Title: Radial and axial play elimination arrangement for CD player - allows magnetic force to act between disc and circle segment on fixed retainer that guides spindle
Inventor: ELSAESSER AXEL
IPC: G11B19/20
Filed: 1990-01-18
Abstract: The arrangement eliminates radial and axial play in a spindle (A) on which a disc (S, RM) sits and that is guided by a fixed retainer (F,P). The materials from which the disc and the retainer are made allow a magnetic tone to act between these two components. A segment (K) of a circle is arranged on the retainer next to the disc. A magnetic tone acts between the segment and the disc. The spindle's bearing (M) is fixed to a flange (F) which is in turn fixed to a casing (G). The flange has a ring magnet (RM) through which the spindle passes. The said segment is located next to the disc on the flange. The flange and the segment are metal.

Title: Bandsaw blade producing narrow cut - has waisted section behind teeth which are narrower than blade thickness
Inventor: BERGVALL JEAN GUNNAR
IPC: B23D61/12
Filed: 1990-04-12
Abstract: A typical bandsaw blade, having a thickness say of 1.47mm has the blade edge thickened to give a tooth breadth of at the cutting edge (2a) of 3.07mm. This ensures ensuring that the trailing part of the blade will not jam in the cut. The proposed blade, has a reduced section (3c) immediately behind the teeth (4), and the tooth breadth at the cutting edge (4c) is 1.1mm. ie less than that of the trailing part of the blade. In spite of this investigation has shown that jamming of the blade in the cut does not occur. A riving knife of thickness equal to that of the trailing part of the saw blade and with holes for coolant flow is used. USE/ADVANTAGE - Bandsaw blade giving reduced material wastage.

Patent DE-4028188-A1 (DE)
Inventor: BERGER HORST DIPL ING
IPC: G08B17/11
Filed: 1990-09-05
Abstract: The scattered-light system (7-9) and the ionisation system (12, 13) are arranged in the same plane on a common base plate (1). The measurement volumes of the scattered-light system and of the ionisation system are located on both sides of the central axis of the chamber.

IPC: G02F1/1343
Filed: 1990-11-07
Abstract: Liquid crystal displays (LCD) consist of a large area, pref. glass, panel (1,2,3) and a smaller covering panel (5). The electrode contacts (4,8) on the larger panel are made from a thin film of SnO2, In2O3 and PdO, applied by sputtering, in which the pattern of electrodes is formed by a photolithographic process. The electrodes (4) which will be in contact with the liquid crystal are then covered with a thin film of SiO2.P2O5, SiO2 or SiO2.TiO2.

Then an orientation layer for the liquid crystal is deposited on the insulation layer covering the internal electrode array and the small covering panel (5), carrying its electrode array, placed on top. The cell is then completed by inserting the liquid crystal (10), sealing the cavity (7) and adding external components (9) to the larger panel. The conductive oxide layer is pref. deposited by sputtering the metals and oxidising the layer by an anneal, or by reactive sputtering using one or 2 targets. In the latter case one of the targets is PdO or PdO2. The additional metal layer applied to the external electrode array (8) is pref. Ni, Cu, Au, etc., and may be applied directly or after reducing PdO to Pd in the external array. USE/ADVANTAGE - Provides electrode arrays with different properties for different tasks. The external electrodes allow direct bonding of TAB packages to the glass panel. The process is suitable for mass production.

Title: Bobbin-winder - has ratchet lock for slide of contact roller and yarn guide to move in only one direction during winding
Inventor: WESTRICH HERMANN
IPC: B65H54/52
Filed: 1991-01-15
Abstract: The bobbin winder, with a slide for the contact roller and reciprocating guide which bears down by the force of gravity, has a lock system to fix its position over the whole length of slide movement as the wound bobbin increases in size. The lock system allows the slide to move  only in one direction, during bobbin winding, away from the bobbin spindle as the wound bobbin dia increases. The lock system is pref a ratchet on the slide and a fixed rack attached to the machine frame. During winding, the ratchet is pressed against the rack to ensure that the teeth are engaged positively. When the slide is to be lowered, the ratchet is displaced from the teeth of the rack to allow slide movement against its normal direction. The winder has two bobbin spindles, mounted on a rotating turret to bring each spindle alternately into the operating position. When in the operating position, the spindle is on or behind the common axial plane of the contact roller and the bobbin turret. ADVANTAGE - In the event of a stoppage the residual energy in the slide mechanism is very low and, on a bobbin change, the time and energy required to position the slide is at a low level.
