Patent DE-2709166-A1 (DE)
Title: Portable gas generator - with solid and liquid reagents in two spherical containers accessible through burst discs
Inventor: RAMAKER HERMANN
IPC: B01J7/02
Filed: 1977-03-03
Abstract: A portable gas generator consists of two spherical containers, one with a solid and the other with a liquid reagent, which can be coupled together to initiate a reaction. Each container has a closed tubular connector which pierces during the coupling operation a burst disc in the other container top and is itself opened thereby. The container with the solid reagent has a connection for a consumer. This gas generator is much more portable and handy than the use of gas compressors. Pressurized gas bottles are also much too heavy for many applications. The gas production can be easily interrupted by inversion of the containers.

Title: Monitoring system for cable TV networks - has several amplifiers each with transmitter generating individual frequency derived from common reference frequency
Inventor: THOENER GERHARD DIPL ING
IPC: H04B17/40
Filed: 1977-03-29
Abstract: The network (1) has devices for distance monitoring of the operating state of amplifiers provided in the network. It uses characteristic frequency monitoring transmitters allocated to individual amplifiers. Output signals of the transmitters are applied to one or several monitoring stations. Characteristic frequencies allocated to individual monitoring transmitters are derived from a common reference frequency transmitted over the network, and the individual frequencies are synthesised in each monitoring transmitter. There is a receiver (E) passing a signal to a frequency divider (T1). The output (ft1) is passed to a phase regulating network (PL) which receives a second signal (Ft2). The output of the network (PL) passes to a (VCO) which has a feedback to the frequency divider (T2) supplying the second signal to the network (P2). The VCO is connected to a low-pass filter (TP).

Title: Electronic reward points recording system - uses minute clock and reed switch with digital counter giving audio and visual indications of correct responses during behaviour therapy
Inventor: HIRSEMANN HANS
IPC: A61B5/16
Filed: 1977-05-04
Abstract: The electronic signal evaluating and adding arrangement gives immediate audio and visual indications of correst responses during behaviour therapeutic sessions in schools and institutes. It gives direct encouragement without breaking the class or consulting room proceedings. Children with special behavioural problems are often unable to postpone palpable rewards until eg the end of the period. An electronically controlled stepping motor switches a reed contact of a minute clock by means of a small magnet held on its hand. This contact releases a counting pulse for indicating the next higher figure. A relationship is established between the clock and a digital counter to show points awarded during a given period.

Title: Plastics foil sheeting green house or frame tent - has larger door than door frame providing seal on outside
Inventor: BECKMANN GERHARD
IPC: A01G9/14
Filed: 1977-07-29
Abstract: The door wing frame (6) is larger than the actual door frame so that when the door (4) is closed the wing frame (6) runs on the outside of the door frame so that the sheeting (9) which forms the door adjoins the door frame and/or the greenhouse sheeting (3) adjoins the door wing frame. Thus when the door is closed two seals are formed i.e. one between the larger door wing frame and the green-house sheeting and a second between the smaller door frame and the door sheeting. Even if one seal does not act 100% the interaction of the two seals provides a labyrinth seal which ensures a perfect sealing effect. The door frame and door wing frame are pref. made of galvanised steel tubing wherein the tube can be fitted with a longitudinally slotted plastics tube into which the edges of the sheeting are clamped.

Title: Printed matter opening machine - exerts hindering force perpendicular to travel direction causing top half to arch upwards
Inventor: SOEHLKE AXEL
IPC: B65H5/30
Filed: 1977-11-02
Abstract: The machine opens up printed matter with a rear fold, partic. magazines etc. for the insertion of samples. A conveyor (1) delivers the magazines etc. (DP) with their rear folds running in the travel direction, and a hindering force at right angles to the travel direction and in the plane of the magazines is applied to them, while they are simultaneously prevented from deflecting. This causes them to open up at the fold, and the top half (OH) to belly upwards at right angles to the travel direction, so that a divider (16) can engage in the opening formed. This swings the top half upwards through a predetermined angle in relation to the bottom one and holds it there for a set length of the conveyor track.
