Title: Process for the preparation of 2- substituted-4-hydroxy-2-cyclopenten- 1-ones
IPC: C07C309/73
Filed: 1981-03-24
Abstract: Compounds of the general formula:-   <IMAGE> (which are valuable intermediates in the production of prostaglandins) are produced from compounds of the general formula:-   <IMAGE> in which     R represents hydrogen or a lower alkyl radial; A represents a hydrocarbon chain containing 5, 6 or 7 carbon atoms, which chain may contain at least one alkenylene or alkynylene group and may be substituted with one or more lower alkyl groups; and OTrialylBS represents a tri C2-6 alkyl benzene sulphonyl group by reduction with alkali metal borohydride with subsequent hydrolysis and allylic rearrangement. In an example the triisopropyl benzene sulphonate of 2-(6-carbomethoxyhexyl)-4-hydroxy- cyclopenta-1,3-dione is reduced with NaBH4 and hydrolysis and allylic rearrangement, which occurs spontaneously in an acid medium gives 2(6- carbomethoxyhexyl)-4-hydroxy-2- cyclopenten-1-one in high yield.

Patent GB-2099043-A (GB)
Title: Running and release tool
IPC: E21B23/02
Filed: 1981-05-26
Abstract: A running tool, for depositing an instrument package in a landing nipple within a well pipe line by means of a hanger having a nipple at its upper end, comprises an inner longitudinal body 11 having a collet clamp, or annular latch, 3 fast therewith at its bottom end and an annular piston 16 mounted fast therewith intermediately along its length. The tool further comprises an outer sleeve 1 which extends substantially over the length of the tool and houses the longitudinal body 11. The sleeve has an internal flange 17 which provides an abutment supporting a compression spring 30 lodged between the flange 17 and the annular piston 16. At the bottom end of the tool the sleeve 1 receives the stepped diameter portion of the collet clamp 3 with minimum clearance and under the biasing action of the spring 30, thereby providing positive clamping action of the collet clamp. When a pull is exerted on the member 4 relative to the longitudinal body 11, as will happen when a hanger fastened within the collet clamp is lodged in the landing nipple, the longitudinal body is pulled partially out of the sleeve so that the adjacent end of the sleeve clears the stepped diameter portion of the collet clamp thereby releasing the hanger nipple. The clearance between the piston 16 and the sleeve is adjusted so that oil within the tool has a restricted passage from one side of the piston 16 to the other thereby controlling the relative displacement of the two parts of the tool when a pull is exerted upon it. This prevents mechanical shock being imparted to the instrument package when the hanger is released from the tool. <IMAGE>

Title: Fluid displacement well safety valve
Inventor: PRINGLE RONALD EARL
IPC: E21B34/10
Filed: 1981-12-18
Abstract: A well safety valve 10 for controlling the fluid flow through a well conduit comprises a housing 12 and a spring-biassed flow tube 22 controlling a valve element 18. A gas chamber 34, 38 is positioned in the housing with a fluid passageway 44, 46 positioned between the gas chamber and a port for receiving fluid pressure from the well surface for increasing the pressure of the gas in the chamber.

Title: Starting aid system for compression-ignition engines
IPC: F02N19/04
Filed: 1982-05-19
Abstract: The system includes an electric starting aid 4 of the kind mounted in the inlet manifold of the engine and including an electric heating element which, in use, vaporises and ignites a fuel to pre-heat the air flowing to the engine cylinders. The system also includes a valve 6 for controlling fuel flow to the aid and a switch circuit 74, 75, 64 which when operated causes supply of current to the aid. The heating element of the aid is rated so that it can reach the operating temperature quickly and a temperature analogue circuit including a capacitor 65 and a comparator 68 controls the state of the switch circuit so that the desired operating temperature is maintained. A timer 71 controls the operation of the valve 6 and also the switch circuit 74, the timer itself is controlled by a switch 73 which is closed when the starting motor of the engine is operative and also when a temperature sensor 72 senses that an engine temperature is below a predetermined value. <IMAGE>

Title: Apparatus for making sealed packages for spreadable products
Inventor: REDMOND SANFORD
IPC: B65B25/06
Filed: 1982-12-20
Abstract: Apparatus for making sealed packages for spreadable products 6 includes means 110 for transporting a relatively stiff base member 112 carrying a spreadable product 6 in the approximate center thereof, means 44 for feeding a relatively thin flexible sheet material 36 and for cutting such flexible material into predetermined lengths and for feeding such cut lengths to a rotatable vacuum drum 56 having a plurality of die stations. A first tamper 74 cooperates with the die as the stations rotate past the tamper to shape each cut length of flexible material into a predetermined three-dimensional form, which is then transported by the vacuum drum to a position over the stiff base and the spreadable product thereon where the formed flexible sheet is released by the vacuum drum and cohesively joined along its outwardly extended edges to the base member to enclose the spreadable product positioned thereon. The longitudinally extending edges of the flexible sheet and base member are further pressed into cohesive engagement by a roller assembly 91 which contains resiliently mounted blades which further compresses the leading and trailing edges into cohesive engagement. A final tamper 132 then tamps the pleats shut. <IMAGE>

Title: Peristaltic pump
Inventor: GRANDE PER-OLOF
IPC: F04B43/12
Filed: 1982-05-27
Abstract: A peristaltic pump comprises at least two elastically compressible hose conduits (6), each having an inlet end and an outlet end and mutually identical cross section, a support means for each hose conduit (6), said support means having a curved surface (4) which is similar for all the hose conduits and which is engaged by the associated hose conduit (6) with at least a portion of the length thereof and at least two synchronously driven rotor units (1), one for each hose conduit (6), which are provided with the same number, at least two, of symmetrically arranged and mutually at the same distance from the rotor axis (2) operating pressure means (3) for local compression of the hose conduit (6) corresponding to each rotor unit (1), against the curved surface (4) of the associated support means. The number of pressure means (3) on each rotor unit (1) and the extention of said curved surface (4) on the support means of each hose conduit (6), seen in the longitudinal direction thereof, are mutually so adapted that continously one of the pressure means (3) on each rotor unit (1) compresses the corresponding hose conduit (6) for preventing fluid flow through the hose conduit in a direction opposite to the direction of rotation of the rotor unit. In order to provide a peristaltic pump permitting a non-pulsatile flow, at least the outlet ends of the hose conduits (6) forming part of the pump are joined into a common outlet (7) in a manner known per se, and the synchronously driven rotor units (1) are angularly displaced relative to each other such that their pressure means (3) operate with phase displacement on each hose conduit (6), whereby the flow pulsations generated in each hose conduit will at least to a substantial extent neutralize each other at the common outlet (7) of the hose conduits (6).

Title: Ignition system for an internal combustion engine
Inventor: FRITZ ADOLF
IPC: F02P11/02
Filed: 1984-02-08
Abstract: The ignition system comprises a speed limiting circuit 28 including a speed monitor 29. When a maximum admissible speed is reached, the monitor 29 disconnects a control terminal 30 from the earth lead 2. At the breakdown of a zener diode 40, a transistor 31 is switched on thereby switching off a transistor 37. In consequence, the voltage at the secondary winding 9 of an ignition coil 6 is insufficient to cause a spark, but the speed of the engine continued to be displayed on an indicating device 12. In a modification, when the maximum admissible speed is reached, a thyristor connected in parallel with the primary winding 5 is switched on to prevent the generation of sparks. <IMAGE>
