Patent GB-2178874-A (GB)
Title: Press-key structure
Inventor: TONG ROCK
IPC: G06F15/02
Filed: 1985-08-09
Abstract: A press-key structure 11, 111, 112 provides the feature of colour change of a liquid crystal element 111 in relation to a change of temperature, caused by a fingertip depressing a press-key on the panel of a calculator. The apparent colour of those press-keys which have not been depressed immediately before remains unchanged. It is believed that this will achieve a beneficial recreational effect for the calculator user. <IMAGE>

Title: Apparatus for filling moulding frames in wet or filter presses
Inventor: HENKE AUGUST
IPC: B28B13/02
Filed: 1985-10-01
Abstract: Metering of concrete into moulds is effected on a volume basis rather than a weight basis. A slider (11) is provided at the discharge of a hopper (1) and an intermediate container (7, 8) of adjustable volume has a shut-off slider (4) at its lower end. A desired amount of concrete can be filled into the intermediate container (7, 8) before the slider (11) is closed and the slider (4) is opened to discharge it into a mould. When relatively small amounts of concrete are required, the intermediate container is not used (see Figure 2) and the two sliders are directly attached with the distance between them substantially shorter than that shown in Figure 1. <IMAGE>

Title: Method for the purification of air or gas streams by a multi-path absorption principle and moving-bed filtering apparatus for performing the method
Inventor: OHLMEYER MANFRED
IPC: B01D53/08
Filed: 1986-10-31
Abstract: Process for purifying air or gas streams, which, in accordance with the multipath sorption principle, are conducted in a transverse direction repeatedly in succession, each time in a separation stage, through a multiple-component moving bed, which is composed of flowable filter or sorption materials, which are passed by gravity into the moving bed. The aim is to improve the overall separation efficiency in the filter material. This is achieved by dividing the gas stream after each separation stage into at least two part-streams and feeding each part-stream, depending on its degree of purification in the first preceding separation stage, to a packed bed of defined degree of loading of the second separation stage, for example a lightly purified part-stream from the first stage is fed to a lightly loaded packed bed of the second stage and, conversely, another more intensively purified part-stream is correspondingly fed to a more intensively loaded packed bed of the second stage. Furthermore, a moving bed filter unit suitable for this process is specified, in which the division of the air flow in the deflection chamber is carried out by means of a continuous guide baffle. <IMAGE>

Patent GB-2196810-A (GB)
Title: Radar receiver
Inventor: SIMPSON WILLIAM MELVIN
IPC: G01S7/02
Filed: 1987-08-19
Abstract: A radar receiver for analysing received signals, particularly C.W. signals [Fig. 2(a)], and extracting timing information, in which the received signals is mixed (7) with a ramp frequency modulated signal [Fig. 2(b)], the swept frequency range being such that the mixer output passes through the passband of a frequency compression filter (15) which complements the frequency sweep to produce a regular pulse output [Fig. 2(c)]. A received pulse-signal [Fig. 3(a)] can then be accommodated by ensuring that the swept mixer output still includes a portion within the filter passband (f4-f3). <IMAGE>

Patent GB-2206586-A (GB)
Title: Polynucleotide probes
Inventor: REEDERS STEPHEN THOMAS
IPC: C12Q1/6876
Filed: 1988-06-30
Abstract: The invention provides compositions and methods for improved identification of individuals and individual members of species, by use of regions of DNA hypervariability found in all cells, otherwise called hypervariable regions, or HVRs, in which the DNA contains tandem repeats. The number of repeats varies considerably from one individual to another. Many such regions of the human genome can be probed simultaneously to display this variability using any DNA or other polynucleotide probe of which the essential constituent is a short core sequence, tandemly repeated at least 3 times. Probing with each of the probes reveals differences in genomic DNA at multiple highly-polymorphic hypervariable regions to produce an individual-specific DNA 'fingerprint' of general use for genetic identification purposes, paternity and maternity testing, testing of the relatedness of individuals and the relationship of one individual to another (i.e. family structure analysis), forensic medicine, the diagnosis of genetic diseases and cancer, assessment of bone marrow engraftment, study of pedigrees of non-human species, and identification of individual members of these species. Probing can be carried out on DNA from any cellular tissue.

IPC: E21B47/18
Filed: 1988-07-06
Abstract: A method of receiving instructions for an implement, for example, a drill string stabiliser, which instructions are transmitted by varying the rate of flow of, or pressure exerted by, the fluid in the bore of the drill string in accordance with one of a plurality of predetermined sequences, comprises the steps of:-   a) monitoring variations in the rate of flow of, or pressure exerted by, the fluid in the drill string; b) comparing the sequence of monitored variations with a plurality of predetermined sequences, each predetermined sequence corresponding to a set of instructions for the implement; and   c) either   i) ignoring the variations if they do not correspond to a predetermined sequence, or ii) if the variations do correspond to a predetermined sequence, executing the instructions which correspond to that sequence.     The drill string stabiliser comprising a mandrel, slidably mounted within an outer casing; one or more pads movable between a retracted position and one or more extended positions; means monitoring the rate of flow of, or pressure exerted by, the fluid in the drill string in use; and means which, when activated, seal the stabiliser to restrict or prevent the flow of fluid through it; the arrangement being such that, with the sealing means activated, the exertion of a predetermined amount of pressure by the fluid causes the mandrel to slide within the casing, and the pad or pads to consequently extend.

Title: Piston for a master cylinder
Inventor: ISHIWATA ICHIRO
IPC: B29C65/02
Filed: 1989-01-30
Abstract: A plastics piston 50 for a master cylinder comprises a first moulded member 51 having a reduced diameter portion 54 received in and welded in an enlarged bore portion (60) of a second moulded member 52, so as to define a sealing ring mounting groove (63) on the peripheral surface of the reduced diameter portion 54 between the end face of the second member 52 and a step surface on the first member 51. Superfluous welding resin (P) is prevented from leaking into the mounting groove (63) by providing welding vents in the form of a space defined between the co-operating peripheral surfaces of the portion 54 of the first member and the bore portion (60) of the second member (52). and a gap (G) defined between the inserted end of the portion 54 of the first member 51 and the bottom 60a of the bore portion (60). The construction of the piston prevents the generation of parting lines along the bottom of the mounting groove (63) and thereby provides a superior seal effect. <IMAGE>

Title: A collapsible container
Inventor: GOYMER MAURICE FREDERICK
IPC: B65D77/06
Filed: 1990-04-12
Abstract: An intermediate bulk container 50, comprises four panels 51, forming the sides thereof on a pallet base 52.
