Title: Linear vibrator
Inventor: LEE KYOUNG-HO
IPC: B06B1/04
Filed: 2009-12-30
Abstract: A linear vibrator comprises a base. 102; a coil unit (fig 2, 130) coupled to the base; a magnet (fig 2, 200) that can move relatively to the base; and plural leaf springs 400 between the magnet and base that face one another and are coupled to one another. Leaf spring 400 can comprise rectangular frames (fig 9, 410a,b) and second frames (fig 9, 430a,b) and spiral. plate-shaped members (fig 9, 420a,b) facing one another. that are coupled. The leaf springs can be coupled either at the second frames or at the rectangular frames (fig 10) and deform in the same direction. The magnet can move horizontally and be inserted into the hollow coil unit, which can be supported by a bobbin and is coupled to the base. The vibrator can further comprise a weight (fig 2, 950) coupled to the magnet, a yoke (fig 2, 310) surrounding the magnet and a circuit substrate (fig 2, 120). The vibrator can be used in a mobile phone to generate a vibration when an LCD touch-screen is touched.

Title: Dispenser for viscous liquids
Inventor: DEADMAN LIONEL LESLIE FREDERIC
IPC: B43K7/00
Filed: 1956-03-29
Abstract: <PICT:0809037/III/1> <PICT:0809037/III/2> A dispenser for viscous liquids such as cosmetics comprises an elongated tubular body which houses a reservoir for the liquid, a rotatable ball retained in a housing at one end of the body and projecting outwardly of the body so as to apply a narrow film of liquid to a surface when drawn thereover, an air passage passing through the body and communicating with the reservoir, a cap which may be fitted over either end of the body, and means for urging the liquid towards the ball by movement of the cap.  As shown (Figs. 1 and 2) a body 1 houses a tube 2 containing a viscous marking liquid and having a ball 4 rotatably mounted at one end. The end of the body remote from the ball is closed by a plug 9 having a passage 10 through it.  The space between the top of the viscous liquid and the plug 9 is filled by a gel-like material 11 immiscible with the liquid.  A movable sealing ring 12 is mounted on a part 13 of the body of reduced diameter and two air channels are provided from the outside of the part of the body between 9 and 13 to the narrow part, which channels are closed when the ring is against abutment 15 but open when the ring is against abutment 14.  The construction is such that removing the cap from the ball end of the body sucks the liquid towards the ball, and placing it on the other end urges liquid towards the ball; but during the reverse process air pressures are equalized through channels 16 so that at no time is the liquid urged away from the ball.  In alternative constructions (1) a passage from the interior to the outside of the body 1 is provided through the channels instead of through the cap 9; (2) the tube 2 is dispensed with.

Abstract: 141,383. Punga, F. March 26, 1919, [Convention date]. Alternating-current motors; armatures, cooling. -In induction motors having a starting winding b and a running winding a, which is short-circuited by a switching device, increased magnetic flux leakage is obtained by placing the bars of the winding b in a smaller number of slots than is employed for the winding a, and either in separate slots or in some of the slots containing the running winding. In larger machines, a starting lever l is employed, giving in succession star and delta connexions to the stator, and short-circuiting the rotor running winding by means of the contact d. The slots which do not contain the starting winding b can be used for ventilation. The Specification as open to inspection under Sect. 91 (3) (a) states that the starting winding may be located in all the slots, some having only a very small portion, whereas the others contain the major portion.

Title: Devices for measuring electrical impedances
IPC: G01R27/02
Filed: 1944-05-26
Abstract: 576,903. Inductance, capacitance, and resistance measurements. STANDARD TELEPHONES & CABLES, Ltd. May 26, 1944, No. 10233. Convention date, June 8, 1943. [Class 37] An impedance measuring device compri a source of alternating test signals adapted to be connected to two resistive impedances in series, a reactive impedance connected in parallel with each resistance and an oscillograph adapted to be connected across one of the impedances. One of the impedances is the unknown and another is varied until the device is balanced, as indicated by the oscillograph. The test voltage is applied at terminals 1, 2 to known resistances R, R1 in series, shunted respectively by impedances CX, C1 of which CX is the unknown and C1 a known variable capacitor. The input voltage has a steep fronted waveform, e.g., as shown in Fig. 3, and in use C1 is adjusted to effect balance, when the device operates as a balanced attenuator, and R/R1 = CX/C1 + C3, the value C3 being the distributed capacity of the wiring and input to a cathode ray oscillograph 20 connected across C1. Balance is obtained when the waveform indicated on the C.R.T. is identical with that of the input, unbalance giving distorted waveforms of a shape dependent on whether the reactance of C1 is too large or small. One of the resistances R, R1 may be variable and resistances may be measured by substituting the unknown ressistance in place of R or R1 and effecting balance by means of known capacitors in place of CX, C1. Similarly, to measure inductance the unknown would replace CX or C1 and the device balanced by a variable inductance in place of the other capacitor CX or C1.

Suitable gases are ethylene, acetylene and nitrous oxide : suitable vapours are carbon bisulphide and mercaptans. In making the cable, the porous material and insulating fluid are first degasefied and the insulated conductors are then immersed in the fluid, preferably hot, and the gas introduced, after a suitable interval, above the surface of the fluid: the cable is then cooled under pressure and sheathed. Alternatively the insulation and impregnating fluid are separately impregnated with gas and degasefied, after which fluid impregnation is effected.
