Title: Photograph and negative storage system - uses envelopes with two compartments and placed in rectangular box with lift off lid
Inventor: HEBEL WALTER
IPC: B42F5/00
Filed: 1978-05-02
Abstract: Photographs and negatives are stored in envelopes (3) with two compartments, one for photographs and one for the corresponding negatives.

Title: Cross country or long distance ski - has raised stay section with ski boot support and binding near centre
Inventor: PLENK ANTON
IPC: A63C5/00
Filed: 1978-06-19

Patent DE-2919789-A1 (DE)
Title: Dialling circuit for push-button telephone - transmits standard duration signals independently of speed of button operation
Inventor: DIRR JOSEF ING GRAD
IPC: H04M1/26
Filed: 1979-05-16
Abstract: Irrespective of the speed at which the buttons of a push-button telephone are pressed, the dialling signals must have a specified duration and not less than a min. intersignal pulse. This is achieved by a logic circuit including a units and tens counter driven by an oscillator at approx. 1 kHz. When a button contact closes, the circuit waits 2mS to see if the contact is still closed and then sends the dialling signal for 80 mS followed by a pause. Operation of another button contact during this time is stored until the end of the pause. A second operation of the same button during this time is ignored, i.e. taken to be the same contact operation.
Patent DE-2925401-A1 (DE)
Title: Radial saw for sawing building materials - has roller guide and spring to prevent damage to teeth on return stroke
Inventor: GEBHART SIEGFRIED
IPC: B27B19/04
Filed: 1979-06-23
Abstract: The saw (1), used for cutting building materials such as masonry, pipes, planks etc. is mounted vertically in a frame (2). The saw blade, which is driven by an electric motor through a Scotch yoke, has a taper on the rear edge of its lower end (18). This tapered end is pressed against a guide roller (19) by a tension spring (21). This combination of spring and roller swings the blade (1) away from the workpiece (5) on the return stroke of the saw. This feature reduces the risk of the saw teeth being broken during the return stroke.

Title: Air conditioning elements for buildings - using heat storing water channels in metal or plastic panels (BE 9.2.81)
Inventor: HAFERLAND FRIEDRICH PROF DR IN
IPC: E04F13/08
Filed: 1979-08-11
Abstract: An air conditioning system for a complete building is based on facade elements consisting of metal or plastic panels which are combined with heat storage panels containing channels with circulating water. A portion of this water is stored in a central reservoir in the building from which it is circulated by pumps. The system can be combined with air or water heat exchangers in systems on the heat pump principle, solar heat collectors or other thermal sources. Air ducts can be combined with these panels, with openings for inlet and outlet of air. The panels can be mechanically protected by a sheath of glass fibre reinforced polyester whilst heat loss by conductive bridges is eliminated by hollow neoprene profiles. Such panels can be mass produced, and transported and stored in a small space. Water has a better heat storage capacity than concrete.

Title: Non-dynamoelectric machine incorporating superconducting magnet - uses magnetic attraction periodically to lift weight coupled via belt drive to dynamo
Inventor: HECHFELLNER FRANZ JOSEF
IPC: H02K53/00
Filed: 1979-09-19
Abstract: The machine converts magnetic energy into mechanical energy and hence into electrical energy. Pref. it uses a superconductive magnet to lift a heavy ferromagnetic block on a magnet. A number of pulley wheels are attached to the underside of the latter and cooperate with a set of fixed pulley wheels to form a pulley system for raising a suspended weight, which descends under its own mass, when the superconductive magnet is short-circuited via a superconductive short-circuit switch. The up-and-down movement of the weight is coupled via a belt drive to a dynamo providing the electrical output. The machine is designed to have a high efficiency.

Title: Ultrasonic method to measure fluid flow velocity - using two converters for prismatic couplers outside pipe with signals fed to oscillator controlled time difference detection circuit
Inventor: KOUNO MASARU DIPL ING
IPC: G01F1/66
Filed: 1979-11-22
Abstract: The ultrasonic method for measuring the speed of flow of a liquid (4) through a pipe uses two converter units attached to prisms on either side of the pipe (3). Signals from the converters (1a, 1b). An oscillator (6) signal (UT) passes through the converters to an amplifier (9) to a time difference measuring element (12), with further stages incorporating an inverter (15c), an integrator (14a, 14b), a further converter (15a), followed by a current converter (13) and an integrator (8). The latter (8) receives a synchronising signal from the oscillator (6) through a delay unit (7). The integrated voltage output (E) from the integrator (8) is checked by a comparator (10) against a reference (11, Eo). The compared values give the time difference measurement (12) which is used to derive the velocity value for the liquid from known equations.

One transport roller (3) can pivot w.r.t. the other fixed to the machine frame (5). The pivoted roller is attached to an arm (6) belonging to a frame (8) pivoting on the machine frame about an axis parallel to the axes of the rollers. The other arm (7) of the pivoted frame causes a drivable eccentric element, or cam (9), to separate the rollers (3,4) from one another. The element is a rotating disc or a linearly displaceable cam profile.
