Title: Determining the position of a pile
Inventor: ENGLAND MELVIN GERRARD
IPC: E02D13/06
Filed: 1991-12-12
Abstract: A method and apparatus for determining the position of a pile or ground treatment apparatus or of an elongate element, generally while the pile or the like is being driven into the ground by means of a hammer or the like, is disclosed. The method involves measuring the time to receive the acoustic signal emitted due to the impact of the hammer on the object and comparing this with a reference signal. The difference in times will indicate the progress of the pile and hence the point at which it reaches the limit of its travel. A method of indicating ground conditions is also disclosed, involving the comparison of the time the stress wave induced in the pile takes to propagate up said pile with the propagation time of the partially reflected stress wave. This method can also be used to determine the depth of the pile below ground.

Inventor: HAMADA TETSUROU
IPC: F16D43/284
Filed: 1992-07-03
Abstract: A power transmitting system of a four-wheel drive vehicle having primary driven wheels driven directly by a prime mover, and subsidiary driven wheels driven through a hydraulically actuated friction clutch. The power transmitting system comprises a first hydraulic pump driven in operative association with the primary driven wheels and a second hydraulic pump driven in operative association with the subsidiary driven wheels. Each hydraulic pump (Pf, Pr) has a pair of ports (10, 11; 12, 13) which serve as an intake and a discharge with the functions of such ports (10, 11; 12, 13) being reversed between forward and backward movement of the vehicle. A first oil passage (14) connects the intake port (12) of one pump (Pr) with the discharge (10) of the other pump (Pf) and a second oil passage (15) connects the discharge (13) of the one pump (Pr) with the intake (11) of the other pump (Pf). Third and fourth oil passages (17, 18) connect the first and second oil passages, respectively, with a working hydraulic pressure chamber (16) in the hydraulic clutch. A one-way valve (19, 20) is provided in each of the third and fourth oil passages (17, 18) for permitting only a flow of oil toward the working hydraulic pressure chamber (16). The reversal of vehicle movement and direction of oil discharged from each of the hydraulic pumps (Pf, Pr) provided in the power transmitting system of the four-wheel drive vehicle is compensated for by a simple structure of oil passages and one-way valves which varies the force on the hydraulic friction clutch. <IMAGE>

Title: Absorption heat pump
Inventor: HEMSATH KLAUS H
IPC: F25B15/04
Filed: 1993-09-09
Abstract: A low cost absorption heat pump includes a pressure vessel (20) having first and second insulated compartments (22, 23) in unrestricted fluid communication with one another and containing, hermetically sealed, a working medium. The working medium comprises two fluids, one fluid having a low boiling temperature and the other a high boiling temperature. A heat transfer arrangement is used to maintain the compartments at differential temperatures, but equal pressures, so that the absorption cycle proceeds in a two-stage, batch mode, namely boiling of the working medium in the first compartment and simultaneous condensing in the second compartment during the first stage and evaporating in the second compartment and simultaneous absorbing in the first compartment during the second stage. The heat transfer arrangement utilizes the heat given off or taken in during the absorption cycle for heating/air conditioning purposes. Periodically the working medium is rectified by pumping any working medium in the second compartment back to the first compartment after a predetermined number of cycles have been completed. The pressure vessel may comprise two interconnected rotating compartments. <IMAGE>

Title: Insect feeding station
Inventor: GENERO CLAUDE PAUL
IPC: A01M1/20
Filed: 1992-07-10
Abstract: An insect feeding station (10) for administering a fluent substance such as a poisonous liquid bait to ants and other insects. The feeding station (10) comprises a housing (11) having an interior region (21) adapted to contain the fluent substance. The housing (10) has an opening (27) through which insects can enter and leave the interior region (21), and an internal structure (43) within the interior region (21) for facilitating access by the insects to the substance. The internal structure (43) may take various forms but typically is of a construction which is adapted to at least be partially covered by the substance when the latter is first introduced into the interior region (21) and which is progressibely exposed as the substance is consumed. With this arrangement, the portion of the internal structure which is exposed provides a zone away from the liquid bait for supporting the bodies of dead insects. Thus the bodies are "dry-docked" on the internal structure from where they can be retrieved. <IMAGE>
