Title: Quill drive mechanism for machine tools
IPC: B23B47/18
Filed: 1974-11-04
Abstract: There is disclosed a quill advancing and retracting mechanism in which the quill is provided with a tubular extension having an external helical groove shaped to receive the ball bearings of a power driven ball screw nut. In the form shown, the tubular extension has a single helical groove having a determinate pitch, and the nut has two ball-carrying circuits, each having ball return means, the two circuits being axially offset relative to each other to preload the nut and take up the lost motion between the balls of the nut and the helical groove. The nut is driven by a timing belt connected to a stepping motor. With the combination of the preloaded ball bearing nut and the stepping motor, it is possible to control the movement of the quill so it and the tool carried by the spindle may be stopped at any point with an accuracy of about 0.0005 inches per foot cumulative, the balls in one circuit of the nut pressing against one side wall of the helical groove while the balls in the other circuit press against the other side of the groove and thus take up any lost motion between the balls and the groove.
Patent ES-438646-A1 (ES)
Title: Rotational collar alignment device
IPC: F21V23/06
Filed: 1975-06-17
Abstract: A self-contained fluorescent lamp fixture for installation in a conventional incandescent lamp socket which permits selective adjustment of the fluorescent lamp fixture through a substantial arc and which readily facilitates retention of the fixture in the adjusted position. The new fixture includes a body cover which is adapted to receive a conventional fluorescent tube as well as the other components required to make the tube operational. This cover includes a pair of opposed, generally centrally located arcuate slots and is mounted between upper and lower fixture collars by a pair of threaded fasteners. The fasteners pass between the collars through the arcuate slots whereby the cover may be selectively rotated in a plane normal to the axis of the fixture. The upper collar includes means for threadedly mounting the entire fluorescent fixture in an incandescent type lamp socket. A generally flat, compressible member is received between the lower collar and the fixture body cover such that as the upper and lower collar are brought into a closely spaced relationship with each other, the member is compressed. This action places a continuous biasing force against the cover urging it toward positive engagement with the upper collar. The fixture body cover, including the fluorescent tube, may then be rotated for alignment purposes and will be retained in the aligned position by means of the frictional force created by the compressible member urging the body cover toward engagement with the upper collar. The arcuate slots define a generally circular configuration and each extends through an arc of approximately 170 DEG whereby the cover body may be moved through an arc of approximately 170 DEG for alignment purposes.

Title: Railway vehicle speed control system - calculates parabolic curve to establish length of travel for braking, allowing for braking time
IPC: B61L27/00
Filed: 1979-12-14
Abstract: The speed control system for a railway vehicle uses a continuous monitoring system to register data regarding the vehicle speed and to calculate a parabolic curve for the braking conditions. A part of the data is obtained from a fixed point to establish a set of speed values for the vehicle. The shape of the curve thus established follows a fixed curve. This curve establishes the next value of a set of values which determines the curve. Below a predetermined minimum speed the nominal values can be used instead of the length of travel while braking. In calculating the parabolic curve used for the length of travel, the braking time is allowed for.
