Title: Buttonhole cutting and stitching machine
IPC: D05B37/02
Filed: 1919-04-05
Abstract: 146,588. Fairweather, W., (Singer Manufacturing Co.). April 5, 1919. Button-hole and eyelet-hole sewing-machines; button-holes, cutting. - The work-clamp is closed upon the work in the stitching position and is then moved rearwardly to meet the cutters which are simultaneously moved forward from their inoperative position. The workclamp is uncoupled from the feedwheel for this movement, which is imparted to it by a temporary connexion with the cutter-operating shaft. Fig. 3 shows the parts in the position occupied at the beginning of a cycle. During the stitching operation, the workclamp is moved longitudinally by a pin 34 which is adjustably fixed on. a carrier lever 29. The lower end of the pin enters a cam-slot in the feedwheel, and the upper end is contained between a part 35<1> of the work-clamp plate and a part 36<x> of a lever pivoted upon the work-clamp plate at 38 and normally in the position shown. For the cutting operation, the cutter shaft 50 is given a single revolution. A cam-groove 58 rotates a lever 56, and after moving a plate 47 through the length of the slot 45, the lever 56 depresses the lever 36 and removes the part 36<x> from in front of the pin 34. A cam groove on the further side of the disk 49 then operates through the link 47 and the lever 36 to draw the workclamp rearwardly to the intermediate cutting position. Simultaneously, the cutter levers 67, tiS are moved forward to the same position, and the button-hole or eyelet-hole is cut. Afterwards the parts are returned to their initial positions, and by means of the lever 56 the plate 47 and the lever 36 are raised. This replaces the part 36<x> in front of the pin 34 and effectively recouples the work-clamp to the feed-wheel. The lower arm of the slot 45 is sufficiently long to permit the full movement of the lever 36 with the work clamp during stitching.

Title: Cathode ray tubes and display systems for colour television receivers
IPC: H04N9/26
Filed: 1952-04-04
Abstract: 720,315. Colour-television tubes. EDISON SWAN ELECTRIC CO., Ltd. April 4, 1952 [April 7, 1951]. No. 8723/52. Class 39 (1). In a colour television receiver the beam passes through a multiapertured plate 4, Figs. 1, 2, carrying the plural colour phosphor areas on the side remote from the gun, and strikes a transparent secondary emissive electrode 18, the secondaries returning to bombard the phosphor areas. In the form shown the transparent end wall 2, is planar or spherical and has a transparent conductive coating 17 of tin chloride on which is formed a transparent secondary emissive layer 18 having a secondary emissive ratio of 5 or 10:1 which may be MgO, MgF 2 , Al 2 O 3  or CaF 2'  coatings 17, 18 being formed by evaporation. Perforated plate 3 which may also be planar or spherical is coated with different phosphors in dot clusters 4, each cluster being three dots of different colour response preferably red, blue and green, surrounding a respective aperture, Fig. 3 (not shown). The centre of curvature of wall 2 and screen 3 is at the centre of deflection. Screen 3 is connected to second anode 10 by internal connection 14, and conductive coating 17 has a smaller positive potential chosen to give maximum secondary emission. Coil 11 generates a rotating field to vary the beam direction by means of colour synchronizing signal components so that the desired colour response is obtained at the desired time. The retarding field between 3 and 18 bends the electron trajectories (as in general they enter 3 at an angle inclined to the normal) and tends to amplify the initial deflection. The secondary emissive coating may be on a separate transparent plate spaced from the tube end wall. The phosphor dots may have only two colours of response. The input signals may or may not have a carrier; in the former case they can be transmitted over lines. Specification 713,875 is referred to.

Title: Improvements in multiple speed mechanism for slicing machines
IPC: B26D1/143
Filed: 1926-04-06
Abstract: 256,892. Fitzpatrick, H. D., (United States Slicing Machine Co.). April 6, 1926. Controlling variable-speed gearing. - In a slicing-machine, the knife is driven through change-speed gearing 56, 60 - - 64, Fig. 2, and a. clutch 38, 42 driving the shaft 30. The clutch and change gear controls are interlocked. The clutch 38. 42 is engaged and disengaged by a rod 46 slidable in the shaft 30 and secured to a cap 47 revoluble by a handle 55, the cap having pins which engage the helical groove in a stationary stud 53 whereby the rod 46 is moved axially to operate the clutch. The change-speed pinions 62, 63, 64 are carried on a sleeve 68 which is moved axially along the shaft 65 by a fork-ended rod 70 having an operating knob 71, whereby the pinions are engaged with the pinions 56, 60 or 61 respectively. Interlocking gear, to prevent gear-changing when the clutch is engaged or to prevent the clutch from being engaged when the gears are in an intermediate position, comprises a spring-pressed detent 72 which engages one of a number of grooves 73 in the rod 70, each groove corresponding to a, gearengaged position. An extension 82 on the detent 72 engages the cap 47 and prevents the detent from being released from its groove 73 when the clutch is engaged. When the cap 47 is revolved to disengage the clutch, the extension 83 registers with an opening in the cap 47 which allows the detent to be raised when the rod 70 is moved. The detent is kept raised when the gears are not properly engaged, thereby preventing re-engagement of the clutch. Modified gear and clutch interlocked control mechanism is shown in Fig. 5. The clutch is operated by a lever 113 pivoted at 114 and operated by a cam 120 on a shaft 121 rotated by a handwheel 124. The gears are changed by a sliding rod 102 which has rack teeth engaged by a pinion on a shaft 106 which carries a disc 109 and a handwheel 108. The disc 109 is held, when the clutch is engaged, against rotation by a spring-pressed detent 110 which has an extension 117 which registers, when the clutch is engaged, with a stop 116 on the lever 113. To enable the gears to be changed the stop 116 must be displaced by disengaging the clutch, and as the extension 117 will lie in the path of the stop 116 unless the gears are properly changed, the clutch cannot in that case be re-engaged,
