Title: Load-engaging device for hoisting concrete building elements
Inventor: JESSEN LAURIDS A
IPC: B66C1/14
Filed: 1993-10-04
Abstract: A load-engaging element (1) comprises a body having a protruding arm (7) for turning the body (6) in a hemispherical recess (4) in a concrete building element (5), said arm (7) having an abutment surface (8) abutting firmly against the surface (9) of the concrete element (5), when the latter is being hoisted. The body (6) is adapted to receive the head (2) of a lifting bolt (2,3) by means of a cut-out (11), through which the head (2) may be inserted in and removed from the slot (10). The end link (17) of a chain (16) is placed in the central slot (12) and retained by the bolt (14). When the concrete element (5) is being lifted, the pull in the chain (16) will exert a turning moment on the body (6), causing the abutment surface (8) on the arm (7) to be pressed against the surface (9) of the concrete element (5), so that the body (6) cannot inadvertently be released from the load-engaging device (1).

IPC: G02B6/38
Filed: 1995-06-06
Abstract: A bend-limiting apparatus for attachment to an optical connector has a generally cylindrical shape and includes an axial bore along its central axis for holding an optical cable. The front end of the bend-limiting apparatus attaches to the optical connector and has an outside diameter which is comparable in size to theconnector. The back end of the bend-limiting apparatus has an outside diameter which is comparable in size to the optical cable. The bend-limiting apparatus is made from a flexible material which is sufficiently stiff to accommodate heavy side loads, but includes a number of grooves that are exclusively positioned on its back half to accommodate light side loads. These grooves preferably extend from an outside surface of the apparatus into the axial bore, and also extend in a circumferential direction at least part way around the apparatus. Such a design effectively limits the minimum bend radius of an optical cable over a wide range of side loads.

IPC: C12Q1/34
Filed: 1995-07-27
Abstract: Hyaluronidase activity in human semen is found to be related to sperm concentration, motility, morphology, and the rate of fertilization in vitro. A method for assessing sperm fertilizing ability is provided. In the method, semen samples are treated with detergent to extract hyaluronidase and applied to a mixture of hyaluronic acid and agar. Enzyme activity is assessed by measuring the area of substrate hydrolysis. Hyaluronidase activity is found to be significantly related to the success of fertilization and to the fertilization rate. These results indicate that measurement of hyaluronidase activity can provide a useful method for assessing the integrity of the acrosomal enzyme system, providing a simple, reliable, and cost effective predictor of the fertilizing potential of human sperm.

Abstract: Soil adjacent to an elongated furrow is irrigated by flowing the water from a header into and along the furrow, and erosion of the furrow is reduced and infiltration into the soil is increased by dissolving solid flocculant in the header or in the furrow into the water. The solid flocculant is best provided as a block of particulate flocculant bonded by a water-soluble wax. The irrigation process is best conducted on a cyclic basis with the solid flocculant being removed from the header or furrow during the cycle and with the supply of water being continued so that there is subsequent run-off of water from the furrow.

Inventor: OFFICER TODD M
IPC: F16H59/32
Filed: 1996-05-24
Abstract: A method for shifting a powershift transmission of a vehicle in accordance with the load being experienced by the engine as estimated from certain engine operating parameters. A turbocarger associated with an engine operating at a given engine speed generates a turbo boost pressure. The turbo boost pressure is monitored by a sensor and a turbo boost signal is generated therefrom. Similarly, the engine speed is monitored by a sensor and an engine speed signal is generated therefrom. The turbo boost and engine speed signals are used to estimate the engine load based on empirical data stored in the transmission controller's memory, and a percentage load is computed therefrom. The percentage load is then used to generate an appropriate duty cycle and time value for a pulse-width-modulated shift signal which controls the modulation of an on-coming directional clutch into engagement at a desired rate of engagement dependent upon the load being experienced by the vehicle.

Title: Apparatus and method of reducing the force to expel a tampon from a tampon applicator and the applicator itself
Inventor: TEWS RICHARD ROY
IPC: A61F13/26
Filed: 1995-07-21
Abstract: An apparatus and method are disclosed for reducing the force required to expel a catamenial tampon from a tampon applicator. The tampon applicator is also disclosed. The tampon applicator includes a first member which is capable of housing an absorbent tampon. The first member has an inside diameter, first and second spaced apart ends, and an insertion tip formed adjacent to the first end. The insertion tip at least partially closes the first end of the first member and facilitates insertion of the tampon applicator into a woman's vagina. The insertion tip is opened, expanded and reclosed prior to positioning the tampon in the first member. This action allows the insertion tip to be reopened with a minimum amount of expulsion force. The apparatus includes a first punch having an outside diameter which is sized slightly less than the inside diameter of the first member. This enables the first punch to slide within the first member from the second end toward the first end. The first punch has a forward end which is capable of opening the insertion tip. The apparatus also includes a second punch having a forward end with an outside diameter which is sized larger than the inside diameter of the first member. The second punch is capable of entering the opened insertion tip and expanding at least a portion of the inside diameter thereof. The method discloses using the above-mentioned apparatus as well as the step of reclosing the insertion tip such that a reduced force is required to reopen the insertion tip and expel the tampon.
