Title: Compressed air engine for vehicle propulsion - has central power cylinder with piston forming unit with compressor pistons
IPC: F02B71/00
Filed: 1978-06-16
Abstract: The engine has a central power cylinder forming a unit with air suction and compression pumps. The power cylinder piston forms a unit with the pump pistons. The pistons can be of the free type, and the power piston can have a protrusion shutting off the fuel inlet at the appropriate moment. The sparking plugs can be mounted on the piston itself, on the protrusion, which also has a contact working with one inside the fuel inlet to give ignition at the appropriate moment. The design can also be such that the ignited fuel never has the chance to escape completely, thus giving more complete combustion.

Title: Electronic pigeon race recorder - has sealed container for collecting data carrier bearing competition number and upon which time information is recorded
IPC: G07C1/26
Filed: 1981-04-24
Abstract: The electronic pigeon-recorder system cooperates with a data carrier bearing a competition number, pref. in code form, the cooperation being such that the carrier registers electronically on the recorder a time-observation using a built in clock. In its simplest form, the carrier is a magnetically susceptible strip on a ring which is carried on a pigeon's foot. This is stripped off the pigeon's foot and put in the recorder which wipes off any previously recorded data and a time registration is recorded using a writing head. The ring then drops into a collecting tray. When the competition is finished, the recorder is handed in, the race clock is depressed and the seal broken. The collected ring is then read to ascertain the time of clocking-in of the ring. the serving and recording is done visually, optically or electrically.

Title: Greenhouse with an improved distribution of glazing bars
IPC: A01G9/14
Filed: 1992-12-09
Abstract: The invention relates to a greenhouse provided with an enclosure with panes and bars. The bars have the function of absorbing the loads acting on the panes. The loads on the panes differ at the various locations on the roof. The distribution of the bars differs at the various locations on the roof. In the conventional distribution, 1/1, 1/2 and 1/3 pane width is used. At the location of the windows which are to be opened, it is impossible to use 1/2 pane width, since this conflicts with the actuating mechanism of the windows which are to be opened. Consequently, there are unsupported bars. The invention comprises a change to the distribution of the bars, so that there are no longer any unsupported bars. In this case, the load on the bars is as uniform as possible at the various locations. By adapting the distribution it is also possible to make do with fewer bars, so that less light is blocked.
