Patent EP-0218328-A3 (EP)
IPC: E21B44/00
Filed: 1986-08-07
Abstract: Information on tooth wear is obtained from the frequency 
distribution spectrum of a vibrational quantity influenced by the 
impact of cutter teeth on the bottom of a bore. In the illustrated 
example spectra are obtained from the product of torque and 
torsional acceleration and tooth wear is indicated by the shift 
upwardly in frequency of a pronounced peak occurring at T1 for a 
one eighth worn bit and at T5 for a five eighths worn bit. Other 
quantities which may be used, singly or together to enhance 
spectral information, are weight on bit, vertical acceleration, 
transverse acceleration, standpipe pressure. Abrupt changes in 
frequency distribution curves indicate abrupt occurrences such 
as broken teeth or stuck cones. A stuck cone is also indicated by 
unidirectional peaks in a plot of torsional acceleration against 
time.

Abstract: A resonant-tunneling heterojunction bipolar transistor 
(RHBT) device, having a superlattice structure and a PN jun­
ction, includes an emitter layer (17), a base layer (14), a collec­
tor layer (13) operatively facing the base layer to form a PN 
junction at the face between the base layer and the collector 
layer, and a superlattice structure (16) including at least one 
quantum well defining a sub-band of energy at which carriers 
resonant-tunnel therethrough, formed at least in the emitter 
layer and operatively facing the base layer.

Abstract: Apparatus suitable for processing semiconductor slices, the 
apparatus comprises a tank (1) for receiving a jig carrying 
semiconductor slices, a first supply line (2) for supplying a 
processing liquid to the tank (1), a supply valve (3) for 
controlling liquid supply through the first supply line (2), the 
supply valve (3) being operable in response to changes in fluid 
pressure at a control port (4) of the supply valve (3) and a second 
supply line (5) for supplying fluid to the control port (4) to 
control operation of the supply valve (3). The second supply line 
(5) communicates with an inlet (8) of the tank (1) via a control 
valve (7) which is operable in response to changes within the tank 
to control the fluid pressure at the control port (4) and so 
control operation of the supply valve (3).  
     In the arrangement shown in Figure 1, a valve member (7a) of 
the valve (7) is carried by a platform (9) pivotally mounted within 
the tank (1). The weight of a jig carrying semiconductor slices 
acting on the platform (9) causes the platform (9) to tilt to close 
the control valve (7) thereby increasing the fluid pressure at the 
control port (4), causing the supply valve to open and so supply 
liquid to the tank via the inlet (1′).

Title: Method and apparatus for removing pseudo-sync and/or automatic gain control pulses from a video signal
IPC: H04N5/913
Filed: 1987-09-16
Abstract: Added pseudo-sync pulses and AGC pulses are removed from a video signal to enable acceptable video recording thereof. The added signals previously interfered with acceptable video recording of the video signal because the automatic gain control of videotape recorders sensed false recording levels, while conventional televisions receivers were unaffected by those modifications to the video signal. Removal of the added pulses permits acceptable video recording of the previously modified video signal. A selectively-operable clipping circuit is used to remove selected negative-value components (i.e., pseudo-sync pulses) from the video signal, while added AGC pulses are effectively blanked from the video signal with an electrically-operable switch. Both the blanking and clipping functions are selectively achieved by sensing both the normal sync pulses of the video signal and the added pseudo-sync pulses. Method and apparatus are disclosed for "cleaning up" video signals modified by the pseudo-sync pulses alone, the AGC pulses alone, or combinations thereof.

Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension. Following the extrusion, the molding extension is advanced downward, in the embodiment illustrated, and serves as an implement for forming the inner shape of the reduced-diameter region or regions of the body part, and as an opposing thrust element for the blow-mold pieces which press together a region or regions of the tubular preform segment.

Title: Control of section rolling mill trains
IPC: B21B37/46
Filed: 1989-06-19
Abstract: When rolling sections in universal stands of continuously operating section rolling mill trains, it has been found that changes in the speed ratios between the horizontal rolls and the vertical rolls lead to undesired material flow changes. As a result of the horizontal roll speed, the deformation in the section parts, the resulting transverse flow and the external forces at the roll gap, a certain speed is produced in the vertical rolls in proportion to the horizontal roll speed. Any change of the edge conditions of the rolling process leads to a change of the speed ratios between horizontal and vertical rolls. In order to eliminate these disadvantages, it is proposed to control the speed of the vertical rolls of the universal stands to influence optimally the horizontal roll speed and the vertical roll speed via a control device and to obtain a minimal pull between stands via a further control.
