Title: Fdma fdma cdma hybrid radio access methods
Inventor: DENT PAUL W
IPC: H04W72/04
Filed: 1995-01-10
Granted: 1999-06-30
Abstract: A radio access method for facilitating communication between at least one first station and a plurality of second stations is disclosed. First, each signal intended for transmission is buffered at a first station. The signals are then divided into equal length segments. The signal segments intended for a particular one of the second stations is transmitted using a corresponding time slot in a regularly repeating time multiplex frame. The signal segments transmitted by the first station are received at at least one of the second stations and the signal segments are assembled from successive corresponding time slots to reconstruct said intended signal. A transmit frequency channel uniquely associated with the corresponding receive time slot is determined at the second station. Finally, a signal intended for transmission to the first station is buffered in the second station and compressed for transmission using the transmit frequency channel during substantially the entire time period that the second station is not receiving. <IMAGE>

Title: Improvements in or relating to photographic cameras
IPC: G03B7/00
Filed: 1956-01-02
Abstract: 802,634. Photographic cameras. DECKEL, H., and DECKEL, F. W. Jan. 2, 1956 [Jan. 5, 1955; Feb. 4, 1955], No. 37/56. Class 98(1) In a photographic camera, a unit detachable from the body carries a component of the lens system, a variable aperture diaphragm, a depth-of-focus indicator and a focusing member rotatably mounted on the unit, the focusing member bearing a focusing scale co-operating with a stationary mark on the unit and the depth-of-focus indicator having a pair of movable pointers co-operating with the focusing scale. As shown in Fig. 2, a bayonet ring 14 on the front 10 of the camera engages a ring 16 on the detachable unit. A focusing ring 24 threadably engages a flange 22 fixed to ring 16, and has a rim 26 entering a space 28 between two parts 32, 34 of the unit. A pin 38 on flange 22 engages a slot 36 in the part 32, so that when ring 24 is rotated the unit moves axially without rotation. The part 34 carries a shutter housing 42 of known type, which carries the lens components 64, 66 and also houses an iris diaphragm actuated by a ring 48. Immediately behind the shutter housing is a depth-offocus indicator of the kind described in Specification 785,857, actuated by a ring 90 engaging ring 48 by means of an upturned lug 92, and having a pair of pointers, one of which is shown at 72, cooperating with the focusing scale 74 on ring 24. The shutter speed setting ring 50, mounted on the front of the shutter housing 42, has a skirt 52 which has recesses 54 at its lower edge. One of these recesses is engaged by a catch 56 on a coupling ring 58. A projection 60 of the diaphragm setting ring 48 engages a retaining slot 62 in ring 58, and is made of resilient material so that the ring 58 may be pushed back to disengage it from the shutter speed setting ring 50, and rotated with respect to ring 50. In a modification, a ring rotatably mounted on the front of the camera threadably engages a ring which is free to move axially without rotation, and the unit carrying the shutter, lens diaphragm and depth-of-focus indicator is detachably secured to the second ring. A focusing ring rotatably mounted on the unit has a pin-and-slot connection with the first ring. Further, the detachable unit may have a part fixed to the camera and a displaceable part carrying the lens. The fixed part may carry the shutter mechanism and/or the depth-of-focus indicator, the remaining parts being carried by the movable part. Specifications 763,154, 769,081 and 770,819 also are referred to.

Title: Improvements in electrical regulation systems
IPC: G05B11/01
Filed: 1948-01-01
Abstract: 633,597. Modifying reactive characteristics of electric circuits. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAG. Jan. 1, 1948, No. 41. Convention date, Jan. 11, 1947. [Class 38 (vi)] In order to reduce the time constant of a circuit including an inductive winding 1 which is performing a regulating function, there is connected in series therewith a highly evacuated electronic valve 2 having the characteristic of a pentode to the screen grid 11 of which a constant voltage 7 is applied, and the regulation is effected by altering the valve characteristic as by changing the voltage applied to the control electrode 8. If the control grid voltage be such as to establish the characteristic curve A shown in Fig. 2, where the current in the winding 1 has the value il and the potential across the valve is el, a sudden increase of control grid voltage to establish the characteristic A1 will immediately reduce the potential across the valve to e2, and the surplus voltage e1-e2 and the power represented by the area C is available to raise the current through the winding 1 at a rapid rate. A beam tetrode with a like characteristic may be used similalry. The time constant can be further reduced by connecting a condenser 6 and reactor 5 in series across a low cathode resistance 3 and connecting the grid voltage source as shown. The winding 1 may be, for example, the control winding of a saturable reactor or the exciting winding of a generator and the invention is applicable to the restoration of a variable quantity to a normal value or to the intentional change of the normal value of a quantity. A specific application mentioned is the strong and strictly time-determined variation of welding current by a small control power. If the current controlled by the pentode refuses smoothing, as when its source is a single-phase two-way rectifier, the characteristic of the pentode is such as to absorb the voltage pulses substantially without current variation.

