Abstract: 1,143,138. Optical apparatus. HUGHES AIRCRAFT CO. Oct. 10, 1966 [Nov. 1, 1965], No. 45108/66. Heading G2J. [Also in Division H1] A laser is associated with an alignment microscope and means are provided for determining respective focal planes for the laser beam and for the microscope light path, the relative displacement between the focal planes being adjustable by controlling an optical system in the light path of the microscope and not in that of the laser beam. An enclosure 49 is mounted on a housing for vertical movement in response to rotation of a lead screw. The housing contains a laser, the output beam from which is deflected by a dichroic mirror beam splitter 51 to pass through an objective lens 72. The mirror 51 is transparent to radiation at wavelengths other than that of the laser beam and so transmits light from object 76 through optical system 86 Fig.5 to microscope eye-pieces 82. The optical system includes a reticle 92, lens system 96 and a movable lens holder 98. The lens holder is mounted for vertical non-rotary movement in response to rotation of a focusing cam having adjustable cam surfaces 111, 112, and is biased downwards by a spring 103. If the lens holder is adjusted so that the focal plane for the microscope is above or below that for the laser beam, when the microscope is focused on object 76 the laser beam is focused to a point such as 75 and the laser energy is directed on to a spot of known diameter on the object. If the focal planes coincide the laser beam impinges on the object with minimum spread and maximum energy.

Abstract: 1,270,667. Photo-electric head-lamp dipping system. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept.18, 1969 [Oct. 1, 1968], No.46450/68. Heading G1A A vehicle head-lamp system in which one shutter of a pair of shutters is moved in front of the headlamp beam in response to the detection of light from an oncoming vehicle, is adapted for use both in countries having a left hand rule of the road and countries having a right hand rule of the road. Light from an oncoming vehicle is focussed by a lens 19 into an aperture 22 and by a lens 24 on to a photo-cell 25. The cell's output is amplified and applied to windings 30, of a carriage 29 mounted on a limb 27a of a rectangular steel frame 27. The steel frame 27 includes a magnet 28 such that the magnetic field is at right angles to limb 27a. This will cause movement of the carriage 29, which carries shutters 41, 42, 43, and, in such a direction that one of the shutters cuts-off part of the head-lamp beam from filament 12. The direction of movement of the shutters is selected in dependence upon the rule of the road of the country and is chosen by a selector switch which will reverse the direction of current flow from the photo-cell. The movement of the shutters continues until a equilibrium position is reached with the leading edge of shutter 41 or 42 (depending on the direction of movement) at a position corresponding to the image in the aperture 22. The carriage is urged into a central position by a pair of leafsprings 44, 45 on either side of the carriage and connected thereto by a self supporting filament 46. The ends of filament 46 pass through holes in the leaf-springs and are connected to studs 47, as shown; thus when the carriage moves only one of the leaf-springs is stressed, the filament 46 sliding through the other.

Abstract: 1,168,271. Hydro-mechanical variable-ratio gear. SUNDSTRAND CORP. 19 Oct., 1966 [21 Feb., 1966], No. 46832/66. Heading F2D. A variable-ratio gear comprises an output sun 43, a planet carrier 45 clutchable to an input shaft 11 by a clutch 16 and connectible, by a clutch ] 7, to a ring gear 41 which is connected to a constant displacement hydrostatic unit 21 in hydraulic communication with a variable displacement hydrostatic pump unit 20 driven by the input shaft. The units may both be of the swash-plate type. For a low speed range the clutch 16 is disengaged and the clutch 17 engaged, so that the drive is all hydraulic and the output speed is increased as the displacement of pump unit 20 is increased from an initial zero position. In its maximum displacement position 25, the pump swash-plate 23 depresses a switch 55 to disengage the clutch 17 and engage the clutch 16. A split-torque drive ensues, the output speed increasing further as the displacement of pump 21 is reduced from its initial maximum position through neutral to its reverse maximum stroke position 26. The switch 55 is of the type adapted upon depression and release to assume one condition and retain it, and upon a successive depression and release to assume the other condition and retain it, so that on changing the pump swash-plate back to its first maximum stroke position the switch 55 when actuated disengages clutch 16 and engages clutch 17 to restore the low speed all hydraulic phase. All hydraulic reverse is obtained with the clutch 17 engaged and clutch 16 disengaged and the swash-plate 23 shifted to the reverse side of neutral.

The frame is in two parts 2, 3, the upper part 3 being hinged at 4 to its associated piston 5, and rotatable away from the bolster and roll by light jacks 11. The two parts are connected only by the roll and bolster, and to equalize the displacements of the upper and lower parts of the bolster, pressure fluid supply to the upper cylinder is controlled by a switch 20 operated by lever 8 and abutment 25 so that the upper part, which may lag behind the lower, is driven until it catches up. The total bending stroke is terminated by switch 23 operated by abutment 24 on the lower cylinder. The plate is fed by driving roll 9 by gear 16 and rack 15, the roll being locked during bending by rack 15a. Rolls 10c on the bolster facilitate plate feed. Fig. 5 shows an embodiment in which the abutments 10a, 10b are adjustable laterally, by release of the abutments from surfaces 31 by jacks 33, followed by traverse of the abutments by lead screw 36, and re-engagement of the abutments with surfaces 31, whereby the bending moment on one side of the plate may be increased to facilitate bending the end of a plate. An hydraulic intensifier (see Division F1) may be added to the fluid pressure supply for the rams and used only when required.

Abstract: 1319609 Mountings for magnetic heads HONEYWELL Inc 9 Oct 1970 [14 Jan 1970] 48187/70 Heading G5R [Also in Division B3] A method for producing an article, such as the slider of a magnetic recording head, having a compound curved surface from a relatively flat blank comprises forming the inverse of a desired curvature on an abrading surface, moving the blank in contact with the surface in a first direction, and reciprocating the blank in a second direction transverse to the first direction. In an alternative method, a flat blank is resiliently deformed within its elastic limit to form the converse of the compound surface, and one side is abraded with a planar abrading surface while the blank is deformed so that when the blank is released it has the desired compound surface. In the first method, the slider 5, Fig. 1, is circular and has a portion with two parallel edges 6, the portion being recessed to receive a magnetic core element 9 which follows an information track 17 on a data storage disc 1. A thin sheet material 21, Fig. 3, such as glass, ceramic coated steel, or stainless steel, which forms a lapping surface is supported on a backing plate 20 so as to be curved in both the X and Y directions and the slider reciprocated over the surface at a fairly rapid rate in the X direction and at a slower rate in the Y direction in the presence of a lapping paste or slurry until it has a compound curved or saddle-shaped surface. A number of sliders may be mounted on a disc for simultaneous lapping. In the alternative method, a flat slider is gripped between the arms 40, Fig. 6, of a clamp 30, so as to be resiliently deformed to the inverse of the compound surface required, and the deformed surface is lapped on a flat plate to the level 42, Fig. 8, so that when the slider is released from the clamp and returns to its unstressed condition it has a compound curved or saddle-shaped surface.
