Title: Tape slack detector of tape recorder
Inventor: RI CHIYOUKOU
IPC: G11B15/665
Filed: 1996-01-04
Abstract: PROBLEM TO BE SOLVED: To prevent damage to a drive system, by providing a light-emitting element and a light-receiving element at the final position of a tape after loading, and instantaneously stopping driving of a deck mechanism when any sag of the tape is detected. SOLUTION: In the case where tape sag is generated, since a tape 15 is located between a light-emitting element 30 and a light-receiving element 31, a light emitted from the light-emitting element 30 is interrupted by the tape 15 and thus the light-receiving element 31 is prevented from receiving the light. When the light-receiving element 31 does not receive the light even though a tape loading mechanism is actuated, a microcomputer 50 as a halting device recognizes an abnormal operating state based on a signal from the light- receiving element 31 and sends a stop signal to a deck drive unit to prohibit a cassette unloading mechanism from proceeding, thereby automatically stopping driving of the mechanism.

Title: Process and apparatus for gas-phase polymerization of alpha olefins
IPC: C08F2/00
Filed: 1996-07-18
Granted: 2000-10-31
Abstract: Process for gas-phase polymerization carried out in two interconnected polymerization zones, to which one or more alpha-olefins CH2=CHR are fed in the presence of catalyst under reaction conditions and from which the polymer product is discharged. The process is characterized in that the growing polymer flows through a first polymerization zone under fast fluidization conditions, leaves said first zone and enters a second polymerization zone through which it flows in a densified form under the action of gravity, leaves said second zone and is reintroduced into the first polymerization zone, thus establishing a circulation of polymer around the two polymerization zones. The novel process allows olefins to be polymerized in the gas phase with high productivity per unit volume of the reactor without incurring the problems of the fluidized-bed technologies of the known state of the art.

Title: Improvements in or relating to apparatus for feeding cut tobacco
IPC: A24C5/39
Filed: 1937-01-08
Abstract: 488,617. Tobacco-feeding mechanism. RUAU, F. F., and MOLINS MACHINE CO., Ltd. Jan. 8, 1937, No. 599. [Class 130] In a cigarette-making or a tobacco-packaging machine, a transfer conveyer moves along the length of a shower of tobacco and feeds it to a distributing means which spreads the tobacco across the surface of a wide conveyer. As shown in Fig. 1, a pivoted flap 12 feeds tobacco from a reserve supply 11 into a hopper 10 from which it is removed by a carded drum 14 and showered by a picker 19 on to a transfer conveyer which moves along the length of the shower. A small mass of tobacco is maintained in the angle between the drum 14 and a brushing roller 15 and is kept in a loose condition by a rake 16 and is periodically pressed on to the drum 14 by a tamper 17. The transfer conveyer may be formed by a single belt or by a pair of belts 20 running at high speeds in opposite directions and discharging the tobacco at a point midway along the length of the shower into a tapering guide 22 having a pin-studded roller 24 at its lower end to deliver the tobacco on to a wide conveyer 21. The guide and roller may be rotated about a vertical axis or as shown in Fig. 4 the guide may be mounted on a support 35 and oscillated, transversely to the direction of movement of the conveyer 21, by a flexible connection 36 adjustably connected to a bell-crank lever 37 operated by a cam 39. The roller 24 is driven bv a flexible belt 25 passing over guide pulleys 27 supported by a spring-pressed lever 29. In Fig. 9, the roller 24 is omitted and the tobacco is delivered by the belt 20 through a fixed member 46 into a guide 22, supported by a carrier 41, which is rotated by gearing 44, 45. The outlet end of the guide 22 is inclined and may be moved in a circular path above the conveyer 21 or may be moved through an elliptical path whose major axis lies in the direction of movement of the conveyer 21. by pivoting the guide at 47 to the carrier and providing the guide with a roller 48 which co-operates with a stationary cam 49. In modifications the conveyer belt is replaced by a vaned roller which is oscillated along its axis of rotation while it delivers tobacco on to a further conveyer, or by a smooth drum on which the tobacco is compacted as described in Specification 441,402. Specification 488,029 also is referred to.

