Abstract: In a working machine including a belt-type continuously variable transmission, a working rotational speed of a working unit can be optionally adjusted, and stable work by the working unit is performed. A working machine 10 having a belt-type continuously variable transmission 63 in a working power transmission system 31, includes a target working speed setting section 147 for optionally setting a target working rotational speed Bs of a working unit 14, a working unit speed sensor 76 that detects an actual working rotational speed Br of the working unit, a speed reduction ratio regulation mechanism 90 that regulates a minimum speed reduction ratio of a rotational speed of a driven pulley 74 with respect to a drive pulley 72, and a control unit 43. The control unit controls a rotational speed Er of the drive source so as to bring the actual working rotational speed close to the target working rotational speed, obtains a minimum limit speed reduction ratio Ram on the basis of a target minimum rotational speed Em of a drive source 13 which is set in advance or set by the drive minimum speed setting section 142, and the target working rotational speed, and controls the speed reduction ratio regulation mechanism to keep the minimum limit speed reduction ratio.

Abstract: Embodiments of the present disclosure are directed to the technical features relating to the ability of being able to create complex robotic humanoid movements, actions, and interactions with tools and the instrumented environment by automatically building movements for the humanoid; actions and behaviors of the humanoid based on a set of computer- encoded robotic movement and action primitives. The primitives are defined by motions/actions of articulated degrees of freedom that range in complexity from simple to complex, and which can be combined in any form in serial/parallel fashion. These motion-primitives are termed to be minimanipulations and each has a clear time-indexed command input-structure and output behavior/performance profile that is intended to achieve a certain function. Minimanipulations comprise a new way of creating a general programmable-by-example platform for humanoid robots. One or more minimanipulation electronic libraries provide a large suite of higher-level sensing-and-execution sequences that are common building blocks for complex tasks, such as cooking, taking care of the infirm, or other tasks performed by the next generation of humanoid robots.
Patent CA-2960159-A1 (CA)
Title: High molecular weight, monoesterified polyimide polymer containing a small amount of bulky diamine
Inventor: MILLER STEPHEN JOSEPH
IPC: B01D71/64
Filed: 2015-12-23
Abstract: One method as described herein relates to making a high molecular weight, monoesterified polyimide polymer using a small amount of bulky diamine. These high molecular weight, monoesterified polyimide polymers are useful in forming crosslinked polymer membranes with high permeance that are useful for the separation of fluid mixtures. Another method as described herein relates to making the crosslinked membranes from the high molecular weight, monoesterified polyimide polymer containing a small amount of bulky diamine. The small amount of bulky diamine allows for formation of both the high molecular weight polyimide polymer and for covalent ester crosslinks via reaction of the carboxylic acid groups with a diol crosslinking agent. This small amount of bulky diamines reduces chain mobility or segmental motion during crosslinking and reduces large loss of permeance. As such, this method provides a crosslinked membrane with good permeance and selectivity.

Inventor: SPINELLA DONALD J
IPC: B23K11/14
Filed: 2015-12-14
Abstract: An apparatus and method for fastening layers of non-ferrous alloys, like aluminum, magnesium and copper utilizes a steel fastener and a spot welding machine.  The fastener and metals are stacked and the heat from the welder's electric current softens the lower melting point aluminum allowing the fastener to penetrate the aluminum. A  weld zone between the fastener and the various layers creates an internal weld. The fastener has a rough shaft that is coated by the molten weld zone and is hard to withdraw on solidification. Layers of non-conductive materials like plastics and ceramics may also be affixed to a conductive layer using a fastener made from a compatible material that extends through a pilot hole and welds to or penetrates a conductive layer. The fastener may have projections that initially reduce contact area with the stack.
