Abstract: An attempt is made to base the differentiation on two charge packets transported in two adjacently situated CTD devices. For this purpose, use is made of a floating gate which is common to the two CTD devices and which undergoes a first potential change during the removal of the first charge packet and a second potential change, opposite to the first, during the presentation of the second charge packet and which is connected to the circuit output. An advantage is the easy integrability of the circuit which is a common component in the CTDs. The field of application comprises devices for analog signal processing. (Figure 1) <IMAGE>

Abstract: A remotely controlled automotive transmission shifting mechanism for effecting engagement of the respective gears with a force that varies in accordance with the gear selected. Pneumatic pressure from a compressed air storage tank is connected via a choke to a pneumatic actuating cylinder that effects gear engagement. A signal corresponding to the instantaneous pressure effective at the actuating cylinder is compared in an evaluating circuit with a reference value assigned to the gear selected. When the compared signals match, a solenoid valve is actuated to cut off further pressurization of the actuating cylinder and thereby modulate the gear actuating force in accordance with the gear selected. Following gear engagement, the gear actuating pressure is released.

Abstract: The method uses digital data processing means and stored representations of a table of textual block identifiers for locating in a stored textual data base those textual blocks having the best match with a query. Textual block identifiers each provide an indication of a textual block in a stored data base which contains the corresponding word. The method comprises the following steps: A query word is received having representations of a plurality of words to be located in textual blocks in the stored data base. For each of a plurality of the query words, determine a corresponding set of equivalent words which are contained in the stored data base. Each set of equivalent words is equivalent to the corresponding query word. Each equivalent word has a corresponding group of textual block identifiers represented in the stored table. Process the representations of the textual block identifiers in those groups which correspond to the determined equivalent words to thereby form a score for at least one textual block. The score provides an indication of the total number of the sets which have at least one equivalent word in the at least one textual block. The score is utilized to provide output data pertaining to selected textual blocks in the stored textual data base.

Abstract: An ion-processing method and apparatus utilizing a slender tubular member (1) having an open end and an inlet conduit. The tubular member is positioned to bring the open end in spaced juxtaposition with a workpiece (2) across a small gap of a size of 10 and 1000µm in an evacuated atmosphere. Ionizable gas is supplied into the slender tubular member through the inlet conduit for feeding it into the small gap through the open end. A power supply (6) is provided to energize the supplied gas to form ions thereof and to apply an accelerating potential to the formed ions to cause them to propel in a beam across the small gap and to impinge onto a limited area of the surface of the workpiece juxtaposed with the open end of the slender tubular member. The pressure within the small gap, ranging between 10 -4  and 10 -1  Torr (13.3x10 -3  and 13.3 Pa), is maintained in excess of the pressure of the atmosphere surrounding the gap, ranging between 10- 6  and 10- 4  Torr (13.3 x 10 -5  and 13.3 x 10 -3  Pa).

Abstract: A billet heating furnace of the enclosed skid type comprises a feed mechanism (47) for regularly adding to and pushing a row of billets along a skid (31) extending through a furnace chamber (22) which is formed by a lower section (1) and an upper section (2) hinged to the lower section so that the chamber can be opened and closed. The furnace is heated by at least one high velocity premix gas burner (28) mounted in the upper section of the furnace chamber and controlled so as to raise and maintain an operating temperature in the chamber which is higher than the melting temperature of the billets and which is effective to raise the temperature of the billets passing through the furnace chamber to a suitable stamping temperature. At the outlet end of the furnace chamber the heated billets move onto a delivery path (55, 56, 57) for passage to a press. Along this path there is a billet detector (58 to 63) which responds to any interruption of the regular passage of billets to shut down the burners. The furnace chamber (22) is lined with ceramic fibre material (21) having a low thermal mass such that, if the burners (28) are shut down and there are billets stationary in the furnace chamber, the temperature in the chamber will fall  I  to below the melting temperature of the billets before the temperature of the billets can rise to the melting tempera- , ture. At the same time as the burners are shut down, a slide (64) in the delivery path (65) is opened so that any billets subsequently leaving the furnace chamber will be directed down a reject chute (66) until the furnace operator decides that the feed to the press is ready to be recommenced.
