Abstract: 862,354. Paper-making machines &c. DIAMOND NATIONAL CORPORATION. Sept. 15, 1959 [Feb. 17, 1959], No. 31480/59. Class 96. [Also in Group V] A pulp sheet forming machine, e.g. a Fourdrinier or cylinder type paper-making machine, has a plurality of parallel forming wires 32 to which is attached at intervals a plurality of solid projecting elements 36, the wires being deformed into secure interlocking engagement with the bodies of the elements at their points of attachment. In order to attach the elements 36, the wires 32 are first placed over a die 50 (Fig. 5) having spaced apertures or wells 52 contoured to form the elements by casting, in which, e.g., an " incompressible " metal or plastic or rubber composition, is poured into wells 52 and caused to overflow slightly to produce domed ends to the elements as shown in Fig. 3. Where a rubber composition is used, a diaphragm having perforations registering with the protuberances is placed over the screen and the composition is forced through the perforations. An alternative method of deforming the wires 32 is to punch holes through them, the holes having frayed wire edges which penetrate into the bodies of the elements to securely interlock with them.

Title: Improvements in moulding pulp articles
IPC: D21J5/00
Filed: 1935-11-16
Abstract: 461,372. Moulding pulp. MOULDED PULP CORPORATION. Nov. 16, 1935, Nos. 31824, 31825, and 31826. Convention dates, Jan. 25, Feb. 11, and March 9. [Class 87 (ii)] Hollow articles are moulded from pulp by introducing a suspension of fibres into a foraminous mould under a pressure not substantially above atmospheric, introducing a second liquid while the pulp is in a loosely matted condition so as to flush the partially laid pulp to continue its deposition and smooth the inner surface, and subsequently introducing a gaseous medium to complete the deposition and compact the fibres into a rigid wall. Pulp in a container 10 is introduced into the mould 17 by gravity through a nozzle 25 at a super-pressure up to about 10 lbs. per sq. inch. A flushing liquid is then introduced from a tank 23 through the pipe 24 under a pressure of 10 to 30 lbs. per sq. inch supplied from an air compressor 45 through pipe 46. After the pulp fibres have been thus evenly deposited, a short blast of air is admitted under a pressure of 20 to 45 lbs. per sq. inch from the container 26 through the valve 30 to drive out the residual water. Air under higher pressure up to 65 lbs. per sq. inch is finally admitted from a container 40 through a pipe 42, the air being preferably heated to about 675‹ F. by a burner 39. The moulded article can then be removed by separating the mould after the pressure has been relieved by opening valve 43. The moulded articles can be dried by passing through a drier on an endless belt. In a modification, the first pulp suspension may contain relatively coarse fibres while the flushing liquid in the tank 23 may comprise a thinner suspension of finer fibres which form a smooth inner surface on the article. If an impervious inner wall is desired, the second suspension may comprise nitrocellulose fibres which are subsequently caused to coalesce by spraying or otherwise treating the interior of the moulded article with a suitable solvent such as acetone, methyl alcohol &c., with a plasticizer such as dibutyl phthalate. Another suitable suspension comprises a paraffin emulsion containing cornstarch, wax emulsion and aluminium sulphate. In this case the moulded articles are pressed between heated dies, Fig. 4, to melt the paraffin. Suspensions of lacquers, gums or resins may also be used.

[Class 28 (i).] Apparatus for applying icing and piping to the sides of cakes, and for making " saucer " tops and bottoms on cardboard or gum-paste discs, comprises a base plate having slots along which the standards A, B, Fig. 1, are adjustable and are clamped by screws A<1>, B<1>, and other slots along which uprights J, L, Fig. 12, are similarly adjustable, these uprights serving to support members for applying and shaping the icing. The standard A carries a revoluble disc C having a centre spike C<1> and other spikes F screwed through the disc, the spikes serving to hold the cake, in co-operation with similar spikes D<2>,F on a disc D journalled in the standard B. The disc C and the cake are turned by the handle A4. To effect angular measurements on the cake, a strip is inserted in a slot E<2> in a stationary bush E, the strip having an opening through which readings on the scale E<2> can be observed. The disc C may be locked in the desired position by a screw A3. The disc D is journalled in the upper part of the standard B which is pivoted at B<5> to the lower part. A quadrant B4 having holes B<7> is screwed to the upper part, so that by means of a pin inserted in the hole B<6>, the cake may be held by the disc D alone, in an inclined or horizontal position. The uprights J, L, Fig. 12, have a series of holes J3, L<3> which serve to support a member M having extensions M<1> which are inserted in the holes. Members K<2> are adjustable along the member M to correspond with the size of the cake (shown in dotted lines in Fig. 12), the members M, K<2> having ledges which support a die M<3> which shapes the icing applied to the side of the cake. For piping the sides of cakes, a graduated bridge member is supported by the uprights J, L at the same level as the top of the cake. The icing bag is positioned 'by a member slidably adjustable on the graduated bridge. As shown in Fig. 8, a cardboard or like disc K<6> is secured on the disc C, the centre spike C<1> passing through the disc K<6> and a screw C<5> entering another hole. The disc K<6> is kept. against the disc C by a tube K' having a flared end which is passed over the spike C<1> and is carried by a bar K supported by the standard J. The die K<5> is supported by a ledge K<1> on the bar K and by ledges K<4> on slidably adjustable members K<2>.

Abstract: 299,896. Uhde, G. F. Nov. 3, 1927, [Convention date]. Ammonium phosphate and sulphate.-In fixing ammonia to form fertilizers, a, portion of the ammonia is oxidized to form nitric acid, which is used to treat crude calcium phosphate in quantity such that only calcium carbonate contained in it is acted upon. yielding a solution of calcium nitrate. The treatment may be carried out by suspending the phosphate in calcium nitrate solution and adding nitric acid gradually or bubbling through nitrous gases from the oxidation of ammonia, or by treating the phosphate with a solution containing calcium nitrate and nitric acid. The residual calcium phosphate is treated with sulphuric acid yielding phosphoric acid solution, which is neutralized with ammonia to form ammonium phosphate and calcium sulphate, which is transformed by ammonia and the carbon dioxide in the nitric acid treatment to yield ammonium sulphate and calcium carbonate. Other fertilizing agents such as potash may be added.
