Granted: 1994-02-15
Abstract: ABSTRACT OF THE DISCLOSURE           An integrally moulded plastic device for storing containers filled with perishable beverages on a cooler shelf and for dispensing the containers inthe order received.  The device has a planar horizontal base which seats on a cooler shelf, a U-shaped sidewall extending upwardly from the base, and a central partition extending upwardly from the base within the sidewall.  The sidewall and partition define an inlet channel to one side of the partition and an outlet channel to an opposite side of the partition.  A curved portion of the sidewall spaced from the partition deflects containers pushed along the inlet channel into the outlet channel.  Inlet and outlet ports for receiving and delivering the containers are positioned side-by-side at a forward end of the device opposite the curved sidewall portion.  A pair of doors are integrally hinged to the sidewall and extend over the inlet to obstruct access to the inletchannel.  The doors can be deflected inwardly to push a fresh beverage containerinto the inlet channel and are returned by the intrinsic resilience of the plastic to their closed orientation.  The doors will not accommodate attempts to reach through the inlet and remove recently-introduced beverage containers.

Title: Method of constructing a heat exchanger and a heat exchanger constructed by using that method
Inventor: RAUNIO PENTTI
IPC: B23P15/26
Filed: 1988-12-13
Granted: 1993-01-12
Abstract: (57)  ABSTRACT            The invention concerns a method of constructing a heat exchanger as well as a heat exchanger cons-tructed  in  accordance  with  said  method.   The method comprises  piling of  essentially  similar corrugated  thermal  transmission  plates  (1)  to cover each other and connecting the, spaces bet-ween the plates  from their  edges  to inlet and outlet conduits (5,  6,   7,  8) for the mediums participating  in  thermal  transmission  so  that through every second space between the plates is passed a flow of heat giving medium and through every second space between the plates a flow of heat receiving medium.  Essential to the present invention is that the pressure losses of flows and the thermal transmission coefficient of the exchanger are established by piling the thermal transmission plates (1)  one over another so that the grooves  (11,   12)  in different  plates are placed at a selected angle with each other.  To make this possible the invention uses essentially circular  thermal  transmission  plates   (1)  or regular polygonal thermal transmission plates in which the direction of the grooves is such that the grooves in plates piled on top of each other may cross selectively at least in two different angles with each other.

Title: Apparatus for controlling precooking and machine peeling shrimp
Inventor: LAPEYRE GEORGE C
IPC: A22C29/02
Filed: 1989-05-26
Granted: 1996-10-29
Abstract: Apparatus for more efficiently pre-cooking and peeling cold water shrimp such as the species Pandalus Borealis is disclosed.   The apparatus includes a conveyor for moving the shell-on or unpeeled shrimp up and out of a feeder tank.   A perforated horizontal conveyor then carries the shrimp over a steam manifold with a multiplicity of apertures such that steam escapes from the manifold and rises through the perforated belt and surrounds the shrimp.  A cooking chamber which completely encloses the horizontal conveyor except at the bottom, contains the lighter-than-air steam such that the raw shell-on shrimp are at least partially cooked by the surrounding steam.  Since the lighter-than-air steam excludes all air from the cooking chamber, less oxidation of fats occurs and consequently a higher quality product is obtained.

Abstract: A revolving drum containing a multitude of oleophilic mechanical surfaces in fixed relationship with the inside drum walls is used to increase the particle size of bitumen phase in an aqueous mixture.  The mixture tumbles in the drum and the mechanical surfaces, passing through the mixture, capture bitumen phase particles that accumulate on these surfaces and increase in size until they are sloughed off these surfaces back into the mixture in the form of enlarged bitumen phase particles.  When the water phase of the mixture is relatively low in minerals content, the revolving drum and its mechanical surfaces are used to transfer water wetted mineral particles from the bitumen phase to the aqueous phase of the mixture, resulting in a bitumen phase with reduced minerals content.

Title: Electro-optical voltage measuring system incorporating a method and apparatus to derive the measured voltage waveform from two phase shifted electrical signals
Inventor: MILLER ROBERT C
IPC: G01R13/34
Filed: 1989-09-28
Granted: 1994-04-12
Abstract: Abstract of the Disclosure The  voltage  between  two  objects  is  measured utilizing an electro-optic crystal exhibiting birefringence in two axes (slow and fast) mutually orthoganal to an optic axis  extending  between  the  two objects.   Two collimated light beams polarized at an angle to the slow and fast axes is passed  through the crystal parallel to the optic axis with one of the collimated light beams retarded relative to the other by about 1/4 wave.   The two beams emerging from the crystal are passed through a polarizer and converted to phase shifted electrical signals by photo diodes in electric circuits which regulate the sources of the light beams to maintain the peak magnitudes of the two electric signals constant and equal.         As another feature of the invention, a stairstep output waveform representative of the measured waveform is generated  in  a  digital  computer  from  a  bidirectional cumulative  count  of  zero  crossings  of  the  two  electric signals which is incremented or decremented depending upon which of the two electrical signals is leading.   Improved accuracy of the output signal is achieved by adjusting the stairstep waveform by the magnitude of the smaller of the two electrical  signals, with the sense of the adjustment determined by the relative polarities of the two electrical signals.
