Abstract: The invention relates to a ventilation device for the loading space of closed railway goods wagons having side walls consisting essentially of sliding wall parts. In this type of goods wagon, the ventilation devices usually arranged in the side walls cannot be used due to the low constructional height of the sliding wall part. The object of the invention is to find a suitable, economically manufacturable ventilation device for these goods wagons. According to the invention, the ventilation opening in the end wall of the railway goods wagon is arranged between two vertical end wall columns near to the top end of the end wall, a cover being provided at a distance in front of the ventilation opening, which cover engages above the ventilation opening in a labyrinth-like manner in the end wall. The ventilation opening can be closed by a slide by means of a linkage which can be actuated from the track level. <IMAGE>

Abstract: 57 A thermostatic control unit 13 has a back-up battery 23, for a clock 24, requiring a small current to maintain the circuit active during the open cycle of the thermostat switch 20. The control unit 13 is connected in series with an operating unit 11, which has a coil 30 and contacts 31 which operate a furnace (not shown). A positive temperature coefficient (PTC) resistor 32 ist placed in parallel with the coil 30 to provide a low input impedance for maintaining the small current without activating the coil 30. During the operation of the thermostat 15 with the switch 20 closed, a larger current to the PTC resistor 32 causes the resistor to increase in temperature and thus its impedance; so the wattage dissipated by the PTC resistor 32 is reduced to minimize the heat dissipation and thus the temperature of the operating unit 11.

Abstract: An implantable valve for controlling the passage of cerebrospinal fluid (CSF) from a ventricle of the brain to a suitable drainage location in the body includes a movable diaphragm which positions a valve seat in response to the pressure differential between the inlet and outlet of the valve. The valve seat defines a fluid orifice. An improved valve stem, preferably of one-piece construction, and provided with a series of cooperating diverging and converging frusto-conical portions, extends through the orifice to provide four stages or conditions of fluid flow and pressure control in response to relative movement between the valve seat and stem. In a first stage or condition of operation of the valve, wherein the fluid pressure differential falls below a threshold level, fluid flow is prevented. In a second stage, sufficient fluid flow is permitted to maintain a first substantially constant predetermined differential pressure. In a third stage, fluid flow through the valve is maintained at a substantially constant rate, and in a fourth stage sufficient fluid flow is permitted to maintain a second substantially constant predetermined differential pressure.

Abstract: Native collagen is reacted with a di or tri-carboxylic acid halide, di or tri-sulfonyl halide, di or tri-anhydride, or di or tri-reactive active ester coupling agent to produce a chemically-modified collagen compound wherein one or more native collagen molecules are coupled at at least one lysine epsilon amino group by a discarbonyl, tricarbonyl, disulfonyl or tri- sulfonyl coupling group, or a coupling group having a plurality of moieties, at least two of which are carbonyl or sulfonyl groups. The reaction is done in a controlled manner so that the degree of cross-linking is limited. Any remaining lysine epsilon amino groups present in the coupled collagen product may be converted to carboxyamido or sulfonamido groups by acid halide, anhydride. sulfonyl halide or active ester amine-modifying agents. The resultant product when dissolved in a physiological buffer provides a viscoelastic solution having therapeutic application in a variety of surgical procedures, particularly in ophthalmic surgery. This viscoelastic solution "melts", i.e., exhibits a dramatic loss of viscosity, when subjected to temperatures of between 32 and 48°C.
