Title: Method of and apparatus for filling a tube or hose with a particulate solid

Abstract: 1,271,627. Filling tubes with particulate solids. FYENS SAEKKEKOMPAGNI A.S. 3 Dec., 1970 [3 Dec., 1969], No. 57421/70. Heading B8C. A tube or hose is filled with a particulate solid, e.g. sand, by causing a liquid carrier medium, e.g. water, to pass through the tubular hose by means of a pressure source, introducing the particulate solid into the carrier medium downstream of the source of pressure, and regulating the rate of flow of the carrier medium so that as the area available for the flow of the carrier medium and the tube or hose is reduced due to the sedimentation of the particulate solid and the tube or hose, then the rate of flow is maintained within the range in which sedimen- . tation takes place. As shown, a tube or hose 1 which may be made of a flexible porous material or of a material impervious to water, is placed on a support, e.g. the sea bed, and water is pumped through a pipe 6 into the tube or hose by a pump P until a predetermined pressure is established by regulation of a discharge opening 3. Sand is then fed from a tank 8 into the pipe 6 and as sedimentation takes place the water flow through the tube or hose is regulated by a valve in a pipe 6<SP>1</SP>. In another arrangement, Fig. 2 (not shown), the pump P is replaced by a pressurized water tank (13) and the pipe 6 is additionally connected. to the tank 8 by a. valvecontrolled by-pass pipe (9). In a further arrangement, Fig. 3 (not shown), the tank 8.is connected to the tube or hose through an additional connection (5), the tank 8 also being connected to the water supply whereby the sand is carried by water directly, into the tube or hose. The pipes 6, 6<SP>1</SP> and 9 are as in the Fig. 2 arrangement. The filled tube or hose may be used for coast protection purposes.

Abstract: 1330970 Radar SIEMENS-ALBIS AG 23 Dec 1971 [22 Jan 1971] 60030/71 Heading H4D A distance measuring system includes stations mounted at each end of a distance, each transmitting a different measuring signal modulated on to different carrier waves and each station mixes transmitted and received signals to provide a difference signal which is reported back from one (subsidiary) station to the other (main) station by means of an in phase pulse train modulated on to the local carrier signal wherein the pulse train comprises pulses each of which is bipolar and the frequency spectrum of which contains substantially no component at the pulse repetition rate (i.e. the difference signal frequency). In the subsidiary station the difference signal is first squared up (Fig. 2a) and then added to an inverted delayed version of itself (Fig. 2b) to produce pulses indicating the zero crossings (Fig. 2c). These pulses generate a single cycle bipolar pulse (Fig. 2d) by means of a R.C. tuned circuit whose time constant equals the pulse width #. These bipolar pulses are used to frequency modulate the carrier signal which on reception by the main station undergoes filtering to derive the reference difference signal and frequency discrimination to detect the reported back difference signal. The phases of the two difference signals are compared to determine the distance between the two stations. Since the bipolar pulse train contains virtually no component at the difference frequency (Fig. 2h), cross-talk is greatly reduced.

Abstract: 1,245,789. Digital code converters. OLYMPIA WERKE A.G. 18 Dec., 1968 [28 Dec., 1967], No. 60058/68. Heading G4H. A diode matrix 1 is used alternatively for decoding a combinational signal on the column wires or for encoding a signal on one of the row wires. When the matrix is used as a decoder, mark and space signals are applied to the inputs EV 1 -EV 4  and #EV 1 -#EV 4  connected via diodes to corresponding column wires. The switch 9 applies 22 volts to common lead 8. One of the row wires 11 1 -11 16  receives a signal from the diode connections and this is passed to an output terminal via one of the gates 17 1 - 17 16  enabled by switch 18 placed in the appropriate position. Alternatively, if one of the switches TS 1 -TS 16  is closed to mark one of the row wires, an output is available from the column wires via gates 4 enabled by switch 18 in the other position. The mark column wires are connected to the output-terminals by gates 4 enabled by switch 18 in the other position. During this operation the switch 9 places earth potential on the line 7 common to the column wires. Switch 9 may be controlled to switch automatically into the required position by OR gates 12 and 13. When a combinational signal is applied to inputs EV 1 -#EV 4  OR gate 12 causes switch 9 to energize line 8. An input for one of the row wires is detected by OR gate 13 to switch the switch 9 to the other position, earthing line 7. Manual means may be provided to actuate the switch 9. The control inputs to switch 9 are connected to an OR gate 15 the output of which provides a timing signal.

[Class 40 (iv)] In apparatus for recording sound, the total frequency range is divided into upper and lower bands, for instance, up to 3000 c.p.s. and above 3000 c.p.s. The upper band is then transposed to a lower range by modulating it with a higher frequency, e.g. 6000 c.p.s., and suppressing the upper side-band. The resultant and the original lower band are then recorded on separate tracks. During reproduction, the higher frequency band is restored to its original range, by again modulating with the highfrequency and suppressing the upper side-band, and the two outputs are combined in a hybrid coil. The two tracks may be made as parallel records on the same disc, on separate discs or on opposite sides of the same disc.

Abstract: 1,208,830. Modified checkers game. R. V. FYANES. 27 Dec., 1968, No. 61517/68. Heading A6H. Apparatus for playing a modified game of checkers (draughts) comprising two distinguishable sets each of sixty-four markers 40, Fig. 5 one hundred and twenty-eight transparent markers 40, two distinguishable sets each of twelve conventional checkers 30, and a moulded or laminated folding square checker board 10. The board bears the conventional pattern of eight rows of eight squares comprising, Fig. 1, thirtytwo normal playing squares 12 and unoccupied in normal checkers, thirty-two non-playing squares 14 which are recessed to receive correspondingly shaped factor cards 20, Fig. 3, of which there are two "decks" each "deck" having sixteen factor cards. The factor cards between them bear, as factors, the fifty-two denominations of a conventional pack of playing cards, each factor card being quartered and bearing only one factor in any one quarter. Each "deck" comprises four factor cards each bearing four factors, eleven factor cards each bearing three factors and each having one blank quarter, and one factor card bearing three factors- and having, in its remaining quarter, a special marking to serve as a "penalty free exit".  In playing the game the two players each take and shuffle one "deck" of factor cards and place one card face up in each of the recessed squares 14 that lie in their own half 10a or 10b of the board 10, and place checkers 30 as for a conventional game of checkers. The players play such a game on the squares 12, but when a player has checkers in his opponents' half he may move them, forward or sideways, onto an adjacent factor card, and claim one of the factors printed thereon, the particular factor being indicated by one of his set of markers 40, the corresponding factor in his own half being indicated by a transparent marker 40. Thus by playing a game of checkers each player tries to win a game of gin rummy, for example, by building up an appropriate "hand" of cards obtained from the factor cards.
