Patent CA-2074579-C (CA)
Title: Vacuum cleaner
Inventor: LIM MOO-SEANG
IPC: A47L9/22
Filed: 1992-07-23
Granted: 2000-01-18
Abstract: A vacuum cleaner with the noise greatly reduced is disclosed.   The vacuum cleaner includes a blower assembly which comprises: a vibration absorbing means for absorbing the vibrations occurring due to the high speed revolutions of electric blower 1; a noise shielding means for shielding the noise so as for the noise from the electric blower not to be propagated to the outside; a flow path changing means for curving and extending the flow path by banding the flow path of the air after passing through the electric blower; and a noise absorbing means for suppressing the noise by absorbing the noise propagated through the flow path. The vacuum cleaner of the present invention further includes blower assembly receiving section 41, which finally shields and absorbs the noise. Further, a vibration absorbing means is installed on the contact portion between the vacuum cleaner main body and the blower assembly, and air suction hole 48 is farmed on partition wall 44 which separates the dust collecting room and the blower receiving room from each other, so that the noise generated by the electric blower should be shielded without giving any increased resistance to the flow of air.

Title: Coke oven repair
Inventor: KOLVEK ROBERT E
IPC: C10B29/02
Filed: 1992-07-28
Granted: 2006-07-25
Abstract: A large size cast monolithic refractory module having high dimensional stability, good compressive loading, and good thermal shock resistance in the range of -20° to 1565° Celsius, which module may be used in the repair of the coke oven, and also a process for making such a large size cast module. The large size cast module should be of a size sufficiently large that it can replace all those silica bricks used in a course of bricks to enclose a single flue in a heating wall of a coke oven. A minimum size has a width of at least 35 centimetres, a height of at least 13.5 centimetres, and a length of at least 35 centimetres. The process for making such a module includes the steps of selecting a material which when cast will have the desired characteristics, mixing the dry refractory material with a relatively small amount of water, pouring it into a mold on a shaker table and vibrating the mold when filled, and then by firing the cast material after initial set at progressively higher temperatures up to 425° Celsius over a period of almost 60 hours.

Title: Dual chamber water filter
Inventor: MEEHAN ANTHONY B
IPC: B01D24/02
Filed: 1991-02-11
Granted: 1998-12-08
Abstract: A liquid filter (11) has a housing (13) with a bottom and a top (17). A vertical partition (27) divides the housing into an inlet chamber (29) on one side and outlet chamber (43) on the other side. One type of filtration material is located in the inlet chamber. Another type is located in the outlet chamber. The inlet to the inlet chamber is located in the bottom of the housing and results in an upward flow through the inlet chamber. The outlet chamber has an outlet located in the bottom. A port (41) locates at the top of the partition. This results in a downward flow through the outlet chamber.

Title: Novel bioprocesses for preparing 7-aca and 7-adac
Inventor: CONDER MICHAEL J
IPC: C12N15/09
Filed: 1992-10-14
Granted: 2004-01-06
Abstract: Important intermediates for preparing cephalosporin antibiotics, 7-amino-cephalosporanic acid (7-ACA) and 7-aminodeacetylcephalosporanic acid (7-ADAC), are prepared by a novel bioprocess in which a transformed Penicillium chrysogenum strain is cultured in the presence of an adipate feedstock to produce adipoyl-6-APA (6-amino penicillanic acid); followed by the in situ expression of the following genes with which the P. chrysogenum has been transformed: 1) an expandase gene, e.g., from Cephalosporium acremonium, whose expression product converts the adipoyl-6-APA by ring expansion to adipoyl-7-ADCA; 2) an hydroxylase gene whose expression product converts the 3-methyl side chain of adipoyl-7-ADCA to 3-hydroxymethyl, to give the first product, 7-aminodeacetylcephalosporanic acid (7-ADAC); and 3) an acetyltransferase gene whose expression product converts the 3-hydroxymethyl side chain to the 3-acetyloxymethyl side chain of 7-ACA.      The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.

Title: Reduced calorie cocoa butter substitutes
Inventor: COOPER CHARLES F
IPC: A23D9/013
Filed: 1993-11-17
Granted: 2001-10-23
Abstract: Esterified propoxylated glycerin compositions containing acyl groups derived from C12-C24 saturated linear fatty acids wherein at least 50 mole percent of the total acyl groups are derived from no more than two different such acids are useful as cocoa butter substitutes in the preparation of reduced calorie food products such as chocolate and other confectioneries. The cocoa butter substitutes closely mimic the desirable organoleptic properties of natural cocoa butter, yet do not require tempering or conching to achieve highly satisfactory mouthfeel and appearance, and may be conveniently and inexpensively prepared using readily available starting materials.  The use of the substitutes in chocolate formulations provides products having excellent firmness, "snap", and resistance to deformation and surface marking during normal handling prior to consumption.

Abstract: Refuse 21 in a refuse container Z is heated by a heater 16, and the steam generated from the refuse 21 is condensed by a condenser 8. The ambient temperature near the refuse container 2 is detected by a first temperature detector 6, and the output of the heater 16 is controlled by the output of the first temperature detector 6 so that the temperature near the refuse container 2 may be a specific temperature, and the temperature of the steam flowing out from the refuse container 2 into the condenser 8 is detected by a second temperature detector 7 at the condenser 8. When the temperature change of the second temperature detector 7 exceeds a specific value, the drying process is terminated, so that the drying end time can be detected accurately without allowing to scorch.

Title: Papermakers fabric with orthogonal machine direction yarn seaming loops
Inventor: LEE HENRY J
IPC: D21F7/08
Filed: 1994-08-19
Granted: 1998-04-28
Abstract: A flat woven pin-seamed papermakers fabric wherein machine direction yarns define a series of seaming loops on the opposing fabric ends.  The fabric comprises a system of flat monofilament machine direction warp yarns (hereinafter MD yarns) which are woven  in  a  selected  weave  construction.    In  a preferred embodiment,  the system of MD yarns comprises upper and lower yarns which are vertically stacked.  Selected end segments of the upper and lower MD yarns are removed and yarn segments made of a more durable material are rewoven into the fabric end in the space vacated by the  trimmed upper and lower MD yarn end segments.    Non-loop  forming upper MD yarns  are  preferably backwoven into the space vacated by trimming respective lower MD yarns.   Preferably,  at least the upper MD yarns are   woven contiguous with each other to lock in the machine direction alignment of the stacking pairs of MD yarns and the orthogonal orientation of the end loops.  The seaming loops of the opposing ends  are  intermeshed  and  joined via  a pintle  yarn.    The permeability of the seam area is controlled via the inserting of rectangular stuffer yarns parallel to the pintle yarn.

Abstract: A V-bar suspension linkage is shown and described. In a preferred embodiment, two arms are mounted between the axle and the vehicle frame rails, the arms extending outwardly at an angle to each other to form a "V" shaped linkage, having its vertex at the axle.  The first end of each arm is coupled to the axle via a vertically oriented bushing pin that is secured to an axle bracket which in turn is mounted on the axle.  By vertically mounting the bushing pins, the ends of the arms may be closer together, thereby increasing the angle between the arms and reducing  the stresses in the arms and bushings.  The distal end of each arm is coupled to a frame rail via a vertically oriented bushing pin that is secured in place by anchor lugs that are provided on upper and lower gussets that form part of the vehicle frame assembly.  The pitch and lateral placement of the axle is easily adjusted at the axle via use of spacers between the axle bracket and bushing pins.
