Title: Line scanning circuit for TV tube - uses transistor with capacitance feedback and cut=off by line pulse fed via series diode
Inventor: LINS JUERGEN DIPL ING
IPC: H03K4/62
Filed: 1979-09-24
Abstract: A line scanning circuit for a TV tube has the scanning coil (L2) connected from the collector of a transistor (TS) to a shift potentiometer (R5), decoupled to earth by a capacitor (C3). The transistor is fed from the positive supply (UB) via a choke (L1) and variable resistor (R4) which sets the scan width. An RC feedback circuit (R2lR1,C2) is connected from collector to base, which has a bias resistor (R3) to the positive supply. The negative line synchronising pulse (E) drives the base via a capacitor (C1) and series diode (D2), and is clamped to earth potential by a shunt diode (D1). The series diode (D2) only conducts during the pulse, when it cuts the transistor off. The feedback circuit impedance is high compared with the pulse source impedance. After the pulse, the collector voltage falls linearly due to the feedback. At the next pulse, the collector voltage rises rapidly as the stored energy in the coil (L2) and capacitor (C3) makes a half-cycle oscillation. The advantages of the circuit are low current consumption few components and good linearity.

Title: Measuring and transmitting apparatus used in drill string - is self-contained and forms output signals modulated into mud flow
Inventor: CLAYCOMB JACKSON REYNOLDS
IPC: E21B47/18
Filed: 1979-10-08
Abstract: Appts. for use in a drill string forms a signal of downhole drilling information. It has a tubular elongate outer body which is connectable both ends in a drill string. An inner body is enclosed in the outer body and is positioned to form a mud flow annular space between the two bodies. A motor converts mud flow through the annular space into rotational torque. The water drives a shaft which is connected to a hydraulic pump for pumping hydraulic fluid to an elevated pressure. A constricted passage in the annular space is located so that mud flow through the space is directed through the constricted passage. A plug is movably activated by a piston to vary the constriction on the mud flow with movement of the plug. A hydraulic circuit connected to the pump uses hydraulic fluid in conduits through a controllable valve to the piston and cylinder for moving the plug to an altered position to modulate the mud flow and thus form an output signal dependent on the manipulation of the controllable valve. The invention provides a self-contained device which forms the output signals modulated into the mud flow. The device is self-contained in that it generates its own electrical power for operating transducers, and the signal are imposed on a two-position, four-way valve.

Title: Electric contact mfr. - where contacts are coated with flux and then dipped in molten eutectic tin-lead bath so working surface of contact is coated with solder
Inventor: BAHNSEN HEINER
IPC: H01H11/04
Filed: 1980-03-21
Abstract: An untreated contact is first activated by exposure to aggressive fluxes, and is briefly dried. The contact is then immersed in a bath of solder consisting of a tin-lead eutectic at 240 deg.C. The immersion time depends on the thickness of the solder coating required on the contact, which is next drawn vertically upwards out of the bath and washed with warm water. With all types of electric plugs and sockets demanding high performance, costly metals such as Au-Ag-Pd are normally employed, and are applied to the contacts by electroplating. The invention provides efficient, stable, and inexpensive contacts which do not possess the disadvantages entailed with plated contacts, viz. porosity, roughness, and variation in thickness.
