Title: Building block
Inventor: TATTERSALL R F
IPC: E04B2/02
Filed: 1992-04-22
Abstract: A building block 2 comprises a perforated body 4 of which 50-70% of the cross sectional area is perforated and the overall compressive strength of the block is at least 2.8 N/mm<2>. A plurality of perforations 8 disposed immediately adjacent its surface reduce the transmission of moisture into the block 2. A building block 2 comprises a channel 8 or channels 8 located just beneath the surface of the block. At least a wall of channel 8 is formed by a web 10 which can be removed to expose the channel 8. Service pipes or cables can be located within the channel, once it has been exposed. The block is made by adding combustible material eg. sawdust, to the block mixture, which leaves voids in the block structure after firing. The combustible material represents at least 38% of the pre-fired volume of the mixture. Regions 6 may be filled with heat insulating material, eg. expanded polystyrene. <IMAGE>

Title: Improvements in or relating to a camera apparatus
Inventor: VELEMA JAN H
IPC: G03B17/24
Filed: 1993-02-17
Abstract: A camera is adapted to create a composite photograph of a "customer" together with an image of a "celebrity". The image of the celebrity is initially present upon a transparency 7 in the form of a positive image on a totally opaque background. The apparatus includes a projector to project the image present on the transparency on to a film stock and subsequently to expose the film stock through a mask to the customer. Thus the image of the customer impinges on the film stock. The mask has an opaque area corresponding to the area of the film stock exposed when the image present on the transparency is directed on to the film stock. <IMAGE>

Title: Applicator with additional means for retaining liquid by capillary action
Inventor: JOULIA GERARD
IPC: A45D34/04
Filed: 1994-12-05
Abstract: There is disclosed a flexible applicator which is suitable for applying nail varnish which comprises a brush applicator (32) and a retaining means (4) which lies adjacent to the applicator (32) in the region where the brush applicator (32) joins the holder (3). The retaining means can be an elastic element consisting of a filament wound like a spring.

Title: Evaluating thin-film multilayer structures by X-ray diffraction
Inventor: TAKEMI MASAYOSHI
IPC: G01N23/20
Filed: 1995-05-19
Abstract: Thin-film multilayer structures, e.g. InP/InGaAs multiquantum well (MQW) structures 21, 22 are evaluated as to the thickness and composition of metamorphic layers 23 - 27 formed at the heterointerfaces by calculating X-ray diffraction patterns of assumed structures (a) with no such layers; (b) with layers of predetermined composition and thickness; and (c) with layers having predetermined fluctuations of composition (or thickness); and varying the predetermined parameters to match corresponding aspects of the calculated diffraction pattern with those of the measured pattern and thereby estimate the actual value of those parameters. The matches are (a) an overall pattern match, which indicates an ideal structure with no metamorphic layers; (b) coincidence of the positions of the main and satellite peaks in the respective patterns, which indicates the average layer composition and thickness; and (c) coincidence of the interference fringes around the satellite peaks, which indicates the fluctuations of composition (or thickness) in the layers. <IMAGE>

Title: Store checkout
Inventor: KEATING BRIAN
IPC: G06K7/10
Filed: 1996-03-20
Abstract: A store checkout system has a plurality of portable handheld bar code laser scanners used by customers to scan bar codes on items to be purchased. Then the scanner is plugged into a downloading base unit whereupon all of the information stored in the scanner is downloaded into a store computer system which determines whether the purchases are to be re-scanned and checked by a store assistant on the basis of one or more criteria, e.g. predetermined check frequency levels assigned to a particular customer, which can be increased or decreased according to the accuracy of the particular customer's self-scanning. Adjustment of the frequency of checking can be made, dependent upon the success of the self-scanning by the customer. The system may judge whether any discrepancies identified during checking are acceptable on the basis of preselected parameters. The likelihood of a customer's purchases being checked may be adjusted on the basis of additional preselected parameters. Additional criteria may be specified in addition to demonstrating satisfactory usage, for permitting reassignment to a lower average check frequency. When a customer is reassigned to a higher average check frequency level, no check may be made during a subsequent visit.

Title: Process for manufacturing cellulose moulded bodies
Inventor: KALT WOLFRAM
IPC: D01D4/02
Filed: 1995-06-26
Abstract: The invention concerns a process for manufacturing cellulose moulded bodies in which a suspension of cellulose in an aqueous solution of a tertiary amine oxide is converted to a mouldable solution which is extruded using a shaping tool and introduced into a regeneration bath. The process is characterised by the fact that at least a portion of the materials in the apparatus and pipes used for transporting and processing the solution and in contact with the mouldable solution contains at least one element from the group titanium, zirconium, chromium and nickel in elemental form or in the form of compounds, to a depth of at least 0.5 m, preferably more than 1.0 m, and in a proportion of at least 90 %; the rest of the composition must not contain any of the elements copper, molybdenum, tungsten or cobalt. By using specific elements and compounds in this way, it is possible to prevent or limit exothermic decomposition reactions in the cellulose solution.

Title: Mirror mount for a laser resonator
Inventor: HOWELLS STUART
IPC: G02B7/182
Filed: 1996-05-22
Abstract: A laser mirror 4 is held by a spring pressure plate 7 against a platform 2 formed on a body 1. A collar 5 is located about the mirror 4 and the platform 2.

Title: Acoustic fluid flowmeter
Inventor: DISTON ANDREW STEPHEN
IPC: G01F1/66
Filed: 1996-06-07
Abstract: A fluid flow meter comprises a pair of transducers 8,9 spaced apart in the direction of fluid flow. A transmitting system causes acoustic signals to be transmitted in both directions through the fluid by the transducers. A processor determines information relating to the fluid flow by monitoring the time of flight of acoustic signals received by the transducers. Part of the space between the transducers defines a flow path consisting of a flow structure 5 having at least one fluid flow passage (13-18 Fig 3A) which extends axially in the direction of fluid flow. The fluid flow passages (13-18) includes, in one example, slots (13A-18A) positioned to as to attenuate at least one asymmetric acoustic propagation mode. A connecting passage (23, Fig 4) may connect the fluid flow passages (13-18) to each transducer so as to reduce the propogation of at a least one asymmetric acoustic propogation made relative to the propogation of acoustic plane waves along the passages. A connecting passage (24, Fig. 5) may connect the fluid flow passages to each transducer so as to allow only plane acoustic waves to be transmitted there through so as to prevent the generation of asymmetric acoustic propgation modes.
