Title: Modified cylinder head
Inventor: CLARKE JOHN MICHAEL
IPC: F02F1/42
Filed: 1991-08-30
Abstract: Multiple intake valves operatively associated in a common combustion chamber are advantageous in that the design achieves high output for an internal combustion engine. The subject modified cylinder head utilizes the advantages available in a multiple intake valve system, but further enhances the design by reducing heat rejection. In the subject modified cylinder head, three intake valves (38, 40, 42) having corresponding intake valve ports (26, 28, 30) and one exhaust valve (68) having an exhaust valve port (66) are operatively associated in a common combustion chamber. A  reduction in heat rejection is achieved through a relationship between the cross-sectional areas of the intake and exhaust valve ports (26, 28, 30, 66). The intake valve ports (26, 28, 30) are constructed so that their cross-sectional area is larger than about 69 %  of the combined cross-sectional area of the intake and the exhaust ports (26, 28, 30, 66).

Abstract: A belt clutch control apparatus is disclosed having a control handle and linkage means for selectively controlling the transmission and power from a driving pulley to a driven pulley through a driving belt. In a preferred embodiment, the apparatus is specially adapted to control the operation of the cutting blades on a riding mower. The linkage includes an undercenter connecting link for transmitting rotational movement of the control shaft to a bellcrank, which engages a tension spring to operatively move an idler pulley between engaged and disengaged positions relative to the driving belt. The undercenter link moves exclusively between first and second undercenter positions, and is never forced into an overcenter position. An assist spring is provided for securing the undercenter link in both its on an doff undercenter positions, thereby relieving the idler pulley spring for this purpose. The linkage significantly reduces both the travel and effort required to move the control handle between its on and off positions.

Title: Bottle stress analysis system
Inventor: GOOCH JAN W
IPC: G01L1/24
Filed: 1993-08-26
Abstract: ABSTRACT A bottle stress analysis system using polarized light for determining stress levels of a transparent plastic bottle includes a rotation assembly for rotating the bottle.  A polarized light source assembly is insertible into the bottle cavity to direct plane polarized light through the bottle wall and an analyzer assembly is positioned outside the bottle for measuring intensity of light passing through the bottle wall.  In order to measure changes in polarization, the analyzer assembly has a polarization analyzer positioned to transmit the light to a photodetector. A mechanism for rotating either the polarized light source or the analyzer to determine maximum and minimum polarized light intensity at the photodetector facilitates determination of stress at a plurality of points along the bottle wall.  A computer controlled analysis of the polarized light intensity can be used to produce a stress profile of the bottle, permitting rejection of bottles having abnormal internal stress that are likely to fail under internal pressure loading.

Title: Method for production of gas hydrates for transportation and storage
Inventor: GUDMUNDSSON JON S
IPC: F17C11/00
Filed: 1991-07-08
Abstract: Method for the production of gas hydrates for storage and transportation of hydrate forming gases, The gas is pressurized and cooled, whereupon the gas (1b) is supplied to a vessel (6), to which water (7) is added simultaneously to the vessel (6) to foam fine water droplets that are dispersed in the gas (1b) supplied. The temperature and pressure in the vessel (6) are adjusted to pro-duct hydrate from water and gas. The gas (1b) supplied and the water droplets (7) react to form hydrate (8a); then the hydrate is then withdrawn from the reactor (6), optionally cooled in a cooling apparatus (11), and then passed to an agglomeration step (12) to agglomerate the hydrate (8a), thus increasing the density of the hydrate (8a) and to embed more gas in the interstices between the hydrate particles (8a). The agglomerated hydrate particles (8a) are transported to a suitable transportation unit or storage con-tainer to transport/store the hydrate at adiabatic conditions at atmosphere pressure or at a slight gauge pressure at a temperature below 0°C, preferably at minus 10°C to minus 15°C.

Patent CA-2123960-A1 (CA)
Inventor: SEVILLA ERNESTO G
IPC: A61B18/12
Filed: 1994-05-19
Abstract: A current sensing device enables sensing the current being delivered from a source to a load at a medical implement connected to the distal end of a primary conductor connected between the source and the load in situations wherein distributed capacitance between the primary conductor and a return path to the source prevents a measurement of current at the source end of the primary conductor from being an accurate measurement of the delivered current. The current sensing device includes a reference conductor which is located beside and is preferably twisted together with the primary conductor along the length thereof and which is connected to the medical implement load through a resistor at the load of a value such as to effectively electrically isolate the reference conductor from the load. A subtractor subtracts the current flowing through the reference conductor from the total load current flowing to the medical implement so as to offset the effect of the distributed capacitance and to thereby produce a current measurement corresponding to the delivered current. The subtractor can comprise a current transformer through which the conductors extend in opposing relation.      An integrity detector monitors whether the reference conductor is intact.

Abstract: A carrier containing a plurality of layers of articles, such as beverage cans, arranged in stacked end-to-end fashion. The carrier(10) is fully enclosed and is formed with overlapping top panel flaps (16, 18) which produce an area of double thickness between handle openings in the flaps. A reinforcing sheet (40) on the underside of the top panel in the double layer area protects against tearing while stress relief lines (34, 36) in the form of score lines extending from the ends of the handle opening to the corners of the carrier (10) provide for distribution of lifting and carrying stresses. A separator sheet (70) preventing direct contact between stacked articles extends between layers and may include distortable areas (72) aligned with the articles. Downward pressure on the upper layer (C1) causes the bottom of an article to force the distortable area into a recess in the top of the next lower article.

Title: Process for Preparing an Amorphous, Extra-Hard Material Based on Boron Nitride
Inventor: WILDENBURG JOERG
IPC: C03C3/32
Filed: 1993-02-09
Abstract: A process is disclosed for preparing an amorphous ultra-hard material based on boron nitride that is sufficiently hard to scratch diamond. Hexagonal or turbostratic boron nitride hBN is compressed under pressures of at least 70kbar or more and heated up to temperatures of at least 1650°C or more until a molten mass of boron nitride is obtained. The thus formed molten mass of boron nitride is quenched by stopping heat supply, then the pressure on the quenched molten mass of boron nitride is relieved. The hexagonal or turbostratic boron nitride used as feedstock is treated in the presence of crystallisation inhibitors, so that no crystals are formed and the amorphous crystalline structure is condensed by deposition of reaction products such as boron suboxides.
