Title: Variable speed bicycle automatic torque converter transmission
Inventor: STUHLER WILLIAM B
IPC: B62M9/08
Filed: 1991-08-19
Granted: 2002-04-02
Abstract: A fully automatic torque converter transmission is presented that uses a "V" belt with inner teeth that engage mating teeth on a variable pitch pulley core in a low speed high torque state transformable into an infinitely variable higher speed shift mechanism. The bicycle pedal sprocket drives a pivoted cluster of three small sprockets with a drive chain loop interconnect driving a first sprocket as a driven member, and the other two serving as idlers in maintaining the chain at constant length. A speed ratio of approximately 1:6 from the pedal sprocket to the driven sprocket optimizes torque transmission capacity of the system with the driven sprocket attached to a self-centering, spring loaded, variable pitch pulley. This pulley has a core shaped like a timing belt pulley with grooves (or teeth) at its surface. The "V" belt driven by the variable pitch pulley drives a timing belt type pulley that rotates on a center fixed relative to the bicycle frame, and is a "Y" belt with teeth on its inner surface enabling engagement with the variable pitch pulley core at the low speed high torque position. This converts the friction "V" belt drive to a positive drive in low gear.      The driven pulley, finally, drives the rear wheel through a conventional bicycle chain.

Title: Fluid applicator for animals having a metering dispensing valve
Inventor: LAURENZ FRANK R
IPC: A01K13/00
Filed: 1992-03-18
Granted: 1994-07-05
Abstract: A dispensing device  for applying liquids such as pesticides  to the coat  of an animal comprises an elongate rope mounted at an upper end on a bracket and at a lower end position spaced from the bracket outwardly to one side to allow the animal to pass under the rope and to rub its back on the rope.   The bracket includes a valve operable by the upward  force  from the rope to dispense a measured dose of liquid onto the rope to impregnate the rope for applying the liquid to the animal's coat.

Title: Coating composition and methods of use
Inventor: VAN WINCKEL WALTER
IPC: B05D1/32
Filed: 1991-07-23
Granted: 2007-04-10
Abstract: A differential adhesion coating composition (DAC) is provided herein. Such DAC composition is first applied to trim material which is to be subsequently painted without regard to covering adjacent glass. The DAC composition is characterized by high adhesion to wood, metal, plastics and painted surfaces and at the same time by selective low adhesion to glass surfaces. After the painting operation of the window frame is completed, the dried DAC composition may be easily scraped, peeled, or otherwise lifted from the glass, together with any paint overlay thereon. When subjected to shear forces of pulling and scraping, the cohesive properties of the DAC composition, when considered in combination with a relatively low adhesion to glass, allows the dried DAC  composition, to be removed in long continuous strips rather than fracturing into small pieces.  Also, the DAC can be used directly as a paint, so that any paint which is inadvertently applied to glass during a painting operation can be subsequently lifted off the glass.

Abstract: A method for supplying gas to gas consumers, which method resides in forming a storage reservoir above a gas-saturated water-bearing horizon under development, filling the storage reservoir thus-formed with gas by periodically subjecting the horizon under development to extraneous effects, followed by delivering the gas to gas consumers. Extraneous effects can be exerted by generating elastic vibrations, providing a pressure difference, rising the temperature, applying electromag-netic field oscillations, or combining these factors. If the method of the invention is used in seismically active areas or in regions exposed to effects of elastic vibrations, its efficiency is considerably increased.

Title: Peripheral arterial monitoring instruments
Inventor: APPLE HOWARD P
IPC: A61B5/022
Filed: 1994-05-02
Granted: 2005-02-15
Abstract: A method and apparatus are described for determining characteristics of peripheral arterial volume and compliance. A blood pressure cuff is inflated and deflated around a limb of the body and pressure measurements are taken. The volume of air removed from the cuff is determined in a quantifiable manner, such as by expelling air through an orifice of known characteristics or by means of a volume of know characteristics. The detected pressures and volume of air removed are used to compute oscillation volume, which in turn is used to display arterial capacity and compliance as a function of transmural pressure and time. Arterial capacity may be displayed in terms of arterial radius, arterial cross-sectional area, or arterial volume. Also, systolic and pulse pressures are determined using only these determined values.

Abstract: A cross laminate of two films, each of which is uniaxially or unbalanced biaxially oriented, the films being arranged so that the major axes of orientation criss-cross each other (steps 1 to 3), is treated in a calendering process in which machine direc-tion ribs are formed which are thicker than the sheet between the ribs and which have a configuration which confers increased re-sistance to bending over a line perpendicular to the rib. The ribs are formed by a combination of passage between grooved rollers ("lateral calendering") (steps 4 and 6), the grooves of which include inclined walls on opposing grooves between which the mate-rial of the laminate is squeezed, longitudinal stretching (step 5) and heat treatment (step 10). In a preferred process a sandwich of two cross-laminates is subjected sequentially to passage between a first set of grooved rollers (step 4), longitudinal stretching (step 5) and passage through a second set of grooved rollers (step 6) in which the undulations created in the first set of rollers are regis-tered with the second set of grooved rollers, followed by heat treatment (step 10), for instance an ironing process. The cross sand-wich is then cooled (step 11) and separated into two cross laminates (step 12).
