Abstract: Die Erfindung betrifft ein Verfahren zum gleichmäßigen Erwärmen länglicher Werkstücke, (A) die einen sich über den größten Teil ihrer Länge erstreckenden Längenabschnitt mtt gleichformigem Querschnitt (10) und mindestens einen Langenabschnitt mit demgegenüber größerem Qerschnitt (12,14) aufweisen. Die Erwärmung erfolgt mit Hilfe eines mehrwindigen Induktors (30), der an einem beweglichen Induktorträger (54) od.dgl. koaxial zu einer Arbeitsstrecke (W) angeordnet ist, auf der sich die zu erwärmenden Werkstücke (A) bewegen. Bei induktiver Kopplung des Induktors (30) mit dem dickeren Längenauschnitt (12,14) des Werkstucks wird der Induktor gleichsinnig zu dem Werkstuck (A) bewegt, so daß die effektive Erwärmungsdauer des dickeren Längenabschnttts (12,14) des Werkstücks (A) erhöht und damit dieser Längenabschnitt auf die gleiche Temperatur erwärmt wird wie der dünnere Längenabschnitt (10) des Werkstücks (A). Ferner betrifft die Erfindung eine Einrichtung zur Durchführung des Verfahrens, die einen order auch mehrere auf einem Induktorträger (54) angeordnete Induktoren (30) aufweist, die in Transportrichtung der Werkstücke (A) über eine Teilstrecke beweglich und anschließend in die Ausgangsposition zurückstellbar sind.

Abstract: A circuit arrangement for centrally-controlled telecommunication exchange systems, particularly for time-division multiplex telephone exchange systems, with information exchange between sub-central devices, is characterized by the provision of an input/output processor device, in addition to the central control unit, which comprises an input memory portion and an output memory portion. The input memory portion is divided into sub-memories which receive information intended for a line trunk group and to be processed by the central control unit, while the output memory portion is divided into sub-memories which are assigned to respective buffers for information transfer between the sub-central devices, by-passing the central control unit. For the purpose of information transmission from one line trunk group to another, an auxiliary criterion is added to the information to be transmitted in addition to the address of the destination line trunk group, the auxiliary criterion causing the input/output processor device to write the information directly into the output sub-memory of that sub-central device which serves the destination line trunk group.

Abstract: A method and apparatus for proving a demand for air conditioning or heating upon startup of an air conditioning unit before the unit is allowed to effect heat transfer. A separate thermal sensing unit is provided in the return air to prove a demand for cooling prior to the conventional thermostat of the unit being energized to operate the unit in the normal manner. This method and apparatus prevents energy waste and unnecessary cycling at startup and low load conditions.

Abstract: An automatic focus correction system for E-beam lithography uses optical light from a narrow angle light source ;(10) to illuminate a horizontal slit (12), the image of which is projected onto a target surface (15). Prior to and after reflection of the slit image from the target surface the light beam is projected parallel to the target surface to minimize vertical space requirements in the E-beam column. Variations in height, z-position, cause the slit image to move vertically and the focus of reflection to shift laterally and this image is redeflected in the horizontal plane by a prism to a linear diode array (28) used to produce a video-type output signal. Autofocus electronics are used to convert the video output signal into an analog correction signal to the E-beam fine focus coil. The video-type signal is also converted to a digital height value to be used for corrections in beam magnification and rotation.

Abstract: An electrostatographic developer composition comprises toner and carrier particles which are magnetically attracted to one another, for example by the application of a magnetic field. Substantially no triboelectric charge is generated between the toner and carrier particles, the carrier particles being electrically conductive. The toner particles acquire induced electrical charges (which may be of either polarity) in proximity to an electrically charged surface. In a method for developing electrostatic latent images, the developer composition is brought into close proximity with the electrical potential existing in the region of an electrostatic latent image whereby charge of a polarity opposite to that of the electrical potential is induced into the toner particles, causing the toner particles to develop the latent image.

Abstract: Thermoforming apparatus of the kind having a heating station (B) and a forming station (C) wherein at the heating station there are provided upper and lower heaters (10, 11) for softening the thermoplastics sheet material (4) one of which heaters is moveable between the heating (B) and forming (C) stations and is arranged to convey heated sheets from the heating station (B) to the forming station (C). The means for conveying the sheet (4) to be formed between the stations preferably comprises a guide track extending between the stations, a carriage (8) on the guide track, and sheet gripper means (15, 16, 26) on the carriage (8). Preferably the guide track is pivoted at one end for vertical movement to provide clearance to enable the sheet to be advanced between successive stations. 
     From another aspect there is a method of heating a thermoplastics material comprising applying heat at a given level to the material from a heat source (18) of low thermal inertia, e.g. infra-red quartz electric resistance heaters, and successively or continuously reducing the level of heat applied to the material as the temperature of the material rises. Preferably the method comprises initially applying maximum heat available to the material monitoring the temperature of the material, comparing the monitored temperature of the material with the temperature of a predetermined temperature response of the same material, and controlling the heat applied to the material in accordance with the predetermined temperature response and in accordance with the monitored temperature so that the thermoplastic material is brought into a suitable condition to be thermoformed.

Abstract: A novel latent heat accumulative material capable of accumulating heat in a temperature range best suited for the storage of solar energy was obtained by adding an organic compound or compounds such as urea [CO(NH 2 ) 2 ] to a system consisting of sodium acetate (CH 3 C0 2 Na) and water (H 2 0). Further addition of a crystal nucleus forming material or materials such as sodium pyrophosphate decahydrate (Na 4 P 2 O 7 .10H 2 O) to said composition could minimize supercooling and allowed a wider scope of application of the present heat accumulative material.
