Title: Improvements in and relating to tobacco pipes, cigarette holders or similar smoking articles
IPC: A24F5/06
Filed: 1937-01-22
Abstract: 489,541. Moulding tobacco pipes &c. FREY, S. Jan. 22, 1937, No. 1914. [Class 87 (ii)] [Also in Group VI] The wooden bowl 2 of a tobacco pipe is coated with a thick layer 4 of synthetic resin. As shown in Fig. 1, the wooden bowl is placed over a protuberance 16 in a mould 14 and synthetic resin is cast around it. A plug 12 of clay &c. may be used to prevent the resin from entering the bore 8. A vent 28 is provided. In some cases, a mouth-piece 22 of resin is placed in position in the bowl 2 and the whole inserted in a mould that is heated and evacuated. Resin contained in an evacuated chamber containing the mould is then cast around the bowl, a washer 26 and a film of material to which the resin will not adhere being arranged between the mouth-piece 22 and the band formed as an extension of the covering 4. In some cases, the covering is moulded under pressure. Colourless or coloured resins may be used. The invention is stated to be applicable also to cigar or cigarette holders.

Title: Improvements in moulds for the production of blocks of silicate material
Inventor: SCHULZ ERNST OTTO
IPC: C03B19/08
Filed: 1963-01-16
Abstract: <PICT:0962526/C1/1> A mould for making blocks of foamed glass and like silicate materials is constructed from parts of a heat-expandable material such as unalloyed steel, each part being able to expand independently up to the maximum temperature used in the moulding operation at which temperature the parts become interlocked and relatively fixed, the top of the mould being releasable while the other parts remain united. The mould, Fig. 1, comprises a base-plate 1 to which guide bars 2 and clamp bars 3 are attached such that they diverge slightly outwards from bottom to top. Lateral walls 9 carry guide bolts 11 that slide within guide slots 5 in the bars 2.  End walls 10 have slots 13 that are engaged by hooks 12 on the walls 9, Fig. 4.  A cover-plate 14 with slots 15 is held in position by clamps 8 that pass through holes 7 in the clamp bars 2. The bars 2, 3 have holes or recesses 4 to reduce their thermal capacity. In use, clearances provided in the construction of the interlocking parts allow a limited independent expansion of the parts of the mould as it is heated up, the whole locking under the influence of the internal pressure set up by the expansion of foamed glass contained therein as it reaches the maximum temperature of the moulding operation.

Abstract: 472,471. Transferring and revaporizing liquefied gases. LINDE AIR PRODUCTS CO. Jan. 23, 1936, No. 2145. Convention date, Jan. 24, 1935. [Classes 8 (ii) and 102 (ii)] Liquefied oxygen, hydrocarbon, &c. is transferred from a supply vessel through vessels 40, 44 at successively increasing pressures to a vaporizing receiver 48 which supplies the resulting gas to consumers ; the transfer from the vessel 44 to the receiver is assisted by withdrawing a part of the liquid which is heated and circulated thermosiphonically in a heater 60, the resulting gas being caused to exert pressure on the liquid in the vessel 44 ; residual gas in this vessel is transferred to the previous vessel 40 where it is condensed by the liquid therein. Two sets of vessels may be arranged in parallel and used alternately to give a continuous supply ; the pressures in a pair of parallel vessels may be equalized and the gas remaining in a vessel just emptied thereby condensed ; a byepass allows gas from the heater 60 to pass direct to the gas discharge pipe 49. A vessel from which gas or liquid may be drawn may be connected to the pipe 66 leading from the vessel 44 to the heater 60. Specifications 307,070, [Class 8 (ii)], and 465,043 are referred to.

Title: Improvements in or relating to safety stop arrangements for machines
IPC: B21D43/02
Filed: 1953-01-26
Abstract: 745,650. Automatically stopping machinery. ABBOTT, F. D. April 26 1954 [Jan. 26, 1953], No. 2229/53. Class 80(2) A machine such as a continuously operating press is automatically stopped in the event of the automatically fed stock being buckled or otherwise diverted from its normal path by means of adjacent electrically energized feeler being engaged thereby. A press having a vertically reciprocable beam 10 operated by a crankshaft 12 is fed with a continuous strip of steel S through rollers 52, 53 operated by a ratchet mechanism 55, 56 and rod 58 from the crankshaft. The material passes through over dies 41, 42, 43, 44 and is finally cut by a knife 50. A driving clutch 16 is adapted to be disengaged by axial movement of a sleeve 19 carrying a projection 18 into the path of which a cam portion 17 of a lever 21 is moved. Withdrawal of the lever 21 against the pressure of a spring 22 is effected by actuation of the treadle lever 30 to engage the clutch and start the machine. The lever 21 is held in the clutch engaged position against the spring 22 by air pressure in a cylinder 35 which air pressure is under the control of valve mechanism 39. Arranged between the various dies are electrically energized feelers 64 which are normally spaced from the feed strip S but on being contacted owing to breakage, buckling or displacement of the strip, make an electrical circuit to operate through a relay the valve mechanism 39 to release the air pressure in cylinder 35. The spring 22 then moves lever 21 into engaging position to the projection 18 of clutch sleeve 19 to effect disenagagement of the clutch 16. An additional feeler device 71 is also provided after the feed rollers 52, 53 and a detector device 171 is also provided before the feed rollers which is actuated when the strip is exhausted to stop the machine as described above. An electromagnet or solenoid holding device may be employed instead of the pneumatic cylinder 35 for holding the lever 21 in the clutch engaged position. For stock of non-conductive material the feeler devices may comprise pairs of contacts which are pressed together by engagement with the stock or the stock may be coated with a conducting surface which is earthed.

[Class 40 (i)] [Also in Group XIX] In a linear-dimension gauge a member D, movable in response to the thickness of a workpiece S, moves axially a non-magnetic shaft 17, Fig. 3, carrying an armature 17a arranged adjacent relativelyfixed electromagnetic coils 15, 16, the shaft 17 being mounted on spaced concave-convex diaphragms 19, 20 of flexible resilient material. Generally, the apparatus is substantially as described in U.S.A. Specification 2,122,818, and comprises a fixed arm A, an arm B pivoted in a housing C to move an integral lever D relatively to the electromagnetic device M, and contact rollers on the arms A, B between which strip material S is fed. The device M is carried by a pivoted yoke E which is adjusted by a vernier means F against the action of a spring, and comprises a cylindrical non-magnetic casing 10, and cup-shaped holders 11, 12 for the coils 15, 16. The shaft 17 slides in sleeves 13, 14 and its ends are secured to the diaphragms 19, 20 which are fastened at their outer rims to the holders 11, 12. Normally, the diaphragms urge the shaft downwardly. The coils 15, 16 are supplied with A.C., and are arranged in a Wheatstone bridge circuit including a meter and rectifiers, so that unbalance caused by axial movement of the armature, consequent on varying thickness of the strip S, can be indicated. In a modification, where a larger current is required to operate a pen &c. recorder, two coils are arranged in each holder 11, 12. Each pair of coils is connected in parallel between the A.C. source and a rectifier, the rectifiers are in series, and a meter is connected in parallel with the rectifiers.
