Abstract: A special purpose communications protocol processor (CPP) provides more 
efficient processing of layered communication protocols -- e.g. SNA 
(Systems Network Architecture) and OSI (Open Systems Interconnection) 
-- than contemporary general purpose processors, permitting hitherto 
unavailable operations relative to high speed communication links. The 
CPP contains special-purpose circuits dedicated to quick performance 
(e.g. single machine cycle execution) of functions needed to process 
header and frame information, such functions and information being of 
the sort repeatedly encountered in all protocol layers, and uses instr­
uctions architected to operate these circuits. The header processing 
functions given special treatment in this manner include priority 
branch determination functions, register bit reshaping (rearranging) 
functions, and instruction address processing functions. Frame 
processing functions so handled include CRC (cyclic redundancy check) 
computations, bit insertion/deletion operations and special character 
detection operations.

Title: Device for conveying and for controlling the movement of roller pallets
IPC: B65G1/06
Filed: 1990-03-02
Abstract: In a device for conveying and for controlling the movement of roller pallets or roller mounting units (17) with a plurality of pressure elements (30a) which can be brought into contact with the pallets, a solution is to be provided by means of which roller pallets can be conveyed in corresponding bearings in a simple manner without considerable mechanical outlay and with gentle mutual stressing of the contacting elements. This is achieved in that the pusher elements are designed as elastic rollers (30a) which contact the lower planar surface of the pallets (17) in the conveying movement (arrow 36a), these rollers (30a) being impeded in their rolling movement in the pushing direction by detents (34a, 35a) which contact the rollers. <IMAGE>

Patent EP-0377505-A3 (EP)
IPC: B01L7/00
Filed: 1990-01-04
Abstract: It is known to use evaporation caps or 
covers to seal the tops of test elements when they 
are in an incubator of a chemical analyzer to prevent 
evaporation of sample fluids. However, as sample 
fluid can protrude from the test element because it 
is not fully absorbed (depending on the nature of the 
test element), this excess or protruding fluid can be 
wiped away as the element is moved into and out of 
the incubator, thereby producing erroneous results 
when the element is read. Described herein is an 
arrangement for an incubator (30) which raises and 
lowers evaporation caps (42) covering test elements 
(E) at a loading (A) or unloading (D) station. This 
is achieved by having a fixed camming surface (64, 
64′) which acts on a cam follower (56) carried by 
each cap (42) to raise and lower the cap (42) as the 
associated test element (E) is moved past the camming 
surface (64, 64′).

Patent EP-0428377-A3 (EP)
Title: Dc/dc switching converter circuit
IPC: H02M3/28
Filed: 1990-11-13
Abstract: A two switch, DC/DC converter provides sufficient inductive energy storage at the termination of the "on" period of each switch to alter the charge on the intrinsic and stray capacitance of the combination of switches producing zero voltage across the alternate switch prior to its turn on. A short dead-band between the turn on pulses provided by the control circuit allows time for this transition. Thus the energy stored in the capacitance of the switches is returned to the source and load rather than being dissipated in the switching devices. This greatly improves the efficiency of the converter particularly when operating at high frequency. The unique topology of the converter provides other new and useful characteristics in addition to zero voltage switching capability such as operation at constant frequency with pulse-width-modulation for regulation, quasi-square wave output current, and the ability to integrate the magnetic elements with or without coupling.

Abstract: Image conversion method and apparatus that provides for (a) storing in a first memory a first image field; (b) storing in a second memory a second image field; (c) reading the first and the second memories; (d) simultaneously displaying on a display screen the first and the second image fields as a single image frame; and (e) while performing the step of reading the method includes a step of storing in a third memory a third image field. The first, second and third memories are provided as a frame buffer having a 3x3 memory block organization. For image fields numbered 1, 2, 3, 4, 5...n.. the system of the invention reads the image fields two at a time in accordance with a predetermined sequence given by: 1 and 2, 2 and 3, 3 and 4, 4 and 5, ... (n - 1) and n, n and (n + 1). A high resolution frame length is selected to be longer than or shorter than a television field period. The phase difference between the two is measured and circuitry alters the predetermined read-out sequence to ensure that a field memory to be read will not also be required for simultaneously storing a next television field. <IMAGE>

Patent EP-0541281-A3 (EP)
IPC: G06F11/08
Filed: 1992-10-26
Abstract: A facility is provided for storing in a backup memory (30-1-P) only those blocks of a file, or disk partition, which differ from corresponding blocks forming an earlier version of the file. Specifically, a file is divided into a number of blocks and a "signature" is generated for each such block. A block is then stored in the backup memory only if its associated signature differs from a signature generated for an earlier version of the block. In addition, if two blocks of the current version of the file have identical signatures and are to be stored in the backup memory, then only one of the two blocks is stored in the memory and a simple message indicating that the other block is equal to the one block is stored in the memory for the other block. Further, the application of such signatures is advantageously applied to the opposite case of restoring a file using copies of previous versions of the file that are stored in the backup memory. <IMAGE>

Abstract: To produce slubbing material from a fibre feed, using a card (16) and the like, during the slubbing development the separate slubbings (42, 44, 46, 48) are measured continuously for each running metres. On a deviation of the weight from a nominal value, the cross section of the air passage (50) is varied as a weight correction, leading the air out of the shafts (24, 26, 28, 30) at the flocking stage, at the shaft corresponding to a weight shift in the part-slubbing. Also claimed is an assembly with an air passage (50) in each flocking shaft (24, 26, 28, 30) which is increased or decreased steplessly according to the measured weight of the part-slubbings (42, 44, 46, 48) produced from the flockings (34, 36, 38, 40) in the shafts. Pref. each of the shafts (24, 26, 28, 30) is connected to a monitor (56, 58, 60, 62) located after the card (16), to measure the slubbing weight per running metre. A setting unit (54) for a cover (52) adjusts the working in each shaft according to the monitored readings. The cover (52) has a linear movement, sliding parallel to the sieve forming the air passage. <IMAGE>
