Patent DE-2742694-A1 (DE)
Title: Drum filter sieve for fluid waste disposal units - has drainage openings in scraper unit ensuring max. removal of water from waste
Inventor: MEFFERT ERNST
IPC: B01D33/00
Filed: 1977-09-22
Abstract: Downwardly inclined chute surface (4) of the horizontal sieve drum acts as a scraper device and has one or more orifices (6, 8) through which the waste fluid can pass wherein a baffle plate (10) is provided beneath the openings to lead off the fluid. Although the dwell time of the material to filtered on the drum is slight most of the residual water can be removed from the material. This is more easily achieved if the opening is designed as a gap which runs across the width of the chute face with slits or grooves opening into this gap from above. The baffle plate can then be a sharp lower defining edge of the gap.

Title: Continuously operating timber drying oven - uses blowers and heat exchanger for circulating drying gas
Inventor: PFISTERER ROLF
IPC: F26B21/02
Filed: 1978-06-28
Abstract: The continuously operated drying oven is used for timber drying. The gaseous drying fluid is circulated by blowers ensuring mass exchange and removal of the moisture drawn from the timber. The drying system has high efficiency and compact design with relatively low energy consumption of the blowers. Transverse flow blowers are used for circulating the gaseous drying fluid. The axes of the transverse flow blowers are vertical and the timber moves horizontally through the drier.

Patent DE-2833048-A1 (DE)
Inventor: HAENSEL ECKHART
IPC: H04L12/50
Filed: 1978-07-27
Abstract: In a circuit arrangement for a program-controlled switching centre (EDS), the aim is to relieve effectively the load on the switching centre (EDS) in terms of the identification and processing of signalling data. For this purpose, the signalling data are checked in monitoring circuits (MC1 to MCn) containing microprocessors (CPU) for the presence of specific bit combinations in order to transmit alarm signals to the switching centre (EDS) if such bit combinations are present. Corresponding signalling data can be transmitted under the control of the microprocessors (CPU) when instruction signals arrive from the switching centre (EDS). The main use of the circuit arrangement is in the field of program-controlled data switching. <IMAGE>

Title: Boggy soil homogeniser - with feed capstan, revolving cutter and pocket for collecting hard solids
Inventor: STAUDACHER ERWIN
IPC: C10F7/02
Filed: 1979-03-14
Abstract: Boggy soil is converted to raw material for mud baths by a feed capstan and a revolving serrated cutter in a common housing. Revolving cutter co-operates with a stationary serrated cutter. Housing has an opening with a pocket just before the cutters engage each other; solids (stones) are thrown by centrifugal action into this pocket and are removed from time-to-time. This is a simple way of keeping hard solids clear of the cutter blades so that their life is prolonged and fragmentation efficiency is not impaired.

Patent DE-2916710-A1 (DE)
Inventor: KROL THIJS
IPC: G06F11/10
Filed: 1979-04-25
Abstract: A memory in which each word location for a user word not only contains the bit locations for the actual data but also one parity bit for the parity over the entire word location and one correction bit. A fixed number of word locations are grouped to form a memory location for the storage of a memory word. When a word location is read by a data user, the parity bit indicates whether the word location contains none or one bit error. If the user word contains an error, the other word locations of the same memory location and also the associated correction bits are read to correct one arbitrary bit error in the memory word. In given cases, a plurality of bit errors can be corrected if they are situated in bit positions of the same rank within the word locations for the user words. The chance that a multiple error has exactly this configuration can be enhanced by a suitable arrangement of the bit locations in a memory. Thus, a limited amount of redundancy suffices in many cases. Memory words in different memory banks may have correction bits in common.

Title: Vessel interior enamelling - by compressed air displacing enamel slip into it through riser (ZA 13.8.80)
Inventor: KAEMPER GERHARD
IPC: C23D5/02
Filed: 1979-06-01
Abstract: Hollow vessels, such as hot water tanks or heat exchangers are coated on the inside with enamel by connecting the vessel to a riser in the tank contg. the enamel slip. The slip is displaced up the riser by applying compressed air to the tank. Any surplus slip can flow back to the tank through the riser when the pressure is removed. This is a simple method of ensuring a satisfactory and uniform enamel coating on hollow-vessels. The closed system prevents during out of the enamel slip and cleaning is needed only rarely. No pumps which are likely to wear are needed.

Title: Remote gain control circuit for radio and TV - reduces volume faster than it increases volume by use of up=down counter using different frequencies
Inventor: SHIBUYA TOSHIFUMI
IPC: H03G3/02
Filed: 1979-08-31
Abstract: The gain-control circuit has a bidirectional counter (25) counting clock pulses up and down and generating an output signal depending on the number of clock pulses counted in order to control the attenuation of a variable attenuator (1-4). An oscillator (26) is controlled by the contents of the up/down counter and generates clock pulses of different frequencies for passing to the counter. The advantage lies in the ability of the circuit to reduce the volume much more rapidly than it increases it.

Title: Instantaneous fuel consumption measurement for vehicle - using flow dependent resistance and DC motor speed sensor
Inventor: ARGAUER HERBERT
IPC: G01F9/02
Filed: 1980-09-25
Abstract: A fuel consumption measurement device for vehicles with speed and fuel flow measurement sensors and a fuel consumption indicator is simply constructed, easily fitted, and gives accurate measurements of instantaneous fuel consumption dependent on speed. The speed is measured using a generator which produces a speed dependent voltage. The fuel flow measurement device contains an electrical resistance which varies with throughput. The fuel consumption indicator is a current measurement instrument producing a needle deflection according to the current passing through it. The speed dependent voltage is divided by the fuel flow dependent resistance to give a current corresp. to the reciprocal of fuel consumption. A conventional d.c motor placed between the gearbox and tachometer shaft can be used to produce the speed signal.
