Title: Orthodontic expander apparatus
IPC: A61C7/10
Filed: 1972-09-22
Abstract: 1389885 Orthodontic devices G OUAKNINE 22 Sept 1972 [5 Oct 1971] 43945/72 Heading A5R An orthodontic expander apparatus for transverse enlargement of the palate comprises two members 1 and 2 each intended to be embedded in a block of resin (14 and 15) Fig. 3 (not shown) conforming to the shape of the palate, an endless screw drive (7) Fig. 2 (not shown) mounted in one member 2 engaging in a rack 5 fixed in the other member 3 so that on rotation of the screw the rack 5 is slidable in the member 2. The members 1 and 2 have holes along their edges parallel to the rack axis enabling resin reinforcing wires (19) Fig. 3 (not shown) to be attached thereto. A detachable cap 11 on member 2 protects an adjustment head 9 on screw drive (7). Tapped holes 4 in the outer faces of the members allow the attachment to one member of two threaded rods (22) and (23) Fig. 4 (not shown) which with palate (24) and ring (26) allow traction to be applied to a single tooth (25) the traction force being reacted by a moulded resin block around the other piece. The moulded resin blocks may be fixed to the palate by loops (16) extending from the block to a tooth. A cutting wire (28) Fig. 5 (not shown) is used to separate the resin into two blocks while still plastic the members being embedded in each block. Guide rods (17) Fig. 3 (not shown) can be used to increase the stiffness of the connection between the pieces. The rack 5 may be of semi-circular cross-section running in a semi-circular slot and it also may be curved in the longitudinal sense running in a similarly curved slot.

Abstract: 1,193,648. Feeding sheets. W. E. JOHNSON. 29 Sept., 1967 [3 Oct., 1966], No. 44035/66. Heading B8R. A casing 10 includes a tray 18 for a stack of sheets 11 which are fed successively from the top by a friction roller 13 rotated through a non-elastic, e.g. chain coupling 16 by a hand wheel 17, the roller 13 resting on the stack by gravity and its shaft 14 being coupled to the shaft 15 of the hand wheel by an arm 20 having housing members 21 at each end to support the shafts, whereby the drive force tends to raise the roller by pivoting the shaft 14 about the shaft 15, which rotates in the casing, producing a slight jumping action. The sheets are inverted round the roller and move past a window 12 and into a tray 18a past a deflector plate 19. The sheets may be provided with programmed information on their lower sides in the stack, and the device may be used as a teaching-machine.

Title: Improvement in discontinuous controllers
IPC: B65H23/032
Filed: 1962-11-21
Abstract: 979,620. Automatic web position control. RHONE-POULENC S.A. Nov. 21, 1962 [Nov. 22, 1961], No. 44085/62. Heading G3R. In an intermittently operated controller for automatically correcting deviations of a variable from a desired value, each time the variable is restored to the desired value there follows a reverse adjustment of the controller which is a predetermined fraction of the forward adjustment, a signal corresponding to which has been stored. As applied to an on-off control system for maintaining a variable at a desired value, deviations detected at D, Fig. 2, operate a relay R. With switch Cr normally in a position opposite to that shown, a generator 1A then produces pulses which cause periodic operation of a regulator OR to correct the variable. A computer M, including a store such as a step-by-step switch, records the total number of correcting pulses supplied up to the time that the detector indicates that the variable has returned to the desired value. Computer M then changes over switch Cr to the position shown to cause a generator 1D, having a greater pulse repetition frequency than generator 1A, to operate regulator OR in the reverse direction until it is adjusted by an amount which is a predetermined fraction of the previous forward adjustment. Application to a two-way and off system controlling the lateral position of film in a film-casting machine in response to the outputs of photo-cells associated with each edge, is described.

A printing machine suitable for printing on box blanks comprises a printing cylinder 1, a fountain roller 8, a longitudinally reciprocating roller 2, a messenger roller 9, means for rotating the fountain roller 8 at a constant speed, and means for operating the machine automatically with a time cycle corresponding to a determined rotation of the cylinder 1, the roller 9 being placed in contact with the roller 8 during said cycle for an adjustable time and then being placed in contact with the roller 2 for the rest of the cycle. The inking train also includes forme inking rollers 5 and 6, a second longitudinally reciprocating roller 4, and a transfer roller 3. The roller 9 rotates in a movable support 10 which is articulated at 11 and operated by a pneumatic piston and cylinder device 12. After each revolution of the cylinder 1 a device 13 sends an electric pulse through a line 14 to a counter 15 which after a determined number of pulses sends a signal to the device 12 causing the roller 9 to contact the roller 8 and energizes a timing device 16. After a given time the device 16 sends another signal to the device 12 to bring the roller 9 into contact with the roller 2. The device 16 may operate by counting constant frequency pulses in a line 17. The roller 8 may be rotated at a constant speed by an independent motor, not shown, and the speed of its rotation may be adjusted while the machine is not being operated. The electric control system may be replaced by the mechanical, pneumatic, or hydraulic equivalent.
