Abstract: 1,192,402. Selective printers &C. NIPPON ELECTRIC CO. Ltd. 22 May. 1967, No. 23675/67. Heading B6F. A teleprinter, in which the type character selection is effected in respose to a six-bit code signal applied to a character selection mechanism for angular and axial displacement of a type cylinder 31, Fig. 3, which is supported on a shaft 32 and has six rows of sixteen Japanese characters, is provided with an axial type character selection mechanism comprising a rockable bail 34a which is integral with a lever 4 and articulated through a lever 33 to the shaft 32, the vertical lift of the bail 34a, raised upwardly by the bias of a spring 36 when a drive arm 35 is rocked upwardly, being limited by selective interposition of one of abutting arms 39a ... 14a, Fig. 5, in the path of movement of the bail 34a. The abutting arms are integral with respective stop levers 39 . . . 14 which are mounted freely rotatably on a shaft 8 and provided with operating arms 10b . . . 14b, biased clockwise by springs 21 into notched recesses 18a, 19a, 20a of one or more slides 18,19, 20 which are mounted on slide bars 15, 16, 17 and spring biased downwardly. The selective application of signals to the slide bars 15, 16, 17 results in rocking of the associated operating arms 10b . . . 14b, which in turn rock their respective abutting arms 10a . . . 14a out of the path of movement of the bail 34a which comes to rest against the first unactuated abutting arm. To select the third row of type characters the slides 18, 19, 20 are operated in such a manner that the operating arms 10b and 11b are rocked clockwise so as to displace the abutting arms 10a and 11a out of the path of movement of the bail 34a. For printing of two special characters in the first row I on the type cylinder 1, the control arm 39b of the stop lever 39, which is spring biased in the opposite direction to that of the remaining stop levers 10. . . 14, is brought into engagement with a cross-pin (22, Fig. 4) loosely associated with the slides 19, 20, which require to be actuated simultaneously upwardly to rock the control arm 39b clockwise so that the abutting arm 39a is rocked clockwise into the path of the bail 34a. Actuation of one of the slides 19 or 20 results only in idle lifting of the respective end of the pin 22.

Abstract: 1,037,799. Cheese preserving. ARMOUR & CO. June 9, 1964 [June 10, 1963], No. 23935/64. Heading A2D. Cheeses are coated with preservative powder by impinging on all sides of the cheese air streams carrying dry sorbic acid powder under pressure, preferably 10-20 p.s.i., to embed particles of powder in the cheese. Excess powder not embedded in the cheese may be sieved to remove cheese particles and reused. Preferably the cheese is passed through a treating zone under negative pressure, for example on a mesh conveyer belt, which zone may contain sensing means such that the powder-bearing air streams are only applied when a cheese is present in the zone. It is stated that other bodies may be treated in like manner. Other preservative powders mentioned are salt of sorbic acid, metal salts of propionic acid, e.g. the sodium and potassium salts, and hydroxyl esters of benzoic acid.

Abstract: 296,091. Akt.-Ges. Brown, Boveri, et Cie. Aug. 25, 1927, [Convention date]. Eltctromagets. - An electromagnet has four arcuate pole-pieces d - - g arranged in pairs at opposite ends and sides of a cylindrical space enclosed by the coil a, so that the gaps between them can be bridged by two armatures i, k carried on a non-magnetic piece m on a spindle n arranged in the axis of the coil. The magnetic circuit is completed by iron end-pieces c and a casing b. An arrangement of two coaxial coils with the pieces m carrying the armatures at right-angles, so that the coils oppose each other can be used for measuring resistance or impedance by passing a current through one coil proportional to the current in the circuit to be measured and through the other proportional to the voltage. By shaping the pole-pieces appropriately the relation between the tongue and the angular displacement may be varied.
