Abstract: ABSTRACT OF THE DISCLOSURE         In a carrier telephone extension system for transmitting electrical signals between the telephone line 1 (Fig. 4) and one or more extension telephones 12 and 14 over the AC electric power line 10 available at a telephone subscriber's premises or other transmission line, that includes a main station 316 (Fig. 3) for processing signals between the subscriber's telephone line 1 and power lines 202 (Fig. 1), 10 (Fig. 5), 301 (Fig. 3) and one or more extension telephones 12, 17 of the system that plug into the power line, means 303 (Fig. 3) for encoding and decoding the signals that are transmitted over the power line between the main station 316 (Fig. 3) and extension telephones 204 (Fig. 3) of the system as an aid to eliminating inter-ference, or signals originating in other power line or transmission line carrier systems that have access to the same power line main and inhibiting eavesdropping. Thus, any of the extension phones of the system can be used at any location at the subscriber's premises where there is access to the power line or transmission line and interfering signals and eavesdropping are avoided. All of the extension telephones can place calls to the telephone line, answer calls from the telephone line and conference together in full duplex communication. Also, means are provided at the extension telephones for initiating a telephone line hold signal that is transmitted over the power line to the main station where the hold signal is detected and initiates con-necting a hold impedance across the telephone line. Further means are provided for two or more of the system telephones to communicate without going on the telephone line (Intercom), even while another system telephone is engaged in an outside telephone call and means are further provided for all telephones of the system to conference in Intercom.

Abstract: ABSTRACT   An adaptable material-spreading vehicle includes in combination a truck body frame, a rear-mounted engine on the frame above the rear wheels, a forward cab, a removable hopper positioned between the cab and the rear-mounted engine, and a conveyor running from beneath the hopper directly through the cab to a material spreader mounted forward of the cab in view of the operator, with the hopper and conveyor being removably mounted to the truck frame, such that the material spreader vehicle can be converted to some other use. In one embodiment, the cab is provided with a central channel through the floor to accommodate the section of the conveyor passing through the cab, with the cab being provided with sealable conveyor ports aligned fore and aft through which the cab-carried conveyor section is passed. In a preferred embodiment, the conveyor runs the entire length of the bottom of the hopper trough such that material is initially removed from the rear of the hopper, thereby providing that the majority of the weight of the dispensed material is as far forward as possible.

Abstract: METHOD FOR MAKING IRREGULAR SHAPED SINGLE CRYSTAL        PARTICLES AND THE USE THEREOF IN ANODES FOR                     ELECTROCHEMICAL CELLS     ABSTRACT   A method for making single crystals of metal or other crystallizing materials whereby powders of irregular shaped single crystal particles (as small as 325 mesh or about 50 microns) may be readily and economically made.  Said method comprises the steps of:  a) forming thin individual coatings on each of said particles such as oxides of metals on metal particles; b) melting the particle material within said coatings which function as individual particle crucibles;  c) cooling the melted particles within the coatings to form individual single crystals each within its own coating; and d) removing the coating such as by solvation with a solvent or by chemical reaction.  The single crystal particles conform to the original shape of the particles which may be irregular.  Such irregular shaped single crystals, such as of zinc, when used in electrochemical cell anodes enables the utilization of reduced amounts of mercury form amalgamation thereof without significant increase in cell gassing.

Abstract: ABSTRACT      A method and an apparatus for texture generation for a digital image generator of an aircraft flight simulator is disclosed in which (a selected two of the three) coordinates of each pixel of an image are inverse transformed to earth coordinates (112-124, in Figure 23) from which addresses are developed (126, 128 and 130) for accessing a texture table (132 and 134) to retrieve elements from which an appropriate pixel intensity is developed (140).  The table stores near (132) and far (134) texture, the far texture elements being interpolated to avoid a checkerboard effect, stores a limited number of texture types, the elements of selected texture types being combined (132 and 134) to develop additional texture types, and stores  levels of detail (degrees of filtering) the appropriate levels being accessed (126) to avoid aliasing (scintillation of a scene), adjacent levels being mixed (136 and 138) to provide smooth detail level transition.

Abstract: ABSTRACT OF THE DISCLOSURE A vertical coil for a television deflection yoke comprises a plurality of winding emplacements or layers wound in a shootback manner.  The abrupt change in wire direction following the shootback winding tends to cause displacement of the initial turns of the subsequent winding emplacements.  In order to prevent this displacement, the coil winding emplacements are wound with progressively greater winding angles so that the initial turn of each subsequent emplacement lies along the core surface and abuts the previous winding emplacements.  The presence of the previous emplacements obstructs and prevents movement of the initial wire turns of each winding emplacement which allows the coil to be wound without the need for winding shootback straps or core end rings.

Abstract: ABSTRACT OF THE DISCLOSURE    An insulated conductor such as an encapsulated electrical circuit is made by locating the circuit components in a preformed carrier with opposed flexible walls with an external, outwardly facing abutment in the shape of a conical opening through each wall.  The internal volume between the walls of the carrier is then filled with a hot fluid insulating plastic which also fills the conical opening forming a bridge between the openings.          The bridge is caused to cool and set first so that it contracts developing a lengthwise tension which draws the walls toward each other providing the formation of air space between the walls and remainder of the filling.

Abstract: ABSTRACT OF THE DISCLOSURE        An evaporator for refrigeration devices comprises a serpentine tube bundle having a plurality of spaced-apart parallel fins.  The tube bundle is arranged to provide sets of tubes in a staggered arrangement to increase the number of tube passes for the height of the evaporator and space the tubes apart to improve efficiency of air flow patterns over the tubes to enhance heat transfer.  The fins are made of ultra-thin material of a thickness less than 0.20 millimeters.  The fins have an embossed pattern to reinforce the fins through which the tubes extend in appropriately shaped apertures.  Due to the thinness of the fins, portions of the fin walls are displaced by inserting the tubes in the apertures to ensure metal to metal contact between the fin and the tubes.  The embossed pattern is such to induce turbulence in the air flowing over the fins and tubes to considerably increase the efficiency of the evaporator unit.
