The drive shaft for the single shiftable drive gear is turned by an external knob on one side of the calendar housing.

Abstract: A bubble blowing toy features two bubble blowing loops connected by a common support member essentially tangent to the loops, with the loops disposed in perpendicular planes. The loops produce different types of bubbles. While one loop is being used to produce bubbles, the opposite end loop serves as a handle.

Abstract: Refuse delivered into an elevatable pivoted dumping bin is transferred by gravity and by the operation of a positive pusher element into a hopper bin above and in communication with a horizontal axis ram compactor. The hopper bin/ram compactor unit is interfaced with a large volume refuse transporting container which is removed to a refuse dumping site periodically. The system is capable of on-site operation for extended periods of time with minimal operator attendance. The system assures a substantially trash-free environment.

Abstract: A simplified, safe, fast and economical method of refining gold and a versatile apparatus for practicing the method are disclosed. The process and the apparatus are ideally suited for reclaiming substantially pure gold from gold jewelry and gold alloy scrap. Gold alloy to be refined is inquarted with a non-ferrous metal or metal alloy and the resulting gold alloy is cast into slab anodes which are suspended in an electrolytic cell containing a nitric acid solution as the electrolyte. The cell includes a stainless steel container cathode to retain gold mud or slime precipitated from the slab anode during the electrolytic process. If platinum and/or palladium are present in the gold alloy to be refined, inquartation with silver is carried out, and these platinum metals are dissolved in the electrolyte solution. If iridium or any other platinum metals are present in the gold alloy to be refined, they will remain in the resulting gold mud and subsequent treatment with aqua regia is necessary.

Abstract: A dumping transport vehicle for harvested cotton bolls has the capacity to receive in its basket body two dumps from a large self-propelled harvester. An internal power-operated pivoted packer-divider panel of the vehicle enables compacting of the first dump received from the harvester against the dump-out side of the vehicle basket so that the second dump from the harvester can be adequately received in the vehicle basket. The packer-divider panel also enables a two-stage dumping of the contents of the fully loaded vehicle basket into a module builder which is unable to handle and pack the entire volume of harvested cotton in the vehicle basket in a single delivery or dump.

Abstract: When a child-resistant cap for a container of potentially hazardous contents is turned in either direction of rotation to a release position, cooperative parts on the cap and container will engage and interact to produce a permanent visual indication of tampering.

Abstract: A nephelometer is disclosed which employs immersion optics and conformable optical couplers between components to minimize scattered background light. A multi-compartment micro volume specimen holder employs a cover having integral spacer knees which assure a precision length optical path. The device has the ability to collect small forward-angle scattered light with maximum efficiency and sensitivity. Light pipes are employed to remove a glass-air interface to a remote point where scattering is of much less importance and to act as an axicon for the compact collection of angularly scattered light.

Abstract: A golf club, such as a driver, includes a body portion formed of natural uncompressed hard wood having an angled face on one side thereof. A wedge component formed of laminated highly compressed densified wood is bonded to the angled face of the body portion and forms a striking face and partial bottom face for the club head. Weight is concentrated near the striking face and bottom face to improve club controllability, balance and striking efficiency. Pre-weighing of wood veneers prior to compressing enables control and location of club head center of gravity. Final shaping of the club head is accomplished on a copying lathe.

Abstract: To comfortably and safely restrain the individual occupants of a vehicle, a pair of arm reeceiving, shoulder engaging restraint loops are anchored permanently or removably to opposite sides of each vehicle seat at a proper height to be engaged conveniently by occupants of various sizes. The occupant can slip his or her arms into and out of the restraint loops upon entering and exiting the vehicle with no inconvenience, no disturbing of the clothing and without operating buckles, straps or other fasteners. Coacting restraint hand grips may be provided on each seat in some cases for added safety.

Abstract: To reduce substantially the level of background light which will limit the sensitivity of any photometric measurements and to avoid using optical cements and greases and their inconveniences, optical components as employed in photometric measuring systems are coupled by an optically clear compliant member which is forced into conforming contact with two opposing optical elements. The invention finds application in photometers and densitometers, spectrophotometers, fluorometers and nephelometers. The invention may also be employed in lieu of the usual immersion oil of a high power microscope.

