Title: Cylindrical rotor electric motor with axial shaft displacement - spring loaded immobiliser with electromagnet coil centering the rotor for motor start up
IPC: H02K7/12
Filed: 1990-04-24

Title: Dosing valve for regulating flows of gas - uses valve element inside flow chamber to change flow direction
Inventor: BERGER UDO
IPC: F16K3/32
Filed: 1990-11-26
Abstract: The dosing valve for laboratory instruments has a hollow cylindrical valve housing defined on one side by an adjustment mechanism for the valve element fitted in the valve seat, and on the other by the wall. The cylindrical valve element is mounted with its cylinder axis perpendicular to the inlet opening and along at least one part of the part of the cylindrical body of the valve element facing the outlet opening has a material recess which alters the direction of the media flow relative to the direction preset by the valve chamber whereby the material recess always releases the media flow in the direction of the outlet opening. The remaining part of the sleeve face of the cylindrical valve element along each radius line of the cylinder axis is substantially larger than the upper face of the inlet opening. The displacement path of the valve over the inlet opening has at least the length of the direction-changing recess along the cylinder axis of the valve element. ADVANTAGE - Since the valve element changing the flow volume also changes several factors at the same time a fine adjustment of the flow is now possible.

Patent DE-4103454-A1 (DE)
Inventor: COCHIUS RICHARD
IPC: F27B9/20
Filed: 1991-02-06
Abstract: The workpiece charges are transported stepwise through the throughflow furnace lying on movable floor elements (12), and at each step they are individually lifted from below, beginning at the outlet side end (9) of the throughflow furnace, and displaced by one step. In this manner, even extremely heavy workpiece charges, such as coils, can be heat-treated in a throughflow furnace. Transport is effected by a transfer machine (13) which can travel in the longitudinal direction of the furnace, beneath the furnace floor (14) in a space (15) under the furnace, and which can engage through the furnace floor (14) with a lifting device (18). For this purpose the furnace floor has two apertures (20,21) running in the longitudinal direction of the furnace. The movable floor elements (12) form a closed upper floor which covers the apertures (20,21) of the furnace floor. The space (15) under the furnace is thus thermally insulated. <IMAGE>

Title: Storing image data in video communication system - opening image data and control signal banks, and storing side data of image data
Inventor: ICHIKI TORU
IPC: H04N1/32
Filed: 1991-02-27
Abstract: For the image data storage, an image data bank and a control signal bank are formed.

Title: Tensioned bolt arrangement for securing vibratory sieve - has spring tension applied through intermediate sleeve with end collar limiting travel if bolt fails
Inventor: HAELG WERNER
IPC: B07B1/48
Filed: 1991-03-28
Abstract: The tensioned bolt arrangement secures a vibrating sieve (9) to frame (1). It consists of a tension bolt (5') having one end (5,5a) hooked over the edge (11) of the sieve, and the other end (5b) tensioned away from the sieve frame by a coil spring (10). One end (10a) of the spring abuts against the sieve frame and the other end (10b) against a nut (4) screwed onto an intermediate sleeve (2a) co-axially surrounding the tension bolt and passing through a hole (3') in the frame. On the inner end of the sleeve is a collar (2) limiting its axial movement. A nut (6) on the end of the tension bolt can be screwed up against the outer end (2c) of the sleeve to adjust the spring force . The intermediate sleeve has a length greater than that of the loaded spring but less than that of the unloaded spring. In the event of failure of the hooked end of the tension bolt, the spring is unloaded by a small distance (a), limiting the energy propelling the bolt. ADVANTAGE - Greater safety without increase in vibratory mass or overloading of adjacent bolts.

The wheel is lowered by a lowering device including a frame (16) controlled by a hydraulic cylinder (18). The cylinder (18) acts on the frame so that the cutting wheel moves vertically relative to it. USE - Esp. for laying cables on sea-bed.
Patent DE-4116454-A1 (DE)
Inventor: HEINDORF HELMUT DIPL ING
IPC: H01H71/52
Filed: 1991-05-18
Abstract: The mechanism has a hand-operating toggle (1) fitted inside a casing (2) and spring-loaded in the off direction on which is articulated a lever (3, 4). During switch-on, a contact lever (5) pivoting about a spindle (2d) against the force of a spring (7) is supported on the lever. The contact lever (5) acts on a fixed contact (6) and can be clamped in the made position against the force of the spring (7). It is the purpose of the invention to simplify the supporting link between the lever (3, 4) and the contact lever (5) in order to obtain uniform release forces with only slight spreads within a production run of switches. To this end, between the hand-operating toggle (1) and the contact lever (5) is fitted a toggle lever consisting of a tension lever (3) and a bracket (4) which, in its stable position, is virtually tensioned and in which the form of the tension lever (3) causes its two articulated arms to assume a precisely defined top dead centre position. Thus during switch-on and in the on position, the toggle lever (3, 4) acts as a rigid lever. Only a substantially perpendicular load on its joint (3b/4a) applied via a release lever (9) towards dead centre causes the toggle lever (3, 4) to assume an unstable position under the effect of the contact lever's (5) return through the force of the spring (7). This releases the rigid connection between the hand-operating toggle (1) and the contact lever (5) so that the lever arm (5c) on the contact side can pivot into its breaking position. The mechanism of the invention is particularly suitable for fault-current protective switches and automatic cut-outs.
