Abstract: Apparatus and a method for applying coextensive lines or dots of an adhesive comprising an airless, solenoid-operated, adhesive spray applicator having a plurality of individual applicators within a single housing including a flow distribution arrangement, and a transverse, internally-mounted filter. The filter may be removed and replaced without disturbing the flow lines. Virtually any spray pattern may be applied by staggering rows of applicators and electronically controlling the operation of the individual applicators.

Abstract: A cloth tentering device wherein the tentering force for spreading cloth is produced magnetically between a permanent magnet member accommodated within a tubular cloth or engaged with the selvages of a flat cloth and rows of electromagnets in position separate from and parallel to the cloth. The tentering force can be freely adjusted in the course of the tentering operation by controlling the energizing current of the electromagnets.

Abstract: Compression hip screw apparatus comprising a lag screw, a hip plate, a compression nut and a locking assembly. The lag screw is inserted through the barrel of the hip plate after the hip plate is installed which eliminates the need to find a lag screw buried within the femur. Keyless construction further aids assembly. The locking assembly frictionally locks together the lag screw, the hip plate and the compression nut.

Abstract: A combination layout tool for aiding in the installation of a towel bar, a toilet tissue paper holder (sanitary paper holder), a soap dish, a toothbrush holder, or other like device comprising an elongated frame member having templates uniquely positioned thereon including level means, horizontal measuring means, and vertical measuring means.

Abstract: A harness for a horse and sulky comprising a saddle and an elastic girth and a method for attaching the harness to the shafts of a sulky. The saddle includes a bearing strap extending down the sides of the saddle and attaches to each end of the girth. The bearing strap is secured to the top of and at two locations on each side of the saddle. A sulky shaft loop is attached to the bearing strap between the saddle attachment points. A tie down strap attached to the top of the saddle and extending down therefrom is wrapped around the sulky shaft passing through each shaft loop and is tightly secured to the top of the saddle, pulling and securing the shafts and the shaft loops in an upward direction. The shaft loops are adjustably positioned on the bearing straps. A safety strap is loosely fitted to the elastic girth and wrapped around the sulky shafts with slack therebetween.

Abstract: Disposable irrigation and aspiration apparatus is disclosed for use during extracapsular extraction of a cataract from a person's eye. A separate handpiece is provided to allow the surgeon to apply only irrigation flow to the eye during the operation. The irrigation-aspiration and irrigation handpieces are connected by a valve to give the operating surgeon his choice of instruments without changing the rate of irrigation flow. The outer surfaces of both handpieces are obstruction free to give the surgeon a high degree of preciseness and maneuverability.

Abstract: Navigational apparatus adapted for interfacing between a Loran C receiver and an auto pilot is disclosed. The apparatus includes a reader for reading course error which is displayed on the readout panel of the receiver, a controller for inputting control signals to a vessel's auto pilot, which control signals direct the auto pilot to sheet straight ahead, correct left or correct right, and a computer for activating the controller in accordance with the data sensed by the reader. An audible alarm is included to alert a vessel's captain of a malfunction or an extreme off-course error so that the captain can manually effectuate any necessary corrective actions.
