  • Patent number: 4080896
    Abstract: A method for the high speed application of printing code indicia. The articles to be imprinted are carried by a conveyor consecutively past an imprinting zone wherein printing heads on an imprinting wheel intercept the article at an imprinting location. The articles are spaced uniformly a predetermined distance, the lateral movement of the articles is restricted through the imprinting zone, a positive force is applied to the tops of the articles to immobilize the articles at the same time the imprint is applied and the speed of the circumferential rotation of the imprinting wheel is correlated with the speed of the conveyor and the number of printing heads carried by the imprinting wheel.

  • Patent number: 4078706
    Abstract: A molten metal metering and transfer device for use with a molding machine and a bath for holding and heating molten metal includes an elongate container which is supported in the bath with one end extending out of the bath and the other extending into the bath. An entry port is formed in the side of the container to allow molten metal to flow into the container and an exit port is formed in the container adjacent the top and above the bath. A uniquely formed plunger seated in the container moves downward into the bath, then upward out of the bath, trapping a predetermined amount of molten metal above its top surface. The formation of the plunger facilitates flow of the molten metal out of the container when the plunger reaches the exit port.

  • Patent number: 4077389
    Abstract: A pneumatic gasket adapted to be used in an oven door construction in which the door is adapted to be sealed to an oven surface when the door is closed. The gasket is an elongate extensile elastomeric member with first and second sections. The second section is a hollow member which is sealed at its ends or at other desired locations, the space between each of these sealed points forming a hollow air chamber of substantial volume which will expand when exposed to the temperatures produced by an operating oven. The second section may be sealed to produce the air chambers by adhesives such as a room temperature vulcanizing adhesive or by mechanical means. The second section may be a coextensive flap hingedly secured along one edge of the first section. The gaskets have means connected to the first sections removably to secure them to the oven surface to hold them in place between the oven and the door, while allowing them easily to be removed to replace them or to clean the oven.

  • Patent number: 4077337
    Abstract: Method and installation (apparatus) for continuous combustion of combustibles effecting combustion in a closed room into which a controlled quantity of substantially pure oxygen is introduced. The gases emitted by the combustible combined with oxygen to produce a semi-continuous explosion as a first effect; also produce as a side effect, an atomization of any water present (in the form of steam) and of any gaseous combustion products within the closed room as a second effect. Energy is provided not only in the form of calorific energy from combustion, but is released as radiation, and other forms produced by the atomization of the water and gaseous combustion products, including the kinetic energy of the gaseous molecules within the closed room.

  • Patent number: 4077083
    Abstract: A sponge mop retainer is attached to the end of a handle with a sponge member removably secured within the retainer. The retainer keeps the sponge member from rolling out when the mop is in use by tending to adhere to a surface while it allows the sponge member to be removed when the sponge member is worn out or dirty. The sponge member has four opposed longitudinal slits, one on each of four opposed surfaces. The retainer has a top wall and two side walls with the bottom edges of the two side walls having flanges which project inwardly, substantially toward one another. The free edges of each of the flanges have enlargements, substantially along their length, of a greater thickness than the thickness of the flanges which are engaged in two of the opposed slits to oppose movement of the sponge member away from the retainer.

  • Patent number: 4076406
    Abstract: A method of and apparatus for toning an exposed electrophotographic member in a camera or other electrostatic imaging device which uses liquid toner comprising toner particles suspended in a dispersant.The method contemplates running the liquid toner into a chamber containing the photoconductive surface of the electrophotographic member and a metal plate parallel with one another and spaced apart as two boundaries of the chamber. During the toning operation, a low d.c. bias is applied across the chamber between the photoconductive surface and the plate of a polarity opposite to that characterizing the latent image such as to repel toner particles from the photoconductive surface, but the voltage of the bias is low enough not to affect increments of the surface which have substantial charge on them. The result is that said increments with very little charge are left with practically no adhering particles.

  • Patent number: 4064751
    Abstract: The following specification describes a flowmeter in which a tube secured to a biased bellows for movement therewith receives a rod to define a passage having a small radial dimension relative the length of rod received in the tube. The passage provides a pressure drop, which varies linearly with flow rate and moves the bellows and tube to a position corresponding to the flow rate. An indicator rod extends from the tube through a wall of the meter housing to provide an indication of the bellows position and therefore the flow rate.

  • Patent number: 4063336
    Abstract: A clamp for heavy-duty use such as in clamping the telescoped tubing parts of exhaust systems of internal combustion engines. The clamp comprises a saddle portion including an arcuate pressure-applying edge adapted to engage the tubing and a conventional U-bolt that is adapted to engage the tubing diametrically opposite the pressure-applying edge of the saddle.The clamp saddle is made up of two very similar sheet metal members that are stamped in a suitable die or dies. Each member has a pair of spaced apart semicylindrical grooves formed therein, one along each opposite end of the member, there being an integral flange extending beyond each groove. One flange is wider than the other. Two of these sheet metal members are engaged face to face and the wider flanges bent over in reversed engagement upon the narrower flange of its opposite member. One of the engaged members has a tab integral with its upper edge that is also bent over into the upper edge of the other member in reversed engagement.
