Title: Improvements in or relating to the blasting of ore, rock, overburden and the like
IPC: F42D1/00
Filed: 1956-01-16
Abstract: 778,760. Blasting rock and charges therefor. MAUMEE COLLIERIES CO. Jan. 16, 1956 [Jan. 26, 1955], No. 1456/56. Classes 9 (1) and 68 (1). To blast rock, instead of lowering waterproof bags nlled with ammonium nitrate explosive into a vertical shothole as in Specifications 767,860 and 776,810, a bag 7 of resilient, waterproof, plastic material such as polyethylene is lowered into the hole, the bag being long enough to line the hole, and granular ammonium nitrate is then poured into the bag. Furthermore primer cartridges, which may be as in Specification 776,108 are placed in the bag, so that no point in the blasting charge 6 is more than 4.6 to 10.7 ins. from a primer 4. A tamper 12 is used to ram charge 6 into the bag and so eliminate air spaces. To lower the bag into the hole, a weight 11 or a cartridge of granular explosive is placed in the bottom of the bag 7, the mouth of the bag being held in the open end of the hole 1 by a funnel which has a locating shoulder 10. The ammonium nitrate after being mixed with finely divided combustible material, e.g. carbon black, in a rotary mixer (not shown) descends through a spout 14 into the bag and flows around the tamper. A fuze cord 5 connected to the primer 4 may be replaced by a blasting cap. When sufficient explosive has been charged into the bag, stemming material is introduced. This material may be placed directly on top of the explosive or the bag may be wrapped around the fuze cord and the tamping poured on to the bag. In an alternative method for shot-holes, which are burned into the ore then enlarged by " springing", plastic bags containing the granular explosive are dropped at intervals into the bag 7, so that these bags spread and compress the explosive poured into the bag 7.

Filed: 1947-01-23
Abstract: 620,617. Lifting-dogs. ROADS, H. C. Jan. 23, 1947, No. 2139. [Class 78 (iv)] Apparatus for lifting sacks, bales or the like comprises a carrier for attachment to a hoisting rope or cable provided with a pair of horizontally-spaced blocks, a pair of jaw members pivoted together intermediately of their length and slidably supported by the blocks in such a way that the upper limb of the right-hand jaw member has contact with the left-hand block and the upper limb of the left-hand jaw member has contact with the right-hand block, the block-contacting surfaces of said jaw limbs being inclined to the vertical in upwardly diverging directions so that when the jaw members freely depend from the carrier, the upper limbs of the jaw members ride upon the blocks which constrain the jaw members to close, while when the carrier is lowered relative to the jaw members, the upper limbs of the jaw members separate to open the jaw members. In the embodiment shown, jaw members 10, 11, pivotally connected at 12, are slidably supported in a carrier 13 suspended by a shackle 20 from a hoisting cable. The carrier comprises a pair of plates 14 spaced apart by cylindrical blocks 15, 16 and a block 17 and secured together by bolts 18. The links 23, 24 of the jaw members normally rest against the blocks 15, 16 with a clearance between them and the block 17. When a .sack is to be lifted, the carrier is lowered so that the jaw members contact the sack and the block 17 engages these jaw members to assist their opening. The latter are now manipulated to engage the sack and the carrier pulled up by the hoisting rope whereby the jaw members will be closed by the blocks 15, 16 sliding along their limbs 23, 24.

Title: Internal combustion engine with a fuel-injection pump and a pneumatic regulator
IPC: F02D1/06
Filed: 1976-01-21
Abstract: 1530962 Regulating fuel injection DAIMLERBENZ AG 21 Jan 1976 [22 Jan 1975] 02339/76 Heading F1B The control rack of a fuel injection pump is positioned by a vacuum operated diaphragm subject on one side to the pressure downstream of an air throttle valve, the vacuum being controlled so that it is always proportional to the deviation of the operator's control from the rest position. Control rod 13 is biased towards a position in which larger fuel quantities are injected, by spring 16 and is moved against the spring by diaphragm 15 when negative pressure prevails in capsule 14, which is connected by conduit 31 to air intake passage 5. Throttle plate 20 is guided axially by rod 18 and is moved by the dynamic pressure of the air stream against spring 21. A cone 24 forms the abutment for spring 21 and its movement is regulated by operator's pedal 10, which can rotate through an angle "α". Spring 21 has a constant rate and is a weaker spring than return spring 28 of pedal 10. Dynamic air pressure at idling speed of the engine is insufficient to displace throttle plate 20 against spring 21. To prevent irregular running at low speeds, throttle plate 20 is coupled to spring 21 through ring 28a, pins 29, cross-member 28b and spring 30, the latter spring being initially stressed less than spring 21 but having a higher rate, so that under no-load conditions the plate 20 can yield slightly, but at higher engine speeds the force due to spring 21 is less than that due to spring 30 and the elastic coupling between plate 20 and ring 28a is inoperative. In a modification the plate 20 is pivotally mounted about one edge and tends to be rotated against the direction of the air stream by a first spring, the action of which is opposed by a second spring which is connected to the accelerator pedal so that the force applied by the second spring is dependant on the throttle pedal position.
