Abstract: PCT No. PCT/FI96/00691 Sec. 371 Date Aug. 28, 1997 Sec. 102(e) Date Aug. 28, 1997 PCT Filed Dec. 20, 1996 PCT Pub. No. WO97/24848 PCT Pub. Date Jul. 10, 1997A method and receiver for identifying data transmission rate from a signal which has several transmission rate alternatives. The signal contains modulation symbols (201 to 206) which are formed as a vector and which are submatrices of a known, essentially orthogonal transform matrix selected on the basis of a combination of bits to be transmitted. A correlation is formed between a received modulation symbol (201 to 206) and the known modulation matrix, as a result of which correlation vectors (301 to 306) are produced, each correlation vector being composed of correlation values (311) which are used to detect the signal. By utilizing the correlation values (311) of one or more correlation vectors (301 to 306), an estimate (556) is formed for each data transmission rate representing the probability of the data transmission rate of the signal, and the estimates (556) are used to select the most probable data transmission rate to be used for detecting the signal.

Filed: 1997-04-21
Abstract: A method for quickly de-allocating physical channels (PDCH) assigned to packet switched calls in a GPRS supporting GSM digital cellular telephone network. An PDCH de-allocation RLC/MAC control message is broadcast to listening mobile stations from a base station subsystem (BSS) and contains a temporary flow identity (TFI) which is recognised by the listening mobile stations (MS). The mobile stations respond by terminating packet switched data transmissions on the identified PDCHs. The RLC/MAC message also identifies the number of PDCH time slots which can be used before de-allocation must occur.

Title: Anti aircraft rocket control system - predicting gyrometer type device replaced by low inertia device
IPC: F41G3/08
Filed: 1955-01-18
Granted: 1974-10-31
Abstract: An anti aircraft system using e.g. rockets, includes the use of a viewfinder for obtaining correction signals, and including the use of the angular speed of the line of sight, equal to the sum of angular speed of the firer, and the variation of the angle of sight against time, the variations of one of these against a given value from the angular speed of the line of sight, being constantly equal to and in the opposite direction to the other. The oscillations of the platform of the firer do not affect the bove correction value. The conventional predicting gyrometer is replaced by a low inertia device, and the gyrometer suspension system is cancelled. The low inertia device continuously measures the angle of sight and its variation.

Title: Improvements in methods of producing coloured photographic records
IPC: G03C7/26
Filed: 1940-01-19
Abstract: 539,781. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Jan. 19, 1910, No. 1183. [Class 98 (ii)] A dye image is produced in a photographic material comprising at least one silver halide emulsion containing a leuco-derivative of a dye or other dye-forming substance by a process in which, after production of a latent or silver image in the layer, the image is subjected to physical development or intensification, the dye image which simultaneously oxidizes the leuco-derivative or other dyeforming substance imagewise to dye, is removed by solution in a bath or baths not dissolving unchanged leuco-derivative or other dye-forming substance, and the latter is oxidized to dye by means of a bath or baths which mordent the dye to the colloid halides of the layer. The leuco-derivative may be waterinsoluble and the dye water-soluble, the latter being then removed by washing. Physical development of a latent or reversed silver halide image, or physical intensification of a silver image, after development and fixing, may be effected. Physical intensification by means of a plain silver nitrate solution is preferred. Leuco-derivatives of yellow, blue-green and magenta dyes may be incorporated in material having three differentially colour sensitive silver halide emulsions and of the three-layer or the two-layer mixed grain type. Leucoderivatives of di- and tri-phenylmethanes and of rhodamines and fluoresceins may be used. Derivatives specified are the leuco-derivatives of Brilliant Green, Malachite Green, Magenta, Crystal Violet, Flavaniline, Rhodamine, and Fluorescein. Decolourable filter layers may be provided between the superposed emulsion layers. In an example, the exposed film is developed, washed, and the leuco-derivative oxidized to the dye by immersion in a 10 percent. silver nitrate solution. The dye is re moved by washing, and is then treated in a bath containing potassium dichromate and hydrochloric acid, followed by an acid hypo fixing bath. The di-chromate bath oxidizes the silver to silver chloride and also oxidizes the leuco dye and mordants the resulting dye to the gelatin. In a modification, the silver may be first removed by treatment with a potassium ferricyanide and potassium bromide bath, followed by fixing, the leuco dye oxidized and mordanted with a potassium di-chromate-sulphuric acid bath, and the film cleared in a 30 per cent. hypo bath. Specifications 503,752, 521,746 and 521,888 are referred to.

