Patent CA-2023709-A1 (CA)
Title: Over-pressure relief valve
Inventor: GIMBY DAVID R
IPC: B60K15/01
Filed: 1990-08-21
Abstract: ABSTRACT OF THE DISCLOSURE      An over-pressure relief valve to be positioned within an opening of a vessel, the relief valve having a valve member with a closed end which is positioned within the opening and which carries an O-ring adjacent to the closed end.  The O-ring normally engages the vessel in a circumferential pattern surrounding the opening to seal the opening. The valve member further has a second end within the vessel and the second end is resiliently biased toward the interior of the vessel by a coil spring.  The coil spring is trapped between a radial flange of the valve member, which is positioned at the second end thereof, and the inside of the vessel.  An over-pressure condition within the vessel overcomes the effect of the coil spring and moves the valve member to break the sealing engagement between the O-ring and the vessel.  An initial, limited degree of venting occurs through an annulus which is formed between the opening and the valve member.  Further venting occurs, if needed, by way of an internal passage in the valve member which extends from the second end to an opposed pair of radial passages that are positioned entirely within the vessel when the O-ring is in sealing engagement with the vessel.

Title: System for monitoring play of a golfer
Inventor: MATTHEWS GORDON H
IPC: A63B57/00
Filed: 1991-01-09
Abstract: IMPROVED SYSTEM FOR MONITORING PLAY OF A GOLFER            ABSTRACT OF THE DISCLOSURE      A system for monitoring play of a golfer (24,  26) comprises Location Information Transmitters (LIT) (52, 54, 56) at predetermined locations within a golf course and a Mobile Electronic Transmitter/Receiver  (METAR)  (48,  50) carried in association with a golfer (24, 26) on a golf bag (30)  or  a  golf  cart  (28).    Each  LIT  (52,  54,  56) periodically  transmits  a  LIT  code  over  a  restricted transmission range (58, 60, 62) such that when the METAR (48) arrives within an LIT (54) transmission range (60), the METAR  (48)  receives the LIT code and subsequently initiates a counter to measure time required by the golfer (24) to move within transmission range (62) of a next LIT (56).  If the counter exceeds a prescribed time, then a display on the METAR (48) indicates slow play.     Additionally, the METAR (48) transmits the received LIT code and a METAR code to a Tracking Center (22) display terminal.  Golf course personnel can monitor the display terminal and determine play of golfers (24, 26), golf cart (28, 34) utilization and golf hole (10, 14) utilization. When the golfer (24)  causes a slow play indication, the Tracking Center (22) is notified and the slow golfer (24) is asked to increase the rate of play or leave the golf course.

Patent CA-2034817-A1 (CA)
Inventor: KRUEGER R ERNST
IPC: F16L57/00
Filed: 1991-01-23
Abstract: A drill pipe/casing protector is mounted on a drill pipe that rotates within a well bore or a casing cemented in a well bore in which drilling operations are conducted.    The drill  pipe/casing protector comprises a protective sleeve preferably made from a compressible material secured to the exterior of the drill pipe to rotate with the drill pipe during normal drilling operations and to contact the  casing and thereby prevent damaging contact between the drill pipe and the casing. The sleeve rotates with the drill pipe during normal drilling operations in which there is an absence of contact between the sleeve and the casing, but the sleeve stops rotating or rotates very slowly while allowing the drill pipe to continue rotating  within the sleeve, upon frictional contact between the sleeve and casing.  One or more thrust bearings rigidly affixed to the drill pipe maintain the sleeve in a fixed axial position on the drill pipe during contact between the sleeve and the casing.   The relative rotation between the sleeve and drill pipe during contact reduces torque on the   rotary drill pipe compared  with     a conventional protector rigidly affixed to and rotatable with the drill pipe. The sleeve includes spaced apart longitudinal grooves and wedged I.D. faces between the grooves for circulating drilling fluid through the space between the sleeve and rotary drill pipe for maintaining a fluid film in the space to reduce frictional drag between the rotating drill pipe and the sleeve when the sleeve stops rotating. The thrust  bearings likewise to reduce induced torque by pumping fluid through a series of ramps and slots to lubricate and support the sleeve.

IPC: B60G17/015
Filed: 1991-09-10
Abstract: A monoflow shock absorber (30) is provided with a blow off valve (104) which provides the principal flow restriction during both extension and compression of the shock absorber (30).  The force biasing the blow off valve (104) closed is controlled by a control piston (124) which is connected to the blow off valve plate (104) by a rigid, solid rod (108).  The piston (124) responds to a pressurized control fluid, the pressure of which is selected by a high speed pressure regulating device such as a servo valve (20).  This system provides high speed adjustment of the damping force of the shock absorber (30), substantially independently of the stroking speed of the shock absorber (30).  The shock absorber (30) includes a cylinder (40) in which a working piston (58) moves, and the cylinder (40) is closed at one end with an inner cylinder head assembly (44) made up of a body (46) and a cap (48), which define a manifold (56) therebetween.  An external heat exchanger (160) is coupled to the base of the shock absorber (30) to receive working hydraulic fluid which is passed through the blow off valve (104), and to return the working hydraulic fluid to the shock absorber (30) after passage through the heat exchanger (160).

One such label (26) on the cap (18) has readily tearable tab portions (28) extending therefrom and tautly secured to the container (10), to tear apart when the cap (18) is first removed. A  second label (32), secured to the container (10) and overlapping the tearable tab portions (28), includes inner and outer sheets (34, 36) separably adhered together. The outer sheet (36) can be peeled back to reveal information on the interfacing surfaces (34o, 36i) of both sheets (34, 36), and then re-adhered to the inner sheet (34). A third label (38), separably adhered to the first label (26) on the cap (18), may be peeled away and re-adhered to some other surface for reference after the product (C) has been removed. A thumb tab (24) on the cap (18), to facilitate cap (18) removal, is used also to orient the container (10) and cap (18) for appropriate placement of the labels (26, 32, 38), and to orient the resulting package (P) in a cooperating displaying and dispensing device (D). That device (D) comprises an upstanding, open-ended, transparent, tubular chute (50) having a longitudinal slot (58) extending down a rear side thereof and configured to receive the package (P) through its open top end (52), with the thumb tab (24) projecting rearwardly (d1) through the slot (58), thereby orienting the package labels (26, 32, 38) to face forwardly (d2) in a desired display direction (dd). The package (P) is gravity-fed to the open bottom end (54), where it (P) is supported (78) and oriented for convenient removal.
