Title: Apparatus for handling and transferring articles
IPC: B21D43/20
Filed: 1975-01-28
Abstract: 1453487 Rotary and reciprocating conveyers MONARK-CRESCENT AB 28 Jan 1975 3696/75 Heading B8A Articles 3 ejected from a press tool (1) (Fig. 1, not shown) are picked up from a position (3<SP>11</SP>) by a pneumatic gripper 4 on an arm 6 which carries the article and releases it at a position 3<SP>111</SP> on a disc 9. This is arranged to move in synchronism with a control disc 10 having position marks 11 which are sensed by a member 14. The latter is connected with a control unit 16, to which control cylinders 7 and 8 of the arm 6 are also connected. In this way, an article is placed successively in a circular series of positions 3<SP>111</SP> on the disc 9, corresponding to the marks 11. A further sensor 13 cooperates with indicia on the periphery of the disc 9 and after one complete revolution of the latter the discs 9 and 10 are moved radially in synchronism, and another circular series of articles is positioned on the disc 9. When the disc 9 is completely filled with articles, it may be stepped downwards, and a stack of articles may be placed on top of the original layer. The discs 9 and 11 may be other than of circular shape. In this case, the radial movement may be replaced by movements parallel with coordinate axes. All the movement of the apparatus are controlled by programming means.

Title: Process for the production of substituted 5-aminopyrazoles
IPC: C07D231/38
Filed: 1959-02-04
Abstract: Substituted 5-aminopyrazoles are prepared by reacting 1-cyanopropadi-1,2-ene or a substituted 1-cyanopropadi-1,2-ene with hydrazine, a monosubstituted hydrazine or a compound containing two -NH-NH2 groups.  Suitable substituted cyanopropadienes include 3-alkyl- and 3-alkanol-1-cyanopropadi-1,2-enes.  Instead of the pure cyanopropadienes, mixtures with the isomeric alkynenes such as are formed by reacting 1-halogeno-prop-2-ynes, which may be substituted, with hydrogen cyanide in the presence of a cuprous catalyst. 1-cyano-propadi-1,2-ene prepared by this method may contain 1-cyano-2-chloroprop-2-ene which will react with the hydrazine in the same way as the cyanopropadiene.  The hydrazine compound may have the formula R1-NHNH2 wherein R1 is hydrogen, an S-dioxo-1-thia-cyclopentyl-(3) radical, a C1-6 alkyl radical or an aryl radical or a hydroxy, cyano, carboxy, sulpho or nitro substitution product of any such radical. Generally approximately equivalent quantities of reactants are used.  A solvent may be used. Temperatures of 0-100 DEG C. are mentioned.  A mineral acid may be present.  The products may be used in the manufacture of dyes (see for example Specification 802,097).  Compounds prepared in examples are; (1) 1-phenyl-3-methyl-5-aminopyrazole; (2) 1-(31-sulphophenyl)-3-methyl-5-aminopyrazole; (3) 1-(b -cyanoethyl)-3-methyl-5-aminopyrazole; (4) 1-(41-carboxyphenyl)-3-methyl-5-aminopyrazole; (5) 1-(b -hydroxyethyl)-3-methyl-5-aminopyrazole; (6) 1-(81-sulphonaphthyl-(11)-3-methyl-5-aminopyrazole; (7) 4, 41-bis-(511-amino-311-methylpyrazolyl-(111) )-stilbene-2,21-disulphonic acid; (8) 1-phenyl-3-(but-3-en-1-yl)-5-aminopyrazole; (9) 1-(3-sulphonamidophenyl)-3-methyl-5-aminopyrazole; (10) 1-(4-sulphonamidophenyl)-3-methyl-5-aminopyrazole; (11) 1-(3-chlorophenyl)-3-methyl-5-aminopyrazole; (12) 3-methyl-5-aminopyrazole; (13) 1-(1-cyanoprop-1-en-2-yl)-3-methyl-5-aminopyrazole; (14) 1-(benzthiazolyl-2)-3-methyl-5-aminopyrazole; (15) 1-phenyl-3-methyl-5-aminopyrazole and (16) 1-(1111-dioxo-11-thiacyclopentyl-(31)) -methyl-5-amino-pyrazole. Starting materials prepared are 1-cyano-propadi-1, 2-ene, containing 1-cyano-2-chloro-prop-2-ene which may be separated by distillation, by the action of HCN on 1-chloro-prop-2-yne in the presence of cuprous chloride and copper powder and 1-cyanohexatri-1,2,5-ene containing 1-cyano-5-en-2-yne and 1-cyano-1,3,5-ene similarly from hex-5-en-2-yl chloride; the 1-cyanohex-5-en-2-yne may be isomerised to 1-cyanohexatri-1,2,5-ene by means of a weakly alkaline agent, e.g. sodium phenate.  Cyanacetone phenylhydrazone is isolated as an intermediate product in Example 1 from phenyl hydrazine and 1-cyano-propadi-1,2-ene.

Abstract: 875,897. Animal feeding pens. KIDDERMINSTER STEEL Ltd. Jan. 12, 1960 [Feb. 6, 1959], No. 4217/59. Class 5(2). [Also in Group XXV] A pig feeding pen, designed to permit a pig to feed without being savaged by other pigs, comprises a gate so constructed, and so mounted on the frame 16 of the pen that it can initially be opened by a pig outside the pen, closes when the pig is inside the pen, and is automatically locked in its closed position so that it can only be opened by the pig backing out of the pen. The gate is hinged to a cross member 19 of the frame, and comprises two parts 21 and 25 hinged together at 24, the relative movement of the two parts being controlled by a stop 31. The lower part 25 of the gate comprises a cross member 28 fitted with rollers 32, the ends of the cross member engaging with latches 33 pivoted on brackets 35 fixed to the frame of the pen. The gate normally occupies the position illustrated in Fig. 3, when a pig can gain access to the pen by pushing upwards on the rollers 32, causing the two parts of the gate to pivot in jack knife fashion about the pivot 24. When the pig has entered the pen, the gate falls towards its normal position, striking the arms 37 of the latches 33, the latter pivoting to allow the ends of the member 28 to rest on the brackets 35 as shown in Fig. 5. The gate cannot then be opened from outside the pen, but can be swung rearwardly about the frame member 19 by the pig inside the pen and when this happens the gate swings back into the original position shown in Fig. 3.
