Title: Pin-hole detector for scroll-cut sheets
IPC: G01N21/89
Filed: 1959-09-28
Abstract: 857,751. Photo-electric pin-hole detectors. BLAW-KNOX CO. Sept. 28, 1959 [Oct. 15, 1958], No. 32864/59. Class 40(3). An arrangement for inspecting and detecting pin-holes in material which is cut into sheets and in which a sheet in which a hole has been detected is deflected from a normal delivery path to a reject store is designed to operate for scroll-cut sheets. i,e. with a severance line which is alternately projecting and recessed, or is of sinuous shape, to reject the sheet in which the pin-hole exists by means of a light source and one or more photo-electric cells in association with an opaque mask having a light-transmitting portion conforming to the shape of the non-linear line of severance of the sheets. In the case of a hole near the line of separation the arrangement discriminates between a hole in the trailing portion of a sheet and a hole in the forwardly projecting part of a subsequent sheet. As shown in Fig. 1 the material is fed from a roll C as a sheet S through a pin-hole detecting arrangement 11 comprising light sources 23, 24 disposed above a housing 25 enclosing one or more photo-electric cells 26 and having an opaque cover forming the mask 30 with a slit 31 corresponding exactly with the configuration of the line of separation to be effected by the device 14 comprising rotating cutting blades. The separated sheets S<SP>1</SP> are passed to conveyers 16, 17 providing a feeding rate slightly greater than that effected by rollers 12. When a hole is detected a pulse from the photocell 26 and amplifier 27 is passed to a control device 28 operating in conjunction with switch members operated by the rollers 12 and the cutter device 14 to operate an electro-magnet 21 so that a deflector and feeding plate 18 raised slightly before it is reached by the leading edge of the plate S<SP>1</SP> which has a pinhole and which immediately drops into a container for the reject plates 20. Plates S<SP>1</SP> without defect are fed over the plate 18 and by conveyer 17 to a container for such plates 19. With the opaque mask 30 Fig. 2, having a slit 31 conforming to the severance line 32 for the sheets, a hole a which is indicated as a hole a<SP>1</SP> relative to the line 32 and as a hole a<SP>11</SP> in the trailing portion of the severed sheet 34 will produce a pulse in advance of that produced by a hole b disposed at b<SP>1</SP> relative to the line 32 and appearing at b<SP>11</SP> in the projecting portion of the sheet 33, so that for a hole a the deflector 18 would be operated to direct the appropriate sheet, whilst for a hole b the subsequent sheet S<SP>1</SP> would be passed to the container for faulty sheets. In the photo-electric arrangement, Fig. 8, the light sources 47 are associated with a reflecting hood 46 and the housing 50 for the photo-electric element 51 has an opaque cover 52 provided with the shaped slit 53 and over which the sheet S of material is fed.

Title: Improved hydraulic shock absorber
IPC: F16F9/348
Filed: 1946-11-07
Abstract: 618,797. Hydraulic shock - absorbers. GENERAL MOTORS CORPORATION. Nov. 7, 1946, No. 33069. Convention date, Dec. 4, 1945. [Class 108 (iii)] A hydraulic shockabsorber comprises a piston 70 movable in a cylinder 27 supplied with fluid from a reservoir 30, communication between the reservoir and cylinder, and between both sides of the piston, being established through separate valve mechanisms at least one of which allows comparatively unrestricted flow in one direction and restricted flow in the other direction, the restricted flow being produced by two valves in series, one of which has a small permanently open orifice. In the construction shown in Fig. 1, a valve cage 28 controlling flow between the cylinder 27 and reservoir 30, comprises a central port 35, controlled by a one-way valve 37 which permits comparatively free flow into the cylinder, and a series of ports 45 controlled by seriallyrelated resilient disc-valves 48, 50. The valves 48, 50 are secured in closed positions against respective seatings 46, 47 by spinning the material of the lower edge of the cage 28 at 49. The valve 50 is a multiple disc valve of greater strength than the valve 48 and has a peripheral notch which constitutes a permanently open orifice through the valve 50. An annular flanged-portion 151 of the cage 28 impedes flow through the valve 50 and eliminates hissing noises. The piston 70 has an outer ring of ports 71 controlled by a disc valve 67 held resiliently on to its seating by a radiallyfingered valve spring 65 and a nut 64, and an inner ring of ports 69 controlled by seriallyrelated resilient disc-valves 76, 77 (Fig. 5). The valve 76 is a multiple disc-valve of greater strength than the valve 77 and has a peripheral notch constituting a permanently-open orifice. In an alternative construction the valves 76, 77 may be interchanged so that the stronger valve with the orifice is positioned nearer the outer end of the piston rod 23. Similarly, the position of the valves 48 and 50 may be interchanged. An annular partition 90 in the reservoir 30 which is positioned above the lowest liquid level, has a series of ports 91, free flow through which is controlled by an annular valve 94 having small openings aligned with the ports 91. Operation.-On compression, liquid flows freely upward through the piston 71 and the valve 67, and pressure below the piston raises the weaker valve 48 and flow commences through the valve 48 and through the notch 51 in the valve 50 to the reservoir. Further pressure increase causes the valve 50 to be opened. On rebound, orifices 68 in the valve 67, which is held in closed position by pressure above the piston, allow flow through ports 69 and the notch in the valve 76 to open the weaker valve 77. On further movement the valve 76 also opens.
