Title: Silk underwear fabric - is mfd. using separate strands of wild and cultivated silk to reduce costs
Inventor: FOERSCHLER KURT
IPC: D03D15/00
Filed: 1976-05-10
Abstract: In the mfr. of silk fabric, partic. for undergarments lying against the skin, the material is formed from a mixt of cultivated and wild silk. The fabric gives the maximum physiological properties of silk, but with reduced material costs. The silk to be used is suitably harvested from silkworm of the types: Chinese Oak (Antheraera pernyi), Japanese Yamamay (Antheraera yamamay), Indian Moonga (Antheraera assama), and partic. Indian Tussah (Antheraera mylitta). The fabric is composed of equal parts of cultivated and wild silk, the two types being used separately for the warp/weft and the silk threads are not twisted together. The individual silk threads are aligned in parallel to build up silk strands with a dia. of 0.1-1.0 mm. The material can be developed by working together two overlapping layers of fabric.

Title: Hydrogen sulphide removal from gas on active charcoal - in presence of oxygen, preventing sulphur oxide formation
Inventor: HENNING KLAUS-DIRK ING GRAD
IPC: B01D53/52
Filed: 1976-11-16
Abstract: In the sepn. of H sulphide from gas mixts. in the presence of oxygen or active C at elevated temp. to form S, the H sulphide-oxygen molar ratio is 1:0.55-0.65, pref. 1:0.575 and the pressure 1-50 bar.

Title: Display method for dangerous movements of objects - is for marine or coastal navigation and employs rectangular coordinate display of radar echoes
Inventor: HINSCH WERNER
IPC: G01S7/22
Filed: 1976-11-23
Abstract: The method uses radar direction finding or surveillance radar. Echoes received by the radar are displayed, in accordance with their direction and distance in rectangular coordinates on a picture screen of an additional display unit. Their lateral distances from the origin corresponds to the bearing, and vertical distance from a horizontal line to the distance. Echo signals are modified so that their vertical length is a measure for the object rate of approach. The system enables compass bearings to be deduced in such a way as to avoid a possible collision with the object revealed by the survey.

Patent DE-2656514-A1 (DE)
Inventor: HECKHAUSEN HERRMANN J ING GRAD
IPC: G21D1/02
Filed: 1976-12-14
Abstract: To avoid damage to structural members which run in the vicinity of pipelines, the same are surrounded by pipeline safety devices anchored in concrete walls (3, 4). So that the enormous forces are not passed directly into the concrete walls when the pipeline safety devices respond, the safety devices consist of individual plastically deformable girders (6, 7, 8, 9) subject to bending. The girders subject to bending are connected to the concrete walls with bearings (5, 5a) in between. The gap between insulation (2) and girders subject to bending is kept as small as possible in order to keep down the kinetic energy from pipe-fracture parts in the event of any pipe fracture. <IMAGE>

Title: Large surface heat exchanger panels prodn. for space heating - using two dimpled rolled metal or plastics sheets seam welded at edges and spot welded in dimples
Inventor: SCHIMMELPFENNIG KLAUS DIPL ING
IPC: B21D53/04
Filed: 1977-06-16
Abstract: Large surface area heat exchangers are produced from two sheets of rigid material of approx. the same width.

Title: Automatic splicer for broken ends on winding frame - transfers threads from above and below into pneumatic chamber
Inventor: ROHNER JOACHIM
IPC: B65H69/06
Filed: 1978-03-13
Abstract: A mechanism including a chamber having a lengthways running groove, which can be covered by a hinged cover, and into which two ends of yarn can be introduced and spliced by means of a lateral jet or compressed air, serves to join a thread from above to a thread from below. The introduction of the broken ends of the thread into the longitudinal groove is effected by a mobile device for drawing the thread which is displaced from a position in which it locates and picks up the thread to one in which it releases it. The threads are introduced into the chamber either, not crossed, and pref. parallel to each other, and are held until the compressed air is delivered, or they may be crossed during the pivoting action of the thread drawing device. The chamber is closed by a cover. The ends of the thread from above and of the thread from below are automatically sheared. Compressed air is blown into the chamber. Used to effect a joint by a splice between an upper and a lower end of yarn, as in a winding frame, whilst eliminating all the influences which depreciate the quality of the joint and depend upon manual skill.

Title: Appts. for washing gas stream containing suspended solids - having rotor on base plate with ring of flights to impart centrifugal motion with outer perforated cylinder to break up droplets
Inventor: BOEHRINGER PAUL
IPC: B01D47/16
Filed: 1978-04-17
Abstract: Wet cleaning of gas streams containing solids uses scrubber with inlet for the dirty gas with inlet branch on this for the wash liquor. This enters the centre of a rotating drum. The drum has a ring of flights to impart radial motion to the gas. Around the flights is a cylinder with perforations in it. The gas/liquid mixtures enters the centre and is thrown outwards by the rotor. The liquid/solids mixture which forms is knocked out by an impingement type separator and the resulting slurry drained off. For cleaning dirty gas streams. Gives a maximum active surface with forced acceleration of the gas stream so the washing effect is not dependant on an externally generated velocity in the gas stream.
