Patent EP-0282431-A2 (EP)
Inventor: KELLY JOSEPH LEONARD JR
IPC: E21B10/22
Filed: 1988-03-03
Abstract: An earth boring bit having a rotatable cutter (33) secured to a lubricated, cantilevered bearing shaft (31), sealed with an improved pressure compensating rigid face seal assembly. The assembly has a rigid ring (50) with a radial face that opposes and engages a radial face integral with a cutter seal groove (49). A resilient energizer ring (52) is compressed between opposed coni­cal surfaces, one on the rigid ring (50) and the other in a shaft seal groove (47), to force the radial faces together. The periphery of the energizer ring is inside the journal bearing surface, which is ideally aligned with the mid-section of the ring, to define an essen­tially constant, lubricant filled, volume between the seal assembly and the shaft seal groove -- even as the cutter and seal assembly move relative to the shaft du­ring drilling. As a result, pressure variations in the vicinity of the seal assembly are minimized.

Abstract: Porous mouldings are used to support grave decorations, packaging, building panels or floats. The material used is usually polystyrene foam. However, this is undesired for various applications for visual reasons and for reasons of poor biodegradability and the attendant environmental pollution. The material used in the invention is cork granules, which, optionally with added sawdust or pine needles, are baked under atmospheric pressure with gentle warming with an adhesive likewise comprising natural products, preferably a urea condensation product. The energy requirement during production is only low, and the exclusive use of regenerative natural products reduces the requirement for raw materials and enables biodegradation on waste disposal. <IMAGE>

Abstract: A error detecting circiut includes syndrome calculating circuits (3-6) which calculates quotients S₀′, S₁′, S₂′ and S₃′ by dividion of syndromes. When all of the syndromes are "0", an error zero is detected by an error zero detecting circuit (13), and a signal (ZE) is outputted. A single error detecting circuit (14) detects a single error when S₀′=S₁′=S₂′=S₃′=0, outputting a signal (1E). At this time, a J-latch (19) holds a counted value "j" of the counter (18) which counts the number of the division as data indicative of an error position. Based upon data calculated by adding circuits (7-12) and multiplying circuits (15, 16), a double error detecting circuit (17) detects that there are two or more errors through determination whether or not equations (S₀′+S₁′)(S₂′+S₃′)=(S₁′+S₂′)² and (S₀′+S₂′)(S₂′+S₃′)=(S₁′+S₂′)(S₁′+S₃′) can be formed, outputting a detection signal (2E) when double errors occur. At this time, the J-latch and an I-latch (20) hold counted values "j" and "i" as data indicative of error positions. By an error component calculating circuit (27), error components E i  and E j  are calculated by (S₀′+S₁′)/(1+α i-j ) and S₀-E i , respectively because a syndrome S₀=E i +E j .

Abstract: For successively establishing a point-to-point electrical connections between pin terminals, a path is successively searched for each pin terminal pair and a connection is established if the search path is not intercepted by obstructing paths. If the attempt fails, a plurality of routability indices are generated to evaluate candidate paths. The routability index is a measure of the likelihood of finding a new path from each pin terminal through the obstructing paths, and is specifically represented by the number of paths that can be passed through a removed segment of a given obstructing path. Priorities of different levels are derived from the routability indices and are assigned to the obstructing paths which are to be ripped up to create a path for a new connection. One of the prioritized obstructing paths is selected according to the priorities and is removed to permit a new path to be searched for to determine if it is intercepted by further obstructing paths. If the new path is found, a connection is established; if not, the removed obstructing path is replaced and a prioritized obstructing path of lower priority is removed and a further new path is searched.

Abstract: A protocol for transferring instructions between asynchronous processors in a computer system is provided. Each instruction transfer requires the transfer of an opcode and a variable number of operands. The transfer is accomplished via a bus which interconnects the processors. The opcode and operands are assembled in a buffer in the sending processor and then transferred to the receiving processor in reverse order, i.e., operands first and opcode last. The receiving processor does not acknowledge any of the transfers until it receives the opcode which is always sent last. Upon receipt of the opcode, the receiving processor knows the instruction transfer is complete and sends the acknowledge signal immediately thereafter.

