Title: Improvements in taping machines
IPC: B65B7/28
Filed: 1956-07-23
Abstract: 842,350. Applying adhesive tape to containers. COW & GATE Ltd., and CHARLES, G. K. June 27, 1957 [July 23, 1956], No. 22755/56. Class 73. Relates to a taping machine for applying adhesive tape to containers to seal the lids. Adhesive tape 32, Fig. 1, is fed from a spool 33 along a spring-urged pivoted guide arm 1 in the path of containers 35 which are rolled along a track 30 so that the tape initially adheres to the container, the guide arm being then pressed back by the advancing container to allow a spring- urged roller 40 to complete adhesion of the tape around the container, and the tape being drawn against and severed by a cutter 44. A second and similar taping device 50, 45, 40<SP>1</SP> is also provided and the two devices are linked by a connecting rod 22 in such a manner that when the first device 33, 1, 40 is operating correctly, the second device 50, 45, 40<SP>1</SP> is inoperative, and if the first device fails to effect correct adherence of tape to a container, the second device is automatically brought into action. The guide arm 1 has at one end a plate 2 with a boss 3, Fig. 5, mounted to pivot freely on a pin 4 on the machine frame and a tape feed pulley 6 is freely mounted on the boss 3. A friction washer 7 and a plate 8 are interposed between the pulley 6 and plate 2, the plate 8 having a finger 14, Fig. 1, adapted to engage with one arm 11 of a spring-urged bell crank pivoted on the plate 2 and having a trigger arm 12. As long as satisfactory initial adhesion of the tape to each container is effected, the tape is under sufficient tension to rotate the pulley 6 which by means of the friction washer 7 moves the plate 8 and its finger 14. The finger 14 moves the arm 11 until it is arrested by a stop pin on the plate 2 and when set in this position, the trigger arm 12 will be swung by the plate 2, during rearward movement of the arm 1, in a path clear of a pin 17 on a latch plate 16 on the pivot pin 4. Thus the pin 17 is not moved to engage in a recess A on a latch 18 pivoted at 19 on a bar 20 which is pivoted to the latch plate 16 and secured to the connecting rod 22. If however because of incorrect adhesion &c., the tape becomes slack and fails to rotate the pulley 6 and hence the plate 8 with its finger 14, the trigger arm 12 engages the latch pin 17 and raises it into the recess A of the latch 18. This causes a thrust on to bar 20 so that the connecting rod 22 is moved to release a retaining lever 52 thus permitting the second tape guide arm 45 to be moved into its operative position by its spring. At the same time the retaining lever 52 operates a micro-switch to close a circuit containing a red lamp or bell to indicate that the first taping device needs attention. When working correctly again movement of the trigger arm 12 brings it into engagement with a pin B on the latch 18 to unlatch the pin 17 from the latch 18. Thus the parts resume the position shown in Fig. 1, and the retaining lever 52 is moved to effect movement of the tape guide arm 45 to its inoperative position. Specification 574,156 is referred to.

Title: Improvements in or relating to benzene purification from mixed feed stocks
IPC: C07C7/08
Filed: 1954-08-05
Abstract: Toluene or benzene is purified by preferential solvent extraction from an impure fraction containing tuluene and benzene and containing also saturated hydrocarbons with boiling points close to that of the aromatic hydrocarbon, <PICT:0766276/IV(b)/1> by adding to such a fraction a sufficient quantity of olefins having a boiling point up to 10 DEG  C. higher than the saturated hydrocarbons to leave in the preferential solvent 2-8 per cent by weight of the olefins with the aromatic hydrocarbon extracted.  In a preferred method of operation the benzene and toluene stock containing the saturated hydrocarbons is fed to a fractionating column 2, equipped with a reboiler 3 and a reflux condenser 4, the benzene cut is removed through a line 6 and is mixed with a benzene cut from cracked stock which contains mainly olefinic impurities which has been similarly treated in a column 9. The combined feeds then pass into an extractive distillation column 16 in which it is treated with phenol, furfural or ethylene glycol introduced through a line 17, the extracted benzene is withdrawn via a line 23 to a stripping column 24 from which the benzene olefin distillate is withdrawn by a line 37 through a cooler to a mixer 39 to which sulphuric acid is supplied by line 40.  After removal of much of the acid in the settler tank 41, the benzene is decanted and mixed with caustic soda in a tank 45.  The benzene is finally separated through the reflux condenser line 54 from a finishing fractionator 48.  The product may exceed 99.95 per cent benzene.

