Title: Electrical impulse counting circuits
IPC: H03K23/82
Filed: 1953-02-05
Abstract: 724,672. Multi-stable state circuits. NATIONAL CASH REGISTER CO. Feb. 5, 1953 [Feb. 20, 1952], No. 3234/53. Class 40 (6). [Also in Group XIX] In a multi-stable state circuit which includes a series of gaseous electronic discharge devices connected to be rendered conducting in turn in response to pulses applied to all the devices, the establishment of conduction in a device causing any previously conducting device to be extinguished, the devices are arranged alternately in the series and are connected in two operational groups, the operational circuit for each group including an individual impedance from which, when a device in the group is rendered conducting, a pulse is derived to cause extinction of any previously conducting device in the other group. In a first embodiment a series of cold-cathode tubes 0 ... 9, Fig. 1, are linked by direct connection of the probe electrode P of each tube to the igniter I<SP>2</SP> of the next higher tube. The cathodes of the even-numbered tubes are connected in one group with a common impedance 31 leading to earth, and the oddnumbered tubes are similarly connected through an impedance 35; the two groups are coupled by a capacitor 40 and a common impedance 33. Assuming the " 0 " tube to be conducting, the positive potential acquired by its probe P is applied to the starting gap of the " 1 " tube, and when a negative impulse appears across a common input impedance 39 the combined effect causes tube 1 to fire. The consequent rise in potential at its cathode is transmitted as a positive pulse through the coupling capacitor 40 and extinguishes the tube " 0." The arrival of subsequent input pulses causes further stepping of the discharge along the series of tubes in a similar manner. Each time the discharge passes from " 9 " to " 0 " a " carry " pulse to the next denomination is passed on via a tube 24. In a second embodiment the discharge is stepped along by positive pulses applied to the anodes of the tubes and instead of the coupling capacitor 40 and common load 33, capacitors are connected across separate cathode loads for each group. The " carry " pulses in this embodiment are passed on via a thyratron. In a third embodiment, Fig. 3, all the cathodes of the counter tubes are earthed and the anodes are connected in two groups. Also connected in separate groups and serving for the application of the input impulses, are igniters 1<SP>1</SP> not used in the other embodiments. Instead of separate tubes the electrode systems could all be included in one envelope.

Abstract: 908,165. Voltage measurement. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Jan. 31, 1961, No. 3669/61. Class 37. A potentiometer circuit for measuring small D.C. voltages employs a source of D.C. power controlled by a Zener diode so as to give a constant potential regardless of current in the circuit. Fig. 2 shows such a circuit wherein a battery 2 and a series resistor 6 is shunted by a Zener diode 7 and by a resistor R. The resulting output is applied across the fixed resistance elements I and II of a potentiometer having decimal tapping elements III and IV across which a small D.C. voltage to be measured is applied via a galvanometer 5. When the decimal elements III and IV have been adjusted to obtain a null reading of the galvanometer the value of the unknown D.C. is obtained by simple ratio from the potentiometer readings. A method of measuring small resistances is described in which a known resistance RK, Fig. 6, is connected in series with an unknown resistance RX and balance, indicated on galvanometer 5, obtained with a potentiometer circuit 1 by means of a voltage adjuster 13, the said potentiometer including a Zener diode controlled voltage source. After balance has been obtained a switch 14 is moved to couple the unknown resistance RX via the galvanometer to the adjustable tapping elements III and IV of the potentiometer and balance again obtained by adjusting the elements III and IV. The value of RX is again found by simple ratio from the potentiometer readings.

Title: Improvements in compounded plastics
IPC: C08L81/00
Filed: 1936-02-06
Abstract: A composite material comprises a heat treated mixture of graphite and an olefine polysulphide plastic, with or without amorphous carbon and/or other fillers.  In preparing the material, the plastic is masticated with softening and activating agents such as dibenzothiazyl disulphide, tetramethylthiuram disulphide, diphenylguanidine and zinc oxide, and with fillers such as carbon black, kaolin, blanc fixe, and fibrous material, e.g. leather scrap and asbestos powder, graphite is incorporated, and the product is heated under pressure in one or more stages to polymerize the plastic.  Partial polymerization may be effected by rolling or pressing the material into sheets or by extruding with heat, and the final polymerization by dry heat or steam heat or by the "wrapped cure" as in the vulcanization and curing of rubber. In the production of thin articles such as washers, the compounded material may be rolled into sheets, polymerized between heated platens, and the articles then punched from the sheet.  In the manufacture of more massive articles, e.g. bearings, the compounded material, in the form of a pile of sheets or in blocks, may be partly polymerized, the agglomerated mass coarsely ground, and the powder then moulded under heat and pressure.  In examples, the material is prepared from mixes containing an olefine polysulphide plastic, graphite, carbon black, zinc oxide, diphenyl guanidine, dibenzothiazyl disulphide, and stearic acid with or without blanc fixe.  Specifications 302,270, [Class 2 (iii)], 354,310, 354,394, and 360,890 are referred to.

Abstract: 1449924 Pack diffusion of chromium and vanadium INSTITUT FUR HARTEREITECHNIK 25 Jan 1974 [26 Jan 1973] 03701/74 Heading C7F The production of hard wear and corrosion resistant skins on the surface of ferrous materials is carried out by the simultaneous diffusion of chromium and vanadium by heating, for preferably 2-4 hours, in the presence of chromium and ferro vanadium optionally together with an actuator and a filler. The activator may be ammonium chloride, with an inert filler such as alumina. With ferrous materials of 0À6%C or more, a typical powder composition would be 50% Fe-V, 30% Cr 10% activator 10% filler. With base materials of 0À25-0À6%C, the ferro vanadium content would be 40% the chromium 40%. Treatment temperature is between 950-1200‹C, preferably 1100‹C for steel materials, 1050‹C for cast irons, resulting in 20-50Ám thick skins dependent on length of treatment. Where initial materials have less than 0À2%C, a preliminary carburization treatment is required to increase the content to 0À6% or more. Alternatively, simultaneous diffusion can be carried out in a vacuum of 10<SP>-3</SP> torr, although in this process, no actuator is required.
