Abstract: 1299487 Shrink-wrapping ELEKTRISKA SVETSNINGS AB 8 June 1970 [10 June 1969] 27637/70 Heading B8C A tubular sheath of heat shrinkable plastics is placed around a prismatic article so as to project beyond the ends of the article by an amount such that, on shrinking, the projecting portions from a plane surface having a central orifice, a piece of non-heat shrinkable plastics is applied to each end of the article, the sheath is heat shunk, and the sheath is sealed to the underlying non-heat-shrinkable plastics. The sheath may be applied before, after, or simultaneously with, the application of the non-shrinkable plastic. Articles 1 are fed by a rollerway to a lifter 3 which lifts an article 1 to a position 4, the ends of the article 1 being coated with adhesive by applicator rollers (not shown) during this lifting. At the position 4 a pair of pushers (15, Fig. 3, not shown) push pieces of non-shrinkable plastics material against the ends of the article 1, these pieces being severed from two plastics strips (not shown) by cutters (14). A pusher 5 then pushes the article against interconnected webs 8, 9 of heat-shrinkable material and to a position 6. A pair of sealing tools 12, 13 are then operated to form the sheath and sever the sheath from the webs 8, 9. The article is then carried by a conveyer 19 through a heatshrinking tunnel 20 which contains a pair of heaters 22 for heating the ends of the sheath and the plastics pieces to a welding temperature. The article then passes between pressure rollers 23 and into a cooling tunnel 21.

Abstract: 704,389. Making pipes. OHIO CRANKSHAFT CO. Nov. 14, 1950, No. 27821/50. Classes 83 (2) and 83 (4). [Also in Group XI] Apparatus tor producing longitudinally welded pipe from a continuous skelp 10, Figs. 2 and 3, includes an inductor 12 for heating the edges of the strip to welding temperature, comprising a main conductor 16 adjacent the edges 14, 15, and surrounded by U-shaped laminations 28. A highfrequency supply is fed to blocks 23, 24 and passes through return conductors 19, 20 and end rings 17, 18 to the conductor 16. The blocks and conductors are hollow and liquid cooled. The pipe is driven past the inductor and the edges are forced together after heating by rollers. Alternatively, the pipe is stationary and the inductor is moved along it. In Figs. 5 and 6 the rings are replaced by the parts 17<SP>1</SP>, 18' connected to conductors 19<SP>1</SP>, 20<SP>1</SP>. The conductor 16 is in two parts 16A, 16B and is supplied with power from a transformer 40 mounted on two roller bearings 41 having curved tracks. The lower bearing members are supported on compression springs 42. The lower edges of the parts 16A, 16B, include fins 32 which extend into the gap between the opposed edges, Fig. 10, and include mutually insulated spacing pads 36, 39, Fig. 9, which rest on the pipe. Thus the inductor can move to conform with the weaving movements of the pipe. The inner surfaces of the conductor facing the pipe may have a highly polished coating 43 of chromium, nickel, silver, &c., to reduce its radiant heating by the pipe. Fig. 12 shows a flange 44 on the base of the fins 32. In Fig. 16 the fins are excluded, and the return conductors 19<SP>1</SP>, 20<SP>1</SP> are surrounded by magnetic laminations 28<SP>1</SP>. When, the pipe is thick a second inductor may be arranged inside it and opposite to the main inductor. Reference has been directed by the Comptroller to Specification 666,381.

The carburettor body comprises a cylindrical casing 2 for the primary air valve 25, a cylindrical casing 3 for the throttle valve 29 and a rectangular connecting portion 4 across which extends the tubular member 12 secured by a screwed plug 14. A portion of the wall of this member is removed and replaced by a flat piece 18, Fig. 4, in which is formed the fuel slit 19. The float-chamber arm 6 is secured by a screwed plug 9, and the upper end of member 12 is tapered and forced into a boss 17 screw-threaded on its exterior. The fuel passes to the slit by way of passages 10, 11 and 15 and a bore 22 in the lower end of the cylindrical member 20 which is bevelled as at 21, Fig. 6. The upper end of member 20 has a collar 23 which normally rests in a recess in the boss 17. The air inlet port is shown at 26 and the mixture outlet port at 30. Arms 33, 34, 35 clamped respectively to the fuel, air and throttle valves are connected together by a yoke piece.

