Title: Finishing pelts by coating leather and pile - with thin vacuum-deposited metal, metal alloy, semiconductor and insulating layers
IPC: D06P3/30
Filed: 1977-07-28
Abstract: Animal pelts are finished by coating with pigment layers applied as one or more vacuum-deposited opt. superimposed thin films. On finishing the hair-side of pelts, coating thickness seen from hair tip is varied by applying an electric potential to pelts and/or by varying the vacuum pressure and/or by varying the angle of incidence of the impinging coating material stream to main hair axis. One or more substances can be applied with different angles of incidence to main hair axis. The thin films can also be applied to leather side of pelt. One or more of the thin films are metal-, metal alloy- or semi-conductor films. Thin insulator film(s) can also be applied, esp. as cover layer. New optical effects and optimum protection against weathering and ageing can be achieved without altering hand and structure of pelt. Hair anchoring in leather is unaffected. The thin films are flexible and do not impair pelt and leather softness.

The bag is then turned from a horizontal to a vertical position by a second conveyor having a guide rail (24) shaped like a roof, the sacks being moved by friction rollers (26) and brought underneath the fitting connection.
Patent DE-2737530-A1 (DE)
Title: Channel filter for FM communications signal - has transfer characteristic which minimises differential gain and phase spreads for given out of band attenuation
Inventor: MUENZEL FRIEDRICH DIPL ING
IPC: H03H7/01
Filed: 1977-08-19
Abstract: The channel filter, for FM or angle-modulated communications signals in which the baseband signal includes one or more subcarriers, has a steeper rise in attenuation for constant distortion or fewer circuit components for the same rise in attenuation. The filter's transfer function is chosen so that the spread of the differential gain and/or the differential phase at a given attenuation outside the band is a minimum. The filter is thereby optimised directly for minimum differential distortion in the video band and can consequently be used for higher quality tv transmission without having to increase the number of components.

Title: Fluidised treatment of suspended particles with many fluid inlets - capped by cowls to prevent flow back of particles
Inventor: MORGAN JOHN HILEY
IPC: B01J8/18
Filed: 1978-01-10
Abstract: A method of treating fine particles of materials is carried out in a treatment zone, through which a pressurised fluid flows in a pattern distributed across the zone in order to keep the fine particles constantly in movement. The pressurised fluid enters the zone through a large number of openings, each of which is surmounted by a kind of shield to prevent the fine material from passing back through the opening. In a variant, coarse particles are allowed to collect adjacent to the zone, or scatter-promoting devices are incorporated into the path of the fluid to break up its flow. Used for any kind of treatment of particles involving a fluid, esp. gas, e.g. for heating, cooling, humidifying or drying materials e.g. sand, gypsum, or cement. Typically, the cooling of hot sand for use in metal casting.
