Title: Record carrier and tracking signal generator circuit
IPC: G11B7/24085
Filed: 1986-07-29
Abstract: A record carrier for a data storage apparatus has an information layer (19) having tracks (11, 13) for storage of data, the tracks being so arranged and disposed to form a diffraction grating for an incident radiation beam so as to generate a push-pull signal usable as an uncorrected track following signal. The tracks are comprised of longitudinally disposed sectors, each sector having an associated header (24, 44) and associated servo areas. The storage apparatus, in operation, may produce and read detectable modulations in the record carrier by means of directing incident radiation beam to a spot (70) in the information layer (19). The spot is moveable along the longitudinal direction of one of the tracks and perpendicularly across substantially parallel tracks. The storage apparatus, in operation, reads the detectable modulations in a returned radiation beam. The record carrier has a track format in each track comprising discontinuities (41) for generating a correcting signal for correcting said push-pull signal, located in each servo area, qualifier modulations (26, 46) for producing a qualifier signal in the servo area (40) for confirming the coincidence of one of the sector headers under the spot and modulation clocking (21) comprising nonreflective timing pits.
Patent EP-0213801-A3 (EP)
IPC: B41J15/04
Filed: 1986-08-06
Abstract: A circuit arrangement comprises a controller 
(20) for producing a control signal selectively 
indicative of normal and diagnosis modes. Responsive to 
the control signal, an IF stage (12) processes desired 
RF and diagnosis input signals into an IF signal of an 
IF level. Responsive to the IF signal and a reference 
signal of a reference level squelch signal producing 
circuit (15) produces a squelch signal when the IF level 
is lower than the reference level. First and second 
signal generators (26, 27) generate first and second 
threshold signals of first and second threshold levels, 
respectively. The second threshold level is lower than 
the first threshold level. Responsive to the control 
signal, a switch circuit (22) selects the first and the 
second threshold signals as a selected threshold signal. 
A line (29) supplies the selected threshold signal to 
the squelch signal producing circuit as the reference 
signal.

sulphuric acid in the presence of water in an amount 
sufficient to keep the resulting sodium sulphate in 
solution; the extraction of the solution with an organic 
solvent selective for formic acid, in particular methyl 
ethyl ketone and its mixtures with a second solvent; and the 
rectification of the organic phase with the recovery of 
formic acid at a concentration of at least 85% by weight. An 
apparatus for carrying out the above described process is 
also described.

Title: Method and apparatus for indirect blood pressure measurement
IPC: A61B5/02
Filed: 1987-06-19
Abstract: A method and apparatus for the indirect measurement of blood pressure is disclosed. Pressure is applied to a cuff attached to a patient adjacent a blood vessel and a quantity repressentative of the patient's blood pressure is measured as the applied pressure is changed. A table of values of the quantity as the applied pressure is changed is formed. Valves of the table are selected as spurious high and low values in response to predetermined criteria and new values assigned to the selected values which reduces the error in calculating systolic and diastolic blood pressures from the table.

Patent EP-0259183-A3 (EP)
IPC: G01N33/50
Filed: 1987-09-04
Abstract: A method of determining the relative clinical potency 
of a test agent, such as a chemotherapeutic drug or radiation, 
on cells from an individual. A plurality of assay cell samples 
from the individual are treated with a different doses of the 
agent, and the growth of the cell samples measured. An 
"inhibitory value" is then calculated, which is the value of one 
of the dose and dose response, corresponding to a selected value 
of the other one. For drug testing, the inhibitory value is 
preferably the value of the dose which produces a dose response 
selected at a 90% kill. The inhibitory value can then be 
compared with inhibitory values for cells from a plurality of 
other individuals to ascertain the relative clinical potency of 
the test agent. A number of techniques are provided which 
reduce errors associated with such assays so that meaningful 
comparisons can be made.

Title: Device for heating water particularly a hot water boiler
IPC: F24H9/20
Filed: 1988-10-17
Abstract: The invention is based on devices for heating water, in particular a hot water boiler, with a combustion chamber which has an oil- operated or gas-operated burner, one or more heat exchangers and a suction draught blower which is to ensure a low pressure in the chambers flowed through by the smoke gases, specifically in such a manner that the burner is switched off when the prescribed low pressure is not present. In order to be able to carry out a reliable measurement of the internal pressure, the elements serving for determination of the pressure are, according to the invention, arranged in the region of the wall of the device, which serves for installation of the burner; an extensively turbulence-free measuring point is thus selected, which is also practically not exposed to dirtying and other influences. <IMAGE>

Title: Cathode ray tube display system
IPC: H01J29/74
Filed: 1988-11-24
Abstract: A CRT display system in which an electron beam (32) 
is directed in a plane substantially parallel to a faceplate (14) 
carrying a phosphor screen (16) the beam (32) being deflected towards 
the screen.  
     The position of the beam is controlled to correct for 
deviation caused, for example, by the influence of ambient magnetic 
fields. Sensor devices (50, 51) periodically detect during the tube 
operation deviation of the beam from the desired plane and control 
deflector electrodes (37) which return the beam to the desired plane. 
Twisting and lateral shifting of the scanning beam can also be 
corrected. Beam position sensing is accomplished by overscanning the 
beam towards the sensor devices during, for example, field blanking 
periods, so as not to interfere with the display picture.

members (52,53) depending from the under-portions of the 
sealing surface (51) for rotatably mounting the closure 
member (50) within the valve body (20). A shaft (70) which 
is rotatable about a rotating axis (71) provides rotational 
movement to the closure member (50). In particular, the 
shaft (70) is attached to at least one of the spaced sup­
port members (52,53) within the valve body (20) along the 
rotation axis (71) and adjacent the periphery of the bore 
such that when the closure member (50) is rotated to open 
position within the valve body (20), the shaft (70) and the 
attached closure member (50) are located substantially 
radially outside of the central product flow path (23). In 
this way, unobstructed product flow is permitted along the 
flow path (23) through the bore.
