Title: Improvements in or relating to apparatus for use in the manufacture of rubber goods and process of handling such goods during manufacture
IPC: B29D30/06
Filed: 1922-02-02
Abstract: 198,402. Sloper, T. Feb. 2, 1922. Addition to 169,525. Tyre covers, stripping from cores.-In apparatus wherein the tyre band D<3> is removed from the support D by relatively decreasing the pressure in a chamber E bounded by the band, a co-operating memlrer B, and flexible sealing lips B<2>, as described in the parent Specification, the reduction of pressure in the space E is replaced or supplemented by an increase of pressure at the joint D<2> between the band and the support. In the form of the invention illustrated in Fig. 1 this is effected by enclosing the apparatus in a drum A to which compressed air is admitted through a pipe F. In the modification shown in Fig. 2 compressed air is admitted to annular spaces N enclosed by flexible sealing lips M<1> which make contact with the support D. Fig. 3 illustrates another modification having a single annular space P<1> surrounding the cooperating member B, and enclosed by sealing lips P<2> which may themselves be pressed against the tyre support by admitting compressed air to the space P<3> behind them. The apparatus comprises suitable pipes and valves for connecting all the air-spaces to high, low and atmospheric pressure.

Filed: 1943-02-25
Abstract: 564,486. Testing joints. ZWICKY, J. F. Feb. 25, 1943, No. 3132. [Class 106 (ii)] [Also in Group XXVIII] A device for testing the fluid tightness of welded, soldered, brazed, riveted or other joints and for the detection of fractures in vessels and sheets comprises a nozzle 3 surrounded by a yielding mouthpiece 4, a connection 6 on the nozzle for attachment to a source of fluid pressure, and a spring-loaded valve 7 for closing the nozzle when not applied to a joint. In Fig. 2, when the mouthpiece 4 is applied to the part to be tested, the operator squeezes the handle 11 and a bar 12 towards one another to depress the valve 7, whereby fluid pressure is supplied. Fig. 3 shows a simpler modification in which the valve 16 is opened when the stem 17 abuts the part to be tested. Leakage of fluid may be apparent in many ways according to the fluid used, e.g. water, paint, alkaline or acid liquid or liquid carbon dioxide.

Filed: 1923-02-03
Abstract: 215,102. English Electric Co., Ltd., and Bolton, R. A. R. Feb. 3, 1923. High potential switches have the conductors leading to the contacts arranged concentrically and the switch movement takes place in the region where the inner conductor extends beyond the outer and in a direction substantially parallel to the conductors. In the construction shown in Fig. 1, the inner conductor is the operating rod 18 and carries eight symmetrically arranged contacts 21 which are pressed uy springs 20 against a fixed contact 7 on the outer conducting tube 6. In the modification shown in Fig. 3, a conducting tube 6 carries a bell shaped fixed contact 7, whence the current passes through six contact fingers 21 and leads 28 to an inner tube 23. The fingers 21 are pivoted to a member 26 on the operating rod 18. the member 26 sliding in slots in the lower end of the tube 23. When the rod 18 is depressed the fingers 21 move downwards with it till rollers 31 engage a reduced portion 32 when the fingers fly outwards under spring actuation and the electrodynamic action of the current. In the modification shown in Fig. 5, concentric tubes 6, 23 carry fixed contacts 16, 4 provided with renewable sparking extensions 20, 21, and bridged by a funnelshaped member 13 carrying two circles of spring pressed contacts 12, 10 which engage the contact 16 and two circles of spring pressed contacts 8, 7 which engage the contact 4. When the operating rod 18 carrying the member 13 is depressed, contact is broken first at 20 and later at 21, the ars producing an upward rush of fluid which helps to extinguish them. Other modifications are described. Specification 179,815 is referred to.

A cylinder 90 is first actuated to swing the pallet 56 to position 56b and a cylinder (78), Fig. 4 (not shown), is then actuated to raise it to the position 56a and at the same time a cylinder 24 is actuated to move the mould section 16 to the position 16a, the mould section pivoting about studs 34. A cylinder (154), Fig. 2, is energized to operate a set of knock-out pins in the mould section to eject the cast grid on to the pallet, which is then lowered by the cylinder (78) and pivoted over to the trimming mechanism by the cylinder 90. The grid slides forwardly on the pallet to engage the stop bar 106 and a cam follower 134 engages a cam 136 on a shaft 138 to actuate links 130, 126, 124 to retract the bar 106. The grid slides between rolls 100, 102 and on to a support 54 of the trimming mechanism. Saws 52 trim the grid, after which it is released to slide on to a stacker plate 144. A linkage 150, 152 is then actuated by a cam (not shown) on the shaft 138 to convey the grid up rails 140 by pivoting the plate 144 to a position 144a where the grids are stacked vertically on the rails 140. To service the mould sections latches 36 are disconnected from the studs 34 and the mould section 16 is shifted forwardly by the cylinder 24. An arm is swung beneath the mould section to support it and a pivot bracket 44 is released from supports 18 to enable the mould section 16 to be swung about a vertical hinge to the position 16b.

Title: Improvements relating to the electrolytic production of sterilising agents, germicides and the like, and to processes of applying such agents
IPC: C25B1/26
Filed: 1928-02-06
Abstract: 311,253. United Water Softeners, Ltd., and Higgins, E. B. Feb. 6, 1928. Chloramines and hydrogen, obtaining; electrolytes, circulating; liquids, treating; electrodes.-A sterilizing and germicidal agent consisting of mono-chloramine or dichloramine or both together with a relatively small proportion of free chlorine, is obtained by electrolysis of a solution of an alkali metal chloride in the presence of ammonia or a soluble ammonia salt. The process may be carried out in an earthenware or glass cell comprising an upstanding internal tube y enclosing metal gauze electrodes n<1>, n<2> of large area relatively close together. The tube y communicates at the bottom by an aperture y<1> with the outer space into which ammonium chloride crystals are introduced through a mouth normally closed by a stopper l<1>. The vessel is filled with electrolyte to the top of the tube y. Chloramine is liberated at the anode and hydrogen at the cathode; these are carried off through the outlet z<2> by a current of air introduced by a tube z<1>. Alternatively the cathode may be enclosed in a porous pot and the hydrogen withdrawn separately. When the high current densities are used, the cell may be cooled by immersion in water. Ammonium alum or di-ammonium hydrogen phosphate may be used as the ammonium salt. Alternatively the electrodes may be immersed in a solution of the ammonium salt with the alkali metal chloride between, or a solution of ammonia may be allowed to drip on the electrodes or gaseous ammonia may be mixed with the alkali metal chloride solution. The chloramines may be stored in a vessel protected from heat and bright sunshine. The process may also be carried out and applied to the sterilization of a water supply in the apparatus described in Specifications 22280/12; 253,623, [Class 1 (ii), Inorganic compounds, other than &c.], and 311,218, also are referred to.

Syrups are prepared by heating melamine and aqueous formaldehyde in absence of oxygen. Dissolved oxygen may be removed from aqueous formaldehyde by passing an inert gas, e.g. nitrogen, through it before or after addition of the melamine but before heating, or the aqueous formaldehyde may be boiled in presence of an inert gas before addition of the melamine. Condensation is preferably done in an inert atmosphere, e.g. of nitrogen. The reaction is slower than usual and the permissible pH range may be extended without making the reaction time unduly short.
