Abstract: ABSTRACT OF THE DISCLOSURE           A pulse hydraulic monitor comprises two barrels for alternately directing a pulsating jet of liquid onto a target, a valve means for dividing the flow of liquid having an inlet for a hydraulic liquid, and two outlets for delivering the same into the barrels, and pulse-forming means.  The pulse-forming means includes a through hollow enclosure, a separating member, two limit stops of the separating member, means for retarding the motion of the separating member.  The through hollow enclosure is in hydraulical relationship with the barrels, and the separating member is movable between two end positions relative the barrels so as to take one of these two end positions for forming a pulse when the pressure of the hydraulic liquid flowing in the corresponding barrel assumes a predetermined value.  The means for retarding the motion of the separating member is made in the form of a pipe filled with the hydraulic liquid under the pressure produced by a pressure source, or a cylindrical compression spring, or a sleeve closed by a membrane and filled with a compressed gas.  The separating member operates as a result of the liquid pressure assuming a predetermined value in the corres-ponding barrel only after when the pressure in said barrel is increased to a desired value.  The invention is useful in hydraulic winning of minerals, hydraulic engineering, and power engineering.

Abstract: INVENTION :  JUICE DISPENSING MACHINE              INCLUDING ARTICLE DELIVERY MECHANISM       INVENTORS :  JOHN KRIVEC AND ARNOLD FRISHMAN     ABSTRACT OF THE DISCLOSURE             A vending machine for dispensing freshly squeezed orange juice is described.  The vending machine includes a fruit delivery mechanism consist-ing of a rotary tumbler with a generally horizontal axis of rotation which stores items of fruit in bulk, a catcher positioned to catch items of fruit, and a delivery shute including a gating mechanism for delivering items of fruit individually at controlled intervals to a juice extractor.  A sensor detects when a cupful of juice has been received by an accumulator, and delivery of further items of fruit to the juice extractor is then discontinued and the contents of the accumulator are then emptied into a cup located at a service port in the vending machine.  This operating cycle is repeated each time coins are inserted into the vending machine.  To ensure fully automated operation without blockages, the catcher has a spring loaded, hinged flap which deflects to release fruit to the drum when fruit is jammed into the catcher, and the delivery shute has a mechanism which restricts the passage in the shute in response to the general size of fruit being delivered to ensure single file movement.  To ensure proper delivery of items of fruit to the catcher, the drum has an internal projection with a guide for directing an individual item of fruit towards the catcher and a conveying surface angled relative to the rotational axis of the drum to roll items of fruit towards the guide as they are conveyed thereby tending to seat an individual item of fruit at the guide for delivery to the catcher.

Abstract: VISCOUS OIL RECOVERY METHOD            Abstract In a thermal method for the recovery of oil from a subterranean, viscous oil-containing formation, steam in an amount ranging from 0.3 to 0.5 pore volume and an injection rate within the range of 4.0 to 7.0 bbl/day/ac.-ft. is injected into the formation via an injection well completed in the lower 50% or less of the formation and fluids including oil are recovered via a spaced-apart production well completed in the upper 50% or less of the formation.  The injection well is then shut-in for a variable time and thereafter a predetermined amount  of hot water or low quality steam is injected into the formation via the injection well in an amount ranging from 0.03 to 0.10 pore volume and at an injection rate of 1 to 2.0 bbl/day/ac.-ft.  The method is applied to viscous oil-containing formation in which either naturally occurring or induced communication exists between the injection well and the production well in the bottom zone of the formation.  The injection-well and production well are spaced apart 400 to 750 feet.

Abstract: Signal Valve for Pressure Compensated System Abstract A signal valve is connected to a supply conduit connecting a pump with a control valve for transmitting an artificial load signal to a load signal chamber of a pressure compensated unloader valve when the control valve is at an operating position and the pressure in the supply conduit is below a preselected value.  This moves a valve member of the unloader valve to a blocking position causing essentially full pump flow to be directed to the hydraulic jack for decreasing the response time in situations wherein the hydraulic jack has cavitated and no postive load pressure signal is present.

Cap means with one-way valve elements on such opposite end of the filter body permits flowof water through the filter body in one direction while obstructing reverse flowunder fluid back pressure introduced into the downstream end of the pressure vessel so as to compress the filter body axially. Back-pressure fluid also entering the narrow gap surrounding the sleeve and the pressure vessel wall helps prevent binding of the accordioning sleeve therein during compression cycles.

Abstract: Abstract of the Disclosure This invention relates to an unfoldable and lockable lightweight ladder that has a reverse S curvature so that it can be hung over one balcony to permit descent to the balcony below.  Horizontal struts improve the stabil-ity and safety of the ladder.  The process of descent can be repeated by lifting the ladder free of the balcony above and lowering it to the balcony on which the user is standing.     This invention relates to a personal fire escape ladder for apartment buildings that can be stored on the balcony of the occupant and can be used in an emergency, such as a fire, by following three simple steps.  These steps are to unfold the device, lock its main portions into a rigid assem-bly and hang it over the balcony.     Heretofore, fire exits, fire escapes and rope ladders have had limited suc-cess in providing for the speedy evacuation of a multi-level building.     The fire escape ladder of this invention has an upper section that is curved outwardly to accommodate a balcony of any configuration, that has an upper horizontal extension that rests on the balcony rail.  A lower ladder section is transversely hinged to the upper section.  This becomes a rigid assembly when locking ferrules are slid into engagement with the contiguous ladder portions adjacent the hinge points.     The upper section has bracing struts that engage the bottom of the balcony on its outer surface.  The lower section has a reverse or inner curvature to bring it within the plane of the balcony wall below.  It has horizontal end struts to engage this balcony wall.     The ladder is now in place and ready for use.  The user descends one bal-cony at a time, retrieving his ladder from the balcony above, hanging it over the balcony he is on and repeating the process.

Abstract: PROCESS FOR FREEZE DRYING CYCLOPHOSPHAMIDE   ABSTRACT OF THE DISCLOSURE A two-stage process for freeze-drying an aqueous solution of a dosage amount of cyclophosphamide to yield a hydrate of cyclophosphamide (referred to as "CPA" for brevity), comprises, in a first stage, freeze-drying asolution of CPA in combination with an excipient until the moisture content of the freeze-dried material is less than 2% by wt, based on the amount of anhydrous CPA present; and, in a second stage, rehydrating the freeze-dried material until the moisture content of the product is in the critical range of from about 2% to 7% by wt, based on the net wt of CPA product, it being essential for stability of the product that at least one sugar excipient be present. The process requires that a major amount by weight of the excipient(s) or all of it, be mannitol, optionally with an additional sugar and/or a carboxylic acid, and/or a buffer salt; and, the mannitol is present in an amount at least one-half (0.5 times) as much as the CPA (anhyd) present. To produce a dosage form of a 'plug' or 'cake' which is free of flakes and granules, or bubbles on its surface, and/or voids within the product (or "plug"), any of which are individually no greater than 2 mm in equivalent diameter ("equiv. dia."), requires a unique combination of carefully controlled process steps. The preferred CPA product obtained by the process provides a dosage amount of stable freeze-dried and rehydrated CPA as a hydrate which includes at least an equivalent amount by weight, and up to 5 times as much, of mannitol. The dosage amount may include sodium chloride to adjust tonicity, and a buffer salt to maintain pH.
