Title: Gas-fired infra-red burner
IPC: F23C99/00
Filed: 1971-11-26
Abstract: 1367923 Infra - red gas burner RAI RICERCHE ED APPLICAZIONI INDUSTRIALI SpA 26 Nov 1971 [26 Nov 1970] 55082/71 Heading F4T In a gas-fired infra-red burner including a first non-porous generally flat reflector 40 and a second non-porous generally curved reflector 70 having a concave surface facing the first reflector 40, a combustible fuel gas mixture is directed to impinge on the concave surface of reflector 70 and be reflected to impinge on reflector 40. The fuel gas mixture passes from a conduit 20 through a sleeve 30 and orifice 32 to a plenum chamber 14, defined by an outer casing 10 and an inner casing 12, in which a deflector 80 circulates the mixture. The mixture then passes through a median longitudinal opening (18), Fig. 5 (not shown), in the inner casing 12 and first reflector 40, and is ignited by an electric arc between a central electrode 90 and the reflector 40. After reflection from reflector 70 and then reflector 40, the combustion products exit through flue openings 82 between reflector 40 and the side walls of the burner. The first reflector 40 is insulated from the inner casing 12 by layers 58, 60 of ceramic fibre. The reflectors 40 and 70 are of a nickel-chrome alloy and are mounted on rods 42, 44 and 72 which permit sliding thereon of the reflectors during thermal expansion. An electronic system including the electrode 90 may be used to monitor the presence of a flame.

Abstract: 1293161 Photo-sensitive materials KALLE AG 11 Nov 1969 [9 Dec 1968] 55103/69 Heading G2C [Also in Division B6] A photosensitive material for the production of continuous tone printing plates comprises a support coated with a light-sensitive layer (preferably containing a naphtho- or imino-quinone diazide or an azide) with hollows, the distance of the centre of one hollow to the next not exceeding the sum of the two diameters of adjacent hollows, the hollows having diameters from 1-50 microns (distances and diameters being measured at the outer surface of the layer) and the hollows decreasing with approach to the support. The hollows are produced by (i) incorporating in the layer particles of a substance which is insoluble in the coating solvent but at least partly soluble in a solvent in which the layer is insoluble and removing the particles by treating with the second solvent, e.g. crater-soluble sodium chloride particles or polyvinyl alcohol spheres in a water insoluble layer or (ii) embossing the control layer with a layer of brushed aluminium or glass balls of the desired diameter. Materials containing the hollows in the layer produces more steps when exposed to a step wedge than a smooth layer.

Abstract: 1,091,309. Determining length by radar means. COMPAGNIE D'ETUDES ET DE REALISATIONS DE CYBERNETIQUE INDUSTRIELLE. Dec. 30, 1965 [Jan. 8, 1965], No. 55208/65. Heading H4D. A C.W. Doppler radar 5 illuminates a product 2 travelling in the direction 13 on a rolling mill train 1, by means of a beam 6. The Doppler beat pulses are fed to a counter 10, which starts to count when the leading edge of the product interrupts the radio path between transmitter 8 and receiver 7, and terminates the count, when the trailing edge of the product clears the path between transmitter 12 and receiver 11. With suitable correction the count on 10 indicates the length of the product. The distance between the two radio paths must be added to the count at 10. The two radio paths may be replaced by corresponding optical paths produced by a light source illuminating a photo-electric device. The count may also be used to indicate the velocity of the product.

Title: Television system

Abstract: 1337727 Television NIPPON HOSO KYOKAI and MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 24 Nov 1970 [27 Nov 1969 28 Nov 1969] 55934/70 Heading H4F In a system for converting a facsimile signal into a television signal for transmission via an aerial 412 the facsimile signal is passed to a separator 401 which separates the synchronizing signal from the picture element signal, Fig. 6(a). The picture element signal is sampled and pulsewidth modulated, Fig. 6(b), and this signal is fed to an AND gate (10, Fig. 5a, not shown) fed with pulses supplied by a pulse-number multiplier from a clock pulse generator 406, there being 256 pulses for each sampling period. The resulting output, Fig. 6(c), is passed to a binary counter, the output from which is fed to a buffer memory 402. When the signals corresponding to one line of the facsimile signal, 400 msec., are stored in the buffer memory 402 they are read out in the time corresponding to one line of the television signal, 63À5 Ásec., Fig. 6(d), and passed via a delay line control to delay line 404. The signals in the delay line 404 are delayed for <SP>1</SP>/ 60  sec., i.e. one television field, and are then read out and fed back into the delay line 404. When a second line of facsimile signal has been stored in the buffer memory 402, this is read out at such a time that it is fed into delay line 404 one television line, 63À5 Ásec., behind the preceding line. This is continued until 262À5 lines of signal are stored in the delay line 404, after which these signals are read out and passed via level adjustment 407 and recorder 410 to aerial 412 for transmission. When sequential colour facsimile signals are received, delay line 404 includes three delay lines, one for each colour, red, green, blue, a signal being fed to the delay line control 403 which controls the colour sequence, an NTSC (or PAL or S.E.C.A.M.) converter 409 being included. To reduce the size of the buffer memory 402 required, a second delay line control (703<SP>1</SP>, Fig. 7, not shown) and delay line (704<SP>11</SP>) (or three delay lines for colour operation) similar to control 403 and delay line 404 may be introduced between the buffer memory 402 and delay line control 403, buffer memory 402 storing less than one line of facsimile signal, the second delay line (704<SP>11</SP>) building up a television line at a time, which television lines are then passed to delay line 404, and a television field is built-up as before. The delay line 404 may be replaced by a video disc recorder (Figs. 8, 9, not shown) which builds up the television fields and which may carry synchronizing marks round its circumference to control the read out of the signals stored in the buffer memory 402. For colour operation the video disc has three tracks.

A carriage 70 having suction cups 72 to grip the central panel of a first blank pulls the first blank and goods downwardly into a bucket 90 while stationary folding members (64-68) fold the side panels upwardly and the flanges on the sides of the blank inwardly. The bucket comprises four adjustable corner members (91-94) which hold the first blank folded and have abutment strips (98) to locate the folded flanges. As the bucket is moved along guide rails 101, bars 111 (112) fold the flanges on the top of the side panels downwardly while edges of plates 115 (116) engage the inner surfaces of the fold lines between the flanges and the panels. The second blank drops from a magazine and is fed by a tined pusher (41) on guide rails 131, 132 to beneath hold down bars 211, 212 on an elevator 150. The bucket moves beneath the second blank and the elevator 150 lifts the loaded and folded first blank against the second blank. As the second blank is raised rods 141- 143 fold the side panels downwardly, the guide rails 131, 132 being partially cut away to permit this. The folded package is then pushed by bars 225, 226 into a compression chamber composed of top rods and of side rods forming continuations of the rods 141-143, to secure the margin of the second blank to the flanges of the first blank by adhesive previously applied or applied by applicators (42-48) in the machine to the first or second blank.
