Abstract: An automatic on-off sprinkler head (11) includes a housing (12) that defines a primary chamber (61), a pilot chamber (60), an inlet orifice (19), and outlet orifice (16), a fill port (37) providing limited flow between the inlet orifice (19) and the pilot chamber (60) and a release port (54) for discharging fluid from the pilot chamber (60). Supported by the housing (12) between the inlet (19) and outlet (16) orifices is a flexible diaphragm (28) with wall portions that open a flow path between the orifices when in an open position and close the flow path when in a closed position. The diaphragm (28) has first surface portions exposed to the primary chamber (61) and surface portions opposite the first portions and expand to the pilot chamber (60). In response to a predetermined difference in pressure between the pilot (60) and primary chambers (61), the wall portions are moved to the open position and are retained in closed positions by less than the predetermined difference in pressure. A pilot valve (52) controls fluid flow through the release port (54) and in response to a fire condition, a sensor (53) moves the normally closed pilot valve (52) into an open position and thereby produces a differential pressure across the wall portion that opens the diaphragm (28) main valve. The use of a flexible diaphragm (28) as a valve closure eliminates any requirement for movable seals and thereby provides a valve that is highly resistant to leakage when in a closed condition and sensitively responds to fire conditions by establishing fluid discharge between inlet (19) and outlet (16) orifices.

Abstract: A device for mounting printed circuits (15) with plate-like electronic components (33) is proposed, in which the components (33) are stacked in a bundle of tubular magazines (32) which has the same grid as the layout of the printed circuit board (15). The components (33) appear from the magazines (32) in the windows (66) of a sliding plate (20), which slides the components (33) under a bundle of suction tubes (50). These suction tubes (50) pick up the components (33) and place them on the printed circuit board (15) by an axial movement. The sliding plate (20) is preferably arranged underneath the magazine (32) so that the components (33) enter the windows (66) of the sliding plate (20) under the influence of gravity. This results in a simple drive, with a small number of drive members and movement operations. A diaphragm plate (22), which is movable relative to the sliding plate (20), can advantageously be provided for covering the windows (66) during transverse transportation to the suction tubes (50).

Abstract: Herein disclosed is a label peeling device for use with a label issuing machine such as a hand labeler or a measuring printer. The label peeling device comprises a fed unit for feeding a label web (1) which has a plurality of labels temporarily adhered in series to web-shaped backing paper (2). Further comprised is a peeling unit for turning exclusively the backing paper of the label web, which is fed by the feed unit, so that the labels may be peeled one by one from their backing paper by their own rigidity. An auxiliary peeling member (33) is arranged in the vicinity of the peeling unit. This auxiliary peeling member has a label abutment portion (33a) so shaped and sized that even the label, which might otherwise fail to be peeled off merely by the turn of the backing paper (2) at that particular vicinity, is brought into abutment against the label abutment portion until is is forcibly peeled from the backing paper. In a preferred embodiment the auxiliary peeling member is made rotatable in the advancing direction of the labels.

Abstract: A method and system for recognizing complex patterns, such as Chinese characters (or Kanji), identifies patterns by stroke recognition using detailed information about stroke shape and specifically curvature characteristics. Written strokes are categorized into different specific stroke types and are assigned stroke identity labels by comparison of distance metrics generated with reference to stroke templates, each template comprising information specifying position of a point and permissible deviation for each such point along a stroke. Deviation values may differ from point to point and from stroke type to stroke type. The data on the written stroke may be rotated or displaced relative to each stroke template to enhance the likelihood of stroke recognition. Limited information about stroke position relative to other strokes may be preserved and employed to resolve ambiguities among accumulations of stroke identity labels found to ambiguously indicate more than one pattern or character.

Abstract: An energy recovery system (100) for manipulator apparatus is provided that supplies energy to drive the manipulator apparatus from a pressurized source (at 12) and that recovers energy from the manipulator apparatus during the deceleration phase of the manipulator arm in one or more of the controlled axes. The energy recovery system (100) includes a variable displacement pump/motor (10, 26) that is driven by a motor/generator unit (34). The hydraulic pump motor unit includes a pressure responsive control arrangement (40) for selectively controlling the hydraulic pump motor between a motor mode and a pump mode. The pump/motor in the pump mode is driven by the motor generator unit to supply a source of pressurized fluid to the servo valves that control movement of the manipulator arms through hydraulic actuators. When the manipulator arm is decelerating, the servo valves for the axes are closed and the decelerating hydraulic actuators provide a source of pressurized fluid at a pressure above the normal pressurized supply from the pump. The pressure responsive control arrangement of the pump/motor senses the high pressure condition and switches the pump/motor to the hydraulic motor mode. In the hydraulic motor mode, the pump/motor in response to a source of pressurized fluid from the hydraulic actuators operates the motor/generator in the generator mode to supply electrical energy. The motor/generator unit in one arrangement includes a high mass flywheel to supply energy storage for the manipulator apparatus.

Abstract: An auto chroma filter averages the value of successive color burst amplitudes on a line-by-line basis over many video frames, by fetching a burst value from memory (28) and loading it into an up/down counter (18), and also into a D/A converter which provides the chroma filter output signal. A comparator (10) compares an incoming new burst value with the output signal, whereby the counter increments or decrements the value toward the incoming new burst value in response to the comparator. The updated value then is loaded back into memory in the same location from which it was fetched, and the cycle continues for each video line and successive frames.
