Title: Improvements in or relating to automatic feelers or tracers for copying machine tools
IPC: B23Q35/123
Filed: 1968-10-24
Abstract: 1,218,376. Copy-machining. STARRFRASMASCHINEN A.G. 24 Oct., 1968 [27 Nov., 1967], No. 50612/68. Heading B3K. [Also in Division G3] An automatic tracer head for a copying machine tool having a tracer 5, 11, arranged to be axially movable and mounted to pivot and having a precontrol unit acting to bias the tracer in a given direction in the copying plane is provided also with a sensing device 8, 9 which responds to lateral deflections of the tracer, i.e. deflections outside the copying plane, which may be caused by the wedging action of a sloping and angled sidewall 34 of the template being copied, the sensing device 8, 9 being coupled to a correcting unit 30, 2, 4 which co-operates with or acts against the precontrol unit to deflect the tracer (e.g. in the case shown, upwardly) in a direction to eliminate the lateral deflection. Signals from the sensing device 8, 9 are used through solenoid 4 to displace the lever 30 against the tracer head 12 thereby displacing the precontrol pressure roller 13 which is disposed opposite the lever 30. In result the precontrol head is rotated by the motor 16 and the tracer adopts a new course till equilibrium of the precontrol head is again reached and the tracer again lies in the copying plane in contact with the template. In a first modification (Fig. 6, not shown) two levers (48, 49) operable on the tracer head (12) alternatively according to the tracing direction, are provided, the levers being arranged symmetrically with respect to the precontrol pressure roller (13). In a third embodiment (Fig. 11, not shown) a threshold value switch is controlled by an electromechanical transducer (74) responsive to lateral deflections of the tracer which brings a comparison circuit into operation whereby the instantaneous position of the precontrol unit is compared with the signal from the sensing unit (9) and the tracer is correspondingly deflected. In a fourth embodiment (Fig. 23, not shown) the signal indicating lateral deflections is used to move the normally stationary coil (22) of an electromechanical transducer forming part of the precontrol unit. In a fifth embodiment (Figs. 26-28, not shown) two proportionally acting solenoids (85, 87) are attached directly to the tracer at an angle to its axis, one or the other solenoid being energized above a threshold value of the lateral deflection in dependence upon the tracing direction.

The rod 2 may, however, be driven with the spiral 3, Fig. 2 (not shown), or float freely, Fig. 4 (not shown). In all cases the diameter of the wire forming the spiral 3 is equal to the difference between the radii of the casing 1 and the rod 2, with a small clearance, Fig. 3 (not shown).

Title: Transducing head steering system

Filed: 1974-11-27
Abstract: 1447816 Automatic control of position INTERNATIONAL BUSINESS MACHINES CORP 27 Nov 1974 51373/74 Heading G3R In a system for maintaining a transducer head 16 centred between adjacent tracks 3, 4 of different servo signal records by adjusting its position in response to a comparison of the resulting servo signals, at periodic intervals along the tracks the normal control is suspended and the recorded signals are altered to generate 100% off track indications in each direction sequentially and the consequential signals to the comparator are equalized. The object is to periodically (once per revolution of a disc record) correct any drift in the control circuits. Adjacent tracks carry signals at different frequencies Fl and F2 which are separated by filters 23, 24 Fig.2 at the transducer 16 output and applied to a comparator 27 in one channel via a variable gain amplifier 31. Periodically the signal Fl is recorded in both channels at 51  followed by F2 in both channels at 52. Thus the transducer output corresponds to it being 100% off track in either direction sequentially. The resulting signals are supplied to sample and hold circuits 28, 29 and any difference causes adjustment of the gain of amplifier 31. The operation depends upon the fact that, since both tracks 3, 4 have the same signal at 51 and 52, any difference between these bands is due to imbalance between the channels and not head misalignment. The bands 51, 52 may be preceded by a blank sector which is detected at 33 to switch the system from its normal mode. The servo tracks may be on a separate disc from information tracks or recorded in a separate layer on the same disc Fig. 1 (not shown).

Unsaturated aliphatic aldehydes or aldehydes in which one or two-CHO groups are attached to a benzene or pyridine nucleus are obtained by oxidizing unsaturated aliphatic hydrocarbons containing at least one CH 3  group in the α-position relative to the double bond, or mono- or dimethyl-benzenes or -pyridines, in a homogeneous gas phase at 200 to 600 C., with molecular oxygen or molecular oxygen-containing gases and either simultaneously or subsequently with nitrous acid or its equilibrium mixture containing nitrous acid, N 2 O 3  and water vapour, in such quantities that the molecular oxygen is at most stoichiometrically equivalent to the CH 3  group or groups in the α-position relative to the carbon double bond or the-CH 3  groups in the mono- or dimethyl-benzene or -pyridine. It is preferred that the molecular oxygen used, e.g. in the form of air, and the oxygen in the form of gaseous nitrous acid is the exact stoichiometric equivalent of the CH 3  groups in the starting material to be oxidized. The nitrous acid or its equilibrium mixture with water vapour and N 2 O 3  may be obtained by oxidizing ammonia with oxygen and/or air and water vapour in the presence of noble metals, e.g. platinum/ rhodium, and/or of oxides of the heavy metals, e.g. iron, cobalt or molybdenum oxide, optionally containing bismuth oxide and the resulting nitrous acid gases may either themselves contain molecular oxygen resulting from the use of excess oxygen in the ammonia oxidation process or alternatively air or oxygen can be mixed with them. It is desirable to provide means for thoroughly mixing the reaction mixture both before and during the oxidation reaction to form the aldehyde and it is preferred to initiate the reaction at 220 to 280 C. and to carry out the oxidation at 300 to 450 C. Specified hydrocarbons and methyl pyridines which may be used are propylene, isobutylene, toluene, xylene and beta-picoline and a detailed example is given with the aid of a flow diagram for the oxidation of propylene to acrolein using a gas mixture prepared by addition of oxygen and water vapour to the gas mixture obtained by oxidation of ammonia with oxygen and water vapour using platinum/ rhodium gauzes at 800-900 C.
