Abstract: 189.982. Massolle. J., Vogt, H., and Engl. J. Nov. 23, 1921. Condenser telephones and other electrostatic instruments. - In electrostatic telephones all parts determining the distance between the electrodes are made of metal except for thin discs of insulating material firmly clamped between the metal parts. One condenser electrode p, Fig. 1, is screwed into supporting plates g of metal and the diaphragm m clamped between insulating rings i<1>, i<2>. The clamping ring k is secured to the plates g by screws sch and a discharging ring a is clamped against the diaphragm by a tensioning ring sp of ebonite. An abutment ring w is preferably provided for ensuring spring between the electrode p and diaphragm m. The diaphragm may be of metal foil or of insulating material with a conducting layer on both sides. In modifications the conducting layer may be upon one side only and may be only of the same size as the ring a. The tension on the diaphragm is determined by the difference in height between the parts g, w but these may be of the same height and the diaphragm inserted in a state of tension. The construction may be applied to a differential instrument. The diaphragm may be fixed at the centre r<0>, Fig. 10, and there may be subdividing rings r<1>, r<2> against which the diaphragm is pressed. In this case the electrodes b<1>, b<2>, may be made concave. The diaphragm may be made of mica, glass, paper, or gold-beater's skin. and the conducting coating be applied by electrodeposition, by chloride of platinum, by means of graphite, cathode dispersion, or by cementing.

Title: Method of testing coins and device for carrying out same method
IPC: G07D5/08
Filed: 1934-11-07
Abstract: 451,694. Testing coins; inductances. ROTH, W., 21, Langgasstrasse, Berne, Switzerland. Nov. 7, 1934, Nos. 32020 and 32021. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 9, 1935]. [Class 37] [See also Groups XVIII, II, and XL] In coin-testing mechanism, e.g. for coinfreed apparatus, a coin to be tested is subjected to an alternating magnetic field produced by a thermionic valve oscillator, and the change in frequency of the oscillator due to the eddy currents created in the coin is compared with that similarly produced in the same or a similar oscillator by a standard coin. In Fig. 1, the grid circuit L1C1 of an oscillating valve V1 is coupled with the oscillatory grid circuit L2C2 of an anode rectifying valve V2 having a relay R in its anode circuit. An inserted coin is retained adjacent to the inductance L1 so that the induced eddy currents influence the frequency of oscillation. Normally L2C2 does not resonate with .L1C1, and the anode current of the valve V2 is insufficient to cause operation of the relay, but a supplementary condenser C<1>1 is previously adjusted with an inserted standard coin, so that, with a sufficiently similar coin L1C1 oscillates at the resonant frequency of L2C2 and the relay R responds to deliver the coin into an appropriate channel. In a modification the valve V2 is set oscillating at a frequency slightly different from valve V1, and a vibratory relay responsive to the beat frequency of the two circuits is inserted at R. The apparatus is previously set so that the beat frequency causes the relay to respond if the coin is up to standard. In Fig. 3, the oscillations of valves V1 and V2 are applied to the grid and cathode respectively of a valve V3 by inductances L3 and L4. Standard coins are contained in a drum MTr which can be set so as to bring the required coin into proximity with the inductance L2 of the valve V2, and inserted coins are retained adjacent the inductance L1 of the valve V1. A condenser C<1>1 associated with the valve V1 is previously adjusted so that if the inserted coin is sufficiently like the standard coin the valves V1 and V2 oscillate at the same frequency and in phase with one another, so that the potential between the grid and cathode of the valve V3 is reduced to zero, a relay R in the anode circuit of the valve V3 responding under such conditions. By increasing the frequency of oscillation in any of the above apparatus, the eddy currents tend to keep to the surface of the coins, so that the influence of the embossment of the coin on the response of the relay is increased. In order to nullify the influence of small variations in diameter of the coins, metal screens may be provided to mask their edges, or the inductance L1 may be constructed so that the edge of the coin lies between its inner and outer circumferences. Alternatively, a ferromagnetic powder core may concentrate the field of the inductance L1 at the centre of the coin.

Title: Process of preparing dialkyl substituted aromatic compounds
IPC: C07C2/66
Filed: 1959-09-21
Abstract: Dialkyl substituted aromatic compounds are prepared by reacting an alkylatable aromatic compound containing no more than one alkyl substituent with an alkylating agent in the presence of a solid catalyst containing a major proportion of alumina and a minor proportion of boria.  The alkylatable compound may be a hydrocarbon preferably containing one alkyl substituent having up to 18 carbon atoms in the alkyl group, many derivatives of benzene, naphthalene, anthracene, phenanthrene and indene being specified, or an aromatic amine, halogen compound, ketone, a salt of a phenol or a salt of an aromatic carboxylic acid.  The alkylating agent may be an aliphatic olefine of up to 18 carbon atoms, a cycloolefine or a polyolefine such as butadiene or isoprene.  The ratio of unsubstituted aromatic to olefine is 1 : 1 to 2 : 1 and of alkylated aromatic to olefine 4 : 1 to 10 : 1 using temperatures of 100-350 DEG C. and pressures of 1-100 atmospheres in liquid or vapour phase.  In continuous processes using fixed or moving beds of catalysts a liquid hourly space velocity of 0,1-20 is used.  The catalyst may contain 5-35% by weight of boria.  High yields of para-dialkyl substituted compounds are obtained.  In the Examples (1) cumene and propylene yield di-isopropylbenzenes, (4) toluene and propylene yield cymenes.
