Abstract: 1,016,934. Photographic type-composing apparatus. N. MORISAWA. Aug. 2, 1963, No. 30808/63. Heading B6W. In photographic type-composing apparatus having a " negative " character plate manually movable for selection for step-by-step reproduction of single characters on light-sensitive paper, the character plate 21, Fig. 5 (not shown), is provided with a " negative " character board 21, an indicator board 32, a rack 24 and adjusting pieces 25 which are proportionate in height to the breadths of the characters on the plate. The character plate 21 is mounted for manual positioning in a longitudinal and transverse direction beneath a lens tube 42, Fig. 1, and light from a source 39 is directed with reflectors 40, 41 through the plate 21 into the tube 42. A magazine of film or light-sensitive paper 77 is mounted for line-wise movement above the tube 42. When a character is selected, a button 37, Fig. 1, is pressed to excite an electromagnet 35, and a pawl 30 meshes with the rack 24 to hold fast the character plate 21. When a button 49 is pressed, an electromagnet 44 is excited to operate a shutter 48, Fig. 3 (not shown), and a relay is excited to operate an electromagnetic clutch to engage the drive of a cam-shaft 50, Fig. 1, for one revolution. A cam 51 provides through a follower 56 and various linkages 55 &c. the movement for a cover-plate 68 around the periphery of a ratchet-wheel 66, and the amount of movement is governed by a rod 58 coming into contact with the adjusting piece 25 associated with the selected character. The ratchet wheel 66 operates through gears, Fig. 6 (not shown), a rack 93 for line-wise movement of the magazine 77. An eccentric disc 53 attached to the camshaft 50 operates through a rod 69 and linkages 70, 71 and 72 the pawl 74, Fig. 1, to drive the ratchet-wheel 66. The pawl initially rides over the cover-plate 68 before engaging the ratchet wheel 66 so that the magazine is moved line-wise by a length equal to the breadth of the character photographed. Variable line spacing is achieved with a ratchet 109, Fig. 13 (not shown), operating through gears to drive the spool of the film in the magazine 77. A manually adjustable cover-plate 115 is provided with a hand lever 114 for setting the amount of line spacing. A drive pawl 111 is attached to a hand lever 110 and -rides over the cover-plate 115 before engaging the ratchet wheel 109. Various character point sizes are achieved by changing the lens in the tube 42. The point size changes are accommodated in the line-wise movement of the film by the various gears shown in Fig. 6. Only one intermediate gear 88 is interposed between gear 90 and one of the gears 84 of different pitches for a particular point size.

Abstract: 1,015,948. Bending; twisting. SHEFFIELD CORPORATION. Aug. 4, 1964 [Aug. 1, 1963], No. 31299/64. Heading B3E. Apparatus for bending a work-press, e.g. a turbine blade, to the correct form includes means to clamp the workpiece at a first location thereon to rigidly locate it relative to a base, a head assembly mounted on the base for free movement about two intersecting perpendicular axes, holding means on the head assembly to hold the workpiece at a location spaced from the first location so that the head is positioned according to workpiece configuration between the clamping means and the holding means, gauging means for measuring the consequent orientation about the two axes of the head assembly relative to the base, and power means responsive to the gauging means acting on the head assembly to apply bending forces to the workpiece about the axes to bend the workpiece to the desired form. A turbine blade 10 whose form is to be corrected is first clamped at an adjustable location 9a, Fig. 1 (not shown) by jaws 17, 18. The jaw 17 is moved down to clamp the blade by link means 52, 54, 55, Fig. 3 (not shown), connected to an hydraulic actuator 62. The jaw 18 is moved to or from an operative position, about a pivot 47, by an hydraulic actuator 40. The root end portion of the blade 10 is held between jaws 22, 23, on a head assembly 11, the jaw 22 being moved down to hold the blade by link means connected through a screw 82 and a gear train 80 to a rotary hydraulic actuator 84. The