Title: Image reproduction systems
IPC: H04N1/405
Filed: 1974-01-30
Abstract: 1495499 Facsimile system CROSFIELD ELECTRONICS Ltd 24 Jan 1975 [30 Jan 1974]04250/74 Heading H4F A facsimile system includes apparatus Fig. 13 for controlling the illumination of light sources, in a scan head 54b, which when all energized, cast a line of light across a scan line of a light sensitive copy medium. The apparatus includes two pairs of shift register devices each device comprising a pair of shift registers (i.e. eight shift registers 58). The shift registers have bit locations in 1:1 correspondence with the light sources. Alternate trains of onerepresenting and zero-representing pulses are shifted through the registers with a 1:1 mark space ratio. Fig. 14 illustrates the logic circuit for controlling the illumination of the light sources in response to the content of the respective bit location in each of the light registers 1a to 4b. The registers are grouped in pairs (e.g. 1a and 1b) forming devices. The bit streams in each device move in the same direction but with a variable phase difference between its constituent registers. Corresponding bit locations in each register pair have their contents exclusively OR'ed, 61, to produce the device outputs. By altering the relative phase (in accordance with the video signal) of the bit stream in the second, b, register of any pair, a different mark space ratio for the respective device is obtained. The outputs from any one device are AND'ed, 62, with those of another device wherein the bit streams move in opposite direction as indicated by the arrows in Figure 14. Two pairs of devices are necessary in order that one may operate to cover the areas missed by the other. The output of the AND stages of each pair of devices are OR'ed, 63, to control the on/off state of the light sources. Differing screen angles are obtained by varying the bit stream flow rates between devices. The shift registers may comprise more bit location than there are light sources so that each light source may be provided with a plurality of outputs for enabling a plurality of energization levels Fig. 16 (not shown). Figs. 1 to 12 (not shown) illustrate bit stream structures and movement along with the consequentially derived variations in half tone dot structure. A circuit in which a picture signal is used to adjust the phase of bit streams and thereby the length of a train of ernegization control signals emanating from the shift register device is described w.r.t.. Fig. 15 (not shown). One such circuit suffices for all the left shifting registers and another is employed for the right shifting registers. The shift registers may be "circular".

Title: Improvements relating to the processing of materials
IPC: B02C19/18
Filed: 1955-02-14
Abstract: 799,578. Grinding. LECHER, J. Feb. 14, 1956 [Feb. 14, 1955], No. 4330/55. Class 59 Apparatus for reducing the size of particles comprises means for introducing the particles into an upwardly-flowing stream of fluid in a casing 1, means in the casing for establishing "intense sonic energy" in the fluid so as to disintegrate the particles, and means for separating the upwardlyflowing stream into two streams, the inner of which contains the particles of smaller size; the expression "intense sonic energy" is defined as an energy comprising a range of frequencies which extend from a minimum corresponding to the lower audible up to and including the ultrasonic and has an energy level in excess of 120 degrees (as compared with a datum of 0.000204 dyns. per sq. cm.). The material to be reduced is discharged in a gaseous or liquid carrier or a liquid having an entrained gas down a fixed central tube 4 in the casing on to a rotating plate 6 so that it is thrown radially outwardly into the path of gas or air which is drawn into the casing through openings 11 in the casing discharged upwardly around the periphery of the rotating plate 6 by fan blades 10 on the shaft 7 of the plate; vanes 18, 18a on the plate 6 facilitate the outward discharge of the particles. In its upward path, the fluid particle-containing stream encounters annular discs 15 mounted on radial blades 14 carried by rings 12 from a sleeve 3 which rotates on the tube 4 with the plate 6 by reason of its connection with the vanes 18. The discs 15 are connected between adjacent sets of blades 14 by bolts 15a so that they can vibrate freely, and both the blades and the discs 15 are made of such material and thickness that the high speed upward flow of the liquid causes them to vibrate to produce the intense sonic energy which, together with the collisions between the particles results in the desired disintegration. The upwardly-flowing fluid stream is divided into inner and outer concentric streams by bending the upper and lower inner corners of the blades 14 respectively backwardly and forwardly in relation to the direction of rotation, as shown in Fig. 3; the smaller particles pass from the outer stream into the inner stream and are led away through the outlet 21, and the larger particles pass upwardly in the outer stream and are led out of the casing near the top into a bleed pipe 22 which reintroduces them into the casing at the periphery of the plate 6. In an alternative form, this subdivision of the stream is effected by providing the sleeve 3 with impellers of suitable aerodynamic shape instead of, or additionally to, the bending of the corners of the blades 14. Specification 696,799 [Group III] is referred to.
