IPC: C07C45/71
Filed: 1967-09-25
Abstract: 1,170,825. Reactions of organometallic compounds with unsaturated organic compounds. HERCULES Inc. 25 Sept., 1967, No. 43599/67. Heading C2C. [Also in Division C5] Organic compounds are obtained by reacting an ethylenically unsaturated compound of formula in which R 1 , R 2 , R 3  and R 4  are hydrogen or hydrocarbon radicals having 1-30 carbon atoms, thienyl or furyl radicals which may be substituted by 1-3 of the following non- hydrocarbon groups: -OH, halogen, -OR<SP>6</SP>, -OCOR<SP>6</SP>, -NO, -CHO, -COOR<SP>6</SP>, -NR<SP>5</SP> 2 , -CONR<SP>5</SP> 2 , -CN, -SO 2 R<SP>6</SP>, -COOH, -COO Metal or -COR<SP>6</SP>, in which R<SP>5</SP> represents a C 2 -C 12  hydrocarbon group free of ethylenic or acetylenic unsaturation and R<SP>6</SP> represents R<SP>5</SP>, CH 3  or a non-hydrocarbon group as specified above except for -OH, with an organometallic compound of the platinum or palladium sub-groups of Group VIII in which the organic group of the organo metallic compound is a saturated carboalkoxy group containing 1-4 carbon atoms in the alkoxy group or a saturated C 1 -C 20  hydrocarbon group, at least one of which carbons is attached to the metal and is not attached to a carbon atom carrying hydrogen and optionally carrying 1-5 substituents from the following: C 1 -C 4  alkyl, C 1 -C 4  alkoxy, -CHO, -COOH, -COOalkyl (C 1 -C 4 ), -CO-, -Cl, -NO 2 , -NHCOCH 3 , N(C 2 H 5 ) 2  or a thienyl, furyl, benzothienyl or benzofuryl group. The organometallic compound of the Group VIII metal may be produced in situ for an organometallic compound of a metal of Group II B , III A  or IV A  of the Periodic System, preferably of mercury and a salt of the Group VIII metal. The preferred organometallic compound used is one of formula QM<SP>1</SP>X in which X is a C 1 -C 4  carboalkoxy group, a C 1 -C 20  hydrocarbon group as defined above optionally carrying from 1 to 5 C 1 -C 4  alkyl, C 1 -C 4  alkoxy, -CHO, -COOH, -COO (C 1 -C 4  alkyl), -CO-, -Cl, -NO 2 , -NHCO CH 3  or -N(C 2 H 5 ) 2  groups or a thienyl, furyl, benzothienyl or benzofuryl group. It is desirable that a cupric salt should be added to the reaction mixture to act as a redox component in the regeneration of the Group VIII metal. The nature of the products depends on the groups present in the starting materials and more than one group in the olefinic starting material may react. Numerous examples of the process are given and among the products are unsaturated aldehydes, alcohols, ketones, esters, ethers, nitriles, halides and also carboxylic esters which may carry ketone, aldehyde, hydroxy, amine, cyanide, amide or nitro groups and saturated halohydrocarbons, aldehydes, ketenes, carboxylic acids, ketones, nitro compounds and esters.

Title: Fluid operated impact device
IPC: B25D9/14
Filed: 1973-09-18
Abstract: 1382950 Percussive tools CONSTRUCTION TECHNOLOGY Inc 18 Sept 1973 [18 Sept 1972 25 Sept 1972] 43686/73 Heading B4C An hydraulically operated impact device for applying repetitive impact forces to a tool 20 comprises a hammer 28 carrying a piston 70, an energy storage device 45, first and second chambers 90, 60 on opposite sides of the piston and a valve sleeve 75 movable to a rearward first position when the fluid pressure is to move the hammer rearwardly against the energy storage device and movable forwardly away from the piston to place the first and second chambers in fluid communication with each other to permit the energy storage device to drive the hammer forwardly. As shown, the hammer 28 is secured to a bearing plate of the energy storage device which may be a compression spring or an air spring chamber 42, the hammer being arranged to pass through a cushion plate 30 and deliver blows on the tool 20 through an anvil 120. The valve sleeve 75 has radial notches 87 on its rear end face and operates as a differential piston between abutments 55 and 65 by having a larger area at its rear end operating in a bore 52 which is larger than the bore 53. A safety device in the form of a valve sleeve 100 prevents operation until the tool is pressed against a work surface. In the inactive position shown in Fig. 4, a groove 105 in the sleeve 100 communicates a port 106 with a port 112 to allow the fluid pressure supply to the inlet port 91 to be by-passed through a line 107 to a reservoir 63. When the force applied to the tool 10 and anvil 120 overcomes the differential hydraulic bias caused by the larger end area 115 of the groove, the sleeve moves back to close port 112. The build up of fluid pressure in the chamber 90 first causes the valve sleeve 75 to move into engagement with the abutment 55 to close exhaust port 79 and then causes the piston 70 to move the hammer 28 rearwardly to compress the air spring 42. When in the fully retracted position, Fig. 6 (not shown), the piston 70 is in engagement with the abutment 55 to allow the pressure fluid in the chamber 90 to pass through the radial notches 87 and cause the valve sleeve to move forwardly into engagement with the abutment 65. With the valve sleeve now in its forward position the chamber 90 is open to communication with the chamber 60 and the exhaust port 79. The energy stored in the air spring 45 is then able to drive the hammer 28 forwardly, Fig. 7 (not shown). The hammer impacts the anvil 120 just before the rear end of the hammer engages the cushion plate 30. So long as the device is pressed against a work surface, the hammer will cycle at a rate determined by the flow rate of the pressure fluid. In an alternative embodiment, Figs. 8 and 9 (not shown), the rearward force of the hammer for compressing the air spring is increased by adding the area of the valve sleeve (80<SP>1</SP>) to the area of the piston (70<SP>1</SP>), the valve sleeve becoming part of the piston during the rearward movement under fluid pressure.

