Title: Method and apparatus for validity-testing the results of analysis apparatus
IPC: G01N33/49
Filed: 1974-06-06
Abstract: 1458883 Voltage measuring TECHNICON INSTRUMENTS CORP 6 June 1974 [11 June 1973] 25238/74 Heading G1U The output signals from an automatic analysis apparatus are checked for validity by comparing various values derived from the signals with pre-set upper and lower limit values. As described successive output signals from the analysis apparatus, for example the digitized ordinates of successive data points 40, 38, 36, 34,...., Fig. 1, on a waveform 10 produced by the automatic analysis of a sequence of blood samples, each sample being expected to produce a generally flat topped pulse, are applied to a dedicated computing system together with various tolerance values relating, for example, to the expected degree of flatness of the pulse top and to the acceptable amount of noise, and as a result the computer, by comparing each data point with both the immediately preceding data point and the average of the immediately preceding four data points, and by evaluating various functions of the results of these comparisons and of the pre-set tolerance parameters, decides whether each pulse conforms sufficiently closely to its expected form, and, if it does, evaluates an estimate of the peak height, the form of the estimator being pre-set in accordance with the particular property under examination by the analysis apparatus. The calculations performed are given in full in the Specification but are too extensive to list. However, the general approach can be seen from the following summary of the calculations performed during the "rise" phase, this being the first phase of the five phases, shown on the "current sample" in Fig. 1, into which the calculations notionally divide. As each data point arrives it is subtracted from the average of the preceding four. If the difference is numerically less than a pre-set number N a "flat" counter is incremented. If the flat count rises to a pre-set number M, then, if it has not already been concluded for some other reason, the "rise" phase stops and the "suggested value" phase begins. If, alternatively, a pre-set time after the aspiration of the current sample expires before the flat count equals M, the "rise" phase is terminated and the number of times that the data point just arrived exceeds the average of the preceding four by more than N is stored for subsequent comparison with a pre-set number L.

Title: Improvements in and relating to systems of and apparatus for electric motor control
IPC: B60L15/04
Filed: 1921-09-24
Abstract: 188,471. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 24, 1921. Master control systems; series-parallel control systems.-Systems such as series-parallel systems in which motor circuits are regrouped after resistance has been cut-out are arranged so that the change of grouping reinserts all the resistance and the return movement of the controller cuts it out again. In the arrangement shown, starting with the series switch 11 closed and the parallelling switches 12, 13 open, movement of a controller 10 from right to left cuts out resistance R<1>, R<2> from the circuit containing the motors M<1>, M<2> in series. Opening the switch 11 and closing the switches 12, 13 reinserts the full resistance, each half being connected to the corresponding motor. Return movement of the controller from left to right cuts out resistance from both motors equally and simultaneously. A reversible pilot motor 14 operates the controller. The Specification describes in detail an arrangement of two pilot motors and clutches for operating the controller together with a master controller, limit-switches, and interlocks for rendering the sequence of operations automatic.
Patent GB-727916-A (GB)
Title: Improvements in or relating to preparation of polyisocyanates
Filed: 1952-10-10
Abstract: A method for preparing organic polyisocyanates comprises mixing together in a closed system an excess of a carbonyl dihalide with a poly-primary amino compound, heating these reactants at elevated temperature of from 100 DEG  to 200 DEG  C. and superatmospheric pressure, removing the hydrogen halide by-product during the course of the reaction, removing the unreacted carbonyl halide, and recovering the polyisocyanate.  The mixing of the reactants may be effected at 10 DEG  to 30 DEG  C., and the pressure may be from about four atmospheres to that corresponding to the total vapour pressure of the reaction medium at the reaction temperature.  A diluent, e.g. benzene, chlorobenzene, toluene and chlorotoluene, may be present. In the absence of solvent 4 to 10 moles. of phosgene per mole of the amino compound or its salt may be used.  The amino compounds may be saturated or unsaturated aliphatic, aromatic or aliphatic compounds containing 2 to 4 amino groups and may also contain other groups which may be reactive with carbonyl halides.  Specified are methylene diamine, ethylene diamine, propylene di-, tri-and tetra-amines, hexamethylene di-, tri- and tetra-amines, amylene tetramine, p-aminobenzylamine, the phenylene diamines, xylene diamines, naphthylene di-, tri- and tetra-amines, fluorene di-, tri- and tetra-amines, furane diamines, biphenyl di-, tri- and tetra-amines, a benzene triamine, anthraquinone diamine, anthracene di-, tri- and tetra-amines, 4,41-diphenyl methane diamine, 4,41,411-triphenyl methane triamine, 4,41,411,4111-tetraphenyl methane tetra-amine and cyclohexyldiamine.  Pressure may be adjusted by withdrawal of hydrogen halide during the reaction.  The product can be recovered by vacuum distillation or evaporation of the solvent, and repurified by crystallization.  In example (1) p-phenylene diisocyanate is prepared by adding phosgene to a mixture of benzene and p-phenylene diamine at 20 DEG  C. in an autoclave, then heating the mixture to 120 DEG  C. while venting hydrogen chloride at a rate such that the pressure is kept at 150 lbs./sq. in.  In a generally similar manner there are prepared from the appropriate amine hydrochlorides (2) to (5) p-phenylene diisocyanate (in (3) and (4) using excess phosgene in place of solvent); (6) m-phenylene diisocyanate; (7) 2,5-tolylene diisocyanate; (8) 4,41,411-triphenyl methane triisocyanate; (9) 1,5-naphthylene diisocyanate; (10) 1,6-n-hexane diisocyanate (together with some polymeric material); (11) 4,41-biphenyl diisocyanate.

