Title: Lawn mower discharge opening cover and deflector
Inventor: SCHWEITZ KENNETH D
IPC: A01D34/63
Filed: 1990-01-26
Abstract: LAWN MOWER DISCHARGE OPENING COVER AND DEFLECTOR            Abstract of the Disclosure A material deflector is provided for a lawn mower.  The deflector is swingably carried by the mower housing and need not be removed when a bagger attachment is used.  The deflector is shiftable between a first position above and biased against the mower grass bagger and a second position in registry with the mower discharge outlet.  When the deflector is in registry with the rear discharge outlet, it deflects the cut material to the side of the mower.  The deflector includes two adjoining material deflector surfaces, the first surface sloping downwardly and to the side and the second surface sloping rearwardly and to the side.  The two surfaces meet to form a generally right angle or L-shape material deflector rather than a traditional tubular channel for conveying of the cut material.

Abstract: RANDOM-ACCESS DIGITALLY-TUNED OPTICAL FREQUENCY SYNTHESIZER Abstract A digitally tuned optical frequency synthesizer includes a laser control arrangement for tuning the laser over a range of frequencies. The laser is tunable in response to different magnitudes of injected bias current. A digital processor determines bias current values which produce the desired different operating frequencies corresponding to a set of Fabry-Perot resonant frequencies. Those current values are stored in the digital processor for ready retrieval. During operation, one of the bias current values is retrieved and is applied to the laser. If the laser characteristic curve has drifted, an incremental bias current is determined and is added to the retrieved bias current value. For future use, this new bias current value is stored in the digital processor in place of the originally retrieved bias current value. The digital processor additionally calculates new bias current values for all of the desired frequencies of operation and stores those new values for subsequent selection.

Abstract: ABSTRACT OF THE DISCLOSURE A method of manufacturing  a vehicle seat  cover and bonding  the vehicle seat  cover to  a foam  bun utilizing  a style  insert.  The  style insert is formed by taking a breathable cloth fabric and laminating it to a sheet of foam material.  me composite so  formed is then cut to a  desired styled insert shape and sewn to the vehicle seat cover skirt to form a seat cover assembly. The composite, which may include an air impermeable barrier sheet or the barrier sheet may be included in the composite between the foam  and fabric sheets,  is positioned  on  a forming  tool having  removable  style inserts, with  the cloth  side of  the composite  against the  insert.  An impermeable film  is then  positioned  over the  foam  side of  the  insert composite and a vacuum drawn between  the forming tool and the  impermeable film to draw the composite down into conformity with the style lines of the tool insert.  An adhesively coated foam bun is then positioned and  pressed against the composite on the forming tool.  Heat is applied to the  forming tool to  evaporate  the film,  allowing  the  adhesive to  bond  the  cover assembly to the foam  bun and release the  composite from the forming  tool allowing removal of the seat assembly from the forming tool.  me edges  of the skirt are then fastened together or to the underside of the foam bun so as to at least partially enclose the bun.

Title: Automated trash compactor system
Inventor: BURGIS STEPHEN A
IPC: B30B15/26
Filed: 1990-08-27
Abstract: An automated trash compaction system having an hydraulic cylinder displacing a ram to compact trash in a mobile trash container and having an electronic control unit controlling the displacement of the ram.  The electronic control unit generates a ram forward signal in response to a start signal, generates a part-full signal in response to electrical current being supplied to an electric motor driving a fluid pump exceeding a part-full value, and generates a full signal in response to the current being supplied to the electric motor exceeding a full value.           After a predetermined full stroke time or upon the generation of the full signal, the electronic control unit terminates the ram forward signal and generates a ram return signal returning the ram to a retracted position.  The ram return signal is terminated when the current to the electric motor exceeds a predetermined value.  The electronic control also has calibration subroutines for automatically generating the predetermined full stoke time, the part-full value and the full value.     , .

Abstract: A wideband connection between subscribers G and B is throughconnected in a digital time switch module. Information arriving from the transmitting subscriber G is stored in a speech store (SS) on store locations (SM) corresponding to the channel numbers (8, 11, 17, 31) of G. The receiving subscriber B is assigned channels (7, 14, 21, 26). The channel numbers of G are stored in store locations (MM) of a matrix store (MS), and can be read-out via horizontal (HI) and vertical (VI) inputs. A fixed address number (6) is stored in a pointer store (PS) on store location (PM) corresponding to the channel numbers of subscriber B. When establishing the wideband connection, an internal address number (M) is written into a difference store (OS) on a store location (OM) having the address of the fixed address number (6). A time slot counter (TSC) steps forward the time slots (7, 15, 21, 26) of subscriber B and addresses the pointer store (PS), wherein the address number (6) addresses the difference store (OS). On each addressing occasion, the internal address number (M) is read-out to one of the vertical inputs (VI = 18) and the time slot counter (TSC) addresses the horizontal inputs (HI) at the same time. The channel numbers of subscriber G in the store locations (MM) address the speech store (SS) and the content of the store locations (SM) are read-out to the channel numbers of subscriber B. Only the internal address number (M) need to be written-in when establishing the connection.

Title: Tfel edge emitter structure with uniform light emission filter
Inventor: ASARS JURIS A
IPC: H05B33/02
Filed: 1991-03-18
Abstract: W.E. 55,471 ABSTRACT OF THE DISCLOSURE     A TFEL edge emitter structure with an EL stack having a linear array of spaced-apart pixels with front edge faces emitting light of non-uniform intensity from different regions has an uniform light emission filter provided across the light-emitting faces of the pixels. The filter takes the form of an exposed photographic emulsion coated directly to the light-emitting faces of the pixels.  Alternatively, the filter takes the form of  a  separate  substrate  containing  the  exposed photographic emulsion mounted across the light-emitting faces of the pixels.  The exposed emulsion is darker at regions thereof which correspond  to regions  of the light-emitting edge faces of the pixels with higher original light intensity and lighter at regions thereof which correspond to regions of the light-emitting edge faces  of  the  pixels  with  lower  original  light intensity.    The  final  exposed emulsion reduces the original non-uniform intensity of the light from the different regions of the pixel light-emitting faces to an uniform level equal to that of the lowest original light intensity of the pixel light-emitting faces.  A focussing lens can be combined with the edge emitter structure.   The filter emulsion is exposed so as to compensate  not  only  for  non-uniformity  of  light intensity of the structure but also for optical non-uniformities of the lens.

Title: Hydraulically propelled pneumatically returned valve actuator
Inventor: ERICKSON FREDERIK L
IPC: F01L9/10

Abstract: PHA 40.593                                         02.04.1991 ABSTRACT: Hydraulically propelled pneumatically returned valve actuator.     An actuator which is used, for example, to operate an internal combustion engine poppet valve is configured to open the poppet valve by means of a high pressure hydraulic fluid. This fluid powers the actuator piston and, at the same time, compresses air to accomplish both damping of the piston and conversion of the kinetic energy of piston translation into potential (pneumatic) energy. The actuator is held or captured in the second or valve-open position by a hydraulic latch and when released, is returned by the stored pneumatic energy to its initial position. Damping of the returning actuator piston is accomplished by a separate adjustable pneumatic orifice arrangement to assure gentle seating of the poppet valve.
