Patent CA-2145625-A1 (CA)
Title: Perforator Blade for Paper Products and Products Made Therefrom
Inventor: OGG RANDY GENE
IPC: B26D5/00
Filed: 1991-11-27
Abstract: Disclosed  is  a  perforator  blade  for  core  wound  paper products, such as toilet tissue and paper towels.  The perforator blade has a relatively narrow notch width and a relatively narrow tooth width.  As the notch width and tooth width of the perforator blade are decreased, the total notch width, which is the aggregate of  the  width  of  each  notch  across  the  total  width  of  the perforator blade, is similarly decreased.     A  perforator  blade  according  to  the  present  invention provides   very   high   perforation   bond strengths,   joining superimposed  plies  in  face-to-face  relation,  without unduly increasing the tensile strength of the lands bridging adjacent sheets of the core wound paper product.  Also,  individual  tooth flexibility  is  increased  according  to  the  present  invention resulting in enhanced perforator blade life and perforation bond quality.   Perforated  paper  products  according  to  the  present invention  also  exhibit  less  lint,  reducing  hygiene  problems, reduced  occurrences  of  sheet  tearing  during  dispensing,  and provide a smoother, better finished appearance during dispensing.

IPC: C10K1/16
Filed: 1993-10-11
Abstract: The invention relates to a process and equipment for purifying flammable gas (G), in particular low-tem-perature carbonization gas (SG). In this case, the gas (G) is scrubbed and discharged as pure gas (R). Conden-sate (U) is discharged. It is provided that the conden-sate (U)  is distilled in a distillation unit (4). The volatile constituents  (F) are admixed to the pure gas (R),  whereby  the  calorific  value  of  the  latter  is increased. The non-volatile constituents  (N)  are dis-charged. They can be fed to a low-temperature carboniz-ation drum (7) and carbonized therein at low temperature. The pure gas (R) can be used as fuel gas for the low-temperature carbonization drum (7).

Patent CA-2168809-A1 (CA)
Title: Pavement reconstruction
Inventor: KNEELAND REGINALD J
IPC: E01C23/06
Filed: 1996-02-05
Abstract: Pavement repairs are made by a single person working alone with the new repair apparatus.  Blacktop is stored in a sander bin on a truck.  An operator periodically replenishes a hopper from the sander bin by aligning the hopper under a discharge assistant of the sander bin and activating the discharge assistant.  Standing on a platform at the side of the frame, the operator moves hydraulic controls to move a carriage with hydraulic cylinders from side to side and back and forth on a frame cantilevered from the rear of the truck and anchored to the truck body beneath the sloping sides of the sander bin.  The operator aligns an auger guide mounted on the carriage with a hole and lowers a digging auger into the hole.  Loose material is removed by air blasts and vacuum.  The operator then raises the digging auger and moves the carriage to align the lower end of a sloping discharge chute over the hole.  A hydraulic motor is activated to drive a discharge auger in the chute to fill the hole with material from the chute and the bin.  Roller support arms are then pivoted downward to swing a roller outside the chute downward into contact with the repair.  The operator moves the carriage and the roller back and forth over the repair.  The support arms and the roller are raised before the carriage moves the digging auger to the new holes.

Patent CA-2169746-A1 (CA)
Inventor: PHOENIX SIMON JAMES DANIEL
IPC: H04B10/70
Filed: 1994-09-08
Abstract: In a communication system using quantum cryptography for the distribution of a key, two stations each independently modulate a single-photon signal. The single-photon signal is transmitted to the two stations from an external source, and passes through the stations in series. The signal subsequently passes onto a third station which detects the state of the signal, and compares it with the state of the signal as originally transmitted.  This third station communicates the results of the comparison to the two stations, and the two stations establish a shared secret key for the subsequent encryption of traffic between the stations. Both the source of the single-photon signal and the single-photon detector may be combined in a transmitter station (Alice).
