Title: Push-button selective operating mechanism
Inventor: KIDO KUNIO
IPC: G05G1/00
Filed: 1988-06-09
Abstract: A push-button selective operating mechanism which allows a push button to be either latched in a pushed in position or returned to a rest position comprises a synthentic resin member (8) having a cam groove (9) formed therein, and an engaging pin held in engagement with and movable along the cam groove (9). The cam groove (9) has lineal portions (10) and (11), a forward path portion (12) interconnecting the lineal portions (10, 11), a return path portion (13) interconnecting the lineal portions (10, 11) and a bypass portion (14) interconnecting the forward and return path portions (12, 13). The cam groove (9) is so profiled at various junctions (16-20) as to prevent return movement of the pin. When the push button is moved against the force of a return spring to cause the pin to move to a position in the forward path portion (12) just beyond the bypass portion (14), the pin will be latched in the pushed in position (15) formed in the bypass portion (14) when the push button is released. The push button is returned to the rest position when it is pushed again. If the push button is pushed in by a greater distance to cause the pin to enter the lineal portion (10), it will return to the rest position when released. <IMAGE>

Title: A balance mechanism for a machine having an oscillating member.
Inventor: PORUCZNIK PAUL
IPC: B30B15/06
Filed: 1990-05-16
Abstract: Three balance mechanisms for a press machine are described. The first balance mechanism for a press machine comprises a balance weight 91 mounted on a crankshaft 86 of the press machine, a balance weight 92 mounted on a balance mechanism shaft 93, a motor for rotating the shaft 93 and a control system for the motor. The control system ensures that the balance mechanism shaft 93 rotates in the opposite direction to, but at the same speed as, crankshaft 86. The balance weights 91 and 92 balance the primary shaking forces which arise in the press machine along the axis of movement of its ram 83. In the second balance mechanism, balance weights are mounted on two separate shafts rotated by a motor and connected by a gear mechanism. In the third balance mechanism, one balance weight is mounted on the crankshaft, another balance weight is mounted on a shaft rotated by a motor, and a further pair of balance weights are mounted on a pair of shafts rotated by a motor at twice crankshaft speed. <IMAGE>

Patent GB-2241626-A (GB)
Title: Composite images from recorded and live sources
Inventor: ITO HIROSHI
IPC: H04N9/75
Filed: 1990-09-05
Abstract: Composite images (e.g. Karaoke, in which a singer and the song words or a description may be selectively superimposed on a background scene) are provided more easily and flexibly by recording video signals (background) from multiple video sources on a disc 4 or tape; selecting one of those sources as desired; and reproducing the signal from that source along with the output of a video camera 21 (singer) and/or with graphics data (song words or description). The graphics data is recorded on the disc with the video source signals in multiplexed fashion, along with the selection signals. When the multiplexed signals are demultiplexed on playback, chroma-key composite circuitry 20 effects desired superimposition of the output of camera 21 on the source video signals and the graphics data is subsequently added at mixer 22. By combining the images in this order the graphics data is not obscured by the chroma-key process, as may happen in prior art systems where a single signal containing combined background and graphics is stored on the disc. <IMAGE>

Title: Scanning lasers for laser marking systems
Inventor: STEVENS WILLIAM HENRY
IPC: B23K26/00
Filed: 1991-02-12
Abstract: A displaceable mirror is used to cause the laser beam to scan between two extreme positions in one direction. The mirror is conveniently controlled by at least one flexure hinge driven by a piezo electric device, an electro-strictive device or a magneto-strictive device. In Fig 1 two mirrors 15 and 16 are provided, each mirror having a flexure hinge device individual thereto, and the displacements applied to the said flexure hinge devices via their respective driving devices causes the mirrors to step the path of the laser beam in one direction of scan. A computer arranged to drive the flexure hinge driving devices also controls the firing of the laser. <IMAGE>

IPC: G05B19/23
Filed: 1991-02-15
Abstract: An incremental position encoder for a closed loop position control system, includes three channels, first and second of which provide pulse signals for coarse position determination and a third to provide pulse signals for fine position determination. The pulses of the first and second channels are 90 DEG  out of phase, and the pulses of the third channel are positioned centrally within the pulses of the second channel. The second and third signals are used to determine fine position. The encoder includes an encoder wheel (32A) having a first and second series of slotted openings (46 & 47) for two of the channels, and a third series of slots (62) exactly 1/2 the width of the first and second series and positioned exactly in the center of the slots of either the first or the second series. Optical sensors (28, 29) sense the presence of the openings at respective reference points and provide the three signals described above. <IMAGE>

Abstract: A plastics container, for paint or the like, is provided with a reinforcing element 2 around the opening of the container body 1 and with a pivotal handle. In order to avoid the weight of the container being borne by only the join 4 between the reinforcing element and the container body when the container is held by the handle, the container body is also provided with support elements 9, which may be integrally formed with the container or fixed thereto, that engage with the handle and bear at least a part of the load. The elements 9 are connected to the handle by fastening elements eg rivets 10 which may be formed integrally with the element or separately (fig 4). The elements 9 when formed integrally with the container extend horizontally and are folded through 90 DEG  over the handle ends. The reinforcing element 2 is provided at diametrically opposed locations with indented portions 5 which receive inwardly protruding lugs 6 formed at the opposite ends of the handle (7, fig 3) so that the handle is pivotally mounted to the reinforcing element. A recess is provided in the reinforcing element which allows the handle to lie flush with container body when not in use (fig 3). <IMAGE>

Title: Label applicator having automatic height positioning
Inventor: SZEWCZYK RICHARD S
IPC: B65C9/26
Filed: 1992-04-06
Abstract: A top ply labeller (70) includes a presser foot (118) and applicator pad (120) arranged for relative movement to one another which travel along a rectilinear path as the ram (132) of an applicator cylinder (96) is extended and retracted toward and away from the top surface of a lay-up of sheet material whereby a label (81) carrying identification information (cut from strip 80) is applied at predetermined positions. The applicator backplate (72) is mounted for relative vertical movement (along guide rods 74) toward and away from the top ply surface to maintain the labeller (70) at a desired elevation above the top ply. Sensors (124, 126) detect when the pressure foot (118) contacts the surface of a top ply and when continued movement of the applicator pad (120) relative to the pressure foot (118) applies the label. The height of the labeller (70) is adjusted when the ram (132) of the applicator cylinder (96) is fully extended without the pressure foot (118) making contact with the surface of the top ply. <IMAGE>
