Title: Two-position snap cap for containers
IPC: B65D47/14
Filed: 1962-06-21
Abstract: 943,728. Stoppers. M. B. STULL. June 21, 1962 [June 22, 1961], No. 23934/62. Heading B8T. A polyethylene two-position closure comprises a resilient orifice member 10 and a stopper member 12 provided with co-operable annular beads 40 and 54, 55 respectively for holding the stopper 12 in either of two closing positions, the bead 54 providing a stronger detent action than the bead 55 and thus holding the stopper 12 more securely on the orifice member 10. The member 10 is formed with external annular beads which provide a groove 32 to accommodate the rolled edge of a container 16. The container is further seated by a skirt 56, depending from the top wall 50 of the stopper 12, which is received within the restricted throat 36 of the member 10. In a modification, Fig. 3, the orifice member is constituted by the neck 65 of the container, a bead 72 being formed on the neck 65 to co-operate with either of the annular beads 88, 94. A tab 84 on the stopper is adjacent to the shoulder 68 of the container when the stopper is in the tighter closing position so that initial removal of the stopper is made increasingly difficult. In a further embodiment one of the annular beads on the stopper member is replaced by a second bead on the orifice member.

Title: Improvements in and relating to seamless stockings
IPC: D04B9/46
Filed: 1964-06-10
Abstract: The heel of a seamless stocking is formed by introducing part courses in the heel portion during continuous rotary knitting. For this purpose the stocking is knitted on a multifeed circular machine and during production of the heel some of the feeders continue to feed yarn and knit complete circular courses 9 whilst other feeders only feed and knit their yarns to form short courses 10 within the confines of a central portion 7, Figs. 2 and 3 (not shown).  The remaining feeders then feed and knit their yarns 8 to form short courses which are progressively varied and extend within the confines of irregular portions 8 on either side of the central portion 7. With this arrangement a pocket is formed in which the central portion 7 is composed of courses knitted at all the feeders whereas the marginal portions 8 contain a lesser number of courses and the instep knitted over the same period is restricted to courses knitted by those yarns which are continuously knitted throughout each revolution of the machine. Alternatively, instead of increasing the length of the courses in the portions 8 and then gradually reducing them as illustrated in Fig. 2, (not shown), the courses in these areas can be decreased and then lengthened.  The short courses may be knitted of thicker or stronger yarns.  Instead of knitting an additional short course extending beyond the edges of the central panel the main yarn may be reinforced over the same course length as would be occupied by the intermediate length course.

Patent GB-207876-A (GB)
Title: Method of and means for testing the hardness of metals and other materials
IPC: G01N3/50
Filed: 1922-09-07
Abstract: 207,876. Herbert, E. G. Sept. 7, 1922. Testing hardness of materials.-A method of measuring the relative hardness of materials comprises rolling a weighted test-member upon the surface of the material to be tested and measuring the time or amplitude of the swing. Apparatus for carrying out the method comprises a compound pendulum h, which is initially balanced in three planes by screws b', b<2>, b<3>, and swings about a hardened ball a the centre of curvatures of which is the centre of suspension of the pendulum. The tilt of the pendulum is indicated by an inclinometer f of the spirit level type. The centre of gravity of the instrument can be shifted by means of a movable mass b<4> screwed on a lixed shaft. Two independent hardness tests are made :- (a) Time test for measuring the indentation hardness (b) Scale test for measuring the resistance to working with a tool. The ratio of the results of (b) and (a) is said to measure the " flow hardness " of the material. In testing, the pendulum is placed upon the specimen c and oscillated; the amplitude of the first oscillation as shown by the spirit level is measured for the scale test and the time of oscillation is taken for the time test. The results, of the time test by the instrument are convertible into Brinell numbers and extend upwards into regions of hardness where the .Brinell test is not applicable. For specimens of nearly the same hardness the pendulum is rendered unstable by adjustment of the mass b<4> and the hardness compared by means of the time test.

