Abstract: A vented shoe having a conventional upper. An outer sole of flexible compressible material engages the periphery of the upper. A series of fluid passages extend through the outer sole from concavities formed in the outer surface of the outer sole. These fluid passages are continuous with larger openings formed in a filler overlying the inner surface of the outer sole, and with holes formed in the inner sole. The concavities are preferably formed and defined by annular grooves extending inwardly from the outer surface of the outer sole in a regular repeat pattern. Preferably ribs are formed on the outer surface of the outer sole coaxial with the concavities.

Abstract: An automatic grinding machine is disclosed for finishing the edges of rectangular articles such as the glass plates used in welder's helmets. The machine includes an inclined channel to receive a supply of plates provided with an escapement mechanism at its lower end which operates to release a single glass plate during each machine cycle. The plates are pushed by a linear actuator along first track. Grinding wheels located along the first track grind opposed edges of the plates as they move along such track. A second track intersects the first track at right angles and a second linear actuator pushes single glass plates into the second track after they are delivered to the entrance end of the second track from the first track. As the plates move along the second track the other opposed edges are finished by a pair of grinding wheels.

Abstract: The electric potential output from a battery and generator assembly is monitored by three electric indicator circuits, one of which includes a first indicator which is activated to indicate excessively low battery voltage when the normally deactivated transistor switch in said circuit is activated by deactivation of a bias control transistor resulting from deactivation of a zener diode when the output voltage from the assembly drops below a predetermined minimum; a second indicator circuit of which includes a second indicator which is activated to indicate excessively low generator charging voltage when the normally activated transistor switch in parallel with said second indicator is deactivated by deactivation of a zener diode when the output voltage from the generator drops below a predetermined minimum; and a third alarm circuit of which includes a third indicator which is activated to indicate excessively high generator charging voltage when the normally deactivated transistor switch in said third circui

Abstract: A curved wall panel made of fiberglass-polyester resin composite and having a main wall section, in which steel straps (or other high modulars or high stiffner material straps) are circumferentially embedded, and an inwardly recurved section at each side thereof which terminates in a radially disposed and outwardly extending flange. The side-by-side flanges of adjacent panels are conjoined to form a joint which is outwardly spaced from the pair of flanges. The plastic portions of the bolted butt joint formed thereby are in compression only from the bolts and from the hydrostatic pressure while the steel bolts and straps are in tension only. A plurality of conjoined ring panels form a ring module. Outwardly disposed ring panels at the top and bottom of each wall panel enable a ring module to be placed on the rim section of a base formed of pie-shaped elements and to be stacked to form a field-erected tank having horizontally disposed and movement-permitting ring joints above and beneath each ring module.

Abstract: A throat formed between jaws of a rigid bifurcate gripper can be moved horizontally to receive an edge portion of sheet structure. The gripper is freely tiltable so that application of a lifting force to it will effect tilting of the gripper relative to the sheet structure to bind such structure between the jaws. Normally the gripper is positioned by a counterweight with its elongated throat horizontal. The lower jaw is of reflex angle shape and is positioned relative to the upper jaw so that downward tilting of the jaws will cause them to bind the sheet structure in the gripper throat.

Abstract: A ship's steering unit comprising a housing, a cable wheel mounted within the housing, a shaft with a pinion thereon in driving engagement with the cable wheel, and a one-piece body which serves as a bearing support for the shaft, the shaft having a shroud portion providing a member for mounting the unit to a support surface, which when the unit is orientated with its housing lowermost is spaced below the upper region of the shaft and the bearing support therefor.

Abstract: A mechanism for opening and closing an angularly movable panel, comprising a drive box for attachment to a fixed frame, the drive box housing a cable wheel rotatable upon translation of a control cable when in operative association therewith, a chaincase having a sprocket operatively connected with a chain located in a casing, the chain being for attachment at one end to an angularly movable panel, rotation of the sprocket effecting translation of the chain into, or out of, the casing in accordance with the sense of sprocket rotation, the chaincase being mountable in any of four different positions on the drive box.

Abstract: An operator mechanism for translating the core of a cable having a casing guiding the core, comprising a cable wheel mounted for rotation inside a housing, the cable wheel being adapted for attachment of the core to a defined region of the periphery thereof so that the core, when so attached, will, at its attached area, be rotatably fast with the peripheral region of the cable wheel, a handle for rotating the cable wheel, the handle being positioned outside the housing and adjacent a forward end face thereof, the handle being capable of operative securement with respect to the cable wheel in any of a plurality of angular orientations relative thereto about the axis thereof.

Abstract: A system is disclosed for removing squeal or noise from automotive disc brake assemblies. An emulsion of a normally soft polymer together with a cellulosic thickener, an anti-freeze compound, biocide and pigment is coated onto the back side of the outboard pad assembly. When dry the outboard pad assembly is mounted on an automotive disc brake assembly.

Abstract: A seat arm adjustment mechanism has a stop block attached to the back of a seat, and a shaft slidably mounted in a housing on the arm bears against the stop block. A locking arm is slidably mounted on the shaft within a slot in the housing. A spring, disposed in the housing and positionally held by a screw, effects a biasing force against a face of the locking arm. A raised portion of the locking arm bears against a face of the housing. A second spring mounted on a screw between an end of the shaft and a bracket moves the shaft toward the stop block. An elongated rod is slidably mounted on the arm to bear against a face on the locking arm opposite the first spring. Pushing the rod against locking arm allows the locking arm to slide along the shaft, while the arm is being moved to a new selected position. The arm may be raised and lowered, whereupon it stops at the last selected position.

Abstract: Transponder apparatus and a corresponding method for use in a security polling system having a central controller and a number of remotely located transponders which are polled sequentially to initiate transmission of status conditions, over telephone lines to the central controller for monitoring. The transponder detects polling signal bursts of a particular frequency from the central controller, and counts the bursts to determine its turn for response. Each response includes two sequential signal bursts of different frequencies, the durations of which define, with the frequency sequence, the status condition being transmitted. Control information is encoded into the lengths and spacings of the polling signal bursts, and is decoded by the transponder, to indicate transmission errors, transponder resetting commands, and remote control commands.

Abstract: A liquid aquifer energy storage method by which hot water is collected and stored in underground aquifers during the summer months and made available for heating during winter months. The liquid aquifer energy storage method also allows for the storage of cold water during the winter months for use in cooling during the summer months. The liquid aquifer energy storage method includes heating water and hot and warm zones within the aquifer or aquifers for storage of hot and warm water, respectively. Additionally, the method includes cooling water and cold and cool zones in the aquifer or aquifers for storage of cold and cool water.
