Title: Mixer and mixing method
Inventor: SUDO USHIO
IPC: B28C5/16
Filed: 2015-08-26
Granted: 2022-09-27
Abstract: The present invention makes it possible for gypsum slurry to be uniformly and sufficiently kneaded in a kneading area of a scraper type mixer. This mixer has a circular housing (20) forming a kneading area (10a) in which gypsum slurry is to be kneaded, a rotating disc (32) arranged inside the housing and rotating in a prescribed rotating direction, a rotating drive shaft (30) integrally connected to the rotating disc, a plurality of scrapers (50) arranged in the kneading area, and a slurry discharging port (40) disposed in a circular ring wall (23) of the housing to supply the gypsum slurry in the kneading area onto a base paper (1) for a gypsum board. The opening of the slurry discharging port is divided into a plurality of narrow openings (48, 48'), thereby increasing the flow resistance of the gypsum slurry flowing out from the kneading area. An annular base (70) which rotates integrally with the rotating disc is arranged concentrically with the center of rotation (10b) of the rotating disc, in the kneading area, and inner ends of the scrapers are fixed to the annular base. The scrapers are bent or curved backward in the rotating direction of the rotating disc.

Patent CA-3019968-C (CA)
Inventor: KOWALCHUK TREVOR
IPC: A01C5/06
Filed: 2013-09-20
Granted: 2020-06-30
Abstract: A method and system for controlling operation of a tractor and/or agricultural implement towed by the tractor is disclosed. A vibration sensor is mounted to the agricultural implement to detect the magnitude of vibration, or bounce, on the agricultural implement. Because the magnitude of the vibration is a function of several operating parameters including, but not limited to, the speed at which the tractor is travelling and the downward pressure applied to the agricultural implement, one or more additional sensors are provided to monitor these operating parameters. Each of the sensors generates a feedback signal and transmits it to the controller. The controller is configured to generate an reference signal to control an actuator as a function of the magnitude of vibration and the measured operating parameter. The actuator receiving the reference signal is configured to control operation of the tractor or agricultural implement to reduce the magnitude of vibration.

Title: Fastener-driving tool having a superconductor power source
Inventor: FAN CHINBAY Q
IPC: B25C1/06
Filed: 2017-11-03
Granted: 2021-06-15
Abstract: ABSTRACT . = Pneumatic fastener-driving tools widely used rely on costly compressed air source. Unlike pneumatic, combustion or electric fastener-driving tools, use of the fastener-driving tool of the present disclosure leads to lower costs and easier use, does not require replaceable fuel cells, and does not need a large and heavy electric motor to generate sufficient fastener-driving power.  Instead, the fastener-driving tool of the present disclosure uses relatively lightweight first and second conductive rails electrically connected to a partially conductive piston defining through holes coated with conductive material, slidably mounted on the first and second rails. A capacitor is electrically connected to the first rail so electrical current discharged from the capacitor can travel from the capacitor, through the first rail, through the piston, and through the second rail inducing a Lorentz force that acts on the piston to move the piston toward a nosepiece to drive a fastener.

Abstract: Organizations are constantly looking for faster and less expensive computer systems to manage businesses; however, the current standard in virtualization techniques includes using virtual machines, which require a long period of time to be instantiated before handling requests and are resource intensive. Using Domain Name System (DNS) queries to a DNS server as an indicator to initiate a virtual resource, such as containers, enables the system to instantiate the container prior to an end user transmitting their first request for a resource stored in that container. Containers can be initialized upon indication of a request, terminated at the end of the request process and initialized again for a next request as they can be activated at very fast speeds as needed. Additionally, using DNS queries as indicators to warm a cache of a network component enables the system components to be imminently used, to be pre-loaded with requested resources.
