Title: Material handling attachment for a tractor having a multiple-point hitch assembly
Inventor: LANGENFELD JOSEPH W
IPC: A01D87/00
Filed: 1987-04-08
Granted: 1992-04-14
Abstract: Abstract of the Disclosure A material handling attachment such as a bucket or the like is pivotally secured to the three-point hitch assembly of the tractor.  The hitch assembly is movable between a lower position and an upper position by means of standard equipment on the tractor.  A mechanical linkage interconnects the bucket, hitch assembly and the tractor so that the bucket will be in a substantially level position when the hitch assembly is in its lowermost position.   As the hitch assembly is moved upwardly relative to the tractor, the linkage maintains the bucket in a level position.  When the hitch assembly reaches its uppermost position, the linkage causes the bucket to be moved to a dumping position.  After the material in the bucket has been dumped therefrom,  the three-point hitch assembly is lowered with the bucket being automatically re-set to its operative or working position.

Inventor: PETERSEN GODBER
IPC: B41F13/68
Filed: 1987-06-10
Granted: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE.        To permit introduction of spreading fingers or insert sheet or sheet packages between essentially adjacent positioned sheet elements or halves (4a, 4b) of a folded sheet, the sheet is folded incompletely by extending a fold or spine or crease line or partly across the sheet while leaving a terminal portion in form of an open loop.  The insert element,which may be spreading fingers (13, 23, 24), spreading disks (25, 26) or another sheet (31), is then engaged within the loop which, after insertion of the insert element, can be compressed,for example by cams (20) to form a crease also in the previous loop position.  The transport of the incompletely folded sheet is carried out by transporting the sheet between, for example, transport belts, with the open loop projecting laterally from the transport belts so that they will not be squeezed or compressed.

Le support tubulaire est muni d'ensembles collecteurs à intervalles  réguliers  et  bobine sur toute sa longueur avec les éléments sensibles et le ruban conducteur. Les différents enroulements sont alors coupés à la bonne longueur au niveau  des  ensembles  collecteurs  et  connectés  électriquement à ceux-ci.

Title: Method and apparatus for constructing circumferentially prestressed structures utilizing a membrane
Inventor: DYKMANS MAXIMILIAAN J
IPC: E04G11/04
Filed: 1987-09-28
Granted: 1992-05-19
Abstract: ABSTRACT         The present invention is directed to improved tank structures and the processes and apparatus for their construction.  The walls of the prestressed tank are formed by inflating a membrane, applying one or more layers of rigidifying material outwardly of said membrane and then prestressing the walls by circumferentially wrapping prestressing material to minimize the tension in the rigidifying material when subject to loading.  In another embodiment, wall forms are placed inwardly of said membrane to aid in the forming of the walls and circumferential prestressing.  In the best mode of the invention, the walls are of fiber reinforced plastic, or resin sandwich composite construction.  Seismic countermeasures may also be used to protect the structure against earthquakes and other tremors, by the anchoring of the tank walls to the base and permitting the seismic forces to be shared by the seismic anchors.  When a seismic disturbance occurs, the force acting on the structure can be transmitted and distributed to the footing and around the circumference of the tank.

Title: Metal can end for cans whose contents are under inside pressure
Inventor: SCHMIDT GUNTER H R
IPC: B65D17/32
Filed: 1987-11-17
Granted: 1992-06-30
Abstract: Abstract Metal can end for cans whose contents are under inside pressure A can end (1) made from sheet metal for cans whose contents are under inside pressure is provided with at least one opening tab (4) partly punched from the end leaving a hinge area (6) and a relative aperture (2) formed by the partial punching, with the opening tab (4) and/or the area of the end surrounding the aperture (2) being cold formed so that the edge area (8) of aperture (2) covers the edge area (4a) of opening tab (4) on the end outside (1a). On the end inside (1b), plastisol (10) is applied in ring-form to the edge areas (4a, 8) of opening tab (4) and of aperture (2) and gelled under heat. Before its application and gelation respective-ly, the plastisol (10) has a viscosity ??D441s-1 (40°C) of about 2000 - 2800 mPa.s, and an edge angle ? of about 0.4 - 1.0 N/mm2, and a maximum elongation of 120 - 250 % (fig. 2a).

Title: Modularly expandable desktop keyboard
Inventor: KUBA LAWRENCE M
IPC: H05K5/00
Filed: 1987-11-25
Granted: 1990-11-06
Abstract: ABSTRACT OF THE DISCLOSURE            A modularly expandable keyboard has expansion modules which are integrated into an elementary keyboard by means of locking tongues inserted in depressed tracks in the modules and held in place by detents in the attached modules.  The detent mechanisms are formed integrally with the housings of the modules and are unstressed when fully engaged.  ~n electrical interconnect plug integrates the electrical buses of attached modules.  Modules can be attached to either right or left and additional modules can be attached to already attached modules indefinitely.

Inventor: SCHWYN BERNHARD
IPC: B29C43/08
Filed: 1988-05-12
Granted: 1991-08-20
Abstract: ABSTRACT OF THE DISCLOSURE:            In an installation for producing packaging containers such as tubes, from prefabricated tube bodies and end portions of thermoplastic material, which are connected to the tube bodies,  a plurality of moulds which are moved on a circulatory path each comprise an upwardly directed female mould portion and a mandrel which is pivotable about a horizontal axis between a downwardly directed working position and a loading position.   A tube body loading station, a material feed station having a nozzle, and a container unloading station are arranged at spacings from each other along the circulatory path, while actuating means displace the female mould portion and the mandrel of each mould relative to each other on a common working axis.  In a plurality of working units comprising support frames which are moved on the circulatory path,  each support frame supports at least the female mould portion and the mandrel of a mould and the actuating means thereof.  The female mould portions and the nozzles are movable relatively to each other and transversely relative to the circulatory path into a common axial position.

Title: Process for the production of high purity tartaric acid
Inventor: BOSCH RICHARD J
IPC: C07C59/255
Filed: 1988-07-12
Granted: 1993-04-06
Abstract: PROCESS FOR THE PRODUCTION OF HIGH PURITY                  TARTARIC ACID    ABSTRACT         Disodium tartrate which can be easily converted to tartaric acid is produced by hydrolysis of an epoxysuccinate.  Formation of impurities is minimized and the reaction time shortened by performing the hydrolysis under superatmospheric pressure and elevated temperature at a pH in the range of from about 6 to about 11.
