Patent DE-3818953-A1 (DE)
Title: Hose clamp
Inventor: SAUER HEINZ
IPC: F16L33/035
Filed: 1988-06-03
Abstract: In the case of a hose clamp comprising a flexible metal band (1) which exhibits a radially outwardly projecting eyelet (2) which is open radially inwardly in the form of a gap before the hose clamp is braced and is intended for bracing the hose clamp by pressing the eyelet legs (13) together, the gap of the eyelet (2) is spanned by a band portion (5), and the band (1) is provided, in an overlapping region of the band end portions (7, 11), with a securing means (12) which is located on one band end portion (11) and can be brought into engagement with a corresponding securing means (6) on the other band end portion (7). In order to be able to use a comparatively thin metal band (1) and, nevertheless, avoid widening of the eyelet (2) after bracing, the invention ensures that the band portion (5) which spans the eyelet gap is a lug (5) which is formed by an approximately U-shaped incision in the band region which forms the eyelet (2), before said eyelet (2) is bent outwards, extends in a circumferential direction and, once the eyelet legs (13) have been pressed together in order to brace the hose clamp, can be hooked to the band portion (9) which overlaps the lug (5), with the result that the eyelet (2) is secured against widening. <IMAGE>

Patent DE-3832352-A1 (DE)
Title: Device (possibly resembling a ballpoint pen) for erasing written texts (handwritten and typed), drawings, etc.
IPC: B43K29/05
Filed: 1988-09-23
Abstract: Hitherto it has been possible to erase written texts with white ribbon in the typewriter or with a liquid (such as Tippex or many others) which is applied with a brush. The use of a ribbon can still be regarded as within economical limits, even if it is regularly not fully used up. A device, possibly resembling a ballpoint pen, is now to offer the opportunity to apply a correction in a more economical and overwrite-friendly manner, with faster drying and finely graduated correction, not only to manually written and typewritten work but also to drawings and much else besides, in fact everything which is suitable.

Title: Processor for real-time transformation coding of video signals
Inventor: LIEBSCH WOLFRAM DIPL ING
IPC: H04N19/60
Filed: 1988-09-29
Abstract: The "discrete cosine transformation" is advantageously suited to concentrating the picture energy onto a few spectral coefficients. The DCT values of importance to a picture content are coded. For a VLSI implementation, circuit patterns which are as regular as possible and have short connecting paths between the individual processor units are to be developed which also provide for use in HDTV systems with video signal sampling rates of around 80 MHz. The processor for direct two-dimensional DCT contains structurally identical base elements 1.n (n = 00, 01, ..., 31, ..., 63) which are serially arranged in four parallel paths (01, 02, 03, 04), an adder (2.i where i = 1, 2, 3, 4) with partially inverted inputs (2.i.j where j = 1, 2, 3, 4) at the input of each path, which adders are connected in parallel to form groups of four and are in each case connected to one of four parallel input lines (3.k where k = 1, 2, 3, 4) and lead to a memory for image blocks from which blocks of 8.8 pixels each are read out. Real-time video signal transformation also for HDTV systems with sampling rates of about 80 MHz and above, as preprocessing for data reduction. <IMAGE>

Abstract: For the purpose of utilising the exhaust gases occurring in particular in the starting phase of a combustion-heated burner and containing toxic substances, there is provided, between the burner and the exhaust-gas duct of the latter, at least one branch line (4) which serves for returning at least a part of the exhaust gases into the region of the burner. The said branch line (4) can be formed at least partly by cavities in a front wall (5), e.g. of the burner plate, terminating the combustion chamber (1) of the burner, or a front wall, e.g. of the housing door, terminating the housing of the combustion-heated device. The branch line (4) can open into the combustion-air duct, preferably containing a blower (7), of the burner, into the mixing chamber of the burner or into the flame tube (6) of the burner. If applicable, a separate blower (8) which conveys the exhaust-gas component to be utilised and into the air-intake connection piece (9) of which the branch line (4) can likewise open can be arranged in the said branch line (4). The activity of the said blower can be limited to the starting phase of the burner operation in which the proportion of unburnt hydrocarbons in the exhaust gases is higher than in normal operation. <IMAGE>

Patent DE-3915942-A1 (DE)
Inventor: KUEBER KLAUS DIPL ING
IPC: B42D7/00
Filed: 1989-05-16
Abstract: In a method for manufacturing a printing product from a multiplicity of sheets lying one above the other in a rotary printing machine, in which method, to form the printing product in the rotary printing machine, the sheets lying one above the other are folded together once along their transverse centre line, a considerable amount of waste paper is produced due to the prefold or return fold required for opening the printing product out again. To avoid this waste, the multiplicity of sheets of the printing product are joined together at least on one side extending transversely to the delivery direction in the region of the trimming edge prior to delivery by the rotary printing machine, in such a way that the prefold or return fold can be omitted and it is still possible for the printing product to be opened out again.
