[Also in Division B8] In a guide housing for air entraining dust or fibres and of the kind in which the air moves in a vortex and is discharged with the dust or fibres through a tangential outflow passage, the passage extends in a direction opposed to that of the vortex. As shown in Figs. 1 and 2, a vortex separator comprises a housing 12 having at its top a vortex-generating volute 14 for the inflow of dust or fibre-contaminated air. The major portion of the air is discharged through a filter 20 and a clean air tangential outlet pipe 16.

Fans 19, 21 are mounted in the pipes 16, 26. In a modification, Figures 3 and 4 (not shown) the contaminated air enters the housing axially through vortex-producing vanes and the clean air is dsicharged through an axial outlet surmounted by a conically-shaped filter and extending centrally through the spiral-shaped guide housing.

Abstract: 1,232,850. Testing reflective properties of a chamber by sound and radio waves. DEVENCO Inc. 24 July 1968, No. 35298/68. Heading H4D To provide a visual representation of the reflective properties of a chamber a coherent sound or microwave field is produced in the chamber, the reflections are sensed at points in a plane to give corresponding signals, a reference signal coherent with the source is added to the corresponding signals, the ensuing signals are recorded optically, and the record is illuminated by a source of coherent visible light. Utilizing sound waves, Fig. 2.-A set of microphones 15 in a plane 16 near to the front row of seats in a concert hall having a coherent sound transmitter on the stage produces signals which are frequency-translated to different portions of the spectrum and thereafter fed to magnetic recorder 20; the playback from the recorder is frequency translated back to baseband signals which are fed to mixers 28 fed also with coherent oscillations from oscillator 29 via phase shifters 32. The mixer outputs intensity-modulate a cathode-ray tube 33 which is photographed to give a hologram.  Utilizing radio waves, Fig. 3.-The reflections which can occur in a bi-static anechoic chamber 37 (used for testing aerials) are obtained by a microwave transmitter 39, a receiving aerial 46 scanning horizontally and vertically, a cathoderay tube 53, a mixer 50 and phase-shifter 51.

Abstract: 1,234,544. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. 1 Oct., 1969 [1 Oct., 1968], "So. 48316/69. .Heading.HIK. A'semi-conductor device is produced by forming a:region of.one conductivity type extending to one face of semi-conductor wafer, forming a multi-apertured masking layer thereon, placing a foil of alloying material over the mask -and directing an electron -beam so as to alloy it to the region within the .apertures to --form regions of the opposite type connected together by the remainder of the foil. In an application to forming a PNP silicon transistor the base zone is formed by predeposition of arsenic or antimony over a conventionally apertured silicon oxide, dioxide or nitride layer followed by diffusion. After reforming the masking layer a number of apertures are formed therein by conventional steps, or preferably by electron beam erosion, in which case the process may be continued to form shallow pits in the silicon. Then a 25-50 Á foil of gold-boron alloy is located in registry over the base region and an electron beam, preferably controlled in its movements, intensity and cross-section by a programmed computer, used to effect the alloying of the emitter regions. Base contacts are formed before or after this step by masked vapour deposition into apertures in the insulation. Alternative materials are specified for use in forming PNP germanium and NPN silicon transistors.

A steel substrate is coated with a metal e.g. Zn, Al, Ti, Cd, Cr, Ni or stainless steel by vapour deposition, whilst maintaining the substrate at 200‹C. The substrate is first chemically cleaned then subjected to a glow discharge for 1 to 30 seconds. The coating metal may be heated by induction or electron beam. The substrate may be in the form of a strip continuously drawn through several chambers. The coated strip may be given a further coating of Al.

Abstract: 1,257,331. Nuclear magnetic resonance spectrometers. NEWPORT INSTRUMENTS Ltd. March 11, 1969 [March 11, 1968], No.11806/68. Addition to 1,125, 481. Heading G1N. In a nuclear magnetic resonance spectrometer for measuring the moisture content of materials, the sample 12 under test is repeatedly scanned through resonance and a gating circuit 24 is controlled to pass only signals occuring during a small range of each scan cycle centered on the proton resonance line of unbound (i.e. liquid) molecules and having a bandwidth much narrower than that of protons in molecules which are bound in the solid state, which signals are integrated at 28 over a large number of scan cycles. Initial setting up is done by adjusting a reference oscillator 42 to zero beat with the r.f. oscillator 20, using a sample 12 providing a strong output; the oscillator 42 is then used as a reference for adjusting the oscillator 20 when samples having weak output signals are under test. The r.f. level should be as high as possible without saturating the sample, and a paramagnetic relaxing agent may be added to the sample to raise the saturation level. The temperature of the sample is preferably controlled. Timing and command circuits 34, 36, 38 control the integrating time of integrator 28 and trigger the voltmeter 32 and provide both single-shot and continuous modes of operation.

Abstract: 1,258,476. Sensing coded records. HUGHES AIRCRAFT CO. 18 March, 1969 [27 March, 1968], No. 14147/69. Heading G4M. [Also in Division G1] Coded marks (printed or fluorescent) are sensed by scanning them with a beam of light or by scanning an image of the marks across a photodetector, the scanning taking place in a plurality of different directions to allow for mis-orientation between the marks and the sensing station. In the apparatus shown, a wide beam 11 is produced by a lamp 10 and slit 14, a linear scan is imparted to beam 11 by a rotating mirror drum 16 (the linear scan direction need not be at 90 degrees to the beam width), and the direction of successive scans is angularly displaced by rotating mirrors 24, 26, 28 or a prism. Mirror drum 16 may be replaced by a single oscillating mirror so that successive scans are made in almost opposite directions. The code marks may be wide and narrow bars which may be symmetrically arranged for scanning in either direction, or which may form concentric triangles. Photodetector 38 has a threshold such that it only responds when the beam 11 is approximately aligned with the code bars. In another embodiment, Fig. 6 (not shown), the optical system is used in the reverse sense to scan light reflected from an illuminated code area across a photodetector which is placed at the position occupied by source 10 in Fig. 1. In yet another embodiment, Fig. 7 (not shown), a beam splitter is placed between source 10 and mirror drum 16, light from source 10 being projected forward through the optical system to the coded area as in Fig. 1, and reflected light travelling through the system in the reverse direction until the beam splitter directs it towards the photodetector.
