Abstract: A fluid container assembly including one large, relatively narrow container having an orthogonally shaped recess or depression in a wall portion thereof, and two small fluid containers nested within the recess. The recess has means therein engagable with mating means on each of the small containers for retaining the small containers within the recess against accidental dislodgement and so that the external walls of the containers are flush. Each fluid container is provided with a tamper indicating insert such that tampering renders difficult withdrawing fluid.

Abstract: A liquid sampling, metering and transfer valve assembly for providing plural dilutions of a single liquid sample comprising a pair of outer stationary elements sandwiching a rotatable element, the rotatable element carrying precise volume segmenting passageways, the outer elements carrying counterpart passageways for communicating to the exterior of the valve assembly, one outer element carrying loops each for storing a precise volume of diluent and the other valve elements carrying through passageways for communicating to and from said respective loops. A continuous body of sample is introduced into the valve assembly along a path through a pair of the segmenting passageays and a pair of aliquot portions isolated from said parth. The rotatable element is operated to direct one aliquot along with the content of one loop to an exterior location for mixing. The other sample aliquot is retained.

Abstract: A solenoid operated pinch valve including a housing and a hollow molded body coupled to said housing by a snap-on connection, a solenoid coil assembly seated within the housing, a plunger accommodated within said solenoid coil assembly for axial movement relative thereto controlled by energization of said solenoid coil assembly and between a pair of positions, said plunger having an end portion extending from the housing into said body and an opposite end portion received within said solenoid coil assembly, the body having a circumferential flange capable of being seated on one end of the housing and a pair of inflexible arms extending from the body in a coaxial direction relative thereto, said arms defining a passage for receiving a conduit across the path of movement of said plunger, a first orthogonal slot and a pair of resilient arms extending to the opposite end of the housing and engagable therewith in a snap-on coupling. One end of the plunger carries a second orthogonal slot.

Abstract: Bellows pump and actuating apparatus for automatically aspirating biological sample fluid material into and through an aspirating probe from a source of fluid sample material, into and through a sample segmenting valve for passage through a counting device. A plurality of bellows members, each having an axis of compression and expansion, has one end mounted on a fixed member. Timing and stroke members are provided for actuating movement of the other end of the bellows members, which are free to be moved parallel to their axis. A positioning member positions the timing and stroke members coaxially of the bellows members at preselected times. A drive member moves the timing and stroke members parallel to the axis of compression and expansion of the bellows members. Photo-optical indicating members, cooperating with the positioning member, interrupts the drive to the positioning member when the timing and stroke members are coaxially aligned with the bellows members.

Abstract: A collection receptacle for receiving valuables which are contained in a box having a discharge opening whereby the box can be received within the receptacle, unlocked thereby, and then moved to a position so that the valuables therein are discharged into the receptacle. The door of the receptacle carries drive means engageable with the box to achieve the movement necessary for the discharging operation. A locking arrangement comprising a movable blocking member is associated with the receptacle, and this blocking member is moved into a blocking position relative to an arm associated with the door when the driving action is commenced. The blocking member is mounted on a rod which extends to the rear of the receptacle, and a mounting plate for the box at the rear of the receptacle is operatively connected to the rod to achieve movement of the blocking member into blocking position.

Abstract: A construction for securing valuables such as currency wherein the currency is deposited in a housing which removably holds a storage box for the valuables. The storage box is provided with a door which is normally locked in the closed position but which is unlocked and movable to an open position when associated with the housing. Movement of the door between open and closed positions is controlled by a pivotally mounted arm which is freed for movement when the storage box is located in the housing. The arm is controlled by a handle exposed on the exterior of the storage box, and the locking means provided determine the capability of handle movement. A separate acceptance receptable is provided for the discharge of valuables from the storage box into the receptacle. The operation of a separate storage box door is controlled by drive mechanisms associated with the acceptance receptacle, and the locking means of the storage box also determine the capability of movement of the drive means.

Abstract: A system for handling coins and the like which includes a storage housing having a discharge opening with the discharge opening being normally closed by a locked door. A coin transfer mechanism including a tubular housing is adapted to be attached to the storage housing and held firmly in place on this housing. A key structure is associated with the transfer mechanism whereby the door can be unlocked and pulled to an open position at which time the coins are discharged into a collection area associated with the transfer mechanism. The design of the transfer mechanism and the means for holding this mechanism in place on the storage housing prevent any access to the coins during the collection operation.
