Title: Improvements in remote starting and reversing devices for internal combustion engines
IPC: F01L13/00
Filed: 1931-07-24
Abstract: 374,675. Starting, stopping, and reversing. MASCHINENFABRIK AUGSBURG-NURNBERG AKT. - GES., 7, Stadtbachstrasse, Augsburg, Germany. July 24, 1931, No. 21256. Convention date, July 26, 1930. '[Class 7 (v).] For the remote control of internal-combustion engines, e.g. from the captain's bridge on board ship, the controls for starting, stopping, and reversing and for fuel regulation are duplicated, one set being mounted on the engine and the other set at the remote control point, the two sets being interconnected so as to be operable simultaneously or independently. As shown in Fig. 1, the engine a is provided with a starting-air valve b, a reversing valve c and a fuel-pump regulating device d controlled respectively by levers b<1>, cl and a hand-wheel d<1>. The starting valve b is connected by a pipe b<3> to the cylinders ; the reversing valve is connected to a compressed-air reversing cylinder e in which is a piston for effecting the adjustment of the cam shaft ; and the fuel pump may be controlled by the starting lever b<1>, in the " stop " position of which the pump is rendered inoperative. The levers b<1>, c<1> are connected to corresponding levers B<1>, C<1> on the captain's bridge by rods, links &c. f .. i, and the handwheel d<1> is connected to a hand-wheel D<1> on the bridge by shafts l and bevel gearing. To enable the levers b<1>, c<1> on the engine to be used when the levers B<1>, C<1> on the bridge are locked, a disconnectible coupling is provided in each of the rods f, g. The rod g, Fig. 3, is in two telescopic parts g<1>, g<2> connected by means of a sleeve p mounted on a collar o of the rod g<1> and provided with cheeks p<2>, and the rod g<2> is provided with a disc g<3> having two straight edges g<4>. As shown in Fig. 4, the cheeks p<2> lie over the disc g3 and couple the rods ; on turning the sleeve p through 90‹ by means of an arm p<1>, the cheeks p<2> are slidable over the straight edges g4, allowing independent movement of the rod g<2>. In a modification, the starting-air valves and the reversing valves are connected to the compressed-air supply by a change-over cock so that.either the valves on the engine or those on the bridge may be used. The reversing valves c, C are connected by a second changeover cock to the reversing cylinder for the adjustment.of the valve gear, and both changeover cocks are actuated by hand-wheels on the bridge. The starting-valves are connected by a pipe t, Fig. 8, to the cylinder u of a shut-off device for the fuel pump ; on opening either starting valve, the compressed air admitted to the cylinder u lifts a piston u<1> and actuates an arm v on a shaft w in order to open an overflow valve putting the pump out of action. The fuel pump may be put out of action from the bridge, independently of the starting valve, by a compressed-air valve connected to the pipe t. Electric or hydraulic connections may be employed in place of the mechanical and compressed-air connections described.

Title: An improved file grinding machine
IPC: B24B3/60
Filed: 1921-08-10
Abstract: 188,739. K³ndig, G. Aug. 10, 1921. No Patent granted (Sealing fee not paid). Disc apparatus; files, treating.-A file-grinding machine having a vertically adjustable work-table 3 slidable on a frame 1 is characterized by the feature that the work-table, the weight of which is approximately balanced by a weight 9, carries a balance weight 20 for pressing the work against a grinding-wheel 11, which remains at a constant height, the table being provided with a device causing it to descend as the grinding-wheel wears away. An upright 4 attached to the table 3 is connected to the weight 9 by ropes and pulleys 6, 8. The table 3 is slotted to surround the wheel 11 and carries guides 14, wherein a workholder is reciprocated; the guides carry bearings 16 for a crank-shaft 17. On the pin of crankshaft 17 is pivoted a beam 18, which carries the slidable weight 20 and is slotted to engage a bolt 26 of a fork 23 embracing a pressure-roller 24 adapted to engage the top of the work-holder. As the grinding-wheel 11 is at a constant height, the beam 18 acts as a lever fulcrumed at 26 to lift the table 3 till a stop 43 thereon engages the lower surface of the file. The position of the shaft 17 is adjusted by a lever 22 moving over a sector 21. The pressure between the work and the grinding-wheel is due to the unbalanced weight of the table, which is determined by the position of a weight on a lever exerting a torque upon a ratchet-wheel 34 geared by bevel-wheels 38, 39 to a pinion 41 carried by the table and engaging a fixed rack 42. As the grinding-wheel wears away, the unbalanced weight of the table causes the table to descend. In order that this descent shall not occur during the reversal of movement of the work-holder, a band-brake 31 on the same shaft as the ratchet-wheel 34 is operated by a tension member 30 secured to the end of a rod 29 connected to the reversing- mechanism of the work-holder. The rod 29 has an upwardly concave slot 44 engaging a fixed pin 45 so that, when the rod 29 is at either of its end positions, the member 30 is slack, but when the machine is stationary and the rod 29 occupies a mid-position, the member is taut, thus preventing downward movement of the table.

