Title: An automatic weighing apparatus
IPC: G01G13/00
Filed: 1960-10-20
Abstract: 966,700. Weighing devices. T. TARUKAWA. Oct. 20, 1960 [Oct. 31, 1959; March 23, 1960], No. 36036/60. Heading G1W. A weighing apparatus comprises a weighing tank having a main discharge opening and an auxiliary discharge device operable to discharge excess material from the tank. In the event of an overcharge of material the beam W1 of the weighing device rises to allow a light beam from an electric lamp L1 to impinge upon a photo-electric cell L3 which operates a relay R to open a circuit to an electro magnetic switch MgSF to stop the charging motor and energizes a switch MgSD<1> to rotate a reversible motor in a direction to drive an impeller to discharge excess material down a conduit. At the predetermined weight of the material the beam descends to shut off the light beam, the relay R is energized to operate the electro magnet MgC to switch over switch SC. Time limit switch TCD operates to energize electromagnet MgD to pivot a lever to release a clutch on the shaft to allow the discharge door to open. At the end of discharge the time limit switch opens and the clutch re-engages. The circuit may be designed so that pressing switch PS initiates discharge. By inserting a time limit switch TCC between the electromagnet MgC<1> and switch SC and a press switch PS<1> in series with the electromagnet MgC<1> automatic reweighing takes place. The light beam may be reflected from the upper surface of the weighing beam. The beam may support an electrode which moves to and from a stationary electrode to vary the capacity as a tuning circuit of an oscillator using an electron tube or transistor and a relay R in the photocircuit. In other modifications an iron core attached to the beam may move in a transformer connected to an amplifier and relay R. An iron core on the balance beam may approach the coil on a movable iron core in series with a resonant circuit the output being rectified to operate a relay. The apparatus may be adapted to weigh liquids, the tank and auxiliary discharge tube being suspended by cable from the weighing beam and valves under control of electromagnetic devices provided for supplying and discharging the liquid.

Title: Dextro- and laevo-rotatory 5-(3-dimethylamino-2-methylpropyl)iminodibenzyl
Inventor: JACOB ROBERT MICHEL
IPC: C07D223/28
Filed: 1959-10-27
Abstract: The invention comprises dextrorotatory and laevorotatory 5-(3-dimethylamino - 2 - methylpropyl)-iminodibenzyl, their pharmaceutically acceptable salts, their production (1) by reaction of dimethylamine with an enantiomorph of a compound of formula <FORM:0900352/IV (b)/1> wherein Z represents a reactive ester group and (2) by resolution of the racemic form of the required compound by diastereoisomeric salt formation with an optically active acid (e.g. di-(p-toluyl)-D-tartaric acid), and pharmaceutical compositions containing the foregoing compounds.  5-(d,l-3-hydroxy - 2 - methylpropyl)iminodibenzyl is converted into its phthalic acid half-ester by heating under reflux with phthalic anhydride in toluene.  This half-ester is resolved by crystallisation of its strychnine salt, from which the required enantiomorph is liberated with hydrochloric acid.  Hydrolysis of the resolved half-ester gives the d or l form of 5-(3-hydroxy - 2 - methylpropyl)iminodibenzyl, which is esterified with toluene-p-sulphonyl chloride in the presence of pyridine to give d- or l-5-(3-toluene-p-sulphonyloxy-2-methylpropyl)-iminodibenzyl, a reactive ester used for process (1) above.  Pharmaceutical compositions containing the laevo base or its pharmaceutically acceptable acid-addition salts are sedatives, while those containing the corresponding dextro compounds are neurotonic agents.  They may be in forms suitable for oral or parenteral administration, e.g. tablets, pills, dispersible powders, granules, emulsions, solutions, suspensions, syrups, elixir or capsules.  Specification 668,659 is referred to.

Abstract: 980,706. Printed circuits; inductors; electrodes for capacitors. PHOTOCIRCUITS CORPORATION. Oct. 17, 1961 [Nov. 3, 1960], No. 37145/61. Headings H1R and H1T. [Also in Division H2] A process for producing a printed circuit includes the steps of partially forming the conductors so as to leave a residual conductive web for supporting the conductors and finally etching away the web structure to leave the conductors. As described the process is applied to the production of a motor rotor comprising a plurality of radial conductive segments 12, 12<SP>1</SP> arranged adjacent to one another, each of the segments including external terminal sections 13, 13<SP>1</SP> and internal terminal sections 14, 14<SP>1</SP> provided with holes 23, 23<SP>1</SP> and 24, 24<SP>1</SP>, respectively. A blank of sheet metal is stamped in a press so as to form the conductive segments 12, 12<SP>1</SP> and non-conducting regions 15 between them, the die only cutting part of the way through the sheet so as to leave a residual web 18 interconnecting the conductive segments. Two rotor discs thus formed are then placed with their faces opposing against opposite sides of an insulator 20, the grooves 15 between the conductors 12, 12<SP>1</SP> being in the interior adjacent the insulator 20. The assembly is then etched until the residual web 18 has been dissolved and each conductor 12 is separated and insulated from adjacent conductors 12<SP>1</SP>. Plated through holes 23, 23<SP>1</SP>, 24, 241 interconnect the conductors on opposite sides of the insulating material. In some cases the residual web is etched away prior to permanent assembly to the insulator, in which case the impressed pattern is temporarily mounted and pressed face downwards on a pressure-sensitive sheet in order to provide means for maintaining the conductive segments in position after removal of the residual web portion. To eliminate undercutting of the grooves before the residual web has been completely removed an etch resist may be sprayed on to the impressed face of the circuit configuration. In another embodiment the web section 18 may alternatively be mounted adjacent the insulator 20 and then removed by etching, Fig. 8 (not shown). The invention may be applied to the production of inductors and capacitor plates. Specification 874,394 is referred to.
Patent GB-1001445-A (GB)
Title: Antipolorization membrane, system and method
IPC: C08J5/22
Filed: 1961-10-17
Abstract: In the electrodialysis of solutions, especially very dilute solutions, polarization of the permeable diaphragm is largely prevented by using a mixture of cationic and anionic exchange resins to form the permeable diaphragm, in such proportions that the total membrane conductance for ions of one polarity exceeds that of the oppositely charged ions.  By this means higher current densities are achieved.  The conductance ratio between "pol" and "depol" ions is independent of ionic mobility of the ions concerned, and the depolarizing action depends on ratio of the conductance of the two types of ion, the pH of the liquid, and the mobility of the ions.  An apparatus is described in which the conductance ratios may be determined consisting of a cell divided by membranes of the anion resin, cation resin, and also of the blended mixture, conductivity measuring bridges being mounted in the compartments of the cell which is fed with a standard salt solution. Air agitation is applied. Suitable resin combinations are: sulphonated and quaternized ionogenic compounds, e.g. polystyrene sulphonate butyl ester, and quaternized polystyrene propionate.  Thermoplastic resins may also be used.  The membranes are formed of a random mixture, heated, and moulded under pressure, or by forming a viscous solution of resins together with a matrix support and a little catalyst, e.g. dimethyl formamide or dimethyl sulphoxide, which is then moulded, dried and preferably irradiated with U.V.  As matrix supports there may be used vinyl chloride/ acrylonitrile polymer, polystyrene, polyethylene, or polyethylene/polystyrene graft-polymer.  A table is given of a range of resin mixtures, and of tests with 0.1 N solutions of HCl, NaOH, and NaCl, of pH range 1.1-13.
