Patent CA-2092308-A1 (CA)
Inventor: ARTERBURY BRYANT A
IPC: B22F5/12
Filed: 1991-10-03
Abstract: A tubular sand screen is made in one piece entirely of powdered metal slivers which are molded and sintered to form a metallurgically integral rigid tubular structure.    Aggregate  metal  particles,  for  example, stainless steel slivers, are bonded together by interatomic diffusion as a result of sintering the compacted slivers under  high  temperature  and  pressure  conditions.    The sintered metal sand screen performs the function of a conventional  prepack  assembly  as  well  as  the  screen function.  According to one aspect of the invention, the sintered metal screen is subjected to electropolishing to yield an effective porosity of  40-60 mesh,  with pores having an average pore size of 150 microns.  Most of the surface irregularities are removed by electropolishing, and very few nucleation sites remain where sand fines in the size range of 74 microns-100 microns can become captured or otherwise lodged to cause plugging of the screen.

Abstract: La présente invention vise un appareil mécanique servant à visser et à dévisser les joints d'une tige de forage, comportant un cylindre de serrage (24) à déplacement en sens unique, conçu pour visser et dévisser les raccords de tiges. Le cylindre est du type à trois mâchoires (21, 22, 23), les mâchoires supérieure et inférieure (21, 23) étant identiques, et les trois étant reliées par un bâti commun. D'autres cylindres referment les mâchoires (36, 37) à chaque niveau. L'appareil se déplace dans le sens vertical. Une combinaison de deux mâchoires sert à visser les joints, et une autre combinaison de deux mâchoires sert à les dévisser. Des outils à came (66) spéciaux servent à retenir les tiges. Des dispositifs (94, 101) servent à repositionner la mâchoire médiane après chaque intervention sur des tiges de diamètres différents. Les mâchoires sont constituées de paliers, d'une articulation et de réglages spéciaux (66, 73). Elles fonctionnent dans un seul sens et sont autoserrantes.

Abstract: ABSTRACT OF THE DISCLOSURE           A tissue holder for use in a motor vehicle having a windshield and a ceiling, comprising an open tray for supporting a tissue box, a mounting bracket made of resi-lient material attached by one end to the open tray, and a suction cup fastener comprising at least one and preferably three  suction  cups,  attached to the  other  end of  the mounting bracket.  Two of the suction cups are attached to the upper side of the fastener and the third suction cup is attached to the lower side of the fastener. By properly fixing the suction cups onto the windshield of the vehicle, the  mounting  bracket  may  resiliently  conform  to  the windshield and the ceiling of the vehicle, and hold and support the open tray on the ceiling.  The structure of the holder  avoids making  perforations  in  mouldings  of  the ceiling or in the ceiling of the vehicle.
Patent CA-2094168-A1 (CA)
Title: Mufflers
Inventor: RAMJIT CARL N
IPC: F01N1/12
Filed: 1993-04-16
Abstract: A sound attentuating device, typically applied to the exhaust of internal combusion engines, and consisting of a helicoidal element fitted snugly within a tube. The helicoid is formed by a sequence of flat triangular sufaces generated by a forward fold transverse to a longitudinal axis followed by a reverse fold oblique to the longitudinal axis and having the procedure repeated. It is analogous to an accordion-like strip which rotates because an oblique fold alternates with a transverse fold. The muffler functions by having the helicoid reflect sound waves generated within the machine to which it is attached while permitting the escape of gases through the tube in a spiral manner.

Title: Electronic trip device comprising a correcting device
Inventor: TRIPODI PAUL
IPC: H02H3/093
Filed: 1993-05-11
Abstract: ABSTRACT            ELECTRONIC TRIP DEVICE COMPRISING A CORRECTING DEVICE   The trip device comprises an elactronic processing unit (7) which gives a tripping order (D) in terms of the rms value of the current measured (Im) by current transformers and of the threshold (S) and time delay (T) setpoints. The non linearity of response of the transformers is corrected by a device (9) which modifies the current, threshold, or time delay values. These corrected values (Ic, Tc and Sc) enable precise trippings to be achieved in compliance with the valuesof the current flowing in the circuit breaker. The type of correction is adapted to the circuit breaker rating by parameters (11), obtained by means of tests and previously stored in a device (10).            (Figure 3).

Title: Method and apparatus for oxidizing pulverous fuel with two gases having different oxygen contents
Inventor: KAASINEN PENTTI J
IPC: F27D99/00
Filed: 1993-05-28
Abstract: The  present  invention  relates  to  a  method  for oxidizing the pulverous fuel of a furnace, advantageously a flash smelting furnace, by means of a burner.  The oxidation takes place mainly owing to an effective mixing of two different combustion gases, pulverous fuel and an optional supplementary fuel in the furnace.  The combustion gases are conducted into the furnace in separate flows, so that oxygen is fed in through the center in an at least partly turbulent flow,  and air is fed around the oxygen flow in several separate flows.  The invention also relates to a burner for mixing and burning pulverous fuel and combustion gas in the furnace.

Title: Formation of stable liposomes from lipid extracts of archaeobacteria (archaea)
Inventor: SPROTT G DENNIS
IPC: C07H15/26
Filed: 1992-10-23
Abstract: Novel ether lipids were obtained from methanogenic (Methanospirillum hungatei, Methanococcus jannaschii, Methanococcus voltae.      Methanosarcina mazei, and Methanobrevibacter smithii), and extremely halophilic (Halobacterium cutirubrum) representatives of the archaeobacteria.    Several of the ether lipids produced by Methanospirillum and Methanosarcina genera were purified and characterized structurally for the first time.    Unilamellar liposomes were prepared from emulsions of the total polar-ether lipid extracts of such bacteria by pressure extrusion through membranes of various pore sizes. Liposome populations were shown by dynamic light scattering and electron microscopy to range in size depending on the pore size of the filter, on the source of the lipids, and on the composition of the suspending buffer medium. In all cases the size ranges indicated highly homogeneous preparations. Leakage of entrapped fluorescent or radioactive compounds established that the ether liposomes were stable to attack by phospholipase A2 and B, and were stable for at least 60 days to storage in an atmosphere of air. The detergent dialysis method of forming liposomes also produced unilamellar liposomes from most of the archaeobacterial total polar lipid extracts which were tested.
