IPC: G03G15/01
Filed: 1970-02-18
Abstract: 1306821 Electrographic processes ELECTROPRINT INC 18 Feb 1970 [18 Feb 1969] 7842/70 Heading G2H An electrostatic latent image comprising two layers of opposite charge is formed on a screen and developer particles are projected through the apertures of the screen to deposit on a receiver in imagewise configuration, the process being repeated to produce amulti-colouredcopy. As shown, an endless photo-conductive screen 600 having a conductive backing is imagewise exposed through successive colour filters 623 and subjected to a field Ec, to produce latent colour separation images. Optionally the screen is precharged at 609. A conductive conveyor 630 held at a potential E p  feeds copy sheets 631 past toner sources 640-643 and, as each latent image passes, the appropriate source is energized with a potential E T  so that toner is propelled by a rotating brush through the screen and onto the paper. E T  is adjustable to control toner deposition. Vacuum cleaners 651-653 clean the screen. The whole process is controlled by a timer 663. In Fig.36, belt 675 may be insulating and drum 674 photoconductive. In another modification, a latent image is formed on an insulating plate Figs.8-10; (not shown) or on a photoconductive plate Figs. 14- 16, 31,32; (not shown) and transferred to an insulating screen, which is optionally precharged Figs. 11-13; (not shown). In Fig.33 (not shown) a photoconductive screen (511) is charged in a vertical position by a reciprocating corona discharge device (519) exposed and then pivoted up into a horizontal position for toner projection. In Fig. 37 (not shown) dichroic filters (707,709) produce colour separation images on screens (710-712). In Figs. 38-44 (not shown), a multi-colour filter (750) is placed over a screen (755), and the screen is subjected to a field of one polarity while being uniformly exposed to light, and then to a field of the opposite polarity while being imagewise exposed to a full colour image. Developing is carried out by registering an apertured mask (770) in a different position with respect to the screen for each differently coloured toner. Ink droplets or aerosols may be used instead of toner powder.

Title: Improvements relating to metallic band or wire tying machines
IPC: B65B13/32
Filed: 1937-03-20
Abstract: 489,050. Welding; strapping-machines. SUTTON, J. R. March 20, 1937, No. 8226. [Class 83 (iv)] [Also in Group I] In a machine for tensioning metallic bands or wire ties round packages and securing the ends by welding, and having two or more fixed electrodes co-operating with complementary sequentially-operated movable electrodes for connecting the ends by a number of successive spot welds, such as is described in Specification 458,197, the fixed electrodes are isolated from the electric circuit when they are inoperative so as to avoid short circuits and thus waste of current when a weld is being effected by another pair of electrodes. The band 3 may be held at one end by a pivoted spring-released grip 4 and tensioned by a ratchet-operated knurled wheel 5 mounted on an adjustable eccentric 8. A hand-operated shaft 23 carries a cam 25 for operating a shear blade 14 for cutting the upper end of the band to length, cams 26, 28 engaging in apertures in fibre slides 20 for operating movable electrodes 16 sequentially, and a cam 27 for operating a metal cage 22 provided with a fibre base pad 31 for resiliently holding the parts during welding. The cams 26, 28 engage spring-leaf bridges 29 in the slides to give resilient pressure and the cam 27 operates through a resiliently mounted base 30. The electrodes 16 are connected to the terminal 33 of the welding circuit through metal facing sheets 35 on the slides 20 and a flexible bridge connector 36. The fixed electrodes 17 are mounted on spring arms 18 in a base provided with an insulating layer 19. The arms are bent at 40 to form the fixed contacts of switches, the movable contacts 37 of which are connected to the terminal 34 and operated so as to close the switches by cams 39 on the rear edges of the slides, so that the switches are only closed when the slides are depressed. In a modification, the resilient arms carrying the fixed electrodes may be depressed so that the electrodes are retracted through holes in a fibre pad out of contact with the work when their co-operating movable electrodes are raised. In another form, the movable electrodes 16 are carried by the plungers 41 of solenoids 46, the armatures 43 of which are pressed by springs 45 against collars 44 on the plungers and when energized engage the collars 48 on the plungers through springs 47 to force down the electrodes. The plungers are provided with insulation pieces 49 so that current from one terminal of the circuit through contacts 50, 51 to the fixed electrodes is cut off when the electrodes are raised. The current supply to the several solenoids is controlled by a rotary switch. Such switch may also incorporate contacts for controlling the current supply to the electrodes 17.

