Patent GB-286836-A (GB)
Title: Improvements in or relating to electric relays or switches
IPC: H01H50/20
Filed: 1927-01-20
Abstract: 286,836. General Electric Co., Ltd., and Angold, A. E. Jan. 20, 1927. Electromagnetic switches, such as voltageregulating switches in which sluggish action of the movable contact member is prevented by a force the effectiveness of which varies in such a way that it assists the force or forces initiating the contact movement, have an additional force arranged to act upon the movable contact member so as to give this member a degree of stability at an open or intermediate position. As shown in Fig. 1 the core 7 of a solenoid 8 is suspended from a knife edge 6 resting on one arm of a lever 1 moving about a fixed knife-edge 2. The other arm carries a counterweight 14 adjustable along its length and a contact 3 working between fixed contacts 4, 5. The lever has a third arm 9 extending upwardly above its fulcrum and bearing an adjustable weight 11. This weight 11 by moving to one side or other of its central or ineffective position assists the force or forces initiating movement of the contact member, the pull on the solenoid core when above its normal value due to excessive voltage raising the core and moving the contact 3 from contact 4 to contact 5 and when below its normal value due to reduced voltage permitting the core to drop and transfer the contact 3 from contact 5 back to contact 4. The action of the weight 11 by assisting the movements in either direction causes a quick action of the movable contact towards and from its extreme positions. In order to prevent oscillation of the contact arm between its extreme positions due to the unstable force introduced by the weight 11 and to give the contact arm a degree of stability at a central intermediate position corresponding to normal for voltages, a check weight 19 adjustably mounted on a lever 16 is so arranged that as the core rises through its intermediate position the weighted arm is picked up by the top of the knife edge 6 so that the arm immediately tends to remain in its central position until a further increase in the solenoid exoitation takes place sufficiently to overcome the extra force due to the checkweight. Similarly during the falling of the core the arm in passing through its central position is immediately relieved of the force due to the weighted arm as this abuts against the stop screw 22 and the arm remains in this position until a further decrease in the solenoid pull takes place. In a modification also described (Fig. 2) a single weight suitably arranged combines the effect of weights 11 and 14 in the arrangement described above. The biassing force for causing quick opening and closing of the contacts may also be supplied in any other suitable way as for example arranging the pull on the solenoid core to vary suitably in its relation to its position therein.

Title: Improvements in or relating to chromium-containing disazo dyestuffs
IPC: C09B31/02
Filed: 1954-01-20
Abstract: The invention comprises chromium-containing dyestuffs which in the metal-free state are of formula <FORM:0749142/IV(c)/1> where R is a residue of the benzene or <FORM:0749142/IV(c)/2> naphthalene series, is a residue of the hydroxynaphthalene or pyrazolone series and the OH-group of R2 is ortho to -azo-. The dyestuffs are made by treating the unmetallized dyestuffs with chromiumyielding agents preferably so that for 2 molecules of disazo compound less than one atom, e.g. 0.5-0.7 atoms, of metal are used.  Chroming may be effected at elevated temperature in aqueous solution or magnesium in an organic medium, e.g. in a melt of an alkali metal salt of a low molecular weight aliphatic monocarboxylic acid.  Specified chromium-yielding agents are chromic fluoride, sulphate, formate and acetate, potassium chromium sulphate and sodium and potassium chromates and bichromates. Preferably dyestuffs are obtained which have one atom of chromium per 2 molecules of disazo dyestuffs.  Wool, silk, synthetic polyamide fibres and leather are dyed from neutral to weak acid baths in yellow, orange, brown, olive or grey shades. In Examples chromium complexes are made from dyestuffs prepared from the following diazo components 3-amino-4-hydroxy-1, 11-azobenzene, 3-amino-4-hydroxy-2, 31-, - 2, 41- and 2, 51-dimethyl-, -41methyl-, methoxy-, -ethoxy-, nitro- and -tert-amyl-, -31-chloro-, 21, 41, 6-trimethyl, -21-bromo-41-nitro-and 21-methyl-41-chloro-1-, 11-azobenzene and 1 (31 - amino - 41 - hydroxy) - benzene - azonaphthalene and the following coupling components 2-hydroxy-naphthalene-4-, -6- and -7-sulphonic acid, 1-hydroxy-naphthallene - 4 - sulphonic acid and 1 - phenyl - 3-methyl-5-pyrazolone-31- and -41-sulphonic acid. In the examples chroming is also effected with ammonium chromium sulphate and further may be effected in the presence of salicylic acid under alkaline conditions.

