  • Patent number: 4237580
    Abstract: The invention concerns a method and apparatus for severing the jowl muscles of a half pig's head, in order to facilitate subsequent boning of the half head to provide bone and pig's head meat as the end product.For this purpose, in one embodiment of the invention, the half pig's head (19) is placed on a moving conveyor (11) comprising a series of stainless steel plates (12), the half head being held securely in a predetermined position by a locating and supporting means (13 to 18) welded to the plate (12). The half head so held is presented by the conveyor to a fixed wedge member (20) pointing in the opposite direction to that of the conveyor movement, the wedge member acting to force the jaws of the half head progressively further apart to sever the jowl muscles.Preferably, the outer skin or rind of the half head is removed before the latter is placed on the conveyor.

  • Patent number: 4237582
    Abstract: The debris and pith removal from bagasse fiber is significantly enhanced by the flow of fiber from one depithing zone into a fiber washing zone and then to a second depithing zone without any intermediate settling of piling of the fiber. The fiber is maintained in a separated condition throughout the first depithing zone, the washer and the subsequent depithing zone. The result is a bagasse fiber having a greater quantity of the debris and pith removed with much less fiber damage.

  • Patent number: 4237601
    Abstract: Thick double heterostructure (Al,Ga)As wafers comprising layers of gallium arsenide and gallium aluminum arsenide on a metallized n-GaAs substrate are separated into individual devices for use as diode lasers. In contrast to prior art techniques employed with thinner wafers of mechanically cleaving the wafer in mutually orthogonal directions, the wafer is first separated into bars of diodes by a process which comprises (a) forming channels of substantially parallel sidewalls about 1 to 4 mils deep into the surface of the n-GaAs substrate (b) etching into the n-GaAs substrate with an anisotropic etchant to a depth sufficient to form V-grooves in the bottom of the channels and (c) mechanically cleaving into bars of diodes. The cleaving may be done by prior art techniques using a knife, razor blade or tweezer edge or by attaching the side of the wafer opposite to the V-grooves to a flexible adhesive tape and rolling the assembly in a manner such as over a tool of small radius.

  • Patent number: 4237606
    Abstract: In a method of manufacture of a multilayer ceramic board, a conductor land is formed and baked on a first substrate. A second substrate on which the wiring pattern is formed is then electrically connected to the first substrate via the land. An error in the substrate due to shrinkage at the time of sintering is thereby compensated by the conductor land. This assures the formation of a highly accurate wiring pattern on the sintered substrate surface, despite shrinkage of the ceramic during sintering of the raw sheets of ceramic.

  • Patent number: 4237613
    Abstract: Apparatus for measuring the wear of a shaft bearing includes a liquid, a source of fluid, a valve, sight gage and a transducer. The transducer has a probe which may be urged against the shaft by admitting fluid from the source to a chamber in the transducer. The liquid is in enclosed subsystem comprising the sight gage, an expandable chamber in the transducer and a connecting line. As the probe is urged against the shaft, the expandable chamber expands in a relationship to the movement of the probe. More liquid enters the expandable chamber, causing a corresponding decrease of liquid in the sight gage which is measurable. Upon completion, the fluid is vented, which allows the probe to return to a rest position.

Positioned intermediate the upper and lower fluidized zones are a plurality of tubular zones. Substantially parallel to the fluidized zones is a discharge leg positioned to receive fluidized solids from the lower fluidized zone in which the fluidized solids are fluidized in the leg at a level substantially equal to the level of fluidized solids in the upper zone whereby a portion of the solids can be removed from a repositionable discharge means in the discharge leg. The process involved in this invention utilizes a fluidized system for starch drying wherein the moisture content of the starch supplied to the fluidized bed is controlled to a level not exceeding 27% whereby the fluidized bed can be operated at higher temperatures without damaging the starch.

  • Patent number: 4237621
    Abstract: A damper structure for a clothes dryer vent is disclosed. The damper structure comprises a support member adapted to be inserted inside the dryer vent adjacent the inside wall of a house, and a damper plate mounted on the support member, so as to form a closed air space between the damper plate and the regular closure damper of the dryer vent for minimizing heat losses through the dryer vent. In order to fit a dryer vent of circular cross-section, the damper structure comprises a central damper element hinged at the top of the support structure and two lateral damper elements hinged one on each side of the central damper element for allowing full opening of the damper plate into the tubular dryer vent.

  • Patent number: 4237622
    Abstract: An industrial dryer particularly suited for small parts has a tub to contain the parts and a helical ramp along the interior tub wall. Vibratory motion makes the small parts move along the ramp. The tub has a double wall, the inside space between the walls defining an air plenum. The interior wall of the tub is formed with exit spaces through which the hot air emerges and blows over the parts as they move along the ramp. The plenum is continuously supplied with hot air to replace the losses. A unique method of forming the ramp from stair-step segments and partitions forms special conduits which focus hot air streams upon the parts as they move along the ramp in staircase fashion.

  • Patent number: 4237623
    Abstract: A food holding cabinet having a closed loop air circulating system to control both heat and humidity, the system including a blower having an air inlet at the front-top-center of the interior of the cabinet, the outlet of the blower being connected to an elongated heating tube the discharge end of which directs heated air over a water reservoir containing a plurality of upwardly projecting removable heat transfer plates. The quantity of moisture introduced into the flowing air is controlled by varying the number of heat transfer plates. The heated and humidified air flows downwardly through a duct at the rear of the cabinet, the duct having rows of perforations aligned with the undersides of product containing trays or baskets in the cabinet, the air being drawn through the cabinet for return to the blower inlet. Heat is controlled by a temperature controller having a probe mounted in the inlet to the blower.

  • Patent number: 4237625
    Abstract: A thrust producing shoe sole and heel having fluid-proof cavities respectively located in the heel portion and in the sole portion which underlies the metatarsal ball area of a foot for which the sole and heel is sized, the two cavities being connected by a restricted passageway. The material underlying the two cavities at the bottom of the sole and heel is resilient and wear-resistant. Fluid, either gas or liquid, is contained within the cavities and passageway in such pressure and amount as to cause bulges below the normal bottoms of the sole and heel, whereby at rest a foot on the sole and heel is cushioned comfortably on the fluid in the bulges, and in walking fluid under bulge producing pressure alternates through the passageway between the two cavities, producing shock absorption and an alternate lifting effect by the bulges which provides forward thrust both in the heel portion and the metatarsal ball area that facilitates walking.

  • Patent number: 4237626
    Abstract: Disclosed herein is a moldable foot wedge which when suitably treated as by heat, becomes deformable so that the person for whom the wedge is to be customed fit is allowed to stand on the wedge thereby deforming same to conform identically to the contour of the person's foot, thereby filling voids. An area below the rear heel on one side thereof is defined as a plug which is not subjected to the heat treatment so that a beneficial cant of inclination can be provided to the wedge by not allowing this cold plug to be heat treated and thereby deformed. A method associated with the article is similarily disclosed.
