Title: Shot volume control for injection moulding machine
IPC: B29C45/46
Filed: 1972-02-10
Abstract: 1372631 Controlling shot volume GENERAL ELECTRIC CO 10 Feb 1972 [1 Nov 1971] 6376/72 Heading B5A [Also in Division G3]  An injection moulding machine 10 comprising a rotating and reciprocating feed screw 18 is provided with a control system for automatically ensuring the correct shot volume for a mould 42. The control system shown ensures that the shot volume is correct by monitoring the cushion remaining in the chamber 38 of the screw barrel 13 after each injection. The latter is achieved either by using a pressure transducer 74, (e.g. a strain gauge) in the chamber 38 or in the hydraulic, reciprocating drive cylinder 28 to measure the cushion pressure or by measuring the linear velocity of the screw 18, e.g. with a tachometer during the injection stroke. The control system may be implemented in a digital and/or analogue form. The system may include three potentiometers 62, 64, 66 which are manually set at the commencement of operation of the machine to respectively produes an approximately correct return position of the screw 18, injecting position of the screw 18 and quantity of cushion. The system also includes a potentiometer 50 for determining the position of the screw 18 within the barrel 13, three summing junctions 56, 58, 60 each of which compares the signal from the potentiometer 50 with that from the respective manually set potentiometer 62, 64, 66, the junction 58 also receiving an error correcting signal obtained by algebraically summing in an integrating read and hold circuit 68 the output from the junction 60 with that from a one shot multivibrator 84 connected to a read and hold circuit 72 and strain gauge 74. The circuit 68 comprises an amplifier connected in parallel with a capacitor. The circuit 72 comprises a gated amplifier. The operation of the system throughout a working cycle of the screw 18 is explained.

Patent GB-349472-A (GB)
Title: Process of eliminating arsenic from acids, particularly sulphuric acid
IPC: C01B17/90
Filed: 1930-02-26
Abstract: Arsenic is removed from acids, particularly sulphuric acid and more especially containing also SO2, such as washing acid from the contact process, by treatment with oxyacids of sulphur containing at least two directly linked sulphur atoms, such as thiosulphuric or other polythionic acids or their salts or mixtures of the same, at temperatures below 70 DEG  C. and preferably below 60 DEG  C. Concentrated acids, particularly sulphuric acid of 50-66 DEG  B<\>ae and over, may be treated by the process, substantially all of the arsenic being precipitated as sulphide. The estimated theoretical quantity of thiosulphate, for example in solution form, may be added with thorough mixing, the temperature preferably being kept below about 35-50 DEG  C.  Sodium, ammonium, barium, or other alkaline or alkaline-earth thiosulphate may be used.  By the use of thiosulphates such as those of barium or lead for purifying sulphuric acid, the metals are precipitated as sulphates and removed together with the arsenic sulphide.  Excess of thiosulphate may be added and afterwards removed, for example by the addition of an oxidizing agent such as hydrogen peroxide, prior to filtration.  In the treatment of acids containing higher nitrogen oxides, such as nitric or nitrous acid, these oxides are preferably removed prior to the precipitation, for example by treating with SO2 or an air blast.  Acid used for washing the roast gases in the contact process can be purified by the above process and used for absorbing SO3, or when re-employed as washing acid elimination of the major portion only of the arsenic may be effected without the necessity of adding an excess of the precipitant.  The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the use of temperatures below 70 DEG C., and states that denitration of acid solutions may be effected by adding urea.  Separation of the arsenic sulphide precipitate is facilitated by addition of inert finely divided substances, such as sand or fused alumina, either before, during, or after the precipitation.  This subject-matter does not appear in the Specification as accepted.

Title: Aircraft with jet engines arranged symmetrically for producing lift
IPC: B64C29/00
Filed: 1962-02-20
Abstract: 955,364. Jet propelled and supported aircraft. DORNIER-WERKE G.m.b.H. Feb. 20, 1962 [Feb. 21, 1961], No. 6458/62. Heading B7G. An aircraft having direct lift jet propulsion engines arranged symmetrically has one or more further jet propulsion engines arranged in or on the fuselage for producing forward thrust, and duct means arranged to conduct part of the gases of the further engines to direct lift nozzles, either symmetrically to assist in lifting, or asymmetrically in the case of failure of an engine, to maintain a symmetrical total lift force. In Fig. 1, engines T1 and T2 normally feed direct lift nozzles 1, 2, and 4, 5, respectively. Engines T3 and T4 on the fuselage provide forward propulsion, and part of their working fluid such as by-pass air may be led through taps 7, 8, valve 9, and ducts 10, 13, to downwardly directed nozzles 11, 12, on the undersurface of the wings. Part of the working fluid is led to control jets at the tail, as indicated at 16. Should either engine T1 or T2 fail, the whole or most of the gases in duct 10 are led to the appropriate one of nozzles 11 and 12, to prevent excessive rolling moments. Alternative nozzles such as 11<SP>1</SP> and 12<SP>1</SP> may be chosen to correct rolling moments more exactly. The duct between each engine T1, T2 and its inboard nozzle contains a valve 3, 6, connected by branch 14, 15, to duct 13, so that if say, engine T1 fails, it can be isolated from nozzle 2, which is then fed through duct 14 from duct 13, either by engines T3 and T4, or by engine T2, which then feeds only nozzles 2 and 4. Valve movements may be made manually or automatically. Should there be only one horizontal propulsion engine, and should that fail, the valve 9 may feed the control jet duct 16 from engines T1 and T2.

Title: Improvements in or relating to processes for the acid saccharification of amylaceousmaterials
IPC: C12P7/06
Filed: 1948-03-05
Abstract: The aqueous residues resulting from the acid saccharification of amylaceous materials and the alcoholic fermentation and distillation of alcohol therefrom are subjected to acid hydrolysis, after adjustment of the concentration of the non-fermentable sugars to not more than 3 per cent, with a quantity of acid which is sufficient to produce pH 1.8-2.3 and is 8-15 per cent, calculated as hydrochloric acid, of the non-fermentable sugars, for a shorter period than that of the initial saccharification.  The hydrolysis may be at 140 DEG -160 DEG C, e.g. by injecting steam into the acidified residues in a closed vessel at 3 1/2 to 6 1/2 atmospheres pressure, for 15-40 min. According to an example, 450 l. of a suspension of 100 kg. of maize flour in water to which has been added 2.8-3.3 per cent of hydrochloric acid, calculated on the carbohydrate content of the flour, is heated at 100 DEG C with agitation until liquefaction occurs, the solution is heated then for 60 min. under a steam pressure of 4 kg./sq cm., is cooled, adjusted to pH 5.5, submitted to alcoholic fermentation and the alcohol distilled off; to the residue, which contains 17.20 g./l. of non-fermentable sugar, sufficient dilute hydrochloric acid to produce pH 2.1 and 12.5 per cent H.C1 with respect to the sugar is added, and the solution is heated for 30 min. under a steam pressure of 4 kg./sq. cm.
