Abstract: An installation for sorting out reject slugs out of the slug channel of an automatic coining machine with a slug control mechanism, whereby the reduction of the reaction time for the rejection of slugs to be sorted out permits a considerable increase of the number of coining strokes of the automatic coining machine, without the need for a further additional intermediate storage of slugs. The reject channel for rejected slugs is thereby kept closed by shaped members in the manner of shutters and is opened up in case of need whereby also the desired dimensions for the slugs are determined by the shaped members. Such a slug control mechanism is needed in the slug channel of an automatic coining machine in order to separate good slugs from reject slugs.

Abstract: A method of making a papermarker's felt which includes the steps of forming a pin seam fabric (1) having interdigitated loops (4) at the ends of the fabric joined by a pin (5). A batt of fibrous material (6) is needled into at least one face of the fabric (1) and across the pin seam joint. When the felt is to be installed on the papermaking machine, the pin (5) is removed and the felt is bent back on itself at the joint to bring the portions of the batt (6) adjacent the joint into contiguous or contacting relation and cause the loops (4) to separate. The batt (6) is then cut along a line extending through the separated loops (4) to provide a flat or opened felt which can then be installed on the papermaking machine. After installation, the loops (4) are interdigitated and the pin (5) is reinserted through the loops (4) to provide the endless felt construction.

Abstract: One of the programmable elements of the array (20) is designated as a security element (22), and its output is coupled to a latching mechanism (30). The output of the latching mechanism (30) is coupled to a mechanism (36) for disabling the read output of the array (20). The latching mechanism (30) is enabled for a short time by a pulse when power is applied to the circuit. Thus, when power is first applied, the security fuse (22) has not been set and the latch output will allow data to be read. While power is applied, all of the programmable elements can be set, including the security element (22). All the elements, including the security fuse (22), can then be verified by reading them out. When power is turned off and subsequently reapplied, the latch (30) will then be enabled and the set security fuse level will appear at the latch output, thereby disabling the reading out of the program data. The present invention thus allows verification of the setting of the security fuse (22) and verification of the other programmable elements after the security fuse (22) has been set.

Abstract: In a thread milling cutter comprising at its tip cutting edges for making a bore, said cutting edges are formed as face milling cutting edges which enclose a mutual angle of 180 DEG  or more, so that the thread milling cutter on reaching the intended drill hole depth and in order to be laterally moved need not first be raised. Also, it is possible with the thread milling cutter according to the invention when using said cutter to make threads of any desired diameter with the same thread pitch because the tool tip does not run against the drill hole bottom when laterally moved or offset as with the known thread milling cutter. In addition it is possible with the same tool to provide the thread at the entry with an edge-chamfer in such a manner that impairment thereof by formation of burrs is impossible.

Title: Method for the safe operation of turbo compressors
IPC: F04D27/02
Filed: 1989-02-21
Granted: 1992-01-29
Abstract: In the case of known control methods for turbocompressors, in order to prevent surging before the working point of the compressor reaches the surge limit, it is ensured by controlled opening of at least one venting or reversal valve on reaching a venting line parallel to the surge limit that the flow through the compressor does not fall below a minimum through-flow which varies as a function of the delivery pressure. The disadvantage to these known methods is that surging cannot always be reliably prevented, particularly in the case of rapid shifts in the working point in the direction of the surge limit. The new method is intended to avoid this disadvantage. 
<??>The new method proposes that in addition the rate at which the working point shifts in the direction of the surge limit be determined in the performance characteristics and that if a rate-related rapid opening line running at various distances from the surge limit is exceeded, rapid opening of the venting or reversal valve be superimposed on the normal venting control. This means that opening of the venting valve occurs at the latest possible moment but always in sufficient time. The compressor can thereby still be operated safely at levels closer to its limit which results in more economic partial load operation and greater surge safety. 
<??>The new method is suitable for controlling turbocompressors for widely varying applications, for example in blast furnace blast generators, in petrochemical processes or the manufacture of fertilizers.

Abstract: A control arrangement for a home entertainment unit, including a television receiver and one or more peripheral devices, such as a video recorder, coupled to the television receiver, includes a single remote control transmitter for transmitting a remote control signal to the television receiver, which, in turn, passes on control instructions to the peripheral devices. To allow such a remote control operation, even when one or more of the peripheral devices is produced by a manufacturer different than that of the television receiver and which therefore requires a different remote control code, the television receiver has a memory in which, under the control of a microprocessor, the remote control codes allocated to respective function control keys of the remote control transmitter supplied with a peripheral device are stored during a learning process. During the learning process, the screen of the television receiver displays messages for instructing the user which function control key of the remote control transmitter associated with the peripheral device to press. Thereafter, when a device function control key of the remote control transmitter supplied with the television receiver is pressed, the microprocessor, working in conjunction with the memory, converts or translates the codes contained within the received remote control messages to codes corresponding to the peripheral device and a correspondingly encoded remote control signal is relayed by the television receiver to the peripheral device.

Abstract: The invention relates to a control device for a lift installation without a speed sensor, having an induction motor (3) for driving a lift cab (5) which approaches a floor level indicated by a marking (8) from an initial marking (7) at a crawling speed, and having a VVVF invertor (2) which supplies the induction motor (3) with current. The VVVF invertor (2) measures the real current (Ia) supplied to the induction motor (3) when the lift cab (5) moves at a constant speed before reaching the initial marking (7). A slip compensation unit (13) determines from the measured real current an associated slip frequency and derives from this the rotor frequency preset for the crawling phase up to the next marking (8). A function specifying the crawling time (Tc) as a function of the measured real current is stored in a memory (11). A computer unit (12) calculates from the crawling time (Tc) a delay time (Td) by which the start of the braking process of the lift cab (5) is delayed for each movement and, taking into account the delay time (Td) thus calculated, determines a new virtual extrapolated crawling time (Tcv) after each movement. Finally, a profile generator (1) drives the VVVF invertor (2) with a voltage/frequency signal (f,u) as a function of the virtual, extrapolated crawling time (Tcv). <IMAGE>
