Title: Automatic release for photographic lens shutters
IPC: G03B9/58
Filed: 1931-06-15
Abstract: 372,131. Photographic shutters. MORAT, F., Eisenbach, Schwarzwald, Germany. June 15, 1931, No. 17352. Convention date, June 14, 1930. [Class 98 (i).] An automatic device in which the wire release is embraced by a stationary cup and a longitudinally movable gripper arm which is moved by clockwork to actuate the wire release and then disengaged from the driving mechanism and jerked back by the spring of the wire release to terminate the exposure, is characterized in that the operating bar for the gripper is held in the inoperative position, although acted upon by the clockwork, by a brake which is so slowly disengaged by the clockwork that the braking is only completely removed after the operating bar has commenced to move. As shown, the wire release 2 is held in the cup 4 by the gripper 3, which has a nose 5 engaging a notch in the bar 6. The bar 6 has a pin 9 and an elongated slot 8 co-operating respectively with a fixed slot and a pin 10, and is pulled down to its lowermost position by the winding of the driving spring. It is pushed upwards and held in the position shown by the spring 15 and the cam 12, which is rotated in a clockwise direction by the spring 24. On releasing the mechanism, the shutter is not operated until the pin 22 strikes a notch in the bar 16 to rotate the cam 12 in an anticlockwise direction, and allow the bar 6 to accelerate slowly. When the adjusted exposure time has expired a cam on the winding disc disengages the nose 5 from the bar 2 and permits the shutter to close. The bar 6 is then slowly decelerated by the co-operation of the surface 18 with the spring 15 and the cam 12.

Title: Method of casting metals
IPC: B22C9/08
Filed: 1951-07-24
Abstract: 690,790. Moulds. NIELSEN, F. July 24, 1951, No. 17541/51. Class 83 (i). In casting light or other metal the passage from bottom of the inlet header E to the actual gate A adjoining the mould cavity C is formed so that kinetic energy is reduced by deflections &c. and the cross-section is increased in stages to correspond so that the total energy of the metal entering the cavity C does not exceed a predetermined value. The deflections may be 90 degrees between horizontal portions I, II, III and IV, Figs. 1 and 2, and the successive increases in cross-section 60 per cent theoretically or as low as 33 per cent in actual practice. Increases in cross-section may be accompanied by decreases in height as in Fig. 3, which shows a single gate. The stages need not be all equal as shown. Successive passages may each be connected to the preceeding one shortly before its end as in Figs. 5 and 6. One or more passages I ... IV may extend upwardly as at S, Fig. 5, to collect slag. For ingot or other moulds with a vertical division, alternate passages as II, Fig. 7, may be for upward flow. This Figure also shows branched passages leading to four gates Al, A2, B1, B2 for four cavities C or one large cavity, the passages IIIa and IIIb being reduced in cross-section after the gates A1 and B1. The pressure in passages after branching may be equalized by a connect. ing passage. Distribution channels after the last deflection and which are vertical or steeply inclined preferably have cross-sections greater than normal. If there are a number of gates, one above the other, so that they come into action successively, their total cross-section may be greater than the normal. All the non- vertical passages may with advantage be inclined slightly for upward flow. The moulds shown are " bottom poured " but the invention may be applied to top pouring and pressure casting.

Filed: 1957-06-03
Abstract: The invention comprises chromium complexes of dyestuffs, free from sulphonic acid groups, of formula:  <FORM:0844398/IV (c)/1> where R is a substituent which does not hinder the diazotisation of the primary amino group and the coupling of the diazonium compound with the pyrazolone derivative or the formation of the chromium complex by way of the carboxyl group, B is the residue of a 5-pyrazolone which may be alkyl or aryl substituted in position 1 and residue A may be further substituted.  The dyestuffs are made by conventional methods in which the appropriate diazotised aniline and pyrazolone are coupled and the product chromed. Advantageously 1, 2-complexes are obtained.  Indicated as values for R are halogen atoms, alkyl, aralkyl and aryl groups, trifluoromethyl and cyano groups, alkyl-, aralkyl- and aryl-ether, -thioether and sulphonyl groups, alkyl- or arylketo groups, dialkyl- and acyl-alkyl amino groups, alkyl-, cycloalkyl- and arylsulphoxide groups and N-substituted sulphonamide groups. Preferred values for R are halogen atoms and alkyl groups e.g. chlorine, methyl and ethyl groups.  Indicated as further substituents are halogen atoms, alkyl, alkoxy, nitro, hydroxy, acylamino, alkyl- or aryl-sulphonyl, acyl, carboxylic acid amide or arylamide groups and sulphonamide and N-substituted sulphonamide groups.  Chiefly 3-alkyl-5- pyrazolones, optionally substituted in the 1-position especially 3-methyl-5-pyrazolones are used.  Mixed chromium complexes may also be obtained in which in the final product the chromium atom is combined with a molecule of an aniline-pyrazolone dyestuff indicated above and with a molecule of another complex, former having no sulphonic acid groups such as an #s, #s1-dihydroxy- or #s-hydroxy, #s1-carboxy-azo dyestuff or an uncoloured compound such as an aryl #s-hydroxy-carboxylic acid.  The mixed complexes are made by usual methods.  The products dye natural and synthetic polypeptide fibres, especially wool, silk, polyamide and polyurethane fibres and leather giving greenish-yellow shades. Textiles are dyed with the alkali metal or ammonium salts of the dyestuffs.  Some of the dyestuffs may be used for dyeing nitro or acetyl cellulose lacquers and acetyl cellulose spinning masses. In examples illustrative of the preparation of the dyestuffs and their use in dyeing wool and polyamide fibres the diazo components used are 3-methyl-, -ethyl-, -methanesulphonyl- and -chloro-, 3, 5-dimethyl-, -dichloro- and -dibromo, 3-methoxy -6- chloro- and 3-chloro -5- ethyl- 2-aminobenzene-1-carboxylic acids and the coupling components are 1-methyl-, -(a -phenethyl)-, -butyl-, -benzyl-, -phenyl-, -(21-chloro- and -ethyl-, 31-sulphamido- and -chloro- and 41-methyl-, -methoxy- and -ethoxy-phenyl)-3-methyl -5- pyrazolones and 3-methyl -5- pyrazolone.  Specification 820,502 is referred to.  Reference has been directed by the Comptroller to Specifications 692,073, 797,046 and 798,746.

Abstract: 949,003. Riveted joints. TOWNSEND CO. May 8, 1962 [May 12, 1961], No. 17679/62. Heading B3U. [Also in Division F2] In a blind rivet assembly comprising a tubular rivet with a shank 1 and bore 6 which is inserted through holes 2 in plates 3, the rivet head 4 abuts the accessible side of the plates and the tail 5 projects through to the blind side. A mandrel 7 with head 8 on the blind side extends through the bore of the tubular rivet with the head 8 adjacent the tail 5 of the shank 1. The mandrel head has a frustoconical portion 9 and a flat face 11 parallel with the mandrel axis. The completed assembly is formed by applying pressure, by means of a known riveting device, to hold the head 4 against the accessible side of the plates and exert a pulling force on the mandrel 7 to pull the head 8 into the tail 5 of the tubular shank. This action produces spreading of the tail of the tubular shank which as it bears against the axially flat face 11 of the mandrel head is drawn around this face so as to form a retaining lip 13. The mandrel shank is adapted by means of groove 14 to break off in line with the rivet head 4 when the assembly is effectively formed. In another embodiment an alternative form of mandrel head is shown resulting in a larger overlap of the lip to produce a firmer grip when the joint is formed.
