Abstract: ABSTRACT OF THE DISCLOSURE         A malt high in alpha-1,6-hydrolase(3.2.1.33) for making low calorie beer is produced by germinating previous-ly steeped barley until the average acrospire reaches a length of at least 1 1/4 times the average length of the kernels and it contains at least 55 units of alpha-1,6-hydrolase activity per one gram of malt.  The high alpha-1,6-hydrolase content of the malt makes it useful in con-verting starch to high maltose syrups and in the production of low calorie beer by attacking 1,6-linkages in starch and starch degradation products, such as dextrins.

Abstract: ABSTRACT OF THE DISCLOSURE       The present invention describes a non-skid fenestration sheet material for attachment to a disposable surgical drape.  The sheet material comprising a fibrous base web impregnated with a fluid repellent material and having one planar surface adapted to be secured to the surgical drape and an exposed outer surface treated to provide an abrasion resistant non-skid character. These qualities are imparted to the outer surface by a random array of discrete resin droplet particles in the micron diameter range covering about 5% of the total planar surface area of said web.  The resin particles are of intermediate film stiffness and are effective to frictionally resist sliding movement of surgical instruments and the like resting thereon even when the sheet material is inclined at an angle about 50° and more.

Abstract: ABSTRACT          The present invention is directed to an elec-trical contact designed to effect a crimp termination to an electrical conductor.  Upon repeated engagement of the active contact portion of a prior art crimp-type contact with a complementary contact, the crimp termina-tion may tend to loosen.  Moreover, such contacts must be preassembled to the conductor prior to mounting in a connector housing.  The prior art crimp-type contacts are also generally useful with limited configurations of conductors.  According to the present invention, this is to provide an improved terminal contact element not subject to the above faults and comprising a pair of spaced crimping arms disposed in a common plane and having opposite inside facing edges with beveled sur-faces.  The beveled surfaces provide a camming action during the crimping operation which permits the arms to pass one another and to completely encircle the con-ductor, while the arms remain in substantially the same plane, whereby the crimped arms provide a positive mechanical and electrical connection between the contact and the conductor.  The bight of the terminal element disposed between the spaced arms defines an edge gener-ally perpendicular to the inside edges  of the arms such that the slot defined by the inside edges  of the arms and the bight is generally rectangular whereby the connector may be crimped about electrical conductors  of different cross sectional configurations and  dimensions.

Abstract: Abstract of the Disclosure A compensating arrangement for two aligned, mutually abutting wave guides of identical cross section.  The wave guides have face-to-face arranged terminal flanges and major transverse axes which are offset by an angle with respect to one another.  The compensating arrangement has a plate member inserted between the face-to-face arranged flanges of the two wave guides.  The plate member has an aperture corresponding to the cross-sectional area of the passage defined together by the two wave guides; and two oppositely located capacitive loads extending into the aperture and being symmetrically located with respect to the bisector of the smaller angle defined by the minor transverse axes of the wave guides.  The capacitive loads are reactance members for a broad-band compensation for the discontinuity between the angularly offset wave guides.

Title: Sliding clasp fastener
Inventor: AKASHI SHUNJI
IPC: A44B19/36
Filed: 1979-02-20
Granted: 1982-04-06
Abstract: ABSTRACT OF THE DISCLOSURE         An open end type of sliding clasp fastener has an end stop comprising a pair of lugs formed from a plastic material and secured to the longitudinal edges of respec-tive stringer tapes, each lug having an oblique inner edge extending divergently with respect to the longitudinal axis of the fastener such that the lugs define therebetween a substantially V-shaped opening complementary in shape with the diamond of a slider. One of the pair of lugs has at least one projection contiguous to the oblique inner edge and the other lug has a recess receiving the projection.          The projection extends transversely beyond the central longit-udinal axis of rows of interengaged fastener elements and is disposed for abutting engagement with the slider diamond.          When the diamond moves past the projection and spreads the lugs apart, the uppermost opposed coupling elements become disengaged to allow smooth movement of the diamond there-between.  The advance in the art is that when starting the slider in the fastener opening direction, the tendency of the diamond of the slider to impinge upon the endmost or the next to the endmost fastener elements which are still inter-engaged within the channel of the slider is virtually avoided.          The starting movement is therefore smoother.

Abstract: Abstract of the Disclosure A solution containing cellulose dissolved in a tertiary amine N-oxide solvent containing a nonsolvent for cellulose such as water is shaped by extrusion or other shaping process to form A shaped cellulose fiber, rod, plate, tubing or film.  The extruded shaped article is stretched in air while still a solution to im-part  improved physical  properties  thereto and  the cellulose  is precipitated from the shaped solution to set the properties with-out additional drawing.  The solution may be prepared by dissolv-ing cellulose in the tertiary amine N-oxide solvent in the barrel of an extrusion apparatus,  extruding the solution, orienting by stretching the resulting product in air while still a solution and then precipitating the cellulose  from the shaped article before significant degradation of the cellulose.  The cellulose and ter-tiary amine N-oxide may be ground to substantially the same parti-cle size before charging the extruder barrel.  The tertiary amine N-oxide is recovered and recycled to avoid environmental pollution problems.  The resulting cellulose fibers or films can be used to make fabrics, wrapping or packaging materials or non-woven pro-ducts.

Abstract: A B S T R A C T      The apparent electrical resistivities of various parts of a marine bottom are determined by supplying an alternating electrical current to a pair of current supply electrodes and measuring potential differences between pairs of measuring locations. The locations are on a straight line on the marine bottom. There is a fixed ratio between the distance between the locations of each pair and the distance between said pair and the pair of current supply locations. Adjoining pairs of measuring locations have a measuring location in common.     A flexible cable for taking these measurements is described.     The determined resistivities are subsequently compared with calculated resistivities to determine the compositions and thicknesses of the soil layers of the marine bottom.
