Title: Difficulty flammable wood product, esp. chipboard - made avoiding viscosity problems
Inventor: KIPPENBERGER WUNIBALD
IPC: C08L97/02
Filed: 1973-07-20
Abstract: Difficulty flammable wood prods. are made by treating a mixt. of wood chips and flame-retardant with a part of the binder, drying the composite, adding the rest of the binder and curing. As most flame-resisting additives are acidic in nature, storability. viscosity and/or concn. problems arising when the normal prodn. processes are followed are obviated by using the present sequence. The optimum degree of re-wetting of the dried chips prior to moulding can be effected. Conventional (aminoplast) binders may be used. These may contain 10-15 wt% of the flame-resisting additive (e.g. H3BO3, (NH4)3PO4, NH4BR, urea or melamine and, esp. mixts. thereof with, e.g. kaolin). Impregnation of the chips with the dil. resin compsn. is continued till the desired uptake of additive has been reached (e.g. 10%, based on dry chips wt.) after which the chips are dried to, e.g. 2-5% before addn., when reqd. of the remainder of the binder.

Title: Anti-theft device for skis - skis carry spring catch with releaseable lock
Inventor: NOACK GUENTER
IPC: A63C11/00
Filed: 1974-01-03
Abstract: The top of one ski, carries a spring catch with lock, in front of the binding. The second ski carries the corresponding insertion pin unit, so that with connected catch and unit, the two skis form a large unwieldy cross, enclosing the angle. During locking, the movable latch in the lock, which projects through an aperture into the bore, is pushed by the pin against a spring, and engages into a groove, when a plate contacts the housing. A second pin in a bore fixes the cross shape. To release the lock, the locking pin is turned by a key, to move the latch of the groove, until the locking pin engages in the open position. The skis are separated, and the locking pin is returned, so that the key can be retracted.

Title: Cam with variable lobe - has common screw connection for angular and radial adjustment of lobe
Inventor: KATZ WOLFGANG
IPC: F16H53/04
Filed: 1974-01-11
Abstract: The cam comprises a carrier to be secured to a shaft by keys. The carrier supports the lobe by means of screws which pass through arcuate slots of the carrier and radial slots of the lobe. Thereby, when the screws are slackened, the lobe can be moved angularly or radially with respct to the axis of the shaft. There may, for example, be fine arcuate slots to allow for arcuate displacement through, say, 50 deg.. The remaing 22 deg. can be accommodated by changing the position of the carrier on the keys. The proposal provides an infinitely variable cam within the constraints mentioned.
Patent DE-2408216-A1 (DE)
Title: Brake self-acting lining wear adjuster - has opposed pistons unaffected by variation in clearance due to thermal expansion
Inventor: REINARTZ HANS-DIETER
IPC: F16D65/56
Filed: 1974-02-21
Abstract: The nut on the stud of the piston is held in contact with the conical bore of the adjuster by spring. When the pistons move apart slowly due to thermal expansion the nut rotates due to the rotation imparted to the adjuster by the pin sliding in the oblique slot in the extension of the piston. As the pistons resume their initial position the nut rotates back to its original position. When the brake is suddenly applied the friction ring restrains the adjuster and the nut is not rotated. When the brake is released the adjuster being now in contact with the nut rotates it to a new position.

Title: Communication system with sine or trapezoidal waveform - wave sent through conductor loop to store and indicate four states
Inventor: DAMMANN RICHARD
IPC: G08B25/14
Filed: 1974-03-29
Abstract: The central unit consists of a 47 Hz frequency generator followed by a trapezoidal forming circuit. The waveform is fed to a conductor loop via a monitoring unit, which detects whether positive or negative half cycle current are present or missing and sets 4 store units when gated by narrow pulses derived by differentiation of the original square wave. The store units drive lamps to indicate the four possible states "quiescent", "indication", "open-circuit", and "short-circuit". The remote station has two bistable units, relays or electronic circuits, two LED's, one reset monostable, three rectifiers and three keys. In the quiescent state the current path is such that is passes through the two bistable relays in one direction only via a rectifier. If the indication key is depressed in the current flows through a rectifier of the opposite polarity and the two relays change over.
