[Also in Division B5] An open-structured semi-permeable membrane is obtained by dissolving a neutral, non- cross-linked polymeric binder and an inorganic salt in a common solvent, forming a thin film from the solution, heat and pressure curing the film and lixiviating with a solvent in which only the inorganic salt is soluble so as to remove at least a portion of the salt and impart a desired degree of semi-permeability to the membrane. The inorganic salt may be potassium iodide, sodium iodide, potassium bromide, sodium bromide, potassium thiocyanate, sodium thiocyanate, ammonium bromide, ammonium nitrate, lithium chloride, zinc chloride or anhydrous ferric chloride. It may constitute up to 80% by weight of the binder. The membrane may be removed from the substrate on which the film is formed if so desired. Suitable substrates are woven or non- woven fabrics of wool, polyesters, nylon, cotton, regenerated cellulose, acrylics, polypropylene, isotactic polyethylene, and polyfluorinated hydrocarbons. Numerous suitable solvents are specified. An ion exchange resin such as melamine-guanidine formaldehyde, urea-guanidine formaldehyde, aminated chloroalkylated copolymers of monovinyl and divinyl aromatic hydrocarbons, phenol sulphonic acid-formaldehyde resins, polystyrene treated with mineral acid or carboxylic acid may be present. Suitable binders are polyvinylidene fluoride, vinyl chloride-vinyl acetate copolymers and polyvinylidene chloride.

Title: Belt pocket forming process
Inventor: ZUR DIPL-KFM NEDDEN CLAUS
IPC: B29C44/32
Filed: 1970-04-25
Abstract: Mould closed on five sides is adhered to a pre-roughened and degreased area of a conveyor belt and injected with polyurethane foam. This sets and the mould is then allowed to cool and is withdrawn, leaving formed pockets, shoulders or rims on the belt, serving as carriers for the material. The formed pocket is then roughened and degreased to apply the next pocket or rim section in a continuous process. The sides of the mould are carried on bolts for downwards guidance and can be removed after moulding to ease withdrawal. The mould is raised and lowered by piston and cylinder using rods to link these to the mould baseplates. Cheap, light in weight, tough, durable, resistant to temperature and rough handling.

Title: Relative velocity measuring system for ocean currents - ensures that the echo signal is always above the noise level
Inventor: GRAEFE VOLKER DIPL PHYS DR
IPC: G01S15/58
Filed: 1973-09-15
Abstract: Sonic signals are reflected by the water back to the signal generator together with a Doppler component representing the relative velocity. The echo signal with the superimposed Doppler frequency is fed to a threshold circuit which transmits the echo signal to a Doppler analyser if its amplitude lies between upper and lower threshold values. A signal transmission gate between the sonic signal generator and a transmission frequency oscillator is opened and closed by a clock signal generator in synchronism with the closing and opening of a receiving gate, whereby the clock signal generator receives a start signal from the threshold circuit whenever the echo signal is below the lower threshold value.
