Abstract: ABSTRACT OF THE DISCLOSURE           An inflatable multi-celled cushion device having a base formed from a fluid impervious material and provided with at least one cavity isolated from the surrounding atmosphere and capable of retaining fluid under pressure.  A plurality of cells formed from a fluid impervious flexible material are connected to the base.  The cells have hollow interiors isolated from the surrounding atmosphere which open into the base cavity so that the cell interiors communicate through the base cavity.  The cells have side walls opposite those of adjacent cells.  The cells, when deflated, are generally spaced-apart and have flutes along their side walls, with the flutes of each cell generally parallel and arranged around the entire cell and extending away from the base.  The cells are flexible enough that, when pressurized, they will expand laterally so that the flutes are generally obliterated and the side walls of adjacent cells are in contact for substantial portions of their length so as to interfere with each other.  The cells are such that, when pressurized further, their ends present a generally continuous outwardly facing surface which will con-form to the shapes of objects brought against it.

Abstract: ABSTRACT OF THE DISCLOSURE      Alternating current capacitance measuring bridge for measu-ring the capacitance of capacitors having one electrode connected to an external earth.  It comprises a first metal screen box con-nected to the common terminal of the secondary windings of a differential transformer and directly to screened coaxial connec-tions of capacitors inside of which an alternating voltage source and the transformer are placed, and means for d.c. supplying the source via internal d.c. supply terminals comprising a first win-ding connecting to the common terminal of secondary windings and the external earth, a second and third windings connecting to the internal d.c. supply terminals and external d.c. supply terminals, the first, second and third windings having a high impedance at the operational frequency of the source, two capacitors of high impedance inserted between the internal d.c. supply terminals and said first screen box, and tow other capacitors of high impedance inserted between the external d.c.  supply terminals and the ex-ternal earth.  In addition, the measuring bridge comprises a second metal box screen containing all the elements of the measuring bridge and connected to the external earth.  The screened coaxial connections comprise either  external conductors connected to the external earth, or internal conductors connected to the first metal screen box and external conductors connected to the exter-nal earth, so as to eliminate mutual capacitance errors coming from induced currents between conductors of the screened coaxial connections.

Abstract: ABSTRACT OF THE DISCLOSURE :       This invention is concerned with a method for continuous hydrolysis of a vegetable solid pentosan containing material in a temperature range between 80° and 120°C, and at a pH lower; than 5, with extraction of a usable hydrolysis residue by feed-in of raw  material at one end and feed-out at the other end of a hydrolysis vessel. According to the invention, parts of the hydrolysis fluid are recirculated into the hydrolysis vessel at two different concentrations at different or identical level, and the supplementation necessary for hydrolysis of the fluid quantity takes place together with the recirculated hydrolysis fluid having the lower concentration.  This method advantageously allows both the hydrolysis products and the hydrolysis residue to be recovered and used in a manner which is economically favorable.  The apparatus for carrying out this method is also disclosed.

Abstract: DUAL TIMER WITH DELAY          ABSTRACT OF THE DISCLOSURE               A solid state dual timer with adjustable "long" and "short" time intervals preferably providing a long normally operating period between consecutive test periods which are utilized for test purposes, wherein a "delay" interval is provided at the initiation of each test period to allow the test conditions being imposed a sufficient time to settle.  A highly advantageous application resides in the field of auto-mated lubrication systems in which periodic pressure tests to monitor system integrity are performed, for example, every hour, the tests requiring a relatively brief time interval, the "delay" interval being of a length sufficient to allow the system pressure to build up before the test instruments are activated.  The normally operating interval and the test and "delay" periods are all adjustable.             The present invention relates to timers and more particularly to a novel solid state dual timer with a capability of providing a "delay" interval at the initiation of each test period interval and especially adapted for use, for example, in monitoring a cyclic fluid pressure condition.

Abstract: Title:         "Automatic Safety Brake for Chain Saw"  Inventor:         Henry C. Fuller Abstract of Disclosure A chain saw with a safety brake includes a cutter bar which is pivotally connected to the saw frame.  A brake band arranged around the clutch hub of the gear sprocket has one band end connected to the frame and the other band end connected to the pivotal cutter bar.  A sprig between the saw frame and the cutter bar urges the cutter bar about the pivot to a safety position in which the brake band grips the clutch drum and prevents chain movement.  Manual pressure of the cutter bar against the work material overcomes the bias of the spring to pivot the cutter bar to the working position and release the brake band and enable The cutting chain to travel.  Release of pressure on the cutter bar as for in-stance when the bar severs the work material causes the cut-ter bar to return to the safety position under spring bias, with the brake band engaged with the clutch drum and chain movement stopped.  Manual overrides are disclosed to enable chain movement when the cutter bar is not pressed against the work.

Abstract: ABSTRACT OF THE DISCLOSURE An actuator for converting linear motion to alter-nating, opposite direction, rotary motion.  The actuator is electrically operated and selectively activatable to produce rotary motion in a desired direction via separately incor-porated electrical circuits.  Included is an electric solenoid operated plunger which reciprocates a rotatable cam.  The cam both drives a rotatable pivot member in alternating, opposite directions via cam followers and completes one or the other of two electrical circuits depending on the rotational position of the pivot member. The solenoid is activatable to produce rotational motion in a desired direction only if the cam is completing the appropriate electrical circuit.  The cam is supported by a housing and is positioned for re-engagement with one of the pivot member cam followers by the housing after each stroke of the solenoid.
