Title: Boiler scale prevention and dissolution - by replenishing with fresh natural water
Inventor: RITTLER GUSTAV
IPC: C02F5/00
Filed: 1980-10-16
Abstract: Scale deposits in boilers are prevented and existing deposits are removed without the addition of any chemicals or the use of ion exchanger resins by purely physical principles, utilizing the inherent dissolving power of natural fresh water. If the natural water contains exclusively carbonates, up to 2% of the boiler water is drained off per day and replaced by fresh water. In the case of water with a high gypsum content, the percentage rises to 4%. If scale deposits are already present, a boiler which is not used at night is emptied from the highest to the lowest water level and replenished with natural water. This offers a simple and low-cost method.

Filed: 1981-01-30
Abstract: A powder compact material in the form of a stick for cosmetic purposes is made up of powder-like base materials and if necessary additions of binders, lubricants and materials increasing adhesion compacted or bonded together as a body which keeps its form. For stopping the end or outer face of the stick-like body becoming clogged with moisture and sebum on use (so that clean powder compact material would have to be uncovered by cutting, this wasting the material) the compact stick contains as part of the present invention, a particle material, whose particles are harder than the particles of the base materials. The hardness of the particle material may preferably be equal to at least 4.0 on the Mohs' hardness scale. A particle size of 10 to 50 microns and an outer face of the particles which as far as possible is jagged or otherwise rough is responsible for useful effects. Particle materials which may be used are more specially pumice powder, quartz flour, aluminum oxide (corundum) metal carbides, metals and the like, and mixtures thereof. The level of the particle material is more specifically 20 to 40% of the overall weight of the compact material.

Patent DE-3123072-A1 (DE)
Title: Title device
Inventor: KRAUSE WALDEMAR DIPL ING
IPC: G03B27/62
Filed: 1981-06-11
Abstract: The invention is based on a title device for films, videos and series of slides, with a frame for receiving text and images, which as a rule take the form of rigid devices. The improvement of such a title device is characterised in that the reception frame (1) is pivotably mounted on a bearing plate (10) by means of pivot joints (3). This has the advantage that the camera and the title device can be aligned with one another and that tilting, distortion etc. can therefore be avoided. Furthermore, the versatility of the device means that users have a multiplicity of types of image at their disposal. For example, a transparent film stretched across two running title rollers (8) can be used to record a text passing through the image. Furthermore, folding titles can be recorded without interruption of the film running in the camera simply by folding them down in display holding clamps (12a) on a shaft (12) provided for the purpose. The same applies to the turning plate, on which two items to be displayed can be mounted and which can be turned vertically or horizontally while the film is running, depending on the type of clamping. <IMAGE>

Title: Receiver for pseudo-randomly phase-modulated signals
Inventor: GRUENBERGER GERHARD DR ING
IPC: H04B1/707
Filed: 1981-08-06
Abstract: In a receiver in an information transmission system operating with pseudo-random phase shift keying, a detector in a basic Costas configuration followed by an optimal arrangement is used for deciding whether clock pulses of the clock-controlled pseudo random noise generator in the receiver are masked out or not for the pseudo-random code acquisition. By masking out clock pulses, a displacement is formed between the received pseudo random sequence and the pseudo random sequence generated in the receiver and to be synchronised, without detuning the clock frequency. The invention results in a more rapid acquisition of synchronisation. A receiver designed in accordance with the invention is used in interference-proof spread-spectrum information transmission systems which operate with pseudo-random phase shift keying. <IMAGE>

Title: Circuit arrangement for a controllable current source
Inventor: ELSCHNER HORST PROF DR SC TECH
IPC: G05F3/22
Filed: 1981-10-02
Abstract: The invention relates to a controllable current source, the output current of which follows a control voltage up to a maximum amount, stays at this value when the control voltage is increased further and, if nothing is connected to the control voltage input, assumes a predeterminable value below or equal to the maximum amount, preferably in integrated technology, for example for brightness or volume controls. The object of the invention is the creation of a controllable current source with intermediate-value adjustment with a high-impedance circuit connected to the input and a maximum current, even when the control voltage is exceeded which corresponds to the maximum current. According to the invention, this object is achieved by the fact that the current balancing circuit precedes the base of the input transistor via one or several diodes, the resistance of the current balancing circuit being dimensioned in such a manner that the base current of T2, multiplied by the current gain factor, is greater than the base current of the input transistor.

Title: Method for trunking sound broadcast signals
Inventor: ASSMUS ULF DIPL ING
IPC: H04H20/81
Filed: 1981-11-24
Abstract: In a CCITT-recommended data flow of 34.368 Mbit/s of a non-hierarchical multiplex system, not only 48 sound broadcast signals, each coded with 14 bits, and the signals required by the system are to be transmitted, but, in addition, channel-individual information providing signalling for voice/music, stereo/mono, traffic broadcasts, transmitter identification, time, programme identification etc., should also be transmittable. For this purpose, 50 time slots (Z1 to Z50), each comprising 21 bits with an additional 2 x 12 bits for synchronisation and signalling, are interleaved according to the invention to form a pulse frame of 1074 bits. Through this division of the pulse frame, the high clock frequency is divisible by three. As a result, low-power-consumption integrated circuits and read-only memories (PROM) can be used to the maximum extent to generate the signals required for multiplex formation. In each time slot, 6 bits are provided for channel-individual information transmission and a parity bit for protection of the 7 or 8 most significant bits of the sound broadcast signals. Two time slots are available as service and test channels. <IMAGE>
