Patent DE-2338379-A1 (DE)
Title: Precast slab for floor or wall heating system - has insulating passage below heating passage
Inventor: PLEIN HANS RUDOLF DIPL KFM
IPC: F24D3/14
Filed: 1973-07-28
Abstract: The slab is cast in concrete or similar material and has a circular passage into which can be inserted hot water heating pipes or electric heating cables. There is a semicircular annular passage, below this, which can contain air or be filled with other insulating material. This prevents heat passing down from the slab and directs the output to the upper surface. Further air or insulation filled passages to the sides of the heating passage provide insulation in the laterial direction.

Title: Ultra high speed travel vacuum tunnel tube - with terminal pressure equalisation chambers for train entry and exit
Inventor: WEISS WOLFRAM
IPC: B61B13/08
Filed: 1973-07-31
Abstract: The device is for a tunnel of any required length, such as under the width of the English Channel, in vacuum tube form, for vehicles of unlimited speed, esp. linear-motor-driven magnetic hover trains. Tunnels could be extended to a traffic network, with pressure-equalisation chambers maintaining a constant vacuum, where a number of trains could be accommodated, passing through in rapid succession. Chambers would each have two air-tight doors, and a vacuum-pump installation immediately adjacent to each end, the trains being admitted as soon as the inner door is closed.

The lock actuating handle can be fastened to any required height on the rack. This locking rod is hooked at the top and its lower end is trapped under the locking bracket pin.
Patent DE-2341581-A1 (DE)
Title: Tool movement control e.g. in injection moulding machines - using pneumatically operated calibrated nozzles or metering orifices
Inventor: GUMBERT HANS
IPC: B29C45/84
Filed: 1973-08-17
Abstract: A pneumatically operated calibrated nozzle gives a signal as one part of a tool approaches another party by a predetermined distance, whereby the tool control mechanism may be adjusted to a further approach of the parts. The claimed arrangement is said to be insensitive to vibration and can sense e.g. any residual material left over in the tool from previous moulding cycles which may damage the machine if moulding continues unchecked. A further calibrated nozzle may be provided which gives a signal when the tool parts are not sufficiently close to each other, the machine being stopped.

Title: Perforating plastic or paper foil - uses pointed electrodes mounted on a roller while the foil is mounted on a flat electrode
Inventor: BROKMANN MANFRED
IPC: B26F1/28
Filed: 1973-12-17
Abstract: The arrangement consists of a roller round the circumference of which a number of pointed electrodes are mounted in a regular pattern, e.g. in a screw line. The roller forms one electrode, which electrically interconnects the pointed electrodes mounted on it. The roller is connected to one pole of a voltage source. The roller rotates above the material which is to be perforated. The other side of this material lies on a flat strip electrode which is connected to the other pole of the voltage source. When the pointed electrode faces the foil, a discharge will take place and perforate the material. The arrangement is used for perforating non-conductive foils, e.g. to make artificial leather porous.
Patent DE-2364339-A1 (DE)
Title: Height levelling suspension strut - operated in conjunction with regulated axle and with variable floating piston
Inventor: BECKER BURCKHARD
IPC: B60G17/033
Filed: 1973-12-22
Abstract: A simple, economic form of height levelling suspension for the front wheels of the vehicle is obtained by having the rear axle controlled by height sensors as normal, and with special suspension elements on the front wheels. These have floating pistons whose position is set w.r.t. the control pressure in the rear axle units, and have the effect of regulating the front wheel suspension in relation to that of the rear wheels. Two more inputs to the front suspension units have high and low pressure connections so that the units are self regulating about the set point w.r.t. movements on the front suspension.

Title: Goods transporter mechanism from dispenser - has rotary component with lengthwise compartments containing unloading thrusters
Inventor: SOLLERUD SOEREN ELOF MAURITZ
IPC: B65B1/36
Filed: 1974-02-18
Abstract: The mechanism is particularly for the transport of goods in lump or granular form, from a number of dispensing units to a single receiving unit, e.g. a bag-filling machine. A rotary component accepts material into compartments in one position from the dispensing units, and in another discharges them to the receiving unit, the compartments being kept shut in between. Each compartment extends for the entire length of the component, and is brought once under all of the dispensing units, receiving a charge from each. Each compartment has a thruster delivering the material in it to a position in the compartment which is above the receiving unit after the component has been rotated for a specific amount.

Patent DE-2439650-A1 (DE)
Title: Protective fastening for safety cut-out switch - is released by insertion of pronged key
Inventor: MERKLE PAUL
IPC: E05B29/00
Filed: 1974-08-19