Title: Improved means for indicating route and speed of motor vehicles
IPC: B60Q1/54
Filed: 1919-01-18
Abstract: 141,788. Cave, F. H., Pigott, G. G. C., Stewart, C. J., and Symondson, S. L. Jan. 18, 1919. Moving-map and like indicators for vehicles.- A route indicator of moving-web type for use on a vehicle is combined with a speed indicator and is operated through gearing from the same drive to ensure synchronization. The route indicator and speed indicator may be arranged in the same or separate casings. As shown, the route indicator is in a separate casing, the drive being obtained from the speed-indicator drive through spur or bevel gearing and a flexible shaft (not shown) secured to either end of a shaft 1. Rotation is communicated to a shaft 2 through an open belt and variable-speed cone pulleys 3, which allow adjustment of speed of the web to be made to suit different sizes of vehicle wheel &c. The movable cones are adjusted by a pivoted arm 28 and screw 41 with milled head. Alternatively, opposed conical drums with a crossed belt are used, in which case the screw controls a belt-shifter. A shaft 6 is rotated through pinion 4 and spur-wheel 5. From this shaft, wheels 8, 11 are driven in opposite directions through a wheel 7 and wheels 9, 10. Wheels 8, 11 are on a shaft 12 which can be driven in either direction through a clutch 25, moved at will to engage either wheel 8, 11 or to its central out-of-gear position by a screw and milled nut (not shown). The shaft 12 drives a feed-roller 16 through wheels 13, 14. The web bearing route indications passes between rollers 18, 19 over guide-rollers 16, 17 and is held against roller 16 by a spring-pressed idle roller 20 to ensure a friction grip. The slack of the web is taken up by crossed and open bands as shown, driven from a pulley on shaft 6 and passing round pulleys 22, 24 on the shafts of the rollers 18, 19. These bands tend to drive the rollers 18, 19 in opposite directions, but slip when the web is taut. The rollers 18, 19 are removable, each being held between a fixed centre and a spring-pressed cen. tre which can be retracted.

Title: Sound producing device
Inventor: WALSH LINCOLN
IPC: H04R7/20
Filed: 1969-01-09
Abstract: 1,245,541. Loud-speakers. L. WALSH. 9 Jan., 1969, No. 1402/69. Heading H4J A conical loud-speaker has substantially all the energy radiated from its interior surface absorbed. The cone is generated by rotation of a curved or straight line about an axis and may be of elliptical type. A11 of the slant lines connecting the smaller end and larger end of the cone are at least 50 degrees in relation to a plane perpendicular to the axis. Preferably the speed of sound in the diaphragm is greater than in air so that over a range of frequencies sound is radiated "coherently". A steep angled cone (Fig. 1) has a voice coil 3 in an air gap 5 and is held by flexible webs 6, 7 to a framework 2. A baffle 9 containing sound absorbent material 10, together with the web 7, encloses the lower end of the diaphragm 1. Material 8, which may be solid or foamed elastomer, e.g. polyurethane foam, also absorb internal energy. A disc 11 of sound absorbent material absorbs any energy reflected back towards the voice coil 3. In use the loud-speaker axis is vertical. By appropriate choice of the material and angle of the cone a cylindrical wave front is radiated horizontally (Fig. 6, not shown). Alternatively, the wave front may tilt upwardly or downwardly. Energy absorption at the diaphragm edge may be effected by elastomer ring sections 28, 29 (Fig. 4) enclosing fluid in which a ring 31 moves, or by magnetic damping (not shown). An alternative loud-speaker (Fig. 5) has an aluminium diaphragm 1 to which is bonded a paper layer 32 and a tapered layer 33 of foamed polyurethane. The cone angle is 80 degrees or more. Alternative diaphragm materials are paper, plastics and hard fibre. The diaphragm may be made in segments with the grain of the diaphragm material properly oriented, or it may be moulded, pressed or formed from flat sheet with one or more seams.

