Title: Method for producing comparison variables for the behaviour of different tennis rackets
IPC: G01P3/64
Filed: 1988-12-16
Abstract: In order to produce comparison variables for the behaviour of different tennis rackets from the point of view of the individual mechanical loading of the player, the player, whose playing wrist is fitted with an electrical accelerometer, uses each racket to play a number of balls, fed without rotation from a ball throwing machine, against a wall which is provided with an impact sensor. With each stroke, the maximum acceleration occurring on ball contact is measured quantitatively and the mean speed of departure of the ball is determined from the time difference between the ball contact and impact on the wall. The prescribed speed of arrival of the ball is then used to calculate the change in speed of the tennis ball effected by the stroke, and from the maximum acceleration of the wrist and the change in speed the quotient is determined separately for each racket as a measure of the relative level of the arm loading specific to the racket.

Title: Manual adjusting mechanism for a 3-part lounger (couch) frame
Inventor: SCHLIPF ANDREAS
IPC: A47C20/04
Filed: 1989-02-10
Abstract: Known lounger frames with adjusting facility had the disadvantage that adjustment entailed certain difficulties (see description), or if conveniently adjustable they were correspondingly expensive. The new manual adjusting mechanism is to enable adjustment into an ergonomically favourable posture in a convenient, safe and inexpensive manner. For this purpose, use is made of a locking means (in accordance with the first main claim) at the pivot point of the back part, which locking means enables the combination of back-, seat- and foot-part adjustment, and is conveniently adjustable with the aid of the Bowden cable by displacement of body weight.

Title: Freeing air streams and gas streams of solvents and other volatile substances by scrubbing and distillation
Inventor: STARK HELMUT
IPC: B01D53/00
Filed: 1989-02-17
Abstract: According to the invention, air and gas streams which contain solvents and/or other volatile constituents are freed of these by introduction into a liquid in which these substances are readily soluable. They are absorbed there and the purified exhaust air escapes via an exhaust air pipe. If necessary, a plurality of scrubbing units can be connected in series. The liquid is situated in a closed vessel and air is fed into water by means of a fan of a fine distribution device. The vessel is provided with a liquid level indicator and controller device. To free the scrubbing liquid from waste it is fed to a distillation unit where the dissolved substances can be separated off. Fractional distillation can be carried out in the case of mixtures of substances. Vacuum distillation can also be used. The advantage of the unit is the recovery of the individual substances. The unit is suitable for freeing paint spray booth exhaust air from waste.