Title: Feed mechanism for presses
Inventor: HARDING BRIAN
IPC: F16H1/16
Filed: 1959-01-07
Abstract: 891,535. Feeding strip stock. T. I. (GROUP SERVICES) Ltd. March 22, 1960 [Jan. 7, 1959], No. 605/59. Class 83 (4). Means for feeding to a press 12 strip 13 preformed with equi-spaced holes comprises stripguides 10, 11, a rod 14 carrying an arm 16, 17 on each side of the press-dies, the arms each having a nose 16a, 17a for engaging the stripholes, means 15, 22 for reciprocating the bar a distance equal to the space between adjacent holes and for turning the bar to engage and disengage a nose 16a, 17a with a strip-hole at the ends of opposite strokes of the bar, and a pair of plungers 23, 24 below the guides 10, 11 at opposite sides of the press for vertical movement to engage the strip-holes when the noses 16a, 17a are disengaged therefrom. As applied to a press for dishing or blank-punching chain-wheels (not shown), a conveyer feeds the strip between the adjustable guides 10 to operate a switch 27 which controls the supply of compressed-air to cylinders 25, 26 for raising the plungers 23, 24. As these approach the top of their stroke, they operate switches 35 on the plungers which control the supply of compressed-air to the cylinder 22 for turning the arms 16, 17 to their inoperative position and to a cylinder 29 for pivoting to an inoperative position a bracket 28 supporting switch 27. At the end of its stroke, cylinder 22 operates a switch (not shown) which controls the supply of compressed-air to the cylinder 15 for retracting rod 14. A switch 36 ends the retraction and operates cylinder 22 for returning the arm 16 to the strip and cylinders 25, 26 for lowering the plungers 23, 24. When the nose 16a engages a strip-hole, a piston in cylinder 22 operates a switch for supplying compressed-air to cylinder 15 and feeding the strip. The feed-stroke is ended by contact between arm 16 and a switch 37 which causes plungers 23, 24 to engage the strip and again operates switches 35. When the strip reaches a switch 34 between the press-dies, lowering of arms 16, 17 is controlled by switches (not shown) operable by the press, so that they are not lowered until the upper die has been retracted. When the strip has progressed enough to be engaged by the arm 17, the trailing end of the strip will move from beneath an arm 33, connected by a pivot 32 and a spring-loaded arm 31 to a switch 30, so as to operate the switch, which causes bracket 28 to be lowered ready for the next strip. Operations are halted until the next strip raises the bracket. Manually-operable switch means may control the discharge of the last strip. Lips P on the guides prevent the strip rising with the upper die. The plungers 23, 24 and arms 16, 17 are adjustable axially of the feed-path.

Title: Improvements in or relating to electrical pulse generator circuits
IPC: H03K4/90
Filed: 1966-01-07
Abstract: 1,070,878. Semi-conductor circuits. TEKTRONIX Inc. Jan. 7, 1966 [Jan. 19, 1965], No. 893/66. Heading H3T. In a pulse delaying circuit, particularly for use in a sampling oscilloscope, a ramp waveform 60 is generated by charging a capacitor 36 which is normally clamped by a gating transistor 18 having an anti-saturation circuit. Trigger pulses are derived at 48 from the Y deflection waveform at 46 and are differentiated at 50 before being used to trigger two tunnel diode bi-stable circuits 54, 26. The output from tunnel diode 26 turns off gating transistor 18 and allows capacitor 36 to charge via a constant current transistor 10 so as to provide a ramp waveform 60. When the ramp voltage 60 exceeds that of a staircase waveform from 64, comparator diode 62 becomes conductive, triggering a further bi-stable tunnel diode 68 the output from which is differentiated at 72 to provide a pulse at 82 which may trigger an avalanche transistor sampling circuit. The constant current via transistor 10 is arranged to " arm " the tunnel diode 68 so as to improve its triggering stability. The response of the gating transistor 18 is improved by an anti-saturation circuit 40, 28. The circuit is reset after a time, adjustable by switches 38, 86, by a monostable multivibrator 84. The comparison of waveforms 60 and 64 enables different portions of the vertical input signal waveform to be sampled at successive times. The sampled signals are stored and displayed as a lower frequency waveform on a cathode-ray oscilloscope.