Patent GB-396811-A (GB)
Title: Improvements in or relating to picture transmission systems
IPC: H04N1/00
Filed: 1932-02-13
Abstract: 396,811. Copying-telegraphy. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Feb. 13, 1932, No. 4361. Convention date, Feb. 28, 1931. [Classes 40 (iii) and 40 (v).] In a photo-telegraphic or like system for transmitting pictures &c. of the kind in which the transmission is keyed or intermittently interrupted in accordance with the picture signals, in order to compensate at the receiver for variations in the general intensity of the signals by fading or like interference, the degree of amplification of the receiver is automatically adjusted at predetermined time intervals in accordance with the intensity of the incoming signals without the use of a special carrier frequency for the purpose. ' In a convenient arrangement a signal of constant strength is sent out by the transmitter once in each revolution of the picture drum and at the time of receipt of this signal at the receiver a special circuit is closed for a short interval, automatically adjusting the grid bias of one of the valves, preferably at the high frequency stage, and thereby regulating the amplification for the succeeding revolution of the drum. In the receiver shown, signals picked up by the aerial An pass to the detector A through the high-frequency amplifier H, and thence to a plurality of valves represented by L1, L2 working in parallel. In the anode circuit of the valve L2 is included the filament F of a string galvanometer to regulate the light falling on the receiving drum B from source L, while in the output circuit of the valve L1 is arranged a resistance W, the voltage across which varies with the intensity of the signal and is adapted periodically to charge a condenser C, which in turn, by connection through choke Dr and inductance Sp, controls the grid bias of the first high - frequency valve H. The circuit between the resistance W and condenser C is completed periodically via brush B2, slip ring R and disc K0 on the drum shaft and brush B1, the disc K0 having a contact K which rests on the brush B1 for the short interval during which, at the transmitter, the white edge of the picture or a painted clamp bar Sch is being scanned and a signal of constant. intensity is being sent out. The charge applied to the condenser C is thus determined at the commencement of each revolution of the drum according to the received strength of the " feeler " signal and regulates the amplification of the receiver circuit until the revolution is completed. At the beginning of reception the condenser C is charged by a switch S, which constitutes the armature of a relay and is opened when the drum B commences to revolve.

Title: Improvements in the cleansing of textile materials
IPC: C11D11/00
Filed: 1935-02-15
Abstract: Textile materials are cleaned by impregnation with an oil-soluble acid which forms a detergent with a base, then treating with a base so as to neutralize a portion only of the acid on the material and to emulsify and remove from the textile remaining acid as free acid together with the dirt by the action of the detergent so formed.  The acid is preferably an oil-soluble organic acid substantially insoluble in water, e.g. a naphthenic, oleic, stearic, palmitic or linoleic acid.  The base is preferably caustic alkali, also ammonium hydroxide or mono-, di- or tri-ethanolamine, or the like.  All textile materials may be so treated and particularly materials consisting of cellulose esters, since the treatment may be effected below 85 DEG  C., and so avoids delustring.  The acid may be applied by immersion, spraying, padding or like methods, the base may be applied in an aqueous bath.  In an example, a cellulose acetate fabric is padded with naphthenic acid and pressed to leave about 20 per cent acid on the fabric; after 1--2 hours the fabric is treated at 75 DEG  C. in a bath containing 1 gm. per litre of sodium hydroxide.  A portion only of the acid is neutralized, and the soap so formed emulsifies the free acid which leaves the fabric together with the dirt; after standing, sodium hydroxide is added to neutralize the bath; the fabric is finally scoured at 75 DEG  C. in a bath containing .25 gm. soda ash per litre.