Title: Improvements in or relating to the concentration of sulphuric acid
IPC: C01B17/88
Filed: 1944-12-18
Abstract: 578,505. Concentrating sulphuric acid. HUNTINGTON, HEBERLEIN, & CO., Ltd., COPLEY, E. D., and MARCKWALD, H. G. B. Dec. 18, 1944. No. 25424. [Class 32] Sulphuric acid is concentrated by heating a body of sulphuric acid, feeding dilute acid for concentration to said body through a dephlegmator containing a packing resistant to sulphuric acid, leading the acid-bearing vapours emanating from said body through the packing in countercurrent to the feed acid and then bubbling these vapours, before they emerge from the dephlegmator, through a pool of water or through a pool of sulphuric acid which is weaker than the feed acid. The process makes it possible to maintain the vapours leaving the deplegmator at about 100‹C. and at a very low acidity. In Fig. 1 the dephlegmator 1 is provided with a bubble tray 5 containing a pool of water or of weak acid 6, fed in via pipe 10, and overflowing through pipe 9 to the distributing tray 3 which is also supplied, via pipe 11, with the acid to be concentrated. The acid distributed through the pipes 12, flows down over the packing 2 to the heated body of sulphuric acid contained in a still. Acid-bearing vapours rise through the packing, ascend about the distributing tray 3 and then bubble through the pool of water or of weak acid 6 before they emerge from the dephlegmator through the outlet 4. In the modification shown in Fig. 2 the pool 6 in bubble tray 5 is formed and maintained by condensate dropping from the surfaces of a cooling tray 13 which is supplied with cool feed acid by a pipe 14, and is fitted with an overflow pipe 15 which delivers into the mouth of the overflow pipe 9 of the bubble tray, so that the overflow feed acid bypasses the bubble tray and only acid weaker than the feed acid is contained therein. Specification 572,328 is referred to.

IPC: B23H3/02
Filed: 1965-06-17
Abstract: 1,131,716. Electrolytic deburring tools. ASSOCIATED ENG. Ltd. June 17, 1966 [June 17, 1965], No.25750/65. Heading C7B. In a method of deburring metallic workpieces by electro-chemical machining in which the workpiece and a deburring tool are maintained stationary with a gap between them during the deburring operation, the process is continued until a predetermined quantity of electricity has been consumed by the deburring operation. The quantity of electricity flowing may be measured by a coulomb meter, e.g. an ampere-second meter. As shown, a coulomb controller 15 is placed across a shunt 16 connected in series with the current path through the workpiece 13 and deburring tool 14, current being supplied via transformer 11 and bridge rectifier 12. The coulomb controller 15 contains a capacitor which becomes charged during operation of the circuit, the charge being proportional to the amount of electricity which has passed between the workpiece 13 and tool 14. When the charge on the capacitor reaches a level corresponding to the required passage of current, the voltage across the capacitor trips a voltage sensitive relay 18 which opens contact 19, de-energizing the solenoid 20 and so opening the contacts 10 to terminate the deburring operation.
