Title: Hop drying kiln spreader - with pantograph linkage and tension spring for rollers on revolving spider
Inventor: EBERL MARTIN
IPC: C12C3/02
Filed: 1976-03-12
Abstract: The parent patent described a hop drying kiln spreading attachment consists of a motor driven spider with radial carrier arms for raking blades and hinged links with rollers. Springs urge the rollers against a track on the inside kiln walls. In this addn. a pantograph linkage is fitted between the spider and the hinged carrier arm. A tension spring between two linkage hinges urges the roller against its track. This overcomes the difficulty to achieve an adequate contact force between roller and inside kiln wall in large hop drying kilns.

Title: Continuous drying and/or granulation of bulk materials e.g. pastes - in cylindrical drum in which the material is moved countercurrent to a flow of drying air
Inventor: LIPP EBERHARD
IPC: F26B17/20
Filed: 1977-07-08
Abstract: A cylindrical fixed drum mounted horizontally has at one end, inlets for the bulk material and for drying air and, at the other end, outlets for the dried material and for the moist air. A shaft is mounted along the axis of the cylinder, driven by a motor, to which radial arms are attached. The arms carry at thier ends plough shaes which impart a small velocity component to the material in the direction opposed to the direction of the stream of drying air. Specifically rotating blades mounted on shafts at the bottom of the cylinder and perpendicular to the cylinder wall prevent the material from coagulating into hard lumps. An impact wall at the after end of the cylinder before the section contg. the two outlets prevents the carry-over of material in the airstream. A central hole in this wall allows the granular material to flow out into the discharge and also determines the height of the material in the cylinder. Bulk material with a moisture content of 80% can be dried to a moisture content of 18%.

Title: Automatic triple pressure brake system for railway vehicle - has main pressure distributor with differential piston to accelerate first braking stage
Inventor: PRADA CESARE
IPC: B60T15/42
Filed: 1977-07-11
Abstract: The main pressure distributor consists of two pistons to connect the brake cylinder with the auxiliary air container and progressively vent the brake cylinder. One piston defines two chambers, one communicating with the auxiliary container and the main feed pipe via a calibrated bore and a non-return valve. The second chamber has an accelerator valve which is joined to the venting valve and the check valve. The valves are controlled by the first braking stage and the brake cylinder supply. The second piston is a differential piston to cause the closing pressure for the first braking stage. Towards the end of the braking process, the valve is re-opened for the first braking stage. At the same time, the venting and check valves are re-opened at a pressure value considerably less than that of the return to normal working.
