Title: Heating apparatus with an auxiliary exhaust opening
Inventor: KASAI ISAO
IPC: H05B6/80
Filed: 1990-04-18
Granted: 1995-04-04
Abstract: A cooking heating apparatus has a vapor sensor for sensing the state of heating of food in a heating chamber, thus performing automatic control of the heating operation.          An auxiliary exhaust opening for allowing vapor from the heated food to be introduced to the vapor sensor is formed in a region where the flow of the vapor is not influenced by a main flow of air supplied into the heating chamber and flowing towards a main exhaust opening.  The vapor sensor is disposed so as to be exposed to the vapor introduced through the auxiliary exhaust opening.  The condition of the vapor is therefore sensed quickly without being influenced by the main flow of air.
Patent CA-2014969-C (CA)
Inventor: TANNO MASAYA
IPC: H03K5/135
Filed: 1990-04-19
Granted: 1999-11-09
Abstract: A delay circuit includes a memory addresses of which is designated by a counter incremented in response to each clock signal from an initial value set by an initial value setting circuit to an end value. A digital signal is written into an address as designated and read and converted into an analog signal to be outputted at an output terminal through a buffer amplifier. A delay time is determined by the writing timing and the reading timing of the digital signal. If the delay time is to be varied in the course of a delaying operation, a further initial value is set in the counter. A control signal for returning the counter to the initial value is generated by a first signal generating circuit when the end value is reached and a setting completion signal is generated by a second signal generating circuit when a setting of the further initial value is completed, and in response to both the signals, a muting signal is generated by a muting signal generating circuit, whereby the buffer amplifier mutes the output signal in response to the muting signal to prevent a noise due to random data from occurring at the output terminal.

Title: Medication infusion device with dose recharge restriction
Inventor: LAGUETTE STEPHEN W
IPC: A61M37/00
Filed: 1990-11-23
Granted: 1995-04-04
Abstract: A   subcutaneously   implantable   medication infusion device includes a variable capacity reservoir for receiving and storing fluid medication for delivery to  a  catheter  which  directs  the  medication  to  a specific infusion  location  in  the  body.    A  control assembly is interposed between the reservoir and the catheter to facilitate and control the transfer of the medication from the reservoir to the catheter in a safe and efficient manner.  The control assembly includes a self-recharging pump and a normally closed valve, both of which are manually actuable by percutaneous pressure when subcutaneously implanted, and defines a portion of a  fluid  flow  conduit  between the  reservoir  and  the catheter.    The  control  assembly  is  constructed  to permit the infusion of a measured bolus of medication on demand through manual percutaneous manipulation of the  control assembly.   A  restrictor is provided the control  assembly  to  limit  the  rate  the  pump  is recharged with medication, to restrict the total amount of medication which can be pumped into the catheter over a given period of time.   In one preferred form, the pump recharge restriction is created by providing at least one capillary-like fluid pathway through which the recharge fluid must pass before entering the pump. In  another  preferred  form  of  the  invention,  the recharge  flow  rate  of  medication  into  the  pump  is restricted by a wick restrictor.

Title: Method of and means for providing information to edit a video tape
Inventor: ROGGENDORF PETER
IPC: G11B27/32
Filed: 1990-05-10
Granted: 1996-01-02
Abstract: An editing device for half-inch video tape applies pulse-width modulation to prerecorded synchronizing pulses in predeter-mined intervals. The inverval starts with an eleven-bit header (44) compatible with the VASS system. Pulse-width modulated time codes (48) identify the recording session and the elapsed time are then added. A check code (60) completes the modulation for fifty-hz systems, e.g. PAL and SECAM. For sixty-hz systems, e.g. NTSC, a ten-bit dummy code (62) is added to complete the in-terval. The code is entered without writing over the leading edge of the prerecorded synchronizing pulse, allowing the timing of those pulses to continue without interruption. An editor can locate any desired interval and can then locate an individual frame within that interval by counting synchronizing pulses.

Title: Synthetic peptide specificity of anti-myelin basic protein from multiple sclerosis cerebrospinal fluid
Inventor: WARREN KENNETH G
IPC: A61K38/16
Filed: 1991-10-22
Granted: 2002-03-12
Abstract: Human basic myelin protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, which span the h-MBP from about amino acid residue 61 to about ammo acid residue 106. The synthetic peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Accordingly, intrathecal administration of selected synthetic MBP peptides may be used as a treatment for Multiple Sclerosis by neutralizing anti-MBP.

Title: Generation of hard copy color photo reproductions from digitally created internegative
Inventor: MANICO JOSEPH ANTHONY
IPC: H04N1/46
Filed: 1991-12-17
Granted: 1997-03-18
Abstract: A hybrid multiple color print reproduction scheme for a digital color image photo-finishing system employing a digitally driven high spatial resolution color printer converts a stored digital positive (e.g. RGB-representative) color image into a second digital color (e.g. CYM-representative) image. This second digital image effectively corresponds to a mirrorreversed complement of the positive color image and is digitally adjusted such that its tone and color characteristics optimize reproduction of the posi-tive image via a conventional chemical development process. The complement color image is output to a digital printer (20) which prints an "internegative" image onto a transparency medium (22), rather than the customary print paper. This digitally produced "internegative" (22) is used to replicate multiple copies of the original image (16) using a conventional analog electro-optic sys-tem (21, 28) and an associated chemical-based print developing unit (30), thereby providing a substantial savings in reproduction time and costs.
