Abstract: This invention is a reusable apparatus and method of using the apparatus for supporting decking and forms used in constructing a bridge, roadway or other elevated surface. The apparatus is easily attached to the load bearing beams and is readily adjustable to proper grade without the necessity of shims.

Abstract: A flanged trough is provided having flanges along each side of the trough with a smooth continuous curve between the flanges and the body of the trough and a bar of metal welded along the underside of each longitudinal edge of the metal sheet before the flanges are formed. The junction between the metal bars and the flanges and the welds can be covered with a sealant to form a sanitary seal. A lid and gasket can be placed over the trough to seal the contact area of material in the trough from the junction between the metal bars and the flanges of the trough to form a weather-tight, dust-tight and gas-tight conduit.

Abstract: This invention relates to a structure particularly adapted for use with an automatic teller machine. More particularly this invention relates to an environmentally controlled structure particularly adapted to permit installation of an automatic teller machine at a new or existing facility or other remote site.

Abstract: An articulated aerial device is provided which includes a workman's basket suspended from a movable beam. The basket is attached to the movable beam by an attaching means which selectively permits the basket to rotate for permitting easy access to an injured workman therein.

Abstract: A valve and method for use with a tracheotomy tube is presented wherein a flexible diaphragm is located a predetermined distance from a valve seat, the diaphragm being sized to allow air to flow around its periphery in either direction responsive to normal breathing through a tracheotomy tube, and to evert into sealing engagement with the valve seat to block air flow out of the tracheotomy tube responsive to air flow above that present in normal breathing. The diaphragm is in one end of a first barrel and the valve seat is in a second barrel sized to be inserted into the first barrel around the periphery of the diaphragm. Threads are provided between the barrels for adjusting the distance between the diaphragm and the valve seat by rotation of the second barrel within the first barrel. The valve may be inserted into a flexible base having a flexible flange for attachment to the paratracheal skin around the stoma of the patient. A shower shield and filter are also presented for use with the valve and base.

Abstract: A bracket is provided for attaching an outdrive auxiliary motor to a motor boat. The auxiliary motor functions as a source of emergency power and the bracket enables mounting of the auxiliary motor in place without impairing the maneuverability of the boat either under its normal source of power or its auxiliary source.

Abstract: A writing instrument in a conical configuration is provided which is less easily misplaced and which can be placed in a position of vertical stability if desired. The surface areas of the writing instrument are well adapted to display decorative or promotional indicia of a number of different types, or a combination of both.

Abstract: A construction for valve stems for vehicle tires is provided which fits them to accept quick connect and disconnect connectors. The stem is equally functional with quick connect connectors of different sizes and provides a protective covering for the entrance to the valve stem which is quickly removed when the connector is to be affixed.

Abstract: A sewage treatment apparatus having an aeration circulation system for separating sludge from sewage wherein sewage is circulated around an outlet port shielded by a circulation guide member. The circulating sewage causes solid matter contained therein to move radially away from the outlet port so that liquid entering the outlet port is substantially free of solids.

Abstract: A writing instrument is provided which, by virtue of its conical configuration, provides an improved display area for decorative or promotional items, particularly those of a novelty nature.

Abstract: A unit for inflating a vehicle tire is provided which functions to transmit air only if the tire contains at least a predetermined pressure. A signal is also provided which will function either to notify the user that air is being transmitted, or in the alternative, that air is not transmitted because a predetermined pressure was not present in the tire.

Abstract: A transaction drawer assembly is provided for use in carrying out transactions through the wall of a building. The drawer assembly fits onto an opening in a building wall and attaches to provide an entry through which transactions can be carried out. The drawer accepts items brought to the building and delivers items outside the building so they can be removed therefrom.

Abstract: A method for reactivating carbon beds is provided which is applicable to carbon beds used in purifying industrial wastes such as filtering water recovered from sewage. The method involves first adding either hydrochloric acid or a hydroxide of an alkali metal to the bed containing some of the water. The water and hydrochloric acid or alkali metal hydroxide are thoroughly mixed to distribute the acid or hydroxide throughout the carbon bed. The mixture of acid or hydroxide and water is retained in the carbon bed for sufficient time to reactivate the carbon. Thereafter the acid or hydroxide and water are removed from the carbon bed.

Abstract: A folding scaffold support is provided which can be readily attached to walls and a plurality of which provide sturdy and safe support for a scaffold assembly. The assembly is sturdy and accepts workmen and materials so that work can safely be carried out on a structure to which a plurality of them is attached.

Abstract: An arrow rest for a bow is provided which includes a plate that has an arrow pressure point contact area which engages the side of an arrow shaft as it lies on the rest. The plate is not attached to the bow handle but is attached to a spring biased plunger which is movable toward the bow as the arrow passes. Only one plunger is present which is a part of a connection which connects the plate to a bow and includes an interlock for interlocking the rod member to the remainder of the connection to restrain the rod member from rotating motion but permitting motion of the rod member and the arrow rest and arrow pressure point contact area in and out with the spring biased plunger. The interlock and the connection having longitudinal axes that are substantially coextensive with each other when the arrow rest is mounted on a bow.

Abstract: A remote control system for a derrick, having an encoder network for producing a plurality of differing electrical control signal frequencies at one location on the derrick and a discriminator network at a second location on the derrick for identifying each electrical control signal frequency produced by the encoder network. An electro-optical converter communicates with the encoder to convert electrical control signal frequencies to analogous light signal frequencies. A light tube communicating with the electro-optical converter transfers the light signal frequencies from the electro-optical converter to an optical-electro converter that communicates with the discriminator and reconverts the light signal frequencies back to their corresponding electrical control signal frequencies. The discriminator communicates with a plurality of output networks that correspond to operating members of the derrick and directs an identified control signal frequency to the output network associated with that frequency.

Abstract: A device for cooling inhalent gases including oxygen supplied to an air recirculator associated with an oxygen tent. The pre-cooled gas such as oxygen is supplied to an air recirculator such as a nebulizer unit where it is mixed with the recirculated air to replenish the oxygen content and reduce the temperature thereof.

Abstract: An impact type rock crusher having a rotor comprised of a plurality of stirrup type hammers adapted to swing through arcs of approximately 180.degree. between bumper blocks about pivot axes as well as rotating about the main shaft of the rotor. The grate positioned beneath the rotor through which the crushed material exits may be moved uniformly radially with regard to the rotor to an alternate grate position to vary the clearance between the hammers and the top surface of the grate. The overall design of the system reduces the height of the apparatus, and the apparatus may be made portable for movement from one location to another.
