Abstract: In a process for the production of linear segmented polyurethane by simultaneous reaction of macrodiols, low-molecular diols as chain-lengthener and aromatic diisocyanate, in a solvent in the presence of catalyst, and in the presence of catalytic amounts of a magnesium or calcium salt, an aromatic carboxylic acid macrodiol, monomeric, lower-molecular diol and aromatic diisocyanate are reacted, the macrodiol being used in such amounts as to adjust in the prepared polyurethane a weight ratio of soft segment to hard segment of about 4:1 to 1:4. Preferred embodiments include reaction at temperature from about 70 DEG  to 120 DEG  C.; use of an inert solvent; and having the concentration of starting material amount to about 10-40% by weight relative to the mixture of starting material and solvent. Also provided are polyurethanes obtained according to this process, having a molecular non-uniformity from 2 to 7. Preferred embodiments include that the polyurethane have an average molecular weight from 60,000 to 250,000. The polyurethanes are useful for the production of membranes, specifically those to be used for sterile filtration or blood oxygenation.

Abstract: Hardmetal lamina (15) are cut, by a process known as electrical discharge machining, from a block of hardmetal (10) using a wire electrode (12). The laminae so formed may then be attached by adhesive or epoxy resin to a suitable base (16) in order to form a hard metal surfaced tool. Provision is made for preventing this hardmetal from shearing from its mounting, and also to remove any heat generated within the hardmetal. Reference is made especially to using the above construction for a 'slipper' within a tile producing machine. The word 'hardmetal' is used to denote powdered carbides of the transition metals, cemented into solid masses by a matrix of a metal of a lower melting point.

Abstract: An actuator for controlling the brakes of railway vehicles comprises a tubular casing (18) in which is slidable a piston (26) carrying a hollow shaft (28) in which a rod (34) for operating the brake means is coupled axially. The rod is threaded externally and an annular threaded stop member (36) is engaged thereon, having a frontal coupling part (40) which cooperates with a complementary frontal coupling part (42) of the hollow shaft (28). An annular friction member (50) is interposed between the casing and the threaded rod to allow axial sliding of the latter relative to the hollow shaft so as to take up play due to wear of the brake means. Manually operable releasing means (100) are connected to the free end of the rod for freeing the rod itself for rotation. The actuator may be provided with a spring-operated device (110, 112, 115) for parking or emergency braking.

Abstract: Logic circuits based on a differential amplifier with the common emitters thereof being connected through a constant current source generally require the use of a reference voltage (Vr) and associated transistor for each such differential amplifier to provide the reference level against which the two inputs (A, B) are compared to obtain the necessary logic operations. 
<??>In order to eliminate the requirement for the reference voltage and the transistor, the input signals (A, B-) are selected to have the same relative amplitude difference (VL) between the high and low levels thereof and one of the two input signals is further controlled to be shifted relative to the other one by an amount equal to 1/2 such selected amplifier difference. The differential amplifier (42, 44) has a constant current source (50) and the respective output circuits (56, 66) are connected in emitter-follower configuration having constant current source resistors (60, 70) across which the output voltages are taken. By selecting the relative resistor values, the desired shift (1/2 VL) of the relative output level can be obtained. By employing additional sets of transistors in the differential amplifier, multiple inputs are accommodated and by utilizing output circuits having selected resistor value relationships, corresponding multiple outputs are obtained.
