Patent GB-219918-A (GB)
Abstract: 219,918. Haddan, R., (American Type Founders Co.). May 9, 1923. Tripping-arrangements. - A platen press of the kind which is convertible for hand or automatic feed such as is described in Specification 219,758 is constructed with tripping means for throwing the machine off impression if a sheet is not fed to the suction separator, or if a sheet is not received correctly by the delivery grippers. The tripping means operates in conjunction with a hand-operated tripping means of known construction comprising a hand-operated lever 14, Fig. 1, which operates an eccentric 191 to trip the forme bed via lever-and-link mechanism 193 - - 199. Pivoted to the lever 14 is a head or guide member 210, Fig. 5, in which slides a link 225 reciprocated by the oscillating movement of the bed, the link 225 being formed with a slot and with a part of its end of reduced thickness so as to form a shoulder 228 capable of engaging the end of a plug 215 in a cylinder 213 connected to the head 210. Normally the plug 215 is withdrawn against the action of a spring by suction if the feed is working correctly, and a spring-controlled pivoted catch 221 holds the plug 215 in its withdrawn position until the shoulder 228 of the link 225 has moved passed the plug 215. The link 225 thus fails to operate the trip mechanism, and the catch 221 is then released by an inclined member 230 on the link so that the plug can be again moved out of operative position by suction. If the suction fails to withdraw the plug 215, the shoulder 228 of the link engages the plug and the lever 14 is thus moved by the link 225, and the eccentric 191 is operated to trip the forme bed. The trip is also operated by an electric feeler device, Fig. 8, arranged in connection with the delivery grippers of the press, which is so arranged that an electromagnet 233 is energized and operates a hook 231 to move the latch 221 to permit the plug 215 to engage, link 225 and so actuate the trip. When the trip is operated by either of the methods, a lever 260 on the shaft of one of the levers of the tripping mechanism operates an air release 240 by means of a link 247. The machine thus continues to be tripped until the cause of trouble is removed. The air release comprises a pivoted lever 245 which normally closes an outlet 242 in the vacuum circuit. When the lever 245 is moved by link 247, the outlet 242 connects to the atmosphere. The air release link 247 is normally connected to an arm of lever 245 by a spring catch 249 engaging a notch in the link, but the catch can be put out of operation by a chain 255 operated by a switch arm 256 or other member. After tripping has taken place a pin 236 on the link 225 restores the lever 14 to its normal position. When the machine is used with hand-feed, the automatic tripping mechanism is thrown out of action by withdrawing the plug 215 into the cylinder 213, and holding it there by means of a pin 281 operated by a nose 280 of a bell-crank lever actuated from a hand-grip 277 which is held by a ring to a link 276 on the hand-lever 14 when the press is to be controlled entirely by hand.

Title: Collector structure for an underwater mining system
IPC: E02F3/92
Filed: 1969-05-01
Abstract: 1,211,527. Underwater mining. WESTINGHOUSE ELECTRIC CORP. 1 May, 1969 [16 May, 1968], No. 22218/69. Heading E1F. A collector structure of a mining system for the mining of aggregates from a surface beneath water comprises a black means 50 for scraping aggregates from the surface, a cylindrical scoop 25 for carrying aggregates away from the blade, a hopper 70 positioned within the scoop to receive aggregates therefrom and means for rotating the scoop relative to the blade means and the hopper. The scoop, which is rotatably mounted in a towing yoke, consists of axially spaced rings 36 that engage the surface to cause rotation of the scoop as it is towed over the surface, and longitudinally extending trays 33 secured a regular intervals around the inner surfaces of the rings, the trays 33 being for the conveyance of aggregates between the blade and the hopper. The aggregates drop off the trays into the hopper and are deflected by inclined surfaces 97, 98 to the ends of the hopper for removal therefrom at 85 by a suction source. Mesh screens disposed radially inwards and outwards of the trays allow of escape therefrom of undersize aggregates. The blade means 50 involves double ended scraper teeth being so mounted on a carrier rotatable about the axis of the scoop as to extend down between the lower portions of the rings 36. The pivotable carrier and the double ended teeth ensure of continued scraping of the surface in the event of the structure overturning. The weight of the carrier can be varied to allow of varying of the depth of penetration of the teeth and rings into the surface. Sonic signalling means are appropriately mounted on the structure to provide an intermittent signal that is a function of the rate of rotation of the scoop and so provides at the surface of the water indication of the manner of operation of the structure on the submerged surface.

Abstract: 359,064. Refrigerating. NOLCKEN, W. G., 16, Redcliffe Gardens, Fulham Road, London. July 23, 1930, No. 22232. [Class 29.] Absorption systems; refrigerators.-Cabinets are cooled indirectly by extremely cold substances such as solid carbon dioxide and liquid air through a heat transfer system operating on the principle of absorption or adsorption refrigerating systems, the cold substance being used for cooling the condenser element of the refrigerating system. In the arrangement shown in Fig. 3, a continuous-cycle inert gas system is employed, comprising a generator G and evaporator C within the cabinet, a condenser A which may also be within the cabinet and is cooled by the carbon dioxide ice or other substance placed in a receptacle R, and an external absorber E cooled by air or water. Inert gas such as nitrogen circulates between the generator and condenser elements. The generator is heated only by the substances to be cooled,.and the mixture of evolved vapour and inert gas rise through a pipe J to the condenser A whence inert gas returns by a pipe K. Condensate flows from vessel A through a sealing pipe B to evaporator vessel C, which may communicate through thermostatically controlled valves W with one or more coils C<1>. The vapour from the evaporator flows by a pipe D into the liquor pipe H and serves to lift the liquor from the generator to the absorber level. Another arrangement comprises an absorber, a generator and a condenser working on an intermittent cycle, the cabinet being cooled when the vapour is generated from strong liquor and condensed. A heat transfer system employing siliea gel as adsorbent and sulphur dioxide as refrigerant comprises a condenser-evaporator element A, Fig. 5, cooled by the cold substance, and a generator-adsorber vessel E. The heat of the cabinet is transferred to the vessel E by closed system K containing a volatile medium and an inert gas, and the vessel E is cooled during the adsorption phase by a similar closed system J having an external part exposed to the atmosphere or other cooling medium. The cabinet may be cooled in part by the cold substance itself by heat transfer through the condenser walls.
