Inventor: HUFNAGL WALTER
IPC: B21C3/12
Filed: 1965-02-20
Granted: 1966-09-09
Abstract: 1,095,464. Rolling; twisting. W. HUFNAGL. Feb. 22, 1965 [Feb. 22, 1964], No. 7555/65. Headings B3E and B3M. A method of working bar or wire comprises passing a continuous length in the cold state through an opening formed by a set of rotatable rollers for forming ribs and/or grooves in the bar or wire and through rotating means for continuously imparting a rotational movement while the bar or wire is passing through said rollers, the rotating means having independent drive means. The rollers rotate in a plane perpendicular to the direction of movement of the bar or wire. A torsional movement is thus imparted thereto and a fractional or compressive force may also be applied. An additional set of rollers may rotate it in the desired direction. Such additional rollers can be mounted in front of or behind the main rollers. Such rollers may impart a slight shaping operation to produce a certain strength and/or elongation. The rotary movement can also be obtained by driving the main rollers and also the tool head in which the rollers are mounted. If a relative movement is produced between the rollers and the tool head, a rotatory movement is also imparted to the wire.

Title: Fused electric switch
IPC: H01H71/12
Filed: 1967-01-02
Abstract: 1,135,351. Snap-action switches; automatic circuit-breakers. WESTINGHOUSE ELECTRIC CORP. 2 Jan., 1967 [3 Jan., 1966], No. 21/67. Heading H1N. A switch 11 is mounted in an insulating casing 5 which also carries a dismountable fuse carrier 13 carrying a fuse 71 in series with the switch contacts 15, 17, means being provided to prevent removal of the fuse unit 13 while the contacts are closed. The switch comprises a pivoted dolly 41, a contact arm 27 pivotally supported upon it and an over-centre tension spring 37 between the contact arm 27 and a fixed bracket 33. The fixed contact 15 is carried on a terminal member 19 which also serves to mount the switch upon a bus-bar (not shown). A nose 139 on the dolly 41 obstructs a projection 119 on the fuse unit 13 to prevent its withdrawal. In addition, projection 119 is arranged to strike the nose 139 so as to move the switch to its open position when the fuse is inserted although the switch is normally prevented from closing while the fuse unit is missing due to a hook 117 engaging with a fixed abutment 115. When the fuse unit is inserted its projection 119 engages the abutment 115 and hook 117 cannot engage with it but if the fuse unit is not properly seated, for instance because an overrated fuse has been inserted (Fig. 10, not shown), a gap exists between 119 and 115 permitting the hook to engage between them and prevent closure of the switch. The fuse unit consists of an L- shaped insulating member 87 carrying a spring clip 77 supporting one end of the fuse and a spring blade 93 engaging the other. When the fuse unit is inserted the blade 93 biases the fuse against a terminal structure 67 while the spring clip 77 engages a resilient blade contact 57 to complete the circuit. A lamp 99 in parallel with the fuse to indicate its failure is visible in the handle 97 of the fuse unit. The switch may be provided with automatic tripping mechanism (not shown).

Title: Three-dimensional 1-transistor cell structure with a trench capacitor for a dynamic semiconductor memory, and method for producing the bit line contact
Inventor: KUESTERS KARL-HEINZ DR
IPC: H01L21/82
Filed: 1995-01-19
Abstract: In the arrangement, in which the capacitor for the charges to be stored is designed as a trench capacitor (9) in the substrate (1) and is arranged beneath the selection transistor with insulated gate electrode and connected in an electrically conducting manner to the source/drain zone (23) of the said transistor, the bit line contact (BL) for connection to the selection transistor is of self-aligning design on the drain region (23) situated in the semiconductor substrate (1) and overlaps the gate electrode (18) covered on all sides with insulating layers (19, 20) and also the adjacent field oxide region. The insulation layer situated beneath the bit line (BL) and above the gate level (18, 19) is a triple layer (29, 25, 26) composed of silicon oxide/silicon nitride/silicon oxide and brings about the self-aligning overlapping contact during the etching of vias (24) as a result of carrying out special etching steps. As a result of the positional inaccuracy due to the saving in lithography, the space requirement of a memory cell can be reduced by approximately 20%. The invention is used in the production of 4-megabit DRAMs.

