Title: Extension table guide arrangement - ensures that extension board is moved horizontally before raising into operative position using longitudinal and transverse beams
Inventor: BAERISWYL-HEIERLING ARMIN
IPC: A47B1/05
Filed: 1977-01-29
Abstract: The main board of the extension table is horizontally shifted on the table frame formed by longitudinal beams (2) and transverse beams (3). The beams feature guide grooves for lugs (6/6) of the main table board (8). The extension board (11) is normally beneath the main board (8) which extends between the table legs (1), and board n11) is moved out with its lugs (9/10) controlled by the horizontal grooves. Maximum length of the table is achieved when the main board (8) is shifted to the left and the extension board (11) is moved to the right, lugs (9) of the latter reaching the inclined guide grooves. This ensures a horizontal end position for board (11).

Title: Quick adjustment spring loaded dividers - have two brackets of double nut spreader lever on common tilting axis
Inventor: KNAPPICH JOSEF
IPC: B43L9/22
Filed: 1977-02-04
Abstract: The quick-adjusting dividers have a spindle in a split nut rotating inside each leg, the nut halves being spring-loaded against the spindle and spread clear of it by an external double lever. There is an opening in each leg, through which a bearing bracket of the lever passes. The two brackets (50) of the double lever (38) are supported on a common tilting axis (52), and they can be arranged to fit one inside the other. The complementary bearing parts of the two brackets can be arranged to snap into engagement so that they cannot come apart. The two bearing parts can have one or more bearing trunnions and openings, while one or both brackets is elastic. Thus on insertion from opposite sides into the leg opening (40) the trunnion snaps into engagement with the bearing opening.

Title: Single piece table tennis bat - with base thickening from blade tip to grip end and axis of grip which passes to one side of blade centre (NL 6.9.77)
Inventor: PERKINS ROBERT
IPC: A63B59/04
Filed: 1977-03-04
Abstract: This table-tennis bat has an almost elliptical blade (10) from which extends a grip (11). The grip axis (12) passes to one side of the centre point (13) of one blade (10). The end (14) of one grip (11) is thicker than its blade end (15) and has its curved sides rounded to provide a more comfortable grip. The thickening of the grip moves the point of balance (25) of the bat closer to the grip to provide a better 'feel' in use. This effect is heightened by continuing the thinning down of the base material from the grip to the tip of the blade. This can also be achieved in a bat of equal thickness by adding weights into the grip.

Title: Hollow filament dialyser and hank winder for filaments - allowing number of filament bundles to be wound simultaneously
Inventor: FITZGERALD JAMES A
IPC: B01D63/02
Filed: 1978-04-28
Abstract: A semi-permeable, endless capillary yarn is prepd. for use in a hollow filament dialyser in which a gp. of filaments open at their ends and equal in length, is assembled, in a series of steps. In a winding machine, >=1 package of the hollow filament yarn, is positioned on a support spindle and wound on to a large size swift with a number of yarn supports spaced out uniformly, so that a series of straight sections of yarn layers are formed, each having a number of spirals set up by the yarn guiding mechanism. Each section of the hank is enclosed by a tubular clamp, hinged so that it can be opened and slipped over the windings in a particular section, and the yarn is cut through close to the ends of the clamp, to give bundles of fibres open at their ends. The winding is effected in such a way that compression of the spirals of the filaments is prevented. Each spiral crosses the adjacent spiral below it; the swift rotating at a speed higher than the speed of oscillation of the filament along a line parallel to the axis of the swift. This makes it possible to produce the hollow fibre dialysers without the need to incorporate the winder detail in the dialyser housing, at a greatly increased speed.
