Title: Capless closure for a fuel tank filler pipe
Inventor: GRAVINO MARC C
IPC: B60K15/05
Filed: 1991-09-11
Abstract: CAPLESS CLOSURE FOR A FUEL TANK FILLER PIPE            Abstract of the Disclosure A hinged flapper valve is mounted to swing between open and closed positions with respect to a fill open-ing formed through a base mounted in the outer end portion of a motor vehicle fuel tank filler pipe, the flapper being swung to its open position as an incident to insertion of a fuel nozzle into the filler pipe.  A locking ring is rotatably supported on the base for turning between locked and unlocked positions and, when in its unlocked position, frees the flapper to swing to its open position.  When the locking ring is turned to its locked position, it draws the flapper into tight engagement with the base to seal the fill opening therein and to hold the flapper securely closed.  Turn-ing of the locking ring between its locked and unlocked positions may be effected automatically by a motor adapted to be controlled from inside the vehicle.

Title: Process for continuous production of cottage cheese from ultrafiltered milk
Inventor: JENSEN POUL F
IPC: A23C19/028
Filed: 1990-07-12
Abstract: Continuous production of cottage cheese from ultrafiltered milk, preferably skim milk. The milk is subjected to heat treatment and is optionally preacidified before it is ultrafiltered to the solids content desired in the final cheese grains, viz. 18.5-21 % by weight. The retentate is subjected to another heat treatment and is then admixed with either glucono-.delta.-lactone (GDL) in an amount giving a final pH value of 4.2-4.7, or a thermophilic starter culture. In case of acidification with GDL the mixture is immediately introduced into a coagulator. If a starter culture is used, the mixture is kept at 36-42 ·C until a pH value of down 5.4 has been obtained, before it is introduced into a coagulator.  Optionally, in both cases a small amount of rennet may additionally be added before the introduction into the coagulator. The coagulator is kept at 25-35 ·C when the mixture has been admixed with GDL, and at 36-42 ·C when it has been admixed with a starter culture, and the resulting curd with pH 4.2-4.7, which is squeezed out of the coagulator, is cut to cheese grains. The cheese grains can be poured directly into a cream dressing to form cottage cheese, or they may be after-treated by heating in permeate from the ultrafiltration and washed in cold water before they are mixed with a cream dressing.

IPC: G06F19/00
Filed: 1992-03-19
Abstract: Abstract of the Disclosure A computer system for recording patient care results for retrospective analysis in a primary care out-patient environment provides, in the present system, for entry of separate, linked electrocardiographic (EKG) or chest x-ray (CXR) test results (or both) for a database of patients.  Entry of the EKG and/or CXR results prompts the creation of a separate lab record, if not already present, which may be holding blood work from the same lab test request.  Portions of information entered in the EKG or CXR routine are automatically transferred to the separate lab record.  Provision is made for linking the EKG or CXR records to the lab record in both "source" and "non-source" situations; a "source" situation meaning that the lab test request was made formally during an office visit, and a "non-source" situation meaning that the lab test request was made informally, such as by telephone.  Two print generation programs pull together various linked data files and selectively print out information contained therein.  The first prints out EKG and/or CXR data in conjunction with other clinical observations recorded at the primary care "parent" office visit.  The second prints out specialist data in conjunction with other clinical observations recorded at the primary care "parent" office visit which prompted the referrals.          The present system further includes a revision of the system's specialist record from an earlier work for more explicit use in information management.

Inventor: VAN DER TOL JOHANNES J G M
IPC: G02B6/126
Filed: 1992-09-09
Abstract: This invention provides a wavelength division multiplexer and a wavelength division demultiplexer by combining a wavelength-selective mode converter (3) with a wavelength-independent mode splitter (5).  The demultiplexer comprises a monomodal input channel (1), an adapter (2) to the bimodal input of a 100%TX00-TY01(.lambda.1) mode converter (3), a bimodal junction channel (4), and a mode splitter (5) having a first output channel (6) and a second output channel (7), both monomodal, the first output channel (6) having a higher propagation constant than the second. A .lambda.1 component, which propagates with a polarisation TX(TE or TM) in an input signal Si1(.lambda.1,.lambda.2,.lambda.3,--), will, after conversion in the converter (3), propagate in the intermediate channel (4), in the first-order guided mode having the polarisation TY (TE or TM), and subsequently leave a splitter via output channel (7).  The remainder of the input signal is not affected by the converter, therefore remains in the zero-order mode in the intermediate channel (4), and will leave the splitter (5) via output channel (6).  The multiplexer operates in the opposite direction.  Advantages: Completely producible in integrated form, no fabrication steps of a different type required other than for the fabrication of the connecting optical waveguide.

Title: Treatment of water
Inventor: SATCHELL DONALD P JR
IPC: C01B13/10
Filed: 1992-11-24
Abstract: Oxygen is separated from air by pressure swing adsorption in plant 2. The oxygen is passed through an ozone generator 4. The resulting ozonated oxygen is passed upwardly through a contactor 6 countercurrently to the flow of a side stream of water to be treated with ozone. The side stream containing dissolved ozone flows from the contactor 6 to a mixer 8 in which it is mixed with a main stream of water. The effluent gas from the contactor 6 contains air displaced from the water and undissolved oxygen.      It is divided into two parts. One part flows to the pressure swing adsorption plant 2 and is separated therein with the air. The other part is dried by temperature swing adsorption in drier 20 and the resulting dried gas is ozonated in the ozone generator 4 with the oxygen from the plant 2.

Title: Method and apparatus for video signal bandwidth reduction with high quality compatible signal
Inventor: THOMAS GRAHAM A
IPC: H04N7/26
Filed: 1992-05-15
Abstract: A temporally-subsampled video signal from a bandwidth reduction encoder is processed prior to transmission in order to reduce the judder effects that would otherwise be present when the encoded signal was viewed directly on a receiver not equipped with a bandwidth reduction decoder. A fraction 1/N of the samples are transmitted in the first field of each group of N fields, where N is the temporal subsampling ratio. Each of the other N-1 fields is formed by projecting the first field along the estimated motion trajectory to the appropriate time instant and adding to this projection the difference between another group of the N/1 samples and an estimate of these samples derived from those transmitted in the first field. At the decoder, the projected fields and the estimate of the samples can be derived from the samples in the first transmitted field of the group for each subsequent field. Using this information, the values of the other sets of samples can be derived from the subsequent transmitted fields, yielding the original temporally-subsampled signal. This signal is then decoded by the bandwidth reduction decoder.
