Patent CA-2082512-A1 (CA)
Inventor: MURAMATSU MOTOHIKO
IPC: A24D1/02
Filed: 1992-03-09
Abstract: The vented filter cigarette is produced by combin-ing a filter having a highly air-permeable circum-ferential surface and a tipping paper having a plurality of pores.  The tipping paper has an embossment in the area of the pores formed therein.  The embossment serves to create a slight gap between the tipping paper and the circumferential surface of the filter, by which the tightness therebetween is loosened.  Thus, the filter ventilation is increased, and the variation in the degree of the ventilation can be reduced.
Patent CA-2082977-A1 (CA)
Title: Injection molding machine
Inventor: HEHL KARL
IPC: B29C45/07
Filed: 1992-11-16
Abstract: An injection molding machine comprises a carrier block, which contains a plasticizing cylinder and to which hydraulic advance-retract cylinders and hydraulic injecting cylinders are axially coupled. The cylinder barrel of each advance-retract cylinder carries an injecting piston for cooperating with an injecting cylinder barrel which surrounds the advance-retract cylinder barrel. Because each advance-retract cylinder barrel is integrally formed with a radial flange, which constitutes the injecting piston for cooperating with the associated injecting cylinder barrel, the injecting unit will be able to withstand high pressures and its parts can yet economically be made in series.
Patent CA-2084709-A1 (CA)
Inventor: WILLIAMS DANNY L
IPC: A23K10/33
Filed: 1992-12-07
Abstract: Ruminant animals, as herbivores, survive and produce while feeding chiefly on grass or other roughage consisting of large amounts of cellulose   Ruminants which have been consuming primarily diets high in cellulose must gradually be adjusted to high grain rations.  When the attempt is made to adapt and feed ruminants diets containing no roughage, metabolic problems surface.  The increase in lactic acid and accompanying fall in rumen pH resulting from roughage or cellulose withdrawal leads not only to the destruction of cellulolytic bacteria which digest cellulose), but to the destruction of lactate utilizing organisms, resulting in acidosis and its attendant adverse effects, which results in less than optimal cattle performance.  Herein roughage can be eliminated allowing ruminants to consume an all grain, properly balanced diet without these adverse reactions.  A roughage free diet for ruminants is provided which alters the eating behavior of cattle.  The diet incorporates ingredients which modify feed consumption patterns of cattle consuming a roughage free diet.

Patent CA-2089688-A1 (CA)
Inventor: BATTEN RONALD W
IPC: B25B15/00
Filed: 1993-02-17
Abstract: ABSTRACT         There is disclosed a direct acting lock mechanism to secure a tool within a driver which is useful for securing open channel sockets used to securing aerospace fasteners in a driver.   These sockets have a flatted shank,  typically hexagonal in cross section,  and are received in a socket receptacle of the driver which has a cross section matching that of the shank.  In the preferred embodiment, the flatted surfaces  of  the  shank are  formed  to have  substantially coextensive flats which are displaced through an angular increment of at least about 15 degrees.   The flats do not extend the entire length of the shank, however, thus providing a thin shelf which has a cross section which matches the internal flatted surface of the socket receptacle of the driver.   The driver has an annular internal groove on the inside wall of its socket receptacle and that groove is located at an intermediate height in the socket receptacle to align with the thin shelf of the shank when the socket shank is placed in the socket receptacle of the driver.  The shank of the tool is received in the driver receptacle with the shelf received in the groove and locks in the tool upon a slight degree of rotation.

Inventor: LUEBKE ROGER D
IPC: B66C13/06
Filed: 1993-03-26
Abstract: An overhead crane apparatus including a hoist supported on a trolley.  The hoist includes a bottom block with a pair of horizontally extending first and second trunnions.  The overhead crane apparatus also includes an automatic mechanism for releasably securing the bottom block to the trolley.  The mechanism includes first and second bottom block support plates having therein respective first and second downwardly opening notches.  The mechanism also includes first and second hooks and fluid actuated cylinder/piston assemblies for biasing the hooks toward latched positions wherein the hooks overlap the first and second notches, respectively.  When the bottom block is raised the first and second trunnions enter the associated first and second notches and cam the hooks to unlatched positions responsive to movement of the bottom block to a secured position. The hooks then return to their latched positions to prevent the trunnions from moving downwardly out of the notches to thereby secure the bottom block.

Title: Overbased phenate process
Inventor: CHANG YUEHSIUNG
IPC: C07C323/20
Filed: 1993-11-23
Abstract: OVERBASED PHENATE PROCESS               Abstract of the Disclosure Overbased sulfurized alkaline earth metal alkylphenate having excellent water tolerance properties in lubricant formulations is prepared by charging into a reactor a pre-heated (280-380°F) mixture of alkaline earth metal base and alkylphenol (preferably in oil), while simultaneously, but separately, charging a promoter solvent such as a glycol. Then a controlled amount of molten sulfur is charged at a rate that controls the reaction exotherm and off-gas evolu-tion, while maintaining the 280-380°F temperature.  Upon completing the sulfur charge, the reactor contents are al-lowed to interact at 280-380°F long enough to form the sul-furized alkylphenate.  While keeping the temperature at 280-380°F, the sulfurized alkylphenate is overbased by charging the reactor simultaneously with controlled amounts of al-kaline earth metal base, promoter solvent, and carbon diox-ide gas, at a controlled charge rate not much greater or less than the rate at which the reactants undergo reaction to form the overbased phenate.  Upon completing the charging of the alkaline earth metal base and promoter solvent, the carbon dioxide charge is continued until completion of the carbonation reaction.  Unreacted alkylphenol and promoter solvent are stripped off under vacuum with inert gas purge at 400-480°F, and the resultant reaction product is filtered and the filtered product recovered.  The reaction cycle time is no more than about 6 hours, and the filtered product has water tolerance properties normally associated with a batch preparation of the same product requiring a reaction cycle time of at least 8 hours.
Patent CA-2110802-A1 (CA)
Title: Non-contaminating probe
Inventor: FELIZIANI ROBERTO
IPC: A61M25/01
Filed: 1992-06-05
Abstract: A non-contaminating cather includes a generally hollow tube (12) having an axial lumen extending along the length thereof, and an elongated, tubular elastic membrane (14) disposed within the lumen. As the catheter is inserted into a patient, the membrane (14) is drawn through the tube and out the leading edge of the tube.  Once the catheter is fulled inserted, the membrane circumscribes the tube; thus, contact between the tube and the patient is substantially, if not entirely, prevented during insertion of the cather. More particularly, the membrane is laid out as the catheter is urged along the anatomical canal and thus remains interposed between the exterior wall of the catheter and the patient's internal organs (e.g, the urethra). Sliding frictional contact between the catheter tube and the urethral mucosa is inhibited and the passive transportation of pathogens in the lower urinary tract concomitantly prevented.
