Title: Modular data storage directories for large-capacity data storage units
IPC: G06F17/30
Filed: 1988-03-23
Abstract: An updatable and expandable directory structure and resultant 
access procedures emulating a write-once or indelible record 
medium (20) to a rewriteable record medium as to accessing 
characteristics. The directory is indexed; one directory 
header for a first set of files indexes another set of 
files. Sector clusters or data extents are managed such that 
random recording from any file proceeds independently of 
write-once characteristics. The directory is stored on the 
medium as data is recorde. Each directory entry contains an 
archival history of recording of a related data file in the 
medium. Both logical and physical addressing is employable.

Title: Compact cooling water treatment plant
IPC: C02F9/00
Filed: 1988-08-25
Abstract: In a process and equipment for treating circulation water of open circulation cooling systems, preferably in cooling tower circulation systems, a solution is to be found which simplifies the monitoring and treatment of circulation water of open cooling systems and, in particular, makes this possible over a long period without laboratory analysis and manual monitoring. 
<??>This is achieved in the process according to the invention by arranging that at a preferred location at least a part of the flow is continuously diverted from the circulation water and flows through a compact and standardised modular unit for the treatment of circulation water, in which successively and automatically, the pH of the partial stream of water is determined and, if necessary, depending on the measured pH, acid is metered in to establish a desired pH, the conductivity of the partial stream of water is determined, preferably inductively and, if necessary, depending on the measured conductivity value, a clarifying unit is activated, corrosion protective agent is added, if necessary, to the partial stream of water as a function of the amount of additional water added to the circulation water to make up for losses, at phased intervals organic and/or inorganic biocides are separately added to the partial stream of water through further metering devices and the partial stream of water is filtered in a filter with automatic back washing, and subsequently the partial stream of water is fed back continuously to the circulating water.

Title: Method and apparatus for repairing the linings of metallurgical ladles
IPC: B22D41/02
Filed: 1988-10-28
Abstract: A method and an apparatus by means of which the worn surface of the lining (3) of a steel ladle (1) can be removed while remaining true to the original contour, in a uniform layer thickness. Tools (30) on flexible displaceable arms (27) are pressed against the inner circumference (4) of the lining.

Title: Reinforcing a grassed surface
IPC: E01C13/08
Filed: 1988-09-28
Abstract: It is highly desirable to reinforce the grassed 
surface layer of a sports ground in order to reduce 
damage to the surface, e.g. from horse racing or from 
playing football. In order to provide a good surface 
layer, a biaxially-orientated, integrally-extruded

of sand 2 strengthened with small, flexible, 
randomly-placed, plastics material mesh pieces. A top 
dressing 3 is put on top of the mesh structure layer, 
grass 4 is seeded or planted, and a machine is then used 
after the grass has grown to slit the mesh structure 
layer into pieces 1 which may be e.g. 100 x 100 mm or 
150 x 150 mm, each having a number of complete mesh 
openings. If a piece 1 is caught by a horse's hoof or

Patent EP-0351704-A3 (EP)
IPC: F16H23/00
Filed: 1989-07-12
Abstract: A mechanism for generating oscillatory motion 
omnidirectionally transforms rotating motion in which the 
rotating member is continuously rotated unidirectionally into 
any number of simultaneous arcuate motions intersecting at 
predetermined angles. This mechanism includes a disk-shaped 
body (1) rotatably mounted and swept in a circle so that it 
completes two periods of rotation over the course of one period 
of sweep. The altitude of the disk-shaped body always intersects 
a point on an imaginary line (L), regardless of the angle of 
inclination (A) of the disk-shaped body. This imaginary line (L) is 
perpendicular to the circularly swept path of the disk-shaped 
body at the center of the circularly swept path. Points on the 
circumferential edge of the disk-shaped body describe an 
infinite number of arcs as they move around the circularly swept 
path. These arcs intersect at a common point from an infinite 
number of angles. Any number of desired arcs intersecting at 
any angle can be obtained by selecting points on the 
circumferential edge of the disk-shaped body describing those 
desired arcs. This apparatus is the basis for improvements in a 
variety of existing devices such as mixers, grinders, drills, 
pendulum devices, centrifuges, signal lights, electric shavers, 
massagers, scanning devices such as ultrasonic, x-ray, radar and 
computer memory scanners, optical cameras and projectors, 
dispersing devices, assembly lines, robots, energy bombardment 
chambers, amusement rides and educational toys.

IPC: G06F13/28
Filed: 1989-03-16
Abstract: A direct memory access controller coupled to a 
system bus (15) of a system for controlling data 
transfers through a channel, in which the operation is as follows. A 
request handler receives a transfer request (29a) 
generated by a device connected to the system bus. A 
transfer control information register (25) stores 
transfer control information used for obtaining transfer 
control information necessary for executing the data 
transfer by a next transfer request supplied from the 
request handler. A temporary register (24) stores the 
transfer control information necessary for processing 
the next transfer request. A transfer control 
information setting circuit (27a, 27b, 28a, 28b) 
generates the transfer control information necessary for 
processing the next transfer request on the basis of the 
transfer control information registered in the transfer 
control information register during the data transfer by 
the present transfer request and then renewing the 
transfer control information and temporary registers 
with the generated transfer control information. A 
transfer execution circuit (31, 32) executes the actual 
data transfer through the system bus in accordance with 
the transfer control information registered in the 
temporary register, which is output to the system bus 
therefrom.

Abstract: There is provided a method and apparatus for forming an 
image (8) which includes providing a recording composition 
capable of changing its adhesivity corresponding to the 
polarity of a voltage applied thereto between a pair of 
electrodes. The recording composition has a transfer 
characteristic having a tendency to change by loss of at 
least one component of the recording composition. A 
voltage is applied between the pair of electrodes to attach 
the recording composition to one of the pair of electrodes. 
Any such change in the transfer characteristic 
of the recording composition is detected during the 
process. In response to any change in the transfer 
characteristic additional component is added to the 
recording composition to compensate for that change.
