Abstract: 854,773. Ratchet clutches. NAPIER & SON Ltd., D. April 27, 1959 [May 20, 1958], No. 16194/58. Class 80 (2). A ratchet clutch of the Legge type, comprising a driving-shaft 10 formed with a quick-pitch thread 12 supporting an intermediate clutch sleeve 13 screwed leftwards of Fig. 1 to engage clutch teeth 14 with clutch teeth 15 on a driven shaft 11, has a friction coupling 16, 18 between the driving and driven shafts to initiate screwing of the clutch sleeve along the driving-shaft on over-running, the coupling consisting of a radial flange 16 fast with the driven shaft engaged frictionally by a dished spring washer 18 carried on a coupling sleeve 19 slidably mounted by axial splines 20 upon the clutch sleeve 13 and also connected through camming teeth 25, 26 with a flange 27 fast on the driving-shaft. The arrangement is such that at the commencement of over-running in the clutch-engaging direction between the driving and driven shafts 10, 11, the camming teeth 25 on the coupling sleeve 19 ride up the camming teeth 26 on the flange 27 and the coupling sleeve slides leftwards of Fig. 1 until the flat tips 28 of the camming teeth engage, the force frictionally engaging the dished spring washer 18 and the radial flange 16 thereby being increased. Conversely, when the clutch is disengaged, the camming teeth 25, 26 and the coupling sleeve 19 are restored to the rest position, thus reducing the friction between the coupling parts 16, 18 so that less wear takes place. As shown, the clutch teeth 14, 15 have inclined flanks to one side in order to facilitate their engagement.

Abstract: 959,209. Telegraphy. ELLIOTT BROS. (LONDON) Ltd. May 4, 1962 [May 4, 1961], No. 16284/61. Heading H4P. In a data-routing system the data from each of a plurality of out-stations is identified by the addition of extra digits at a device which merges the data from the stations, the data being passed sequentially over a single channel to the central station at which it is stored according to its identifying digits. The central station adds address digits to the data which is then passed over a single channel to a distributing unit which routes the data to its destination. The embodiment described comprises a central station 5 which includes a computer, having single input and output channels. Units 1, 2 each receive n-bit words from four data sources. Both units 1, 2, described with reference to Fig. 2 (not shown), scan their four inputs at high speed, the presence of data on an input causing the scanning to stop and two bits which identify the input channel to be added. When this has been completed scanning starts again. The outputs of units 1, 2 are a sequence of words having (n+2) bits, and act as data sources for a unit 3 which operates in a similar manner to units 1, 2. Unit 3 adds one bit to indicate the input channel. The resultant series of (n+3)-bit words is fed to the central station, where the n-bits are stored and three routing digits derived. The central station output is distributed by unit 6 to one of two channels, each channel feeding units 8, 9 which distribute the data to the appropriate address. Units 8, 9 are described with reference to Fig. 3 (not shown).

Title: Process for the dyeing of textile materials of poly acrylonitrile or asymmetric dicyanoethylene
IPC: C09B1/00
Filed: 1956-05-28
Abstract: Textile materials of polymers of acrylonitrile or of asymmetrical dicyanoethylene or copolymers thereof are dyed from an acid bath with a basic arylamino-anthraquinone which is substituted in the aryl group by an aliphatic radical or by an aliphatic radical containing one or more hetero atoms such as -O-, -S-, -NR- or -SO2-, and which contains an unsubstituted, substituted or quaternized amino group bound to the aryl group by the aliphatic radical.  When the amino group is substituted by alkyl groups the latter may form a heterocyclic ring with the nitrogen atom.  The aryl radical and the anthraquinone radical may be substituted with, e.g., halogen, hydroxyl, alkoxy, amino or substituted amino groups.  Numerous examples are given.  The dyestuffs may be obtained by reacting halogen-anthraquinones with amines of the formula: <FORM:0788708/IV (b)/1> wherein Ar is an aryl radical, R and R1 are hydrogen or alkyl radicles which together with the N atom may form a ring, Z is an aliphatic chain which may contain hetero atoms and Y is one or more substituents such as halogen, hydroxyl, amino or substituted amino groups.  In the case of derivatives of 1-amino-4-aryl-amino-anthraquinone there may be obtained by reacting 1 - amino - 4 - bromo - anthraquinone-2-sulphonic acid with amines of the above formul  and then splitting off the sulpho group.
