Patent DE-2243348-A1 (DE)
Title: Electronically regulated chlorine dispenser - for drinking water treatment
Inventor: LORANG OTTO
IPC: C02F1/76
Filed: 1972-09-02
Abstract: The Cl content of the water is sensed by a pair of redox potential sensing electrodes whose output is applied to the non-inverting input of a first op. amp. used as impedance converter, the reference electrode in the measuring cell being fed from a potential divider across the supply rails of the equipment. The output of that amplifier feeds a second op. amp. inverting input and this is zeroed by a manually controlled input at the non-inverting terminal when the electrodes are in chlorine free water. The output of the second amp is an analogue of Cl content and is displayed or recorded and also drives an inverse proportionality frequency generator whose pulses drive the dispenser pump. Accurate and fast, smooth response.

Inventor: GLASER WILLY DR ING
IPC: B01D50/00
Filed: 1973-04-28
Abstract: These methods and their wet separator, mainly for keeping air pure from metal oxide-contg. waste gases, comprise the use of sulphide additives to the scrubbing liquor for conversion of disperse and/or aerosol type oxides of Fe, Pb, Zn Cd Hg, Cu and other heavy metals into their amorphous, adhesive, flocculating sulphides, which can carry down or agglomerate their associated dispersoids, which themselves can form no sulphides, e.g. C black, SiO2 and/or prods. of the dry distn. and/or incomplete combustion of fuels, opt. in conjunction with other combustible materials e.g. refuse.

Patent DE-2335658-A1 (DE)
Title: Dynamometer ring with three vertical supports - are rectangular cross-section and uniformly distributed over the periphery
Inventor: BROSA ERICH
IPC: G01L1/22
Filed: 1973-07-13
Abstract: The vertical supports and horizontal stabilising devices between them, are made in one piece with an annular measurement cell. Strain gauges on vertical parts of the above cell, suitable for compression tests, are so mounted in the middle of the wall, that their plane, depending on the milling of compression parts, lie radially. Horizontal stabilising devices are wedge shaped, so that after separation of vertical measurement columns they can be used as flexural bars clamped at one end, with nearly homogeneous surface tension, for a different measurement range. The cuts through vertical columns are limited by inserts to a permissible movement, to serve as overload protection for the horizontal flexural bars.

Title: Handle for doors or windows - has shank covering shell extended to form fixing plate
Inventor: PRACHT GUENTER
IPC: E05B3/06
Filed: 1973-11-12

Title: Liquid fuel combustion with blue, soot-free flame - obtained by feeding flue gas controllably to fresh air intake
Inventor: BECKER PAUL
IPC: F23C9/00
Filed: 1973-12-29
Abstract: Liq. fuels are combusted with a soot-free, blue flame using an atomiser nozzle for a combustion space; flue gas is taken from the space and mixed into the fresh air flowing to the nozzle to delay the combustion process. Preferably the flue gas is sucked from the space by the fresh air fan, and its amount can be regulted. The appts. has a separate flue gas channel connecting the combustion space to the fresh air channel. Combustion is influenced in the simplest way to give a stoichiometric flame. The N oxides present in the fuel can be mostly burnt, and economical heating is obtained.

Title: Aerial embedded inglass pane for motor vehicle receiver - has two passive-elements with high mutual coupling factor for UHF and long medium and short wave
Inventor: SOMMER KURT
IPC: H01Q1/12
Filed: 1974-02-09
Abstract: The aerial is embedded in a pane of glass for use with a motor vehicle receiver. The output energy of the aerial derived from the UHF band feeds into one branch of the signal amplifier and the energy derived from the long, medium and shortwave bands feeds into another branch of the amplifier. There are separate passive aerial elements for each range. These are arranged such that the mutual coupling of the two elements is very great. When the amplifier branch for the UHF range is loaded, the energy derived from the branch handling the other bands is negligible. The long, medium and shortwave branch of the amplifier uses a field effect transistor. The UHF branch has a transformer tuned to eliminate the noise.

Title: Rectangular profile marine hull - which draws in water at front and expels it at rear
Inventor: WAGNER HANS-JOACHIM
IPC: B63H11/02
Filed: 1974-05-27
Abstract: The hull has a rectangular outline when viewed from on top. The front section has water intakes (2a) on each side of the centre line leading to narrow water ducts (4a) at each side of the inside hull. Water impellers (3a) are positioned in the ducts on each side, driven from a centrally mounted engine, to expel the water from rear ducts. The hull does not cause pressure changes such as a normal hull, where water is piled up into a bow wave at the front, and with suction areas at the rear. The water drag is thus considerably reduced.
