Abstract: A resistance apparatus for use with exercise devices includes an axle and outer housing for rotatably mounting the axle therein. At least one inner housing includes an opening for receiving the axle therethrough so that the inner housing is fixably mounted on the axle. The inner housing is rotatably mounted inside the outer housing to permit rotation of the inner housing along with the axle within the outer housing. At least a first tensioned member is disposed within the inner housing. The first tensioned member includes a first end and a second end. The first end of the tensioned member engages an engagement area of the inner housing. The second end of the tensioned member engages an engagement area of the outer housing. The tensioned member creates a rotational restoring force between the inner housing and the outer housing.

Abstract: A system for pivotally coupling two elements of a portable computer is disclosed. The system includes a hinge pin for pivotally coupling the two elements. The hinge pin includes a rod having a main axis and a first outer diameter. The hinge pin further includes a bore in a proximal portion of the rod having a first inner diameter, wherein the bore is aligned along the main axis. The hinge pin further includes a distal portion of the bore having a second inner diameter larger than the first inner diameter. The hinge pin further includes a groove stop within the bore, providing a surface for pulling the hinge pin along the main axis in a proximal direction. The system further includes a tool for extracting the hinge pin from the two elements, allowing the hinge pin to be pulled along the main axis in a proximal direction.

Abstract: In a process for working up polyether monools which have been prepared by ring-opening polymerization of epoxides by means of OH-functional starters using at least one heterogeneous catalyst, the heterogeneous catalyst or catalysts is/are separated off from the polyether monool by means of a membrane separation process.

Abstract: An interment vessel is designed to be capable of transoceanic travel. A body for the vessel is buoyant and self-righting. The vessel has a sail disposed diagonally across its upper surface, relative to a keel along the bottom, providing propulsion under power of prevailing winds. Crematory ashes can be placed in the body of the vessel, either into an opening in the body which is thereafter sealed, or into a sealable container or urn arranged to be carried by the vessel. A provision to store and display a removable reward can be provided as an incentive for a finder of the vessel to return the vessel or the container/urn to the decedent's family or the like. Instructions can be provided, for example detailing the address and mentioning a further reward.

Abstract: A method of preventing or treating posttraumatic nervous injuries by administering a compound of the formula: ##STR1## wherein R.sub.1 is hydrogen, a lower alkyl group, cyclohexyl or benzyl; Z is one of the groups ##STR2## if Z is a group (a), R.sub.2 and R.sub.3 together represent an additional bond between the carbon atoms bearing them, or if Z represents a group (b), R.sub.2 is hydrogen; R.sub.4 is hydrogen or lower alkyl; R.sub.5 is hydrogen, lower alkyl or phenyl, and R.sub.6 is hydrogen or methyl. Hydrates or pharmaceutically acceptable acid addition salts may also be used in the method. Pharmaceutical compositions used in this method containing such compounds in a prophylactically or therapeutically effective amount may be administered by infusion, injection, orally, perorally, rectally, percutaneously or other route.

Abstract: A method of treating patients suffering from amyotrophic lateral sclerosis (ALS) by administering dipeptide derivatives of the formula ##STR1## wherein R.sub.1 is hydrogen, a lower alkyl group, cyclohexyl or benzyl; Z is one of the groups ##STR2## wherein if Z is a group (a), R.sub.2 and R.sub.3 together represent an additional bond between the carbon atoms bearing R.sub.2 and R.sub.3, or if Z is a group (b), R.sub.2 is hydrogen; R.sub.4 and R.sub.5 are hydrogen or lower alkyl, or R.sub.5 may also be phenyl; and R.sub.6 is hydrogen or methyl; hydrates or pharmaceutically acceptable acid additions salts thereof.

Abstract: A testing arrangement for a printed circuit board includes a carrier for a multiplicity of contact pins which engage the ends of the printed conductors on the printed circuit board. The carrier is positioned above a base which receives a multiplicity of leads connected with a device for testing the printed circuit board. The leads, which are to be connected with respective ones of the contact pins, engage sockets mounted in the base. The connections between the contact pins and the leads are established via a sheet which is located intermediate the base and the carrier and is provided with contacts in the form of thin foils. The contacts face and engage respective ones of the contact pins. The contacts are connected with plugs which are mounted on the intermediate sheet and are inserted into the sockets in the base.

Abstract: For joining a wishbone boom to the mast of a sailboard there is provided a connector having a body to which is pivotally joined a pair of sockets for receiving the mast ends of the wishbone, the sockets straddling a pair of complemental semi-cylindrical jaws pivotally mounted on said body and arranged to embrace a mast. When the sockets are positioned generally normal to the longitudinal elements of the jaws the latter are urged together by the sockets to clamp on the mast. Moving the sockets as a unit through an arc relative to the body and jaws releases the jaws so that they can separate and release the mast.
