Patent CA-2033296-A1 (CA)
Inventor: JUSUFBEGOVIC SUKRIJA
IPC: C25C3/12
Filed: 1990-12-27
Abstract: ABSTRACT        Title:     Plug for sealing the recesses for anode rods in anode blocks during the calcination process The subject is a plug 1 for sealing the recesses 2, which are designed to hold anode rods in anode blocks 3, wherein said anode blocks 3 are intended for the electrolytic extraction of base metals during their calcination treatment.  The proposed plug 1 is characterized by the fact that it is die-formed and composed of material containing cellulose. This provides a very close seal for anode openings 2.  Coke granules, which are inserted as fill material to displace oxygen in gaps between the several anode blocks 3 within a calcining furnace, cannot enter said anode openings 2.  Undesirable conglutination inside said anode openings 2 and burning of the anode openings 3 (sic), causes by the unavoidable presence of some oxygen residue during the calcination process, can no longer occur.  Because of the great solidity of said plug 1, deformatious of said recesses 2 in the lower rows of anode blocks 3 in the calcining furnace are prevented.  At the conclusion of the calcination process, after said anode openings 2 are precipitation-hardened, the cellulose containing plugs 1 are carbonized, whereby the coal or ashes remaining in said recesses 2 can be removed by vacuuming without any difficulty in a subsequent operation.

Patent CA-2034752-A1 (CA)
Inventor: LOK YUK L
IPC: F24C3/08
Filed: 1991-01-22
Abstract: A stove suitable for large-burner cooking generating a high heat exhaust has an enclosed stove casing with an upper cooking surface, a hollow interior, and a burner well recessed into the interior of the casing.  A large burner is positioned in the burner well, and a cooking vessel can be placed over the well so as to close the burner flame off from the outside.  The burner well preferably supports a wok or other rounded-bottom cooking vessel.  The high heat exhaust from the burner is trapped in the well and entrained by natural convection into a duct member to a duct casing at a rear side of the stove.  The duct casing has a double wall construction and baffles in its interior forming a labyrinthine  channel  for  mixing  cold  air  supplied  through openings in the stove casing and the hot exhaust air from the large  burner.    The  stove  includes  a  catch  basin  member positionable in the interior of the burner well for catching any spillage or debris.  The stove casing has a window formed in its front panel for allowing the stove user to visually check the burner flame.  Further features include a recessed burner plate positionable in the well over the burner for allowing cooking with other types of cooking vessels, and a grill positionable over the annular rim of the stove and a deflector unit below for open-flame cooking when the wok is not used.

Title: Intermediate drive shaft support utilizing a standard bearing
Inventor: MARCH GARY L
IPC: F16C33/76
Filed: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE    An intermediate bearing support for a drive shaft of a vehicle is required when three or more universal joints are embodied in a driveline between a transmission and a differential Special bearings of particular dimensions and having wider inner races than outer race have heretofore been employed for this particular application.  Such bearings are substantially more costly than standard ones.  The new drive shaft support uses standard bearings with special adapter components for use with the supports.  The adapter components include special adapter rings located between the inner race of the bearing and the shaft being supported.  In most instances, adapter rings are also located around the outer race between the outer race and a grease retainer and rubber mounting block of the support.

Abstract: Method and device in the manufacture of paper or board for dewatering of a paper web that is being manufactured.  The paper web is transferred from a forming wire onto a wire in the drying section while constantly on support of a fabric that receives water, a transfer fabric, or of any other, corresponding transfer surface as a closed draw, at a particularly high speed, which is higher than about 25-30 m/s.  Dewatering of the paper web is carried out by means of at least two subsequent press nips, of which nips at least one press nip is a so-called extended-nip zone, whose length in a machine direction is larger than about 100 mm.  The extended-nip zone is formed in connection with a mobile flexible press-band loop.  The distribution of the compression pressure employed within said extended-nip press zone is regulated and/or selected both in the transverse direction of the web and in the machine direction so as to set or to control the different profiles of properties of the web.

Abstract: The present invention relates to a method for finely-grinding minerals and similar material intended for use as filler material to a particle size appropriate for this purpose, with the aid of a mill which operates with agitated grinding medium and in which the material is ground in a substantially dry state. The invention is characterized by predetermining the stay time of the material being ground in the mill; maintaining the predetermined stay time partly by discharging ground material from the mill at a predetermined, essentially constant rate, and partly by adjusting the infeed of material to the mill in relation to the quantity of material discharged from the mill such that the amount of material present in the mill increases during the infeed of material thereto; and by interrupting the infeed of material to the mill over a predetermined short period of time when the material reaches a prede-termined highest level in said mill.          The invention also relates to an arrangement for carry-ing out the method. This arrangement is characterized in that it includes a first motor-driven device which functions to control the infeed of material, a mill for grinding with the aid of an agitated grinding medium, a perforated disc which functions to separate grinding medium from the ground material leaving the mill, a second motor-driven device which functions to maintain a substantially constant outfeed of ground material from the mill, and a level monitor which is mounted in the upper part of the mill and connected to the motor-driven infeed device.

Title: Construction system consisting of moulded bricks and light supporting frameworks
Inventor: WERNER HILMAR
IPC: E04B2/46
Filed: 1990-06-19
Abstract: A construction system consisting of moulded bricks and light supporting frameworks is useful for constructing ecological building contructions, in particular with wide spans between supports.  This construction system is suitable for industrial prefabrication of individually dimensioned wall elements made from hollow, load-bearing, sand-lime bricks which can be prestacked when dry by a CNC-controlled robot and assembled later either in a factory or on site by unskilled workers, for example handymen; wall sections measuring several square metres can be erected using a single lifting accessory. The bricks are then filled with reinforcements, fittings and concrete, plaster, lime, etc. In particular, internal walls can be fitted with heating and cooling pipes, and external walls with absorber pipes. Wall and foundation elements are used as radiant heating surfaces and/or storage masses. The light supporting frames consist of sheet metal stiffened along a plurality of axes and/or trellis work, in particular of machine-welded structural steel. The invention also concerns joining means forjoining the components, and devices for manufacturing them. The construction system utilizes ecological building materials in a manner which is time and labour saving and involves little material and financial outlay.

Title: Method and apparatus for correcting mwd porosity measurement
Inventor: MAKI VOLDI E JR
IPC: E21B47/00
Filed: 1992-06-17
Abstract: ABSTRACT OF THE DISCLOSURE             A porosity measuring MWD system utilizing a source and two detectors is set forth. The source and two detectors are preferably mounted in a stabilizer fin on a drill collar. A standoff measuring device is also included. Dependent on dynamically measured standoff, output pulses from the two detectors are input to storage counters; different counters are selected for different ranges of standoff. Porosity measurements are determined from the counts for variations in standoff measurements; this provides a near/far ratio for ranges of standoff; as the standoff range varies, the counts are directed to different counters. Near/far ratios are determined and represent the apparent porosity; a corrected value of porosity is then determined for each particular range of standoff.
