Abstract: Polyarylates are modified to achieve ductile failure during practical impact without adversely effecting the high peak force by mixing the polyarylate with a polyester derived from an aliphatic or cycloaliphatic diol and an aromatic dicarboxylic acid and an impact modifier comprising an EPDM elastomer. To reduce notch sensitivity of the above composition, inclusion of a second impact modifier comprising an acrylic multiphase interpolymer is required.

Abstract: To improve the quality, in particular the organoleptic properties, of roasted coffee, the acidity of the green (unroasted) coffee beans is increased. This is preferably carried out by impregnating the raw coffee beans with acid in aqueous solution. This impregnation results in a marked increase in the content of titratable acids in the roasted coffee and in an improved quality as regards flavour, taste and colour of the roasted coffee.

Abstract: An instrument-supporting, articulated device has a distal end capable of supporting an instrument in the region of a surgical operating site. The device has at least one joint (15) that supports a movable distal support element (10) relative to a proximal support, the being joint associated with a mode selector. The joint has structure capable, upon selection of a first mode of operation by the selector, of enabling relatively free motion of the joint for achieving a desired position of the instrument and the joint has structure capable, upon selection of a second mode of operation by the selector, to set the position of the instrument in space with lightly loaded restraint. The lightly loaded restraint is of a value that, while the second mode continues to be selected, the user may adjust the position of the instrument by application of a light force to the instrument and upon release of such light force by the user, the instrument will remain in the newly adjusted position.

Abstract: A parallel binary byte adder performs addition and subtraction on the individual bytes of an A-operand (10) and a B-operand (12) as well as on the entire A and B operand. An A-operand is input to a special adder circuit (20). A B-operand is modified in a set up logic circuit (14), in accordance with the specific operation to be performed, before being input to the special adder circuit (20). A set/mask logic (18) generates set, mask and carry signals which are further input to the special adder circuit (20). The special adder circuit (20) includes an auxiliary functions circuit (20a) and a pseudo carry circuit (20b) for generating a set of "variables" in response to the A-operand (10), the modified B-operand (16), and the output of the set/mask logic (18). The special adder circuit (20) further includes a sum circuit (20c) which is implemented from three separate Boolean equations, the equations being a function of the "variables". The first Boolean equation relates to bits 0-5 of a particular byte of the A-operand (10) and the modified B-operand (16) undergoing addition or subtraction. The second Boolean equation relates to bit 6 of the particular byte, and the third Boolean equation relates to bit 7 of the particular byte. The special adder (20) is responsive to the A-operand (10), the modified B-operand (16), an output of the set of logic (14), and an output of the Set/Mask logic (18) for performing an operation on bits 0-5 of a particular byte, associated with the A-operand (10) and the modified B-operand (16) undergoing addition or subtraction, performing an operation on bit 6 of the particular byte of the A-operand (10) and modified B-operand (16), performing an operation on bit 7 of the particular byte of the A-operand (10) and modified B-operand (16), and concatenating the results of the operations associated with bits 0-5, bit 6, and bit 7 of the particular byte of the A-operand (10) and the modified B-operand (16). The concatenated results represent the sum or difference of the particular byte associated with the A-operand (10) and the modified B-operand (16).

Abstract: An apparatus and method for making center-filled chewing gum, in which product having up to at least 35-40% by weight of center fill can be produced. The apparatus comprises an extruder barrel and nozzle arrangement (11) which extrudes a tubular rope of gum (G) through an annular orifice (30), and at the same time supplies a center-fill material (F) to the hollow interior (V) of the tubular rope through a central nozzle (20,21) concentric with the orifice. The center-fill material (F) is fed into the hollow interior (V) of the gum rope (G) at a rate sufficient to just fill the void produced in the gum rope (G) as it is extruded through the nozzle (20,21), and without exerting a compressive pressure thereon. With this apparatus and method, center-filled chewing gum can be produced with up to at least 35-40% by weight of center-fill material and at the same time uniform wall thickness and consistency for the center-filled product can be maintained.

Abstract: A method is described for transferring idempotent and non-­idempotent requests over a network between two or more computer systems 10,20. The method comprises sending a series of messages over a network to perform the request. The method defines five types of messages: a request message 110, a response message 113, a slow request message 112, an acknowledge message 114, and a state of health message. A slow request is handled by sending a slow request message 112 in response to a retransmitted request message 111. When the computer system which received the request message has completed the request, a response message 113 is sent to the requesting computer system. The requesting computer system then transmits an acknowledge message 114 to acknowledge receipt of the response.

Abstract: A bipolar-complementary metal oxide semiconductor (Bi-CMOS) inverter includes a CMOS inverter (T1, T2), an npn-type bipolar transistor (Q1), and an n-channel MOS transistor (T3). An emitter of an n-channel MOS transistor (T2) of the CMOS inverter is connected to an emitter of the bipolar transistor (Q1) and a drain of the MOS transistor (T3). A gate of the MOS transistor (T3) is connected to an input of the CMOS inverter. When an input voltage (Vin) applied to the CMOS inverter is switched to a high level, charges at an output of the CMOS inverter (T1, T2) and at the emitter of the bipolar transistor (Q1) are pulled out. During this time, the voltage at the output of the CMOS inverter (T1, T2) decreases so as to follow the decrease of the voltage at the emitter of the bipolar transistor (Q1).

Abstract: The device for preparing hot beverages, such as coffee, tea or the like has a housing for accommodating switch and control elements and a heating device. Furthermore, the device has a fresh water container which forms a communicating system to recognise its filling level by means of a tubular water level display having a scale. In order to dispense with float-type bodies to display the filling level of the fresh water container, the water level display is constructed as an optical lens. This takes place in such a way that the scale and its numbers, letters or the like are visible in enlarged form in the length of the water level display which is filled with water and, in contrast, in reduced form in the other length situated above it. In this case, the transition between the two lengths reflects the filling level of the fresh water container. <IMAGE>

Abstract: An apparatus and a method of stopping a spindle motor for rotating a composite disk in a disk player. The composite disk contains a first area having information recorded thereon at a first rotational frequency, and a second area having information recorded thereon at a second rotational frequency which is greater than the first rotational frequency. The spindle motor is stopped when a stop or eject command is instructed during or after information is read from the second area of the composite disk by moving a pickup for reproducing information recorded on the disk to the first area and supplying a counter torque brake signal to the spindle motor, thereby slowing the rotational frequency of the disk to a rotational frequency in which information can be read from the first area. A further counter torque brake signal is supplied to the spindle motor for a predetermined amount of time after the moved pickup begins to read information recorded on the first area to thereby stop the rotation of the composite disk.
