Abstract: 1491050 Making olefin polymer fibrids BASF AG 19 Dec 1974 [21 Dec 1973] 54855/74 Addition to 1477378 Heading C3P Olefin polymer fibrids are made by dissolving an olefin polymer in an organic solvent under pressure and at a temperature which is above the boiling point of the solvent at standard pressure, and flashing the solution by passing it through an orifice into a space which is at a lower pressure and in which shearing forces act on the solution during flashing, the solvent used being pentane or a mixed solvent containing sufficient pentane to cause the polymer to separate as discrete fibrids during flashing and the shearing forces being produced either by flashing the polymer solution through one orifice of a two component nozzle, whilst a driving jet of an auxiliary medium is passed through the other orifice, on by means of a high-speed stirrer which is placed in the space into which the solution is flashed. Preferred solvents are naphtha cuts containing 5-50 wt. per cent pentane, and n-pentane/isopentane mixtures. The concentration of the original solution may be 10-25 wt. per cent and the dissolution may be carried out at 100-180 C. and 10-20 atmospheres. The space into which flashing occurs may contain a non-solvent or precipitant for the polymer, which may be the same as that used to form the original solution (being a non-solvent at the lower pressure). The treatment of polyethylenes is exemplified.

Title: An electrical arrangement for use in a teaching machine
Inventor: MCKAY IAN GUY
IPC: G09B13/00
Filed: 1968-11-20
Abstract: 1285713 Teaching typing KEE Inc 13 Nov 1969 [20 Nov 1968] 55159/68 Heading B6F A machine for teaching typing comprises apparatus for verifying keyed information with the same information previously encoded on a storage means such as a punched tape. The switches 1 to 20 associated with each key of a keyboard encoder, are connected to a diode matrix 21. The output of the matric is connected via leads 23 to 28 to the operating coils 29 to 34 of a series of relays forming a comparator 35. The moving contacts 40 to 45 of the relays are connected via leads 47 to 52 to a punched tape reader or store 110. Coincidence or non-coincidence between the keyed imput and the punched tape imput is determined by reading the signals on a pair of leads 54 and 55 connected to the fixed contacts 58 to 69 of the relays. Coincidence results in the being advanced to the next code, and non- coincidence prevents this happening, until such time as a correction is made and key 100 is depressed for the error cancelling circuit 112. Leads 54 and 55 are connected via gates (91) and (93) to a gate and storage circuit (92, Fig. 2). A third lead 94 to the circuit 92 carries a control signal sent after a time delay. This time delay is necessary to enable the reed relays, which due to manufacturing tolerences are not identical, to be actuated before final comparison is made. The control signal is transmitted from a further signal relay having a coil 71, moving contact 72, and fixed contacts 73 and 74. The coil 71 is connected between zero volt line 36 and the - 12 volts line via the emitter-collector circuit of a transistor 75. The bore of the transistor is connected to the + 12 volts line 76, - 12 volts line 86 via a time delay circuit 84, 85, and to the output leads 23 to 28 of the diode matrix 21 via isolating diodes 78 to 83. In operation, if the conditions on the leads 54 and 55 are those corresponding to coincidence in the comparator 35, the gate circuit (92, Fig. 2) is opened by signals from the gates (91) and (93), and the control signal on lead (94) causes a signal to appear on lead 97 which advances the punched tape. Until such time as the signal relay is switched to supply a control signal on line 94, the moving contact 72 of the relay contacts fixed contact 73 thereby supplying a signal to the "incorrect" lead 54 so that the gate (91, Fig. 2) is held. Non-coincidence in the comparator 35 is indicated either by a signal on lead 54 or no signal on lead 55. This results in no signal on lead (97) and an error signal on lead (98) which prevents advance of the tape. A fourth lead 90 connects fixed contact 73 of the signal relay with the circuit (92). The imput of the circuit (92) includes a bistable buffer circuit (111), which isolates circuit (92) from interference from the reed relays of the comparator, and is reset by a signal on the line 90.
