Abstract: VOLTAGE CONVERTER                    ABSTRACT OF THE DISCLOSURE         A voltage converter for boosting the voltage and/or inverting the polarity of a DC voltage source having positive and negative terminals includes at least one series circuit of a capacitor and a diode connected through the latter with one of the voltage source terminals while the other end of the series circuit is alternately connected with the positive and negative voltage source terminals through a respective switching circuit, and an output is derived from the connection point between the capacitor and diode of the series circuit.  Such output may be applied, for example, through a peak-value rectifier, to one side of a load having its other side connected to the voltage source terminal opposite to that connected with the diode of the series circuit so that a voltage two times that of the source is applied to the load.  If the diode of the series circuit is connected with the negative terminal of the voltage source, the polarity of the voltage applied to the load is inverted.  If a second series circuit of a capacitor and diode and an associated switching circuit are combined with the first mentioned series circuit and switching circuit to provide an output of inverted polarity at the connection point between the capacitor and diode of the second series circuit, and the load is connected between such connection point of the second series circuit and the corresponding connection point of the first series circuit, then the voltage applied to the load may be three times the voltage of the source.

Abstract: ABSTRACT A cord gripping apparatus comprises a substantially cylindrical body having a threaded section and an inner wall which defines a bore section having a longitudinal axis substantially concentric with the longitudinal axis of the cylindrical body.  The cord mounted in the bore, and a sealing element in the bore is in contact with the inner wall and the cord to provide a seal between the body and the cord.  The cord is restrained against longitudinal displacement in the bore by an annular open-sided ring formed of at least two segments which define therebetween an opening for receiving the cord.  Hinge means join said segments together for relative pivotal movement  in a plane substantial-ly normal to the longitudinal axis of the bore, whereby the ring can open and close on said cord in a plane substantially normal to the longitudinal axis of the cord.  Camming surfaces are formed on the periphery of said two segments.  Rotatable means such as a nut has a threaded section en-gaging the threaded section of the body and a camming surface for engag-ing the camming surfaces of said two segments, whereby upon rotation of the rotatable means in one direction, the segments close to grip the cord.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus and method is disclosed for washing out the interiors of truck and trailer bodies.  A washer head is carried on an elongate boom which is mounted on a pedestal for traversing movement along a horizontal axis.  The boom is moved by means of a drive motor which is in engagement with a chain having its opposite ends secured to opposite ends of the boom.  The washer head includes a frame which is mounted on an end of the boom for pivotal movement between elevated and lower positions,  The frame is constructed in a four-bar linkage arrangement for movement through a lateral angle to accommodate any misalignment as the boom enters the trailer.  A cam engages a hoist are connected with the frame of the washer head, and a motor is controlled to rotate the cam for raising and lowering the washer head. The washer head mounts a brush which is operated as the boom withdraws from the trailer interior.  A series of spray nozzles on the washer head are connected through flexible hoses with conduits carried on the boom, and these conduits in turn are connected with flexible hoses which are supported on a floating linkage.  Photocells and limit switches are provided for controlling the operating functions in such a manner that the operator need only back the trailer into a position for initiating forward movement of the boom into the trailer as deter-gent is being sprayed.  The control system automatically withdraws the boom from the trailer as brushing and rinse spray action progress, and the operator then drives the trailer forward for completion of the washing cycle.
