Title: Machine for printing resilient articles
Inventor: HARPER MARY APPLEBY
IPC: B05C9/02
Filed: 1952-04-03
Abstract: 723,030. Printing on resilient articles. DUNLOP RUBBER CO., Ltd. March 23, 1953 [April 3, 1952], No. 8488/52. Class 100 (2). Apparatus for printing on resilient articles such as play-balls comprises means for applying a solvent for the printing composition to a portion of the surface of an article, means for applying printing composition to the same portion, a drying chamber, means for intermittently feeding the articles one by one to the means for applying the solvent and printing composition and to the drying chamber and mechanism for correlating the operation of the feeding means with the aforesaid applying means. A series of carrier plates 1, Fig. 1, have central apertures to receive the balls 20 and are attached to endless chains 3 passing over pulleys and drawing the plates over a guide 2. Mounted for vertical reciprocation above guide 2 is a pneumatically operated platen 6 having a pair of pressure-plates 7, 10. The plate 7 carries an absorbent pad 8 kept impregnated with solvent by a drip feeder 9. A paper web 11 is fed from a roll 12 under plate 10 through feeding means 13 to take-up roll 14. The web carries a printing composition, e.g. as described in Specification 713,264. As the balls pass under the plates 7, 10, the platen descends as shown in Fig. 3, flattening the balls and coating that part of the ball in contact with the pad 8 with solvent and applying printing composition from web 11 to the same part of the ball under plate 10 (which was coated with solvent in the previous operation of the platen). The balls then pass out from the platen, through the drying chamber 15 and fall into a delivery shoot 16. A timing device 17 controls the plunger 5 operating the platen 6, the motor 18 advancing the chain 3 and the motor 19 feeding the web 11 so that their various actions are correctly co-ordinated. In a modification the paper web 11 may be replaced by a multicoloured printing block composed of an assembly of coloured composition, e.g. as described in Specification 713,248.

This second frame is mounted on a third frame 3 for pivotal rotation in a vertical plane, whilst the third frame is so carried on a vehicle chassis 1 as to be able to rotate about a vertical axis. The rear group of sprockets 155 are the driving sprockets, whilst the nose portion 132 carrying the shaft 125 of the first group of sprockets 123 is adjustable with respect to the first frame in order that the chain-tension can be adjusted; the shaft 125 has secured thereto cutter discs which flank the cutter chains. This head is provided with piping 172 and suitably disposed openings to permit water spraying to suppress dust. As the picks 119 of the chains attack the face, the disintegrated mineral is carried back on the upper run of the chains to be discharged into a hopper 7 provided with breakers 182 and means 183 for freeing any mineral remaining attached to the chains before the return run to the face. This mineral drops through the hopper on to a scraper conveyer 8 carried by the second frame. and this conveyer discharges the mineral on to a further conveyer 9 disposed on and transversely adjustable with respect to the chassis of the machine, by hydraulic jacks 24. A scoop 13 clears the floor and any material picked up thereby is fed to the transverse conveyer by a conveyer 11. To allow the machine to operate in either direction without turning the chassis the conveyers 9, 11 are duplicated, being disposed symmetrically about the vertical axis of rotation of the third frame. A roof engaging jack 27 is situated on this vertical axis of rotation for anchoring the machine during the period when the disintegrating unit acts on the face. The hopper is provided with a yieldable hood 178. Specifications 664,521, 674,714 and 681,364 are referred to.

IPC: C03B7/08
Filed: 1916-06-19
Abstract: 104,606. Jaclcson, W. J. Mellersh-, (Hartford-Fairmont Co.). June 19, 1916. Delivering molten metal.-A method of intermittently feeding molten glass consists in severing successive charges from a stream of glass flowing through a heated chamber by means of shears which are introduced through apertures in the walls of the chamber, and then reheating the cut end of the stream. The viscous glass flows from a spout or through an orifice 7 in a conduit attached to a melting-tank 6. The conduit may be arranged so that the glass flows by gravity, as shown; or its flow may be regulated by suitable paddles or displacers. The stream of glass from the orifice 7 flows through a heated chamber 16, the temperature of which is regulated to the desired degree. Openings 36 are provided in the walls of the chamber through which shear blades can be introduced and withdrawn, and outside the chamber, means are provided for cooling the shear blades. The blades are driven into the chamber and withdrawn and sever a charge from the suspended mass of glass, which drops through the chamber into a receptacle 17. A gas flame from a burner 19 may be used to regulate the temperature of the chamber, and the flame also melts the end of the cut stream and thus minimizes the scarring of the glass due to chilling.

Title: Improvements in processes for the manufacture of glycerine by fermentation
IPC: C12P7/20
Filed: 1930-03-18
Abstract: In the production of glycerine by fermentation of carbohydrates in presence of an approximately neutral mixture of soluble sulphite and bisulphite, the mash, after fermentation has proceeded as far as desired, is made alkaline by soda ash or other mild alkali, the volatile products are distilled off--preferably after removal of the ferment--the liquor is then made substantially neutral by sulphur dioxide, sulphurous acid, or a soluble bisulphite, and is added, preferably in portions at intervals, to fresh carbohydrate with or without fresh ferment.  A concentration of up to 25 per cent of sugar may be employed.  In an example, 300 gallons of molasses containing 2240 lb. of fermentable sugar are diluted with water to make 1161 gallons, and fermented at 35 DEG  C. by 22.40 lb. of yeast. 350 gallons of a solution corresponding to 495.8 lb. of neutral sodium sulphite and 448.6 lb. sodium bisulphite are added in 40 gallon portions each hour until a sulphite concentration of 3 per cent is attained; this concentration is maintained by adding the sulphite solution as necessary.  After 4-5 days the liquor is allowed to settle, is freed from insoluble matter by filtration, made alkaline by adding 273 lb. of soda ash, and distilled to remove acetaldehyde and alcohol.  The 670 gallons of still-liquor containing 575 lb. of glycerine is treated with sulphur dioxide until the same r H value 6,7 as previously is reached, and this approximately neutral liquor is added as before to 1060 gallons of an aqueous solution of 290 gallons of molasses containing 2215 lb. of sugar, along with 20 lb. of fresh yeast.

