Abstract: SLIDING DOOR TOP GUIDE OR HANGER            ABSTRACT    An integral plastics body mounted on a corner connec-tor for a door can serve as either a hanger or guide. As a hanger, the assembly supports the weight of a door for sliding along a horizontal overhead track having a downwardly extending L-shaped limb.  If used as a guide with such a track, the plastics body can move vertically relative to the corner connector.   Rigid posts extend upwardly from the body for encompassing opposite sides of the foot of the L-shaped limb on the track.  A flexible finger extending upwardly from the body has a hook that fits over the top of the foot on the L-shaped limb for safely latching the plastics body to the track, thereby preventing toppling of the door.   A tab on the finger permits it to be manually flexed to withdraw the hook from over the foot and release the plastics body from the track.

Abstract: Molecular decoyants are chemical structures which func-tionally resemble an endogenous receptor. They may be used for the treatment of humans or other animals which have been subjected to a foreign agent which exerts an undesired effect only after first binding to that endogenous receptor. A decoyant is a frac-tion of an endogenous receptor which retains the essential ele-ments of the binding site of the receptor for the foreign agent or is a synthetic or biosynthetic derivative thereof. The .alpha.-184-200 amino acid sequence of Torpedo californica acetylcholine receptor is an example of a decoyant which protects against curarimimetic neurotoxins. Another example is the fraction of the CD4 receptor which retains the essential elements of the receptor for protec-tion against HIV.

Title: Fatigue life of a component such as a bar
Inventor: THUSE ERIK
IPC: C21D1/00
Filed: 1988-09-29
Granted: 1992-11-10
Abstract: ABSTRACT OF THE DISCLOSURE           The outer surface of an elongated metal component such as a bar is rapidly heated by an induction coil and is thereafter cooled by a quenching spray while being subjected to tensile forces so high that the center portion of the bar approaches yield causing the bar to elongate slightly.  The tension on the bar is released thereby obtaining high residual compressive surface stresses in the cooled outer layers of the bar which define an annulus and which shortens the bar slightly until compressive stresses in the surface layers equal the tensile stresses acting on the central sections of the bar thereby greatly improving the fatigue life of the bar.

Abstract: Pigs which are to be slaughtered at slaughterhouses are unloaded from the transport truck and driven into pens and stalled in these for some time, until they are driven out of the pens and over to a stunning  apparatus. The  pigs  of  a  supplied  lot  to  the slaughterhouse,  or part of the supplied lot,  are  treated as a separate unit during one or more of the above-mentioned stages of treatment, which means that pigs of a unit are constantly to be kept separated from pigs belonging to other units. Each unit may comprise e.g. 15 pigs.            The treatment of the animals in units reduces their aggressions, and their well-being is increased, which will result in a lower incidence of rind dagames, blood splashings and deviant meat quality of the carcasses.   A system for stalling of the pigs includes a number of oblong pens (1), which is placed next to each other. Each of the pens has an entrance gate (6), an exit gate (8) and a driving gate (10) which is movable in  the longitudinal direction of the pen.  Each pen is equipped with one or more stationary intermediate gates (4), which are placed at such a distance from each other, the entrance gate (6) and the exit gate (8), that the pen is divided into several rooms (3a,3b,3c). The size of each room corresponds preferably to the size of the unit of pigs which is to be treated.

Abstract: Abstract 1.   A multi-spindle automatic lathe. 2.1  Known multi-spindle automatic lathes are expensive because of their costly design, and their production output and production potential are restricted because of the limited number of work-piece spindles that are used.  The new, automatic lathe is intended to provide increased production output and more universal production potential from a simpler design. 2.2. The basic construction of an automatic lathe with eight tool spindles (10) for the production of work pieces in eight successive processing stations lies in the fact that in addition to the number of basic tool stations (1 to 8), each basic tool station except the first is once again provided as additional tool stations (2 to 8),which are arranged in the same processing sequence ahead of the basic tool stations (1 to 8), so that the total number of processing stations N = 2n-1, there being a loading and an unloading station at the tool station (1).  The work pieces are so processed that each work piece, after each process in a tool station, is moved linearly and at time intervals , relative to the next station, and after seven movement steps and a subsequent return movement, or a return movement between two movement steps, moves into its starting processing station.     2.3  The multi-spindle automatic lathe can be used for the mass production of various kinds of work pieces.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of detecting a noise disappearance of instruments,  etc.  in various instrumentations  in a chemical plant or the like and a detecting device therefor.   Detection values as being outputs from a detector (1) are input into a data store (3) via a data collector (2).   Input into a processor  (4) are a detection value as being a value (Sold) of the previous time from the data storer (3) and further a detection value as being a newest value (Snew) from the data collector (2).   In the processor (4), an absolute difference between the newest value (Snew) and the value of the previous time (Sold) is processed.  When this difference is smaller than a preset value, a count number (C) of a counter (5) is stepped up, whereas, when this difference is larger than the preset value, the count number (C) is cleared.  When an output signal from the counter (5) exceeds a predetermined threshold value, this case is regarded as occurrence of a noise disappearance, whereby a trigger signal (T) for actuating a notifier (7) is output from a limiter (6).

Granted: 1992-08-11
Abstract: Abstract of the Disclosure A tunnel lining process and an apparatus for use in the process in the prior art are improved in order to greatly enhance a lining speed and to facilitate the work of placing concrete for lining.  The improvements reside in that a pressing form for pressing a tunnel con-crete lining and a side form to be positioned on the side of the pressing form opposite to an already placed concrete lining are constructed as separate bodies in distinction from the prior art.  After the pressing form and the side form have been disposed along an excavated surface of a tunnel, lining concrete is placed in a space delimited by the both forms, the excavated surface and the already placed concrete lining so as to press the lining concrete onto the excavated surface to be lined.  Thereafter the pressing form is displaced along the side form and in parallel to the surface to be lined, and the steps of placing lining concrete and displacing the pressing form are repeated until placing of concrete over the entire length of the side form is completed.  Then the side form is displaced to the next lining region after the finally placed concrete has revealed its mechanical strength.          The aforementioned steps are repeated.  A tunnel lining apparatus favorably employed upon practicing the above-described process is also disclosed.
