Title: Controlled system for focussing a read-out light beam
IPC: G11B7/005
Filed: 1974-11-13
Abstract: 1441358 Automatic control of focus and position THOMSON-BRANDT 13 Nov 1974 [16 Nov 1973] 49188/74 Heading G3R The focus of a read-out light beam on a moving substrate 4 carrying data (e.g. a television signal) is automatically controlled by a system in which an objective lens 21 is continuously reciprocated by a "pilot" signal (from generator 30), the resulting modulation of the information signal being detected at 6 and compared at 7 with the pilot signal to produce a focus error signal which is used to correct the focus (by adjustment of the mean position of the reciprocating motion). The pilot signal is preferably sinusoidal and the comparator 7 produces a D.C. signal of a polarity and magnitude corresponding to the phase relationship between its inputs. It is explained that the phase of the detected signal depends upon amount and direction of the focus error Fig. 2 (not shown). A phase shifter 20 in the pilot signal channel provides compensation for inherent phase shifts in the system. During initial positioning of the lens the detected signal is below a threshold; this causes a relay 9 to switch out the control signal and focus is achieved manually by adjustment of a D.C. source 40. In alternative embodiments the record has a reflecting information surface Fig. 3 (not shown), or the lens may have a fixed element in addition to the movable one Fig. 4 (not shown). It is stated that the same system can additionally control central positioning.

Abstract: 1,079,498. Electrical control of shutters. AGFA A. G. Dec. 10, 1964 [Dec. 10, 1963], No.50381/64. Heading G2A. A shutter mechanism in an optical printer has a blade 11 pivoted for movement in a light beam by means of a rotary electromagnet 15, the blade being pivoted on an axis parallel to and spaced from the optical axis of the associated lens system Fig.3 (not shown). The magnet is energized at the beginning of an exposure, thus transmitting axial and rotary movement to its armature 16, the rotary movement being further transmitted to a spindle 20 and a shutter spindle 32 thus causing the shutter to rotate. The spindle 32 rotates in a brake disc 40 until a pin on the spindle contacts the sides of a slot in the disc Fig. 7 (not shown), when the brake disc also rotates, the spindle being slowed by a spring 41 and a friction lining 43. The spindle and brake disc are brought to rest when a dog (37) contacts the surfaces of a plate (36) Fig. 6 (not shown). However, the spindle 20 continues to rotate, causing balls 26, 27 to be forced out of notches (28), (29), Fig. 5 (not shown), and into notches (30), (31) at which time the action of friction between the ball catches (26), (27) and a surface (23) has almost brought the spindle 20 to rest. The angle of rotation of the electromagnet is approximately 45 greater than that of the shutter blade. The magnet 15 is deenergized by a signal from an exposure regulating device (not shown) and a return spring (not shown) sets the armature 16 in motion towards the initial position. The brake 40 again remains out of engagement with the spindle 32 for the first part of the motion, the spindle being brought to rest when the dog 37 meets the other impact surfaces of the plate 36. The ball catches return to the depressions (28), (29).

Abstract: 1499319 Boring machines; setting devices CARSHALTON REBORE SERVICE Ltd 20 Feb 1976 [22 Nov 1974] 50724/74 Headings B3C and B3B A machining apparatus, such as the illustrated engine cylinder re-borer, has two machining tools 29 for simultaneously machining the workpiece at two locations (two cylinder bores) spaced a fixed distance apart. Initially, a workpiece carrier plate 33 is positioned on a platform 10, as shown in Figs. 1 and 2, abutting a stop 35. The workpiece, cylinder block 39, is positioned on the plate so that its second cylinder bore is approximately aligned with the centring head 16 of a positioning device 14 which is fixed to platform 10 and spaced a predetermined distance from a first boring device 28 also fixed to platform 10. The centring device 25 of a second positioning device 22, movable under platform 10 by means of plate 23 on rollers 26, is then approximately aligned with the fourth cylinder bore. The heads 16, 25 are then extended upwardly into the cylinder bores, by pneumatic piston means, not shown, through aligned slots 11, 34 in platform 10 and carrier plate 33, and radially extensible jaws 18 20 on each head, Fig. 2, are pneumatically displaced into engagement with the cylinder bore walls. This has the effect of automatically spacing the tool carrying heads or devices 28, 31, since the second device 31 is mounted on the movable plate at the same predetermined spacing from positioning device 22 as that between the first boring device 28 and positioning device 14. The workpiece is then clamped to carrier plate 33 and the plate 23 is clamped to platform 10, both being clamped by respective pneumaticallyoperated clamping means (not shown). Centring heads 16, 25 are retracted from the cylinder bores and carrier plate 33 is moved along the platform, e.g. on an air cushion, until it abuts a stop 36 and the slot overlies exactly a second slot 12 in the platform above tools 29. The carrier plate is clamped to the platform by pneumatically-operated clamping means (not shown) and boring by the hydraulically operated devices 28 and 31 can commence. After the boring of the second and fourth cylinder bores is completed, stop 36 is removed and the carrier plate is undamped and moved into abutment with stop 37 which is spaced a distance from stop 36 corresponding to the spacing between adjacent cylinder bore centres so that, after re-clamping plate 33, the first and third bores may be machined.
