Patent CA-2322351-A1 (CA)
Title: Electrical connector assemblies
Inventor: PARRY IAN CHARLES
IPC: H01R13/426
Filed: 2000-10-05
Abstract: Electrical busbar terminal assemblies are known having several interconnected sockets in a housing so that power on a contact inserted in one socket can be distributed to contacts inserted in others of the sockets. In the present invention the sockets are hyperboloid spring sockets mounted on a metal bar spaced along its length. The sockets extend along respective bores of an insulating lower body and the bar extends along the bottom of the body being covered by a cover plate. The two end sockets are larger than the others and receive input power contacts so that power is distributed from these sockets via the bar to contacts inserted in the other sockets. Catches with inturned teeth retain the contacts after insertion. The catches are located in bores in an upper closure bonded to the lower body and are trapped between the lower body and a step in the upper closure. The catches are electrically isolated from the sockets until after insertion of a contact.

Abstract: An apparatus and method for collecting liquid spillage at rail facilities including the plurality of center pans (10) and side pans (14) arranged in end to end relation.    The pans (10, 14) are formed of a plastic material, preferably high density polyethylene. Each pan (10, 14) has a vertical drain pipe (54, 78) which fits within an elastomeric sleeve (60) about an upper drain opening (34) in a transverse drain conduit (28) positioned between a pair of crossties beneath the pans (10, 14).  Each center pan (10) has a resilient upwardly inclined side flange or lip (44). For installation, the center pan (10) is preferably installed by first inserting one resilient side flange (44) beneath the head (16) of an adjacent rail (12) and then lowering the bottom (40) of the pan (10) onto the upper surface of the crossties (24) with drain pipe (54) received in sealing relation within the aligned elastomeric seal (60).

Title: Method and apparatus for generating acoustic pulses on the surface and conveying these pulses through the drill string to the drill bit to increase rate of drilling
Inventor: WALTER BRUNO H
IPC: E21B7/24
Filed: 2001-01-09
Abstract: A method and apparatus are disclosed for generating intense acoustic pulses by means of water hammer effect on the surface and conveying these pulses through the drill pipe and drill collars down to the drill bit. Intensity of the acoustic pulses is increased in the bit nozzles. Vigorous pulsing of the fluid exiting the bit nozzles results in better cleaning of the hole bottom and faster drilling. By adding a down hole telescopic tool with multiple pistons arranged in series acoustic pulses are converted into a strong mechanical vibration which increases the efficiency of the drill bit and the whole drilling process. Vibration of the drill string reduces the friction between the drill string and the hole resulting in lower torque requirements. By adding a multiple piston telescopic tool above the drill bit and one or few drill collars acoustic pulse is converted into a strong mechanical upward pulse which causes the bottom end of the drill string to vibrate. Rate of drilling is increased while torque required for the drilling process is reduced.

IPC: A23L27/60
Filed: 1999-10-01
Abstract: Cette invention se rapporte à un concentré d'oeuf ayant un pourcentage élevé de matière solide par rapport à l'oeuf entier. Pour obtenir ce concentré d'oeuf, on mélange un composant jaune d'oeuf liquide avec un composant albumen déshydraté. On peut ensuite reconstituer le concentré en le mélangeant avec de l'eau et l'oeuf ainsi reconstitué peut être utilisé en tant que tel comme produit alimentaire, ou alors mélangé avec d'autres ingrédients, pour former des produits de boulangerie, de la mayonnaise, etc. Dans un mode de réalisation préféré, ce concentré d'oeuf est combiné avec un ou plusieurs ingrédients (par exemple du sucre et/ou du sel) pour abaisser son activité dans l'eau et pour rendre le concentré stable à la conservation, pour des périodes relativement longues (par exemple deux mois ou beaucoup plus). Dans un autre mode de réalisation, on utilise une autre procédure dans laquelle on obtient un résultat similaire par dispersion de la poudre d'albumen dans le composant jaune d'oeuf.
