Abstract: In order to improve carcass quality and food conversion efficiency of an animal, an exogenous synthetic porcine growth hormone (or analogues, derivatives, or fragments thereof) is administered to the animal at a preselected liveweight and at a preselected constant dose rate depending on the sex of the animal for a preselected period. For example the exogenous synthetic porcine growth hormone may be administered initially at a liveweight of approximately 35 to 100 kg when the animal is a pig. When the pig is a female or a castrated male, the dose rate may be approximately 0.06 to 0.10 mg/kg liveweight/day. When the pig is an entire male, the dose rate may be approximately 0.01 to 0.15 mg/kg liveweight/day. The growth hormone may be administered at an increased dose rate for a further preselected period.

Abstract: A duplicate recording system uses video cassettes for storing master library recordings. On both the recording and the duplicating ends of the system, all signals are buffer stored in an electronic memory while the signals are in a digital form. This buffer storage completely isolates the recording/reproducing steps so that the usual parameter of restraints disappear. For example, the duplication ratio may be any value within the capabilities of the recording/reproducing machines. This isolation eliminates expensive setup procedures heretofore required to switch from one to another duplicating ratio. The buffer storage also provides a more precise transfer with greater fidelity of the recorded signals. A computer calculates a smoother analog curve when the digital-to-analog conversion is made.

Abstract: Halide-containing residues from waste gas purification are, if they have a content of water-soluble constituents, virtually unutilisable and can be put into landfill only with restrictions. As a result of the novel process, the constituents which can be eluted with water are incorporated into a mineral matrix in such a way that a markedly reduced susceptibility to elution is obtained. It also becomes possible to convert the residues into a product which can be used as a hydraulic binder. The halide-containing residues are, as constituents of a raw meal for the manufacture of chlorosilicates, subjected to a thermal treatment.

Abstract: To be able to measure an electrical three-phase system with respect to the amplitude of its currents or voltages and with respect to the phase shift between currents and voltages by means of conventional oscilloscopes, the invention provides for converting the three-phase system into a two-phase system and to apply its two phases to the horizontal and vertical deflection input of the oscilloscope and to check a voltage phase in the case of the measurement of the current phases and a current phase in the case of the measurement of the voltage phases of the three-phase system for the occurrence of a predetermined phase angle and, every time this phase angle is detected, to generate a marking pulse which is applied to a brightness or colour control input of the oscilloscope. As a result, a circle is displayed on the oscilloscope when the amplitudes of the three phases are of equal magnitude and on the circle a mark of varying brightness or colour is displayed, the radius of the circle corresponding to the amplitude and the angular position of the mark corresponding to the phase shift between voltage and current of the three-phase system. <IMAGE>

Abstract: To process picture data, especially for still picture transmission, picture data are in each case transformation-coded by sub-picture areas in a plurality of passes and the coefficients obtained are selected for transmission according to their significance. In each pass, finer quantisation and selection of a larger number of coefficients are carried out. The picture data obtained from each pass of the processing are used to process subsequent pictures if the content of the subsequent pictures has changed only slightly compared with the previously processed picture. The DC coefficients already undergo definitive fine quantisation in the first pass and are not further improved in the subsequent passes. <IMAGE>

Abstract: The largely automatic resetting of the brake linkage of brake devices, in particular of shoe brakes for railway vehicles, takes place usually by means of single-action or double-action linkage actuators at the start of the associated brake linkage chains. In the case of longer brake linkage chains, the resetting can no longer be compensated solely by the linkage actuator and the positions of the brake levers at the end of the chain can become so unfavourable that adequate functioning of the brake device is no longer ensured. So that additional manual resetting of the brake linkage can be largely dispensed with and the efficiency of the brake device improved, in a brake device of the generic type at least one further linkage actuator is arranged in series in the brake linkage chain behind a forward-mounted linkage actuator. The required resetting path for the linkage actuator which is respectively mounted downstream is determined by the control stop which is coupled relatively to the forward-mounted linkage actuator limit point. The control stop of the respectively forward-mounted linkage actuator is arranged so as to be longitudinally displaceable on the frame in relation to the linkage actuator and is connected to the linkage actuator which is arranged after it. <IMAGE>

Abstract: In nonlinear optimization a plurality of optimization methods are stored (100) in a computer system as are techniques (101,102) (knowledge) for applying those methods. Such techniques may be divided into common knowledge (101) which are techniques applicable to all nonlinear optimization methods and domain knowledge (102) which are techniques applicable to a corresponding one of the methods. When an optimization problem is input (103) to the computer system, the system first selects (104) one of the methods and applies it (108) to the problem using the common knowledge and any relevant domain knowledge. If that method does not produce an optimum result, the system tries to solve the problem with another method, again making use of the common knowledge and the respective domain knowledge. This process is repeated until an optimum solution is obtained. The method is applicable to computer control of industrial plants and systems and to computer aided design.

Abstract: A recording-reproduction device is provided with at least one pair of recording-reproduction heads and a plurality of pairs of variable speed reproduction heads, which divides up and records onto a plurality of tracks video signals for one field and conducts reproduction of the video signals recorded on the tracks. The height disparities between the paired heads of the variable speed reproduction heads are set to three times the height disparities of the recording- reproduction heads so that image signals corresponding to horizontal scanning lines appearing at nearly regular line intervals on a reproduction screen can be reproduced from the tracks. The device comprises a reproduction processing circuit which obtains video signals for a variable speed reproduction whose video signal band is compressed by causing at least one of those setting conditions of the field frequency, the number of horizontal scanning lines and the horizontal scanning frequency for video signals to be reproduced to vary with the setting conditions relating to the video signals recorded on the tracks. Accordingly, it is possible to form a pictorial image possessing a picture quality sufficient for the performing of search using only a part of the recorded video signals. The device is further provided with a simplified monitor for   displaying a pictorial image based on the video signals for the variable speed reproduction at the tide of variable speed reproduction.
