  • Patent number: 5074199
    Abstract: A deep fat fryer having an elongated housing for holding a bath of hot fat through which an endless main conveyor carries a food product through the bath from the infeed end to a discharge end of the housing. Above the main conveyor is a submerger conveyor having a run moving from the infeed end to the discharge end of the housing and adapted in operative position to line close to the food portions on the main conveyor and hold them submerged in the hot fat bath. In operative cooking position of the conveyor apparatus, the submerger conveyor nests into the side rails of the main conveyor and an elongated hood encloses the hot bath housing at a zone above the submerger covneyor from one end of the housing to the other.

  • Patent number: 5022045
    Abstract: The invention is directed to chemical compositions suitable for use in salt-solution transition temperature or hot mirror devices. It also provides methods of using these sensors (for the measurement of the humidity of gases) as well as the apparatus. The chemical composition which of itself senses the changes of water vapor pressure is birefringent at a first water vapor pressure and temperature, but non-birefringent at a second vapor pressure and temperature. The optical changes which accompany these phase changes may be amplified with polarizers. The means for heating the chemical composition can vary widely. Various thermometric devices can be used for temperature sensing. The accuracy required of the particular instrument model, the device's configuration, and the other components, selected for the particular system all affect the choice of thermometric device selected.

  • Patent number: 4976359
    Abstract: A rotatable merchandise display unit comprising a base with a support projecting generally vertically upwardly from the base, and supporting a vertically elongated column-like structure is rotatable relation thereon, with the column being formed of hinged sides and having a plurality of generally vertical rows of merchandise receiving trays disposed along the plural sides of the column, in laterally spaced relation with respect to one another. Each tray of such rows of trays provides upwardly opening pockets for receiving therein merchandise for display. Cams on the inner surfaces of the column sides coact with the central support and provide for the pivotal movement of the column sides relative to one another and thus the pivotal movement or undulation of the merchandise receiving trays with respect to one another during rotation of the column about the central support.

  • Patent number: 4975249
    Abstract: The invention provides novel chemical compositions for use in primary, optical/capacitance hygrometric devices. It also provides methods for using these compositions as sensors for the precise measurements of the humidity of gases as well as the apparatus. The chemical compositions, which of themselves sense the change in water vapor pressure, are birefringent, translucent, and anisotropic at a first water vapor pressure/temperature, but non-birefringent, optically clear, and isotropic at a second vapor pressure/temperature. Optical changes which accompany these phase changes may be amplified. Some compositions, exhibit abrupt and large increases in their dielectric constant coincident with the optical changes which occur at the phase shift point. Others show a large and precisely linear change in dielectric constant over many decades of relative humidity (RH), but the optical shift occurs at a precise point within the range.

  • Patent number: 4947712
    Abstract: A wrench-type socket for removing bolts and the like whose head has become damaged or otherwise worn, thus prohibiting its removal by the use of a conventional socket. The present socket has an internal central cavity which is formed with at least one, but preferably a plurality, of elongated projections or shoulders which extend into said cavity, and which upon rotating the socket are intended to partially penetrate into the damaged bolt head and thus provide a driving connection therebetween to thereby provide torque to said bolt to thus cause its removal. If desired, the user may strike the means for rotating the socket to embed the projections or shoulders into the bolt head.

  • Patent number: 4940040
    Abstract: An adjustable oven for mass cooking of food products comprising an essentially sealed enclosure having a conveyor received therethrough for conveying food through the oven. A heated gaseous cooking medium is applied to the food product during conveyance through the oven by impingement of the cooking medium at high velocity through spaced duct fingers disposed above and below the conveyor system. The gaseous cooking medium is heated and circulated through the oven at high velocity and subsequently recirculated for continuous cooking of food products in the oven. The cooking oven enables optimization of the cooking process by allowing at least certain of the duct fingers to be vertically adjustable relative to the food product so as to maximize heat transfer therefrom for any particular food product.

  • Patent number: 4913545
    Abstract: An adapter for a lens retaining ring and associated indirect ophthalmoscopy lens used by an examiner or practitioner during examination of a patient's eye fundus with a biomicroscope. The adapter includes a body portion for spacing the lens mounted in the retaining ring a predetermined distance from the eye of the patient when the adapter-retaining ring-lens combination is positioned against the eye of the patient under examination. The adapter is adapted to engage the eyelids of the eye under examination, and is so constructed so as to aid in maintaining such eyelids open, and openings are provided in the body of the adapter to aid in preventing fogging of the lens mounted in the lens retaining ring. The adapter may be selectively removable from the associated lens retaining ring (which may be a conventional or known lens retaining ring) or may be integrally formed with the retaining ring.
