Patent EP-0226537-A2 (EP)
Inventor: SCHOLZ DIETER
IPC: E21B10/58
Filed: 1986-12-01
Abstract: An axially elongated rock drill includes an axially extending shank and a drill head on one end of the shank. The drill head has a drill face extending transversely of the axial direction of the rock drill. A hard metal cutting plate and hard metal cutting pins are set in the drill face. The cutting pins reduce the wear on the cutting plate and afford better support of the drill. The cutting pins are arranged, in part, parallel to the axis of the drill, and, in part, inclined to the drill axis. The cutting plate has a cutting edge which generates a cutting plane as the drill is rotated with the ends of the cutting pins projecting from the drill face being located in the generated cutting plane.

Inventor: GRAHAM PATRICIA ANNE
IPC: H02P8/06
Filed: 1987-10-02
Abstract: By examining parity for a bit combination representing the present phase state of a stepping motor having phases A and B, a selection can be made as to which phase state should be changed in order to produce rotation of the step motor in a predetermined direction. By including within the parity determination not only the present phase state of the stepping motor, but the logic level of a direction bit (DIR), appropriate phase sequence for either CW or CCW rotation can be selected. In a hardware embodiment of the invention, a conventional parity generator module is used with inputs representing the present motor phase states as well as a logic level for a DIR bit. The output of the parity generator then determines which phase state to change to produce the desired rotation. In a software embodiment, a digital computer dedicates a phase state byte with a bit from each motor phase state and an additional DIR bit. Parity can be determined using a conditional branch on parity instruction or merely summing the phase direction byte. In either event, the state of the motor phase is changed depending upon the result of the parity determination in order to produce the desired rotation.

Abstract: A method of determining in a discrete analyzer the total sugars content of a tobacco sample containing sucrose, glucose and fructose, comprises the steps of, converting the sucrose to glucose and fructose, enzymatically converting the glucose and fructose to glucose-6-phosphate in the presence of hexokinase, reacting the glucose-6-phosphate with nicotinamide-adenine dinucleotide in the presence of glucose-6-phosphate dehydrogenase to give reduced nicotinamide-adenine dinucleotide, the amount of reduced nicotinamide-adenine dinucleotide produced being directly proportional to the total sugars content of the sample, measuring the concentration of reduced nicotinamide-adenine dinucleotide in the sample, and generating a signal indicative of the concentration of reduced nicotinamide-adenine dinucleotide and hence of the total sugars content of the sample. Deactivation of enzymes by any cyanogen bromide that may be present is prevented by the addition of dithioerythritol to the reaction mixture.

Abstract: This invention relates to an injection molding system having a number of nozzles conveying melt from an elongated manifold to a common cavity. In the preferred embodiment, each heated nozzle has a melt channel which is offset from a central valve pin bore for conveying the melt to the gate. The melt channel extends through a side portion of the nozzle which is bolted to the side surface of the manifold. The bolts provide a seal against leakage of the pressurized melt, while at the same time allow slight lateral movement between the manifold and the nozzle. This provides for thermal expansion of the manifold relative to the nozzle which is accurately located in a well in the core The system is used for large cavities which require large flow volumes and avoids the difficulty of accurate machining of the large molds to provide sealing.

Abstract: The invention relates to a housing for auxiliary devices or their storage containers. The auxiliary devices or their storage containers are fixed in the housing in a defined manner and are protected against impact or breakage. The auxiliary devices or their storage containers are fixed by elastic inserts inside the housing which yield and make the way free when inserting or removing the auxiliary device or its storage container into or out of the housing. In contrast, when the auxiliary device or its storage container is in the housing, the elastic inserts give a firm fit due to their shape. This allows the housing to be attached to the wall, in which case a handle of the auxiliary device or the auxiliary device storage container can also point downwards without the risk of the auxiliary device or its storage container becoming unintentionally detached from the housing. Additionally, the handle of the auxiliary device or auxiliary device storage container can be fixed in the housing using the subject matter of the invention without adversely affecting easy handling. <IMAGE>
