Patent GB-954544-A (GB)
Title: Improvements relating to data loggers
Inventor: CHURCHILL JOHN LESLIE WESTON
IPC: G08C15/08
Filed: 1959-09-22
Abstract: 954,544. Electric selective signalling systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 22,1960 [Sept. 22,1959; Dec. 24, 1959], Nos. 32264/59 and 43892/59. Heading G4H. A number of signal sources S 1 , S 2 , S 3  are normally connected across an associated reservoir condenser C 1 , C 2 , C 3 , these condensers being isolated from the associated signal source and connected to a central point in turn in order to supply the various signals in turn to the central point and at the same time overcome difficulties in matching the various sources to apparatus at the central point which arise from variations in earthing of the sources. The signals from sources S 1 -S 3  may represent pressure temperature or flow rate, for example, and variations in earthing of the sources may arise because the potential of some of the sources is floating while other sources are earthed on one side or the other, and other sources may have partial earths due to leakage. The apparatus at the central point may include an amplifier and an analogue-to-digital converter as part of a measurement or control system. Switching of the condensers C 1 -C 3  is performed by relays having contacts R1a, R1b, R2a, R2b and R3a, R3b. The time constants of circuits r 1 C 1 r 1 <SP>1</SP> and so on may be made fairly large so as to filter out spurious mains hum signals. The occurrence of an open circuit atone of the sources may be detected by connecting a potential source across the lines from the sources through high resistors, Fig. 4 (not shown), the additional source being normally shorted by the sources S1-S3 but applying an exceptionally high voltage to a capacitor C1-C3 if an open circuit occurs in'the associated source. An alternative method of scanning the sources is shown in Fig. 5 wherein nine sources S1-S9 are arranged in three groups S 1 , S 4 , S,; S 2 , S 5 , S 8 ; and S 3 , S 6 , S 9 . Each group has an associated capacitor C 1 , C 2  or C 3  which are each connected across one of the sources S1-S9 by switch R10, R11 or R12, the charges or voltages attained being applied in turn to the central point, and the capacitors C1-C3 being connected to the next source in its group through one of switches R1-R9 when switches R10, R11 and R12 revert to their normal position on the left-hand contacts. In either method of scanning the sources, spurious signals may reach the central point through resistive or capacitive leaks between the switch contacts X and Y or X and Z, Fig. 2. This may be overcome by including an additional contact in each of switches R1-R3 arranged to connect the righthand contacts R1a, R1b and so on to earth when the switch is in its normal position.

Patent GB-1085147-A (GB)
Title: Polyester preparation
Inventor: PORTER KENNETH
IPC: C08G63/78
Filed: 1965-07-29
Abstract: Film- or fibre-forming polyesters are made by polycondensing a glycol ester of a dicarboxylic acid or low molecular weight polymer thereof in the form of liquid droplets of diameter 0.5 to 1000 microns, the droplets being exposed to a relative motion in a chemically inert gaseous fluid.  The droplets may be allowed to fall freely through the gaseous fluid (e.g. in a vertical tower) or the gaseous fluid may be in the form of an upwardly moving stream.  The partial pressure of glycol in the gaseous fluid is kept at a low value, e.g. by contacting the gaseous fluid with a condensing surface or by purging a proportion of the gaseous fluid and replacing it by fresh gaseous fluid.  Specified glycol esters are the ethylene glycol ester of terephthalic or 1:2-diphenoxyethane-4:41-dicarboxylic acids (alone or in admixture with adipic or isophthalic acid).  An example describes the preparation of polyethylene terephthalate.

Patent GB-927289-A (GB)
Title: Improvements relating to permanent magnets
IPC: C22C28/00
Filed: 1959-09-25
Abstract: A permanent magnet has as a constituent a phase which has been produced by a thermal treatment and which contains at least 60% Mn with the remainder substantially Al, the phase having a tetragonal crystal structure with an axes ratio c/a of >1 and <2.  An example of this phase is that occurring in a binary Mn-Al alloy (Mn: Al atom ratio 5:4) and having the required structure with an axes ratio about 1.3 and an occupation of the lattice points 0, 0, 0 and 1/2 , \ba1/2 , \ba1/2 with a preference of the Mn atoms for one of these points. The Mn-Al alloy may be heat-treated to obtain the tetragonal phase by either (1) heating at a temperature below 1000 DEG  C. for a sufficient time, or (2) cooling between 825 DEG  and 600 DEG  C. at a rate of 0.5-100 DEG  C./second, or (3) cooling to below 825 DEG  C. at a rate of more than 100 DEG  C./second and then heating between 825 DEG  and 600 DEG  C. for a sufficient time.  Homogenization before and annealing at 200-600 DEG  C. after the phase-production heat treatment is beneficial. Particles for the production of the magnet may be produced by either (1) effecting solid state diffusion of powders of the constituent metals or pre-alloys thereof or (2) pulverizing a cast or sintered Mn-Al body with or without a prior heat treatment so that the brittle b  phase is obtained.  The particles are then heat-treated to produce the tetragonal phase. Alternatively the body may be pulverized after the phase-production heat treatment. The particles are formed into a magnet by compression with or without sintering; they may be oriented in a magnetic field before or during compression.  Specification 771,538 is referred to.

Abstract: 762,928. Magnetic recording and reproducing apparatus. RADIO CORPORATION OF AMERICA. Nov. 11, 1954 [Nov. 27, 1953], No. 32739/54. Class 40 (2). [Also in Group XXXIX] Variation in the sensitivity of a magnetic tape is compensated for by automatic volume and/or tone control in the recording circuit. A test tone is applied to the tape at 9, reproduced at 10, and erased at 11. The test signal and reproduced test signal are combined differentially in a network 19 and applied to a variable-gain amplifier 26 to vary the volume of the signal which is recorded at 12. In a simplified arrangement the reproduced tone, after rectification at 23, may be applied to the v.g. amplifier. To compensate for variation in tone, a test tone of say 8000 c/s. is used. This tone is affected markedly by variation of the bias from the optimum. The output from network 19 or rectifier 23 is applied to a bias oscillator 29. Both volume and tone control are provided in a modification (Fig. 2, not shown), the two test tones being of different frequencies and the outputs being filtered.

Title: Improvements in the production of steel from crude iron containing phosphorus
IPC: C21C5/32
Filed: 1954-11-12
Abstract: A method of refining phosphorus containing raw iron in a converter using air, oxygen enriched air, or a mixture of oxygen and steam, comprises blowing oxygen rich gases periodically on to the surface of the bath and continuously or intermittantly adding cooling oxygen carriers to form a liquid, basic oxidizing slag, the dephosphorizing period being brought wholly or partly into the decarbonizing period, and the rate of decarbonization being maintained at 0.15 per cent to 0.20 per cent per minute.  A lance may be used for surface blowing which may be carried out until dephosphorization is complete, the remainder of the decarbonization, if required, being performed by bottom blowing. Slag forming materials, e.g. lime, may be added at the beginning or in portions during the refining and the cooling oxygen carriers, e.g. oxidic iron ore or mill scale, added continuously during blowing.  The area of the bottom tuyeres may be reduced. The pressure of gas blown on the surface should be so low that the slag layer is not penetrated.