Patent GB-621529-A (GB)
Title: Drop hammer
IPC: B21J7/24
Filed: 1947-01-07
Abstract: 621,529. Power hammers. CHAMBERS-BURG ENGINEERING CO. Jan. 7, 1947. No. 526. Convention date, Oct. 8, 1946. [Class 83 (iv)] A drop hammer of the kind operated by air or other elastic fluid under pressure, comprises a ram adapted to drop freely by gravity, a pressure fluid actuated piston to raise the ram, clamping means which automatically hold the ram in its raised position, and means to render the clamp ineffective. The hammer comprises side frames 2 between which slides the tup 7, connected by a rod 6 to a piston 5 movable within a cylinder 4. The bottom of the cylinder may be connected to a source of pressure fluid or to exhaust by means of a valve 36, the sliding element 38 of which is operable by a vertical rod 58 acting through a bellcrank lever 61. Disposed on opposite sides of the rod 6 are two blocks 10, 11 lined with friction material 12 and pivoted between two parallel plates 14 which are in turn pivoted at one end 17 to the machine frame and at the other end 21 to a link 22. A rocking lever 23 pivoted to the machine frame at 25 is connected to the link 22 at one end and to the rod 30 of a fluidpressure actuated piston 29 at the other. A spring 27 biasses the rocker so that the ends 21 of the plates 14 are normally depressed to move the blocks 10 and 11 into gripping engagement with the rod 6. The clamp may, however, be released to allow the tup to drop by actuating a treadle 34 to permit pressure fluid to flow into the cylinder 28 and depress the piston 29. As the tup approaches the anvil 8, it engages a dog 48 at the lower end of a pivoted lever 45 which, through levers 53, 54 moves the rod 58 controlling the valve 36 so that pressure fluid is admitted beneath the piston 5. As the tup rises again an upper bevel 51 thereon engages another dog 49 on the lever 45 to cut off the supply of pressure fluid and the tup continues its upward movement by momentum and by the expansion of the fluid already supplied. When the bevel 51 reaches an upper dog 50, the cylinder 4 is connected to exhaust and the tup either falls again or is held up by the clamping blocks 10, 11 according to the position of the treadle 34. An upward movement of the rod 6 acts to release the brake.

Abstract: 1,088,796. Advancing mine roof supports. A.G. WILD & CO. Ltd. March 25, 1966 [Jan. 6, 1965], No.535/65. Heading F1P. In a mine roof support unit having two doubleacting fluid operated rams 100, 102 connected to a face conveyer, the rams being extendable to advance the conveyer and retractable to advance the support up to the conveyer, manually or automatically operable valve means are provided for apportioning the flow of fluid to the two rams to cause the support unit to be advanced to a position in correct alignment with the face conveyer. The. form of automatically operable valve means shown, comprises a flow control valve 1 having a piston 2 movable to control the opening of two ports 1b 1c, connected to the retracting ends of rams 100, 102 and supplied with fluid through a port 1a. Fluid exhausted from each ram extension end is supplied to respective valve ports 1d, 1e to act on opposite ends 2b, 2a of the piston 2 before exhausting through restricted ports 1f, lg. If the exhaust flow from one ram is higher than from the other ram the pressure acting on the piston end 2a or 2b in communication therewith increases, thereby moving the piston to reduce the flow to the leading ram and increase the flow to the trailing ram. To avoid the necessity during ram extensions, for fluid exhausted from the retraction ends having to pass through the flow control valve 1, by-pass valves 3 operable in response to pressurization of the extension ends of the rams are provided. In a modification, Fig. 6 (not shown), additional valves are provided to enable fluid supplied to cause ram extension to by-pass the flow control valve 1. Two other embodiments, Figs. 7 and 9 (not shown), are described in which the flow control valve is responsive to the pressure in, or flow to, the retraction end of each ram.
