Title: Two cylinder reciprocating concrete pump - has linkage lifting swivel pipe as it rotates to reduce wear on end of pipe
Inventor: FENZL FRANZ ING GRAD
IPC: F04B7/00
Filed: 1979-03-08
Abstract: The pump has two parallel cylinders (1, 2). Their open ends are linked by curved outlet pipes (6) to an inlet hopper (16). There is a wear ring (10) at the end of each outlet pipe.

Patent DE-2927240-A1 (DE)
Inventor: KIENER KARL DIPL ING
IPC: C10J3/66
Filed: 1979-07-05
Abstract: Fuel such as bituminous coal, lignite, wood, straw and similar, is carbonized at approximately the atmospheric pressure in a first stage by indirect heating between 300 and 600`C while stirring constantly (1). The hot gases released are mixed with preheated air and partially burnt (27) in a second stage. Simultaneously, they are thermally cracked at temperatures comprised between 850 and 1200`C, and they are passed through a reaction zone (35) comprised of low carbonization coke obtained during the first stage. In a third stage, the coke is subjected to a partial combustion, for example by means of air and steam. The gas mixture being initially at a temperature comprised between 900 and 1200`C is sucked through a reaction zone formed with the low carbonization coke where the gas temperature is reduced due to an endothermal reaction and where the calorific capacity of the gases is simultaneously increased. Those gases and the gases coming from the second stage are conveyed towards heat-exchangers (44 to 46) and to gas scrabbers (61).

Title: Synchronising system for communications - synchronises multiplied periodic signals in faster time using parallel or serial devices
Inventor: ANNECKE KARL HEINZ DIPL ING
IPC: H04B1/707

Title: Wood chipping machine with knife spindle - has hinged stops in lower end of feed shaft, thrust aside by incoming wood
Inventor: SYBERTZ HANS
IPC: B27L11/02
Filed: 1980-07-09
Abstract: The machine has a wood feed shaft, with conveying members forming the shaft walls and delivering wood cut to length from the top to the knife spindle. Sliding or hinged stops (6) are mounted outside the lower end of the shaft (1), and are thrust by springs (8) or gravity into the blocking position, in which they cover the knife spindle (3), at least partly. The incoming wood is thrust against ramp faces (10) on the stops, and so pushes them clear of the shaft. The stops can be of plate material and mounted on a common hinge axis (7). The design ensures that the feed rate is always controlled, even if the shaft is insufficiently filled with wood.

Title: Conference reporting system with pulse modulated TDM signals - uses combiner with multichannel input section and two output sections
Inventor: CERNY JOSEF ING DR
IPC: H04B10/114
Filed: 1980-08-01
Abstract: The multiple channel speech transmission system for reporting purposes at conferences, political meetings etc uses pulse modulation with time multiplex transmission, and light or infrared radiation. The multiple channels (M1, M2 etc) are connected to a combining stage (KZE) where the incoming needle pulses are regenerated and galvanically separated by a set of three lines with two output combiners. The input combining stage has an amplifier to increase the level of each input then a pulse shaper for regenerating the pulses, and a monostable trigger circuit. This forms a driver stage for a transistor connected by a resistance and capacitance in parallel to a light emitting diode which produces flashes, coupled to a photo diode followed by a two stage amplifier (KAE1,2) connected to a Schmitt trigger and an output driver stage.
