IPC: B65D65/28
Filed: 1997-08-07
Abstract: Flexible plastic bag for a plurality of compressible absorbent articles which are arranged in parallel, one beside the other. The bag has an approximately rectangular base, a front side, a rear side, two narrow sides, and an upper side and is closed on all sides. The bag also has a line of weakness which marks an opening for the individual removal of the articles. The height of the bag is greater than the depth of the bag, the line of weakness extends, midway along the bag, from the longitudinal center of the upper side, toward the base, about half way down the front side of the bag. The base has a downwardly directed supporting band. The absorbent articles do not exerting sufficient pressure on any of the sides of the bag filled with said articles to cause the opening to gape open. The opening can be formed by bending the bag to open the line of weakness, and it closes after removal of the product when the bag is replaced on its supporting edge. Thus, the bag provides a substantial hygienic storage of absorbent products.

R. ; R.F.D.1, Schenectady, New York, U.S.A.) Jan. 13, 1933, No. 1206. Convention date, Jan. 13, 1932. [Class 37.] The moisture content of a material is determined by bringing the material into proximity with the electrodes of a condenses connected to a source of high-frequency currents, and determining the dielectric losses due to the presence of moisture in the material. In one arrangement, Fig. 1, a continuously moving strip 11 of material, e.g. paper, passes over a pair of plates 12, forming a condenser, connected in the secondary circuit of a transformer 14 supplied with high-frequency oscillations from a tube oscillator 13. The frequency of the circuit is stabilized at a desired valve by means of a condenser 15. The increase in the output of the oscillator due to the dielectric losses in the strip 11 is a measure of the moisture content, and may be determined by a watt-meter 19, wich may be of the type described in Specification 392,438. An ammeter 18 may also be included in the circuit. Contact-making devices which serve to control apparatus for regulating the moisture content of the material 11 may replace the instrument 19. In a modified arrangement, Fig. 2, for measuring the moisture content of a material in bulk, the material 20 is placed in a vessel 21 of conducting material which forms one electrode of the condenser, the other electrode being formed by an insulated plate 22. Specification 275,741, [Class 37], also is referred to.

Title: Improvements relating to radio locating and/or indicating systems and apparatus therefor
IPC: G01S13/42
Filed: 1945-01-15
Abstract: 634,075. Radiolocation. SPERRY GYROSCOPE CO., Inc. Jan. 15, 1945, No. 1230. Convention date, Jan. 14, 1944. [Class 40 (vii)] In a pulse radar system, comprising a conically scanning, directive aerial system, and transmitting pulses when the aerial lobe passes through four equally spaced positions in its orbit, the received echo signals are displayed upon two cathode-ray tubes, to each of which a deflection voltage is applied, the two deflection voltages being in phase-quadrature, so that on one cathode-ray tube one alternate pair of pulses is displayed close to the centre of the screen, and on the other cathode-ray tube the other alternate pair of pulses is displayed close to the centre of the screen. Exploring pulses at 400 p.p.s. from the transmitter 11 are radiated from the common transmit-receive aerial system 15 which is rotated to -provide the conical scan by the synchronous motor 22 driven from the 100 c/s. generator 25. The generator 25 also synchronizes the 400 e/s. generator 24 which supplies the transmitter 11 with a 400 c/s. signal to control the transmission of pulses. Reflected echo signals amplified by the receiver 13 are selected by the " range gate " 32 which is controlled by a 400 c/s. signal from 24, and, passed to the indicators 27, 28. Each indicator comprises a cathode-ray tube and a phase-adjusting network: A 100 c/s. sinusoidal signal from the generator 25 is applied to the horizontal deflection plates of each cathode-ray tube, a 90 degree phase-shifter 41 being inserted into the lead to the indicator 27 so that the deflection voltages are in phase-quadrature. The echo signals from 32 are applied to the vertical deflecting plates of the cathode-ray tubes and the phase-adjusting networks so adjusted that the signals received when the aerial lobe is deflected to the left and to the right in azimuth are displayed side-by-side at the centre of the screen of the indicator 27, as shown in Fig. 7B, the pulses corresponding to the other two positions of the lobe being deflected off the screen. When the lobe is in either the " up " or " down " position the signals received are displayed at the centre of the screen of indicator 28. The relative amplitudes of the pulses indicates the direction and the degree of misalignment between the aerial scanning axis and the direction of the reflecting object.