Abstract: 714.443. Discharge lamps. THORN ELECTRICAL INDUSTRIES, Ltd. Jan. 1, 1953 [Jan. 1. 1952]. No. 98/52. Class 39(1) An electric discharge lamp of the type comprising an elongated tubular envelope provided with at least two spaced electrodes and an external electrode for starting mounted thereon is characterized in that the external electrode is mounted by metallic members which are disposed externally of the envelope at or adjacent the ends thereof and which are cut to provide on each metallic member a strip which is bent away from the remainder of the member to provide a gap therebetween, a portion of the external electrode being engaged in each gap. In the construction shown in Figs. 1A, 2A and 5A two parallel cuts are made in the skirt of each end cap 10 and the strip 11 between the two cuts is lifted to provide a gap between the strip and the remainder of the cap. The external electrode 13, which may comprise a nickel base, is mounted by inserting its ends in the gaps and then pressing the strips 11 back towards their original positions to close the gaps. Preferably one end of the wire is attached to one of the two end caps and subsequently the other end of the wire is attached to the other end cap whilst the wire is under tension. The wire is fixed to the envelope along its length by a cement or glue. The cuts made in the end caps may be such that each strip is attached at only one end to the remainder of the cap, for example as shown in Figs. 3A and 4A wherein the strip 14 is triangular in shape and is formed by two intersecting cuts. The ends of the wire may be bent around their respective strips as shown in Fig. 5A or the strips may be bent around the wire as shown in Fig. 4A. In a construction of strip such as that shown in Fig. 4A the ends of the wire may be bent around the respective strips. In such construction it may not be necessary to press the strips back towards their original positions to close the gaps as is referred to above. Instead of cutting the end caps to form the strips or with a lamp that is not provided with metal end caps, for example as shown in Fig. 6, metal bands 15 may be provided round the lamp envelope at or adjacent to the ends thereof and the cuts may be made in the bands 15 to form the strips 11. Since no soldering of metal to metal is required, metals which would normally be very difficult to solder, for example aluminium, may be used for the end caps 10 or the metal bands 15 and/or the external electrode 13.

Abstract: 431,339. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. Jan. 3, 1934, No. 267. [Class 40 (iii)] In a skipping-line cathode-ray scanning system, the cathoderay beam is deflected at varying periodicity. Preferably the line periodicity is constant, while the slower component is of varying periodicity, but the higher frequency may be varied. In one example, twelve lines produced by wave forms A, Fig. 1, are divided into three intercalated sets by wave forms B, two of the wave forms B having a period equal to that of 3<2>/3 of wave forms A, while the third wave form B has a period equal to 4<2>/3 of that of the wave forms A. The scanning consists of an even number of lines in which certain sets have a prematurely concluded line, Fig. 2 (not shown). The system is adapted for co-operation with a transmitter in which skipping line scanning is produced by a rotating spiral disc 3, Fig. 3, and a mirror drum 8 as described in Specification 381,898. Synchronizing impulses for the generator 16 producing wave forms A are produced by interrupting the light falling on a cell 23 by a disc 20 having equally spaced apertures 21 equal in number to the mirrors on the drum. Synchronizing impulses for the generator 17 producing the wave forms B are produced by interrupting the light falling on a cell 26 by a disc 24 having unequally spaced apertures, Fig. 4 (not shown).

Title: Improvements in or relating to a method of making fluorine compounds of aluminium
IPC: C01F7/54
Filed: 1932-01-05
Abstract: <PICT:0383780/III/1> Aluminium fluoride or sodium-aluminium fluoride is obtained by passing a fluorine-containing gas, for example, fluorine, hydrogen fluoride or gaseous hydrofluosilicic acid, through an aluminium compound, or a mixture thereof with a sodium compound, at a temperature of from above 400 DEG  C. to about 700 DEG  C.  In a preferred method of producing aluminium fluoride, aluminium oxide, hydrate or other compound in granular or briquetted form is fed continuously or intermittently through valve 12 into shaft 10, for example, of mild steel.  Hydrogen fluoride, generated in still 14 from fluor spar and sulphuric acid, passes through manifold 15 and preheating pipes 16 to the bottom of the column of aluminous material, the top of which is maintained well above the manifold. Steam escapes through pipe 17 to which may be attached a suction fan. The converted material is discharged through valve 13. Pyrometers 19 are inserted in the shaft 10.  Heat which may be required initially or during the reaction may be obtained by burner 18.  Alternatively, the gas may be preheated.  A preferred starting material is aluminium trihydrate previously calcined between 575 DEG  and 1575 DEG  F. Thereby, it is unnecessary initially to supply heat.  It suffices to employ only a bottom layer of this material.  The reaction temperature may be controlled by precooling the gas, or by directing an air blast or water spray on the chamber, or by means of a water jacket around, or pipes within the chamber.  Another method consists in mixing the raw material with aluminium fluoride.  When powdered raw material is used, it may be supplied to one end of a rotating drum and the fluorine-containing gas at the other, the finished product being discharged intermittently by valve mechanism. Artificial cryolite may be obtained thus by feeding hydrogen fluoride and a mixture of aluminium oxide or hydrate and soda ash into a tumbling barrel.  The Specification as open to inspection under Sect. 91 comprises also the production of fluorides of other metals, such as zinc, barium, and magnesium fluorides, and sodium fluoride and bifluoride.  Carbonates are specified as raw materials, and no limitation is imposed as to the lower temperature limit.  This subject-matter does not appear in the Specification as accepted.
