Title: New metalliferous disazo-dyestuffs, containing monohalogen triazine residues, and their manufacture and use
IPC: C09B45/24
Filed: 1958-09-29
Abstract: The invention comprises metal complexes which contain one atom of chromium or cobalt bound to two molecules of a disazo dye, in which a monohalo-1 : 3 : 5-triazine residue is bound on the one hand through an amino bridge to a metalliferous monoazo dye residue and on the other through an amino bridge to a metal-free monoazo dye residue, wherein both monoazo dye residues contain at least one sulphonic or carboxylic acid group.  They may be obtained by preparing a metallisable azo dye in the usual manner, the components being chosen so that the dye obtained has at least one sulphonic or carboxylic acid group and an acylatable amino group and converting it into a 1 : 2-cobalt or -chromium complex. The amino group in the dye may be obtained by reduction or saponification of a nitro or acylamino group.  One mol of the 1 : 2-complex is condensed with 1 mol of a trihalotriazine and the resultant dihalotriazine derivative is condensed with 1 mol of a suitable metal-free aminoazo dye.  Many suitable components are specified.  The process may be modified in various ways by altering the sequence of reactions.  The dyes give various shades on wool, superpolyamides, superpolyurethanes, leather and cellulose fibres, particularly cotton.  In examples: (1) the 1 : 2-cobalt complex of 1-hydroxy-2-(21-hydroxy - 51 - sulphophenylazo) - 6 - amino-naphthalene-3-sulphonic acid is prepared and condensed with 41-(3 : 5-dichlorotriazinylamino)-4-hydroxy-3-carboxy-azobenzene; (2) the cobalt complex specified in (1) is condensed with cyanuric chloride and the dihalotriazine derivative is condensed with 2-methyl-4-amino-5-methoxy-azobenzene-21 : 51 - disulphonic acid; (3) the dichlorotriazine derivative prepared as in (2) is condensed with 2-amino-5-naphthol-7-sulphonic acid and the resultant monohalotriazine derivative is coupled with diazotised 2-amino-benzenesulphonic acid; (4) 2 : 4-diamino-benzenesulphonic acid is condensed with cyanuric chloride, the dichlorotriazine derivative is condensed with the 1:2-chromium complex of the dye specified in (1) and the monochlorotriazine derivative is diazotised and coupled with 1-phenyl-3-methyl-5-pyrazolone.

Title: Dispensing machine
IPC: G01G23/00
Filed: 1960-09-12
Abstract: 907,049. Weighing apparatus. HESSER, MASCHINENFABRIK-A.G., Fr. Sept. 12, 1960 [Oct. 7, 1959], No. 31343/60. Class 143. A dispensing machine which operates on the volumetric principle and has measuring chambers which are adapted to be adjusted automatically by a control measuring device in accordance with the varying poured weight of fluent material passing into the machine is characterized by the fact that the control measuring device, which comprises an adjustable control measuring chamber 16 and an associated control-signal-emitting weigher 17, is arranged directly at the periphery of and in parallel with the distributer plate 2 which supplies the measuring chambers 1 and is provided with a conveyer device which takes fluent material from the distributer plate and fills it into the control measuring chamber. Fluent material is fed on to the distributer plate 2 through a pipe 3 and is swept into the measuring chambers 1 by wiper blades 7, 8. The control measuring chamber 16 is the same size as a measuring chamber 1 and the conveyer device which fills it comprises wiper blades 5. After each revolution of the wiper blades 5 the chamber 16 is discharged by the opening of a bottom flap 20, ingress thereto of further material being stopped by a rotating cover-plate 19. The discharged material falls into the weighing holder 18 of the weigher 17. If the material thus measured out has an underweight or an overweight a corresponding positive or negative electrical impulse is passed to control mechanism 26 from a differential transformer 25, of known type, connected to the weigher. The mechanism 26 controls a motor 34 which drives a screwthreaded spindle 37 whereby, for each right-hand or left-hand rotation of the motor 34, the distributer plate 2 and cover 31 are respectively raised or lowered, the volume of the measuring chambers 1, which are telescopic, thus being increased or decreased. The volume of the chamber 16 is varied simultaneously. The control mechanism 26 may be adapted, either to use each control weighing to correct the dispensed volume of material, or to add up the electrical impulses and initiate an adjustment after a certain sum, so correcting any tendency to over- or under-weight. Material that has passed through the weighing device and excess material taken from the distributer plate 2 by the wiper blades 5 is returned to the distributer plate by a conveyer 28. Regulation of the quantity conveyed by the wiper blades 5, which may be observed in a mirror 30, can be achieved by rocking a guide-plate 32. There may be more than one chamber 16.

Title: Improvements relating to sawtooth waveform generators
Inventor: WHITE ROBERT CYRIL
IPC: H03K4/43
Filed: 1949-12-08
Abstract: 677,850. Saw-tooth generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Dec. 8, 1950 [Dec. 8, 1949], No. 31467/49. Class 40 (vi). The invention relates to a saw-tooth wave generator of the type in which saw-tooth voltages generated by charging a capacitor slowly and discharging it through a valve are fed to an amplifier valve having an inductive output circuit which, when the output electrode current is cut-off, produces a pulse which is fed to the discharging valve to render it conductive and so produce the fly-back. According to the invention a synchronizing signal is fed to an outer control electrode which does not draw current. In the circuit shown, the scan portion of saw-tooth waves generated by charging capacitor 3 through a resistor 4 are linearized'by means of an integrating circuit 9, 10 and applied to the grid of an amplifier valve 2 producing a saw-tooth wave in the scanning coils. On the occurrence of a synchronizing pulse from a source 20 the current in valve 2 is cut off, producing a large positive voltage at the anode and this is applied through a feed-back capacitor 16 to the grid of a discharger valve 1 to cause it to discharge the capacitor 3. Grid current charges the feed-back capacitor, cutting off the discharger valve, but this charge rapidly leaks away, the valve being maintained non-conductive during the scan by the decreasing voltage at the anode of the amplifier. Potentiometer 5 adjusts the amplitude of the saw-tooth produced and either of the feed-back components 16, 17 will adjust the frequency. The feed-back may alternatively be obtained from the secondary or a teritary winding of the output transformer or from an inductor in another output electrode such as the screen grid.
