Abstract: ABSTRACT OF THE DISCLOSURE       A ski safety device prevents unintentional cross-ing of skis during skiing.  It has a support plate mountable on an upper surface of a ski, and a frame above the support. A bottom wall of the frame faces the upper side of the support and a layer of elastically compressible material, such as plas-tic foam material, is interposed between them.  The bottom wall of the frame is formed with an elongated opening and the upper side of the bottom wall has at opposite sides of the opening re-spective depressions which extend outwardly away from the open-ing.  A projection extends upwardly from the support through the opening and is formed with two transverse extensions which enter into the respective depressions when the frame is turned rela-tive to the support from a position in which the elongation of the opening is parallel to that of the extensions to another position in which the two directions of elongation are inclined relative to one another, under simultaneous compression of the elastically compressible material.  Thus, the frame is readibly detachably secured to the support and thereby to the ski in which the support is mounted.

Abstract: PROCESS FOR PRODUCTION OF SYNTHESIS GAS              Kenneth M. Barclay James  R . Birk William E . Parkins Abstract of the Disclosure A process for the production of a synthesis gas, capable of being upgraded to a high BTU pipeline gas, by the partial oxidation and substantially complete gasification of a carbonaceous material under CO-promoting conditions wherein the carbonaceous material, oxygen, and recycled carbon dioxide from the process are introduced into a molten salt containing an alkali metal carbonate and a minor portion of an alkali metal sulfide, the system being operated at a selected temperature and pressure between 1400 and 2000°F and between 1 and 100 atmospheres.  The molar ratio of carbon dioxide to oxygen employed is controlled at from about 0.6:1 to about 1.2:1 to control the CO production and also to maintain the molten salt at a desired operating temperature. Sulfur and ash introduced with the fuel are retained in the molten salt.  The gaseous effluent, containing a molar ratio of carbon monoxide to carbon dioxide substantially greater than one, is reacted in a water gas shift reaction, followed by removal of the carbon dioxide present in the gaseous effluent from the shift reaction to produce the synthesis gas, capable of being reacted further under appropriate conditions to produce pipeline gas, methanol, ammonia, or gasoline. At least a portion of the removed carbon dioxide is recycled for admixture with the oxygen to form the feed gas to the molten salt containing the carbonaceous material.

Abstract: LIQUID AERATION DEVICE                Abstract of the Disclosure A liquid aeration device includes a head box having a bottom wall, a pair of spaced side walls interconnected with the bottom wall, and a pair of spaced transverse walls inter-connected with the side and bottom walls to form a receiver chamber into which liquid to be aerated is fed and from which such liquid passes through orifice means formed in one transverse wall of the head box from whence the liquid by free fall passes through an entry chamber and enters a vertically disposed downcomer conduit interconnected at its bottom with a pressure chamber to which a vertically disposed riser conduit is also connected.  A third transverse wall is interconnected with the side walls and spaced downstream somewhat from the transverse wall in which the orifice means is formed and since the head box is of the open top type, an excess of liquid which over-flows the transverse wall having the orifice means is allowed to overflow the third transverse wall and to fall by free fall downwardly through the space adjacent the upper end of the riser conduit.  If desired a second or more phases may be used and which would include the above described components.

Title: Sacrificial anode with partially perforated metal tube embedded in anode
Inventor: HOSSLE LUDWIG
IPC: C23F13/22

Granted: 1981-06-16
Abstract: Abstract Of the Disclosure Method, arrangement and sacrificial anodes for cathodic protection systems wherein inner portions of a tank or container, at least partially filled with a liquid, are exposed to a corro-sive inner environment and are protected against the corrosion by the provision of a consumable sacrificial anode, the material of which gradually migrates through the liquid to and is deposited on the inner tank portions, without an external voltage being applied, and wherein the inner tank environment also promotes detrition of the sacrificial anode. The invention provides the anode with an inner metal tube,  with openings in the tube wall, preferably by perforation, so that the anode material normally constitutes a bar-rier between the tube interior and the tank environment, and obtains an indication of progressive detrition or consumption of the anode, at which point the consumable anode should be replaced for contin-ued effective cathodic protection. A pressure difference is usually effected between the tank environment and the tube interior, either by pressurizing the tank, or by providing a source of pressure or vacuum in the system. Indication may be obtained in several ways, e.g. in an inspection chamber having a window that allows the level of the entrained liquid to be inspected, in that the chamber may have a pressure-responsive member therein, such as a membrane, or a float that can actuate electrical or other switch means. The in-vention describes additional, optional features of the method, ar-rangement and sacrificial anodes. In a preferred, exemplary form, the latter may have a small slidable plunger that can give visual, preferably color-coded information on the consumption of the anode.

Abstract: COARSE AND FINE ADJUSTMENT WARP COIL                     ABSTRACT    An inductor coil consisting of two cores enclosed by a single layer of wire is disclosed.  The cores may be of the same or different permeability.  The coils arranged in this configuration behave like two coils in series in which the relative values of inductance can be varied independently, thus the change in inductance depends only on the number of turns and the relative permeability of the cores.  Decreased sensitivity, however, is obtained because of the increased area inside of the coil provided by the two cores side by side.

Abstract: A B S T R A C T     In an electromagnetic driving device, such as a linear or rotary drive motor, the polarization of the poles of at least one of two relatively movable parts is controlled.  In order to provide a wide variability of speed and of performance range combined with a simple structure of the device, the electromagnetic poles of one part are simultaneously changeable in polarity.  The current input of each electromagnetic pole of the one part is controlled such that a polarity change to the same polarity as in a cooperating pole of constant polarity of the other part takes place at the very instant at which the cooperating pole comes to a position opposite to the pole to be changed.  A polarity change to a polarity opposite to the polarity of the cooperating poles of constant polarity of the other part takes place, in dependence of whether the succeeding poles of each pole group all have the same or alternately opposite polarity at each moment, at the very instant at which the pole of constant polarity which moves towards the electromagnetic pole to be changed is positioned at a distance from the pole to be changed,  The advance in the art is in that the motor of the present invention provides a wide range of speed and performance control combined with a simple structure and economical production of the motor.

Abstract: ABSTRACT OF THE DISCLOSURE A collapsible dome-shaped frame for a tent or similar structure includes a polygonal top ring formed of alternating fixed and pivotal sections, with a foldable, arcuate leg or pole  connected to each pivotal section.  In the collapsed condition of the frame, the poles extend downwardly, substantially at a right angle to the plane of the top ring forming a barrel-shaped cage for carrying a tent and groundsheet.  In order to open the frame, the poles and each pivotal section are rotated relative to the fixed sections of the top ring, so that the poles extend outwardly from the top ring in the same plane as such ring, and the pivotal sections are locked in the open position.  The poles, which are formed of arcuate segments interconnected by self-locking hinges, are unfolded to the open position, in which they define the dome-shaped frame with the top ring.
