The connector includes a pair of opposed members with a plurality of recesses located on the mating faces of each of the opposed members for receiving and clamping about the crossbar.

Abstract: A vertical blanking interval standardizer circuit detects the vertical synchronization interval of a video signal and generates a vertical block sync pulse which replaces a serrated vertical sync signal in which the pulse spacing has been modified in a non-standard manner. An early control pulse existing from the beginning of the vertical blanking interval until the trailing edge of the vertical block sync pulse and a late control pulse existing from the trailing edge of the vertical block sync pulse until the end of the vertical blanking interval are generated. The early and late control pulses pre-bias an amplitude limiter transistor such that the transistor is reverse biased by signal components during the vertical blanking interval which exceed a selected blanking level. In this manner, pulses occurring during the vertical blanking interval which have a gray or a white level are blocked and replaced by the selected blanking level.

Abstract: A drill and probe mechanism is adapted for use in grain bins and extends down deep into the body of grain to either retrieve a grain sample or deposit fumigation pellets. The drill portion of the mechanism includes a hydraulic pump providing power for a reversible hydraulic rotary head and separate screw. Lengths of drill string connect to the rotary head and the screw pushes the rotating drill string downward into the body of grain. A probe connected to the end of the drill string includes a tubular container body with doors that are opened and closed by selective clockwise and counter-clockwise rotation of the drill string. Various types of probes are utilized, including one that merely collects grain for sampling and another that dispenses fumigant pellets.

Abstract: A vehicle repair and alignment rack for correcting and aligning misshapened vehicle frame and body portions comprises a rack structure having a vehicle supportive upper surface and a lower surface with opposite side rack portions having inner and outer flanges joined together to form a central opening, whereby a vehicle straddles the opening for work access to the vehicle underside. Front and rear supportive legs are affixed to the rack structure for elevation above a floor surface and have power fluid rams operatively connected thereto for folding the legs and lowering the rack structure to the floor to facilitate positioning a vehicle on the rack. Force supplying members are affixed to the rack structure and are easily movable therearound so that they can be selectively positioned to exert pulls on substantially any part of the vehicle.

Abstract: Electrical contact probes for use in providing electrical contact between diagnostic equipment and an electrical device to be tested are provided. The probes disclosed herein are particularly suitable for use where contact sites are spaced relatively close together. A structure is disclosed, usable for a plurality of probe designs, including two-component and three-component contact probes, which enables the probes to be mounted by a variety of methods. Generally, the methods of mounting disclosed are enabled by the positioning of a mounting flare on the contact probes. Also shown is a three-component contact probe design that is particularly suited for use in long stroke applications, wherein the contact probe generally comprises an outer cylinder member, an internally received barrel, and a movable probe member. This latter member includes a relatively narrow shaft portion which slidably engages the barrel member, within the cylinder member.

Abstract: Mops and process for making closed or uncut end mops particularly using single ply cotton yarn having a high degree of twist. The yarn is processed through a fringe making machine into lengths of pre-sewn fringe and the high twist yarn tends to bunch together in thick, ropy masses of yarn strands. The fringe is affixed to mop backs to form a mop, and the mops are then soaked in a high temperature water bath until the ropy yarn strands relax, straighten and separate. The mops are rinsed and transferred to a high temperature hot air dryer and dried until the separate yarn strands twist about their looped ends to form separate, individual doubled ply yarn strands with uncut ends.

Abstract: A registration system for flexible printing plates includes a drill apparatus and a registration table which, used in conjunction, makes registration and mounting of flexible printing plates on plate cylinders relatively quick and easy. The drill apparatus includes a table with spaced, opposed drills slideably mounted on tracks in the table to accommodate different plate widths. The registration table includes a guide against which the plate cylinder is positioned and a slideably mounted plate mounting bar to which the flexible plate is pinned. The plate mounting bar is swept parallelly toward the cylinder guide and the plate rolled on to the cylinder, and adhered by double sided sticky tape. The pins affixing the plate to the mounting bar are removed and the remaining plate material rolled on to the cylinder. The process ensures that a selected longitudinal axis of the plate will be in registration, or aligned, with the longitudinal axis of the cylinder.

