Title: Improvements in or relating to apparatus for straining liquids and comminuting solids in a flow of liquid
IPC: B01D33/06
Filed: 1943-01-12
Abstract: 567,040. Filtering sewage. DURDIN, A. C. Jan. 12, 1943, No. 575. Convention date, Dec. 22, 1941. [Classes 46 and 111] Comminuting apparatus, particularly for sewage, comprises a rotating circular drum having perforations in its cylindrical face and a cutter member mounted adjacent its periphery and cooperating therewith to comminute the solidmaterial collected thereon, and means for guiding a fluid stream diametrically through the drum so that the comminuted material is flushed. or washed from the drum by the fluid stream emerging from the cylindrical surface. In the construction shown, the apparatus comprises a drum 22 driven by an electric motor 29, the drum and motor being mounted on a framework which can be removed bodily from the chamber 10 to which it is normally secured by bolts 19. The drum is mounted on a shaft 23 and comprises end plates joined by bars 32, the latter being braced at intervals by circumferential ribs 33. The bars are formed with grooves 41, 42, for receiving the frame members 35, 36 of screen sections 34, which are secured to the bars by screws 36. The bars also carry the blades 44 which co-operate with a fixed blade 49 for comminuting the material which is too large to pass through the screen. A grate 53 is provided above the drum to prevent the passage of large particles when the liquid attains an unusually high level, and a plate 51 is mounted beneath the drum and close to it to prevent flow of fluid between the drum and the base of the framework. As viewed in Fig. 4, the drum revolves anti-clockwise and thereby carries the material, which is flowing towards the drum from the right, upwards to the blade 49. The fluid after entering the drum passes into a discharge conduit outside the drum and to the left of it as seen in Fig. 4. In a modification, the drum revolves clockwise, the blade 47 being mounted between two plates rotatably mounted one at each end of the shaft 23. A stop plate adjacent the base of the framework normally holds the blade in a fixed position to co-operate with the blades on the drum, but when adjustment of the blade is deemed necessary, access to it is effected by rotating the end plates on which it is mounted. The end plates also carry a plate which, when the blade is against the fixed stop, is positioned adjacent the grid 53 to seal the space between the drum and the grid.

Title: Cutter guide means for dry shavers
IPC: B26B19/04
Filed: 1964-01-06
Abstract: 987,665. Dry shavers. SPERRY RAND CORPORATION. Jan. 6, 1964 [Jan. 14, 1963], No. 595/64. Heading B4B. In a cutter head unit for a dry shaver comprising a cutter movable with respect to a stationary cutter, the movable cutter is provided with guide means having flexible portions bearing against the stationary cutter to prevent undesirable movement of the movable cutter when it is moved relative to the stationary cutter. As shown, an inner cutter 22 is reciprocable within an outer cutter 18 and the cutter 22 carries a nylon guide 40 provided with legs 41, 42 the feet 43 of which engage the inner side walls of the cutter 18 to prevent lateral movement of the cutter 22 when it is reciprocated. The guide has shoulders 45, 46 engaging the inner side walls of the cutter 22 to prevent accidental dislodgment of the guide from the cutter. Clamp fingers 15 on the shaver casing are engageable with lips 16 on the cutter head. The guide means may be used with a cutter head in which (a) the inner cutter rotates within the outer cutter or (b) the outer cutter is moved relative to a stationary inner cutter. Specification 798,757 is referred to.

Abstract: 882,613. Stuffing-box substitutes. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Jan. 7, 1960 [Jan. 14, 1959], No. 601/60. Class 122 (5). The escape of a noxious fluid from a chamber 1, Fig. 1, through an opening 4 through which may pass a shaft R comprises a chamber 7 connected by the escape opening with the chamber 1 and continuously fed at a controlled volumetrically constant flow rate with a sealing fluid by a pump 8, a compensating chamber 9 subdivided by a movable fluid-tight partition 10 into two compartments 9a, 9b respectively connected to the chambers 1, 7 by pipes 12, 13, and means actuated by the shaft R within the opening 4 for ensuring a continuous flow of the sealing fluid from the second chamber to the first. The partition 10 may be a free piston or a flexible non-resilient fluid-tight diaphragm and communicates any pressure variations in the chamber 1 to the chamber 7. The means causing transfer of the fluid from the chamber 7 to chamber 1 consist of helical elements 20 mounted on the rotary shaft R. In Fig. 3, the shaft 40 of a centrifugal pump 43 for circulating a noxious gas is shown as being sealed where it passes through an opening in the chamber 1. In this case the chambers 1, 7 are again connected to a compensating chamber 9, a pump 8 supplies sealing gas to the chamber 7, and helical elements 20 on the shaft ensure flow of sealing gas into the chamber 1. In addition, further helical elements 27 on the shaft cause a flow of sealing gas from the chamber 7 into a chamber 21 enclosing the shaft bearings 45, 46, the gas passing therefrom to a chamber 25 for recirculation. A pump 47 feeds lubricant to the shaft bearings, whence it is drained back to a reservoir 48 by ducts 52; any lubricant that is carried away by the sealing gas to the chamber 25 is filtered out in that chamber and passed through a pipe 59 to the reservoir 48. Coolant circulating coils 56, 57 cool the chamber 25 and reservoir 48, and the wall 41 of the pump casing 42 is formed as a hollow wall to constitute a cooling jacket which is fed with coolant by a pipe 58.

Abstract: PURPOSE:To easily perform the correction of wiring within a substrate, and to effect high mounting density of a multilayer circuit wiring board by placing wiring pattern on the same plane as a repair pattern as well as forming the repair pattern within an inner layer. CONSTITUTION:A terminal connection pad 4 positioned on the surface layer of a substrate 1 is connected to an wiring pattern 6 through a conductive via 5, and the connection pad is arranged in close proximity to a repair pattern X7 and a repair pattern Y8 located in the vicinity of the pad 4. That is, the wiring pattern 6 and the repair pattern Y8 are arranged flush with each other in a substrate inner layer surface (a second pattern 12). Also, the wiring pattern 6, the repair pattern X7 and the repair pattern Y8 are arranged closely adjacent to each other with a minimum insulatable pattern pitch maintained between them. Thereby, since the substrate has an arrangement in which various types of conventional repair pads are eliminated from the substrate surface, it is possible to improve the mounting density of electronic circuit parts.
