Title: Lavatory wall and floor protection from urine - involves fluid or compressed air screen across urine spray track
IPC: E03D9/00
Filed: 1980-11-07
Abstract: Improved hygiene and cleanliness is attained in the vicinity of sanitary devices where urine is excreted, such as urinal basins and lavatory pans, where adjacent walls or floors may be accidentally sprayed with urine. A screen consisting of liquid or compressed air, is generated in front of the wall concerned, transversely to the normal direction of jets or urine. This can involve an intake duct connected to a fluid supply and to a spray, located above the basin bottom, to spray fluid horizontally, with a valve between spray and supply. This design provides a simple and effective protection of lavatory equipment.

Title: Converter control system for synchronous machine - uses non-reversible model with stator current components passed to coordinate rotating devices
Inventor: FINK RUEDIGER DIPL ING
IPC: H02P21/08
Filed: 1980-11-12
Abstract: The method uses an equivalent model of the synchronous machine, there being three return paths for three supply controllers. These have control inputs for the torque, phase angle, voltage and current, with outputs for the components of the stator current and the field current. The two components of the stator current corresponding to the motor position are passed to a coordinate rotating device and transformed so that either the rotor position is directly given or the rotation between current and rotation is obtained. The model is non-reversible, and a second voltage model can be used to determine the values of the components of the stator voltage. These can be processed by a coordinate rotating system giving the voltage components from the stator at its outputs.

Title: Sail-board dagger board box - has one guideway edge tangential to hull recess edge, with board trunnions deformed to enter
Inventor: MARKER HANNES
IPC: B63B35/79
Filed: 1980-12-02
Abstract: The sailboard dagger board box has guideways in the box sidewalls through which board trunnions pass to house, rotatably, in saucer-shaped bearing recesses. The guideways (3) have one edge tangential to the recess (5) and the trunnions (4) are deformed elastically to enter them, ensuring retention. The trunnion cross-section is roughly semircular, the peripheral portion at the ends at least being of rubber or elastomeric material. Sloping ramps (7) in the recess bottom opposite the junction (8) between its periphery (6) and the non-tangential guideway edge cause that junction to act as a detent to baord insertion and extraction.

Title: Lavatory bowl with warm air jets - which are arranged to create vortex for more effective drying of user's body
Inventor: BAUS HEINZ GEORG
IPC: E03D9/08
Filed: 1980-05-24
Abstract: The toilet bowl or bidet is fitted with nozzles (52,54) which direct jets of warm air which are used to dry the lower part of the user's body. A pump (44) installed behind the lavatory seat (10) supplies warm air to two pipes (48,50) which terminate in nozzles (52,54) immediately below the seat on the opposite sides of the bowl. The nozzles direct the air radially inwards, and when the two jets of air meet they create a vortex in the lavatory bowl which dries the user's body parts. With existing appliances of this type, where the jets are arranged tangentially, they tend to pick up water from the bowl and so are less effective in drying than is the case with this design where a vortex is created.

Title: Circuit arrangement for telephone subscriber stations with a microprocessor
Inventor: DROSSEL MICHAEL ING GRAD
IPC: H04M3/32
Filed: 1981-01-31
Abstract: The test current supplied from the exchange during the connection of a subscriber station to a line concentrator device, which lies below the power consumption of a microprocessor, is intended not yet to initiate switching processes in the station itself, since these switching processes must only take effect when the subscriber concerned has replaced his handset and normal feed current is applied to the telephone wires. This is ensured by connecting a threshold value component upstream of the microprocessor which monitors both the replacement of the handset on the station concerned and also the provision of an adequate operating voltage for the microprocessor. Only when both conditions are satisfied is the microprocessor activated and able to control the necessary switching processes in the station.

Title: Frame for push-in electrical assemblies
Inventor: NIGGL HEINZ
IPC: H05K7/14
Filed: 1981-03-30
Abstract: The mounting frame has guide rails (1) for guiding and holding electrical push-in units. The guide rails (1) are held on rail-like supports (3) of the frame, which supports (3) extend transversely with respect to the guide rails (1). The supports (3) have rectangular perforations (4), which are arranged in a row with respect to one another and into which sprung latching tabs (5) on the guide rails (1) engage. The guide rail (1) is slotted centrally and longitudinally between each pair of latching tongues. The longitudinal webs (8) which are produced support the latching tabs (5) whose necessary lateral deflection during insertion into the perforations (4) is made possible by the elastic flexibility of the longitudinal webs (8). In consequence, the attachment of the guide rails (1) to the supports (3) is considerably simplified. <IMAGE>

Title: Table on seats
Inventor: WALTER KURT
IPC: A47C7/68
Filed: 1981-04-29
Abstract: The invention relates to a table on seats, in particular in vehicles of all types, the seats being arranged individually or in pairs in rows one behind the other, and each table being able to be moved from a position of rest or non-use which does not interfere with the space into a position of use which can easily be reached by the respective seat user, and vice versa. In order that the table can be moved into an absolutely non-interfering position, it is proposed that the table (8) be linked directly or indirectly transversely to the seating direction in a hinge-like manner on the seat frame (2) on the side of the seat (1) or between the seats (1) in the case of seats (1) being arranged in pairs, that is to say in the case of double seats, and that the attachment arm (5) and axis of rotation (cf. 18) be selected such that, with a convenient position of use of the table (6), the latter can be folded into the free space (13) below the seat (1) or seats (1). <IMAGE>