Title: Improvements in life-guards or obstruction removers for road and other vehicles
IPC: B60R21/34
Filed: 1933-09-16
Abstract: 425,759. Friction clutches. SAFETY BUMPERS, Ltd., and CLIFFORD, V. J., 15, Princes Row, Buckingham Palace Road, London. Sept. 16, 1933, No. 22913. [Class 80 (ii)] [See also Group XXXII] A vehicle lifeguard comprises a rotatable roller mounted in front of the vehicle and connected with the wheels, or driving mechanism of the vehicle through an electromagnetic friction clutch. A governor may be incorporated in the clutch in order to prevent excessive rotation of the roller at high vehicle speeds. The roller is connected by a flexible shaft to the driven shaft 21 of the clutch, the tubular driving-shaft 25 of which is driven from the vehicle gear-box. The shaft 25 carries a cup-shaped driving member 28 having inwardly-projecting flanges 29, 30, 31 adapted to co-operate with magnetic friction clutchplates 37, 38, 39 separated slightly from one another and slidably mounted on the splined end 36 of a tube 34 connected by a spring 35 to the driven shaft 21. Coils 33, 41 surround flanges 32, 40 formed on the cup-member 28 and clutch-plate 37 respectively. Fig. 3 shows the electric controlling circuit in which a battery 52 for energizing the coils 33, 41 is controlled by switches 53, 54, a relay 55, and a resetting, spring-influenced, push-button switch 56. In operation, when either switch 53 or 54 is operated, e.g. on striking an obstacle, the coils 33, 41 are energized and the clutch plates 37, 38, 39 are drawn into contact with the rotating flanges 29, 30, 31 thus rotating the tube 34 which transmits the drive to the roller through the spring 35. The relay 55 short-circuits the switches 53, 54 so that the clutch remains engaged until the resetting switch 56 is operated, causing reversal of current through the coil 41 and a repelling action between the clutch plates and flanges. The governor comprises weighted arms 44, 45 pivoted about a diametral axis 46 and carrying transverse members 50, 51, which, when a certain speed is exceeded, bear axially on the clutch plate 37 so as first to disengage the plate 37 forcibly from the flange 29 and then, if the speed is sufficiently great, the plates 38, 39 in turn from the flanges 30, 31 thus reducing the speed.

Title: Improvements in and relating to the production of tubular articles, such as tubular metal rivets
IPC: B21K1/58
Filed: 1947-08-18
Abstract: 634,530. Forging rivets &c. LINREAD, Ltd., and LYNALL, E. H. Aug. 18, 1947, No. 22932. [Class 83 (iv)] Dies.-In a method of cold forging a tubular article such as a flanged head tubular rivet having a shank with a non-uniform bore from a tubular blank with a uniform bore, pressure is applied longitudinally of said blank by a punch to cause internal upsetting of the blank on to a stepped mandrel carried by the punch, the blank being confined within a die cavity and the head flange being shaped by a die cavity in the punch. The blank 1 is preformed by a punch 6 having a tapered portion 5 and a flange forming die cavity 7, Fig. 2. An ejector 4 is then adjusted to lift the flange 1a above the die cavity 2, Fig. 6 (not shown), and the finishing operation is performed by a punch assembly, Fig. 5, comprising a hollow body portion 8 screwed to a base 13, a slidably mounted ram 11 having a sleeve-like forward end 10 and normally projected forward by a spring 19, and a mandrel 16 having a screwed connection with the base 13. In operation, as the member 13 descends, the spring-loaded ram 11, presses the blank hard down on the ejector 4 and thereafter is forced back until it abuts the base 13. The mandrel 16 meanwhile enters the bore of the blank and during the final stage when the body 8 engages the die 3 the metal of the blank is upset inwardly around the pilot portion 18 of the mandrel 16, Fig. 8. By adjusting the body 8 and mandrel 16 in relation to the base 13 the amount of retreat A of the ram 11 within the body 8 may be varied to forge flanges of different thicknesses. The smaller diameter portion of the bore of the rivet is subsequently tapped.

