Title: Person tracking and location system
Inventor: ROUND CHRISTINE MARY
IPC: G01S5/00
Filed: 2009-11-18
Abstract: A method of tracking a person's location is described. The system utilises a mobile wireless data packet protocol, such as the General Packet Radio System (GPRS) wireless protocol to transfer user location information to an Internet based location server. This provides wide area location tracking and alleviates the need for a voice channel and associated electronic circuits. A wearable wireless transceiver unit 1 also incorporates a short-range wireless transceiver to communicate with a movable base station (figure 5, 1B). Disruption to this link automatically issues an alarm signal to authorized users via the mobile network link. Location information is gathered automatically at a user selectable rate and is accessible to authorized users on demand and can be overlaid on a displayed map. A user can also manually activate an alarm in case of an emergency and notify one or a plurality of authorized users. The wearable transceiver could be worn by a child and the mobile receiver could be held by a parent or an authorized carer.

Title: Improvements in or relating to the cold extrusion of steel
IPC: B21C23/03
Filed: 1952-04-22
Abstract: 727,670. Making cupped articles and hollow-ware. MULLINS MANUFAC. TURING CORPORATION. April 22, 1952 [April 23, 1951], No. 10072/52. Class 83 (2) and 83 (4). Forging; extruding.-In the first step of cold working a solid steel blank to form a cup-shaped or hollow article a blank 1 cut from a rolled bar is worked by a punch 12 in a die 2, Fig. 2, which laterally expands the blank and forms it with an upper tapered recess 20, a lower tapered projection 26 and tapered side and bottom walls 24, 25. The blank so formed is also accurately trued. In the second step the blank is compressed in a die 28, Fig. 3, with a series of cylindrical and tapered inner surfaces between a punch 41 and a support member 38 which also forms an ejector. The punch enters the blank so that a tapered end 49 forms a cup from the projection 26, displaced metal being rearwardly extruded between the punch and die to form a cupshaped blank 52, Fig. 11, with a secondary cup 54 projecting from the bottom. After this operation the work is annealed. The bottom of the blank is then further worked, firstly to deepen the secondary cup and to form a raised ridge 101 of metal at the junction of the secondary cup 96 and the bottom wall 98 of the primary cup 95, Fig. 12, and secondly to round the bottom of the primary cup and to further elongate the secondary cup by a slight extrusion as shown in Fig. 6. The bottom 127 of the secondary cup is next heavily compressed between the bottom of a punch and an anvil to eliminate grain-flow lines and produce granular fusion, 'thus giving a dense structure. The relatively thick upper part 122 of the wall of the blank is then elongated by direct extrusion by a punch 166 in a die 157, Fig. 8, the bottom 148 not being further worked. Gas pressure is relieved by a passage 177 through the punch. A tapered portion 169 of the punch co-operates with the extrusion orifice 162 of the die to thin the upper end 176 of the walls of the blank. The outwardly curved upper edge 174 is subsequently drawn and trimmed to form the blank shown in Fig. 14. In order to form a pressure container, Fig. 15, this edge is swaged to form a curved end 181 with a central projecting neck 182.

Title: An apparatus for making feather yarn
IPC: D02G3/42
Filed: 1921-04-06
Abstract: 180,502. Ohashi, R. April 6, 1921. Chenille.-In making feather yarn, feathers are fed so that their quill parts enter from the front of the apparatus shown between a pair of separated rotating cutters 3 coacting with a geared rotary member 6, the severed barb parts of the feathers being caught between pairs of rubber-covered rollers 5, 7 and between pairs of threads from spools 13, 13<1>. The free ends of the pairs of threads are secured to bobbins 19 mounted on a carriage 18. While the rollers are rotating to feed the severed barbs and the yarns, the carriage 18 is moved rearwards by a chain 22 secured at its ends thereto and passing around a wheel 25 on the front part of the apparatus and around wheels 11, 21, the bobbins 19 being rotated, to twist the yarns, by a guided rope 23 driven by a pulley 9 on the shaft 2, which is driven by a pulley 10 and is geared to the shaft 1. When the carriage reaches the end of its travel, the machine is stopped, and, on pulling one side of a rope 24, a pivoted frame 17 on the carriage 18 is tilted to guide the twisted feather yarn on to the bobbins 19. The carriage is then driven forwards by pulling the rope as a whole, and the bobbins are rotated to wind the yarn, the pulley 9 being rotated by the chain. The sequence, of operations is then repeated.

