Title: Body Motion Compensation Filter
IPC: G01V1/38
Filed: 1979-08-15
Abstract: A filter for use in determining the vertical displacement of a body in water and more particularly for surveying underwater terrain from a towed sensor comprises a first portion receiving, 52, a position signal from a pressure transducer and having a transfer function which is substantially the product of a predetermined constant and a first real rational polynomial function P1(s)/Q(s); and a second portion receiving at 54, a vertical acceleration signal from an accelerometer and having a transfer function which is substantially the product of a predetermined constant and a second real rational polynomial function SP2(s)/Q(s). The output signals from the two portions are summed at 70. The degree of Q(s) is an integer n greater than 2, and that of P1(s) and of P2(s) is less than n. The magnitude of P1(s)/Q(s) is to be less than 1 for s=jw where w is any radial frequency within the pressure transducer noise spectrum. While the zeroes of Q(s) are such that 1/Q(s) has a 20n db/decade roll-off in the said spectrum P1(s) and P2(s) are constrained to satisfy the relationship P1(s)+s<3>P2(s)=Q(s). <IMAGE>

Title: Banknote dispensing machine
IPC: G07D11/00
Filed: 1980-04-11
Abstract: The invention relates to a machine in which banknotes are fed as a stack to an outlet closable by a shutter arranged to nip the stack at the outlet, further feed of stacks to that outlet being inhibited until such nipping has ceased A motor drives a train of rollers to deliver banknotes from plural cassettes along a flowpath to a pair of conventional tined spiral stacking wheels 42, 43. The notes are stripped from the wheels to fall in a stack 45 on a delivery belt 250 in the delivery station. The delivery station 8 includes two outlets and two shutters 39. A reversible electric motor 10 drives through belts 13, 18, the belt 250, on which the stack of notes 45 is to drop, and drives a cam 25 through a one- way clutch 26. Through belts 13, 19, the motor drives a similar cam 30 through a one- way clutch 29. Cams 25, 30 co-operate with cam followers e.g. 36 attached to rods e.g. 37 to lift a respective shutter 39 arranged to nip a stack of banknotes on to a platform 40. A sensor 41 indicates the presence of the stack on the platform, and a further sensor indicates that the associated shutter 39 has dropped to nip the stack. Until that stack of notes is removed it is not possible to operate the belt 250 again to move another stack of notes towards that platform 40. <IMAGE>

Title: Concrete floats and a method for their manufacture
IPC: B63B35/34
Filed: 1980-09-18
Abstract: In a concrete float having a buoyant foam core (12) surrounded by a concrete shell (24), the deck (30) of the shell has integrally formed therewith a plurality of transverse ribs and longitudinal ribs (28) which strengthen the deck and allow it to be relatively thin. Tubular conduits (not shown) extend beneath at least some of the transverse ribs to receive tie rods having their ends projecting from the sides of the float and through elongated wales which serve to secure the floats to each other. The concrete is preferably reinforced with conventional concrete reinforcing bars (32). The float is formed by placing a rectangular block of foam in a rectangular form after a bottom layer of concrete has been poured in the form with the foam core being positioned apart from the sides of the form. Transverse and longitudinal grooves are formed in the upper surface of the core, and tubular conduits are placed in at least some of the transverse grooves. Finally, sufficient concrete is poured into the foam to fill the sides and cover the upper surface of the foam thereby filling the space between the core and foam and also the grooves in the foam thereby creating the transverse and longitudinal ribs. <IMAGE>

Title: Electronic game apparatus
IPC: A63F13/577
Filed: 1982-03-11
Abstract: An electronic game apparatus having a display unit which is capable of displaying at least a series of numbers and decimal points the number of which is equal to the number of the series of numbers. Among the numbers, any number part of which is not displayed is defined as a target. The target is shifted toward one direction. With one of the function keys, a missile the shape of which corresponds to the non-displayed portion of the target is shifted toward a direction opposite to that of the target. When the non-displayed portion of the target is hit by the missile so as to complete the figure, the decimal point in an effective firing range (display frame or digit) where a missile digit and a target digit coincide disappears. Thus, points are made. The game continues until the missiles which have been given at the start of the game are used up. Points at each stage are added and final score is displayed when the game is over.

Title: Zirconium crosslinkers for solvatable polysaccharide solutions
Inventor: KUCERA CLARE H
IPC: C09K8/68
Filed: 1982-10-19
Abstract: Novel aqueous crosslinked gels which are useful for fracturing subterranean formations are comprised of a solvatable polysaccharide and a soluble zirconium crosslinking agent. The zirconium crosslinking agents are novel and are prepared by reacting a zirconium alkoxide with certain alkanolamines under anhydrous conditions. The zirconium compounds are activated by contact with water. As an example, a zirconium crosslinker was prepared by reacting zirconium tetra(n-propoxide) with triethanolamine in an n-propanol solvent under anhydrous conditions. The zirconium compound thus prepared was activated with water and used to form a stable aqueous crosslinked gel by blending the aqueous crosslinker into an aqueous hydroxypropylguar solution.
