Title: Process for handling individual articles in a single-pass machine, as well as an apparatus for carrying out this process
Inventor: KOSIKOWSKI THOMAS
IPC: H05K13/00
Filed: 1990-06-15
Abstract: ABSTRACT OF THE DISCLOSURE    In the first instance, the present invention relates to a process for handling individual articles, in particular drilled circuit boards, in a single-pass machine that incorporates a plurality of processing stages, the parts passing through the machine at a speed of movement (v), and at least one processing stage requiring more time than the remaining processing stages.  In order to permit the continuous handling of individual articles in a simple single-pass machine that does not require much space and which also incorporates handling processes or stations that require more time, it is foreseen that handling stages that require a longer period of time are distributed in a number n of parallel tracks where n >= 2 and that the speed of movement (v') of the parts that are to be processed through the tracks that are parallel to each other in this handling stage is equal to v/n.  In addition, the present invention also relates to an apparatus in the form of a single-pass machine consisting of a plurality of handling stations or stations to carry out the above-cited process, these being arranged in a series, one after the other, each station or stations that requires or require a longer processing time than the other stations consisting of a plurality of parallel tracks that provide fox identical processing.

Title: Method of correcting error on involute interpolation
Inventor: TAKAO SASAKI
IPC: G05B19/18
Filed: 1990-07-12
Abstract: ABSTRACT           An involute interpolation error correcting method corrects an error on involute interpolation in a numeri-cal control system for machining gears and pump vanes. The method corrects an insufficient cut in an actual configuration of a workpiece which is machined along a first involute curve (In1) that is commanded.  A radius of curvature (Rs) from a base circle (C) to a starting point (Ps3) of the insufficient cut on the first involute curve (In1), and an error (De) which occurs at an ending point of the first involute curve (In1) in a direction normal to the insufficient cut, are determined from the machined configuration, and set as parameters in the numerical control system.  On interpolation from the starting point (Ps3) of the insufficient out to the ending point (Pe1) of the first involute curve, a first offset at the time the first involute curve is interpo-lated is changed to a second offset which is increased from the first offset by the error (De).  On interpola-tion up to a point (Ae1), the offset is restored to its original value.  The configuration which is machined according to the above process is free of the insuffi-cient cut. An excessive cut can be prevented when the offset is reduced.

Title: Transmission lubrication system
Inventor: SCHAFER HELMUT
IPC: F16N7/40
Filed: 1991-08-22
Abstract: ABSTRACT OF THE DISCLOSURE    The scavenging pump action of a clutch is used to ensure an adequate supply of oil to the sump at any angle of operation of the transmission.  The clutch preferably is placed at the front of the transmission, so that during downhill operation when the sump might be drained, oil can be pumped by the clutch back to the sump.  The sump preferably is provided with a lip on the top portion thereof, so that a cup is formed at one end to retain oil in these extreme angled positions.  An overflow passage between the main transmission housing and the clutch to allow oil flow therebetween preferably is positioned such that no such oil flow is allowed during normal operation, but ample oil flow is allowed during extreme hill operation to insure that sufficient oil is pumped back to the sump.
Patent CA-2050041-A1 (CA)
Inventor: YASUKAWA NIHIKO
IPC: B60R11/02
Filed: 1991-08-27
Abstract: An apparatus and method is provided for the support of an accessory unit within the defined space of a storage area. The storage area is preferably a floor-mounted console receptacle or a dashboard receptacle commonly found within the seating compartment of an automobile. The support structure provides a mounting plate that supports a radio telephone unit within the receptacle by spanning the space separating side walls of the receptacle. Engaging Velcro attachment elements mounted upon both side flanges of the mounting plate and the receptacle side walls permits the mounting plate supporting the radio telephone unit to be easily installed or removed within the receptacle. The use of Velcro elements to removably install the mounting plate within the receptacle eliminates the need for fastening screws, nuts and bolts, or rivets to mount a support structure within the storage area. In an alternative embodiment, a support structure includes a U-shaped mounting bracket that supports an accessory unit within a dashboard receptacle. A pair of support arms, attached to a center connecting bar of the mounting bracket, are spaced apart by approximately the distance separating the space between receptacle side walls.     Upon inserting the mounting bracket within the receptacle, an angular tab located on each of the support arms engages one of the receptacle side walls and tends to act as a barb to frictionally retain the mounting bracket within the receptacle.          A projection located on either side panel of the accessory unit mates with a corresponding projection installation hole positioned on each support arm to removably install the accessory unit within the installed mounting bracket and thereby mount the accessory unit inside the receptacle. This eliminates the need for any fastening screws to install the accessory unit to either the mounting bracket or the face of the dashboard receptacle.
