Patent CA-2002779-C (CA)
Inventor: CONSTANTINIS DANIEL ALEXANDER
IPC: A62B1/06
Filed: 1989-11-10
Granted: 1996-11-19
Abstract: A device whereby personnel or other loads may descend from an elevated position at a controlled and variable speed, comprising a restraining member (12) having a series of slots (13).  A tape stored in a container (20) passes through the slots (13) to a hook (10) for attachment of the device to a fixed point.  A user wearing a harness (21) removably attached to the restraining member (12) may descend at a controlled rate determined by a light load applied to the tape (11) below the restraining member (12) owing to the frictional contact of the tape (11) passing around the edges of slots (13).  After the descent a quick release shackle (16) releases the harness (21) from the device.

Title: Dilatation catheter with fluted balloon and method for manufacture
Inventor: SMITH CHARLES E JR
IPC: A61F2/958
Filed: 1989-12-11
Granted: 2002-07-30
Abstract: A balloon dilatation catheter is provided with a fluted balloon defining at least three wings. When the balloon collapses, it tends to assume the fluted configuration which defines a lower profile better adapted to pass through narrow channels, such as in endoscopes and guide catheters. The balloon is formed from a polymeric material in a method that involves the steps of tensioning the balloon to cause it to form flutes while maintaining its interior under vacuum and subjecting the balloon, while so held, to heat and, thereafter, cooling the balloon while maintaining it in its tensioned, fluted configuration.

Title: Female hydraulic coupler with push-connect and lever disconnect
Inventor: DURANT DOUGLAS M
IPC: F16L37/23
Filed: 1990-01-19
Granted: 1994-03-29
Abstract: FEMALE HYDRAULIC COUPLER WITH PUSH-CONNECT AND LEVER DISCONNECT                   Abstract of the Disclosure A female coupler can operate in both a push-pull and a lever-actuated connect/disconnect fashion.  Double lock ball controlling ramp surfaces are provided around the receiving bore of the coupler to allow the lock balls of the coupler to withdraw from the receiving bore when the receptacle is moved either into or out of the housing.  The coupler can be moved into or out of the housing by pushing the male coupler into or pulling it out of the female coupler, or by use of a lever-actuated cam.  A piston-type flow-check valve is provided to open the male check ball and hold it open despite transient surges.  This flow-check valve is hydraulically actuated.  A bleed valve for the hydraulically actuated flow-check valve is activated to release the flow-check valve when the lever is actuated or when the receptacle is pushed into the housing, thereby reducing the force needed for coupling.  The lever can bleed and activate a plurality of couplers simultaneously, whereby multiple couplers can be connected or disconnected simultaneously.

Title: Optical fiber cable core
Inventor: PANUSKA ANDREW JOHN
IPC: G02B6/44
Filed: 1990-10-09
Granted: 1995-12-05
Abstract: An optical fiber cable core (20) which is sold to a cable manufacturer for oversheathing or for incorporation into electrical power aerial cables, for example, includes in a preferred emdobiment at least one bundle (23) of optical fibers (25-25). The at least one bundle is disposed in a tubular member (30) which is made of a plastic material suitable for use in relatively wide temperature range. The core is manufactured to cause a predetermined excess length of fiber to be disposed in the tubular member. The excess length of each fiber is such that it is sufficient to avoid undue strains on the fiber as the cable core is exposed to the elements and to forces imparted during handling such as during installation. On the other hand, the excess fiber length must not be so great as to result in undue curvature of the fiber or excessive interactive engagement of the fiber with an inner wall of the tubular member. Also, the plastic material of the tubular member must be such that it responds linearly to the application of tensile forces up to a strain corresponding to the excess fiber length at a given temperature.

Title: Methods of and apparatus for making coated optical fiber
Inventor: PETISCE JAMES RAYMOND
IPC: B01J19/12
Filed: 1991-02-20
Granted: 1996-03-26
Abstract: In the manufacture of coated optical fiber, fiber (21) is drawn from a preform (22) and coating with one or preferably two layers (42,44) of light curable coating materials. Afterwards, the coating materials are cured. Increases in manufacturing line speed may be achieved if the cure speed of the coating materials is increased. This is accomplished by the simultaneous application of a magneticfield during irradiation of the curable coating materials to enhance the crosslinking of the coating materials by a free radical polymerization mechanism.  Upon absorption of light, a photoinitiator in each composition cleaves to produce two free radical fragments in the spin paired or singlet state. The magnetic field has the effect of enhancing the production of spin parallel radicals which enhances the polymerization initiation of the coating material, thereby allowing an increase in the manufacturing line speed through drawing and coating apparatus.

The first and the second passband delay characteristics have first and second ripple amplitudes.  Preferably, the first and the second ripple amplitudes are given opposite polarities.  More preferably, the second ripple amplitude is substantiallly equal to the first ripple amplitude.          It is possible to use the first and the second surface acoustic wave rolloff filter circuits either separately in the modulator and the demodulator devices or only in the modulator or the demodulator device.

Granted: 1997-04-22
Abstract: A vehicle fuel pumping unit (10) wherein a reserve fuel supply container (27) is located within the fuel tank (12) to supply liquid fuel to a motor-operated pump (43) when the tank is nearly empty. The invention addresses the problem of pump starva-tion when the tank is nearly empty and the liquid fuel is held away from the pump intake passage due to abrupt sustained turning or other maneuvers of the vehicule. In preferred practice of the invention normal fuel flow from the tank to the pump is con-trolled by an annular float valve (40, 42) located directly below the reserve fuel supply container. Fuel flow from the reserve con-tainers is controlled by a pressure-responsive valve (54) located in the suction path between the container and the pump intake (46). The pressure-responsive valve is part of a sub-assembly including a liquid fuel filter screen (55) for filtering all fuel from the container and a valve seat (48) for the pressure-responsive valve.

Abstract: A call processing method where a transferring station can be disconnected from a call after the call is transferred to a third station, but where the call is automatically returned to the transferring station in response to eitherdisconnect signaling or other predefined signaling, e.g., a flash or a dual-tone-multi-frequency (DTMF) tone, without requiring any station to dial the transferring station. The transferring station is for a subscriber to a new, transfer-with-return feature. The feature is invoked for the call either in response to a signal from the transferring station requesting invocation of the feature or because the subscriber has only the transfer-with-return feature and no other transfer feature. The call is also returned in response to a busy or no answer condition of the third station. In an arrangement comprising a switching system connected to the transferring station, and an adjunct switch also connected to the switching system, the initial connection may be from the calling station through the switching system, the adjunct switch, and back through the switching system to the transferring station. After the transfer, the connection need not go through the adjunct switch.
