Title: Grinding or polishing device
Inventor: REILING REINHOLD
IPC: B24D3/00
Filed: 1988-12-14
Abstract: A grinding or polishing device with a long working life comprises fibre portions (2) coated with a bonding agent and carrying abrasive grains (3), the fibre portions (2) with the abrasive grains (3) being attached to a semi-rigid profiled synthetic carrier (1) by means of an adhesive compound, especially by a mixed adhesive or by contact adhesive.

Title: Method and apparatus for controlling dictation on or transcription from recording units in a dictation system
Inventor: JACHMANN EMIL F
IPC: G11B27/34
Filed: 1989-01-16
Abstract: A dictation system is disclosed having two or more recording units (12, 12', 14, 14'), each selectively operable as a dictation unit or a transcription unit, and including a selector (42, 42') for selecting a respective unit for recording or transcription. A unit selected for recording dictation is enabled if a record medium therein is ready, or initialized, for recording; otherwise the unit is enabled for transcription. While one unit operates to record dictation, the other may operate simultaneously to transcribe previously recorded dictation. In a system having at least three recording units (12, 12', 14, 14'), at least two are identified with respective, particular identities and the third is designated a spare recording unit. After a predetermined amount of dication has been recorded on any one of the identified recording units, a further dictation destined for that identified unit is recorded on the spare unit, and the identity of the spare unit is changed over to be equal to the identity of the recording unit for which dictation has been intended. In such a system, the original identities of the at least two recording units are established in the order in which those units are initialized, or made ready, for dictation. <IMAGE>

Title: Eyelash curling device
Inventor: CHOU KUEI-CHUN
IPC: A45D2/48
Filed: 1989-05-15

Title: Teletext decoder with reduced page-access time
Inventor: BOON ANDREW LYNDEN
IPC: H04N7/025
Filed: 1989-05-25
Abstract: The decoder includes a video input processor VIP 10 that derives teletext data from the vertical blanking intervals (VBIs) of a video input signal. A computer controlled teletext circuit CCT 12 responds to a select page command from microcomputer 16 to acquire data corresponding to a selected page, and to decode the acquired data. The CCT 12 can adopt either a VBI mode, locking for teletext data only in VBIs of a video signal, or a full-field mode. A memory controller 42 receives data from the VIP 10 and continuously extracts teletext data therefrom and stores the extracted data on a FIFO basis in memory 40. The memory controller 42 inhibits the storage of at least one predetermined teletext extension packet, e.g. packet 31 and/or 30. Upon a page request, the microcomputer 16 puts the CCT 12 into the full-field mode and supplies the memory controller 42 a scan request SR that causes it to supply the CCT 12 with the data stored in memory 40 in place of the data from VIP 10. Operating in full-field mode reduces page-access time. Memory 40 may contain one or more teletext magazines. <IMAGE>

Title: Valve
Inventor: KOLENC TERRENCE JAMES
IPC: F16K1/36
Filed: 1989-11-17
Abstract: A valve closure member comprises a body 78 having a cylindrical portion on which is received a rigid metal ring 152 backed by a PTFE ring 158 and surrounded by a resilient plastics ring 160, which in turn is held captive by an axially slidable sleeve 166.

Title: Fluid friction coupling with closing slide
Inventor: TAUREG HERBERT
IPC: F16D35/00
Filed: 1990-03-12
Abstract: A fluid friction coupling (1) comprises a housing (2) and a hub (4) rotatabiy received within the housing, the interior (11) of the housing being divided into a main chamber (22) and a receiving chamber (23). Only the main chamber (22) is occupied by inner plates (8) and outer plates (6) of the coupling. The two chambers (22, 23) are separated by separating plates (18, 19). The plates (18, 19) comprise closable apertures (24) each of which is associated with a slide which opens the respective aperture (24), thereby providing a passage between the two chambers (22, 23), when a certain rotational speed is exceeded. As a result, the possibility of a transfer of the coupling (1) into the hump mode is reduce at high rotational speeds. The coupling may be used in a torque-splitter (Fig 4) with two independently rotatable hubs, and either coupling may be used in a four-wheel drive vehicle layout (Figs 5 and 6).

Title: Quick-acting pipe coupling with cut-off valve
Inventor: EKMAN THURE
IPC: F16L29/00
Filed: 1990-04-24
Abstract: Coupling comprising male and female parts (1, 2). The female part comprises an inner sleeve (4) which, in the non-actuated position of the female part, assumes a closed position. When the male part is inserted, the inner sleeve is acted upon counter to the action of a spring function towards an open position, in which the passage through the coupling is open. At section (18) the male part is provided with an inner surface (18a) which, upon insertion of the male part into the female part, surrounds a corresponding outer surface (4d) on the inner sleeve. Sealing members (18b, 18c and 21) prevent media leakage during the coupling movement. The inner sleeve is designed to execute, upon exposure to a media pressure, for example a media pressure in the male part, a longitudinal displacement towards its fully open position independently of the male part. The sealing members effect their sealing function during the whole of the independent longitudinal displacement.
