Title: Method and apparatus for controlling the flying height of the head in a magnetic storage unit
Inventor: POHL WOLFGANG D
IPC: G11B5/60
Filed: 1986-09-24
Granted: 1991-10-01
Abstract: A B S T R A C T       Method and Apparatus for Controlling the Flying Height of the Head in a Magnetic Storage Unit The method  involves  the  steps  of  lowering  the magnetic head (8) to within aerodynamic distance from the surface  (16)  of  a  moving  recording  medium,  enforced further lowering of the head (8) until a tunnel current occurs across the gap between head (8) and surface (16), and maintaining said tunnel current constant by using the deviations of  the  current  from a predetermined value (which corresponds to a certain flying height).    The  apparatus  comprises  a  tunnel  electrode  (9) forming an integral part of the head assembly which is attached to a distance control mechanism (5) permitting the positioning of the head assembly with a one-nanometer accuracy. The tunnel electrode  (9) has a very slightly beveled shoulder  (45,  47)  ensuring early detection of asperities  approaching  the  head while  sitting on  the surface  (16) of the moving recording medium (3). Grada-tion of the potential between tunnel electrode  (9)  and surface  (16)  of the  recording medium  (3)  is used to enhance the response to asperities.

Title: Portable container, method for its production and device for accomplishing the method
Inventor: PATRIKSSON STIG
IPC: B31B50/86
Filed: 1986-10-03
Granted: 1992-03-10
Abstract: ABSTRACT A portable container is provided consisting of an encas-ing member arranged so as to form a space in which objects can be carried and a handle member,  consisting of at least one handle loop of string or similar material, which is attached to the encasing member.  Attachment of the handle loop is accom-plished in part by inserting at least one section of the string or similar material between two material layers of the encasing member, which are joined together by means of adhesive, whereby a channel is created between the layers of material through which said section of the handle member extends and in part by the nonuniformity in cross sectional shape over the length of said string or similar material when positioned in said channel in the completed package and by giving the channel such a form, that its shape and dimensions at least to a certain extent follow said nonuniformity in the string. The handle member is thereby secured to the encasing member even when the handle member is pulled in the longitudinal direction of the channel.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for the production of dialkali metal phosphates by ion exchange is disclosed.  The process is carried out by first ammoniatinq a water-soluble phosphate source such as phosphoric acid or monocalcium phosphate.  The resulting ammoniated phosphate solution is then contacted with a weak cation exchange resin in the alkali metal form to produce the dialkali metal phosphate as well as an ammonium-loaded weak cation exchange resin.  The cation exchange resin is regenerated by contacting it with an alkali metal salt solution which effects an exchange of alkali metal for ammonium to produce a regenerated weak cation exchange resin in the alkali metal form as well as a water-soluble ammonium salt corresponding to the initial alkali metal salt.  The process may be carried out in conventional fixed or pulsed bed ion exchange systems although it is most advantageously carried out in an Advanced Separation Device which is a multi-chambered device which enables the process to be carried out both continuously and with a greater degree of efficiency than is possible using conventional ion exchange systems.

Abstract: ABSTRACT OF THE DISCLOSURE       A film thickness measuring device  for measuring the thickness of a film formed on a sheet member conveyed with  the  rotation  of  a  rotary  shaft.    The  thickness measurement is accomplished based on averaged values for a period  of  time  which  is  determined  according  to  the rotation speed of the rotary shaft.  Consequently, errors due to the eccentricity or uneven surface of the rotary shaft are removed from the measurement values resulting in improving an accuracy of the thickness measurement of the film.

Title: Mobile radio transmision system
Inventor: SELBY GEOFFREY RICHARD
IPC: H04W88/02
Filed: 1987-09-16
Granted: 1990-11-20
Abstract: ABSTRACT                             RADIO SYSTEM A mobile radio transmission system comprises a plurality of base stations (BS) with corresponding service areas (SA) which together cover a geographical area through which mobile stations (M) can roam.  Each base station is connected to a central station (CS) by means of a respective two-way communication link (CL).  In order that it can be contacted without all the base stations having to put out a call, each mobile station registers in known manner with the base station in whose service area it is situated, and this is recorded by the control station.  When it roams into a new service area this process is repeated.  Houever, in order to preclude frequent re-registrations when the mobile station repeatedly crosses the boundary between two service areas, when it registers with a new base station and hence a new service area it retains its registration with at least one service area with which it is already registered, thereby creating its own customised enlarged registration area.  Thus the transmission overhead created by the registration procedure is reduced.

Title: Method and an apparatus for producing lining for slender supporting structural units
Inventor: SORGE WERNER
IPC: E04G13/02
Filed: 1988-01-27
Granted: 1992-09-01
Abstract: ABSTRACT OF THE DISCLOSURE A method  of  producing  structural  supports for use particularly in mining applications includes the use of a relatively rigid and cylindrical shell casing.   The  shell  casing  is  separable  along  the plane parallel  to  its  axis,  has  open  ends  and  is closed about a fabric tube which is axially supported therein.  The fabric tube is filled with pressurized liquid  building  materials  such  as  concrete.   Once filled  within  the  casing,  the  pressure  of  the building material forces the liquid component thereof out of the tube  laterally and through perforations provided in the shell casing to drain the liquid away from the building material in the tube.  The casing and tube are of size such that the remaining building material,  which  will  constitute  a  pillar,  extends completely between the surfaces it is to separate and support.  Once the liquid has been drained from the building material within  the  fabric  tube and  shell casing, the shell casing can be removed even before the remaining building material  is hardened  into a pillar  reinforced  with  an  outer  fabric  tube.   The shell  casing  can  then be  reused  for  producing additional fabric reinforced pillars.
