Patent GB-830914-A (GB)
Title: Protecting elastomers against atmospheric degradation
IPC: C08K5/00
Filed: 1957-05-17
Abstract: An olefinic elastomer is protected against the action of atmospheric agents by incorporating therein, at the end of the mixing cycle, between 0.1 and 5% by weight of the elastomer of a nickel xanthate of the formula <FORM:0830914/IV (a)/1> wherein R and R1 are each an aliphatic, olefinic, aromatic or alicyclic hydrocarbon radical of not more than 12 C atoms. Elastomers specified are natural rubber, copolymers of butadiene with styrene or acrylonitrile, polychloroprenes and polyisoprenes. The slight coloration imparted by the xanthates may be masked by titania.  It is stated that certain antioxidants, e.g. the phenylene-diamines, or activators, e.g. zinc mercapto-benzimide azolate, have a synergistic effect on the xanthates, and that certain fillers having a high absorbent power, e.g. C blacks, result in a further improvement in the resistance to atmospheric action.  The xanthates may also act as secondary vulcanization accelerators.  In examples, Ni isopropyl xanthate is incorporated in conventional solid or latex rubber mixes.

The cyclopropa[c]quinolines are prepared in appropriate cases by reacting a compound of formula <FORM:1015624/C2/2> in which Y, R4 and R5 are as defined above; R1 is hydrogen, halogen, trifluoromethyl, lower alkyl, lower alkoxy, nitro, mono-lower alkyl-amino, di-lower alkylamino, lower alkanoyl-amino, lower alkoxy-carbonyl, carbanoyl or sulphanoyl; R2 is hydrogen, halogen, lower alkoxy, or together with R1, methylenedioxy; and R3 is lower alkyl, di-lower alkylamino-lower alkyl, benzyloxy, lower alkoxy, or benzyl, with trimethyl sulphoxonium iodide, in the presence of a strong base. Compounds in which R1 is an amino group are prepared by reduction of the corresponding nitro compound, where R1 is carboxy by hydrolysing the corresponding alkoxy-carbonyl compounds, and where R1 and/or R2 are hydroxy, and/or R3 is hydroxy, by cleavage of the corresponding methoxy and benzyloxy compounds. The N-unsubstituted compounds are prepared by hydrogenation of the N-benzyl or N-hydroxy derivatives. Nitro-substituted compounds in which R3 represents hydrogen are prepared by oxidizing the corresponding amino compounds. Compounds in which Y represents sulphur may also be prepared by treating the oxo compound with phosphorus pentasulphide.  The carbostyril starting materials may be prepared by oxidizing a quaternary salt of quinoline to give the N-alkyl carbostyril. The thio-carbostyrils are prepared by treating the corresponding carbostyril with phosphorus pentasulphide. The N-benzyloxy and -lower-alkoxy-carbostyrils are prepared by oxidizing a quinoline-1-oxide, treating the N-hydroxy compound with sodium or potassium hydroxide, and reacting the resultant salt with an excess of benzyl halide or an alkylating agent.  Therapeutic compositions useful as sedatives and muscle relaxants contain as active ingredients compounds of the first formula above.

Title: Electronic circuital element
Inventor: COUPLAND MICHAEL JOHN
IPC: H01L31/16
Filed: 1963-04-25
Abstract: A semi-conductor device consists of a body 1 of A3B5 material with a resistivity greater than 105 ohm-cm. to opposite faces of which are attached a radiation emitting PN junction diode 2, also of A3B5 material, and a radiation sensitive layer 7 which may but need not contain a PN junction.  The body 1 is transparent <PICT:1080732/C4-C5/1> to the radiation emitted by the diode 2 and the device operates as a switch or relay, radiation emission being initiated by energizing input terminals 4 and 5 and detected as a resistance change or voltage between the output terminals 8 and 9. Preferred materials are: for the body portion 1, gallium arsenide or phosphide or arseno-phosphide; for the emitting diode 2, gallium arsenide either alone or in combination with indium arsenide or gallium phosphide; and for the layer 7, germanium or germanium-silicon or gallium arsenide.  In use, radiation (e.g. 9000 <\>rA infra-red radiation) emitted from the diode 2 either effectively short circuits the output terminals when, as in the case illustrated, the output layer 7 is photo-resistive or provides an output e.m.f. if the latter layer contains a PN junction. There may be a plurality of separate PN junctions in the input layer 2, providing a plurality of pairs of input electrodes.  Such an arrangement can function as an "OR" gate, and the input can have one common electrode (Fig. 3, not shown), or be totally isolated from each other (as in Fig. 4, not shown).  A transistor may be associated in the device either as a simple amplifier or to convert an " OR " gate embodiment into a " NOR " gate.  Such transistors may be formed in the same semi-conductor body as the device itself.  Reference has been directed by the Comptroller to Specification 967,439.

Patent GB-760752-A (GB)
Title: Electrical digital computing engines
Inventor: PETHERICK EDWARD JOHN
IPC: G06F7/52
Filed: 1954-06-03
Abstract: 760,752. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 24, 1955 [June 3, 1954], No. 16498/54. Class 106 (1). An electrical calculating-machine comprises a translator for deriving a series of multiplier factors from a succession of multiplier digits, the derivation being based on the principle that in decimal arithmetic direct multiplication by a factor greater than five is not necessary, for example multiplication by 7 can be effected by multiplying in turn by 10 and - 3 and summing the products. The device described is similar to the " multiplier factor selector " described in Specification 745,879 which is referred to, but differs in that decimal digits are fed to it successively in order of increasing significance, and because of this it is possible to effect the determination of the multiplier factor using a register having only one stage. This stage is shown in Fig. 2 as consisting of a multi-cathode tube 1 having an anode A between which one or more discharges can be set up simultaneously. The decimal digits come from a drum S in a two-out-of-six code, as described in Specification 745,879, the six leads 0/9, 1/8, 2/7, 3/6, 4/5 and 7/4 being connected respectively to the cathode C0, C1, C2, C3, C4 and C7, and depending upon which cathodes have discharges on them, one or more of the gates 10-16 will be open. Consider for example the determination of the multiplier factors for a multiplier of 27. Before the least significant digit is set up, triggers 4 and 19 are reset off. The 7 is then set up, cathodes C2 and C7 having discharges on them, and because of a beginning element 5, trigger 4 is put on. Then a control pulse applied to a gate 2 causes the discharges in the tube to be stepped clockwise one stage, trigger 4 being on, and when the discharge leaves cathode C7 trigger 4 is put off by an end element 6. Trigger 19 is then put on by a further control pulse and lines X3 and " subtract " are energized, indicating a multiplier factor of - 3. Next, in succession, trigger 4 is reset off by a pulse from a delay 9; the tube 1 is cleared, end element 6 putting trigger 4 on; the next digit 2 is set up, cathode C2 having a discharge on it, the contents of the tube are shifted, and trigger 19 is put on energizing lead X3 indicating a multiplier factor of 3. Finally, the tube is cleared, zero is set up, and as trigger 4 is not on the discharge is not shifted, and lead X0 is energized. The three multiplier factors are thus - 3, + 3 and 0. It is stated that with the addition of suitable gates the anode-tocathode paths in the tube could each be replaced by a single two-state device, and a modification using one stage of the stage register of Specification 745,879 is outlined. Specification 717,114 also is referred to.
