Abstract: 1,039,179. Vehicle doors. BECKETT, LAYCOCK & WATKINSON Ltd. Oct. 9, 1964 [Oct. 31, 1963], No. 43093/63. Heading B7J. A " flush-type " sliding vehicle door is supported and controlled at its front end on an arm 10 rigidly attached to a vertical bearing member 9 which is pivotally mounted in the door, and at its back end by a pair of grooved pivotable wheels 5 running on opposite sides of the web of a T-section rail 6, the arm 10 having at its end remote from the door a forked portion 11 and is pivotally mounted in a U-shaped runner 12, this runner being movable in a direction parallel to the sill 17 of the door on a wheel 18 attached to a side flange 19 of the runner, the second side flange 20 being provided with a ball race 21 which co-operatea with a complementary race 22 fitted to a face 23 of the sill to prevent the runner tilting under the weight of the door. When moving the door from the open to the closed position the door first moves in a direction parallel to the sill 17 until the fork portion 11 of the arm 10 engages a stud 32 fixed to the sill. This engagement prevents any further movement of the door in the parallel direction but enables the front end of the door to pivot about the member 9 and the stud 32 thereby moving the front end of the door adjacent to the bodywork 3. The back end of the door may then be pushed into its final position so the door fits flush with the bodywork. Rotation of the arm 10 before it reaches the stud 32 is prevented by a latch member 26, Fig. 4, having a projection 27 which engages a cut-out 28 of the arm, the latch being released only by engagement with the stud.

Title: Photoelectric microscope
IPC: G01D5/30
Filed: 1965-10-19
Abstract: 1,094,230. Photo-electric line location. BAUSCH & LOMB Inc. Oct. 19, 1965 [Oct.21, 1964], No.44315/65. Heading G1A. In a photo-electric microscope, scanning means are used to locate a line on a scale with reference to the microscope axis. Light from a lamp 3 is projected on to a ground glass disc 4 which will provide uniform illuminatioh of the scale 1. The light is condensed (at 5) and reflected by a beam splitting plate 6, through the objective lens system which focuses the beam on to the scale 1. The light reflected includes a dark line representative of a scale line, and passes through the plate 6 to a further beam splitter 8. The latter permits the light from the scale to be observed visually through eyepiece system 9, to allow correct focusing of the system and alignment of the scale. The axis of the visual system provides the reference relative to which a scale line is to be located. Light from beam splitter 8 also passes to a focus in the plane of the scanning means, a wire 13 vibrating between the polepieces of a permanent magnet 12, slits being provided in the polepieces for passage of the beam which is focused by a lens 17 on to photo-cell 18. The photo-cell output signal is amplified (at 21) and then passed to a phase-sensitive demodulator 20 which compares its phase with that of a reference signal from the oscillator controlling vibration of the wire. The filtered output of the demodulator 20, is a positive or negative D. C. signal, representative of the deviation of the scale line from the neutral position of the wire 13, and also therefore from the optical axis of the microscope. The output is indicated by a null detector, which may be a D. C. voltmeter. A null reading is obtained when the scale line is aligned with the neutral position, but is also obtained when no scale line is visible in the field of view of the microscope. In order to indicate that a line is within the field, the fact is utilized that when the scale line is coincident with the neutral point, the photo-cell output has a frequency double that of the oscillator frequency. Part of the amplified photo-cell output is filtered at this doubled frequency (at 24) amplified (at 25) and applied to a multi-vibrator, which energizes a lamp or other signal indicator if the line is coincident with the neutral position, or very near it. In another arrangement, back lighting of a scale Fig. 3 (not shown) may be provided to give bright scale lines and dark spaces.

Abstract: 1,159,942. Laying cable forms. ELEKTROMAT VEB. 6 Oct., 1966, No. 44601/66. Heading H2C. In a machine for laying a cable form on an axially slidable and rotatably mounted wiring board 2 according to a laying plan, faulty feeding of the wire 5 to the board is automatically detected and wastage of wire prevented. As shown, one of the wires 5 to be laid is selected by moving the holder 10 carrying a roller 9 until the wire to be laid is located between roller 9 and a further roller 13. Motor 20 then drives roller 13 through worm mechanism 17, 18 to feed the wire down through an eccentrically rotatable laying finger 15 and a hole 4 in the board to the underside of the board where it is fixed. Motor 20 then stops. The finger 15 then rotates to wrap the wire around pin 3 drawing further wire under roller 13 which then transmits a drive to move worm 18 away from the worm-wheel 17 and to actuate switch 27 and start the co-ordinate movement of the board and the lifting of roller 13 from the wire. If the roller 13 is not driven, switch 27 is not actuated and no co-ordinate movement of the board occurs. Alternatively, the wires 5 may be gripped by pairs of springs (42) (Fig. 4, not shown.) mounted on a hinged holder 40 and during the feeding of the wire to the rotating finger the entire unit is tilted on to a switch (49) (which has the same function as switch 27) and the springs (42) may be forced apart by a tappet (43) operated by a rocker arm (46) driven by a solenoid (45).

Abstract: 1398605 Slide projectors EASTMAN KODAK CO 28 Sept 1972 [28 Sept 1971] 44830/72 Heading G2J A rotary slide magazine 2 can be moved in either direction by a single slide changing distance, or can be advanced through a greater distance to position any pre-selected slide in the projection position. As shown, for single slide changing, anti-clockwise movement, an electromagnet 29, Fig. 1, is energized to position a pin 5 such that when a first drive mechanism (not shown) reciprocates a lever 3, pin 5 deflects lever 3 to rotate a gear 13 anti-clockwise, and gear 13 moves magazine 2 by means of pins 2a. For single slide changing, clockwise movement, electromagnet 29 is kept de-energized and pin 5 adopts a position in which it deflects lever 3 to rotate gear 3 clockwise. For movement through a greater distance, an electromagnet 26, Fig.3, is energized to lower a bush 23 into driving engagement with a gear 19 which is driven, via a gear 20, by a second drive mechanism 22. Bush 23 rotates a shaft 18 and thereby rotates gear 13 to advance the magazine 2 to a selected position.
