Title: Apparatus and a method for preserving coverage in an overlapping coverage area
Inventor: BENDIXEN ARNE B
IPC: H04B7/24
Filed: 1993-10-01
Abstract: Abstract of the Disclosure:          A system which improves coverage in overlapping coverage areas between two type-A or type-B cellular radio telephone systems is able to direct a subscriber unit in the overlapping coverage area to the home or primary system, thereby minimizing the subscriber unit's roaming-type expenses.  The system includes a control channel receiver, a control unit, and a control channel transmitter/receiver pair, in combination with a transmit/receive antenna.  The system transmits a control channel, which is associated with the home system, into the overlapping region.  The control channel is intended to be the strongest channel in that region.  Any subscriber units in the region associated with the home system which respond to that control channel will be directed to other control channels associated with the home system.  Those subscriber units will receive service from the home system, as opposed to the foreign system which may provide other strong control channels in the overlapping coverage area.

Title: Missile
Inventor: BADURA WOLFGANG
IPC: F42B12/62
Filed: 1994-02-02
Abstract: ABSTRACT OF THE DISCLOSURE         The invention provides a missile which has a booster engine, a folded brake parachute in a parachute housing, a cruise engine and a warhead situated behind one another in direction of flight.   The booster engine is removable from the brake parachute prior to the brake parachute opening and the brake parachute is separable from the cruise engine when the cruise engine is switched on. The brake parachute is housed in a parachute housing which is closed toward the booster engine and open toward the cruise  engine  and  with  which  the  booster  engine  is connected via  a positive  locking  connection,  such  as flanginq or the like,  which can be released by axial tractive power.  A separation charge for disengaging the booster engine from the parachute housing is situated between the  floor  on the booster engine  side  of  the parachute housing and the booster engine.   The booster engine  is connected with the parachute housing via  a mechanical parachute release mechanism which becomes active with delay vis-à-vis the igniting of the separation charge to release the brake parachute from the parachute housing.

Patent CA-2117561-A1 (CA)
Inventor: MOLLER PAUL J
IPC: H04W88/02
Filed: 1993-12-29
Abstract: A nondirectional antenna assembly, and associated method, for a radio operative at high frequencies, such as at frequencies of approximately 1.8 Gigahertz. A first antenna portion, formed of a one-half wavelength, helical winding is supported at a distal side of a nonconductive whip. A second antenna portion, comprised of a helical winding supported at a proximal side of the nonconductive whip, and a one-quarter wave helical winding, connected to radio circuitry of the radio transceiver, couples the first antenna portion to the radio circuitry. Because the first antenna portion is positioned at a distal side of the nonconductive whip, shadowing occurring as a result of positioning the radio transceiver proximate to a user during operation thereof is less likely to interfere with operation of the radio transceiver.

Title: Method for the electrolysis of an aqueous potassium chloride solution
Inventor: HOENIGSCHMID-GROSSICH RUEDIGER
IPC: C25B15/08
Filed: 1994-08-02
Abstract: Abstract Disclosed is a process for the electrolysis of an aqueous potassium chloride solution, in which the sulphate ions are removed from the solution by precipitation as potassium sulphate and/or as potassium sulphate-containing salt mixture and/or as potassium sulphate-containing compound.  The precipitation is achieved by increasing the hydroxide ion and/or carbonate ion concentration in the potassium chloride brine, for example by addition of potassium hydroxide and/or potassium carbonate.  The sulphate ions are preferably precipitated from the depleted brine at temperatures higher than the saturation temperature of potassium chloride.  The method according to the invention is applicable to the amalgam, diaphragm or membrane process of electrolysis of potassium chloride.  The method avoids the use of expensive and toxic precipitants in particular barium salts, reduces the amount of filter sludge and provides potassium sulphate which can be used, for example, in the fertilizer industry.

Title: Rotating Mower Baffle Mechanism
Inventor: KUHN JOHN B
IPC: A01D34/82
Filed: 1994-09-09
Abstract: A mowing mechanism having a spindle rotatively driven by a power source, a blade having a radially inner portion coupled for rotation with the spindle and a radially outer portion for cutting vegetation, a housing within which the blade rotates, and a disc operatively carried within the housing for rotation with the blade and having a radially outer portion spaced above the blade.  The disc includes an inner portion extending radially inwardly from the outer portion to a position proximate the blade, the inner and outer portions of the disc serving to confine air and clippings near the outer portion of the blade.  The rotating disc prevents accumulation of the grass clippings beneath the disc and housing, and enhances airflow within the housing due to viscous drag or friction between the disc and the air within the housing.  Deflectors carried by the disc are designed to further enhance airflows and generally deflect clippings back toward the blade for mulching.
