Title: Improvements in or relating to a process for the oxychlorination of olefins
IPC: C07C17/156
Filed: 1964-10-05
Abstract: An olefin is oxychlorinated by reacting a gaseous mixture of olefin, hydrogen chloride and oxygen or oxygen-containing gas in the presence of a fluidized catalyst which is cooled by indirect heat exchange with water passing through a cooling system, the amount of water being regulated in accordance with the catalyst temperature so that substantially the whole of the water is converted into steam, which is collected.  In an example 1,2-dichloroethane is obtained from ethylene.  The catalyst may be CuCl2 or other heavy metal chloride or alumina.ALSO:In a reactor for exothermic catalytic reactions (e.g. fluidized oxychlorination: see Division C2) the catalyst is cooled by indirect heat exchange with water passing through a cooling system, the amount of water being regulated in accordance with the temperature of the catalyst so that substantially the whole of the water is converted into steam, which may be collected and used e.g. for pre-heating the cooling water.

Filed: 1974-10-02
Abstract: 1518674 Delivering sheets METAL BOX Ltd 25 Sept 1975 [2 Oct 1974] 42712/74 Heading B8R A conveyer system. e.g. for meat slices 5, Fig. 2, comprises a pair of belts 2 passing over pulleys 6, 8, 10, 12, 14, 16 and a pair of belts 4 passing over pulleys 16, 18, the pulleys 6, 16 being mounted on a common shaft 20 and the pulleys 6, 16, 8, 18 being carried on a carriage 26 reciprocable by an hydraulic cylinder. The pulleys 16, 18 are attached to the shafts 20, 24 through one-way clutches. The belts 2 are driven by a motor through the pulley 10, and the belts 4 are normally driven by the belts 2. Meat slices 5 initially fall on to the belts 4 at the point A to form a shingled stream. When a predetermined number of slices have fallen, a monitor actuates the cylinder to move the carriage in the direction B, accelerating to a speed greater than that of the belts 2. Until the carriage reaches the speed of the belts 2, the belts 4 continue to move at the speed of the belts 2 by slippage of the clutches on the shaft 20. When the carriage speed exceeds the belt speed, the clutches on the shaft 24 lock and the bolts 4 move at the speed of the carriage, creating a gap in the stream of slices 5 to form a batch, while the pulleys 6, 16 move to the right of the point A so that subsequent slices fall on to the belts 2. To delay the deposition of the first slice of a new batch, the assembly is pivoted by an hydraulic actuator 41 away from the slicing-machine 3. The carriage 26 is then retracted and the assembly raised, the belts 4 thereby being moved from under the slices to allow the batch to fall on to a weigher. In another form, Fig. 4, a shingled stream of bacon rashers is fed on to the left end of the belts 2, formed into shingled batches, and delivered on to an intermittently moving conveyer 32. The shaft 46 of the roller 48 of the conveyer 32 carries a pulley 34 supporting a belt 36 passing over pulleys 34, 38, 40, 44, 42, the pulleys 44 being attached to the shaft 24 through a one-way clutch, the pulleys 40, 44, 42 being mounted on the carriage 26. When the carriage reaches its right-hand position 18A, the conveyer 32 is driven by a motor at a speed greater than that of the belts 2, causing the belts 4 to be driven at the higher speed for transfer of a batch to the conveyer 32.

Abstract: 919,104. Closed liquid coolant circulation systems; surface condensers. ANDERSSON, B. G. Nov. 30, 1961, No. 42861/61. Class 64 (3). A condenser 10 in a closed liquid coolant circulation system has cooling water sprinkled on it from a supply pipe 15, the water then being collected in a container 17 below the condenser, and flowing out of the container 17 through a conduit 18 and non-return valves 19 which communicate with the lower part of a pressure chamber 7 situated below container 17, the pressure chamber also communicating with the pressure side of an aircompressor 13 and being further provided in its top with an air outlet 20 controlled by a valve 21 which is governed by a float 22 disposed in the pressure chamber. As shown, water sprinkled from a sprinkler 16 on to condenser 10 is caught in a collector plate 26 and aerated for cooling purposes by compressed air from compressor 13 via conduit 29. The water is also cooled by air sucked by a fan 8 through openings 11. The water then overspills into container 17. Meanwhile the water level in pressure chamber 7 has been dropping until a position of the float 22 is reached at which the valve 21 is opened and pressure is released in the pressure chamber 7. This will allow the valves 19 to open and the collected water in chamber 17 will flow down conduit 18 into the pressure chamber; the water level will then rise until the float 22 reaches a position which will close the valve 21. Hence pressure will build up and the cycle will be repeated.

