Patent CA-2042811-A1 (CA)
Title: Method for manufacturing nails
Inventor: LAT GERONIMO E
IPC: F16B15/08
Filed: 1991-05-17
Abstract: Nails suitable for outdoor use, such as roofing nails, are formed from carbon steel wire pre-coated with a metallic layer, which has corrosion-resistant properties, such as a zinc layer applied by pre-galvanizing the wire.  Each nail is formed with a shank and with a head.  The metallic layer is discontinuous in a region on the head of each nail.  The nails are collated by means of collating wires welded to the shanks of the nails.  The collated nails are coiled. The coiled nails are cleaned in a cleaning bath, such as 1,1,trichloroethane.  The cleaned nails are coated with a polymeric layer, which covers the region on the head of each nail where the metallic layer is discontinuous, thus restoring the corrosion-resistant properties of the nails.

Title: Molten metal pump with filter
Inventor: AMRA LUTFI
IPC: F04B39/16
Filed: 1991-06-14
Abstract: MOLTEN METAL PUMP WITH FILTER                         Abstract A molten metal pump includes a filter that prevents ingestion of foreign material such as dross from molten metal within which the pump is immersed.  The filter is a large structure that is secured to the base of the pump surrounding the pump's inlet.  The filter forms a cavity adjacent the pump's inlet.  The ratio of the surface area of the filter to the inlet area of the pump is very large due in part to a corrugated end wall included as part of the filter.   The filter has a low porosity while maintaining a high flow rate for the pump. In an alternative embodiment,  the  filter  is  a  semi-toroidal  structure  that  is attachable to a pump base having an upper inlet.   The filter surrounds the pump's inlet.  The filter includes a central opening through which access can be had to the pump's impeller for purposes of  inspection,  repair,  or  replacement without disturbing the attachment between the filter and base.

Abstract: Abstract of the Disclosure An integrated head/flexure/conductor structure (20) for the reading and writing of information with respect to a relatively moving medium (32), such as a disk or drum, and a method for manufacturing the same. The proposed structure (20) takes the form of a micro-dimension, elongate, dielectric flexure body (34), and embedded within such body both magnetic read/write pole structure (22; 44, 46), and electrical coil and conductor structure (36, 38, 40, 42; 56) operatively associated with the pole structure (22; 44, 46). The flexure body (4) and the embedded constituents are formed on an atom-by-atom basis utilizing one or more conventional material-deposition processes. The method proposed by the invention includes orthogonal-plane processing steps that facilitate formation of the magnetic pole structure (22; 44, 46) in a way enhancing dimensional control. In addition, the method of the invention involves steps utilizing etchable wall-like stripes (66), and a commonly etchable base layer (64), which together define three sides of the structure of the invention during formation thereof, etching of which stripes (66) and layer (64) greatly facilitates separation and release of finally completed units as free individuals.

Title: Sustained release formulations
Inventor: MUHAMMAD NOUMAN
IPC: A61K9/52
Filed: 1991-07-25
Abstract: Abstract Semi-enteric controlled release formulations are comprised of a biological active agent such as an antibiotic that is blended with a water-soluble bulking agent, the mix then coated onto an inert core.  The coated active core is further coated with a mixture comprised of an acrylic copolymer, bulking agent and pH dependent food acid.  These different coating components possess different solubility characteristics which result in a gradual release of the active in both the stomach and small intestine that provides an increased bioavailability of the active drug.

Title: Process for the preparation of mtbe
Inventor: SMITH LAWRENCE A JR
IPC: C07C41/06
Filed: 1991-11-05
Abstract: ABSTRACT OF THE DISCLOSURE    A process is provided   for etherification of essentially pure iC4= with MeOH to form MTBE in a distillation column reactor containing a mixed bed acid cation exchange resin as a catalytic distillation structure in an a distillation reaction zone.   An inert C4 hydrocarbon is initially fed to the distillation column reactor to act as a diluent and a heat sink which boils at the desired temperature range for the reaction.   Additionally the inert C4 diluent acts as an azeotroping agent for the MeOH in the lower end of the column carrying more of the MeOH back up into the reaction distillation zone. After start up and circulation the inert C4 hydrocarbon feed is stopped and that in the system is  retained  therein  by  total  reflux  of  the  overheads  and judicious  operation of the  lower portion of the distillation column reactor.            \crl.pat\1227.app

Title: Method of prevention of adhesion of hot-mix asphalt to containers and equipment
Inventor: BALLENGER WILLIAM T JR
IPC: B05D5/08
Filed: 1992-02-11
Abstract: An improved method of prevention of adhesion of hot-mix asphalt to dump trucks and other containers or equipment comprises preparing an aqueous dispersion of a vegetable oil and applying the dispersion to the surface of the container before loading the hot-mix asphalt therein. Vegetable oils which are useful as release agents in aqueous dispersion include cottonseed oil, soya oil, rate (canola) oil, peanut oil, corn oil, sunflower oil, palm oil, coconut oil and palm kernel oil. The oil is emulsified in water, using a suitable emulsifier, preferably a sorbitol base emulsifier, in the amount of 1 - 5 oz. per gallon of water. The oil and emulsifier are preferably premixed and supplied as a self-emulsifiable composition. The resulting emulsion is applied in an amount to provide a thin coating on the wall of the container or equipment. The emulsion is applied in the amount of 3 - 4 qts. to coat a dump truck or 4 - 6 qts. to coat a trailer. The hot-mix asphalt is easily removed from the container, i.e. truck or trailer, or other equipment without sticking and the release agent has been found to be completely biodegradable.

Filed: 1992-03-04
Abstract: ABSTRACT In effecting an end-to-end fusion splice between two optical fibres, the optical fibres are introduced into opposite ends of two support members so that parts of the optical fibres protrude from the members.  The fibres are secured in the members and the protruding parts are cut to form tails of predetermined lengths. The support members are then arranged in axial alignment and one is caused to move axially towards the other until the end faces of the protruding tails are spaced a predetermined distance apart.  Fusion splicing is then effected, the support members are permanently secured together and mechanical protection for the fusion splice is provided.

Abstract: Abstract of the Disclosure An expansion and contraction type guard baton causing less rattling or deviation even after repeating use and free from the worry of slipping off by the force of thrusting and extending the baton main body even if the wall thickness is decreased to reduced the weight.  A plurality of cylin-drical members are combined in a telescopic manner in which the conically inclined surface at the top end of an outer cylindrical member and a conically inclined surface at the rear end of an inner cylindrical member are engaged for preventing slip-off upon extension.  The circumferen-tial cylindrical slide guide surface in parallel with the cylindrical axis formed before and after the conically inclined surface and the cylindrical member are put to a plane-to-plane contact, thereby preventing rattling or deviation.  Further, the wall thickness at the top end of the outer surface of the outer cylindrical member is increased to prevent slip-off.
