Patent GB-668659-A (GB)
Title: Improvements in and relating to basic derivatives of imino dibenzyl compounds
Filed: 1949-11-19
Abstract: The Specification comprises basic derivatives of imino dibenzyl having the general formula <FORM:0668659/IV (b)/1> wherein Alkylene is an alkylene chain of 2 to 6 carbon atoms having attached thereto in b -, g -, or d -position the group Am which represents a dialkylamino radical (alkyl containing from 1 to 4 carbon atoms) or an N-piperidino, N-morpholino or N-pyrrolidino radical, and salts and quaternary ammonium compounds thereof.  The bases are prepared by reacting imino dibenzyl with a reactive ester of an alcohol HO-Alkylene-Am in presence of an acid binding agent, e.g. sodium, lithium or potassium amides or sodium or potassium metal.  Suitable reactive esters are dimethylamino -, diethylamino -, methylethylamino -, piperidino-, pyrrolidino-, or morpholino ethyl chloride, b -dimethylamino propyl or isopropyl chloride, g -dimethylamino propyl chloride, a -methyl-d -dimethylamino pentyl chloride, di-n-propylamino ethyl chloride, methyl isopropylamino ethyl chloride, di-isobutylamino ethyl chloride, di-n-butylamino ethyl chloride or the corresponding bromides or iodides.  Alternatively imino dibenzyl is reacted with a mono-or di-ester, e.g. aryl sulphonic acid ester of a glycol of the general formula HO-Alkylene-OH in the presence of an acid binding agent, and if a mono-ester has been used, the hydroxyl group is converted to a reactive ester group.  The reactive ester of N-(hydroxyalkyl)-imino dibenzyl obtained is then reacted with a secondary amine Am-H to form the base, or with a tertiary amine R-Am where R is alkyl or aralkyl, to yield the corresponding quaternary ammonium compounds.  The latter may also be made by reacting the tertiary bases by reaction with halides or sulphates of aliphatic or araliphatic alcohols.  Salts of the tertiary bases may be made with hydrochloric, hydrobromic, sulphuric, phosphoric, methane sulphonic, ethane disulphonic, acetic, citric, malic, succinic, tartaric, benzoic or phthalic acids.  In examples there are prepared (1) N-b -dimethylaminopropyl iminodibenzyl by reacting iminodibenzyl and b -dimethylamino isopropyl chloride in presence of sodamide; (2) N-piperidino ethyl imino dibenzyl similarly.

Abstract: 629,611. Collapsable cores for moulding hollow concrete units. MATTHEWS & MUMBY, Ltd., and KEMPSHALL, H. A. Oct. 5, 1946, No. 29737. [Class 87 (ii)] A collapsable core comprises a longitudinal ridge or key-piece g of inverted T section, the sides of the stem of the T being tapered, and two side members c of approximately D shape, the upper portions of which are shaped to engage the tapered sides of the key-piece and the lower outer portions being radiused at d. Plates h secured to the arms of the T of the key-piece project upwardly to form channels in which engage downwardly projecting plates f attached to the upper side faces of the side members. To make a hollow block the core is erected on partially cured concrete b, cast in the bottom of a mould a, by supporting the key-piece g at its ends which project beyond the ends of the mould and then placing the side members in position. Concrete is then cast around the core and after setting the supports of the key-piece are removed whereupon the key-piece drops or may be pulled down to free the side members c which can then be pivoted at d and removed. Two cores end to end may be used for a long concrete unit, the adjacent ends of the key-pieces then being shaped to rest on the curved face of a semicylindrical block placed transversely in the centre of the mould. After removing the outer support of a key piece the outer end of the key piece is lowered and a short longitudinal movement releases it from the centre support.

Abstract: 176,052. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 27, 1920. Scents for continuous-current motors; control by regulating field.-In controlling motors according to the Ward-Leonard system, the generator is separately excited by a machine of substantially constant voltage, and the motor field is excited by the generator and the excited machine in series. Variations of speed are obtained by varying resistance in the fields of the generator and motor simultaneously and in opposite senses. One arrangement is shown in Figs. 1 and 2. A motor 10 is supplied by a generator 11, the generator field 13 being excited by a separate constant voltage machine 14, and the motor field 12 being excited by the machine 11 and 14 in series. Resistances R<1>, R<2> connected to the generator field and R<3>, R<4> connected to the motor field are grouped into one instrument so that by rotating a double contact-arm 19, Fig. 1, resistance is added to the generator field and simultaneously subtracted from the motor field or vice versa. The continued movement of the contact-arm on passing off a stud 23 transfers the motor excitation to the generator alone, without breaking the field circuit.
