Title: Information recording and retrieval system
Inventor: MAEDA SHIGEMI
IPC: G11B7/00
Filed: 1990-01-05
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE      An information recording and retrieval system used for recording and playing back programs on and from a rewritable  recording  medium  which  includes  absolute addresses;  an  information  recording  area  for  storing programs input from outside the system; and a TOC area for storing supplemental data on the programs recorded in the information recording area.  This system comprises:  (1) a magnetic  coil  and  an  optical  head  which  function  in combination  (a)  to  successively  record  the  items  of supplemental data in the TOC area in such a way that each item of  supplemental  data  is  repeatedly  recorded  a plurality of  times,  each item of  supplemental data  at least comprising an identification number corresponding to a program recorded in the information recording area and the storage location of the program which corresponds to the  absolute  addresses  thereof,  and  (b)  to  store supplemental data on an additionally recorded program at the end of the sequence of supplemental data items in the TOC area;  (2)  a TOC memory for storing  each item  of supplemental data in the TOC area when the item is read without an error, such an item being read at least once at the time the recording medium is mounted in the system;          (3) edit control means for (a) performing an edit control consisting of the steps of  i) judging from the items of supplemental  data  stored  in  the  TOC memory whether  a program  is   recorded  over  another  program  in  the information recording area, ii) selecting one as effective data from the items of supplemental data corresponding to the overlapped programs by a specified rule  if  it  is judged that a program is recorded over another and iii) assigning new identification numbers to the new group of supplemental data items which includes thus selected data item, and for (b) permitting the TOC memory to store the new  group  of  supplemental  data  after  the  editing operation;  and  (4)  restoring  means  for  repeating  a recording cycle a plurality of times, the recording cycle being a process in which each item of supplemental data stored in the TOC memory is repeatedly recorded in the TOC area a plurality of times.   This  arrangement makes  it possible to minimize the amount of data to be renewed in the TOC area when a new program is additionally recorded in  the  information recording area of  a disk in which different programs have been already stored, and allows the system to read supplemental data recorded in the TOC area without an error in a short time.

Title: Bile acid derivatives, processes for their preparation, and use as pharmaceuticals
Inventor: KRAMER WERNER
IPC: C07D213/56
Filed: 1990-09-13
Granted: 2001-11-27
Abstract: Bile acid derivatives of the formula I      W - X - G in which G ie a bile acid radical, W is an active com-pound moiety of a medicament and X is a bonding member between a bile acid radical and active compound moiety, are outstandingly suitable for introducing active com-pounds into the enterohepatic circulation. The compounds I are absorbed and pass into the bloodstream. It is possible in this way, using the natural reabsorption of the bile acids, to achieve improved absorption of non-absorbable or poorly absorbable pharmaceuticals.      W may be, for example, a peptide, an antibiotic, an antiviral substance, an anticancer agent, a hepatoprotec-tive agent, an antihyperlipidemic, a diuretic, a hypoten-sive, a renin inhibitor, a substance for the treatment of cirrhosis of the liver or a substance for the treatment of diabetes.      G is a bile acid radical in the form of the free natural or chemically modified acids, the esters and amides, the salt forms and forms derivatized on alcohol groups. X is a large number of intermediate members or, alterna-tively, a bond.

Granted: 1997-05-06
Abstract: There is described an improved solid waste handling system for screening and grinding solids entrained in an influent liquid  stream  that  utilizes  at  least  one  solids  diverter horizontal rotating screen unit fixedly mounted in the liquid stream such that the flow moves through it and that is partially immersed  in  the  influent  liquid  stream.    The  screen  unit comprises a rigid frame assembly and a screen member mounted for rotation on the rigid frame assembly such that the screen member moves horizontally relative to the liquid stream.  The screen is rotated to cause solids of the influent stream larger than openings in the screen to impact upon an upstream face of the screen to be moved horizontally in the direction of screen movement to one side of the liquid stream.  A solid waste grinder is fixedly mounted adjacent to the screen unit whereby solids diverted from the influent stream are conveyed from the screen to the solid waste grinder and finely ground prior to discharge through an outlet of the solid waste grinder.

Granted: 1994-11-15
Abstract: Abstract of the Disclosure A pipe thawing apparatus has a heat exchanger for heating water.   An electric water pump has an outlet coupled to an inlet of the heat exchanger.  A flexible feed tube is coupled to an outlet of the heat exchanger. The electric water pump has an electric motor that is coupled to a source of electric power through a cyclical power   interrupting   device.      The   cyclical   power interrupting device cyclically connects and disconnects the electric motor of the pump to the source of electric power cyclically turning the electric motor on and off. The water pump thus supplies a pulsating stream of water to the heat exchanger which in turn feeds a pulsating stream of heated water into the flexible feed tube.  The flexible feed tube is advanced in the pipe to be thawed so that a pulsating stream of heated water is directed into the pipe, preferably against the ice to be melted.   A return line is coupled between the pipe and an inlet of the water pump so that the water used by the apparatus is continuously recirculated.     The flexible feed tube has a tip having a spider extending radially therefrom to center the flexible feed tube in the pipe and to facilitate the advancing of the flexible feed tube through the pipe.  The spider comprises a plurality of resilient fingers, preferably four, which extend radially outwardly and backwardly from the tip.
