Title: Improvements in or relating to control systems for controlling the movement and/or displacement of a member
IPC: G01D5/36
Filed: 1963-08-06
Abstract: 1,107,982. Photo-electric position & movement determination; measuring displacement electrically. C. R. COOKE. Sept. 24, 1964 [Aug. 6, 1963], No.31007/63. Headings G1A and G1N. [Also in Division G3] The invention is concerned with a development of the position and movement determining systems disclosed in Specifications 991, 907, and 1, 096, 022 so that the system output can be applied to a servodevice in the form of a set of signals which are mutually in-phase or anti-phase and of amplitudes whose resultant is zero. In the prior systems it was normal to derive three phase output signals of equal frequency each varying about a positive datum level in accordance with position. To produce the signals required a biasing A. C. of fixed amplitude in anti-phase relationship may be applied to each detector output. Alternatively each of the phase output signals may be derived from a pair of detectors associated with parts of a reference grating half of the line spacing apart; the algebraic sum of the detector outputs being taken. The servo device may be part of a system for controlling a process in accordance with a programme recorded, for example, on magnetic tape. The tape may carry three recorded signals or three pairs of phase-opposed signals and these may be duplicated to give fine and coarse control and further increased for two dimensional arrangements. The tape information, either in the form of amplitude or frequency modulated signals, is compared with the positional signals from the test object and error signals derived and applied to ensure the test object moves as required by the programme.

Title: Process for the manufacture of alkanolamines
Inventor: GRAHAM ARCHIBALD ROBERT
IPC: C07C215/06
Filed: 1950-12-20
Abstract: Mono- and di-2 : 3-butanolamines, substantially free from tributanolamines, are manufactured by reacting 2 : 3-epoxybutane with ammonia, advantageously at 70-180 DEG  C. (preferably 90-120 DEG C.).  The starting material should be practically free from 1 : 2-epoxybutane, i.e. the proportion of the latter should be less than 30 per cent, preferably less than 5 per cent, a suitable starting material being the product obtained by liquid phase oxidation with molecular oxygen of a butene-2 containing not more than 10 per cent of butene-1.  The molar ratio of ammonia to 2 : 3-epoxybutane is advantageously less than 10 : 1, preferably less than 5 : 1.  If it is 1 : 2, the product is substantially pure di-2 : 3-butanolamine. With excess of aqueous ammonia, mono-2 : 3-butanolamine is mainly formed, pure trans- and cis-2 : 3-epoxybutane yielding respectively the erythro- and threo-forms thereof, which are characterized by their normal (erythro only) and acid oxalates, N-benzoyl, N-p-nitrobenzoyl and N-p-toluenesulphonyl derivatives and phenylthioureides.  In examples: (1) pure trans-2 : 3-epoxybutane is heated with 3 molecular proportions of aqueous ammonia to produce a mixture of mono- and di-2 : 3-butanolamines from which the former (erythro-form) crystallizes on standing; (2) the molar ratio of ammonia to epoxybutane in (1) is reduced to 1 : 2, the product being mainly di-2 : 3-butanolamine; (3) cis-2 : 3-epoxybutane is treated as in (1), but using 4.5 molecular proportions of ammonia, yielding threo-3-aminobutan-2-ol and some di-2 : 3-butanolamine; (4) cis-2 : 3-epoxybutane is treated as in (2); (5) a mixture of cis- and trans-compounds is heated with 5 molecular proportions of aqueous ammonia; (6) a mixture somewhat richer in cis-compound is heated with 0.34, 0.55, 1.0, 1.25, 2.5 or 5.0 molecular proportions of aqueous ammonia; (7) the starting material of (5) is heated with 5.5 molecular proportions of aqueous ammonia in a continuous process; (8) similar starting materials are similarly heated with 5.3 or 5.1 molecular proportions of ammonia. Experiments are also described in which (a) di-2 : 3-butanolamine is heated with 1 : 2-epoxybutane in the presence of water, forming a mixed tributanolamine, and (b) a 1 : 2-mixture of 1 : 2-and trans-2 : 3-epoxybutanes is heated with aqueous ammonia, the molar ratio of ammonia to total epoxides being 1 : 2, whereby a mixed dibutanolamine is formed together with a mixed tributanolamine. Specification 708,913 is referred to.  2 : 3 : 5 : 6-Tetramethylmorpholine is obtainable by dehydration of di-2 : 3-butanolamine, e.g. with concentrated sulphuric acid. Specifications 448,373 and 497,093 also are referred to.

Abstract: 651,239. Locking levers. SMITH & SONS (ENGLAND), Ltd., S., and WOOD, F. H. Dec. 1, 1948, No. 31160. [Class 80(iii)] A detent 16, loaded by a spring blade 20 and having both rectilinear and pivoting movement about a stationary pin 15 engaged in a slot 18 thereof, provides, by an L-shaped slot 17 having a hook-shaped portion 19, an intermediate detaining position between two limiting positions of a lever 12 pivoted at 13 and loaded by a spring 22. In one limiting position, Fig. 1, the spring 20 loads the detent 16 in a clockwise direction, but on clockwise movement of the lever 12 its pin 14 engages the hook 19 to move the detent 16 upwardly to the immediate position, Fig. 4, wherein the spring 20 then loads the detent 16 in an anticlockwise direction following movement of the free end of the spring 20 past the pin 15. The detent 16 moves in this direction on slight reversal of the lever 12 which is then permitted further clockwise movement to the other limiting position, Fig. 6. The Provisional Specification states that the mechanism is particularly suitable for levers of multi-position electric switches or change speed gear boxes.