Title: Plant for the sterilisation of products, e.g. milk
Inventor: BRUECK ALBIN
IPC: A23C3/033
Filed: 1981-05-16
Abstract: The invention relates to a plant for the sterilisation of liquid products, e.g. milk, with a forced circuit (product circuit II) carrying the product and a counter-current forced circuit (heat transfer medium circuit I) carrying a liquid heat transfer medium, e.g. hot water, the two circuits (I and II) being in heat exchanging relation to one another via common heat exchangers, namely a pre-heater (3), a downstream secondary heater (5) and a cooler (6), and the cooler (6) reducing the temperature of the sterilised product to the temperature intended for introduction of the product into the packaging, and a heater (7), which is preferably fed with steam, being arranged between the secondary heater (5) and the cooler (6), which heater (7) heats the unsterilised product to the desired sterilisation temperature, different pressures prevailing in the two circuits (I and II). In order to prevent passage of the heat transfer medium into the product circuit wherever possible and, if passage nevertheless occurs for whatever reasons, to indicate this to the plant operator without delay it is proposed, according to the invention, that precautions be taken to ensure that the pressure at every point in the product circuit (II) is higher than that in the heat transfer medium (I) and that a display device (10), by which occurrence of product in the heat transfer medium circuit (I) can be detected, is connected to the heat transfer medium circuit (I). A display device is expediently arranged in the condensate line of the heater fed with steam. The display device is advantageously a conductance measurement device. <IMAGE>

Title: Shielding arrangement for the storage, in particular intermediate storage, and transport (shipping) of spent nuclear fuel elements
Inventor: BAATZ HENNING DR
IPC: G21F5/10
Filed: 1981-08-06
Abstract: The invention proceeds from a shielding arrangement for the storage, in particular the intermediate storage, and the transport of spent nuclear reactor fuel elements. The shielding arrangement consists of a transport and storage container made from cast iron (in particular spherulitic cast iron), and of a device for neutron shielding. The lateral surface of the flask has cooling ribs cast on externally. The device for neutron shielding consists of a cylindrical lateral surface which is mounted on the cooling ribs and forms cooling ducts together with the cooling ribs. In the region of the transport and storage flask base, the lateral surface of the cylinder has inlet openings for cooling air which provide the cooling ducts with cooling air. The cooling ducts are, of course, open at the top. As a result, the transport and storage flask can be produced in a substantially simpler way and be finished more easily than a transport and storage flask made from cast iron or cast steel, in which the device for neutron shielding consists of bores or ducts for neutron-absorbing or moderating material in the lateral surface of the flask. <IMAGE>

Title: Electroplating bath for producing uniform Fe-containing layers and structures having very good magnetic properties
Inventor: WAGNER UDO DIPL CHEM DR
IPC: C25D5/00
Filed: 1981-09-21
Abstract: In the specified electroplating bath a facility for automatically monitoring and controlling the bath is provided at the same time by as small a number of bath components as possible. This increases the operating reliability of the bath. According to the invention, an electroplating bath has a high concentration of Ni and Fe ions to be discharged, combined with citrate and/or citric acid as main additive, and a pH of about 4.0. Only two types of additives, in particular, are required. An electroplating bath for producing uniform Fe-containing layers and structures having very good magnetic properties is operated, according to the invention, in such a way that the bath solution is irradiated with UV light, thereby reducing Fe(III) ions. This makes it possible to control an electroplating bath for producing uniform Fe-containing layers and structures using an automatic control circuit. <IMAGE>

Title: Underwater sound receiver with optical fibre
Inventor: SCHULZ-DUBOIS ERICH-O PROF DR
IPC: G01H9/00
Filed: 1981-12-05
Abstract: Starting with an underwater sound receiver, known from US Patent Specification 4199139, having a first optical fibre exposed to the sound waves to be received and a second optical fibre which is shielded against the sound waves, to both of which polarised light is applied at their input faces and the output faces of which are coupled to an optical heterodyning device, the influence of slow temperature or pressure fluctuations in the surrounding water is to be suppressed. For this purpose, an orthogonal polarisation divider is arranged in the beam path of the light beams coming from the two optical fibres and combined in the heterodyning device, the two output light beams of which divider impinge on one photodetector each. Each of the two photodetectors is followed by a differential amplifier, the other input of which in each case receives a direct voltage (u0) of the magnitude of the mean value of the photodetector output voltage (u1, u2). The output of each differential amplifier is connected via a low-pass filter to one input of one of two multipliers. The other input of each multiplier is connected to the input of the low-pass filter not preceding it. The outputs of both multipliers are connected to the two inputs of a differential amplifier which supplies at its output a signal (u22) corresponding to the phase difference.
