Title: Filter insert formed as a pleated pack and a process for its production
Inventor: MICHAELIS UDO
IPC: F02M35/024
Filed: 1991-01-24
Abstract: A filter element made of non-woven fabric formed as a folded package is self-supporting and is composed of thermally sealable non-woven fabric (1). Each of the two outer edges (3) of the folded package (2) is lined by the non-woven fabric material (1) forming the folds (4), which material, at each folded edge (3), is folded over in the same direction and is fixed to the corresponding bent edge of the adjacent end of fold in a tight fitting manner. The non-woven fabric material overlaps each bent edge of the adjacent end of fold by 1.5 to 2.5 times the fold separation. 
<??>To produce the filter element, the flat filter medium (1) is first folded and then a defined fold separation (7) is produced by a limited stretching perpendicular to the folding. The two outer edges (8) of the folded package are then positively clamped into comb-like sections (9) corresponding to the geometry and dimensions of the folds, and penetrating pincer-like into the folds on the upper and lower sides, the filter material projecting over the shaped sections (9) on each side by 1.5 to 2.5 times the fold separation (7). The overlapping material (10) is folded down on both sides in each case by means of a first pressing element (11) having a sideways action thereon, until the overlapping material (10) fits on the adjacent end of fold, so that the edges overlap. Energy allowing thermal sealing is supplied via these pressing elements (11). Further subsequent pressing elements (12) fix the sealed sites during cooling. The comb-like sections (9) are then removed and the folded package is contracted.

Title: Edible fat-containing composition
Inventor: DE BRUIJNE DIRK W
IPC: A23L33/20
Filed: 1991-02-13
Abstract: L 7231 (R) ABSTRACT            The present invention is concerned with an edible composition containing from 10 to 100 wt.% fat essentially consisting of a mixture of polyol fatty acid polyester having a slip melting point of at least 25°C and digestible fat having a lower slip melting point, wherein the average molecular weight of the molecules comprised by the digestible fat is below 710.            We have found that the negative influence of the inclusion of relatively high melting polyol fatty acid polyester can be reduced substantially by using digestible fat composed of molecules having a low average molecular weight.

Title: Packing and method for producing the same
Inventor: UEDA TAKAHISA
IPC: F16J15/22
Filed: 1991-02-26
Abstract: The packing according to the present invention is composed of a string-like body in which a tape-like packing material having at least one layer is folded in the thickness direction thereof in zigzags with mountain portions and valley portions alternately formed. According to the packing, the string-like body cut into a predetermined length according to the diameter of a shaft concerned may be wound on the outer peripheral surface of the shaft with the width or thickness direction of the string-like body directed in the radial direction of the shaft. Thus, the packing is versatile with respect to the shaft diameter. The packing itself produces no slip in the axial direction of a shaft concerned. This prevents the packing from protruding, thus eliminating the release of stress due to decrease in volume. The packing is used with the string-like body folded in the three-dimensional directions. Accordingly, the shaft-following properties of the packing at the time when the same is worn, are satisfactory and the decrease in sealing properties is restrained.

Filed: 1991-05-24
Abstract: ABSTRACT OF THE DISCLOSURE      An electrode for use in electrochemical ion exchange comprises an electrically conducting element covered by at least two layers of ion exchange material.  The material in one layer differs in its electrical, chemical, or ion exchange properties from that in an adjacent layer. For example a thin layer of cation exchange material underneath a thicker layer of anion exchange material may be used to inhibit the oxidation of chloride ions;  a thin layer of cation exchange material covering a thicker layer of anion exchange material provides an anion-responsive electrode with enhanced selectivity for particular ions. An ion-selective anion-responsive electrode can also comprise a thin outer layer of a very weak base anion-responsive material, covering a thicker layer of a strong base material of lower electrical resistivity.

Title: Child resistant cap with keyway
Inventor: WEINSTEIN JACK
IPC: B65D50/04
Filed: 1991-11-20
Abstract: ABSTRACT    The present invention involves a child resistant closure for containers with threaded necks.  It involves an inner cap and an outer cap which engages with one another by ratchets in order to close but these ratchets do not engage when an attempt is made to open the closure.  The inner cap and the outer cap are generally cylindrical and have sides and a top, although the outer cap may have an open top.  The inner cap has threads on its inside and is adapted to non-removably receive the outer cap so that the outer cap is rotatably engaged therewith.  The outer cap is non-removably but rotatably mounted on an engaged with the inner cap.  Atleast one keyway slot is located either on the outside of the inner cap or the inside of the outer cap and there is atleast one keyway protrusion extending toward the keyway slot and located on which ever of the inner cap and outer cap does not contain the slot. There are indexes on each of the caps and when they are aligned, the keyway protrusion and the keyway slot will be aligned.  The user will align the indexes or indicia and then lift up so that the protrusion fits into the keyway slot.  In this manner, the outer cap engages the inner cap so that they are simultaneously rotated for opening. Upon closure, the protrusion will be pushed or dropped out of the slot and the ratchets will engage for proper closure.
