Patent GB-559342-A (GB)
Title: Riveting yoke
IPC: B21J15/20
Filed: 1942-12-09
Abstract: 559,342. Riveting. CHICAGO PNEUMATIC TOOL CO. Dec. 9, 1942, No. 17519. Convention date, Nov. 8, 1941. [Class 83 (iv)] To enable portable self-contained abutment riveting machines to be placed in position on work that would require an abnormally great separation of the snaps and consequently an undue proportion of idle stroke, one of the snaps is mounted to switch aside, after being unlatched from its working position. The moving snap 34 is carried by a holder having a conical portion leading to a hollow portion 33 adapted to surround the rounded end 32 of the yoke 11 bushed at 28 to guide a plunger 27 that serves both to lock the holder in position by engaging a recess 36 and to impart the riveting stroke thereto by pressure above the plunger of the end 26 of a lever pivoted at 25 and having a roller engaging a cam 23 reciprocated by a working piston 17 and smaller return piston 19 located in the handle 13 by which the tool is manipulated in conjunction with suspension means not shown. A block 39 sliding on the plunger 27 has trunnioned connection 42 with ears 38 projecting from the holder 33. A spring 43 engages a stirrup 45 secured in the block 39 normally to hold the plunger 27 seated in the recess 36 and a spring 44 attached to a clip 46 secured to the plunger 27 maintains the latter on engagement with the lever end 26. The sides of the part 33 of the holder are knurled to facilitate grip by which the holder is first drawn down against the spring 43 to affect disengagement at 36 after which it is swung forwards as shown in Fig. 1 giving the effect of a large gap. In a modification a similar mounting is employed for the abutment snap.

Title: Improvements in respirators
IPC: A41D13/11
Filed: 1945-07-10
Abstract: 597,960. Respirators. ABBEY, A. (American Optical Co.). July 10, 1945, No 17629. [Class 81 (ii)] A respirator comprises a face-engaging portion and a collapsable cup-like filter member of relatively thin filtering material having folded convoluted side walls such that in the collapsed position the contours of the apices of the folds lie one within the other. As shown, the face-engaging portion comprises a rigid frame 10 to which the felt, &c. filter member 11 is secured by cement 12. The material of the filter member is looped at 23 and the free edge attached to the frame by adhesive 24 to provide a face-engaging surface 26 which is coated with rubber latex, plasticized vinyl resin, neoprene, or other specified materials to provide a non-porous resilient surface. The loop portion may, if desired, be joined to frame 10 as a separate member, and in this case may be of rubber or other specified synthetic materials with or without fibres or other fillers. A valve 27 having a flap 34 is riveted &c. to the front wall of the mask, which is held in the extended position by the engagement with a clip 35 of a brace member 36 pivoted to frame 10. Other forms of latch are shown. The frame 10 may, if desired, be shaped to fit closely around the bridge of the nose. In another modification, the material of the filter member may be stuck to the outside of the frame with the free edge secured to the inside. Fig. 9 shows a further form in which the free edge of the filter member 73 is stuck to the frame 69, the material being looped at 71 to provide the distortable faceengaging portion. A coating 74 corresponding to coating 26, Fig. 2, is provided.

Abstract: 1,268,781. Rotary flowmeters. A. O. SMITH CORP. April 3, 1969 [April 4, 1968], No. 17645/69. Heading F1F. A rotary flowmeter comprising a turbine rotor assembly 5, Fig. 1, having helicoidal vanes 28 connected at their tips by a shroud 33 is rotatably mounted on a spindle 22 with slight axial clearance between upstream and downstream hollow bulletshaped mounting shields 3, 4 having a plurality of radial fin-like support members 7, 38 supporting the sheilds within a tubular housing 2 through which the liquid whose flow is to be measured passes. The upstream edge of each of the support members 7, 38 includes at least one intake through which liquid from the flow-path can pass to liquid pressure chambers 11, 37 within the shields 3, 4. The pressure chambers are open at their ends adjacent the turbine rotor so that the pressure within the chambers acts on the opposite sides of the rotor to provide balancing forces to position the rotor at all times midway between the shields. To provide maximum sensitivity the intakes are disposed with their intakes in the region of the highest stream velocity areas and the intakes in the downstream support members 38 are greater in number or larger in size than those in the upstream support members 7. The meter includes thrust bearings 24, 45. Screws 20, 50 allow access to nuts 23, 48 on the ends of the spindle to permit removal of the mounting shields and turbine rotor. Shoulders within the housing and a flow deflector ring 26 correctly position the parts within the housing.

