Patent DE-2631760-A1 (DE)
Title: Closure for ointment tube - has piston and closure cap and is actuated by slight rotation
Inventor: KUMM ERWIN
IPC: B65D47/24
Filed: 1976-07-15

The closure is opened or closed by slight rotation and is easily dismantled for cleaning and reassembly.
Patent DE-2634022-A1 (DE)
Title: Bag filter for dust separation from air - has rigid mounting on dirty side and flexible mounting on clean side
IPC: B01D46/00
Filed: 1976-07-29
Abstract: Filter has a series of filter pockets arranged in a housing using an air back flush to clean them. The clean air side sealed from the dirty side. The filter pockets are rigidly mounted to the housing on the dusty air side. On the clean air side the mounting is to a base plate. This mounted inside the housing by rollers and the purge air jets are fixed to this. To this plate separation walls are mounted next to each other. The pockets are partially tensioned over these and sealed. They are covered by an elastic housing. The outer pockets have an inflatable bag or flexible wall arranged alongside them. Several pockets can be formed from one piece of fabric arranged in groups. Used for filter dust laden gas streams esp. where combustible dusts are involved. Spring tensioned systems to improve cleaning are known but have problems. The filter described is fully elastic in itself this being independent of the degree of fouling or the pressure depression so that adequate cleaning always occurs.

Title: Concn. and purificn. of sulphuric acid contg. organic cpds. - with introduction of oxygen, reducing nitric acid consumption and sulphur di:oxide emission
Inventor: FLORIAN WERNER DIPL CHEM DR
IPC: C01B17/90
Filed: 1977-07-13
Abstract: In the treatment of H2SO4 contaminated with organic cpds. by concn. to 50-100 wt.% acid, followed by treatment with HNO3, the concn. acid is treated simultaneously with HNO3 and/or a soln. of nitrosylsulphuric acid in H2SO4 and gases contg.

Title: Marine acoustic echo depth sounder with digital display - times echo of transmitted pulse via gating network and threshold detector
Inventor: SANDER KLAUS ING GRAD
IPC: G01S15/14
Filed: 1977-07-21
Abstract: A marine echo sounding equipment for determining the depth of water under a ship has a digital display and depends on a time gating and threshold network to extract the correct echo signal fron noise. The equipment consists of a transmitter and acoustic transducer, a receiver stage and associated threshold detector, a gating network and a digital display. The gating network essentially inhibits the receiving array during a fixed period after a pulse is transmitted, so that extraneous signals from the transmitted pulse the propeller, and water turbulence are ignored. It contains an oscillator, monostable multivibrator and a number of gates. The display is actuated by a transmitted pulse and is incremented until a gated echo pulse is monitored. It then stops, indicating the water depth.

Title: Automatic tuning circuit for TV receiver - approaches wanted station from both directions at progressively reducing tuning speeds
Inventor: MINNER WILLY ING GRAD
IPC: H03J7/28
Filed: 1977-11-02
Abstract: The automatic tuning circuit is designed for use in a TV receiver. It has a circuit to control coarse and fine tuning. The control circuit generates a relatively fast sweep signal for coarse tuning and a slower one for fine tuning. The changeover from coarse to fine occurs when the wanted frequency is first detected. The circuit then fine tunes backwards towards the wanted station. When the wanted station is again detected fine tuning reverses again to move forwards but at a lower speed. This approach is repeated a fourth time before terminating.

Title: Phase jitter compensator for digital transmission - prevents systematic jitter affecting clock signal retrieval by subtracting compensating signal from delayed signal
Inventor: TROENDLE KARLHEINZ PROF DR ING
IPC: H04L7/02
Filed: 1978-02-01
Abstract: The phase jitter compensator, for digital transmissions derives signals from the receiver's (or regenerator's) output for use in eliminating systematic phase jitter such that systematic disturbances, e.g. pulse cross-talk, have no effect on the retrieval of the clock signal. The non-noisy part of the received signal at the wanted zero position is subtracted as a compensating signal from the delayed received signal.
