IPC: B65G53/30
Filed: 1918-12-17
Abstract: 136,624. Murdoch, C. M. Dec. 17, 1918. Tip-boxes; loading vessels with solids by transmission in a current of liquid.-Coasting vessels, barges, dredgers, &c. are loaded with solids which can be transmitted in a current of liquid by a centrifugal pump, which delivers through a pipe I to a separating-tank A pivoted on the deck of the vessel. The tank A is open and contains a screen which is spaced apart from the sides and bottom. The solid is retained in the screen, and the liquid passes away through the pipes' F, G. When the screen is full, the tank is tipped, and the solid passes into the hold.

IPC: B64D17/72
Filed: 1927-08-10
Abstract: 275,994. Fabry, C. Aug. 10, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Parachutes; aerostats.-A parachute is opened and maintained open by compressed air or gas discharged from a container suspended in the parachute, when released by the user or by automatic means. A cylindrical container 2, Figs. 1 and 2, is packed with the parachute envelope and is attached to the central opening by cords. The container is surrounded by a perforated casing 5 to distribute the air or gas upwardly and laterally when a series of cocks on automatically-regulated valves 6 are opened by a pull on a chain 12. The valves 6 have a diaphragm 7, Fig. 4, acted upon by the pressure in the container to tend to close a valve 9 against the action of a spring 8. A modification is described in which an inflatable tube at the periphery of the parachute encloses two small compressed-air containers having valves at each end so that the tube is distended when the valves are opened. Fig. 5 shows a modification in which the parachute is formed as a small balloon, the upper and lower fabric enclosing a container 2<1> of compressed hydrogen which issues through a perforated partition 4<1> when a valve 6<1> is opened.

Title: Data transmission system
IPC: H04L25/49
Filed: 1971-04-19
Abstract: 1346607 Digital transmission; multi-level coding PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [12 Feb 1970] 21403/71 Heading H4P Binary signals from a source are divided into groups of k bits, where k = at least 2, which are coded into 2n + 1 (equal to at least 5) amplitude levels for transmission, the series having spectral zeros at determined positions. Binary signals are applied to a coder 4 having a multi-level output of at least five levels applied through a low pass filter to an amplitude or frequency modulator 6, also fed by oscillator 7. Spectral and zero points are arranged to occur at prescribed positions in the frequency spectrum which may be utilized for co-transmitting pilot signals. The output is passed through a band pass filter 8 and amplifier 9 to line 10. In the receiver, the order of components 5-9 is reversed. The output from low pass filter 15 is full wave rectified at 28 and multi-level decoded at 30, 31 providing a binary series corresponding to the input to 17. The multi-level coder comprises a pulse group analyzer 18 analyzing successive groups of k binary pulses and supplies to n parallel lines a binary series characteristic of each group. At each instance not more than one of the m output lines has a value of "1" and the number of pulses in the series is smaller for all lines than the number of pulses k in the analyzed group. All lines incorporate a mutually equal pseudoternary code converter 19-21 and m-1 lines has an amplitude multiplying device 22, 23 having factors of x2, x3 respectively the outputs of which are combined in a linear adder 24 giving out a multi level pulse series having 2m + 1 levels. In the embodiment m = 3 output lines and k = 2 pulses per group hence the correspondence is as follows:- i.e. a 1 pulse on any line identifies the first three groups and 0's on all lines the fourth group from which the converter 19 derives levels - 1, 0, +1, multiplier 22 derives -2, 0, +2 and multiplier 23 the levels - 3, 0, + 3 all of which are applied to adder 24 and passed to the transmission line via components 5-9 previously described. By coding in the above manner (Gray code) it is assumed that only one of the pulses in each group k will be erroneous if the interferences are not too large. For introducing spectral zero points a digital filter is used. Output filter 5 may also be replaced by a digital filter (65), Fig. 9 (not shown), comprising a cascade of shift register elements (68-71) advanced by multiplied clock pulses from (74).
