Title: Wet sieving
IPC: G01N15/02
Filed: 1973-01-04
Abstract: 1357310 Determining particle size by weighing CHAMBER OF MINES SERVICES PTY Ltd 4 Jan 1973 [11 Jan 1972] 605/73 Heading G1S Particles to be sized are made into a slurry which is piped into a vessel A to a level L on top of water already filled to the level of a screen S. Let this weight of water and slurry be WB. A valve V is then opened and water piped from W to wash fine particles from the slurry through the screen until clear water issues from valve V. The valve is then closed and water added to level L. The vessel is then weighed with the water and solids left on the screen. Let this weight be WA. If the weight of water alone to level L is WW , and the weight of the slurry on top of the water is WB, then the total weight of solids in the slurry added initially to the vessel is given by WB-WW divided by 1-pw/ps, where pw and ps are the S G's of water and solids to be sized respectively. Similarly, the weight of solids remaining after washing out the fine material is given by WA -WW divided by WB-WW. On completion of sieving and weighing a sample the solids left on the screen may be washed away through valve X.

Title: Apparatus and method for obtaining the performance of a wind propelled vessel
IPC: G01P5/06
Filed: 1974-01-07
Abstract: 1484351 Navigation apparatus; measuring fluid-flow R M J O K HAFNER 6 Jan 1975 [7 Jan 1974]  676/74 Headings G1F and G1R An apparatus comprises means for determining the mean speeds of and distances travelled by a vessel over a period of time relative to the sea and to the wind and for detecting any divergence between the mean apparent wind direction and the heading direction of the vessel. A wind vane 27 is mounted on a support whose orientation relative to the vessel mast head 30 can be adjusted by means of cables 31. The vane can pivot over a limited range on either side of a mean position dependent on the orientation of the support, and the amount of displacement of the vane from the mean position is integrated or accumulated over a period of time and displayed on an indicator (not shown), having a range on either side of a zero point to show the orientation of the support with respect to the wind direction. The vane 27 may comprise two contacts 29 which effect electric connections at the ends of the range to drive a reversible motor and pointer to provide the indication; the motor may be fed via an operational amplifier (43), Fig. 7 (not shown); alternatively the vane may be connected to a potentiometer (37), Fig. 6 (not shown), in a bridge circuit (38) comprising a heavily damped indicator (40); alternatively the vane may carry a photo-cell (34) Figs. 9A, 9B (not shown), illuminated by a fixed LED (32) and separated by slotted screens (35). In use, the support is set so that the mean position is in the direction of the required apparent wind direction and the heading of the vessel is adjusted to eliminate any mean departure of the vane from the mean position. Wind and water speeds are determined by a rotor 47 and a log 20 which produce respective pulses, in the case of rotor 47 by a flat rotating screen 50, Fig. 10A, between an LED 48 and a photo-cell 49, and in the case of the log by a rotating star-shape screen 52, Fig. 11A, between an LED 53 and a photo-cell 54, the pulses being indicated on counters (15, 16) Fig. 8 (not shown); a switch (17) and timer (18) in circuit with the counters stop the counters at a predetermined time or count. Leeway is indicated by a pointer 26 attached to a pivoted housing 24 trailing the log.

Title: Improvements in and relating to weighing scales
IPC: G01G21/00
Filed: 1935-01-08
Abstract: 429,990. Weighing-apparatus. JENNINGS, H. W. K., 51, Chancery Lane, London. -(Jacobs Bros. Co., Inc. ; 28, Washington Street, Brooklyn, New York, U.S.A.) Jan. 8, 1935, No. 685. [Class 143] [See also Group XXII] In a platform weighing-machine the levers are made of strip steel or the like and the fulcra of the levers are constituted by the edges of the strips. The levers 31, 41 are of T-shape and V-shape respectively and are bent and twisted as shown so that the fulcra 33 are formed by the corners of the strip. The side frames 10 are notched to receive the fulcra and are formed of two identical channelled stampings abutting at the point 19. The lever 41 carries a channel element 43, secured by spot-welding. A bent rod 45 pivotally connects the element 43 to the lever 31. The platform 55 carries depending strips or legs which are notched to rest upon the upturned corners of the twisted portions 35, 39 of the levers, a spring tongue 62 (struck out of the platform) preventing accidental removal of the platform. The lever 31 is connected to a weighing spring 48 suspended from a column 20 by a spiral washer, screw 50 and adjusting nut 51. An indicating drum 28 is actuated by a rack 53 resting in a depression in the end of the lever 31.

Patent GB-898220-A (GB)
Title: Improvements in self-regulating reciprocating pumps
IPC: F04B49/16
Filed: 1959-01-08
Abstract: 898,220. Fuel injection pumps. BESSIERE, P. E. Jan. 8, 1959 [Jan. 21, 1958], No. 786/59. Class 102(1). A fuel injection pump in which a piston 1, driven at a speed proportional to the engine, hydraulically actuates a piston 2 which pumps fuel from the pump chamber 7 to the delivery line 9, the end of the delivery stroke of the piston 2 being determined by a by-pass conduit 13. A third piston 23 integral with the piston 1 delivers liquid past valve 20 to conduit 19 closing the valve 14 in the pump chamber feed conduit 8 during the delivery stroke and also closes a valve 28 in a conduit 21 by liquid delivered through a conduit 29. In operation at the commencement of the delivery stroke of piston 1 the space between the pistons 1 and 2 has been filled with liquid from inlet 6 so that the delivery stroke of piston 2 starts when piston 1 closes the inlet 6, at the same time the valves 14 and 28 are closed by the delivery of piston 23, a notch 32 allowing escape of excess liquid delivered by piston 28. As the piston 1 and 23 commence their suction stroke, valve 28 immediately opens and the liquid acting on valve 14 starts to escape through conduit 19, 21 and throttle 26, thus the opening of valve 14 is delayed and piston 2 under the action of friction or a light spring 12 remains in its upper position until the conduit 8 is opened by the valve 14 and fuel under pressure flows into the pump chamber 7 causing the return of piston 2. When the speed of piston 1 increases above a predetermined value the piston 2 does not complete its return stroke before the piston 1 again actuates the piston and therefore the stroke of the piston 2 and the quantity of fuel delivered is reduced. In a modification the throttle 26 may be replaced by a throttle in the feed conduit 8, thus allowing the valve 14 to open immediately, the throttle controlling the rate of flow to pump chamber 7.

