Title: Improvements in Electric Motor Control Systems.
IPC: H02P7/06
Filed: 1917-05-03
Abstract: 110,311. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). May 3, 1917. Systems for continuous-current motors only.- A control system for a motor variable in speed by field regulation includes a controlling switch with actuating windings in the field and armature circuits, and having a varying sensitiveness to varying armature conditions. The motor is started by the closure of the switch 2 following the depression of the button 3, and the contactors 4, 5, 6 operate in succession to cut out sections of resistance from the armature circuit. The last contactor 6 removes a short circuit from the field circuit resistance R leaving that resistance under the control of a vibrating relay 7 with additive windings 7<a>, 7b which carry the armature and field currents respectively. The magnetizing force of the coil 7b is at its maximum prior to the initial inclusion of the resistance R and is gradually decreased as the field is weakened by the intermittent inclusion of the resistance. The magnetizing force required from the winding 7a to effect response of the relay, therefore increases as the speed rises, so that the sensitiveness of the relay to surges in the armature circuit decreases as the field is weakened. An overload switch 8 is provided with windings similar to those of the relay 7.
Patent GB-462494-A (GB)
Title: Improvements in and relating to the production of substances in the colloidal state
IPC: B02C4/04
Filed: 1936-03-02
Abstract: <PICT:0462494/III/1> A method of grinding or disintegrating solid substances comprises crushing the material between a pair of rollers coated continuously with a film of tacky material such as the soft extract of oxgall and lignin in the almost solid state and substances such as glucose and sugars made tensioactive by the addition of substances such as substituted and sulphonated naphthalenic acids, glucosides, alkaline silicates, products such as casein, gums and resins which become tensioactive in contact with an alkaline solution: phenols, formaldehyde condensation products which are soluble in organic solvents can also be used. For foodstuffs, substances like gluten, milk or honey are suitable.  The film is a few hundredths of a millimetre thick and is almost rigid in its concentrated state and it can be dissolved in a solvent after being removed from the rollers, the finest particles being extracted in the form of a liquid which can be concentrated to the form of a reversible paste which may be purified by steam, microbic fermentation, enzymes, &c.  The paste may be treated with liquified gases such as sulphur dioxide, ammonia, &c. or by means of decantation with such agents, the remaining trace of gases being removed by heating under vacuum. At the same time the substance of the film is recovered by distillation of the gases so that the process forms a closed circuit.  If the substance becomes oxidized before or during disintegration it may be reduced by nascent hydrogen &c.  The energy used in crushing is regulated by connecting one roll, which is driven by contact with the other roll, to an energy recovering device such as an oil pump or electric brake.  As shown, the rolls A, B are pressed together hydraulically and are maintained at a constant temperature by an internal circulating fluid.  The tacky film is supplied to each roller by a receptacle EN, a feed cylinder PR, and oscillating table TA which may be heated, two crushing cylinders BR and a contact cylinder TO.  The substance to be treated, of granular form and moistened, is stored in a hopper D and falls in a thin stream between the film covered rolls.  A knife C or auxiliary cylinder removes the substance from the roll B which rotates faster than the roll A, the latter roll being connected to an oil pump or electric brake.  The rollers may be pressed together by other rollers forced into contact therewith by a hydraulic plunger. The film used may form part of the final product, for example tricalcium phosphate reduced to a colloidal state by means of films of lignin or cane sugar can have the selected ferments or microbes added to it.  By dilution with the water for watering plants, the fermentation is started, the microbes consume the sugar and the products attack the phosphate which can thus be completely assimilated.
