Abstract: The invention comprises compounds of the general formula: <FORM:0952958/C2/1> (wherein R represents a C1-6 alkyl group) and acid addition salts thereof, pharmaceutical preparations containing them (in which case the salts are physiologically tolerable), and their preparation by (a) condensing a compound of the general formula: <FORM:0952958/C2/2> (wherein X represents a halogen atom) with tetrahydrofurfurylamine, or (b) reducing the furan ring in a compound of the general formula: <FORM:0952958/C2/3> optionally followed by salt formation in either case.  N-[b -(O-methoxyphenoxy) - ethyl] - furfurylamine is prepared by condensing o-methoxyphenoxyethyl chloride with furfurylamine; its hydrochloride is described.  The compounds of the invention are sedatives and may be administered enterally or parenterally to human beings and animals in the form of pharmaceutical preparations (e.g. tablets, dragees, solutions, suspensions and emulsions) containing them, with or without other (unspecified) therapeutically active substances, in admixture or conjunction with an excipient.  The compounds may also be added to animal fodder. The acid addition salts may be derived from an inorganic or organic acid, including ascorbic, salicylic and 4-aminosalicylic acids.

Title: Improvements in and relating to formers for hats, caps and the like
IPC: A42C1/04
Filed: 1928-06-11
Abstract: 292,089. Mourlan, G. M. June 9,1927, [Convention date]. Blocking. - In a hydraulic blocking machine, the usual rubber bag is replaced by an easily interchangeable bag mounted on an elastic membrane, means being provided for preventing entry of air or escape of water from behind the membrane during the changing of the bag. The usual dome b with water connection f co-operates with a rubber membrane a with a central aperture in which a headed sleeve p is secured by a nut q. A cap s perforated at t is screwed down upon the sleeve p end houses a spring v' pressing a ball v towards a seating on the upper end of the sleeve p. The interchangeable bag h carries a headed sleeve m screw-threaded to engage the sleeve p, perforated at its upper end, and so long as normally to raise the ball v from the seat p<3>. When it is desired to exchange a bag, unscrewing the sleeve m from the sleeve p allows the ball to seat and close the passage leading to the bag. The bag desired is then positioned, with consequent raising of the ball by its sleeve m. Rubber washers x, y minimize injury to the rubber membranes.

Abstract: 583,008. Flexible tube pumps. WALKER' H. J. BELL-, HIBBERT, D. M. (Representatives of WALKER, C. BELL-), and WARDMAN, C. B. Sept. 5, 1944, No. 16967. [Class 110 (ii)] A flexible member 18 is pressed into helical grooves 40 by an eccentric 32, on a shaft 34, acting through a conical member 28, to pump fluid from an inlet 42 to a delivery 44, and/or 52. A number of grooves may be arranged parallel to each other. To vary the pump capacity, the member 28 is moved axially when a gearwheel 46 is rotated. This meshes with teeth 44 on a bush 38 which is rotated and moves axially through screw action with threads 14. A further adjustment is arranged by elongating the holes 50 in the cover 12 through which pass studs 24. Fig. 4 shows a modification having inlet and outlet points 42, 52, and includes a mushroom-shaped bush 58 with an axial bore 60 leading to a lower chamber enclosed by a cap 59. The bush 58 secures the bottom wall of the member 18 and may be adjusted, by means of its thread, to alter the pre-determined blow-off pressure which deforms the member 18 allowing fluid to return to the section. The member 28 may be made of any non-metallic material, and may be of a self-lubricating anti-friction nature. The numbers of inlets and deliveries may differ from each other. Grooves may be arranged on each side of the member 18.

Abstract: 982,260. Lift control systems. J. E. MAGEE. May 7, 1962 [May 12, 1961], No. 17392/62. Drawings to Specification. Heading B8L. A control system for a lift car operating in a down peak traffic condition is provided with means for detecting and memorizing the existence of one or more registered down landing calls which have been by-passed by the descending car or which have been unanswered for more than a predetermined length of time, and with means for dispatching a car from the dispatching floor to the floor most remote from the dispatching floor having such a registered down landing call. In the described embodiment, in a control system for at least three lift cars, means are provided for each car for detecting when each registered down landing call is by-passed by that car and the calls for each landing are memorized on a group basis. A predetermined number of such remembered by-passed calls causes transfer of a car to down-peak operation wherein it is dispatched to the highest such call. Persistence of remembered by-passed calls for a predetermined period or the existence of greater predetermined number of by-passed calls causes a similar transfer of a second car. These two cars then reverse their upward travel at progressively lower remembered by-passed landing calls until all such calls have been answered. The third car continues to respond to upper floor demand on its original basis, but its bypass call detection circuit is inoperative during transferred operation of either of the other cars. A car by-passes up landing calls during its ascent when it is subject to transfer assignment. Specifications 894,755 is referred to.

The surface quality gauge may be used in conjunction with a size gauge, the quality gauge being aptomatically brought into action when a predetermined size is reached, and the control being completed when both the size and quality have reached predetermined values. The surface quality, gauging may be effected after machining, with retroactive control of the machine.

Title: Manufacture of organic amine salts of penicillins
IPC: C07D499/24
Filed: 1948-06-30
Abstract: Diethylaminoethyl p-aminobenzoate salts of penicillins (especially of penicillin G) are manufactured by adding diethylaminoethyl p-aminobenzoate to a solution of penicillin in p  an organic solvent in which the salt to be formed is soluble (e.g. tetrachloroethane, methylene dichloride or especially chloroform), concentrating the resulting solution if necessary, and then adding another organic liquid miscible with the first but in which the salt obtained is relatively insoluble (e.g. methyl ethyl ketone, benzene, diethyl ether, diethyl carbonate, carbon tetrachloride or especially ethyl acetate), whereby the salt is obtained as a crystalline solid which is separated from the liquid, e.g. by filtration or decantation. When concentration is effected by evaporation, there is advantageously added to the mixture, before evaporation is complete, a "carrier liquid" consisting of an organic liquid which is of higher boiling point than the solvent being or to be evaporated and in which the penicillin salt is not very soluble (e.g. benzyl alcohol, nitrobenzene, amyl acetate, n-butanol, amyl alcohols, b -ethoxyethanol, xylene, cyclohexanone or especially cyclohexanol). Examples illustrate the use of certain of the organic liquids enumerated above.  Specification 661,272 is referred to.

Title: A method of reviving silicate sealing solutions
IPC: C04B41/85
Filed: 1965-04-28
Abstract: A method of sealing an aluminium oxide coating with an aqueous alkali silicate solution and maintaining the operability of said solution comprises treating aluminium formed with an oxide coating at an elevated temperature, e.g. 205 DEG F, in the alkali silicate bath and, when turbidity appears in the bath, adding a sufficient quantity of alkali to cause the disappearance of said turbidity when the solution is heated or left-standing, heating the solution or leaving it to stand to effect disappearance of said turbitidy and then adjusting the pH of the solution back to the operating value.  The solution may for instance comprise a 5% solution containing Na2O and Sio2 in a ratio of 1:3.2 and have a pH of 11.0.  The amount of alkali required to revive the solution is that which will increase the pH to about 12, in most instances.  During the reaction which removes the turbidity from the solution the pH will drop back to about 11.  Any adjustment of the pH then necessary may be achieved by addition of further alkali or by addition of a weak acid, i.e. boric, tartaric or acetic acid.
