Title: Centering means for a drill spindle
IPC: B23Q17/24
Filed: 1936-12-22
Abstract: 472,017. Drilling-jigs. LINDNER, H. Dec. 22, 1936, Nos. 35185 and 35186. Convention dates, May 14 and Aug. 3. [Class 83 (iii)] In a drilling-machine wherein optical means are provided for sighting a point on the work exactly in line with the spindle axis, an objective is arranged within the hollow spindle and the rays passing therethrough from the work are deflected by a reflector to an eye-piece arranged opposite to lateral openings in the spindle and its surrounding sleeve. The drill spindle 1, Fig. 1, is mounted in bearings 3, 4 in a quill 2 which is fed axially by a pinion 6 rotatable by a worm 10 hand-operated at 9, axial play of the spindle in the quill being prevented by a nut 2b. An objective 12 is secured within the spindle 1 by pins 15 and a grub-screw 16 and carries a lens 13 and a reflecting mirror or prism 14 which deflects an image of a point C on the work through apertures 19, 20 in the spindle and quill to a microscope eye-piece 17b. The eye-piece is adjustable in a sleeve 17 attached to the drillhead casing 8 and co-operates with cross wires 18 adjustable by three radial screws so as to coincide with the line of collimation of the eye-piece. Packing rings 21, 22 within the quill above and below the opening 19 prevent the spindle lubricant from reaching the optical apparatus. A mark on a flange 1f of the spindle 1 co-operating with a pointer 27 on the casing 8 indicates when the apertures 19, 20 are in line. In a modification the sleeve 17 and eye-piece are attached to the quill 2 so as to move therewith and project through a vertical slot in the drill-head 8. In a further modification the head 8 is provided with a vertical rib 32, Figs. 6 and 8, having guides 32a for a saddle 31 carrying the eye-piece 17e. The saddle is connected with the quill 2 so as to move therewith by means of a shouldered pin 33 and a screw 33b passing through a vertical slot 30a in the rib 32. The saddle may also be moved independently of or in unison with the quill by means of a rack 42 theren and gearing 39, 41 connected to a shaft 34a which may be rotated by a hand wheel 9a or a power-driven worm 36 and a disconnectable worm-wheel 37, the pin 33 then being removed. The drive may be disengaged by means of a sliding key 40 operated by a handle 43. The shaft 34a also feeds the quill 2 through bevel gearing 35.

Abstract: 644,303. Phase changing. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 29, 1946, No. 35508. Convention date, Dec. 29, 1945. [Class 38 (ii)] [Also in Groups XXI and XL (c)] A radar navigation system (see Group XL (o)) includes a calibrated phase shifting unit whereby the phase of a pulse train of recurrence frequency .93 kc/s. is accurately controlled by deriving two sinusoidal waveforms of frequency 9.3 and 93 kc/s. respectively from a 93 kc/s. waveform 38, Fig. 4, passing the three waveforms through gauged phase-shifters geared together in the ratio 100 : 10 : 1, shaping the two phase-shifted derived waveforms into corresponding pulse trains 39 and 41 and applying the waveform 38 and pulse trains 39 and 41 as inputs to a coincidence valve, Fig. 5 (not shown), which selects the half cycles of waveform 38 coincident with pulses of the trains 39 and 41 to give an output train of narrow pulses of recurrence frequency .93 kc/s. the phase of which is accurately controlled by the gauged phase shifters. The system includes a second similar arrangement for producing a second .93 kc/s. pulse train the phase of which may be accurately controlled independently of the first phase control and each of the six phase-shifters is of the goniometer type with phase quadrature inputs applied to the stators, the phase of the rotor output depending upon the angular position of the rotors 147, 149, Fig. 2 (part shown), illustrates the circuit 17 producing phase-quadrature inputs for the stators 135, 137 and 141, 143 of the 93 kc/s. phase-shifters 24 and 54. The circuit comprises a first Wheatstone bridge with the resistances 101, 103 and condensers 105, 107 in opposite arms connected in series at junction 119 to a second bridge with similar arms 109, 111 and 113, 117, the 93 kc/s. input being applied over leads 13 to the outer junctions. The other four junctions 127, 129, 131 and 133 then constitute phasequadrature voltage sources and the stators 137, 135 of phase-shifter 24 are connected in series with resistances 152 and 151 between junction 127 and junctions 129 and 131, the stators of phase shifters 54 being similarly connected between the latter two junctions and junction 133. Phase-quadrature outputs of adjustable amplitude may also be taken from tappings 182, 183 on resistances 152, 153. If the impedances of the bridge arms are made numerically equal and also equal to the reactance of the goniometer the phase shifts will be independent of temperature changes. The quadrature networks of the 9.3 and .93 kc/s. waveforms are similar but they include potentiometers connected between junctions 127 and 133 for supplying further adjustable phase outputs. Specifications 626,648 and 626,660, [both in Group XL (c)], are referred to.

Title: Photographic exposure control systems
IPC: G03B9/70
Filed: 1970-07-22
Abstract: 1313544 Photographic exposure control systems POLAROID CORP 22 July 1970 [24 July 1969] 35604/70 Heading G2A A photographic camera has a flash synchronising circuit which applies an actuation signal to a shutter and synchronously applies a firing signal to a flash lamp circuit. Schmitt trigger circuits 17, 19 are switched to de-energize electromagnets 13, 15 to initiate and terminate shutter operation as described in Specification 1313346. At the start of an exposure, switch 22 is closed. coils 13, 15 are energized, transistors 57, 63, 115 and 119 are non-conductive whilst transistors 69, 71 and 106 are conductive. Transistors 81-85 are also non-conductive. Schmitt trigger circuit is switched to de-energize coil 13 to cause the shutter to open, and also switches transistor 106 into a non-conductive state. Transistor 81 is turned on, the resulting current flowing-through transistor 81 and flash bulb 41 is applied to the gate of SCR 51 which fires and thus fires the flash bulb. During burning of the flash bulb, the voltage across resistor 35 drops, transistors 57, 63 are turned on due to the regenerative action therebetween, transistors 69, 71 are turned off and the current flow along conductor 77 is cut-off to prevent switching of transistor 92 and subsequent firing of flash bulb 42. Upon termination of the shutter action coil 15 is de-energized and a pulse of 250 Á sec duration is generated by buffer circuit 113, thus rendering transistors 115, 119 conductive for this period. The current through the shorted flashbulb is thus reduced for a period sufficient to turn off SCR 51. Contact bounce at switch 22 would normally fire more than one flash bulb. This is prevented by a buffer circuit 111 forward biasing transistor 106 to a conductive state through the energized state of Schmitt trigger 19. Subsequent actuations of contacts 22 causes flash bulbs 42-45 to be fired in sequence.