Title: Process and apparatus for preparing synthetic filamentary structures
IPC: B29C48/05
Filed: 1965-05-21
Abstract: 1,090,478. Synthetic filaments. MONSANTO CO. May 21, 1965 [May 21, 1964; July 27, 1964], No. 21641/65. Heading B5B. [Also in Division D2] Continuous synthetic filaments suitable for paper-making and other non-woven products are comprised of a multitude of loosely bonded fibrils having highly porous cross-sections, said pores comprising greater than 50% of the area thereof. Such filaments which are preferably of 40-80 deniers, may be made by preparing a slurry comprised of acrylonitrile based polymer dispersed in an aqueous solution containing a water soluble cellulose derivative, heating the slurry under pressure to convert same into a " viscous melt ", (actually a two-phase watermelt system) extruding the viscous melt through a plurality of orifices into a restricted area, and directing a high velocity stream of steam transversely against the extruded melt to form filaments. Preferably a slurry based on a polymer comprising at least 80% acrylonitrile, 0-10% vinyl acetate and 0-10% of at least one other unsaturated monomeric compound. copolymerizable therewith (styrene is preferred but many others are listed) is heated to 130-150 C., in a first heating zone, advanced through a second heating zone in which it is heated to 150-205 C. to form the " viscous melt ", the melt extruded horizontally and the high velocity stream of steam directed vertically downward against the extruded melt to form continuous filaments having crosssections characterized by cavities and fissures. Desirably, the polymers are comprised of 93% acrylonitrile and 7% vinyl acetate, the cellulose derivative is sodium carboxymethyl cellulose the slurry has 2-30% polymer solids, and the sodium carboxymethyl cellulose comprises 6- 18% of the polymer solids. In the apparatus of Fig. 1, the slurry, heated under pressure, passes through pipe 26 and spinneret plate 20, which has a plurality of obliquely-drilled orifices (Fig. 2, not reproduced) into the passage 19 where it meets a jet of steam entering at 30. The steam assists the flashing of the water contained in the slurry, and the filamentary structures formed, which pass through the restricted passage 16, have the form described above, and shown in Fig. 6 (not reproduced). Fig. 3 shows an alternative form of apparatus. The polymer composition is supplied via 43 to the chamber 42 and passes through obliquely-drilled holes 50 in the tubular spinneret 44 toits interior, where the extruded melt meets a jet of steam supplied via 54. The filaments pass through the restricted passage 58 and their form is similar to those obtained using the apparatus of Fig. 1. Paper may be made by collecting the tow, cutting into half-inch staple lengths, slurrying with water and beating. When sufficient fibrillation has occurred the sample is transferred to a sheeting machine. A soft batt may be made by subjecting the cut staple to a longitudinal scraping action, e.g. by carding to develop a fibrillous batt which can be matted to make a soft batt.

Title: Digital echo suppressor
IPC: H04M9/10
Filed: 1975-05-21
Abstract: 1495638 Digital echo suppressors COMMUNICATIONS SATELLITE CORP 21 May 1975 [13 June 1974] 21704/75 Heading H4R In a digital echo suppressor signals from the send and receive lines are formed 10-18 into a train of digital signals consisting of alternate samples from the lines and bearing a sign appropriate to the transmission direction (here "receive" is positive), a first adder 20 accumulates the sum over repetitive fixed time periods of the receive line signals and when this exceeds a threshold a suppression circuit 29 opens a send switch 31, whilst a second adder 21 accumulates the sum of both the send and receive line signals over the same repetitive time periods, a store 36 contains the signs of the last N summations, and a break-in circuit 49 determines when a predetermined number (e.g. half or more) of the stored signs relate to the send direction so as to operate a switch 51 overriding the send switch 31 when that switch is operative. The suppression and break-in circuits 29, 49 respectively persist for 50 ms. and 150 ms. after triggering. Additionally, a 6 dB attenuation pad 35 may be inserted in the receive line by a circuit 52 having a hangover of 600 ms. equivalent to the time taken to receive an echo of the send signal over the transmission link. The digital encoding is performed by first alternately gating the send and receive signals by a multiplexer 12 during the negative and positive half cycles respectively of an 8 kHz square wave clock on line 60. Sample-and-hold circuit 12 and A/D converter 14 precede logic circuits 16, 18 (detailed in Fig. 2, not shown) which ensure that the output code train to the adders consists of amplitude bits preceded by either a negative sign bit for the send signals or a positive sign bit for the receive signals as appropriate, the data being in two's-complement code. Latches 26, 27 in the adding circuits 20, 21 are advanced at 8 kHz and 16 kHz respectively over lines 55, 56 to perform their respective addition functions and are reset every 4 ms. over line 28. Similarly, a counter 45 for the signs of the send codes emanating via gate 40 from the store 36 is reset every 4 ms. and provides an output to gate 46 over line 44 when half of the stored signs correspond to send signals. The suppressor may be time shared between plural transmission links.
