Title: Improvements in and relating to the manufacture of enamel ware
IPC: C03C3/118
Filed: 1929-10-17
Abstract: 336,797. Dougherty, W. E. Oct. 17, 1929. Enamels. - Titanium dioxide is used as an opacifier for enamels that do not contain fluorine. Calcium carbonate, or other suitable salt of calcium, barium, strontium, or magnesium is preferably added to the batch to intensify the opacity produced by the titanium. If the titanium tends to produce a yellowish enamel, small amounts of zirconium oxide or tin oxide are added to secure the desired whiteness. The titanium may be added to the foundation enamel which is applied directly to the surface of the metal article, and it is stated that it will not cause blistering. For the foundation enamel, 2-4 per cent of titanium dioxide is added to the batch materials, and when the mixture has been melted and pulverized, 4-15 per cent of titanium dioxide is added to produce the desired opacity. If cobalt is used in the enamel for the initial coating of metal articles, titanium may be added to the enamel batch in the form of rutile, and it is said to neuralize the bluish colour due to the cobalt.

[Also in Group X]  A method of tensioning wires for use in the production of pre-stressed concrete comprises anchoring the wires at one end, passing the wires at the other end of the mould beam or the like, each through a one-way grip device, gripping the wires individually in a second oneway grip device adapted to function in the same direction as the first moving the second oneway grip device repeatedly away from and towards the first to tension the wire and then releasing the second one-way grip device when the wire is held under predetermined tension between the anchored end and the first one-way grip device. As shown, wires 13 are anchored in a block B by means of one-way grip devices E, passed through a mould D and then through one-way grip devices F in a block C, the devices E, F operating in opposing senses. Each wire 13 is individually tensioned by a jack comprising a further one-way grip device A, operating in the same sense as device F, in a barrel 10 and a stop 14 to abut the anchor block C, the jack being operated by a standard torque wrench 31,  set to register or slip at the required tension, which is rocked backwards and forwards, the wire 13 being gripped by the device A on rearward movement and by the device F on forward movement until the required tension is reached. The devices A, E, and F are preferably one-way grip devices comprising an outer barrel with tapering bore and an inner cylinder carrying a plurality of balls co-operating therewith and the jack is preferably that described and claimed in Specification 792,659. In a further embodiment, ordinary wedge grips are used in blocks B and C and a removable head, having a one-way grip device, is placed up against the block C, the jack being used as previously. The tensioned wire is then held between the wedge grip in block B and the one-way grip device in the head and the wedge grip in block C is then used to anchor the wire and the wire released from the one-way grip device by a cam and the head removed. An adaptor, as described in Specification 792,659 may be used to convert existing wedge grips in the block C temporarily into one-way grips. Wires tensioned by this method may be finally further tensioned by existing apparatus.

A rocket motor 1 is divided by a partition 2 into two combustion chambers each containing a solid propellant charge together with an igniter therefor, at least one of the igniters being immediately adjacent the partition in which there is a port through which heat energy may pass from the igniter first ignited to ignite the second igniter. One charge may be a boost charge 3 and the other a sustainer charge 4, for which the igniter comprises a composition 5 housed in a cup 6 closed by a disc 7. The cup 6 is secured to the partition 2 by a spigot 9 and nut 8. The spigot 9 passes through the port in the partition and has an axial passage 10 communicating with the igniter composition. A passage 11 through the boost charge 3 leads from the primary igniter 12 to the partition 2. A primer (not shown) is used to ignite the igniter 12. Thermal insulation 13 lines the casing 1.

Title: Process for manufacturing films from casein
IPC: D01F4/00
Filed: 1931-11-19
Abstract: Casein is brought into colloidal solution in an alcoholic dispersion liquid, a coagulating agent added, and the solution poured upon a surface to form a film.  The colloidal solution is formed in the following manner.  The casein and an alcohol or mixture of lower alcohols are placed in a mixer together if desired with a plastifier such as glycerine or terpin hydrate, and an alkaline salt (sodium carbonate), an oxidizing agent (hydrogen peroxide), and more of the dispersion liquid are progressively and alternately added so as to avoid coagulation, the temperature of the mixture being at the same time gradually raised to 100 DEG  C. The colloidal solution obtained is submitted to electrolysis which has the effect of (1) dehydration, (2) transformation of the sodium carbonate to sodium hydroxide, (3) purification by deposition of microscopic impurities, and (4) displacement of the pH value.  A coagulating agent is then added, e.g., hexamethylene tetramine, formol, tannin, or trioxymethylene together if necessary with substances which affect the rate of coagulation, such as glycerine or propyl alcohol.  Acidification at this stage gives the products to be obtained a higher impermeability. The mixture is poured on to a glass plate or moving nickel-plated or chromium-plated iron sheet, and the hardening of the film accelerated by passage through a vacuum or by suitably raising the temperature. The treatment of the detached film comprises, (1) partial dissolution of the surface of the film, e.g. in glacial acetic acid, (2) hardening, simultaneously with (1) by means of organic liquids, e.g., butyl, propyl, or isoamyl alcohol, acetone, or benzene, (3) plastification by means of acetin, triacetin, engenol, cyclohexanol, glycerin, amyl acetate, butyl acetate, or the like. The films may finally be hot calendered.

A device for coupling a suction pipe 5, Figs. 2-4, to a vacuum cleaner comprises a pivotally mounted locking plate or ring 13 having a hole 20 therein which becomes aligned with the socket 10 to permit the end of the suction pipe 5 to be fitted therein when the plate is pivoted towards the opening 10, the plate 13 being biased by a spring 17a away from the opening 10 into binding relationship with the pipe 5, preventing accidental withdrawal thereof. The top of the vacuum cleaner is provided with a rotatable housing 3 having a hand-grip 7 and forming the air inlet passage 9 leading to the socket 10. The locking plate 13 is pivoted at 14 in a recess 11 formed between spaced walls 12 and is normally biased by the spring 17a to a position in which the opening 20 is slightly out of alignment with the socket 10, the movement of the plate 13 away from the socket 10 being limited by a lip 18 engaging a stop 19. A space between the bottom of the plate 14 and the housing 3 prevents the accumulation of dirt. In a modification, Fig. 5, the locking means comprises a ring 27 supported in a recess 24 so that it pivots about its bottom edge and connected to a spring-loaded push-button 33 which after insertion of the suction pipe, pivots the ring into locking engagement with the pipe. Dirt collecting in the bottom of the recess 24 escapes through a passage 52. The device is also shown applied to the blower outlet of a vacuum cleaner and is also applicable to the coupling together of two pipes.
