Patent EP-0111363-A2 (EP)
Inventor: VAN DOORN ANTHONIE
IPC: E05B35/08
Filed: 1983-11-30
Abstract: In a change-key lock (Fig 1) there are two packs of levers 5A,5B meshing with respective packs of rotary tumblers 10A,10B. The bolt 1/2 carries two stumps 3A,3B which can be withdrawn into notches 13A,13B in the rotors 10A,10B when the latter are aligned by a double-bitted key lifting the levers 5A,5B. The pivot pins 11A,11B for the rotors are carried by a shiftable plate 12 (Fig 3), normally locked by a lever 27. To reprogramme the lock the existing correct key is first used to align the rotor notches 13A,13B with the stumps 3A,3B; an auxiliary "change" key inserted to keyhole 31 then lifts the lever 27 and shifts the plate 12 to carry the rotors out of engagement with the levers and pass the rotor notches over the bolt stumps; the existing correct key is replaced by the new key which sets the levers to correspondingly new positions; and the "change" key is turned back to re-engage the rotors with the levers in their new positions. In another embodiment (Fig 7) designed especially for safe deposit lockers the bolt is split into two portions 50/51 and 52 controlled by separate sets of tumblers 53C and 53A/53B requiring the use of two different keys, tumbler set 53C being reprogrammable independently of tumbler sets 53A/53B.

Abstract: Certain substituted anthracene-type compounds have been found to be useful as isotropic dyestuffs in guest-host combinations with nematic, cholesteric and smectic liquid crystals and other well-known dichroic dyestuffs. By "isotropic" it is meant that the disclosed dyestuffs have optical order parameters (S) very close to zero. Use of the disclosed isotropic dyestuffs with additional well-known dichroic dyes in liquid crystal display devices, provides displays which alter between one colored state and another, depending upon the presence or absence of an electric field across the display.

Abstract: An alloy is made of a first material and a second material which has a substantially lower melting point than the first material, by (a) forming from the first material a body which has multiple fine interstices; (b) pouring the second material in the molten state around the body formed from the first material; and (c) allowing the resultant mass to cool. Thus, in the parts of the resultant mass in which the body formed from the first material was originally present, an alloy mass comprising the first metal and the second material alloyed together is made. Optionally, the body made from the first material may be preheated, desirably to a temperature higher than the melting point of the second material; and optionally the molten second material may be pressurized so as to enter into the interstices of the body. The first material may desirably be, for example, tungsten, cobalt, chromium, titanium, iron, nickel, silicon, manganese, copper, niobium, tantalum, vanadium, gold, silver, aluminum, molybdenum, zirconium, or zinc; and the second material may desirably be, for example, aluminum, magnesium, copper, lead, tin, or zinc.

Abstract: A sterile shaped prosthetic device, suitable for insertion into a mammalian body, is at least partly composed of a bioresorbable material that is digestible by macrophages, its surface properties favor the attachment and adhesion of fibroblast cells capable of producing collagen for organized connective tissues, and the material itself or its degradation products can induce in vivo the formation of new capillary vessels (termed a "vasotropic" effect herein). Preferred prosthetic devices have through passages, the interspatial dimensions which are sufficient to permit several layers of mammalian cells to form within each passage. The invading fibroblast cells commence formation of collagen leading to connective tissue while macrophages and extracellular enzymes degrade the material, and newly formed capillary vessels penetrate the prosthesis and provide blood containing oxygen and nutrients which further the formation of organized tissue around as well as within the prosthetic device.

Abstract: A boiler safety valve installation with a safety valve 2 discharging relief steam through an upstand 10 into a separately supported vent pipe 12 (Fig.1). The upstand discharges through a belled nozzle 24 of approximately 30° (0.5 steradian) included angle into the vent pipe 12 thereby, on discharge of relief steam, inducing a sub-atmospheric pressure in the space intermediate the discharge nozzle and the vent pipe and lessening the risk of escape of steam at a sliding junction between the upstand and the vent pipe. In installations where the relief steam flow reaches supersonic velocity at discharge from the belled nozzle 24 the vent pipe diameter is constricted by about 5% - 10% at a zone 34 downstream of the discharge nozzle 24 to produce a shock front and reduce the velocity to sub-sonic, thereby reducing the frictional flow loss affects whilst economising in vent pipe size without causing a build-up of back pressure in the space intermediate the discharge nozzle and the vent pipe.

Abstract: A thermosensitive recording label includes a thermosensitive color-forming layer disposed on one side of a substrate and a heat reflecting layer disposed on another side of the substrate and a delayed action adhesive disposed on the heat reflecting layer. The thermosensitive recording label may be manufactured and used without a backing sheet, thus considerably reducing the weight and volume of the label. In use, the thermosensitive recording label is drawn from a roll or stack and the delayed action adhesive activated by a heat lamp, or the like, to place it in a tacky condition for placement on goods. The heat reflecting layer disposed between the delayed action adhesive and the thermosensitive color-forming layer prevents activation of the color-forming layer during heating of the delayed action adhesive.

Abstract: A particular class of triarylmethane leuco dyes are useful in analytical compositions, elements and methods. These leuco dyes are tri-substituted methane compounds having one or two aryl moieties and, correspondingly, two or one aromatic heterocyclic moieties attached to the central methane carbon atom and which, upon interaction with hydrogen peroxide, provide dyes having a maximum adsorption at a wavelength equal to or greater than 600 nm. Particularly useful leuco dyes have the structure:wherein R is a 5- to 15-membered aromatic heterocyclic moiety, and R' and R" are independently open chain or cyclic amines. These compounds are useful for providing detectable dyes in compositions and elements useful for detection of hydrogen peroxide or other analytes which react to produce hydrogen peroxide in liquids, e.g. biological fluids.

Abstract: Method and apparatus are disclosed for producing various materials and products of a thermoplastic nature. In the method, thermoplastic material is subjected to a high intensity mixing and melting step to form a material which is a non-flowable and self-sustaining mass, having a temperature low enough to prevent it from being readily flowable, in a subsequent step, the method involves placing the material between a fixed rigid surface and a moving rigid surface to force air from the mass and to densify, compress and convert it to a flowable form whereafter it is passed through a restricted opening. There is provided a combination of a high inten- s i ty mixer and melter in which the product produced is then fed into a gear-pump where the material is passed between a fixed rigid surface and a moving surface. Higher output speeds can be obtained using the method and apparatus compared to conventional extrusion techniques; in addition, materials not readily processable by conventional extruding operations can be processed.
