Abstract: A fluorosis-free ingestible fluoride ion-containing composition comprising a mixture of pharmaceutically acceptable fluoride and monofluorophosphate in a weight ratio to provide not more than about fifty percent, and preferably not more than about twenty-five percent, of available fluoride ion from the fluoride and the balance from the monofluorophosphate. By "fluorosis-free" composition is meant one which, when ingested, minimizes of obviates the occurrence of fluorosis which is a common effect when fluoride is ingested. The composition may contain additional pharmaceutically acceptable adjuvants, such as vitamins, coloring, flavoring, carriers, stabilizers, preservatives, medicants and the like, and may be in the form of a powder, tablet, capsule, pill or a liquid in a suitable ingestible carrier. Preferred compounds are alkali metal, ammonium and amine fluorides and monofluorophosphates. Most preferred compounds are sodium fluoride (NaF) and sodium monofluorophosphate (MFP), whose formula is Na₂FPO₃ and the corresponding potassium salts. 
     The compositions are especially adapted for use as a dietary supplement to provide substantially instantaneous low-dosage fluoride ion from the fluoride compound upon ingestion and a slow, prolonged release of fluoride ion from the monofluorophosphate.

Abstract: Rotor-equipped machine for Wire Straightening and cutting, which is composed out of a single or many units for the straightening and cutting of a single or many Wires simultaneously. 
     Each unit consists of a Straightening System, which includes the Straightening Rotor (3) and the Mechanism (48-51) for the reciprocating motion of the Wire (1) inside the Rotor, a Cutting System (5), which includes the Double-Position Cutter (12), a two-channel Receptor (9), a System for the automatic control of the length to be cut and a free space for temporary storing of the Wire (1) between the Straightening (3) and Cutting System (5). 
     The method for the reciprocation of the Wire (1) inside,, the Rotor is used to avoid the rapture of the Wire (1) if for some reason it is immoblized inside the body of the Rotor (3). The Wire (1) exiting the Rotor (3) may be stored, forming under the action of its weight a "storing curve" in the empty space between the Rotor (3) and the Cutting Mechanisms (5). That way any interruption, for any reason, of the progression of the Wire (1) through the Rotor (3), during the Cutting action and its excess stress inside the Rotor (3) is avoided. 
     There is a double-action Cutting Blade (12) in the Cutting Mechanism (5), able to collaborate with the two-channel Receptor (25,26). The Wire enters one channel of the Receptor (25,26). The Cutting Blade (12) moves toward one direction, followed by the Receptor (25,26), cuts the Wire (1) and at the same time, the channel of the Receptor (25,26) opens at its lowest side, releasing the Wire being cut into the Storage Place (16,17). At the time of the Release, new Wire (1) to be cut enters the other channel of the Receptor (25,26) and it is cut and released during the motion of the Cutting Blade (12) towards the opposite direction. 
     If the machine is composed out of many Straightening (3) and Cutting (5) units, it is possible for each unit to elaborate Wire (1) of different material, properties and diameter and to cut at different length size that of the other units. The desired length to be cut is remotely controlled and programmed from a control panel, by means of an automatic control Mechanism.

Abstract: An electrical control unit (84) having a microprocessor (86) and a network of counters for governing the electrical operation of a fuel control valve of a fuel injection pump (9). Four subtraction counters are preset by the processor; one is used as a time counter indexed by time pulses and three are used as pump angle counters indexed by pump clock pulses generated for each predetermined increment of pump rotation. Two of the pump angle counters are employed to precisely open and close the valve for regulating the fuel injection timing and quantity -- the total quantity in a normal mode of operation and a pilot quantity in a pilot injection mode. In the pilot mode, the third pump angle counter regulates the main injection quantity and the time counter regulates the time delay between the pilot and main injections. Two addition counters are indexed by the pump clock pulses to determine a count of the pump angle between pump and engine reference points (ERA count) and a count of the pump angle of the valve closure response time (VRA count). The ERA and VRA counts are used by the processor in determining the preset counts for the subtraction counters. Two fixed angle counters are operated by engine clock pulses generated for each predetermined increment of engine rotation, to start and stop a speed counter indexed by time pulses to determine the instantaneous engine speed between power strokes for fuel balancing at engine idle. The processor diagnoses the reliability of the pump and engine clock pulses and when one is determined to be unreliable, substitutes the other with appropriate scaling.

Abstract: To synchronise the counting mechanism of an electronic control device with the zero position of a pointer, defined by a mechanical stop, in a display device which is driven via a step-down transmission by a stepping motor with two mutually perpendicular windings and a two-pole rotor, the two windings being alternatingly connected to a voltage source and to a measuring mechanism for determining the voltage induced in the winding without current, and the pointer being moved step by step up to the mechanical stop and the counting mechanism being set to zero if there is no induction, a method is proposed which is much less elaborate than a known method of this type. When stepping motor and display device are assembled, a particular alignment of the two-pole rotor is allocated to the zero position of the pointer and the rotor is in each case brought into this particular alignment at the beginning of the method. After that, the induction is in each case only determined in the position of the rotor following this particular alignment by one step. …<IMAGE>…

Abstract: A Monolithic Microwave Integrated Circuit (MMIC) amplifier (10) with extended dynamic range includes a base circuit (12) for receiving both a first input signal, which is the signal to be amplified, and an amplifier generated second input signal. A power amplifier (14) in the base circuit (12) directly receives and amplifies the first input signal, with some unavoidable distortion to the first input signal. A first directional coupler (18) is connected with the base circuit (12) to couple the output of the power amplifier (14) with the first input signal to cancel the first input signal component from the output of the power amplifier and generate the second input signal which is only distortion. This distortion is then amplified by an error amplifier (16) in the base circuit (12), and the output of the error amplifier (16) is coupled with the output of the power amplifier (14) through a second directional coupler (20). This coupling at the second directional coupler (20) cancels the distortion from the output of the power amplifier to provide the desired amplified signal.

Abstract: A system and process for continuous reception of information by a mobile receiver unit passing among a plurality of spaced transmitters with each transmitter configured to individually transmit signals to the mobile receiver unit. The mobile receiver unit has a pair of scanning receivers controlled by a switching control module. The module causes one of the scanning receivers to lock onto signals transmitted from one of the transmitters while causing the second scanning receiver to scan signals transmitted by the transmitters in the reception range of the scanning receiver. Once the strength of the signal locked onto by the first scanning receiver falls below a predetermined minimum signal strength, the second scanning receiver locks onto the best suited received signal and the first scanning receiver is caused to commence scanning, the roles of the scanning receivers thus being reversed. The process continues, with the roles of the scanning receivers constantly being reversed, as the mobile receiver unit traverses the signals broadcast by the plurality of spaced transmitters.
