Title: Well ventilated foam mattress with longitudinal flexibility - has foam tubes placed cross-wise down between foam mats with ventilation ducts inbetween
Inventor: BRECKLE FRIEDRICH
IPC: A47C27/15
Filed: 1977-01-18
Abstract: The mattress comprises a foam core consisting of two or more foam mats (10, 11) which cover each side of an intermediate layer of foam bodies (12) which are placed crosswise side by side and have a round cross-section. In the transverse direction of the mattress this foam core acts like an integral foamed plastics block but in the longitudinal direction the round foam bodies provide a considerably improved flexibility and produce cavities which ensure adequate ventilation of the foam core. This ventilation is thus achieved by the ventilation ducts (13, 14) which are formed crosswise between the foam mat and the foam bodies. The foam bodies pref. have common dias. and are placed loosely between the foam mats so that although adapting to the movements of the body for greater comfort they also return to their original position.

Title: Shop display and storage shelf with partitions - has perforated rail and flap with different hole pitching allowing infinite adjustment
Inventor: TIREL FRANZ
IPC: A47B96/14
Filed: 1977-02-16
Abstract: The shop display and storage shelves have brackets (2) suspended from verticals holding at least one beam (3) with partitions (4) attached, to form compartments. These partitions have positioning arms (12) with at least one perforated flap (13) which interacts with an associated perforated rail (9). They both have rows of holes (10, 14) of the same height but different pitch, the pitch of the holes of the rail (9) being preferably greater than that of the flap (13) preferably in the ratio 4 to 3. The flap and the rail can be fitted together by at least one push-in lock and by using the different spacings of the holes it is no longer necessary for the minimum partition displacement to correspond to the division of the holes, but rather an infinite adjustment is possible. This ensures that the shelf compartments can be matched to the required goods with minimum tolerance allowance whilst the shelving itself is very stable.

Title: Turf consolidating perforated concrete block - has unequal number of teeth and gaps on opposite side facilitating curves
Inventor: CLAUSSEN LORENZ DIPL ING
IPC: E01C9/00
Filed: 1977-09-27
Abstract: The shaped concrete has one or more apertures (2) passing through it from base to top, and is pref. used for enabling vehicles to pass over turf areas or to secure embankments. Two opposite sides (A, B) at least, are formed with serrations and gaps (3 - 10, 11 - 14), the number of these being different on the two opposite sides. One side may begin with a gap and end with a tooth, and the opposite side vice-versa, while one side's teeth may be all of the same length and shorter than its gaps. This permits constant interval between blocks, and at the same time permits them to be laid in curves without leaving wedges larger than the perforations.

Title: Quantitative determn. of protein in antigen sample - by immuno-electrophoresis and immunodiffusion
Inventor: ALADJEM FREDERICK J PROF
IPC: G01N21/86
Filed: 1978-04-25
Abstract: Concn. of a protein in an antigen sample is quantitatively measured by immunoelectrophoresis. This includes selective protein migration by electrophoresis in one dimension in a thin layer of supporting medium. The antigen is then subjected to immunodiffusion with an antibody source contg. an antibody specific to the protein. The protein and antibody diffuse into reactive contact in another dimension through an area of the medium layer initially free from antigen and antibody, and they react to form an elongated pptn. zone. The zone is scaned optically under dark field illumination at a selected time after the diffusion starts. There are parallel, spaced scan paths that cross the zone transversely to develop electrical intensity signals (the intensity of scattered light at posns. on the path, partly in the zone and partly out). From the signals an electrical sum signal for the sum of the effective excess of each intensity within the zone over intensities outside the zone. This signal is compared with reference signals produced with controls in a similar procedure. The process facilitate distinction among pptes. formed by different proteins; so that quantitative and reliable results are obtd. Rapid, reliable and economic process is used for the analysis of serum, spinal fluid, tissue extracts etc. used in clinical diagnosis.

Patent DE-2820920-A1 (DE)
Inventor: HUONDER ANTON
IPC: E04B1/80
Filed: 1978-05-12
Abstract: Each of the two metal members of each anchor comprises at least one bracket (5, 7) and the bracket tops (5a, 7a), engaging one over the other, fully enclose, from opposite sides, the insulating intermediate piece (8) which is adapted to the shape of the tops of the brackets. Each anchor is symmetrical in terms of its longitudinal central plane perpendicular to the panel plane. Its brackets comprise rounds or flats. The intermediate piece (8) expediently has a polygonal cross-section. The bracket arms run apart from one another at an angle of 45 DEG , from the top to the concrete layer. In order to render the panel self-supporting throughout, one anchor is arranged in each quarter of the panel surface, such that the longitudinal central planes (a) of two neighbouring anchors are inclined, towards opposite sides, at an angle of 45 DEG  to the panel edge. It is particularly advantageous to effect the arrangement such that the 90 DEG  angle between the longitudinal central planes of neighbouring anchors opens towards the panel centre. By means of this anchor design and arrangement, the composite panel is rendered self-supporting throughout and is particularly suitable for walls of multi-storey chilling blocks. <IMAGE>

Title: Laundry folding mechanism - has conveyors with folders at transfer points to give a compact layout
Inventor: SCHUSTER WOLFGANG
IPC: B65H45/04
Filed: 1978-05-26
Abstract: In the equipment to fold laundry items a number of times, there is an initial conveyor belt to carry them at an angle of 30 degrees, and a second conveyor belt at the rear of the first conveyor so that the laundry is caught and clamped between the reverse level of the first conveyor and the forward level of the second conveyor. There is a third, approximately horizontal, conveyor which moves against the direction of travel of the second conveyor. There is an insertion folder at the transfer from the first to the second conveyor and also at the transfer point between the second and third conveyor. This folds the laundry along a line running across the advance direction of the conveyors. A fourth conveyor extends the line of the third conveyor, moving in the same direction with a controlled drive. There is an insertion folder in the plane of the fourth conveyor, folding the laundry along a line parallel to the direction of conveyor travel. The design gives a compact folding unit, without requiring folding rollers.
