Title: A spinning machine
Inventor: ROHNER JOACHIM
IPC: D01H13/16
Filed: 1986-10-20
Abstract: At each spinning station 10 of a yarn doubling and spinning machine, two fibre bundles 17, 17' run from a drafting mechanism 11 to a combining point 19 from which they are twisted together to form a yarn 23. Each spinning station 10 is provided with a sensor 21 which responds to the breakage of either of the two fibre bundles 22, 22' and also to breakage of the yarn 23 formed from them. To achieve reliable response by the sensor 21 during the spinning of any yarns, the sensor 21 monitors the normal path of one of the two fibre bundles 22, 22' above the combining point 19 or the normal path of the yarn 23 below the combining point 19 for the presence of the respective fibre bundle or yarn, or its sensing region extends from the normal path of the yarn 23 below the combining point 19 beyond the normal position of the combining point 19 towards the drafting mechanism 11. The sensors may be mechanical feelers or as shown photo-electric devices. <IMAGE>

Title: Avoiding wheel spin in motor vehicles by reducing transmission ratio of continuously variable transmission
Inventor: CHAMBERS PETER WILLIAM
IPC: B60W30/18
Filed: 1986-11-14
Abstract: When a signal (22) representing the rotational speed of a driven wheel exceeds a threshold, the transmission arrangement alters the speed ratio of the CVT is altered to reduce wheel speed. The speed of the driven wheel axle (16) is preferably compared with the speed of a non-driven wheel axle (12), the speed ratio of the CVT being reduced if the speed of the driven wheels is greater than that of the non-driven wheels. The arrangement may alternatively sense wheel speed directly. <IMAGE>

Title: Method for obtaining dna, rna, peptides, polypeptides or proteins by means of a dna recombinant technique
Inventor: BALLIVET MARC
IPC: C12N1/21
Filed: 1985-06-17
Abstract: Genes at least partially composed of stochastic synthetic polynucleotides are simultaneously produced wihtin the same medium, the genes thus obtained are introduced into host cells; the independent strains of modified host cells enclosing said genes are simultaneously grown, so as to clone the stochastic genes and to promote the production of the proteins expressed by each of said stochastic genes; the strains of modified host cells are screened and/or selected so as to identify the strains producing peptides or polypeptides showing at least a given property; the identified strains are isolated and grown so as to produce at least a peptide or polypeptide showing said property. Analogously, stochastic DNA orRNA sequences showing at least a desired property can be produced by screening and selecting strains of modified host cells so as to identify the strains enclosing in their genome said DNA or RNA sequences.

Abstract: An endless belt 17 is entrained round rollers 13 to 16, of which roller 16 is located below the plane of the others and bears downwards to tension the belt. The ends of roller 16 rotate in a rectangular frame (Fig. 3) which is supported at its other end by a universal coupling 45, which allows roller 16 to pivot about one vertical and two horizontal axes. Heavy roller 16 acts as a gyroscope, and if belt 17 drifts sideways the roller automatically tilts and restores it to centre. As shown belt 17 is of plastics mesh for dewatering farm slurry, which is gravity filtered and then squeezed between rollers 18, 19. Roller 19 and rotary cleaning brush 31 are driven by a common motor 24. <IMAGE>

Title: Generating convoluted digital video signals
Inventor: HILL GERARD ANTHONY
IPC: H04N5/21
Filed: 1991-04-05
Abstract: To generate a convoluted digital video signal, e.g. one in which each pixel in an output image is derived from the corresponding pixel of an input image and pixels in the neighbourhood of it in proportions determined by a convolution function, the input signal is held in an input framestore 14 the output of which is applied to some of the address inputs of a lookup table 16. An intermediate framestore 24 accumulates intermediate results and applies its output to some of the address inputs of a second lookup table 26. The remaining address inputs of the lookup tables are connected to a control signal input 18. An adder 20 combines the outputs of the lookup tables and recirculates the resultant to the intermediate framestore. The intermediate framestore is capable of being written to or read from with an offset of one or more pixels vertically and/or horizontally, and an offset path is traversed covering all the input pixels which contribute to a given output pixel, finishing up at the original zero-offset position. Other functions can be performed by appropriately re-programming the lookup tables, e.g. special effects such as a "snail trail" for moving objects, fading, colourising, edge enhancement, anti-aliassing and other filtering. At least one of the tables, e.g. 26, may merely give a 1:1 transfer, and for purely temporal convolution the store 14 is transparent. <IMAGE>
