Patent GB-1173367-A (GB)
Title: Data Store
Inventor: GARDNER PETER ALAN EDWARD
IPC: G11C8/16
Filed: 1967-05-11
Abstract: 1,173,367. Circuits employing bi-stable magrietic elements; transistor bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORP. 11 May, 1967, No. 21920/67. Headings H3B and H3T. [Also in Division G4] A matrix store having bi-stable data storage elements coupled between word lines and sense lines is such that a signal on a sense line produced by interrogation of an element can be used to set any further element coupled to the same sense line and conditioned to respond, and when an element is so conditioned the propagation of the signal to elements further along the sense line is inhibited. Fig. 3 shows a single storage element at the intersection of a word line and a complementary pair of bit/sense lines. One of transistors T1, T2 is conducting to store a bit. For reading, the word line potential is raised, thus cutting-off that one of the transistors T3 corresponding to the conducting transistor T1 or T2, producing a pulse on the corresponding bit/sense line at the top of Fig. 3. For writing, a pulse is applied to that one of the bit/sense lines at the bottom of Fig. 3 corresponding to the complement of the bit value to be written, and the potential on the word line is lowered then raised to normal again. The pulse on the bit/sense line causes the corresponding transistor T4 to conduct. The transistor T1 or T2 corresponding to the other transistor T4 will conduct when the word line potential returns to normal. The lowering of the word line potential prevents the pulse arriving on one of the incoming bit/sense lines (bottom of Fig. 3) from passing along the outgoing bit/sense lines (top of Fig. 3), by disabling the transistors T3. Accordingly a word can be written either from external bit drivers or from another word position in the matrix, and the passage prevention feature of the previous sentence enables a plurality of words to be transferred simultaneously. A modification straightforwardly omits one of the pair of sense lines and the associated transistors T3, T4 &c. Transferring a word in true rather than complement form is also mentioned. Thin magnetic film stores are mentioned. Specification 1,119,357 is referred to for alternative storage elements.

Abstract: 1304715 Treating films DOW CHEMICAL CO 8 May 1970 [2 June 1969] 22416/70 Heading B5B [Also in Divisions C3 and D1] Process for the surface sulphonation of a polymer film or web comprises subjecting at least one of the surfaces of the film in a dry atmosphere to a flowing sheet of dry, gaseous sulphur trioxide substantially across one dimension of the film surface while moving the film or the sheet of gas at a substantially constant rate perpendicularly to each other. Preferably, the film is dried before treatment by a blast of dry inert gas, a similar blast being used after the sulphonation to remove excess SO 3 . The sulphonated film may be treated with a fluid neutralization agent, suitably gaseous ammonia, methylamine, dimethylamine or ethylamine, and/or additionally with aqueous solutions of metal salts, for example salts of Ag, Ni, Cd, Zn, Mg or Ba. Polystyrene and polyethylene films are mentioned. Apparatus suitable for the process of the invention comprises a substantially closed sulphonation chamber 10 through which a polymer film 25 is fed over idler rollers 20 from feed roller 24. The chamber 10 is divided into a series of compartments by vertical baffles 12, horizontal baffle 16 together with the baffles 12 on either side defining the sulphonation zone 46. Prior to entry into the zone 46 the film is blasted outside the chamber with dry inert gas by scrubbers 221 and further dried inside the chamber 10 by inert gas scrubbers 222. It is sulphonated by passage between sulphur trioxide scrubbers 241, and scrubbers 223 blast dry inert gas on to the film after it has been sulphonated to remove excess SO 3 . Tubular exhausts 231, 242 and 232 exhaust the excess inert gas and any excess SO 3  out of the chamber 10. The sulphonated film then passes through neutralizing chamber 18 where it is alternately blasted with the same inert gas through scrubbers 224 (outside chamber) and 225 and ammonia gas through scrubbers 251. The chamber 18 is also provided with tubular exhausts 233 and 252. The treated film is then washed in water bath 28, blown free of water by air knives 30, dried in oven 32 and wound on take-up roller 26. Dry sulphur trioxide gas is supplied to the chamber 10 from tanks 38, it is usually diluted with an inert gas supplied from tank 58. Dry ammonia or other neutralizing gas is supplied from tanks 50. The apparatus may be modified so that the film is sulphonated and neutralized only (Fig. 2, not shown), sulphonated only (Fig. 4, not shown), sulphonated and washed only (Fig. 5, not shown), sulphonated, dipped in an aqueous bath containing a metal salt solution and washed (Fig. 6, not shown), or so that the film is contacted with gaseous SO 3  while travelling horizontally between a series of baffle boxes (Figs. 7-11, not shown).

Title: Method for measuring nitrogen oxides in pollution air and device for performing the same method
IPC: G01N33/00
Filed: 1973-05-14
Abstract: 1366235 EPR measurement of nitrogen oxides SAGAMI CHEMICAL RESEARCH CENTER 14 May 1973 [18 May 1972 13 Sept 1972 (2)] 22861/73 Heading G1N Nitrogen oxides in a gas sample e.g. polluted air, are measured by an EPR spectroscope. NO 2  measurements are made with the sample at atmospheric pressure under Zeeman modulation, while NO is measured at low pressure, e.g. 0À1 torr, with Stark modulation. If only small amounts of oxide are present they may be concentrated by cold adsorbing them, e.g. on to P 2 O 5 . The measurements are preferably made in a C band  TE OIN  cavity, though an X band cavity can be used with a loss of sensitivity. The basic resonance cavity is shown in Fig. 7 at 20A, and is provided with gold Stark electrodes 53 and Zeeman coils 55. When the sample has been introduced into the cavity it is irradiated with constant frequency micro-waves and the field of electromagnet M is swept. When resonance occurs the impedance of the cavity changes and this is detected by a micro-wave bridge, one arm of which contains the cavity. The bridge output is compared with the 100KHz signal applied to the Stark or Zeeman modulators and the resulting signal is recorded. When a high concentration of NO 2  is being measured a sample tube containing the gas may be inserted directly into the cavity. Alternatively when a high concentration of both NO and NO 2  is measured a small part of the sample is first allowed to enter the evacuated cavity and the NO is measured by Stark modulation at the resulting low pressure, then the rest of the sample and pure air are admitted to the cavity and the NO 2  is measured by Zeeman modulation at the resulting atmospheric pressure, Fig. 1 (not shown). When low oxide concentrations are measured the sample 10', Fig. 2, is flowed over a cold adsorber 18 by a pump 13 prior to release into the cavity. In Fig. 2 polluted air is passed over the adsorber for, say, 15 minutes, while the adsorber is cooled by air from a blower which passes through cooler 30; the adsorber may thus be maintained anywhere between normal and liquid oxygen temperatures. After adsorbtion the blower is connected to heater 32 and the oxides are driven from the adsorber and enter the evacuated resonator 20A. If the cooling temperature is very low the NO will be oxidized by air and can then be detected as NO 2 .
