Abstract: A self-deploying instrument assembly includes a plurality of instruments for example hydrophones, mounted on a flexible sheet. A series of resilient rods extend from one side of the sheet from positions spaced around the periphery thereof to a hub. The resilient rods are deflectable laterally inwardly with consequent folding of the sheet to place the assembly in a storable configuration smaller than its normal operative configuration. A suitable container for storing the instrument assembly is also described.

Abstract: A tone detector is connected or otherwise associated with an outgoing telephone trunk line adapted to be included in a toll path. One or more frequency or tone signals are sent over the trunk line for signaling and control during a toll call. If these tone signals appear at a point on the trunk line where the toll call remains under the control of d.c. signals, they must be fraudulent since there is no preceding equipment which is adapted to send valid tone signals. Therefore, a tone detector may be connected to that point in order to drop or otherwise block any calls during which the fraudulent tone signals appear. The toll fraud eliminator is particularly -- but not exclusively -- useful for preventing employment of a "blue box" during toll calls. The tone detector uses two multivibrators which operate at an upper and a lower threshold frequency respectively.

Abstract: The invention provides a bypass around virtually the entire periphery of a piston in a two cycle engine without substantially increasing costs or obsoleting production tooling. This is done by reshaping a cavity formed inside an engine casting to enlarge the crank case opening and to provide three oppositely displaced bypasses. The fourth side of the piston is open to the exhaust port. Therefore, virtually the entire perimeter of the piston is bypassed to greatly increase power by improved breathing.

Abstract: The invention provides an improvement over my earlier U.S. Pat. No. 3,573,783 whereby different types of sensors may be indiscriminately intermingled, intermixed or otherwise used together simultaneously, in the same proximity sensing systems. An antenna sensor may be used when line of sight detection is not appropriate. A photosensor may be used when line of sight detection may be used. Both types of sensors may be used simultaneously, or each may be used separately. The invention is broad enough to enable simultaneous use of almost any other types of sensors. This intermixture is achieved by use of a balanced bridge-like circuit which may be unbalanced either by an intrusion, movement, or exit or any person or object in the field of an antenna or by a snap-action-like sensor, such as a photocell, for example.
