Abstract: 414,650. Converting. DALLENBACH, W., 60, Oldenburgallee, Charlottenburg, Berlin. Feb. 3, 1933, No. 3387. Convention date, Feb. 10, 1932. [Class 38 (ii).] An inverter employing grid - controlled discharge devices is prevented from falling out of step (i.e. going into internal short circuit) by the provision of sufficient resistance or reactance respectively in or associated with the apparatus feeding the D.C. circuit to prevent its external characteristic from rising above the true step limit of the inverter in the whole of the range of load. The true step limit of the inverter is the characteristic curve representing the condition at which internal short circuit occurs for various phase settings of the grid control. In one form the resistance is included in the D.C. circuit to produce a falling characteristic. In the form shown the D.C. circuit 17 is supplied from an A.C. circuit 12 through a rectifier 13 reactances 10 being provided on the A.C. side to give the required characteristic. The rectifier 13 may be grid controlled. A discussion of the theory of operation of inverters is contained in the Specification.

Title: Method of and apparatus for controlling the moisture content of moving material
IPC: D21F7/00
Filed: 1965-01-27
Abstract: 1,102,062. Automatic moisture control. H. MAHLO. Jan.27, 1965 [Feb. 3, 1964], No. 3540/65. Heading G3R. In a system for automatically controlling the moisture content of moving material, follow-up controlled means regulating the moisture content are controlled by intermediate error-actuated means having a response characteristic such as to produce a desired overall response characteristic. As shown, a signal dependent on the moisture content of moving textile material T is compared at 2 with a signal representing desired moisture content, and any difference causes a motor 3 to adjust to position of a potentiometer 4 having an exponential characteristic. The output voltage of potentiometer 4 is compared at 5 with the voltage of a tachometer generator 6 associated with a motor 8, and any difference is effective through a controller 7 to adjust the speed of motor 8 to correspond with the position of potentiometer 4. Motor 8 drives the textile material and its speed is changed in such sense as to correct the moisture content. The time constant of the system controlling motor 3 is longer than that controlling motor 8 and potentiometer 4 serves as a memory to maintain the speed of motor 8, if the moisture measuring section should fail, until a timer 10 resets potentiometer 4. Correction of moisture content by control of the temperature of a drying agent or by varying the flow of material, air or water instead of varying speed is referred to. Use of a mechanical or fluid-pressure link to the final control element is also referred to.

Title: Improvements in and relating to the activation of platinum group metals
IPC: C25B11/00
Filed: 1963-01-30
Abstract: The surface of a metal of the platinum group is made active for use, for example, as an electrode in the electrolysis of brine, by coating the surface with mercury, and then heating at 500 -900  DEG F. to drive off the mercury.  The coating may be formed by electro-deposition, vapour deposition, or preferably by treating with an alkali metal amalgam, and then immersing in water to remove the alkali metal, and heating. The platinum metal surface may be pre-treated by the process described in Specification 918,328, i.e. treating with H and heating whereby some recrystallization of the Pt metal is effected.  Tables are given showing the reduction in over-voltage in brine cells using electrodes made by treating Pt metals, e.g. plated on titanium. Reference is made to treating platinum in fabricated form, e.g. powder, alloys of platinum with other metals of the platinum groups and with silver.  Specification 897,690 also is referred to.

Specified peroxides include hydroperoxides, dialkyl and diaralkyl peroxides, peroxy acids, peroxy esters, diacyl peroxides and peroxy derivatives of aldehydes and ketones.  The peroxide catalyst may be used in amounts not more than 10%, based on the aluminium.  Sodium, lithium, potassium, magnesium, calcium or other Group I (a) or II (a) metal may be used as an additional catalyst in amount from 0.1% to 5% based on the weight of the aluminium.

Abstract: 566,145. Control systems for incandescent lamps and bells. HORSFORD, M. A. March 9, 1943, No. 3830. [Class 38 (iv)] [Also in Groups XXXVII and XXXVIII] An audible warning system is combined with an illumination system, the latter being controlled by a delayed action device so that the illumination is maintained for a certain time after the audible warning ceases. A press-button switch 8 has two groups of contacts 11 ... 13 and 14, 15, the first group closing the circuit of a lamp 20 and the second group closing the circuit of a bell or buzzer 1. When the button is pressed in, a catch 25 engages behind a shoulder 26, so that on releasing the button the bell circuit contacts 14, 15 are allowed to open, but further outward movement of the button is prevented and the contacts 11 ... 13 remain closed. The lamp 20 thus remains alight until a heater 19 supplied through the contacts 12, 13 causes a bimetallic strip 23 to bend and disengage the catch 25. An indicator lamp 22 may be included in the illumination circuit and a switch 21 for hand control of the lamp 20 may be provided.

As shown in Fig. 6 the sections a are attached to a foot d slidable on the bottom f of the container and are connected to the bottom of the tank by an upwardly arched plate member g. In a modification the webs are directed radially inwards and the ties attached thereto lie within the shell. As shown in Fig. 5 the foot d then slides on a foundation ring below the bottom of the container and the shell is attached to the bottom f by a downwardly arched plate g.
