Abstract: 1328957 Foamed polyamides STAMICARBON NV 19 Jan 1971 [21 Jan 1970] 2599/71 Heading C3C Polyamide foam is made by anionically polymerizing one or more molten lactams in the presence of a blowing agent, one or more foam stabilizers and one or more finely divided, porous materials. The porous materials have open cell structures and absorb the blowing agent more readily than the lactam. The blowing agent is usually a low-boiling aromatic or aliphatic hydrocarbon, for example, petroleum ether. Compounds used as foam stabilizers include organosiloxanes, organopolysiloxanes and organosiloxane oxyalkylene block copolymers. The stabilizers are preferably present in a proportion of 0À5 to 1À5% of the weight of the monomer. Suitable porous substances specified are expanded vermiculite, expanded perlite, urea formaldehyde and phenol formaldehyde foams and various proprietary gas-chromatography carriers. The polymerization of caprolactam is exemplified, the polymerization being carried out conventionally starting with lactam-N-anions, in particular sodium caprolactam. Promoters may be present, e.g. tribenzamide and hexamethylene diisocyanate.

Title: Digital-to-analog converter
IPC: E02D27/26
Filed: 1962-01-26
Abstract: 924,314. Digital to analogue converters. GENERAL ELECTRIC CO. Jan. 26, 1962 [Feb. 28, 1961], No. 3117/62. Class 40 (1). A digital to analogue converter comprises a number of relay circuits each of which is such that one contact provides both a holding current for the relay and an analogue current. Serial data signals are passed to a register 10 and are read out in parallel by AND gates 17-20 controlled by a timing pulse: relays K1-K4 are thereby set to represent the signal. Meanwhile, new data signals can be passed to the register, gates 17-20 being blocked. Contacts K1a- K4a select one or other of two voltages, dependent on the corresponding data bit, which voltage is passed to one or other of two converter units C11-C12, selection being by way of relays K11, K12. Each section of a converter unit, e.g. section 41, comprises a circuit including relay K41. If K1 is energized momentarilyindicating a "0"-K41 is earthed and is energized, whereby contact K41a reverses and holds the relay K41 energized. Resistor 45 is weighted so that a current proportional to the data bit passes to a summing amplifier when K41 is not energized, the analogue signal then appearing at 55. If now relay K1 is de-energized, representing a " 1," relay K41 is shorted and contact K41a connects resistor 46 in circuit thereby to apply a weighted current to the output.
