Filed: 1973-09-21
Abstract: A pressure control device for a flowing fluid medium is described which comprises a fluid inlet conduit structure and a fluid return conduit structure each of which conduit structures has a valve seat a connecting structure for linkup with a fuel consuming device and a movable valve member for controlling the cross sectional area of the outflow of fluid from the control device, wherein the movable valve member which is arranged between the valve seats of the inlet and return conduit structures, controls the cross sectional areas of flow through the inlet conduit structure and the return conduit structure, respectively, in opposite sense and is biased by a resetting force, and wherein the valve seat cross sectional area of the return conduit structure is smaller than that of the inlet conduit structure, whereby a force resulting from the inlet fluid pressure and the cross sectional flow area of the inlet conduit structure acts on the movable valve member in a direction causing reduction of fluid influx and is opposed by the resetting force as well as by a force resulting from the fluid pressure in the connecting structure and from the area difference between the valve seat across sectional areas of the inlet and the return conduit structures. The movable valve member is preferably a membrane, and an electromagnet or spring structure may be used to provide the resetting force.

Title: Compander for TDM telecommunication system
IPC: H03M1/58
Filed: 1974-05-21
Abstract: Amplitude samples of voice signals to be transmitted by pulse-code modulation are compared with a quasi-exponential reference voltage generated during each sampling interval while a binary counter receives a train of isochronous clock pulses, the reading of the counter at the instant of a match being stored in a memory for subsequent insertion into a message frame. Positive and negative signals are distinguished by a sign bit preceding the amplitude code in one embodiment the reference voltage is sequentially generated with opposite polarities in successive halves of a sampling interval, the counter having an additional stage to generate the sign bit. Decoding at the receiving end is achieved with the aid of another binary counter whose output is compared with the amplitude code and, in the event of a match, causes the instantaneous value of a similar reference voltage to be sampled and stored for subsequent integration.

Title: Power control hand truck
IPC: B62B1/14
Filed: 1974-07-02
Abstract: An electrically powered, two wheeled hand truck having telescoping frame parts, the inner frame part being raised and lowered by electric power means in the form of a rotatable screw shaft which engages a bearing nut fixed to the inner movable frame part. Rotation of the screw in a particular direction either lowers or raises the inner frame part. A DC motor is carried by the hand truck and powered by a battery voltage source also carried by the hand truck. Electrical switching means select the direction of rotation of the screw shaft for lowering or raising the inner movable frame part. Rapid and accurately controlled raising and lowering allows moving a load carried on the movable frame part from a raised position to a lowered position and vice-versa. A braking means holds the screw shaft when the motor is turned off so that the load does not slip. Starting the motor overrides the braking means to either raise or lower the load.

Title: Tracking mirror device for a video disc player
IPC: G02B7/18
Filed: 1976-10-13
Abstract: A tracking mirror device, in particular for a video disc player, in which for following an information track on a video disc with a beam of radiation, use is made of a mirror which oscillates at a high frequency, which causes the beam of radiation, which serves for scanning the information track, to oscillate transversely to the information track at a high frequency and a small amplitude, while the filtered out high-frequency signal, as a function of its amplitude and its phase relationship with the high frequency voltage which is applied to the oscillating mirror, yields a control signal for following the information track. In accordance with the invention, use is made of an oscillating mirror which is driven electromagnetically and which is connected to oscillation compensation elements by means of springs which elements oscillate in phase opposition to the mirror. Thus, an oscillator mirror is obtained which can readily be excited to natural resonance and thus requires little power. On the mirror a piezo-electric miniature acceleration transducer can be mounted, which can provide a feedback signal so that the oscillating mirror can be included in a self-oscillating circuit.

Patent ES-463496-A1 (ES)
Title: Variable speed reversible drive for a harvesting apparatus
IPC: A01D69/06
Filed: 1977-10-25
Abstract: An agricultural crop harvester's feeding and gathering units are driven by a power source on the harvester through a sheave assembly journaled on a countershaft mounted towards the rear of the feeding unit. Power is thence transmitted by a variable ratio V-belt drive to a speed reducing and direction reversing planetary gear unit mounted forwardly on the feeding unit and finally to the gathering and feeding mechanisms by drives of conventional design. In the variable ratio V-belt drive, the effective diameter of a split sheave output portion of the countershaft sheave assembly is selectively adjusted hydraulically while, in inverse response, the effective diameter of a spring loaded variable driven split sheave, integral with the planetary gear unit, adjusts automatically. In addition, the driven sheave is provided with a coaxial cam arrangement responsive to changes in torque transmitted so that its effective diameter also adjusts automatically to provide appropriate belt tension. Interposing a speed reducing planetary gear unit in the drive system following the V-belt drive makes possible the use of comparatively higher belt speeds and smaller sheave diameters and facilitates provision of a selectively reversible drive to the gathering and feeding units. The reversed speed of rotation of the output of the planetary unit is substantially lower than its forward speed.

Title: Reference electrodes and measuring systems for detemining the amount of disolved oxygen in a liquid
IPC: G21C17/022
Filed: 1978-08-01
Abstract: The high-temperature reference electrode (10) is used in a measuring device for determining the oxygen content of water at very high temperature. At one end it has a sealed tube (12), preferably made of a palladium-silver alloy. The latter is pressurised with hydrogen from a feed line (18) and is loosely enclosed in a perforated sleeve (14). Through openings (16) in the sleeve, water enters the narrow gap between the tube (12) and the sleeve (14), is retained in the gap and is saturated with hydrogen, which diffuses through the wall of the tube (12). This provides a constant value which serves as a reference level for the measurements of oxygen content carried out together with a measuring electrode. The reference electrode is used in boiler construction, mainly in nuclear reactor boilers.
