Title: Rain responsive windshield wiper control
Inventor: TEDER REIN S
IPC: B60S1/08
Filed: 1990-12-18
Abstract: A control circuit for a windshield wiper motor is disclosed in which the wiper motor is made automatically responsive to the presence of moisture droplets on the windshield causing the wiper blades to sweep back and forth at a rate dependent upon the level of precipitation encountered. By using a set of sample-and-hold circuits, bandpass filtering and a differential amplifier under microprocessor control, disturbances to the system due to changes in ambient light are linearly rejected and the system becomes immune to such disturbances. The system utilizes an intentional-retrigger algorithm enabling the system to detect water droplets that miss the sensor yet fall within the area of the windshield which is swept by the wiper blades. The system automatically adapts to windshields of differing transmittance and is not falsely set into action by electromagnetic disturbances.

Abstract: F-5726;           METHOD OF PREHEATING A HEAVY OIL ZONE THROUGH EXISTING BOTTOM WATER AND THEM    DIVERTING STEAM INTO THE OIL ZONE          ABSTRACT     A method for recovering viscous oil from a formation having a bottom water zone below an oil containing zone. Steam is directed into the bottom water zone thereby heating this zone and an oil containing zone thereabove. Afterwards, steam injection is ceased and a gellable composition is directed into the bottom water zone where it forms a solid gel. Once the solid gel has formed, steam is injected into the bottom water zone where the solid gel causes it to flow  upwardly into the oil containing zone. Oil, water, and steam are removed via a recompleted producer well.

Abstract: A bone anchor (10) for securing a suture to a bone (38). The bone anchor (10) has a tip (16) at its distal end (18) and at least one resilient wall (27) extending to a trailing end (20) of the body (12) of the anchor. The wall (27) has a ridge (14), or barb, formed on an outer surface. The ridge (14) defines an edge (34) that digs into a hole (36) in the bone (38) in which it is positioned. A strand of suturing thread (22) extends through a suture receiving opening (24) in the tip (16) of the anchor. The method. of the present invention employs the suture anchor (10) and includes the steps of forming a hole (36) in a bone (38) and inserting the suture anchor (10) to a desired depth in the hole (36) in the bone (38) using an inserter device (100). Suturing thread (22) extends from the suture receiving opening (24) in the tip and along the length of the walls (27,28) out of the hole (36) in the bone (38). An anchor spreader (130) is used to firmly seat the anchor (10) in the hole (36).      The suture (22) is pulled at the same time to help seat the barbs 14 on the anchor (10) into the bone (38).

Title: Drying
Inventor: GLOVER EDWARD C T S
IPC: F26B13/10
Filed: 1990-02-08
Abstract: It is known to dry photographic paper using radiant heat and air streams passing over the surface of the paper. However, it is important that the paper is not over- or under-dried. Described herein is a method and apparatus which dries photographic paper without the risk of over- or under-drying it. This is achieved by sensing the moisture remaining in the paper after it has passed through an initial heating stage, and using the sensed moisture content to control the power supplied to heaters and other devices in subsequent heating stages which assist in the removal of moisture from the paper.

Abstract: ABSTRACT          In a racquet, in particular, a tennis racquet, which incorporates a frame, an open and closed heart piece, and a shaft (2) that is joined to the heart piece, with the frame, heart piece and shaft being formed in one piece or connected releasably to each other, the grip (1) that is formed as a one-piece sleeve can be slid onto the shaft.  The inside profile of the cross section of the grip (1) and the outside profile of the cross section o* the shaft (2) incorporate longitudinal shape-locking and interacting supporting surfaces.  The spacing between the supporting surfaces on the shaft (2) and the supporting surfaces of the grip (1) tapers in a wedge shape towards the unattached end (11) of the shaft (2).  A removable distance piece (3) that prevents the grip (1) being slid axially into the mated position is releasably connected to the end (11) of the shaft.  With the distance piece (3) installed on the shaft, the racquet can be tested with various grips (1).  After removal of the distance piece (3) the grip is slid completely onto the shaft (2) and is then joined to this so that, for all practical purposes, it cannot be released therefrom.
