Patent DE-2154415-B2 (DE)
Title: Voltage to frequency converter - has high resolution with increased accuracy and speed of indication
IPC: H03M1/00
Filed: 1971-11-02
Abstract: A voltage to frequency converter has a capacitor charged and discharged between two preset voltage levels under the control of a bistable switching circuit (F1). In addition the bistable circuit controls two AND gates (G1, G2) for the forwards and backwards counting inputs of a slave converter for the capacitor voltage (after amplification is necessary). The outputs of the gates are connected through a NOR gate (G3) at the output of which a pulse train appears with frequency proportional to the input voltage. The converter resolves the flanks of the charge voltage into short time intervals whose mean frequency is proportional to the input voltage so that the converter has a finer resolution, is more accurate, and faster in operation as compared with conventional converters.

Title: Hydraulic control valve piston - has auxiliary piston with conical throttle holes to damp movement of main piston
IPC: F16K31/122
Filed: 1971-11-13
Abstract: The hydraulically operated control valve comprises a valve piston with spring-acting return guide, and an auxiliary piston fitted to the opposite side of the valve piston to that where the spring action is effective. The auxiliary piston forms a throttle cross-section for damping the valve piston movement in the cut-off direction. The auxiliary piston (11) is displaceable on a bolt (10) screwed into the valve piston (1). Between the auxiliary and valve pistons a spring (12) is inserted and counterposed recesses (14, 15) in the valve and auxiliary pistons form a chamber. Throttle holes (17) in the auxiliary piston (11) are conical, widening in the direction of flow.

Title: pneumatic antiblocking brake system - includes reserve high pressure air reservoir to achieve rapid response time
IPC: B60T8/36
Filed: 1972-04-20
Abstract: The anti-blocking pneumatic brakes have a relay valve to control the brake pressure in response to the operation of two control valves, operated by solenoids. These control the flow of air as well as the venting of the brakes. A flow restriction ensures a controlled pressure change while a balancing chamber is coupled to the control system by a non-return valve. This is coupled to the system after the flow restriction and ensures asymmetric venting and pressure application characteristics. It also ensures that the braking cycle can be interrupted at any state of the anti-blocking sequence.

Abstract: A hermaphroditic coupling system, especially for an optical fibre (or electrical) connector member. The connector member 10 has a body 12 with a cylindrical portion 14 and a semi-cylindrical extension 16, defining a stepped end profile comprising rearward and forward spaced parallel semi-annular transverse surfaces 24, 26 and a planar portion 22 between them, this structure having 180 DEG  rotational symmetry about a transverse axis 56. A channel 20 is formed in the extension 16 as a continuation of a bore 18 in the portion 14 forming a recess. A boss 32 is in the channel 20 and has a projecting end 34 projecting forwardly of surface 26. A domed abutment surface 44 on an abutment member 42 resiliently mounted by a spring 40 at the rear of the boss faces rearwardly towards the bore 18. The space 50 between the boss 32 and the end surface 24 of the body portion 14  is sufficient to receive laterally the boss on an opposed identical connector member 58 when the abutment members are depressed. When the connectors are axially aligned they move together longitudinally under the action of the springs 40 to engage the projecting end 34 of the boss 32 in the end of the bore 18. The connector member is of simple construction and can provide both a snap-in and a snatch-release capability.

Abstract: The invention relates to a device for continuous monitoring of the concentration of at least one gaseous component in gas mixtures. A disadvantage with known devices is, however, their complex construction, their high energy demand, their large spatial requirement and, as a result of the large mass, inhomogeneous temperature distribution, with the consequence of measurement inaccuracies, and their inertia, especially in the starting phase. The disadvantages with the prior art are avoided in the device according to the invention in that a support is designed as a lamina, on one side of which at least two electrodes are applied as mutually separated thin films, in that, on one side of the ceramic wafer, a temperature sensor separated from the electrodes is furthermore applied and in that, on the other side of the lamina, an electrical heating resistor film is provided for heating.
