Title: Analogue-to-digital converter
IPC: H03M1/00
Filed: 1971-04-19
Abstract: 1347105 Analogue to digital converters SOC DE FABRICATION D'INSTRUMENTS DE MESURE 19 April 1971 [21 Jan 1970] 21186/71 Heading G4H In an analogue to digital converter a succession of binary weighted voltages are each in turn either added to or subtracted from the unknown analogue voltage such that the cumulative algebraic sum tends towards zero, the binary coded number representing the unknown voltage being derived from the successive decisions to add or subtract the binary weighted voltages. In Fig. 1, an integrator 13, 14 first receives the unknown voltage through gate 11 for a time equal to one clock pulse and thereafter receives in succession binary weighted voltages, each for one clock pulse period, from resistors R1-R9 switched into the circuit by transistors T1-T9 operated in succession by a clocked register 1. Gate 7 passes these voltages directly, positively, and gate 8 passes them inverted, negatively. Logic 20 delivers signals S and #S to operate one of the gates according to whether comparator 16 indicated that the previous state of the cumulative sum was positive or negative. The binary coded output is delivered from gate 28. After 12 clock pulses H, two for control and 10 for each binary step, integrator 33 observing the absence of the train of clock pulses switches monostable 34 to reset the whole circuit. In another arrangement (Fig. 3, not shown) the unknown voltage can be of either polarity and a polarity bit is put in front of the binary coded number.

Title: Apparatus for heat-treating and packing a liquid
IPC: B65B9/06
Filed: 1974-05-15
Abstract: 1452703 Packaging in sachets ALFA LAVAL AB 15 May 1974 [21 May 1973] 21634/74 Heading B8C [Also in Divisions A2 F1 and F4] A liquid, for example milk, is packaged by enclosing it in a tube moving through a heating zone and pinching the tube containing the thus treated material along spaced transverse lines to form filled sachets. The tube is flattened to an elongated cross-section as it passes through the heating zone and the liquid is made to flow faster than the speed of the tube in that zone. In the embodiment of Fig. 1 a film 3 from roll 2 is introduced through rollers 4 into housing 1. Liquid 8 to be packaged is fed from pipe 7 into a trough formed by the film and the film sealed together at its upper edge by discs 5 to form a tube enclosing the material. The tube is fed by frictional engagement with belt 9 through heating equipment 12 (see Figs. 3, 4 and 5) (not shown) and exits from the housing through rolls 13 into a device (14) for forming transverse seals (15). Individual sachets are separated by cutters (see arrows 16). The liquid being packaged is forced through the tube at a speed greater than that of the tube by a pump 11 comprising a rotating cylindrical array of freely rotating rollers which co-operate successively with belt 9. The pumping action may be enhanced by applying an overpressure to the housing or by appropriately modifying the equipment 12 to apply peristaltic type pressure to the tube. In a second embodiment, see Fig. 6, liquid is introduced through pipe 49 to the inside of a freshly extruded tube 47 which is passed downwardly through a first air heating chamber 40, a second dwell chamber 41, and a third cooling chamber 42, to a sachet forming device 56, 57. The material flows by gravity, perhaps supplemented by an overpressure, through the tube and the tube is appropriately shaped by supporting members 54 perhaps of wire netting. In a variation of this embodiment the chamber 40 may be replaced by one in which the material is microwave heated.
