Title: Colour signal separating apparatus
Inventor: HAYASHI MASAHIKO
IPC: G01J3/46
Filed: 1984-10-08
Abstract: Luminance signals (Y) and two colour signals (R, B) from a TV colour camera viewing objects. particularly fruit to be harvested, are processed by multiplying (2) the luminance signal (Y) by adjustable (R1, R1') lower and upper limit coefficients (K1, K1') for red and similar coefficients (K2, K2') for blue. Where both red and blue signal intensities fall between their respective limits (K1 Y, K1' Y, K2 Y, K2' Y), comparators (3, 3') and AND gate (4) insert a logical 1 in a frame memory. Before multiplication and comparison, the signals are preferably converted to DC relative to an absolute dark level. A strobe light, synchronized to the camera, may illuminate the objects. The aperture of the camera may also be adjustable automatically to stabilize the light level. The pixels with logic 1 may be indicated on a monitor display (5). <IMAGE>

Title: Method of recharging a sealed lead-acid storage battery
Inventor: HIRONAKA KENSUKE
IPC: G03F1/00
Filed: 1987-01-27
Abstract: In the method, a sealed lead-acid battery which has been charged by causing a current to flow thereinto in a charging direction is subjected to a first step in which current is caused to flow into the battery in a direction opposite to the previous charging direction, followed by a second step in which the battery is recharged with constant-voltage, constant-current or semi-constant voltage by causing a current to flow into the battery in the previous charging direction. The method improves recovery of battery capacity of batteries which have remained in an overdischarged state for extended periods and then charged conventionally prior to the application of the present method. The first step may be effected by applying -2.45V to the battery for one minute, +2.45V being applied in the second step.

Inventor: BROWN GEORGE CYRIL
IPC: E02D33/00
Filed: 1987-05-23
Abstract: A method of and apparatus for testing the safe-loading characteristics of an existing concrete floor slab (12) by drilling out or otherwise isolating a core (13) so that it is capable of free vertical movement relative to the remainder of the slab. The core (13) is drilled carefully so that the sub-base below the slab remains undisturbed, drilling being terminated as soon as the core starts to spin. A test rig consists of a framework (14) with platforms (15) to receive ballast. An upstanding frame (16) with cross beam (17) locates a hydraulic jack (18) which acts via probe (20) on the isolated concrete core. Upon extension of the jack, compaction of the sub-base immediately beneath the core is measured by a plate (19) reading off against a graduated scale (22). Alternatively transducers may measure force applied and compaction. The measurement of compaction is correlated with known properties of the concrete slab to determine the safe-loading characteristics of the floor in the test zone. The core may be removed and replaced by a steel probe for the compaction test. <IMAGE>

Patent GB-2198595-A (GB)
Title: Circuit card connectors
Inventor: DAVIES KEITH
IPC: H01R12/89
Filed: 1987-11-23
Abstract: A zero insertion force connector for a circuit card, especially a 'smart' or 'soft' card, includes a main body member supporting contacts for engaging with those on the card. A carrier member engages the card and carries it into engagement with the connector body by sliding in a predetermined mating direction in the plane of the card. Limited relative movement in the mating direction is allowed between the card and the carrier member, and a spring or other resilient means urges the card towards the limit of its movement in the mating direction. When the card has been advanced sufficiently to align the mating contacts, an abutment is engaged to prevent it moving further and the carrier then engages ramps which compel it to move tranversely and urge the card in a direction perpendicular to its own plane to make contact and apply adequate contact pressure. The carrier is then releasably latched in position in the body.
