Abstract: 1,240,890. Determining weight electrically. VDO LUFTFAHRTGERATE WERK ADOLF SCHINDLING G. m. b. H. Dec.6, 1968, No. 58145/68. Heading G1N. [Also in Division G4] In apparatus for determining the position of the centre of gravity and/or weight of an aircraft supported by its three wheels, a load gauge is provided at each support for converting the load at each support into a respective resistance, the resistances being provided in an analogue circuit. The circuit includes a negative feedback operational amplifier provided with an input resistance and a feedback resistance, which resistances are determined by the value of the resistances given by the load gauges. As shown, the centre of gravity is G 1  and the distance l 3  may be determined by using an analogue circuit in which the feedback resistance R H   2  is given by a load potentiometer at one of the main landing wheels, and the input resistance R H1  + R H2  is given by the series of another load potentiometer at this landing wheel and a load potentiometer at the other main landing wheel. The output voltage U l3  is then proportional to the distance l 3  for a fixed input voltage Ul 4  which is proportional to l 4 , as can be seen by comparison with the corresponding "moments of force" diagram in Fig.5. In a similar manner, the distance l 1  may be determined, Fig.4 (not shown). The total weight of the aircraft is determined by using a series of three load potentiometers i.e. one at each of the wheels, as the feedback resistance, the input resistance being a fixed resistor R. The position of the centre of gravity may be determined from any suitable point of reference. The two measurements of the position of the centre of gravity and the measurement of the total weight may be carried out simultaneously by using three amplifiers and the appropriate number of load gauges or may be carried out consecutively using one amplifier and a relay or electronic switch.

Title: Process for the production of diazotype intermediate originals
IPC: G03C11/00
Filed: 1969-12-08
Abstract: 1286552 Photographic processes KALLE A G 8 Dec 1969 [10 Dec 1968] 59713/69 Heading G2C A process for producing azo dye images comprises imagewise exposing a positive working material containing a benzene diazonium compound having, in the ortho or para position to the diazonium group, a secondary or tertiary amino group having as substitment(s), alkyl, cycloalkyl or aralkyl radical(s) or a radical forming a heterocyclic ring with the N atom of amino group, and developing in the presence of a coupler which either contains an active methylene group or is a phenol containing no amino nitrogen atom attached to the benzene nucleus to produce a yellow dye image and then subjecting the image to an electrophilic reactant to shift the maximum absorption of the dye into the ultraviolet. The electrophilic reactant may be (i) a strong acid, e.g. HCl used in solution or as a vapour or generated by photolysis of organic halogens, or (ii) diazonium salts which generate acids and carbonium ions on photo-lysis. In the examples, a support is coated with a layer of a benzene diazonium compound containing a dialkylamine or heterocyclic group with the nitrogen atom attached to the benzene ring, a coupler which is an acetoacetyl compound, a phrazolone, resorcinol, phloroglucinol, or an alkyl phenol and optionally a hydroxynaphltamide or a hydroxyphenyl area, imagewise exposed and developed to give a dye image with an absorption maximum between 402 and 480 mm. The image is treated with hydrochloric acid to give an image with an absorption maximum between 363 and 390 mm. If a diazonium compound or a coupler which does not contain the specified groups if present, the azo dye image produced by this component is unaffected by the acid and the final image has two absorption maxima. Hydrochloric acid may be replaced by an organic halogen which is light-sensitive and is present either in the diazonium layer or a layer on the back of the support (if this is porous) and after imagewise exposure and development a second uniform exposure produces images with an absorption maximum in the ultraviolet. Alternatively, either a diazonium compound may be applied after development or excess diazonium compound may be added before imagewise exposure so that a uniform exposure after development produces an image with the desired absorption maximum. The images produced are used as originals for diazotype materials.

Title: Control circuits for dc electric rotating machines
IPC: H02P1/20
Filed: 1971-12-29
Abstract: 1379040 Controlling starting of a DC motor HITACHI Ltd 29 Dec 1971 [29 Dec 1970] 60375/71 Heading H2J A D.C.-motor starting circuit includes series connected, different valued starting resistors, shunted in a predetermined order to keep the motor armature current between preset limits, and a variable resistor including a current chopper, whose effective resistance immediately prior to the shunting of each starting resistor is set to the value of that resistor. In an embodiment, the starting of an electric train, having a D.C. motor 4 which is connected through a circuit-breaker (not shown) and pantograph 2 to an overhead power supply 1, is controlled by shunting starting resistors, 5 to 10, each of different values, by closing switches 11 to 16 by controller 21. This controller also varies the current in a current chopper 81, forming part of the variable resistance 17, that also includes a switch 20 and resistor 19, which is at least as large as the largest starting resistor. Upon starting, the resistors 5 to 10 and 19 are_in circuit and chopper 18 is not conducting. Speed is increased by increasing the conduction period of the chopper 18 until resistor 19 is at least partially short circuited and a minimum armature current (Io, Fig. 5, not shown), is detected. Then the chopper conduction period is reduced so that the variable resistance is equal to the starting resistor 5 to be shunted, the armature current rising smoothly, in a short time such that the motor speed does not increase, until the armature maximum current (Ic) is reached, then switch 11 is closed by controller 21 to shunt resistor 5, the chopper conduction being simultaneously reduced to zero. The chopper conduction is then increased to repeat the cycle for each starting resistor, until, at full speed, resistors 5 to 10 and 19 have been shunted by switches 11 to 16 and 20 respectively. Thus the armature current range is limited to a minimum (Io) and a maximum (Ic), which may be the maximum permissible armature current, allowing the minimum number of starting resistors, and overshoot when shunting the starting resistors is avoided. The switches 11 to 16 may be solenoid operated or SCR switches, and the variable resistance 17 could comprise further switchable resistors in parallel with resistor 19, Fig. 2 (not shown).
