Patent DE-2639899-A1 (DE)
Title: High-quality lump coke from non-coking coal - by briquetting under high pressure and coking without oxidative preheating
Inventor: KRUG HERBERT PROF DR ING
IPC: C10B57/00
Filed: 1976-09-04
Abstract: Prodn. of high=grade lump coke from non-coking or low-coking coal involves crushing to fineness of 1/0 mm., homogeneous mixing with binder pref. in amt. of 7.5-12% briquetting under high press. of 600, pref. 1000 kp/cm2 min. at a temp. dependent on the binder, and coking with rapid heating, pref. at 30 degrees K/min., without previous thermal oxidn. The binder may be pitch, but also suitable are high boiling and asphalt-rich tar and oil-processing products which cannot be used for normal briquetting and coking. Organic waste prods., esp. scrap rubber, may be mixed with the binder to improve its properties. Stability of the briquettes is improved and volatilisation of the binder during heating-up reduced, so that odixative pre-heating of the briquettes is eliminated. Costs are reduced and economic use made of water materials, e.g. scrap tyres. which can be emulsified in the binder, e.g. coal tar, in ratio 1:3-10.

Title: Circular or polygonal shaped electroplating drum - where the periphery consists of a row of bars sepd. by spacers to form drainage gaps
Inventor: STONNER ERWIN
IPC: C25D17/20
Filed: 1976-09-29
Abstract: Electroplating drum with a round or polygonal shape, the jacket of which is assembled from individual, non-conducting elements, has the elements consisting of an axial configuration of round bars or tubes located in slots in the two end walls of the drum and locked in position by end plates on each wall, the width of the gaps between the individual bars or tubes being determined by distance webs. The tubes pref. consist of metal coated with plastic, whereas the bars are pref. made of plastic, the location of the bars or tubes determining the profile of the drum. The gaps between the bars or tubes are easily adjusted to suit the size of the work being barrel plated; the amt. of soln. carrier over into the next tank is reduced as compared with conventional perforated drums, and the voltage drop through the drum periphery is less.
Patent DE-2647216-A1 (DE)
Title: Heating unit for buildings or swimming pools - has heat pump, and additional boiler operated when temp. falls
Inventor: HOLLAND HERMANN
IPC: F24D3/18
Filed: 1976-10-15
Abstract: The unit is for the supply of heat exchangers e.g. for building and/or swimming pool heating, using a boiler and a heat pump. The heat pump is responsible for heating up to an external temp. of a few O deg. If the external temp. falls, below this point, the boiler is switched-in. The cooling medium condenser of the heat pump withdraws the necessary condensation heat from the ambient air, or from the boiler exhaust gas, or from an air/exhaust gas mixt. These are cooled in the condenser to a temp. just above icing-up of the heat exhanger surface.
Patent DE-2653365-A1 (DE)
Title: Photoelectric keyboard for typewriter - has LEDs supplied from astable multivibrator and clocked photosensors that set bistable via OR:gate
Inventor: MCVEY IRVIN M
IPC: B41J3/26
Filed: 1976-11-24
Abstract: Key actuation interrupts the light beam from an LED (36) to a photo sensor (38). The diode energy supply is provided by an astable multivibrator that generates a pulse every 5 milliseconds. The pulse is shaped to a 50 microsecond pulse and gates a supply transistor. When a key is actuated an OR gate generates an output to set a bistable. The bistable output is gated by a clock signal to operate a counter to generate an output after 89 msec. The flip-flop is then reset and key states clocked into a shift register. The shift register output may be recorded and finally converted. The locked gating system ensures that correct information is recorded.

Title: Echo sounder with sensitivity control - stores amplifier output corresponding to max. echo on capacitor for gain control during succeeding cycle
Inventor: DOBRITZ GUENTER DIPL ING
IPC: G01S7/529
Filed: 1977-02-22
Abstract: The echo sounder determines the propagation time between the sending out of an ultrasonic pulse train and the arrival of a reflection as the measure of the distance travelled by the sound. The gain of the selective receiver amplifier (6) is electrically adjustable. The maximum reflection voltage between two transmitted pulse trains is alternately stored as the test value on one or the other of two capacitors (14, 15). During the succeeding cycle each capacitor is connected to a further capacitor (16) whose voltage serves as the measured value for a controller (17, 18) of known design. The controller alters the amplifier's (6) gain by means of a correction voltage, that the maximum value of reflected voltage is automatically set to a required value.
