Patent NO-164489-C (NO)
Inventor: PROUGH JAMES ROBERT
IPC: D21D5/00
Filed: 1985-05-07
Abstract: @ The latency of mechanical pulp is removed in a quick and simple manner. After refining of comminuted cellulosic material in a refiner (12) to produce mechanical pulp, the pulp is fluidized at a consistency of about 5-30% to remove latent properties. For instance, the pulp is diluted (if necessary) to a consistency of between about 5-30% (preferably 8-15%), and the pulp is then merely pumped to a further treatment stage. Pumping is effected utilizing a centrifugal pump (15) which fluidizes the pulp, the fluidization imparting sufficient energy to the pulp to remove the latent properties. The pulp may be pumped to a storage stage (23) prior to passage to a screening stage (21), and can be pumped in a direct (non-return) path (20) from the pump to the screening stage. If desired or necessary, a portion of the pumped pulp can be recirculated (in line 26, 26') and pumped again to ensure that sufficient energy is imparted thereto to effect latency removal.

Title: Flexible intervertebral stabiliser, and process and apparatus for the determination or control of its tension before placing it on the spine
Inventor: BREARD FRANCIS HENRI
IPC: A61B17/58
Filed: 1990-02-02
Granted: 1996-01-16
Abstract: The present invention relates to an inter-vertebral stabilizer having one or more flexible ligaments. Each flexible ligament can be engaged with two respective vertebrae and/or associated with two retaining elements, such as screws, each of which is suitable for being implanted in a respective vertebra. The present invention also relates to a process, and the associated apparatus, for determining or verifying the tension of such an inter-vertebral stabilizer before it is put into place on the spinal column. This process includes implanting, in each of the vertebrae concerned, a corresponding rigid rod extending outside the patient's body. The rods in each pair of adjacent rods are immobilized in an initial position. If the pain which is to be removed by the stabilizer persists, the process includes modifying the distance between the rods, then in immobilizing the rods in their new relative positions and in repeating the pain test. This cycle of operations is repeated, if necessary, until the pain disappears. The length to be allocated to the ligament is deduced from the distance then attained between the two rods.

Title: Laser rough and finish machining of hard materials
Inventor: ISLAM MAHMUD U
IPC: B23K26/08
Filed: 1990-02-07
Granted: 1995-04-25
Abstract: A method of laser machining hard material workpieces comprises the steps of applying a high energy, short duration laser pulse to a succession of spots on the surface of a workpiece, the duration, wavelength, and energy and of each laser pulse being such that said energy is substantially completely consumed in vaporizing a controlled quantity of material from the surface of the workpiece, the vaporized material creating a plasma cloud over each spot, each successive spot being sufficiently displaced from the previous spot to minimize the effect of the plasma cloud thereon, and the spots eventually overlapping so as to cover the whole of a desired area to be machined.  In this way, hard materials such as ceramics can be machined to high precision with minimal formation of microcracks.

IPC: G06F11/10
Filed: 1990-11-30
Granted: 1995-05-16
Abstract: A multimedia protocol interface for 64 kbit/s data flow organised according to the frame structure specified in CCITT Recommendation H221, and transmitted and received according either to the standard 64 kbit/s protocol or the 256 kbit/s IOM protocol,  is provided which can operate either autonomously or aided by an external microprocessor. It comprises a receiver, a transmitter, and control block and means for local loop testing of the operation of the interface.  The external microprocessor can read both the received data and information relating to the receiver operation, and can also send data to be transmitted or can read information relating to the transmitter operation. The receiver receives data,  and clock and  synchronism signals,  and outputs the received data,  associated with timing signals useful for external devices connected to the interface for data recovery.  The transmitter transmits the data, receives clock and synchronism signals, and supplies data and timing signals to the external devices.   Local testing is carried out by verifying whether the receiver succeeds   in  recovering  synchronism  from  a  signal transmitted by the transmitter of the same interface, under microprocessor  supervision,  and  whether  the  data  are correctly transmitted and received.

Title: Separator for producing moist, granular blasting agent
Inventor: KEIZERS SIGRID
IPC: B24C7/00
Filed: 1990-06-09
Granted: 2001-10-09
Abstract: The invention relates to a device for blasting with a moist granular me-dium in which a water/blasting agent mixture with a relatively high moisture content is conveyed by a stream of air to a blasting pipe. The invention is aimed at keeping the sand fluid with a relatively high addition of water as far as its entry (1) into the conveyor agent pipe and ensuring that after its exit (2) from the blasting pipe it contains only just enough residual moisture to pre-vent dust formation either through the discharging blasting agent or from sur-face particles removed. This aim is achieved by the invention in that a device (5) is fitted in the conveyor circuit of the device for blasting with moist granu-lar agents in front of the blasting agent entry to separate out the superfluous water.

Abstract: A fluid density measuring tool is set forth, a structure having a shielded sonde supporting a radiation source having a characteristic gamma ray emission pattern preferably in all directions of azimuth, and a cooperative first detector is disclosed. Ports aligned with the first detector and source preferably limit the gamma ray pathway primarily to the fluid surrounding the tool.

This provides sufficient measurement data enabling one to sort the data and thereby determine the bulk density of the fluid in the well.
Patent CA-2048081-C (CA)
Inventor: IGUCHI KESAYOSHI
IPC: G06F15/17
Filed: 1991-07-29
Granted: 1996-07-09
Abstract: A method of controlling data sending and receiving operations between two microprocessors.  A first controlled-side microprocessor receives an optional one of a data sending request signal and a data receiving request signal from a second controlling-side microprocessor.  The first microprocessor also receives a select signal of a logic OR signal of both request signals, and determines if the optional one request signal indicates "receiving request" or "sending request" at the same time when it responds to the select signal, thereby executing the requested operation.          Hence, even if the first microprocessor does not receive the select signal and the sending/receiving signal at a time, the first microprocessor can determine simulta-neously with the receipt of the select signal if it should send or receive the data, resulting in a higher-speed data processing.

Title: Ink jet printing apparatus
Inventor: CARLOTTA MICHAEL
IPC: B41J2/175
Filed: 1991-08-23
Granted: 1996-09-10
Abstract: In an ink jet printer, a printhead assembly comprising a printhead and an ink reservoir is mounted on a scanning carriage for movement across a recording medium. During printing, droplets of ink are expelled from ink channels within the printhead and the channels are replenished with ink which is drawn in from the reservoir. The reservoir is connected to an ink source from which ink is supplied during printing and when the printhead assembly is being primed. A partition within the reservoir ensures that, during priming, air can be expelled from the reservoir through the ink channels, thereby avoiding the need for an air vent from the reservoir.
