Title: Automatic safety belt for aircraft and road vehicles - has stop or guide eyelet to hold belt slightly away from body
Inventor: HERRMANN HEINRICH
IPC: B60R22/19
Filed: 1975-05-26
Abstract: Automatic safety belt for aircraft and road vehicles comprises a winder of which the spring traction force applied to the belt can be stopped immediately before the belt comes to rest on the body of the occupant by means of a stop or other suitable device on a guide eyelet on the belt or on the winder housing. When the belt is not being used, the stop can rendered inoperative, so that unobstructed winding of the belt is possible. This prevents a feeling of confinement on the part of the occupant, which can become extremely annoying on long journeys.

Title: Reaction vessel for extractive phosphoric acid prodn. - agitator shaft spray nozzles mix liquor more quickly and intensively (CS270276)
Inventor: BRJUNOW WLADIMIR ILITSCH
IPC: B01J19/18
Filed: 1975-05-28
Abstract: A reactor for the extraction of phosphoric acid from phosphate rock has a cylindrical vessel with a cover, and mechanical agitator enclosed by a diffuser, a number of auxiliary agitators with vertical driving shafts, a device for loading the rock into the diffuser, and means of feeding in the sulphuric acid and recycled phosphoric acid, as well as of drawing off the reaction liquor and venting gases produced. Each of the auxiliary agitators has a cylindrical conical nozzle with its outlet pointing downwards and its lower end so positioned on the driving shaft that it is below the level of the reactin liquor in the vessel. It serves thus to pick the fluid up and scatter it in an umbrella shape, below the level of which air inlet pipes reach down from the cover. The reactor has ample capacity for vaporising the mass of liquor preventing overheating and increasing productive capacity. Raw phosphates containing carbonates of the metallic alkaline earths, the processing of which normally sets up large amounts of foam, can be handled without reduction of output.

Title: Steerable childs boat shaped sleigh - is actuated by tilting for contacting control strips with snow
Inventor: APPEL WOLFGANG
IPC: B62B15/00
Filed: 1975-07-17
Abstract: The steerable sleigh has a boat shape and can be used on firm or loose snow, being readily steered by children with no projecting features which could be torn off. The steering and braking strips are firmly attached on the outside wall as longitudinal and transverse strips or plates. This strips are brought into contact with the snow to a required degree by tilting the sleigh. The tilting is carried out by the displacement of the body weight of the person within the sleigh. The steering profiles will come one after the other into contact with the snow when the sleigh is tilted. These strips are curved and they have different radii. The strips contact the snow when the sleigh is tilted backwards. The strips have teeth to prevent accumulation of snow.

Title: Cancer cell irradiating system - uses blue or ultraviolet radiation combined with ultrasonic or hypersonic oscillations to disrupt cells
Inventor: HANSCHMANN HORST
IPC: A61G10/00
Filed: 1975-07-28
Abstract: Blue light or solar radiation, i.e. a blue or long ultraviolet wave length radiation, source is used to break down nucleic acid chains with molecular flaws in the chain in the nuclei of the cancer cells or to damage viruses in the cancer cell. Antigens are produced to prevent formation of these flawed nucleic acid chains thus preventing production of cancer-modified DNA cells. Pref. initially, a large proportion of the cancer cells are broken down by ultrasonic or hypersonic waves steered in small oscillations using concave mirrors arranged in a ring. To aid formation of antigens cancer cells present can be rubbed into the skin then irradiated. X-ray equipment and a fluorescent screen can be used in conjunction with the ultrasonic equipment.

Title: Degassing of coagulation sensitive polymer dispersions - using a high frequency field to heat the polymer
Inventor: NETTESHEIM GOTTFRIED DIPL CHEM
IPC: C08F6/16
Filed: 1976-04-05
Abstract: Procedure for the degassing of coagulation sensitive VC monomer contg. PVC, or VC copolymer dispersions with is not 50 wt.% VC, by the effect of reduced pressure with simultaneous warming. Pref. pressure range is between the water vapour pressure at the temp. of warming and a pressures 0.2 bar higher. The VC monomer content is reduced to 500 ppm before further processing. The polymer latex, after the polymerisation is finished, is warmed to 60-90 degrees C, pref. 75-85 degrees C, in a high frequency field of 3-10000, pref. 3-3000 MHz. Coagulation sensitive PVC contg. polymer dispersions can be heated in a high frequency field, without coagulation, to a temp. sufficiently high to allow the VC content to be reduced to 500 ppm by vacuum degassing. In an example, 1 l of coagulation sensitive PVC latex in a flask, with a residual monomer content of 2000 ppm. was heated from 40 to 80 degrees C using a high frequency field of 2450 MHz of l00 watts power, in 4 minutes. There was negligible coagulation. After degassing for 1 1/4 hours with slow stirring at 450 Torr absolute, the prod. had a content of 480 ppm VC monomer.
