Filed: 1971-12-09
Abstract: 1360286 Furfural (furfurole) WINTERSHALL AG 9 Dec 1971 57356/71 Heading C2C The formation of solid residues during the heat treatment of furfural or furfural-extract mixtures (obtained by solvent extraction of raw material with furfural) is prevented by passing part or all of the latter, exposed in an apparatus to a temperature of 120-220‹ C., through a layer of porous, coarse-grained (3 to 10 cm. diameter) gas coke, which acts as a crystallizer for the residue-forming materials, the load being 0À1-10 volumes per hour of furfural or furfural-extract mixture per volume of the gas coke and subsequently returning the so-treated furfural or furfural-extract mixture to the apparatus. In a preferred operation a partial flow of 5-20% by volume of the furfural or mixture, which is exposed to a temperature of 120-220‹ C., is continuously drawn off and after passing through the porous gas coke layer, is returned to the apparatus.

Title: Manlfunction monitoring equipment in a time division multi plexed transmission system
IPC: H04B17/00
Filed: 1970-12-15
Abstract: 1326926 Testing pulse-code modulation systems NIPPON ELECTRIC CO Ltd 15 Dec 1970 [16 Dec 1969] 59564/70 Heading H4L An arrangement for monitoring for malfunctions of a time-division multiplex PCM communication system, for example malfunction of the coder or decoder, utilizes one of the channels for transmission of coded noise, this channel being demodulated at the receiver to provide a power indication. In one embodiment white noise is band-limited to 2-4 KHz before coding and the quantizing and other noise generated below 2KHz in this channel is filtered at the receiver to give the required indication (Fig. 3, not shown), or in a modification the so-filtered noise power is compared with the 2-4 KHz power to give an indication of signal/noise ratio. It is stated that relatively low noise powers are adequate to give a reliable function/malfunction indication, thus reducing the crosstalk degradation of signal channels.

Title: Improvements relating to lasers
Inventor: DYSON DAVID JOHN
IPC: G01J1/42
Filed: 1969-12-12
Abstract: 1,268,407. Lasers. FERRANTI Ltd. 6 Nov., 1970 [12 Dec., 1969], No. 60657/69. Heading H1C. The partially transmissive output mirror 10 of a laser provides both a main output beam 14 and a focused secondary output beam 15, each output extending along a different path. The main output beam comprises the major portion of the generated power, the secondary output being obtained by reflection between the non- parallel major surfaces 11, 13 of the mirror and used for monitoring purposes, e.g. by a detector located at the focal point 16. The distance of the focal point from the mirror may be reduced by using a concave reflector 17. The non-parallel major surfaces 11, 13 of the mirror may be either concave, as shown, or planar, the surface 11 being normal to the optical axis 12 of the laser, while the surface 13 has its centre of curvature (or normal in the planar case) on a line which intersects the optical axis at the surface 11 by a small angle such as 4 degrees. The power of the secondary beam is determined by the relative reflectivities of the two surfaces 11, 13. For a carbon dioxide laser the mirror may be formed of germanium.
Patent GB-2001486-A (GB)
Title: Improvements in rectifiers
IPC: H02M7/08
Filed: 1978-06-09
Abstract: A rectifier unit for 3-phase a.c. to d.c. conversion is of the type having a transformer (10) with a star-connected secondary (14) and a delta-connected secondary (16) the outputs of which are respectively rectified by rectifier bridges (18, 20) and combined to give 12- pulse operation. To reduce the danger of current imbalance between the two secondaries, a compensating transformer unit (30) is interposed between the secondaries (14, 16) and the rectifiers (18, 20) which modifies the signals from the secondaries such that any difference in the current drawn from one secondary compared with the other tends to equalise the current drawn from the secondaries. The compensating transformer unit can take the form of 3 individual transformer units but is preferably a single transformer with 3 limbs, each of which carries a main winding (32) connected to one secondary and two opposed subsidiary windings (34, 36) which receive the phases from the other secondary which are closest to and on either side of the phase of the associated main winding. The compensating arrangement may be generalised for systems with more than 3 phases. <IMAGE>

Patent GB-2002928-A (GB)
Title: Toner concentration monitoring
IPC: G03G15/08
Filed: 1978-07-31
Abstract: The invention relates to the controlling of the concentration of toner in electrographic developer mixtures, wherein toner concentration is determined by sensing the reflectivity of the developer mixture. An electrographic developer mixture contains toner particles and carrier particles. During use, a proportion of the toner particles become non- transferably attached to the carrier particles, a phenomenon known as scumming, and hence the reflectivity of the mixture is not a true indication of the concentration of toner particles available for transfer to an electrostatic image. The signal produced by measuring the reflectivity of the mixture is modified in dependence upon the expected extent of such scumming, the expected extent of scumming being derived from the usage of a copier in which the developer mixture is employed, for example, from the number of copy making operations carried out by the copier. <IMAGE>

Title: Brake control valves
IPC: B60T8/28
Filed: 1978-10-12
Abstract: An inertia-controlled valve unit for limiting the pressure rise in the rear wheel circuit of a vehicle hydraulic braking system is by-passed when the front wheel circuit fails, so as to give full braking pressure in the rear wheel circuit. The valve unit has an outlet 34 connected to the rear wheel brakes, and an inertia-controlled valve 3, which closes when the deceleration of the vehicle is excessive, to ensure by means of a metering valve 20 that any subsequent increase in pressure applied at the outlet 34 occurs at a rate less than the rate at which the master cylinder pressure increases. The unit also incorporates an override means 13 responsive to front wheel brake pressure which is operative, following closure of the inertia-controlled valve 3 and reduction in front wheel brake pressure, to override the effect of the inertia-controlled valve 3. <IMAGE>

The bottom of the vessel is trough-shaped and inclines downwardly to a liquid outlet from which liquid having entrained therein foreign particles is removed from the vessel. At least one of the air pipes is positioned to terminate adjacent the liquid outlet and to emit air which agitates any foreign particles tending to settle on the bottom of the vessel adjacent the liquid outlet.
