Abstract: There is described a novel process for preparing 1-(aminomethyl)cyclohexaneacetic acid, a drug used as anticonvulsive. 
<??>To this end, a dialkyl (1-cyanocyclohexyl)malonate is decarbalkoxylated to give the corresponding alkyl (1-cyanocyclohexyl)acetate, then transesterified with a benzyl alcohol and finally hydrogenated to give the end product. 
<??>Benzyl (1-cyanocyclohexyl)acetates can also be obtained by reacting (1-cyanocyclohexyl)acetonitrile with a benzyl alcohol in the presence of a mineral acid, followed by hydrolysis with water. 
<??>Alkyl (1-cyanocyclohexyl)acetates can also be obtained by reacting (1-cyanocyclohexyl)acetonitrile with a lower aliphatic alcohol in the presence of a mineral acid, followed by hydrolysis with water.

Abstract: The invention relates to a process and a device for positioning and controlling a high-power energy source, in particular a laser, relative to a workpiece. In this case, the laser beam is positioned by means of an optical system and the surround field of the impingement site of the laser beam on the workpiece is observed during laser operation, whereupon the laser beam is controlled in accordance with the result of the observation. In order simply and exactly to configure the positioning and control of the laser beam, the direction of observation is selected according to the invention to be different to the direction of the laser beam, and in addition the impingement site of the laser beam on the workpiece itself is observed during laser operation. No additional illumination is required apart from the working laser. By optical filtering, there is generated in the observing plane an image of the impingement site relative to its surround field, from the contrast of which the information on positioning and controlling the laser is determined. <IMAGE>

Abstract: The invention relates to a rotating winder for stranding products which has a rotor (1) connected to a drive motor and is borne on a machine frame and in which a winding drum (2) is rotatably fitted which is connected to a drive motor and the axis of rotation (3) of which runs transversely to the rotor axis (4), and which has a traversing fork (14) movable parallel to the winding drum axis (3) as a traversing device for the substances to be wound. The traversing fork (14) moving to and fro transversely to the rotor axis (4) generates changing imbalances which forbid a higher working speed. The provision of a counterweight (15; 19) to the traversing fork (14; 17) guided in the opposite direction to the traversing fork (14; 17) on the traversing device and connected to the traversing fork (14) via a transmission device preferably in the form of a puller (31) in the region of the rotor axis (4) makes for considerably improved balance so that greater efficiency can be achieved with a higher operating speed.

Abstract: A digital data communication system enables host computer to communicate with a great number of data terminals having specified functions. Communication from the host computer proceeds through a medium or long distance, high power transceiver and through a multiplex system to one of a number of portable communication devices. The communication devices preferably contain internal power supplies, such as rechargeable NiCad battery packs. The devices may be carried on a person's belt, or may be mounted within or on a service vehicle, for example, a forklift truck for use in warehouse operations or a merchandise delivery route vehicle. The communication devices are adapted to function as communication relay devices between the host computer and selected ones of the data terminals. Each communication device includes a first type, low power transceiver to communicate within a first channel and at a low power transmission level with a selected number of the data terminals which also feature such first type transceivers. Each communication device further includes a high power transceiver to communicate within a second channel with the transceiver of the host computer. A microprocessor operated address controller allows the communication device to control low power communication among the data terminals by receiving and re-transmitting locally directed communications. The controller and the controlling protocol further relays data messages between the low power communication level and host computer. In operation the device receives data messages on one of the transceivers and transmits them on the other. The communication device further may contain sufficient memory capacity to permit periodic batch type data transmission between the host computer and the communication device. The ability to switch from a high power, high precision and high cost transmission system to a low power, low precision and low cost transmission system at the level at which a great number of data terminal devices are used provides system flexibility at a reasonable cost.
