Patent CA-2232560-C (CA)
Title: Cles ameliorees pour serrures a barillet
Inventor: FIELD PETER H
IPC: E05B19/06
Filed: 1996-09-18
Granted: 2008-01-22
Abstract: L'invention concerne une clé avec une portion de panneton ayant une résistance mécanique transversale améliorée en dépit de découpes profondes (101) qui s'étendent profondément dans l'épaisseur du panneton. Les découpes (101) traversent au moins une des surfaces du panneton de manière à s'étendre en arc dans l'épaisseur du panneton et jusqu'à un des bords (112). Le volume du matériau de l'ébauche de la clé jouxtant les découpes profondes après que la clé a été coupée est sensiblement plus élevé que dans les clés usuelles et donne à la clé davantage de résistance pour éviter qu'elle ne casse. Les découpes (101) sont faites dans le panneton de la clé par une roue coupante rotative (120) qui est dimensionnée pour faire des découpes à surface courbe, plutôt que plate. La serrure comprend un barillet (141) ayant un tenon (142) avec une pluralité de portions en coin (144-147) et une fente (143) pour la clé traverse le barillet. Le tenon est formé pour permettre à tous les coins du tenon de rester intacts, ce qui assure un appui solide de la came de fond sur le tenon.

The spacer has a lower end supported by a support member and an upper end positioned in the large-diameter portion. A hollow cylindrical elastic member is interposed between the bolt head and the stepped portion for biasing the lower member toward the support member.

Granted: 2004-11-09
Abstract: An apparatus and method for enlargement of soft tissue, such as breast, including a vessel or dome configured to fit over the tissue which is to be enhanced or enlarged. The dome or vessel has a sealing cushion of elastic material which surrounds and encompasses the perimeter of the base of the vessel. The cushion includes a fluid compartment which is compressible. The fluid compartment is deformable such that when the vacuum is applied to the sphere, the seal material and compartment deform, isolate, and diffuse the pressure on the skin. The apparatus also includes a vacuum pump with a power source, a pressure sensor to regulate the pressure, or vacuum provided by the pump. The dome also includes a valve mechanism for controlling the ingress and egress of the vacuum to the interior of the dome. This valve will automatically close so that the pump may be removed from the dome and the pressure or vacuum therein be maintained. This valve also includes a release mechanism to remove or exhaust the vacuum in case of discomfort or emergency. The domes may also have different configurations, including rectangular, though normally they will remain as a sphere to maximize and equalize the augmentation of the flesh or tissue within the confines of the dome. The dome also is formed with a footed rim which is embedded in a deformable elastic cushion with a fluid pocket to augment the deformation and consequent reduction in the per square inch pressure applied to the tissue of the wearer.

Abstract: A method for optimising a mineral recovery process. A slurry 10 is fed to a conditioning step 20. The condition slurry 30 is then provided to a flotation circuit 40 to recover a concentrate 50. The remainder of the of slurry is then rejected as tail 60 or passed for further processing.   The present invention provide a means for analysing a sample stream 100 of the slurry. A sample stream 100 is provided to an analysis device 200 which treats the sample with an oxidising gas similar to the oxidative treatment 20. Several parameters are measured before and/or after the oxidative treatment of the slurry. The flotability characteristic of the slurry is then determined as a function of the measured parameter(s). The result may then be used to optimise mineral recovery.    This analysis equipment can be used intermittently or continuously to thereby provide on-going optimisation of the mineral recovery circuit.
