Abstract: An apparatus for feeding fish includes a member operable to be disposed in a body of water. The member has a wall for containing fish food and for defining a feeding area and the wall has upper and lower portions. The upper portion is operable to project above the surface of the water to generally protect the feeding area from wind to prevent feed in the feeding area from being blown by wind, yet provides access to the feeding area. The lower portion is operable to project sufficiently below the surface of the water to prevent the occurrence of opening between the wall and the surface of the after due to surface disturbances thereon, however, the lower portion does not project far enough below the surface to generally inhibit fish access to the feeding area.

Abstract: The invention permits outwards engagement of a magnetic tape from a conventional audio cassette for processing the tape in a manner to reduce prior art tape-to-head alignment problems. When the cassette is inserted into the apparatus, concurrently a tape engager is inserted into a lateral access opening associated with a cassette well (i.e. a capstan opening or cavity) and is positioned adjacent an inside face of the tape. The tape engager contacts a length of tape, and a head block assembly member is inserted into the well to cooperate with the tape and the tape engager to ensure separation between an outside face of the tape and the cassette, and to reduce contact between an inside face of the tape and a portion of the cassette. In one embodiment, the tape engager is rotatable to displace the tape outwardly with respect to the well.

Abstract: A lock apparatus including a shackle having first and second joined leg portions and a cross member pivotally connected to the first leg portion for pivotal rotation relative to the shackle, about a pivotal axis. The cross member has an opening for receiving a portion of the second leg portion therein when the lock is in a closed position and a bolt connected to the cross member is operable to selectively releasably engage the second leg portion when the lock is in the closed position. The apparatus further includes a lock position holder including a contact member on the cross member and a detent member on the shackle. The contact member and detent member are engageable with each other such that relative movement between the contact member and the detent member is resisted, to interfere with movement of the cross member relative to the shackle to keep the cross member and the shackle in a position of relative angular orientation.

Abstract: A marine helm pump assembly comprises a helm pump unit and a helm pump mounting cooperating with the helm pump unit. The helm pump unit is connectable with hydraulic conduits to a steering assembly and cooperates with a rotatable helm to be gripped by an operator. The helm pump mounting is securable to a portion of the marine vessel, which can sometimes be restricted to access by an operator. The helm pump unit is mounted for limited rotation with respect to the helm pump mounting about a tilt axis passing transversely through the unit and the mounting to permit the rotatable helm to be tilted or swivelled about the tilt axis through an arc centred on the tilt axis to change orientation of the helm. This tilting can accommodate orientation preferences of the operator, as well as facilitating access to, or exit from, a restricted area adjacent to the helm. Because the helm pump can rotate with respect to the helm pump mounting, problems associated with prior art articulated steering columns are eliminated.

Abstract: The grapple comprises left and right frame members hinged together at a main hinge, and left and right arms hinged together at the main hinge and having outer portions cooperating with a supporting cable. The grapple has left and right fingers to grasp a load, each finger being hinged to a respective frame member and connected to a respective arm. The grapple also includes a latching mechanism which cooperates with the fingers and arms to partially control angular relationship between the finger and the respective arm for actuation of the grapple. The latching mechanism is remotely controllable by an operator to release the load, and then requires re-setting to enable the grapple to grasp a subsequent load. The grapple is supported by a single cable extending from the arms to a helicopter and, prior to grasping a load, is positioned on the ground to straddle the load.

Abstract: A method of recovering hydrogen peroxide from colored aqueous solutions is disclosed. The solution is brought in contact with a non-ionic size-exclusion chromatography resin made up of packed particles having narrow, low molecular weight pores. The higher molecular weight colored constituents are largely excluded from the pores causing these constituents to be more rapidly eluted with water along the exterior of the particles. Hydrogen peroxide molecules are small enough to enter the pores several times in their passage through the resin which slows their progress sufficiently to cause elution of hydrogen peroxide after the colored constituents have been eluted, effectively resolving the two components.

Abstract: The invention provides a process and apparatus for on-site purification of photofinishing effluent produced by mini-lab photofinishing apparatus and the like. The process includes passing the effluent through an adsorbent to adsorb inorganic and organic compounds to produce a primary filtrate fluid. The primary filtrate fluid is directed to a membrane filter which in turn discharges relatively clean permeate fluid which passes through the membrane filter as a secondary filtrate fluid, and rejects concentrate fluid that does not pass through the membrane filter. Preferably the effluent is passed through a plurality of adsorbents of which at least one adsorbent adsorbs inorganic compounds, and at least one other adsorbent adsorbs organic compounds. The adsorbent is provided in containers, each of which has an inlet and outlet provided with conduit coupling means, and conduits interconnect the containers in a series flow path relationship.

Abstract: The invention provides an apparatus for crushing material such as rock and includes a support structure having an inlet and an outlet. A powered rotor shaft rotates with respect to the support structure about a shaft axis, and a rotor mounted eccentrically on shaft describes orbital motion about the shaft axis. The rotor has a rotor wall which moves cyclically and laterally with respect to the axis during the orbital motion. At least one stator is mounted in the support structure to provide a stator wall spaced oppositely from the rotor wall to define therewith opposing walls of a crushing chamber located between the inlet and outlet. Feed direction of material passing between the inlet and outlet is generally perpendicular to the shaft axis, and when the rotor describes the orbital motion, spacing between opposing walls of the chamber varies cyclically. The stator is mounted yieldably so as to move away from the rotor when a pre-determined threshold force is exceeded so as to reduce possible damage.
