Abstract: Multi-layered optical data records and playback apparatus are described in which a plurality of optical data layers are provided on at least one side of a record substrate and the playback apparatus scans data tracks on such layers with a light beam to produce an electrical readout signal corresponding to the data in the scanned tracks. The playback apparatus includes selection means for selectively playing back data tracks on different ones of the data layers. The data track may be formed by lines of data spots of binary coded digital information or such spots may be frequency modulated or pulse length modulated analog information which are photographically recorded at extremely high data density so that they may be used to record audio or video signals including television signals.

Abstract: An adaptor collar which can be joined to a standard laboratory jar for the purpose of maintaining a constant anaerobic atmosphere inside of the jar is disclosed. The combined adaptor collar and jar form a transport unit suitable for the transport of anaerobes from remote locations to a controlled atmosphere incubation apparatus. The adaptor collar is adapted to dock with the incubation apparatus so that anaerobes can be transferred from the jar to the interior of the apparatus without exposure to the air.

Abstract: The specification discloses an embosser in which diecast aluminum embossing segments are adhered by epoxy to a roll in rows along long spirals. The roll is driven, and is adjustable toward or away from a resilient backing roll, and co-acts therewith to emboss a web advanced therebetween.

Abstract: An apparatus for cooking eggs is described in which the control of cooking is based upon indirect measurement of viscosity of the contents of one of the eggs being cooked. Viscosity is measured by oscillating the egg in rotation at a frequency determined by the spring constant of the system and at a constant torque while measuring the amplitude of oscillation. When, due to cooking, the amplitude of oscillation, which is a function of the viscosity of the egg contents, increases to a preset threshold, cooking is automatically terminated.

Abstract: An impact pulverizer mounts a rotor concentrically within an octagonal shaped reduction chamber. The rotor has a substantially solid core and generally radially extending impact blades, each of which slopes in the axial direction of the rotor. Upon rotation of the rotor, the blades strike pulverizable material and propel the same radially of the chamber and against the interior walls thereof. The slope of the blades moves the pieces longitudinally of the chamber from the intake toward the egress end in a generally spiral rotational motion as the pieces ricochet off the interior walls and back against the rotor blades, striking each other as they so progress. The striking and ricocheting cause the pieces to break up and be reduced in size as they travel towards an outfeed opening.

Abstract: A record and playback system for reducing repetition redundancy is described in which during recording, a partially repetitive signal, such as a television signal, is converted into digital data words each representing the signal occurring during a particular TV line subinterval. A comparator unit receives the data words and compares each received word with a word from a recirculating storage that corresponds to the same line subinterval in its frame as that of the compared received data word. When the compared words differ by a predetermined value, the received word replaces the stored word in the storage and is also stored in a changed data memory as an updated data word along with address words. A recording control circuit intermittently causes the read out of data from the changed data memory for recording at selected positions of a data record.

Abstract: A rigid building component such as a door, table top or the like, is formed of coarse wooden particles mixed with adhesive, and a solid wooden edge frame, positioned between a pair of damp, substantially parallel, cellulosic fiber webs. A heated press is employed to compact the combination, particularly between the edge frame and the cellulosic fiber webs where the coarse wooden particles are greatly compressed to provide a durable edge. Under the heat and pressure applied in the press the particles are consolidated into a solid structure, while the damp cellulosic fiber webs are converted to tough exterior skins bonded to the coarse wooden particles. The sides of the rigid building component are suitably deeply embossed to provide a decorative paneled appearance.

Abstract: A counterflow heat exchanger is described with two sets of heat exchanger passages separated by heat exchanger plates disposed in substantial parallelism within the exchanger and supported so that the passages extend substantially vertically. The heat exchanger may be employed as an air-to-air or as an air-to-water heat exchanger and can be used to remove moisture or pollutants from hot exhaust air by condensation within the exchanger passages. When employed as an air-to-water heat exchanger, the water is sprayed onto the surfaces of the upper ends of one set of passages so that it flows down their length, while air is transmitted into the lower end of the other set of passages and caused to flow upward.

Abstract: The specification discloses a torque coupling having two tubular coupling members having flanges with interlocking teeth wedged together by a clamping ring. The flanges have opposed grooves in which are positioned elastomer sealing rings having shallow grooves with sharp edges forming vacuum seals with the bottoms of the grooves in the flanges, the rings being pressed together.

Abstract: A club container is removably mounted on a cart and has a bottom notch receiving a crossrod of the cart and an upper, releasable latch. The club container has a pleated, flexible plastic irons separator and has long tubular sockets receiving shafts of the woods. The cart has a frame of two U-shaped tubes secured together by rivets which also pivot a U-shaped wheel suspension tube carrying pivot pins on which are pvioted circle-carrying arms biased by torsion spring rods secured to the tube. To form a folding linkage, a pair of rods having bent-over lower end portions trapped in the wheel suspension tube are held together with bent-over, upper end portions trapped in a block secured to a handle. Two pairs of legs pivotally secured to a seat and having ends hooked into the frame of the cart mount the seat, along with a pair of braces hooked into the frame and slidable along one of the pairs of rods, for overcenter movement between a seating position and a folded position.

Abstract: A vertical antenna comprises a substantially vertical conductor supported on an insulating rod and wound tightly at the top to provide a top loading coil. A capacitive plate is conductively attached to the antenna conductor between the top loading coil, and a connecting adapter located at the lower end of the insulating rod and to which the antenna conductor is joined. An additional radiating coil is wound over the lower portion of the antenna, including the capacitive plate, while being insulated therefrom.

Abstract: An improved clam shovel for digging razor clams includes a dished shovel blade attached to the lower end of a shovel shaft having a handle at its opposite end. The upper side of the shovel blade is transversely and longitudinally concave. The blade is longitudinally slotted inwardly from the center of its free cutting edge to about mid-length to define a pair of broad laterally spaced tines. The slot tapers inwardly from the blade cutting edge so that its inner closed end is narrower than its outer open end and so that the slot resembles a wedge blocked off and rounded at its narrow end.

Abstract: A vigorous well-branched upright plant of the hybrid tea class, having long-lasting flowers of a non-blueing red color, with very strong resistance to Rose Powdery Mildew and slight fragrance.

Abstract: A vigorous rose plant of the floribunda class, characterized particularly by its pointed flower bud and petal formation, its high resistance to rose powdery mildew, with continuous flowering blooms with little or no fragrance.

Abstract: A vehicle conveyor suitable for a car wash is described wherein tire-engaging rollers are attached to a continuous chain positioned underneath the path of the vehicle. The rollers are normally carried by the chain in a nonengaging position below the vehicle track. Then, when movement of the vehicle is desired, a coin-actuated control or a manual control is actuated to move a cam into operative position to cam one of the rollers upwardly through a slot onto the top surface of the vehicle track where it engages the vehicle's tire. The roller subsequently drops through a slot proximate the end of the conveyor course.
