Abstract: ABSTRACT           A  beam- or truss-like reinforced concrete unit 1 to inhibit the erosion of sand beaches and river banks by the retardation and diversion of flow across them, intended to be placed on the bottom at right angles to the flow of sand-laden water, without being fastened down.  Transverse passages 5 formed by lower chord 6, upper chord 7 and diagonal members 8 allow water to flow horizontally through the unit, but cause sand to drop out.  Diagonal structural members 8 provide great stiff-ness and strength, despite the presence of passages 5.         To increase the fallout of sand, passages 5 are in two groups which meet at the centerplane of the unit, out of registry with each other, so that each group of passages is obstructed by the members 8 which form the other group.

Granted: 1993-04-13
Abstract: ABSTRACT                   LAMP HANDLE COVER SYSTEM    FOR SURGICAL LAMPS The  lamp  handle  cover  system  for  surgical  lamps includes a semi-permanent, non-disposal surgical lamp handle and its accessory component,  a sterile disposable semi-flexible handle cover, which, in combination, provides an aseptic medium by which a surgical team member can manually adjust the operating room lamp during a surgical procedure, thereby  preventing  accidental  or  unknown  incidental contamination.  The non-disposable lamp handle includes an ergonomically designed grip handle and a locking/coupling assembly which couples the grip handle to the male component of the conventional surgical lamp.  The sterile disposable handle cover is formed from a flexible sleeve closed at one end and having a relatively rigid collar formed about the opposite open end.   By holding the sleeve just below the collar, the surgical team member can easily slide the handle cover over the grip handle to engage the locking/coupling assembly which holds the handle cover in a secure position. The surgical team member can easily disengage the handle cover after the surgical procedure in a similar fashion.

Title: Current sensors
Inventor: BULLOCK DONALD F
IPC: G01R15/14
Filed: 1989-09-07
Granted: 1995-04-04
Abstract: A sensor for measuring large magnitudes of A.C. current utilizes a current divider having parallel conductors and a current comparator coupled to one of the conductors so arranged as to perform first and second stages of scaling of the A.C. current to obtain an output signal from the sensor proportional to the A.C. current.  The overall sensor ratio is the produce of the ratios of the first and second stages, thereby permitting very large ratios to be obtained. Components of the sensor are arranged so as to cause cancellation of magnetic fields by the sensor and to make the sensor immune from incident magnetic fields.

Abstract: The invention relates to a drive roller arrangement of the type in which it is possible to fold down a drive roller, freely mounted on a shaft (8), into engagement with a driven and a non-driven wheel on a vehicle. The invention makes this arrangement more compact because the roller shaft (8) mounted at the ends of the forearms (6) mounted in a elbow joint (7) on hydraulically operated (9) upper arms (5), mounted on a shaft (4) fixed to the vehicle, is caused in a retracted position to swing in towards the upper arms (5). This is done by providing a forearm (6) with a guide surface (10), which interacts with a deflector (11) placed outside the circular arc described by the elbow bearings (7) as it swings.
