Title: Synthesis gas preparation and catalyst therefor
Inventor: GOETSCH DUANE A
IPC: C01B3/40
Filed: 1990-04-19
Granted: 1999-10-05
Abstract: Synthesis gas is produced by the reaction of light hydrocarbons, primarily methane, in a fluid bed reaction zone of attrition resistant nickel on alpha-alumina catalyst, with steam and oxygen and the conversion level is preserved by limiting the loss of nickel from the reaction and thereby limiting the back reaction of the synthesis gas to form methane in the presence of entrained catalyst in a cooling zone.

Title: Stand-up sign holder
Inventor: FAST JACOB
IPC: G09F1/14
Filed: 1990-03-22
Granted: 1995-01-17
Abstract: ABSTRACT OF THE DISCLOSURE          A stand-up label or sign holder for use in supermarkets  or  bakeries  is  made  of  plastic  sheet material and has a base panel at one end, a label or sign holder panel at its opposite end and an elongate stem connecting the panels.   The base panel can be used to support the holder by folding the base panel at right angles to the stem so that the holder stands on the base panel with the stem extending upwardly toward the holder panel.  The holder panel can be bent back toward the base panel to stabilize the holder.   Also,  the stem has lengthwise ribbing which promotes transverse bowing of the stem so as to resist lengthwise twisting or bending. The label or sign holder panel has tabs for retaining a sign or label.   If the holder is made of transparent plastic, the sign or label is visible from both aides of the holder panel.

Title: Containers
Inventor: ANDREW REX
IPC: B65D77/04
Filed: 1991-01-28
Granted: 1996-10-22
Abstract: Containers have an outline in underneath plan view which is wedge shaped.  The wedge has a length greater than its width at the thicker end.          The containers are packed on a rectangular floor area, which may be the base of a box, with at least some containers in pairs side by side touching each other but with their wedge shapes oriented oppositely so that the thinner end of each wedge shape is adjacent the thicker end of the wedge shape of the other container of the said pair, but with a gap between the thinner end of each wedge shape and a notional rectangle whose sides are parallel to or coincide with sides of the rectangular boundary, and which fits around the wedge shapes with one pair of sides contacting the non-touching sides of the wedge shapes and the other pair of sides contacting the thicker ends of the wedge shapes.          This gives flexibility in fitting the containers onto a floor area, and in turn gives greater freedom of choice when designing packaging for a product.

Abstract: A method of filtering beverages and other liquids. To avoid the considerable ecoproblems encountered with the filter aids of known procedures, which must be thrown away, the filtering active structure of the inventive filter aids is maintained so that they may be reused as often as required. A mixture of filter aids of varying morphological and physical components is used, and constitutes a minimum of two components, namely one component of specifically heavy, chemically stable metal and/or metal oxide and/or carbon particles of fibrous and/or granular structure, and a further component, for building up the filter cake and increasing its volume, of synthetic and/or cellulose fibers having a fiber length of 1 to 5000 µm and a fiber thickness of 0.5 to 100 µm. To increase the filtering efficiency of the filter cake of the aforementioned components, a further component may be added that comprises fibrillated or fanned out synthetic and/or cellulose fibers, preferably having a fiber length of 500 to 5000 um and a fiber thickness of 0.5 to 20 µm. The components are intensively mixed to form a homogeneous mixture, and are dosed to the liquid that is to be filtered.

Title: Quick-release clipless pedal
Inventor: CHEN CHUNG-I
IPC: B62M3/08
Filed: 1992-05-01
Granted: 1995-03-14
Abstract: A quick-release clipless pedal includes a cleat, which is to be fixed to a shoe sole and which has first and second engaging parts respectively formed on front and rear ends thereof, and a pedal body, which is to be mounted on a pedal shaft and which has a claw portion to receive releasably the first engaging part of the cleat and a pair of retaining units revertably engaging the second engaging part of the cleat. Each of the retaining units is disposed in one of the receiving grooves formed in a rear end of the pedal body and includes a rear jaw pivoted onto the pedal body and biased so as to engage the second engaging part of the cleat. Application of a lateral upward thrust on the cleat causes the first engaging part to disengage from the claw portion and further causes the cleat to push the rear jaw of the respective retaining units rearward, thereby causing the rear jaw to pivot in order to allow a lateral disengagement of the cleat from the pedal body.

Patent CA-2098216-C (CA)
Inventor: MAEDA SHIGEMI
IPC: G11B7/005
Filed: 1993-06-11
Granted: 1996-07-16
Abstract: An information reproducing apparatus has: (1) a reference signal generating circuit for generating a first reference signal corresponding to a reproduced signal of main information; (2) a first switching circuit for selecting one of the reproduced signal and the first reference signal; and (3) a controller. The controller, which generates a selection-instructing signal, selects the reproduced signal during reproducing of the main information recorded area, and selects the first reference signal during reproducing of the main information unrecorded area. With this arrangement, when the main information unrecorded area is reproduced, the clock for carrying out the reproducing of main information is synchronized with the first reference signal, which corresponds to the reproduced signal. Thus, when the reproducing area is changed from the main information unrecorded area to the main information recorded area, the synchronizing with the reproduced signal is carried out quickly, thereby improving the reliability of the reproducing process.

Abstract: A magnetic actuator for adjusting the zero and span settings of a transmitter used in industrial process control systems.  The actuator has a single magnet in a housing. The actuator is removable from the transmitter.     When the actuator is unactuated the magnet is in a null position wherein it does not actuate either the zero or span setting reed switches.  The magnet can be moved to either a first position wherein it actuates the zero setting reed switch or a second position wherein it actuates the span setting reed switch.  The actuator applies a torque in the proper direction to return the magnet to the null position when the torque applied to move the magnet to either the first or second position is removed.
