Title: Process and reactor for the preparation of a gas which is rich in hydrogen and/or carbon monoxide
Inventor: PRIMDAHL IVAR IVARSEN
IPC: B01J19/26
Filed: 1993-08-12
Granted: 2000-04-25
Abstract: A process is provided herein for the preparation of a gas which is rich in hydrogen and/or carbon monoxide. The process includes the partial oxidation of a hydrocarbon feedstock in a reactor with an upper portion, a lower portion, and a refractory lining which is attached to an inner surface of the reactor. The process includes the first step of introducing the feedstock and an oxygen-containing gaseous atmosphere into the upper portion of the reactor. That feedstock is then partially oxidized with oxygen in the upper portion of the reactor. A part of that partially-oxidized feedstock is then contacted with a reforming catalyst which is arranged on the refractory lining in at least the upper portion of the reactor. In this way, the lining is cooled by endothermic reforming reactions proceeding in the partially-oxidized gas on the refractory lining.

Abstract: An improved folder apparatus includes a first folder assembly which forms a first fold in sheet material along the path of movement of the sheet material.  A second folder assembly forms a second fold in the sheet material in a direction extending transversely to the path of movement of the sheet material. A third folder assembly forms a third fold in the sheet material with the first and third folds extending along the path of movement of the sheet material through the third folder assembly and the second fold at a leading edge portion of the sheet material.  During the forming of the three folds, the sheet material is continuously moved through the folder assemblies without stopping.  The third folder assembly includes an array of upper and lower tapes.  The array of tapes tapers from a wide inlet portion of the third folder assembly toward a discharge portion of a third folder assembly.  The array of upper and lower tapes maintains areas on opposite sides of the third fold flat in a horizontal plane while the sheet material is gripped by the tapes.  A stacker assembly stacks the folded signatures received from the third folder assembly in a stack with major side surface areas in an upright orientation and with the third fold downward against a supporting surface.

Granted: 2004-08-31
Abstract: A reservoir (3) is connected to a manually operable pump such as an aspirating syringe (1) via a flow control tube (4) which has a fine bore of accurately known size. Actuation of the syringe (1) by the patient discharges a fixed volume of drug via a non-return valve (5) to the patient. The syringe (1) is refilled by a return spring (2) drawing liquid from the reservoir (3) at a rate controlled by the bore of the flow control tube (4), thus silting a maximum dosage rate.

Title: Ground fault circuit interrupter incorporating miswiring prevention circuitry
Inventor: NEIGER BENJAMIN
IPC: H01H47/22
Filed: 1994-07-04
Granted: 2007-06-26
Abstract: A ground fault circuit interrupter (GFCI) with built in intelligence is described that includes circuitry to automatically indicate a device miswiring condition. When a GFCI is wired with its AC and LOAD terminals reversed, downstream devices are still protected in the event of a ground fault but the duplex receptacle on the GFCI  itself is not. The invention incorporates miswiring sense circuitry that automatically triggers the generation of visual and audible alarms in the event a miswiring condition is sensed. The invention employs an alarm inhibiting technique that incorporates sense circuitry connected to the AC terminals on one side of the internal GFCI  switches or relays and alarm generation circuitry connected to the LOAD terminals on the opposite side.

Patent CA-2136460-C (CA)
Title: Viscous material dispenser and method for dispensing
Inventor: TOPPER ROBERT T
IPC: B67D1/10
Filed: 1994-11-23
Granted: 1999-01-19
Abstract: A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container.  When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder.  The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston begins to move in the second direction through the material. Suctioning the material from the collapsible container, as opposed to compressing the container to expel the material, is preferable when the material contains entrapped gas, as is the case with ice cream, since repeated compression of such containerized material can diminish its quality.

Abstract: Wet strength resins for paper are prepared by a process comprising the following steps in sequence:  (1) reacting a polyamidoamine with an epihalohydrin until the amount of unreacted epihalohydrin present is less than about 10% by weight of the amount of epihalohydrin charged,  (2) adding a water-soluble, nonpolymeric amine in an amount of about 0.1 to about 50 mole %, based on the amine in the polyamidoamine, and (3) heating to effect crosslinking.  An optional amine additive reaction step can be included after step (2).  A nonhalogen acid such as sulfuric acid can be added toward the end of the crosslinking step to decrease the total organic halogen content and increase the wet strengthening effectiveness.

Title: Cycle, tensioned spoked wheel assembly and hub therefor
Inventor: DIETRICH ROLF
IPC: B60B27/02
Filed: 1996-10-11
Granted: 2005-09-06
Abstract: Improvements in rear bicycle wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to the multiple sprockets and the distal spokes which are opposite from the sprockets. In one embodiment, torque balancing is achieved by providing the hub with a distal hub flange which has a diameter which is substantially larger than the proximal hub flange. Excellent results have been achieved in a wheel with a hub having a proximal hub flange with a diameter of X and a distal hub flange with a diameter of approximately 1.5 X. According to another embodiment, a wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission tasks to the distal spokes which, as noted above, are under less tension than proximal spokes under static conditions. In yet another embodiment, a wheel according to the invention includes a novel hub in which torque is transmitted to the hub at a point between the distal and proximal hub flanges, but closer to the distal hub flanges.

Une partie proximale longitudinale du corps présente une pluralité de cannelures (32) transversales par rapport à la longueur dudit corps, et espacées les unes des autres par des nervures (30). Le diamètre de la cheville au niveau de la cannelure la plus proche de la tête est inférieur à son diamètre au niveau des cannelures les plus éloignées dans le sens distal. En conséquence, la force de cisaillement est transférée à la cannelure la plus proche dans le sens proximal, et, lorsque cette force dépasse une ampleur prédéterminée, la cheville (12) se brise au niveau de la jonction entre le corps et la tête.
