Title: Improvements in or relating to the production of triamino-monocyclic aromatic hydrocarbons
IPC: C07C209/36
Filed: 1945-03-28
Abstract: Triamino monocyclic aromatic hydrocarbons or their hydrates, of the kind in which the three amino groups are in the meta-position with respect to one another, are prepared by reacting the corresponding trinitro compound, dissolved in a saturated aliphatic ester solvent, with hydrogen, in the presence of Raney nickel catalyst.  The reaction may be started at room temperature and allowed to warm up, and may be carried out at atmosphere or increased pressure.  In examples: (1) 1 : 3 : 5-triaminobenzene, dissolved in ethyl acetate, with hydrogen in the presence of Raney nickel, filtering and cooling the filtrate; (2) 2 : 4 : 6-triaminotoluene is similarly prepared; (3) 2 : 4 : 6-triaminotoluene is similarly prepared using a mixture of ethyl and butyl acetates as the solvent; (4) 2 : 4 : 6-triaminotoluene is similarly prepared using diethyl carbonate containing 5 per cent of acetone as the solvent; (5) 2 : 4 : 6-triaminoethylbenzene is prepared as in (1) from trinitroethylbenzene.  The Provisional Specification refers also to the use as solvents of an aliphatic alcohol containing up to four carbon atoms, an aromatic hydrocarbon, e.g. benzene, or an aliphatic hydroxy ether, and refers also to the isolation of triamino compound formed as a salt, e.g. as the trihydrohalide, as the acyl derivative, e.g. the triacetyl derivative, or as the product obtained by diazotization.

IPC: C07J41/00
Filed: 1952-03-31
Abstract: 17-Amino compounds of the steroid series containing a hydroxyl group in the 3-position or salts thereof are prepared by hydrolysing a 17-acetylamino compound of the formula RNHCOCH3, wherein R represents a saturated or D 5-unsaturated cyclopentanopolyhydrophenanthrene radical containing a hydroxy or acyloxy radical in the 3-position, by means of an inorganic alkaline substance at a temperature above 95 DEG  C., and, if necessary, converting the 17-amino compound into a salt with an inorganic or organic acid.  The hydrolysis may be carried out at atmospheric or superatmospheric pressure, and a solvent boiling above 95 DEG  C. or an organic base may be used as the reaction medium.  Suitable inorganic alkaline substances are alkali metal and alkaline earth metal hydroxides and alkali metal carbonates.  The salts may be derived from acetic, oxalic, succinic, benzoic, phthalic, sulphuric, hydrochloric and perchloric acids.  In the examples, 3b  - hydroxy - 17 - amino - D 5 - androstene is prepared from the corresponding 17-acetylamino compound and from 3b -acetoxy-17-acetylamino-D 5-androstene and is converted into a hydrochloride, acetate or oxalate salt, 3b -hydroxy-17-amino-androstane is prepared from 3b  - acetoxy - 17 - acetylamino - androstone and is converted into the acetate salt, and 3b  - hydroxy - 17 - amino - aetiocholane is prepared from 3b -acetoxy-17-acetylamino-aetiocholane and is converted into the acetate salt.  The 3b  - hydroxy - 17 - amino - D 5 - androstene may be purified by forming the benzal derivative by reaction with benzaldehyde, and the benzal derivative is then converted into the 17-amino compound by reaction with concentrated hydrochloric acid in alcohol.  Specifications 501,421 and 747,603 are referred to.

IPC: G01J3/42
Filed: 1951-04-10
Abstract: 684,820. Valve amplifying circuits. INTER-CHEMICAL CORPORATION. April 10, 1951, No. 8280/51. Class 40 (vi). [Also in Group XL (b)] In a system in which the output of a photo-cell receiving light alternately from a standard and comparison source brings a centre zero meter to a zero reading when the two beams balance, degenerative feed-back is employed in the amplifier feeding the meter so as to eliminate from the output all frequencies other than the beam alternation frequency. Circuit.-The photo-electric cell 3 has its anode connected to the H.T. point while its cathode is connected to the control grid of a pentode 65. The output signal developed across the anode load 71 of this pentode is applied through a condenser 72, a further pentode 73 and a resistance capcity coupling to one grid of a cathode-coupled pair 86, one anode of which is connected direct to the H.T. line while the signal developed at the other across an anode resistor 93 feeds one grid of a second cathode coupled pair 88 through a direct connection. The signal developed across anode resistor 110 is fed to an output valve 121 in the anode circuit of which is the primary of an output transformer 127, and is fed back to the second grid 100 of the first cathode coupled pair, through an asymmetric T filter 116. The values of this filter are so chosen as to degenerate all except the beam interrupter frequency while the connection to the output of the second cathode coupled pair provides a low input impedance to the filter and the connection to the output of the first pair provides a high output impedance. The secondary of the output transformer feeds a centre zero meter 5 fed with a reference 6 v. A.C.

Abstract: 579,732. Surface carburetters. PEARCE, M. June 18, 1942, No. 8352. [Classes 7 (ii) and 7 (iii)] An evaporating system for methane or like fuel stored in liquid form in a lagged tank having a loaded venting valve comprises an evaporator, such as an inverted conical dish or a series of tubes 1 supplied with liquid from below, the level of the liquid being determined by the vapour pressure in the evaporator which is formed so that it presents no recesses to prevent draining of the liquid back into the supply conduit and tank when the system is inoperative. The liquid is conveyed to the tubes 1 by a diverging chamber 5, and a vapour-collecting chamber 6 is provided at the top. The tubes may be surrounded by a telescopic jacket 8, 9, through which is circulated by pipes 10, 11 a heating-fluid, such as the engine exhaust, or cooling-water, or products from a burner; or the atmosphere may be used, the vessel being finned.

Title: Improvements in roving package winding apparatus
IPC: D01H1/36
Filed: 1962-02-27
Abstract: 973,272. Building roving packages with curved ends. INSTITUTE OF TEXTILE TECHNOLOGY. Feb. 27, 1962 [April 25, 1961], No. 8386/64. Divided out of 973, 168. Heading D1D. In a roving frame builder mechanism the length of each layer of roving is varied in a non- linear manner with respect to the bobbin diameter so that a roving package with curved end profiles is produced. In known roving frame builder mechanisms successive half revolutions of a builder dog 23 and its associated tumbler shaft 22 cause (through mechanical gearing) equal successive rotations of a builder shaft 18 and thus equal successive decreases in the length of roving lay. However, in the form shown a rack 100 which is directly geared to the shaft 18 in the normal manner is moved through progressively increasing increments for each half turn of the tumbler shaft 22. To achieve this, a template 93 attached to the rack 100 is biased by a spring 101 and held against movement by either one of a pair of solenoids 95, 96 engaging pins 94 arranged in two rows on the template; the solenoids are alternately energized by switches 91, 92 at each 180 degrees rotation of the builder dog 23 and at each energization the template moves through an increment which becomes progressively larger due to the non-linear spacing of the pins in each row. Thus the successive decreases in the length of the roving lay become larger and a package with a curved end profile is produced. By suitable spacing of the pins a sine-wave contour is produced at the ends of the package. By spacing the pins equally in those areas of the template associated with the beginning and end of the build conical tapers can be provided at these parts of the build. Specification 921,375 also is referred to.
