Title: Method and apparatus for carrying out gas phase reactions in the presence of a solid particulate catalyst and for continuously regenerating the catalyst so that the regeneration and reaction steps are isolated from each other
IPC: B01J8/40
Filed: 1974-11-28
Abstract: 1487336 Catalyst regeneration in I.C. exhaust treatment A M SOLDATE 28 Nov 1974 [30 Nov 1973] 51525/74 Heading B1F An apparatus for carrying out gas phase reactions in the presence of fluidised particulate catalvst, e.g. the treatment of I.C. engine exhaust gases, and for simultaneously withdrawing catalyst, regenerating it and returning it to the reaction zone comprises a closed circuit containing an elongated reaction chamber 41 having a spaced apart inlet 41b and outlet 41a; an elongated regeneration chamber 46 having a spaced apart inlet and outlet; a tubular feed conduit 48 connecting the reactor outlet and regenerator inlet; a tubular return conduit 50 connecting the regenerator outlet and reactor inlet; inlet and outlet means 54, 58 for passing a stream of reactant gas through the reaction chamber in countercurrent flow to fluidised catalyst; means for regenerating spent catalyst in the regeneration chamber; and means for vibrating the closed circuit to force circulation of the catalyst in a fluidised manner, preferably horizontally, around the closed circuit in such a manner that conduits 48 and 50 are maintained in a filled condition to prevent interaction between reactions taking place in the reaction zone and the regeneration zone. The apparatus may be vibrated by suspending it by three coil springs 214 from fixed brackets 44 and engaging it with a rotating shaft 228 carrying counterweights 218 and 220 at its upper and lower ends. By varying the radial angle between the two weights, the speed of rotation and relative mass of the counterweights the direction of flow form of motion applied to the catalyst particles may be controlled. The shaft 228 is connected to the drive means 224 by a flexible connection to avoid transfer of vibration to the drive means. The catalyst may be regenerated by counterflow contact with regeneration gas, e.g. air to burn off carbon, introduced through lines 46a and 46b. The regenerator may contain an electrically-heated tubular furnace 60 to heat the catalyst. A pair of separate catalyst regeneration chambers may be used, the catalyst being heated in one regeneration circuit and cooled in the next. One method of regeneration involves impingement of spent catalyst particles with the heated wall of a chamber formed of the same material as the catalyst with resultant deposition of a fresh surface layer on the catalyst particles. The gas outlet 58 from the reaction chamber may include a cyclone 64 to separate any catalyst particles thus carried out of the chamber and a return pipe 71 for separated catalyst.

Filed: 1969-10-31
Abstract: 1284894 Gas filter cleaning LUGAR GES FUR ENTSTAUBUNGSTECHNIK mbH 31 Oct 1969 53397/69 Heading BIT The hollow fabric filter elements in each chamber of a housing are cleaned by first simultaneously closing an outlet valve leading to a suction source and opening a second valve to connect the chamber in question to a reciprocating valve, which repeatedly connects the downstream side of the chamber to the suction source and to a supply of reverse flow gas. Additional valves, pressure or times are so arranged that each reciprocation of the valve first allows the dirty gas pressure to deflate the elements but without any filtration occuring, then reverse flow gas inflates the elements and continues to flow for a short time after they are fully inflated. The outlet and second valves of the different chambers are operated in sequence by a common motor, while a second motor operates the reciprocating valve, which serves all the chambers. The lower ends of the chambers open into a common dust hopper with a discharge worm. The dust content of incoming gas or the permeability loss of the elements may be monitored by a device which controls the multivalve motor to vary the duration of cleaning periods.

Abstract: 1,240,474. Ornamental articles. W. J. A. KEMPSTON. 14 Nov., 1968 [23 Nov., 1967], No. 53432/67. Heading B6G. [Also in Divisions El, F4 and G5] A decorative, three-dimensional hollow device is made from a plurality of units, each unit formed from a generally planar blank which blank has a front surface and a rear surface and bears crease-lines defining lines of weakening which form hinges, the crease-lines defining a central main panel and outer wings hinged thereto, at least four units being held together by removable means to form the device with either the front surfaces of adjacent wings abutting or the rear surfaces of adjacent wings abutting. As shown in Fig. 4, a disc provided with crease lines 2 bounding a central equilateral triangle 3 and arcuate shaped wings 4 extending from the edges of the triangle with a trough-shaped notch 7 cut out at each apex of the equilateral triangle 3. To form a device, the wings of the unit are bent at an angle to the central portions 3 and each wing of one unit is joined to a wing of an adjacent unit by means of an elastic band 9 running between the corners 8 of the notches 7, and lying along the crease line 2. Spherical, pyramidal or cylindrical devices can be formed. In Fig. 5 (not shown), six units of Fig. 4 are joined in a ring and.three of these rings are then joined one on top of the other to form a cylinder. The devices can be suspended by nylon or other cord to form decorations or can be made into lamp shades. The device is suspended by its apex or by a top unit which is provided with a slit from a hole at the centre of the unit to the middle of one wing edge. A plastics nut on which the lampshade can rest can be attached to the suspending cord, thus holding the walls away from the light bulb. In a further modification, the units are joined by an extra piece of board. The flaps 4 are provided with two slots cut into the edge of the flap, the slots extending half way into the flap. The extra piece of board has corresponding cuts so that when pushed together a male and female lock is achieved. This modification enables re-use of the units for educational play. In another modification, the units can be made of a thicker material to make knock-down huts wherein the projecting flaps on the units are joined with clips, e.g. sliding plastics clips. Alternatively, the projecting flaps may be joined with pillar screws.

