Abstract: METHOD AND DEVICE FOR DISCRIMINATING DIFFERENCE FREQUENCY     OF TWO PULSE TRAINS              Abstract of the Disclosure The proposed method for discriminating the difference frequency of two pulse trains resides in the following. The pulses of one train are separated into odd and even puls-es, while in the second train every second pulse is separa-ted. Then, every second pulse is checked for coincidence with even or odd pulses and, once such a coincidence occurs, the next check is for coincidence with, respectively, odd or even pulses, the frequency of such coincidences being representative of the difference frequency.  The proposed device for discriminating the difference frequency of two pulse trains by the above method comprises a means for comparing one train with the other, which means includes a separator of even and odd pulses, whose input serves as one of the inputs of the device. The comparison means also includes two AND gates having their first inputs connected to the outputs of the separator, an OR gate having its inputs coupled to the outputs of the two AND gates, an additional AND gate whose output serves as an output of the device and whose first input is connected to the OR gate, a two-to-one pulse frequency divider whose input serves as the other input of the device and whose output is connected to the second input of the OR gate, and a flip-flop connected to the output of the additional AND gate and having its outputs connected to the second inputs of the first two AND gates, the outputs of the flip-flop serving as the other outputs of the device.

Abstract: ABSTRACT OF THE DISCLOSURE   A printing apparatus has a holder which incorporates a permanent magnet and has a printing element or elements containing magnetically soft material.   In use a printing element is held against a thin positioning portion by the attraction of the permanent magnet.  To engage a printing element the printing element is placed in contact with the positioning portion and the permanent magnet is brought up to the positioning portion.  To release a printing element the permanent magnet is moved away from the positioning portion.   Printing elements may be aligned printing-face down in an aligning member. The printing elements have depicted on the face opposite the printing surface the character on the printing surface.   In one version a printing apparatus is used as a hand-stamp, and in another version a printing apparatus is inked and used by hand-rolling.

Abstract: ABSTRACT           Secure hardware is provided for cryptographically generating a verification pattern which is a function of a potential computer user's identity number, the potential computer user's separately entered pass-word, and a stored test pattern.  The test pattern for each authorised computer user is generated at a time when the physical security of the central computer and its data can be assured, such as in a physically guarded environment with no teleprocessing facilities operating.  Secure hardware for generating verifica-tion patterns during authentication processing and for generating test patterns during the secure run is disclosed which uses a variation of the host computer master key to reduce risk of compromise of total system security.  The use of a variant of the host master key prevents system programmers and/or computer operators from compromising the integrity of the authentication data base by, for example, interchanging entries and/or inserting new entries.

Abstract: SHARED SYNCHRONOUS MEMORY                   MULTIPROCESSING ARRANGEMENT     Abstract A multiprocessor system is described which allows for the sharing of memories between the individual processors having synchronous memory interfaces.  Three processing units are shown by way of example, each processor having its own local, associated memory.  Two of the processing units can each access its own memory but not any other memory.  The third processing unit can access its own memory as well as the memories associated with the other two processing units. A processor interface adapter interconnects the I/O busses of the processing units.  The functions performed by the processor interface adapter can be divided into two princi-pal groups.  The first group of functions permits communica-tion between the processors via their I/O busses.  The second group of functions permits the aforedescribed sharing of the memory units between the processing units.

Abstract: ABSTRACT                  COIN DISPENSER         The invention relates to a coin dispenser for use in vending machines for giving out change when the value of money inserted into the machine exceeds the price of the merchandise purchased.  The aim of the invention is to simplify the design of such a dispenser so that different sets of coins can be catered for from a small range of parts.        The dispenser comprises vertical coin tubes (12,13,14), one for each denomination of coin dispensed, and respective channels (15,16,17) extending horizontally beneath each tube.  Each channel has an aperture (21,22,23) in its lower wall offset from the axis of the tube, (12,13,14) and an apertured slide plate (24,25,26) is movable in the channel (15,16,17) from below the coin tube (12,13,14) to over the aperture (21,22,23) in the lower wall so as to dispense the coins singly from the stacks in the coin tubes.        The coin tubes extend down through apertures (18,19,20) in the upper wall of their respective channels so that the lower end of the tubes are the lowest point in the coin channels.  With this arrangement a range of denominations of coins of differing thicknesses can be catered for by setting the lower end of the tube at a height appropriate to the thickness of the denomination of coins during assembly.

Abstract: ABSTRACT          Apparatus for using focused solar radiation to gasify coal and other carbonaceous materials.  Incident solar radia-tion is focused from an array of heliostats onto a tower-mounted secondary mirror which redirects the focused solar radiation down through a window onto the surface of a vertically-moving bed of coal, or a fluidized bed of coal, contained within a gasification reactor.  The reactor is designed to minimize con-tact between the window and solids in the reactor.  Steam in-troduced into the gasification reactor reacts with the heated coal to produce gas consisting mainly of carbon monoxide and hydrogen, commonly called "synthesis gas", which can be con-verted to methane, methanol, gasoline, and other useful pro-ducts.  One of the novel features of the invention is the gen-eration of process steam at the rear surface of the secondary mirror.
