Abstract: 1,245,425. Wet-spun polyamide filaments. FARBWERKE HOECHST A.G. 21 Nov., 1968 [21 Nov., 1967], No. 55376/68. Heading B5B. [Also in Division C3] Filaments may be wet-spun from solutions obtained by the anionic polymerization of a non-N-substituted # lactam in a solvent which is a solution of 0À9 to 50 wt. per cent of a lithium halide, cyanide, thiocyanate, azide or cyanate in a neutral or weakly basic C 1-12  organic liquid containing at least 2 atoms from Group V or VI of the Periodic Table linked with one another directly or via carbon and a semi-polar or double bond at at least one of such atoms. Other polymers e.g. polycaprolactam or polyacrylonitrile may also be dissolved in the solutions. In examples homo- or copolymers are prepared from the following monomers: 4- methyl-, vinyl-, n-butyl- or phenyl-azetidinone; 4,4 - dimethyl azetidinone; 4 - methyl - 4 - npropyl azetidinone; azetidinone; a lactam of the formula and cis or trans-3,4-dimethyl azetidinone, using as solvent LiCl in dimethyl formamide, acetamide or sulphoxide, pyrrolidone, methyl pyrrolidone, phosphoric acid tris dimethylamide or glycol carbonate; LiBr in dimethyl acetamide or formamide; or LiI in dimethyl formamide. Polymers of R.V. between 5À1 and 9À9 (1% in H 2 SO 4  at 20 C.) are obtained. In examples, such spinning solutions are spun into a coagulating bath of dimethyl formamide and water, or of water and the resulting filaments drawn in water at 72 C. to 80 C. to a draw ratio of from 3À4:1 to 4À8:1, rewashed and dried.

A machine for applying insulation to a stator winding bar of an electric machine comprises a master form 1, Fig. 3, of the same configuration as the bar to be insulated, and a carriage 4 that moves along the master form 1. When the carriage 4 is moving along the straight portions of the master form 1 it is guided by spaced rollers 8 that engage in a guide slot running along said straight portions. The carriage 4 has two fixing rollers 11, one on each side of the master form 1, and when one of these rollers reaches a concave arc it acts as a pivot 12 about which the carriage 4 rotates to guide it around a curve in the master form 1, the aforesaid slot being absent over this curved extent so that the spaced rollers 8 are temporarily free from guidance. The carriage 4 carries a taping head through which the winding bar to be taped extends, the winding bar being mounted such that it is parallel with the master form 1. The carriage 4 is driven by a pinion 6 engaging a rack 7. The bar being taped is held by a plurality of holders that open automatically, Fig. 6 (not shown), to allow the taping head to pass.

Abstract: 1335400 Foundry plant BADISCHE MASCHINENFABRIK GmbH 10 Dec 1970 [11 Dec 1969] 58781/70 Heading B3F A foundry moulding plant comprises flaskcarrying cars 5 travelling over two co-extending superposed tracks 1, 8, the track ends being connected by car lifting and lowering devices 9, 10. Each car 5 comprises two zones, one zone carrying a mould 14 and the other zone being a U-shaped member 16 which receives and supports "mould packages" (i.e. a sand mould and casting stripped from its flask). A flask transporting line 4 is linked with the upper 1, of the superposed tracks by flask onloading 2, and offloading 3, stations. In the flask-transporting line 4 a double moulding machine 24 moulds drags 13 and copes 12. The drags 13 are turned at 77 and mated with the copes 12 at 25, later to be loaded on to the cars 5 at 2. A mould weight 18 (which has been lying on the U-shaped member 16) is transferred to the mould at 2 and casting effected at 19. The cast mould is lowered to the lower track 8 at 9 and travels leftwards along the track 8 to be raised to the upper track 1 at 10, thus allowing the casting to cool. At the offloading station 3 (see Fig. 3) a pusher 44 and weight-carrying grab 35 are lowered and both are moved leftwards to deposit a "mould package" 17 from the member 16 on to a shake-out grate 38 and place the weight 18 within the U-shaped member 16. A pusher 80 is lowered and it moves leftwards to push the cope 12 and drag 13 on to a roller conveyer 36 and from there to an extractor station 32. At the extractor 32 the flask is forced downwards by a yoke 49 and a pusher 22 (see Fig. 1) forces a "mould package" on to a swinging transfer device 39. The flask then passes to a clearing station 21 and separating station 23 from where drag and cope are returned to the moulding machine 24, while the "mould package" is swung by the device 39 and inserted into a U- shaped member 16 on a car 5 at a station 34.

Abstract: 1406699 Mechanical switches NATIONAL PRESTO INDUSTRIES Inc 29 Dec 1972 [22 Nov 1972] 59975/72 Heading H1N [Also in Division G4] A switching arrangement for use in a burglar alarm attached to a door (see also Division G4) comprises an actuator rod 54 movable by member 18 from a position where it contacts a plunger 64 of a switch 40 (see Fig. 4) for closing the latter switch to a second position where a hook end of the rod is releasably held by one of catches 72, 86 (see Fig. 6) for keeping the switch 40 open. The catches 72, 86 are associated with a tripping lever 14 for releasing the actuator 54 and closing the switch 40 when the lever 14 senses that the door has been opened. Thus when member 18 is depressed with the door open, a latch member 74 having the catch 86 is in a forward position and rod 54 engages with catch 72; when the door is then closed, the latch 74 moves backwards and rod 54 under the resilience of a leaf spring 68 engages with catch 86. When the door is reopened, latch 74 moves forwards and rod 54 is released. Fig. 6 indicates that in the above positions, further switch contacts 124-126 are made and broken.
