Patent CA-2070782-A1 (CA)
IPC: A47L9/18
Filed: 1991-01-16
Abstract: S u m m a r y The  Vacuum  Cleaner  features a  vacuum chamber (3), in which a negative pressure is generated by a blower (6),  and an liquid  container  (4)  arranged underneath vacuum chamber. The vacuum chamber (3) is separated from  the liquid  container (4) by a  partition (19) with an  aperture in the center, which is shielded by a cover (21).  A  suction  line  (9)  leads  to the bottom of the liquid container (4). It transports the dust into the liquid container (4), where it is bound by water.  To tran-quilize the turbulences developing in the liquid, lamellae (11) are arranged transverse to  the suction  line (9)  in staggered position  to  each  other  and  extending only over part of the cross section of the vacuum chamber (4). This  configuration as well  as  the  arrangement  of  the  cover  (21) prevent liquid particles from being swept along into the vacuum chamber (3).

Title: Microwave bread and method of preparation
Inventor: SAARI ALBERT L
IPC: A21D2/16
Filed: 1992-09-15
Abstract: MICROWAVE BREAD AND METHOD OF PREPARATION         ABSTRACT           Disclosed are fresh, baked bread products having extended shelf lives which are prepared specifically to be reheated/refreshened in a microwave oven employing a metallized film susceptor sleeve.  Upon this microwave refreshening, the reheated loaves are characterized by a soft interior crumb and a crispy crust.  The products have a shelf life of about 7-14 days.  Also disclosed are methods for preparing such baked bread products as well as full formulation dry mixes and partial formulation pre-dry mixes for their commercial scale production by both the sponge dough and straight dough methods.  The preparation methods involve first prehydrating a defined dough conditioner system and pregelatinized starch to form an emulsion, combining the emulsion with the other ingredients to form a dough and finish preparing the dough to produce a finished microwave baked bread loaf.  The finished baked goods are importantly characterized by an improved lipid distribution and enhanced resistance to toughening upon microwave refreshening.

Patent CA-2084146-A1 (CA)
Inventor: FULLER RICHARD C
IPC: H04N1/00
Filed: 1992-11-30
Abstract: Non-intrusive monitoring and analysis of real-time facsimile transmissions is accomplished. Analog impairment measurements are made on the high speed page signal in those transmissions and protocol analysis is made on the low speed control messages in those transmissions. These measurements and analysis are a powerful tool for trouble shooting service problems afflicting facsimile transmissions. Real customer traffic can be monitored to detect circuit impairments and to evaluate service being provided. A selected incoming trunk of a central office switch is accessed and a monitoring function with respect to that trunk is established. A signal classification operation is performed, which identifies the presence of a facsimile transmission and what kind of facsimile transmission it is. When the classification operation has determined the presence and nature of a facsimile transmission, a series of non-intrusive impairment measurements is made using the page information sent in the course of the facsimile transmission. Analog transmission impairments are identified along with signal to noise performance. Echo and delay measurements are also taken and the protocols are tracked. The measurement data is collected and analyzed to ascertain whether or not the facsimile transmission was normal. A diagnostic module uses the measurements to determine why any given transmission was abnormal.

Abstract: 2100877 9212755 PCTABS00014 Apparatus and method for delivering over-sized or large bore devices (80) through passageways (20) in the body. The apparatus comprises an elongated inflatable balloon (33) having an inner diameter slightly larger than the outer diameter of the device (80) to be introduced into the passageway (20). A guidewire (37) may be utilized to assist introduction of the balloon (33) into the bodily passageway (20). A device introduction chamber (50) is attached at the proximal end (35) of the balloon (33) for temporarily housing the device (80) being introduced into the passageway (20), and the device (80) itself includes a delivery shaft at least partially disposed in the introduction chamber. An inflation device (69) is provided for inflating the balloon with a biologically compatible fluid (77) once the balloon (33) has been inserted into the bodily passageway (20). The distal portion of the balloon is inserted into the bodily passageway, the balloon is then inflated to expand and straighten the passageway, and the device may then be advanced through the balloon into the passageway. The inventionis particularly useful for introducing over-sized devices through smaller, secondary passageways into larger, primary passageways, such as through the femoral artery into the aorta. After the device has been advanced within the balloon into the larger, primary passageway, the balloon may be ruptured to free the device from the balloon, allowing the device to be further advanced through the passageway to a destination such as the heart.

IPC: A61M5/31
Filed: 1992-02-20
Abstract: A multiple pharmaceutical syringe (160), especially useful for use in dispensing insulin, includes a body (162) housing first and second pharmaceutical-filled cartridges (182, 184). The cartriges are of the type with a septum (190) at one end and a piston (224, 225) at the other end with the liquid pharmaceutical (226, 228)between the two. The body also defines an accumulator chamber (202) within which an accumulator piston (238) is slidably mounted.  When the cartridges are mounted within the body, the septums are pierced by hollow spikes (188) which are connected to a flow path opening into the accumulator chamber. Check valves (230) are used at the distal ends of the spikes to prevent liquid flow back into the cartridges. Pressing on the cartridge pistons forces the liquids into the accumulator chamber. Once the desired amounts of both liquids are in the accumulator chamber, the needle assembly is mounted to the replaceable fluid path assembly which fluidly couples the needle to the accumulator chamber. The injection is given by driving the accumulator piston using the accumulator stem.

Title: Error recovery mechanism for software visible registers in computer systems
Inventor: DATE YUUKI
IPC: G06F11/14
Filed: 1994-02-07
Abstract: ABSTRACT OF THE DISCLOSURE    A CPU is so structured as to include a CSVR which stores, the same contents as a software visible register (SVR) of one cycle earlier.  Upon occurrence of an error in a calculation unit, an error flag is activated.          At the same time, data at the time of error occurrence are written into the SVR. The activation of the error flag inhibits writing into the CSVR.  In this case, the instruction which was being executed when the error occurred is restarted by restoring the contents of the CSVR into the SVR. On the other hand, if an error is detected in the CSVR, the instruction is restarted with the contents of the SVR restored to the SVR.          Error processing is accomplished under the control of a diagnostic processor.  By setting the mode flag appropriately, an instruction is given as to whether firmware for the generation of the timing of control shift to the diagnostic processor is to be gone through or not.
