Title: Magnetic directing mechanisms for articles
IPC: B65G17/00
Filed: 1972-06-09
Abstract: 1404343 Separating by weight HI-SPEED CHECKWEIGHER CO Inc 9 June 1972 [9 June 1971] 27128/72 Heading G1W [Also in Division B8] Article carriers 36 slidably supported on rods 20 of an endless chain conveyer are controlled by a magnetic device 10, Figs. 1, 2, which includes a pair of selectively operable electromagnets 56 and a pair of elongated permanent magnets 54 which provide guide surfaces 68 for rollers 42 of the carriers 36; the diameter of the rollers 42 corresponds to the spacing between upstream surface portion 78a of the electromagnets 56. The spacing between surfaces 68a of the permanent magnets 54 is such that, if the electromagnets 56 are not energized, a roller 42, together with its carrier 36, continues to pass centrally of the magnets 56, 54. Energization of one or other of the electromagnets 56 causes a carrier to move laterally in the region of the magnets 56 and then to continue thus due to the action of one or other of the magnets 54. Depending on the operation/non-operation of the electromagnets 56 the carriers 36 move to regions A, B or C at the delivery end of the conveyer. The magnets 56 may be controlled by any suitable device but as shown, a weighing apparatus having a conveyer 82 determines to which region articles on the carriers are delivered. Those carriers which are deflected to regions A or B are centralized by engagement of their rollers 42 with elongated cam elements 48 during the return run of the carriers. In modifications, Figs. 6, 7 (not shown), by providing further downstream electromagnets and permanent magnets, articles from a single input line may be separated into four or five output lines. In a further modification, Fig. 9, the downstream diverting electromagnets of (Figs. 6, 7) are replaced by pneumatically operated separators 100 which, when their piston-rods 104 are extended, cause the engaged roller 42 to break away from the magnet 54. In Fig. 10, a rotary solenoid 102 of a separator 100' has an L-shaped arm 106' for engaging a roller 42. The separators of both embodiments are adjustably mounted on bars 110, 110'. In a still further embodiment, Fig. 11, carrier conveyer 200 is used to bring into a single output line three input lines 202a-c. The conveyer 200 is identical to that of Fig. 1 except that it is inverted and the electromagnets 56 are used to divert carriers on their lower, return run to line 202a or line 202c. Groups of carriers may be used to support each article and gates 210, 212 may be used to form groups of the articles. An electrical memory unit 220, a cam timer (224) and a control circuit (222), Fig. 12 (not shown), control the device 10 and the gates 210, 212 in timed sequence.

Title: Servo apparatus
IPC: G05D13/62
Filed: 1976-06-30
Abstract: 1499268 Automatic control systems INTERNATIONAL BUSINESS MACHINES CORP 30 June 1976 27317/76 Headings G3N and G3R A servosystem, for automatically positioning, during a track following mode, a transducer relative to a track on a movable record medium e.g. a disc, also controls the transducer velocity during a track access mode. During this latter mode, signals from the transducer are sampled, by a transducer position control, at times which coincide with the times that the transducer moves across a respective track. The transducer position error thus derived from  the sampled signals is used to vary the transducer velocity. As shown, the system is used with a magnetic or optical disc 1 having concentric tracks 6, a playbackread head 3 and a further head 7 detecting pulses on a timing track 8. During a data sector read and track following mode, whenever timing signals from 7 are received by a control unit 14, a head position error signal is gated via 16, lead-lag compensator 19 and transistor switch 20a to a head actuator 4. This moves the head relative to the track to reduce the position error. This error is inverted at 16 for alternate tracks. During a track access mode, signals from a control unit 23 e.g. a CPU to control unit 14 are dependent upon the direction of the head movement and the desired track number. Provided the head is not accelerating or decelerating, the head position error is derived by sampling every other servo sector on the track. The timing pulses from 7 are used to sample the position error such that the position control loop sees only the instantaneous position at the sampling time of the transducer relative to a respective track, as it crosses that track. The resultant position error is used to vary the head velocity so as to reduce the position error, and thus to regulate the velocity. During the access mode, the lead component of compensator 19 is changed. The control unit 14 (also Fig. 4, not shown) includes logic elements and two counters to count the tracks crossed and control acceleration, constant velocity or deceleration portions of the transducer speed profile during the access mode.

