Patent DE-2807929-A1 (DE)
Title: Haemostatic agent for body cavities e.g. nostrils - contg. foam-forming substances or a propellant gas
Inventor: TOROSSIAN FERNAND DR MED
IPC: A61K45/08
Filed: 1978-02-24
Abstract: New haemostatic medicaments for introduction into and packing of cavities in living bodies contain a foam-forming substance and a propellant gas. The Haemostatic agents are partic. for stopping bleeding in human body cavities, e.g. in nasal passages or cavities, ears, the uterus, or even the gastrointestinal tract. The effectiveness of the medicament is attributed to the cooling effect of the foam, which causes vasoconstriction and therefore reduces blood flow and stops bleeding. The vasoconstricting effect is also useful in localising the effects of local anaesthetics, so that the compsns. are also useful as carriers for local anaesthetic agents.

Title: Self-repairing power capacitor - has metallised second dielectric as bottom layer of main dielectric carrying plates on other side
Inventor: TSCHATINJAN JURIJ SMBATOVITSCH
IPC: H01G4/015
Filed: 1978-05-24

Title: Oil gasifying burner with starting flame stabiliser - has perforated mixing tube holding air velocity below flame propagation velocity
Inventor: KEHL ALBIN DIPL PHYS DR
IPC: F23C9/00
Filed: 1978-09-09
Abstract: The burner has atomising nozzle in air supply tube. The atomised fuel passes through an orifice in plate closing the air supply tube combustion chamber end. Fuel is gasified in mixing tube enclosed by a flame tube which carries recirculating combustion gases. Air is supplied without special regulator due to the flow of combustion gases and hence flame is maintained on starting and runiing. The mixing tube (8) perforations allow flow of combustion air into the space between mixing tube and flame tube (7) on starting before the recirculation is established. The combustion air is supplied through orifice (3). The mixing tube can be made of wire mesh. The fuel may be preheated in or upstream of the atomising nozzle (4). The air flow velocity is automatically maintained below flame propagation velocity on starting.

Title: Front mounted attachment for tractor - is fitted on linked struts to pivot with steering
Inventor: GEGO ARNO DR ING
IPC: A01D75/30
Filed: 1978-09-30
Abstract: The front, steered axles of the tractor (1) is fitted with linked struts extending in front of the vehicle and supporting working attachments. The struts pivot with the steering so that the work can be steered around plant rows etc. The system ensures that the working attachments, e.g. grass cutters, operate in front of the wheel before the crop or the ground is flattened under the wheels. For grass cutting the modification eliminates the rows of uncut grass which spring up after being flattened.

Title: Plank feeder system for edge processors - has transverse conveyor with integral slide surfaces for plank transverse motion
Inventor: FORNELL ERIK GUNNAR
IPC: B65G47/74
Filed: 1979-02-19
Abstract: The feeder is for planks having untreated edges. During transverse conveyance, the planks are measured on the conveyor, and the results evaluated, by a computer, to achieve optimum yield by an edge processor. The planks reach a combined centering- and side adjusting unit and feeder, and then pass in a longitudinal direction through the processor. The transverse conveyor (10) moves the untreated planks (12) onto retractable slide surfaces (15, 16), where they are supported during centering and side adjustment. The slide surfaces are then removed, and the planks deposited onto a longitudinal conveyor to be moved into the processor.

The printed conductors and components are spaced at equal distances from the centre line allowing for joining with wire bridges (13) secured by dip soldering. The connectors are parted at the mid-line when the board is divided to provide two similar p.c.b.s. This is facilitated by openings (7) separated by bridge pieces (8) symmetrically located w.r.t. the mid-line.

Title: Leached glass fibres with high silica content - where fibre properties impaired by leaching are restored by ultrasonic treatment
Inventor: WEBER EKKEHARD PROF DR ING
IPC: C03C25/00
Filed: 1979-06-23
Abstract: The fibres are subjected to an extn. treatment which increases their SiO2 content, but disturbs the molecular structure of the individual fibres and forms cavities due to the leaching process. After the extn. or leaching treatment, the fibres are exposed to ultrasonic energy to restore or repair their molecular structure. The ultrasonic treatment is pref. undertaken at a constant or varying frequency while the fibres are in a dry state or in a bath, esp. in a bath contg. substances such as SiO2 and/or metal cpds. used to fill the cavities and consolidate the fibres. Used on glass -fibres, -mats, -fleece, or -felt.
