Patent number: 11325811Abstract: The disclosure relates to a mine shaft conveyance safety brake for controlling the rate of deceleration of a free-falling conveyance, operating within or upon fixed shaft guides, in a vertical, substantially vertical or inclined mine shaft. The safety brake includes an activation system, one or more guide clamp assemblies operable for locking onto one or more shaft guides, one or more braking assemblies and one or more brake paths attached upon the conveyance. Upon detection of a conveyance suspension failure or slack rope condition associated with a free-falling or obstructed condition of the conveyance, the activation system is triggered, causing each guide clamp assembly to self-lock onto a shaft guide. Upon further downward travel of the conveyance, the braking assemblies travel upwardly upon the brake paths, generating increasing braking forces in a controlled manner until the conveyance comes to a controlled stop.Type: GrantFiled: April 4, 2018Date of Patent: May 10, 2022Inventors: Donald Todd Kennedy, Henry T. Laarakker, Marcus Thiesen

Patent number: 10501232Abstract: An adjustable wrap-around container system is provided comprising a plurality of connectable modules. Each module includes an outer perimeter wall and an inner perimeter wall defining an outer volume therebetween, the inner perimeter wall surrounding an inner volume that may contain, for example, a post. The inner and outer perimeter walls may both include two segments, joined at an angle, such as 90°, at their inner edges. A module connects to an adjacent module by sliding a tab on the module into a slot in the adjacent module. By adjusting how far each module slides into the adjacent module, the dimensions of the inner volume may be varied. The assembled container can retain solids, such as soil for plants, liquids, or other materials.Type: GrantFiled: July 11, 2017Date of Patent: December 10, 2019Inventor: Donald Todd Price

Patent number: 6621565Abstract: An optical transmitter for use in position location or position measurement systems includes (i) an assembly including two optical sources that generate two optical beams which diverge in known ways in a first and second plane, respectively, and are narrow in the orthogonal planes, (ii) a power source which provides power to the assembly to rotate it at a constant angular velocity or with a previously known pattern of velocities through each complete rotation of the assembly, and (iii) a signaling unit that emits a synchronization signal at a specific rotational position of the assembly. The optical transmitter can be used in systems for determining points, lines, planes, distances, areas, volumes, azimuth, elevation, range, angles, or any other positional or spatial variable. The optical transmitter has wide application in, for example, surveying, construction, and the creation of virtual or real environments.Type: GrantFiled: September 10, 2001Date of Patent: September 16, 2003Assignee: Arc Second Inc.Inventors: Timothy Pratt, Scott C.

Patent number: 5771900Abstract: A contraceptive diaphragm having a rim surrounding a thin membrane, the membrane having a cervical dome extending downwardly from a posterior portion of the membrane. The rim has two curvilinear bands joined together at their respective ends and encased in a coil spring. The shape of the bands creates a rim which curves slightly upwardly at the anterior end of the diaphragm and slightly downwardly at its posterior end. The rim is formed with a curvilinear profile which provides an advantageous fit. A small dome projects upwardly from an anterior portion of the membrane which is grasped by the wearer to remove the diaphragm.Type: GrantFiled: July 22, 1997Date of Patent: June 30, 1998Assignee: PathInventors: Glenn D.

Patent number: 4632114Abstract: A urethral sphincter cuff is adapted to be surgically implanted so as to encircle the urethra. When the sphincter cuff is filled, the urethra is squeezed, and the patient is continent. When the cuff is deflated pressure is released from the urethra and urine may flow therethrough.The sphincter cuff is provided with a tongue and buckle to allow adjustment during surgical implantation. The tongue, on one side of the cuff, contains apertures which are adapted to fit onto studs on the buckle part. After placement and adjustment of the cuff an adhesive can be applied to secure the tongue to the buckle.The cuff also contains an occluding diaphragm which, when filled, squeezes the urethra to inhibit fluid flow, and when unfilled remains in a second position in which no tension is applied to the urethra. Even when the diaphragm area is reduced to its minimum value (with pressure on the urethra) the diaphragm remains under tension so that its smooth surface does not wrinkle.Type: GrantFiled: March 22, 1985Date of Patent: December 30, 1986Assignees: C. R. Bard, Inc., The Johns Hopkins UniversityInventors: Donald A. Todd, Robert E. Fischell
