Abstract: Ein Schneidmesser zum Entgraten von Bohrungen besteht aus einem rechteckigen, kantenförmigen Schneidkörper mit konisch verlaufenden Schneidkanten, mit hinterschnitten angeschliffenen Freiflächen und mit einer stirnseitigen Anlagefläche am Messerkopf zur Anlage an der Innenfläche einer Bohrung. Zwei gegeneinander gestellte Schneidmesser sind in radialer Richtung verschiebbar in einer Messerführung eines Werkzeughalters gelagert und in Arbeitsstellung während der Entgratung einer Bohrung werden die Schneidmesser wegen des Vorschubes des Werkzeughalters und wegen des konischen Verlaufs der Schneidkanten gegen eine Federkraft in der Messerführung radial einwärts verschoben, bis sie schließlich nicht-schneidend den Innenbereich der Bohrung erreichen. Es soll eine Beschädigung von erstellten Fasen oder die Beschädigung der Innenfläche einer Bohrung beim weiteren Verlauf des Bearbeitungsvorganges vermieden werden. Hierzu weisen die Freiflächen einen kurvenartigen Anschliff auf unter Bildung eines am Ende des Bearbeitungsvorganges verschwindenden Freiwinkels, wobei die stirnseitige Anlagefläche jedes Schneidmessers ballig geschliffen ausgebildet ist.

Filed: 1987-09-07
Abstract: A personal computer is disclosed having a high speed microprocessor which executes in a variety of selectable speed modes to provide greater compatibility with application programs written for slower speed microprocessors. A logic means is included responsive to the speed select signal which does not change the speed of the microprocessor oscillator (clock) but rather changes the length of a wait state or "STOP" state of the microprocessor. The "STOP" state of the microprocessor is varied by varying the time delay setting of a one-shot timer. The one-shot timer keeps the "STOP" request active and therefore keeps the microprocessor (CPU) from running bus cycles (executting code) until the timer times out thereby releasing the CPU STOP. By varying the length of the time delay of the one-shot timer, which halts the execution of bus cycles (code), the microprocessor simulates microprocessor speed changes which have the appearance of earlier generation computer with older microprocessors. The computer and software disclosed enhances compatability of a faster microprocessor with older applications programs written for slower microprocessor without varying the microprocessor clock rate.

Abstract: For testing memory modules of the mega-bit generation in the multi-bit test mode with arbitrary test patterns, whereby m cells of the cell field are simultaneously tested, at least one m-dimensional test word is generated in test word registers additionally integrated in the memory module MBS, with at least one test word being subsequently mapped onto the cells of an m-dimensional cell group or of a plurality of cell groups. Simultaneously, the test word or words are supplied to a comparison logic for comparing these to the test words upon readout of the test contents of a cell group and generating a good or bad signal for indicating the result of this inverse mapping, dependent on the comparison.

Abstract: A hot profile-steel workpiece having a flange width dimension, a web height dimension, and a web thickness dimension is rolled in a roll train including a reversible univerial rolling stand and a flange-compacting roll stand unstream therefrom. According to the invention one of the height, width, or thickness dimensions of the incoming workpiece is reduced upstream of the flange-engaging compacting roll stand. Normally the web height dimension is reduced in a roll stand immediately upstream of the universal and flange-compacting stands. Furthermore the workpiece has a web with extra-thick parts and these extra-thick parts are rolled out by horizontal rolls of a roll stand that engage this web. The flange-compacting roll stand engages the faces of the flanges. With this system it is possible to make the web of the incoming workpiece either shorter or taller, that is it can either be compacted or rolled out.

Abstract: This invention relates to a cold/hot water discharging apparatus which is used for cold/hot water massage shower, and the like. In order to alternately switch and supply hot water of a predetermined temperature supplied from a hot water source (6) to a discharge portion, a valve (5) of a cold/hot water mixing tap (A) is driven by a motor (12) and is reciprocated in a pre-set period between a position where high temperature hot water is discharged and low temperature hot water is discharged. In each of the periods for discharging low/high temperature hot water, an optimum gain of this period is determined from the previous period and previous gain so as to shorten the discharge period of cold/hot water and to obtain a stable curve of the discharge hot water.

Abstract: A film made of synthetic resin is pulled continuously from a roll thereof and forms into a tubular shape the overlapping longitudinal edge portions of which are fused. The interior of the resulting tubular film is filled with a liquid or viscous material to form a tubular body fed while it is being formed. The tubular body is squeezed intermittently at a predetermined time interval by a pair of rotating cylindrical rollers to form flattened portions devoid of the material, after which each flattened portion is constricted transversely of the tubular body to form a constricted portion. An ultrasonic horn and an anvil are brought into abutting contact with the contricted portion, which is sealed ultrasonically by holding the ultrasonic horn and anvil in abutting contact therewith at a constant contact pressure for a set period of time while the ultrasonic horn applies ultrasonic waves to the constricted portion.

Abstract: A ticket processing terminal includes a cylindrical ticket guide around which tickets are driven by a single drive cylinder which rotates in the ticket guide. An entry port, a feed port, and an exit port all connect to the ticket guide in a spaced relationship around the guide. Read/write mechanisms are placed adjacent the guide at a position which is passed by a ticket entering the guide through the entry or feed port and before the exit port is passed. Tickets are issued by the terminal by providing information to the write mechanism from an external source, feeding a ticket into the guide from either the feed port or the entry port, writing the information on the ticket, reading the printed information for validation, and then diverting the ticket to the exit port before completing a revolution. After being issued, a ticket bearing written information can be processed by the terminal for cancellation. When being cancelled, a ticket is fed into the ticket guide through the entry port, advanced past the read mechanism where the information on the ticket is read, advanced on a complete revolution of the ticket guide past the exit port, cancelled by the write mechanism, and then diverted from the ticket guide through the exit port before completing the second revolution of the ticket guide.

Filed: 1988-03-02
Abstract: The unexpected synergistic interplay between lymphokines and dsRNAs which dramatically reduces the necessary dosages of lymphokines, especially IL-2, and simultaneously widens their therapeutic range in the treatment of various types of cancers, viral disorders or other body conditions characterized by disregulated immune states (e.g., autoimmune diseases). Specific combinations of dsRNA plus IL-2 significantly increase survival in human melanoma-bearing animals in part because of augmentation by dsRNA of lymphokine activated killer cells (LAK) which are first formed in response to IL-2 exposure. The invention has wide applicability to non-toxic, efficacious control of both human cancer and various human viral infections and immunoregulatory disorders.

Abstract: An information storing apparatus is provided in a radio telephone appara­tus having a base unit 1 coupled to a wired telephone line 3 and a radio tele­phone set 2. The base unit includes a memory 40 for storing telephone number information and a line relay 33 for making or breaking a speech path between the base unit and the wired telephone line. When a registration signal ( # , from key 32a) is transmitted from the radio telephone set, the base unit is disconnected from the wired telephone line to break the speech path. There­after, if a dial signal (from keys 32) from the radio telephone set is received, the received dial signal is stored in the memory as the telephone number infor­mation used for a reduced dialing operation. If a calling signal arrives at the wired telephone line while the dial signal is being stored, the calling signal is detected by another telephone apparatus 50 coupled to the wired tele­phone line. Therefore, the telephone apparatus generates a ringing signal in response to the detected signal.