Abstract: Mops and process for making closed or uncut end mops particularly using single ply cotton yarn having a high degree of twist. The yarn is processed through a fringe making machine into lengths of pre-sewn fringe or processed through a wet mop making machine and the high twist yarn tends to bunch together in thick, ropy masses of yarn strands. The fringe is either affixed to mop backs or affixed together in the middle to form a mop, and the mops are then soaked in a high temperature water bath until the ropy yarn strands relax, straighten and separate. The mops are rinsed and transferred to a high temperature hot air dryer and dried until the separate yarn strands twist about their looped ends to form separate, individual doubled ply yarn strands with uncut ends.

Abstract: Multipurpose concrete form panels are constructed using cross stiffener members for resistance to deflection under load. Each of the cross stiffener members is formed of a base strip of metal with a pair of parallel ribs of hat section extending therefrom and joined to opposite side rails of the form panel. Bores for connecting pins extend through the side rails to join the panels side by side to form a wall or, using a corner form, to form a column. Bores through the side rails are positioned between the cross stiffener members and between the ribs in each pair of ribs for joining the side rails together with continuity of the cross stiffener members for maximum dispersal of stress. Holes for wall ties extend through the face of the form panel and between the ribs in each pair of ribs. Fasteners for the ends of the wall ties engage the pairs of ribs to disperse localized stress.

Abstract: A multiple parameter doppler radar system transmits a radar signal which is alternated between a first and second frequency toward a target. The doppler shifted signals reflected from the target are received and processed to derive a pair of doppler signals related respectively to the first and second frequency signals. The frequency of one of the doppler signals is measured and scaled to a target speed. The phase magnitude between the two doppler signals is measured and scaled to a target range. The phase lead/lag relationship of the two doppler signals is detected to determine if the target is moving toward or away from the radar system. The components of the system are controlled by a microprocessor which is programmed to perform quality determinations on the data derived from the signals to assess the reliability of the data even in a multiple target environment prior to displaying the parameters of target motion.

Abstract: An aspirating aeration and liquid mixing apparatus is positioned in a body of water and includes a motor driven propeller positioned within an intake duct and driving water through a nozzle. A plenum with an air intake pipe extends about the nozzle. The nozzle has ports with ramps thereover to provide a constriction for aspiration. The ramps are spaced annually about the interior of the nozzle with channels between the ramps. As water passes through the nozzle, a low pressure zone is created immediately downstream of the constriction to draw air through the ports, the plenum and the air intake pipe for aeration of the water. Large size materials which could otherwise clog at the constriction pass through the channels substantially unimpeded.

Abstract: A remote control unit integrator console includes a console tray to hold a plurality of infrared remote control transmitter units of various sizes and shapes. The tray includes a front hood which houses a mechanism for transferring infrared signals from the control units toward the appliances to be controlled. In one embodiment the infrared transfer mechanism includes a set of reflectors capable of efficiently reflecting infrared energy. In another embodiment, the infrared transfer mechanism includes infrared photo detectors connected to amplifiers which drive either a set of infrared emitters positioned in a diverging array or a single infrared emitter mounted in such a manner as to be pivotable. In still another embodiment, the coded infrared signals from the infrared remote control units are converted to radio signals which are received and reconverted to coded infrared signals by receiver units close to the controlled appliances for control of the respective appliances.

Abstract: A vehicle alignment system uses transverse, longitudinal and vertical bars mounted on a vehicle and equating to X, Y and Z axes for establishing the dimensions of the vehicle, which dimensions are then compared to the vehicle engineering specifications. The transverse bars are connected to the underside of the vehicle and, to enable quickness and ease of transferring the alignment system between vehicles, quick connect fittings extend between the transverse and longitudinal bars. Additional supports extend between the longitudinal bars and a base surface. The system is arranged so that transverse bars in a path of entry and exit of the vehicle can be readily removed and the vehicle removed and replaced, while maintaining the alignment system substantially set up and ready for use. The process improves the speed of use of the system by substantially alleviating the dismantling previously required.

Abstract: Antimicrobial or bacterial static compounds are added to mops and mats to retard mildew and generally inhibit growth of undesired organisms, to prolong product life, and, to aid in reducing contamination of areas in which the mops and mats are used. For mops, an antimicrobial or bacterial static solution is set into the mop's cellulosic yarn fibers, through a heat activated setting process. In mats, the antimicrobial compound is generally incorporated into a backing, such as a vinyl plastisol based backing, used for the mats.
