Title: Improvements in or relating to jaw breakers
IPC: B02C1/04
Filed: 1935-07-05
Abstract: 444,784. Crushers with vibrating jaws. KRUPP GRUSONWERK AKT.-GES., F., Buckau, Magdeburg, Germany. July 5, 1935, No. 19279. Convention date, Sept. 1, 1934. [Class 59] In a jaw-crusher, the jaws of which lie one over the other to form an obliquely extending crushing gap, and the lower jaw, at least, is movable, the inclination of the breaking surface of the lower breaking jaw increases, in relation to the horizontal, in the direction of the delivery gap whereby a rapid discharge is effected and choking is prevented. The moving jaw 4 may be pivoted at 5 and operated by an eccentric 6, the crushing plate 3 being increasingly inclined toward the lower end c. The upper fixed jaw 2 may be shaped to correspond to the lower jaw 3. The stroke and speed of the eccentric may be increased so that the material takes a zigzag path in the lower part of the gap or a projecting movement in the direction of the delivery gap.

Title: Improvements in or relating to the production of ceramic compositions
Inventor: MOORE NORMAN CLEMENT
IPC: C22C1/10
Filed: 1951-08-16
Abstract: A process for the production of a ceramic material comprises forming a mixture of alumina and chromic oxide, adding thereto a quantity of carbon sufficient to react with part or all of the chromic oxide to reduce it to chromium metal, and subjecting the mixture to heat treatment, which may be effected at sub-atmospheric pressure, at a temperature at which the carbon and chromic oxide react to reduce all or part of the chromic oxide to chromium metal.  The mixture of alumina and chromic oxide and carbon may be prepared by mixing and grinding the ingredients or by co-precipitating the hydroxides of aluminium and chromium, heating the hydroxides to convert them to the corresponding oxides and mixing the oxides with carbon or by forming a solid solution of the oxides and pulverizing and mixing it with carbon.  The proportions in the mixture are adjusted to yield a fired material which consists of a solid solution of alumina with up to 5 per cent. of its weight of chromic oxide and a proportion of metallic chromium which is 10 to 70 per cent. and preferably 10 to 50 per cent. by weight of the product.  The mixture may also contain up to 5 per cent. of one or more of the oxides of silica, iron, magnesium, calcium or zirconium.  Specification 676,441 is referred to.

Abstract: 331,384. Booth, V. June 26, 1929. Disc and like mills.-A disc mill comprises a fixed disc 2, Fig. 2, and a rotating disc 1, means for passing the material to be ground radially outwardly from the centre, rotating beaters 10 moving peripherally of the grinding members and adapted to return coarse material through an opening 12 for regrinding, a screen 11 surrounding the discs, a closed casing having side walls 55, 56 contacting with the edges of the screen and a circumferential wall 30 spaced peripherally from the screen, a charging hopper 24 communicating with the centre of the discs and a discharge opening disposed beneath the discs. The fixed disc 2 is secured to the wall 55 by bolts 7 passing through screwed bushes 8 which bear directly, or through washers, on the side of the stone, to adjust its position relatively to the wall. The disc 1 is secured by bolts 7 to a disc 6 keyed to the rotary shaft 3, the disc 1 being positioned relatively to the disc 6 by bushes 8 and circumferential bolts 9. The discs are adjusted toward one another by a screw 21 acting on the end of shaft 3 which is contained in a housing 15 resiliently connected to the bearing casing 18 by springs 19. When a foreign body enters between the discs, the disc 1 and shaft 3 move axially to compress the springs 19. The material from the hopper 24 is fed to the centre of the stones by a screw 25, the stones being dished to provide an entry throat. The guiding surface of the stones or steel discs may consist of an external ring of fine radial serrations 39, Fig. 4, and an internal coarse ring 40, some of which are extended to the centre of the stone. Peripheral bands 38 encircle the stone and overlap the end of the serrations. Beaters 10 are secured to the disc 6 and assist in breaking up the material after passing through the grinding members and they also direct any material too coarse to pass through the screen 11 to a hole 12 for return to the hopper. Air passes into the machine through a hole 27 and leaves by the hole 12. The screen 11 surrounds the discs and rests on ledges in the side wall, the ends of the screen being secured by bolts 59, Fig. 1. The casing 30 surrounding the stones is also removably fixed by bolts 32 so that the casing and screen may be removed for access to the stones. Specification 292,838 is referred to.

Cow-milkers. - A teat-cup or inflation is characterized by a rubber inner wall or liner which is supported on a resilient ring at the extreme end into which the teat is received, in order to provide a smooth uninterrupted orifice. In the drawings, g<1> is the metal outer casing and b the rubber inner wall. At the extreme teat-receiving end the inner wall is bent back over the resilient ring a and is secured to the metal ring e which is recessed to take the spring f. The lower end of the liner is doubled back over the casing at g<3> and an air-tight joint is made by means of the metal cap h. The resilient ring a may be solid, cellular, hollow, or in the form of a metal coil spring, and is interchangable with other rings in order to vary the size of the opening. A hollow ring may be connected with a source of pressure or vacuum, or to the pulsations obtained by known forms of milking machines. If required, the inner liner may be doubled back over the casing g as is indicated by the dot-dash line in Fig. 1. By means of a side-tube j, the space between the inner and outer walls is subjected to pressure or vacuum as desired.

Filed: 1945-08-01
Abstract: Jelly powders, soluble in cold water or milk or other cold aqueous liquids to give a solution which sets to a jelly in a short time, are made by atomising an aqueous colloidal solution containing gelatine and a weight of sugar, e.g. sucrose, a mixture of sucrose and dextrose, a mixture of lactose and fructose, in excess of the weight of gelatine and drying the atomised solution in a current of hot air or inert gas, e.g. at 70-80 DEG  C., the pH of the solution being such that the dried product when dissolved in 10 parts by weight of water gives a pH between 4 and 5.  Before atomisation there may be added edible water-soluble materials and flavourings, e.g. pectin, dried milk, spices and condiments such as mustard, fruit and vegetable juices. Salt, if added, should not exceed 1 part per 7 parts of sugar. After atomisation, the powder may be mixed with dried milk, condiments such as mustard, glucose or sugar.  Examples describe spray-drying of a mixture of a solution of gelatine and citric acid and a hot solution of glucose and sucrose containing colouring matter, to which mixture raspberry flavouring has been added, a mixture of a hot solution of sugar and gelatine and the screened juice of black currants, and a mixture of sugar, tomato juice of 3 per cent solids, gelatine and salt.

Title: A method of coiling artificial silk threads
IPC: B65H54/54
Filed: 1930-07-03
Abstract: Artificial silk threads obtained by the parallel spinning process, are wound immediately after their passage through a precipitating bath on a winding device of variable diameter so as to produce a cheese which is adapted to be subjected in this form to further treatment by liquids.  For this purpose, the diameter of the winding device is reduced after winding so as to form a hollow space between the coil and the device permitting the coil to be slid off the latter without damaging the inner layers of the threads.  The thread may be wound in crossed windings to produce a coil cylindrical from end to end without tapered end portions. After removal from the winding device, the cheese may be mounted on another spool and then treated with washing, desulphurizing, bleaching, or other liquids, or it may be treated with liquids while unsupported.  Reference has been directed by the Comptroller to Specification 307,357, [Class 2 (ii), Cellulose, &c.].
