Title: Pump water extraction cylinder - has tapering channels to lead fluid to cylinder centre against centrifugal forces
Inventor: LUETTICH GERHARD ING GRAD
IPC: D21F1/60
Filed: 1979-03-02
Abstract: In the construction of a cylinder to extract water from a fibre suspension, for paper making; the cylinder is built up from a number of rings with supporting webs (6) which are interconnected at one end and branch out to overlap each other in the direction of rotation. There are channels (9) between two webs which taper more strongly towards the centre of the cylinder than a channel which is formed between two straight webs. The design accelerates the flow of extracted fluid to the centre of the cylinder, so that the forces on the fluid are greater than the centrifugal forces at the circumference.

Title: Rotary boring head and conical cutters - with tungsten carbide ring forming axial and radial slide bearing surfaces
Inventor: KENNICOTT WILBUR L
IPC: E21B10/24
Filed: 1979-12-24
Abstract: A projection from the base of the journal on which a rotary cutter of a boring head turns, forms also a shoulder zone, so that the circumference of the projection forms a radial slide bearing zone and the shoulder forms an axial slide bearing zone. A ring of material highly resistant to abrasion fits into the inner recess of the rotary cutter which has an outwards directed axial slide bearing zone. This works with the axial bearing zone of the journal. It also has an inwards directed radial slide bearing zone which works with the radial bearing zone of the projection. The rotary cutter is assembled on the journal so that the ring rotates with it and between the outer end of the projection and the bottom of the inner recess of the cutter, there is a cavity. Arrangement provides a rotary conical borer as used for large holes and holes for explosive charges. The heavy wear to which conventional cutters are subjected is reduced by a bearing layout which takes the loading in >1 direction.

Title: Vehicle antiskid brake control - has brake reaction controlled feedback force applied to wheel slave cylinder
Inventor: KOENIG HEINZ-WERNER
IPC: B60T8/32
Filed: 1980-03-19
Abstract: The antiskid brake control with no external control circuit has the brake reaction force added to the brake force, with the reaction force lifted as the wheel tends to lock. This reduces the brake effect and lifts the locking action. The master brake cylinder (1) is linked to the wheel cylinder via a control cylinder (2). The brake reaction force is translated into a hydraulic force by a slave cylinder (3) set between the free ends of the brake shoes with this force added to the control cylinder to reinforce the brake pressure. When the wheel locks the additional force is lifted so that the brake force is vented back to the reservoir (13).

Title: Feedback controlled modulation system for antenna circuit - has pulse generating exciter and amplitude modulator and uses envelope detector to produce feedback signal controlling non-linear amplifier
Inventor: DISHAL MILTON
IPC: G01S1/04
Filed: 1980-09-10
Abstract: The feedback controlled modulation system comprises an extended range, gain controlled detector system in a first feedback loop coupled between the output and input of an amplifier having a non-linear input-output characteristic. A gain controlled reference signal source is coupled to the output of the detector system to provide a difference signal in the first feedback loop. A gain controlling pulse generator is coupled to the source and the detector system to simultaneously control the gain of the source and the gain of the detector system. The circuit controls the shape of the difference signal so as to linearise the non-linear characteristic without loss of loop stability and without causing amplitude distortion on the first feedback loop. The modulation system includes an exciter which provides controllable amplitude, rectangular pulses. An amplitude modulator is in the first feedback loop coupled to the input of the amplifier and output of the exciter responsive to the rectangular pulses and an amplified version of the shaped difference signal.
Patent DE-3041879-A1 (DE)
Title: Load dependent, automatic brake pressure regulator - has control valve mechanically coupled to piston element, exposed at its rear side to brake pressure in rear axle brake circuit
Inventor: ENGFER ORTWIN
IPC: B60T8/30
Filed: 1980-11-06
Abstract: The automatic, load adjustable brake pressure control has a rear braking system regulated independence on load, while the front brakes are unaffected. When loaded, a rocker arm (7) in the regulator housing opens a valve (18, 19) with a delay, as the load increases so that brake pressure build-up reacts to the increasing brake pressure. Should the front brakes fail, pressure is released from the valve chamber (28) above the regulator valve value, thus allowing the valve to open so that the intact rear brakes bring the lorry to a standstill.
