Title: Improvements in or relating to control circuit arrangements
Inventor: DHEN WALTER
IPC: H03K19/003
Filed: 1962-02-12
Abstract: 953,027. Electric selective signalling systems. LICENTIA PATENT-VERWALTUNGSG.m.b.H. Feb. 12,1962,No. 5288/62. Heading G4H. In a control circuit, for example in which it is necessary that certain switching operations should be carried out only after certain other switching operations have been performed, logic circuits are used to determine whether or not an operation can be performed. The logic circuits comprise AND and OR gates as illustrated. Circuit 1 is similar to circuit 2, all AND gates being replaced by OR gates and vice versa. Each gate A1, A2, ... corresponds to a certain combination of conditions upon which the permissibility of operating switch unit 13 depends. The signals fed to circuits 1 and 2 are the inverse of each other, i.e. are X and X. In use if, for example, signals x 11 , x 12 , ... arrive at AND gate A1, gate 010 will give an output F1. If the system is operating correctly, signals #X 11 , #X 12 , ... arrive at OR gate 01, which gives no output. Gate A 10  gives no output F2 and output F2. The system is operating correctly if F1 = #F2. Signals F2 and F1 are therefore fed to logic circuit 15, which gives an output R if F1 = F2. Outputs R, F1 and F2 feed AND gate 11, and if a further actuating switch 10 is depressed a further signal K is fed to gate 11, whereupon it gives an output permitting actuation of unit 13. An alarm 9 is operated if there is no output R from circuit 15.

Patent GB-1081090-A (GB)
Title: Parenterally administrable, sustained release pharmaceutical compositions
IPC: A61K9/22
Filed: 1965-02-11
Abstract: Injectable sustained release compositions comprise an emulsion or dispersion of a pharmaceutically active ingredient dispersed in a mixture of a non-toxic film-forming material capable of gelation in the body at the injection site to form a permeable membrane enveloping the active ingredient, with a thixotropic agent, and an ion-exchange material.  The active ingredient may be in finely divided solid form or dissolved or dispersed in a carrier liquid, which is preferably aqueous.  The film-forming material is a vegetable oil such as castor, safflower, linseed or oiticica oil, preferably together with a proteinaceous material such as oxidised or refined gelatin, white of egg or casein, or hydrolytic or enzymatic degradation products of proteins.  Gelation is produced on injection by the effects of in vivo conditions, such as oxidation, temperature, chemical action, or usually by pH change; alternatively a second injection of, for example, dilute acetic acid, may be employed to cause gelation.  The thixotropic agent, which is for fluidising the composition during injection, may be finely divided silica, carboxymethyl cellulose, agar or bentonite.  Ion exchange materials, which provide for slow permeation of the drug through the membrane, are suitably sulphonated styrene/divinyl benzene resins in cation form.  Active ingredients may be antibiotics such as the following tetracyclines: chlor-, oxy-, brom-, 6-demethylchlor-, 6-demethyl-6-deoxy-, and 6-demethyl-6-deoxy-7-brom-tetracycline, or tetracycline itself; and also their magnesium chloride complexes; enzymes such as papain, hormones such as hydrocortisone, or prednisolone; anthelmintics; and tranquilisers such as reserpine and meclizine, salts, e.g. sodium chloride, or injectable iron compounds. Aqueous propylene glycol may be used as a liquid carrier.
