Title: In-line colour TV CRT - allows colour adjustment by multipole coil system close on CRT neck generating homogeneous magnetic field for all three beams
Inventor: WITTIG CLAUS
IPC: H01J9/44
Filed: 1978-09-30
Abstract: In the adjustment process a magnetic device on the electron gun inside the tube neck is permanently magnetised by a coil system inserted on the neck. Since the deflection coil system is missing this magnetising coil system is tightly inserted and generated a homogeneous, vertical magnetic field common to all three electron beams which pases through the tube neck in the plane of the hard magnetic device at the electron gun. One of the three magnetic guns, preferably the middle one, and a saw-tooth, or triangular a.c. is passed through the multi-pole system in such manner that one electron beam marks on the screen a horizontal line of luminous spots. The line length is so chosen, as to contain all three screen phosphor colours. On to the a.c. is superimposed a d.c. of such magnitude that the middle gun colour appears in the line of extremely high purity.

Title: TV tuner control formed from single chip - has Zener diode and switching transistor biassed on or off for AM or FM demodulation
Inventor: CHRISTOPH SIEGFRIED
IPC: H03J5/02
Filed: 1978-11-09
Abstract: Digital storage is carried out by an integrated circuit chip for programme selection, frequency band change and fine tuning of a t.v. receiver. The store (1) containing the programme information provides an eight bit PCM code (at 2, e.g. 3, 4, 5, 6) which is decoded (7) and fed to an integrator stage (8, 9, 10, 11, 12, 13, 14, 34) to provide the switching conditions required for mono, stereo, near and distant station signal tuning. The output of the integrator unit (8 to 14) is also connected into a control which drives an antenna rotor so that the incoming signal can be accurately tuned. A further output from the integrated circuit (1) is fed to a ring counter circuit used for frequency band, station tuning and receiver fine tuning information and operation of the receiver. Another output provides a bias to a switching transistor to adjust for incoming a.m. or f.m. signals. The circuit uses a reference voltage from a Zener diode circuit connected to the collector of the switching transistor and the base connected to the circuit (1) control.

Title: Single-phase, low speed synchronous motor - has single axial excitation coil and shaded auxiliary poles
Inventor: MERKLE PAUL
IPC: H02K19/06
Filed: 1978-11-14
Abstract: The stator comprises two steel plates between which the excitation coil is located. The outer periphery of each plate is bent over into the axial direction and slotted to produce poles. The poles from the two plates lie in the same line and alternate. The rotor poles are similarly formed and lie radially inwards from the stator. Each stator pole is subdivided into two tips one forming a main and the other an auxiliary pole. The auxiliary poles are fitted with short circuited copper sleeves or rings to provide the necessary phase shift and give the shaded pole effect. The rotor teeth may be evenly spaced or may contain diametrically opposed sections with much larger tooth pitch.

IPC: G11B5/84
Filed: 1978-12-22
Abstract: The mfg. process is for a recording medium support for direct view images having light-sensitive and magnetisable recording surfaces. The latter surface consists of a foil permeated by magnetisable material. The foil is mounted on the side of the supporting material facing away from the light-sensitive surface. The supporting material is pref. made of paper. The foil is only made completely flat with the rear side of the support after the light-sensitive layer has been applied. Pref. this is carried out only after the support material is fully prepared, and the film web has been cut to the correct size of rolls. This procedure counteracts loosening iron oxide particles and dust particles tending to settle on the light sensitive surface during preparation with certain emulsions.

Title: Rotary chuck with indexing jaws - has compressed air passage with different flow resistances for various jaw positions
Inventor: REIPEN WILLI
IPC: B23B31/16
Filed: 1979-05-10
Abstract: The rotary chuck is particularly for lathes.

Title: Longitudinal flame cutting of continuously cast slabs - with simultaneous removal via hot gas stream of slag beards formed on cut edges of slab
Inventor: HENNECKE FRANZ
IPC: B22D11/126
Filed: 1979-07-04
Abstract: The slab or similar cast billet is placed on a wagon, which is driven underneath a stationary portal. On the horizontal top of the portal are one or more holders which can be adjusted transversely w.r.t. the longitudinal axis of the slab; and each holder carries a flame cutting burner. In a pit below the portal is a holder for one or more nozzles delivering a jet of thermal and/or kinetic energy which blows away the slag beard formed on the underside of the cut edges of the slab. The wagon platform pref. has one longitudinal slot aligned with each flame cutting burner, so the flames do not cut the wagon. Slag beards formed during conventional flame cutting are costly to remove. The invention eliminates such costs.

Title: Semiconductor light emitting diode - has insulated electrodes on opposite side of semiconductor body to that of light emission
Inventor: FENNER GUNTHER DR
IPC: H01L33/38
Filed: 1979-12-07
Abstract: The light emitting diode with a semiconductor body has an electrode is contact with the body on the same side as another electrode for contacting the pn junction zone. The body has an epitaxial layer of the same conductive type as the base layer of the semiconductor. The pn junction extends over a main surface of the semiconductor body or is on a mesa island on the semiconductor body. The light travels predominantly through the side of the semiconductor body which is remote from the electrode side. To prevent short circuits an insulation layer extends from one electrode to the other and covers part of the electrodes. Around the edge of the semiconductor body is a zone of opposite conductivity type so as to prevent solder applied to the electrodes from contacti-g the body around the edges.
