Title: Spraying device for bottle cleaning machines
Inventor: BECHLER KURT
IPC: B05B1/26
Filed: 1988-11-18
Abstract: The object of the invention is to prevent and/or delay the obstruction of spraying nozzles in spraying tubes between cleaning cycles by modifying the flow conditions, i.e. to bring about self-cleaning of the spraying nozzles. According to the invention, the object is achieved in that bodies which generate turbulence are arranged, 180@ offset with respect to the spraying nozzles, in the region of the spraying nozzles inside the spraying tubes. Each of these bodies is a bolt which is screwed, beyond the central axis, into the spraying tube or is situated on a bolt strip which passes through the spraying tube. The bolt is arranged axially or immediately upstream or downstream of the nozzle bore in the direction of flow of the spraying liquid. The bolt has a slope at its upper end, especially a groove which has a twist. The invention is used in bottle cleaning machines and relates to a spraying device having fixed or movable spraying tubes which have spraying nozzles. <IMAGE>

Title: Arrangement for on-line measurement of physical, chemical and biological process variables
Inventor: APEL LUDWIG DIPL ING DR
IPC: C12M1/26
Filed: 1988-12-16
Abstract: The invention relates to the measurement of process variables in complex liquid medium and can be used in biotechnology, medicine, agriculture and environmental protection. The aim of the invention is to measure a process taking place in a biological system, e.g. in a bioreactor, more completely than hitherto and to set up the conditions for substantial automation and optimisation of the process according to biological target variables. This is achieved according to the invention by providing, for sterile removal of biological material in liquid form, a separation component which is outside the biological system and is connected thereto, by a module for preparing the sample being connected to the separation component, by means being arranged for measurement of the samples in parallel or series, with those means for sterile measurement of the sample being arranged upstream of the module and means for non-sterile measurement of the samples being arranged downstream of the module, and by assigning to the abovementioned components a transport system for transporting the samples. <IMAGE>
Patent DE-3901158-A1 (DE)
Title: Directional microphone
Inventor: BSCHORR OSKAR DIPL ING DR
IPC: H04R1/38
Filed: 1989-01-17
Abstract: The invention relates to a directional microphone (M) having a tube which forms a microphone attachment (2) and the wall of which exhibits perforations (4), a sound sensor (1), for example a pressure microphone, being arranged in the tube. In addition, a wind protection (5) is provided for the directional microphone. In order to be able to use the directional microphone, especially at high free stream velocities as, for example, in the case of sound recordings from the air from an aircraft, the sensitivity of the directional microphone can be improved by the microphone attachment being constructed as horn conductor (2). This results in a sharper directional beam with the same constructional length. Furthermore, the horn part which is tapered in the direction of the flow has a thinner boundary-layer thickness and is thus more insensitive to wind noises. An additional reduction in the interferring noise is given by sheathing (5) the horn part (4) with small hairs (6) which are inclined in the direction of flow (A). <IMAGE>
