Title: Improved pressure monitor
Inventor: BITETTI RODOLFO
IPC: H01H35/28
Filed: 1988-04-23
Abstract: A pressure monitor (1) is described which has a first chamber (2) which can be acted on by a pressurised fluid and in which means (3) are arranged which can be deformed elastically by tripping and open or close the electrical contact between two contact elements (30; 32) depending on whether the pressure of the fluid is greater than or less than a predetermined nominal value. The pressure monitor is provided with a cap (16) which has an axial opening which bounds a second chamber (23) in which the parts of the connectors (5; 6) involved in the contact are located, as well as a third chamber (34) which is connected to the exterior and is sealed by an elastically deformable diaphragm (membrane) (22) from the chamber already mentioned, it being possible for the diaphragm to expand into this third chamber (24) if an overpressure occurs in the second chamber (23) as a result of a temperature rise of the fluid which is enclosed in a hermetically sealed manner in this second chamber. <IMAGE>

Title: Bucket body for devices for producing a propulsion force
Inventor: KADEN HELMUT
IPC: B63H16/04
Filed: 1988-05-19
Abstract: The invention concerns a bucket body for devices for producing a propulsion force by acting on fluidic media - in this case water - and relates in particular to paddle blades as used for producing a propulsion force for the propulsion of boats in the water. It is known that the paddle blades mounted on the end of the so-called oars, as bucket bodies of different production methods and materials, are plunged into the water, are pulled through the water, are lifted out at the end of the section of movement, are returned outside the water and are plunged in again in order to produce a propulsion force. The number of oar strokes per unit of time and the force applied by the rowers determines the speed of the boat and the endurance of the rowers. In the previous rowing paddles, a portion of the expenditure of force of the rowers is ineffectively lost due to the water flowing over the paddle rims and is thus consumed uselessly and ineffectively. By the fitting of nozzles in the oar blades and the flow constraint of the water through the nozzles, the force-consuming flow of the water over the paddle rims is reduced. Due to the conserved effort of the rowers, the flow rate of the water through the nozzles is increased and the reaction effect is produced on the paddle. The reaction force coming into effect via the long lever arm of the paddle relieves the strain on the rowers and accelerates the ... Original abstract incomplete.

Title: Device and method for measuring the size or for monitoring the wear and the number of bodies which are entrained in flowing liquids
Inventor: KOLLER JOSEF DIPL ING
IPC: F28G1/12
Filed: 1988-08-17
Abstract: In measuring the size or monitoring the wear of bodies 5, preferably spherical cleaning bodies 5, as they are entrained in cooling water in the case of cleaning cooling tubes of a tubular heat exchanger, the cleaning bodies 5 in the cleaning body transport tube 4 pass a light beam 3 of a light barrier 1, 2. The size of the light beam 3 is selected such that cleaning bodies 5 which by virtue of size still have a cleaning effect completely interrupt the light beam 3, whereas the worn cleaning bodies 5 do not. The signals which are generated in the case of complete interruption of the light beam 3 are counted and compared at specific time intervals with a desired value. If the desired value is not reached, the worn cleaning bodies 5 are replaced by new cleaning bodies. In the monitoring of the number of cleaning bodies 5, all the cleaning bodies 5 are counted and are compared at specific time intervals with a desired value. If the desired value is not reached, too few cleaning bodies are in circulation. Measuring and counting are performed statistically, i.e. only a partial quantity which behaves in a manner analogous to the total quantity of cleaning bodies 5 is detected. <IMAGE>

Title: Ram-shaped baling press - can counteract overfilling and has triangular shaped projection on front face of ram to exert downward force on material
Inventor: RIEPE RAINER
IPC: B30B9/30
Filed: 1989-12-12
Abstract: In a baling press the material tends to build up in front of the ram (6) as it moves forward and projects into the filling chamber (13). This excess is sheared off when the blade (17) at the front of the ram meets the fixed blade (18) at the end of the filling chamber. With sheet material such as newspaper the amount to be sheared may become excessive so that the ram comes to a halt. The front face of the ram has triangular shaped projections (22) which cause a counteracting downwards force to be exerted which limits the build up of material to an amount which can easily be sheared. USE/ADVANTAGE - Simple design. Avoids need for tamping. Better press utilisation.
