Title: A new and improved method of and means for forming hollow articles from thermoplastic material by blowing
IPC: A45D2/32
Filed: 1952-04-07
Abstract: 763,583. Blow-moulding extruded hollow plastic articles. PARFREY, F. T. Dec. 16, 1952 [April 7, 1952], No. 8827/52. Class 87(2). In making hollow plastic articles by blowing fluid under pressure into a length of tubular plastic material, the formed hollow article is cooled by permitting said fluid to flow continuously from within the formed article, the fluid being at such a temperature that it will cool the article. Thus, a tube T, Fig. 4, of plastic material is extruded downwardly from a nozzle C, and two die halves A, B close on the tube, the halves moving from the open position of Fig. 4 to the closed position of Fig. 5. As the die halves close, the tube is severed from the nozzle by a knife and a compressed air supply pipe 63 is raised to project into the tube. The die is then swung about pivots 68 to the broken line inclined position shown in Fig. 2 (the die being thus removed from the path of the continuously-extruded tube) and the article is blown. During blowing, compressed air leaves the article through a pipe 51, which is concentric with pipe 63, and a valve 54, this valve being adjusted to obtain the desired pressure within the article. The die is then opened, the air pipe is retracted, the blown article falls out of the die, and the die is swung back to the vertical position where it closes on the tube length that has been extruded whilst blowing has been taking place. The air pipes 51, 63 are moved by a pneumatic cylinder 49 housing a piston 52 and spring 56. The die halves A, B are cooled and are pivotally mounted on a member 18 fixed to a pneumatic cylinder 22 housing a piston 25 movement of which opens and closes the die halves. The machine is described in more detail in Specification 763,584.

Title: Improvements in or relating to apparatus for un-stacking crates or the like piled upon one another
Inventor: ARBER ROWLAND SACKVILLE PRESTO
IPC: B65G59/06
Filed: 1961-03-10
Abstract: 962,748. Unstacking. U.D. ENGINEERING CO. Ltd. June 8, 1962 [March 19, 1961], No. 8891/61. Heading B8C. Crates are unstacked in a machine having two pneumatically-operated lifting elements 78 and pawls 82 pivotally mounted on either side of a structure formed by posts 64-67. The pawls 82 may be moved into and out of engagement with ledges or cross-wires on the bottom but one crate in the stack. Crate supply.-Stacks of crates are supplied between fixed rails 53 on an endless conveyer 50, 51, the leading stack tripping a lever 59 to swing guide rails 54, 55 about pivots 57 (one shown), thereby deflecting a succeeding stack against an abutment 61. The lever 59 also causes a stop 62 to be raised to hold a stack in the machine; and the lips 79 of elements 78, each pivotable laterally on a carrier 76, are brought under the bottom crate. The third crate from the bottom operates a valve causing the posts 64, 65 to pivot inwards about vertical axes. Unstacking.-The elements 78 raise a stack on the automatic actuation of pistons 75. To each piston is secured a block 74 carried on a chain 73 and fixed to one of the carriers 76. The pawls 82, retracted before the elements 78 descend again, are subsequently caused to hook in below ledges on the bottom but one crate. The lips 79 are then withdrawn and the bottom crate is discharged on the conveyer 50, 51. The raising and lowering operation is repeated to complete unstacking. As the last crate descends, the guide posts 64, 65 are opened and the guide rails 54, 55 re-aligned. Should the crate outfeed be full, infeed of further crates is prevented. In a modification, Fig. 4 (not shown), a lost-motion device is inserted between the carriers 76 and the piston-rods 75 which raise them, so causing the lift mechanism to be raised should the descending crate meet an obstacle.

Title: Improvements in and relating to packing or sealing rings for shafts, bearings and the like
IPC: F16J15/32
Filed: 1951-04-17
Abstract: 695,408. Oil seals. FORSHAW, R. DUTTON-. April 9, 1952 [April 17, 1951], No. 8909/51. Class 122(v) In a rubber or rubber composition sealing ring comprising an annular body part 1 press fitted on or into its mounting and an integral resilient sealing lip 2 that may or may not be encircled by a garter spring 3 the annular body part 1 includes a resilient reinforcement 5 that is stressed when the seal is mounted so that it exerts a radial thrust to expand the body part against the mounting should the rubber shrink. The reinforcement 5 which may be wholly embedded in the rubber body may be a helical coil of round or square wire or plastic, a split flatsectioned annular metal strip or strips, or an L-section ring having its lateral part slit to form tongues one of which slits may also extend through the other part of the ring. The reinforcement may also be a bimetallic strip that tends to expand the sealing ring against its mounting when the ring is subject to heat, or it may be or have a core of natural rubber that swells due to contact with oil to expand the sealing ring against its mounting. When the reinforcement is non-rubber it may be coated with rubber or plastic before being embedded in the body part. If the reinforcement is helical and has a part exposed in the outer periphery of the sealing ring the exposed part is made non-continuous to prevent oil seepage.

