Abstract: A cation exchange membrane of a fluorocarbon polymer containing pendant carboxylic acid and/or carboxylate groups, preferably having, at a predetermined ratio, pendant carboxylic acid and/or carboxylate groups and pendant sulfonic acid and/or sulfonate groups uniformly distributed therein, is produced by contacting with a reducing agent a fluorocarbon polymer containing pendant groups of the formula: -O(CF2)mSO2X wherein X is a fluorine atom, a chlorine atom, a hydrogen atom, M or OM in which M represents a hydrogen atom, a metal atom or an ammonium group, and m is as defined above, and transforming the resultant to a film. An excellent double-layer type composite cation exchange membrane can be produced by laminating the above-mentioned membrane having pendant carboxylic acid and/or carboxylate groups and pendant sulfonic acid and/or sulfonate groups on a membrane of a fluorocarbon polymer containing pendant sulfonic acid and/or sulfonate groups. In such a type of double-layer cation exchange membrane, both the two membranes are based on the same kind of polymer and, hence, peeling-off at the interface of the two layers can be well prevented while exhibiting high current efficiency and low electrolytic voltage.

Abstract: A method and apparatus for the crystallization of solids from liquids includes a vessel (8) having an elongate vertical spray chamber (10) which overlies and is in flow communication with a collection basin (22) for collecting slurry from the spray chamber. The collection basin has a cross-section larger than the cross-section of the spray chamber and preferably includes a side wall (24) which extends upwardly beyond the lower end (18) of the spray chamber (10) to define an opening between the wall of the basin and the spray chamber which communicates with the atmosphere. A blower (14) is located in the top of the spray chamber to draw air at substantially ambient atmospheric conditions through the opening between upper end of the basin and lower end of the spray chamber and upwardly through the chamber (10). The slurry solution which is to be concentrated and crystallized is sprayed into the chamber and directly contacts the air flowing through the chamber thereby resulting in evaporation and concentration of the sprayed slurry and and crystallization of solids therefrom. The slurry collected in the collection basin is recirculated and returned as a spray at the upper end of the chamber. If desired, the recirculated slurry may be heated prior to being returned as a spray at the upper end of the chamber and the heating may be achieved in a heat exchanger (36) so as to utilize waste heat in its operation; this may also be employed to condense the otherwise wasted vapour from a series of vacuum evaporators and further concentrate the product.

Abstract: The values of incorrect samples of, for example, a digital audio signal are estimated by means of interpolation. For this purpose an appropriate sampling interval is determined from the number of incorrect samples, in which interval the incorrect samples are situated. Subsequently, a best-fitting recursion formula is determined from the values of the samples, a first estimate being taken for the values of the incorrect samples. By means of this recursion formula the value of a sample is expressed as a weighted sum of the values of a number of preceding samples and an error term. By means of the recursion formula thus found the values of the incorrect samples are subsequently estimated, in such a manner that they are best-fitting values for the recursion formula. The Application also discloses a device for carrying out the method.

Abstract: A semi-automatic split needle bar sewing machine (10) includes a sewing machine (12) which is driven by a motor (26) that drives a left needle (22) and a right needle (23). A presser foot (24) is operated by presser lift actuator (30). The needles (22) and (23) can activate in unison or independently by use of fall out actuators (41) and (43), respectively. A control chassis (50) includes a microprocessor controller (51) that is programmable through an input panel (44). An edge detector (40) detects the edge of the material to provide feedback for the microprocessor controller (51). The microprocessor controller (51) is operable to sew a decorative pattern with mitered corners by sensing the pivot point of the mitered corner and automatically disengaging one of the needles (22) or (23). The microprocessor controller (51) then continues single needle sewing around the apex of the mitered corner by counting a predetermined number of stitches and varying the length of the stitches such that the needle is in the correct position when the single needle sewing again arrives at the pivot point on the other side of the mitered corner. In this manner, it is not necessary for the operator to manually adjust the length of the stitches around the apex of the mitered corner.

Abstract: The invention concerns a process for producing products of Al-base alloys essentially containing Li, Mg and Cu as main alloy elements and having a high level of ductility and isotropy. The process comprises subjecting the homogenized product to a "tepid" transformation operation at from 100 DEG  to 420 DEG  C. The intermediate annealing operations, if required, are carried out in the range of from 200 DEG  to 550 DEG  C. The rate of cooling after the intermediate annealing operations is generally kept at from 1500 DEG  C./second to 30 DEG  C./hour. The isotropy and ductility of the resulting products are considerably improved in comparison with the prior art processes.

Abstract: A passive integrated transponder (PIT) is attached to or embedded in an item to be identified. It is excited via an inductive coupling from an interrogator. The PIT responds to the interrogator via the inductive coupling with a signal constituting a stream of data unique to the identified item. The signal is in the form of two different frequencies, a shift from one frequency to the second during a bit cell representing a data "one", and a shift from the second frequency to the first frequency representing a data "zero". The responsive signal is then detected and processed for utilization in a data storage or display device.

The hangers permit upward removal motion and rotation of the inner conduit with respect to the drill pipe, but prevent downward motion. Individual inner conduit sections are joined together at lockable stab joints in which locking is accomplished by the rotatable engagement of a key and locking socket. Preferably, the inner conduit is manufactured in uniform lengths and mounted in drill pipe sections of non-uniform lengths by means of drill pipe adaptor subs. In addition, a removal tool can be used to remove the inner conduit from the drill pipe by engaging the hangers of the lowest inner conduit.
