Abstract: Apparatus and method for generating a dispersed dot half tone picture from a continuous tone picture involves the making of a thresholding decision at each picture element to decide whether or not a dot is printed in the output picture and is characterised in that cumulative weighted sums of the errors between the original continuous tone picture and the output half tone picture at each picture element are held for each column of the picture matrix and from these column sums of errors a sector sum of errors is formed and used in the thresholding decision. The column and sector sums of errors are up-dated by simple recursive relationships. Edge enhancement is introduced in a simple manner obviating the need to calculate a local greyscale average. Distracting patterns of dots in the output picture are broken up by the use of carefully selected threshold values.

Abstract: An integrator with a sampling stage at the input side has a first capacitor with associated electronic switches and has one or more amplifier stages each having a feedback path containing a second capacitor which is connected to the output of the sampling stage. The integrator has a first polarity commutator interconnected between the output of the sampling stage and the input of the first amplifier stage and a second polarity commutator at the output of one of the amplifier stages, the second polarity commutator being operated synchronously with the first polarity commutator. By periodic actuation of the polarity commutators, the low frequency noise voltage components, having amplitudes which vary minimally within a polarity reversal period, cancel when the integration results of successive periods of opposite polarity are added and are thus substantially eliminated.

Abstract: Multilingual computer-specified control messages are communicated to an operator in an operator-selected language by the combination of a message writer and a language changer. The language changer contains a set of message storage tables, each containing a set of control messages written in a particular language, and a set of message address tables, each message address table referencing a computer-generated message code indicative of a specific condition to a respective one of the control messages in an associated message location table. In accordance with an operator command indicative of a desired control message language, the language changer supplies the message writer with the corresponding message storage table and message address table. When the message writer is supplied with a computer-generated message code, it employs the message address table to translate the message code into a control message address and then transmits the control message located in the corresponding message storage table at the address obtained from the message address table to a visual display or to a voice synthesizer for communication to the operator.

Abstract: An oblong, plate-shaped power supply piece (2) has a contact support (5) on its one side. An arc guide piece (6), of ferro-magnetic material,  is  connected  to  the  latter. The  one  limb  (6a)  of the L-shaped arc guide piece (6) abuts against the power supply piece (2) and is connected thereto by means of rivets (9). An intermediate layer (7) of an electrically insulating material, e.g. a small plate of mica, is arranged between this limb (6a) and the power supply piece (2). The limb (6a) embraces the contact support (5) on the side, by means of which, an arc which occurs when the contact is opened can be rapidly transferred from the contact support (5) onto the arc guide piece (6). Despite the compact construction and low installed height of the contact piece (1), a magnetic self-blasting effect is generated by means of which the arc is driven away over the arc guide piece (6) from the contact support (5). <IMAGE>

Abstract: A friction clutch driven plate incorporates a hub member 11 and a friction disc carrier 14 between which there is arranged a torsional vibration damper. The torsional vibration damper takes the form of springs 26 arranged in windows 23, 24 in the friction disc carrier and 25 in the hub member together with a friction washer 27. The friction washer results in continuous frictional resistance to relative movement between the hub member and friction disc carrier while the springs provide resilient resistance to such angular movement. The springs and windows are arranged to provide some lost motion during which the springs are ineffective and the friction device alone controls relative movement. This arrangement is particularly useful for damping out idler gear rattle in front wheel drive vehicles.

Abstract: A method of seismic prospecting is disclosed wherein the seismic source (14) is excited in such a manner as to maximize the use of the energy (24) generated thereby. In certain cases it may be desirable to convert the received seismic signals to their frequency domain counterparts before performing subsequent processing. Such conversion may be performed using the discrete Fourier transform with the result that transformed values are obtained only at certain discrete frequencies. It may further be desirable that processing be performed only at subsets of the total set of discrete frequencies with the values at the remaining frequencies being discarded. In the practice of the present invention, source energy is generated only at those discrete frequencies at wich subsequent processing is to be performed. As a result there is substantially no source energy in the transform values at the frequencies which are discarded.
