An apparatus for separating liquid and solid materials, especially for extracting juice from agricultural products, particularly from fruits, comprising a rotatably mounted press container subdivided by a substantially hood-like press or squeezing diaphragm into a pressure compartment and a press or squeezing compartment. The pressure compartment has an inlet arrangement for a pressurized fluid medium and the squeezing compartment has a juice outlet arrangement. The juice outlet arrangement possesses drainage channels at the solid-wall, preferably dome-shaped section of the container located opposite the squeezing diaphragm. The drainage channels are formed by substantially trough-shaped elements provided with perforations and arranged in spaced relationship from one another at the inside of the wall of the container.

Disclosed is an aeration device for aerating liquids having a foam-forming tendency. The amount of foam generated by such an aeration device is controlled by having the air inlet disposed at a predetermined foam level. The liquid inlet is disposed near the surface of the liquid to be aerated, such that solid particles floating thereon are taken into the aerator. Air and liquid are combined in the aeration device producing the desired foam. The foam level is prevented from exceeding the level of the air intake due to the fact that air is required to produce the foam, and if the foam level exceeded the air intake, it would be ingested into the pump reducing the amount of foam produced thereby. Particular embodiments disclose concentric foam and liquid intakes to a submersible aeration pump.

The present invention relates to an apparatus for the controlling of froth during the aeration of liquids. In the aeration (or treatment with gas) of sewage for the biological (or chemical) purification of the latter it is well known that considerable frothing occurs, which cannot be immediately controlled even with considerable effort and expense, for example using froth skimmers, froth barriers, oversize tanks, and the like. The problem is in providing an aeration apparatus which, without additional measures, that is to say by its own resources, is able to control frothing and thus keep it within permissible limits. The expressions 'aeration' and 'air' are here used to refer to any gaseous medium which is to be admixed with any liquid concerned in the present context. Similarly the expression 'air pipe' is to be understood as meaning a pipe for a gaseous medium. The following remarks therefore deal with a case of aeration not only for the sake of simplicity, but also because this is a frequent application of the apparatus described above. It is for the same reason that the aeration of sewage highly charged with organic substances, particularly from livestock establishments, will mainly be discussed.

An apparatus for the manufacture of a foamed molded article or part from pre-expanded polystyrene comprising a hollow mold compartment which communicates with a vapor chamber or compartment at least at the region of one of its walls by means of passageways or openings provided therein. Each passageway or opening is controlled by a valve arrangement responsive to the vapor temperature and which closes such passageway when the vapor temperature exceeds a temperature range contemplated for a limited foaming.

An injection moulding machine used in conjunction with a closed split mould, has its shot volume controlled by a device which responds to widening of the mould parting line occurring when the mould is completely filled with moulding material as a result of the pressure build up which occurs inside the mould. Contactless sensing of widening of the parting line is described, by means of electromagnetic sensing devices. The shot volume can thus be held at the optimum value at which minimum flash occurs and complete filling of the mould is assured.

A drainage system for fruit presses including a pressing cylinder and a pressure plate and back pressure plate assembly moveable toward each other. A flexible traction means including an elongate flexible core and a flexible perforated casing for allowing juice to pass therethrough while filtering same. The core having a substantially larger cross-sectional area at its central portion than at its ends. The core defining longitudinally extending channels throughout its length.

A method of regulating the hardening or setting time of a plastic mass in a mold of an injection molding machine, wherein during a relative movement between two mold halves in the presence of the pressure of the plastic mass the hardening time of the mass is regulated in the mold cavity as a function of the recuperation or recovery of such relative movement.
