Abstract: Abstract of the Disclosure Polystyrene pellets are continuously supplied to extrusion means which continuously forms an elongated element whose form and shape is stabilized by hydraulic cooling means through which the element is moved, following which the element is dried and heated and then supplied between heated pressure rolls along with a tape on one surface of which a coating has been applied and which includes a decorative film, the coating being in face contacting relation with a surface of the elongated element, the temperature of the pressure rolls and the velocity of the movement of the tape and elongated element therebetween being correlated in such manner as to cause a decorative film to be removed from the tape and deposited on the elongated element, following which the element and tape are engaged and transported away from the pressure rolls into a cutting station at which the element is severed into desired lengths.  If desired a second set of pressure rolls may be disposed downstream from the first pair of pressure rolls and may be utilized to apply a decorative film to another surface of the elongated element which is angularly related with the first surface, the elongated element being twisted so as to accommodate this operation with the second set of pressure rolls which are oriented similarly to the first pair of pressure rolls.

Abstract: ABSTRACT       A fireplace enclosure comprising a frame having two vertical side members and two transverse cross members extend-ing therebetween, two pairs of hingedly connected folding doors for closing off the space encompassed by the frame, and a pair of slide latches connected with elongate slidable handles on two of the doors respectively for conveniently selectively opening and closing the doors.  The frame includes a door stop in the form of a depending apron on the upper cross member, constituting a backing for the doors when they are in closed positions.  A pair of retainer slide members is carried on the innermost two doors, respectively, for engagement with the rear surface of the apron.  The advantage of the present con-struction over the devices of the prior art is that there is eliminated all binding between the slide members and the apron as the doors are opened or closed, thus providing an enclosure that is both easy to used and reliable in operation, even over extended periods of time.

Abstract: Case 780206 METHOD OF PREPARING SUBSTRATE SURFACE FOR     ELECTROLESS PLATING AND PRODUCTS     PRODUCED THEREBY                    Abstract of the Disclosure Polyalloy catalytic coating formulations are used for preparing a metallic substrate surface to enhance sub-sequent plating thereover of nickel, cobalt or polyalloys including nickel or cobalt.  At the same time, these cata-lytic formulations can be rinsed subsequent to their ap-plication onto the substrate and prior to the electroless deposition thereover.  Improved products such as printed wiring boards may be made with these catalytic formulations.  Such boards are prepared by depositing metal and forming circuitry patterns by using resists, etching techniques and the like which typically leave copper specks on the non-conductive board.  The invention discourages electroless deposition by a nickel-containing plating bath over embedded copper specks, thereby reducing the possibility of developing bridging within the circuitry and in general undesirably increasing the conductivity of the board at locations other than on the circuitry pattern to produce printed wiring boards that are extremely resistant to developing short circuiting problems.

Abstract: A TRACTOR DECELERATOR     ABSTRACT OF THE DISCLOSURE           A decelerator for a tractor which has a source of electric current and an engine.  The tractor incorporates a speed control to establish an idle speed for the engine, with the speed control being manually adjustable to establish a pre-selected speed for the engine which is higher than the idle speed.  The manual adjustments of the speed control to these higher speeds is achieved through the use of a selector that is connected to the speed control.  The tractor also utilizes a clutch connected to the engine, with a clutch control to selectively transmit power from the engine when the clutch is engaged and disengaged.  The decelerator incorporates a mechanism interposed between the selector and the speed control.  The mechanism is electrically connected to the source, and will maintain the engine at the idle speed during the engagement and disengagement of the clutch in response to electric current from the source.  The mecha-nism will also return the engine to the pre-selected speed, when the clutch engagement is completed, and the electric current ceases to flow to the mechanism.  The flow of electric current to the mechanism of the decelerator is controlled by a switch interposed in the electrical con-nection between the source and the mechanism.  The switch will respond to the clutch control by completing the con-nection before the clutch disengagement begins, and by breaking the connection after the clutch engagement is completed.
