Patent GB-2145515-A (GB)
Title: Crack or strain monitor systems
Inventor: ALLISON IAN MILES
IPC: G01M11/08
Filed: 1984-07-26
Abstract: A crack or strain monitor system 1 for monitoring a structure 8 comprises a pair of optical fibres 2, 3 with light sources at one end of the fibres 2, 3 and light detectors at the other end thereof. The optical fibre 2 is disposed in closer proximity to the structure 8 than the optical fibre 3. Fig. 2 is disposed in a locating body 11 secured to the structure 8 by adhesive. The arrangement is such that the fibre 2 is contiguous with the surface of the structure 8, and is a "crack-sensing" fibre. The fibre 3 is mounted on the exterior of the body 11, and is an "integrity" fibre. In operation, should the "crack- sensing" fibre 2 fail whereby a signal is initiated by an alarm device, the likely cause is overstraining of the structure 8. On the other hand, should the "integrity" fibre 3 fail whilst the fibre 2 remains intact, the likely cause is not overstraining of the structure 8, but instead a spurious fault in the system. The invention has particular applications where operating conditions make it difficult or even impossible to carry out a visual check. <IMAGE>

Title: Lubrication of tablet punches (and dyes)
Inventor: CANNING STANLEY MICHAEL
IPC: C09B67/02
Filed: 1986-07-23
Abstract: Material to be used as a lubricant for preparing tablets is added to the mixture prior to tabletting prior to compressing into tablets. The material consists of plant cells containing oil, or oil-like material contained with the plant cells. These cells will be damaged, releasing the oil or oil-like material, the amount of damage and hence the amount of oil or oil-like material released being dependant upon the pressure between the tablet punch and dye.

Title: A method and apparatus for applying decalcomanias
Inventor: MARSHALL KENNETH
IPC: B44C1/17
Filed: 1986-07-29
Abstract: This is an improvement on the method described in Specification G.B. 2 141 384A in which a thermoplastics sheet carrying decalcomanias was perforated to permit application of portions of the sheet to articles. In the improved method an unperforated sheet (2) of thermoplastics carrying printed design motifs (4) is held across an aperture (15) in a table (13) by a suction ring (16) which encircles the aperture. A hot article, such as a plate (38), to be decorated and a domed pad (33) are brought against the held portion of the sheet from opposite sides to sandwich the sheet, and the pad and article are then moved together relative to the table (13) to sever the sheet around the edge of the article. The severing of the sheet arises from the softening of the sheet by the hot article, and this method of severing produces a neat edge to the severed sheet coinciding with the edge of the article. <IMAGE>

Title: Cement compositions
Inventor: MAJUMDAR AMALENDU JYOTI
IPC: C04B7/153
Filed: 1988-10-12
Abstract: The advantages of high alumina cement (early strength, resistance to sulphate attack) are preserved and its disadvantage (weakens with age) is solved by mixing it with a material such as ground granulated blast furnace slag which encourages formation of gehlenite octahydrate in preference to or to the exclusion of the harmful 'conversion' (weakening) reaction. The composition may be placed as a floor screed. <IMAGE>

Title: Golf club head
Inventor: LACOSTE RENE
IPC: A63B53/04
Filed: 1988-12-22
Abstract: A golf club head is moulded in a mould in a single operation to give it a predetermined shape and volume. However, the weight of the head is predetermined during moulding by the introduction into the mould of movable parts (3, 3a, 4, 4a) which are withdrawn from the mould and from the head before removal of the latter from the mould and which create cavities of a greater or lesser depth. Thus heads may be made in the same mould, of the same material, but of different weight characteristics. The hole(s) may be plugged and/or wholly or partly filled with inserts. The heads may be formed of polyurethane and the cavities may be filled with expanded foam sealed in with epoxy resin. Reinforcing fibre may be used in the head portion. <IMAGE>

Abstract: The variable colour lamp 10 employs two gases, eg. neon and mercury, having different ionization potentials which are sealed in a lamp tube 11 together with an opposed thermionic cathode 14 an electron permeable anode 15 which are spaced apart by several mm, to several cm., and wherein by varying the applied voltages thereto the light emitting ratio of the two gases is varied giving different color light generation. In an example, with a filling of 10<-2>-10<-4> torr Hg and 10<-1>-10 torr Ne and a voltage between anode and cathode of 20 volts, blue light is emitted mainly from Hg the vapour, whereas with a voltage of 25 volts pink light is emitted when the Ne emission is added to that from the Hg vapour. The lamp envelope may be clear or may be coated with a phosphor. In an alternative arrangement the relative duration of "pulses" corresponding to the two voltage levels is varied to control the colour of the emitted light. …<IMAGE>…
