IPC: E21B11/04
Filed: 1953-11-19
Abstract: 728,491. Boring grabs; opening and closing mechanism. SOC. FRANCAISE DE CONSTRUCTION DE BENNES AUTOMATIQUES. Nov. 19, 1953, No. 32076/53. Class 78 (4). Boring apparatus, suitable as a boring tool for breaking up the ground and as a grab for removing the broken-up material, comprises a substantially cylindrical member 1 having grab scoops 7 pivoted to the lower end thereof, which scoops 7 are held in the open position by the wedge end of a locking rod 46. The cylindrical member 1 is suspended from a chain 31 and contains therein a movable block 11 which actuates the grab scoops 7. There is a lost-motion connection, between the rod 46 and a cylinder 14 secured to the block 11, comprising a pin 15 and a slot in the rod 46. A cable 32, secured to the end of the chain 31, passes round a lower set of pulleys 33, carried by a case 42 secured to the rod 46, and an upper set of pulleys 34 mounted towards the top of the cylinder 1, and its end is secured to an eye 35 adjustably mounted in the cylinder head 4. A spring 22 is disposed between the top portion of the cylinder 1 and the top of the block 11, and a lighter spring 43 acts between the block 11 and the top of the case 42. A spring-pressed slide 56 is mounted in the head of the cylinder, and means are provided for locking it in position. When, as shown in Fig. 1, the boring apparatus is in position for continuously acting as a boring tool, it is suspended from the chain 31 solely by means of a link plate 82 in the chain engaging pawls 60 pivotally mounted on the top of the cylindrical member 1. In order to close the grab, slack is given to the chain 31 whereby the downward movement of the link plate 82 allows the pawls 60 to tilt under the action of the spring-pressed slide 56. The chain is then wound up, the link plate 82 now being free to pass through the slide 56, and the movement transmitted to the cable 32 raises the case 42. The locking rod 46 rises and the spring 43 becomes compressed. Further upward movement of the cable takes up the lost motion between the block and rod 46, and the scoops close. The spring 22 also becomes compressed. The sleeve 65 may engage a locking ring from which the apparatus becomes suspended. If slack is then given to the cable 32, the spring 22 expands and causes the scoops 7 to open and empty the contents of the grab.

Title: The manufacture and use of new organic compounds
Filed: 1932-11-14
Abstract: Organic condensation products which are methylene ethers are obtained by condensing formaldehyde or a polymer thereof or a substance yielding formaldehyde with a polyhydric alcohol. Examples of polyhydric alcohols are glycols, particularly propylene glycol, diethylene glycol, and alcohols containing more than two hydroxy groups, for example, glycerol and glycerol monochlorhydrin. Formaldehyde may be replaced by formalin, trihydroxymethylene, para-formaldehyde, or hexamethylenetetramine. In examples, (1) glycerol or polyglycerol, and formalin, trihydroxymethylene, or para-formaldehyde are distilled under a reflux condenser in the presence of hydrochloric acid; (2) ethylene glycol is condensed with formaldehyde or its polymer in the presence of hydrochloric acid; (3) propylene glycol is condensed with para-formaldehyde in the presence of hydrochloric acid; (4) glycerol monochlorhydrin is condensed with para-formaldehyde in the presence of hydrochloric acid; (5) diethylene glycol is condensed with para-formaldehyde in the presence of hydrochloric acid.  The products obtained are good solvents for cellulose esters and ethers, and for other lacquer bases, e.g. polymerized vinyl compounds and other natural and synthetic resins, and are of value in the production of liquid and solid compositions and articles, such as films containing such lacquer bases, and in stretching, shrinking, delustring and other after-treatment processes such as are referred to in Specifications 392,186 and 395,353.  The solvents may be employed for causing thin foils of acetone-soluble cellulose acetate to adhere to paper, photographs, prints, woven fabrics, pasteboard, wood, glass, metals and the like.  In all the above applications, other solvents may be used in conjunction with the methylene ethers, e.g. acetone, ethylene dichloride, ethyl lactate, tetrachlorethane, and diacetone alcohol, as well as plasticizers such as diphenylol propane, triacetin, dibutyl tartrate, diethyl phthalate, monomethyl xylene sulphonamide, and triphenyl phosphate.
