Patent DE-2715950-A1 (DE)
Inventor: BORN GOTTFRIED
IPC: D03D47/34
Filed: 1977-04-09
Abstract: The apparatus to be used on machines for the successive winding of flanged bobbins (2) with a specific thread length contains a rotating winder (3), a conveyor device working in steps for the flanged bobbins, and a retractable driver (9) on the winder. In order to prevent an uncontrolled thread run in front of the winder (3) during a bobbin change, a thread-retracting element (11) and a thread brake (12) are provided between the winder (3) and the supply bobbin (10). To prevent overhead draw-off from the flanged bobbin (2) by the thread-retracting element, the flanged bobbin (2) is assigned a controlled insertion element (13) which can be inserted into the winding space of the flanged bobbin (2) during the retraction of the driver (9). The apparatus is used preferably for the winding of flanged bobbins which are used in shuttles of wave-shed weaving machines. <IMAGE>

Title: Ceramic bodies of increases breaking strength - consisting of two different zirconia and alumina phases
Inventor: CLAUSSEN NILS DR
IPC: B32B18/00
Filed: 1977-04-18
Abstract: Ceramic body consists of a matrix and >=1 dispersed ceramic phase of increased ultimate extension. Both the matrix and disperse phase consist of alumina and unstabilised ZrO2 particles, the dispersed phase contg. 3 vol.% more ZrO2 than the matrix. Pref the matrix contains 9-17 vol.% and the disperse phase 12-20 vol.% ZrO2. The body is used for ductile high temp. gas turbine elements. The disperse phase exists in different enantiotropic solid modifications at room temp. and at the firing temp. Due to the differences in density of the 2 forms there is a high concn. of very fine microcracks throughout the body. The fracture energy of the composite body is much greater than that of either of the component materials.

Title: TDM data transmission receiver - avoids effect of temp. drift on length of bits in start combination
Inventor: FUHRMANN HANS DIPL ING
IPC: H04L7/04
Filed: 1977-04-27
Abstract: To avoid the effect of temperature drift in the transmission channel on the length of the bits in a start combination, synchronising of the pulse telegram is effected in the middle of the 'L' phase of the start combination. From the beginning of the start combination pulses from a generator (1) are fed via a frequency divider (2) which halves the frequency to a counter (4). On correct identification of the 'L' phase of the start combination up to the end of the pulse telegram, pulses from the generator (1) of frequency fo are fed to the counter (4). The counting state of this counter is compared in a logical circuit (7) with a counting state stored from the middle of the 'L' phase of the start combination to the middle of the bit following the start combination.

Title: Picture tube beam current suppression circuit - applies constant voltage to blanking circuit making it operative when beam blanking pulses fail
Inventor: DETTMANN PETER DIPL ING
IPC: H04N3/20
Filed: 1977-05-26
Abstract: The picture tube beam current is suppressed when parts of the equipment surrounding the tube fail. The circuit has a circuit controlled by blanking pulses which blanks the electron beams during a period of the electron beam cycle not used for display. Blanking pulses are so coupled with a constant voltage (Usp). that when the blanking pulses fail, the voltage (Usp) is applied to the blanking circuit (11) input and makes it operative. The pulses are fed to the blanking circuit over a clamping circuit including a diode, capacitor, and two resistors, which is connected to the voltage source.
Patent DE-2724448-A1 (DE)
Inventor: MAUTHE GERHARD
IPC: H01H3/40
Filed: 1977-05-31
Abstract: In an electrical switching device with an axial, reciprocally mobile contact piece, to convert the rotary motion of the switch drive at minimum cost and with a minimum of moving parts into reciprocal motion of the mobile contact piece (31), the axial, reciprocally mobile contact piece is mechanically coupled to the rotary drive (23) via a rotary gear (21, 22), preferably a planetary gear. The omission of cross-stressed gear slideways which is thus made possible, with the associated reduction of friction losses, ensures that the drive is highly efficient. The drive rotates through 180<o> at each switch stroke, and the rotating crankshaft of the drive rotates in the same direction during both in and out switch strokes. Since the switch stroke depends essentially on the size of the sun wheel (21) of the gear, the height of the switching device is minimised. Also, relatively imprecise positioning of the drive (23), particularly when the switching device is powered up or down, has a negligible effect on the position of the contact piece (31). <IMAGE>

Title: Automatic water sprinkler system for coal conveyor - has fusible plug to start water spray and float valve to stop it after preset delay for fire protection
Inventor: BONNEL MICHEL GEORGES GASTON
IPC: A62C37/38
Filed: 1978-03-18
Abstract: The fire sprinkler system is fitted to a coal conveyor and is initiated automatically. The water spray (7) is also stopped automatically after a preset delay. The water supply (1) passes through a differential pressure valve (2), a bypass (18) to the larger side (12) holding it closed. When a fusible plug (6) in this bypass melts, the pressure reduces and the valve opens to supply the nozzles. A bleed (10) commences to fill a tank (4) surrounding the system, the water level rising to operate a float valve (3, 5) in the bypass and cut off the flow. The pressure increases to also close the differential pressure valve.

Patent DE-2827418-A1 (DE)
Inventor: HECHT SIEGFRIED DIPL ING
IPC: G08C19/28
Filed: 1978-06-22
Abstract: In the case of information of a plurality of process systems (4) which is retrieved in time division multiplex, transmission to a central station (1) normally takes place with standardised telegrams which, as a result of strict compliance with the prescribed occupancy plan, results in incomplete utilisation of system transmission capacity or an increase in the time required for transmission. The problem is solved by compressing the standardised telegrams prior to their serial transmission from each individual process system (4) to the central station (1) in an operation component (5) of the process system (4) concerned and by correspondingly converse expansion following transmission in an operation component (3) of the central station (1). During the compression, the blank characters of the telegram produced by the standardisation are omitted without adversely affecting the information content, the sequence also being retained. The blank characters are added once more in the central station according to the standardisation in a reversibly unambiguous manner. <IMAGE>
