Title: Mixing control for multi-channel magnetic tape recording - has signal which senses recording section to open gate to activate playback head output to mixing unit
Inventor: PAULER GUENTER
IPC: G11B27/36
Filed: 1975-04-29
Abstract: A mixing control unit for multichannel tape recording systems avoids the reproduction of background noise when tapes are mixed. If two tapes are being mixed it is necessary to avoid the reproduction of blank sections during a pause. The tape unit has a recording head that is slightly ahead of the playback head and consequently a signal may be derived to gate the playback head output. The recording head output (1) is passed over an equalising stage (2) to a rectifier (3) to generate a gating signal for a fast response switch (4) controlling the transmission of the playback head (5) to the mixing control (7). As soon as a section of actual recording appears on the tape the recording head senses the signal ahead of the playback head and opens the gate (4).

Title: Damping weight step motor - is made of tool steel for strong hysteresis producing field lagging rotor field
Inventor: SUDLER ROLAND
IPC: G04C3/16
Filed: 1975-06-18
Abstract: The damping device is for eliminating oscillations at the natural frequency of a stepping motor rotor. A multipolar permanent stepping motor rotor. A multipolar permanent magnet, radially magnetised, is fixed to an aluminium disc (3) with a central hole (4). The motor shaft (1) passes through the centre of this hole, and an inertia mass (6) (which provides the damping) is borne on the shaft on a bush (7) of synthetic material. The inertia mass is made of tool steel which exhibits marked hysteresis, but comparatively small coercive force. There is a small air gap between mass (6) and rotor (2). When the rotor is started from rest, the magnetic field developed strongly in the inertia mass follows that of the rotor with a time-lag due to the hysteresis effect. At the end of each step, the lag causes braking and hence damping of the rotor.

Title: Systems camera with matched viewfinder - has pivotable mirror frame giving optical warning signal when end positions not fully enlarged by selected lens
Inventor: SIMON HORST
IPC: G03B13/12

Title: Thrust control for VTOL aircraft - with part of airstream diverted to rotors inside wings to alter lift without changing pitch
IPC: B64D27/18
Filed: 1976-02-10
Abstract: The VTOL aircraft has gas turbine power units in its delta wings with the compressor stage of each engine larger than normal. Part of the compressed airstream is tapped off and led to rotors inside the wing profile where they feed combustion chambers in the ends of the rotor blades. For cruising, the tapped air is fed to the wings where it is expelled via special slots over the rear end of the top surface. This generates improved lift. The exhaust gasses can be fed into the rotor blades, through ducts, to alter the lift characteristics of the blades without having to alter the blade pitch.

Title: Composite audio magnetic tape heads - are for mono and stereo tapes and include erase facilities
Inventor: SHIMODA MISAO
IPC: G11B5/187
Filed: 1976-05-26
Abstract: Writing and erasing heads for mono and stereo tapes usually have magnetic poles for writing, separated by a narrow gap and another erase pole separated from the write head by a broader gap. The new design avoid some of the problems associated with the manufacture of composite heads. They have a section cut from a roughly U-shaped unit the two legs of which (101a, 102a) are of magnetic material and are separated at the base by a suitable resin filled gap (103a). Layers of non magnetic material (104a, 105a) surround this arrangement before the section is cut. An erase facility can be included by incorporating a third section between the two existing elements again with suitable gaps. In this case one of the legs is reduced in thickness so that the read-write track is narrower than the erase track.
Patent DE-2623989-A1 (DE)
Title: Monomode fibre optical light guide - with equal phosphorus oxide content in core and sheath and boron oxide in sheath
Inventor: VOLLMER HANS-PETER DR PHIL
IPC: G02B6/02
Filed: 1976-05-28
Abstract: A dielectric monomide optical light guide is made of quartz glass with varying dopant contents in the core and sheath areas. Both these areas include a first dopant, which increases the refractive index, in equal proportions. The sheath area contains, in addn. a dopant which reduces the refractive index. This prevent a flattening of the step in the refractive index between core and sheath which would result in a very great attenuation of the monomode light transmission. The light guide is ideal for a broadband transmission of optical signals.