Title: Wrapping rod-like smoking articles
IPC: A24C1/30
Filed: 1971-09-16
Abstract: 1370880 Wrapping cigars MOLINS Ltd 16 Sept 1971 [17 Sept 1970] 22974/74 Divided out of 1370878 Heading A2C Cigars are made by rolling a smokable rod, e.g. a rod wrapped in a longitudinal wrapper as produced by a continuous rod machine, between a plate and a co-operating roller drum together with a strip of sheet wrapper material, e.g. of reconstituted tobacco, applied initially at an inclination to the rod so that the strip is wound into a helix with overlapping turns. The strip is wound from the lit end towards the mouth end and is secured to the rod by glue only at positions close to the, ends of the cigar, or it may be secured at one end only. As shown, two wrapper strips 8 striped with glue at 18 are wound around a doublelength rod 22, and tapered mouth portions are formed, between lines 24 and the mid point at which the rod is subsequently to be severed, by raised portions on the plate and roller drum. To facilitate the reduction in diameter the middle section of the rod may be less densely packed with tobacco, and the ends of the longitudinal wrapper material may be slit. Cigars may be made singly instead of in double lengths as described above. Apparatus for cutting strips of sheet material and winding them around tobacco rods is similar to that described in Specification 1370878.

Title: Improvements relating to the production of oil gas
Inventor: HAWES JACK MALCOLM
IPC: F02B43/08
Filed: 1950-09-19
Abstract: 685,796. Generating oil gas. HUMPHREYS & GLASGOW, Ltd. Sept. 19, 1951 [Sept. 19, 1950], No. 22976/50. Class 55 (ii). In a cyclic reversible flow process of oil gas manufacture, each cycle comprises a heating phase wherein carbon deposited in the plant is burnt off in air and a gas-making phase wherein oil is gasified in steam and the gases modified catalytically, the direction of flow of the air and steam in each cycle being the reverse of that in the preceding cycle. In the form shown, the apparatus consists of two halves A and B each comprising a carburetter 1a, 1b, a temperatureadjusting regenerator 7a, 7b, a catalyst chamber 2a, 2b and a heat regenerative section 3a, 3b. The carburetters 1a and 1b are connected by a duct 6 whilst the regenerators 3a and 3b are connected through a valve 5 to a gas washer 5x. The plant is brought to gas-making temperature by admitting heating oil or tar and air to the carburetters and catalyst chambers through lines 13a, 13b, 15a, 15b, 17a, 17b and 18a, 18b, the combustion products discharging through stack connections 4a, 4b. Steam is then admitted through valve 11b and is superheated in the right-hand half B of the plant, passing through duct 6 into carburetter 1a where it meets a spray of heavy gas-making oil from line 16a. The oil is gasified and partially cracked, the gases passing wholly or in part through the regenerator 7a or through line 8a into the chamber 2a where they are brought into contact with a catalyst, for example, a nickel or iron compound supported on a refractory carrier such as alumina, the extent of this treatment being controlled by diverting the volume of gas which does not require the treatment through the by-pass 9a directly to the regenerator 3a. The gas from chamber 2a may by-pass the regenerator through line 10a, the streams then uniting and passing through valve 5 to the washer 5x. Additional steam may be admitted as required through pipes 14a, 19a and 20a. At the end of the run, the plant is reheated to gas making temperature by blowing air from pipe 11a through the plant in the opposite direction, the air burning off the deposited carbon. Heating oil or tar is also injected as required, the hot gases discharging through line 4b. The next gas-making phase is then started by passing steam from line 12a through the half A of the plant and gasifying the oil in the half B.

