Title: Roller mechanism for winding to and fro a web of material
Inventor: ROTTER ERHARD F
IPC: B65H18/10
Filed: 1966-01-20
Abstract: In apparatus where a web of material is wound to and fro from one stock roll on a winding roller to another stock roll on a second winding roller at a constant winding speed, the two winding rollers are coupled to the output member of one infinitely variable transmission each, the angular velocities n1 and n2 of the output members fulfilling the condition <FORM:1099563/D1-D2/1> , and the adjusting mechanisms of the transmissions being connected by an adjustable control transmission which responds to the difference in circumferential speeds of the stock rolls.  Each infinitely variable transmission is formed with an input and an output member, and an intermediate transmission member therebetween.  By means of the adjusting mechanism, the transmission member is variable simultaneously with respect to the input and output members such that the speed transmission between the input and transmission members and between the transmission and output members change in the same sense. The control transmission is in the form of a cam transmission.  In a preferred embodiment, Fig. 1 (not shown), the control transmission, a cam disc (19), is responsive to change in tension of the material via a spring urged piston (9).  The variable transmissions each comprise input and output discs (34), (36), contracting the intermediate transmission member which is in the form of a ball (37), the axis of rotation of which is pivotable by means of a slidable pin (43) contacting the cam disc (19).  A motor (26) is provided for rotating the input discs.  In an alternative embodiment, Fig. 2 (not shown), each variable transmission is in the form of cone gearing, the control transmission having the form of a grooved roller.

Abstract: 420,558. Audible-signalling apparatus. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. Jan. 26, 1934, No. 2769. Convention date, June 15, 1933. Drawings to Specification. [Class 118 (ii)] The components of the circuit for feeding an underwater or air sound emitter are so dimensioned that the frequency W feeding the oscillatory structure, which is tuned to this frequency W, the inductance L of the emitter and the capacity C of a condenser in shunt with the emitter fulfil the condition W<2>LC = 1. The inductance L and the capacity C are tuned to resonance and a further condenser tuned into resonance with the generator inductivity may be connected in series with the tuned emitter and capacity. The self inductance of the generator may be small compared with that of the emitter, the capacity of the condenser being chosen so that equal currents pass through the condenser and the emitter, the generator then supplying the purely effective current. The generator may be of like phase with the voltage or may be fed with leading current.

IPC: B23F23/12
Filed: 1918-02-20
Abstract: 114,145. Cross, M. O. March 3, 1917, [Convention date]. Gear-cutting.-In a gear tooth rounding machine, the rotating cutter 37 is given a lateral movement in a semi-circular path round the end of the tooth on the wheel 57, which is then withdrawn, indexed, and returned to position as follows, the cutter spindle being meanwhile also returned to its initial position. The gear 57 is mounted on a spindle 54, the tapered end 51 of which fits in a revoluble bush having a ratchet wheel 58 at its upper end and mounted in a supporting head 14 adjustably fixed to the table 12, moved back and returned at the right times by a cam 24, lever 26, shaft 27, levers 17, and links 16. As the table moves, it operates a lever 62, through a link 64, and causes it to engage with adjustable stops 63 on a pawl bar 61, thus causing the wheel 57 to be turned to present the next tooth for rounding. Meanwhile the cutter spindle 35, mounted in a housing 34, eccentrically adjustable in a revolving holder 32, is returned to the initial position of its semi-circular path, and afterwards given a slow working feed, by a cam 46, which revolves the holder 32 through the medium of a rack 44, and gears 43, 42, 41. The tooth to be rounded is held firmly in position by a sector carried on an arm 66 adjustably fixed to the tool support 30. A spring-pressed brake pad 53 prevents too easy movement of the bush carrying the spindle 51. The table 12 slides on a table 5, vertically adjustable through a screw 6 operated by gears 8, 9, and a shaft 10.

The back of the camera is provided with an elongated index opening 22, Fig. 1, having a scale marked at the side. The film is marked with diagonal lines 31 extending over the length of each picture, so that the portion of the line 31 visible in the opening 22 is observed to move from one end to the other as the film is wound, and the progress of the winding is continuously observed. In a modification, each picture has two diagonal lines resembling a letter V, the index opening being inclined to register with one of the lines. The number of the picture in each case is marked at the end of the diagonal lines. In another modification, the diagonal lines and their connecting- lines at the ends of the pictures are composed of rows of figures, representing the number of the picture. In the construction shown in 7, the number of the picture is indicated by .spaced longitudinal lines 41 co-operating with a scale at the side of the index opening. In another modification, the paper hacking extending beyond the ends of the film may be marked with a diagonal serrated line, so as to indicate that the film itself is not in position. In a camera having a transverse slot closed by a door, to permit the back of the film to be written upon in known manner, the door may be provided with a central panel of transparent non-actinic material and be used as the observation opening as above described. In another modification, additional index figures may be marked on the film backing to indicate the number of remaining unexposed sections. Other combinations of diagonal lines and rows of figures also may be used.

Title: Improvements in and relating to devices for automatically steering ships
IPC: G05D1/02
Filed: 1926-02-03
Abstract: 270,379. Brown, S. G. Feb. 3, 1926. Steering gear.-In gyroscopic automatic steering gear for ships, the steering motor is controlled by a two-part electrical contact device one part being operated jointly by the directional compass and the steering apparatus and the other bv an additional restraint to provide a, time lag. The joint control is effected through a differential gear. The gyro 1, Fig. 1, actuates a repeater motor 3 which drives the member 4 of a differential while the steering control motor 7 drives the other member 5, the resultant motion of the shaft 12 moving a repeater motor 14 which through gearing 15, 16 operates the controller 17. The disc of the controller 17, Fig. 2, has contact strips 21, 22 separated by an insulating strip 20, and is steadied by springs 25, 26. Freely mounted on the shaft 19 of the disc is a bracket 30 which is connected by springs 31, 32 to pins 33, 34 on the disc. Upon the bracket are arms 38, 39 adjustable relatively by the screws 46, 47 and carrying the roller contacts 42, 43. Motion of the bracket is damped by dash-pots 50, 51 the action of which is controlled by the valve 57 whereby a time lag can be introduced between the motion of the bracket and contacts relative to the disc. The contacts are suitably wired to the relay 60 of the motor 7. When the ship moves off its course, the disc 17 is rotated, a contact roller contacts with one of the contact strips and the steering motor starts up and the rudder is moved to correct the course. Rotation of the motor moves the differential and motor 14 to return the disc to normal, but owing to the time lag of the contacts-rollers, the opposite strip will be engaged and the steering motor and rudder reversed to prevent an overswing of the vessel.
