Patent GB-2220097-A (GB)
Title: Self-illuminating signs such as house numbers
Inventor: MOINE RENE
IPC: G09F13/04
Filed: 1988-06-24
Abstract: A panel 6 or 7 with characters such as letters or numbers or diagrams forms a sign. This incorporates a means of absorbing light when the surroundings are bright, and emitting light when the surroundings are dull or dark. Thus it can be seen in any ambient light. Parts of the sign can be permanent while other parts can be easily altered. The light can be converted to and from electrical energy. A light-sensitive switch can direct whether the device absorbs or emits light. An extra energy source can be used if insufficient energy has been stored. A transformer can also be incorporated. This device can be particularly useful for a number and/or name and/or message outside a domestic dwelling. As shown, a transparent panel 2 permits light to enter and be absorbed and converted to electrical or other energy in panels 3, 4. A sensor 5 determines whether the ambient light is bright enough for the sign to be read clearly without using the stored energy. Phosphorescent chemical may be employed. <IMAGE>

Title: Geiger-Muller tubes and their manufacture
Inventor: GAIR SALEM ABRAHAM
IPC: E21B47/01
Filed: 1989-07-10
Abstract: A Geiger-Muller tube designed for use in an environment subjected to mechanical shock and vibration has a tensioned anode wire (1) secured between first and second mounts (11, 21) located (12, 22) at opposite ends of the tube envelope (10). The wire tension is adjusted, preferably with a screwible-adjustment means (22, 23, 24) which is locked (*25) in the adjusted position, so that the natural frequency of vibration of the tensioned wire (1) does not resonate with any frequency to which the tube is subjected in use. The adjustment means (22, 23, 24) may be included in the mount (12, 22) via which the envelope is evacuated and back-filled with the ionizible gas, and a gas-tight seal (30) can be provided around this part of the mount (12, 22), for example by sealing off the gas pump tube. However the adjustment means may be designed into another part of the tube, for example using telescopic parts of the envelope whose sliding junction is made gas tight with a flexible seal. Alternatively, the desired tension may be obtained by welding the wire to the first mount (11, 21), passing it through the second mount (12, 22), tensioning it and then crimping it to the second mount (12, 22). <IMAGE>

Abstract: A board game comprises at least one playing surface 10 having at least one golf hole 14 marked on it, each golf hole being marked with means 28, 30 indicating displacement on the golf hole; tokens 15 movable along the surface; and random selection means for selecting a manner by which a player must displace a token across the playing surface. The random selection means may be a direction die (54) Fig 3 to indicate the direction A-F from tee 32 and a distance die 44 which, as shown, corresponds to the 8 iron selected for that player's turn. The dies are kept in a "golf bag" (48) Fig 4. The hole includes hazards which restrict selection. Alternatively, a pair of dice (62, 64) Fig 5 may be used in conjunction with a table I (not shown). Also a different "golf bag" (70) Fig 6 may be used marked to indicate possible distances with a particular club. Further, a "golf bag" (80) Fig 7 may be used with a table II (not shown). <IMAGE>

Patent GB-899027-A (GB)
Abstract: 899,027. Mechanical calculating-apparatus. ROTHSCHILD, M. L. March 3, 1961 [March 17, 1960], No. 7809/61. Class 106 (1). A calculator for use in converting currency, comprises sliding guided scales with columns of numbers, a face-plate covering the scales, a pointer for each scale accessible at the face-plate and windows in the face-plate to expose a number on each column of each scale, and is characterised in that some of the scales include shutters arranged to obturate a column of numbers on an adjacent scale. The value to be converted, e.g. in ú s. d. is set by pointers 14, Fig. 2, moving in slots 15 against scales 16 on the face-plate. The pointers are attached to slides 12, Fig. 3, supported by guides 11, and carrying columns of numbers 13. The converted value, e.g. in Rands/cents, appears at windows 17 in the face-plate. Two of the slides give a direct duo-decimal-todecimal conversion corresponding to pence and unit shillings to cents, and the remaining slides have attached thereto stepped shutters 18, each of which normally obscures the left-hand column of two columns of numbers on its adjoining slide (denoting Rands), but exposes this when a " carry over " is necessary. The reverse face (Fig. 1, not shown) shows the conversion Rands-cents to ú s. d. A modification (Fig. 4, not shown) operates with a curvilinear movement. A further embodiment (Fig. 5-8, not shown) provides an extra scale of numbers on each slide and further windows on the face-plate in lieu of the scales on the faceplate.

Title: Forming machine
Inventor: ISHINAGA NOBUYUKI
IPC: B30B15/00
Filed: 1990-02-09
Abstract: A forming machine for fully enclosed die forging has respective punches 61, 69 inserted into a pair of dies 52, 55 facing each other. The die 55 is supported by one end of a ring member 67 accommodated in a holder 71. The other end of the ring member 67 is disposed wthin a cylinder chamber 85 formed within the holder 71. The ring member 67 has a piston member 75 disposed within it and the punch 69 is supported by one end of the piston member 75. The other end of the piston member 75 is disposed in the above cylinder chamber formed within the holder 71 or a cylinder chamber communicating with the holder 71. When a top slide of a press moves down, the upper die 53, lower die 55 and ring member 67 move down, and this lowering movement of the ring member pushes hydraulic fluid from the cylinder chamber 85 into the cylinder chamber having the piston member 75 disposed therein, thereby moving the piston member 75 upward and the lower punch 69 upward as well to thereby forge a billet 13 between the dies. <IMAGE>

Title: Immobilised polynucleotides
Inventor: DAY PHILIP JOHN ROYLE
IPC: C07H21/00
Filed: 1990-07-05
Abstract: Nucleotides can be linked from a 5'-phosphate residue to a support via a dithio (-S-S-) linkage. Polynucleotides thus immobilised can be used in the polymerase chain reaction (PGR) at which a temperature of 90 DEG C is typically required. The -S-S-linkage can be produced by reaction of a thiolated support with a 5'-(thiol-terminated) polynucleotide. For ease of hybridisation of the immobilised polynucleotide, the sequence to be hybridised should be adequately spaced from the support. The invention is useful in any situation in which a polynucleotide such as DNA is required to be separated as a solid phase from a liquid phase, especially in heterogeneous assays and to isolate products of the PCR.

IPC: B65D17/34
Filed: 1991-07-23
Abstract: In an easy-open lid 10 for a drinks can, where a portion 20 of the lid is displaced inwardly on opening to provide a dispensing aperture 31, an opener tab 15 is secured to the lid by a rivet 13. The opener tab may be rotated about the rivet to seal the aperture. The opener tab comprises a blade 16 which initiates and propagates tearing along a weakened line 21 defining the aperture, and a finger grip portion 19 connected to the blade by arms 18. The can is opened in the normal way, by pulling upwards on the finger grip portion to push portion 20 inside the can, and then pushing the grip 19 back. The opener tab may then be rotated about the rivet to bring the grip 19 over the aperture 31, thus closing it (see Fig 2). The grip has no apertures in it, and is of a similar shape to the aperture 31. The grip may be coated with a material to enhance sealing, and may be tucked inside the aperture on closing to further improve the seal. <IMAGE>
