A work-holding apparatus for holding a workpiece 13, Fig. 1, having an annular internal surface comprises a gripper body 10 having a generally annular surface which is adapted to mate with the internal surface of the workpiece and has circumferential groove means 21 therein, a vacuum actuated piston means 26, passage means 15, 18 connecting the groove means and piston means to a source of vacuum, and mechanical means 25 movable by the piston means to exert holding forces on the workpiece placed over the gripper body, the groove means being adapted to be sealed from the atmosphere by the workpiece to form a vacuum chamber accommodating the exertion of a holding force on the workpiece. upon connection of the passage means to a source of vacuum whereby the workpiece is held by a combination of mechanical and vacuum forces. As shown, the gripper body 10 has three grooves 21, 22, 23 which are connected by passages 18, 19, 20 to the passage 15 connectable to the vacuum source. The passage 15 also communicates with a recess 17 for a pin 26 which is secured to the mechanical means 25 in the form of a piston-like plate having a shoulder 27 for engagement with the internal wall of the workpiece and an O-ring 29 for sealing a vacuum chamber 31. In operation, the workpiece, which may be a rocket part, such as a nozzle skirt, is placed over the body and the plate applied over the end of the body, a knob 30 facilitating this operation. When vacuum is applied to the passage 15, it acts in the chamber 31 so that the plate 25 acts like a piston to press the workpiece on to the body 10 sealing the grooves from atmosphere to permit the vacuum to act in the grooves to also hold the workpiece on the body. In another embodiment for holding a workpiece 51, Fig. 2, in the form of a nozzle cone of a rocket, the gripper body 56 comprises an upper part 57 having a plurality of grooves 58 connected by passages 59 to a further passage 60 connectable to a vacuum source, and a lower part 55 in the form of a piston slidable in a cylindrical recess 71 in an upstanding part 54 mounted on a base 53. The lower portion of the upper part 57 and the lower part of the part 54 are formed with oppositely-inclined tapered surfaces 63, 64 which are engaged by a plurality of cylindrical segments 65 urged radially inward by a spring 66; a spring 72 also acts on the piston 55 to separate the surfaces 63, 64. The ends of the portion 57 have 0-rings 61, 62 for sealingly engaging the workpiece and surface of the body 56 so that when the vacuum source is connected to the passage 60, the workpiece is first held on the body by the vacuum forces in the grooves 58, the vacuum then acting in the chamber 71 to draw the piston 55 downwardly to move the tapered surface 63 towards the surface 64 so that the segments 65 are urged outwardly to grip the workpiece. The vacuum may be supplied to the base 53 of the chuck.

Title: Dual Scale Interval Timer
IPC: G04F3/02
Filed: 1967-02-07
Abstract: 1,165,956. Alarm interval timers. GENERAL ELECTRIC CO. Feb.7, 1967 [March 10, 1966], No.5777/67. Heading G3T. An interval timer comprises a rotatable interval indicating hand 26 attached by a shaft 32 to a partially toothed gear 62 and a pair of driving pinions 64, 65 successively meshing with the teeth 63 of the gear, the pinions being rotated at different speeds to drive the hand from a selected time interval position on a first scale marked 0-30 minutes or on a second scale marked 30 minutes-4 hours, the pinion 65 driving the gear 62 when the hand coincides with the second scale and the pinion 64 driving the gear 62 when the hand coincides with the first scale. Accurate timing of an interval of less than thirty minutes can be achieved whilst timing intervals of up to four and a half hours can also be accommodated with the compressed second scale. A synchronous clock motor 39 is mounted below a base plate 34 and has an output shaft 40 attached to which is a pinion 42 for driving a minutes gear train 35 comprises gears 43, 44, 46, 47, 49. The gear 49 drives a minutes shaft 27 and a minutes hand 24. An hours gear train 36 comprises gears 52, 53, 54, 56, the gear 52 being attached to the shaft 27. The gear 56 rotates an hours