Title: Steering mechanism for a vehicle
Inventor: CRABB ELMER R
IPC: B62D11/18
Filed: 1990-05-04
Abstract: Abstract of the Disclosure Steering Mechanism for a Vehicle A vehicular steering mechanism of overly complex construction is known which displaces a left turn control valve or a right turn control valve through separated cams in response to the rotation of a steering wheel.  The subject steering mechanism is simpler, more economical and more compact by including an input shaft and a single actuating cam which are conjointly rotatable away from a neutral position in either direction.  The actuating cam defines a profiled guide slot of a substantially spiral shape, and a cam follower assembly is cooperatively associated therewith including a cam following roller wheel that is received in the profiled guide slot. The cam follower assembly includes a bellcrank supporting the roller wheel and indirectly connected to a left turn control valve and a right turn control valve.          The vehicle is steered by the controlled rotation of the bellcrank and the subsequent displacement of the control valves and.  The steering mechanism also includes an effective centering and stop assembly.

Inventor: HEDIGER DANIEL
IPC: H02K3/50
Filed: 1990-08-15
Abstract: ABSTRACT OF THE DISCLOSURE         For fixing the winding ends (1, 2, 3, 4) of a stator winding in a dynamoelectrical machine, in which the winding ends have inner (2, 3) and outer layers (1, 4), which are mechanically and electrically connected to each other at the axially outer end, the winding ends are clamped between an outer ring (14) and an inner ring (15). The bracing of the two rings (14, 15) and of said winding ends is performed by filling pieces (16) being inserted between two neighboring winding ends (1, 2) in the circumferential direction of the winding overhang, of which filling pieces at least some are wedged in the radial direction with the two rings (14, 15) by means of retightenable wedges (17, 18).     This clamping produces a rigid winding overhang, the wedging can be retightened if required and also disassembled without any great effort.                                   (Fig-1)

Abstract: Sheet material containing sodium carboxymethyl cellulose especially useful in forming wrappers for smokeable articles such as cigarettes that results in reduced sidestream smoke.      The sheet is preferably formed by incorporating as a filler in a cellulosic web an amount of high superficial surface area filler in the range generally of from about 5 to 50 percent by weight in the finished sheet. The cellulosic material may be flax fiber or other natural cellulosic fibers conventionally used for such wrappers. Additional fillers may be used up to a total of about 50 percent, and, preferably, a burn modifier, carboxylic acid salt, preferably a nonhydroxy acid salt such as succinic acid salt is included in an amount of 4 to 15 percent by weight. The sheet can be formed by any conventional papermaking method. When such papers are used as cigarette wrappers, they effect a reduction of the total particulate matter in sidestream smoke of up to about 75 percent with improved taste and odor and without serious deterioration of other desirable properties. In addition, the sheet of the invention provides normal ash appearance in a smoking article.

Abstract: An injection molding manifold fot distributing pressurized melt from a common inlet to thirty two outlets. The steel manifold has rear and forward plate portions which are integrally brazed together. The rear portion is drilled and plugged along a first transverse plane to provide the melt passage with branches from a common inlet portion to four intermediate portions. Four sets of matching grooves are machined in the joining faces of the rear and forward portions whereby each intermediate portion of the melt passage in turn branches along a second transverse plane to eight outlet portions, each leading to a cavity. The combination of the melt passage branching in several different directions in two different transverse planes with the second plane having different sets of curved portions allows the melt passage to have a large number of outlets while still having smoothly curved bends without having a leakage problem.
