Title: Gradient and polarizing field compensation
Inventor: GLOVER GARY H
IPC: G01R33/3875
Filed: 1989-02-09
Granted: 1992-06-23
Abstract: GRADIENT AND POLARIZING FIELD COMPENSATION Abstract of the Disclosure A method is provided for characterizing the spurious, time dependent magnetic field gradient response and for compensating therefor.  In accordance with the method, two small sample objects are placed at two positions with respect to the system isocenter where the gradient to be compensated has different values.  A magnetic field gradient pulse is applied to the sample, followed by the application after a variable time of a 90° radio frequency pulse.  The phase of the resulting free induction decay (FID) signal is monitored as a function of total time since the end of the gradient pulse.  These data are related to the impulse response of the gradient and are employed to construct compensation filters for both the gradient coils and the polarizing field shim coil.

Title: Fluid handling device with filter and fabrication process therefor
Inventor: KNEEZEL GARY A
IPC: B01D29/01
Filed: 1989-08-17
Granted: 1993-08-17
Abstract: ABSTRACT OF THE DISCLOSURE   Relatively small fluid handling devices having a filter bonded on the surface containing the fluid inlets. An example of such a device is a thermal ink jet printhead. A substantially flat filter is placed at the ink inlet to the printhead by a fabrication process which laminates a wafer sized filter to the aligned and bonded wafers containing a plurality of printheads. The individual printheads are obtained by a sectioning operation, which cuts through the two or more bonded wafers and the filter. The filter may be a woven mesh screen or, preferably, an electroformed screen with a predetermined pore size. Since the filter covers one entire side of the printhead, the relatively large contact area prevents delamination and enables convenient leak-free sealing. The filter prevents the entrance of contaminants into the relatively large inlets of the printhead at an early stage of assembly and packaging.

Abstract: The present invention provides a female coupling member for use with a male coupling tenon having a free end, a narrow interconnecting shank and a root end all arranged in mutually axial relation with the shank interconnecting the free end and the root end.  The female coupling member comprises two adjacent side walls having mutually opposed, convergent faces defining an opening therebetween, through which the shank of the male member extends with the free end positioned within the interior of the coupling member.  Axial tensioning of the coupling urges the free end of the male member against the converging faces of the two side walls, in wedged interfering relation.  Forces exerted on these faces by tensioning of the coupling are distributed from the female member into adjacent portions of the panel.

Title: Procedure for the bleaching of pulp involving the use of laccase, a lignin-modifying oxidation-reduction enzyme
Inventor: VAHERI MARJA
IPC: D21C9/10
Filed: 1989-09-18
Granted: 1995-04-11
Abstract: The invention concerns a procedure for the bleaching of pulp, in which procedure an oxidating bleaching chemical containing chlorine is used.  The essential feature of the invention is that the pulp is treated, either in conjuction with or before oxidation, with a lignin-modifying oxidation-reduction enzyme, such as the laccase produced by the white-rot fungus.  The oxidating bleaching chemical used in the procedure may be chlorine dioxide or a mixture of chlorine dioxide and chlorine gas.  The use of said enzyme reduces the amount of chlorophenols and other forms of organically bound chlorine in the bleaching effluent, simultaneously lowering its chemical oxygen demand.

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus  for wet  laminating  a  photopolymerizable film onto circuit board panels or other substrates.  The apparatus  is  easily  and  quickly  convertible  from  dry laminating to wet  laminating with the rollers  therefor mounted in bearing blocks which are insertable in slots in brackets at each end and removable therefrom.  The lower roller thereof has a gear the teeth of which are meshable with  the  teeth  of  an  idler  gear  for  transmission  of rotation power thereto.   Elongate tubes  for applying a fluid, which comprises between about 0.1 and about 10 wt. % of a heterocyclic metal-chelating agent,  to the wet insertion rollers for application thereof to the panels are contained in a yoke which is adjustable next to wet insertion rollers  for wet  laminating or away  from try insertion rollers for dry laminating.  The flow rate of fluid to the elongate tubes  is  controlled,  and excess fluid applied to the wet insertion rollers is collected in a tray and returned to the system in order to prevent waste   and   undesirable   environmental   effects.    In accordance  with  an  alternative  embodiment,  fluid  is applied  to  a  substrate  by  a  first  pair  of  insertion rollers and the amount of fluid retained on the substrate is regulated by applying and regulating a pressure between a second pair of insertion rollers and the substrate.  The lower  of  the  first  pair  of  insertion  rollers,  which transmits driving force to the second pair of insertion rollers, comprises a roller member removably attached to a pair of fixedly mounted stub shafts so that it may be easily removed and replaced for conversion between wet and dry lamination.

Abstract: A sleeve-type beverage can carrier having end dust flaps which mechanically interlock by means of locking tabs and cutouts. The flap containing the cutouts overlaps the flap containing the locking tabs so that the cutouts and tabs are aligned. The locking tab is folded back to allow the flap with the cutouts to be moved into place, then is inserted through the cutout and also through the portion of the bottom flap from which the locking tab was struck. This provides a secure mechanical lock. In addition, the blank from which the carrier is formed is designed so that the space between dust flaps is identical in shape to that of the dust flaps. This allows multiple widths of blanks to be cut from the sheet stock without scrap loss.

Abstract: Packaging envelope or packaging bag consisting of at least two plies, of which the one ply is elastic and the other ply is a gas-barrier layer. The inner ply can consist of a food-compatible material, so that foods, in particular meat, can be placed in the packaging envelope or the packaging bag. For packaging, the envelope is expanded and the object then inserted. After the insertion, the envelope contracts through its flexibility in the direction of the center line of the envelope and automatically presses the air present between object and envelope out of the packaging. In the packaging of shapable objects, in particular meat, the envelope presses these objects, in particular the meat, simultaneously into an at least approximately circular cross-sectional shape through the exerted radial forces. The gas-barrier layer prevents the entry of air through the envelope material even for a lengthy storage period.
