Abstract: An elongated skate blade for an ice skate, the blade including first and second acute-angled cutting edges formed longitudinally on opposed sides of the blade for cutting engagement with an ice surface, and a generally downwardly facing longitudinally extending bottom surface extending transversely from the first cutting edge to the second cutting edge. The bottom surface includes first and second longitudinally extending edge faces rising upwardly and inwardly from the first and second cutting edges respectively, and a longitudinally extending middle face centrally disposed between the first and second edge faces. The middle face has a substantially flat or downwardly convex profile in transverse cross-section for at least one-third of the distance from the transverse center of the blade to each side of the blade.

Abstract: A multiplex security system provides two-way data communications between a local panel and multiple microprocessor-based remote panels interconnected over a common data transmission line. A second line provides two-way voice communications between the local and remote panels with automatic forwarding by an audio/data control selector to a central control unit via a single telephone line. Two additional lines provide a common ground and transmit DC power from the local to the remote panels. The remote panels include bus drivers connected to the communications line for transmitting both ASCII digital data messages and a higher voltage request or SRQ signal to the local panel when the remote panel has a message to transmit. The local panel includes two separate receivers for distinguishing the request signal from digital data and a bus driver for transmitting data. The local panel transmits a grant message which is superimposed over the request signal, reducing its voltage level to zero.

Abstract: A memo or check pad holder is disclosed which is designed to fit into an open shirt pocket and retain not only a memo or check pad but also writing instruments. The holder includes a cover foldable along a flexible hinge into front and back cover sections. The inside face of said one cover section includes means for retaining a memo or check pad. The opposite outer face of the same cover section includes high friction material designed to frictionally engage the inside fabric of an open pocket to resist removal from the pocket. The inside face of the opposite cover section includes parallel spacer ribs extending along the inside face of the other cover section so that when the two cover sections are folded together the spacer ribs define a spacer pocket for receiving writing instruments clipped to a free edge of the same cover section extending generally parallel to the ribs. The ribs also prevent sideways slippage of the writing instruments from the cover section.

Abstract: The specification discloses a forming die or ram movable along a guideway or track by a pair of toggle-joint linkages to move from a column of staples a staple having a downwardly bowed central portion into engagement with an anvil, then bend outer portions down over the anvil to drive pointed legs into the flesh and bring the legs into alignment with each other. The column of staples is pressed by a spring arm and a follower toward the track and is laterally supported in a staple magazine. Each toggle-joint linkage is a one-piece member with two rigid arms connected by an undulating spring portion. The magazine is detachably connected to the track by spring latches or clips. Another stapler has a hook-like anvil, and the bowed central portion of the staple as it is pressed against the anvil by a forming die or ram, is first straightened and then bent legs are bent from the central portion, thus giving a "soft" initial feel to the stapling.

Abstract: A knife and belt buckle case in which the knife is releasably secured to the buckle. The knife includes a blade pivoted to a handle by a pivot pin which has an eccentric head. With the knife open, the eccentric head is positioned for insertion through an aperture of the buckle as the blade is positioned within a blade receiving recess of the buckle. When the knife is closed, the inserted eccentric head engages the back surface of the buckle and releasably secures the knife to the buckle. The blade is threadably mounted to the pivot pin so that, as the knife is opened, the blade moves into frictional engagement with the handle and holds the knife open. Also, as the knife is closed, the blade moves toward the eccentric head and clamps a portion of the buckle between the head and blade to thereby tightly secure the knife to the case. A detent couples the handle to the buckle and prevents undesired opening of the handle.

Abstract: A high kinetic energy water spraying apparatus wets powdered or granular dry material, particularly hard-to-wet polymers, to provide a lump-free solution of a controlled concentration. A volumetric feeder drops the dry material through a fructoconical upper portion of the apparatus. Water is injected tangentially so that the inner surface of the upper portion is completely wetted to prevent buildup of dry material on the surface.A lower portion of the apparatus comprises a cylindrical column which receives dry material from the upper portion. The inner surface of the column includes a series of spray nozzles positioned to produce downwardly sloped and radially inwardly oriented jets of liquid which impinge falling dry material with high energy. The downward slope of the jets creates a downward air flow so that any dust from the dry material is drawn downwardly into the column.