Title: Improvements in valves
IPC: F16K1/12
Filed: 1923-01-25
Abstract: 192,398. Kruse, O. V. Jan. 27, 1922, [Convention date]. Fluid-actuated valves.-A valve device adapted to act as a throttle valve in one direction and automatically to stop a flow in the reverse direction comprises a main valve 4 adapted to cooperate with a seat 23 and formed integrally with a piston working in a cylinder supported axially in the pipe line by webs 3. The nose of the valve member has an orifice 7 controlled by a pilot valve 16 itself fitted with a loose ball valve 16<1> and carried by a hollow spindle 17 formed with rack teeth engaging a pinion 18 on a shaft extending to the outside of the casing. When the valve is open, pressure in the annular chamber 5 equals that in the pipe line owing to leakage at 21 and pipe line is also admitted to pressure in the chamber 6 through passages 7, 9, 10, 12, 11. To close the valve under hand control the valve 16 is moved to engage or nearly engage its seat when the ball valve will be pressed to its seat to allow pressure to bank up in the chamber 6. causing the main valve to move forward to follow the movement of the pilot valve. When closing automatically with reversed flow, the ball valve opens to admit fluid to the chamber 6 to close the valve, the latter part of the closing movement being retarded owing to the passage 11 being closed and the fluid being supplied to the actuating chamber through a valve controlled pipe connection 13. Where the fluid is supplied by a pump the chamber 5 may be connected by a pipe 24 to the pump casing so that in the event of the pump failing: the drop of pressure in the pipe 24 starts the closing of the valve in advance of the actual reversal of flow. The pipe 24 may be fitted with a venting valve 31 normally held closed against the action of a spring 52 by pressure supplied through a restricted pipe 47 acting on a piston,. which pressure is released by a pilot valve 41 controlled by a solenoid 43 in the 'electrical circuit of the motor driving the pump. To allow the valve to function automatically, the external worm wheel 61 is secured to the spindle 19 by a pressure actuated clutch 59 so that when the valve 41 is opened pressure on the piston 63 is relieved and the worm wheel declutched. For small valve the hand-wheel may be secured in the opening position by a pin lightly acted on by a spring.

Title: Control system for a digital read-out scale
IPC: G01G19/414
Filed: 1973-01-16
Abstract: 1419571 Counting apparatus; price x quantity calculations KUBOTA TEKKO KK (KUBOTA Ltd) 16 Jan 1973 2298/73 Headings G4A and G4D In a digital weighing scale the weight and unit price are stored and the price x quantity calculation is performed in a single circulating shift register G. Two signals CH 1 , CH 2  are derived from a code plate moved by a balance; the signals are 90 degrees out of phase and therefore together indicate whether the weight is increasing or decreasing. A discriminator A generates add or subtract pulses on separate lines accordingly and these are counted into selected positions of the shift register G via an input changing circuit F; a second discriminator B determines whether the value stored is positive or negative in relation to a predetermined zero (allowing removal of the scalepan, &c.), a lamp being lit when the weight value is negative; the weight is stored in hexadecimal (binary) form in units of <SP>1</SP>/ 16  oz. up to 16 lbs. In other selected positions of the register is stored the unit price, set in by decimal switches (Fig. 5, not shown). In order to permit the calculation the register G is provided with various output tappings giving various output signals a, γ which can be combined to modify the input signals under the control of a clock H and programmer J. First the weight value stored in the register is converted to (binary coded) decimal and this new value is stored in further positions of the register; then, one decimal order at a time, this weight value is reduced one unit at a time and the unit price added into yet further positions of the register each time so that when the decimal weight value reaches zero, a total price value has been accumulated in the register. Detailed logic diagrams are given and briefly described together with means for displaying the information in the register on display tubes (Figs. 10-13, not shown).

Filed: 1928-01-26
Abstract: 286,263. Maschinenfabrik Augsburg-N³rnberg Akt.-Ges. March 2, 1927, [Convention date]. Sluice gates.-In a device for a sluice weir for maintaining the water levels, or adjusting the flow, or for like purposes, a variable member l, o is fitted. The figure shows a device for maintaining constant, the lower water level, in which is a float a connected by a wire c to a counterweighted lever e which operates, by links g, h, i, the contact arm k of a switch, and also, by means of the variable link l, o, a lever m. If the float a rises, the contact t, u<2> is made, and the motor v lowers the sluice b; this downward movement is transmitted by the linkage l, o, m, n to the lever h, which breaks the contact t, u<2> again. The contact u<1>, t acts similarly if the float a falls. These movements of the levers h, m carry to the right of the centre of a friction plate r the friction roller, g. The plate r is continuously rotated by worm-gearing s, so that the nut p is rotated and lengthens the member l, o until the arm k again moves to the right, starts the motor v, and lowers the sluice further. These downward movements of the sluice bare in fact simultaneous, and continue until the water has sunk to its original level. A pulley d on an adjustable screw w allows the water level to be varied.
