Title: Shredding or crushing device
IPC: B02C18/00
Filed: 1949-05-17
Abstract: 665,177. Crushing mill. SOC. DE MATERIELS INDUSTRIELS ET AGRICOLES DE RAPAGE G.U.I.R.A.P . May 17, 1949 '[May 19, 1948], No. 13158/49. Class 59 [Also in Groups I, VIII and IX] Material is shredded or crushed by passing it between two chain surfaces. As shown, two chain surfaces moving at relatively different speeds encircle drums 9, 11 and 10, 12, respectively, the chains being formed of articulated blocks 1 comprising saw-toothed blades 2 and interblades 3. The blocks are mounted on spindles 4 locked by bolts 5 and are interconnected by spindles 6 'guided in their horizontal course by guides 7, 8, rotation of the chain surfaces being effected by interengagement of the spindles 6 with toothed spiders of driving drums 9, 10, and driven drums 11, 12. The chain assemblies are staggered thereby leaving a free working surface on drum 10 for the transportation and forcing of material into the shredding or crushing zone. Material from a hopper in the region of 13 may be pre-crushed by a shoe &c. being placed in proximity to the arrow 15. The shredding or crushing surfaces may be inclined to one another and curvilineal surfaces may be obtained by giving the appropriate form to guides 7, 8. The axes of drums 9, 10, 11, 12 may be resiliently mounted and may be adjustable to vary the space between the operating surfaces. The apparatus may comprise two drums, each of which is provided with chains or the shredding or crushing may be effected between a chain surface similar to that already described, and a drum provided with chains. The apparatus may function as a fulling device in which case the speed of the two chain surfaces would be equal. According to the Specification as open to inspection under Sect. 91, the apparatus may be used for cider and comestible oil manufacture, the reduction and pulverizing of waste paper, the unravelling of rags and similar material, the reduction and mincing of oil cake, dry fodder, straw, chicory &c. and the shredding of fish and meat. It is also stated that the blades may be transversely arranged, not longitudinally as shown, and that the teeth may be replaced by abrasive surface elements. This subject-matter does not, however, appear in the Specification as accepted.

Abstract: 833,904. Wells. CAMERON IRON WORKS Inc. April 28, 1958, No. 13382/58. Class 85 In a blowout preventer comprising a bore 19, bores 21 normal to the bore 19, and rams 16 reciprocable in the bores 19 each of the rams is formed by elements 18 movable longitudinally relative to each other. Each ram comprises a body 20 moved by rotation of a handwheel 11 and on which the elements 18 are slidably mounted. Pistons 27 attached to each element separate a chamber 24 from a chamber 25, each chamber being filled with liquid. The elements have resilient inserts 41. In the modification shown in Fig. 7, a valve 57 is arranged so that a pump 58 supplies liquid at pressure to one side of all the pistons and at the same time removes liquid from the other sides, each at the bores 49 containing the pistons being connected to adjacent bores at their ends. In a further modification (Fig. 8) each ram element 74 has a flange 75 sliding within a slot 73 in the ram body 66, the spaces between the elements and the walls of the slot being filled with steel balls 77 surrounded by flexible envelopes 76, 78. The balls act like a liquid, and in a modification may be replaced by granular material without envelopes. A passage 79 permits well fluid to exert a closing pressure on the rams.

Abstract: 544,549. Administering anaesthetics. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Aug. 26, 1940, No. 13459. Convention date, Aug. 24, 1939. [Class 81 (ii)] An appliance for supplying anaesthetic gas in a predetermined quantity followed by a second quantity sufficient to maintain the analgesia includes an expansible feed chamber 20 connected to a device sensitive to change in volume of the chamber and adapted to operate a valve 31 to admit air or oxygen to the gas being administered. In the form shown, decrease in volume of the chamber 20 causes pivotal movement of an inverted U-shape member 8 supporting a cam 28, such movement causing vertical movement of a tappet 29 connected to the valve 31. Upon emptying of the chamber 20, the supply of gas is cut off from the patient for a predetermined period of time dependent upon the amount of opening of a throttle valve 7. In a modification, operation of the valve 31 is obtained by connecting the tappet 29 to a lever supporting a weighted cord. Upon decrease in volume of the chamber, the weight can fall, to rotate the lever and open the valve 31. Specification 511,559 is referred to.
