Title: Disc playing apparatus
IPC: G10H1/00
Filed: 1989-07-21
Abstract: An apparatus for playing a disc on which, in 
addition to a coded information signal, a digital 
information signal divided into blocks is recorded as a 
subcode together with a block identification signal for 
identifying the blocks, comprises a reading device for 
reading the coded information signal and the subcode from 
the disc, a decoder for decoding the subcode to produce 
an information signal, a repeater for repeating the 
subcode read out by the reading device to the decoder in 
response to a repeat command, and a controller for 
controlling the reading device and the repeater. The 
controller issues, in response to a command, a jump 
command for moving an information reading point of the 
reading device across M (M is a natural number) tracks in 
a direction retracing a reading direction every time a 
predetermined time period corresponding to the relative 
position of the information reading point in a radial 
direction of the disc elapses; detects, during a period 
between issuing of the jump command and issuing of the 
next jump command, an N-block period, in which N (N is a 
natural number) blocks of the subcode are read, by a 
block identification signal obtained from an output 
signal of the reading device; and supplies the repeating 
command to the repeater only during the N-block period.

Abstract: Bisher werden die wärmeformbeständigen Schaumstoffe auf der Ba­
sis von Polyphenylenoxid und einer vinylaromatischen Verbindung 
in der Weise hergestellt, daß die vinylaromatische Verbindung in 
Gegenwart von Polyphenylenoxid polymerisiert wird. Das fertige 
Polymerblend wird dann granuliert, im Extruder mit dem Treibmit­
tel nachbeladen und anschließend aufgeschäumt. Dieses Verfahren 
ist aufwendig und kostenintensiv.  
     Nach dem erfindungsgemäßen Verfahren wird das schäumbare Polyme­
risat in einem einstufigen Verfahren hergestellt, d. h. die Be­
ladung mit dem Treibmittel erfolgt bereits während der Polymeri­
sation. Außerdem werden durch eine spezielle Zugabereihenfolge 
der Edukte Reaktorwandanbackungen verhindert, was zu einer Aus­
beutesteigerung führt. Anschließend wird aufgeschäumt.  
     Die aus den schäumbaren Polymerisaten hergestellten Schaumstoffe 
werden bevorzugt zur Wärmeisolation eingesetzt.

Title: Means and methods for measuring a parameter
IPC: G01C19/72
Filed: 1989-09-11
Abstract: Means and method for measuring the magnitude of a 
parameter related to serrodyne modulation of an 
integrated optic phase modulator are disclosed. The 
phase modulator is viewed as a repository of angle 
information, in the form of charge. As a result of 
this insight, a new measurement technique may be 
employed to draw that charge off in a controlled 
fashion and achieve a much more reliable indication of 
the measured parameter. For example, a quantity of 
charge stored in the phase modulator is measured (158,160) and, 
in response to monitoring a first selected quantity of 
stored charge, a measuring signal (174) is provided for a 
selected duration. A second selected quantity of 
charge is then discharged (180,182) from the phase modulator(150) in 
response to the measuring signal. The same second 
selected quantity is discharged each time the stored 
charge reaches the first selected quantity. 
Occurrences of said measuring signal are counted (200) as an 
indication of the magnitude of the parameter.

Abstract: The invention provides a metallocene catalyst for use in 
preparing syndiotactic polyolefins. The catalyst comprises a 
bridged metallocene in which one of the cyclopentadienyl rings is 
substituted in a substantially different manner from the other 
ring. It was discovered that this type of catalyst is highly 
syndiospecific, and it also produces a polymer with a novel 
microstructure. The invention further includes the use of one or 
more of the catalysts in a polymerization process. The catalyst 
is generally described by the formula   
 
 R″(CpR n )(CpR′ m )MeQ k       
 
wherein each Cp is a cyclopentadienyl or substituted 
cyclopentadienyl ring; each R n  and R′ m  is the same or different 
and is a hydrocarbyl radicals having 1-20 carbon atoms; R″ is a 
structural bridge between the two Cp rings imparting 
stereorigidity to the catalyst; Me is a group 4b, 5b, or 6b metal 
from the Periodic Table of Elements; each Q is a hydrocarbyl 
radical having 1-20 carbon atoms or is a halogen; 0 ≦ k ≦ 3; 0 ≦ 
n ≦ 4; 1 ≦ m ≦ 4; and wherein R′ m  is selected such that (CpR′ m ) 
is a sterically different ring than (CpR n ).

Title: Auxiliary signal transmission in a communication system for high bit-rate digital signals
IPC: H04L25/49
Filed: 1990-11-26
Abstract: According to a prior patent application, the digital user data signal is transmitted in CMI code and, when the code is generated, a binary signal content of the auxiliary signal is allocated to one of the element combinations excluded according to the CMI code rule. Only the start of a one bit or zero bit of the auxiliary signal is marked, so that needle pulses occur at the receiving end at comparatively large intervals only, which pulses are adequate for transmission of the auxiliary signal but severely impede generation of a clock signal at the receiving end. According to the invention, a combination signal is therefore transmitted which contains a clock pulse pattern for simple generation of a clock signal at the receiving end. <IMAGE>

Title: Compressed prefix matching database searching
IPC: G06F17/30
Filed: 1990-06-08
Abstract: Aspects of the invention include a method of conducting a reduced length search along a search path. A node which would otherwise occur between a previous and a following node in the search path is eliminated, and information is stored as to whether, had said eliminated node been present, the search would have proceeded to the following node. During the search, a search argument is compared with the stored information, and the search effectively progresses from the previous node directly to the following node if the comparison is positive. In preferred embodiments, some nodes provide result values for the search, and a node is eliminated only if its presence would not affect the result value for the search. In another aspect, the invention features a method of conducting a two mode search of reduced length. For a first mode of the search, nodes along a search path are provided, at least some of the nodes including one or more pointers pointing to other nodes. A search argument comprising a series of search segments is provided, some values of segments of the argument ccrresponding to nodes along the search path, some other values of the segments relating to a second mode of the search. Indicators associated with nodes are provided, each indicator indicating the segments corresponding to the second mode. The search path is searched by processing successive search segments by inspecting the indicator associated with each node, and proceeding to the second search mode if the indicator indicates that the segment relates to the second mode.

IPC: G06Q40/06
Filed: 1990-05-30
Abstract: An automated system for managing one or more large investor 
portfolios containing both cash and numerous, diversified securities 
in a real time environment provides added liquidity to the 
securities markets while maintaining predetermined portfolio 
objectives for each portfolio. The disclosed system uses data 
processing equipment to place buy and sell orders on securities 
markets and with automated brokers to execute trades directly 
between users of the system and external markets. Holders of such 
large, diversified portfolios have usually been long-term investors. 
The system allows active market participation by such investors 
whereby they provide added liquidity and depth to the securities 
markets while overcoming problems caused by trader identification 
and the inability to enter, change or execute orders in a real time 
environment. The system monitors and analyzes a variety of factors 
which effect trading decisions in a vast number of securities. Such 
factors include other security trades, price and size quotations and 
financial ratios for particular securities. This information is 
further analyzed in relationship to each investor portfolio using 
the system to determine what transactions might benefit the 
portfolio by seeking to provide an incremental return while 
accommodating the basic portfolio objectives. These objectives may 
be changed at the election of the investor at any time. Orders 
 
 
representing such transactions are entered by the system and 
executed in real time either internally between system users or 
externally with computerized brokers and/or stock exchanges and 
markets.
