Title: An anthraquinone pigment and the process of its production
Inventor: EHRHARDT KLAUS
IPC: C09B56/12
Filed: 1969-12-29
Abstract: 1278810 Anthraquinone pigment SANDOZ Ltd 29 Dec 1969 [14 Jan 1969] 63018/69 Heading C4P The invention comprises the (3-crystal modification of the pigment of the formula which is characterized by three specific lines in the X-ray spectrum (Cu-Kα e  radiation) at angles of diffraction of 10À33, 11À2 and 11À6 degrees. The # modification is produced by submitting the α-crystal modification which has a characteristic line at 8À4 degrees to grinding at temperatures above 100 C. Grinding assistants, e.g. common salt, Glauber's salt, calcium ferrocyanide or calcium carbonate may also be employed. Grinding takes from 5-100 hours and may be carried out in any form of grinding machine, e.g. ball and roller mills and vibratory grinding equipment. The pigment obtained gives greenish yellow shades on paper, plastics, synthetic and natural resins, rubber and textiles.
Patent GB-731521-A (GB)
Abstract: 731,521. Permutation locks. SIMENCA SOC. ANON. Sept. 6, 1950 [Sept. 17, 1949], No. 21953/50. Class 44. [Also in Group XIX] A permutation lock comprises a series of number-settable bolt-controlling rings 1, 1<SP>1</SP> &c., rotatable within a barrel 13, and a telephonetype setting dial 20 by which digits of the number are registered in turn upon the lowest ring 1 and transferred successively up the series of rings. Transfer is effected by way of toothed wheels 2, 2<SP>1</SP>, &c., intermediate the rings, and movable axially with a central shaft 14 to effect driving engagement with single inwardly directed teeth 16 of the adjacent rings. Forward (counterclockwise) rotation of the dial, commensurate with a digit being registered, is transmitted by way of a gear ring 27 on the dial and an intermediate member 21 to an initial wheel 2‹ similar to the wheels 2, 2<SP>1</SP>, &c. During this forward rotation, moreover, the shaft 14 is given a full turn clockwise (viewed from the right), and arms 15 on the shaft pick up the teeth 16 and reset the rings 1, 1<SP>1</SP> &c., to zero. At this stage, the intermediate wheels 2, 2<SP>1</SP>, &c., are engaged with the teeth 16 of their lower rings so that the initial setting of the rings is transferred to the intermediate wheels. When the dial reverses at the end of the forward stroke, teeth 34 thereon rock a shaft 29 by engagement with a finger 28, and the shaft 29 thrusts the shaft 14 to the left so that the arms 15 shift the intermediate wheels 2, 21 &c. and the initial wheel 2‹ into engagement with the next higher ring. During return of the dial the shaft 14 is returned counterclockwise and the arms 15 pick up lugs 17 on the intermediate wheels so restoring them and transferring their settings to the adjacent higher rings 1, 1<SP>1</SP> &c.

Title: Tube compression coupling
IPC: F16L19/10
Filed: 1980-07-24
Abstract: A tube compression coupling comprising a coupling body 1, a first ferrule 8, a second ferrule 15, an O-ring 19 and a retaining member 13. The inner ferrule 8 is a compressible ferrule which forms a seal with the tube 3 whilst the outer ferrule 15 forms seals with the inner ferrule 8 and with the coupling body 1 by means of a 60 DEG cone 18 and corresponding seat 7 in the coupling body 1. The two ferrules 8, 15, together with the tube 3 and coupling body 1 form an annular space wherein the O- ring 19 is retained in sealing contact with the tube 3 and the coupling body 1 by the ferrules 8, 15 without the O-ring 19 being damaged on the tightening of the compression coupling by tightening retaining member 13 which is in threaded engagement with coupling body 1. This enables an O-ring 19 to be used in a compression coupling in such a way that it only experiences a pre-determined amount of deformation to provide a seal. <IMAGE>
