Title: A-D convertor operating with double integration - has circuit for separation of output and input signals including AND gate and transformer
Inventor: KLEEGREWE CLAUS DR ING
IPC: H03M1/00
Filed: 1975-07-24
Abstract: Control signals are applied to an integrator, and a comparator signal appears at the end of each integration for stopping a pulse counter or for transfer of the respective counter reading to a store, are transmitted as galvanically separate signals. Integrator control signal (XR) of n-times the frequency are applied to two inputs of an AND gate (G), followed by a transistor (T1) in series with a voltage source (U1) and primary winding (L1) of a transformer (U). Its secondary winding (L2) supplies a full wave wave rectifier (D1, D2) from which the integrator inverted control signal (XR) can be collected. A further transistor (T2), controlled by comparator pulses, is connected to the secondary winding (L2).

Title: Twin-probe controlled audio frequency signal system - indicates moisture and fertilizer content in soil samples using insulated conductor probes
Inventor: BOUGH BJORN N DE
IPC: G01N33/24
Filed: 1975-07-26
Abstract: The audio-frequency signal generating system is used to measure conductivity and dielectric properties of a liquid or liquid-containing material, esp. to determine moisture and fertilizer content of soil samples. Two probes are inserted into the material, the resistance and capacitance between the probes is measured, and audio-frequency signals are generated as a function of the measured values to indicate the properties being investigated. Pref. a reduction in capacitance with an increase in frequency corresponds to a low fertilizer content in moist soil. The insulated conductor probes (111, 114) are of similar dimensions and in the form of cylindrical rods with conical tips.

Title: High pressure plunger pump - has cylinder preloaded against pump pressure by shrinking into housing block
Inventor: HAMMELMANN PAUL
IPC: F04B53/10
Filed: 1975-07-30
Abstract: Plunger pump has a contactless sliding plunger within a cylinder, and has centrally arranged inlet and outlet valves. The pump can be opened within a wide pressure difference, for example of one in hundred, independently of a minimum pressure. The sealing between the plunger and the cylinder ensures a minimum of leakage losses. The cylinder is held in the pump body under a preload corresponding to the expansion forces due to the pumping. The pumping forces are transmitted into the plunger by a connecting rod arranged concentrically within the cylinder. The rod has spherical ends for ensuring universal alignment within the crosshead and within the piston. The cylinder is shrunk by pressure fit into the bore within the pump housing block to ensure preload.

Title: Rotary hydraulic chuck - has hydraulic fluid supply via rotary gland and set of feelers inside cylinder operating vane switch
Inventor: DORP HEINZ VOM
IPC: B23B31/30
Filed: 1975-07-30
Abstract: The cylinder (6) is fitted with a hydraulic fluid supply connection (9). The connection is of the rotary gland-type and is located on the rear face (4) of the cylinder. The cylinder face carries two holes through which feeler pins (1) extend into the cylinder (6). The two feeler pins are joined together by a switching vane (2) fitted with tensional springs (10) which tend to push the fingers into the cylinder. The rotary gland is fitted with fluid connections (8) and (7) opposite faces of the piston (11). By applying pressure through connection (7) piston (11) moves towards the feeler pins, which are arranged to ensure the correct position of the piston necessary for the chucking force. If the piston moves beyond that point it moves the feeler pins outwards and the vane switch operates control switch (3) which then cuts off pressurised media supply.
