Abstract: Duplicate thermoplastic plates are composed of a composition comprising a 1,2-polybutadiene having a crystallinity of about 10-30% and an intrinsic viscosity of greater than about 0.7. Matrices against which the duplicate thermoplastic plates are molded are formed of material containing said 1,2-PBD and a photoinitiator or a thermo-curable catalyst. The duplicate thermoplastic plates and matrices can give a high duration and reproducibility from an original pattern bearing design or image in relief, and they are molded with ease and in a great amount without difficulty. The use of the thermoplastic plates or matrices can provide a good releasability from the matrix against which the said plates are molded and from the original pattern against which the matrices are formed.

Abstract: The disclosure relates to an improved manual impact apparatus for driving a stake of the type having a head at one end thereof, which apparatus is characterized by a slidable sleeve having oppositely disposed and facing impact stops therein to confine the stake head therebetween during driving or pulling, whereby the stake may be longitudinally propelled in response to impact between one of the impact stops and the stake head.

Abstract: Parenterally administrable oil-in-water emulsions formed from nutritive oils, such as soybean and sunflower oils, are improved first by treating the nutritive oil with silicic acid to remove undesirable components such as peroxides, pigments, thermal and oxidative decomposition products, certain unsaponifiable matter such as sterols, and polymers. Purification is effected by treating the oil with silicic acid or silica gel either directly, or as a solution thereof in a suitable solvent, such as hexane. Autoxidation of the purified oil is prevented by adding to the purified oil a tocopherol antioxidant, .gamma.-tocopherol being preferred. There is also added a metal scavenging agent such as ascorbyl palmitate.

Abstract: The bottom securement device is utilized with a polygonal carton constructed from unitary blank of material and having a plurality of side panels and a bottom formed from a plurality of triangularly shaped bottom panels equal in number to the side panels with each bottom panel being hingedly connected to one of the side panels and inclining upwardly from the bottom edge of the side panel to which it is connected. A reinforcing rib is hingedly interconnected between abutting side edges of adjacent bottom panels and extends generally downwardly from the abutting edges of the adjacent bottom panels. The securement device can take one of several forms and is designed to engage the reinforcing ribs thereby to secure them in place and thereby secure the bottom panels in place. One securement device comprises an annular ring which is received in slots in the reinforcing ribs.

Abstract: A hog head is removed by suspending the carcass in a head-down position, marking the skin of the carcass around the neck, engaging a hook in the jaw of the carcass and applying force to the hook to rotate the head upwardly, and disengage the atlas joint whereby the head is substantially removed from the carcass. Continuous apparatus includes a head pulling structure running parallel to and synchronized with the carcass suspension system, and preferably horizontally offset therefrom, so that the carcass assumes a "bellydown" attitude when head-pulling force is applied thereto. Semi-continuous apparatus may apply the required force using a flywheel, a crank, a lever or a fluid cylinder.