Title: Automatic gun
IPC: F41A15/08
Filed: 1940-01-25
Abstract: 572,536. Automatic guns. DOBREMYSL, J. Jan. 25, 1940, No. 1947. [Glass 92 (ii)] Relates to large-calibre automatic; guns of the short-recoil belt-fed type having a recoiling-carrier 6 for a transversely-sliding breech block 2 and means for returning the empty cartridge cases to the belt. According to the invention, means are provided for retaining the barrel in its recoiled rear position until the carrier reaches its rearmost position, the trigger means retaining the carrier being controlled by the barrel so that the carrier cannot be released until the barrel returns to its forward position. The barrel 1 and carrier 6 recoil together a short distance until the accelerating lever 25 on the barrel engages a fixed abutment 26 to impart a rearward kick to the carrier, a cam groove 5 in which engages a pin 4 on the breech block 2 serving to open the breech. The barrel is retained in rearmost position by a catch 21 engaging a notch 22, a lever 11 on the carrier engaging a surface 12 to operate a transporter 7 which by means of an extractor 8 moves the empty cartridge case back into the belt clip 39 previously occupied by the live cartridge. On reaching, its rearmost position, the carrier is retained by a catch 23, the barrel catch 21 is released by an incline x on the carrier and the extractor 8 engages a stop 59 to release the case. During the forward movement of the barrel by the return spring 16, a rod 29 engages a cam groove 33a. in the belt feed slide 33 to move a fresh cartridge into position for feeding into the breech chamber when the carrier catch 23 is released by the trigger 52. By means of a rod 50, Fig. 6, and a link 49 having a pin- and-slot engagement with the trigger, the release of the carrier catch 23 is prevented until the barrel has returned to forward position and effected the feed of the fresh cartridge. As the carrier returns, the lever 11 engages a pivoted stop 14 to thrust the transporter 7 forwards to load the fresh cartridge and the breech block is raised to close the breech, the carrier striking the firing pin 3 at the end of its forward movement. Specifications 566,973, 572,535. 572,546 and 572,547 are referred to.

Title: Storage devices
IPC: G11C11/06
Filed: 1961-01-13
Abstract: 947,723. Pulse storage circuits. STANDARD TELEPHONES & CABLES Ltd. Jan. 13, 1961 [Jan. 19, 1960], No. 1557/61. Heading H3B. To overcome the effects of contact bounce which spoils the waveform of metering pulses to be registered in a first matrix M1, the elements of which are read out cyclically and each of which has an input from the metering relay of a telephone subscriber, a bit read out of an element in the first matrix M1 is transferred to a main store H and is also registered in the corresponding element of a second matrix M2 which duplicates all the elements of M1, the presence of an output from this element in matrix M2 in the next interrogation cycle inhibiting the transfer of any output from the corresponding element in matrix M1 to the main store H. The matrices M1, M2 are ferrite core arrays which are read out and reset in synchronism by the same source A. If the metering pulses are mutilated by contact bounce as shown by waveform a of Fig. 3, and are interrogated by the narrow pulses shown by waveform b of Fig. 3, then it is possible when an interrogation coincides with a mutilation of a metering pulse that a core will have been switched sufficiently to provide an output to interrogation and will be switched again by the remainder of the metering pulse so as to give a second and spurious output at the next interrogation. It is arranged, however, that the first output from a core in matrix M1, over an amplifier and sneak suppressor L1, is transferred to the main store H and also sets the core corresponding to itself in the matrix M2. At the next interrogation of these particular cores the output from matrix M2 over amplifier and sneak suppressor L2 inhibits a gate V to prevent transfer of a spurious output from matrix M1 and in the event of such a spurious output prevents its re-registration in matrix M2. The inhibition circuitry is simplified if the first output from a core in matrix M1 is not only written in the corresponding core in matrix M2 but is also re-written in the matrix M1 so that the next interrogation will always produce signals in opposition from M1 and M2. The outputs of the matrices M1 and M2 are staticized by bi-stable circuits F1, F2, so that they may control the subsequent writing functions.
