Title: Automobile electrical contacts for use in distributors and contact breakers for internal combustion engines
IPC: F02P7/02
Filed: 1965-08-15
Abstract: An automobile electric contact for use in distributers and contact breakers for internal combustion engines includes a sintered body formed from tungsten carbide mixed with from 6 to 35% by weight of powdered elemental cobalt. The contact may also contain iron, nickel, titanium carbide, tantalum carbide, chromium carbide, molybdenum carbide, tin or chromium specified percentages.  The contact may be plated with nickel where it is to be soldered to a support block.  A method for making the contact comprises the steps of mixing the powdered cobalt with powdered tungsten carbide; reducing the powder mixture, mixing a binder with the powder mixture to form it into granules, compressing the granules to mould into a moulded body, and firing to sinter the moulded body in a reducing atmosphere.

Title: Improvements in and relating to devices for the modulation of wireless transmitting apparatus
IPC: H03C1/62
Filed: 1930-11-14
Abstract: 363,480. Wireless transmitting systems. BARON, H., 231, Strand, London.-(Lorenz Akt..Ges., C. ; 1, Lorenzweg, Tempelhof, Berlin.) Nov. 14, 1930, No. 34356. [Class 40 (v).] In a radio transmitter, the modulating system is arranged to vary the mean value of the aerial current in accordance with the prevailing signal strength in such a way that the lower limit of aerial current is maintained substantially constant. As shown in Fig. 2, modulation is effected by the signal currents amplified at V and applied to a winding W1 on the iron-cored choke D in the aerial circuit. The signal currents are also applied via a transformer T1 to a rectifier R3, and the rectified voltage is applied to a valve R1 causing the direct current through a resistance n in its plate circuit to vary in accordance with signal volume. These variations are amplified in the valve R2 and applied to a second winding W2 on the choke D. In a modification, Fig. 4 (not shown), only a single control coil W2 in the plate circuit of the valve R2 is used, but the grid circuit of this valve receives the signal voltages from the amplifier V as well as the volume voltages from the resistance n. A full-wave rectifier may replace the rectifier R3 and valve R1, Fig. 6 (not shown). When thermionic modulation is employed, Fig. 8, the grid circuit of the modulating valve R4 receives its high-frequency input through a coupling L1, its signal input through a transformer T2 from the amplifier V, and its signal volume input through a resistance n traversed by the rectified signal voltage.

As shown, a member 14 is pivoted at 16 to a main body 12 of the former and has an operative part, to the left of Fig. 1, which is biased away from the main body by a spring 20, the part to the right of the pivot 16 carrying a stop 22. A source of suction, supplied through a pipe 41 to passageways 48, 50, 52, 53 leading to outlet ports 54- 61 in the front face of the former, holds the material on to the former while it is being wrapped and glued. After the wrapping operation compressed air is introduced through a pipe 28 into a cylinder 24 to force a piston 26 downwardly against the member 14 and pivot the latter toward the main body 12 of the former, the source of compressed air being controlled by a valve 34 operated by a cam 36 and follower 38. When the former 12, 14 has completely collapsed and the piston 26 has reached the end of its travel a port 62 is uncovered so that compressed air passes into a passageway 64 leading to five orifices 68, 70; 76 in the end face of the body air jets issuing from the five orifices blowing the packet off the former. The jets may be inclined to the axis of the packet so as to miss the package when the latter is ejected into a holder 92.
