Title: Holographic backgrounds
Inventor: BLYTH JEFFREY
IPC: G03H1/04
Filed: 1984-09-12
Abstract: A method of holographing an object wherein, in order to obtain a required diffusely illuminated back-ground, the object is holographed against a background constituted by a hologram which is adapted to simulate a real background from which the hologram has been produced. Typically, the object is holographed against a hologram of a matt white box. The background hologram is preferably a hologram used in its pseudoscopic mode but may be a hologram used in its orthoscopic mode but projected as a real image.

Title: Process for controlling the microbial environment in abalone mariculture
Inventor: LOCKWOOD GEORGE SHELLINGTON
IPC: A01K61/00
Filed: 1985-08-05
Abstract: In a process for mariculture of abalone, the male and female abalone are pretreated prior to spawning with one or more antibiotics in a seawater bath that is essentially bacteria-free. Eggs are filtered from the bath in which spawned and fertilized, and placed in a hatching bath of essentially bacteria-free seawater containing one or more antibiotics. After the eggs hatch, and the larvae have broken away from their respective cases, the larvae are transferred, free of egg debris, to a third bath of essentially bacteria-free seawater containing one or more antibiotics and selected beneficial antibiotic-resistant strains of bacteria which are separately cultured and which control ammonia and provide other benefits. Upon development to a settlement stage, the larvae are transferred to a final settlement bath of essentially bacteria-free seawater containing one or more antibiotics and selected beneficial antibiotic-resistant strains of bacteria which induce settlement, are a source of food for the duration of larval development and subsequent early growth of the abalone, and help control the level of toxic ammonia to within acceptable levels.

Title: Vehicle gear assembly for torque transfer to two or four-wheels
Inventor: DICK WESLEY M
IPC: F16H37/06
Filed: 1986-02-20
Abstract: A gear assembly for selectively shifting the driving torque in an engine driven vehicle to either a 2 or 4-wheel high mode while in motion, or from a neutral position to a 4-wheel low mode and return, has five main gears including an input set of two (40,45) and an output set of three constant mesh gears (50,55,57) rotatably mounted in fixed positions and a synchronizer (25) in between the two sets in selective driving association with the output gear set. Selective transfer of torque from the input drive to the assembly to either or both the front and rear output shafts is effected by operation of a single shift rod (80, Fig. 4, not shown) which in turn moves a single fork (90) both for activation of the synchronizer and for shifting the assembly into its 2 and 4-wheel high, neutral and 4-wheel low drive positions through interconnecting gear clutch collars. A poppet member arrangement in the form of a poppet ball or slug provides an interlocking connection between clutch collars (60, 65) for their positive positioning in the drive positions manually selected by way of the shift rod. <IMAGE>

Title: Bifilar pendulum vibration damper for automotive installation
Inventor: BERGER ALVIN HENRY
IPC: F16F15/14
Filed: 1987-01-21
Abstract: A bifilar type pendulum automotive engine vibrational damper has at least one pendulum (48) with an inner curved cam follower surface (68) that is alternately engaged and disengaged from a pin type cam (70) fixed on the pendulum carrier (40) during low engine crankshaft operating speeds, such as during engine start-up or shut-down, to force the pendulum (46,48) to follow a path close to the path defined by the swinging arcuate movement of the pendulum (48) during operation at normal engine crankshaft operating speeds. A minimal radial clearance is provided between the pendulum's curved surface (68) and pin (70) during the normal crankshaft operating speeds to reduce the impact of metal to metal contact between the pendulum (48) and rollers (50) or carrier (40) as the pendulum (48) alternately falls inwardly against the carrier (40) in response to gravity and then is forced outwardly due to centrifugal force. <IMAGE>

The rod has full diameter portions (19a-19d) greater than the internal diameter of each tubular portion, and reduced diameter portions (20a-20e) substantially the same as the internal diameters of the tubular portions. Initially the full diameter portions lie in/along the connecting portions, and the reduced diameter portions lie in the tubular portions. In use the wall tie is received in a hole in a cavity wall and the rod driven along the expandable member to expand tubular portions into tight engagement with the material of the cavity wall to secure the wall tie in place. A method of producing the wall tie is also disclosed. <IMAGE>
