Patent CA-2040172-A1 (CA)
Title: Stock-rod system for determining the burden level in a shaft furnace
Inventor: HERZOG INGO
IPC: F27B1/28
Filed: 1991-04-10
Abstract: The invention relates to a plummet device for determining the height of the charge in a blast furnace. The winding drum (1) for raising and lowering a rope (5) or a chain, to the end of which is attached a plummet (6), is driven by a hydromotor (3). The shaft of the winding drum (1) drives a displacement transducer (9). The motor used to drive the winding drum (1) is a so-called slow-running hydromotor (3). A signal which is matched to the respective measurement depth is transmitted by the displacement transducer (9) directly, i.e. without electric control, to a pressure-proportioning valve (10). At the hydromotor (3), this valve sets a plummet-holding pressure appropriate to the respective depth.
Patent CA-2040509-A1 (CA)
Inventor: SANTKUYL RICHARD J
IPC: D21F3/02
Filed: 1991-04-15
Abstract: An apparatus and method is disclosed for reducing the water content of a formed web. The apparatus includes a press for pressing the formed web such that a first portion of water is removed from the formed web during passage of the formed web through the press.  A dryer is disposed downstream relative to the press for drying the pressed web such that a second portion of water is removed from the pressed web during passage of the pressed web through the dryer.  A further press is disposed downstream relative to the dryer for further pressing the dried web such that a third portion of water is removed from the dried web.  The further press includes a heated backing roll and an elongate press member which cooperates with the backing roll for defining therebetween an elongate pressing section for the passage therethrough of the dried web.  The dried web is subjected to increased pressure and temperature for an extended period during passage through the pressing section so that water vapor is generated within the pressing section for urging the third portion of water in the liquid phase away from the web, thereby inhibiting delamination of the further pressed web.

Title: Radiation/ultrasound interaction as optical shield protecting photosensors from laser beam attacks or during nuclear blast
Inventor: HOLUBOWICZ KAZIMIERZ S
IPC: G02F1/11
Filed: 1991-08-02
Abstract: RADIATION/ULTRASOUND   INTERACTION AS  OPTICAL  SHIELD   WHICH  OTECTS PHOTOSENSORS FROM LASER BEAM ATTACKS OR DURING NUCLEAR        BLAST               ABSTRACT OF THE DISCLOSURE           An   optical   shield  based  on   radiation/ultrasound interaction is disclosed.  The apparatus utilizes an acoustically tuneable light filter, which also works as a shutter when lack of acoustic   signal.   The   acoustically  tuneable  light   filter manipulates  band's  selection  to incident  upon  the  mentioned photosensor.  The  optical  shield based on  radiation/ultrasound interaction   prevents   photosensors  of  target  devices   from overexposure  to soft and hard radiation such as  X-rays,  alpha, betta,  gamma  or  the  like making the mentioned  target device operational  even though a high energy laser pulse  attacks.  The target  device  is protected to such a degree that it can  be  in operation  during nuclear blast.  It is so because the  mentioned shield analyses the incident radiation,  detects unsafe bands and after then it is only tunned to those bands detected as safe. The apparatus  works as  shutter too,  so when lack of safe bands it shuts the radiation off the mentioned photosensor.

IPC: H04L9/06
Filed: 1990-03-14
Abstract: The round number (R) is set to zero (100), then the round number (R) is incremented by one (102). The plaintext data (104) is subjected to a variable permutation (106). An entry is selected from the permutation table memory (108) and a value is selected from the Mask table memory (110) to conduct the variable permutation (10b).      Then, a choice component (C) is equated with round number (R).      Next, a first variable key addition operation (114) is carried out on the data employing a key from the key table memory (116) and a value from the Mask table memory (110). In the next step (118), the choice component (C) is see to a value one greater than the round number (R). The following step (120) determines if choice component (C) is equal to 11. If the choice component (C) is equal to 11, then the choice component (C) is set equal to 1 and another variable key addition is performed (122). Otherwise, a variable key addition is performed immediately (122).

Abstract: Abstract Transmitting Station for a Position Locating System, Particularly for the Microwave Landing System, and Methods for Monitoring and Controlling such a Transmitting Station A transmitting station for a position locating system and methods for monitoring and controlling it such a station are disclosed.            In known stations, the main equipment and the standby equipment operate alternately, and the monitoring consists in checking the transmitted signal received from external sensors.            It is object of the present invention to monitor at least the standby equipment during inactivity periods, i.e. while no signal are transmitted.           This is achieved through: -  use of external sensors (FS, MF) for monitoring both the main transmitter (TXM) and the main timing and control section (TCS1) during transmission periods, -  use of a dummy load (DL) and an internal sensor (IS) for monitoring the standby transmitter (TXR) during non-transmission periods, -  use of internal monitoring information (MI) for monitoring the reserve timing and control section (TCS2) and the electronic antenna (EA), and -  mutual monitoring of the two monitor sections (MS1, MS2 contained in the monitor unit (MU).

Title: Face plate
Inventor: STEWART IAN
IPC: F16B43/00
Filed: 1992-08-12
Abstract: ABSTRACT         A generally square face plate (1) for use with a 16 mm threaded rockbolt (2) includes a centrally located generally hemispherical raised portion (3), top surface (4) and a curved engagement surface (5) for abutting an excavated surface into which a rockbolt is to be installed.  An aperture (6) is centrally disposed in portion (3) for receiving the threaded end of rockbolt (2) for allowing tensioning of the rockbolt.       A circumferential corrugation (10) is adjacent to and surrounds portion (3).  Four radially corrugations (11, 12, 13, 14) extend from portions (3), through corrugation (10), two respective corners (15, 16, 17, 18) of plate (1).  The corrugations co-operate to allow plate (1) to be effective when used on uneven surfaces, as the plate will progressively deform to accommodate the surface contour and increase the area of contact between plate (1) and the excavated surface.  During any subsequent movement of rock restrained by rockbolt (2), face plate (1) will continue to compensate for changes in rockbolt tension.
