Patent number: 11779783Abstract: A fall-protection apparatus with a drum and a rotationally-activated braking device including at least one velocity-actuated pawl that is mounted on a pawl-support plate that is rotatable relative to the drum through a predetermined range between a first position and a second position. The pawl-support plate is rotatable relative to the drum from the first position to the second position upon the pawl-support plate experiencing a rotational acceleration that is above a predetermined threshold value of rotational acceleration. When the pawl-support plate is in the second position, the velocity-actuated pawl can be actuated by a rotational velocity that is lower than a rotational velocity required to actuate the pawl when the pawl-support plate is in the first position.Type: GrantFiled: June 23, 2021Date of Patent: October 10, 2023Assignee: 3M Innovative Properties CompanyInventor: Greg E. Schrank

Publication number: 20200113729Abstract: Aspects of the present disclosure provide for a patient warming system having a heating device configured to transfer heat to a patient based on a body heat score that indicates whether the patient is likely to sweat. The heating device includes a heater circuit configured to produce heat, the heater circuit thermally coupled to the patient. The heating device also includes a controller communicatively coupled to the heater circuit. The controller has one or more processors configured to receive one or more physiological indicators of the patient, determine the body heat score from one or more physiological indicators, determine whether the body heat score meets a score threshold, direct the heater circuit to produce a first amount of heat based on whether the body heat score meets a score threshold.Type: ApplicationFiled: June 20, 2018Publication date: April 16, 2020Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: DANIEL P.

Patent number: 9737378Abstract: A device for dispensing a dental material has a cartridge with a dispensing end. The dispensing end has a dispensing opening for the dental material. The dispensing end further has in essence an axially symmetric shape with a truncation. The truncation provides the dispensing end with a generally flat dispensing surface through which the dispensing opening extends. The device has further a cap received on the dispensing end. The cap and the dispensing end are rotatable relative to each other between an open position, in which an orifice in the cap uncovers the dispensing surface, and a closed position, in which a closed space is formed between the cap and the dispensing surface. The device allows for a relatively convenient dispensation of dental material, in particular for a dispensation of a dental composite filling material.Type: GrantFiled: July 24, 2014Date of Patent: August 22, 2017Inventors: Bruce R. Broyles, Christopher J. Claypool, Marc Peuker, Greg E. Schrank

Publication number: 20160278881Abstract: Systems and methods of manufacturing dental restorative material packaged articles. A loaded barrel is retrieved from a plurality of identical loaded barrels, each including a universal barrel containing dental material and having a plunger coupling feature. A desired plunger assembly is selected from supplies of first and second plunger assemblies each including a plunger shaft, an auxiliary device, and a complimentary coupling feature. The first plunger assemblies differ from the second plunger assemblies. The selected plunger assembly is assembled to the loaded barrel, including engagement between the plunger coupling feature and the complimentary coupling feature. The resultant construction provides a packaged article that is operable to progressively dispense material by manipulation of the plunger assembly. Optionally, an outer sleeve and/or a cap is selected and assembled to the universal barrel.Type: ApplicationFiled: November 5, 2014Publication date: September 29, 2016Inventors: Bruce R.

Patent number: 7510462Abstract: In one embodiment, a cutting tool assembly used for creating grooves in a microreplication tool is described. The cutting tool assembly includes a mounting structure and multiple diamonds mounted in the mounting structure. For example, first and second tool shanks having first and second diamond tips can be positioned in the mounting structure such that a cutting location of a diamond cutting tip of the first tool shank is a defined distance from a cutting location of a diamond cutting tip of the second tool shank. The defined distance may correspond to an integer number of pitch spacings, and may be accurate to within a tolerance of less than approximately 10 microns.Type: GrantFiled: June 16, 2006Date of Patent: March 31, 2009Assignee: 3M Innovative Properties CompanyInventors: William J.
