Title: Signal attenuator system with FET in signal path - has DC feedback circuit counteracting impedance changes of FET
Inventor: STEVENS DAVID WILLIAM
IPC: H03H11/24
Filed: 1976-11-04
Abstract: The attenuator has devices (11, 12) which can derive a DC signal representative of the impedance offered by the FET (1) to an applied signal. There is a DC feed-back circuit (13, 15) which controls the FET (1) so that any changes in its impedance are counteracted. The FET (1) is connected to a resistor (2) and an inductance (3) in series. A further resistor (4) is connected in series with the inductance (3). An input signal (6) passes through a capacitor (7) to the point between the first resistor (2) and the inductance (3).

Title: Heel plate for cross-country ski - has short upwardly projecting studs preventing ski boot heel slipping off plate
Inventor: DASSLER ADOLF
IPC: A63C9/084
Filed: 1976-12-30
Abstract: Since for cross country skiing, the heel of the ski boot (4) must be free to move away from the mounting base plate (6), only the toe section of the boot is anchored by the binding. When the skis are sideways inclined, the ski boots heels sometimes slip off the ski due to lack of support. This condition is improved by providing the heel plate (6) on the ski with a number of short upright studs (7). Thus when the heel of the ski boot comes down on the heel plate, the studs (7) on it dig into the soft layer (5) on the ski boot heel. In this way, lateral slipping of the ski boot heel can be prevented.

Patent DE-2728417-A1 (DE)
Inventor: NATENS MARCEL CLEMENT RENE
IPC: H03M1/00
Filed: 1977-06-24
Abstract: This signal converter can operate both as a digital/analog converter and as an analog/digital converter and exhibits a charge generation device with a single set of weighted capacitances (C8-C13) and a charge storage device, coupled to these, with second capacitances (C1, C2). The charge generation device is designed for generating various charges with the aid of which the charge in the charge storage device can be changed step by step. In digital/analog conversion, a charge related to a digital value is built up in the charge storage device. In analog/digital conversion, a charge initially stored in the charge storage device, which corresponds to an analog input value, is changed step by step towards a predetermined reference value, for example zero. <IMAGE>

Title: Pot-shell for electrolytic aluminium reduction cell - with stiffeners disposed against walls which act as cooling ribs
Inventor: SANDVIK EYSTEIN
IPC: C25C3/08
Filed: 1977-08-05
Abstract: A potshell for an electrolytic cell comprises a bottom plate, side walls and end walls formed of steel plates. Vertical stiffenesss are disposed against the exterior of the side walls and a reinforcing frame surround the stiffness. Vertical, free air passages are provided between the stiffness and walls and the stiffeners act as cooling ribs for conducting and dissipating heat from the walls. Used for electrolytic reduction of aluminium placing of the resinforcing frame clear of the potshell sides results in only small thermal stresses and maintenance of low temps. The air currents are guided in towards the sides of the potshell. The vertical stiffeners offer little air resistance and prevent accumulations of alumina building up along the sides of the potshell.

Title: Thermal expansion measurement system error correction - compares lengths of material with different thermal expansion coefficients
Inventor: HAFERKORN WOLFGANG ING GRAD
IPC: G01B5/00
Filed: 1978-07-14
Abstract: The method is for connecting adjustment errors caused by temp. dependent length variations in systems for measuring distances on electronically controlled machines etc. and is partic. applicable to machine tools. It enables the distance between the working plane and the measurement plane to be effectively reduced to zero, thus eliminating that error source.
