Abstract: 1,234,368. Refrigerators. INTEGRAL PROCESS SYSTEMS Inc. 13 March, 1970 [17 March, 1969], No. 12216/70. Heading F4H. In apparatus for freezing articles 24 which are conveyed through a heat-insulated chamber, at least a portion of the cryogenic liquid, e.g. nitrogen which is sprayed thereover from nozzles 39 is flashed to generate refrigerant gas which is recirculated by a fan 53 to the chamber to establish a flow of mixed fresh and returned gas in a portion of the chamber upstream of the spray section. The fan inlet 54 draws the gas from both the recirculating stream in the chamber above a baffle 50 below the conveyer and the freshly generated stream below the baffle and passes it through a plenum 52 whence it passes into the chamber either by deflection by a baffle 51 or through a passage 58 in the wall separating the plenum from the chamber. The gas flow through passage 58 is controlled by an adjustable baffle 59 actuated by a motor 62 controlled by a temperature responsive device 64 at the exit end of the chamber. An L-shaped gate controls the relative amounts of fresh and recirculated gas passing to the fan inlet 54 and means is described for feeding and regulating flow of liquid refrigerant to the nozzles.

[Also in Division B8] Continuous stationery, e.g. zig-zag folded webs divided into form lengths by fold lines and lines of perforations, is cut into lengths by feeding it through a cutting mechanism, and clamping it therein during cutting, said mechanism comprising a fixed carrier bar 10, Figs. 1 and 2, extending transversely of the web, and a cutting device 11 mounted on the bar for movement therealong. The web is fed over fixed anvils 21 and below clamping bars 22 having pegs 23 at each end passing through holes in the anvils and urged upwards by leaf springs 24, and having ramp portions 25 at each end. The device 11 comprises a carriage 13 embracing the bar 10 and mounting a shaft 19 which carries rollers 31 engaging the bar 10 and a pair of cutting discs 17. The discs engage the inner sides of the anvils and are separated by a resilient spacer 20, so as to be maintained at an angle on the shaft, being closer together adjacent the anvils. The carriage 13 also mounts two shafts carrying rollers 15 which when the device 11 is at rest near either end of the bar 10, have slight clearance from the bar. In operation the device 11 is moved, by poweroperated means or manually by a handle 16, along the bar 10, this movement bringing the rear rollers 15 against the bar 10, while rollers 18 also carried by the shaft 19 run on to the clamping bars 22 via the ramps 23, thus depressing the bars 22 against the force of the springs 24 to clamp the web 12. The rollers 18 running on the bars 22 rotate the discs 17 to cut-off a narrow transverse strip of the web, including the perforations. If there are no perforations, a single disc may be used.

The laser cavity is defined by two dielectric coated mirrors 12, 13. At the wavelength of the laser, 10,600 Š, the output mirror 13 has a reflectivity of about 50% and the mirror 12 has 100% reflectivity and is immersed in a saturatable dye solution cell 14 so as to produce mode locked pulses. The output from the laser is split in a beam splitter and each part is passed through a nickel sulphate attenuator cell to remove the peak power of the pulses. One part of the split laser beam is passed into a scanning unit and then focused by a lens into a spot which is scanned across an original pattern, e.g. a typescript or drawing. A detector picks up the reflected laser light and the output from the detector is used to modulate the other part of the split laser beam which is passed to a scanning unit and then focused by a lens into a spot which is scanned across a first material, e.g. carbon paper or ink-coated mylar which is evaporated on to an adjacent material, e.g. paper to build up a facsimile of the original pattern. Pressure sensitive paper may alternatively be used for building up the facsimile and the output of the laser may be monitored on an oscilloscope. The apparatus may be modified for three-dimensional, multicoloured or multi-material reproductions.