Title: Improvements in or relating to depth charges
IPC: F42C5/00
Filed: 1928-04-04
Abstract: 288,304. Aktiebolaget Lindholmen- Motala. April 5, 1927, [Convention date]. Projectile fuzes. - Relates to hvdrostatically operated depth-charges, and consists mainly in means for holding the primer to the hydrostatic device until the appointed depth is reached, when the primer is released and moves towards the pistol which fires it. As shown in Fig. 1, the depth charge comprises a cylindrical casing 1 closed by dished covers 2, 3 connected by a central tube 6 containing at one end the pistol 9 and at the other end the primer 26, which is attached to the hydrostatic device 31 secured to the depth charge by a strap 55 and tightening screw 56. As shown in Fig. 2, the hydrostatic device has a chamber 31 separated by a diaphragm 34 from a second chamber 32, to which the primer 26 is attached by a ball catch 60. The diaphragm 34 is connected to a lever 37 balanced by a plunger 40 controlled by springs 41, 42, the spring 41 being a weak one for small depths and the spring 42 a stiffer one for greater depths. The upper end of the plunger 40 fits into a valve 46, which can be rotated bv an external handle 50 and transmits rotation by keys 47 to an abutment sleeve 48 for the spring 42. This sleeve has a spiral thread 44 engaged by fixed pins 45, and when rotated by the valve is displaced longitudinally to vary the pressure of the spring 42. When the valve is in the closed position, the plunger 40 is locked by a pawl 51: but when the valve is turned to open the ports admitting water into the chamber 31 the sleeve 43 deflects the pawl 51, thereby releasing the plunger 40. The amount of rotation of the valve determines the pressure of the springs on the plunger 40 and thus the depth at which the hydrostatic diaphragm 34 will operate, and this depth is indicated by a pointer on the handle 50 and by a clicking spring stud 54 in the handle 50. When the diaphragm 34 is depressed by the water pressure, a stem 33 attached thereto depresses a sleeve 63 against a spring 64 and liberates the ball catch 6C, releasing the primer 26. Water pressure admitted by ports 57, 58 then moves the primer 26 towards the pistol; a recess 28 in the primer embraces the detonator 12; the end 67 of the primer deflects catches 25, 22, Fig. 4, thereby unlocking the parts 10. 9 of the pistol from each other; and the face 27 of the primer 26 comes to bear on the face 11, Fig. 3, of the pistol and forces the part 10 into the part 9 against a spring 15. A stem 21 displaces a sleeve 18 against a spring 19, liberating a ball catch 16, releasing the striker 14, which fires the detorator 12 under the influence of the spring 15. The catches 25, 22 and the lever device 37 are so balanced as to be unaffected by shocks, which otherwise might cause accidental firing. The ports admitting water to the chamber 31 are made small to avoid sympathetic explosion ef the depth charge when an explosion occurs near it.

April 4, 1934, No. 10199. [Class 51 (ii)] In a charging apparatus for horizontal coke ovens comprising a travelling carriage 2 with a number of coal hoppers 1 having beneath their outlets 5 vertically movable sleeves 7, which can be lowered simultaneously on to the oven top by operation of a lever 18 in the driving-cab 6, arrangements are provided by which any one of the sleeves can be lifted and maintained in its raised position independently of the others, and of the main control lever. In the construction shown, the sleeve 7 is carried by a three-armed counterweighted lever 8, 10, 12 operated from the driving-cab lever 18 through links 15, 17. The lower end of the link 15 is slotted, and a pin 13 on the arm 12 is normally positioned, in an end recess 19 of the slot 14. When it is desired to raise the sleeve independently of the main control 18 the link 15 is lifted by the link 20, bell-crank 21 and operating-rod 23, to allow the pin 13 to move from the recess 19 into the slot 14, and the counterweight 11 to raise the sleeve. The next operation of the lever 18 re-positions the pin in the recess. A modified form of mechanism is described in which the hopper control slide is interconnected with the sleeve-lowering device.

