Abstract: METHOD AND APPARATUS FOR REMOVING     SKIN FROM ANIMAL CARCASSES                      ABSTRACT OF DISCLOSURE         An apparatus and method for removing the torso portion of the skin from the carcass of an animal, such as a hog, in-cludes an overhead support from which a carcass is suspended during the skin removing operation.  The skin is first removed from the hind quarters of the carcass and then a cut is made in the skin of the torso completely around the carcass just rear-wardly of the fore limbs.  A flap forming blade makes a longi-tudinal cut in the carcass and the longitudinal edge of the skin defined by the longitudinal cut is gripped by revolvable toothed cylinders carried by a revolvable drum to form a flap which is wound about the toothed cylinder.  A carcass engaging device holds the carcass against the drum during the flap forming operation.  A flexible pressurized movable blade positioned adjacent the drum progressively cuts the skin from the carcass as the drum is revolved.

Abstract: Abstract As an aid in counting servo tracks in a position servo system, a position window detector (30) which normally provides coarse and fine pulses to counting logic (53) also provides fine pulses to a reset switch (45) of a tachometer signal integrator means (33), resetting the integrator once for each track. In the event of position signal drop-out wherein coarse pulses are not properly generated, a threshold detection means (43) senses when the output of the integrator reaches a threshold level and produces a threshold reached signal which is transmitted to counting logic means (53) for incrementing a track counter (61).

Abstract: Abstract of the disclosure:              HOE 80/F 241 In ambient-air heat absorbers  composed  of many heat exchanger elements arranged one above another, the flowing air often flows too smoothly through the inter-mediate spaces, so that the heat exchange takes place only incompletely.     As a result of the insertion of lattice grids onto the (smooth) surface of the heat exchanger elements, this uniform flow is varied.     The result of this is a greater absorption of heat by the absorber.
