Title: Stencils, for applying characters using spraying apparatuses
Inventor: WEISS ERICH
IPC: B05D1/32
Filed: 1981-05-20
Abstract: Individual letter stencils are punched out of thin (approximately 2 mm) layers of plastic. Then they are pressed onto the object to which the writing is to be applied, by means of a holding frame which can be adjusted for every size. The frame is previously fastened with suckers or clamps. To ensure that the letter stencils are completely flat, holes are bored at short intervals (approx. 5 mm) in the horizontal part of the holding frame, into which holes specially bent steel wires can be inserted. After a short rotation, the clamps press the stencils in an optimum manner at points at which the stencil was previously slightly raised. Spraying can then begin.

Patent DE-3132250-A1 (DE)
Title: Loudspeaker enclosure
Inventor: DEUTSCH HANS
IPC: H04R5/02
Filed: 1981-08-14
Abstract: Loudspeaker enclosures of a stereo pair are described in which the low-frequency system in the loudspeaker enclosure is mounted radiating at an angle to the side of the side wall of the reproduction room so that the predominant proportion of the sound radiated by the low-frequency system, especially above 200 Hz, of both enclosures is reflected by the respective side wall and the two reflected beams meet at the optimum listener position. Due to this alignment also of the lower-frequency sound sources which contain valuable components for locating the relevant single sound sources, especially above 200 Hz, it is avoided that an extended sound source is heard at too great a distance (which is due to the angle between listener and the two enclosures and is sensed as such for psycho-acoustical reasons) or with too narrow a base width compared with the original - that is to say also distorted, and the optimum representation of a three-dimensional sound image is achieved undistorted in its true magnitude.

Title: Method for adjusting the ratio of the replacement air flow to the discharge air flow in an air heating system
Inventor: KARI MARKKU
IPC: F24F12/00
Filed: 1981-11-07
Abstract: A method for adjusting the ratio of the replacement air flow to the discharge air flow in an air heating system is described. In air heating systems, a state is sought, in which, even instantaneously, as much replacement air flows into the building as discharge air flows out of the building. This aim is achieved by means of the invention which is based on the idea that if the temperature change of both air flows after flowing through the heat recovery arrangement is the same, the air flows themselves are also the same size. Consequently, by measuring the relevant temperature differences and by mutual comparison of the same, a very reliable picture of the ratio of the air flows is received.

Title: Heated roller fixing device for electrophotographic copying devices
Inventor: LUECK GERD DIPL ING
IPC: G03G15/20
Filed: 1982-10-13
Abstract: In a heated roller fixing device for electrophotographic copying devices with, arranged inside the heated roller (2), a thermostatically regulated heating element (5), the surface temperature of the heated roller (2) is measured contactlessly by means of a thermochain (16) consisting of thermoelements and the measuring result is entered into the temperature regulating circuit of the heated roller. The use of a thermochain (16) allows a relatively large distance from the heated roller surface to be maintained, as a result of which the measuring element is protected against dirtying and, as a result of its relative insensitivity to changes of distance, can be replaced easily. The response time of the thermochain, which is short in relation to other measuring arrangements, increases the regulating accuracy which can be achieved. <IMAGE>
