Patent DE-2640984-A1 (DE)
Title: Damaged road surface stripping and renovation - involves spreading stripped material in depressions, heating and adding new material
Inventor: WIRTGEN REINHARD
IPC: E01C23/06
Filed: 1976-09-11
Abstract: Removal is carried out only down to part of the depth of the damaged areas. Part of the stripped material is distributed in the depressions and consolidated. The surface is then subjected to heating and roughening, and new material is simultaneously applied. The steerable vehicle used for this has stripping and surface application assemblies. The cutter or stripper (5) is followed by a stripped material distributor (9), consolidator (10) and heater (11), and then the assembly (14) for laying new material.

Title: Electrode cells for ozone prodn. - having compensating induced inductance in parallel, acting in reverse sense to applied voltage
IPC: C01B13/11
Filed: 1976-09-23
Abstract: Oxone is produced by static electric discharges through O2 contg. gas esp. air. This is generated by two electrodes sepd. by a di-electric material between which the gas passed. These are connected to an a.c-supply between which is connected in parallel a compensating inductance. The self-induction of the inductance has a virtually opposite voltage proportionality c.f. the voltage dependant capacity of the ozone tube. The frequency of the AC source should correspond approx. to the natural frequency of the parallel oscillating circuit created by the parallel connection from the reactor tube to the compensating inductance. The latter consists of two coils connected in series with a magnetisable core. During the spark discharge, the current density is in the region of saturated magnetisation. The system gives better compensation for fluid currents caused by inductive circuit and thus better electrical efficiency. Excess voltages are obviated.

Title: Hydraulic feed control for turret drill - has sensor to feed impulse to spool valve for each tool spindle revolution
Inventor: PLATZ WILHELM
IPC: B23Q5/26
Filed: 1976-09-25
Abstract: The drill supplementary pressure fluid feed unit comprises a cylinder and a piston guided floatingly between one fixed and one adjustable stop. This divides the cylinder into two chambers. The piston is fed with pressure fluid from the supply pump via conduits which also connects the two chambers with a pump connected path valve. The working spindle of the drilling machine has a switch arrangement, so that for each complete revolution of the spindle a switch impulse is conveyed to the path valve, causing it to change from one outlet to another. The valve impulse control is formed by a contact-less induction type signal transmitter.

Title: Ferrite ring core with internal air gap - provides high inductance at low loads, and significant inductance at high loads
Inventor: TANACH VALENTIN DIPL ING
IPC: H01F1/34
Filed: 1977-01-15
Abstract: The small chokes, for example as employed in suppressor circuits, is formed to provide a high inductance at low load but a still useful inductance at high loads. The required core conditions can be achieved by making a sintered ferrite ring which has an air gap formed into it during the manufacturing process. The gap is enclosed by a thin ring of ferrite material and takes the form of a flattened bubble across the section of the core. A ring core of this type gives very high permeability at very low currents. A lower but, useful permeability is present when only the core sections round the air gap are saturated, and a low permeability is present when the whole core is saturated.

Title: Surface roughness signal processing circuit - suppresses carrier frequency fed to probe using inverter and adder stages
Inventor: KREIENSEN KURT
IPC: G01B7/00
Filed: 1977-03-01
Abstract: A circuit for use with an electromagnetic measuring probe is supplied with an alternating voltage as it traverses the surface of a workpiece at constant velocity to generate a modulated signal. It has provision for suppressing the carrier frequency. A generator (G) supplies an a.c. to a measuring probe (M) which presents at its output a voltage consisting of a component of the same frequency as the supply and a modulation component which depends on the motion of the measuring probe as it traverses the workpiece. The probe voltage is fed to an adder circuit (S). A further input for the adder is derived from the generator by way of an inverter (I) resulting in the suppression of the carrier frequency in the output.

Title: Heart pacemaker battery saving circuit - has pulse shaper output fed to alternative trigger stages to modify pulse trains
Inventor: BLASER REINHARD DR ING
IPC: A61N1/372
Filed: 1977-03-19
Abstract: The battery operated heart pacemaker has a control circuit which at low potentials permits the use of minimum current within safe limits. The device also has an electrode connected to a preamplifier followed by a trigger stage. Its output is fed to a monostable multivibrator acting as a pulse shaper, forming rectangular pulses of opposite polarity. One set is fed to a second trigger stage which also limits the upper frequency of the trigger pulses. A third trigger stage and multivibrator form an alternative path to modify the pulses and fire an increased battery life. The first path establishes the basic rate of the pulses. The recurrence frequency of the pulses are separated at the end of the life of the battery from normal operating conditions.

Title: Sludge dewatering hose - has fully opening bottom with looped end attached to turnable ring
Inventor: KRAUSE WALTER
IPC: B01D29/27
Filed: 1977-04-16
Abstract: A device for dewatering of sludge, e.g. digested sludge in sewage treatment plant, is a cylindrical hose of porous tissue with an opening ring of the same diameter as the hose. The hose is continued beyond the ring and folded back to a second ring. A rotary displacement of the second relative to the first ring throws folds and closes up the bottom opening. This prevents any impediment to the discharge of the dewatered sludge by any restriction, even if it has dried to an almost solid mass.

Title: Para-xylene and para-methyl toluate oxidn. - in three steps differing w.r.t. air quantity charged, to reduce incomplete oxidn.
Inventor: POKORSKA ZOFIA DIPL ING CHEM
IPC: C07C69/82
Filed: 1977-07-27
Abstract: Dimethyl terephthalate is prepd. by air oxidn. of pure p-xylene and p-Me tolulate, or of a recycled p-toluyl ester fraction, under 4-5 atmos. pref. wt. ratio reagents p-xylene. P-Me toluate is 1:1 to 3:1. Standard, opt. activated oxidn. catalysts are used, e.g. organic CO, Mn, and/or Ni salts. Novelty consists in carrying out oxidn. process in 3 steps, differing from one another by quantity of air changed. Steps take place at (1) 125-150 degrees C. (2) 145-160 degrees C, (3) 155-170 degrees C. Air quantity charged to each step is such that O2 content of waste gases is, by wt., 1-2% from (1), 2-5% from (2) and >=3 (6)% from (3). Oxidn. velocity is accelerated by about 10%. Smaller reactors can be used. With increased air excess in 2nd and 3rd steps, reaction mixt. contains 2-5 wt. % more useful prods., e.g. terephthalic acid, p-toluic acid and mono-Me terephthalate. Losses caused by incomplete oxidn. of intermediates, e.g. aromatic alcohols and aldehydes, are minimised.
