Title: Improvements in or relating to electric batteries or cells, electrodes therefor and methods of producing such electrodes and materials therefor
IPC: H01M4/54
Filed: 1958-11-12
Abstract: 905,603. Batteries. YARDNEY INTERNATIONAL CORPORATION. Nov. 12, 1958 [Nov. 13, 957], No. 36.32/58. Drawings to Specification. Class 53. The active material of the positive electrode of a secondary battery consists of powdered silver or silver oxide, the average size of the particles being less than 5 Á. With particles of this size the battery can be fully charged at a lower voltage than that at which the higher oxide of silver is produced. The silver may be prepared by reducing with formaldehyde silver oxide having an average particle size of 2.5 Á. In another method, silver oxide having a particle size of 2Á is placed on a horizontal cathode in potassium hydroxide solution and reduced electrolytically. Other methods include mechanical attrition, electrochemical deposition, and reduction of silver halides by photo - chemical means. Specifications 680,793, 682,164, 682,165, 698,405, 701,641 and 701,644 are referred to.

Title: Method and apparatus for automatically loading cartons
IPC: B65B7/20
Filed: 1974-08-20
Abstract: 1485561 Packaging; driving conveyers RA JONES & CO Inc 20 Aug 1974 [20 Aug 1973] 36619/74 Headings B8C and B8A Packets 41 are arranged in stacks in compartments 26 and the stacks are then raised into cartons 19. A conveyer 44 feeds the packets to a transfer wheel 46 which has projections 47 forming individual compartments for the packets. Chains 190 extend around a second wheel 48 and have bars 192 which form compartments to receive a group of packets from the wheel 46. Chains 190 are periodically accelerated to move the bars 192 rapidly past the points where packets are transferred between the wheels by periodically forming the chain (214) which drives the chains 190 into a loop downstream of a sprocket which drives the wheel 48 and chains 190. The chains 190 extend downwardly from the wheel 48 to feed each group of packets into a shoot 52. When each bar is laterally withdrawn from the shoot a group supported thereby falls on to fingers 54 extending into a compartment 26 on a turntable 28. The fingers can be lowered beneath the turntable to permit indexing of the turntable. At a subsequent station a vibrator (282, Fig. 11, not shown) engages the bottom of the stack of packets in the compartment and a pivoted head 276 the top of the stack to compress the stack. A suction cup 60 pulls a carton blank 14 from a magazine 12 against a curved surface 61 and a projection (62) partially to erect the carton which slides down a plate 16 on to a conveyer 20. The leading carton on the conveyer is pushed between tabs 77-83 on a wheel 22 and erection of the carton is finished by the wheel moving it past the end of the conveyer. The wheel is indexed to bring the carton above a compartment 26, exact positioning of the wheel being ensured by a detent roll engaging in a notch in the wheel. An elevator 120 raise a stack from the compartment 26 into the carton and holding fingers are projected from the wheel to support the stack within the carton. At the top position of the wheel the carton is pushed from between the tabs 77-83 to between spring members and up an inclined plate 184 on to a platform 34, for discharge in groups by a pusher 36. The packets 41 may be stacked in the compartments 26 as pairs of interconnected packets. The packets may be inserted into the carton in pairs or may be separated in the compartments by a vertically movable cutter.

Material in an upright cylindrical container 1, which is moved in a circle by an agitating vane 2, is discharged by a wedge-shaped scraper blade 3 mounted in an aperture in the container wall and directed counter to the direction of movement of the material. The blade is pivotable about an axis 5 by a grip rod 4, and a portion 7 of the container wall can 'be pivoted outwards about a trunnion 8, the discharge outlet being formed between the scraping edge 6 and the wall portion 7. Material is then carried by a screw conveyor 9 which may be of increasing diameter (see Figs. 2, 4, 6 and 8, not shown). The edge of the scraper blade may be vertical as shown, or inclined outwards from the bottom upwards providing a triangular or trapezoidal discharge outlet, (see Figs. 3-8, not shown).

Title: Improvements in or relating to electrostatic image developing apparatus
Inventor: FRANCIS FREDERICK GEORGE
IPC: G03G15/09
Filed: 1959-10-29
Abstract: 890,531. Electro photographic developing apparatus. CARIBONUM Ltd. Oct. 24, 1960 [Oct. 29, 1959], No. 36782/59. Class 98(2). Apparatus for developing a latent electrostatic image on a copy sheet by applying thereto developer powder comprising toner particles carried on magnetic carrier particles includes a rotary drum comprising annular magnets and annular, non-magnetic spacers arranged alternately along the axis of the drum and each having a peripheral surface which forms part of the peripheral surface of the drum, the arrangement being such that the drum is rotated and a brush of the developer powder is formed on the surface of the drum and is moved in contact with the copy sheet as the latter is advanced past the rotating drum. As shown, the apparatus includes a drum 14 rotatable on a shaft 15 and comprising alternate annular magnets 16 and non-magnetic spacers 17. A brush 39 of developer powder forms on the drum as it rotates and development of latent electrostatic images on copy sheets as they pass along the path indicated by the arrows 12 takes place at the lowermost point of the drum. The direction of movement of the copy sheets may be the same as or opposite to that indicated by the arrows 12 and they may be moved with any convenient speed relative to the drum 14. Developer powder depleted of toner particles is scraped from the surface of the drum by pivotable scraper 26 and after mixing with additional toner particles introduced through hopper device 38 is returned to the surface of the drum by adjustably inclined magazine plate 20. Thorough mixing of thedepleted developing powder and replenishment toner particles is obtained by an agitator device comprising rods 30a, 30b, 30c, mounted on a longitudinally displaceable rod 28 which is moved to and fro against the bias of a compression spring 37 by means of a cam plate 32 mounted on shaft 15 and engaged by a roller 36 on the rod 28. To avoid banding of the developed image owing to the developer powder being more strongly attracted in the region of the magnets 16, the drum 14 may have a thin covering of a non-magnetic material, two or more drums may be provided slightly offset with respect to one another, the sides of the annular rings may be corrugated, the drum may be axially reciprocated, or the magnets 11 and spacers 17 may be elliptical and inclined to the axis of the drum. Electromagnets may be used in place of magnets 16.
