  • Publication number: 20240016105
    Abstract: A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.

  • Publication number: 20240010410
    Abstract: A container having an inverted active cage generally includes an enclosed base portion, a body portion extending upwardly from the base portion, and a top portion with a finish extending upwardly from the body portion. The body portion further includes a central longitudinal axis, a periphery, a plurality of rigidified and non-active surfaces, and a network of pillars or channels. Unlike the prior art, each of the plurality of non-active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars or channels is inwardly displaced with respect to the longitudinal axis. The plurality of rigidified or non-active surfaces, together with the network of rigidified channels or pillars, are spaced about the periphery of the container in order to accommodate vacuum-induced volumetric shrinkage of the container resulting from a hot-filling, capping and cooling thereof.

  • Publication number: 20230399940
    Abstract: A method for determining properties of hydraulic fractures from measurements of pressure in a well made after stopping pumping fracturing fluid into the well (shut in) includes determining a first time after shut in whereinafter a decrease in measured pressure is caused by fluid leak off in a fracture. A second time after shut in is determined whereinafter the decrease in pressure is caused by fluid leak off, fracture growth and fluid pressure equilibration in the fracture. A third time after shut in is determined whereinafter the decrease in pressure is caused by fluid leak off, fracture growth, fluid pressure equilibration in the fracture and pressure drop in a near wellbore zone. Values of fluid efficiency, minimum stress and net pressure which are determined result in a calculated pressure with respect to time matching the pressure measurements within a predetermined threshold.

  • Patent number: 11759552
    Abstract: There is disclosed a method of improving the reliability of coating an implantable medical device, such as a stent, with bioactive material in the absence of a carrier material such as a matrix or polymer layer. The method involves cleaning volatile components from the exposed surfaces of the medical device, removing carbon deposits and then applying a uniform carbon layer in a controlled environment. The deliberately applied carbon layer masks impurities of the underlying native oxide layer and leads to more uniform bioactive material coating not only a over the surfaces of a single medical device but also from device to device within a batch and between batches of devices. This improves production as well as optimising the amount and release of drug on the medical device without the need for a carrier material.

  • Patent number: 11752019
    Abstract: A medical device such as a stent or medical balloon is functionalised prior to coating with a bioactive material, specifically by carboxylic acidification of the contact surface or surfaces of the medical device. The preferred process involves washing a stent or other medical device in a washing solution which may be sodium hydroxide, soaking in a carboxylic acid solution, rinsing in water to remove excess carboxylic acid, allowing to dry before applying a bioactive agent layer. It has been found that washing after functionalisation removes excess carboxylic acid and enhances the retention of bioactive agent on the contact surface or surfaces of the medical device leading to a more uniform and consistent layer of bioactive agent.

  • Publication number: 20220395664
    Abstract: Devices, systems, and/or methods for immobilizing a patient's head and simultaneously providing emergency respiration for the patient includes, in some embodiments, a head immobilizer, a bag valve mask (BVM), an endotracheal tube (ET) bracket, and/or an oxygen face mask. In some embodiments where head immobilization is not needed, a cardiopulmonary resuscitation (CPR) board may be used in lieu of the head immobilizer. Each such embodiment is configured to require reduced manual intervention by a caregiver without reducing the effectiveness of each medical device and/or system. An adjustable BVM holder integrated into the head immobilizer secures the BVM on the patient. In embodiments with a BVM, only a single hand is necessary to provide emergency respiration, freeing the caregiver's other hand for other caregiving tasks. Such a head immobilizer may secure an ET bracket and/or face mask to a patient, allowing for hands-free operation during patient treatment, movement, and transportation.
