Abstract: A tape cassette having a feed reel and a takeup reel with tape on the reels and a mounting cassette casing for enclosing the feed reel, the takeup reel and the tape. The mounting cassette casing having an exterior perimeter with a permanently removable nonreattachable blocking physical structure affixed to and protruding beyond the exterior perimeter of the mounting cassette casing to break upon insertion in a tape cassette apparatus unable to receive the permanently removable nonreattachable blocking physical structure revealing an altered appearance.

Abstract: A cathedral ceiling beam support combination of identical first and second elongated support elements each extending along longitudinal axes thereof, each having opposite first and second ends and having intermediate structure extending along an imaginary upright plane between and interconnecting the first and second ends, pivot structure and thereof pivotably connecting the first and second support elements through the intermediate elongated structure, each of the first and second support elements further including a laterally-extending flange having a downwardly-facing support surface adapted to press against a surface of a support beam, and beam-attachment structure and mechanism thereof on the laterally-positioned flange for securing the laterally-positioned flange to a support beam, the laterally-extending flange and the downwardly-facing support surface each extending at an angle of about 90 degrees relative to the upright plane, the beam-attachment structure including a plurality of through-space apert

Abstract: An additive for, a method of adding thereof to uncured mixes for and resulting cured cement-type concreations such as cured embodiments of concrete, marcadam, and roof-top shingles each exhibiting improved heat and freeze-thaw durability resulting from reduced efflorescence and stability against sun ultraviolet light exposure.

Abstract: An elongated narrow bulk delivery and depositing bouyant conveyor belt device is operable to shore up bridges, docks and/or piers in environments having operating space confined by low overhead and narrow berths between adjacent spaced apart pilings. The bouyant conveyor belt structure is alternately extendable and retractable in each of shallow and deep water. The bouyant conveyor belt structure is stabilized by one or between two linear axially extending substantially parallel sides of spaced apart floating platform barges. The barge(s) typically mount hopper and vibratable chute structure receivable of bulk typically rip rap fill material and feedable thereof onto the bouyant conveyor belt structure, thereafter deposited by a revolving of the conveyor belt structure.

Abstract: For specialized use to secure reliable standardized complete distribution or solution of aggregate mixed into a liquid diluent, a vessel having an interior hemispherical concave bottom having extending upwardly centrally from the concave bottom an arcuate conical member having upright concavely-shaped circumscribing sides. The vessel is taken in conjunction with a stably mounted mixing structure having a downwardly-extending shaft and mixing blades thereof. The shaft on a lower portion thereof supports balanced mixing blades extending radially outwardly from the mixing shaft. The mixing blades are positioned to be substantially spaced below a predetermined liquid level of liquid diluent containing a dissolvable or suspendable aggregate and to be substantially spaced above an upper end of the centrally upwardly arcuate conical member.

Abstract: A visually displayed message is repeated by reinitiation of an electronically progressively displayed message prior to the completion of the initial message while the initial message continues to move along the traveling path of observing persons moving in a common direction. The reinitiation of the message allows following observing persons moving in the common direction to see the beginning and remainder of the visually displayed message even though they could not see the message when forwardly located observing persons saw the message. The reinitiation of the visually displayed message occurs after a predetermined amount of time occurs from the initiation of the visually displayed message but before completion of the visually displayed message.

Abstract: A crawl swim exerciser includes a substantially horizontal elevated beam supported on and between spaced-apart head and foot supports, supported above a supporting substrate supportable of lower ends of the head and foot supports, with a roller mechanism being supported on and rollable along the elevated beam. Supported on the roller mechanism and slung below the beam is a support harness positioned to intermittently suspend a person's horizontally-positioned body lengthwise in a swim-position substantially lengthwise parallel with the beam while leaving legs and arms of a suspended person substantially free for making swimming leg kicks and swimming arm strokes.

Abstract: For system providing a storage and feed source of a particular liquid, and providing a conduit flow of one or more lines to one or more outlet valves separately controllable and operateable and concurrently controllable and operateable for simultaneous flow through any one or more combinations of the plurality of outlet valves, a computer mechanism for separately measuring and storing separately time of flow for each separate one of outlet valves and for each of diverse possible combination of concurrent operations of the outlet valves, and for the computer when activated to do so, to cause a repeat flow for any one of stored one of the outlet valves or for any stored combination thereof.

Abstract: A portable toy-assembly set that in a disassembled state is of a sufficiently miniature size as to be transportable by a child and assembled by a child, as water tank-like vessel having a sufficiently large upper water addition opening as to enable a child to add water thereto, drainable therefrom by a lower positioned drainage port connectable by disassembled joinable transparent conduits, with water-head pressure providable by disassemble support structure joinable with the tank-like vessel to support the tank-like vessel at selectable elevation. The conduits are connectable to a water-drivable accessory. A handle is mounted on the tank-like vessel or a vessel lid secureable to the tank-like vessel, enabling a child to more easily transport the portable toy-assembly set.

Abstract: A composite of an audio and/or video recorder mounted and securable on a handgun holster having a holster-mounted recorder-activation switch activatable of the recorder upon withdrawal of the handgun from the holster, remaining activated until return of the handgun to the holster. Other weapon holsters also each with a recorder activation switch in each holster are activateable when the weapon is withdrawn, mounted in parallel electrical circuitry with the handgun-activation switch, for additional weapons such as mase and a baton.