Abstract: A moisture measuring apparatus includes a tuned circuit, a moisture sensor, coaxial cable means between the sensor and the tuned circuit wherein the tuned circuit tunes the coaxial cable, and a circuit for ascertaining the loading presented by the sensor to the tuned circuit whereby moisture is measured. The sensor is alternately connected and disconnected to an end of the coaxial cable and the signal drive across the tuned circuit is standardized by a controlled gate circuit which adjustably clips the tuned circuit drive, when the sensor is disconnected, for zeroing the instrument. Also, the gain of the circuitry is adjusted by periodically providing a standard load to the tuned circuit while adjusting amplification to bring about a standard output. The apparatus is not as sensitive to cable changes as prior apparatus and a plurality of selectable coaxial cables are provided on reels adjacent the sensor console.

Abstract: A veneer lathe charger apparatus is disclosed for scanning a rotating log with light to determine its optimum yield axis and adjusting the charger spindles through a greater range necessary for large diameter logs to position such axis at a predetermined transfer position. The log is rough centered with its longitudinal axis at a scanning position by rough centering arms which are released prior to scanning. After scanning the log is moved from its scanning position to align such optimum yield axis with a predetermined transfer position axis where it is engaged by a transfer clamp means for movement to a lathe axis position without reclamping by such centering arms. A spindle support and adjustment means is provided for adjusting the charger spindles to move the optimum yield axis of the log to the transfer position axis. A control means enables directionally limited adjustment of the charger spindles a greater distance away from the transfer clamp means than toward such clamp means.

Abstract: A substantially entirely plastic rotary drum filter is made by applying a layer of plastic to the interior surface of a cylindrical mold, removing the mold, and applying at least one additional layer of plastic to the exposed exterior surface of the shell formed by the first layer. A plastic annular axial valve housing with plural valve chambers and a central valve receiving space is mounted to a head assembly at the head end of the shell. A tail assembly closes the opposite end of the shell to form the drum. Circumferentially spaced interior plastic bucket sections are positioned midway between the head and tail assemblies. Upon the periodic application of a vacuum to the valve chambers, filtrate is delivered from the exterior of the drum through an associated bucket and plastic drainage conduit to an associated valve chamber. Plastic reinforcing rings strengthen the drum along its length and in the region of the bucket section.

Abstract: A method for growing acid producing bacteria in the presence of an essentially water insoluble or a temporarily water insolubilized and thus initially solid form of a neutralizing agent in a growth medium is described. The water insoluble or insolubilized neutralizing agent is a base, basic salt or mixture thereof adapted to provide a controlled reaction with the acid produced by the bacteria without substantially raising the pH of the growth medium. Preferably the neutralizing agent is in a water insoluble form. Bulk starter compositions for growing the bacteria including the insoluble or the insolubilized neutralizing agent are also described. Further, bacterial compositions with enhanced storability and viability because of the insoluble or the insolubilized neutralizing agent are described. The method and bulk starter compositions are particularly adapted to growing lactic acid producing bacteria which are then used in making food and beverage products for animals and humans.

Abstract: A rock crusher includes a dual cam shaft drive mechanism for imparting substantially linear motion to a movable jaw between a pair of fixed jaws. A driven cam shaft coupled to the movable jaw cooperates with another cam shaft also coupled to the jaw to impart this motion to the jaw. In one embodiment, the maximum eccentricity of the driven cam shaft is less than the maximum eccentricity of the other cam shaft so that the other cam shaft oscillates and imparts the desired motion to the movable jaw. In another embodiment, the cam shafts have the same maximum eccentricity and are synchronized to move together, such as by gears, during crushing.

Abstract: A chain saw is provided with a saw chain cassette and a releasable clamping cover for holding the cassette against the side of the chain saw frame. The clamping cover, together with the cassette and the chain saw frame, have aligning surfaces extending in a direction longitudinal of the cassette saw bar for preventing relative rotation between the saw bar and the frame. A tightening mechanism for the cassette is used for urging the saw bar forwardly with respect to its drive sprocket and a further mechanism is provided within the cassette comprising a spring biased shoe for urging the cassette sprocket in a direction for tightening the chain when the cassette is removed from the chain saw frame. A camming device on the frame engages the shoe when the cassette is installed on the frame for holding the shoe away from the sprocket such that the latter can be driven by the chain saw motor drive shaft.

Abstract: An emergency shutdown device for an internal combustion engine, especially a fuel-injected diesel engine. In addition to shutting off the flow of fuel to the engine, the device "suspends" fuel within the engine fuel supply system to prevent it from passing into the engine combustion chambers. The device provides a controllable vacuum means which, by preventing fuel passage into the fuel injector pumps, quickly "starves" the engine of its fuel supply.
