Title: Cooled fresh milk storage awaiting tanker collection - precools each milking to avoid temp. fluctuations of stored, earlier milkings
IPC: A01J9/04
Filed: 1975-02-28
Abstract: Process and storing fresh milk. The milk is precooled in a reception chamber before being transferred to a storage tank where the desired temp. for storing the milk has been established. The total yield of a single milking, or of several, simultaneous milkings, is gathered into the reception chamber where it is cooled down to the desired storage temp. as quickly or as slowly as desired and then transferred into the storage tank. While milk is being precooled in the reception chamber, it is pref. subjected to constant agitation, but in the storage tank agitation is limited to a few times daily or to homogenising just prior to tanker collection. The process can be applied to existing plant using a pump to transfer from a reception tank to a larger storage tank. The pref. embodiment for a new installation superimposes the reception chamber on top of the storage tank in a single, insulated shell with cooling coils in the dividing wall between tank and reception chamber, from which transfer is by gravity. Used for storing fresh milk awaiting tanker. Collection may also be used for treating wine during prodn. and blood in abattoirs. Conditions remain ideal at all times in the storage tank since added milkings are always at storage temp. before introduction; this also means that the main stock does not have to be subjected to prolonged and harmful agitation each time a milking batch is introduced.

Title: Stripping device for cream cheese moulds - comprising piston with inflatable peripheral membrane
IPC: A01J25/12
Filed: 1975-07-09
Abstract: Stripping device comprises a piston with a peripheral packing (membrane) which can be inflated and applied against the wall of the plastic mould so that a perfect seal is obtd. in spite of any irregularities in the mould surface. The membrane, when deflated, leaves a certain amt. of play between the piston and the mould wall. Before filling the mould, the piston is placed in position; compressed air is admitted at nozzle in the hollow stem and expands into the space between the two pieces of the piston, which are held together by the bolts. The elastic membrane is clamped into position by the ring and seals the bottom of the mould. The latter is then filled. When the cheese is formed, the press. is relaxed and the piston pushed upwards. The cheese is extracted and remains on the upper face of the piston. Any defects in the mould surface are accommodated by the elasticity of the membrane on the piston, which is easily cleaned and can be made from stainless steel or high strength plastic.

Title: Mass transfer using semipermeable membrane - folded at connections, avoiding dead spaces and wrinkling, useful in artificial kidneys
Inventor: MARTINEZ FELIX JESUS
IPC: B01D63/10
Filed: 1976-07-29
Abstract: An appts. for mass transfer, incorporating a screen support and a flattened rectangular tubular membrane with its ends joined to inlet and outlet connections, has folds at the corners of the membrane. These folds take up enough of the length and the width of the flattened tubular membrane to avoid the formation of dead spaces within the membrane and allow continuous flow through the membrane and the connections. They are triangular in shape and have a ratio of length to width between 1.5/1 and 5/1, the long sides extending along the edges of the membrane. The appts. is used partic. in artificial kidneys, for purifying blood. The invention prevents the formation of dead spaces which can occur in existing appts. It reduces to a min. the formation of wrinkles in joining up to the connections.