Abstract: 729,489. Stopping shafts in predetermined positions. MINISTER OF SUPPLY. Oct. 29, 1953 [Oct. 30, 1952], No. 27344/52. Class 80 (2). A radio-tune or other shaft 11 is stopped in pre-selected positions by engagement of a selected one of twelve stop-pawls (Fig. 11, not shown) with one each of two sets of stop members, both carried on the shaft 11, one set. 35 ... 46 rotating fast with the shaft, whilst the other" set 63 ... 74 is driven at a slower speed through gearing by the first set. The system is otherwise the same as that in Specification 612,315, wherein the stop-pawls are pivoted side-by-side on a common shaft and engage at on end cam discs on a pre-selector shaft parallel to the shaft 11 which permit a selected stop-pawl to pivot under spring-load whereby a tooth on its other end may enter a notch in the selected stop-member on the shaft 11 to stop the latter and switch off the driving motor. In this case, the pawl-tooth first engages a slot 76, Fig. 8b, in the selected one of the outer set of slowly rotating stop-members 63 ..'. 74, but can only pass through the slot 76 to engage a notch 47, Fig. 6a, in the underlying fast stop disc 35 ... 46 when the slot 76 and the notch 47 both come into registry under the pawl tooth, which can then enter the slot and notch to stop the shaft. This condition may require several revolutions. The fast stop discs 35 ... 46 are secured frictionally on the shaft 11 between pinned-end members 18, 19, one, 18, axially fixed, the other, 19, axially free and releasably loaded through a cam 97 and tappet 106 to apply clamping pressure through a diaphragm spring 112 and spigoted spacers 20 ... 31, slidable on a squared section 16 of the shaft 11.. The slow stop-members 63 ... 74, together with interposed toothed discs 48 ... 60 are clamped by the same endpressure, now acting through a light spring. 111 and ball-thrust bearings 110, 109, which latter permit independent rotation of this assembly which is driven slowly through a stepped wheel, not shown, connecting a pinion 81 on the shaftmember 18 with the toothed discs 48 ... 60. The shaft 11 is itself motor-driven through a toothed wheel 107 on the shaft-member 18 and can also be turned by a hand-knob 88 with dial 90, as for circumferential adjustment of the individual stop members after release by the cam 97 of the clamping pressure.

Abstract: 537,859. Air bombs. MUNITIONS, Inc. Oct. 6, 1939, No. 27358. Convention date, Oct. 15, 1938. [Classes 9 (i) and 9 (ii)] A bomb of shrapnel type, for explosion without substantial penetration into the ground, comprises an outer casing B, Figs. 1, 2, within which the bomb-proper A is retained at the front or lower end until impact occurs. A protruding striker 49 is then driven in and a cartridge 37 is fired which propels the bomb-proper upwardly in the casing on to a detonator C at the rear end thereof. The bomb-proper is normally retained at the front end of the casing by a telescoping tail 56 which is housed within the casing until the bomb is released from the bomb-rack. The nose of the bomb comprises a wooden member 33 within a cavity of which is the cartridge 37, and percussion cap 41, carried by the striker or plunger 49 which is provided with a nose cap 53. Spaced from the member 33 by a deformable lead sealing pipe 54 is the bomb A having wooden end plugs 18, 23 between which is the main explosive charge 21 and surrounding slugs or pellets 22. A fuse cord 26 extends through the centre of the charge 21 from a metal grille 24' at the rear end of the bomb. Normally, the plunger 49 is held in the projection position by a safety clip 75, Fig. 3, and the bomb A is held against the pipe 54 by a spring 62 which is compressed between the rear end of the bomb and the forward end of the bomb-guiding means or tail which comprises end plates 58, 59 and longitudinally extending sheet-metal blades 56, Fig. 10. A safety pin 71 retains the tail in this housed position. A bracket 63 fixed diametrically across the bomb casing B between the blades 56 carries the detonator C. When the bomb is supported beneath an aircraft 83, Fig. 13, a two-armed forward bracket 84 takes the place of the safety clip 75 and a rear bracket 95 keeps the tail within the bomb casing B, the safety pin 71 having been removed. The bomb-releasing means comprises two hinged clamping arms 85 operable by a rod 94 through a lever linkage. As the bomb leaves the rack, the tail is projected under the action of the spring 62 until halted by the engagement of the end 59 with the bracket 63. On striking the target, the striker 49 thrusts the cartridge 37 against the underside of the bomb A where it is exploded, the explosion causing the bomb to be driven upwardly along the casing B into contact with the detonator C, which fires the main charge 21, through the fuze cord 26.
