Patent GB-458642-A (GB)
Title: A process for the production of films, strips, filaments or other objects
IPC: C08L1/08
Filed: 1936-03-25
Abstract: Films, strips, filaments, or other objects are formed from a composition comprising a cellulose ester and/or ether and a relatively small amount of a solid insoluble metallic phthalate dispersed therein.  In a modification, a phthalated pigment may be used instead of the metallic phthalate, i.e. a pigment on the surface of which a phthalate has been formed or phthalic acid has been adsorbed by immersion of the pigment in a solution of phthalic acid. Suitable phthalates are those of titanium, lead, copper, cobalt, cadmium, manganese, iron, barium and mercury. These pigments transmit very little ultra-violet light.  When making artificial silk sufficient pigment may be added to produce a delustred appearance, i.e. 5--15 per cent of the weight of cellulose.  For films a smaller amount is used, e.g. 1--5 per cent, transparency being thereby retained and ultra-violet light transmission reduced.  Such films are very suitable for packing foodstuffs or for safety glass.  The pigment is preferably dispersed by pebble mill grinding.  A phthalated pigment may be prepared by standing 1000 grams of antimony oxide, barium-titanium oxide pigment or of calcium-titanium pigment (a mixture of titanium oxide with a small amount of a calcium compound) in a 0,7 per cent solution of phthalic acid overnight. These pigments adsorb phthalic acid.  Leaded zinc (5--50 per cent lead sulphate and 95--50 per cent zinc oxide) on the other hand immersed in a 1--5 per cent solution of phthalic acid reacts therewith to produce a zinc phthalate-containing complex.

Filed: 1962-03-12
Abstract: 968,126. Battery charging systems. C. M. SAYER, and E. N. BRAY Ltd. March 26, 1963 [March 12, 1962; Oct. 23, 1962], Nos. 9445/62 and 40027/62. Heading H2H. A battery used as an emergency supply is put on charge each time that the battery supplies a load for a given period. On failure of the supply a mains failure relay opens contacts MC1 and closes contacts MC2 which energizes a shunt wound timing motor TM, which if all or a determined fraction of the mains failure period exceeds 10 minutes, moves cam-operated switch TM1 to the upper position and closes cam switch TM2. On restoration of the supply, the battery is charged and contacts MC1, MC2 are changed to the positions shown. When the battery voltage rises to a determined level a voltage relay VR closes contacts VR and CR through CR which re-energizes the motor which runs for about four hours before changing over contacts TM1, TM2 to the positions shown. If subsequently the battery voltage drops due to standing losses, relay CR2 operated through relay VR2 will be closed and will operate the circuit through the above cycle to charge the battery. In an alternative arrangement, the timing motor TM is a synchronous type driven through a transistor oscillator.

In a demodulator for an amplitude modulated signal comprising a non-linear resistor the slope of the current/voltage characteristic of which is the same for a given magnitude of voltage whatever its sign; the signal is connected to the load through the non-linear resistor to which is also applied a demodulator voltage source having a frequency equal to half that of the signal carrier. The non-linear resistor may comprise a pair of oppositely poled rectifiers in parallel, and backbiasing arrangements as described with reference to Fig. 3 (not shown) may be included. Reference source 6, Fig. 1, having a voltage large compared with the signal from source 1 is applied to a transformer 5 the secondary 4 of which has a centre tap connected to a load 7, and the signal v sin (2 pt + a) in passing through the non-linear resistors which have a conductance varying predominantly at twice the frequency of source 6, results in a direct current through load 7 which is dependent on the modulation of the signal and the phase of the carrier. Even harmonics of voltage 6 are removed by filtering and if resistor 3 and the corresponding half of secondary 4 are omitted it would be necessary to remove or compensate for a large component of source 6. An arrangement in which two reference sources equal in amplitude and in phase quadrature are employed to cancel harmonics in the output is described with reference to Fig. 2 (not shown) and further embodiments in which the rectifier bias is produced by a resistor-capacitor network are described with reference to Figs. 5 and 6 (not shown).
