Patent GB-2086852-A (GB)
Title: Boxes
IPC: B65D5/44
Filed: 1980-11-12
Abstract: A box suitable for vegetable produce comprises a unitary blank of corrugated cardboard having a row of hinged panels which form side walls (10 and 12) and end walls (11 and 13). Base panels (16, 17, 18 and 19) are hinged to the walls and are folded inwards to form a base. Each of the two lower base panels (16 and 18), connected to the side wall panels, is formed with an opening (28). A wooden strip (32) constituting a stiffener extends through those openings. End portions of the stiffener overlie parts of those two base panels adjacent to the side balls, while a central portion of the stiffener extends beneath parts of those panels further from the side walls. Top flaps (25) can be bent inwards and interlocked to stiffen the upper part of the box. <IMAGE>

Title: Liquid crystal display device
IPC: G09F9/30
Filed: 1980-12-01
Abstract: A twisted nematic liquid crystal display device comprises a first substrate (14) having electrodes (12) on one surface and a first polariser (16) on the opposite surface, these electrodes being in contact with a twisted nematic liquid crystal layer (11). A second polariser(15) has electrodes (13) on one surface which is in contact with the liquid crystal layer. A reflective second substrate (17) is in contact with the opposite surface of the second polariser. This arrangement, by reducing the distance between the liquid crystal layer and the reflective surface, reduces the formation of shadow images when the planes of polarisation of the polarisers are parallel to one another to form a clear or white display on a black or dark background. <IMAGE>

Title: Animal dressings
IPC: A61D9/00
Filed: 1981-02-14
Abstract: An animal dressing in the form of a tail bandage, particularly for horses is in the form of a resilient tubular element (13) having elasticated ends (14, 15) and tapes (16, 17) at one end for attaching to the animal's harness or for tying around the root of the tail. An applicator device in the form of a substantially rigid tube shaped at one end to fit over the horse's rump is provided. The applicator tube has a lip (19) at the end remote from the shaped end (20) for retaining the tubular element fitted onto the applicator from the shaped end. Introduction of a horse's tail through the applicator is simplified by its rigidity and enlarged diameter in relation to the natural diameter of the dressing element (13) and the applicator can be withdrawn in a direction from the root towards the tip of the tail whilst retaining the dressing element in position on the tail allowing it to close by its natural resilience to hold the tail firmly. <IMAGE>

Title: Spectrum analyzer
IPC: G10L19/02
Filed: 1981-03-05
Abstract: A spectrum analyzer, e.g., for telecommunication application, includes an input A to D converter (AD) for converting an input analog signal to corresponding binary words, these words then being fed via a buffer (PS) and a multiplexer (MX) to a digital filter (DF). Under the action of a control circuit (CS) the filter (DF) is fed with a series of different submultiples of a clock signal. For each submultiples the filter (DF) is also fed into a corresponding set of filter constants from a memory (PF). Spectrum analysis is made by changing the frequency of the clock submultiple signal to the filter and simultaneously supplying the corresponding filter constants from the memory while ensuring that the centre frequency of the filter passband remains constant. <IMAGE>

Title: Method of making a transformer or like core from amorphous strip metal
IPC: H01F41/02
Filed: 1981-08-11
Abstract: The invention relates to a method of making a magnetic core from amorphous strip material for use in a transformer or similar electrical induction apparatus. In accordance with this method, a continuous strip of non-annealed amorphous metal is wound around a mandrel to form an initially round core which thereafter is clamped in a predetermined way and cut entirely through one transverse section thereof while a rust inhibiting liquid coolant is applied thereto. The resulting unconnected strips are then separated into a number of groups which are assembled together in a predetermined manner to form a substantially oval core. This core, in its final shape, is annealed and simultaneously subjected to a magnetic field of predetermined strength. <IMAGE>
Patent GB-2228163-A (GB)
Title: Frequency hopping data transmission
Inventor: ALEXIS ROGER PIERRE JOSEPH
IPC: H04B1/713
Filed: 1981-08-18
Abstract: A data transmission system suitable for military applications comprises a number of networks each including a number of transmission-receiving stations. Each network uses a transmission channel for a brief period only and then jumps to another frequency in a set of frequency channels that is available to the system. No two networks operate on the same channel at any one time. The system provides a solution to the problem which occurs when a remote network transmits on a channel used by another network in the subsequent time slot. The propagation delay may cause interference on the second network. The system, however, overcomes this by dividing the set of channels into sub-sets and successive frequencies channels adopted by the networks are taken from the sub-sets in succession. In one version frequency gaps are incorporated in the sub-sets so that on any one occasion the set of frequencies used by the networks include no two adjacent channels.

Title: Liquid level indicator
IPC: G01F23/02
Filed: 1981-09-04
Abstract: An indicator for providing an indication of the level of liquid in a container, for example the reservoir of a steam iron, comprises a transparent cover (11) fitted externally to the wall (3) of the container, and defining a chamber (17) between the cover and the wall, which communicates with the interior of the container through openings (13) in the wall such that the level of liquid in the chamber corresponds with that in the container. The cover (11) is conveniently secured to the container wall by resilient projections (12) which hold a peripheral region of the cover in liquid- tight contact with a co-operating sealing surface, Fig. 2. In another embodiment, Fig. 5, the projections (12) are omitted and the cover (11) is ultrasonically welded at (18) to the wall. <IMAGE>

Title: Methods and apparatus or encoding and constructing signals
IPC: G10L25/00
Filed: 1979-03-29
Abstract: Where a signal is represented by a succession of first and second signals representing respective characteristics of portions of the signal waveform and the first and second signals are drawn from respective sets of primary symbols, the apparatus and methods described may be used to effect a reduction in the number of symbols used. First signals in the form of quantised durations of half cycles of a signal to be encoded are derived by zero logic 12 and second signals in the form of a number of events in a half cycle are derived by event logic 13. On application to a map circuit 15, the number of secondary symbols required in a set capable of representing each half cycle is reduced compared with the number of primary symbols (quanta and events). Methods and apparatus for reconstructing signals encoded by secondary symbols are also described.

Title: Removing contaminates from a well fluid and well system
Inventor: OLIVER JOHN E
IPC: E21B21/06
Filed: 1983-08-26
Abstract: A process for removing solid contaminates from a high density, salt-type aqueous drilling/completion packer fluid prior to its introduction into the well bore and for removing contaminates such as drilling mud and fluids from the well system prior to the introduction of brine to maintain the brine in a solids free state. To remove the solid contaminants, a small effective amount of an alcohol and a surfactant are added to the brine. After the solid contaminates agglomerate, the solids are separated, leaving the brine in a substantially solids-free state. To remove the contaminates from the well system, treated water is prepared with a surfactant and alcohol admixed in clean water. Without interrupting circulation, the treated water displaces the fluids and drilling mud within the well system. Circulation of the treated water continues until substantially all of the contaminates are carried in the circulated treated water. The treated water may be preceded or followed by another fluid which assists in removing the contaminates. The solids-free brine is introduced into the well system to displace the treated water without exposure to the contaminates.
