Patent DE-3908341-A1 (DE)
Title: Means for protecting children's heads from being flung forwards in child car seats
Inventor: HUESGEN HARALD F
IPC: B60N2/28
Filed: 1989-03-15
Abstract: In child car seats of the prior art, the child's head is not secured in the event of accidents. Due to the fact that the child's body is held fixedly in the seat, the head, which is heavier in childhood than when grown-up, is flung violently forwards. Time and again this results in the most severe paraplegia in children who are subsequently paralysed for their whole life from the neck downwards and are unable to breathe. These injuries could be avoided by a restraining device for the child's head. The applicant (himself an emergency doctor) is therefore applying for his proposal, for the protection of the child's cervical spine, to become a patent, as a means for protecting the child's head from being flung forwards in child seats: By virtue of a restraining device, which can be a strap, a padded bar etc., placed in front of the child's forehead, in an accident the child's head is unable to fly forwards and tear the spinal cord (medulla). This restraining device, swung down after the child has been seated in the child seat, is described and claimed in the enclosed patent.

Patent DE-3921901-A1 (DE)
Title: Transcoder
Inventor: PLANTHOLT MARTIN DR ING
IPC: H04N7/01
Filed: 1989-07-04
Abstract: To improve the image reproduction of an image signal, an increase of the current standardised line number to twice the number but retaining the line interlace method has been proposed. The disadvantages known from the line interlace method are not eliminated by doubling the number of lines. In a first intermediate step, the image signal of the first standard with line interlace is converted into an image signal of a third standard without line interlace. In a second intermediate step, the image signal of the third standard is converted into the image signal of the second standard with twice the frame repetition rate of the image signal of the first standard. The invention is used in image reproduction devices.

Title: HF igniter with loss compensation for discharge lamp - occupies min. space with components laid out according to criteria of size instead of energy loss
Inventor: BLATTL STEFAN
IPC: H05B41/04
Filed: 1989-12-21
Abstract: The smallest available ignition transformer (Tr1), capacitor (C), spark gap and Tesla coil (Tr2) are used irrespective of losses encountered in the energy balance, which are compensated by increased capacitance. The ignition transformer may be protected from the higher voltages arising during the ignition phase by rearrangement of the spark gap in parallel with its sec. winding, and the capacitor in series with the tap of the Tesla coil. ADVANTAGE - No separate ignitor housing is required, thermal degradation of operational reliability is avoided, and lamp can be held and operated by one hand. (5pp Dwg.No.1/2) (Printed in week 9128)

Title: Prodn. of colour printed mouldings - by thermo-forming polycarbonate film which is silk screen printed and adhesive coated on underside before bonding it to moulded base
Inventor: DOERKEN MICHAEL
IPC: B29C70/78
Filed: 1990-05-11
Abstract: Mouldings are produced with a base and a cover film which is bonded to it and has a relief pattern produced formed under pressure and (if necessary) heat. This cover film is preformed first with its relief pattern and is only moulded to shape when the base is being formed. Pref. cover film is made of polycarbonate, and the base is pref. thermoplastic. The product consists of a plastic base (1) and e.g. transparent polycarbonate cover film (2) with a number of inkings (3/4) silk screen printed on to the film (2) underside. Parts of the printing are removed to produce transparent areas; some of these areas are covered with a different colour to produce the specific markings (5) (e.g. symbols, etc.). This printed side of the film (2) is also coated with a heat-activated adhesive (6). This film (2), moreover, is preformed (7a) with a suitable pattern at appropriate thermo-forming temp.. The forming tools used have a highly polished finish. The moulded film (2) is then placed in a suitable injection mould where the base (1) is produced and, at the same time, the adhesive (6) is activated so as to bond film to base. It is also possible to produce the relief pattern in the injection mould. ADVANTAGE - The products are free from unsightly surface faults even if the cover film has to undergo a relatively large degree of change of shape.