Abstract: 1,209,272. Purifying phosphoric acid. ISRAEL MINING INDUSTRIES-INSTITUTE FOR RESEARCH & DEVELOPMENT. 23 Feb., 1968 [6 March, 1967], No. 8876/68. Heading C1A. Purified phosphoric acid is recovered from technical grade phosphoric acid by extraction with a solvent which, at the temperature of the extraction, forms a three-phase H 3 PO 4 -H 2 O- solvent system, which stratifies into three layers, the bottom one, containing H 2 O, H 3 PO 4 , and impurities, being discarded, and the phosphoric acid/solvent phase is submitted to a treatment which causes release therefrom of purified aqueous phosphoric acid solution. The H 3 PO 4  may be released from the extract by heating the extract to such a temperature that the three-phase system becomes a twophase system, whereupon aqueous B 3 PO 4  separates as the lower layer, or alternatively water may be added to achieve the same effect, or a combination of both methods may be used. 0À1 to 5% by weight of H 2 SO 4  may be added to the initial acid to promote its extraction, the solvent is preferably a di-lower alkyl ether, and the process may be operated continuously. A modification of the process is described wherein after formation of a three-phase system just enough H 3 PO 4  is added to cause the system to change to a two-phase system whose upper organic phase is then separated into two phases, the lower of which is the product aqueous H 3 PO 4 .

Title: Improvements in or relating to artificial teeth and to means for fixing the same
IPC: A61C13/10
Filed: 1920-03-29
Abstract: 169,731. Joannides, C. March 29, 1920. Teeth, artificial.-An interchangeable tooth, of the type in which the porcelain is slotted to engage a rib on the metal backing, is so constructed that the backing terminates before reaching the cutting-edge and the remainder of the lingual surface of the porcelain is sloped off to the cutting-edge. In the form shown in Figs. 1, 2, and 3, the backing h terminates in an undercut lip d formed on the porcelain tooth a. The cutting- edge b lies in the plane of the lingual surface c of the porcelain, and the rib f is tapered at its upper end to the external contour of the tooth. The rib f extends further towards the cutting- edge b than does the backing h and in section may be dovetailed, triangular, as shown in dotted lines in Fig. 3, or of other form. Fig. 6 shows a modification having a non-undercut lip d extended at its edges k. In other modifications, the cutting-edge may be situated in front of the plane of the lingual surface of the porcelain, or the projecting lip d may be omitted. The Provisional Specification describes also interchangeable teeth with metal-lined sockets to receive securing-pins, metal backed teeth in which the metal backing-plates are formed with slots or holes for pins which are secured in these slots &c. by cement, and pin teeth having wedgeshaped pins which may be of flattened cross-section, may be inclined or bent towards the cutting edges of the teeth, and may be relatively inclined to prevent drawing out. Reference is also made to pins which, in cross-section, are round, triangular, or flat with V-shaped edges and may be roughened or serrated. The teeth may be fitted with two pins, or with a single pin and a lip as described in the Complete Specification. The undercut edge of the lip may be arched so that it may be formed by a revolving wheel or cutter.

Title: Method of making race inserts
IPC: F16C33/64
Filed: 1967-02-27
Abstract: 1,148,692. Making bearing race inserts; bending; coiling; rolling. FMC CORP. 27 Feb., 1967 [28 March, 1966], No. 9164/67. Headings B3A, B3E and B3M. A method of making bearing race inserts comprises shaping a blank 12 into a coil by rolling between rollers 14, 16, 18, 20 having mating concave and convex surfaces and cutting the coil into a plurality of race inserts. The upper rollers 14, 18 are mounted on shafts in eccentric sleeves which are rotatable to allow for vertical adjustment of the rollers. The rollers force the strip against a shoe 64 which deflects the strip into a coil of predetermined radius. The strip has a curved transverse cross-section and the shoe 64 is set to deflect the strip in such a way that the concave surface is external or internal depending on whether an inner or an outer insert respectively is required. The intermediary coil for internal inserts is placed on a mandrel (70) and cut into rings by a rotary cutter (74) travelling axially thereof, Fig. 2 (not shown). The intermediary coil for external inserts is placed in a sleeve 80 and cut into rings by a cutter 84. The rings are placed in perforated cylinders for heat treating. To prevent excessive expansion or contraction the internal inserts are restrained by plugs 92 and the external inserts have an elongated block placed between their opposed free ends. The perforations in the cylinders allow a quenching medium to reach the unexposed sides of the inserts. Hard metals such as stainless steel may be used without heat treatment. Instead of forming an intermediary coil, each strip may be formed into an individual insert, the only machining being trimming of the ends, if necessary.
