Abstract: A heave compensator is disclosed particularly adapted for use in compensating the flow through a riser pipe employed in offshore drilling apparatus for surges and ebbs produced in the flow therein by the rising and falling of the surface platform or vessel in relation to the ocean floor. A telescoping section substantially identical to that incorporated within the riser is carried by the floating platform or vessel at a location remote from the telescoping section of the riser. The compensating telescoping section is connected into the flow pipe on one end and closed at the opposite end. The two telescoping sections are disposed normal to the earth's surface whereby gravity tends to extend the compensating telescoping section. The two lower portions of the respective telescoping sections are interconnected by a flexible cable passing over a sheave carried by the platform or vessel.

Abstract: The present exercising device includes a swivel platform and hand-held control cords which may be operated through a pulley assembly. The swivel platform is made up of a large diameter circular platform rotatably mounted on an equal diameter circular base. The base is similar in shape to an oversized ping pong paddle with a circular head portion and an extending member corresponding to the handle of the paddle. The hand-held cords are connected either directly to the end of the extending member of the base or to pulleys secured to the extending member, to provide balance and coordinated rotation of the swivel platform. When pulleys are used, the two hand-held cords are each run through one of the two pulleys, and then connected to each side of the swivel platform. Each cord may be attached to one of two arms extending laterally from the swivel platform, or to the eyebolts connected to opposite sides of the platform. The cords can be adjusted to fit persons of all sizes.

Abstract: Novel apparatus is described for controlling the application of circuit adjustment signals to an electrical circuit device. The same device leads are used in an operating mode with input signals in a first range, and in an adjustment mode with input signals in a second range, the two ranges being mutually exclusive.An exemplary embodiment is directed toward trimming a digital to analog converter. A plurality of trimming elements are provided with an equal number of two-terminal actuating devices, which are arranged in a matrix such that each pair of terminals is connected in circuit with a unique pair of input leads. The devices actuate their associated trimming elements in response to the application of actuating signals, exceeding a threshold level greater than the level of the binary input signals, to their respective lead pairs. The leads are thereby capable of a dual mode operation, with one mode for normal converter operation and the other mode for setting up desired trim circuits.

Abstract: Scrubbing and drying apparatus particularly suited for use in scrubbing and drying printed circuit boards is disclosed. The apparatus is characterized by single knob precision adjustment of the scrubbing rollers incorporated therein and quiet operation at noise levels well within employee noise safety limits by the elimination of high pressure air nozzles typically employed in such scrubbing and drying apparatus according to the prior art. A novel anti-sway mounting is employed in conjunction with the scrubbing rollers to affect the single knob adjustment capability. A chamois covered roller is used to blot the surface of the board of substantially all its water content prior to final drying by low pressure airstreams.

Abstract: The heavy iron gratings for a burglar-proof window are pivotally mounted on one side. The other side is provided with a latch type locking mechanism using a plunger having a ramped surface to hold a set of ball bearings in locking engagement with a matching cylinder. A small carbon dioxide container is mounted within the latch and is spring loaded with a detent arranged for actuation from within the home which is being protected. When the detent is released, a spring-loaded plunger punctures the carbon dioxide container, and a ramped latching plunger is moved to release the locking ball bearings, and then the iron grating or barrier is then vigorously swung open by the pneumatic pressure from the punctured container.

Abstract: A safety belt retractor has a belt storage spool and a spool rewind spring for biasing the spool in a belt rewind direction, means for reducing the tension applied to the belt when in use due to the bias of the rewind spring, means for activating such means for reducing in response to spool rotation in a predetermined manner and means for deactivating such means for reducing in response to spool rotation in a belt rewind direction of more than one full revolution of the spool under the influence of said reduced tension. The means for reducing the resultant effect of the rewind bias of the spring in an exemplary embodiment includes means for selectively applying a portion of the rewind torque of the spool rewind spring back on to the spool through a gearing arrangement in one version, and through a pulley means in another arrangement, in a belt unwinding direction to produce a reduced torque or "comfort zone" effect upon the spool.

Abstract: A universal and economical drawer slide is mounted on the rear underside of a pull drawer to engage a fixed cabinet side member or channel. The preferred embodiments disclosed in the present application are rectangular in shape and are intended for use with furniture-type drawers which have a recessed drawer back, with the thin bottom of the drawer secured into the recess in the drawer back. By making the drawer guide rectangular in configuration, it may be thinner at the rear and therefore may be used with a furniture-type drawer with a cutting away of only a short section in the center of the bottom of the drawer back. The cabinet guide members may be made of wood or of metal channels, and include laterally extending side rails which are engaged by the molded plastic drawer guide which is secured to the rear portion of the drawer. The drawer guide includes a generally rectangular flat, thin plastic body, with a flange which extends upwardly and over the outer side of the back portion of the drawer.

Abstract: In the replacement of the hip joint, full access to the hip joint is obtained by separating the trochanter, a large protruberance on the upper portion of the upper leg bone, or femur, from the remainder of the femur, and the subsequent dislocation of the hip joint. Following dislocation, a minimum amount of bone is removed from the femoral ball and sufficient bone is removed from the socket to accommodate the minimum thickness surface replacement elements. A thin hollow inert metal ball or shell member having an outer diameter close to that of the original hip joint is then cemented onto the upper end of the femur, and an ultra high molecular weight polyethylene cup is cemented into the hip bone socket, with acrylic bone cement. To achieve maximum strength with minimum thickness, both the metal and plastic surface elements, although spherical at their mating surfaces, are thicker at their maximum load bearing points toward the top, and are of lesser thickness elsewhere.

A mandrel, which may be changed without the need for external tooling, is positioned in the aperture in the anvil, the mandrel having an externally threaded portion extending outwardly of the anvil and a socket facing into the bore. A shaft is rotatable and reciprocable in the bore of the body member which shaft is provided at one end with a key which fits into the socket on the mandrel in driving engagement therewith, the key being interchangeable without the need for external tooling.
