Abstract: The device is composed of two, horizontally aligned component parts, namely, fixed spinway subtending an angle of 60° and a pivotal wedged-shaped module residing at a specific and constant distance parallel to the spillway face. The wedge-module is designed so that it rotates around a defined arc radius so maintaining both a constant distance between interfaces of the wedged-module and spillway and a constant angle of attack. This device has been demonstrated to accelerate the rate of fluid flow under either low or high head pressures by way of generating a negative pressure (venturi) effect in the device. The nature of the wedge-module is to present a “throat” configuration at the slit opening thereby tending to suck fluid into the device under such negative (venturi) pressures, while maintaining a laminar flow pattern ahead of the wedge-module/spillway arrangement.

Abstract: A selective optical actuation system for a plurality of electrical devices (20) comprises a variable pulse frequency pulsed light source (10) and an optical fibre network (12, 13, 14) distributing the light pulses to actuation gateway for each device, comprising a photovoltaic converter (16) whose correspondingly pulsed electrical output is applied to a ferroelectric transformer (18). Only if the pulse frequency is within the resonant band for a given transformer will the voltage be raised above a threshold value required to actuate that device. Choice of light pulse frequency thereby determines the device(s) to be actuated.

Abstract: A mattress caddy including a support strap, with handles formed at each end, and two transverse rigid cradle assemblies. To utilize the present invention in the transportation of a mattress, it is first laid out lengthwise, with the cradle assemblies positioned open-end-up, to facilitate the loading of the mattress. The cradle assemblies are then positioned along the strap at an interval that measures somewhat less than the length of the mattress with each assembly an equivalent distance from one of the handles. A long edge of the mattress is then placed into, and thereafter supported/cradled by, each of the cradle assemblies. At this point, each individual grasps one of the handles with one hand, places his/her other hand on opposite surfaces of the vertically-oriented mattress to balance the load, and lifts the mattress off of the ground/floor.

Abstract: A lawn irrigation sprinkler head that internally incorporates an alert and retrieval device which indicates the position of the head if damaged, and facilitates in-situ repair of the damaged head. The sprinkler head has a hollow body containing a pop-up riser connected to a nozzle. The alert and retrieval device is positioned between the base of the riser and the nozzle. Should the nozzle become damaged or dislodged, the alert device telescopically extends from the riser and signals the location of the damaged sprinkler head. The device facilitates the repair of the head by lifting the riser from within the sprinkler head so that a replacement nozzle can be attached. In an alternative embodiment the alert device has an integral shut-off valve which prevents the discharge of water in the event that a subsequent irrigation cycle occurs before the damaged head is repaired.

Abstract: A system for reading training for improving a subject's reading speed and comprehension. The reader reads aloud into a microphone attached to an amplifier and headset. The amplifier filters out the low frequency sounds and emphasizes the high and mid-range frequency sounds as the sounds are directed to the reader's dominant ear, which allows the reader to listen attentively with his or her dominant ear, clarifying perception and speeding the listening process. The reader is taught reading protocol, such as emphasizing, pronunciation, articulation, breathing, pausing. The reader intermittently looks into a mirror placed strategically so that he or she can observe posture and lip movement and make adjustments to these reading protocol components. The reader repeats the reading aloud and feedback until reading speed and comprehension are improved to the desired level. The reading improvement training system (inclusive of training tools and method of using the tools) improves reading skills, e.g.

Abstract: An adjustable trailer hitch which provides an operator improved remote control of the lateral position of a trailer hitch, and simplifies the procedure of hooking a trailer to a tow vehicle. The trailer hitch comprises a hitch assembly (such as a ball receptacle) attached to a roller carriage which moves from side-to-side along a bumper-like housing. The roller carriage engages a positioning screw, and an electric motor mounted in a sealed end cap powers the positioning screw. Rotation of the screw translates into rightward or leftward lateral movement of the roller carriage and consequently of the ball receptacle assembly. Motion of the ball receptacle assembly is controlled via a wireless remote control unit. Such direct control over the precise lateral position of the trailer hitch enables the operator to accurately steer the trailer when traveling in reverse.
