Patent EP-0203335-B1 (EP)
IPC: G01F11/24
Filed: 1986-04-12
Granted: 1990-03-21
Abstract: The apparatus for the dosed delivery of a granular solid material to a reaction container possessing a delivery inlet possesses a dosing device comprising a piston-cylinder unit which opens or discharges into the base or floor of a transfer chamber. The solid material which exits or leaves the dosing device is conveyed in the transfer chamber by means of a rotating conveyor component to a funnel whose inlet opening is located in the base or floor of the transfer chamber. The conveyor elements or cavities of the conveyor component extend over the entire cross section of the inner volume of the transfer chamber such that the solid material is transferred without loss from the dosing device to the funnel which discharges into the delivery inlet of the reaction container and the conveyor component seals the gas volume above the funnel.

Abstract: A bolt is prevented from rotating, whilst the nut is being screwed into place, by a small projection (3) in the corner between the undersurface of the bolt head (1) and the bolt shank (2). The projection has a sharp edge (103) which is inclined at an angle (a) to the bolt axis. At its junction with the undersurface of the head the projection extends radially for a distance (b). The latter is greater than the difference between the dia. (D) of the hole for the bolt and the dia. (d) of the bolt shank.

Abstract: A remote control commander for an apparatus, such as VTR deck, includes a rotary dial assembly (200) rotatably mounted on a housing for manual operation by a user. The commander includes a position detector (21, 22, 213) for monitoring angular position of a rotary dial disc (210) of the assembly (200). The angular position and/or angular displacement of the rotary dial disc (210) represents which of a plurality of functions of the apparatus (10) is to be controlled. An encoder (24) produces an encoded signal which varies in dependence upon the angular position and/or angular displacement of the rotary dial disc (210). The encoded signal is transmitted through a transmitter (27) to a receiver (16) provided in the apparatus to be controlled. The received signal is decoded in the apparatus to trigger the function represented by the received signal.

Abstract: In a broadband ISDN with separate switching facilities for narrowband and for broadband services, connection test signals are inserted into narrow-band signal gaps in the broadband signal in each access circuit involved in a broadband connection; these signals in each case contain the address of the relevant access circuit and the address of the distant access circuit which may be contained in corresponding connection test signals received from the distant end. The connection test signals are checked by one of the two access circuits for the occurrence of the addresses of both access circuits and a test result service signal is transmitted to the associated switching processor, possibly only with a change in the connection test signal or when it deviates from a nominal signal. <IMAGE>

Granted: 1993-01-13
Abstract: A defrothing apparatus whose inlet opening of the foamed liquid contained in a foam duct of a primary flotation apparatus is provided in the bottom of the foam duct. Starting from the lower area of the defrothing apparatus, a rotary flow (potential vortex) is generated in the apparatus by a recirculated lqiuid quantity from a secondary flotation apparatus. In the core of the rotary flow the gas quantity (air) is collected and removed through a removal pipe. Consequently, the foamed liquid from the foam duct of the primary flotation stage which is pumped to the secondary flotation stage contains small shares of gas relative to the total quantity of liquid, thereby allowing the pump to be optimally sized of efficiency and better control of the system.

Abstract: A system for printing and dispensing chemical reagents in precisely controlled volumes onto a medium at a precisely controlled location. A jetting tube (432), comprising an orifice (433) at one end and a fluid receiving aperture (431) at the other end, is concentrically mounted within a cylindrical piezo-electric transducer (434). The fluid receiving aperture (431) is connected to a reservoir (200) containing a selected reagent by means of a filter (300). The reservoir is pressurized by a regulated air supply. An electrical signal of short duration is applied to the transducer. The pulse causes the transducer (434) and the volume defined by the jetting tube (432) to expand, thereby drawing in a small quantity of reagent fluid. The cessation of the pulse causes the transducer (434) and the volume of the jetting tube (432) to de-expand, thereby causing at least a substantially uniformly sized droplet of reagent fluid to be propelled through the orifice (433). The droplet may be directed to impact a printing medium or collected in a dispensing recepticle.

Abstract: A helical compression spring (3), particularly for a wheel suspension, is presented and specified, with a spring strut  having a shock absorber and the helical compression spring (3) and connected on one side to the body and on the other to the wheel, and with a transverse control arm. 
<??>When the helical compression spring (3) according to the invention is used on a wheel suspension, the transverse forces occurring on the piston rod of the shock absorber are reduced in that the helical compression spring (3) has a curved spring centre line (7) in the unloaded state. Owing to the fact that the spring centre line (7) is curved, transverse forces (FX, FY) and moments (MO, MU) are initiated as a result of which the line of application (9) of the spring force does not coincide with the spring centre line (7).

Title: Device for stacking sheet-like articles such as letters
IPC: B65H29/46
Filed: 1988-11-17
Granted: 1992-09-16
Abstract: The invention relates to a device for stacking flat articles, such as postal items. First guide means (9), which form part of a stacker head (7) and which bound a stack of articles (2) already stacked in a stacker bed (1) in a plane of stacking (D), carry out an imposed to-and-fro pulse movement between a rest position (A) and an outermost position (C) transversely to a supply line (3) and in line and level with the stack to make stack space for a short time for an article 2.2 to be stacked, which article is entering at that moment via the supply line (3). The pulse movement can be realized by hanging the first guide means (9) on the one hand by means of a first set of parallel leaf springs (17, 18) to a frame part (19, 20, 31, 32) in such a way that they can swing, and on the other hand by coupling them to the driving end (28) of drive means (25, 26) carried on bearings in the frame part. In the rest position (A) the stack pressure exerted in the plane of stacking (D) on the first guide means (9) of the stacker head (7) will (practically) completely be exerted as a sideways pushing force on the frame part. This fact can be utilized with advantage for a very accurate stack-force measurement. For that purpose the frame part is connected, on the one hand, via a second set of parallel leaf springs (33, 34) to the fixed world (35, 36, 4) and, on the other hand, via a coupling bar (37) to a force transducer (38, 39). A very small sideways displacement of the frame part under the sideways pushing force caused by the stack pressure is registered by the force transducer (39) and converted into a signal which can be used for a change of position, if any, of a stack support (8) for regulating the stack pressure.
