Title: A pulse width modulator
Inventor: MOLYNEUX-BERRY ROBERT BEWES
IPC: H03K7/08
Filed: 1981-08-14
Abstract: In a pulse width modulation amplifier comprising a pulse width encoder 2 followed by a filter 5 a problem arises when the average pulse duration changes substantially within the filter delay time. The risk of this is reduced by the present invention by a circuit 7 which has the effect of setting an upper limit to the rate of change or "slew rate" of the input signal. <IMAGE>

Title: Standing wave interferometer for measuring optical path differences
Inventor: BUCHNER HANS
IPC: G01N21/45
Filed: 1983-03-24
Abstract: The invention relates to a standing wave interferometer for measuring optical path differences in which a standing wave is produced between a monochromatic light source and a reflector. The displacement of the bulges and nodal points of the standing wave due to displacement of the reflector is sampled by a sampling normal inserted into the standing wave and having two photodetecting layers at a mutual space of kx lambda /8, k being any desired odd integer. The sampling signals are fed into an electronic evaluation unit where these are processed. The measuring object, when having a well-reflecting surface can be the reflector itself, without the necessity of adjusting the same accurately to the incident light beam.

Title: Improvements to print hammer mechanisms
Inventor: FARB NORMAN EDWIN
IPC: B41J9/127
Filed: 1983-07-27
Abstract: A print hammer mechanism for a dot matrix printer comprises a hammer element 16, magnetic circuit means operable to hold the hammer element 16 in a flexed retract position (Fig. 4) and an impact arrangement disposed opposite a portion of the hammer element 16 intermediate its ends. The hammer element 16 has opposite fixed 36 and free 38 ends and carries a printing element 40 adjacent its free end 38. The fixed end 36 of the hammer element 16 is secured to a magnetic element 58 forming part of the magnetic circuit means and a pole piece 46 terminates in a pole tip 48 facing the free end 38 of the hammer element 16.

Title: Dual rear circuit braking pressure control unit
Inventor: SCHOPPER BERND
IPC: B60T11/34
Filed: 1983-08-25
Abstract: A dual-circuit braking pressure control unit comprises in a valve housing (1), a pressure-proportioning valve (DM), connected in a first brake circuit (I), and having a by-pass passage (17) controlled by sleeve (18) and a co-axial pressure-limiting valve (DB), connected in a second brake circuit (II), arranged. The control piston (8) of the pressure-limiting valve (DB) projects into the outlet-side valve chamber (37) of the proportioning valve (DM) and thereby confines the pressure at the outlet (6) to the pressure prevailing at the outlet (5). Due to the arrangement of the valve seat ring (26) which is formed fast with the housing, the closure of the proportioning valve (DM) is independent of the position of the pressure-limiting valve (DB), as a result whereof a drop of the closure pressure of the proportioning (DM) in the event of a failure of the brake circuit (II), connected to the pressure-limiting valve (DB),will be avoided. On failure of the brake circuit (I) the sleeve (18) moves rightwards to open the by-pass passage (17). <IMAGE>

Patent GB-2168879-A (GB)
Title: Differential phase shift keying detector
Inventor: RUNNALLS JOHN JEMMISON
IPC: H04L27/227
Filed: 1984-11-19
Abstract: A differential phase shift keying detector comprises a high Q bandpass filter (W) which provides an output to a phase comparator (X) which includes a VCO. Phase comparator (X) compares the VCO frequency with the data carrier and produces a signal proportional to phase difference. A phase shift causes a decrease in the VCO frequency and the signal is supplied to a low pass filter (Y) where the waveform is adjusted and a reference voltage is used to provide switching levels for a pulse squarer and pulse stretcher. Advantages over known circuits include the use of much fewer components, high noise immunity and a simple setting up procedure. <IMAGE>
