Abstract: DIGITAL-TO-ANALOG CONVERTER     ABSTRACT OF THE DISCLOSURE A D/A converter is comprised of a string of resistors coupled to a voltage source with respective junctions formed between adjacent resistors, including a reference junction substantially at the mid-point of the resistor string.  Plural switches are coupled to the junctions and are selectively operable to couple a potential produced at a respective junction.  A subtracting circuit has one input coupled in common to a first set of the switches and another input coupled in common to a second set of the switches to subtract the potential coupled from one set from the potential coupled from the other set so as to produce an output analog signal.  A switch control circuit is responsive to a multi-bit digital signal for operating predetermined switches in both the first and second sets and thereby couple to the subtracting circuit the potentials which are produced at corresponding junctions on either side of the reference junction.              -i-

Abstract: ABSTRACT OF THE DISCLOSURE A serial-to-parallel converter receives serial data bits forming serial input words and serial word synchro-nizing pulses indicating the length of the serial input words.  A parallel clock signal is generated synchronously with an integer number of serial word synchronizing pulses. The input data is sequentially supplied via a direct data path to an output storage means.  A synchronous counter counts the received consecutive serial data bits and in response to each count a decoder sequentially enables one respective output storage means to store therein one data bit.  The stored data is released simultaneously from the output storage means in form of a parallel word in response to the parallel clock signal.  Means for changing the length of the parallel output word are provided.

Abstract: FASTENER FEEDER               ABSTRACT OF THE DISCLOSURE         A feeder for fastener is used to supply uniformly oriented, uncollated fasteners to a detachably mounted loading assembly so that the uncollated fasteners can be loaded into a magazine of the fastener driving tool.  The feeder includes a rotatable supply drum mounted on a base into which fasteners may be supplied.  Scoops along the inner wall of the drum scoop up a quantity of fasteners as the drum is rotated and supplies the fasteners to an orientation assembly. The orien-tation assembly receives the unoriented fasteners on a funnel-shaped trough which directs the fasteners toward a rotatable orientation roller disposed on one side of a fastener path.          The orientation roller has several notches or grooves that tend to jiggle or agitate the fasteners so that the fasteners are oriented in the fastener path with the heads of the fasteners lying on an orientation rail on the opposite side of the fastener path from the orientation roller.  The fasteners travel along the fastener path toward the loading assembly which has a loading path in alignment with the fastener path.  The drum and orientation roller are rotated by a single motor through a belt drive system having a plurality of pulleys such that the orientation roller can be rotated at a greater speed than the supply drum.  Once the fasteners are supplied to the loading assembly a photo-optical control is used to detect when the loading path is full of fasteners so that the motor can be turned off when no further fasteners need be supplied to the loading assembly.

The apparatus for pressure screening pulped fibrous matter comprises a cylinder-shaped housing complete with end cover plates, conduits for feeding the fibrous stock to be screened into the apparatus and for discharging the accepted fibrous stock and the rejects therefrom, a rotor in the form of a drum with end walls, and two identical screen members defining in conjunction with said rotor an annular space, the fibrous stock to be screened moving therethrough in two oppositely-directed streams, and pass-ages for communication of said annular space and said con-duits. In this apparatus the passages feeding the fibrous stock into the annular space between said rotor and screen members, terminate in a space defined by the end cover plates of said housing and the end walls of said rotor while in between said screen members there is located an annular gutter, its open side facing the rotor and the gutter it-self communicating with the rejects discharging conduit, the result being that the fibrous stock to be screened is fed for screening to the opposite sides of said housing, moving towards its central part while the rejects are be-ing removed from that same central part of the hous-ing.

Abstract: ABSTRACT         A tailgate loader of a truck or the like, the improvement of a load retention fence which comprises; a pair of elongated arms pivotally mounted on said platform at a side edge thereof at a point adjacent said inner end of said platform.  The arms are movable relative to said platform between a storage position in which they are upright and extend substantially parallel to the platform when the platform is in its storage position and a deployed position in which they extend upwardly and rearwardly from the inner end of the platform when the platform is in its deployed position.  Flexible side fence chains connect the distal end of each arm to an adjacent slide member of the lift mechanism so as to prevent rotation of each arm relative to the platform beyond that required for movement between said storage position and said deployed position of said arms.  Tie chains connect the distal end of each arm and the outer end of said platform, tie chains having a length so as to be taut when said platform is in its deployed position and the arms are in their deployed position.  The tie chains serve to automatically deploy said arms in response to movement of said platform between its storage position and its deployed position.  An outer fence is detachably mountable at the distal ends of the arms and extends transversely therebetween when said arms are deployed so as to form a load retaining fence at a substantial distance above the outer end of the platform when the platform is in its deployed position, said outer fence is detachable so as to be removable to avoid forming an obstruction when the arms are in their storage position.

Abstract: Abstract A machine for progressively roughing marginal portions of shoe bottoms comprises a shoe support (18) having toe support means (470) and a heel support arrangement including two sets of clamps (390, 392), one set (392) of which serves also as sensing means for sensing, by engagement with an off-set portion of the shoe last whether the shoe thus supported is a let or a right.  An inductance sensing device (610) associated with the second set of clamps (392) supplies a signal to control means of the machine, the signal being dependent upon whether the shoe is a left or a right.  The control means ensures that, in the operation of the machine, a roughing operation is carried out on the shoe bottom in such a manner that the inside waist region of the shoe bottom is traversed always in the same direction, regardless of whether the shoe is a left or a right (and of course similarly the outside waist region is consistently operated upon).  In this way, uniformity of rough as between left and right shoes can be achieved.