Title: Improvements in or relating to processes of producing continuous castings of square or circular cross-section
IPC: B22D11/12
Filed: 1965-06-09
Abstract: 1,048,403. Continuous casting; working rods. GEBR. BOHLER & CO. A.G. June 9, 1965 [July 3, 1964], No. 24453/65. Headings B3A and B3F. A process for manufacturing continuous castings of square or circular cross-section, in which the continuous casting emerging from the mould in an oval or diamond cross-sectional shape is changed from oval to circular or from diamond to square by shaping in a closed pass defined by a pair of grooved rolls with utilization of the residual heat of the casting. Where withdrawal rolls are used in the process a pair of these rolls may be used to shape the casting as well as acting as straightening rolls. Alternatively, in addition to the grooved shaping rolls a pair of withdrawal rolls may be positioned behind the grooved rolls so as to maintain the casting under tension while it is being shaped which assists in the reduction of the crosssection. The grooved rolls may have a number of closed passes, one beside the other, so that different cross-sections may be obtained without changing the mould.

Title: Improvements in processes for the manufacture of cement
IPC: C04B7/40
Filed: 1921-09-16
Abstract: 194,738. Rigby, T. Sept. 16, 1921. Film evaporators.-In the manufacture of cement the slurry is dried before admission to the kiln in a steam-heated film drier of the kind in which evaporation takes place in a closed space substantially free from non-condensible gases. The drier may be. either single or multipleeffect, but in the latter case the slurry is preferably passed through the units in parallel. The waste heat of the kiln is preferably used to generate steam which is used, either directly or after driving an engine, for heating the film evaporator. The evaporator may be of the type in which the vapours generated are compressed and used to heat the same or another unit of the apparatus. The compression may be effected by a steam jet or a compressor operated by steam generated by the heat of the kiln gases. By leading the vapours from the drier to the condenser of the engine, the drying is effected at low pressure and temperature. Suitable types of drier are those described in Specifications 149,055, 150,068, 180,963, and 181,035. Fig. 3 shows an arrangement in which internally-heated drying-drums 25 are used in conjunction with smaller internally-heated drums 27 having a different peripheral speed to facilitate the distribution of the slurry, which is fed to the space enclosed by the drums 25, 27 and bridges 29.

Title: Food Freezing
IPC: F25D25/04
Filed: 1967-05-30
Abstract: 1,182,693. Freezing food. E.I. DU PONT DE NEMOURS & CO. 30 May, 1967 [31 May, 1966], No.24797/67. Heading F4H. Foodstuffs are frozen in a bath of a liquid, halogenated alkane refrigerant having a boiling point of from - 5 to - 50 C. and a density such that the foodstuffs float therein. The foodstuffs are allowed to fall freely into a part of the bath which is maintained in a turbulent state. As shown, foodstuffs 10 pass through a hopper 11, a vibrated chute 13, a vibrated hopper 14, valve 18, a vibrated chamber 20, valve 19 and vibrated chute 21 into a freezing chamber 29 which contains the refrigerant bath and a screw conveyer 32. Scoops 36 supply the foodstuffs to a discharge pipe 38 from which they pass through a valve 40, a vibrated chamber 42, valve 41, and chamber 47 (in which they are sprayed with dry air) to a collecting bin 43. Valves 18, 19 and 40, 41 are operated in a predetermined sequence such that loss of refrigerant vapour is minimized. A vacuum pump 45 removes refrigerant vapour from the foodstuffs in chamber 42 and this vapour, together with that from the outlet 52 of the freezing chamber passes to a compressor 53. The compressed vapour is condensed at 60 and passes to a separator 61 from which the liquid is supplied through a valve 63 into the liquid bath which it enters in the form of a spray 31 maintaining the inlet end of the bath in a turbulent state. Part of the vapour from separator 61 is returned to the compressor section under the control of valve 69 and the remainder passes through a condenser coil 64, cooled by refrigerant from the bath, to a further separator from which uncondensed gases are vented to atmosphere and liquid is supplied, via valve 67, to the bath. Should valve 63 be blocked by frozen moisture the  liquid level in separator 61 rises and a device 73, responsive to this level, causes the valve to repeatedly open and close until the ice is dislodged. Liquid from the bath may be circulated by pump 34 to spray nozzles 35 in the freezing chamber. An electrically heated vapourizer 76 is provided for separating food oils from the liquid refrigerant and returning refrigerant vapour to the compressor. The pitch of the conveyer may decrease in the downstream direction, (Fig. 2, not shown) or the conveyer may have a downstream section rotating more slowly than an upstream section.  Quantitative examples are described and preferred refrigerants, dimensions and operating conditions are specified together with a list of foodstuffs which may be frozen in the above apparatus.
