Abstract: ABSTRACT OF THE DISCLOSURE     A substantially planar slab has two opposite edges castellated in such fashion that two such slabs may be inter-engaged with the slabs in the same plane with the castella-tions of one edge of one slab interfitting the castellations on the other edge of the other slab.  The sides of the castel-lations are inclined in a direction not normal to the plane of a major face of the slab.  Such slabs are useful for lining containers for molten  metal, and when forming such a lining all joint faces of the interengaging castellations not lying in vertical planes can be arranged to slope down-wardly away from the interior of the molten metal container. The thickness of the slabs, the angle of the castellations, the period of the castellations and the inclination of the slabs can be so chosen relative to the angle of repose of a loose fill of refractory material under the slabs that the loose fill particulate refractory material does not penetrate the joints between adjacent slabs.

Abstract: ABSTRACT OF THE DISCLOSURE           A phase angle balancing circuit for a variable speed constant frequency (VSCF) power system is disclosed. Multiphase electric power signals from cycloconverters are summed to produce continuously and automatically the zero sequence voltage of the multiphase electric power signals. The zero sequence voltage signal is provided to each of the modulator stages associated with the cycloconverters to effect phase angle correction of the phase relationships between the multiphase electric power signals.  A bandpass filter, having a passband center frequency centered on the preselected frequency of the multiphase electric power signals, is added to the phase angle balancing circuit of the present invention to make the zero sequence corrective means stable as a well damped negative feedback system.  The bandpass filter also eliminates undesirable frequency harmonics and "hash" on the signal having the zero sequence voltage caused by undesired frequency components in the multiphase electric power signal system.  In addition, another bandpass filter can be added having its frequency centered on the n harmonic (where n is the number of phases in the multiphase electric power system) for producing an n harmonic sequence voltage, which is also applied to each of the modulator stages.  This additional path reduces the n harmonic distortion in the power system voltage waveform.

Abstract: Abstract Multi-coloured detergent bars can be manufactured by extrud-ing detergent material through a multi-apertured plate in a detergent plodder and injecting a visually distinctive liquid at the plate.  The liquid is distributed throughout the detergent material in the form of striations as the material is compressed in the extrusion cone.   A specific form of external striping and the use of increased amounts of injected liquid can be achieved by having some of the apertures positioned peripherally on the plate.  These apertures form 'walls' of extruded materials which constrain the liquid into stripes.   The manufactured bar has a distinctive appearance because the external striations are wider than the internal striations.

Abstract: ABSTRACT OF THE DISCLOSURE     Cathodically electrodepositable resin having sufficient cationogenic sites to form, when enough of such sites are ionized, a stable aqueous dispersion, is dispersed in water with anionogen satisfying at least the requisite number of such sites for genera-ting such stable dispersion.  The anionogen is proportioned to supply as the satisfying anionic moieties C1-4 fatty acid anions and H2PO4 - anions in a ratio of about 0.25:1 to 5:1.  When such sites are from ionizable amino functionality, a mixture of car-boxylic acid (preferably acetic) and orthophosphoric acid is the anionogen, and such acids are proportioned so that their primary acid hydrogens are not substantially in excess of all the ionizable base functionality present.  The dispersion can be used for vari-ous coating purposes, but is particularly notable for its use in cathodic electrocoating of iron and steel cathodic substrates using iron and steel equipment without appreciable staining and discoloration of the applied coating, while also suppressing cor-rosion of containing and processing equipment.

Abstract: ABSTRACT OF THE DISCLOSURE            A process for producing ethanol from the reaction of methanol, hydrogen and carbon monoxide catalyzed by a phosphine-iodine promoted cobalt-ruthenium catalyst, the improvement of maintaining the phosphine to halide ratio and concentration within a critical range, and whereby the concentration of phosphine compound in the reaction mixture is increased without causing an undesirable decrease in the activity of the catalyst; thereby obtaining a highly stable and active catalyst providing an increased selectivity to ethanol formation.  This is accomplished under such conditions that the catalyst stability is maintained and the ratio of phosphine to halide is kept at a relatively constant value dur-ing the reaction.

Abstract: A B S T R A C T          IMPROVEMENTS IN AND RELATING TO TESTING COINS   A coin testing apparatus comprises transmitting and receiving coils on opposite sides of a coin passage-way.  The transmitting coil is connected to high and low frequency oscillators.  The output of the receiving coil is separated into the high and low frequency components by a high pass filter and a band pass filter.  In the high frequency channel the signal is amplitude controlled by a voltage controlled amplifier rectified by a rectifier and smoothed by a long time-constant circuit.  The initial rise in level caused by a coin entering between the coils is detected by an instantaneous level change comparator which responds to the rate of change of signal level at the output of the long time-constant circuit becoming equal to a preset threshold and causes a normally closed switch to be opened.  When the switch is closed a com-parator compares the signal with a reference value from a source and adjusts the gain of the amplifier until the signal corresponds to the reference value.  Upon the arrival of the coin the switch is opened and a long time-constant circuit causes the gain of the amplifier to be maintained at the level before the arrival of the coin.        A window comparator compares the difference in voltage with voltage ranges for acceptable coins.  A similar arrangement is provided in the low frequency channel but with two differences.  The switch in the low frequency channel is operated by the same instantaneous level comparator as is used for the high frequency channel and instead of a rectifier a novel sample and hold technique is used for providing a d.c. signal from the output of the amplifier.

Abstract: ABSTRACT OF THE DISCLOSURE            The method serves to control sluggishly reacting systems in which rapid changes in set value occur.  The controller (4) used has an integrating (I)-section (11) and a proportional (P)-section (20) separate from the I-section (11).  The I-section (11) receives a control variation formed from the actual value and the set value, whereas the P-section (20) is supplied with the set value.  The output signals of the I-section (11) and of the P-section (20) act on the plant (1).  The I-section (11) is blocked or interrupted for the duration of an abrupt change in the set value.  As a result of this relatively short interruption in operation of the I-section, the control provided by the plant is improved as compared with a method in which the change in set value acts on the I-section but with a delay determined by a delay element.

Abstract: METHOD AND COMPOSITION FOR REDUCING PAIN              ABSTRACT The present invention relates to a method and composition for reducing pain in animals, including humans, associated with gastro-intestinal dysfunction.  Gastrointestinal pain, and particularly ulcer pain, is poorly controlled by available uncontrolled drugs, not having undesirable side effects.  Dextromethorphan is known in the art as an antitussive, but has no known analgesic activity.  It has now been discovered that dextromethorphan provides temporary relief from gastric pain, and that the relief may be enhanced by combination with one or more of a histamine H2 receptor antagonist, an antacid, an anti-cholinergic, and an antiflatulent.
