Abstract: A lactoprotein-free fat spread with a fat content of 20-60 % by weight, based on the total composition, of the water-in-oil type comprising a mixture of particles of vegetable fats being solid above 20°C and a liquid oil in such an amount that the total fat mixture contains at least 40 % of polyunsatured fatty acids. The water phase contains 0.1 to 5 % by weight of gelatin or agar-agar and 0.1 to 5 % by weight of solubilized starch, particularly an amylopectin rich starch. More particularly wheat or maize starch is used. The spread presents a pH of 4.3 to 4.8, preferably 4.6. The spread is prepared by subjecting a water-in-oil emulsion containing all fat and oil as well as all in water dissolved other substances to a first cooling to above 20°C with mechanical treatment, subjecting the mixture to a mechanical treatment without cooling thereby allowing a temperature rise of 2 to 8°C and thereafter continuing the cooling with mechanical treatment to below 20°C.

Abstract: An animal containment pen particularly for use as a maternity pen for calfing cows includes a front panel, two side panels, and a rear gate.  The front panel includes a head gate  section  adjacent  one  side  panel  and  a  squeeze  panel pivotally  mounted  on  the  front  panel  and  movable  from  a position alongside the front panel to a position squeezing the animal between the squeeze panel and the side panel adjacent the head gate.  A sliding gate is provided in the front panel between the squeeze panel and the opposite side.   The squeeze panel and the head gate are directly mounted in the plane of the front panel  so as to be formed therewith in an economic construction.   The squeeze panel  is mounted relative to the head  gate  so  that  movement  of  the  squeeze  panel  to  the squeezing position forces the head gate into a closed position to grasp the neck of the animal.  The side panel against which the squeeze panel cooperates includes basically a flat sheet a lower rear part of which can be opened to allow access to the rear   part  of   the  animal.

The apparatus includes a computer for comparing at least some of the electrical signals to each other and with established  criteria  to  determine  whether  the headlight is aimed within a prescribed degree of accuracy.   The apparatus describes the illumination pattern of a headlight by visually displaying at least some  of  the  electrical  signals  i.e.  the  light intensities and their locations, on a display.  The illumination pattern can be displayed as a series of isocandela lines, or can be displayed as a simulated headlight  illumination pattern on a road surface. Exemplary objects can be included on the road surface at selected intervals to indicate relative distances. The headlight illumination pattern can be compared to a properly aimed,  simulated headlight illumination pattern to indicate the necessary aiming correction. The apparatus further includes digital and graphic indications of the relative deviations between the headlight illumination pattern and a properly aimed headlight  illumination  pattern.     The  apparatus preferably includes an aiming probe for centering the headlight relative to the lens.

Title: Article stopping apparatus
Inventor: POULIQUEN ALAIN N
IPC: B65H29/66
Filed: 1991-09-26
Granted: 2002-12-03
Abstract: Apparatus for separating sequential batches of overlapping sheets includes a conveyor (4) of laterally spaced belts. Lift bars (13) secured to tubes are mounted for vertical positioning above the belts to raise the sheets from the conveyor and remove the moving force. The lift bars include spaced vacuum openings (12) coupled to the tube, which is coupled to a vacuum source. The openings are spaced for alignment with the trailing portions of sheets moving through the conveyor. A piston (15) in the tube selectively opens and closes the openings. The tubes are pivotally mounted at the downstream ends and the piston projects from the upstream end of the tube. A cam drive reciprocates the piston and simultaneously raises and lowers the tubes. The cam drive includes an inclined cam rod (40) on which a motor-driven rack (39) is slidably mounted. A link connects the rack to the outer end of the piston. The rack reciprocates on the cam rod and thereby pivots the vacuum tubes about the pivot unit and simultane-ously opens and closes the vacuum openings. The apparatus stops the leading sheets with successive sheets moving into increa-sing overlap. The leading end of a batch is stopped until the vacuum tubes and bars are lowered to place and release the sheets onto the conveyor belts in spaced relation to the preceding batch of sheets.  Wheels or other stop devices may be coupled to the top side of the sheets to assist the stopping action.

Granted: 2001-06-12
Abstract: An apparatus and process of steam treating carbon-aceous materials under a controlled temperature and pres-sure. The feed material is introduced into an autoclave or similar vessel and injected with steam at a high pressure and temperature for a controlled period of time to effect thermal restructuring of the carbonaceous material and to effect a conversion of the moisture and a portion of the volatile organic constituents therein to a gaseous phase.   Water, wax and tar are recovered during this process and the water may be used as a source of pre-heating feed ma-terial in another vessel while the tar may be used as a heat-ing source since it has a high heating value. The upgraded product is allowed to cool and then removed from tile reac-tion vessel. The invention alternatively contemplates use of a separate pre-heating chamber for the carbonaceous feed material.
