Abstract: A socket retaining tool for preventing separation of a socket from a drive shaft of a driving tool. A keeper sleeve is configured to accommodate insertion and reciprocal movement of a quick change adapter and a quick change sleeve under the action of a biasing member. The quick change adapter has a male end and an opposite female end. The male and female ends are constructed and arranged to be used with locking mechanisms such that the socket is connected to the male end, and the drive shaft is connected to the female end. A socket locking mechanism coupled to the male end is enclosed by the keeper sleeve, and a driver locking mechanism coupled to the female end is enclosed by the quick change sleeve, when the socket retaining tool is in a relaxed position, thereby avoiding unwanted release of the locking mechanisms.

Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

Abstract: A method for fabricating three-dimensional structures. In-flight heating, evaporation, or UV illumination modifies the properties of aerosol droplets as they are jetted onto a target surface. The UV light at least partially cures photopolymer droplets, or alternatively causes droplets of solvent-based nanoparticle dispersions to rapidly dry in flight, and the resulting increased viscosity of the aerosol droplets facilitates the formation of free standing three-dimensional structures. This 3D fabrication can be performed using a wide variety of photopolymer, nanoparticle dispersion, and composite materials. The resulting 3D shapes can be free standing, fabricated without supports, and can attain arbitrary shapes by manipulating the print nozzle relative to the target substrate. Multiple materials may be mixed and deposited to form structures with compositionally graded material profiles, for example Bragg gratings in a light pipe or optical fiber, optical interconnects, and flat lenses.

Abstract: An electrical cable connector includes a contact subassembly and a housing. The contact subassembly is terminated to an electrical cable. The contact subassembly includes a center contact, a dielectric holder, and an outer contact. The contact subassembly has a protrusion extending outward from an outer surface of the contact subassembly. The housing defines a cavity that receives the contact subassembly therein. The electrical cable extends from the housing through an opening at a rear end of the housing. The housing includes a retention mechanism that engages the protrusion of the contact subassembly to secure an axial position of the contact subassembly in the cavity relative to the housing. The retention mechanism allows the housing to rotate relative to the contact subassembly and the cable.

Abstract: An acceleration measuring device is disclosed, for use as a gravimeter or gradiometer for example. The device has a support and a proof mass, connected to each other by at flexures allowing displacement of the proof mass relative to the support. The support defines a space for displacement of the proof mass. The device is configured so that the modulus of the gradient of the force-displacement curve of the proof mass decreases with increasing displacement, for at least part of the force-displacement curve. This is the so-called anti-spring effect. The resonant frequency of oscillation of the proof mass is determined at least in part by the orientation of the device relative to the direction of the force due to gravity. The proof mass is capable of oscillating with a resonant frequency of 10 Hz or less. The proof mass has a mass of less than 1 gram.