Abstract: A simplified and more economical manufacturing method for the contact head of a spring contact probe is disclosed. Only two passes of a machining tool across the axis of the contact head on orthogonal axes produces a center pyramid contact point, two pairs of surrounding chisel points, and two pairs of contact points in the spaces between the chisel points formed from metal remaining after the two machining passes.

Abstract: A heavy-duty picnic table folds into a compact form for shipment or storage. Two folding end frames which mount a table top and opposite side benches fold in unison when locking pins are removed from two cross braces which maintain the table securely in an erected state. Operational parts are tethered to prevent separation and loss. The table is characterized by strength and stability.

Abstract: Two wide equal length elastic flexible straps are cut on an angle at corresponding ends which are attached to opposite sides of an athletic shoe near the heel region where the shoe sole joins the upper. Each strap on its outer side relative to the shoe has a loop pile fastener component adjacent to the malleolus and on its opposite side adjacent to its free end has a cooperative hook fastener component. The straps in succession are drawn around the rear of the angle and lower leg under elastic tension and across the upper instep and the cooperative fastener components of each strap are pressed together into holding engagement. The two straps cross each other at the rear and front of the ankle and lower leg. A brace is formed which affords the greatest reduction in inversion and eversion of the ankle immediately adjacent to the collateral ligaments of the ankle.

Abstract: A support base for merchandise display racks particularly of the revolving type knocks-down easily for compact shipment and storage without sacrifice of strength and durability when assembled for use. The parts fit together without the need for tools and only a single locking set screw requires tightening. A double telescoping sleeve arrangement imparts strength and stability to the support base. Manufacturing cost is minimal.

Abstract: A mechanically operated, gravity-assisted display device has the capability of being remotely controlled by an unskilled operator to display current numeric pricing indicia for a product or other alpha-numeric indicia for any required purpose. The device is ideally suited for displaying the unit price of gasoline on an elevated sign at a filling station. Multiple gravity-biased sliding panels which are arrayed to form variable indicia are operated remotely by flexible suspension elements equipped individually with fixed enlargements. Interchangeable coded remote operating cards for groups of the flexible suspension elements have passages through which predetermined enlargements may pass while other enlargements are blocked. Movement of the block enlargements with the flexible suspension elements to which they are attached under influence of the coded cards establishes the required change of displayed indicia.

Abstract: To exclude odors, drafts, insects and rodents from the necessary opening in a bathroom floor surrounding the tub drain, an open top dry enclosure box for the tub drain is placed in the floor opening in surrounding relationship to the drain components and includes an upper three-sided narrow suspension flange resting on the top floor surface. The enclosure box is provided in three of its side walls and its bottom wall with knock-out discs to provide a passageway through the enclosure box for either a horizontal or vertical drain pipe downstream from the drain trap, thereby rendering the drain box universal in its application to tub drains.

Abstract: A mechanical foreign object detector upstream from the feed roll of a carding machine faithfully detects minute hard objects in the lap which could damage the lickerin or other components of the card. Spring-loaded detector pins penetrate through the lap and contact foreign objects on an apertured plate beneath the lap. Such pins rise and contact a wire connected in a stop motion circuit which immediately stops the operation of the doffer and the feed roll before any damage can occur. A visual and/or audible indicator alerts the operator to the presence of a foreign object or objects which the operator removes by hand before restarting the card by operation of a key-operated reset switch in the circuit. The mechanical detector apparatus includes a power drive which is synchronized with the operation of the feed roll of the card.

Abstract: A linear air cylinder drives a guided slide block or carriage on which is pivotally mounted a vacuum arm biased by a spring to a down horizontal position. Cam followers carried by crank arms on the pivoted vacuum arm engage fixed stops when the rod of the air cylinder is retracted to swing the vacuum arm to an upright tag pickup position. Tags stored in a hopper are transported one at a time to a horizontal position away from the hopper where they are attached to socks.
