Patent DE-2107775-A1 (DE)
Title: Briquette prodn from lignite - for metallurgical coke mfr,by fine grinding before compression
IPC: C10L5/04
Filed: 1971-02-18
Abstract: The crude lignite with water content of 50-60% is first crushed or pulverised, and then given a fine grind to release the bound water. It is immediately compressed into briquettes, dried and coked. Lignite with higher water contents is dried before comminution while water is added to lignites with lower water contents. The briquettes produce coke of strength and density suitable for smelting processes esp. of iron ore, with lower sulphur and phosphorus contents than coke made from coal.

Title: Ski binding for downhill and cross country - torsion controlled heel catch and front hinged sole plate
Inventor: WECKEISER KURT A
IPC: A63C9/08
Filed: 1973-07-21
Abstract: The step-in type of safety binding has a spring controlled heel retainer which together with a toe clamp holds the boot to the ski until displacing forces exceed the preset limit. The boot support is held to the heel by a further latch. The heel retainer can be opened to release the sole support so that the whole boot can rotate about a transverse horizontal axis in front of the toe cap while being retained on the sole support by the spring controlled bindings. This arrangement allows the binding to be used for normal downhill use as well as for long distance touring where the heel is required to be free to lift.
Patent DE-2339561-A1 (DE)
Title: Ice cream deep freeze tunnel - has supporting rods on endless conveyor links for container stacks
Inventor: BREUNING ERNST DR-ING
IPC: F25D13/06
Filed: 1973-08-04
Abstract: A continuous deep-freeze tunnel for ice cream packed in cones or containers includes an endles conveyor with supporting rods on its links. The ice cream packs are stacked in containers which have elongated holes on two opposite sides. The containers are supported at the lee-side by the rods as cool air is blown across the tunnel in a direction at right angles to the conveyor motion. Thus there is no danger of the stacks being shifted or tippled by the cool air blast. The capacity of a tunnel can be increased by using higher stacks.

Title: Bearing housing for agitator shaft - being so arranged that bearing and seal can be removed with lifting drive
Inventor: BRUNNER MARCEL
IPC: B01F15/00
Filed: 1973-12-19
Abstract: Housing for the bearing and seal on an agitator shaft in stirring vessel consists of a wall mounted on a pad on the vessel. The drive shaft is connected by a rigid coupling to the agitator shaft. The agitator is mounted in a bearing and, the shaft is sealed. There is a space between the end of the two shafts so that the coupling, the bearing and the seal can all be removed via an opening in the housing. In order to remove the bearing and seal, a lifting device with threaded drawing rods and lifting pts. can be inserted. The system allows the bearing to be serviced and the seal to be replaced without complete removal of the drive motor.

Title: DC motor brush assembly commutator segments - are arranged to drive battery for intermittent motor longer supply only
Inventor: REGEHR ERHARD
IPC: H02K25/00
Filed: 1974-01-10
Abstract: The brush assembly, for a d.c. motor, has its mutually-insulated commutator segments arranged so that for specified period of the motor cycle the drive battery is disconnected from the windings. Periodically disconnecting the battery in this way increases its lifetime when the motor is running continuously. Commutator segments opposite each pair of brushes are arranged so that e.g. one half revolution the brushes do not supply the windings and for the other half they do. The same principle can be applied to a self-exciting generator brush system.

Title: Electromagnetic drive for toy level-crossing gate - has one-piece carrier for pivot arm and rocker and guiding coupling plunger
Inventor: ROETHER HELMUT
IPC: A63H19/34
Filed: 1974-02-06
Abstract: Electromagnetic drive for a track toy article has a pivot arm and a rocker which displaces it; a one-piece carrier for the pivot arm and rocker; and a plunger guided in the carrier as a coupling element for the arm and rocker. The rocker forms an armature for a free end of a sheet metal magnet core, so that the double-armed level-crossing beam is opened by gravity. Preferably the plunger is a needle and a coaxial cam on one arm of the sheet-metal rocker; the needle is guided by the pedestal of the carrier. The electromagnetic circuit is broken with the beam open, and only 2 control elements (rocker and plunger) are required.

Title: Length measurement of continuously cast billets - measuring roll lowered onto billet by proximity switches in tuned circuits
Inventor: LOTZ HORST K
IPC: G01B7/04
Filed: 1974-03-07
Abstract: A length measuring unit, esp. for continuously-cast metal billets, using a measuring roll rotated by the travelling billet, and with a device, operated by a controller, for moving the measuring roll onto the billet and then retracting it when the measurement is complete. The controller is fitted with a probe located on the same side of the billet as the measuring roll, both the probe and the roll being aligned perpendicular to the billet. The controller pref. uses one or more inductive or capacatie proximity switches in electronic circuits fed with adjustable theshold values so that the measuring rolls is lowered exactly onto the front edge of the billet and raised immediately the tail end of the billet is reached. This unit is more accurate and more reliable than conventional devices, being virtually unaffected by dirt; it may also be used for contact-less measurements.
Patent DE-2412091-A1 (DE)
Title: Electro-erosion machine wiyh controlled current discharge - using sequential transistors for current pulses with inclined wavefront
Inventor: SAITO NAGAO
IPC: B23H1/02
Filed: 1974-03-13
Abstract: In an electro-erosion machining process controlled discharge current pulses are applied intermittently to the working gap between electrode and workpiece by an assembly of semiconductor devices. The current pulses differ from the conventional square pulses by having an inclined wavefront. The inclined wavefront is produced by successive switching of the semiconductor devices in a programmed sequence and in certain intervals. The rise time of the discharge current pulse is adjusted to 0.5-1.0 mu per A depending on the peak value of the current pulse. This reduces the electrode consumption to a min. and ensures a stable operation without making excessive demands on the skill and experience of the operator.

Title: Gas washer for dust removal - with repeated warming and cooling to pass stream through dew pt.
Inventor: HOELTER HEINZ
IPC: B01D47/10
Filed: 1974-07-23
Abstract: The performance of gas scrubbers is improved by causing the gas stream to drop below its dew pt., preferably to do this several times. This repeated action is achieved by alternate heating and cooling the gas stream. This in turn is achieved by passing the stream being heated and cooled in counterflow to the involving warm gas stream before it reaches it dew pt. The system can be boosted by using a compressor which has the dual purpose of pulling the gas through the system on its suction side, raizing the temp. above the dew pt. and then subsequently passing it into a water spray for further cooling and washing. The efficiency of wet dust removal systems or washers is improved by dropping the gas temp. below the dew pt. In most washers this is done once at the washing stage. However, the overall separation and degree of agglomeration is much improved if the gas is repeatedly caused to drop below its dew pt. with intermediate heating.

Title: Control circuit for variable - maintains effective valve constant with respect to nominal value
Inventor: WATERMANN GREGOR ING GRAD
IPC: G05F1/455
Filed: 1974-09-30
Abstract: The nominal effective value is represented by a d.c. voltage, and the control is carried out by a thyristor a.c. regulating unit, whose phase shift is controlled by a comparator for nominal and actual values. The variable (UL1) is measured by a series circuit consisting of a resistor (r15), a rectifier diode (D12) and a capacitor (C1) shunted by a resistor (r17). A shunting circuit with a variable resistor (r16) branches off at the junction point between resistor (r15) and diode (D12), and a voltage (Uc1) representing the effective value of the variable, rectified and smoothed, is collected from the capacitor (C1) and applied to the comparator's (V1) actual value input.
