Title: Packing carton made from single sheet - has corner members folded into straight prismatic shape at wall ends
Inventor: LAU PETER
IPC: B65D5/00
Filed: 1978-04-17
Abstract: The packing comprises a single sheet cut to form base, and side and end walls, particularly of corrugated paper or cardboard. At the ends of the side (4) or end walls hollow corner members (16) are formed, each folded into a straight prisma tic shape. In the erected state these are self-supporting, and are joined to the end or side walls as the case may be. The members can be of square, rectangular or triangular section, and formed by extensions on the wall ends. They are folded into shape while the sheet is still flat and secured in position to their respective walls, typically by gluing.

Title: Impeller type gas meter with automatic loading adjustment - uses spring-loaded sliding bearing and axial bearing for higher loads
Inventor: CICHOWLAS KARL
IPC: G01F1/10
Filed: 1978-05-19
Abstract: The gas meter uses a special bearing arrangement which allows different axial forces due to the impeller to be handled provides long service life and a wide measuring range. Up to an axial force of say 8kg. only the journal bearing is loaded. A spring is moved with all the moving parts via the sliding bearing against an axial bearing. The bearing ring of this bearing is held loosely in a housing, the ball bearings having approx. 0.2 mm play. The impeller has a radial slip ring of PTFE/bronze to prevent jamming. The first bearing cannot therefore be loaded to a value greater than approximately 8.5 kg. The device withstands high loads without affecting the light action at low pressure and flows.
Patent DE-2823110-A1 (DE)
Inventor: SHIDA MASAHARU
IPC: H02P8/02
Filed: 1978-05-26
Abstract: An electronic timepiece includes a stepping motor having a coil and a rotor. Circuitry is provided for generating and applying alternating pulses to the motor coil to effect forward stepwise rotation of the motor rotor in a forward direction and for generating and applying alternating pulses to the motor coil to effect reverse stepwise rotation of the motor rotor in a reverse direction. The reverse rotation is achieved by sets of three alternating pulses with the first pulse of each set effecting incremental angular movement of the motor rotor in the forward direction followed by the second and third pulses which effect greater icremental angular movement of the motor rotor in the reverse direction to thereby obtain for each pulse set a net angular movement of the motor rotor in the reverse direction.

Title: Caulking compsn. for sealing leaks in tanks, pipes - obtd. by mixing an epoxy! resin and wax with a mixt. of hardener and wax
Inventor: LYTTON DONALD B
IPC: C09K3/12
Filed: 1978-06-23
Abstract: Caulking compsn. is claimed for sealing leaks in tanks and pipes contg. liqs. flowing under low pressure. The compsn has initially the consistency of a mastic during its prepn and is formed by mixing its components (A) and (B) each having a mastic consistency. component (A) is a mixt. of an epoxy resin which is normally liq. and a wax or waxy material. (B) is a mixt. of a liq. hardener for the resin and a wax or waxy material. The amt. of wax(y material) used is such that when (A) and (B) are mixed in predetermined amts. and applied into a crack, the resulting compsn. seals the leak soon after its application well before the resin has completely hardened. Used partic. for sealing leaks in tanks and pipes for fuel, kerosene, oil, water etc. flowing under a pressure of 0.35-0.70 kg/cm2 e.g. in aircraft wings. The compsn. acts as a temporary sealant which is effective for 4-10 hrs until a permanent repair can be effected.

Patent DE-2922861-A1 (DE)
Title: Coking coal compacting - by projection into mould through blades of centrifugal impellers, reduces machine stresses
Inventor: VEIT GERD DIPL ING
IPC: C10B45/02
Filed: 1979-06-06
Abstract: A fine-grained coal blend which is to be used for charging coke ovens is compressed by transferring the coal blend from a continuous conveyor to one or more impellers, each with one or more blades. The impellers revolve opposite to the direction of free fall of the coal particles so that they are compacted into clumps. The centrifugal force accelerates the clumps and projects them into a compression mould, thus effecting a further compression by impact. Several impellers can be arranged on the same drive shaft, or several shafts, each with one or more impellers, can be arranged in parallel one after another. This method produces much less noise than the conventional stamping system. It results in less high stresses for the machine and mould use for the compaction; large quantities of a coal blend can be compressed in a very short time.
Patent DE-2925631-A1 (DE)
Title: Line transformer coil former for TV receivers - has separate coil segment compartments with interconnection channels formed to minimise voltage bridging
Inventor: REICHOW WOLFGANG
IPC: H01F5/02
Filed: 1979-06-26
Abstract: The line transformer for television receiver applications uses interconnected winding segments located in separate cavities to provide high voltage stability. The transformer core (1) has a central bore and a number of disc segments (3) to form separate winding cavities (4). The individual windings have interconnections and external connection is made via two terminals. The interconnections are made in slots (6) within each disc periphery and the slots are set at an angle of 15 degrees and alternate in the direction along the former. Due to the length of the air gap provided by the slots, the possibility of voltage bridging is minimised.

Title: Heating ready-to-use food wrapping - after water and or glycerol absorption but before storage to improve biological stability
Inventor: WITZLEBEN JOB W V DIPL CHEM
IPC: A22C13/00
Filed: 1979-06-30
Abstract: The prodn. of natural and/or regenerated cellulose food wrappings which can be stored in a ready-to-fill condition and contain sufficient water and/or glycerol to allow direct processing after storage, comprises heating after water and/or glycerol content absorption but before storage in a sterile pack. Heating can take place by high frequency energy. In a specific embodiment, over-pressure is applied to increase temps. Cellulose wrappings, contg. no internal or external lacquer coatings are heated in a germ-impermeable foil pack which is hermetically sealed only after the air in the wrapping is displaced by the emerging vapours. Process applicn. to glycerol-free wrappings, e.g. sausage skins, contg. 5-100% water, is claimed. The wrappings can be stored without risk of damage by fungi, spores and bacteria. Energy -consumption in sterilising can be reduced, e.g. by 25%.

Title: Transmission system with extra data in TV signal - by modulating onto auxiliary carrier-wave and then modulating onto main carrier
Inventor: HANSEN JENS DIPL ING
IPC: H04H20/48
Filed: 1979-12-01
Abstract: The transmission system produces an auxiliary carrier-wave onto which the extra data is modulated using a single sideband method. The SSB modulation product resulting from the auxiliary carrier is modulated along with the television data onto the main carrier-wave. The auxiliary carrier can be suppressed after being modulated. The auxiliary carrier is derived from the line frequency of the television signal being transmitted and has a frequency three to four times that of the line frequency. The advantage lies in being able to send data covering a large bandwidth.