Title: Methods of amide synthesis
IPC: C07F9/6571
Filed: 1959-09-16
Abstract: A process for preparing an amide comprises condensing one mole of an acid RCOOH with one mole of an amine R1NH2 (where R and R1 are organic radicals) in the presence of (a) substantially one mole of a dialkylene, dialkylalkylene or tetra-alkyl pyrophosphite and substantially 0.25 to 1.25 moles of an imidazole, or (b) substantially one mole of an alkylene phosphor-N-imidazolite or O-phenylene phosphor-N-imidazolite. The process is of particular use in the preparation of peptides by condensing N-blocked amino acids with amino acid esters.  Examples describe the use of diethylene, diethylethylene and tetraethyl pyrophosphite together with imidazole and N-methyl-imidazole and of ethylene phosphor-N-imidazolite and O-phenylene phosphor-N-imidazolite in the preparation of tert. butyl carbobenzoxyglycyl-DL-phenylalaninate, ethyl tert. butyloxycarbonyl-L-leucyl glycinate, methyl tert. butyloxycarbonyl-L-prolyl-L-phenylalaminate, ethyl tert. butyloxycarbonyl-L-phenylalanyl-glycinate and ethyl carbobenzoxyglycyl-L-phenylalanyl-glycinate and ethyl carbobenzoxyglycyl-L-tyrosinate.  Ethyl-L-phenylalanylglycinate hydrobromide is prepared from the tert. butyloxycarbonyl derivative. Carbobenzoxyglycine-phosphorous acid anhydride is prepared by reacting the amino acid with tetra-ethyl pyrophosphite in diethyl phosphite.  Ethylene phosphor-N-imidazolite is prepared by reacting imidazole with ethylene chlorophosphite. O-Phenylene-phosphor-N-imidazolite is prepared by reacting imidazole with O-phenylene chlorophosphite.  Specifications 714,018 and 872,332 are referred to.

Title: Apparatus for the detection of faults in measuring systems including electronic means
IPC: G01N27/12
Filed: 1953-11-13
Abstract: 741,033. Correspondence control systems. BAILEY METERS & CONTROLS, Ltd. Nov. 13, 1953 [Nov. 13, 1952], No. 31568/53. Class 40(1) A self-balancing measuring system comprises warning devices indicating (i) emission failure of electron tubes or valves (ii) impediment to movement of the balancing element e.g. sluggish rotation of balancing motor due to faulty bearings (iii) failure of electric power supply; and also if desired and if appropriate (iv) open circuit in d.c. windings of transductor (v) failure of fluid supply (i.e. specified primary variable), to predetermined extent. The invention is presented in Figs. 1 and 2 which are otherwise of known form or arrangement. In Fig. 1 a temperature-variable resistor type of gas analyzer 2 continuously voltage-feeds network 5 so that control tube 7 energizes motor winding 8 and normally the twophase capacitor-run induction motor 6 operates correctly and rebalances the network 5. The capacitor 12/motor winding 8 is tuned to supply frequency and the A.C. voltage thus produced across motor winding 8 reaches predetermined limit before motor 6 rotates but if motor 6 is mechanically impeded the A.C. voltage goes above the set limit and a lamp 20 glows and warns the operator. The lamp 20 is prevented from spurious glowing by (see 23A), a wave trap at twice the supply frequency and a series condenser which accepts D.C. ripple. If the motor control tube 7 fails no voltage of any character will appear across winding 8 and a lamp 23 in series with the winding will thereforego out. A pilot lamp 24 goes dark if the power supply fails. The lamps may be associated with relays so that on the occurrence of a fault control action safeguarding the process &c. is automatic. The gas analyzer 2 receives sample fluid through a pressure regulator 4 and failure is indicated when magnet 26 in the regulator 4 attracts switch arm 26' and this closes circuit to lamp 28 and if desired operates a relay to control the fluid pressure. In Fig. 2 the double-triode control tube 30 drives motor 6 dependently on saturation unbalance between transductors 31, 32 and capacitor 35 is effectively in series with stator 33 or 34. If motor 6 is retarded the voltage across capacitor 35 rises to energize lamp 20. If emission on one side of tube 30 declines or a D.C. winding burn-out occurs in transductor 31 or 32 the impedance of the A.C. winding of the affected transductor will rise considerably and motor 6 will adjust network 5 to drive the anode of the active or unaffected side of the tube 30 more negative so that total blockage in tube 30 is sufficient to extinguish lamp 23 and the motor 6 may reach one extreme of travel so that a limit stop turns on lamp 20. Specifications 660,105, 698,456 and 740,436 [both in Group III], are referred to.
