Title: Apparatus and process for producing kettle-style chips
Inventor: HENSON WILLIAM D
IPC: A23L5/10
Filed: 1991-05-15
Abstract: Potato chips having hardbite texture and flavor characteristics of kettle-fried potato chips are produced in an apparatus comprising a fry kettle with cooking oil circulation and heat transfer means. Production efficiency is greatly increased over conventional batch preparation of kettle-style chips; batch size is significantly increased and total fry time is advantageously decreased.  In certain embodiments the batchwise preparation process includes the step of selecting texture-setting potato slice dehydration rate conditions for at least a segment of the frying time, which ends before the moisture content of the slices is reduced to about 45% by weight or less.  Selecting appropriate dehydration rate conditions enables the production of potato chips of a variety of textural characteristics over varying cooking oil time/temperature profiles.  After introducing a batch of potato slices into a kettle of frying oil, the potato slices are fried during the texture-setting time segment while controlling the frying to achieve the selected dehydration rate conditions.  After the texture-setting time segment, the moisture content of the slices is further reduced by continuing to fry the slices in the oil to achieve a moisture content in the slices of about 2% by weight or less.  Temperature may be controlled via a programmable control system.

Abstract: W. E. 55, 552 ABSTRACT OF THE DISCLOSURE       A structureborne vibration-compensated motor arrangement includes a pair of twin AC motors supported by a rotatable shaft structure and a stationary outer housing.   Each motor includes an annular stator core structure and an annular rotor field structure.   The stator core structure is mounted by an annular stator support  member  which,  in  turn,  is  stationarily supported  by  the  outer  housing.    The  rotor  field structure is mounted by an annular rotor support member in spaced relation,  either axially or radially,  from stator core structure.   The rotor support member, in turn, is mounted to the rotatable shaft structure for rotation therewith.   The twin AC motors are mounted with  the  stator  core  structures  located  adjacent opposite sides of the stator support member and the rotor field structures located adjacent the respective stator core structures opposite from the stator support member such that the twin AC motors are arranged back-to-back as mirror images of  one another for cancelling out axial and radial vibrations of the stator core and rotor  field  structures  at  respectively  the  outer housing  and shaft structure. Additionally, the respectively stator and  rotor support members are mounted by yieldably resilient members which isolate torsional vibration of the stator core and rotor field structures respectively from  the outer housing and shaft structure.

Title: Composite pillow featuring foam collapse preventing pad
IPC: A47G9/10
Filed: 1991-12-02
Abstract: Abstract A  pillow  comprises  a  foam  core  which  is  surrounded  by synthetic fibres.  The foam core, typically polyurethane foam, has the  same  basic  shape  as  the pillow.   The  synthetic  fibres, typically polyester, are layered having approximately the same thickness all around.  The hollow foam core has a smooth outside surface and a convoluted inside surface.  A thin rectangular piece of foam at the centre of the foam core cavity prevents the two convoluted    inside  surfaces  from  interlocking  when  pressed together.   The fibres and foam combination is typically held together and covered with a fabric pillow cover or ticking.  This pillow construction combines softness and comfort with support, durability and prolonged maintenance of pillow height using non-allergenic materials.

Abstract: ARC-GRAINED LITHOPLATE AND TWO-STEP METHOD FOR MAKING IT        ABSTRACT OF THE DISCLOSURE   An essentially flat "arc-grained" surface of a sheet of aluminum alloy is produced with a coarse and non-uniform microstructure which, after it is coated with a durable phosphate-free coating, provides excellent lithoplate. Though such arc-grained microstructure is much coarser than an electrochemically etched surface typically used on litho-plate, the very coarse surface is peculiarly well-adapted to provide durable lithoplate after it is coated with a phosphate-free protective surface. After the coated surface is coated with a photoresist the excellent resolution of prints is maintained over a large number of repeated uses in an off-set printing press. A method of producing lithoplate comprises, controlledly rastering an A-C, or D-C reverse polarity plasma-generating electric arc on an aluminum sheet less than 30 mils thick, kept distortion-free on a mounted surface such as on a cylindrical drum; then coating the arc-grained surface with a hard and durable, inert phosphate-free coating while maintaining a capillary microstructure in the surface adapted to provide a support for a photoresist for use in lithographic printing of adequate resolution.

Abstract: An improved fiber optic backlighting panel provides increased background illumination relative to the amount of light transmitted therethrough, in devices such as rubber keypads, membrane switches, liquid crystal displays, rigid panels or the like. The fiber optic panel comprises a light source and a layer of optical fibers arranged adjacent each other which transmit the light beamed therein to different locations throughout the device, to provide increased and uniform intensity of light at specific locations or uniformly distributed light throughout the device. The optical fibers are selectively terminated at the different locations by forming holes through the layer of optical fibers with a laser, according to a predetermined geometric pattern of dot locations stored in a computer memory. In one specific embodiment for application in liquid crystal displays, a layer of foam is used to diffuse and scatter light to provide uniform illumination.
