Title: Packaging film and packaging of detergent compositions therewith
Inventor: HAQ ZIA
IPC: C08J7/043
Filed: 1982-11-10
Granted: 1988-03-10
Abstract: A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency. The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other. It may be used, with the protected side innermost, for unit packaging of detergent compositions, especially liquids containing bleach. In use in the washing machine, the unprotected surface is attacked by the wash liquor to release the contents; the protective layer prevents attack of the package by the contents during storage.

IPC: B24B23/00
Filed: 1983-09-29
Granted: 1988-02-11
Abstract: A clutch assembly for a sanding head is disclosed, the assembly giving a sanding head the dual functions of orbital sanding or rotary grinding. The assembly incorporates a clutch plate and actuating means between an eccentric drive head and backup pad secured thereto.

Title: Improvements in radial piston engines
Inventor: MORRISON RONALD D
IPC: F02B57/10
Filed: 1984-12-03
Granted: 1989-03-02
Abstract: An internal combustion engine combines the efficiency of a radial engine with the practicality of a piston and crankshaft arrangement. A stationary frame supports a stationary sun gear, and a rotor is pivoted about the axis of the sun gear. The rotor carries three crankshafts at 120° intervals, each having an eccentric portion. For each crankshaft there is a cylinder in the rotor, a piston mounted for reciprocation in each cylinder, and a connecting rod from the piston to the eccentric portion of the corresponding crankshaft. Each crankshaft is fixed to rotate with a respective planetary gear, and all the planetary gears mesh with the sun gear and have the same pitch diameter as the sun gear, so that any point on the pitch circle of a planetary gear describes a cardioid as the planetary gear rotates around the sun gear once. The crankshaft eccentricity is substantially 1/3 times the pitch radius of a planetary gear. The eccentric portion of each crankshaft has roller means rotatable about the same axis as the connection between the connecting rod and the eccentric portion, and a ring member with an internal surface surrounds and contacts all of the roller means simultaneously, the ring member being free to rotate about its own axis. Fuel metering means provide a combustible mixture for the cylinders, and ignition means are provided to ignite the combustible mixture in each cylinder. Three valves admit the combustible mixture to each cylinder, each valve having a valve shaft and a valve head at one end of the shaft. The shaft reciprocates in a bore of the rotor, the bore being substantially radially arranged with respect to the rotor axis. The shaft has at its end remote from the valve head a roller adapted to contact the inernal surface of the ring member over a fraction of each rotor revolution, thereby to depress the valve for the admission of the combustible mixture. Porting means are provided for exhausting products of combustion from each cylinder.

Abstract: A reflection phase shifter connectable to a waveguide for shifting the phase of a high frequency signal received from the waveguide. The phase shifter includes a waveguide section having two pairs of opposite side walls and an end wall forming a short-circuit. The side walls define a cavity and an opening opposite to the end wall for communication with the waveguide. The waveguide section has a broad dimension between one pair of opposite side walls corresponding to the width dimension of the waveguide and a narrow dimension between the other pair of opposite side walls which is smaller than the height dimension of the waveguide. A switchable semiconductor arrangement, including a switching semiconductor element and a housing for accommodating the switching semiconductor element, is adjustably mounted in a side wall of the waveguide section and penetrates into the said cavity with a controllable penetration depth for tuning said waveguide section for a desired phase angle shift. A tuning pin is mounted in a side wall of the waveguide section so that the tuning pin is disposed opposite the switchable semiconductor arrangement.

Patent DE-3577230-D1 (DE)
Inventor: MORRISON LARRY EDWARD
IPC: G01N33/50
Filed: 1985-09-27
Granted: 1990-05-23
Abstract: Improved binding assay methods involving determining the presence of analytes in samples through enzymatic formation of detectable substances in amounts related to the amount of analyte present in the sample and monitoring for the presence of the substances in distinct phases. Methods according to the invention include use of labelled materials which associate with the analyte to be determined or compete with the analyte for association with an added binder. The labelled materials employed include label portions which enzymatically from substances from substrates provided in or existing as a first phase, or, upon enzymatic treatment in a first phase, disassociate into substances capable of existing in or as a second distinct phase. Formation of the detectable substances is monitored by determining the transfer of the substance to a second distinct phase in contact with the first phase or by determining formation of a second distinct phase. The improved assays are useful in determining human IgG protein in blood samples and other constituents of blood or other biological samples without elaborate instrumentation, allowing for practice outside the clinical laboratory.

Abstract: A device is disclosed for forming a connecting transition between two perpendicularly adjoining surfaces, of which at least one surface is provided with a rigid covering, in particular ceramic tile. The device allows for compensation of the varying stresses occurring in the surfaces bounding the joint combined with adequate sealing of the area of transition. The device is intended to find application in particular as a connecting transition between the edge of a bathtub and the adjoining wall and consists of a single-piece plastic angular profile. A sealing strip with a softened sealing lip is molded onto a leg of the angular profile which is formed of hardened material so as to extend the leg. The sealing lip has an adhesive profile arranged on its outer side in the lengthwise direction of the angular profile. By virtue of its elasticity, the molded sealing lip of the single-piece profile is biased against the surface to be sealed. Because the sealing lip is kept connected to such surface by an adhesive connection, it always acts against such surface in a sealing manner.
