Abstract: Apparatus and methods of using lasers are provided for spalling and drilling holes into rocks. A rock removal process is provided that utilizes a combination of laser-induced thermal stress and laser induced superheated steam explosions just below the surface of the laser/rock interaction to spall the rock into small fragments that can then be easily removed by a purging flow. Single laser beams of given irradiance spall rock and create holes having diameter and depth approximately equal to the beam spot size. A group of the single laser beams are steered in a controllable manner by an electro-optic laser beam switch to locations on the surface of the rock, creating multiple overlapping spalled holes thereby removing a layer of rock of a desired diameter. Drilling of a deep hole is achieved by spalling consecutive layers with an intermittent feed motion of the laser head perpendicular to the rock surface.

Abstract: Apparatus and methods of using lasers are provided for the perforation of oil and gas well casings and rock formations. A rock removal process called laser spallation is provided that utilizes a combination of laser-induced thermal stress and laser induced superheated steam explosions just below the surface of the laser/rock interaction to spall or fracture the rock into small fragments that can then be easily removed from the rock formation. The use of high power laser beams of kilowatt level is provided to rapidly cut the steel casings and perforate into the formation. Techniques of the invention increase permeability and reduce hole tapering while perforating a deep hole in reservoir rock formations.

Abstract: The portable box includes a housing forming four sides of an enclosure, with a front panel pivotally mounted to the enclosure and a support bar pivotally mounted in the upper end of the enclosure. The support bar includes an elongated strut and a clamping arm adjustably secured to the strut to selectively secure a display item in an upright position projecting upwardly from the support bar. The front panel is pivotally mounted on the enclosure to swing between an open position, wherein the support bar may pivot to store the display items within the enclosure, and a closed position securing the support bar in either an upright display position or an inverted storage position.

Abstract: A freezer includes an enclosed housing with cooling apparatus and a rotatable drive wheel mounted on one side wall within the housing. A plurality of support members are mounted on the drive wheel for rotation therewith. Food containers are selectively mounted to the support members to rotate with the drive wheel within the freezer housing. An operable door in the front panel of the housing provides access to the food containers, and a switch disengages the rotation of the drive wheel so as to permit dispensing of food product from a container.

Abstract: Apparatus in which a food product is cooked by being impaled on a plurality of heated grills that extend substantially therethrough. In this simplified apparatus, an operator rotates a first handle, which causes the elements of a separator to drop under gravity to a position among the grills and which further causes a press to descend to impale the food product onto the grills. The operator pulls and releases a second handle, which causes a container of heated cooking medium to raise and cook the food product, a cooking timer to start, the container to be lowered at the end of a predetermined cooking time, and the separator element to raise from the grills, thereby separating the food product from the grills. All of the above operations may be accomplished without the use of a motor or similar power source.

Abstract: Food products, for example, hamburger patties, are more rapidly cooked than with existing system and with reduced shrinkage. A cooking appliance is provided having a plurality of parallel spaced heat transfer fins. An array of projecting cooking grills on which the hamburger patty is impaled are thermally connected to said heat transfer fins. This composite cooking appliance is substantially immersed in a liquid heating medium so that heat is transferred through the fins and projecting grills to the interior of the hamburger patty. In this way cooking is accomplished in a relatively short period of time, and the amount of fat and meat juices that are melted or boiled away is reduced. A system for placing the hamburger patty on the cooking grills transports the patty to the cooking grills, then allows the patty to be impaled onto the grills.

Abstract: An improved apparatus for pressuring a hard frozen comestible, similar to hardened ice cream, while simultaneously subjecting it to mechanical action to reduce the crystal and cell structure of the material to transform it into a soft, smooth and creamy texture only slightly less cold than its starting temperature. The apparatus includes a hopper for receiving the hard frozen comestible to be treated, an auger positioned above the hopper and automatically actuated by movement of the hopper toward the auger to produce conditioning of the comestible by the auger as the hopper and auger move toward one another into an adjacent relationship. The hopper is supported on a saddle member, and vertical guide members are employed for supporting and guiding the saddle member during vertical movement thereof provided by linkage assembly.

Abstract: Hamburger patties are rapidly cooked with reduced shrinkage in a water base cooking liquid. A cooking appliance is provided having a plurality of parallel spaced heat transfer fins. An array of projecting cooking grills on which the hamburger patty is impaled are thermally connected to said heat transfer fins. This composite cooking appliance is introduced into a water base liquid heating medium so that heat is transferred through the fins and projecting grills to the interior of the hamburger patty. In this way cooking is accomplished in a relatively short period of time, and the amount of fat and meat juices that are melted or boiled away is reduced. An ejector is adapted to fit between the projecting cooking grills in order to remove the food patty after cooking is completed.

Abstract: Food products, for example, hamburger patties, are rapidly cooked with reduced weight losses. A cooking appliance is provided having a plurality of parallely spaced heat transfer fins from which project an array of cooking grills on which the hamburger patty is impaled. The appliance is adapted to be passed through a cooking environment so that heat is transferred through the fins and projecting grills to the interior of the hamburger patty. In this way cooking is accomplished in a relatively short period of time, and also the amount of fat and meat juices that are melted or broiled away is minimized. A device with a handle is provided for releasably engaging the cooking appliance so that the appliance can be conveniently moved even if hot. The device is provided with an ejection system for discharging the hamburger patty from the appliance.
