Title: Gas injection valve for liquid e.g. PVC suspensions - having a perforated truck piston with a head sealing against the wall of the suspension container
Inventor: HAGER CLAUS ING GRAD
IPC: B01J4/00
Filed: 1979-08-10
Abstract: A container for a liquid suspension, eg. a PVC suspension, is provided with a gas injection valve having a gas injection tube (3) extending through the wall (6) of the container and terminating flush with the inner surface (9) of the wall. A piston rod (5) is reciprocable within he tube and has a trunk piston (2) secured to one end, the tracking end of the piston carrying a soft ring (4) which seals with the gas tube. The rear end wall and side wall of the trunk piston contain apertures (15,14) and the leading end of the piston comprises a solid disc (1) having a rearwardly extending bezel (16) which in the valve closed position sealingly engages the end surface (17) of the gas tube. If desired a resilient ring, adapted to absorb 50%-80% of the closing force, is located under the disc adjacent the bezel. The valve is of use in introducing a gas eg. water vapour into a PVC suspension to degas it. With the valve even only slightly open the degassing gas flows through the piston and out of the small gap between it and the tube at high velocity to prevent ingress of particles into the piston.

Title: Variable angle jet for flight control - has air, for automatic control of jet angle, admitted through positioning sleeve for control at all angles
Inventor: KRANZ WALTER
IPC: F02K9/80
Filed: 1979-09-19
Abstract: A nozzle (4) is mounted on a fixed casing so as to be able to pivot about an axis (A) perpendicular to its centreline. A skirt (20) prolongs the nozzle in the direction of discharge. The nozzle has two openings (22a,22B) diametrically opposite each other on its downstream side. Control air is admitted to these through a recess (28) in a sleeve (26) round the nozzle. Displacement of the nozzle from the set position alters the distribution of flow through these openings to produce forces which return the nozzle to the set position. Movement of the sleeve by a positioner (30) alters the equilibrium and thus the set position.

Title: Tree trunk cutting process - using second computer to control conveyor speed for faster cutting
Inventor: HEINONEN ISMO
IPC: B27B1/00
Filed: 1980-03-13
Abstract: The tree trunk to be cut is measured, the results are fed into a computer, and the tree is axially moved by a conveyor into a cutting appliance, when it is retained for the period of time necessary for cutting. A second computer is programmed on the base of the data coming from the first computer, to select an acceleration/deceleration suitable for the drive unit (11) of the conveyor (5-7). The conveyor speed is accelerated during a first period of time (to-tl) and deceerated during a second period (t3-t6) until the conveyor is stopped. The cutting process is initiated before the conveyor is stopped and the acceleration phase of the conveyor is begun before the cutter (2) returns to the at-rest position.
Patent DE-3012364-A1 (DE)
Inventor: HAFENSCHER FRANZ
IPC: H02H7/08
Filed: 1980-03-29
Abstract: In the case of the method for controlling an electric motor (10) which is thermally loaded differently, said electric motor (10) is provided with a temperature sensor (5). The physical state change of the temperature sensor (5) is evaluated by an electronic circuit (7, 8). The electronic circuit (7, 8) acts on a motor drive unit (9) as a function of this evaluation in such a manner that the cooling-down time of the electric motor (10) between the periods during which current flows in it is influenced. This method allows an electric motor which is designed for a mean operating case to be operated in its optimum power range and to be protected reliably against overloading. <IMAGE>

Title: Device for pressing the circulating grinding belt of a belt-grinding machine onto the workpiece to be machined
Inventor: ZELLWEGER JUERG
IPC: B24B21/00
Filed: 1981-02-17
Abstract: The grinding belt (1) for grinding a workpiece (4) moves over an abrasive pad (9) which, together with the abrasive pad carrier (10) and a guide piece (15) located therebetween, is designed as a hollow body. Air is pressed into the abrasive pad carrier (10) by a blower (11), said air flowing, via outlets (14) and through through-passages, into individual chambers (21a-n) of the abrasive pad (9). The air escapes therefrom via appertaining openings (20a-n) in order to form an air cushion which presses the grinding belt (1) against the workpiece (4). In order that said air cushion, despite the individual chambers, is continuous, the intermediate walls (22) between said chambers are not guided right up to to the upper edge (23) of the abrasive pad. The abrasive pad carrier (10) can be vertically adjusted by means of devices (32) in order to be able to adapt the abrasive pad (9) to different conditions. By means of the air cushion, the circulating grinding belt (1) is lifted from the stationary abrasive pad (9) and pressed, virtually with uniform pressure, onto the workpiece (4). Owing to the lack of friction between abrasive pad (9) and grinding belt (1), uniform grinding is achieved. <IMAGE>

Title: Water-channelling interlocking and overlapping structure for heat-insulating panels
IPC: E04B1/70
Filed: 1981-02-27
Abstract: In the case of a heat-insulating element with a side interlocking part running in an inclined manner with respect to the laying plane, the ridge side of the side interlocking part is provided with a web which runs over the width of the side interlocking groove and of the side interlocking rib and engages into a corresponding cutout on the associated side interlocking part of a neighbouring heat-insulating panel. Correspondingly, on the eaves side, the other side interlocking part of the heat-insulating panel is provided with a web which extends over the width of the top interlocking groove and top interlocking rib. By means of a transverse channel which runs from the side interlocking part to the centre of the heat-insulating panel and is located on the ridge side of the horizontal overlapping, the water collecting in the side interlocking part is channelled away to the water-channelling ducts provided in the heat-insulating panel.
