Abstract: "A keeper part for positioning an inner layer of a two-layer cover on the outer face of a printing press cylinder"     ABSTRACT       On using two-layer covers on the outer faces of prin-ting press cylinders, certain  trouble conditions may he expected, more specially when the two-layers are fixed in position by different systems. Such trouble conditions are more likely in the case of the inner cover layer.        Such troubles are in connection with keeping the parts in their in register positions while on the other hand it 19 hard to see that there is enough space for the keeper part for the inner layer.        As may be seen from figures 2 and 3, these shortcomings may be taken care of in the present invention inasfar as the keeper part (5) for the inner layer (6) is in the form of a keeper rail (8) stretching along the length of the press cylinder and having a generally round cross-section, the rail (8) so resting against, and being supported by, the press cylinder at one end and at two positions (22, 3, 7) parallel to the axis of the press cylinder (1), that the keeper part (5) 18 regularly positioned and trued up in-re-gister in the round-the-cylinder and side-to-side directions and furthermore fixing pins (11) are joined up to the keeper rail along the length thereof with a registerwise spacing and distribution, said pins having heads (17) with such a form that, by turning the pins through 90° about their axis, the inner layer (6) may be locked onto the keeper rail (8).

Abstract: COLLECTOR FOR RADIATION-GENERATED CURRENT   CARRIERS IN A SEMICONDUCTOR STRUCTURE            Abstract An n+ type buried grid layer at the interface of a p+ type semiconductor substrate and a p type epitaxial layer serves to absorb alpha particle induced charge and other stray charge in the epitaxial layer and substrate. The grid layer is spaced sufficiently from a major surface of the epitaxial layer so as not to have any significant adverse affect on circuits and/or devices fabricated on the major surface.  Circuits and/or devices fabricated on the major surface of the epitaxial layer are thus at least partly protected against loss of information due to alpha particle hits and other stray leakage generators.  When no epitaxial layer is used, the buried grid is formed below the major surface of the substrate into which circuits and/or device are fabricated.

Abstract: A B S T R A C T                      SAFETY CLOSURE      A safety closure for containers comprises an assembled combination of an inner cap (103) housed in and surrounded by an outer cap (102). The inner cap (103) is provided along its outer circumferential surface or skirt portion (104) with a series of first teeth (106), the inner depend-ing skirt portion of the outer cap (102) is provided with a series of second teeth (107) which can be brought in engagement with the first said teeth (106) by means of a relative coaxial movement of the inner and outer caps. The safety closure can be unscrewed from the container or screwed upon the mouth of the container respectively only by exerting upon the outer cap (102) a downward pressure causing the said teeth (106 and 107) to become interengaged, whereafter the inner cap (103) can be turned. The downward pressure upon the outer cap is resiliently resisted by means of spring elements or lips (118) depending from the upper wall portion (113) of the outer cap (102) which lips (118) are flexing against a wall portion (110) of the inner cap (103) which is located inside the container mouth and which converges annularly. The inner cap (103) is pro-vided with a central cylindrical portion (111) rising up from said annu-lus (114), said lips (118) being operable in the space between the said cylindrical portion (111) and the inner mouth portion of the inner cap. Said central upper surface (112) of the inner cap (103) being rigidly and integrally connected to the remaining inner cap portion (110) in such a manner as to resist weight loads placed upon the safety closure even if the outer cap surface (113), surrounding the said central portion (112) may be slightly depressed thereby.

Abstract: METHOD AND APPARATUS FOR MEASURING THE SURFACE    TRANSFER IMPEDANCE OF A PIECE OF SHIELDED CABLE                          ABSTRACT A method for measuring surface transfer impedance of shielded cable within a frequency range below about 1 GHz is implemented with a single test fixture.  The test fixture provides a conductive cylindrical chamber which opens for installation of a sample of shielded cable.  The ends of the chamber are blocked by ferrite toroids to prevent radiation of high frequency electromagnetic energy.  One end of the cylindrical chamber may be externally short-circuited to the cable shielding for low frequency measurements. current source connects between the sample shielding and the conductive chamber boundary at the other end of the chamber.  Current flow at low frequencies is limited to the region between the current source and the short circuit.  Current flow at high frequency is limited to the region between the toroids.  The cable shielding and the fixture body beyond the toroids are short-circuited for high-frequency tests and open-circuited for low frequency tests.  The induced voltage in the cable is measured through feed-throughs provided in the test fixture.  The current source uses an isolation transformer to avoid ground loops in the low-frequency range.

Abstract: Abstract of the Invention Peats, mucks, soils, anaerobic sludges, lignites and other humus materials containing humic substances are slurried in the natural wet state with additional water at low pH to free humic acid from salts it may have formed in the natural state and to disperse the humic acid as a fine suspension in the water.  The resulting slurry is then screened to remove coarse material such as stones, fibers and cellulosic materials that may be present, and the liquid phase comprising a dispersion of humic acid is settled or otherwise treated to remove heavy inorganic fines if present.  The dispersion is then filtered to yield a relatively pure and dry filter cake, comprising crude humic acid.  This product may be converted to soluble humate salts by adding a solublizing agent such as sodium hydroxide, separating residual insolubles and drying the concentrated solution.  In the alternative, the solution before drying may be converted to relatively pure humic acid by acidifying the solution, separating and drying the insoluble humic acid.  The same solution may be converted to humates of limited solubility by reaction with suitable metal salts, and again separating and drying the product.
