Abstract: ABSTRACT OF THE DISCLOSURE           A brake control assembly for a chain saw has an operating lever provided with a hub portion alongside a housing of the saw and a guard portion adjacent a handle carried by the housing.  The hub portion is pivotally mounted on the housing allowing the lever to be moved fore and aft.  A brake drum associated with the drive-trans-mitting mechanism of the saw is engaged by a brake band when the lever is swung to a brake-on position.  The pivotal connection for the hub portion also supports an actuating plate for rocking movement independently of the hub portion.          There is a drive connection between the operating lever and the actuating plate which rocks the plate on the pivotal connection when the lever is moved fore and aft.  The actuating plate has a cam finger connected to one end of the brake band and the opposite end of the band is anchored to the housing.  A torsion spring tends to rock the actuating plate in one direction and urge the brake band into braking engagement with the drum.  The housing is fitted with a resilient latch which engages the cam finger to hold the brake band out of braking engagement with the drum.  The brake arrangement operates automatically when the lever is knocked forwardly and is reset in a normal brake-off posi-tion when the lever is pulled towards the rear of the housing.

Abstract: TELEPHONE CALL RESTRICTING APPARATUS            ABSTRACT OF THE DISCLOSURE         An apparatus for restricting telephone calls placed onto a telephone line by a telephone set, wherein an off-hook condition begins operation of the apparatus and energizes a control circuit which provides a condition in which a call can be placed onto the telephone line.  A disabling circuit responds to the control circuit and establishes a disabling condition on the telephone line which defeats a telephone call when it is of a restricted type.  In one embodiment, the off-hook condition starts a time delay at the end of which a prede-termined frequency is placed onto the line.  The occurrence of this frequency signal onto the telephone line disconnects all long distance telephone calls beyond a specified local zone.  In a second embodiment, each number entered onto the telephone line is counted, and when a predetermined count is reached the disabling circuit is operated to prevent further calling.  In a third embodiment, the telephone remains dis-abled after being placed in an off-hook condition, and all calling is prevented.  However at predetermined intervals, the telephone is enabled so that during each interval a respective number can be called.  The apparatus can include an override circuit for use by special preselected individuals for over-riding the disabling condition thereby permitting such special individuals to avoid the restrictions of the telephone calls.

Abstract: Abstract A tamper-proof cap for a container closure device for providing a vis-ual indication of any tampering and tampering attempts with the container closure device includes an annular body portion, a pull ring portion detachably joined to the annular body portion, a tear-out strip portion joined to the pull ring portion and a pair of connecting membranes disposed between the tear-our strip portion and the annular body portion. The annular body portion includes an enclosing wall, an inwardly extending lid section joined to a top edge of the enclosing wall, and an outwardly extending lip section joined to a bottom edge of the enclosing wall.  The inwardly extending lid section is annular in shape and defines a center opening.  The pull ring portion is detachably joined to the inner edge of this center opening by three reduced-thickness membrane sections which can be easily torn under nominal manual force.  The connection between the pull ring portion and the tear-out strip portion remains intact, yet as additional force is applied upwardly and outwardly on the pull ring portion in the direction of this tear-out  strip portion, the connecting membranes begin to tear , thereby separating the tear-out strip portion from the remainder of the annular body portion.  Once this strip portion is completely removed, the annular body portion is severed and it is then able to be manually removed from its secured position beneath the anchor ring which secures the closure device to the container.

Abstract: ABSTRACT OF THE DISCLOSURE      A container providing for the separate storage of two materials and the automatic admixing of the materials upon opening of the container.  A main container holds a quantity of a first material, such as carbonated water, and a separate compartment holds a small quantity of a second material, such as dipeptide flavoring.  In a first embodiment of the invention, a compartmented closure of the twist-on, twist-off type is mounted on the neck of a bottle-shaped container.  The closure includes a compartment extending into the container neck, having a hinged bottom closure with a lip which protrudes radially outwardly below the bottle neck.  As the closure is unscrewed from the bottle, the lip engages the interior of the bottle neck, causing the hinged bottom to open and thereby release the second material into the main container.  In a second embodiment of the invention, a bottle has a twist-on, twist-off type closure which has a compartment for the second material therein.  The compartment is stationarily positioned in the neck of the bottle, and the closure includes a movable piercing element which, upon unscrewing of the closure, pierces the stationary compartment to cause the release of the second material into the bottle.

Abstract: ABSTRACT            IMPROVED ELECTROSTATICALLY   DEFORMOGRAPHIC SWITCHES      This describes a dual electrode electro-statically deflectable deformographic switch. The switch can be driven by co-incidnet voltages and can be made to retain and store information. The switch can be used either as a display or a memory and has a number of engineering advantages, for it is a direct drive display which does not need either vacuum envelopes or electron beam drives. Furthermore, greater efficiencies can be realized and no refresh is necessary since the switch will operate in a standby condition.  Also only two volt-age levels above ground, i. e., a write voltage and a standby voltage, are required.  The switch will enable copiers to be directly driven by computers.     The switch can also be used as an optical waveguide transmit/receive switch or an accelerometer.
