The resulting stock is then machined to the final shape of the product and polished to the desired surface texture.

Abstract: A brake mechanism for controlling the velocity of articles on a gravity conveyor has a pneumatically operated actuator. During each cycle of operation of the brake a charge of air of limited volume is supplied to the actuator. The actuator is equipped with an air bleed which limits the actuator's period of action during each cycle. The charge of air is supplied by an accumulator, which is normally connected to a source of compressed air. An article actuated sensor and connected valve, upon being tripped by an article, isolates the accumulator from its air supply and connects it to the actuator activating the actuator but limiting its air supply to the charge stored in the accumulator before the valve was shifted by the sensor. The charge, once exhausted, is not replenished until the sensor is released by the article.

Abstract: The specification discloses a conveyor facility including a continuously moving drive belt having upper and lower parts and a plurality of selectively rotatable control elements supported between the upper and lower drive belt parts. Each control element includes a peripheral configuration causing the elements to rotate in a transportation mode and remain stationary in an accumulation mode. Further included are vertically reciprocable pressure rollers for selectively lifting the lower part of the drive belt into engagement with stationary control elements to cause those elements to again rotate.

The plug is formed of a polymer and includes a bore selectively alignable with the through-passage to admit the passage of fluid. The plug valve is formed by forming the plug and attaching thereto a preformed polymeric shield by snap-fitting the shield onto the plug. The shield has an inner surface conforming to the periphery of the plug. The plug and shield assembly is positioned within a cavity of a mold. The cavity corresponds to the shape of the housing. A molten polymer is introduced into the cavity and intimately contacts the shield and forms the housing around the plug.

Abstract: An account is given of a method and apparatus for hardening mold parts, such as mold outer parts or mold cores for making metal castings, by using compressed air for forcing catalyst through the sand of the mold parts for reaction with a binding agent mixed with the sand.

Abstract: A press designed for producing true-to-size workpieces from powder material has upper and lower platens, a base plate, a die support plate and a lower stamp, which is moved hydraulically in translation in relation to the base plate and the die plate. The die plate and the base plate are parts of a frame structure using pull-rods and having the die plate and a lower joining plate as parts thereof. The frame structure is joined with the top platen of the press by way of a connection piece, which may be moved in translation in relation to the frame structure in the direction of pressing, whereas the lower platen of the press is joined up with the lower joining plate. To get an even density in the pressed workpieces and to make possible the use of modern electronic control systems the lower stamp of the press is made up of at least two lower stamp parts which are supported on machine parts.

Abstract: An accumulator conveyor is equipped with sensors which respond to article movement by pivoting about a vertical axis as the result of having a pair of laterally spaced wheels on opposite ends of a shaft with one wheel driven by the propelling member and the other by an article supporting roller. The first wheel is larger than the second wheel and is attached to the shaft while the second wheel is connected to the shaft by a one-way clutch. Pivotal movement of the sensor results from differentiation between the relative speeds of the wheels.

Abstract: The present invention relates to torches. The torch described herein has two components which together define a case containing battery means and a bulb, with a seal located between the two components. The torch is operated by causing relative movement between the two components.

Abstract: The cooling zone (24) for a kiln, more specially a roller kiln, made up of a preheating zone (21), a firing zone (22) and a cooling zone (24), through which the goods to be kilned (10), more specially ceramic tiles or plates are transported without any burning tools of refractory material supporting them, is (for the purpose of stopping any effect on the kilned goods in the cooling zone (24) and in the parts next to the cooling zone (24), because of the effect of the atmosphere in the cooling (24) and any reoxidation of the kilned goods (10) because of this, and for giving a simple way of producing effect on the outer face of the kilned goods (10) using a moving heat vehicle, more specially liquid heat vehicle) is indirectly cooled, and has inlet systems, able to undergo adjustment in their direction and their rate of inlet, for materials for producing an effect on the outer face of the kilned goods.

Abstract: A tool holder bracket is provided having a pair of parallel legs connected by a web which offsets the legs. One leg of the tool holder has a pair of anchor pins with enlarged heads for securing the bracket to a work support platform by inserting the anchor pins through keyhole-shaped openings and locking the bracket to the platform by engaging the heads under the platform. A pin is inserted through the other leg of the tool holder and an aligned opening in the platform to attach a tool to the bracket between the leg and the platform surface.

Abstract: In the mechanism for supplying waste metal cuttings from machine operations to a centrifuge having air suction means for separation and recovery of the cutting oils, a driven paddle-wheel type feed gate is provided in an inclined, gravity operated feed conduit for both maintaining a generally uniform rate of feed to the centrifuge and for serving as a barrier against the entry of air through the infeed end of the conduit. An air aspiration port is provided adjacent to and on the centrifuge side of the paddle wheel through which large metal chunks are discharged by gravity while smaller cuttings are entrained by the incoming air stream and transported past the port to the centrifuge. The bottom of the conduit at the feed gate is movably mounted to permit the passage of large, chunky material and means are provided to assure discharge of long pieces of material.

Abstract: A chuck for heavy duty applications has a plurality of radially slidable jaw mounts each actuated by an L-shaped lever mounted for rocking motion about a supporting trunnion. The levers each have a leg engaging one of the jaw mounts and another engaging an actuator. An external lubricant receiving port is provided adjacent each trunnion and a multiple conduit lubricant distribution system is provided extending through the supporting trunnion and actuating lever. The chuck body also has a lubricant flow channel through which lubricant flows circumferentially of the chuck to assure uniform distribution, eliminating lubricant concentrations and eccentric weight distribution in the chuck.

Abstract: The disclosed garment hanger has an elongated, molded plastic body with clamps at each end. Each clamp has a pair of spaced legs interconnected by an integral web between its ends which holds the legs substantially spaced from each other. The web has a relatively thin central section which functions as a hinge. The legs are biased into clamping position by a spring which is suspended in a pocket between the handle portions of the clamps. The lower end of the spring has a substantially circular head which becomes distorted in shape and presses against the bottom of the handle portions of the legs and against the web as the clamp is opening for effecting a change in the operating characteristic of the clamp.