Title: Improvements in conveyor systems
IPC: B61B10/02
Filed: 1963-03-01
Abstract: 1,029,581. Conveyer systems. JERVIS B. WEBB CO. March 1, 1963 [March 16, 1962], No. 8227/63. Heading B7L. A conveyer system has carriers 10, Figs. 1, 3, movable on a track 12 by an endless chain 22 on a track 20 by engagement of member 30 with a pusher 23; during the transfer to a main line 14, the tracks 12, 20 converge at 46 so that as pusher 23 leaves member 30 at point 42, a second pusher 23 engages a member 40 on carrier 10 to move the carrier into a position in which a pusher 56 on main chain 24 can engage member 30. A switch is provided at point 42 and the branch tracks 12, 20 diverge to their normal spacing at 58. The member 30 is retractable along a slot 33 and is retracted when an abutment, e.g. a device 36 carried by a preceding carrier, strikes and rotates arm 34 to withdraw member 30 from engagement with pusher 23. A stop 48 comprises a pair of arms 51, 52 which are projected by a pneumatic cylinder 49 to withdraw the member 30 and hold the carrier until an empty pusher on the main chain 43 is approaching the junction. The two chains 22, 43 are operated in synchronism. In Fig. 2, the carriers 10 are transferred from main line 60 to branch line 62 by the descent of main chain 66 at 68 to engage a pusher with member 40. The branch chain 65 descends at 76 to engage a pusher with member 30 to prevent jamming of the pusher and member 30; the two chains do not operate synchronously.

Title: Improvements in electrodialysis
Inventor: ARDEN THOMAS VICTOR
IPC: B01D61/44
Filed: 1955-03-22
Abstract: 828,898. Electrodialysis. PERMUTIT CO. Ltd. March 15, 1956 [March 22, 1955], No. 8377/55. Class 41. In a process of electrodialysis in which two solutions are passed continuously through the alternate compartments of a cell comprising end electrodes and between these from 80 to 600 compartments separated by alternate cation- and anion-selective membranes, at least one solution is passed in parallel streams through the compartments of groups into which one set of alternate compartments is divided, the streams on emerging from one group combining and passing to the next group. Either both solutions, viz. that from which ions are to be removed and that which is to receive them, may be similarly fed through the cell or the electrolyte-collecting stream may be a simple series flow throughout its set of compartments. Preferably each solution is passed in parallel through the compartments of the series-connected groups forming its set, each group containing from 5 to 20 compartments and the number of compartments in the group decreasing in the direction of flow so as to obtain the same flow rate in all the compartments. As shown, the solution A from which electrolytes are to be removed passes as shown in full lines in Fig. 1 and the liquid C in which the electrolytes are concentrated follows the dotted line path. The two liquids are separated by membranes and spacers (see Fig. 2), as in Specification 769,307, each having a thickened edge 15, one flat face, and ribs 11 which together with the flat face of the next membrane define a compartment. Thus the liquid A in stream A 1  to be treated passes through the compartments of the first group formed in the faces of the cation-selective membranes 2, 4, 6 to the collection stream B for the treated liquid while the liquid C in stream C 1  which receives the transferred electrolytes passes through similar compartments of the first group in the faces of the anionselective membranes 3, 5 to its collection stream D. Thereafter stream B passes through compartments in the face of cation-selective membranes as at 8, 10 in the second group into stream A 2  while the stream D passes through compartments in the faces of anion-selective membranes as at 7, 9 in the second group into stream C 2 , and so on. By-pass holes as 14, 24 are provided in the membranes for passage of the liquid not to be treated in the compartment formed by the ribs of that membrane. Specification 758,650 is referred to.

Abstract: 582,993. Rotary disintegrators. BAMAG, Ltd., and MANNING, A. H. May 6, 1944, No. 8628. [Class 5 (i)] A rotary cutter or disintegrator to shear solely by impact material, e.g., grass, herbs, vegetable, beet leaves food waste, fish products &c. comprises a number of arms or blades 8 mounted for gyration at high speed on a shaft 1 located coaxially in a barrel 17 which forms part of a duct for gas. e.g., air to convey the material. The blades may be freely pivoted on spindles 7 so that they align themselves radially during operation by centrifugal force. The material to be cut and dried is fed by a screw conveyer 20 into a duct 18 and then passes to the barrel 17 where it becomes airborne owing to the suction of a fan 2 which then discharges the cut material and air through 11 and 12 to the casing 16 of a drier. The fan 2 draws hot gas from the drier casing 16 down the duct 19. Tailings or larger or heavier insufficiently dried pieces collect in an annulus 21 and are led back down the gas (air) duct 19 and go through the cutting zone again. The cutter may be used in various pneumatic transport systems, e.g., to cut silage before it is blown to the top of the silos or, in drying systems, to subdivide the material before it is blown into the stream of hot drying gas. The cutter blades 8 and tubular spacers 9 between discs 5 are all mounted on the spindles 7 passing from end to end. The blades are arranged to form a single-start or two-start helical progression for the material and are inclined like propeller blades with leading and if desired their trailing edges bevelled but they may be more blunt for tougher material. The inside of the barrel may have longitudinal ribs to prevent or retard any rotation of the bulk of the material that may be tend to be caused by the cutters.