Patent GB-558415-A (GB)
Abstract: 558,415. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 21, 1942, No. 18112. Convention date, Dec. 30, 1941. [Class 38 (v)] Bimetallic switch for starting discharge lamps is arranged so that after a number of failures to start, no further attempts occur until the circuit is opened. Two bimetal strips 20. 26 are mounted so that their planes of bending are at right angles. One, 20 is looped in the form of an inverted J and is secured to terminal plate 14. The other, 26 is secured to terminal plate 16. The lamp electrode heating circuit is connected to terminal plates 13, 14. A low resistance heater 29 connects plate 13 and strip 26, while a high resistance heater 22 connects plate 13 and strip 20. A U-shaped contact extends from the end of strip 26 and a bar contact 21 from the looped end of strip 20. Initially bar 21 bears against the inside of pin 27 of the U-contact through the springiness of the materials. On switching on strip 26 bends and pin 27 slides along and finally snaps away from the end of bar 21, thereby opening the circuit to give the starting current-surge. The shunt 29 being removed, heater 22 warms strip 20 up to cause bar 21 to take position opposite the space between pins 27, 28, as shown, without making contact, if the lamp starts. If it fails, continued heating from heater 22 moves bar 21 against the inside of pin 28. Again strip 26 flexes and pin 28 slips off the end of the bar to break the circuit to heater 29. If still the lamp fails, strip 26 returns to cause pin 28 to engage the end of bar 21, to initiate a further starting effort. If this fails, the continued heating of the strip 20 will move bar 21 out beyond the reach of pin 28 and this condition remains until the circuit is broken at the hand control. The use of the inverted J shape of strip 20 compensates for ambient temperature variations.

Title: Auxiliary drive endless loop tape cartridge
IPC: G11B23/06
Filed: 1970-11-25
Abstract: 1323580 Endless tape cassette D V MANN and H C MANN 25 Nov 1970 [26 Nov 1969] 55954/70 Heading G5R  In an endless tape cassette intended for use with a tape recorder designed to accept reel to reel cassettes, an auxiliary drive for the tape is provided which can assist the normal capstan drive in the play-back/record mode and provide a direct fast forward drive when the capstan and tape heads are removed from the tape during the fast forwarding mode. The drive is provided by hub 21 having a drive surface 23 of resilient material, which is coupled in use to the forward reel drive sprocket of the recorder. Idler wheel guides 20 mounted on a floating plate 15 are clustered about the hub 21 to urge tape 31 into contact with the drive surface. The tape platen and hub 43, 44 are mounted on a bearing sleeve 40 which does not engage the other recorder drive sprocket. The hub 44 is clutched to the sleeve 40 and the idler wheels 20 are clutched to their spindles 19 so that they rotate in one direction only. The idler wheels can be flanged or may be replaced by tape rub blocks. Near the hub 44 the tape platen 43 is provided with elastomer pads 47 which increase the friction between the platen and the edge of the 5-30 innermost tape turns, thus the drive to the platen is transmitted by these innermost turns B allowing the outermost turns A to form loosely on the platen. In the arrangement described with reference to Fig. 4 (not shown) the positions of the tape reel and the auxiliary drive hub are reversed, and a slipping drive to assist rotation of the tape platen is described with reference to Fig. 3 (not shown). Where alarge coil 31 of tape is used the angle of the tape as it runs from the edge of the coil to roller 50 is such that it increases the load on the tape platen. This is avoided in the Fig. 8 arrangement (not shown) in which initially the tape is passed to a roller on the other side of the cassette before being returned to the roller 50. The tape drive can be controlled via contact members 35 which co-operate with conducting patches on the tape. The signal is passed via contacts 38 to the recorder circuitry and where the cassette width is less than that of the recess provided in the recorder an insulating member, Fig. 5 (not shown) carrying a pair of contacts can be used to bridge the gap between the cassettes and recorder contacts.
