Patent DE-2500763-A1 (DE)
Title: Calibrating measuring system for oscillator noise - uses discrimination resonator FM by defined frequency beat and preset modulation frequency
Inventor: KOEHLER JUERGEN
IPC: G01R29/06
Filed: 1975-01-10
Abstract: The frequency noise of microwave oscillator is calibratingly measured by a system, having a bridge-like circuit with a signal output divider, a circulator, a balanced mixer-detector and a microwave resonator. In order to calibrate the frequency noise to be measured a high-Q discriminating resonator is modulated rapidly with a defined frequency beat and preset modulation frequency. Preferably the frequency noise detected by the mixer-detector (9), amplified (10) and indicated in a frequency-selective volt meter (14) is compared with a sinusoidal calibrating signal, appearing at the mixer output when the resonance frequency of the resonator is modulated.

Title: Electronic starter for asynchronous single phase motors - with squirrel cage rotor and auxiliary starting winding
Inventor: ROSENFELDT WOLFGANG
IPC: H02P1/44
Filed: 1975-04-30
Abstract: The starting winding provides a phase shifted current. The starter has a time or current controlled switch for the auxiliary winding disconnection at the end of starting period. Switching off and on of the auxiliary winding is done by a triac (6) inserted into the auxiliary winding circuit controlled by a programmed time switch, and by self-triggering of the time switch during the main winding connection, when the triac (6) is made conducting and connects the auxiliary winding. When the time switch disconnects, the triac is extinguished and disconnects the auxiliary winding during next zero crossing.

Title: Negative brightness values display - involves scanning of film transparency by image of spot on CRT screen and feeding inverted signal to brightness control
Inventor: FLAMM PETER
IPC: H04N1/10
Filed: 1975-07-04
Abstract: The system may be used to display negative brightness value and complementary colours of a colour picture on a developed film. The pattern on the screen (7) of a T.V. receiver (1) is projected by a lens system (6) on the film (8) so that the film is scanned by an image of the spot on the T.V. tube. Light passing through the film is concentrated by a lens (9) on an electronic photosensitive component (10) in the focal plane of the lens (1). The amplified output signal from the photosensor (10) is applied to the aerial input (4) of the T.V. receiver through an h.f. stage (12) which can be modulated, or directly to the video stage (3) so that an output signal corresponding to the film dark area brightens the corresponding point of the CRT screen.

Title: Resilient stretch sieve base with lightweight reinforcement - has tension members and folds fitted for even stretching
Inventor: HOPPE KURT
IPC: B07B1/48
Filed: 1975-11-29
Abstract: Sieve base of wear-resistant rubber or rubber-elastic plastics has a reinforcement comprising tension members (2) and tension folds (3) as in 24 61 237 wherein each end (4) of each tension member (2) can be passed through an opening (5) in the fold (3), and deflected round a ridge (6) associated with the opening (5). A retaining force which is inherent in the rubber or plastics (1) of the sieve base can be associated with the deflected ends (4) of each tension member (2) corresponds more or less to the tensile strength of the part of the tension member extending between the tension folds (3), in dependence on the length, shape and size of the angle of deflection of each end (4) of the tension member (2). In this way whilst the stretch resilient sieve base has a high capacity and oscillation ability the reinforcing tension members (2) which can be stretched evenly can be economically manufactured and fitted with the structural height and weight still being kept to a minimum.

Title: System for production of photographic copies - has series of flash discharge tubes operating independently and adjustable within certain spectral ranges
Inventor: HAMMEL PETER
IPC: G03B27/54
Filed: 1975-12-11
Abstract: The device produces photographic copies from a negative. The exposure and development of the copy take place during its passage through the copying device. A series of flash type discharge lamps provide the illumination source to make the copy exposure. The discharge lamps have a gas filling which produces a discharge in a spectral range suitable for the nature of the copy being produced. The energy produced by each individual discharge lamp may be separately set and adjusted. The adjustment may be carried out by a computer which assess the requirements of the negatives.

Title: Electric arc furnace charging - through central water cooled funnel in roof terminating above arc zone
Inventor: EVERTZ EGON
IPC: C21C5/52
Filed: 1975-12-17
Abstract: An electric arc furnace for a granular or pelletised charge of iron sponge, lime, etc. has above the arc zone a charging tube which protrudes into the furnace space. In the case of a three-phase furnace, this tube is arrange in the centre of the furnace roof and terminates at a distance above the arc which is determined by the angle of repose of the charge.

Title: Cable damper system preventing damage to suspended loops - uses arms to restrict lateral motion when stacker truck reverses to wall and causes cable to bunch
Inventor: MEISSNER WERNER ING GRAD
IPC: H02G11/00
Filed: 1976-01-07
Abstract: The cable damping system prevents a supply cable to a warehouse stacker truck or similar being damaged by the violent oscillations that usually occur when the truck reverses to its 'rest' position close to the wall and the cable as a consequence is suddenly bunched into tight loops that swing from side to side. The lateral swing of the cable is prevented by a pair of arms (9) extending out from the rear vertical frame (6) of the truck towards the wall (1). (The cable is supported by small runners (3) on a rail (2) fixed to the wall). A second pair of arms (11) may also be included to reduce the loading on the first pair.

Title: Extn. of juice from apples by diffusion method - with recovery of pectin from solid residue after treatment with lime
IPC: A23L2/04
Filed: 1976-03-13
Abstract: Extn. of fruit juice, esp. apple juice, by the diffusion method, with subsequent prodn. of pectin from the solid residue, is improved in that the wet solid residue is immediately treated with a substance contg. Ca2+ ions, pref. Ca(OH)2. The solid residue is then pressed, and subsequently neutralised with a gas, pref. CO2. The water squeezed out from the solid residue is filtered, purified by contact with an ion exchange resin and recycled. Use of the diffusion method on applies at lower temps. (e.g. 60 degrees C) gave solid residue. The treatment with lime prevents excessive dissolution of pectin. Method can thus be applied to the prodn. of acid juices such as apple juice having a pH of 3-3.5 (there was no such a difficulty with the extraction of juice from sugar beets because its pH = 7). Yields are increased by 20-40%. There is no difficulty with the disposal of wastes.

Abstract: Anti-crash device is for preventing a load dropped from a crane from causing damage, esp. a heavy load in a nuclear power plant. A vertically movable table is suspended from cables which pass over sheaves and down inside (vertical) tubes. Counterweights inside the tubes are attached to the other ends of the cables and are damped in their movement by liq. which fills the tubes. The tubes also act as vertical guide rods for the table. Pref., where the wt. is lifted over a cooling pond or tank, the tubes have communicating holes with the tank liq. The spacing of the holes decreases upwards, giving increased braking to the ascending counterweights. Simple, robust and reliable.

Title: Electronic regulation of irrigation system - using low press. induced in tube for switching supply with timed venting of tube
Inventor: SCHWEIGMANN KLAUS
IPC: A01G25/16
Filed: 1976-04-28
Abstract: Automatic irrigation of agricultural ground is affected by monitoring the moisture level using a ceramic cell and using the low pressure in a tube to switch a contact. The ceramic cell (3) is located on the end of a long tube (7) coupled to a water container over a valve (5). When the pressure falls, due to the ground drying, a relay (4) is switched to open the valve. any air bubbles in the tube are passed through to the water tank. This process is repeated periodically under the control of a timer.
