Patent GB-2214258-A (GB)
Title: Support for wire or pipe
Inventor: GRILLET CHRISTOPHER
IPC: F16B2/24
Filed: 1987-12-30
Abstract: A fastener for supporting an elongate member, such as a wire rod (16), from a masonry nail (12) driven into a wall (10), comprises a thin strip of material (14) having a slotted aperture (18). The strip (e.g. of stainless steel) is bent about one side of the nail so that the rod (16) can pass from one end of the aperture under the other side of the nail and out through the other end of the aperture. Two such fasteners (16, 16a, Fig. 5) may be used in adjoining pairs but facing their respective nails (12, 12a) in opposite directions. The aperture (18) may be open on one side and may be C-shape. <IMAGE>

Title: Rotary drum filter
Inventor: PITTWOOD ARTHUR STANLEY
IPC: B01D33/80
Filed: 1988-03-29
Abstract: A perforated filter drum 1 rotates about an inclined axis 2, a solids-liquid mixture is fed to the bottom end through duct 5 and drained solids are discharged at upper end outlet 8. Liquid draining through the drum wall is mainly collected in collector 10, but should the perforations in the lower part of the drum become blocked then more liquid will flow into upper collector 11. Such increased flow is detected by flowmeter 14, which gives a warning and may activate cleaning means such as external sprays. <IMAGE>

Patent GB-2223915-A (GB)
Title: Record/playback method and apparatus
Inventor: MURRAY BRUCE
IPC: H04S3/02
Filed: 1988-10-14
Abstract: For the record/playback of two information signals, which may represent the respective components for stereo audio or other unrelated information, the two signals are applied via a matrix 10, or directly, to switches 11, 12 such that, in the case of stereo audio, the sum (L+R) and difference (L-R) are derived with the addition of a low frequency ident tone to the difference signal whilst, in the case that the signals are not stereo audio, the signals are derived unaltered. The derived signals are applied to the tape and, on playback, are applied to a further matrix 17, or directly, to further switches 22, 23. When the recorded signals represent stereo audio the ident tone is extracted by filter 19 and tone detector 20 to control further switches 22, 23 to produce the respective L and R signals. In the case that these signals are not stereo audio, a selected one of the information signals is derived from the further switches. <IMAGE>

Title: Microphone actuation control and noise adapting threshold circuits therefor suitable for teleconference systems
Inventor: JULSTROM STEPHEN D
IPC: H04R27/00
Filed: 1989-01-03
Abstract: A noise adapting threshold circuit which generates a voltage level constituting a gating threshold. The threshold circuit comprises amplifier means which receives an input from an associated microphone representing the amplitude level of the microphone input and charges a capacitor the voltage on which is the threshold value, and a capacitor discharge means which discharges the capacitor at a rate substantially equal to the rate of decrease of the microphone amplitude level. The voltage level on the capacitor is preferably modified by a signal representative of loudspeaker sound to avoid gating of microphones in its vicinity. The threshold value is compared with a signal representing the microphone amplitude level so as to develop a control signal for a microphone gating circuit. <IMAGE>

IPC: G07C9/00
Filed: 1989-07-25
Abstract: A personnel location system comprises a plurality of locator units 12 disposed at predetermined locations and each providing a unique signal, an interrogator unit 30 e.g. carried by security personnel including a signal detector 48-52 linked via radio transmitter 46 to a central control unit 54 for transmitting the present location of the interrogator unit 30 in the form of a coded signal when the detector is stimulated by a signal from an individual locator unit 12.

Title: Process for coating phosphor slurry on a cathode ray tube
Inventor: LIM SEONG-HA
IPC: H01J9/22
Filed: 1990-09-20
Abstract: Phosphor slurry 12 from nozzle 11 coats the inner surface of CRT panel 10 which is mounted on a rotating support carrier 20, wherein the inclination of this axis of rotation X-X is varied by swinging the support carrier about a further axis 22.

Title: Improvements in and relating to electrical connectors
Inventor: VAUSE FRANK
IPC: H01R33/96
Filed: 1991-01-31
Abstract: An electrical connector, for example a lampholder comprises an on/off switch mechanism including a pushbar (9, 23). The connector further comprises a locking arrangement including an interlock member (6, 44) which extends to said pushbar (9, 23) and moves into and out of cooperation with an aperture (8, 43) in the pushbar (9, 23).

When no cooperating device is connected the interlock member prevents movement of the pushbar. The pushbar and the interlock member include respective inclined surfaces (59, 61) arranged such that the pushbar will be moved to the off position when a cooperating device is removed from the connector.

Title: Openmouth paint container having rim construction to inhibit fouling of the    container sides on stopping pouring from the container
Inventor: CANE MICHAEL ROGER
IPC: B65D23/06
Filed: 1991-03-22
Abstract: An open mouth paint container (1) has a rim construction for producing a reduced tendency for paint to foul the container outer surface (1a) during the stopping of pouring paint from the container. The container achieves this by means of a rebate 8 formed in its upper outer perimeter (7) which rebate is surmounted by an external edge 10 located inwards of the outer perimeter (7) and by means of a downwardly inwardly sloping surface 17 which leads to an internal edge 18 located behind the rebate. The rebate extends from 5 to 15% of the length of the upper outer perimeter whilst the sloping surface extends from 10 to 20% of the length of the upper inner perimeter. The upper rim-defining portion of the container may be formed by an upper collar 3 spun welded to a lower blind section (Fig. 1) and the rim profile is defined in part by a snap-in insert 11 which may be spaced by gaps 644, 644a (Figs. 6 and 7) inducing capillary action. <IMAGE>

Title: Element-isolating process for a semiconductor device
Inventor: CHO HYEON-JIN
IPC: H01L21/763
Filed: 1991-07-01
Abstract: A process for forming isolation trenches for a semiconductor device includes the stops of: etching a part of a first conductive layer corresponding to the trench region. and thermally oxidizing the remainder of the first conductive layer, to form an oxidized first conductive layer; removing a portion of a second 14 and first 12 insulating layer formed over the substrate, by using the oxidized first conductive layer as a mask, and thereafter etching the exposed substrate, to form a trench; depositing a buffer oxide layer and a second conductive layer of polycrystalline silicon on the inner wall of the trench and above the insulating layers respectively; and filling the interior of trench with only the oxidised second conductive layer 28 or additionally with an insulating material 30 other than a nitride layer. Thus the trench may have a width smaller than that obtained by photo-etching techniques. Further, because the interior of trench may be filled with only oxidised polycrystalline silicon the trench may have a width of 0. 3 mu m - 0. 4 mu m without bird's beak phenomenon. <IMAGE>
