Patent DE-3277924-D1 (DE)
Title: Carburetors
Inventor: MCKIM ROBERT E
IPC: F02M7/22
Filed: 1982-07-08
Granted: 1988-02-11
Abstract: The carburettor delivers one combustible fuel and a liquid, or two combustible fuels from separate reservoirs to the central portion of a hollow spray bar for discharge into the carburettor venturi. Closed metering chambers are in fuel flow communication from the reservoirs and suspended from opposite ends of a spray bar.  Fuels from the metering chambers travel through variable width grooves formed in metering inserts into the lower end portions of corresponding metering arms and then into the hollow interior of the spray bar. The orientation of the metering chamber is regulated to vary the air-fuel ratio by the cooperative action of a vacuum assembly operating in response to the vacuum level in the engine intake manifold and by both an engine temp. responsive actuator and an intake manifold temp. responsive actuator.

Title: A method in the preparation of poly(arylene sulfide)
Inventor: SHERK FRED THEODORE
IPC: C08G75/02
Filed: 1982-09-01
Granted: 1989-04-06
Abstract: A method for dehydrating pre-polymerization mixtures in the preparation of poly(arylene sulfide) in which a reaction mixture of a sulfur source and an organic amide are contacted at a first pressure within a range of about 20 psig to about 60 psig and an initial temperature in a range of about 300 DEG  F. to 400 DEG  F. to form a complex of the reactants with the mixture subsequently subjected to a decrease in pressure while elevating the temperature to a second temperature at which, at the chosen pressure, essentially all water is removed from the mixture. Other compounds including bases, alkali metal carboxylates, alkali metal carbonates, lithium halides, and lithium borate can be present in the reaction mixture. Preferably the sulfur source is sodium sulfide and the organic amide is N-methylpyrrolidone.

Title: Plate filter with movable filter cloth
Inventor: SCHOTTEN ALFONS
IPC: B01D29/00
Filed: 1983-11-30
Granted: 1987-02-12
Abstract: A plate filter comprises a plurality of shiftable filter plates and first and second deflecting rolls carried on opposite sides of each filter plate. The axes of consecutive first deflecting rolls lie alternatingly in a first plane and in a second plane spaced from one another. A filter cloth is guided in a zigzag course between consecutive filter plates by the first and second deflecting rolls. A first sprocket is affixed to each first deflecting roll and a second sprocket is mounted on each first deflecting roll for free idling rotation. First and second spaced, elongated, oppositely driven chains are respectively trained in a zigzag course in an alternating sequence about first and second sprockets of first deflecting rolls belonging to consecutive filter plates. The first and second chains are in meshing relationship with the first and second sprockets about which the chains are consecutively trained. The diameter of the first and second sprockets and the distance between the first and second planes are dimensioned for varying the magnitude of a loop angle represented by an arc along which the first and second chains are in engagement with respective first and second sprockets to compensate for length variations of the first and second chains upon shifting motion of the filter plates relative to one another.

Abstract: A method of cutting panels or stacks of panels comprises the use of only a circular cutting saw to effect extremely neat cuts at rapid rates and with no splintering. The saw will cut a panel in two steps, first by acting thereon through a portion of its thickness during a horizontal stroke, and then through the remaining portion of its thickness during the reverse stroke, while the direction of rotation of the saw remains unchanged and is such that the teeth thereof act successively on the two faces of the panel and press them inwardly of said panel. The saw can be adjusted with precision either horizontally and vertically. Before being positioned for the former of said two working steps, the saw is displaced both vertically and horizontally with precision, to effect in the side of the panel whereon the cutting stroke is initiated and terminated, one or more incisions submitting the material of said panel to inward compression, which helps avoiding the formation of splintering during the subsequent cutting operations.
