Patent DE-2832905-A1 (DE)
Title: Simplified expanding reed mechanism with separable carriers - related to single fixed point located on central coupling
Inventor: WIEDENFELD HELMUT
IPC: D02H13/16
Filed: 1978-07-27
Abstract: Separable, two-part expanding reed comprises multiple jointd reed elements mounted in two movable carriers having longitudinal screws to adjust the angle between reed elements which can be coupled and uncoupled by means of a linkage which joins together the first reed elements of each part. Reed expansion takes place w.r.t. a fixed linkage point in the centre of the coupled reed which lies beneath the first element of one part. After separation of the two parts, a substitute fixed point for the second part of the reed is provided by the insertion into the end of the second carrier of a connector plate carrying a shackle which is attached to the free end of the first reed element of the second part. Coupling and uncoupling of the two parts is rapid and simple, and longitudinal freedom of motion of the parts, whether coupled or uncoupled, is unrestricted. Expansion of the reed from the centre outwards eliminates the need for re-positioning of the carriers whenever the width is altered.

Title: Mouldings made of glass, ceramics, plastics etc. - are made in double-acting press where upper punch is also used to eject moulding from mould
Inventor: LANG GEB LAHMER MARGARETHA
IPC: C03B11/08
Filed: 1978-08-10
Abstract: A molten mass is fed into a mould which has an open top and an open base, and is mounted in a press. The mould base is initially closed by a punch driven vertically by a work cylinder. An upper punch is driven into the top end of the mould by another work cylinder to press the molten mass. The punch is then retracted so the upper punch can continue its downwards travel to push the moulding onto a transporter mounted on a swivel and removing the moulding out of the press axis. In the pref. press, both the bottom surface of the upper punch, and the top surface of the lower punch, possess profiles producing corresp. shapes on the top and bottom surfaces of the moulded part. Both the moulding time and the cost of the moulded parts are reduced.

Title: Two=stage bottle washing machine - uses vaporisation or hyperfiltration in first stage for re-cycling liq. to sprays in both stages
Inventor: KRUEGER ROLAND DR
IPC: B08B9/20
Filed: 1980-07-15
Abstract: The bottle washing machine with two main washing zones uses a vaporisation process in the first zone. There the condensed steam from the washing liquid is mixed with fresh water for water sprays in an upper region. The bottles first pass through a washing vessel in this zone, and this liquid is fed through a line to the vaporising stage. In the second zone, the liquid from the sprays is passed through a filter to remove solid material, followed by a neutralising stage where the waste material is extracted as a sludge. Alternatively the solid material can be separated by filtration or by centrifugal separation. Instead of the vaporisation process, hyperfiltration can be used, and the recycled water is applied only to the last spray sections in the first zone.
