Abstract: ABSTRACT OF THE DISCLOSURE       A device for holding a slider in position for threading onto a slide fastener chain includes a housing having a support surface for supporting thereon a slider body upside down, and a slit receptive of a pull tab hanging from the slider body.  A lever has a pair of juxtaposed first and second arms disposed one on each side of the slit, there being on the first arm a locking projection movable into and out of the slit. The lever is pivotable in the housing between a slider-holding posi-tion and a slider-release position.  The second arm extends beyond the first arm to such an extent that as the slider is placed on the support surface, the second arm is pressed downwardly by a hoke of the slider to cause the lever to be pivotally moved to the slider-holding position.  When a pull is exerted on the slider during the threading of the fastener chain through the slider, the second arm is brought into contact with the slider body, thus preventing the lever from being pivotally moved to the slider-release position.

Abstract: ABSTRACT OF THE DISCLOSURE       A circuit is provided for regulating the application of power to a load which is relatively insensitive to rapid power fluctuation of the type exemplified by typical AC line sources. In one embodiment, an AC line source is applied, via a full wave rectifier, at a controlled rate to a tungsten lamp whose operation is controlled by a transistor switching network.  The transistor operation, in turn, is controlled by comparing a portion of the rectified signal with a signal proportional to the light output of the lamp.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of minimizing the effect of parasitic currents in secondary batteries having a plurality of cells connected electrically in series and a common electrolyte in communication with the cells is described. Specifically, the parasitic currents flowing through the battery cause a cell imbalance over the charge/discharge cycle.  This cell imbalance is minimized by first separating the cells of the battery into two equal groups. Then the battery is charged with the two groups of cells connected electrically in series  and subsequently discharged with the two groups of cells reconnected electrically in series in an inverted sequence.

Abstract: FORCE TRANSDUCER FLEXURE WITH CONDUCTORS ON SURFACES IN THE NEUTRAL BENDING PLANE                        Abstract A flexure in a force transducer, as an inertial guidance accelerometer, for securing a force sensitive element to a mounting base includes one or more flexure sections having one or more recessed surfaces which are substantially coincident with the neutral bending plane of the flexure.  Electrically conductive coating on the recessed surfaces provide electrical connections to components located on the force sensitive element.  The conductive coatings on or near the neutral bending plane of the flexure sections minimizes bending moments caused by stresses set up between the conductive coatings and the flexure which may in turn lead to bias errors.  At the same time, the flexure configuration provides for the desired strength and spring rate for the force sensitive element.

Abstract: STORED CHARGE INVERTER CIRCUIT WITH RAPID SWITCHING            ABSTRACT OF THE DISCLOSURE       An inverter circuit having two pairs of transistors, the transistors of each pair thereof being connected in series to alternately and repetitively apply electrical energy to an inductive load such as a fluorescent lamp.          A square wave voltage is applied in opposite phase to electrodes of a first transistor of each pair thereof for rendering them alternat?y  in condition for conduction and nonconduction. Each time a first transistor of one pair thereof becomes nonconductive, current in the inductive load reduces and an inductively induced flyback voltage is generated therein, which voltage is applied to the base electrode of the second transistor of the other pair thereof for creating a stored charge which turns on this transistor and keeps it on during the half-cycle, whereby the pairs of transistors are alternately turned on and off for applying alternating current through the load.  Rapid discharge circuits are provided for the removal of residual stored charges.

Abstract: CLOSURE AND CONTAINER NECK STRUCTURE THEREFOR              ABSTRACT OF THE DISCLOSURE         This relates to a neck structure on a domed container end for receiving a thermoplastic material closure.  It particularly relates to containers having very thin walls on the order of 6-9 mils and wherein the container is formed of a metal having a grain which generally defines a fold line.  In order to avoid undue deformation of the lower part of the usual ring which receives the closure body, the domed end immediately adjacent an encircling ring is provided with an upstanding bead which is shock absorbent and functions resiliently to reinforce the lower part of the ring and to restore it to its original configuration after the body of the closure has been pressed through the ring.  Further, the closure is provided with a depending skirt which is circumferential-ly aligned with the bead and slightly axially spaced there-from so that when an undue load is placed on the closure, that load may be primarily transmitted, after initial deflection of the neck ring, to the domed end through the closure skirt and the bead.  This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

The use of the metal oxides in the resistor compositions surprisingly improve TCR (tem-perature coefficient of resistance) particularly in high resistance ranges and bring the TCR close to zero.  In addition to the effect of improving TCR, the metal oxides increase resistance and improve noise and VCR (voltage coefficient of resistance) proper-ties.

Abstract: ABSTRACT OF THE DISCLOSURE           System for testing pneumatic tires.  A tire (43) that  revolves  under  a  load  is  deformed  at  the bottom portion (47)  in which it meets the roadway (45).  Such a deformation results in the tire (43) having an effective rolling radius RE that is shorter than the radius RN it has while static and/or unloaded.  According to the invention, tires  (57)  are  tested  by  determining  their  effective rolling radii RE.   When tires  (21),  (23)  having similar effective  rolling  radii  RE  are  used  on  an  automotive vehicle 11, the undesirable torque steer effect is thereby reduced.

Abstract: Abstract APPARATUS FOR SEPARATING BAG   ENDS DURING MANUFACTURE           A pair of specially designed suction wheels are preferably placed after the glue applicator on a known pinch bottomer bag-making machine.  During manu-facture, paper bags are guided horizontally through the machine by a conveyor forming part of the machine. With this arrangement, one of the suction wheels is placed under the bag, and the other wheel is placed over the bag in line.  As each bag is moved by the conveyor, both suction wheels axe brought into motion like a rolling operation.  Each wheel has a shaft with a hollow channel going to a suction cup at the periphery of the wheel.  The number of suction cups around the circumference of the wheel could be any amount.  In a preferred embodiment, there are 12 equally spaced suction cups.  A vacuum pump with a hose is connected onto the shaft.  The pump draws air through the channel which comes from a suction cup so that, when the bag comes into the vicinity of the suction cup, the cup sticks on the bag layer. Because the bag is moving, the suction cup travels with the bag in the same direction. This action takes place simultaneously with both wheels. By doing so, the two layers of the bag cling to the suction cups.  By making a radius, up and down, the bag opens.
