Abstract: 471,707. Roadtraffic signals on vehicles. CARELLO, F., and CARELLO, P., (trading as CARELLO FRATELLI, F. & P.). Nov. 16, 1936, No. 31304. [Class 118 (ii)] The operating magnet of an electrically operated semaphore arm is situated remote from the arm, the solenoid core and the arm being connected by a Bowden wire serving also as the electric lead for the lamp carried by the arm. The solenoid 12 is mounted on the dashboard of a car and when operated the armature 11 moves against the action of the restoring spring 15 which is sufficiently strong to hold the arm in its casing in the normal condition of the apparatus. When the armature 11 moves it pulls the wire 8 through its casing 9 and raises the arm 4 into the signalling position. A lamp 5 within the arm is energized in the operated position of the arm, the circuit passing through the wire 8 and being completed when the solenoid is energized by contact 17 on the core 11 touching the contact member 18. The tube in which the armature core moves and the casing 9 of the Bowden wire must be of insulating-material. The lamp 5 may be removed from the arm for replacement by springing open the upper side of the arm which is normally held down by spring 24 and by its own elasticity at its fixed end.

Title: Process for the manufacture of tertiary alcohols of the cyclopentano polyhydro phenanthrene series
Filed: 1936-11-23
Abstract: Tertiary alcohols of the cyclopentanopoly-hydrophenanthrene series are prepared by the interaction of acetylene or a substituted acetylene on saturated or unsaturated compounds of the cyclopentanopolyhydrophenanthrene series which contain a keto group in their cyclopentano nucleus.  The reaction is conducted in the presence of alkali metals or alkali metal compounds such as alkali amides or alcoholates.  Compounds mentioned which may be submitted to the process of the present invention are the follicle hormones, oestrone, equiline and equilenine, and the male sex hormones androsterone and dehydroandrosterone.  In the case of oestrone the reaction product has the constitution <FORM:0468123/IV/1> The ethinyl compounds formed may be hydrogenated either to fully saturated compounds or to compounds of an intermediate degree of saturation. When substituted acetylenes are used, tertiary alcohols with a correspondingly longer side chain are obtained. In examples: (1) An ether solution of follicle hormoneacetate is reacted with sodamide and acetylene passed in until no further absorption takes place.  The reaction product on decomposition with water yields ethinyl dihydro-follicle hormone acetate, which can be hydrogenated in the presence of a platinum catalyst to ethyl dihydrofollicle hormone acetate; (2) Androsterone is treated according to the process of example (1) to yield on hydrogenation ethyl androstandiol.  Samples have been furnished under Sect. 2 (5) of ethinyl androstendiol monoacetate made (1) by passing acetylene into a benzene solution of dehydroandrosterone acetate in the presence of sodamide for about 42 hours.  The reaction product is decomposed with water and the crude product purified by its silver salt, (2) by passing acetylene into a benzene solution of androstenolone acetate in the presence of sodamide.  The reaction product is decomposed with weak acid, and the unchanged androstenolone acetate recovered by transformation into its semicarbazide, to give as a residue the required product.

Abstract: 466,124. Valve circuits for wireless reception. RADIOAKT.-GES. D. S. LOEWE. Nov. 21, 1935, No. 32285. Convention date, Nov. 24, 1934. [Class 40 (v)] In a short-wave receiver, particularly a superheterodyne receiver for television, electrodes or other elements which are intended to be at zero radio-frequency potential are connected immediately to earth by a condenser which with the unavoidable inductance of the leads forms a circuit with a natural frequency higher than the operating frequency. The screen 3, Fig. 1, of a mixing-valve V1 is connected to H.T. supply in the usual manner through a resistance 8 with a capacity shunt 6 to earth. On account of the inherent inductance, indicated at 9, of the lead, this does not effectively earth the screen nor prevent it from carrying a radio-frequency voltage relatively to the cathode K. The screen 3 is therefore connected to the cathode by a condenser 17 adjacent to or within the valve, and of capacity of 100-500 mmf. A series resistance 16 is connected in the supply lead close to the connection point 20 of the condenser or the lead is formed of resistance wire. Similar combinations of condenser 21 and resistance 22 are provided in the grid-bias lead to the input grid 2, and in the grid input circuit of a following valve V2. The resistance 16 may be housed within the condenser 17 in the manner indicated in Fig. 2.
