Abstract: ABSTRACT OF THE DISCLOSURE        Dictate station apparatus for use with a multiple number of remotely-situated dictation recording machines.          The dictate station apparatus is selectively manually switchable for connection with any of the recording machines, so that a dictated message can be transmitted . to a selected recording machine from the dictate station.   When a control member at the dictate station is operated by termination of desired message dictation, the previously-actuated recorder switch is automatically released so that a manual selection of a recording machine must again be made before a subsequent dictation operation can be initiated.  Release of a previously-actuated recorder selection switch may be accomplished in response to hang-up of a hook switch associated with the dictate station.

Abstract: PRESSURE VENT-SEALED PRIMARY AND SECONDARY ALKALINE CELLS     Abstract of the Disclosure An extrudible hot melt adhesive material is utilized in a low cost vent for an electrochemical cell to relieve abnormal pressure formed during improper use of the cell.  The extrudible hot melt adhesive mater-ial is suitably joined or bonded to a member used to provide a cell top, and covers and fills a vent hole formed in the member.  Material is ex-truded through the vent hold by abnormal pressure to open the vent hole and allow the abnormal pressure to be released through the opened vent hole.  The venting pressure can be predetermined by varying vent hole di-meter, amount of adhesive, and the composition of the filler adhesive material with respect to viscosity.

Abstract: Abstract Flexure-pivots for providing a resilient restraint that opposes relative angular displacement between two members are known in which the resilient restraint is provided by two flat springs which are each held at one of its ends to a first rotatable sleeve carried by one member and at the other end to a second rotatable sleeve coaxial with the first and carried by the other member. Such flexure-pivots are difficult to manufacture accurately and have the disadvantage in that any debris accumulating between the sleeves can cause friction between the members and damage to the assembly.     According to one aspect of this invention pairs of pins are carried by both members and each spring is secured at one of its ends between a pair of pins of one member and at its other end between a pair of pins at the other member. According to another aspect of this invention the flexure-pivot is manufactured by securing four pairs of pins at one end to one member, securing each spring at each end between a pair of pins, securing the four pairs of pins at their other ends to the other member, and cutting through each pair of pins such that each  spring is secured at one of its ends between a pair of pins of one member and at its other end between a pair of pins of the other memeber.  Such flexure-pivots require only component parts that can be manufactured simply, produce an accurate location of the springs, and have an open form of construction which prevents any build up of dirt or debris in the flexure-pivot during manufacture or use.

Abstract: Abstract A bag stacker useful for plastic bags having a fence for stopping forwardly projected bags, raisable to permit a completed stack to move forward, a conveyor passing beneath the fence, a clamp moving with the conveyor to draw the completed stacks forward beneath the fence and a bag support arranged to assume, when the clamp engages a completed stack of bags, a position rearward of the fence, to receive and support bags arriving subsequently, this support being movable forward of the fence to disengage from accumulated bags.  Pre-ferably fingers extend below the fence and have trailing ends movable between raised and lowered levels and from a rearward position in which the ends extend rearwardly beyond the fence. These fingers move to the forward position prior to raising the fence and to the rearward position when the fence is raised and before the support is drawn forward of the fence, to insert the finger ends into the space between the clamp and support and thereby between completed and newly forming stacks. The support joins the clamp in a narrow edge facing incoming bags; the fence is counterbalanced, preferably free floating down, and rests lightly on the conveyor or stack; and the fence is mounted on rotary arms, preferably a parallelogram, pivoted to the supports to carry the fence close to the conveyor in bag-stopping position over the range of vertical adjustment.  The conveyor and clamp travel in parallel paths driven by an adjustable stroke rack with a clutch enabling reverse motion only of the drive belt for the clamp motion of the rack.

Abstract: PRINTED CIRCUIT BOARD PROTECTOR by John H.  Morgan ABSTRACT OF DISCLOSURE   Printed circuit boards are moved in a conveyor with the underside of flat boards spaced a prescribed distance above the top surface of a rotating cutting disk.  In order to protect the circuit patterns on the underside of the board and the board itself, a V-shaped wheel is loosely rotatably supported on a shaft with the wheel being in front of and orthogonal to the cutting disk.  The height of the wheel is adjusted such that the uppermost point on the circumference thereof is in the line of travel of the boards.  Movement of a board that is bowed downward in the direction of the disk causes the wheel to roll on the underside of the board and to raise the board above the top of the cutting disk.  In this manner, the underside of warped circuit boards is maintained at least a prescribed distance above the top surface of the cutting disk as the board moves over the leading - cutting edge of the latter and component leads are trimmed thereby.  Weak compression springs on either side of the wheel allow it to move sideways when it contacts a component lead.  The spacing between the wheel and the front edge of the cutting disk is also adjustable.
