Patent DE-4235453-A1 (DE)
Inventor: MUELLER WERNER DIPL ING
IPC: H04B17/382
Filed: 1992-10-21
Abstract: In radio transmission systems having a number of radio channels available for transmission, it is necessary to recognize a transmission channel as idle. One known way of doing this is to measure the field strength on the transmission channel and carry out a threshold decision. As soon as the field strength in a transmission channel is below a preset value, this transmission channel is recognized as idle. In measuring field strength, the field strength is averaged over the entire bandwidth of the transmission channel. As a result, a transmission channel that experiences interference from the signals on its adjacent channels may not be recognized as idle, although the adjacent-channel interference has little effect on the transmission quality. The new method makes it possible to recognize the signal present in a transmission channel by means of numerous narrowband field strength measurements. The transmission bandwidth can then be better utilized, as especially adjacent-channel interference and other forms of interference occuring only at the upper and lower ends of the frequency range of the transmission channel are recognized without the transmission channel's being recognized as occupied. The method as per the invention can be used in all radio transmission systems with independent channel search.

Title: Pumpable light-weight concrete mixture
Inventor: HENNEK PAUL DIPL ING
IPC: C04B40/00
Filed: 1993-05-06
Abstract: There is a light-weight concrete mixture in which cement, water, a stony light-weight expanded material and an additive comprising haemoglobin and cellulose are mixed together. It is here desirable to have a readily pumpable light-weight concrete mixture in which, owing to the additive, the density of the light-weight concrete mixture and the grain density of the light-weight expanded material used can be then considerably reduced and the properties of the light-weight concrete formed from this light-weight concrete mixture are very considerably improved. This is achieved by the additive being provided in an amount of 0.1-10 parts by weight based on 1000 parts by weight of added water and by, for 100 parts by weight of haemoglobin + cellulose, the haemoglobin being provided in an amount of 10-35 parts by weight and the cellulose in an amount of 90-65 parts by weight, with the pore air content being at most 10% by volume. The composition and measuring in of the additive comprising haemoglobin and cellulose makes a light-weight concrete mixture pumpable without blockages using a hydraulic concrete pump applying a certain maximum pumping pressure, while the mixture would not be pumpable without the additive owing to blocking.

Patent DE-4335880-A1 (DE)
Title: Infinitely variable gearing with endlessly rotating transfer member - uses simultaneously moving bevel wheels and counter member to  displace transfer member to adjust translation ratio.
Inventor: RODE CARSTEN
IPC: F16H9/24
Filed: 1993-10-18
Abstract: The translation ratio is changed by displacing a transfer member through a pair of cogged bevel wheels which are arranged axially parallel mirror-reversed but do not engage with each other. The transfer member can be fixed by counter members matching the shape of the bevel wheels. The counter member and bevel wheels move on two parallel axes opposite each other simultaneously so that when the effective translation dia. on one axis is reduced that on the other is simultaneously increased, and vice versa. The force transfer is produced through the keyed and force- locking engagement between the transfer member and the pair of bevel wheels/counter member. The transfer member flexibly adapts to the shapes at the intersection between the wheel and counter member thereby determining the contact pressure and translation ratio. USE/ADVANTAGE - Simplified mfr. and assembly of infinitely variable gearing assembly without the use of expensive control devices to apply the contact pressure.
