Title: Method for producing infusion coffee filter packs
Inventor: REHMAN WARREN C
IPC: B65B29/02
Filed: 1990-09-20
Abstract: A method is disclosed for producing infusion coffee filter packs in which a first strip of filter paper is placed adjacent to a mold having a cylindrical mold pocket, and the strip of filter paper is caused, either mechanically or by a vacuum, to conform to the cylindrical mold packet. The conforming step causes the surface area of the first strip of filter paper to stretch and increase by at least three percent relative to its area prior to the conforming step. A measure quantity of ground coffee is then deposited into the mold packet over the filter paper conformed thereto. A second strip of filter paper is placed over the first strip of filter paper and the ground coffee in the mold packet. The first and second strips of filter paper are then sealed together around the coffee filled mold pocket, as by a heat sealing press pressing and sealing the strips together. The filter paper is then trimmed as by die cutting to product a half inch wide flange area extending around the mold pocket. The presence of the one half inch flange in combination with the increased surface area caused by stretching results in a brewed coffee having an increase in soluble solids extraction and a decrease in the standard deviation of soluble solids extraction.

Abstract: The assembly includes a lock with a main lock body having a bottom keyhole and an inverted u-shaped double rung top hasp connected to the top of the main body and extending upwardly therefrom.  The assembly also includes a flexible, resilient, elastomeric protective lock cover removably enclosing and sealing the lock body against the elements.  The cover is in two pieces.  It includes a bottom portion extending over the lower sides of the lock body and continuing below the lock body.   The bottom portion has opposed sides and a tapered bottom defining an openable closed slit through which, when opened, by squeezing opposed sides toward each other, the keyhole can be reached by a key.  The cover also includes an upper cap having a top and interconnected depending sides. The inner surfaces of the cap sides bear a circumferential groove engageable with and of smaller diameter than the base of a circumferential bead with sloping top and bottom on the outer surface of the sides of the bottom portion.  The groove and bead are horizontal and, when engaged, releasably hold the cap sealingly to the bottom portion.  The top includes hasp holes into which downwardly projecting circumferential sealing extensions depend.  The cover may be shaped to fit a flat, rectangular or square lock or a circular (in outline) lock and the cap top may include a hasp hole groove to facilitate movement of the free end of the hasp over the top.

Abstract: Abstract Disclosed are the immunochemical properties of  a  17  kDa protein  antigen  fractionated, purified  and  sequenced  for amino  acids  from Mycobacterium tuberculosis  (South  Indian isolate,  SII  1) which causes human  tuberculosis worldwide among 16 million patients.  The 17 kDa protein antigen  which has  an  N-terminus of A T T L P V Q R (aa 1-8)  has  atleast three  specific antibody binding epitopes located  on  linear peptides of sequences,  R A T Y D K R Y E V R (aa 91-101)  and S  E F A Y G S F V R (aa 68-77) which were useful in a  micro ELISA  for the early diagnosis of human tuberculosis  by  the detection of specific antibodies.  The 17 kDa protein antigen which was mitogenic for human tuberculous  peripheral  blood lymphocytes  was  found  to  carry  three  predicted   T-cell epitopes on linear peptides of sequences, S E F A Y G S F V R          (aa 68-77) and A E L P G V D P D C D V C I T R (aa  107-122).          The 17 kDa antigen of M. tuberculosis (SII 1) which thus  had both  B and T cell reactive properties was found  to  contain 131  amino  acids and potentially applicable  in  the  immuno diagnosis,  immuno  therapy and immuno prophylaxis  of  human tuberculosis.

Filed: 1990-12-27
Abstract: In  a  radio  communication  apparatus  which  is capable of using a selected terminal unit selected from a plurality of terminal units, a logic part detects the kind of the selected terminal unit to produce a type signal representative of the selected kind.   Responsive to the type signal, the logic part controls an adjusting part which produces an adjusted signal.   As a result,  the adjusted signal has a selected level which is selected for the selected terminal unit in accordance with the type signal.  Responsive to the adjusted signal, the selected terminal unit generates an audible signal having a volume which is adjusted in accordance with the selected level. Additionally, the volume can be manually adjusted by an operator.

IPC: G11B33/14
Filed: 1991-01-16
Abstract: A magneto-optical recording device has a flying head that floats over a magneto-optical disk according to the rotation of the magneto-optical disk.   The  flying head includes a head slider.  A solid lubricant is applied to the  bottom  surface  of  the  head  slider  facing  the magneto-optical disk.  Since the solid lubricant makes the flying  head  contact  with  the  magneto-optical  disk smoothly, the scratching and wear of the magneto-optical disk  and  the  flying  head  decrease.   Therefore,  the reliability  and  the  durability of  the  magneto-optical recording device can improve.   Physical protrusions and recessions or holes containing fluorocarbon oil therein may be formed instead of the solid lubricant.   In this case,  the contact area between the flying head and the magneto-optical disk is also smaller than the case where physical protrusions and recessions are not formed.   In addition, with a configuration such that thin-film layers made of a fluorocarbon resin having an excellent lubricity are formed on both sides of the bottom surface of the head slider, since the magneto-optical disk comes into contact with the head smoothly, the reliability and the durability of the magneto-optical recording device can improve.

Title: Surgical instrument
Inventor: KRAUSE KENNETH W
IPC: A61F2/06
Filed: 1991-02-06
Abstract: A surgical instrument that includes a rigid outer member within which is disposed a hollow inner member having rigid proximal and distal ends and a region disposed between the rigid proximal and distal ends that is relieved to render such region relatively flexible. The flexible region is integral with a portion of the proximal end disposed adjacent to the flexible region. The inner member transmits force (such as torsion) applied to its proximal end to move a cutting implement disposed at its distal end to cause it to cut tissue admitted through an opening in the distal region of the outer member. In another aspect, a region of the inner member is weakened (eg. by relieving an integral region of the member) with respect to the remainder of the inner member to cause this region to break if the force (eg. torque) applied to the inner member exceeds a predetermined threshold.      In yet another aspect, the flexible region is relieved by forming openings therein, and pliable material (such as silicone rubber) is disposed in the openings.
