Patent DE-2823850-A1 (DE)
Title: Target position and speed detection - is performed by transmission of two frequencies and measuring reflected signals
Inventor: NEIDELL NORMAN S
IPC: G01S13/06
Filed: 1978-05-31
Abstract: Position and speed of a target is determined from reflection of signal comprising two frequencies. Time difference between transmissions is known and processing of received signals enables noise and signal dispersion effects in transmission medium to be overcome. A signal comprising two frequencies is transmitted to a target. These signals have a known initial difference in time of transmission. Signals reflected from a target are separated and the time is determined from initial transmission for both frequencies to determined target velocity components using correlation techniques. Corrections are applied to each transit time for the two transmission frequencies to determined target distance.

Title: Catalytic oxidn. of sulphur di:oxide to tri:oxide - in sulphuric acid mfr., by double conversion using wall heat exchange to increase heat exchange intensity
Inventor: SZUMILAS CZESLAW DIPL ING CHEM
IPC: C01B17/765
Filed: 1978-06-22
Abstract: Catalyst oxidn. of SO2 to SO3 in H2SO4 mfr. by double conversion, with intermediate absorption, involves contacting the SO2-contg. gas and O2 with a V catalyst at elevated temp. in a chamber with >=3 oxidn. levels, the first forming the first oxidn. stage and the others the second oxidn. stage. Part of the SO2 stream is introduced at each level, whilst the SO3 formed in the first oxidn. stage is absorbed and the gas leaving the absorption stage is heated in wall heat exchangers and passed to the second oxidn. stage. The SO2 formed in the second stage is absorbed in the final absorber, from which a gas with a low SO2 content is discharged. The novel features are as follows, the gas passed from intermediate absorption to the second oxidn. stage is heated in 2 stages, first by the gas from the past plate of the first oxidn. stage and then by the gas from the preceding plate of this stage. The gas passed to intermediate absorption is cooled first by the gas passing to the second conversion stage and then by air passing to the combustion of S. More intensive heat exchange is attained, whilst the size and wt. of the heat exchanger and current consumption are reduced.

Title: Anti-salt protective film for plants - consists of colourless, sprayed on coating which disintegrates under light
Inventor: BRITSCH WALTER
IPC: A01G13/00
Filed: 1978-09-07
Abstract: The anti-salt protection film is a water-soluble form and can be sprayed for protecting bushes, trees, hedges etc. from damage from salt spread on roads or from seal salt. An almost colourless, adhesive coating is disintegrated under light without any residue and a temporary protection for the plant is achieved e.g. in winter.

Title: Sets of rollers for holding edges of moving cloth flat - use cylinder to regulate relative centre position and to produce constant tension in cloth
Inventor: STANGNER WERNER DIPL ING
IPC: D06C3/06
Filed: 1978-12-12
Abstract: A cloth width (1) moves towards a winding drum and ensures that both edges are flat, each one is located by sets of three rollers (4, 5, 6). Each roller has its individual drive and the outer two are of fixed location in a common bearing plate (3). The centre roller (5) is located on a swivel mounting (17) so that it can partially circle about the outer fixed roller centre (4). A crank lever (10) operated by a pneumatic cylinder (11) provides for swivel mounting (17). This produces a constant cloth tension with the resilience of an air spring.

Title: Drive system for magnetic tape cassettes - has clutch guide and contact rollers enabling differential tape and endless loop cassettes to be used
Inventor: TAUSCHER WOLFGANG
IPC: G11B15/29
Filed: 1978-12-14
Abstract: A drive system for magnetic tape cassette - where the spools are not directly driven - provides operation with either endless tape loop cassette types or differential tape cassettes. For differential tape cassettes only the tape is driven by a contact roller (6) sandwiching the tape against the drive shaft (1). At the same time guide rollers (10, 8) ensure that the tape is maintained in contact with the recording and playback heads (2, 3). For use with endless loop tapes the cassette has the tape located over a guide roller and requires that contact drive roller (6) is moved to cause the tape to contact the drive spindle. To provide for both types of cassette the shaft (4) is produced with a clutch that is only engaged when a differential tape cassette is used.

Title: Coin operated dispensing machine with several goods columns - each having article forwarding device acted on by forwarding and return ramps
IPC: G07F11/10
Filed: 1979-01-22
Abstract: The goods dispensing machine has a selector, via which an article held in one of several adjacent dispensing columns is selected, each column having a forwarding device for removing the bottom article from the stack. The forwarding device is restrained by a retainer with a relatively energised release device for the holder. This allows the forwarding device to be released and to be engaged by a ramp face pushing it in the dispensing direction. The forwarding device is returned to its initial position by a second rump face beginning a given distance after the end of the first one and pushing the forwarding device in the opposite direction. Pref. the retainer uses a permanent magnet, which is selectively released via an electromagnet.

Title: Circuit measuring voltage drop across switch - caused by current in prim. winding of ignition coil of IC engine
Inventor: JOERG MANFRED
IPC: F02P17/12
Filed: 1979-02-22
Abstract: The measuring circuit has the connection (KL1) between the ignition coil's primary (1) and the switch (2) that interrupts the current through the primary connected to the input of a pulse shaper (6) and to the input of a voltage transformer (12). The transformer's output is switched by a first switch (8) through to a first storage capacitor (10) whose output side is coupled via a second switch (9) to a second capacitor (11). The first and second switches are controlled by a circuit (7) connected to the pulse shaper's output and are alternately opened and closed so that charge is transferred from the first capacitor to the second. The first capacitor is, e.g. 50 times, larger than the second. The voltage across the second capacitor is converted into a digital signal describing the voltage being measured.

Title: Mechanical oil application to dough - directly through hole in dough kneading disc
Inventor: LIPPELT JUN WILHELM
IPC: A21C7/00
Filed: 1979-05-14
Abstract: An oil or fat containing substance is worked into the end of divided pieces of dough during the mechanised kneading operation. This is done in a kneading station, 90 degrees removed from the charging and the discharging station, by an eccentric kneading disc to which the liq substance is applied. A dividing drum has four chambers at 90 degrees from each other and is revolved in steps of 90 degrees at say 25 rev/min. A lump of dough is cut off by a blade. This keeps losses of the liq substance (and contamination caused thereby) to a minimum. The appliance is simple and easy to operate and to maintain.

Title: Heat treatment chamber - with roller chains feeding belt conveyor in corrugations for continuous turning of articles (AT 15.7.80)
Inventor: SPIRIN EVGENIJ TIMOFEEVITSCH
IPC: F26B15/18
Filed: 1979-06-29
Abstract: Plant for the heat treatment of cylindrical articles, specially of sausages, consists of an endless belt conveyor which takes the articles through the treatment chamber, equipped with e.g. infrared radiators. Within this chamber, the belt is gripped at both selvedges by rollers on a pair of endless chain drives, one above the belt and one below which are staggered and deform the belt into a wavy strip. The belt conveyor and the chains are driven by separate motors and at different speeds. The differential speed causes the sausages which rest in the corrugations to be constantly turned so that they are heat treated uniformly on all sides. Articles of different diameters can be treated and the treatment causes no deformation.
