Filed: 1988-08-05
Abstract: The self-steering axle assembly includes a transverse axle member extending below the vehicle frame, either forwardly or rearwardly of the vehicle rear wheels (18), a king pin assembly on each of the opposite, outer end portions of the axle member, a wheel rotatably mounted on each of the king pin assemblies for steering movement and a tie rod interconnecting the wheels so they steer together. The axle member is supported from the vehicle frame for pivotal movement of the king pin assemblies relative to the frame between a forward position wherein the longitudinal axes of the king pin assemblies are upwardly inclined in a rearward direction at a forward angle of less than about 30° relative to a vertical plane passing through the rotational axes of the wheels and a reverse position wherein the longitudinal axes are upwardly inclined in a forward direction at an angle of less than about 30°. The king pin assemblies are selectively moved between the forward position for forward movement of the vehicle and the reverse position for backing, so that the wheels track vehicle movement in both directions.

Abstract: The diamond-clad machining tool of the invention is prepared by the steps of (a) forming a film (2) of diamond of 10 to 1000 µm thickness by the method of vapor-phase deposition on the surface of a temporary substrate (1) of, e.g., silicon, (b) bonding the diamond film as borne by the temporary substrate to the surface of a base body of the tool (3) by brazing (4) and (c) removing the temporary substrate (1), e.g., by grinding to leave the diamond film (2) bonded to the base body of the tool by brazing. The method is advantageous in the versatility in respect of the material of substrate (1) on which a diamond film (2) is deposited from the vapor phase as well as in the firmness of bonding between the cladding layer (2) and the base body of the tool (3) in comparison with the conventional vapor-phase deposition method of diamond directly to the surface of the base body of a tool.

Abstract: Methods and apparatus are disclosed for transferring data to and from a first bus, to which a first set of high performance devices, including at least one central processing unit ("CPU") is attached, and a second bus, to which a second set of relatively lower performance devices is attached. More particularly the invention accomplishes the aforesaid transfer function in a manner that facilitates communication between the first and second set of devices from the comparatively lower performance of the second set of devices. According to the preferred embodiment of the invention, direct memory access ("DMA") apparatus and methods are disclosed, including a set of direct memory access channels. The DMA channels may be used to transfer data between the high performance channel (hereinafter referred to as the "Local Bus") coupled to the CPU in a reduced instruction set computer (RISC) system and a typically lower performance, peripheral bus (hereinafter referred to as a "Remote Bus"). The resulting DMA interface between the Local Bus and a Remote Bus permits a wide perfor­mance range of standard peripheral devices to be attached to the RISC system in a manner that does not limit system performance. The novel DMA may also be used as part of a data transfer controller (DTC) having other components, such as I/O ports, or may be used independently for transferring data between unmatched buses in, or example, computer systems, data transmission systems and the like.

Abstract: A method of measuring acoustic vibrations affecting the fluid in a well at a plurality of points which are angularly distributed around the axis of the well and which are in the proximity of the wall of the well by means of an apparatus including an elongate body which is rotatable about its longitudinal axis and having at least one acoustic vibation detector disposed at the end of an arm which is hinged to the body. The method of the invention is characterized by the fact that the arm (32) is moved away from the body (31) so as to place its end at a determined distance from the wall of the well, and the arm is then caused to rotate continuously about the axis while simultaneously recording the signals produced by the detector. The method is suitable for use in a relief well to locate a well which is blowing out.

Abstract: Plastic solar collector which consists of a flexible fabric plastic solar absorber (15) which is provided with a microporous heat- conducting coating (3) and enclosed hermetically in a plastic housing. The solar absorber consists of plastic tube ducts (4) which are interconnected in a communicating manner, is covered by the microporous, heat-conducting and black coating (3) and connected to the plastic tube ducts (4) in a heat-conducting manner. To cool the heat transfer medium situated in the absorber (15), a suitable fluid (e.g. water), which is located in the black microporous absorber coating (3), is evaporated on the surface by means of solar radiation (diffusion cooling). The vapour condenses on the collector housing (2), flows along the side walls, to collect in the hollow profile frame (1). By means of capillary forces, the fluid returns again from the hollow profile frame (1) into the black microporous absorber coating (3). To heat the heat transfer medium situated in the absorber (15), the precondition for heat-recovery operation is met by discharging and evaporating the fluid intended for the evaporation cooling through the vapour opening situated in the collector housing (2), and the solar energy absorbed by the black absorber (15) is transferred to the heat transfer medium inside the heat transfer medium ducts. <IMAGE>

Abstract: An electronic delay control circuit provides small, constantly variable delays to an input pulse signal without altering the pulse width of the input signal. The input pulse signal together with a first reference signal are input to three comparators (12,14,16) in parallel. The output of one comparator (12) is a pulse signal corresponding to the input pulse signal, and the outputs of the other two comparators (14,16) are tied together and input to a pulse shaping network (18) to produce delay current pulses for the leading and trailing edges of the input pulse signal. The delay current pulses are added to the output pulse signal to produce a delayed output pulse signal. The delay current pulses are a function of the amount of a constant current steered (24, 26) between the two comparators (14,16) as determined by a delay control signal.

Abstract: A machine for manufacturing a stud and eyelet assembly in a web (27) that moves continuously between the eyelet die wheel (41) and the stud die wheel (42). The eyelet magazine (55) continually supplies eyelets from an eyelet hopper to the eyelet transfer wheel (53), which in turn continually supplies the eyelets to the eyelet die wheel (41). Likewise, the stud magazine (56) continually supplies studs from a stud hopper to the stud transfer wheel (54), which in turn continually supplies studs to the stud die wheel (42). The eyelet or stud is held on the die (45, 46) of the die wheel (41, 42) and the stripper (57, 58) of the transfer wheel (53, 54) by a vacuum (60). The vacuum (60) is applied from a vacuum source through ports (81, 82, 83, 84) in each wheel to the die (45, 46) or stripper (57, 58) interface with the eyelet or stud. The vacuum in a transfer wheel operates from the point it receives an eyelet or stud from the magazine until the point where the eyelet or stud in transferred to the die wheel (42). Similarly, the vacuum in a die wheel operates from the point it receives the eyelet or stud from the transfer wheel to the time the eyelet and stud are assembled in the web at the nip (43). A single drive input rotates a gear (106) at the base of one wheel, which in turn synchronously rotates the other wheels through a gear train at the wheel bases.

Abstract: A level and edge sensitive input circuit can recognize a variety of types of input signals on an input line and provide a standard digital logic output for use within the equipment. The input circuit is formed from a bias circuit, two comparators, and a memory bit. The bias circuit applies a bias voltage to the input line. A first comparator inverts the state of the memory bit when the input signals are an increment above the bias voltage. The second comparator clears the state of the memory bit when the input signals are an increment below the bias voltage. In this way, the memory bit cycles through states which provide the desired output signals for use within the equipment.
