Title: Improvements in or relating to stiffening caps for boots and shoes
IPC: A43B23/08
Filed: 1927-05-17
Abstract: 276,929. Filko Chemische Fabrik Ges. Oct. 14, 1926, [Convention date]. Stiffeners.-A stiffening cap for boots or shoes made by employing resin and paraffin as an impregnant, is characterized by the addition of talc. The process consists in melting 57.7 kilogrammes of resin and heating it to 220‹ C., then 35 kilogrammes of talc are gradually added. 7.5 kilogrammes of paraffin with a melting point of 55‹ C. are next added. Lower melting paraffin may be used but in diminished quantities. The molten mass, stirred from time to time, is drawn off into a pan through which the materials to be impregnated are passed mechanically. The saturated materials are then passed through rollers and cut up into metre lengths. Heel and toe caps are stamped out of the material and bevelled. The stamped caps are electrically heated and are ready for insertion in shoes. Instead of resin, pitch may be partly employed and the talc is partly replaceable by gypsum or other finely grained materials.

Title: Transistor amplifier with automatic gain control
IPC: H03G3/00
Filed: 1960-04-14
Abstract: 873,537. Transistor amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 14, 1960 [April 17, 1959], No. 13396/60. Class 40(6) In order to prevent distortion of strong signals applied to a transistor amplifier having automatic gain control further manual gain control is effected by connecting the impedance through which the automatic gain control current flows to a point of adjustable potential. The transformer winding L across which the I.F. input signal is applied, is connected through an impedance comprising resistors R 1 R 2  to a source of negative potential. The junction of resistors R 1 R 2  is connected to ground through variable resistor R 3  which functions as a volume control, and the A.G.C. current is fed to the junction of coil L and resistor R 1 . When the movable contact of R 3  is moved to the left the current through resistors R 3 , R 2  increases and the base voltage of transistor T becomes more positive, thus providing a further decrease in the gain.

Title: Electrical monostable circuit for amplifying read-out signals
IPC: H03K3/284
Filed: 1963-04-05
Abstract: 961,008. Transistor monostable state circuits. STANDARD TELEPHONES & CABLES Ltd. April 5, 1963 [April 6, 1962], No. 13694/63. Heading H3T. A monostable state circuit comprising two active elements in which in the stable state one element is conductive and one is non-conductive, and in the other state the conductivity of both elements increases. As described, a pulse lengthening circuit for a magnetic core matrix comprises a reciprocally coupled pair of opposite conductivity transistors trl, tr2. In the normal state transistor trl is conducting in the class A region, and transistor tr2 is cut off. Application of a negative pulse on the base of transistor trl causes transistor tr2 to switch to its saturated condition, the feedback via the common emitter coupling also saturating tr1 After a time determined by capacitor Cd1 and its associated resistors, transistor tr2 again cuts off and transistor trl reverts to its class A state. Switching on of the transistor tr2 may be inhibited by the application of a negative pulse at terminal bn5. The input circuit includes a pair of diodes di1 di2 which ensure that the input signal at the base of transistor tr1 is always negative. With very small level signals, neither of the diodes di1, di2 are cut off, thus presenting a very low impedance across the primary of transformer tf, and preventing spurious operation of the circuit.

The reaction is preferably carried out at temperatures below about 100 DEG  C., advantageously in solution or suspension in an inert organic liquid, e.g. chloroform, 1 : 1 : 2 : 2-tetrachlorethane or preferably a volatile water-miscible organic solvent, such as methanol, ethanol, isopropanol, dioxane or glycol mono-ethyl or -methyl ether, in the presence or absence of water.  In examples: (1) l-cysteine hydrochloride is heated with ethyl G-penaldate in aqueous alcohol in the presence of sodium acetate to produce des-dimethyl monoethyl G-penicilloate (R=benzyl, R1= ethyl, R1111=H); alternatively, cysteine free base is employed and the sodium acetate is omitted; (2) cysteine hydrochloride and ethyl nor-G-penaldate are allowed to stand at room temperature in alcohol in the presence of potassium acetate, yielding ethyl des-dimethyl-nor-penicilloate (R=phenyl).  Esters of cysteine similarly yield products in which both the carboxyl groups are esterified.  Sulphates, phosphates or hydrobromides may be used instead of hydrochlorides.  Alkali metal salts may be prepared from the free acid products or obtained directly by using the alkali metal salts of cysteine.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of compounds of the first general formula given above in which R11 and R111 represent alkyl radicals, and contains additional examples in which the aminoacid starting material is penicillamine hydrochloride (R11=R111= methyl).
