Title: Water conservation milkhouse sink
Inventor: FORBES RONALD
IPC: E03C1/00
Filed: 1991-07-03
Abstract: Abstract "In a sink for the washing of tie-stall dairy farm milk pipeline systems, it is known to have a rounded bottom in which the milking machines are placed prior to the washing procedure. During the washing procedure, this sink acts as a reservoir for the cleaning solution which is drawn up through the bottom of  the milking machine inflations, circulated through the pipeline system and returned to the sink. In this invention, there is a trough at the bottom of the sink which is slightly wider the width of two milking machine inflations. In this way, the bottoms of the inflations are held at the bottom of the sink and less water is required to be initially put in the sink for the bottoms of the inflations to remain submerged throughout the washing procedure. In addition, the sides of the sink slope into the trough in such a way as to rapidly reduce the volume of water in the sink as the elevation of this water decreases."

Filed: 1991-12-09
Abstract: A resonant type switching power source implementing zero voltage switching on the basis of the resonance between an inductor and a capacitor. A main switch is connected to the primary side of a main transformer.   A pulse width control circuit generates a control signal for varying the turn-on time of the main switch until the output voltage of the secondary side of the tranformer being fed back reaches a predetermined value.  A resonance capacitor is connected in parallel with the main witch. When the terminal voltage of the capacitor crosses zero potential toward the negative side, the pulse width control circuit delivers an ON command to the main switch. Alternatively, the ON control over the main switch may begin at a time a predetermined period of time later than the time for turning on the resonant circuit.

Abstract: A gate assembly includes a stationary support with upper and lower apertured brackets. A gate has a tubular upright whose open upper and lower ends are received by the brackets. End caps extend into the open upright ends and seat against the brackets to secure the gate to the support for rotation about a vertical rotational axis. Upper and lower coil springs are mounted within the upright in alignment with the rotational axis. The end caps have slots which receive and secure one end of each spring to the support. An internal shaft is fixed to the upright between the coil springs. It has vertical slots that receive and secure an opposite end of each spring to the tubular upright for rotation with the gate. The end caps can be rotated and fixed to the brackets with bolts to adjust tension in the springs and consequently the rest position of the gate relative to the support. The springs wind in a common direction to ensure bidirectional operation.

Title: Electrically actuated and controlled auxiliary hydraulic system for skid steer loader
Inventor: JACOBSON SCOTT B
IPC: E02F3/96
Filed: 1992-05-29
Abstract: The present invention relates to an electrically actuated and controlled auxiliary hydraulic system for controlling the flow of hydraulic fluid under pressure to mounted attachments on a skid steer loader.      In one embodiment, an electrically actuated auxiliary control valve is coupled to the front and rear mounted attachments through an electrically actuated diverter valve. In a second embodiment, a front and a rear auxiliary control valve is coupled to the front and rear mounted attachments. An operator can select between control of either the front or rear attachments by selectively actuating the forward, reverse and latch switches on the control handles. A mode control switch electrically coupled to an auxiliary mode control circuit allows the cyclical selection between the disable mode, the momentary made, and the latch mode.      In the disable mode, the actuation of the forward, reverse or latch switches has no effect. In the momentary mode, the operator controls the particular attachment during the time of the switch actuation. In the latch mode, the front attachment can be operated in a high pressure mode allowing extra power to be delivered to the front attachment.

Abstract: A power mine door system including a door frame to be installed in a mine passageway to define a generally rectangular doorway.  A mine door is defined by a pair of generally rectangular door leafs which are hinged on the door frame at opposite sides of the doorway for swinging between an open position to permit passage through the doorway and a closed position in which the door leafs are generally coplanar and close the doorway.  The door leafs are so dimensioned that there is a substantial vertical gap between the door leafs when they are closed to accommodate convergence of side walls of the passageway.  A relatively wide vertical sealing flap is secured to one of the door leafs for overlapping a face of the other door leaf when the door is closed for covering the gap between the door leafs.  A power mechanism for opening and closing the door leafs is operable to control the sequence in which the door leafs close so that the door leaf carrying the sealing flap closes after the other door leaf for ensuring that the sealing flap closes against the face of the other door leaf

Filed: 1992-09-23
Abstract: Apparatus for dyeing tissues sampled from a living body for the purpose of observing immunoreaction of the tissues has a dyeing tray with a plurality of plateaus arranged in parallel disposition. A slide is so placed over each plateau that a wedge-shaped gap of capillary dimension is formed between the plateau and the undersurface of the slide to which a sampled tissue is attached. A liquid drip surface and a liquid discharge port are formed at one end of the top surface of each plateau. A liquid delivery port is formed on a side wall of the tray so as to communicate with the liquid discharge port. The liquid delivery port and the drip surface are always exposed. A dyeing liquid or a rinsing liquid is dripped onto the exposed drip surface and spreads into the gap for dyeing the tissue or rinse the relevant parts. After the dyeing or rinsing, the used liquid is sucked and discharged by way of the liquid delivery port. Because of the exposure of the drip surface and the liquid delivery port, the operation is easy and the dyeing tray can also be used for manual dyeing. A bank between the liquid discharge port and the drip surface prevents direct flow of the liquid therebetween.
