Abstract: ABSTRACT OF THE DISCLOSURE     An improved closed-loop hydrostatic transmission system is provided of the type including a pump (11), a motor (13), and a pair of conduits (15 and 17).  The system includes a main control valve (43) and a charge pump (23) which is the sole source of make-up fluid to the closed-loop system and the sole source of control fluid for varying the pump.  The system includes a power limiting means comprising first and second pressure relief valve means (75 and 77) operable to provide fluid communication from whichever side of the closed-loop is at high pressure to the system reservoir whenever system pressure exceeds the predetermined maximum pressure.  The motor is adapted to transmit drive torque to a reversible load (37) of the type having a known inertia and a predeterminable time of deceleration from maximum speed operation in one direction to a standstill condition.  A flow restriction means (44) in series relationship between the charge pump and a fluid pressure responsive means (31,33) of the pump is selected such that reversal of the main control valve (43) from maximum displacement in one direction to maximum displacement in the opposite direction results in destroking of the pump in a time period approximately equal to the time of deceleration of the reversible load, thereby substantially preventing cavitation and high-pressure spikes.

Abstract: A process for production of chlorine dioxide by reacting in a reaction vessel an alkali metal chlorate, a mineral acid and methanol as a reducing agent in proportions to generate chlorine dioxide in a reaction medium maintained at a temperature from about 50 DEG C to about 100 DEG C and at an acidity within the interval from about 2 to about 11 N and subjected to a subatmospheric pressure. Thereby water is evaporated and a mixture of chlorine dioxide, water vapour and gaseous by-products is withdrawn from an evaporation region in the reaction vessel. The alkali metal sulphate is precipitated in a crystallization region in the reaction vessel. The content of formic acid in the reaction vessel is increased by addition of formic acid to a content of formic acid exceeding about 0.3 M. The gaseous by-products are condensed to obtain formic acid and the content of formic acid in the reaction vessel is increased by recirculation of the condensate.

Date Oct. 27, 1994A method and apparatus to clean a filter drum used for thickening lime mud. The drum is rotated about a horizontal axis in a first direction so that the circumferential surface of the drum moves into contact with lime mud in a vat and a precoat layer formed on the drum, as well as an external layer of lime mud which forms a thickened lime mud cake when a vacuum is applied to the drum withdrawing liquid from the lime mud. The thickened external layer of lime mud cake is scraped from the drum at a second side of the vat, and at a first opposite side of the vat a first jet of liquid is directed onto the drum surface (e.g. at a pressure of about 30-100 bar) to remove a strip of the precoat layer, a third jet of liquid cleans the drum after removal of the precoat layer, and a second jet of liquid is directed onto the drum with sufficient intensity (e.g. a pressure of about 2-20 bar) to remove, by spreading and partially detaching, a strip from the thickened lime mud cake. Typically the second jet is operated substantially continuously, except when the first and third jets are operated, the first and third jets being operated at spaced time intervals (e.g. periodically or intermittently). The invention results in partial removal of the precoat with a gentle liquid jet, easy removal of the entire precoat layer because the precoat is not yet hardened at its location of movement, intermittent use of high pressure jets which extends the life of the high pressure apparatus in the wire forming the drum, and optimum ease of installation and maintenance of the spray nozzles.

Abstract: A massaging pad is pressed against discrete areas of a subject person's scalp and worked from side to side to thereby move the skin relative to the underlying skull. The pad (20) is cloth material that is compressible as necessary to avoid the discomfort of pressing a hard metal probe against the scalp. Electrical current is passed through the pad and into the subject person's scalp by connecting the pad to an electrical conductor from an electrical current generating device (12) which generates oscillating voltage to the pad in a low range and at a variation of voltages. The pad includes a highly conductive metal bulb, e.g. of copper metal coated with silver and gold, and a moistened padding, e.g. wool that surrounds the bulb. The ground contact is hand held by the subject person so that electrical current is directed down through the skin layers during the massaging process.

Abstract: Tracheostomies can be formed by means of a hollow needle inserted through a scalpel cut into the trachea.      In the present invention, the needle has a sharply pointed tip and is joined at its rear end to a plastics hub. The length of the needle from the hub is greater than the thickness of neck tissue but less than the distance between the skin surface and the posterior wall of the trachea. The hub has a laterally extending face which has an area at least fifty times the cross sectional area of the needle. Two parallel walls with stepped edges provide a gripping region far the hub, enabling it to be gripped between the finger and thumb. The needle is inserted by means of a loss of resistance device in the form of a syringe the nose of which is coupled in a tapered recess in the hub. When the plunger of the syringe can be displaced along its barrel, this indicates that the tip of the needle has entered the trachea.

Title: Self-locking bill accumulator
Inventor: HARRIS ROBERT R
IPC: G07D11/00
Filed: 1990-03-14
Granted: 1994-08-23
Abstract: A self-locking bill accumulator having tamper-proof features is provided for use with a dollar bill processing machine.  During use, the bill accumulator is mounted to a bill processing machine. The accumulator has a double locking feature whereby rotation of an outer lock by means of a key is required in order to detach and remove the bill accumulator from the dollar bill processing machine.  This rotation of the outer lock occurs prior to removal of the bill accumulator and causes a corresponding rotation of an inner lock, which in turn positively locks the bill accumulator to protect bills in the accumulator from pilferage after removal.  Upon removal of the bill accumulator, the outer lock becomes disengaged from the inner lock such that a separate key is required in order to "unlock" the bill accumulator and remove the bills.

Granted: 1994-10-18
Abstract: An injector has a solenoid armature that displaces a valve from its seat to deliver a charge of fuel and air directly into the combustion chamber of a two-stroke cycle internal combustion engine.  When a valve return spring closes the valve against its seat to terminate delivery of the fuel-air charge, the armature separates from the valve stem, and the kinetic energy of the armature is dissipated by a resilient disk or ring.  An adjustment is accessible at the end of the valve stem to establish the valve closing force of the return spring, an adjusting screw establishes the distance between the open and closed positions of the valve, and another adjusting screw positions the resilient disk.