Title: Improvements in disc brakes
Inventor: DAVIS JOHN WALTER
IPC: F16D55/224
Filed: 1961-06-27
Abstract: 1,001,514. Disc brakes. DUNLOP RUBBER CO. Ltd. June 8, 1962 [June 27, 1961], No. 23137/61. Heading F2E. A disc brake comprises a rotatable disc 10, a friction element 27, a deformable element 32 to maintain the element parallel to the braking surface of the disc and a brake-applying member 11, 12 independent of the deformable element for forcing the element into frictional contact with the disc and for taking the torque when the brake is applied. As shown, friction elements 27 are secured to blocks 26 loosely mounted in apertures 24 in the pressure plates 11, 12 which are pivoted at 13 on the fixed support 14. Bolts 30 are threaded into the blocks 26 and are gripped by hooks 33 at the end of the deformable metal beams 32. Operation of the brake is effected by a lever 20 pivoted at 21 on the plate 12. A tie-rod 15 connects the plate 11 to a lever 20 by means of a trunnion block 18 and a nut 19 which may be rotated automatically as wear takes place. If the friction pads 28 which are bonded to metal backing plates 29 are not in full contact on initial application of the brake, the backing plates 29 rock on the convex surface of the plates 11, 12 to accommodate themselves to the disc. The shank of the bolt 30 moves along the hook 33 which grips the shank when the brake is released to retain it in the aligned position. As wear takes place the beams 32 will take on a permanent set but will still retain the bolt 30 in the aligned position and will have enough resilience to withdraw the pads after each brake application.

Title: Improvements in or relating to radar systems
IPC: G01S13/87
Filed: 1954-08-10
Abstract: 750,276. Radar. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. Aug. 10, 1954 [Aug. 14, 1953], No. 23184/54. Class 40 (7). A pulse radar system capable of identifying a particular target includes at the target, means for deriving the pulse modulation from the received radar transmitter and for using it to modulate a reply transmitter and, at the radar, means for receiving the reply signals and using them in addition to the normal echo signals to provide a display on which the target can be identified. In a simple embodiment (Fig. 1, not shown), the normal echoes are used to give a P.P.I. type display and the reply signals, after compensation for any delay at the target and separate receiver at the radar, are applied to the same display to intensify the indication of the target. Alternatively, the reply signal may be used to vary the indicator tube focusing at the time of display of the corresponding echo signal or to produce a double dot indication ; it can also be displayed by itself on a separate display tube. In a second embodiment the reply signals received at E2 (which receiver may also form part of a communication link and is provided with a loud-speaker L for that purpose) are demodulated and fed to phase bridge P.B. The radar modulation signal is fed through phase compensator L.Z.G. and phase adjuster P.S. to a second input of bridge P. B. When the two inputs to the bridge coincide the local signal form P.S. is passed to unit I.G. which produces the distinguishing mark signal for application to the display tube S.A. Manual adjustment of the phase shifter P.S. to obtain coincidence may be facilitated by the provision of a visual indicator P.I., or a phase discriminator arrangement may be used to adjust unit P.S. automatically for coincidence. It may be arranged that the target transmitter can be switched on and off from the radar station. If it is required to identify more than one target each may have its own reply frequency and a display tube IT be provided fed from a frequency sweep receiver W.A. to indicate the frequency of each of the signals received. Receiver E2 may be adjusted to feed an identifying signal corresponding to one of these to the main display S.A.
