Patent DE-3235000-A1 (DE)
Inventor: GIBBONS EDWARD J
IPC: B01F23/57
Filed: 1982-09-22
Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to a main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavouring and surface active agents, which may controllably soften the speckles on storage.
Patent DE-3238766-A1 (DE)
Inventor: KLIESCH WILFRIED DIPL ING
IPC: B23K13/02
Filed: 1982-10-20
Abstract: It is necessary to determine welding temperature as precisely as possible in order to properly control the high-frequency welding of longitudinal pipes. Changes in welding temperature are proportional to alterations in the welding current that flows through the edges of the skelp. Magnetic-field sensors can be used to directly and precisely determine alterations in the current and hence changes in the temperature. Voltages induced in the sensors can be processed into setting signals to correct the high-frequency welding generator and disruptions in the current used to generate signals to mark the site of failure on the pipe for subsequent rejection.

Patent DE-3248950-A1 (DE)
Title: Circuit arrangement for locating buried persons in accordance with the transmitter/receiver principle
Inventor: POLLINGER HANS
IPC: H01Q5/00
Filed: 1982-04-26
Abstract: This circuit arrangement contains two transmit oscillators tuned to different frequencies (2.275 and 457 kHz) and two correspondingly tuned receiving channels. The outputs of the receiving channels are supplied directly or indirectly to an electro-acoustical transducer. The coils (W1, W2) of the two transmit oscillators are located at a distance from one another on a single ferrite rod (F1), the winding capacitances of the coils being greatly reduced by insulating foils (24) arranged between the individual winding layers. This makes it possible for both transmit channels and both receiving channels to be able to operate simultaneously without interfering with one another, even though the coils are wound onto a single ferrite rod to obtain a compact device. An energy-saving functional check is also possible via an electromagnetic feedback between the antenna and the feedwires to the electro-acoustical transducer. <IMAGE>
Patent DE-3301386-A1 (DE)
Title: Nozzle arrangement on a drum loader
Inventor: WEHSER GERHART
IPC: E21C35/187
Filed: 1983-01-18
Abstract: The nozzle carriers forming components of the nozzle arrangements on drum loaders for the purpose of dust suppression have hitherto had nozzles which in the fitted state of the nozzle carriers lie at the outer end. The orifice edges of the nozzles can consequently be easily damaged during operation, so that the nozzle orifices can be pressed shut. Sludge can also collect in the nozzles when the drum loaders are stopped and cannot be flushed out upon restarting on account of the longitudinal passages widening towards the inner end as a result of the high water pressure. To rectify these problems, the invention provides for a nozzle 9 at the inner end of the nozzle carrier 1, the recess 10 which passes through the nozzle carrier 1 in the longitudinal direction widening conically from the nozzle 9. Dirt, which now collects in the conical longitudinal recess 10, can readily be flushed out. On account of the large opening cross-section MW in the orifice area of the recess 10, damage to the orifice edge can no longer lead to clogging and thus to loss of function of the nozzle 9. <IMAGE>

Patent DE-3322847-A1 (DE)
Title: Process for the stabilisation of biological cells, and biological cell compositions stabilised by this process
Inventor: CARTER II JAMES HARRISON
IPC: G01N33/96
Filed: 1983-06-24
Abstract: Compositions of biological cells are stabilised in order to avoid, by the formation of acetal, in particular cyclic acetal, an aldehyde functionality, mainly for preventing the linkage of cells. The stabilised biological cells are suitable in particular as analogues for human haematocytes in reference or control reagents as they are used in electronic haematological test apparatus. In a process for the preparation of acetal-stabilised biological cells, biological cells which have been treated with polyaldehyde are reacted with alcohol, in particular 1,2-diol, under acidic conditions; the reaction solution formed is then rendered basic for stabilising the acetal formation on the biological cells.
Patent DE-3325958-A1 (DE)
Title: Method for the continuous fixing of reactive dyes
Inventor: FEESS ERICH DR
IPC: D06B19/00
Filed: 1983-07-19
Abstract: In the dyeing of cellulose webs with reactive dyes, dye fixing without prior intermediate drying is more and more popular in practice. While wet batch processes require suitable machinery for this object and are therefore cost-intensive, in the case of fixation by wet-steaming difficulties occur again and again as a result of flucuating steam conditions and on account of condensation phenomena.   According to the invention, the existing problems are dealt with by preheating the wet material from dye application with IR or microwave radiation to from 75 DEG C to the boiling point of the liquor and then immediately thereafter steaming for 1-15 seconds with HT steam.

Title: Process for reading in and out signals based on electrically polarisable layers
Inventor: EILING ALOYS DIPL PHYS DR
IPC: G11B9/02
Filed: 1984-06-01
Abstract: An electrically polarisable polymer layer provided with a system of electrodes is used as a data memory. The electric signals to be stored are recorded in the polymer layer by remanent polarisation of individual domains. The written-in remanent polarisation is preserved even after switching off the signal field. The reading-out operation is based on a pyroelectric activation of the polarised domains. The activation is performed by a multiplicity of the polarised domains simultaneously inducing electric signals in the system of electrodes, which are then arranged and sampled in parallel and/or on the basis of a multiplex process. A strip matrix is arranged as the system of electrodes on the upper side and on the underside of the polymer layer. The strip-shaped electrodes of one side are parallel to one another, but form an angle with the strips of the opposite side. In the case of a data memory of such a construction, the polarised domains of the polymer layer assigned to a single conductor track of the strip matrix can be pyroelectrically activated simultaneously by a heating current pulse flowing in this conductor track. In this way, the polarised domains assigned to the conductor track can be sampled simultaneously and then, by changing over to another conductor track, the correspondingly other regions can be activated, so that altogether a selectively parallel read-out mode is achieved ...

Title: Optical key with light guide
Inventor: SCHOENEBECK BODO
IPC: H03M11/26
Filed: 1984-09-07
Abstract: In order to eliminate the restrictions of conventional keys in terms of function (switching reliability) and applications (environmental conditions) as well as in terms of operating duration (corrosion, changing of the material due to the effects of electric energy), the optical key with light guide uses as the signalling medium light which is conducted via a light guide to a receiving element when the key is depressed. Due to the design of the through-bores, it is possible to combine a plurality of individual keys to form keyboards. Due to the use of light guides for feeding in and carrying away the optical signals, the decoding electronics can be installed away from the key field. As a result, since the use of electric pulses for information input within the key has been dispensed with, applications are possible in areas where, in the conventional manner, it would be feasible only with considerable extra expenditure (for example under water).