Abstract: A reed valve device with an air control valve operates in response to a signal pressure applied to a signal pressure port, so as to selectively allow a fluid introduced through a fluid inlet port to reach a reed valve through a gap between a diaphragm and the valve seat on the upper end of the inner cylinder, and to cause the fluid to forcibly open the reed valve so that the fluid is discharged through a fluid outlet port. When no signal pressure is applied, the diaphragm is seated on the valve seat to prevent the fluid from reaching the reed valve. The reed valve also is capable of blocking any reversing flow from the outlet port. The reed valve device has an upper casing including an outer cylinder provided with a fluid inlet port, and inner cylinder disposed in the outer cylinder, the gap between the lower ends of the outer and inner cylinders being closed, a lower casing provided with a fluid outlet port and communicating with the interior of the upper casing through the reed valve provided between these casings, the diaphragm placed on the upper ends of the outer and inner cylinders, a cover member having the signal pressure port formed therein and provided on the diaphragm, the diaphragm being clamped at its peripheral edge portion between the cover member and the outer cylinder, a coiled spring loaded between the cover member   and the diaphragm so as to bias the diaphragm to keep it seated on a valve seat provided by the upper end of the outer cylinder, wherein the signal pressure applied to the signal pressure port produces a force to deflect the diaphragm against the force of the coiled spring away from the valve seat so as to allow a fluid introduced through the fluid inlet port to reach the reed valve through the space between the outer and the inner cylinders and through the interior of the inner cylinder, whereby the fluid introduced through the fluid inlet port into the space between the outer and inner cylinders is prevented from directly flowing into the inner cylinder. In consequence,the noise generated in the reed valve is prevented from directly propagating to the fluid inlet port, so that the level of the noise is reduced.

IPC: F04B49/00
Filed: 1990-05-26
Abstract: A high-pressure unit is described which may be a control unit for high pressures or a high-pressure pump even for non-lubricating fluid. The basic construction is a yoke controlling two reciprocating pistons, which yoke periodically feeds the propelling fluid alternately to one of the two pistons. Due to the control arrangement the return flow from the cylinders is also controlled, to be precise in such a way that the return fluid is fed to a fluid motor which is driven by the fluid return flow and drives the yoke in a rotating or in a periodically alternating movement. The unit has an inlet for medium pressure which can be connected to fluid flow generators at any points. In this way the unit may be used not only in workshops with pumps driven by electric motor but also out-of-doors wherever a medium pressure pump is available, e.g. in excavators, tunnel drilling machines,  bulldozers, etc. It is significant that with this technology a number of previously unrecognised problems arise, which do not allow related units to be used for high pressures. It is recognised that the irregular delivery largely arises from compression and expansion of fluid during the switch from one cylinder to another. Consequently the invention provides for lines, valves, pressure reservoirs and auxiliary units such as an auxiliary pump and a pressure reservoir which function at certain times and remain closed at others. The invention also recognises, however, that just one of these arrangements on its own produces extremely positive results, so that, where necessary, the further arrangements can be dispensed with. In addition, the invention also restricts or eliminates dead spaces, utilises the expansion fluid for the compression process in the next working cylinder (or the chamber), increases the efficiency of the units and/or improves the consistency of their delivery. Analysis of the basic principles of the technology leads to the findings from which the invention derives its solutions. In particular the delivery troughs of non-uniform delivery flows are overcome and the deficiencies of the known technology corrected. Thus the overspeeds of the control drive motor are limited by means of a second yoke, and the piston strokes are increased together with the deliveries of the units. In addition, radial piston and axial piston units are proposed for delivery flows with only small fluctuations and valve sets without dead space. <IMAGE>
