Abstract: 1,257,899. Baling presses. LINDEMANN MASCHINENFABRIK G.m.b.H. 7 July, 1970 [30 July, 1969], No. 32954/70. Heading B5F. A baling press for fibrous materials comprises a closable feed channel 13, 14 for the material, a pressing box 1, air conveying for assisting feed from the channel into the box 1, a plunger 10 for compacting material in the box 1, an air chamber 4 surrounding the box and communicating with the interior thereof through apertures in the box wall, and an air suction pump 6 which draws air containing particles from the chamber 4 and passes it through a filter 9 having an at least partially closable outlet 15 leading into the feed channel 14 so that particles drawn from the chamber 4 can be recirculated into the feed channel and pressing box. As shown, a flap 17 pivoted at 16 is arranged to close or open the feed channel 14 simultaneously opening or closing the filter outlet 15. A small gap 19 is preferably left in the filter outlet to promote flow through the feed channel 14. When fibrous material fed to the channel 14 reaches a height sufficient to interrupt a photo-cell assembly 18, the pivoted flap is moved to the Fig. 2 position.

Abstract: 1,265,167. Mono - 2 - haloethyl esters of 2- haloethanephosphonic acid. G.A.F. CORP. 28 Feb., 1969 [5 March, 1968], No. 10760/69. Heading C2P. [Also in Division C1] The invention comprises compounds of the formula XCH 2 CH 2 P(O)(OH)(OCH 2 CH 2 X) (I) wherein X is Br or Cl. The 2-chloroethanephosphonic acid derivatives may be obtained by (a) reacting ClCH 2 CH 2 P(O) (OCH 2 CH 2 X) 2  (II) with PCl 5  to form and then hydrolysing the latter, or (b) by reacting (II) with HCl to yield X in each case being Cl or Br. Methods (a) and (b) are exemplified for compounds in which each X is chlorine, hydrolysis being effected in (a) by stirring with warm distilled water and the HCl treatment in (b) being effected with anhydrous HCl gas at 160 C., the product in (b) comprising a mixture of betachloroethane phosphonic acid and its mono-2-chloroethyl ester. The mono-2-bromoethyl ester of 2- bromoethane phosphonic acid may be obtained in an analogous manner from the bis-(2- bromoethyl)ester of 2-bromoethane phosphonic acid. The products (I) particularly the mono- 2-chloroethyl esters are useful as plant growth regulators.

A piston-like motion of liquid in the channels is induced by incident waves such as 42, 44 which would otherwise be reflected from plate 16 due to their angle of incidence being greater than the critical angle. Plate 46 may be formed of aluminium, copper, brass, steel, glass or plastics, with a channel diameter of the order of a wavelength (for ultrasonic frequencies in the range 1 to 20 MHz), and may be attached (e.g. by cement) to plate 16 or supported adjacent to it by brackets on a tank containing the liquid 20. Plate 16 is scanned by an electron beam and the resulting secondary emission signal is applied via electron multiplier 36 to a cathode ray display tube.

With this form the strip enters a heater section F comprising plates 17, 18 forming a tapering inlet 19 followed by a substantially cylindrical guideway. In section F the tube is subjected to a final sizing and shaping to circular cross-section 1f and the edges are sealed together in a smooth butt joint. Finally the tube is passed through a cooling section G which can be in the form of an annular aircooler (not shown). The tubing is preferably drawn through the above system and presented to a cutter (not shown) by a traction unit H comprising a pair of driven grooved belts 23. The rollers of the various sections may be driven from the belt drive or may be driven independently. In an alternative arrangement the edges of the strip may be pre-treated with a heat-activatable adhesive and the adhesive applying section omitted. Concentric tubing may be produced from two or more strips passed through a single apparatus or two or more units arranged in series. The invention can be used to form cigarette filter tubes from suitable paper and preferably two strips of different porosity may be used.

The apparatus which may consist of a number of vessels in series may be used for reacting phosphate rock with sulphuric acid (see parent specification) to form phosphoric acid and calcium sulphate. The reaction mass in each vessel consists of slurry containing phosphate rock particles which are dense and tend to settle rapidly and calcium sulphate particles which are less dense and tend to settle more slowly. In each vessel, the slurry passing upwardly through the hindered settling column to the respective overflow outlet is the liquid component of the slurry carries with it only the lighter and smaller calcium subjected to classification in such a way that sulphate (or predominantly so) particles whilst the larger and heavier phosphate rock particles settle countercurrent to the flow in the column, at a rate exceeding the flow rate. These latter particles are retained in the vessel until, by digestion and partial or total conversion to less dense calcium sulphate particles, they may escape through the overflow outlet.

Abstract: 1339974 Radar display ELECTRONIQUE MARCEL DASSAULT 18 March 1971 7226/71 Heading H4D  A radar range/azimuth display comprises a mosaic 14, e.g. 6 x 6 of luminous elements which, in a first or "watch" mode, display the whole surveillance area of the radar, and in a "precise location" mode displays on an enlarged scale, a selected part of the surveillance area. After quantizing and digitizing in coder 21, the video of one range sweep is stored in register 20. Register 20 comprises shift register having one stage for each range increment, e.g. 36 and stores coded range, azimuth and amplitude information, as well as binary information as to whether the amplitude of an echo in a range increment is above #(1) or below #(0) on threshold. Under the timing control of read and address circuit 22, first logic circuit 23, AND gate 25, a circuit 29 sequentially feeds a 0 or a 1 signal to the rows of elements depending on the amplitude binary information stored in register 20, the signals for range increments D1 to D6 being fed to the first (uppermost) row, those for increments D7 to D12 being fed to the second row, and so on. The azimuth sweep of the radar is divided into 36 sections G1 to G36 and logic circuits 24 causes circuit 30 to feed a 1 signal to the correct column of elements 15, signals for sections G1 to G6 being fed to the first (leftmost) column and so on. Only that element 15 which simultaneously receives a column (azimuth) and row (range) 1 signals brightens up, thereby indicating the presence of a threshold exceeding echo in a range/azimuth area six range elements by six azimuth elements wide. The elements 15 may be lamps or electroluminescent diodes are preferably in the form of an illuminated pushbutton and may indicate in one of several colours to give information as the kind of echo (e.g. in IFF radar). To change to the "precise location" mode the selected illuminated element is pushed (in the case of push-buttons) or otherwise selected-e.g. a light pencil-and a switch 36 closed. Code converters 39, 40 deliver signals to an address indicator circuit 35 indicating the range/azimuth six by six area selected. These signals are fed to one side of a comparator 32 (exclusive OR circuits), fed at its other side with the range increment and azimuth section timing signals. Equality signals, indicating that echoes from the area are being received, enable logic circuits 43 and 44 and AND circuit 45 such that the area is displayed on the mosaic 14.
