Title: Battery charge monitor and switching circuit - comprises potential divider network having two diodes in series with zener diode
IPC: H02H7/18
Filed: 1975-02-22
Abstract: The battery voltage monitor comprises a potential divider network of two diodes (D1, D2) in series with a zener diode (Dz) connected across the battery terminals. If the battery voltage exceeds a value set by the forward voltage sum of the three diodes, a PNP transistor (T1) conducts, switching on an NPN transistor (T2) which energises a relay (d1). The relay contact (d1) closes and connects the load to the battery, bypassing the diodes via third diode (D3). A falling battery voltage reaching a value set by the forward voltage sum of the third diode (D3) and the zener diode, causes the relay to become de-energised and disconnects the load. Manual switching-on is possibla by means of a push-button switch (b1) which temporarily shorts out the two series diodes (D1, D2).

A hand operated balance is applied from above at the ski middle for its bending resistance measurement. The contact pickups are built in sliding supports resting on a supporting bar, on which they can be placed and fixed to fit the tested ski length. A signal lamp in the display unit is allocated to each contact pickup. They light up by a contact closing, when the torsional angle exceeds about 12 deg.

Title: Frequency converter for colour TV signals - has LC sink varied to allow independent audio and video carrier level adjustment
Inventor: SOMMER KURT
IPC: H04N7/10
Filed: 1975-04-02
Abstract: The frequency converter, for colour television signals in large common antenna systems, allows the audio and video carrier levels to be adjusted and held constant independently without affecting signal quality. The received signals are converted into IF. The IF is then converted into output signals suitable for transmission over the common antenna system's cables. Separate audio carrier level control is achieved by altering an LC sink (12) acting as audio carrier bandstop in the AF region. The signal used to control the LC sink is derived from the bandstop's output. A PIN diode is included as control element.
Patent DE-2515684-A1 (DE)
Inventor: COHEN SAM G
IPC: G04G9/06
Filed: 1975-04-10
Abstract: A horological instrument includes a liquid crystal electro-optical display which simulates the movement of hands about a center by activating circumferentially spaced radial conductive segments. Generally, for the liquid crystal material between two corresponding segments to be activated an electrical potential must be applied between the segments which is, typically to achieve full brightness, substantially greater than the activation voltage of the liquid crystal material. The present invention effects activation of a selected segment-hand by applying an electrical potential, predetermined greater than the activation voltage, between the selected segment-hand and a corresponding segment or electrode. However, the deleterious effects of leakage currents and/or unwanted activation of a segment-hand not selected for activation is reduced by applying an electrical potential between all unselected segment-hands and their corresponding segment or electrode, which electrical potential is predetermined to be less than the activation voltage of the liquid crystal material.

Filed: 1975-05-22
Abstract: The ante chamber is spherical and constructed in two parts whereby the lower part is tensioned in position in the cylinder head by the upper part which contains the spark plug. A transfer channel joins the ante chamber with the main combustion chamber at a tangent in order to promote a turbulance to the combustion gases to cause fuel particles to be thrown on to the ante chamber wall region close to the spark plug electrodes to assist combustion and cause a spiral flame front to spread down the overflow channel to the main combustion chamber. Two overflow channels which intersect at an angle of 90 deg. towards the main combustion chamber may be provided and the diameter ratio between the overflow channels and the ante chamber is 0.35 to 0.45. The ante chamber is provided with a water cooling channel in order to give a low nitric oxide exhaust emission.
