Abstract: An extrusion tool for making a drill bit blank provided with an internal rinsing bore extending helically in a longitudinal direction of the drill bit blank, includes a nozzle having an inner wall defining a throughgoing axial bore through which a malleable material is passed in a direction of extrusion parallel to the tool axis. The axial bore forms an inlet portion and a mold chamber adjoining the inlet portion downstream thereof as viewed in the direction of extrusion. There is further provided a mandrel situated in the inlet portion; a resiliently deformable wire supported by the mandrel and projecting into the mold chamber; and a helical device provided on the inner wall in the mold chamber for twisting the malleable material as it passes through the mold chamber. There is further provided a clamping device having a tightened state for immobilizing the nozzle and the mandrel with respect to one another during extrusion operation. In the loosened state of the clamping device a positional adjustment of the nozzle with respect to the mandrel may be made.

Filed: 1988-05-13
Abstract: A desired positive fractional stuffing ratio is obtained in a frame 
synchronizer for a digital signal having a channel frame format that included 
two stuffing bit positions to obtain either positive or negative stuffing. The 
fractional stuffing ratio is obtained by controllably increasing (via 504, 507 and 
508) the duration of a first predetermined number (p) of intervals during which 
data bits are written into the synchronizer and, then, by controllably decreasing 
(via 504, 507 and 508) the duration of a second predetermined number of 
intervals (q-p) during which data bits are written into the synchronizer. A data 
bit (D) is forced to be included in one of the stuffing bit positions occurring 
during each of the first predetermined number (p) of intervals and a non-data 
bit (X) is forced to be included in one of the stuffing bit positions occurring 
during each of the second predetermined number (q-p) of intervals.

Title: Method and apparatus for filtering invalidate requests
IPC: G06F15/177
Filed: 1989-05-30
Abstract: A method and apparatus which filter the number of 
invalidates to be propagated onto a private processor bus 
are provided. This is desirable so that the processor bus 
is not overloaded with invalidate requests. The present 
invention describes a method of filtering the number of 
invalidates to be propagated to each processor. A memory 
interface filters the invalidates by using a second 
private bus, the invalidate bus (46), which communicates with 
the cache controller. The cache controller can tell the 
memory interface whether data corresponding to the address 
on the invalidate bus (46) is resident in the private cache 
memory of that processor. In this way, the memory 
interface only has to request the private processor bus 
when necessary, in order to perform the invalidate.

Title: Headlamp with sloped lens including beam-spreading flutes
IPC: F21S8/10
Filed: 1990-03-26
Abstract: This headlamp for a motor vehicle comprises a 
lens that has a front surface (31) that slopes backwardly from 
bottom to top of the lens. In localized regions of the 
lens, there are spread flutes, each comprising alter­
nating ridges (28) and grooves (29) on the back surface of the 
lens. The individual ridges extend in a direction be­
tween the top and bottom of the lens and are character­

base-up cone. The individual grooves (29) extend in a direc­
tion between the top and bottom of the lens and are 
characterized by having the form of a segment of an 
upright, base-down cone. The coniform configuration 
of the individual ridges (28) and grooves (29) serves to lift the 
edges of the light beam passing therethrough and thereby 
compensate for the tendency of the beam to droop at its 
edges as a result of the backward slope of the front 
surface (31) of the lens.
