Patent DE-3140126-A1 (DE)
Title: Enlarging (enlarger) lens
Inventor: BAAB ALBERT
IPC: G03B27/32
Filed: 1981-10-09
Abstract: Enlarging lens having a linear f-stop (f-number) scale, in which the stop setting ring engages for half and full stop values. Both the viewing window and the setting markings are illuminated. The enlarging lens has a preset diaphragm by means of which focusing can be carried out with full aperture (stop opening). The desired working aperture is set as usual by turning the stop setting ring. By actuating a control ring by means of a handle, the diaphragm is completely opened without the preset working aperture being changed in the process. After focusing is completed, or after recorrection, the diaphragm is brought into the working aperture position again by actuating the control ring in the opposite direction. Disconnecting the diaphragm engagement is likewise performed with the aid of the control ring.

Title: Method and control circuit to supply power to model vehicles fed via a common supply line
IPC: A63H19/24
Filed: 1981-10-30
Abstract: A method and control circuit are indicated to supply power to a plurality of model vehicles, such as model railway vehicles, fed via a common supply line in order to be able to eliminate the voltage changes which occur on the common supply line due to the simultaneous operation of the plurality of model vehicles. For this purpose, the supply voltage available in each case on the common supply line (1) is evaluated with the aid of a measurement transformer (2) which acts on at least one second control element (3) by means of its output signal. This second control element (3) is coupled to one or more first control elements (4) with which the control commands to be sent in each case to the individual model vehicles can be manually set. The control commands are transmitted by a signal generator (5) via an unstabilised power component (6) to the common supply line (1). If a plurality of model vehicles are supplied via the common supply line with control commands in such a way that they all simultaneously extract a relatively high current in order to power their drive motors, the supply voltage available on the supply line can fall, whereby in turn the model vehicles do not reach their speeds predefined by the control commands. Due to the effect of the second control element(s) (3) determined by a supply voltage drop of this type, the control commands transmitted by the signal generator are modified in such a way that the model vehicles reach their required speeds despite the lower supply voltage. The inverse conditions occur, however, when a rise in the supply voltage takes place due to a reduction in the current drain occasioned by a plurality of simultaneously operated model vehicles, whereby the speed of the model vehicles still being operated would in turn rise above the speed predefined by the control commands. <IMAGE>
Patent DE-3147460-A1 (DE)
Title: Process and device for separating liquid mixtures by vaporisation and condensation
Inventor: WINTER KARL DIPL PHYS
IPC: B01D3/00
Filed: 1981-12-01
Abstract: In vacuum distillation, a certain lowering of the distillation temperature as compared with the boiling point at atmospheric pressure is achieved. Instead of this lowering of the total pressure in the distillation device, the present invention proposes the use of a carrier gas which is circulated and heated and cooled by an external heat transfer medium circulation. This likewise results in a lowering of the vaporisation temperature and can, furthermore, also provide sterile and highly pure products by the application of gas filters.

The endless flat belt (47) belonging to the flat-belt drive is in contact with rotatable elements (64 to 67) which are connected to the tensioner shafts (15 to 18). The flat belt (47) is pressed against the rotatable elements (64 to 67) by loaded pressure rollers (68). The invention is intended to afford the preconditions for ensuring that all yarns drawn off from a bobbin creel arrive in a simple way at a winding machine with, as far as possible, the same yarn tension.   <IMAGE>

Title: Pneumatic feed for circular saws, routers, planing machines or the like
Inventor: BECKER ERWIN
IPC: B27C1/12
Filed: 1982-07-02
Abstract: The invention relates to a partly pneumatic feed for circular saws, routers, planing machines or the like. In circular saws, routers and planing machines, the workpieces are usually placed manually against the machine tools. In the process, due to reaching around in order to pull the workpieces out of the machine, a brief interruption in the pushing action results, which produces burns and increased tool wear. Furthermore, the proximity of the hand to the tool constitutes an increased accident hazard. According to the invention, an air cylinder is fitted into the machine stop or into the machine table, which air cylinder is provided with a transport claw. The transport claw (5) is pressed by workpiece contact against a light spring into a groove (11), springs out again after the workpiece passes over and in the process controls the working stroke of the cylinder via the valves (8 and 9). <IMAGE>

Title: Hole punch
Inventor: MORI CHUZO
IPC: B26F1/36
Filed: 1982-07-09
Abstract: A hole punch, in particular a large-sized hole punch for simultaneously perforating a thick pile of paper sheets has a gear mechanism which is functionally assigned to a handle in order to move vertically a pair of paper-holding plates, the holding plates cooperating with a pair of cylindrical punching elements provided on a base. In the hole punch, the force required to move the handle for the perforating operation is considerably reduced. A baseplate having a pair of openings for defining a passage for in each case one punching element is mounted rotatably and vertically on the base and is normally upwardly prestressed in order to facilitate removal of the punching element from a thick pile of paper sheets after performing a perforating operation. The punching elements and paper-holding plates are removably fixed to the base and the gear mechanism, so that they can be easily exchanged for new ones.

Title: Arrangement for controlling the fibre concentration in a fibre suspension
Inventor: ANDERSSON NILS ERIC DIPL ING
IPC: D21F1/08
Filed: 1982-11-27
Abstract: In an arrangement for controlling the fibre concentration of a fibre suspension in an installation, dilution water is fed to the concentrated suspension via a line (17) from a tank (1) via an adjustable valve (11, 12) which is controlled by a concentration controller (15) which is fed, in addition to the set value, with the actual value of the concentration, measured by the instrument (13, 14) downstream of the point where the dilution water is introduced into the line (17). According to the invention, measuring elements (26 or 28, 29) are provided which emit a measured signal (27 or 30) for the concentration in a suspension tank (1) or at the outlet thereof. This measured signal is fed forward to the concentration controller (15) via the signal line (31) in such a way that, when the measured signal (27, 30) changes, the valve (11, 12) for the dilution water is adjusted in the direction opposite to that of the measured concentration change, even before a change in the concentration is detected by the measuring element (13, 14) of the concentration controller. A corresponding feeding-forward of the measured concentration value obtained at the tank (1) can also be fed forward to the controller (10) for a flow control, which may be present, for rough dilution of the suspension. The response sensitivity and stability of the control arrangement are substantially increased by the invention. <IMAGE>
