Title: Biological sewage treatment - combines activated sludge with bio:adsorbent fluidised bed
Inventor: KOPPERNOCK FRED DR
IPC: C02F3/12
Filed: 1978-03-23
Abstract: An activation process for use in the biological sewage treatment uses in addition to the activated sludge process a bioadsorbent in a fluidised bed inside the aeration tank. This reduces the concentration of substances of poor digestibility and eliminates the toxic effect on fish. The sludge properties are improved and/or the sewage can be bleached. Specifically a first pipe is used for the sewage inflow and the sludge recycling. A second leads to the reclarification basin. The bioadsorbent (e.g. granulated activated carbon) in the fluidised bed is kept sepd. by two screen decks.

On one side this acts with the programming circuit and the position of the door in the housing, and on the other side it controls the axial movement of a disc on the rotary axis of the programme switch unit when the door or lid is opened. The system gives a high degree of safety in operating the washing machine, irrespective of the type of programme switch and its mounting in the equipment.
Patent DE-2914809-A1 (DE)
Title: Mounting system for rotating machine - fits stator core to casing and reduces noise by using elastic compression bars and spring parts
Inventor: CHUTORECKIJ GARRI MICHAJLOVITS
IPC: H02K1/18
Filed: 1979-04-11
Abstract: The mounting system has elastic compression bars (3) and spring parts (6). The spring parts are pressed against the parts (5) fixed to the core until elastic deformation occurs. This pressing occurs before the compression bars are fixed to the casing (2) and is accomplished using pressure elements which are removed after the core (1) segments have been fixed to the elastic compression bars. The advantage lies in secure fixing and in reducing the acoustic noise produced whilst the machine is running. The elastic compression bars (12) use screwed threads fitted with nuts to compress the stack of core segments through end plates (13).

Title: Terminal connection for tubular rod heating element - using two-armed spring clip to join contact element to terminal bolt
Inventor: SIMONIS KARL ING GRAD
IPC: H05B3/48
Filed: 1979-04-26
Abstract: The terminal connection for a heating element (1) having a heating wire embedded in an insulating mass, uses a two-pronged spring clip (3) to secure a contact element (7) to a terminal bolt (2) extending from the end of the heating element (1). The current supply lead is subsequently attached to this contact element (7). The arms of the spring clip (3) have aligned holes, through which the terminal bolt (2) and the contact element (7) are both threaded, before moving the ends of the arms away from one another. Thus the terminal bolt (2) and contact element (7) are clamped together.
Patent DE-2919300-A1 (DE)
Title: Circuit board component solderless contacting - uses eyelets formed at component lead ends for bolted joint, using compression
Inventor: BLEUEL WALTER ING GRAD
IPC: H01R12/55
Filed: 1979-05-14
Abstract: The connecting method is for use with electronic components having lead tails, e.g. resistors or small capacitors. In order to make a connection without soldering an eyelet is formed at each lead (1, 2) end of the component (14). An insulation separator (4), typically in the form of a washer, is then placed between the eyelets. A bolt is then passed through the eyelets and the insulation washer. With the bolt making contact with one lead end, the other one is pressed against a conductor on the printed circuit board (19) when the bolt is passed through the board and tightened. The bolt forms the other terminal, and a solder tag (21) can be placed under the nut before tightening. It can be used for attaching an interconnector.

Elaborate foundation work is eliminated, and elements can be filled with earth, and support vegetation.
Patent DE-3009770-A1 (DE)
Title: Pressure plate for wooden workpieces - has rows of small pressure chambers to spread load and reduce leakage
IPC: B27D3/04
Filed: 1980-03-14
Abstract: A wooden workpiece is moved with a stepwise motion whilst a film is bonded to its surface. The workpiece is subjected to a pressure exerted on a moving belt (10) lying above the workpiece. The belt passes beneath a pressure plate (11) which has rows of small squat cylinders (12) attached to its undersurface. Each cylinder houses a piston (14) which is pressed onto the belt by a coil spring. The piston has a skirt (24) which encloses a pressure chamber (22) which communicates with the pressure chamber (20) inside the cylinder. Both pressure chambers receive compressed air through a duct (32) in the pressure plate. By using a number of small pressure chambers the pressure is spread evenly over the workpiece but with less leakage than with a single large pressure chamber.
