Title: Rotatable suction head for article-handling apparatus
Inventor: WOERNER KLAUS D
IPC: B25J15/06
Filed: 1990-01-12
Abstract: A rotatable suction head for an article-handling apparatus has a suction surface 29 which may be rotated to assume the same orientation as the top surface of an article that it is adapted to contact. Once the head rotates to assume the same orientation as the top surface of an article at a pick-up position and is locked in that orientation, the article may be moved to a work station. The orientation of the bottom surface of the article at the work station is then known for facilitating an operation on the article. The suction head includes a suction surface Portion 29 fitted to a spherical member 120 rotatable in a spherical seating formed by the end of a finger 100 and enveloping cylinder 106. The spherical member has an internal channel for providing suction via 102, 103, 104, when the article is held on suction surface 29, the spherical member is locked in place by relative longitudinal movement of finger 100 and sleeve 106 caused by pneumatic piston 110 acting on finger 100. <IMAGE>

Title: Electron gun to provide electrons grouped in short pulses
Inventor: AUCOUTURIER JEANNE
IPC: H05H7/02
Filed: 1991-06-13
Abstract: An electron gun comprises a cathode (K), a grid (G), and an anode (A) between which the applied voltages are radio- frequency voltages. The cathode (K) is disposed on the central conductor (1) of a coaxial cavity (2), facing the grid (G) terminating the cavity (1). The cavity (1) is terminated at the other end by a short-circuit (3) and includes a coaxial branch line (4) so as to resonate at two frequencies F1 and F2 multiple of f0, whose beating induces a radio-frequency grid-cathode voltage. The grid (G) terminates another coaxial cavity (10) whose central conductor (11) is hollow and whose end facing the grid (G) forms the anode (A). The other coaxial cavity resonator is excited and resonates at a frequency F0 multiple of f0, which induces a radio-frequency anode-grid voltage. A proper selection of the frequencies, F0, F1, F2 allows to obtain electrons bunches of very short duration. <IMAGE>

Title: Gutter bracket; gutter seal
Inventor: STANIFORTH GRAEME
IPC: E04D13/068
Filed: 1991-08-07
Abstract: An adjustable rainwater gutter bracket consists of a bracket arm 1 with horizontal teeth 17 at its rear, a mounting block 3 with horizontal teeth 37 at its front, and a locking slide 5 housed in the mounting block. Lugs 21 on the bracket arm can enter a channel in the mounting block to retain the bracket arm loosely while allowing the teeth to be inter-engaged at different relative heights. The locking slide can lock a hook 57 provided on the bracket arm, to hold the bracket arm against the mounting block with the teeth firmly inter-engaged. This enables the height of the gutter to be easily adjusted. The mounting block is installed first, the bracket arm is fitted to it subsequently. A gutter seal strip 69 may have an integral resilient pad 91 at its end, to be trapped between the gutter edge and a rigid retaining clip 77 of a gutter fitting, to retain the gutter reliably without requiring accurate moulding of the gutter fitting. The seal strip may have a non-uniform external cross-section with a rib 75 engageable in a recess provided in the fitting, to retain the seal strip without requiring an end lip on the fitting. The seal strip may incorporate stiffer edge regions. <IMAGE>

Title: Suspended hanging basket hydration indicator
Inventor: WILLIAMS JOHN TANAT
IPC: G01G19/14
Filed: 1992-07-09
Abstract: A hanging basket is suspended by way of a spring balance. The state of hydration of the hanging basket is directly proportional to its weight. The maximum weight of the fully watered basket will extend the device to the moveable marker G indicating such. As the water is utilized so the basket will lighten and the indicator moved towards the marker F previously placed at the point of a dry basket. Inspection of the position of the marker indicating the weight and its relative position to the moveable markers will indicate the need for the amount of watering that that basket requires at that time. <IMAGE>

Title: Modifying duty of print head to prevent overheating.
Inventor: KATO YUKIHISA
IPC: B41J2/30
Filed: 1993-09-29
Abstract: In a dot matrix printer of the kind in which the printing mode is changed to a mode of lower duty when the sensed temperature of the head exceeds a predetermined temperature, printhead duty is a criterion governing the change. Over-protection (consequent upon using a temperature criterion alone) is thereby avoided. As described, a plurality of predetermined temperatures are employed with respective different printing duties such that:   (a)Bidirectional high density to bidirectional two-split high density is caused by exceeding a first (low) temperature (T1) while high duty printing is being performed Bidirectional to unidirectional is caused by exceeding a second (higher) temperature (T2) while a duty lower than bidirectional high density is being performed. In this case bidirectional two-split high density changes to unidirectional two-split high density, and bidirectional low density changes to unidirectional low density. (c) Unidirectional to no-printing is caused by exceeding a third (even higher) temperature (T3).   <IMAGE>

Title: Time domain adaptive control system for active noise cancellation
Inventor: STOTHERS IAN
IPC: G05B13/02
Filed: 1994-03-25
Abstract: An adaptive response filter W has a plurality of time domain filter coefficients which are operative to filter the input signal to provide a control signal for the plant C so that the plant generates the required output signal. A model filter C which also has a plurality of time domain filter coefficients models the response of the plant and filters the output signal using the filter coefficients in relative time reverse order to provide at least one filtered output signal. A delay Z delays the input signal for a predetermined time period. The adaptive response filter receives the delayed input signal and collates this with a respective filtered output signal and adjusts its filter coefficients using the outcome of the collation to adjust the control signal for the plant such that the output signal of the plant converges towards a required level. <IMAGE>

Title: Receiver arrangement for receiving a current pulse
Inventor: MAPLESTON DAVID BERNARD
IPC: H04B10/10
Filed: 1994-04-29
Abstract: An infrared remote-control receiver employs at its front end a gyrator-configured transistor (12) operating as a current-to-voltage converter, but derives its data information from a negative-going gyrator output pulse in preference to the more conventionally used positive-going pulse. This negative-going pulse may be wider than the positive-going pulse and reduces the bandwidth demand on subsequent processing circuitry. This enables low-bandwidth, low-current hardware to be used which makes the receiver ideal for use in battery-operated systems. Also, the negative-going pulse is easier to detect, as it directly follows a disturbance known to be in the opposite direction. The result is an increased receiver sensitivity. <IMAGE>