Abstract: 454,569. Echo-sounding and distancemeasuring apparatus. HUGHES & SON, Ltd., H., 59, Fenchurch Street, and SPROULE, D. O., 21, Albemarle Street, Piccadilly, both in London. April 2, 1935, No. 10225. [Class 118 (ii)] An indicator for echo-sounding apparatus comprises a number of reeds adjacent a scale and a moving magnet which is energized by the incoming signal and sets the reeds in vibration. As shown in the Figure, the magnet h rotates in timed relation to the transmitted pulses and is energized by both transmitted and received pulses. When the magnet is energized the reeds b adjacent the poles of the magnet vibrate so that indications such as those at wand x are given. The magnet also responds to sea noises but as the indications given are usually of irregular form as shown at y instead of the regular form of w and x and appear at different places on the scale in each cycle, the echo indication can be distinguished. The scale may be marked directly in fathoms.

Title: Control mechanism
IPC: B63H21/22
Filed: 1975-03-13
Abstract: 1487657 Clutch and throttle control; linkwork NIPPON CABLE SYSTEM Inc 13 March 1975 [26 July 1974 12 Oct 1974] 10434/75 Headings F2L F2D and F2K  A control mechanism for the conjoint operation of an engine throttle and a clutch comprises a lever 1 which is moved to rotate a throttle operating member 7 which in turn operates the throttle through a Bowden mechanism 5, the throttle operating member 7 having gear teeth 11 which rotate a gear 14 having at least one untoothed portion a, b, this gear rotating a clutch operating member 8 by engagement with teeth 13 therein, the clutch operating member 8 operating a clutch actuating Bowden mechanism 6. The direction of movement of the clutch operating member 8, and so of the inner cable 17 of the Bowden mechanism 6, from the position shown, also determines the direction of movement of a boat in which the mechanism is provided. The gear teeth 11 of throttle operating member 7 extend over only the central portion of an aperture 10 so that on rotation of lever 1 the gear 14 is rotated until its untoothed portion a or b contacts the untoothed portion of surface 10<SP>1</SP> of aperture 10, and the gear 14 is thus held stationary, with the clutch operating member 8 held stationary with the clutch engaged, whilst further movement of lever 1 increases the engine speed by pulling throttle cable 16. In order to prevent any increase of engine speed until the clutch is engaged a cam plate 25 having a cam slot 26 can be provided, the throttle control member 7 being pivoted to end connector 18 and so to a rod 16<SP>1</SP> joined to the cable 16 of the Bowden mechanism 6, the rod 16<SP>1</SP> and an enclosing tube 36 being within a pivoted member 28, which has lugs 29 on each side of tube 36. The pivoted member 28 has a pin 45 which moves in the cam slot 26 and the arrangement is such that the outer conduit 50 of the Bowden mechanism, which conduit is secured to a plate 33 pivotably mounted on member 28, moves with the inner members 16<SP>1</SP>, 16 until the throttle control plate 7 has rotated to bring pin 45 to position T or position U of cam slot 26 and only after this does further rotation of member 7 increase engine speed, at which time the drive engaging clutch is engaged. Fine control of engine speed is possible by pivoting a lever 48 to which a cam plate 37 having a slot 38 is connected, this cam plate causing a plate 39 to move, by engagement of a pin 40 in the slot 38, and this plate in turn moving the cam plate 25 in a direction G to move the outer conduit 50 in direction G, which increases engine speed. The cam plate 25 has lugs 43 engaging in slots 44 to guide it for this movement. In an alternative embodiment (Figs. 4 to 7, not shown) two gears on a shaft are employed in place of gear 14, these giving an increase of ratio being the throttle and clutch control members, and these gears-can be disengaged from the control members to allow the engine to be warmed up without engaging the clutch.
