Title: Improvements in or relating to the manufacture of copolymers
IPC: C08F30/02
Filed: 1949-12-29
Abstract: Copolymers, which are resistant to inflammation and sparingly soluble in organic solvents, are made by copolymerizing vinyl acetate with triallyl phosphate in the presence of a catalyst, e.g. a peroxide or persulphate.  The process may be effected in bulk in a sealed vessel at temperatures of 40-100 DEG  C.; by refluxing in aqueous dispersion; or in solution, e.g. in methanol. Monomer mixtures containing 2-40 per cent of triallyl phosphate yield hard, tough, clear resins which are not easily burnt or are self-extinguishing after ignition.  With more than 40 per cent of triallyl phosphate, the products are jelly-like and strongly resistant to fire.  Benzoyl peroxide and potassium persulphate are specified catalysts and dispersion ingredients include the sodium salt of maleic anhydride-styrene copolymer, ethyl acetate and polyvinyl alcohol. The resins may be moulded and machined.

Title: Bistable trigger stages
IPC: H03K3/356
Filed: 1974-07-30
Abstract: 1482114 Transistor bi-stable circuits SIEMENS AG 30 July 1974 [2 Aug 1973] 33529/74 Heading H3T A bi-stable circuit comprising a pair of cross coupled field effect transistors 1, 2 with load elements 3, 4 and switching elements 5, 6 in the cross-coupling paths is characterized in that each load element is shunted by respective MNOS transistors 8, 9, the gate electrodes of which are coupled to a common control input 16. The MNOS transistors store the state of the bi-stable when the power supply at 13, 14 is disconnected. Assume the bi-stable is in the state in which transistor 1 is conducting making point 11 0 volts, and transistor 2 is non-conducting making point 12 U volts (approximately the supply voltage at 13). If it is desired to switch off the supply, switches 5, 6 are first opened, and a large negative pulse is applied to input 16. Since the full voltage U exists across transistor 8, the negative pulse will switch the threshold value of this transistor to a higher level, but will not affect that of transistor 9, across which no voltage exists. The power supply may now be disconnected. To reset the bistable to its previous state on resumption of the power supply, a small read out pulse is applied to input 16 which is sufficient to switch on transistor 9, but not sufficient to overcome the higher threshold level of transistor 8. The full supply voltage at 13 is thus applied via transistors 9, 6 to the gate of transistor 1 so that this transistor becomes conductive as before. To reset transistor 8 to its low threshold level a large positive pulse is applied to input 16. This does not affect the state of the bi-stable circuit as it turns both transistors 8, 9 off.

Filed: 1948-12-30
Abstract: 680,204. Making card-clothing. SCHAUB, A. H. Dec. 30, 1948 [Jan. 3, 1948; Jan. 3, 1948], Nos. 33536/48 and 33537/48. Class 120(iii) A card setting machine, of the type in which wire staples are first formed and then inserted into the foundation material of the card clothing, is characterized in that the parts for forming the staples are supported by a single common movable member. As shown, a slide 1, slidable in guides in the machine frame, carries bearings 7, 8 for a further slide 9 and a bearing 6 for a crowner 14. A bar 30 carrying needles 32, for piercing the cord clothing 2, is slidably pressed against the bottom of slide 1 by a spring 34. Pivoted to bearing 6 is a crown support 23 pressed down by a spring 27 on to a resilient plate 28 fixed to slide 9. Folders 14a, Fig. 2, are carried on arms 13 pivoted at 11 to a cross-member 10 carried by slide 9. In operation, from the position shown in Fig. 1, needle bar 30 is advanced by movement of an arm 48 to cause needles 32 to form two holes in the clothing 2; bar 30 is then retracted, engagement of a projection 49 theron with slide 1 causing it to swing downwards clear of crowner 14 and crown support 23 between which a cord wire (not shown) is fed. Slide 9 and folders 14a are now advanced by the action of a lever 46, crowner 14 also being advanced under the pressure of a spring 18 to grip the wire against support 14. A knife cuts off the wire, and continued forward movement of folders 14a causes the wire ends to be bent forward rather more than 90 degrees, folders 14a being rocked inwards slightly by engagement of abutments 52, on bars 13, with projections 53 on bearing 8; as the folders advance further they return to their normal spacing and the wire legs spring back at right angles to the crown of the staple so formed. Slide 1 is now advanced by the action of a lever 40. so that support 23 and crowner 14 spring- pressed thereagainst are advanced to insert the staple into the holes formed in clothing 2, As slide 9 and folders 14a are retracted, plate 28 is also withdrawn and a projection 29 thereon raises support 23 out of enagement with the staple; thereupon slide 1 and crowner 14 are also returned to their initial positions, and needle bar 30, which has meanwhile moved forwardly, swingsupwardly to its original position.
