Abstract: A machine for extruding tamale filling having a small tank suitable for meat or bean filling and a larger tank specifically designed for masa dough. Each of the tanks are enclosed containers into which is fitted a floating piston above the ingredients. Air pressure is admitted to each tank through a pressure gauge regulator system to move the pistons down, extruding the ingredients of the tanks through a meat and masa conduit into an encasing nozzle. The work product of the machine is a meat or bean filler encased in masa dough which is wrapped in corn shucks or other suitable wrapping material to form the tamale.

Abstract: A large stainless steel tank having a conical bottom utilized for the mass cooking of corn to produce masa. Connected to the conical bottom of the tank is a multiplicity of steam rings interconnected by a manifold to an external source of steam. A conical screen is positioned closely adjacent the conical bottom to facilitate the injection of steam for heating the contents and selective injection of air for stirring the corn in the cooking or steeping process. Interspersed closely adjacent to the stream rings are air injection rings receiving compressed air from the surge tank connected to a compressor. Selective injection of compressed air sequentially from the inner air ring followed by injection through the intermediate air ring and the outer air ring stirs the liquid and corn content of the tank in the process of cooking or steeping.The steps of the method of the process of this invention include the cooking of corn, water, and calcium hydroxide mixture for predetermined period.

Abstract: A magnetic pin setter useful in constructing replicas of teeth for production of crowns and bridges. The device employs two support rods mounted on a base, each supporting a horizontal plate at its upper extremity. Mounted on the base between the two support rods is an adjustable work table. In producing castings for restoration work including crowns and bridges, dowel pins must be positioned for the casting and removal of individual tooth models to be restored. Small horseshoe magnets are magnetically attached to the horizontal plates and the second magnet interconnected to the first magnet holds a vertical support rod in position. The rods retain the dowel pins in position in the center of the individual teeth for the casting process.

Abstract: A cast fireplace comprising a heat exchanger as the rear wall component. The side walls, sloping top, and bottom plate are constructed of precast, refractory cement panels with the rear wall comprising a metal heat exchanger. Suitable ducting combined with a blower circulates air from the room through the heat exchanger and exhausts the heated air into the room to be heated. The efficiency of the fireplace is substantially enhanced by the combination extracting heat from the fire and projecting it into the room. The heat exchanger may be incorporated in the conventional brick fireplace; however, in the preferred embodiment precast, refractory cement slabs are utilized in the construction.

Abstract: A bailer pump designed for securing to a well head comprising an elongated stan pipe projecting upward from the well head supporting a motor driving a reel for cable through a drive train incorporating a magnetic brake, when the current to the motor is interrupted the magnetic brake is activated. A bailer is propelled into and out of the well in a repititious controlled manner. The electrical control mechanisms operate in conjunction with a pivot arm mounted at the top of the stan pipe on an axle. Pillow blocks retain the pivot arm in a tilting position. Tension or lack of tension on the cable passing over the top pulley causes a reciprocal tilting of the pivot arm and the pulley. The tilting arm contacts a micro switch which through time delay and relays start, stop, and reverse the electric motor operating the cable reel. The short delay in the well permits filling of the bailer and a long delay at the well head permits unloading of the bailer.

The device is designed primarily for utilization in conjunction with a closed circuit TV camera. The device is suitable for utilization with any camera means for recording the degree of movement of the deflection arm.

Abstract: An improved skateboard having a front platform separate and spaced from a rear platform. To each platform is attached a relatively conventional flexing wheel assembly with axle. In the first species of the invention the base plate of the wheel assemblies has resilient cushions mounted between the base plate of the wheel assemblies and the platforms. A torsion bar interconnects the base of the front wheel assemblies with the base of the rear wheel assemblies permitting rotary flexing between the two wheel assemblies. In the second species of the invention the torsion bar is connected to the pivotal collar of the shaft bushings rather than being connected directly to the base plates. To improve stability a support tubing is attached to the front and rear platforms and surround and encase the torsion bar. The support tubing maintains a front and rear platform in substantially constant spaced relationship.

Abstract: A unitary retainer for a cymbal on a stand. The combination employs a conventional stand for supporting a cymbal at the suitable height for playing by a drummer in a band. The essence of the invention is a one-piece retainer secured to the cymbal rod. The unit employs a threaded cymbal base with an integral drive nut; a sloping, flared shoulder; and the cymbal neck extending into flexible arms and a flared retaining head for passing through the hole in a cymbal and flaring to a fully extended dimension for retaining the cymbal on the stand.

Abstract: A fishing lure retriever for snagged fishing lures secured to a fishing line. The retriever consists of a cylindrical body supported around the line by line guides. A strong retrieving line is secured to the top end and hook snaring chains dangle from the bottom end. The device slides down a fishing line, engages and retrieves snagged fishing lures.

Abstract: A pumping device secured to a well head adapted to be counter balanced and operated by well head gas pressure. The pumping cylinder and the counter balance cylinder are positioned on a prolonged axis and employ a common polished piston rod operably mounted on the axis of the cylinders. The counter balance piston is pressurized through a volume tank receiving gas through a pressure regulator from the well head. The pumping piston is powered up and down by direct pressure from the well head gas. The flow of gas to and from the pumping cylinder is controlled by a floating piston five-way valve admitting directly well head gas to drive the piston and exhausting the gas to the gas flow delivery line. Snifter valves control the floating piston five-way valve and pressure regulators positioned between the well head and the gas flow delivery line maintain operable differential pressure in the system.