Abstract: 823,418. Photographic cameras. DECKEL, H., and DECKEL, F. W. Sept. 14, 1956 [Sept. 15, 1955], No. 28171/56. Class 98(1) In a camera, the movement of at least one depth of field pointer can be restrained by engagement with a member carrying an object distance scale. In one form in which lens focusing member 8 carries the distance scale the engaged pointer 12 and the member 8 move together so that the operation of member 8 alters the diaphragm setting and the operation of the diaphragm alters the object distance setting. Alternatively pointer 11 is engageable with member 8. In another form, the lens focusing member 31 is couplable in different relative positions with an actuating member 32 of a built in range-finder 33 so that the ranged object may be at one limit of the depth of field. Preferably, the near limit depth of field pointer 43 carries the member 32 for rotation therewith while the other pointer 44 engages a stationary member 46 carrying the object distance scale. Notches 50 are provided in pointers 42, 43 and 44 for engagement with a spring pawl 40 carried by member 32. Alternatively one depth of field pointer may be restrained merely by a stop extending from member 8 at the infinity position. The number of notches in member 8 may be limited to two. Specification 744,962 is referred to.

Abstract: 1,018,062. Feeding webs. EMHART ZURICH S.A. July 24, 1962 [July 25, 1961], No. 28496/62. Heading B6B. A web 7 of plastic material unwound from a roll 8 is fed intermittently by a roller 18 co-operating with a pressure roller 11 to a reciprocable mould 4 co-operating with a stationary platen 2. The web is drawn away from the mould 4 by a roller 30 co-operating with a pressure roller 23. The feed rollers 18 and 30 are driven by rotary hydraulic motors 20, 31. After a moulding operation, during which the mould 4 engages a properly registered length of web, the rollers 11 and 23 are moved away from the web by cylinders 17 and 29, thus allowing resetting of the motors 20, 31 to their feed initiating positions under the control of a seaming unit, e.g. a photo-electric cell 36 which senses registration marks 37 on the web. During resetting, with the web at rest, the photoelectric cell is moved rearwardly longitudinally of the web until a mark 37 is located and the motors reversed by the hydraulic circuit described with reference to Fig. 2 (not shown). A signal generated by the photo-cell terminates the reverse setting motion of the motor 20, while resetting of the motor 31 is terminated by a piston 31b engaging a partition 31d. Control valves 46, 47 and 57 in the hydraulic circuit are actuated by solenoids the energization of which are controlled by a control circuit, Fig. 3 (not shown).

Abstract: 955,936. Labelling machines. MORGAN FAIREST Ltd. Feb. 15, 1963 [July 26, 1962], No. 28700/62. Heading B8F.  Relates to a labelling machine in which pressure pads simultaneously apply labels to opposite faces of an article. According to the invention, two pressure pads 23, 24, Fig. 8, with suction apertures are hinged together at 28, the pad 24 being movable between a position in which both pads are co-planar for simultaneously receiving two labels L from a pick-up member 55 and a position in which the pads 23, 24, Fig. 10, are face-to-face but spaced apart so that the labels are applied to opposite faces of an article 2 by inward movement of the pads. The movement of the pad 24 also causes a clamp 63 to engage the top 64 of the article during application of the labels. As shown in Fig. 1, the articles 2 are fed on a conveyer 1 via a pocketed disc 7 to a rotatable delivery member 9 from which they are taken by a discharge disc 10 and fed back to the conveyer, the articles with the labels thereon then passing between two endless pressing belts 14. The delivery member 9 carries six radial bracket arms, each having a pair of pressure pads located above an annular support plate 26. Labels are taken from a magazine 57 by a pick-up drum consisting of upper and lower sections of spaced discs 55, Fig. 8, previously gummed by a gumming roller 56, Fig. 1, the labels being transferred by suction to the coplanar pressure pads at position B of the member 9. At subsequent positions the article is introduced, the movable pad moves downwardly, the clamp is applied and the labels applied to the article. In the envent of omission of an article on the conveyer a detector device 66, Fig. 1, serves to move the gumming roller 56 and label magazine 57 to retracted positions.
