Filed: 1937-01-22
Abstract: 474,193. Alternating current commutator motors. STALDER, M. Jan. 22, 1937, No. 2018. Convention date, Jan. 23, 1936. [Class 35] In a motor of the type which runs as a repulsion-motor up to a certain speed, the rotor being then short-circuited so that it runs as an induction-motor, the brushes and brush-lifting gear are replaced by mercuryswitching arrangements. For this purpose a number of hollow cylindrical bodies are arranged on the rotor shaft and each such body is provided with such a number of equally spaced contacts that the angle between two connecting contacts on the same cylindrical body is equal to the brush angle of an ordinary motor. The Figure shows an arrangement for a four-pole machine with twenty-eight rotor bars, so that there are seven hollow bodies and each one has four of the contacts K<1>, K<8> .. .... K<16> ; two consecutive contacts K<1>, K<8> on one of the bodies being 90‹ apart. The angle between a contact K<8> on one of the bodies and the consecutive contact K<9> on the next body is <1>/28 of the circumference. Each of the hollow bodies contains a quantiy of mercury sufficient to short-circuit two of the contacts when the mercury is collected at the bottom of the body, but when the machine attains a certain speed the mercury is distributed round the circumference of the cylinder and all the contacts are short circuited. The effect of shifting the brushes in an ordinary motor can be obtained by displacing the switching arrangement angularly with respect to the rotor.

Convention dates, Feb. 7, 1939. and Dec. 2, 1939. Addition to 537,976. [Class 2 (iii)] Compounds of the general formula where R is hydrogen alkyl or aralkyl and X is alkyl or alkoxy are treated with alkyl magnesium halides to give alcohols of the formula where R 1  and R 2  are similar or different alkyl groups, which are then subjected to the action of de-hydrating agents. The de-hydration is preferably effected by means of a phosphorus halide followed by boiling in toluene which causes substantial radical migration. The products which are stilbene derivatives may if desired be des-alkylated by hydrolysis with alcoholic caustic alkali at elevated temperature to produce a strongly oestrogenic compound. In examples : (1) Di-p-anisyl-acetic acid is esterified with ethyl alcohol and then treated in ether solution with magnesium ethyl bromide to give 2:2<SP>1</SP>-di-p-anisyl-1:1-diethyl-ethanol. This compound is de-hydrated by treatment with phosphorus oxychloride followed by boiling in toluene to form α-α<SP>1</SP>-diethyl stilbene, and α-α<SP>1</SP>- dianisyl-#-#<SP>1</SP>-diethyl ethylene. (2) 1:1-dianisyl butanone-2 prepared by refluxing α-α<SP>1</SP>-dianisyl- α-ethyl ethylene glycol with oxalic acid in acetic acid solution is treated with ethyl magnesium bromide to give an ethanol derivative identical with that prepared by the same process from chloro-desoxy-anisoin.

Title: Method for hardening lime and like plaster and mortar
IPC: C04B40/02
Filed: 1944-02-07
Abstract: Articles such as wall plates, tiles, statuary and the like constructed from plaster containing burnt or slaked lime, magnesia or other material capable of hardening under the action of carbon dioxide, and containing, if desired, inorganic or organic fillers such as sand, sawdust, hair or fibre, are formed and placed as a diaphragm between two compartments during the hardening-process, one compartment concontaining a moist atmosphere rich in carbon dioxide, while the other contains a relatively dry atmosphere to cause evaporation of water from the face of the article in contact therewith.  The pressure of the relatively dry atmosphere is lower than that of the atmosphere containing carbon dioxide, so that there is a tendency for the carbon dioxide to be drawn through the article and complete the hardening process; further, the presence of a moist atmosphere on the one side retards evaporation of the water in the article and so prevents the formation of a hardened crust before the lime &c. is completely reacted.  The articles are moulded from a composition containing just insufficient water to trickle from the moulded articles and they are cast in a mould with a foraminous bottom which is placed over an aperture in a partition dividing a chamber into two compartments.  The lower compartment contains water through which carbon dioxide or flue gases can be bubbled, while the upper compartment is provided with means for drawing off the evaporated water and for heating or drying the contained air. Alternatively, the moulds may be mounted on a conveyer travelling through the chamber, or the plaster can be applied as a continuous sheet to such a conveyer formed of permeable material such as metal wire netting.  If desired, a layer of fibrous material may be placed at the bottom of the mould or under the sheet on the conveyer to become secured to the plaster on setting, and a similar layer can be placed above the article.  To increase the bonding between the layer and the article, the layer may be first soaked with lime water or the like before application.  Inner reinforcements may also be incorporated.  When applying the plaster to a wall, a mat of thin perforated pipes is applied to the face of the wall, the perforations being directed towards the wall and the pipes being supplied with moist carbon dioxide.  The plaster is applied to the pipes, and a space constructed over the plaster layer with tarpaulins or the like through which dried and heated air can be drawn.
