Title: Gas powered engine
Inventor: NEUKOMM PETER A DR SC TECHN
IPC: F01B27/02
Filed: 1984-12-27
Granted: 1988-01-21
Abstract: A piston of a gas engine is reciprocatingly guided in a cylinder. A gas inlet valve whose valve closure component consists of a ball is situated in the cylinder head. The ball is pushed open in the top dead-center position of the piston by a protrusion formed on the upper portion of the piston in order to admit propellant gas into an expansion chamber formed by the cylinder. The gas engine must be set into operation by turning a crankshaft. If the piston accidentally lies near top dead-center when starting, the piston must be moved against full gas pressure. In order to alleviate starting, a shut-off device is provided which has a start position and an operational position. The shut-off device connects the inlet side of the gas inlet valve with an air conduit opening into ambient air and obturates a pressurized gas container in the start position. The shut-off device obturates the air conduit and clears a gas supply conduit leading from the pressurized gas container to the inlet side of the gas inlet valve in the operational position. With the help of this shut-off device, it is possible to start even gas motors equipped with gear-reduction transmissions.

Title: Apparatus for manufacturing resin-impregnated-fiber braided products
Inventor: KRUESI AUGUST HUGO
IPC: B65H81/00
Filed: 1984-08-30
Granted: 1988-08-04
Abstract: A braid wrapping wheel or carrier is mounted for rotation about its axis and concentrically surrounds a mandrel. The carrier bears rotatable spools of filaments or fiber material about its periphery. One end of each filament is affixed to the mandrel at a point axially displaced from the plane of carrier rotation and the filaments braid about the mandrel during carrier rotation and axial shifting of the mandrel along its axis. A guide ring contacting the filaments intermediate of the spools and the filament contact area on the mandrel define a path of movement for the inclined filaments. A fixedly mounted angular guide ring concentric about the mandrel partially defines a closed plenum chamber bearing a liquid resin under pressure. The resin is fed through fine pores within the ring wall over which the filaments are trained to resin impregnate the filaments. By control of the pressure of the liquid a bead of liquid is maintained at each pore for wiping by the filament during passage with the pressure being insufficient to cause the resin to bleed from the plenum chamber via the pores during filament stoppage or absent the presence of filaments trained about the guide ring. One or more soft rubber scrapers wipe excess resin off the filaments and press the filaments against the mandrel. Alternatively, a number of atomizing nozzles spaced around the guide ring may apply the resin by production of a wet "fog" whose resin droplets quickly wet out the fibers without impinging on the fibers at high velocity.

Abstract: A measuring tube is inserted into a bore hole for measuring underground fluid pressure and is sealed against the bore hole wall for limiting the areas or regions in which the pressure measurement is to occur. A measuring cell is inserted into the measuring tube wall in each of these areas or regions and includes a mobile pressure sensing element against which acts the pressure of the medium surrounding the measuring tube. An end of the pressure sensing element projects into the inner space of the measuring tube and, for measurement, a measuring wheel of a measuring probe is brought into position underneath the end of the pressure sensing element such that the latter is moved radially outwards against the pressure exerted on it. The force which thus acts on the measuring wheel is determined by a measuring device for measuring the pressure. The medium to be measured does not enter or leak into the measuring tube since the measuring cell is sealingly inserted into the measuring tube. The measuring wheel is brought very accurately into the measuring position by the rotation of a central portion of the measuring probe relative to the end portions, which are guided on wheels, and the movement of the probe until it makes contact with stops. This is a prerequisite for high precision pressure measurement.

Title: Method of cutting sheet material
Inventor: ALCANTARA PEREZ BERNARDO
IPC: B23K28/00
Filed: 1986-03-24
Granted: 1989-11-16
Abstract: In accordance with the invention a method in wich N.C. machine is provided to cut sheet material like cloth, paper, cardboard, plastic, plywood, wood and similar chelt materials with a thickness of up to 15 mm. The raw material can be available in the roll form or in laminate planar form. 
<??>To feed material from the roll to the cutting area a motorized support is provided, in the way to prevent the material from stretching or being distorted before being cut in the table. 
<??>In order to have maximum througput from the machine, the cutting table is a conveyor made of an air and gas permeable material, and divided in three areas; feeding, cutting and removing area. Means are provided for the conveyor to prevent it to move during cutting time and to be moved by the X arm without changing the position to each other during feeding operation. 
<??>In each of the cutting and removing areas is an X-Y computer controlled assembly. In the cutting area a plasma jet cutter managed by the X-Y assembly in that way that is posible for the cutting beam to reach every point of the surface. The power suply and the tank for the gas to be transformed in plasma are in a stationary position and the beam path is conveniently protected. The lower side of the feeding and cutting area is covered by a cage from wich air is continuously removed in order to prevent motion of the material to be cut and in order to remove smoke and ofher products that result from the cutting process. Another motive for this cage is to provide means to disipate the energy of the plasma jet beam. 
<??>In the removing area is placed another X-Y computer controlled assembly with a head provided with a labelling and a suction device in order to automatically label and pick-up the cut parts and bring them to a storage area. 
<??>Since normally the minimum length of the marker necesary to make a complete suit is about 5 to 7 m., and, due to the simultaneity of the cutting and removing operation the lenght of the two areas must be the same, a machine to be able to cut the entire marker at once would result extremely long. To avoid the problem, the sistem we are dealing with is provided with a control to cut the marker by sections, normally named "windows" but, and this is very important, "variable windows" in order to cut the patterns falling completely into the cutting area. That is why here, is enough to have the length of the window a little bit bigger that the biggest part to be cut.

Abstract: A vacuum contact system has a vacuum contact frame including a bi-­layer blanket (1) having top and bottom layers (12, 13) spaced apart by a number of parallel strip members (20) to define a first space (19). A bead (14) is positioned around the outer edges of the top layer (12) to support a glass plate (15) so that a second space (17) is formed. Vacuum connectors (16) communicate with the second space and a further vacuum connector (18) communicates with the first space, all the connectors being connected to a vacuum pump (38). The first and second spaces have the atmosphere therein controlled by electromagnetic valves (39, 40) located in a vacuum circuit with the pump (38).In operation a film master (28) and a presensitised material (27) are located in the second space (17) and the vacuum circuit is arranged to remove air from both the first and second spaces (17, 19) so that the two layers of blanket are drawn together. Ridges (30) formed by the strip members (20) are thus formed in the top layer outer surface (12) and these ridges press the film master and presensitised material against the glass plate. The vacuum circuit is then arranged to vent the space between the two blanket layers to atmosphere so that overall contact of the blanket layer (12) is made against the film master (28) and presensitised material (27) which are thus sandwiched between the blanket layer (1) and the glass plate (15) substantially over the whole area of the film master (28).
