Title: Pulsed coherent doppler laser radar
Inventor: AMZAJERDIAN FARZIN
IPC: G01S7/486
Filed: 1990-09-10
Abstract: PULSED COHERENT DOPPLER LASER RADAR               ABSTRACT OF THE INVENTION In a pulsed coherent Doppler radar,  a Q-switched laser  source  develops  a  laser beam to  have  a  high intensity  pulse  portion  and  a  substantially  lower intensity trailing tail portion.   A switching device upon which the laser beam is incident directs substan-tially all of the energy of the pulse portion along a first  propagation  path  towards  a  target,  such  as atmospheric  aerosols,  and  substantially  all  Or  the energy of the tail portion along the second propagation path.    The  target  reflects  the pulse  portion as  a received signal.  A heterodyne detector upon which each of the received signal and the tail portion is incident, determines the Doppler shift of the received signal with respect to the tail portion.  The detector uses the tail portion  as  the  local  oscillator.   The acousto-optic modulator  also  upshifts  the  frequency  of  the  tail portion.

Title: A method and device for the biological control of insects
Inventor: GUNNER HAIM B
IPC: A01N63/30
Filed: 1990-01-11
Abstract: A convenient, economical, non-toxic and effective method and means for the control of insects by attracting the insects to a high concentration of an entomopathogenic fungus, for example, Metarhizium anisopliae and Beauveria bassiana, so that they are infected by the fungus and die. The fungi are placed in the environment to be treated using means which insure contact and infection of the insects with the fungi. In the preferred embodiment for the biological control of cockroaches, the roaches are ex-posed to the fungi by means of a contamination chamber having openings through which the cockroaches enter and come in con-tact with a living culture of a fungus which is pathogenic to cockroaches. The fungal spores attach to the roach, germinate and penetrate into the body of the cockroach, resulting in the death of the infected roach. Death takes approximately two to three weeks after contact with the culture. During this time, the infected roach disseminates spores of the pathogenic fungus throughout the infested areas which may subsequently infect other roaches. Given the proper envinmental conditions, the fungus sporulates on the cadaver of the roach and the conidia can be transmitted to other cockroaches, resulting in a further spread of the disease.

Title: Low power a/d converter for an implantable medical device
Inventor: HENRY DONALD A
IPC: H03M1/56
Filed: 1991-07-18
Abstract: ABSTRACT OF THE DISCLOSURE     A low-power A/D converter for an implantable medical device.  The converter includes a high-frequency oscillator capable of generating clock pulses at a frequency substantially higher than the main clock frequency of the implantable device, and an oscillator-gating circuit for enabling the oscillator for a voltage-dependent variable time interval.  The gating circuit includes a voltage-controlled monostable multivibrator for generating a gate control pulse having a pulse width corresponding to the value of an analog signal representative of a physiological parameter sensed by the implantable device.  A timing controller, which operates at a low frequency under control of a crystal-controlled clock, supplies a trigger pulse to the voltage-controlled monostable at a predetermined first point in the variable time interval and generates an enable pulse at a predetermined second point in the variable time interval.  In response to the enable pulse, the A/D converter enables the oscillator at the second point and, in response to the gate control pulse, disables the oscillator at the end of the variable time interval.  A counter coupled to the oscillator counts the clock pulses generated between the second point and the end of the variable time interval.

Abstract: Living cells (56) which produce biologically active factors can be encapsulated within a semipermeable, polymeric membrane by co-extruding an aqueous cell suspension (54) and a polymeric solution (52) through a common port (14) to form a tubular extrudate (12) having a polymeric membrane which encapsulates the cell suspension.  For example, the cell suspension and the polymeric solution can be extruded through a common extrusion port having at least two concentric bores (16 and 18), such that the cell suspension is estruded through the inner bore (16) and the polymeric solution is extruded through the outer bore (18).  The polymeric solution coagulates to form an outer coating or membrane.  As the outer membrane is formed, the ends of the tubular extrudate can be sealed to form a cell capsule.  In one embodiment, the tubular extrudate is sealed at intervals to define separate cell compartments connected by polymeric links (58). In another embodiment, a cell capsule connected to a tethering filament (59) can be formed.

Title: Buoy for attachment to the net line of a fishing net
Inventor: LENGEFELD RALF M
IPC: A01K75/04
Filed: 1991-09-06
Abstract: ABSTRACT   In order to change defective buoys on the net line of a fishing net and to change the spacing between the buoys threaded onto the net line, it has hitherto been necessary to release the net line from the net and to re-secure it to the net after re-arranging the buoys, thus to re-tie it.  This is a very time-consuming task, which can now be avoided by use of the novel buoy.  This novel buoy consists of two identical portions,     thus of two halves, which engage against the net line and which can be assembled together effortlessly at the desired location for the complete buoy.  To connect the halves, a clamping member disposed to surround the barrel-shaped buoy in a groove can be used.

Filed: 1991-09-13
Abstract: ABSTRACT   A process and an installation for utilizing organic substances are prop-osed, in which the substances are correspondingly comminuted and proc-essed by mixing and reaction stages to utilizable compost.      The installation (100) essentially comprises a heatable fermenter (70) with a stirrer (75) located therein.  In order to obtain an approxim-ately closed process circuit the comminuted substances are supplied as so-called fresh material by a supply shaft (35) to a conveying shaft (60) constructed as a heat exchanger and undergo corresponding heating therein.  Through further supply of fresh material the already heated fresh material is supplied to the fermenter (70) and mixed therein by the stirrer (75), accompanied by further heating.            The fermented matter formed in the fermenter (70), on supplying furtherfresh material, can be admixed in a specific ratio as so-called bacterial inoculum with the fresh material throughout the process circuit.            The gases formed during the fermentation process in the tank can eitherbe used in the installation (100) as process energy or can be supplied via a line (80") to another energy supply plant.
