Title: Digital signal recording apparatus
IPC: G11B20/18
Filed: 1988-10-27
Abstract: Digital signal recording apparatus in which a sampling frequency 
of digital information signals to be recorded cannot be completely 
divided by a frequency of a unit of an error correcting code consisting 
of a plurality of samples in the encoding process of the error 
correcting code. An analog to digital converter (2) converts analog 
input signals into digital information signals, an encoder performs 
encoding of the error correcting code with respect to the digital 
information signals, and memory means (5,6) are provided for the 
encoding. An address generator (7) controls the write and read 
operations of the memory (5,6). The apparatus also includes 
means (64 to 67) for setting two or more numerical values each of which 
is an integer value (e.g. 800, 801) near the quotient obtained when the 
sampling frequency is divided by the frequency of the unit of the error 
correcting code. A count value (NA) of the number of input samples to 
be recorded and the count value (NB) selected from the two or more 
numerical values are compared (63) and a count comparison signal (S J ) 
is output. A word number control circuit (41) determines the number of 
samples included in the unit in accordance with the count comparison 
output signal (S J ), and the address generator (7) is controlled by 
means of the word number control circuit (41).

Title: Method for electrically measuring the concentration of acids
IPC: G01N27/416
Filed: 1989-03-01
Abstract: In a method for the electrical measurement of the concentration of acids a measurement electrode (11) consisting at least predominantly of crystalline graphite is arranged in an acid (12) having anions which form graphite intercalation compounds with graphite. The measurement electrode (11) is then intercalated by generating in the measurement electrode (11), at a variable positive potential, a current of such a size that the anions of the acids (12) can from graphite intercalation compounds with the graphite. The current is maintained until the intercalation compounds have formed at the surface. The potential at the measurement electrode (11) is then measured and used as a measure for the acid concentration. The measurement electrode (11) is subsequently deintercalated again.

Patent EP-0369530-A3 (EP)
IPC: G01K3/00
Filed: 1989-11-08
Abstract: In order to sense the temperature of an integrated circuit 
chip, a semiconductor junction device (D1) integrated on the chip 
is used to generate a first signal (V₁) having a known variation 
with temperature. A second signal (V₂) is generated by passing a 
PTAT current (I₂) through a resistor (R1) so that the second signal 
(V₂) has a known variation with temperature which is opposite in 
sign to that of the first signal (V₁). The two signals are 
compared (42) to generate an output signal (0T) which is dependent 
on whether the temperature of the chip is below or above a 
predetermined threshold temperature. The current (I₁) through the 
junction device (D1) is also PTAT, enabling a more accurate 
definition of the threshold temperature in terms of integrated 
circuit parameters.

Title: Fire detector
IPC: G08B17/12
Filed: 1990-07-20
Abstract: A fire detector contains at least one sensor element (16) which detects the heat emanating from a fire. The sensor element is constructed as a thermocouple (16) whose reference junction is thermally connected to a heat sink (18) which stores the heat and whose temperature corresponds to the mean temperature of the room. The temperature of the measuring point of the thermocouple is influenced both by absorption of radiant energy and by heating due to heat conduction. In the event of a fire, energy components of both types of heat transmission are detected by the thermocouple, so that the fire detector reacts to fires with a high sensitivity. In one embodiment of the invention, a test sensor (82, 84) which receives a test radiation (94) is arranged near the thermocouple (16). The test sensor (82, 84) generates a test signal with the aid of which the degree of pollution of an upstream protective glass (80) is detected.   <IMAGE>

Filed: 1990-03-19
Abstract: An infusion pump includes a system for sensing the near end and end of 
syringe positions of a piston 6 in a syringe 12 by means of 
a permanent magnet 14 located in a disengagement head 8. The magnet 
14 as it passes a switch 16 located adjacent the syringe 12 within the

pump motor encoder 22. The sum of the pulses received from the 
encoder 22 is compared with a preset value which once reached causes 
an alarm to be operated thereby indicating a near end or end of 
syringe position of the syringe piston 6 relative to the syringe 12.

Title: Process for the production of alkaline earth alkoxides with spherical particle habit
IPC: C08F4/00
Filed: 1991-10-16
Abstract: Alkaline earth metal alkylates having a spherical particle habit are prepared by dissolving an alkaline earth metal alkylate in a solvent, adding a second solvent which dissolves the alkaline earth metal alkylate only with difficulty or does not dissolve it at all, but which is homogeneously miscible with the solution of the alkaline earth metal alkylate in the first solvent, removing the first solvent and then removing the second solvent. The particle size can be controlled by means of the shear gradient during the precipitation or by the use of emulsion stabilizers. Emulsion stabilization leads to particles in the size range 0.5 to 20  mu m with a particularly narrow particle size distribution. Catalysts for polyolefin synthesis can be prepared on the basis of magnesium alkylates prepared by the process according to the invention. The polymer is advantageous with respect to particle habit and particle size distribution, compared with the prior art. A narrower particle size distribution, and thus a reduction in undesired oversize and undersized particles, and a smoother surface structure are achieved.
