Granted: 1997-09-09
Abstract: A system for preventing abnormal heating of a thermal head, which is configured with pure hardware.  In the system, when a temperature of the thermal head becomes an abnormally high temperature exceeding a predetermined temperature and/or an active time of a print-time setting signal cyclically issued from a microcomputer for activating the thermal head only for a time period necessary for printing of one line of picture image becomes abnormally long, a flip-flop is set so that three sorts of switch circuits are respectively operated in such a manner as follows, whereby the abnormal heating of the thermal head can be prevented at a very high reliability.    (1) The supply of a drive voltage to the thermal head for heating the thermal head is forcibly stopped.    (2) The input of the print-time setting signal to the thermal head is forcibly stopped.    (3) A picture image signal supplied from the microcomputer to the thermal head is cut off and, instead of the picture image signal from the microcomputer, a signal indicative of a non-printing picture image, e.g., all-white picture image, is forcibly supplied to the thermal head as the picture image signal.

Abstract: A method of manufacturing a folding balloon catheter for use as an angioplasty device,  wherein the balloon catheter has atherotomes attached to the exterior of the balloon,  includes  inflating a balloon to  its  expanded state.   A plurality of patches of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches.   The inflated  balloon,  with  attached  atherotomes,  is  then partially cured to more firmly attach the atherotomes to the balloon.  The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps in the balloon between the atherotomes.   The deflated balloon  is  then  cured  to  completion  to  establish  a permanent  set  in  the  flaps  which  enable  the  balloon catheter to be repeatedly inflated and deflated during operation  between  predictable  expanded  and  contracted configurations.

Title: Excavation apparatus
Inventor: PACEY BRIAN
IPC: E02F5/00
Filed: 1992-12-16
Granted: 1998-10-27
Abstract: An excavation apparatus includes a tank partitioned into two isolated chambers. One of the chambers is adapted to hold fresh water and communicates with a flexible wand to be carried by operating personnel.  The other chamber is adapted to hold excavated material and communicates with a flexible hose also to be carried by operating personnel.  A single, positive displacement vacuum pump driven by a motor is selectively connectable to one or both chambers through a series of valves and hoses. Depending on the valve positions, either the intake or exhaust port of the vacuum pump is in communication with one or both the chambers.  The vacuum pump can therefore by used to fill the front chamber with fresh water as well as to pressurize the front chamber so that the water held therein can be discharged through the wand under pressure sufficient to dislodge earth at the excavation site. The vacuum pump can then be used to draw the dislodged earth and discharged water into the other chamber.  When the other chamber becomes full, the vacuum pump can pressurize that chamber to discharge the contents therein via the flexible hose at a location away from the excavation site.

Abstract: Long-chain ketene dimers are prepared in a process in which in the absence of an organic solvent, carboxylic acid chloride is fed, with intensive mixing, into a recipient of triethyl amine at a rate of not more than 3 moles/hour per mole of present triethyl amine, and the mixing rate, feed rate, and heat exchange are so attuned to each other that the viscosity of the mixture always is less than 250 mPa.s, measured at 60°C (rate of shear higher than 100 1/sec).  The process is characterized in that the molar ratio of the total amount of carboxylic acid chloride fed in to the recipient amount of amine is 1 : 1,025 to 1 : 2, and, after the conversion, the reaction mixture containing the ketene dimer is treated with diluted aqueous hydrochloric acid or an aqueous solution of triethyl amine hydrochloride and hydrochloric acid, and the ketene dimer is separated.  The ketenes prepared in accordance with the present invention are highly suitable for use in paper sizing.

Filed: 1995-08-28
Granted: 1999-09-21
Abstract: A system and method for controlling a data encoder buffer is disclosed, including an encoder for encoding input data as a first bit sequence in a bitstream; a processor having a predetermined size for converting the first bit sequence to a sequence having the predetermined size; and a decoder  for decoding the modified bit  sequence.   The modified bit sequence is generated by inserting bits to the first bit sequence.  The encoder encodes the input data at a rate such that a final capacity of the data buffer is less than a  function of  the predetermined size,  a desired decoding rate,  and an initial capacity of the encoder buffer.  The data buffer has a total buffer capacity which is less than a function of the actual rate and the desired decoding rate.  In an exemplary embodiment, the capacity of the data buffer is less than one half the capacity of the decoder buffer.  A method is also disclosed for controlling a data buffer comprising the steps of receiving input data; encoding the input data using an encoder to generate a first bit  sequence;  detecting a condition of  the  first bit sequence having a size of less than a predetermined size; converting the first bit sequence having the less than the predetermined size to a second bit having the predetermined size; receiving the bitstream; and decoding the second bit sequence.

Lesdites particules ne sont soumises à aucun revenu avant d'être envoyées sur la surface et cela élimine pratiquement les fêlures de contrainte dans lesdites particules ferreuses, ce qui empêche pratiquement tout matériau ferreux issu des particules de s'incruster dans la surface de la pièce traitée, le matériau particulaire incrusté étant susceptible de rouiller.
Patent CA-2176882-C (CA)
Inventor: ALI IRFAN
IPC: G01S5/00
Filed: 1996-05-17
Granted: 2004-11-02
Abstract: A mode of communication for asset tracking units involves communication between a central station and the individual tracking units, usually through a satellite link. This mode is the primary communication link for tracking the assets. A second mode is the local area network (LAN) or "mutter" mode, in which a subset of tracking units communicate with each other in a mobile LAN. This mode is used as the secondary communication mechanism to conserve power, since mutter mode communication requires much less energy for local communication between the tracking units as opposed to direct satellite communication with the central station. In addition, mutter mode leads to increased reliability of the asset tracking system by enabling tracking of units which have batteries too weak to support communication with the central station, but strong enough to support communication in mutter mode. The mutter mode is also useful in finding tracking units which are not communicating with the central station due primary communication equipment fault or other inhibiting condition.
