IPC: H04N9/82
Filed: 1987-04-15
Abstract: A method and apparatus for playback of a data recording 
disc which contains a CD area in which a signal such as an 
audio signals recorded in digital form and a video area in which 
a FM-modulated video signal is recorded with a digital audio 
signal superimposed thereon. The position of a data detection 
point of a pickup is monitored, and the equalization and ampli­
fier gain of components of a digital demodulation system are 
automatically changed in accordance with playback being ex­
ecuted of the CD area or the video area, so that a single 
demodulation system is used for both digital signals from the 
CD area and digital signals from the video area. In addition, the 
frequency characteristics of components in servo systems 
which conrol the spindle motor, pickup carriage, etc. of the ap­
paratus are automatically changed over for CD area and video 
area playback respectively, to provide stable servo control in 
spite of the high speed of rotation during video data playback.

Title: Stack control
IPC: G06F7/00
Filed: 1988-07-28
Abstract: A stack control is assigned at a multi-bit-computer, where one or more memories are present and a part of the memory is called a run time stack. The uppermost part of the stack is implemented as stack register set and the recent or the most recent stack frames (generations) are held in this register set. The memory address of the first register to be stored is hold in a memory pointer, which is incremented when stack registers are saved to memory and is decremented when stack registers are restored from memory. According to the invention, there is a variable stack frame length, whereat the stack pointer is ommitted. Thus, the frame pointer can be substantially shorter and is being implemented as part of the status word in the status register. Therefore, a whole cycle and a whole register for storing the frame pointer is saved. This renders a simple control and provides one additional register per frame for the user program. The saving over stack controls according to the state of the art is 33% of controlled registers per stack frame.

Title: By impact expandible plug
IPC: F16B13/12
Filed: 1988-12-23
Abstract: Impact expansion dowels are known for insertion in undercut drilled holes in masonry, in which an expansion sleeve is pushed onto an expansion body supported on the base of the drilled hole when impacts are applied. The expansion region of the expansion sleeve in this case engages in the undercut of the drilled hole in a positively locking manner. In order that a tensile force applied to the expansion sleeve does not pull the expansion sleeve off the expansion body, the expansion body has a shank with a locking profile which engages into a corresponding locking profile of the inner hole of the expansion sleeve. In the region of the locking profile, the expansion sleeve is slotted and is thus designed to be elastic radially. <IMAGE>

Patent EP-0320185-A3 (EP)
IPC: H01J17/54
Filed: 1988-12-02
Abstract: In a thyratron gas discharge device, magnetic 
material 5 is located coaxially with the anode 2 to 
produce a magnetic field between the anode 2 and cathode 3 
which is substantially parallel to a discharge established 
between them. This causes electrons emitted from the 
cathode 3 to have longer path lengths than would otherwise 
be the case and so the ionisation density within the 
device is increased. This improves the operating 
characteristics of the thyratron and results in greater 
utilisation of the cathode 3.

Title: A method and apparatus for continuous nuclear power distribution synthesis
IPC: G21C17/00
Filed: 1988-12-30
Abstract: The present invention provides a power distribu­
tion synthesis method and apparatus that uses a small 
number of local axial power distributions determined from 
less than a full complement of fixed incore neutron 
detectors (16) and a power sharing map produced from a 
full complement of core exit thermocouple (18) temperature 
signals to synthesize the full core (12) power distribu­
tion (62). The localized tilt of the core (12) is 
determined (70 and 72) from the power sharing map and used 
to remove (76 and 82) the tilt from the local distribu­
tion. The tilt adjusted local distribution is assigned to 
symmetric core (12) locations where uninstrumented core 
power values are determined by interpolation (90-120). 
The interpolated, assigned and tilt corrected local 
distribution power values are transformed into the three 
dimensional power distribution using the tilt.

Filed: 1989-06-26
Abstract: Aromatic bischloroformates are prepared by the 
reaction of a dihydroxyaromatic compound such as bisphenol A 
with phosgene in the presence of water, base and an organic 
liquid such as methylene chloride. Initially, a mixture of 
the bisphenol, organic liquid and about 5-15% of the total 
base is prepared, and phosgene is passed into said mixture. 
The remainder of the base is added initially at a constant 
rate, and then only when the measured pH of the aqueous 
mixture is below a targeted value in the range of about 8-11 
and in about 5-10% excess with respect to the phosgene then 
being introduced. This method minimizes hydrolysis of 
phosgene and formation of such by-products as monochloro­
formates and hydroxy-terminated polycarbonate oligomers.

Title: Apparatus for exposing an image of an original film on a photosensitive material in vacuum contact with the original film, and method therefor
IPC: G03B27/20
Filed: 1989-10-31
Abstract: An apparatus for exposure of an image of an original 
film (31) on a photosensitive material (32) held together with the 
original film (31) by vacuum contact between a transparent 
plate and an elastic sheet. The apparatus includes a 
squeegee unit (11) which moves while pressing the elastic 
sheet (1), for forcedly moving the air, thereby speeding up 
the setting of the vacuum contact, and a speed changing 
unit for changing the moving speed of the squeegee unit 
dependent on ease of movement of the air. If the air 
easily moves, the squeegee unit moves rapidly. If it is 
not easy to move the air, the squeegee unit moves at low 
speed, or the squeegee unit stops for a prescribed period 
and after the air is removed, it restarts to move. Thus, 
the removal of the air is carried out rapidly and there 
remains no blowhole.
