Abstract: 289,286. Tattersall, H. P. July 4, 1927. Drilling-machines; drills and cutters.- In an expanding cutter for boring holes in wood &c. a. hollow spindle 2 is rotated by a belt pulley 22 and is rotatably mounted in stationary bearings 1. A toolholder 7 carrying a cutter 8 is pivotally supported on a pin 5 passing through side lugs on the spindle and has attached thereto by a pin 23 a lever 4 which is kinked at 10 and passes through a transverse hole in a pin 20 rotatably mounted '.n a sliding head 12. The head has an axial slot 11 to receive a screw 24 in the spindle and cause it to revolve therewith. A spring 19 normally maintains the head in its upper position and a rod 13 secured to the head at 14 serves for displacing it axially and causing the cutter to act on a larger diameter. A collar 15 on the rod 13 abuts a plug 16 secured to the spindle 2 to limit the upward movement of the head. In operation, for boring a hole with an undercut base, the cutter is adjusted to the diameter of the parallel portion of the hole by securing the rod 13 in the head, locking being effected by a flattened face on the rod or a slot 17 therein and a screw 18 in the plug 16. When the required depth is reached the rod 13 is displaced to oscillate the tool-holder 7 and expand the cutter and on completion of the operation the spring 19 returns the cutter to normal position to allow it to be withdrawn. By actuation of the rod 13 holes tapered in either direction may be bored and a countersink mav be combined with the cutter to act simultaneously there with.

Title: Improvements in electric remote-control apparatus combined with apparatus for transmitting indications or movements to a distance
IPC: G08C19/00
Filed: 1938-06-15
Abstract: 515,285. Electric signalling and control systems. ELLIOTT BROS. (LONDON), Ltd., and PIZZEY, C. F. June 15, 1938, No. 17771. [Class 40 (i)] In a system for transmitting indications or movements to a distance utilizing flow of D.C. in a pair of pilot wires; e.g., as described in Specification 405,043, the pilot wires are also used for further D.C. control signals and return A.C. supervisory signals. The system comprises a D.C. transmitter 1 and receiver 4 connected by pilot wires 2, 3, e.g., for transmitting reservoir water-level indications. At the receiving point of this system means are provided comprising transformer 10 fed with A.C., rectifier 12, condenser 13 and a single or mutli-way switch 5 for applying a D.C. voltage over resistance 6 to operate one or more relays 18 at the transmitting end, e.g., for setting a pump in operation. This results in the transmission of A.C. from potentiometer 26 to operate an indicator 15 at the receiving point. This signalling arrangement does not affect the contnuity of the wires of the main transmitting system. Chokes and condensers are provided to isolate the A.C. and D.C. equipment, and a contact 9 closed by switch 5 prevents control currents over resistance 6 from affecting the receiver 4 which may be connected in series with a recorder. The recorder may also be locked when such control currents are being transmitted.. Preferably, a small A.C. is normally applied to the line from potentiometer 26 so that indicator 15 is somewhat deflected and the zero position may be utilized to give warning of failure of the circuit. The D.C. control current over resistance 6 may be gradually increased by variable resistances associated with switch 5 and a number of quick-acting relays 18a - 18c, Fig. 2, may be successively controlled thereby. Each relay brings in a slow - acting power relays 22a - 22c to effect the desired operation, each of which except the first one, 22a, opens the circuit of the preceding one. Corresponding supervisory A.C. 's sent from potentiometer 26. The relays 18a-18c operate at a current higher than that delivered by the transmitter 1. The switch 5 may be controlled automatically by the receiver 4.

Title: Improvements in or relating to apparatus for detecting the presence of foreign bodies in transparent vessels
IPC: G01N33/00
Filed: 1944-09-19
Abstract: 586,939. Photo-electric apparatus for examining transparent vessels. UNITED DAIRIES, Ltd., and STOATE, N. P. Sept. 19, 1944, No. 17884. [Class 40 (iii)] Apparatus for detecting the presence of foreign bodies on the bottom of a transparent vessel by means of light directed through a scanning member and the bottom of the vessel on to a light-sensitive device which in response to a reduction in the incident illumination alters the current flow through an electromagnet controlling means for indicating the presence of a foreign body within the vessel includes means operative subsequent to the, completion of the scanning of the bottom and control of the electromagnet to increase temporarily the illumination reaching the light-sensitive device to ensure a sufficient change in the current controlled by the light-sensitive device to effect restoration of the current flow through the magnet to its original value. The apparatus is as described in Specification 586,936, the lamp 60 which is additional to the lamps 10 utilized for' the scanning operation, being located above the platforms 6 on which the bottles are carried and effectively between the contacts 43 bridged by the disc 42 attached to the arm 41 of the magnet 40 and a ramp 55 which raises the disc 42, the contacts and ramp being on a fixed ring 50 attached to a base 3. The increased illumination from the lamp 60 ensures that the current flow through the magnet 40 will retain the arm 41 in its upper position after the disc 42 has passed the ramp 55. In an alternative arrangement, Fig. 3, the rod 41 carries an additional disc 42a which in its lower position short circuits a resistance 62 normally included in the circuit of the associated lamp 10. The increased illumination re-energizes the magnet 40 and at contacts 43a removes the short circuit from resistance 62 so that the normal illumination of lamp 10 is restored. ' Specifications 586,935, 586,937 and 586,938 also are referred to.

Title: Method and apparatus for guiding a strip in motion, and more particularly a metal strip such as a strip of continuous sheet-metal
IPC: B21C47/34
Filed: 1963-05-08
Abstract: 1,031,832. Automatic control of moving strip. HEURTEY, S. A. May 8, 1963 [May 8, 1962 and Aug. 6, 1962], No.18136/63. Heading G3R Variations of the vertical position of a moving strip of material are detected by the extent to which an edge of the material obscures a photo-electric cell, and a signal so derived is caused to correct the vertical position by controlling the attitude of a roller over which the material passes, a signal derived from a further photo-electric cell obscured to an extent dependent on the attitude of the roller being applied as negative feedback. As applied to the re-winding of sheet metal strip after heat treatment Fig. 2 (not shown) the strip is passed vertically between vertical rolls 11,19, shown in plan, which are urged together by fluid-pressure actuators 27 exciting horizontal forces at the top and bottom of roll 19. Vertical movement of the strip is detected by a light source and photocell associated with one edge of the strip after passing the rolls. Variation of the output of the photo-cell, which is normally half obscured by the strip when the latter is in its desired position, controls a reversible servomotor 32 which tilts a centrally pivotted frame carrying rolls 11,19 to restore the strip to its desired vertical position by virtue of the axes of the rolls being no longer at right angles to the direction of travel of the strip. To prevent hunting, follow-up signals are provided by a further light source and photocell influenced by the position of the roll frame, the two photocells being arranged in a bridge circuit the output of which is amplified. To prevent unnecessary operation of the control system by slits and cut-outs in the strip, a relay responsive to large unbalance of the bridge may temporarily disable the control system. Two further light sources and photocell units associated with opposite edges of the strip may be mounted on oppositely threaded portions of a lead screw the drive to which is automatically controlled to maintain the spacing of units in correspondence with changes in width of the strip. The photo-cell assembly controlling the vertical position of the strip is then carried by one of these units so that the centre line of the strip rather than an edge is maintained in a desired vertical position.
