Patent DE-3916409-A1 (DE)
Title: Portable data-transmitting and receiving device
Inventor: OKUYAMA TOSHIHARU
IPC: G08C17/00
Filed: 1989-05-19
Abstract: A receiver receives from a measuring device measured values which have been recorded on an object to be measured and are transmitted, together with a data type for identifying the device, as a radio signal. The measured value and the data type, which have been received, are displayed on a display unit for a predetermined length of time and stored in a memory. By comparing the measured value which is displayed on the measuring device with that displayed on the display unit it is possible to verify whether the measured value and data type have been stored correctly. By means of a cancel key the measured value and the data type, which were stored last, can be cancelled. The measured values received from the measuring device, and the measured values entered by means of the keyboard as well as the data type of the measuring device, are displayed on the display unit for a predetermined length of time and stored in the data memory. When pressing a transmit key, all measured values stored in the measuring device can be transmitted, together with their data types, to a separate data processing unit. <IMAGE>

Title: Gas-gas heat exchanger with intermediate heat medium - is divided into stacked modules parallel to direction of gas flow, which project into gas flows
Inventor: SCHILLING HEINZ
IPC: F28D15/00
Filed: 1990-07-27
Abstract: Air conditioning plant incorporating heat exchangers which depend upon gaseous contraflow, has a prim. energy requirement. The novelty is that the heat exchanger is subdivided into stacked modules parallel to the direction of gas flow which project into both gas flows. Each module is comprised of numerous tubes at right angles to the gas flow, each of which bears numerous heat conducting fins which are parallel to the gas flow and form a single surface from front to rear. The fluid intermediate heat carrier medium alternately crosses both gas flows, againt the flow of the warmer gas towards the warm gas inlet. The intermediate heat carrier is warmed in an oscillating cycle. The main flow direction of the warmer gas is reversed at the hot gas inlet and cold gas outlet. USE/ADVANTAGE - A simple version of this arrangement achieves 50-80% heat exchange efficiency with a min. of prim. energy requirement, and function without fluoro-hydrocarbon gases.

Title: Shaping keratin fibres, esp. human hair or wool - involves rinsing after redn. with aq. soln. of inert substance limiting increase in dia. of fibres
Inventor: HOECKER HARTWIG PROF DR RER NA
IPC: D06M11/50
Filed: 1991-02-02
Abstract: In the shaping of keratin fibres, fibres are (a) treated with a soln. contg. a reducing agent to break the cystine bonds in the fibres, (b) rinsed, (c) treated with an oxidising agent to re-form the cystine bonds, and (d) rinsed. After step (a) the fibres are rinsed with an aq. soln. of a substance inert to the fibres, so that at no point in the rinsing is the dia. of the fibres more than 30% greater than at the end of the redn. step. At no point in the rinsing is the dia. of the fibres more than 10% greater than at the end of the redn. stage; pref., there is no increase in dia.. Rinsing causes a redn. in the max. increase in fibre dia. of at least 20% (at least 50%), w.r.t. rinsing with water. Rinsing soln. has an osmotic pressure, w.r.t. water, at 25 deg.C, of 6-380 x 10 power(5) Pa, and is an aq. NaCl soln., esp. contg. 10-350g NaCl/l. After the start of the rinsing with the soln. of inert substance, water is added (dis)continuously to reduce the concn. of the inert substance, until rinsing is with water alone, or rinsing with the soln. of the inert substance may be followed by rinsing with water. Inert substances may be physiologically acceptable Na, NH4, K, Li, Mg, or Al salts (pref.  chlorides, bromide, sulphates, acetates, citrates and/or lactates), betaine, ethanol, glycerol, and/or D-sorbitol. USE/ADVANTAGE - Fibres are human hair or wool, and the process is esp. used in permanent waving of hair, but may also be the fixing of wool flat goods, or the permanent pleating of clothing. Damage to the fibres is reduced.

Patent DE-4106015-A1 (DE)
Inventor: HEIMBERG WOLFGANG DR ING
IPC: F02M51/04
Filed: 1991-02-26
Abstract: A fuel injection device (5) for internal combustion engines has an injection nozzle to which fuel is supplied by means of a pressure device comprising a fuel-accelerating pump (1) and a fuel-retarding device (6) which, when activated, convert the kinetic energy of the accelerated fuel abruptly to a pressure shock wave which causes the fuel to be sprayed through the injection nozzle (5). According to the invention, an intermittently operated fuel-accelerating pump (1) is used. This pump (1) and the preferably electrically operated retarding device (6) are preferably controlled by a common control device (8). As a result, the injection device can be operated with very little, optimally utilized energy and can inject fuel in a precisely controllable manner very quickly and when decoupled from the motorized operations.