hand shaft 28 and an hours hand 23. The hours and minutes hands co-operate with a twelve hour dial concentric with the first and second dials on a plate 22. These hands are set by depressing and rotating a knob 25 so that projections 58 on a shaft 57 engage notches 59 in an extension 29 of the minutes shaft 27. On releasing the downward pressure on the knob 25, a leaf spring 37 engaging the lower end of the shaft 32 biases this shaft and the knob back to their original positions. The pinions 64, 65 are driven via friction clutches 67, 68 respectively so that the hand 26 may be rotated to the selected time interval indication without the resulting rotation of the pinions 64, 65 by the gear 62 causing rotation of the minutes or hours gear trains. Shafts 48, 66 on which the pinions 64, 65 are mounted, have their lower ends located on spring-loaded levers 100, 109 respectively so that the pinions are baised into engagement with the teeth 63 yet there is also sufficient play to enable the momentary engagement of both pinions with the teeth 63 at the thirty minute position of the hand 26. As the timing proceeds, the hand 26 rotates clockwise until it reaches the mark '0' on the dial whereupon both pinions 64, 65 are disengaged from the teeth 63 and the gear 62 is therefore stationary. At this instant a notch 95 on a cam 93 aligns with a projection 96 on a latch 86 which restrains a vibrator 79. The latch releases the vibrator which vibrates under the influence of the field of the synchronous motor frame 84 to produce an audible buzz. To stop the alarm, the hand 26 is manually rotated to the 'OFF' position and the projector 96 moves out of the notch 95 so that the latch again restrains the vibrator.

[Class 78 (iii)] [Also in Group XXI] A scraper for excavating earth comprises an earth-receiving bowl in two parts adapted to slide telescopically one in the other. A tail gate is movable forwardly through the bowls to discharge the spoil. The main frame comprises parallel beams 1, 2 to which the front bowl 3, with cutting edge B, is rigidly fixed, opposite beams 1 being connected by a hollow beam 4. A front truck 8, adapted for connection to a tractor, includes arms 9 pivoted to the main frame at 10. A pivoted push bar 14, connected to the main frame and carrying pulleys 17, is slidably supported by a member 15 carried by the front truck and carrying pulleys 16 ; by hauling on a cable 19 passing between pulleys 16, 17, the front bowl 3 is raised from the ground. A rear bowl 22 with reinforcing beams 26, 27, 29, Fig. 9, is slidably supported on the beams 1, by beams 24 and rollers 25 to telescope within the bowl 3, both bowls being backless. A tail gate 30 is connected to a hollow beam 31 secured to longitudinal beams 32 guided on the main frame by rollers 33, 34, 36, 37, Fig. 6. An apron 38, adapted to fit against the front bowl, is supported by arms 39 pivoted to the main frame. A cable 40 extends over a pulley 43 on the apron 38, then over a pulley 44 to pulleys 45, 46, on opposite sides of the main frame and tail gate respectively. The spoil is discharged from the bowls by drawing in the cable 40 which first lifts the apron 38 to contact a stop 47, and then advances the tail gate, the rear bowl 22 advancing therewith owing to its load; at the end of the advance of the rear bowl, latches 48 thereon engage stops 49 on the main frame, and the tail gate completes discharge of spoil. During the advance of the tail gate, springs 50, Fig. 3, within the hollow beams 4, 31, carried by the main frame and tail gate, are compressed by cable 54, fixed at its ends to the beams and passing over pulleys 53, 52, carried respectively by the beams 4, 31 and by slidable members bearing on the springs; on releasing the cable 40, the springs first retract the tail gate until stops 55 thereon trip the latches 48 and the tail gate then engages beams 26 on the rear bowl to move the latter rearwardly. When beginning to load the scraper, the rear bowl is preferably in advanced position. In another form, Fig. 13, the return is effected by a single spring 57 arranged in a central beam 13a and connected by cable 60 to a drum 61 fixed to a spiral drum 63 connected by cable 62 to the tail gate.
