Title: Roller bearing with outer ball race ring - uses close-packed needle-like rollers requiring no cage or inner ring
Inventor: SCHULTE-KUMP FRIEDHELM
IPC: F16C19/46
Filed: 1975-01-07
Abstract: The roller bearing is particularly for use in drawer guides. It comprises an outer ring (2) which forms the ball race with roll members (3) mounted therein right up close next to each other with no cage or inner-ring. These roll members (3) therefore can not fall out, neither radially nor axially owing to the annular disc (4) which are inserted either side in the ball race (2). They can therefore be needle type rollers or cylinder rollers which can be mounted in the outer race without any freedom of movement required in the peripheral direction. The needle or cylinder rollers provides a basically linear contact face which reduces the risk of deformation.

Title: Continuous production of relatively thin chipboard - using high frequency heater to increase density and tensile strength
Inventor: GRETEN BERNDT DIPL ING
IPC: B27N3/26
Filed: 1975-07-08
Abstract: Relatively thin, continuously running chipboard is manufactured in a plant having an endless steel belt running over a pressure bowl, with guide, driving and tensioning rollers. A spreading arrangement for the chips, fibres, etc. impregnated with a bonding agent, is positioned above a horizontal section of the belt, load being applied by holding-up rollers as it runs part way round the circumference of the bowl, adjusted so as to leave a gap between bowl and belt slightly narrower than the desired thickness of the finished board. The initial density value and the physical characteristics such as tensile strength of the product, are increased by means of a high frequency heater located in front of the nip between belt and pressing bowl. The introduction of H. F. heating increases the density of the board to from 850 to 900 kg/m3, without increasing the load and the consequent wear and tear on the belt and the bowl. The thickness of the board may thus be reduced from 6mm to 4mm.
