Patent GB-259589-A (GB)
Title: Repeaters for multiplex signalling systems
IPC: H04L5/06
Filed: 1926-10-07
Abstract: 259,589. British Thomson-Houston Co., Ltd., (Assignees of Sattelberg, 0.). Oct. 7, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Diplex, duplex, and multiplex telegraphs; systems employing non-contact making relays. - The twoway repeater systems already used in telephony are adapted for harmonic telegraphy by the use of filter circuits. In harmonic telegraphy the duplex use of the line tends to produce interference between the signals, so that ordinarily a separate channel must be employed for each direction of working. According to the invention, however, the wave filters (which in telephony pass the voice-frequency band in both directions) are so designed as to pass two different ranges of frequency in the two directions. This result may be achieved by suitable dimensioning of the filters in an ordinary telephone two-way repeating bridge; or the system may be simplified as shown in Fig. 2, where the three frequencies w1, w2, w3, lying in one band are used for signals passing from left to right through a filter 9 and an amplifier 7, while three other frequencies w4, w5, w6, lying in a different band, are used for signals passing from right to left through a filter 10 and an amplifier 8; the action of the filters prevents interference between the two bands. By using two pairs of filters it is practicable to amplify in both channels with a single amplifier, and this modification can be extended to enable a single amplifier to be used both for receiving and for transmitting at a terminal station. Thus the incoming frequencies w1, w2, w3 pass from the line 1, Fig. 4, through the band filter 14, amplifier 13, and filters 21, 22, 23, which separate the individual frequencies w1, w2, w3, to the appropriate receivers, while the out-going frequencies w4, w5, w6 pass from the appropriate tranmitters through frequency filters 18, 19, 20, the amplifier 13, and a band filter 16 to the line 1. The highest frequency w3 of one direction may be separated from the lowest frequency w4 of the other direction by an interval wider than the intervals between frequencies within either group, in order to ensure freedom from interference. Where a large number of frequencies are superimposed the repeater system, Fig. 2, may comprise additional channels in shunt with the channels A, B, each being devoted to a group of frequencies whereof the highest lies below the octave of the lowest, so that interference from harmonics may be prevented.

Title: Device for loading and unloading vehicles carrying loose material, more especially dust carts
IPC: B65F3/22
Filed: 1949-09-28
Abstract: 682,682. Loading and unloading sealed vehicles; shoots & hoppers. KELLER & KNAPPICH GES. Sept. 28, 1949. [Oct. 6, 1948; June 29, 1949] Nos. 24959/49 and 24960/49. Classes 78 (i) and 78 (iv). Material is loaded into a rotating drumshaped body on a vehicle by a blade wheel which comprises a cylindrical member having radial inwardly-projecting spaced blades and is mounted adjacent the open end of the body for rotation with it : a stationary shoot is disposed within the blade wheel in a downwardly and inwardly inclined position so that material fed to the blades at the bottom of the blade wheel below the shoot is carried round by the wheel for discharge onto the top of the shoot whence it falls into the body. In the cunstruction shownin Fig. 6 the shoot 18 is formed in a cover 17 winch may be rotated relatively to a ring 16 secured to a fixed casing 15 so that the shoot may be turned to the position shown in Fig. 7 in which material from the rotating body 1, carried from the bottom of the blade wheel 2 to the top, is discharged by the shoot 18. The cover 17 and shoot 18 is coupled to the blade wheel 2 to move it with through half a revolution between the charging and discharging positions when a cam 26 (Fig. 10) on the casing is depressed to allow a member 24 to be depressed by a spring about a pivot on the cover 17 into the path of projections 28 on the blade wheel. After the ring has completed its half revolution a further member 24 carried by it is raised by the cam 26 into engagement with a fixed stop 25. Strippers 34 carried by the drum 1 clear material from the edge 33 of the shoot 18 and replaceable resilient end flaps (not shown) on the inner edges of the blades 4 of the blade wheel make sealing contact with the cylindrical walls of the shoot 18. A receptacle 31 for receiving material which leaks between the cover 17 and the blade wheel 2 is provided with a bottom which may be opened for discharging it. In the construction of Fig. 4 the shoot is formed by a flap 9 which may be turned about a horizontal hinge 3 from the discharging position illustrated to an upper position in which it directs material falling from the top of the blade wheel 2 into the body 1. The gaps between the inner edges of the blades 4 are closed, except at the top and bottom of the blade wheel, by a fixed part-cylindrical member 5 as shown in Fig. 1. When loading the flap 8 shown in Fig. 4 is lowered about the hinge 3 to close the lower part of the body 1. The flap 8 may be capable of removal for unloading, instead of hinging to the position shown in Fig. 4. Since this construction has no fixed outer casing the part-cylindrical member 5 is supported by arms 12 and rollers 11 from the blade wheel and is held against rotation by connecting the lower pair of arms 12 to the chassis 13. The invention is preferably used in conjunction with a body formed with an internal screw which conveys the material toward its open end both during unloading and during loading.

