Title: Improvements in or relating to binding elements
IPC: B65B15/04
Filed: 1967-12-08
Abstract: 1,208,745. Attaching articles to strips. GENERAL BINDING CORP. 8 Dec., 1967 [6 April, 1967], No.56025/67. Heading B8C. Binding elements of the type having a back. bone with transversely projecting fingers are joined by one or more pressure-sensitive tapes extending substantially perpendicularly to the bindings. The resulting strips may either be folded in two or wound with the bindings on the outside. In the machine illustrated the bindings are guided by thin vertical bars 30, which they straddle, so that they slide on to portions 31 of the bars pivoted at 32. The portions 31 are oscillated between the two positions illustrated so that a pair of projections 33, 34 serves as an escapement mechanism to pass the bindings singly and to locate them successively in contact with a pressure-sensitive tape 21 carried on a drum 38. The drum 38 is moved in steps to feed the tape by a ratchet mechanism operated in synchronism with the movement of the bar portions 31 so that the bindings are secured to the tape at spaced intervals. A counter may cause the tape to be cut each time a predetermined number of bindings has been secured. In an alternative construction (Figs. 1 and 2, not shown) the fingers on the bindings take into the spaces between thin endless conveying belts (17) which carry the bindings beneath a roller (20) guiding the pressure-sensitive tape. The tape is moved more slowly than the conveyer belts so that the bindings are pushed into close engagement.

In the embodiment of Fig. 1 (not shown) the second cylindrical chamber is housed in the first piston rod. The level may be adjusted to give a low, intermediate or high riding height. These heights correspond to a fixed contact 140<SP>1</SP> on the cylinder 180 engaging movable contacts 144<SP>1</SP>, 1431 and 142<SP>1</SP> respectively on the piston rod 19<SP>1</SP>. To select a level, the appropriate switch (SW1, SW2 or SW3) in a vehicle level selection circuit (Fig. 2) is manually actuated. This energizes or de-energizes as the case may be one of two solenoids (SL1, SL2) controlling a valve (124, Fig. 1) which controls the supply of fluid to and exhaust of fluid from the chamber 162. When the appropriate level is reached, the relevant piston/piston rod contacts engage to energize a relay in a vehicle level detection circuit (Fig. 1), which affects the solenoids so as to cause the valve (124) to terminate the supply or exhaust of fluid.

Filed: 1967-12-15
Abstract: 1,213,638. Tracking photo-electrically. BOEING CO. Dec. 15, 1967 [Dec. 29, 1966], No.57180/67. Heading G1A. In a system for monitoring a rotating member a portion of which is expected to repeatedly traverse along a predetermined path comprises a radiation detector located on the portion and source of radiation adapted to transmit a beam narrow in the axial direction so as to intersect the path. The beam may be fixed relative to the axis of rotation or displaceable to intersect any new path that the member may subsequently adopt. The arrangement described checks that the individual blades of helicopter rotor each describe the same plane. Each blade carries a photo-diode adjacent its free end and a helium-neon laser is mounted in the fuselage so as to project a light beam into the expected path of the detectors. If one of the blade moves on to a new track the detector on that blade no longer goes through the light beam and thus no longer produces a pulse. The laser can then be angularly displaced until a pulse is again received from this detector. The angular displacement as measured by a protractor or other instrument may then be used for corrective action. A magnetic member carried by the rotor and a fixed magnetic coil pick-up provide a synchronizing pulse to identify the particular blade involved. The helicopter may have two rotors in which case the laser beam may be positioned so that the detectors of each rotor cross it or the laser may be positioned to monitor one rotor at a time.

Title: Bell hammer driving device for alarm mechanism
IPC: G04B23/10
Filed: 1966-12-22
Abstract: 1,131,760. Alarm clocks. FABRIQUE D'HORLOGERIE CHS. TISSOT ET FILS S.A. Dec.22, 1966 [Dec. 27, 1965], No.57525/66. Heading G3T. A bell ringing mechanism for an alarm clock comprises a hammer 1, a hammer drive lever 9, a spring driven gear 25 and a pinion 17, the pinion being adapted to alternately drive the lever with either of two different amounts of energy, the hammer being adapted to strike the bell at a varying rate in accordance with the varying amount of driving energy imparted to the lever. The pinion 17 engages an escape wheel 14 by Breguet toothing 23 and has toothings 34, 35, each toothing 34, 35 having the same number of teeth. The toothing 34 engages identical toothing 31 on the gear 25, whilst the toothing 35 engages identical toothing 30 on the gear 25. The toothings 30, 31 alternate around the circumference of the gear 25. On winding the spring 28, the pinion 17 rotates with respect to the escape wheel and the spring is held fully wound by the Breguet toothing, stud 24 engaging a blocking device (not shown). At the alarm time, the blocking device releases the escape wheel so that the pinion 17 is driven alternately by the toothings 31 and 30. The lever 9 is therefore oscillated between two positions and imparts an impulse to the hammer by striking the pin 8 when it is urged by the wheel 14 from a first to a second position. During its return movement the hammer strikes the lever which locked the wheel 14 during the oscillation of the hammer, so that the lever pivots again from the second to the first position thus freeing the wheel 14 which urges the lever back to the second position thus giving another impulse to the hammer. A greater driving energy is imparted to the lever when the toothing 30 drives the pinion so that the hammer strikes the bell at each end of its pivoting stroke whereas the bell is only struck at one end of the hammer stroke when the pinion is driven by the toothing 31.