Title: Improvements in or relating to thermostatic electric switches
IPC: H01H37/46
Filed: 1953-03-31
Abstract: 738,200. Temperature-responsive actuating-elements. POITRAS, E. J. March 31, 1953. No. 8970/53. Class 64 (2). [Also in Group XXXVII] An electric switch comprises a heatexpansible shell 10 enclosing a pair of non-expansible contact-carrying bowed strips 12 fixed at one end 21 to a disc member 20 hermetically sealed at 23 within the shell. The other end 41 of the strips is fixed to a plate 40 having a pair of diametrically-opposite protuberances 42 which abut a plate 43 provided with a threaded stud 44. The protuberances 42 permit pivoting of the plate 40 on the plate 43 to relieve the strips 12 of undesired stress. A sleeve 45 screwed over the stud 44 has an external thread of lesser pitch than the internal thread whereby rotation of the sleeve in a closure element 50 secured to the shell end causes axial movement of the end 41 of the strips 12 to vary the compression of the latter and hence the temperature at which the contacts 13 close. To prevent rotation of the plate 43 when the sleeve 45 is rotated and also to hermetically seal that end of the shell, a bellows 55 is sealed at its ends to the plate 43 and the closure element 50. The shell may be lined with an inner insulating sleeve 11. According to another construction (Fig. 5, not shown), the strips 12 are mutually convex and the contacts 13 normally in engagement.

Filed: 1945-04-11
Abstract: 607,285. Extruding. SOC. D'ELECTROCHIMIE, D'ELECTRO-METALLURGIE, ET DES ACIERIES ELECTRIQUES D'UGINE, and COMPTOIR INDUSTRIAL D'ETIRAGE ET PROFILAGE DE METAUX. April 11, 1945, Nos. 9069 and 9070. Convention dates, Nov. 22, 1941, and July 11, 1942. [Class 83 (iv)] In a method of extruding hot ingots, there is inserted between the ingot and the die or, in addition, between the ingot and other parts of the container an incombustible material which will melt at the working temperature, but will remain viscous and serve as a lubricant. Suitable materials are glass, oxides such as boron trioxide or phosphorus pentoxide, a salt such as borax or sodium metaphosphate, and certain natural or synthetic slags. In one form, Fig. 1, a glass plate 1 is put into a container 3 between the die 5 and the ingot 6 which is extruded through the die opening 4 by a ram 7. When extruding a tubular ingot 6 between'a die 3 and mandrel 10, Fig. 2, the mandrel may be surrounded by a glass tube 11 while annular glass plates 8 and 12 are placed between the ingot and ram and between the ingot and die. The die may be formed with a number of recesses 22 in its front face, Fig. 6, and with an annular recess 24 in the die opening in front of the narrowest portion. Such recesses serve as reservoirs for the viscous material and by improving lubrication, add to the life of the die. Instead of the material being used in the form of plates or tubes, it may be applied in powdered form, or as a solution or suspension of the material in a fluid which will evaporate in contact with the ingot or container. Alternatively, the hot ingot may be immersed in a bath of the molten material, the bath being used also to preheat the ingot. The work produced by the method is covered with a thin coating of the glass or other material which can be removed by mechanical action or by a suitable solvent. Specification 128,876, [Class 83 (iv)], is referred to.

[Also in Division H1] In a binary data store in which the magnetic vectors in the magnetic (thin film) cores are turned into the hard direction for read-out purposes and, in the process, produce eddy currents in conductors close to the cores, the arrangement and the crossfield interrogating pulses are such that the eddy currents produce fields which return the vectors to their previous (information) positions. The wide strip conductors 33, 34, 35 (Fig. 3) are packed closely with the film core 31 which can be provided with a highly polished metallic base-plate 32 which may act as a common return for the conductors and assists the formation of eddy currents. The sense conductor 33 may be slotted or may be formed only by the middle portion shown, the two outer conductors indicated at 33 forming the bit (drive) line. Coincident write-in is by conductors 34 and 35 respectively parallel and perpendicular to the easy axis and, in a matrix, forming the word and bit conductors. For read-out the crossfield drive pulses in 34 produce fields from two to six times the anisotropy field and terminate while the eddy currents they produce provide opposing fields sufficient to turn the magnetic vectors back to their original positions. Dimensions separating distances and methods of formation of the film cores for a matrix are given.
