Abstract: A computer system for preventing copying or duplication of a program which has a CPU (2), a ROM (15), a RAM (18), an FDD unit (4), a loader program executed by the CPU (2) for loading the program from the FDD unit (4) to the memory (18), an address selector switch (21), and an FM/MFM modulating circuit (20). The CPU (2) reads the program from the FDD unit (4) to the RAM (18) under the control of a control program stored in the ROM (15), the program being stored in the FDD unit (4) in the MFM mode which does not allow readout of the program by the loader program. The readout program is modified by the FM/MFM modulating circuit (20) in accordance with a machine number unique to the machine and read from the address selector switch (21). The modified program is written in the FDD unit (4) by the FM/MFM modulating circuit (20).

Abstract: @ A heat exchanger such as a vehicle radiator comprises a pair of tube plates 11,12 between which flat tubes 13 extend, interspersed with corrugated fins forming airways 14. Header tanks are formed by attaching shells (not shown) to the tube plates. In production of the radiator, the tubes and airways are assembled, between clamping channels 17, as a separate item. To hold the matrix together, ties 16 hold the clamping channels together. The ties have end portions 17 which are bent laterally with respect to the axes of the ties, and which extend in different, preferably substantially opposite directions. Thus the ties can only be removed from the apertures in the channels by twisting the ties about their axes, and thus cannot jump out as a result of vibration.

Abstract: A slewing crane with a telescopic tower has two hinged bracing stays in the area of the tower top. A rear bracing rope runs via the outer fixed points of the bracing stays to a bottom fixed point. Fastened to the outer end of the centre bracing stay hinged in the area of the tower top are two further bracing ropes of which one is fastened in the area of the articulated connection of the support parts and the other runs via a fixed point at the outer end of a bracing stay hinged in the area between the support parts to a fixed point at the outer support part. So that the crane can be set up and assembled without additional assembly devices, the trolley travelling rope (9) runs over a rope pulley (10) arranged in the area of the tower top and is then run via rope pulleys (11, 12, 13) in each case in the area of the outer end of the bracing stay (22) hinged in the area of the articulated connection (25) of the support parts (23, 24) and in the area of the outer end of the outer support part (24) to a return rope pulley (14) at the trolley (20). From the latter, it runs via rope pulleys (12', 11') mounted parallel to the two rope pulleys (12, 11) of the outer support part (24) and the bracing stay (22) back to a rope pulley (15) mounted at the inner end area of the inner support part (23) or at the tower top. The rope returned around this rope pulley (15) is reeved between the bottom block (16) and the top block (17) of a block and tackle (18) and is anchored to a fixed point of one of the blocks (17).

Abstract: An extended impulse response characterisitic is obtained by connecting a plurality of adaptive filters (101) or echo cancelers in a tandem connection. Delay units (102) are associated with receive inputs (X) of the adaptive filters or echo cancelers so that each filter or canceler models a predetermined fixed portion of the extended impulse response characteristic. The relative positions of the filters or cancelers in the tandem connection are controllably switched [via 103-0 to 103-(N-1) and (104)] at a predetermined rate (via 105) to ensure so-called 'good' adaptation of the individual adaptive filters or echo cancelers. The adaptive filter or echo canceler in a preferred position in the tandem connection may be allowed to adapt at its normal rate while the other filters or cancelers are inhibited (via INH) from adapting, or are allowed to adapt at slower rates dependent on their relative positions in the tandem connection.

Abstract: A converted digital signal is provided in NRZI code with a dc component of zero and with a maximum number of four bits between level transitions in the signal. The base digital signal is divided into 8-bit base words, each of which is then converted into a 10-bit converted word to form a converted digital signal suitable for recording. Of the 1024 (2'°) possible 10-bit combinations, there are 193 that begin with no more than two digital zeros, end with no more than one digital zero, have no more than three consecutive digital zeros anywhere else and have a dc component of zero when NRZI-coded. Each of these 193 primary 10-bit combinations is used to represent one 8-bit base word. Each remaining 63 of the total 256 (2<sup>8</sup>) base words is converted into a secondary 10-bit combination which has a "convention" dc component of +2 or -2, defined as the dc component when the combination is NRZI-coded and the preceding combination ends at the signal's lower level, but which otherwise meets the description of the 193 primary 10-bit combinations. Beginning with the first bit of one secondary combination, the number of level transitions in the converted digital signal, when NRZI- coded, are detected up to the end of the 10-bit combination immediately preceding the next secondary combination. Depending on the number of level changes, the first bit of the next secondary combination is provided to give that secondary combination a convention dc component which eliminates the actual dc component in the portion of the signal containing the pair of secondary combinations.

Abstract: The viability of a pack of stored blood platelets is monitored by gripping the pack between two plates (6) and (7) which are closed to pinch together the walls of the bag (10) along an L-shaped seal (14), leaving a channel (17), squeezing a part (15) of the bag by means of a reciprocating plunger (19), so that the platelets continually flow to and fro between the part (15) and the part (16), through the channel (17), and passing a beam of light from an LED (27) through the channel (17), to a photoresistor (29). The AC signal from the photoresistor corresponds to the fluctuations in the intensity of the light passing through the channel (17) and the amplitude of this signal is representative of the viability, and hence the clinical acceptability, of the platelets.
