Patent CA-2118465-A1 (CA)
Title: Interrupt information generating apparatus and speech information processing apparatus
Inventor: FURUHASHI MAKOTO
IPC: G06F3/16
Filed: 1994-10-19
Abstract: An apparatus for generating the interrupt information includes an addressing device for generating the specified address information for specifying the desired information stored in a memory device, a readout address generating device for generating the readout address information of the desired information stored in the memory device, and a comparator device for comparing the specified address information from the addressing device and the readout address information from the readout address generating device and for generating the interrupt information in case of coincidence of the specified address information and the readout address information and supplying the interrupt information to a central processing unit.      Since the interrupt data is supplied to the central processing unit at the playback timing of the desired sound source data, reproduction of the sound source data can be detected, so that it is unnecessary for the central processing unit to poll the address of the sound source data at all time and hence the load imposed on the central processing unit may be correspondingly decreased.

Patent CA-2120148-A1 (CA)
Title: Protection device for signal and power carrying line
Inventor: ATKINS IAN PAUL
IPC: H02H3/08
Filed: 1992-09-22
Abstract: A module for insertion into a combined signal and power carrying line, especially into a CATV line, for protecting a system associated with the line from an overcurrent comprises (i) a housing (50)having connection ports (51, 52) for cables (53,54) forming the line and being, impedance matched to the line, one of the conductors of the cables being connected together via a capacitor (23); and (ii) a solid-state overcurrent protection circuit that is connected, across the capacitor via inductors ~ to isolate it from the signal on the line, the protection circuit being capable of switching from a conducting to a blocking state in response to an overcurrent and being capable of resetting itself or attempting to reset itself into its conducting state one or more times after it has switched into its blocking state. If line containing a number of such modules is subjected to an overcurrent, the protection device in the nearest module upstream will switch so that only that part of the line downstream of the module will be affected. In addition, tracing the location of the fault is much simpler because the section of the line in which the fault occurred is known from the protection circuit that has tripped.

Patent CA-2121990-A1 (CA)
Title: Antibody-drug conjugates
Inventor: BARTON RUSSELL L
IPC: C07K16/00
Filed: 1994-04-22
Abstract: ANTIBODY-DRUG CONJUGATES        The science of pharmaceutical chemistry has progressively provided more and more specific and potent drugs for the treatment and prevention of illnesses. However, until quite recently, there has been no means to direct a drug to the specific part of the body where it is needed.  Thus, although it is often possible to treat a patient with a drug which has the specific effect which is needed, and no other effect  on the body, it is still necessary to administer a whole-body dose.  On the other hand, if it were possible to direct a drug to the organ, tissue or even cell in need of the treatment, it would often be possible to administer an extremely small total dose, since the drug would concentrate itself where it is needed.  The advantage in safety to the patient and economy of the drug is obvious.          For some years now, the science of immunology has been attempting to provide such targeted treatments, by conjugating drugs with antibodies which are directed to specific antigens associated with the locations where the drug is needed.  Patents and scientific articles concerning such antibody-drug conjugates are now numerous.  However, up to the present time, no antibody-drug conjugate is approved for therapeutic use.          The present invention provides a physiologically acceptable drug conjugate of Formula I

Patent CA-2127295-A1 (CA)
Title: Peptide linkage unit comprising methylene phosphinic acid
Inventor: JANDA KIM D
IPC: B60W40/09
Filed: 1993-01-11
Abstract: A peptide linkage unit is employed for joining peptide and pseudopeptide sequences, including peptides and pseudopeptides that inhibit aspartic proteinase enzymes. The peptide linkage unit includes a phosphinate methylene ammonium linkage in place of a peptidyl carboxamide bond. If the peptide linkage unit is incorporated into a peptide sequence that would otherwise serve as an aspartic proteinase substrate and if it is positioned at a cleavage site within such peptide sequence, the phosphinate methylene ammonium linkage is resistant to cleavage and serves as an exploding transition state analog of such cleavage site. When so incorporated, the phosphinate methylene ammonium linkage can bind or interfere with the active site of aspartic proteinase enzymes and inhibit its activity. Preferred inhibitors contain a phosphinic acid methylene amine group joining the P1 and P1' residues and have a length of 3 to about 15 amino acid residues.

IPC: A61B17/30
Filed: 1994-07-06
Abstract: A tick removing device having an open sleeve with a tick removing end and an actuating end. A gripping device is disposed and movable in the sleeve. A main body is disposed within the sleeve and extends out from the tick removing end of the sleeve and provides an elongated slot that extends from an intermediate portion of the sleeve down the main body portion of the gripping device and out the tick removing end of the sleeve. The slot defines two spaced apart main body portions forming a pair of movable gripping legs that extend out from the tick removing end of the sleeve. The legs include a pair of tick gripping points. A connecting portion of the gripping device extends from the main body through the sleeve towards the actuating end of the sleeve, and includes a slotted terminal end that includes at least one locking projection. A detachably connected movable actuator button disposed within the actuating end of the sleeve has a hollow sleeve within the elongated sleeve. The actuator button includes a spring stop portion that is formed about an internal end of the actuator button. A shoulder formed internally within the elongated sleeve functions as a spring stop. A spring is engaged on one end with the actuator button and on the other end with the shoulder for withdrawing the gripping legs of the main body portion into the sleeve. A fixed spreader pin secured within the sleeve disposed within the slot of the main body portions causes the gripping legs to spread toward an open position and release of the actuator button causes the gripping device to be moved towards the actuating end of the sleeve. The sleeve then constricts the gripping legs to be moved towards a closed position.
