Abstract: A flexible ocular insert device adapted for the controlled sustained release of an ophthalmic drug into the eye, wherein the device includes an elongated cylindrical shaped body having a length of at least 8 mm and with the diameter of its body portion not exceeding 1.9 mm. The sustained release mechanism may be by diffusion or by osmosis or bioerosion. The insert device is advantageously inserted into the upper or lower fornix of the eye so as to be independent of movement of the eye by virtue of the fornix anatomy. In one embodiment of the invention, an insert device having a length of 8 to 25 mm, to suit eyes of different sizes, was employed for use in the lower fornix and a device having a length of 8 to 35 mm was employed for use in the upper fornix. The present insert device is of a size and configuration such that, upon insertion into the upper or lower fornix, the device remains out of the field of vision so as to be well retained in place and imperceptible by a patient over a prolonged period of use.

Abstract: The laser beam levelling device has a vessel (1) with a U-shaped cross section filled with a dark liquid. A respective photoelectric sensor (2) is located on the exterior of the two free arms of the U. The two sensors (2) are connected to an evaluating device (3). As a respective light source (4) is provided opposite the sensors (2), a clear bright/dark distinction emerges in the region of the liquid surface level. This transition from the dark part into the bright part therefore indicates exactly the height of the liquid level. By comparing the height of the liquid level in the two arms of the U, the inclination of the axis X-X can be calculated in the evaluating device (3), or it can be determined whether the vessel (1) is located in the horizontal. The respective inclination can therefore be defined with high precision. The laser beam levelling device can accordingly be erected on a site on any uneven ground.

Abstract: A gate lifter for shifting a gate from a valve seat in a gate valve. The gate lifter is provided on the downstream, or low pressure side of a valve, and is a tubular structure that surrounds and is slidable relative to a tubular valve seat. Hydraulic or other pressurized fluid is adapted to be introduced between an end of the lifter and a flange carried by the valve seat to cause the parts to move in opposite directions, as a result of which the lifter operates by shifting the gate member away from the valve seat to avoid damage to the valve seat as the gate member is moved there across. The gate lifter includes a face that is adapted to engage with a corresponding face of the gate member, the gate lifter face preferably including a low friction coating, such as teflon, gearings or gearing type material.

Abstract: A racing game utilizing a game board which simulates an auto race course is disclosed. In one embodiment, the invention relates to a board game which provides features similar to a NASCAR auto race. Each player receives a racing car game piece and a crew chip. Upon spinning the dial during the player's turn, the player places his crew chip on the board space corresponding to the spin number and then takes a card from either of two stacks depending on the color of the space occupied by the crew chip. If the player answers correctly the question on the card, he moves his game piece to the space occupied by the crew chip and removes the crew chip. If he answers incorrectly, the crew chip is withdrawn and the game piece remains in the position occupied at the beginning of the turn. Play continues as the game pieces are moved around the board with bonus points and penalties being received depending on the space occupied by the player during the course of the game.

Abstract: A method and a machine for cutting a nape muscle of a fish from a front-part of a fish, after the fish has been parted, and removing the fish skin from the nape muscle. The method includes moving the front part along a fixed, straight track to and past vertical circular knives which cut vertical cuts at each side of the spinal crest and at the same time to and past horizontal fixed knife blade edges, fixed on the leading portion of a plough structure, which in turn is fixed to the shaft mount for the shaft of the circular knives. The plough structure cuts lateral cuts from the spine to the skin, but not through the skin. The outermost side part of the plough structure, the plough spade, is not sharp and is used to tear the nape muscle from the attached skin, when the skin is pulled forwards through a gap formed between the plough spade and a sliding table below the plough structure, the nape muscle being retained at the upper surface of the plough structure.
