Title: Improvements in railroad spikes
IPC: E01B9/06
Filed: 1919-07-14
Abstract: 152,736. White, A. E., (American Spike Co.). July 14, 1919. Drive-screws.-Relates to railway spikes of the drive-screw type. In the construction shown in Figs. 1 and 4, the spike is provided at the upper end with a cylindrical throat B and a conical point A and the shank has four faces C divided from each other by spiral fins D. The faces Care formed with a double convex curve and extended to form walls of the fins D. One side of each fin is made as a plane surface F, a sharp edge G being formed where the surface F meets the rounded part of the fin. The surface F makes an obtuse angle with the curved surface face C. When driven into wood, the fibres of the wood settle in the angular channels H, and the edges G bite into the fibres and prevent counter-rotation. In another construction shown in Figs. 6 and 7, the plane surfaces F of the fins are made radial, and the curved faces C merge into portions E<1> lying on a circle. The fins are continued down to the end A<1> of the spike, which is blunt and cruciform in shape. In this construction, the surfaces of the fins resist an upward pull and the fins at the end of the spike resist counter rotation.

Title: Improvements in spinning artificial filaments
IPC: D01F2/06
Filed: 1945-07-11
Abstract: In the manufacture of artificial fibres by spinning viscose through a spinneret having an orifice area density of at least 2500 orifices per inch of circular diameter into an acid spinning bath, the face of the spinneret is coated with a condensation product of ethylene oxide and a partial acyl ester of a polyhydric alcohol containing a hydrocarbon chain of at least 8 carbon atoms, the product having an average total oxyethylene content of at least 8 oxyethylene units per molecule, in order to prevent the adherence of gas bubbles to the spinneret face.  Condensation products of ethylene oxide with partial esters of the anhydro derivatives of polyhydric alcohols may also be employed. Specified polyhydric alcohols are the glycols, glycerol, erylthritol, pentahydric alcohols, mannitol, sorbitol, dulcitol, heptahydric alcohols and the sugars, e.g. glucose and sucrose, and specified anhydro derivatives are mannitan, sorbitan, mannide and sorbide.  The esters may be derived from pelargonic, capric, lauric, myristic, palmitic, margaric, stearic, oleic, ricinoleic and hydroxy stearic acids.  In the examples, artificial threads are obtained by extruding viscose through a spinneret, the face of which is coated with a condensation product of ethylene oxide with sorbitan monolaurate or ethylene oxide with glycerol mono-oleate. The ethylene oxide-sorbitan monolaurate condensation product may be prepared by heating sorbitan monolaurate with sodium methylate as catalyst in an autoclave and gradually adding ethylene oxide to the mixture which is then maintained at 105 DEG  to 110 DEG  C.

Abstract: 1497853 Multi-spindle machine tools J P ALAFUZOY and A M ITIN 30 April 1976 17812/76 Headings B3T and B3B  In a vertical multi-spindle machine tool which has a work-table support column 3 with a tapered portion on which is indexably mounted an annular work table 1 which carries a plurality of fluid actuated work clamping devices 2, means is provided to permit the passage of hydraulic fluid under pressure from a source 8 via the work table and column to the workpiece clamping devices to facilitate the maintenance of hydraulic pressure to the clamping devices both during the indexing of the table and at the respective indexed positions of the table. The tapered portion of the column is provided with an annular groove 9 which with a co-operating surface of the worktable forms a duct which is connectable to the fluid pressure source 8. The table is provided with a series of ducts 4 which in each of the indexed positions of the table 1 is aligned with a passage 5 in the column, also connected to the fluid source. Thus, at each of the indexed positions fluid pressure can be maintained at the work clamping devices to ensure that they grip the workpieces. During the rotation of the worktable between the indexed position fluid pressure is maintained by the connection of the groove 9 with the passages 5, the groove being of sinusoidal configuration so that regions of the groove coincide with the outlets 6 of the passages 5. This arrangement greatly reduces the fluid leakage during the operation of the machine.

Title: Key telephone systems using pushbutton or rotary dials
IPC: H04Q1/30
Filed: 1970-04-16
Abstract: 1,272,723. Interconnection systems. INTERNATIONAL STANDARD ELECTRIC CORP. 16 April, 1970 [23 April, 1969], No. 18201/70. Heading H4K. An intercommunication system has subscriber stations 50 connected to a plurality of exchange lines 51 and to a single common intercom line 52 and these connections are selected by operation of respective keys. The called party on the intercom line is selected by operating a dial or push-buttons. The solution equipment thus has to accept either open-circuit pulses or multifrequency tones. In both forms of signalling the number of the called party is finally stored in binary form on relays in the binary digit store 58 and causes the respective relay contacts in trees 59, 60 to be operated to supply a calling signal, both ringing and a flashing lamp, to the required station. Tone frequency signals on a two out of seven code are detected in filters 55 and pass to binary converter 57 which consists of AND gates whose outputs energize the respective relays in store 58. Dial pulses are detected as the opening of a relay contact in detector 64 and are then repeated as short duration standard height pulses which are used in converter 65. Use of the actual dial pulses could cause erroneous operation of the relays in store 58. Each pulse received causes the respective ones of the binary relays to be energized so that the energization pattern indicates the number of pulses received and causes contact trees 59, 60 to be set so that the required station is signalled. The control unit provides the signalling and other call signals and includes a circuit 62 which detects either one or two stations to be off hook and alters the output of the signalling control accordingly. Call signalling includes providing a steady light at all stations to indicate that the common line 52 is seized and the provision of both a flashing light and single or repeated ringing signal at the called station. When the called station goes off hook the light stops flashing and burns steadily.
