IPC: G02B21/08
Filed: 1987-03-17
Abstract: In order to increase the light efficiency (yield) of the illuminating system while maintaining freedom from colour aberrations (chromatic defects, colour defects), and at the same time obviate the necessity for readjusting the system even if the lamp bulb is changed, a reflector (4) is provided which surrounds the light source (1) and which produces a preferably enlarged image of the light source in the focal plane of the collector (2), which plane is on the light-source side and in which a ground glass screen (5) or another light-blurring element, for example an optical fibre element, is arranged. If possible, the light-blurring element can also be arranged in or in the proximity of an intermediate image plane of the light source (1). A gas-discharge lamp or a low-voltage tungsten-halogen lamp can also serve as light source (1), the reflector (4) covering a range of at least 180@ of the angle of emission of the light source (1). Furthermore, for producing a telecentric illuminating beam path, the condenser (3) preferable projects the image of the light source (1) to infinity. <IMAGE>

Title: Method and devices for improved shunting for rail goods traffic
Inventor: BELL KARL WALTER
IPC: B61J1/10
Filed: 1987-08-28
Abstract: The invention relates to a shunting method for rail goods wagons with the associated devices, in which method setting of the points, gravity shunting or shunting locomotives are dispensed with and in which, above all, it is possible to relocate the transfer of the individual wagons from the incoming track in the direction of the target track into an enclosed space so that disadvantages of shunting in the open air are avoided. Furthermore, the track area required for shunting can be reduced to a minimum. The idea of the invention provides for the wagons which are to be moved to be pulled or pushed onto a transverse transfer device, to be transferred to the target track using said device and to be ejected there by a device in order to be coupled to the target train.
Patent DE-3730234-A1 (DE)
Title: Method for echo suppression
Inventor: TRICK ULRICH DIPL ING
IPC: H04B3/23
Filed: 1987-09-09
Abstract: A large number of instantaneous values are required in the case of known methods for echo suppression, which instantaneous values are contained in a memory and must be read out and processed at a multiple of the transmission speed. The invention reduces the memory cost and the processing speed. The pulse shape of the four-wire input signals is changed by a transmission pulse former in such a manner that the pulse response of the echo channel is shortened, the echo signal being used to adjust the transmission pulse former. As a result of the shorter echo signal, fewer instantaneous values are required, and the processing speed is thus also lower. The method for echo suppression can be used in the case of four-wire/two-wire hybrid circuits, to be precise both in the case of analog hybrids and digital hybrids.

Title: Distributor machine, especially fertiliser broadcaster
Inventor: HIGGEN REINHARD
IPC: A01B73/06
Filed: 1987-10-03
Abstract: Distributor machine, especially fertiliser broadcaster, with a supply container and with distributor linkages, such as spreading booms or spreading worms, which project far beyond the supply container and to which the material located in the supply container is fed via a conveying device or metering device and which can be folded via joints up against the distributor machine into a transport position laterally or rearwards, the distributor linkages being held in the working position especially via clamping elements fastened to them, and being capable of oscillating about a horizontal axis pointing in the direction of travel. In order to eliminate these above-described disadvantages in a simple way, provision is made for arranging between the distributor linkage (213) and the frame (202) of the distributor machine locking elements (222) which take effect positively during the folding-in of the distributor linkage (213) and which are coupled to the booms (213) of the distributor linkage and can be controlled in such a way that, when the booms (213) are folded in, a position of the distributor linkage parallel to the frame (202) of the distributor machine is obtained (Figure 3). <IMAGE>

Title: Digital adaptive transformation coding methods
Inventor: BRANDENBURG KARL-HEINZ
IPC: G10L19/02
Filed: 1987-10-06
Abstract: A description is given of a digital adaptive transformation coding method for transmitting and/or storing acoustic signals and, in particular, music signals, in which method N sampled values of the acoustic signal are transformed into M spectral coefficients which are quantised and stored after being split up into frequency groups. The method according to the invention is characterised in that use is made of the quantised maximum value of each frequency group in order to describe the coarse variation in the spectrum, and in that the same bit number is assigned to all the values of a frequency group. Furthermore, the assignment of bits to the individual frequency groups is performed in accordance with the quantised maximum value occurring in this frequency group.

Patent DE-3819316-A1 (DE)
Title: Principle of multiplication and reduction of the torque of a torque lever
IPC: B25G1/04
Filed: 1988-06-07
Abstract: Each standard torque lever, when it is accompanied by a lever extension which embraces the screw nut or screw head at one end and at the other end forms the "head" of the torque lever and a lever, substantially increases the tightening torque of the nut, or conversely provides the given tightening torque and substantially reduces the required torque of the standard torque lever. In this way, with the appropriate modification of the design of the housing (not always, but only if necessary), an improved tightening action on the nut is obtained. Apart from the lever, which consists of the standard torque lever with extension, it is possible to design torque levers with screw mechanism which achieve a significantly greater action and hence also a much greater tightening torque than at present.

Abstract: By suitable control of the switching operation, the intention is, while avoiding voltage-limiting components, to avoid overvoltages which can be produced especially by vacuum switching devices in particular three-phase circuits. A tripping-control device (4) first causes switching off of a pole (phase R) of the switching device (2) at a time which excludes the creation of multiple restarts. Depending on the configuration of the mains, either the remaining poles (phases S, T) are opened together approximately 1.5 half-cycles later, or the remaining poles (phases S, T) are each opened at a separation of approximately 2/3 of a half-cycle one after the other.