Title: A method of artificially maturing alcoholic beverages
Inventor: FLESCH PETER
IPC: C12H1/00
Filed: 1966-08-08
Abstract: Alcoholic beverages are artificially matured by irradiating them with gamma rays from a cobalt-60 source, for alcoholic beverages rich in extract at 1 x 105 - 5 x 105 g /h for 10-30 minutes and for alcoholic beverages extract at the same dosage for 10-20 minutes. Prior to the irradiation the alcoholic beverages may be saturated with air, oxygen, nitrogen or carbon dioxide, or kept under a corresponding atmosphere, for influencing the radiolysis of the alcohol contained in them.  Alcoholic beverages rich in extract e.g. liqueurs contain, broadly, 150-400 g/l of sugar and have a specific gravity of 1.0-1.2. Alcoholic beverages poor in extract e.g. whisky and gin, contain up to 50 g/l of sugar and have a specific gravity of 0.92-0.97. Many alcoholic beverages are particularly mentioned. The irradiation may take place either in closed vessels or under continuous flow. Examples and other experiments are disclosed according to which "Privat" spirit was exposed to 2.8 x 105 g /h of gamma irradiation from a cobalt-60 source for 15, 30, 45 and 180 minutes, respectively, and "Blackberry Brandy" was exposed to 2.6 x 105 g /h of the irradiation for 10, 20, 30 and 60 minutes, respectively.  Corked bottles of the alcoholic beverage sealed in polyethylene bags were irradiated from a cobalt-60 source located at the bottom of a water filled pit 4.5 metres deep.  The temperature of the water was 21 DEG C.

Title: Inductive coupling and regulation of coupled electrical oscillatory circuits
IPC: H01F21/06
Filed: 1937-09-15
Abstract: 507,655. Transformers; coupling coils. MICHAELIS, E. Sept. 15, 1937, No. 25094. Void. Convention date, Sept. 15, 1936. [Class 38 (ii)] In inductively coupled oscillatory circuits the coupling is adjusted without effecting detuning by movement of a magnetic dust core in relation to the windings. The coils 2, 3, Fig. 1, of a back-coupled oscillator for example may be mounted on an insulating former 1 within which the whole of the core 4 or a part thereof is so moved in relation to the windings that any detuning arising from change in coupling is compensated by change in self inductance of the coil 2. In a modification in which a part only of the core is moved to effect a change in coupling, Fig. 3 (not shown), the remaining part is independently movable to serve as a " balancing pin." Fig. 4 shows the invention applied to a frequency filter of adjustable band width in which the coils are mounted on fixed cores 11, 12 and the movable part 14 is adjusted laterally. In an alternative arrangement the fixed cores are axially bored to receive independently and axially movable core parts. Fig. 6 shows another form in which movable core parts 14, 15 are mounted for rotation with respect to fixed parts 11, 12 carrying the windings.