Title: Means for ensuring machinery against breakage
IPC: B30B15/28
Filed: 1926-07-15
Abstract: 271,677. Georg, O. July 15, 1926. Connecting-rods.-In a safety device for heavy machinery, two parts of the pressure transmitting member of the machine carry co-operating helical surfaces restrained from relative rotation by means which are directly interposed between them and yield or break under a torque corresponding to an excessive axial pressure. In the crank-operated forging press shown in Fig. 1, the rear surface of the joint 1 Tests against the sleeve 2 which has steep screw threads 3 engaging the press rod 4. The spindle 5 of the joint 1 is connected to the sleeve 2 by a nut 6, and shearing studs 7, 8 in boxes 9, 10 secure the sleeve 2 against rotation in the press rod 4. When the pressure becomes excessive so as to shear the studs 7, 8, the sleeve 2 rotates and moves into the press rod 4. In the modification shown in Fig. 3, the spindle 12 is connected to the ram by a ball end 13; the spindle 12 is threaded directly into the press rod 11 and is held against rotation by shearing studs 14, 15. In a further modification shown in Fig. 4, which is particularly adapted for rolling mill supports, two sleeves 15, 16 contacting along helical edges 17, 18 are held against relative rotation by a breaking bolt 19 with square heads 20.

Title: Improvements in the manufacture of ferro-cobalt
IPC: C25C1/24

Abstract: 416,528. Electrolytic separation of cobalt alloys. BOSQUI, F. L., N'Kana, Northern Rhodesia, and RHOKANA CORPORAT10X, Ltd., 13, Austin Friars, London. June 22, 1933, No. 17793. Drawings to Specification. [Class 41.] An anode comprising copper, cobalt and iron is dissolved in a cell containing an electrolyte having an acidity reckoned as sulphuric acid, exceeding three grams per litre. Most of the copper is deposited on the cathode or forms a sludge, while the cobalt and iron go into solution. The electrolyte is removed, heated to remove any dissolved copper, e.g. by cementation on cobalt or iron, and is placed in the cathode compartment of a second cell. A head is maintained in this compartment to cause a flow of electrolyte towards the anode to prevent access of anode ions to the cathode. The acidity of this electrolyte is maintained at an acidity less than three grams per litre. The catholyte may be circulated to keep it uniform. Under these conditions, ferro-cobalt is deposited on the cathode. Electrolyte from the anode compartment is withdrawn, acidified, and returned to the first cell.

Abstract: 1433613 Automatic control of electric generating plant WESTINGHOUSE ELECTRIC CORP 22 April 1975 18239/73 Headings G3N and G3R A steam turbine driven electric generating plant is controlled by a central digital processing means, which provides positioning signals for steam valves in response to operational input data and the contents of a memory in which is stored interrelated programs, a continuous comparison being made between the actual and commanded positions of the valves and an alarm being given if there is a disparity between the two greater than a predetermined value. Manual control is also provided, this being caused to track the processor derived command signals, and changeover is prevented if the alarm signal is present. If the alarm exists for more than a prescribed time the command position is brought towards agreement with the actual position and normal control is resumed, but if this adjustment is necessary repeatedly shutdown of the plant is initiated. The complete system is described in detail, using sixteen figures. The digital processor is a commercially available computer but certain aspects of the control may be in analogue form. For example, the speed is measured by three magnetic pick-up devices; one provides digital signals and the others analogue, and the computer selects the appropriate one according to (unspecified) dynamic conditions.
