Abstract: 228,908. Soc. D'Entreprise MeuniÞre, and Chopin, M. Feb. 4, 1924, [Convention d'ate]. Addition to 170,002. Testing flour and meal.-Relates to the continuous distension of a layer of predetermined thickness by gaseous fluid until rupture occurs, as described in the parent Specification, and consists in measuring the work required to distend the specimen with the aid of a device recording the pressure of the fluid producing the extension. Air is admitted through the pipe A below the specimen B and a pipe D leads to a device C constructed so that a constant relationship exists between the uniform rotary movement of the recording drum and the flow of air. The area of the diagram recorded gives the work done in distending the specimen and a relation between this and the weight of the specimen can be obtained. The paste is kneaded in a mechanically driven machine running at constant speed and is placed in a mould wherein the paste is rolled to a cake of constant thickness. Cakes of specimen dimensions are then stamped out by tubular cutting members. In a modified form of apparatus shown in Fig. 4, the upper plate A pivots about a spindle o carried by the lower plate and serves to compress the specimens until the plate abuts against a thickness gauge B<1>. The hole in the plate A is closed by a cone piece D secured by a few threads, the piece D being removed during the test.

Abstract: 539,194. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1940, No. 3712. Convention date, Feb. 28, 1939. [Class 40 (iii)] A transducer for coupling an output device O to an input device I of different impedance comprises two lengths of transmission line in tandem, each of a quarter the wave length corresponding to a mid-frequency f0 of the band to be transmitted, and their characteristic impedances Z 0 , Z 1  being such that the impedance Zm at the junction point is equal to the geometric mean of the terminal impedances R 0 , R 1 . The curves R, X represent the resistance and reactance components of the impedance as seen from the input device I, and it is shown mathematically that when the condition just stated holds, the slope of the reactance curve X is zero at the critical frequency f0, so that the impedance is substantially constant over a band of which that is the mid-frequency. It follows that the characteristic impedances are related to the terminal impedances by the equations Zo<SP>4</SP>= Ro<SP>3</SP>R 1  and Z 1 4=RoR 1 <SP>3</SP>. The frequency band may be widened further by using four lengths of line, in which case the characteristic impedances form a geometrical progression. According to the Specification as published under Sect. 91, equivalent ladder networks may be substituted for the lengths of transmission line.

Abstract: 1,162,957. Product bagging machine. AMERICAN MACHINE & FOUNDRY CO. 19 Jan. 1968 [25 Jan., 1967], No. 3746/67. Heading B8C. The product bagging machine described in Specification 1,088,222 is modified in that the output conveyer 12 has a part directly under the bag handling, or scoop device. Thus when the bag B has been drawn around the product A, the latter being held against a stop, the bagged product can then be allowed to drop vertically on to the output conveyer. The height of the scoop above the output conveyer is equal to or larger than the maximum opening between the scoop jaws 10, 11. It is this height through which the bagged product falls. In order to compensate for the tendency of the product to fall in an inclined position, the output conveyer can be modified either by having an equivalently angled wedge under the scoop, Fig. 3 (not shown), or by having the conveyer belt tilted transversely corresponding to the inclination and gradually reverting to the horizontal position towards the discharge end, Fig. 5 (not shown). Plates 18, 19 on either side of the conveyer at the filled bag receiving position locate the bag and partially fold the mouth end, Fig. 6. An air jet 20 also assists the closing of the mouth. Reference has been directed by the Comptroller to Specification 1,088,233.