Title: Improvements in or relating to double-twist spindles
IPC: D01H7/86
Filed: 1950-01-12
Abstract: 681,562. Double-twist spindles. COMPTOIR DES TEXTILES ARTIFICIELS. Jan. 12, 1950 [Jan. 12, 1949], No. 842/50. Class 120(ii) Double twist spindles have the yarn package support freely mounted for rotation on a spindle shaft and carrying a circular permanent magnet incorporating a pair of upper and lower annular armatures each having a plurality of outwardly projecting pole pieces equally circumferentially spaced to co-act with a plurality of spaced curve plates of magnetic material recessed in a non- magnetic outer bowl-shaped annular member whose lower part is provided with a rotatable metal cupshaped cover, said spaced curve plates being so disposed as to complete a magnetic circuit to hold the said support stationary, said magnetic circuit including an air gap for passage of the yarn. As shown the cup member 26 carrying the magnet 43 having three projecting poles 45 spaced 120 degrees apart is secured to a sleeve 22 of synthetic resin or other non-magnetic material by rubber rings 28 and 29. The sleeve 22 is mounted on bearings 13 and 14 on a hollow tubular member 12 which is joined to the spindle shaft 5 by a conical tube 15 shrunk on to the upper end of 5 and the lower end of 12. A disc 16 carrying a steel ring 17, faced with chromium, is carried on the conical tube 15. The generally radial holes 19 pass through the disc 16 and tube 15 and register with the space between the flared lower end of tubular member 12 and the flared point 18 of the upper end of shaft 5. The lower end of shaft 5 receives the pointed end of a pin 6 carried by the support member 9 and the upper end of shaft 5 is supported by a roller bearing 11 also carried by support 9. A bowl-shaped member 46, made of synthetic resin or other non-magnetic material, is fixed to the support member 9 and has six equi-spaced thin rectangular soft iron plates 48 embedded in it, these plates co-operate with magnet 43 to hold the cup 26 and the yarn package 34 thereon against rotation when the spindle shaft 5 is rotated. The support 9 also carries a shallow sheet metal cup 50 which can be turned slightly relatively to the support. The member 46 receives three equi-spaced pins 51 which project downwardly and enter pockets 52 formed in the bottom of the cup 50. These pockets have sloping surfaces so that on rotation of the cup 50 the pins are raised against springs 54, Fig. 5, and engage the disc 16 and hold it against rotation. In use, yarn passes from the package 34 over the polished top of cone 35, down inside the cone 35, through a ball tensioning device 31, 32 into the hollow tubular member 12, out through the radial holes 19 in disc 16 and up between the magnet poles and the bowl-shaped member to the thread guide 56.

Title: Process for machinable lead-free wrought copper-based alloys
Inventor: LOLACONO DOMINIC N
IPC: C22C9/00
Filed: 1997-06-05
Abstract: Lead inclusion in copper-containing wrought alloys is coming into disfavor due to health and environmental considerations. Machinability, as well as retention of workability properties, associated with lead inclusion are assured by bismuth together with a modifying element, phosphorus, indium or tin. The modifying element minimizes the workability-precluding embrittlement otherwise caused by bismuth. The alloys are essentially of a stoichiometry and content of prototypical lead-containing alloy as specified as CDA 100-700 series wrought alloys in the 8th edition of the CDA Handbook of Wrought Products except that lead is replaced by bismuth within the weight percent range of 0.5-2 and that such composition invariably contains at least one of the third element additions in the weight percent ranges indicated; 0.1-0.5 P, 0.25-1.0 In, 0.5-6.0 Sn.

Title: Resin sealing method for semiconductor chip
Inventor: YOSHIYAMA TAKAYUKI
IPC: H01L21/56
Filed: 1995-01-05
Abstract: PURPOSE: To avoid the short-circuit accident caused by upside-down standing and the like by applying a small amount of reinforcing resin less than sealing resin before the application of a large amount of the sealing resin to be in contact with a piece of wire, thereby reinforcing the exposed weak wire, and making the wire hard to be deformed. CONSTITUTION: Reinforcing resin 8 is applied to be in contact with a piece of wire 6 so as to surround a semiconductor chip 3 by on round in the vicinity of an electrode 2 by a dispenser 7, which discharges the reinforcing resin 8. Then, a substrate 1 is cured, and the reinforcing resin 8 is hardened. As a result, the substantial strength of the wire 6 is increased by the reinforcing resin 8, and the wire 6 becomes hard to be deformed. After the wire 6 is reinforced, sealing resin 10 is applied so as to coat the semiconductor chip 3, the wire 6 and the reinforcing resin 8. The curing is performed again, and the sealing resin 10 is hardened. Thus, the sealing is completed. At this time, since the wires 6 are already reinforced, the wires 6 are not short-circuited to each other by the flowing of the sealing resin 10.