Controlled rectifiers are each provided with two finned heat sinks serving as electrode connections and are slid one above the other into the side of a space between two parallel walls 7, 8 so that each heat sink defines a cooling duct with its adjacent wall. Insulating bars 17, 27, 37 separate the rectifiers vertically and prevent cooling air from entering the spaces between the two heat sinks of each rectifier where it would set up unwanted vibration in the control leads. The bars are attached to the walls by members 18, 19, &c. which prevent air from leaking from the duct between vertically adjacent rectifiers, the corresponding heat sinks of which form continuous ducts. An embodiment is described in which rectifiers are slid into the space between the walls one from each side (at each level). A cylindrical pillar (50) runs parallel to the ducts and laterally seals the air spaces between the heat sinks of each rectifier from the vertical ducts formed between laterally adjacent rectifiers. The assembly has a third wall parallel to the other two to define a further space into which rectifiers are fitted.

IPC: C06F1/26
Abstract: 435,966. Cutting match-cards. SAFEWAY MATCHES, Ltd., 19, Bligh Street, Sydney, Australia,.-(Assignees of Newman, J. G. ; 54, Darlinghurst Road, Kings Cross, near Sydney, Australia) Dec. 3, 1934, No. 34719. Convention date, Dec. 20, 1933. [Class 145 (i)] [See also Group XII] Blanks for match books made from a wood ribbon with a crosswise grain and a reinforcing paper strip cemented lengthwise along one edge, are cut in a machine in which the ribbon moves forward in splint - width steps and is slit by a guillotine consisting of a rapidly oscillating paper-thin knife blade coacting with a hard metal anvil seated on a flexible rubber cushion, alternate splints then being offset to stagger the splint points. After passing under a circular saw to form a kerf near the paper strip to facilitate detachment of the splints the ribbon is moved step by step under a knife carrier 185 by a member 51 to which a to- and-fro movement is imparted by means of an eccentric 11 on the main shaft 10, a yoke stem 25, crank arms 121, 122, and a shaft 120. The yoke stem throw is regulatable by varying the position of its fulcrum pin 14 which is supported by a crank arm 16 keyed to a shaft 17 carried by a bell-crank lever 18 set in position by a vertically sliding member 23. The oncoming ribbon is kept in contact with an adjustable fence 63 by a grooved jockey wheel 64 spring-pressed against the ribbon's outer edge. The feed member 51 carries a series of pins 53 engaging the ribbon and registering with a slot 161 in the machine table and a slot 54 in a presser foot 55 on a plunger 57 which is pressed by a spring 58 on to the ribbon. To cause the pins to bite into the ribbon the member 51 is caused to rise during the forward and fall during the backward stroke by means of an eccentric 40, a rod 42, arms 44, 46, and a rock shaft 45. The knife blade 80 in a clasp holder 185 impacts with a hard metal anvil 81 seated on a rubber cushion 82 the ribbon being guided thereover by a slotted shoe 83. The knife holder is carried on a plunger 87 which is reciprocated by an eccentric strap 99. To effect the offsetting of alternate splints a push rod 111 ascends through a slot 112 immediately after each alternate slitting movement of the knife, this rod being actuated by means of a striker cam 104 coacting with a rod 106 articulated to a lever 109 carrying the push rod. Alternatively the lever 109 may be rocked by a striker which is depressed by tappets on a cam fixed to a detent wheel receiving an intermittent motion by a pawl mounted on a crank lever linked to the knife carrier. The ribbon passes under a levelling shoe which renders uniform the degree of offsetting. A modified ribbon feeding mechanism comprises a spiked wheel geared to a detent wheel operated by a pawl. Acute chisel points are formed on the splints by grinding or milling each flat to limit the thickness of the heads.

[Also in Division G3] A method for quantative analysis of a known constituent ionized in solution comprises measuring the conductivity of the solution, adding excess buffering agent reacting with the constituent and again measuring the conductivity. The amount of the constituent is then determined from a curve of differential conductivity versus concentration, previously prepared from measurements with known concentrations. In an industrial process the differential conductivity signal may be used for controlling the addition of the constituent to the solution. Several examples are given of determining:- (i) alkalinity of boiler feedwater or effluent from lime-soda water softeners or the concentration of alkali in a sulphate digester for paper processing by neutralizing with CO 2  or (ii) the concentration of sulphuric acid when neutralized by excess ammonia, hydrazine, cyclohexylanine or morpholine. Fig. 1 (not shown) illustrates the application to automatic control of the addition of sodium hydroxide to boiler feedwater. Samples of the boiler water have their conductivity measured in cells (6), (12) before and after CO 2  is introduced in neutralizing chamber (8). The cells are connected in bridge circuits and the output signals connected to a "computor" controlling the hydroxide feed.
