Abstract: Closed cell phenol-aldehyde foam is prepared by a method which includes a novel frothing and curing technique. An admixture containing a liquid phenolaldehyde resole resin, a volatile blowing agent, and a surfactant is frothed to produce a stable froth containing closed cells. The cell walls are formed of the liquid resole resin and the closed cells are expanded by the blowing agent in gaseous phase. The froth is formed into an uncured shape and the liquid resole resin is cured to the solid state in the presence of an acid catalyst to produce cured closed cell foam. The internal temperature throughout the shape during curing is above the boiling point of the blowing agent but less than 212 DEG  F., and is sufficiently low to prevent further expansion of the shape in an amount to rupture the closed cell walls and thereby form an open cell structure. The liquid resole resin has a sufficiently low exothermic heat of reaction and the acid catalyst is present in an amount whereby the internal temperature of the shape during curing is less than 212 DEG  F. and within the aforesaid limits. The improved closed cell foam thus prepared is also provided.

Abstract: Novel process for removing polymer from aqueous absorbent solutions used to contact organic gas-containing gas streams comprising the steps of adjusting the polymer-containing aqueous absorbent solutions to a pH of not more than about 8.5, preferably not more than about 7.5, for example, about 6.0 to about 8.5, preferably about 7.0 to about 7.5, and removing the polymer from the resulting solutions by decantation and/or filtration. The novel process is particularly applicable to the system of removing acid gas from hydrocarbon-containing feed gases which contain one or more polymerizable components wherein the feed gas is contacted with an aqueous absorbent solution which absorbs the acid gas and, thereafter, the absorbent solution is stripped to rid it of said acid gas. The adjustment of pH can be accomplished by increasing the acid gas loading in the aqueous absorbent or by adding on acid, preferably one which will not form a heat stable salt with the absorbent. The pH adjustment, e.g., acidification, and filtration can be performed on the total mainstream or a portion thereof, i.e., a sidestream, before it is stripped.

Abstract: The printed products (6) are delivered by an individual conveyor (1) having a plurality of releasable grippers (2) arranged at a distance and one behind the other in the conveying direction (A). In order to release in each case a given number of, for example six, successive grippers (2), a release device (9) with a release rail (10) is provided which can be moved from a neutral position into a release position in which it effects an opening of the grippers (2) which are located in their active region. The printed products (6) thereby released fall onto a conveyor belt (14) which is arranged below and has the same conveying direction (B) as the individual conveyor (1), however a lower conveying rate than the latter. The periodic operation of the release device (9) now takes place in such a manner that the first printed product (6b) of each released section comes to lie on the last printed product (6a) of the previously released section in such a manner that the distance between these two printed products (6a, 6b) is the same as the distance between adjacent printed products (6) within the section. In this manner, an overlapping stream (S') is formed on the conveyor belt (14) in which the overlap distance is the same as the overlap distance within the overlapping stream (S) conveyed by the individual conveyor (1) and the conveying rate of the overlapping stream (S) is less than that of the overlapping stream (S'). <IMAGE>

Abstract: A method is described for sequential replacement of the lining in a rotating mill according to wear of the lining. Generally, such a lining consists of adjacent zones parallel to the rotational axis of the mill, the height of these zones varying periodically in the peripheral direction of the mill. According to the invention rubber beams of equal width are used, and for the replacement operation completely fresh beams of only one height are employed, this height representing the highest one of only a few preselected categories of beams. Upon removal of worn beams, these are reassorted according to the selected categories and those beams worn-out and unfit for even the lowest category are discarded. Thus, the reassorted beams not rejected can be reused properly positioned so as to maintain a suitable variation of the beam height in the peripheral direction of the mill, and only one height of fresh beams need to be held in stock. When replacing, the particular beam category may be retained at a certain beam position, or completely fresh beams may be inserted at positions of beams completely discarded, whereby the desired variation of beam height in the peripheral direction is obtained by suitable replacement or rearrangement of the remaining beams.

Abstract: A frequency dependent circuit is located in the main signal path of a dual path compressor or expander in which the main signal path is linear with respect to dynamic range and a further path provides a signal which boosts or bucks the main path by way of a combining circuit, but which is so limited that in the upper part of the input dynamic range the further path signal is smaller than the main path signal. The frequency dependent circuit in the compressor is called an antisaturation network with a characteristic FAS such as to effect a reduction in frequency response in the frequency band affected by overload in a transmission channel fed by the compressor, typically the upper end of the overall frequency band. The expander which is fed by the channel has a complementary antisaturation circuit with a characteristic F'AS providing a complementary increase in frequency response. The arrangement provides level dependent equalization without significantly affecting the noise reduction effect of a compressor/expander system because in dual path compressors and expanders the output of the circuits at very low signal levels is provided mostly by the further path. Thus, at high levels, where channel overload is a problem, the frequency dependent circuit is effective, while at low levels, where it is not desired or needed, the equalization effect is reduced. <IMAGE>

Abstract: An arrangement is disclosed for controlling a pneumatic motor 1, which, for example drives a hoist or lift. The arrangement allows the speed of the motor to be controlled, at a desired valve below the nominal speed. The arrangement includes a motor actuating valve 2 connected between the motor 1 and lines 17 and 3 respectively connected with a compressed air source N and, via a spool controller 4, with an exhaust line 26. The spool of the spool controller 4 has control surfaces 8, 13, 14, 21 so adapted to one another that adjustment of the motor actuating valve 2 causes the pressure difference upstream and downstream of said valve 2 to act via a two-way valve 10 on the spool controller 4 in proportion to the load on the motor 1 so as to throttle to a corresponding extent the exhaust flow from the motor. The motor 1 may have two directions of flow and the load may be effectively applied in both directions. A speed controller R is provided and may act to sense one of the pressures acting on the spool, as shown, when a set speed is reached or the inlet fluid, Figs. 2 & 3, not shown. The spool may be constructed as a differential piston (4', Figs. 2 & 3 not shown). <IMAGE>

Abstract: A process for the production of cast iron containing spheroidal graphite is disclosed. In the process, the iron melt, which contains sulphur, is treated with metallic magnesium, forming unstable MgS as a by-product. By the addition of CaSi, the sulphur contained in the MgS present in the slag is converted into stable CaS. As a result, the free sulphur which is released upon decomposition of MgS when the melt is allowed to stand for a fairly long time is prevented from going back again into the melt, reacting there with the dissolved magnesium, and forming MgS once again. Through the stabilization of the sulphur in the form of CaS in the slag itself, resulphurization is effectively prevented. The slag can remain on the melt surface for a longer time than hitherto. The slag provides a heat-insulating effect, so that even longer standing times which are possibly required in certain production processes, can be utilized.
