Title: A skein with the threads crossed in the form of a figure eight for the examination of the yarn and an apparatus for the production of the skein
IPC: B65H54/56
Filed: 1926-06-02
Abstract: 268,583. Zanchi, A. June 2, 1926. Winding or reeling machines; stop - motions. - For convenience in inspecting yarns, especially artificial silk, in order to remove imperfect yarns as regards structure and colour, the yarns are wound in skeins in 8-form in a single layer as shown in Fig. 1, on two parallel rods 7, 7<1>, Fig. 5, by means of a guiding rod 6 mounted on a cross stay 19 sliding on two rods 20, 20<1> which are reciprocated and rocked by a crank 14 connected to the rods 20, 20<1> by a rod 15 sliding in a pivoted guide 16 mounted on a small column 17. The yarns are fed from a spool 35 over pulleys 38, 39 each mounted on elastic rods to compensate for variation in the winding speed. The part 19 is connected by cords 21 passing over pullays 22, 22<1> to the part 16, so that the longer axis of the skein produced is twice the throw of the crank 14. The rods 7 are mounted on a carriage 24 provided underneath with a half nut engaging a screw 27 which is rotated by a pawl engaging a toothed wheel 34 and operated by an eccentric 33 on the main shaft. The drive of the machine is from a pulley 31 freely mounted on a shaft 32 and having a pin 47 engaging a spring 46 splined on the shaft. When the yarn breaks, an elastic lever 51 springs upwards and a lever 52 is caused to engage a lever 53 which pushes down a catch 50 and releases an arm 49 pivoted at 44. An extension 43 of the arm 49 operates a sliding sleeve 45 normally urged by a spring towards a fixed plate 42 and one or other of the stops 48 thereon engaging a spring 46' carried by the sleeve 45 brings the machine to rest. The rods 20, 20<1> may be dispensed with and the part 19 secured to the rod 15, when the longer axis of the skein will be equal to the throw of the crank 14.

Title: Improvements in or relating to refractory materials
IPC: C04B41/50
Filed: 1943-08-27
Abstract: The particles of basic refractory materials such as chromite or periclase are coated with a substantially aluminium-free plastic hydrous magnesium silicate such as that found near Hector, California, the ratio of silica to magnesia in the silicate being at least 2 : 1.  The refractory materials are crushed to the desired mesh and are coated with the silicate which is in the form of a thick gelatinous suspension in water, and the resultant material may be pressed into brick form and fired or be mixed with a binder, e.g. waste sulphite liquor, and applied as unfired brick; alternatively, the refractory material and silicate may be mixed dry and finally tempered with water.  The silicate may be applied alone or in admixture with other materials such as magnesium or calcium hydrate, which, when fired, unite to form a magnesium or calcium silicate. The silicate may be added in amounts between 3 and 15 per cent.  A small amount of borax may also be added.

Patent GB-1474010-A (GB)
Title: Method and apparatus for determining the position of a body
IPC: G06V10/24
Filed: 1975-04-07
Abstract: 1474010 Position determination BENDIX CORP 7 April 1975 [16 May 1974] 14175/75 Heading H4D To enable a succession of like samples 18, Fig. 1, to be placed in the same position on a work surface 14, a reference sample is first placed on the surface in the desired position, its centroid determined by scanning its outline in a raster pattern, Fig. 8, by means of a vidicon 24 and its shape/orientation determined by changing the scan pattern to that of circles of increasing radius centred on the centroid to generate a video signal or reference ("signature") indicative of said shape and orientation when the circle intercepts the outline. The first "run" sample is placed on the surface and the raster scanning repeated as for the reference sample to determine the centroid position whereby a single circular scan at the radius giving the reference "signature" is enabled to give a run "signature", said run "signature" being correlated with the reference "signature" to determine (a) if the run sample is the same shape as the reference sample (high degree of correlation) and (b) if (a) is established, the orientation of the run sample with respect to the reference by comparison of the phases of the "signatures". Any out of orientation alignment error is corrected by a manipulator arm 34. To determine the co-ordinates C x  and C y  of the sample centroid, the interceptions, e.g. X1A, X2A, Fig. 8, of the raster scan with the sample are used, Fig. 7, to give (a) the width of the scanned part of the sample, i.e. X 2 -X 1  (140) and (b) the x co-ordinate of the centre of said part, i.e. (X 1 +X 2 )/2 (138). The moment of each part X 1 -X 2  about the X axis is (X 2 -X 1 )y (150) and that about the y axis is (X 2 -X 1 ).(X 1 +X 2 ), (144). The total moments M x  and M y  are #(X 2 -X 1 )y and #(X 2 +X 1 )(X 2 -X 1 ) and are produced by recursive store and adding circuits 152, 154 and 146, 148. The area A of the sample is #X 2 -X 1 , produced by store 156. Division circuits then produce the centroid co-ordinates from C x =M x /A, C y =M y /A. During the circular scanning of the reference sample the video input of each scan is correlated with the previous scan to determine which scan contains the most information, i.e. is most useful as a "signature". The scans are arranged into groups to aid in this determination. For the correlation determination between the reference and run "signatures", the reference video and run video are stored in respective n bit shift registers. At the end of each correlation by reading out the registers into an exclusive OR circuit, the video in the reference register is advanced by one bit relative to that in the run register, and the correlation repeated, the summed inverse of the OR circuit output giving the degree of correlation. The amount of shift between the registers corresponding to a max correlation gives the relative signature phase and run sample orientation, Fig. 11 (not shown).
