Title: Frequency synthesizer
Inventor: KUENL OTMAR
IPC: H03L7/22
Filed: 1992-11-27
Abstract: Abstract Frequency Synthesizer Frequency synthesizers for generating different channel spacings with short transient recovery times are commonly based on the analysis principle (mixer). This requires several phase-locked loops and expensive filters. Ambiguities are unavoidable. With a small channel spacing, the switching speed is limited by the transient recovery time of the phase-locked loop. The frequency synthesizer according to the invention uses only two phase-locked Loops (PLL1, PLL2) which both have an operating frequency (f1, fz) substantially greater than the channel spacing. The frequencies of the phase locked loops are derived from a common reference frequency (fref). By varying the division ratios of the frequency dividers (D1 ... D4) provided in the synthesizer, different channel spacings and different operating frequencies can be set. The reference frequency is derived from a crystal-controlled, temperature-compensated oscillator.            (Fig. 1)

Title: Electromagnetic fuel injector with stamped disk valve seat
Inventor: WAHBA BRENT J
IPC: F02M51/06
Filed: 1993-06-29
Abstract: ELECTROMAGNETIC FUEL INJECTOR WITH STAMPED DISK VALVE SEAT          ABSTRACT OF THE DISCLOSURE         An electromagnetic fuel injector having a housing with a solenoid disposed therein.  The solenoid operates an armature valve member relative to a valve seat in a valve seat disk to meter fuel through said valve seat and to the orifices of an orifice director plate disposed below the valve seat disk.  The valve seat disk is constructed of a thin sheet material which is punched to form a fuel passage therethrough.  The punching operation results in a raised annular ridge about the perimeter of the passage.  The raised annular ridge forms a valve seat which may be further reduced in height by machining.  The machining has the additional benefit of placing a valve seating surface on the valve seat for fluid tight sealing with the valve member.  A fuel injector having a valve seat disk constructed using this method will have a reduced sac volume between the valve seat and the orifices of the orifice director plate resulting in improved injector performance.

IPC: B65H51/14
Filed: 1993-11-18
Abstract: In known removal apparatuses for elongate material, the roller chains on which the clamping jaws are fastened must be manually retensioned. If this retensioning does not take place soon enough, increased wear of the roller chains and of the chain wheels can occur. The novel removal apparatus has tensioning elements (41) which exert a tensile force in the direction away from the drive chain wheels (33) on the at least two tensioning chain wheels (35) which are displaceable with their bearing housings (37) in the longitudinal direction of the roller chains (19). A self-locking wedge (99) prevents the tensioning chain wheels (35) from oscillating back and forth. The automatic resetting of the roller chains (19) reduces the wear of the removal apparatus (17) and avoids speed changes during transportation of the elongate material (23). The removal apparatus according to the invention is suitable in particular for transporting cables and pipes. <IMAGE>

Title: Magnetic water activating process and apparatus for reducing corrosion and lime deposits from flowing water
Inventor: GRAF STRACHWITZ MICHAEL
IPC: C02F1/48
Filed: 1992-03-17
Abstract: Reducing corrosion and lime deposits caused by water impurities on surfaces exposed to water is performed by the presence of magnetically treated water. It is found that the reduction of corrosion or encrustation is much more effective if water from a magnetically treatment unit (1) is passed over the affected surfaces to flush them as directly as practically possible and at as high a flow speed of practically possible. Water that has been used to flush these surfaces is recycled through the magnetic treatment apparatus (1) by means of a pump (8) and used to flush the affected surface again. Deflecting devices of the magnetically treated water are useful for flushing the affected surfaces effectively. A helical heat deflector inside a pipe can produce a spiral flow in a pipe for bringing as much of the treated water into contact with the walls of a pipe. A system of nozzles (10) is useful for directing flows of treated water along the walls of a tank. A spiral loop (12) with perforations facing a heating element or a cluster (11) of heating elements is useful for directing magnetically treated water at surfaces of heating elements. Magnetically treated water can similarly be used in cooling towers and air treating installations.
