Abstract: A portable index card holder is designed for carrying in notebooks or simply carrying by itself. The holder comprises a flexible member approximately the size of a notebook page having secured to its front surface a plurality of transparent sheets in an overlapping array between the top and bottom of the supporting member. These transparent sheets each includes small strip overlays defining front and rear pockets for receiving and supporting the lower marginal edge of an index card in such a manner that any one card can easily be inspected by simply lifting up the sheets above the same. The transparent feature permits reading both the front and rear sides of an index card without having to remove the same from the transparent sheet and holding member. Further, several such members can readily be inserted in a notebook such as a 3-ring binder for organizing many different cards in conjunction with other items.

Abstract: Apparatus for unthreading collars from casing and tubing or the like employed in bore holes, and including a chuck adaptor to be mounted on a lathe. The chuck adaptor has a shaft which is held by the chuck of the lathe. The shaft carries the housing in which three eccentrically apertured contiguous rings are mounted. The center ring is rotatable in the housing whereas the two other rings are fixed therein. A slot is provided through the housing at the position of the center ring. A handle-like projection extends from the exterior of the housing through the slot and is threaded into the rotatable ring. Gripping dies are carried internally of the rotatable ring. The fixed rings hold the collar while the center ring is rotated by rotating the projection to cause the gripping dies to seize upon the collar. The lathe turns the adaptor while a wrench engaged with the pipe threaded to the collar may be held stationary. The center ring is turned about an axis which is eccentric to that of the aperture therethrough.

Abstract: The captive screw has an enlarged head to prevent complete passage of the screw through a bore in a panel. The shank of the screw has a side opening incorporating a retractable latch radially extending from the shank. This latch has upper and lower sloping cam surfaces at its forward end. The lower surface is oriented such that urging of the screw inwardly through the bore in the panel retracts the latch. The latch is spring-biased radially outwardly so that after the latch clears the bore, the screw is held captive. The upper cam surface of the latch intercepts the lower cam surface in a line which is tilted at an angle corresponding to the helix angle of the threads in a nut receiving the screw in an adjacent panel. The screw can thus be threaded into this nut to close the panel and the latch will function as a thread lock.

Abstract: The invention provides a major improvement in the application methods of various materials adhered to the nail for purposes of strengthening natural nails, artificial nail tip extensions or both, in part by eliminating an unnecessary and time consuming application step. A strip of nail overlay has one side coated with pressure sensitive non-permanent bonding adhesive and it is permeable to permit the passage of bonding glue. A strip of release backing paper is superimposed on and secured to the nail overlay--and is arranged to be separated from it after sections of the superimposed strips have been cut to the general outline of a human nail. A coat of glue is applied to the top of the nail overlay to bond it to the human nail.

Abstract: A hemispherically shaped cover is provided for a beverage cup and includes a top opening smaller than the normal opening of the cup itself. Beverage can be received through this top opening to fill the cup, the cover itself inhibiting spilling of the beverage over the upper rim of the cup. The same top opening is also used to receive a straw and permit a person to drink the beverage without having to remove the cover.

Abstract: A sectional and adjustable bracket for hanging drapery and other wall covering fabrics has an elongated holding bar that holds removable hanger units. The hanger units are shaped to form fabric pleats and include rearwardly extending shoulders. The holding bar is formed with stabilizing slots sized to receive the shoulders and prevent them from wobbling and moving laterally. The top edge of the holding bar has prongs and the top edges of the hanger units have spikes to pierce the fabric margin and support the fabric in place.

Abstract: A locking mechanism operates to selectively lock and unlock a pair of telescopic tubes. A lock base is fixed to one tube and is formed with an eccentric pin. A lock ring is slidably disposed within the other tube and is slipped over and carried by the eccentric pin. The external configuration of the lock pin and cross section of its associated tube are polygonal or multi-sided to prevent relative rotation. By relatively rotating the tubes in only one direction locking is accomplished and by relatively rotating the tubes in just the opposite direction unlocking is effected. The overall end-to-end length of the tubes can be adjusted by unlocking them, sliding one axially relative to the other and then locking them again.

Abstract: A collapsible framework or chassis equipped on top with a trackway is mounted on a trailer which may be transported from place to place to assist in servicing vehicles. The framework may be alternately collapsed and maintained in a low profile during travel conditions and expanded to full height while supporting the vehicle on its trackway so that the underside of the vehicle can be serviced, e.g., muffler repair or installation. A control means first raises the front portion of the collapsible framework after the vehicle drives from a ramp onto the trackway and thereafter raises the rearward portion of the collapsible framework to thereby position the vehicle for servicing.

Abstract: The new avocado tree is characterized by its relatively greater usefulness compared to the Topa Topa as a root stock and in prevention of chlorosis in soil conditions where trees are prone to become chlorotic.