Title: Closure for a bag having a flat mouth and apparatus for the manufacture thereof
IPC: B65B9/20
Filed: 1964-10-29
Abstract: 1,080,377. Forming the top closure of a filled bag. E. BOK. Oct. 29, 1964 [Oct. 31, 1963; March 9, 1964], No. 44117/64. Heading B5D. [Also in Division B8] A strip of adhesive tape 6 (Fig. 2) is attached to the inside of a second piece of adhesive tape 18, 19 and the two strips folded around tear means 7 before being applied to the mouth of an already sealed bag. Flaps 12, 13 enable the adhesive strip 6 to be removed from the bag when both strips of adhesive have been broken at 17, 20 by the tear string 7. The outer strip of adhesive tape preferably extends beyond the edge of the bag and is slit and perforated to facilitate opening the bag. Forming the closure.-The edges of a strip of adhesive tape 84 (Fig. 16, not shown), 6 (Fig. 2) are folded inwards by guide plates (171, 172, 173, Fig. 16) and the tape then severed at and pressed by an air stream against a second strip of adhesive tape (48, Fig. 10, not shown), 5 (Fig. 2). Both strips of adhesive tape are then folded about a tear string (53) and drawn by jaws (106, 107, Fig. 12, not shown) across the mouth of a bag held in laterally movable jaws (102, 104) so that the closed bag of Fig. 2 is formed. The mouth of the bag has previously been sealed after filling (66, 67, Fig. 4, not shown) and weakly sealed (65), by jaws (68, 69, Fig. 5, not shown) whilst the bag is held by a clamp. The bags may then be fed on a conveyer belt to a resilient trough which rotates under the weight of a filled bag to drop it on to a conveyer belt by which it is conveyed with the weakly sealed end leading to the jaws of a clamping device. The applying of the adhesive tape closure to the filled bag is initiated by an electric impulse when the bag touches the top of a stop pin (146, Fig. 7, not shown). Alternatively, the bag may be fed from the filling device down an inclined shoot (70, Fig. 9, not shown) towards a plunger (74) which, controlled by an electric impulse, swings a bag by pusher members (72, 73) past an electric relay (83) controlling the feed of the adhesive strip to a closure table (42). In another embodiment the bag is held against a flap (232, Fig. 22, not shown) by suction blocks (235, 236) as the flap is rotated about a horizontal axis (233). The bag is then conveyed to the closure device and the flap (323) returns to its original position. A feeler arm resting on the adhesive tape (48) operates a switch to stop the machine when no tape is fed past it.

Abstract: 1474469 Ultrasonic leak-detector  COMMISSARIAT A L'ENERGIE ATOMIQUE 16 Oct 1974 [18 Oct 1973] 44925/74 Heading G1G The presence of gas bubbles in a liquid, indicative of a leak e.g. the coolant system of a nuclear reactor or blast furance tuyere, is detected by transmitting at least one ultrasonic wave-train through the liquid from a transducer towards a reflector, sensing the series of echoes arising because of multiple reflection of the or each wavetrain, counting these echoes, and deriving a signal porportional to the total count and hence dependent on bubble presence. Fig. 1 shows a transmit-receive transducer 10 and reflector 16 installed on a piping system 2. A circuit Fig. 3 (not shown) is arranged to (a) key on oscillator (32) to drive transducer 10, (b) amplifying (40) and shape (42) echosignals into spikes, (c) select (44) the spikes corresponding to echoes from reflector 16 and further shape them for driving a counter (46) and, (d) temporarily store (54) the count then converts it (56) to an analogue voltage for application to a recorder. The count is also displayed digitally. A meter across the transducer issued to monitor the oscillator operation. The presence of gas bubbles causes increased attenuation of the ultrasonic energy, hence a reduction in the number of detectable multiplereflection echoes, compared to the normal no-bubble situation. The apparatus may be calibrated by introducing controlled quantities of gas into the liquid. The use of several transducer/ reflector units at different locations on a structure being tested for leaks enables the leak position to be found. A common circuit may be shared by the several units.
