Title: Motion converting device
IPC: F16H19/00
Filed: 1988-05-31
Abstract: A device for converting the reciprocating movement of at least one piston (8) of an internal-combustion engine (4) into an oscillating rotary movement of at least one shaft (10), the piston (8) being connected via a flexible strip (24) to a winding-up and unwinding region (20) of the shaft (10). The rotational energy existing during rotary movement of the shaft (10) is used at the end of the working stroke of the piston (8) to rotate the shaft (10) further in the same direction of rotation, so that the strip (24) is subsequently wound in the opposite winding sense onto the winding-up and unwinding region (20) of the shaft (10), and the piston (8) is thereby pulled back by the strip (24). Alternatively, two pistons (8) are provided, with a connecting rod (16) between them, together with strips (24, 24') with opposing winding directions, so that, when the one strip is wound up, the other strip is unwound, and vice versa.

Title: Track wheel
IPC: B62D55/22
Filed: 1989-05-05
Abstract: A track wheel consisting of a longitudinal curved track(10) 
mounted in an oval geometry on two support rollers (18,20). The track 
wheel is in effect an oval wheel with two axles. The axles (14,16) of 
the two support rollers are mounted either directly or indirectly 
to the vehicle. The rollers support and guide both ends of the 
track in the small curvatures and transfer vehicle load to a 
surface at the lower curved part of the track.  
     Embodiments include a spring track, a pivot hinged 
segment track and a band hinged segment track, these three track 
designs having similar bending characteristics. The track will 
withstand a high bending load in one direction, where it engages 
a surface, but it will also bend easily in the opposite direction, 
as it is guided over the two support rollers.

Patent EP-0357413-A3 (EP)
Title: Data transfer control circuit
IPC: G06F13/42
Filed: 1989-08-31
Abstract: A novel data transfer control circuit is 
disclosed in which a comparator (16) compares an output 
of a data transfer request signal pulse counter (9) 
with an output of a full adder (15) which is made up of 
a counter output of data transfer acknowledgement pulses 
plus a predetermined number of words by which a data 
transfer request signal pulse is capable of leading a 
data transfer acknowledgement signal pulse. This 
comparator is used to stop transmission of a data 
transfer request signal when the counter output of the 
data transfer request signal becomes equal to a full 
adder output represented by a counter output of a data 
transfer acknowledgement pulse plus a predetermined 
number of words by which the data transfer request signal 
pulse is capable of leading the data transfer acknowledge­
ment signal pulse thereby to control the transmission 
of the data transfer request signal for data transfer 
in synchronous mode according to SCSI specification. 
A comparator for comparing the counter output of a data 
transfer request signal pulse with a counter output of 
a data transfer acknowledgement signal pulse is also used 
in such a manner that when the counter output of the 
data transfer acknowledgement signal pulse becomes equal 
to that of the data transfer request signal pulse, the 
transmission of the data transfer acknowledgement signal 
 
 
is stopped thereby to control the transmission of a data 
transfer acknowledgement signal pulse, thus controlling 
the transmission of the data transfer acknowledgement 
signal at the time of data transfer in an asynchronous 
mode of SCSI specification. When the circuit is set 
to the transmitting end of data transfer acknowledgement 
signal, the data transfer acknowledgement signal for 
the last transfer byte is held true at the time of data 
transfer in asynchronous mode of SCSI specification, 
and when data transfer in synchronous mode is decided 
for the next data transfer, the data transfer aknowledge­
ment signal is rendered false after completely preparing 
for the next data transfer, thus preventing the data 
misfetching for the data transfer in synchronous mode.
Patent EP-0363217-A3 (EP)
Title: Athletic shoe with bendable traction projections
IPC: A43B13/26
Filed: 1989-10-06
Abstract: There is disclosed an athletic shoe having grooves in a ground 
engaging surface of a sole formed concentrically about a pivot point 
in the ball portion and having traction projections in the form of bris­
tles or columns embedded in the bottom of the grooves. Free ends of 
the traction projections protrude from the ground engaging surface 
whereby forces on the free ends of the traction projections perpen­
dicular to the grooves, as when a player is accelerating, causes the 
projections to bend against the side walls of the grooves which thus 
support the projections against further bending with the free ends of 
the projections protruding from the outsole to provide traction. 
Forces on the free ends of the projections tangentially to the grooves, 
as when a player pivots, cause the projections to bend into or lay 
down in the grooves and thus offer little or no traction. The ground 
engaging surface of the sole is formed of a material having a low 
coefficient of friction so that the sole can move or pivot relatively 
freely once the projections have bent into the grooves.
Patent EP-0373764-A3 (EP)
Title: Correction of random and burst errors
IPC: G06F11/10
Filed: 1989-11-10
Abstract: A method and means is described for correcting multiple error bursts in 
data recorded on a storage medium in blocks, comprising a plurality of 
sub-blocks. After reading the data, decoded block check syndromes are 
algebraically summed with estimated block check syndromes to provide a 
set of syndromes for a code for locating sub-blocks having an error 
burst. This set of syndromes is decoded to identify each sub-block 
having an error burst. Concurrently block level syndromes are computed 
to identify the locations and values of errors within the sub-blocks 
having error bursts. During writing, the data in all sub-blocks of a 
block is encoded and block level syndromes are generated for these 
sub-blocks. These block level syndromes are multiplied by a series of 
preselected weighting factors (α l  ... α l(B-1) ) according to the 
location index l of the sub-block within the block and as multiplied, 
each is stored in a different one of B buffers. These are cumulatively 
summed to produce block check syndromes, which are encoded after the 
last sub-block of the block is written to provide check bytes for their 
protection. These check bytes and the weighted cumulative sums are 
stored on the medium at the end of the block as block check syndromes. 
, and more specifically relates to such a method and means which 
includes error correction code (ECC) for which decoded and estimated 
block check syndromes are generated
