Patent ZA-796090-B (ZA)
Title: Composite material for secondary container packaging
Inventor: PEER A
IPC: B65D71/14
Filed: 1979-11-13
Abstract: A secondary container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc., comprising a composite of a paper material laminated to a plastic film. The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other secondary packaging paper materials. The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional secondary container packaging material. Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite. The plastic film may be 0.25-2 mils thick and is preferably formed of polyethylene terpthalate, polyethylene, polyvinylchloride, polypropylene, or cellophane. The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film. Adhesives are used to bond the film to the paper and are selected to be compatible with the film used. The film may be metallized to produce a foil effect or may be strengthened by radiation treatment.

Title: Process for the selective hydrogenation of triglyceride oils with a metallic catalyst in the presence of a diamine
Inventor: KUIPER J
IPC: B01J31/28
Filed: 1980-06-16
Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.

Title: Apparatus for mixing batches of flowable solid materials
Inventor: MATHIS PAUL
IPC: B01F15/02
Filed: 1984-10-01
Abstract: Apparatus for mixing charges of flowable solid materials has a hollow cylindrical housing with two upright end walls and a hollow shell between the end walls. The lower part of the shell has a large material evacuating opening sealable by two mirror symmetrical doors which are pivotable about horizontal axes. The opening extends all the way between the end walls and is large enough to allow for gravitational outflow of the entire contents of the housing irrespective of the angle of repose of the charge. The doors are bounded by edge faces which make oblique angles with their external surfaces and abut against complementary edge faces of the end walls and shell. Sealing strips on the shell and end walls are engaged by deforming members at the external surfaces of the doors when the opening is closed. The abutting edge faces of the doors also make oblique angles with the respective external surfaces.

Title: Multiple temperature level regeneration of co2 from physical solvent
Inventor: RANKE GERHARD
IPC: B01D53/14
Filed: 1984-12-04
Abstract: To regenerate a physical solvent, loaded with sour gases, especially CO2 and H2S, the loaded solvent is treated with a stripping gas and/or is expanded to separate absorbed CO2 and the resultant solvent is subjected to thermal regeneration to desorb H2S. To reduce energy requirements during regeneration, the CO2 desorption is conducted on at least two different temperature levels, the second being for example 30 DEG -80 DEG  C. higher than the first, with the first being conducted, e.g., at about those low temperatures conventional to low temperature absorption systems.

Title: Process for the production of asymmetric hydantoins
Inventor: URBAN FRANK JOHN
IPC: C07D491/107
Filed: 1985-08-19
Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.

Granted: 2005-08-03
Abstract: A cheese substitute to imitate grated parmesan cheese comprises a protein or other bland edible particulate combined with a vegetable fat component and a salt along with flavouring to approximate the taste and smell of parmesan cheese. The preferred choice of protein or edible particulate source is a full fat pre-cooked soya flour. The vegetable fat chosen is one suitable to act as the binding as well as mixing matrix for the cheese substitute. Thus, a vegetable based fat such as partially or fully hydrogenated vegetable oil commonly known as "Vegetable Shortening" is used. Fine grain sodium chloride is preferred as the salt in order to allow ready and discrete combination with the other constituents of the cheese substitute.

Title: Ride control circuit for a work machine
Inventor: EVANS TERRY
IPC: B66F9/22
Filed: 2004-10-08
Granted: 2008-06-25
Abstract: A hydraulic circuit for raising and lowering a load arm on a work machine is adapted to provide a ride control function which will cushion shocks through the load arm as the machine traverses rough terrain. The circuit includes a hydraulic ram that moves the load arm and a first hydraulic accumulator connected to a first chamber of a hydraulic ram. The accumulator provides a cushioning effect to the ram when the ride control function is engaged. The accumulator is located between a first control valve and a load hold valve of the circuit so that the load hold valve will hold the ram in position should there be any sudden pressure drop in or adjacent the accumulator. The accumulator can also be connected to a control surface of the load hold valve to simultaneously open the valve and cushion the ram. A second dedicated accumulator can also be introduced for this purpose if desired.