head 11 is mounted for rotation about three mutually perpendicular axes intersecting at 24, Fig. 6 (not shown), so that twist, bending in a horizontal plane and bending in a vertical plane may be corrected. Deviation of twist from the required amount is detected by gauging means 25 caused by a ring 113 adjustably connected to the base 12 in a position determined by the value of the correct degree of twist. The gauging means 25 include, Fig. 8 (not shown), a movable plunger 124 engaging a plate 123 on the head 11, movement of the plunger 124 relative to a stop 121 signalling the amount of twist desired to control system which causes power means including a rotary actuator 30 to rotate the head 11 about the longitudinal axis of the blade to give it the desired twist. Deviation in respect of horizontal and vertical bending of the blade is detected by gauging means 26, 27 respectively bearing on the head 11. The amount of bend correction desired is signalled to a control system which causes a pair of actuators 31 to rock the head 11 about a horizontal axis, and a pair of actuators 32 to rock the head 11 about a vertical axis to apply the requisite corrective bending forces. Each actuator 31, 32 has a rod end 85, 87 carrying rollers 91 engaging interior surfaces of the head 11. Having corrected the blade when clamped at 9a, it is released at 9a, and clamped at 9b where it is gauged and corrected. Similarly for locations 9c, 9d. The whole correcting operation is controlled by a programme fed into the control system before the machine is started.

Title: Improvements in vehicle transmissions
IPC: F16H61/462
Filed: 1964-08-04
Abstract: 1,011,700. Hydrostatic transmissions. ROBERT BOSCH G.m.b.H. Aug. 4, 1964 [July 25, 1963], No. 31022/64. Heading F2D. In a vehicle transmission including an hydrostatic gear unit and centrifugal regulators for controlling the engine fuel pump and the gear unit respectively, the accelerator pedal is so coupled to the regulators that during its movement it is first effective only on the engine regulator, then on both the engine regulator and the loading spring of the gear regulator, and finally only on the gear regulator loading spring. In the arrangement shown, an engine 1, fitted with an injection fuel pump 2 is coupled by a shaft 11 and clutch 13 to the pump 4 of a swash plate type pump and motor gear unit 4, 5, controlled by an hydraulic regulator 6 comprising a piston 39 loaded by a centering spring 45 and connected to a servo control valve 60 connected to the gear unit swash plate 52 by a linkage 51. The gear regulator 7 comprises a pressure-control valve 18 connected to the servo unit 6 through a forward and reverse selector valve 32. Valve 18 is controlled by a loading spring 24 and a centrifugal regulator 7, of which the balls 28 are driven by a disc 27 geared to the engine shaft 11. An engine-driven centrifugal governor 8 is coupled to the fuel pump 2 by a link 71. The accelerator pedal 15 operates a by-pass valve 86 and a stirrup 80 bearing aginst cams 79, 83, the former of which is coupled to link 71 by a linkage 75, 76, 77, while the latter operates a rod 85 connected to a crank lever 26 engaging the loading spring 24 of gear regulator 7. Cam 83 may also be operated independently by a brake pedal 95 and push-rod 94. Operation.-Initial movement of accelerator pecal 15 causes operation of fuel pump 2 by cam 79 and linkage 75, 76, 77, but rod 85 bears against a horizontal portion 83<SP>1</SP> of cam 83 and so is not affected. Centrifugal regulator 7 acts upon pressure regulating valve 18 to raise the control pressure to operate piston 39 and so tilt swash plate 52 to initiate functioning of the gear unit 4, 5. Upon further movement of pedal 15 cam 83 becomes effective to vary the loading of spring 24, but over the final stage of movement of the pedal the horizontal portion 79<SP>1</SP> of cam 79 renders the latter ineffective upon the fuel pump 2, but cam 83 is still operative upon loading spring 24. With pedal 15 released, operation of brake pedal 95 causes displacement of cam 83 so that the loading of spring 24 is controlled by crank lever 26 whereby the ratio of the gear unit is adjusted to conform to the engine braking torque.
