Abstract: A motor and manual actuated switch includes a motor control circuit for controlling the motor to rotate in either a clockwise or counterclockwise direction to actuate a mechanical switch between the open circuit and short circuit states. The control circuit includes a capacitor coupled in series with the motor winding to form a series circuit and a control switch for connecting a source of d.c. power across said serial circuit when in a first position and a short circuit across said series circuit when in a second position. When the control switch is moved to the first position, the capacitor charges, causing a current to flow through the motor winding during the charge time, thereby causing rotation in one direction. When the control switch is moved to the second position, the capacitor discharges through the winding, thereby causing opposite current flow and shaft rotation.

Abstract: A multi-spectral reticle projector coaxially projects two separate reticles at different wavelengths through a single aperture by using a lens system including a dichroic lens disposed coaxially between the two reticles. The visible light is reflected by the mirror and passes through the lens system twice, while the infrared light passes through the mirror and passes through the lens system once. At the output of the lens system, the two reticle images are superimposed, collinated and coaxial.

Abstract: Aramid-reinforced elastomers, including rubber, in which the elastomer is reinforced with aramid in the form of short, discontinuous, fibrillated fibers, are disclosed. The fibers are composed of a trunk portion having a length of about 0.2-5 mm, a diameter of about 0.005-0.02 mm (5-20 micrometers), and an aspect ratio greater than 100, and numerous fibrils extending outwardly from the trunk and having diameters substantially smaller than the trunk diameter. The surface area of the fibers is from about 4 to about 20 square meters per gram, and is about 30 to 60 times the equivalent surface area of fibers in the form of rod having the same diameter distribution as that of the trunks of the fibers herein, but with no fibrils. The fibers are oriented. Incorporation of the fibers results in substantial increase in stiffness and modulus. Loading of aramid fibers is typically about 0.2-20 phr.

Abstract: A toy telephone having a telephone base, a telephone handset, and a cord extending between the base and the handset, the cord having first and second cord segments of preselected lengths, the first cord segment connected at one end to the base and the second cord segment connected at one end to the handset. Mating connectors at the free ends of the first and second cord segments releasably connect the cord segments to form a single continuous cord between the base and the handset that has an apparent length that is longer than the length of either cord segment and sufficiently long for play use. Upon application of a force in excess of that normally encountered in play use, the connectors allow the cord to separate into its component segments.

Abstract: An adaptor assembly for removably mounting a traction wheel that is a partially inflated conventional automotive or turf tire on a conventional automotive or trailer rim, to each of the driven wheels of a forklift. The adaptor assembly has a mounting assembly semipermanently attached to the driven wheel and a traction tire assembly including a spacer sleeve attached to the traction wheel. An anchor member extends through a bore in the spacer sleeve and threadably engages a central hole in the mounting assembly to anchor the traction tire assembly to the mounting assembly. Drive pins extending from the spacer sleeve engage small openings in the mounting assembly adjacent the central hole to transmit torque between the wheels. In one embodiment, the anchor member is hollow with an inner diameter larger than the hub of the driven wheel so that a protruding hub may be accommodated.

Abstract: The pressure containment device for containing pressurized gas within a Stirling engine is characterized by enclosing a drive mechanism housing with a cylindrical pressure hull having first and second ends whereby a portion of the drive mechanism housing extends through the first end of the pressure hull and the second end thereof, is rigidly connected to the drive mechanism housing. An o-ring is used to seal the connection where the drive mechanism housing extends through the first end of the pressure hull to allow small axial and radial relative motions therebetween. An output shaft extends along the axis of revolution of the pressure hull and is supported by front and rear main bearings and a thrust bearing, all rigidly connected to the drive mechanism housing. A rotating shaft seal, also connected to the drive mechanism housing, prevents pressurized gas from escaping along the output shaft.

Abstract: A video display terminal permitting substantially continuous scrolling of the display. Each character row of the display is stored in the display memory in a memory segment which also stores one or more parameter bytes associated with the character row. A first parameter byte portion indicates the number of the scan line on which the display of that character row is to commence during the current frame. A second parameter byte portion indicates the number of scan lines of that character row which are to be displayed during that frame. A memory address within the parameter bytes indicates the address of the memory segment storing the next character row to be displayed. This memory address is applied directly to the DMA controller.

Abstract: A telecommunication cable, and method of making same, is disclosed comprised of more than five S-Z twisted wire pairs having their twist reversals longitudinally staggered in a repetitive sequence of 1 to N longitudinally spaced positions. The wire pairs are bundled with any adjacent pairs having their twist reversals non-overlapped and staggered by no more than N/2 positions which limits S to Z coupling.

Abstract: A plurality of data entry terminals is connected to a microprocessor system which analyzes terminal data for display on a production CRT, intended to be located in a restaurant kitchen. Food items entered on the terminal are displayed with a corresponding symbol denoting a work station where such food item is to be prepared. As each item is prepared, the food preparer enters a display symbol to signify its completion. Upon completion of all items in a food order, the microprocessor system erases the order from the CRT. A separate CRT may be connected to the microprocessor system for use by a food expediter. As each order is completed by the food preparers, the order is visually displayed on the expediter CRT thereby alerting the food expediter to collect the items of an order in the kitchen so that they may be picked up by a waiter.

Abstract: A trenching plow and technique for its use, especially for forming a trench under water for receipt of pipe. The plow includes a frame with a tandem set of wheels at the front, and a share with mould boards mounted at the back of the frame. During trenching the frame always makes a positive angle with respect to the horizontal, and a soil furrow splitter is formed on the bottom of the frame. A pair of coulters are mounted to the frame in front of the share, each of the coulters raking forward at an angle of about 60.degree.-70.degree. to the horizontal, and the coulters being staggered along the length of the frame. The coulters also have a positive clearance angle with the trench side wall, and they extend to a depth about two-thirds the depth of the share. A trench having a depth of about 1.1 meters with side walls at an angle of about 60.degree. to the horizontal may be formed at a towing speed of about two knots, the trench being formed having constant cross-section and constant depth.

Abstract: A flow control valve with a valve closure element is provided having at least one annular resilient seat member and an annular flexible metal seat member positioned adjacent to it. The flexible metal seat is held in position by heat resistant gaskets and is biased against the resilient seat member. Upon the failure of the resilient seat to seal because of melting or deterioration caused by exposure to heat, the flexible metal seat member springs into position to provide a fire and heat resistant metal-to-metal seal with the valve closure element.
