Title: Breaking foams by contact with surface - with low critical surface tension of wetting, esp. for high density foams
Inventor: HERMANT MARC
IPC: B01D19/02
Filed: 1976-01-20
Abstract: Foams are broken by contact with a lining or surface with a critical surface tension of wetting 12 dynes/cm. Used for foams produced undesirably in the chemical, textile, paper and food industries, or those produced intentionally e.g. foams used to lighten drilling muds in oil wells. Foams of high density (0.1-0.2) produced from solns. with low surface tension can be broken. Such solns. are those giving stable drilling foams with surface tension up to 24 dynes/cm at 25 degrees C, or aq. solns. of functional fluoro-derivs. with surface tension 15-16 dynes/cm at 25 degrees C.

Title: Machine using weight as source of energy - has oscillating masses mounted on rotating frame
IPC: F03G7/10
Filed: 1976-01-22
Abstract: The machine for utilising weight as a source of energy has pairs of weights (B) mounted on shafts with a common axis (A). The shafts are connected by a bevel gear train so that each individual weight rotates in the opposite direction to its companion. The pairs of weights are mounted at the corners of a parallelogram formed from pivoted links. The parallelogram rotates about the shaft (C) and as it rotates the descending pairs of weights exert a greater force than the ascending pairs of weights. In this way, it is claimed that a continuous source of energy is made available.

Title: Multiway valve distributor for water treatment plant - programmed to isolate process water lines from regenerant
IPC: B01J49/00
Filed: 1976-07-07
Abstract: Installation for treating water by passing it through a bed material which requires periodic regeneration, e.g. a water softener using a resin bed requiring brine regeneration, has a multiway distributor fitted on top of a bottle contg. the treatment bed. The distributed comprises three piston valvel which are normally held open by through flowing water being treated. One of the piston valves is on the inelt for outer treated water, A second is on the outlet for treated water and third is on a limited flow bypass which allows a proportion of untreated water to flow directly into the treated water outlet. A programmer is used to direct a pressurized supply of water simultaneously to the actuating pistons of all three valves which are thus closed. This isolates the treatment bed completely from the processed water systems while regeneration takes place via. inlets and outlet passages through the distributor. The equipment is simple, inexpensive and automatic. During regeneration, there is complete isolation of the treatment bed from the water circuit. There is no danger of contamination of process water or loss or regenerant.

Patent FR-2358779-A1 (FR)
IPC: H02M7/525
Filed: 1977-07-13
Abstract: In inverse rectifiers with no off-state voltage, there is the problem of rapid acquisition and evaluation of measuring signals, which correspond to the commutation current (ILK), and are intended to make it possible to regulate the commutation current, taking into account different amounts of disturbance. The aim of this is to stabilise the commutation. For this reason, an auxiliary coil (2) is provided, to which the commutation current (ILK) is applied, and which supplies a voltage (UR3) which corresponds to one of the temporary derivatives of the commutation current, as a measuring signal. For the evaluation of the positive and negative semi-oscillations of this voltage, one channel (3, 5 or 4, 7) with one integrator (5 or 7) is provided in each case, and it supplies a positive or negative actual value signal for the amplitude (IKist) of the commutation current, and can then be set to zero via an auxiliary input. A following sum point (8 or 12), as a target value -actual value comparator, receives a suitable commutation current amplitude target value (IKsoll), which is derived e.g. from an intermediate circuit voltage, and supplies a target value -actual value difference for a following commutation current regulator (9 or 13).
