which pass back through exchangers 6 and 10 respectively. Valve 42 controls the ratio between the divided portions of the mixture partially condensed in exchanger 2. Condensate in line 44 produced by cooling the feed mixture to line 22 to remove the heat of compression thereof is sub-cooled in exchanger 2 and then expanded at 40 to pass back through exchanger 2 as refrigerating fluid. The compressed gas mixture can be separated into two portions before entry to exchanger 2, the valve determining the ratio of the portions being controlled by means sensing the temperature of the gas being liquefied between exchangers 6 and 10 (Fig. 2, not shown). The feedstock may be the compressed mixture of gases, whereby the process becomes one of separating the mixture by successive cooling, and in this case the condensed portion from each separator can be expanded and fed back through the exchanger in which it was formed without the need for sub-cooling in the next coldest exchanger.

Overlying each zone is an opaque peelable strip such as 42. In use, the control agency peels off strip 42 on a Monday, for example, and immediately records the exposed intelligence combinations thereunder on to recording-playback apparatus 26-36 which, together with secondary complexes 54, 56, 58, are associated with automatic telephone answering equipment. Individual organisations such as 14, 16, 18 in communication with the complexes 54, 56, 58 thus have access to this information and can relay it to game participants such as 60 to 78 who have purchased the usual BINGO playing slips from the organisations. This procedure is repeated until a participant declares himself a winner. In a modified arrangement, the individual organisations themselves record the information, receiyed from the control agency, on to automatic telephone answering equipment with which the game participants communicate directly.
