Abstract: 1,257,967. Solid state polymerisation. SNIA VISCOSA SOC: NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 4 Feb., 1969 [26 March, 1968], No. 5907/69. Heading B1X. [Also in Divisions C3 and F4] Crystallised polyester pellets are simultaneously dried and solid-state polymerised by passing them continuously through a vessel 47 in countercurrent to a heated inert gas. Polyester which has been either pelletised and crystallised in a fluidised bed enters at the top of vessel 47 and falls as a bed under gravity, the pellets being removed at the base of the vessel by discharge rotary valve 58. The inert gas is first heated to a temperature of from 160 to 212C in heater 43 and then enters vessel 47 via plenum chamber 46, leaving via chamber 51. The gas velocity is kept below fluidization rates (below 2.1 ft/sec.). A level controller 50 is provided for controlling the residence time of the polymer in the vessel. The vessel should preferably have a height of at least six times its diameter and a cross-sectional area of at least twice that of the fluidised crystalliser used in the preceding step. Specified dimensions for the vessel are given in Examples 7-10.

Abstract: 1,258,020. Electromagnets. NATIONAL CASH REGISTER CO. 23 Sept., 1970 [6 Oct., 1969], No. 45246/70. Heading H1P. In a high speed printer, (Fig. 1) an impact hammer 28 is mounted on flexure springs 31 against cantilever stops 33 and a hammer penetration stop 44 and is actuated by an arm 17 of flat profile, with an impact face member 22 pivoted at 43 to the yoke 11 of double wound solenoid 13, 91 operating a massive armature 86. A positional backstop 24 and spring 19 control the arm movement and a return spring 29 of the hammer engages the underside of member 22. To reduce inertia and oscillatory stresses tending to fracture arm 17 and to reduce weight to enable high speed operation, the armature 86 is coupled to arm 17 by resilient material 88 (Fig. 2) interposed in a slot of the armature; the arm 17 being interposed between surrounding layers of the material (Fig. 2A not shown) through which operating forces are transmissible by shear. In fabrication, the opposed metal surfaces are roughened, degreased, and coated with a suitable cement after which the material 88 (which may be acrylonitrile butadiene rubber) is moulded to the metal members under heat and pressure, and heat cured. The windings are arranged to apply alternate N and S polarities to the armature to reduce flux in the yoke extension carrying the pivot, and in arm 17; and the reluctance of the flux path through arm 17 to armature 86 is reduced by conferring magnetic properties on the resilient material 88 by introducing particulate Fe 3 O 4 , Fe 2 O 3 , Fe dust or ferrite powder for dispersal by viscous rolling with a wetting agent. The resilient magnetic coupling is stated to be applicable to relays, E/M clutches and brakes, and magnetic transducers.

[Also in Division B3] A method of abrading or coating the surface of a workpiece comprises forming an enclosure with the surface as a wall thereof, applying suction to the enclosure, inducing the flow of primary air into the enclosure by the removal of air in the enclosure by suction while restricting the entry of secondary air from the surrounding atmosphere into the enclosure around the periphery of the surface, entraining a slurry comprising a mixture of abrasive and liquid or a coating material in the primary air prior to the latter entering the enclosure, directing the slurry or coating material entering the enclosure against the surface and entraining the spent slurry or excess coating material, if any, in the air being removed from the enclosure by suction. The method is a modification of that described in Parent Specification, the dry abrasive being replaced by the slurry or coating material. The method may be used in the apparatus described in Parent Specification or that described in Specification No. 1,247,701 for cleaning wire.

Abstract: 1337003 Testing corrosive resistant linings IMPERIAL CHEMICAL INDUSTRIES Ltd 19 April 1971 [19 March 1970] 13353/70 Heading G1N Damage or leakage in a corrosive resistant lining 2 of a multi-layer metal shell chemical reaction vessel 1 is detected by inserting a plurality of probes 4 in holes in the shell 1 and comparing the conductivity between each probe 4 and the shell 1 with a reference value. If the conductivity exceeds the reference value an alarm signal is activated. In one arrangement, Fig.2 (not shown), each probe has associated therewith a respective alarm signal device e.g. neon lamp and the probes are scanned continuously by a two pole mechanical selector coil one pole of which switches the selected input being scanned into a comparator whilst the other pole connects the output of the comparator to the corresponding neon indicator on a scanner panel. If the corrosive liquid leaks through the lining 2 the conductivity measured by the probe or probes at the point of leakage increases above the reference value and the respective neon indicator strikes and an audio alarm is sounded, the neon staying on until reset. In an alternative arrangement each probe is connected to a respective filter, the conductivity of the probe being represented by the voltage at the input to the filter. A high conductivity due to a leak appears as a low voltage whilst a broken cable appears as a high voltage. Two comparators compare the probe voltage with preset voltages respectively representing a high conductivity and a broken cable. If either fault condition occurs an alarm lamp for that probe is operated together with an alarm relay common to all the probes.

Abstract: 1339322 Analogue measurements MICRO CONSULTANTS Ltd 7 April 1972 [12 Jan 1971] 1489/71 Headings G1N and G1U [Also in Division H4] In an analogue transmission system in which a wanted signal 12 has an interference signal 13 e.g. 50 Hz hum superimposed thereon, the effects of the latter are eliminated by detecting 15 the zero-crossing instants of the interference, and, gating 10 the wanted signal to a receiver only during these instants. The receiver may be an analogue to digital convertor. A plurality of analogue signals may be multi-placed to a single receiver Figs.5, 6 (not shown). The pulse output of the gate may be stored and integrated prior to analysis in the receiver Figs. 11, 13, 14 (not shown). The zero crossing instants may be detected by using a separate interference source whose output is phase synchronised with that of the interference signal Fig.2 (not shown) or by filtering off a portion of the incoming signal Fig.4 (not shown) whereby the interference signal alone is presented to the zero crossing detector. The system is of utility in a remote measuring system wherein a physical variable e.g. temperature, pressure or weight, is monitored electrically and the wires over which the signals are transmitted to a central station are subjected to induced interference from adjacent power circuits.
