Title: Apparatus for severing and dedusting webs of paper or the like
Inventor: HUSER PETER
IPC: B26D7/18
Filed: 1990-02-28
Abstract: ABSTRACT         A web of paper, cardboard, foil or textile material is pulled against and between two rotary knives which sever the web longitudinally and form a slot as well as dust.  Such dust is removed by a pneumatic mechanism having one or more nozzles which discharge one or more streams of compressed ionized air against the upper side of the web in the region of the slot, and a suction chamber disposed beneath the path for the web, extending across the slot beneath the nozzle or nozzles, and having one or more suction ports which enable the chamber to collect the particles of dust.  The port or ports further enable the chamber to collect those fragments of the web which adhere to the separated sections of the web in the region of the slot between such sections.

Title: Balancing method and product
Inventor: EHRICH FREDRIC F
IPC: G01M1/16
Filed: 1990-05-10
Abstract: A low-speed balancing method ins provided for balancing a rotor to introduce balance corrections for reducing unbalance due to operation of the rotor at or near critical speeds without actually balancing the rotor at such critical speeds. The method is applicable for balancing a rotor in three, faun or more correction planes by utilising combinations of generic unbalance distributions of the rotor and predetermined mode shapes of the rotor at critical speeds: A simple method is presented which allows an operator using a low-speed balancing machine to determine measured corrections applicable to two plane of the rotor and then the operator effects at least a third correction to the rotor which is proportional to the first and second measured corrections and the unbalance/mode shape combustion. The operator then repeats the low-speed balancing sequence to determine final corrections at the first and second planes, which are then made for finally balancing the rotor.

Abstract: NOZZLE ARRANGEMENT IN A BLOW BOX OR PIPE OR A PAPER MAKING MACHINE                     ABSTRACT OF THE DISCLOSURE          A nozzle arrangement in a blow box of a paper machine, comprising one or several nozzles (22a, 22b) placed in connection with the blow box (20) or pipe, through which nozzles a blowing of air can be applied to a moving member in a paper machine placed in their proximity, such as a wire, drying cylinder, guide roll, felt, or the equivalent.  The blow box (20) and its nozzles (20a, 20b) are at a certain operational safety distance (C) from the moving member. In connection with the nozzle slots of the nozzles (22a, 22b) or nozzle, a respective nozzle flap (24a, 24b) pivotable around a respective transverse hinge shaft (P) is hinged.  The nozzle flaps (24a, 24b) respectively guide the blowing of air (Fa, Fb) to the desired object and if necessary maintain a required difference in pressure.  The nozzle flaps (24a, 24b) are hinged in such a way that, in their normal operating position, the outer edge of the respective flap is at a distance considerably shorter than the required operational safety distance from the moving member (10, 12), but the nozzle flaps (24a, 24b) can pivot to the required safety distance when a paper clod or some other obstacle passes by.

Title: Facility for storing items along parallel channels
Inventor: GOLDSCHMIDT SOL
IPC: B65G1/06
Filed: 1990-06-22
Abstract: ABSTRACT      A warehouse has several levels.  Each level has a series of storage channels for items to be stocked in the warehouse.  The storage channels are parallel to one another and have respective inlet ends located at a first side of the warehouse and respective outlet ends located at an opposite second side of the warehouse.  Each storage channel is equipped with a device for guiding items along the channel in a direction from the inlet end towards the outlet end.  Every level is further provided with at least one return channel which is parallel to the storage channels and has an inlet end at the second side of the warehouse and an outlet end at the first side of the warehouse.  The return channel is again equipped with a device for guiding items along such channel in a direction from the inlet end to the outlet end thereof.  On each level, a reversible first horizontal transporting mechanism extends by the channels on the first side of the warehouse while a reversible second horizontal transporting mechanism extends by the channels on the second side of the warehouse.  An elevator is disposed on both the first and second sides of the warehouse adjacent to the respective horizontal transporting mechanisms.  The return channels make it possible to transport an item from the outlet end of a storage channel back to the inlet end along a loop located on the level of the storage channel.  Thus, if an item to be shipped is disposed behind one or more other items which are to remain in storage, the latter items are simply conveyed along the respective loop.
