Inventor: DUBLINSKI ALEX C
IPC: B29C33/76
Filed: 1993-12-07
Abstract: 2148470 9414600 PCTABScor01 A composite molding apparatus (10) and method for high pressure co-cure molding of lightweight honeycomb core composite articles having ramped surfaces utilizing low total density, stabilized ramped honeycomb cores. The low total density, stabilized ramped honeycomb core is formed by net shaping stabilized honeycomb core material into a ramped honeycomb core, which is prepped for lay-up and co-cure by applying a layer of low areal weight film adhesive to the upper, lower and ramped surfaces thereof. The honeycomb core material is stabilized for the net shaping operation by a layer of the low areal weight film adhesive applied to the upper and lower surfaces of the material in a predetermined picture frame format. The composite molding apparatus is a semi-rigid molding assembly that includes a rigid base member (12) and a complementary semi-rigid mold (20) member that includes internal rigid reinforcement inserts (22) that provide symmetric pressure distribution over the ramped surfaces of the honeycomb core and the overlaid composite prepregs during the high pressure co-cure process.  Composite prepregs and the ramped honeycomb core are laid-up in the semi-rigid molding assembly, which is vacuum bagged and disposed in an autoclave. The vacuum bag is evacuated, and the laid-up molding assembly is subjected to a two stage pressure, temperature cycle for high pressure co-cure. The autoclave is pressurized to a dwell pressure, and the temperature is then raised from ambient to a dwell temperature whereupon the autoclave is stabilized for a dwell period. Next, the autoclave pressure is increased to a high pressure, and the temperature is raised to a co-cure temperature whereupon the autoclave is stabilized for a co-cure period to effect curing of the lay-up. After curing is complete, the autoclave is cooled, and then depressurized for removal of the composite molding apparatus.

Title: Device changing purchase of block and tackle
Inventor: TAKOUBOVSKI ALEXANDRE
IPC: B63H9/10
Filed: 1995-06-27
Abstract: This invention can be used to construct multipurchase block system. Purchase of the system increases as the distance between objects, connected with the system, decreases and vice versa.          The purchase increases in one or more steps, depends on number of devices used.  Sailboats and other sail driven apparatuses often use blocks to trim sails. The disadvantage of traditional block and tackle is constant mechanical advance also called purchase whereas the pulling strength exerted on sheets differs from one point of sail to another. At the same absolute wind velocity, the tension on sheets become greater as the boat goes closer to the wind.          This invention compensates for the increasing tension by automaticaly engaging additional sheaves in work when the sail is trimmed closer a certain point and disengage the sheaves on the way back thus changes purchase of block and tackle according to the trim of sail. The point of engaging/disengaging can be adjustable or preset. These devices may find their use on small to medium size sailboats especialy those with no winches.

Title: A phosphor coating arrangement for an electrodeless discharge lamp
Inventor: ROWLEY ANDREW TERRENCE
IPC: H01J65/04
Filed: 1995-04-06
Abstract: An electrodeless discharge lamp (10) having a lamp envelope (12) containing a fill of mercury and a rare gas is excitable to a discharge state by introduction of RF energy in close proximity thereto. A ballast circuit contained within the housing base portion (22) of the lamp is effective for generating the RF energy from conventional line power. The ballast circuit includes a core portion which extends within a re-entrant cavity (16) formed within the lamp envelope. During operation of the lamp, the re-entrant cavity portion is exposed to higher wall loading conditions than is the outer surface of the lamp envelope. These higher wall loading conditions require the use of comparatively more expensive rare earth phosphors (30) at the re-entrant cavity portion than are needed on the outer portion of the lamp envelope where it would be appropriate to utilize conventional halophosphate materials (32). In order to provide for two distinct phosphor coating materials in a single lamp envelope configuration and at a reasonable cost, such phosphor coating is done by coating the re-entrant cavity and the outer portion separately and then joining these components together to produce the finished lamp envelope. The juncture point between the re-entrant portion and the outer envelope portion resides under an upper rim portion of the housing and is therefore not visible in the end lamp product.

Title: Ethylene conversion process
Inventor: MAUNDERS BARRY MARTIN
IPC: C07C11/02
Filed: 1995-11-23
Abstract: This invention relates to a process for converting ethylene to a mixture of 1-olefins by (a) feeding ethylene through an oligomerization catalyst bed to form an oligomer  predominating in C2-C6  olefins and (b) feeding the oligomer, optionally admixed with fresh  ethylene, containing at least 50 % by volume ethylene, through a metathesis catalyst bed to form a product predominating in C2-C6 1-olefins.  Steps (a) and (b) can be carried out sequentially and in a single reactor under the same conditions of reaction temperature and pressure. This mitigates the perceived disadvantages of low activity and low conversions of relatively inexpensive oligomerization  catalysts and forms oligomer having the desired distribution of 1-olefin components for use as comonomer in a polyolefin process.

Title: Method for manufacturing coated feed pellets
Inventor: VIS WILLIAM H
IPC: A23K40/30
Filed: 1996-08-26
Abstract: A method of manufacturing coated feed pellets comprises wetting the feed pellets with a mist of unheated water and then enclosing the wet feed pellets in a coating material. The feed pellets are initially separated by a rotating disk and then passed through a mist of unheated water generated by dripping water onto a concave disk rotating in the opposite direction of the first rotating disk. The wet feed pellets are then enclosed in a mixture comprising of a mixture of milk sugars, icing sugars and flavors. This coating material not only increases the palatability of the feed pellet, it also crystalizes upon drying, thereby forming a protective casing around the feed pellet. This prevents breakdown of the feed pellet during shipping and handling. As a consequence, feed pellets with a fat content that is higher than currently possible can be manufactured.

Patent CA-2185722-A1 (CA)
Title: Apparatus and method for controlling a construction machine
Inventor: TOZAWA SHOJI
IPC: E02F3/43
Filed: 1996-09-16
Abstract: The finishing precision and uniformity of hardness of a surface finished by a construction machine, such as back-hoe, is improved by modifying the targets of a position-tracking control system based on work-load applied to the end effector of the construction machine. For example, compaction force of a surface, contoured by a position-tracking back-hoe, can be made more uniform. This is accomplished by adjusting actuator targets, otherwise controlled on the basis of positional and speed constraints, in response to a detected work load acting on the end effector. To detect work load, a hydraulic fluid pressure signal can be applied to a computer which generates target position and speed commands to the feedback system. The control circuit may be arranged to hold work load constant (generating a constant compaction force for example) or, in response to a priority signal, the circuit can give a selected weight to both the positional constraints and the work load constraints. Another benefit of altering position-tracking in response to work load is improved coordination of actuators. For example, the gain of feedback and feedforward signals of a position-tracking control system can be increased when a detected load is heavy, increasing response, and attenuated when the load is light.?
