Patent DE-2642134-A1 (DE)
Title: Time saving signal transmission - transmits at faster rate than inflow of data to economise carrier usage time
Inventor: GARDNER HAROLD M
IPC: H04B1/66
Filed: 1976-09-18
Abstract: The data is transmitted through a carrier system over long distances, and the cost is reduced by reduction of the time needed for transmission, i.e. the amount paid for the use of the carrier for a specific period of time. The signal representing the data is accepted and processed at a speed greater than that with which it is generated. The initial signal may in the form of a low frequency signal such as speech or music, which may be converted to frequency modulation of a carrier for line, radio, or laser beam transmission, at a fast rate, followed by reconversion at the receiver. The signal, from the generator, is recorded on the first sub carrier. The transmitter recording from the 1st subcarrier is played back to regenerate the original form of the signal and is delayed by a corresp. on equal amount.
Patent DE-2654035-A1 (DE)
Title: Mixer valve esp. for two components - has two opposed valve plungers separated by adjustable spacer rod
Inventor: KOESLING BERND ING GRAD
IPC: F16K11/048
Filed: 1976-11-27
Abstract: Appts. for mixing gases or liqs. is intended esp. for two components and comprises a mixing chamber with two separate gas inlet ducts and valves in each of these ducts; when one valve is open, the other valve is closed and vice versa. One valve is closed by the pref. conical end of a valve spindle, while the other valve is closed by the pref. conical end of a spring-loaded piston acting in the opposite direction; a rod of adjustable length is mounted inside the piston and projects beyond its conical tip, thus constituting a slender projection beyond the tip of this valve closure; the end of this rod is in contact with the conical end of th efirst valve closure comprising the spindle. Thus, when one valve closure plunger moves in one direction, closing the valve, the other moves in the same direction and opens the opposite valve, and vice versa. The rod passes with considerable surrounding clearance through the mixing chamber. Used for mixing gases or liqs. esp. two components. The two valve plungers operate positively without any backlash between them and permit one valve to be completely closed while the other is completely open, while also permitting a selectable cross-section in both of them.

Title: Chenille yarn fabric mfg. - uses mechanical fixing agent to secure yarn cladding to the core
Inventor: LEUZE HELMUT
IPC: B32B5/26
Filed: 1976-11-30
Abstract: In the mfr. of a fabric using chenille yarns, a mechanical fixing agent is used to secure the yarn on one or both sides of the material, either wholly or in part. Process ensures that the core and cladding strands of the yarn remain bonded to each other, so that a fabric can be developed from chenille yarns efficiently and economically. The fabric can be composed of Raschell chenille yarns, and the finished fabric need only be composed partly of chenille yarns. The fixing agent to bond the yarns is thermoplastic and/or chloroprene, a plastic suspension, or silicone rubber.

Title: Internally splined shaft for universal joint - has forged tubular blank with stepped bore pressed on splined mandrel
Inventor: HOLZAEPFEL ELMAR
IPC: B21K1/30
Filed: 1977-01-20
Abstract: The internally splined shaft (2) forming part of a universal joint is made from a tubular blank which is first forged to form a collar (4) near one end. The bore of the blank is stepped so that the bore at the flange end is slightly greater than the max. dia. of the splines (3). The blank is then pressed or forced by a forging hammer over a mandrel which has splines cut on its surface. This method of making internally splined components is cheaper than machining or extruding. At the same time a much better grain structure is produced in the material resulting in a higher strength shaft.

Abstract: The fully automatic watering and/or fertilization system features the control of the feed of the water and/or a fertilizer solution. A watering and/or fertilizing process can then always be started or finished when a monitored parameter achieves a preselected minimum or maximum value. As measuring parameter, the weight of a comparison substrate in a central dish is used. The feed of the water and/or the fertilizer solution to the cultures is switched on or off when the weight of the substrate reaches a given maximum or minimum value.

Title: Time constant setting for audio equipment with AGC - varies feedback time constant according to input and output levels
Inventor: SZOKOLAT ZOLTAN
IPC: H03G3/20
Filed: 1977-04-29
Abstract: The time constant control, for audio equipment with automatic gain control, increases the feedback time constant of the control loop to its greatest value (a few minutes) once the input signal has appeared. It is maintained at this value until a given delay time (1-5 sec) has elapsed. The time constant is then changed to a very short value (c. 1sec) provided that the output signal falls below a given reference level throughout the whole of the given delay time (due to a drop in input level). When the output falls below the given reference level the sensitivity of the AGC amplifier is increased again and the control loop's time constant is increased from its low value to its greatest value when the output is equal to a second reference voltage.

Title: Mixing and kneading machine e.g. for chocolate mfr. - with twisted revolving kneading bar moving past fixed bar loop
Inventor: MOELLER REINHOLD
IPC: B01F15/00
Filed: 1977-06-21
Abstract: A mixing and kneading machine consists of a vat and a mixing/kneading tool which is driven by a motor below the vat and supported in a conical rise of the bottom. The revolving tool has a complex shape and co-operates with a stationary tool which is fixed to the conical centre of the bottom. This results in such an intensive mixing/kneading action that a homogeneous mix is achieved in a much quicker time. The machine is equally suitable to liquid or powdery materials.

Multi-frequency code signals are sampled at a frequency of 8 KHz which is employed in many telephone exchange installations. The processing of the signals is done using quadrature correlation methods. If dial pulse signals are detected, the processor switches the clock generator to a lower rate.

Title: Automatic control of continuous casting speed in belt casting plant - using electronic control circuit with television camera monitoring casting front
Inventor: GROTH VOLKER
IPC: B22D11/20
Filed: 1978-07-12
Abstract: The cast prod. is metal plate or strip made in a mould formed by two travelling endless belts which are subjected to forced cooling. The casting front at the inlet to the gap between the two belts is continuously monitored by a television camera which is connected to an image monitor in which the image is employed as the parameter for the casting speed. A monitor feeds signals to a controller adjusting the speed of the casting machine. The casting front pref. has a position tolerance of 5-15 mm indicated by lines on the monitor screen. The image line function as a switch only altering the casting speed when the front wanders outside the permitted tolerance. A constant casting speed produces strip with a constant thickness and a uniform metallurgical structure over the length and width.

Abstract: The computer output microfilmer comprises a variable preset horizontal counter in which clock pulses generated in response to scan line synchronising signals are counted, and after a preset count value has been reached character formation is initiated. By incrementing or decrementing the presetting value of the counter, the character generation start point can thus be horizontally shifted by a desired amt. in either direction to thereby correct any data character-format line misalignment errors. A variable preset vertical counter is also provided, similarly fed by the scan line synchronising signals, to implement the correction of data character-formate line misalignment errors in the vertical direction.
