Inventor: EXNER CHRISTIAN ING GRAD
IPC: G01S3/781
Filed: 1979-01-11
Abstract: The location and ranging system for flying objects, such as missiles or rockets in naval engagements uses a locating instrument (1) operating in the infra red range. It consists of an optical input system, an infra-red multi line detector, followed by a preamplifier, and an evaluation circuit to produce a digital signal. It will avoid any error signals produced by the sun. There is a second locating instrument (5) operating in the visible range. The field of vision of the second instrument corresponds to that of the infra-red instrument. The evaluation circuit (9) is connected both to the infra red and to the visible range locating instruments. The second locating instrument preferably is sensitive to light of wavelength corresponding to maximum distribution spectrum of colour light.

Title: Torque converter with improved gear ratio - has epicyclic gear with two sun wheels with firmly connected drive shafts
Inventor: PREGLAU OTTO DR MED
IPC: B66D1/14
Filed: 1979-02-27
Abstract: The gear between the converter input and output is preferably intended for a hoisting tackle. The gear is of epicyclic type (20) with two drive shafts (22, 23) coupled firmly to the gear sun wheels, and with a rotary annulus (11) to which the converter drive (17) is firmly coupled. One drive shaft (2) forms the converter drive, the other one (23) being connected to the annulus. The force thus transmitted to the annulus is of opposite direction to that of the planetary wheel drive cage (21). The cage and annulus operational connection is such that the peripheral force (46) engaging the annulus is = to peripheral force exerted by the respective drive shaft in opposite direction. Thus the drive shaft and the cage are mutually stressed, thus forming an equilibrium with a tongue engaging the other drive shaft.

Title: Electric hearing aid earpiece worn inside ear - transmits sound through inflated balloon inserted in ear canal
IPC: H04R25/00
Filed: 1979-04-05
Abstract: The sound output of a hearing aid is conducted along a tube to the earpiece. The end of the tube is attached, e.g. by adhesive, to a small inflated balloon which is inserted well into the ear canal. A plug, moulded to fit the ear canal opening, supports the tube and locates the balloon. Because of its internal pressure, the balloon fits closely in the ear canal. Its end surface forms a membrane across the canal and transmits sound through the intervening air space to the ear drum. The balloon material, size, internal pressure, and position in the canal are all chosen by an audiologist to suit the patient.

Title: Pressure reducing valve with impeller control - has throttling action produced by impeller that rotates to perform work
Inventor: WENZEL-EDEN HELMUT
IPC: F03B15/00
Filed: 1979-10-23
Abstract: The pressure reducing valve for pneumatic or hydraulic systems is designed to utilise the energy dissipated in the reduction process. Flow occurs between an inlet and outlet over a throttling section provided by a valve orifice (2). The effective area of the orifice is varied dependent upon the required pressure level, by the position of an impeller (3) that is rotated by the fluid flow. The power developed by the impeller is used to rotate a shaft that may be coupled to an auxiliary unit to perform work. The pressure setting of the reducing valve is controlled by pressure applied to a diaphragm (19) control stage.

Title: Load sensitive brake pressure valve - includes variable setting inertial mass to alter braking distribution
Inventor: SEKIGUCHI YUKICHI
IPC: B60T8/30
Filed: 1979-11-13
Abstract: The modified load regulated hydraulic brake pressure valve is used for the rear wheels of a road vehicle in which the inertial mass (11) is mounted in a pivoted support inside the valve (10). The support tilts with the brake reaction so that the inertial effect is adjusted to the rate of application of the brakes. The system provides optimum brake response so that wheel lock is prevented. It enables the vehicle to be effectively braked over a wide range of loadings as well as over a wide range of brake application rates.
Patent DE-2945864-A1 (DE)
Title: Electronic speed control for folding machine belt transporter - automatically matches belt speed to ironing machine speed
IPC: H02P5/50
Filed: 1979-11-14
Abstract: In a folding machine for laundered articles having a belt transporter working in conjunction with a preceding ironing machine, the speed of the transporter is adjusted to correspond to the speed of the ironing machine by an electronic control circuit in which a pulse generator attached to the ironing roller produces in a digital-analogue transducer a reference voltage. A tachogenerator connected to the motor produces a signal proportional to the actual motor speed, which is compared to the reference signal in a control amplifier, and the resultant signal regulates the trigger of a triac which controls the speed of the motor. This gives rapid and accurate matching of the transporter speed to an accuracy of 0.1% or better.

Title: Composite window or door section of aluminium and PVC - has points at intervals along connecting ribs to prevent longitudinal sliding
Inventor: KLEISS JOACHIM ING GRAD
IPC: E06B3/263
Filed: 1980-04-02
Abstract: Extruded aluminium section for windows or doors has a PVC section clamped alongside it by a projection-and-groove type connection. The surface of the aluminium section has longitudinal projecting ribs of triangular cross-section; the apex of the rib is cut back at intervals along its length to leave projecting points, which penetrate into the opposite surface of the PVC section when the latter is fitted to the aluminium section. Pref., the ribs are spaced apart at least by the thickness of the aluminium wall and the depth of a rib does not exceed the thickness of this wall. In a pref. embodiment, the projections of the ribs also act as hooks for engaging into the grooves of the PVC section. This arrangement has the advantage that differences in the coefficients of thermal expansion of the aluminium and the PVC cannot result in relative longitudinal movement of the two sections, since the peaks of the ridges on the aluminium side act as anchors at intervals along the PVC side.
Patent DE-3016082-A1 (DE)
Inventor: BETZL HERMANN DIPL ING
IPC: H03H15/02
Filed: 1980-04-25
Abstract: The invention relates to an electrical filter circuit operated with a definite sampling and clock frequency fT, such filter being made up of CTD elements, and having at least one bipolar or quadripolar resonator in the form of a self-contained conductor loop (for example, C1, C2) with unidirectional transmission behavior. Differences in the transfer capacitances of such circuits are reduced, as far as possible, in order to thereby simplify integrated manufacture as far as possible, by positioning the frequency band to be filtered out at a frequency position which lies above half the clock frequency (fT/2), or in the range from fT/2 through 3fT/2.

Title: Combined gas and steam turbine plant - has gas combustion chamber in water drum, with resultant steam applied to turbine with exhaust gas
Inventor: OTREMBNIK MAX
IPC: F01K23/06
Filed: 1980-05-07
Abstract: The combined gas and steam turbine plant has a hemispherical water-cum-steam drum housing a combustion chamber connected by ducting to gas chambers. The heat from light fuel burnt in the former spreads to the latter and thence into the water to generate steam. Separate gas and steam pipes from the drum lead to separate but adjacent spacers where energy from the two mediums is applied to the turbine. The hotter gas reheats the steam via the common space boundary, permitting further application of both to the turbine after extraction from points opposite the inlets to the first spaces.
