Abstract: The scanning system uses an objective lens (601) for focussing the scanning beam to a light spot on the surface of the recording disc, with an electromagnetic drive for continuous correction of the objective lens position to maintain the beam in alignment with the recording track. The electromagnetic drive acts on a lens holder (603) lying coaxial to the optical axis of the objective lens (601) and comprising a ring with magnetic poles at its ends. The ring has 2 axially offset permanent magnetic elements, the cooperating magnetic coil system comprising at least 3 segmental coil sets (613, 615, 619), each comprising 2 segment coils arranged at equal spacings around the periphery of the lens holder (603).

Abstract: A group elevator control wherein the calls entered by means of call registering devices at a main floor for desired destination floors are assigned to the next arriving or already present car, and indicated so that no doubts can arise for passengers, whose calls had been acknowledged, in the choice of the correct car. A locking circuit responds to the presence of several cars at the main floor by only opening the doors of one elevator and assigning the entered calls to this elevator. The call registering devices are blocked at a time dependent on the start of the door closure or after the entering of a certain number of calls, by means of an inhibiting circuit and released again at the departure of the respective car. During the retention cycle, an indicator element, arranged in an indicator panel of the call registering devices, signals the blocking.

Abstract: The bale handling machine comprises a transversely extending main frame (10) mounted on which are a number of independent bale pickup grabs (4).  Each grab has movable tines (19) which, in an operative position, engage a bale (21) and, in an inoperative position, are retracted clear of the bale.  An actuator (4) associated with each grab is operable to move the respective tines to and from the operative position. The actuators of the grabs are connectable in parallel to common drive and releasable locks are associated with the tines of each grab for locking them in the operative position. Only the tines which are unlocked against movement to the operative position and have not already achieved the latter position, will be moved to the operative position when the drive is operated to energise the actuator for moving the tines to the operative position.

Abstract: A method and apparatus for conversion of a plurality of information signals from parallel to serial representation and vice versa. According to the invention the time delay introduced by the use of ordinary shift registers is obviated by shortly transferring of energy to or from specified locations of an energy propagation path. When using e.g. microwave energy, serial information signals may be transmitted by transferring electrical charges to specified locations of a microstrip path at predetermined points of time and the parallel information may be retrieved from said serial information signals by sensing specified locations of the microstrip path at corresponding points of time.

Abstract: For making the locking means 1 for the opening of a self-service device, in particular an automatic teller machine, water-repellent, a locking flap 7 is provided, the outside of which is indented 16. Locking flap 7, pivotable about axis 9, is positioned in the upper region behind a projecting wall panel 3 and in the lower region in front of a recessed wall panel 4. As gap 18 is opened, its width increases, so that any ice formed may be broken up or jammed objects are released automatically. The self-locking latch and actuator means 31, favourably designed according to the invention, uses an actuating lever 38 which is pivotable about axis 9. The actuating lever comprises a particularly shaped guide slot 37 which is engaged by the actuator means (32, 34, 35). In the first part 39 of the guide slot 37, no displacement work is performed by the actuator means, whereas in the second part 40, which is positioned at an angle to the first part 39, displacement work is performed in favourable directional association.

Abstract: In this process for managing passenger traffic at the main stop (HAUPTHALT) of a lift group with n lift cages, sensors (SENSOR. A; SENSOR. B ... SENSOR. N) monitor entering passenger traffic and sensors (SENSOR. 1; SENSOR. 2 ... SENSOR. N) monitor exiting, building-filling passenger traffic. The higher-order algorithm (REGLER) implemented in the processor (RECHNER) determines the traffic volume and the actual departure load of the lift group from the sensor data. Depending on the traffic volume, the actual departure load and constants imported from the input/output unit (TERMINAL), the higher- order algorithm calculates the carrying capacity of the lift group according to a control algorithm. The carrying capacity of the lift group is assigned to the lower-order algorithms (REGLER. 1; REGLER. 2 ... REGLER. n) according to the number of lift cages and the nominal load of the relevant lift cage. The lower-order algorithm of the relevant lift cage calculates the optimum departure load on the basis of the assigned carrying capacity and the circulation time of the relevant lift cage. Depending on the optimum departure load and the actual departure load of the relevant lift cage, the lower-order algorithm determines, according to a control algorithm, the adjusted departure load which is to be imposed on the relevant lift cage.

Reaction is carried out by the one-stage or  pre-polymer process with an NCO no. of 70-125. The novel features are that water is added in an amt. of min. 10 mole-% w.r.t. the NCO content of (I); and the reaction mixt. is cast in an open mould, so that its vol. is at least 95% filled, then the mould is closed tightly so that the CO2 formed by the reaction of water and (I) can cause practically no expansion. Before filling, the mould is heated to a temp. higher than that of the reaction mixt. Shrinkage during cure is compensated by continuously reducing the mould cavity, so that the reaction pressure in the mould is maintained until the moulding is released.

Abstract: The synchronisation arrangement includes a waveform and synchronisation information generator to supply synchronisation information for transmission with a data stream over digital switching networks. The synchronisation information includes two different patterns, phased displaced with respect to each other. Interfaces connect peripheral devices to the networks and are adapted to detect and validate the synchronisation information. The checks made are in respect of detecting both patterns, the amount of phase displacement, and the correct sequence. If the synchronisation information is invalid, the detecting interface selects a data stream from another network exclusively for use by the corresponding peripheral device.

Abstract: This invention is directed to conducting chemical reactions in reverse micelle or microemulsion systems comprising a substantially discontinuous phase including a polar fluid, typically an aqueous fluid, and a microemulsion promoter, typically a surfactant, for facilitating the formation of reverse micelles in the system. The system further includes a substantially continuous phase including a non-polar or low-polarity fluid material which is a gas under standard temperature and pressure and has a critical density, and which is generally a water-insoluble fluid in a near critical or supercritical state. Thus, the microemulsion system is maintained at a pressure and temperature such that the density of the non-polar or low-polarity fluid exceeds the critical density thereof. The method of carrying out chemical reactions generally comprises forming a first reverse micelle system including an aqueous fluid including reverse micelles in a water-insoluble fluid in the supercritical state. Then, a first reactant is introduced into the first reverse micelle system, and a chemical reaction is carried out with the first reactant to form a reaction product. In general, the first reactant can be incorporated into, and the product formed in, the reverse micelles. A second reactant can also be incorporated in the first reverse micelle system which is capable of reacting with the first reactant to form a product.

Abstract: In a configuration, a received radiation is converted into a storable secondary energy by a transducer. From the stored secondary energy, a nonlinear element of the configuration generates a radio-frequency signal. A coding element impresses an information item on the radio-frequency signal to generate a response signal. The impressed information can be information on the value of an environmental parameter detected by the coding element, which, in turn, can be a physical quantity or type and/or concentration of a substance.