Title: Improvements in or relating to the propulsion of marine craft
Inventor: PRIVETT JOHN RICHARD
IPC: B63H23/04
Filed: 1958-01-14
Abstract: 854,786. Drive for marine variable pitch propellors. TRANSPORT EQUIPMENT (THORNYCROFT) Ltd. Oct. 28, 1958 [Jan. 14, 1958], No. 1306/58. Class 114. In a marine propulsion unit a gas turbine (not shown), disposed with its shaft vertical, drives a variable and reversing pitch propeller E via a centrifugal clutch 4, or drive shaft 6, right angle gearing 8 and 10 and a propellor shaft 9. The clutch 4 is adapted to engage when the turbine rotates above its self sustaining speed. A pressure pump, driven by the gear train 14, 15 and 16, delivers oil for the hydraulic operation of the control valve 21 via a pipe (not shown), communicating with an inlet passage 18a and an axial passage 21a. The control valve 21 is operated by load via control rods (not shown), levers 19 and a bridle 20. Oil admitted under pressure to the appropriate side of the ram 25, operating in a cylinder 26 carried by the propellor shaft 9, via the ports 23 and 24 effects an axial movement of the shaft 27 and a simultaneous angular displacement of the propellor blades 12 via the member 28, thrust block 29, pivot pin 30a and radial arm 30. If the pitch setting is altered by an abnormal load, by forcing &c., the propellors will return to the original setting automatically. Lubrication of the unit is effected by a bleed from the pressure pump to the gears 14, 15 and 16. A thrower 17, throws the oil clear of the clutch 4 on to the walls of the casing C. The oil drains downwards to lubricate the bearings of the drive shaft 6 and the bevel gears 8 and 10 and collects in the casing 7 to lubricate the mechanism contained therein, any surplus oil is withdrawn by a scavenge pump arranged in tandem with the pressure pump. A bleed from the hydraulic circuit pressurises the boss 13 to prevent ingress of water at the blades 12. The unit may be housed in a sound insulated and waterproof structure adjacent to the transom of the boat and project downwardly through a suitably sealed aperture in the bottom of the boat. It may be mounted outboard of a boat. It may work in association with a rudder or may be angularly moveable about a vertical axis under manual or power control. Twin units may be used to facilitate steering and manoeuvring. The axis of the drive shaft may be offset with respect to the axis of the turbine. In event of failure of the hydraulic system the pitch adjusting mechanism may be operated pneumatically. Specification 854,788 is referred to.

Abstract: 1,015,882. Separating particles from gases. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 10, 1964 [Jan. 11, 1963], No. 1338/63. Heading B1T. An apparatus for separating particles from a gaseous fluid comprises an orifice and an adjacent particle collector, so arranged that a portion of a fluid passing through the orifice enters the collector. The apparatus is intended for atmospheric sampling of particle sizes. Air enters through an orifice 5 in a plate 2, and a portion of it (e.g. 1%) enters the collector 3 and leaves via a filter paper 9, rejoining the air which by-passed the collector, and thence flowing with it through a duct 11. The size of particle collected is influenced by the diameter ratio of the orifice and collector inlet, and their spacing. Thus, a series of devices as shown may be coupled together, each orifice plate being placed immediately downstream of the point where the flows of the previous device are united, thereby obtaining size graded samples, Fig. 3 (not shown). The orifice and inlet may be narrow slots, or a series of annular openings to a plurality of collectors may be arranged downstream of a circular orifice.

Abstract: 234,532. Sachsenwerk Licht - und Kraft Akt.-Ges., Sarfert, W., and Hartwagner,. L. Jan. 23, 1924. Alternating-current commutator and induction machines. - An asynchronous cascade set comprises two mechanically-coupled machines, the secondary winding b of the first machine being connected with the primary winding c of the second machine; the primary member of the second machine is provided also with a commutator compensating winding e which is connected to the secondary winding d of the same machine through a single set of brushes fixed relatively to each other. If the voltage in the winding b corresponds to the required compensation voltage, the windings c, e on the rotor of the second machine may be combined, or if the voltage in the winding b is too high, the connections shown in Fig. 3 may be employed. To minimize sparking at the brushes during starting, the starting resistance may be inserted in the primary circuit of the second motor. Three main speeds may be obtained by running the two machines in cascade and by running each one separately. Fig. 5 shows an arrangement whereby the machines can be run separately or in cascade. The rotor of the first machine carries the primary winding b and also a commutator compensating winding. Further speed regulation may be effected by the use of secondary resistances.
