Title: Improvement in nut cracking machines
IPC: A23N5/00
Filed: 1922-01-03
Abstract: 191,948. Coari, F. A. Jan. 3, 1922. Cracking nuts.-In a machine for cracking nuts, the nuts are contained in a hopper 4, Figs. 2 and 3, and are carried upwards by a conveyer 7 comprising parallel transverse bars 10 provided with pockets 12. Ejector pins 23, Fig. 2, enter bores 18, Fig. 27, in the pockets 12 and transfer the nuts to pockets 22 in a conveyer 19 which transfers the nuts intermittently towards cracking mechanism contained in a housing 21, Figs. 3 and 18. Plungers 45 are supported on a raised portion 44 of the housing, and engage vertically sliding wedge members 51. Each wedge is provided with an inclined groove 52 engaged by the rear end of a plunger, and a tipping bar 58 roughened at 59. The wedges are raised simultaneously by brackets 60 on cam-operated yokes 61, a number of nuts are fed into position between the plungers 45 and the wedges are allowed to drop until they force the plungers to engage the nuts. The wedges, at this stage, may be at different heights, according to the size of the corresponding nut. Cross-heads 53 are then advanced towards each other and impart sufficient pressure to crack the nuts. The portion of the conveyer which is nearest the plungers is withdrawn from the nuts during the cracking operation by a camoperated arm 89, 91 which actuates a cross-head 88 carrying the conveyer chain at this part of its travel.

Title: Anthraquinone dyestuffs
IPC: C09B1/38
Filed: 1973-01-02
Abstract: 1395088 Anthraquinone dyestuffs BAYER AG 2 Jan 1973 [3 Jan 1972] 204/73 Heading C4P Novel dyestuffs of the formula  (wherein R and R 1  are different and are optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl, aryl or heterocyclic radicals; one X is NO 2  or optionally substituted NH 2  and the other is H; A is a direct bond or -O-, with -OSO 3 H being bonded to a C atom of R, R 1  or X and -SO 3 H being bonded to a C atom of an aromatic-carbocyclic ring in X, R or R 1 ; and n is 1, 2, 3 or 4) are prepared by direct sulphonation of corresponding compounds not containing -OSO 3 H or -SO 3 H groups. Thus aromatic rings are sulphonated and alcoholic OH groups are converted into sulphuric acid half-esters; the latter may subsequently be saponified to free OH groups again when it is desired that the product shall only contain SO 3 H and not OSO 3 H groups. In the products NO 2  groups may be reduced to NH 2  groups; the latter may be substituted; NH acyl groups may be saponified; sulphonic acid groups may be converted via sulphohalides to sulphonamide groups; the dyestuffs may be halogenated; and positively substituted aryl radicals in the dyestuffs may be reacted with compounds which carry a reactive methylene group, e.g. N-methylol derivatives of various compounds, particularly of caprolactam. The novel dyestuffs may contain fibre-reactive groups. Starting materials of the formula which are also dyestuffs are prepared from amines NH 2 R 1  and compounds of the formula (wherein G is a replaceable substituent, e.g. a halogen atom) which are in turn prepared (a) by reacting 1,5- and 1,8-dinitroanthraquinones with amines NH 2 R to give compounds of the formula (in which one D is NO 2  and the other is H) and then for example halogenating these to give the corresponding 4-halo compounds and optionally reducing these to the corresponding 5- or 8- amino compounds which may subsequently be acylated or reacting them with NH 2 R 2  (wherein R 2  is optionally substituted alkyl, cycloalkyl or aralkyl) to give 1-NHR-4-halo-5- or 8-NHR 2 - anthraquinones or with arylamines to give 1-NHR-4-arylamino-5- or 8-nitro-anthraquinones which may subsequently be reacted with amines Z 2 H (wherein Z 2  is an optionally substituted alkyl-, aralkyl-, aryl- or heterocycloamino radical) to give 1-NHR-4-arylamino-5- or 8-Z 2 -anthraquinones or reduced to 1-NHR-4- arylamino-5- or 8-amino-anthraquinones; or (b) by replacing one halogen in a 1,4-dihalo-5(8)-X- anthraquinone with -NHR using NH 2 R, a mixture of 2 isomers generally being obtained. The compounds (IX) wherein one X is NO 2  may also be reduced to the corresponding 1-NHR-4- NHR 1 -5- or 8-amino-anthraquinones; and the compounds (IX) wherein one X is NH acyl may be saponified to give the same products, in which the NH 2  group may subsequently be substituted. The dyestuffs may be used for dyeing and printing natural and synthetic polyamide materials, and, where they contain fibre-reactive groups, also for dyeing and printing natural and regenerated cellulose fibres. Specification 1,147,110 is referred to.

Filed: 1968-01-04
Abstract: 1,190,668. Selective printing. G. RITZERFELD. 4 Jan., 1968 [6-Jan., 1967], No. 574/68. Heading B6F. [Also in Division B4] In a printing or punching device operated by a typewriter to produce a record in binary code corresponding to characters printed by the type-. writer, stamps or punches 44 are selectively operated through respective rods such as 59, 28, 29, 30 by a common impression bar 42, the rods corresponding to selected stamps or punches 44 being released by electromagnets such as 20-23 and permitted to move into contact with a rod 27 under the action of springs 60, 31, 32, 33, so that cut-out portions (41), Fig. 3 (not shown), in the rods 59 &c., are displaced from a position below the bar 42, thereby permitting the bar 42 to engage the upper edge of a rod and to push it downwardly to engage and operate the stamp or punch 44. Alternatively, the cut-out portions may be displaced from the position below the bar 42 in the initial position of the rods 59 &c., and energization of an electromagnet may move a cut-out portion into such position. In a modification, the electromagnets (102), Fig. 5 (not shown), coact with substantially T-shaped members (101) which, when released swing due to springs (104) and locate rods (106) between an impression bar (114) and the stamps or punches (118). Combination type-setting, mechanisms; printing marks representative of alphanumeric characters. -The rods 59 &c are arranged across the apparatus in twenty groups of four, each group producing a record in binary code corresponding to a typed character. On depression of a typewriter key, the keyboard is temporarily locked by a magnet (154), Fig. 6 (not shown), and the corresponding electromagnets of a first group are energized, so that requisite rods 59 &c. are set. The keyboard is then unlocked if the setting is correct so that a second character may be typed and corresponding rods 59 &c. of a second group set. The characters are coded by an electrical circuit (Fig. 6). An incorrectly set group may be reset by activating a magnet such as 90 which restores the group of rods to their initial position through links 95, 94 and a bar 97. Power operation.-When a complete line of rods 59 &c. has been set, a motor 34 is switched on for one cycle, or the motor may be continuously cycling and a one-revolution clutch (not shown) operated, to rotate a shaft 35 on which two crank wheels 39, 40 are mounted. Each crank wheel 39, 40 carries a crank arm 37, 38 connected to the bar 42 so that rotation of the shaft 35 moves the bar 42 downwardly to effect an impression through the rods 59 &c. Line spacing.-Rotation of the shaft 35 effects resetting of the rods 59 &c. through rotation of cams 50, 51 by gears 47, 48, the cams 50, 51 displacing links 52, 53 connected to bars 57, 58 attached to the rod 27. Line spacing is effected by such displacement of the bars 57, 58 through pawls 71, 72 coacting with ratchets 73, 74 which are mounted coaxially with pin-wheels 75, 76.
