摘要： Apparatus for the oral administration of capsules to animals, particularly ruminants such as sheep, comprises a tubular member adapted to be inserted into the animal's mouth so that the tip of the tubular member is near the root of the animal's tongue, means for introducing a capsule into the tubular member and for propelling the capsule to its tip, in which the tip of the tubular member consists of two tip portions extending from the mouth of the tubular member and laterally spaced from one another so as to define a cavity in which a capsule is deposited at the root of the animal's tongue. The top of the tubular member has a convexly curved upper surface adapted to engage the animal's soft palate to encourage a swallowing reaction, and a lower surface shaped to engage and restrain movement of the dorsum and the front part of the animal's tongue. Apparatus is disclosed in which the means for propelling the capsule along the tubular member comprises means for supplying air or gas under pressure to the tubular member. The use of gas to propel the capsule ensures that it is adminstered rapidly with no risk of damage to the animal.

摘要： A typewriter carriage escapement mechanism comprises a rack (10) movable with the typewriter carriage (2) and having two sets of teeth (16 and 18) projecting in opposite directions. An escapement dog (30) has two separate teeth or sets of teeth (44 and 54) arranged to engage the two sets of rack teeth (16 and 18) alternately as the dog (30) moves at right angles to the rack (10), on operation of the keys (90) or space bar (92) of the typewriter. One of the sets of teeth (54) is mounted on a pawl (50) movable relative to the other tooth (44) or set of teeth, to enable both sets of teeth to be disengaged from the rack (10) to release the carriage (2). The pawl (50) is movable against a return spring (70) by means of an actuating rod (80) engaging a lug (62) on the pawl (50). The mechanism of the invention enables a single escapement member (30) to effect both the stepwise movement of the carriage (2) and also the carriage release. The elements of the mechanism need only to be reciprocated in a straight line, so simplifying the construction of the mechanism.

摘要： A mine roof support has a roof engaging structure 13 and a floor engaging base 14, spaced apart by extensible hydraulic jack means 15 and 16. The roof engaging structure and the base are interconnected by a pivotal linkage device 23, 24 arranged so that, throughout its range of working movement, a pivot point of the linkage performs substantially greater movement in the vertical direction than in the horizontal direction. This reduces the effect of problems arising from the linkage device projecting substantially into the goaf area of a mine working or into the walkway area of the support. In a preferred embodiment the linkage device comprises a parallelogram type linkage.

摘要： A valve device is provided for use in a pressurized hydraulic fluid path, for example the hydraulic path of a hydraulic leg of a mine roof support which is required to yield under two different sets of conditions. The valve device has a port 15 for connection to the pressurized hydraulic fluid path, a bleed valve 25 being arranged to permit hydraulic fluid to bleed from the path at a first rate when the pressure in the path exceeds the first limit, for example to permit the hydraulic leg to collapse at a very slow rate, for example as a mine roof converges. There is also a dump valve 20 arranged to permit hydraulic fluid to flow from the path at a second greater rate, for example if a rock burst occurs. Although the dump valve 20 reacts to high pressure surges of fluid, it does not react to low pressure surges because a non-return valve device 30 traps on one side of the dump valve hydraulic fluid which is at a pressure in the region of the first limit. Thus the dump valve only operates if the pressure on the other side of the dump valve exceeds the first limit.

摘要： An underground support, e.g. for the roof of a mine, has a roof engaging canopy 10 which can be raised and lowered in a controlled manner by hydraulic legs 14. Inflatable flexible membrane means, for example in the form of bags 12, are provided on the upper face of the canopy 10, which shape themselves to the mine roof and distribute loading evenly thereto. Inflatable flexible membrane means may also be used to prevent flushing of loose debris between adjacent supports, and on roadway supports.

摘要： A coal cutting machine 13, a conveyor 12 and a plurality of mine roof supports 10 extend along the face 11 of a coal mine. The operation of the hydraulic jacks of the roof supports are controlled by pilot valves which are electrically powered and rotationally driven. For example, motorized or cam operated pilot valves can be used. Such pilot valves use much less energy than valves controlled conventionally by solenoids, and the electricity supply can thus be at an intrinsically safe level.The operation of the pilot valves include unitary operation of a given support, remote operation of one support from another and sequential operation of a series of supports. When the system controls a plurality of supports sequentially, sensing means sensitive to a first pressure level in a first support when the first support is set to a mine roof activate another support in the sequence when the first pressure level has been sensed in the first support, while continuing the raising of the pressure in the first support until a second, higher pressure level is detected.A group of supports is controlled by a control station positioned at a face end, and in addition each support has its own individual control position. The control station incorporates a microprocessor which may be reprogrammed underground.
