Patent GB-213305-A (GB)
Abstract: 213,305. Odhner, V. J. Nov. 22, 1922. Multiplying and dividing apparatus.-A camdisc and pin-wheel machine is provided with inter-acting crank-handle and cam-disc locks so that when one lock is active the other is inactive, the cam-drive lock being positively forced into active position by the crank-handle without the use of springs. The pin-wheels 3 are carried by the hollow shaft 2 to which is fixed the crank 4. Pivoted at 5 to the crank 4 is the handle 6, 7 the free end 8 of which co-operates, in the zero position of the crank, with a notch 9 in the frame of the machine. In addition, a roller 10 on the part 7, or on the frame, co-operates with a guidering 11 on the frame, or on the part 7 respectively, so that the part 8 can become locked in the notch 9 only when the roller 10 is in a recess 12 in the guide 11, that is in zero position of the crank. The part 7 also carries two rollers 15 operating a sliding sleeve 14 which through a bell-crank rocks a shaft 20, Fig. 4, carrying a sector 19 meshing with teeth on a ring 24 having a notch 26. In the zero position of the crank this notch 26 coincides with a notch 27 in a stationary ring 25 but when the crank-handle is depressed and turned the sector 19 is turned to the dotted line position in Fig. 4 and there is forced upwards out of the notches 26, 27 a roller 29 on a member 30 so that this member 30 is forced upwards, against the action of a spring 30<1>, to lock in teeth on the cam discs 13. Thus when the crank handle is locked the cam-discs are unlocked, and vice versa. According to a modification shown in Figs. 5 to 7 the handle 6, 7 is adapted to move radially in the crank 4 and the roller 10 on the part 7 co-operates with the inside of a ring 11. When the handle is depressed to the position shown in Fig. 5 and turned, it depresses a roller 33 on a part 32, this roller moving on the inside of a ring 35 on the part 7. The part 32 is thus depressed against the action of a spring 34 to form the continuation of the inside of the ring 25 so that the roller 29 and the part 30 are depressed and the cam-discs 13 are locked. There is also illustrated schematically, the combination of the radially sliding handle 6, 7 of Figs. 5 to 7 with the sector 19 and notched rings 24, 25 of Figs. 3 and 4.

IPC: C01B17/02
Filed: 1928-07-24
Abstract: 314,697. Manchester Oxide Co., Ltd., and Clayton, R. H. July 24, 1928. Sulphur. - Crude or impure sulphur, more especially that obtained in the purification, of coal gas, is purified by treatment in the molten state with sulphur trioxide. The impurities are then eliminated by filtration or by extracting with a sulphur solvent. The sulphur trioxide may be bubbled in fine streams through the sulphur and may ba obtained by passing a mixture of sulphur dioxide and air or oxygen over a catalyst, or by circulating air through burning sulphuric acid which may be heated. Before the treatment, air or other oxidizing gas may be blown through the sulphur to oxidize easily oxidizable impurities or the sulphur may be maintained in a heated condition to char some of the organic matter. The sulphur dioxide formed in the process may again be oxidized to sulphur trioxide, the process being operated cyclically and the system being purged from time to time when: necessary to remove excess of nitrogen, Air example is given in the Specification.

[Class 18.] In a case or carton for cigarettes, cigars, matches, or like articles, the body of the case is provided on one or on opposite sides at its open end with strips hinged or otherwise foldable together and connected to a sliding band encircling the case, so that by sliding the band along the case to open it the strips next to the mouth of the case are moved to be outside the case and at a right or other angle thereto, and on a reverse movement of the band, the strips fold across and act as a lid for the case. To the sides 1, 1a of the case, at its mouth are connected strips 2, 2a, 2b, 2c which are hingedly connected together, the strip 2c being hinged also to a band 3 which is slidably mounted on the case. When the band 3 is moved down the case the strips move from the position shown in Fig. 1 where they enclose the ends of the articles in the case to the fully open position shown in Fig. 3. The band 3 preferably has frictional contact with the sides of the case so that it may be held in any position. The box may be made from a blank, for example as shown in Fig. 4. This comprises a rectangular portion, with crease lines such as A and extensions 4, to form the walls 1, 1a and the narrow walls. Above this is another portion 5b with a cut-away portion 5a and having crease lines such as B to form the strips 2, 2a, 2b, 2c. Above this is another portion 3 with an extension 3a and crease lines to enable it to fold to form the band 3. The bottom of the case is formed by an extension 5. If desired the folding strips may only be connected to one edge of the mouth of the case and may be of such a width as to extend completely across the mouth of the case in the closed position. In a modification only three strips are employed, and the walls of the case to which they are not connected are continued above the other walls and have projections at their top edges to limit the upward movement of the band 3, which may have projecting tongues to facilitate its manipulation. In another modification the walls carrying the strips are continued a short distance above the other walls. Modified blanks are shown to form these boxes. For deeper boxes extra strips may be added and the corners of the box may be slit or perforated. The band preferably fits frictionally around the case so that it will stay in any desired position.

Abstract: 1466726 Cathode-ray tube circuits SONY CORP 16 May 1974 [19 May 1973] 21890/74 Heading H4T In a horizontal pincushion distortion correction circuit employing a saturable reactor 8 (Fig. 3), a secondary winding 8b of which is in series with the horizontal deflection coils 7 and the primary winding 8a of which is driven by a transistor 15 having its base supplied with a vertical frequency parabolic wave derived from the junction between the vertical deflection coils 11 and a capacitor 12, an improvement in the correction at the central edge portions of the screen (e.g. in a television receiver) is effected by including a diode 19 shunted by a resistor 18 in the supply of the parabolic wave to the base electrode. Thus, in the vicinity of the centre of each frame scan, when the vertical parabolic wave has maximum amplitude, diode 19 conducts and short-circuits resistor 18 so that an increased amplitude of the parabolic wave is available at the base of transistor 15 and therefore an increased correction of the pincushion distortion results. The arrangement may be modified by the addition of a resistor 20 (Fig. 5) to adjust the magnitude of the central correction. In a further arrangement the voltage across a capacitor 22 (Fig. 6) which is charged via a diode 24 supplies an additional incremental correction voltage at the central edge regions.
