Title: Cable connector system for wiring logic modules - is capable of passing more channels than required by one logic element
Inventor: BOENING WERNER
IPC: H01R25/00
Filed: 1976-10-29
Abstract: In the proposed connector the joint between the connecting cables is made external to the logic modules and separate connector pins on the plug complete the circuit to the logic element. The cables are typically of the flat type (S1, S2). One of the cables (S1) is taken to the plug section (KT) of the connector whilst the other (S2) comes from the socket half (GS). Interconnecting pins (SV) join the two within the connector housing. The top face (AW) of the plug section (KT) has additional pins (ST) which make the required circuits to the logic module in question. The construction enables better use of the number of cores in one flat cable thus more element can be coupled up in one run.

Title: Automatic separation of distillate fractions of brandy - using alcohol meter and measuring chart to actuate photoelectric switches
Inventor: VOLLERT JUN EMMERAN
IPC: B01D3/42
Filed: 1977-02-11
Abstract: An appts. for sepg. the first runnings, middle runnings and last runnings in the distn. of brandy or other spirits, esp. in concn. plants, operates by measuring the alcohol content and using it to control the distribution device. Pref. a conventional alcohol meter is used for the measurement; this contains a measuring chart (strip chart), which is partly transparent and partly opaque and acts as the obstructing slide for >=1 photoelectric devices, which actuate valves at e.g. 60%. 50%, and 5% alcohol levels. By making the valve switching operations automatic, errors resulting from failure to observe the correct time for sepg. the various fractions in the distilling process are eliminated.

Title: Expanding dowel for hollow walls - has expanding flaps on cylindrical body with rotation preventing guide surfaces
Inventor: HACHTEL ROBERT
IPC: F16B13/04
Filed: 1977-02-18
Abstract: The dowel for hollow walls aims at ensuring that no rotation of the dowel inside the hole takes place. The dowel has a guide part (10) with lateral slots (19, 20). On the external surface of the guide part the locking element with expanding flaps is slidably fitted. The guide part has a collar (14) at the wall cavity end. When the dowel is pushed into the hole the flaps fold into the lateral slots (19, 20). When the tips of the flaps clear the inner surface of the cavity, they expand and during the following rotation of the screw the body of the guide elements slides along the part with the lateral slots until the flaps come to rest against the inner surface of the cavity.

Title: Soilless hydroculture substrate mfr. - from pelletised organic and vegetable waste material with admixtures
Inventor: GRUBER RICHARD DR
IPC: A23K40/10
Filed: 1977-05-13
Abstract: In the prepn. of substrates for a soil-less hydroculture in plates or mats, difficulties in obtaining a suitable substrate at low cost have led to the use of refuse from fruit farms or organic waste from the municipal refuse collection as raw material. There are enriched by a nutrient soln., trace elements and vitamins and finally pelletised with the application of heat and pressure. This simplifies the prodn. of a suitable substrate and helps reduce the pollution of the environment by disposing of waste material.

Title: Shrink fit system for metal casing - has metal sheet butt welded at ends shrunk by blind weld seams
Inventor: CYRON THEO
IPC: B23P11/02

Title: Sheet metal perforating press with hydraulically driven tool - has increased pressure acting against ram before or at moment of tool to workpiece impact
Inventor: CHRUBASIK PAUL
IPC: B21D28/20

Title: Ic engine exhaust gas afterburning chamber - has additional air intake guide for second stage with heat exchange surface
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1977-11-28
Abstract: The counter-scavenging combustion chamber is for the after-burning of i/c engine exhaust gases. It has a first stage (1) with a gas feed pipe and an additional air input. In a second stage (6), in which the ignition element passes through the counter walling (5) and has its seat (15), the opposite surface acts as a guide for the additional air quantity entering the reversing area of the after-burner chamber. This additional air feed guide system evolves into a part flow hole or channel field (28), whilst its other part evolves into a lengthways guide chamber (31) which encompasses a combustion chamber extension (3), and forms with it a heat exchange surface (17).
