Abstract: 1529106 Automatic exchange systems NORTHERN TELECOM Ltd 2 April 1976 [23 April 1975] 13469/76 Heading H4K A pcm conference circuit is arranged to deal simultaneously with a plurality of three or more party conferences, the circuit introducing a delay of two frames. An interface and control 10 extracts from the pcm highways of the system pcm speech samples in time slots concerned with conference calls and presents the speech samples over an 8 channel serial highway to the conference circuit in isochronous (interleaved bit) form, i.e. each channel comprises 32 bits, with the first bit of each of 32 pcm words being transmitted in channel 0, and the eighth bit in channel 7 etc. The conference circuit includes two 32 word, 8 bit, RAM memories I and II, one of the memories being fed with the incoming serial bit stream during one frame, whilst information fed into the other memory during the previous frame is being processed, the units MUX, 11, 11<SP>1</SP>, enabling the 32 speech samples to be stored in the RAM's in 8 bit parallel form. The processing frame of the conference circuit is divided into eight periods, period 0 not being used. During period 1 each 8 bit word in the RAM e.g. RAM1 written during the previous frame is used to address a read only memory 14 to convert the word into a 14 bit linear PCM word, and each linear word is added to a location of an accumulator 16 corresponding to the conference to which the word relates. During period 2, the 8 bit words are again supplied to address ROM 14, but with their sign bit changed such that a 14 bit word in 2's complement form is produced at the output of ROM, 14. This word is then added to the accumulator contents value for the corresponding conference (hence effectively subtracting the word of the subscriber) and the first 8 bits of the total are written into the location of RAM I corresponding to the read 8 bit word and the remaining 6 bits are stored in a corresponding location of an additional memory RAM III. The accumulator contents remain unchanged. During period 3, the 14 bit words stored jointly in RAM I and RAM III are converted back into companded 8 bit form using compressor 18 and are fed back into the corresponding locations of RAM I. During periods 4-7 RAM III and accumulator 16 are cleared, and in the following frame the contents of RAM I are read out via interface 10 to the subscriber time slots, thereby providing each subscriber of a conference with a PCM word representing the total speech of all the other subscribers of the conference. Where the number of conferees is between 6 and 12 the ROM 14 may be enabled to produce attenuated linearly coded words. The circuit may also be switched to a public address mode by causing the ROM 14 to produce words comprising logical 1's for all except a designated speaker.

Abstract: The generator controls the amplitude, the repetition frequency, the duty ratio and the waveform of the operating pulses applied to the operating gap. It has a circuit device which produces control signals (112, 113) from input signals (F, tp, P, A) which represent the electrical parameters of the operating pulses, which control signals (112, 113) represent an upper (16) and a lower (17) limit of the operating pulse waveform and control the power output stage of the generator. Curve shapes for the envelope curves (16, 17) of the operating pulses which have been found to be expedient for specific erosion processes are stored in programmed read-only memories. <IMAGE>

Abstract: A complete and reproducible process for producing novel strains of yeast, comprises making a first screening test and at least one other screening test selected from a group of screening tests which do not resort to any measurement of gas release, selecting by means of said first and at least one other said screening test the desired strains from a group of diploid strains prepared previously either by hybridation, or by mutation of existing strains. The tests are as follows: A first test consists of measuring the average multiplication coefficient of a given strain by following the optical density variation of a standard medium seeded by a suspension of cells obtained from this strain. A second test consists of measuring in the same manner the average multiplication coefficient of the said strain in the presence of an inhibitor acid added to the standard medium. A third test consists of measuring the maltose adaptation of said strain in the presence of glucose by determining the amount of maltose subsisting in a standard medium after a known amount of glucose added to this medium has been completely consumed. A fourth test consists of measuring the invertase content of said strain. A fifth test consists of measuring the latent time of said strain. The hybridation can consist of systematic haploid crossings derived from quick Saccharomyces Cerevisiae strains adapted to maltose and haploids derived from very slow strains not adapted to maltose, but well adapted to sweet doughs and sometimes also to acid doughs.

Abstract: A body preformed from a powdered material other than silicon nitride is surrounded with a casing, which is permeable to gas. The casing is transformed upon heating into a layer which is impermeable to the pressure medium which is used during isostatic pressing of the preformed body, while a pressure is maintained by a pressure gas outside the casing which is at least as high as the pressure of the gas present in the pores of the preformed product. When the casing has been made impermeable to the pressure medium and the preformed body has been enclosed therein, the isostatic pressing is carried out while simultaneously sintering the body. The casing may be a glass, metal or ceramic powder applied as a slurry or by flame spraying. The powders pressed may be Fe or Ni based alloys or Al2O3.

This can be avoided if the air of the freezing chamber is conducted through a first flow path having a motor driven fan and a filter and ambient air is conducted through the fan and the filter in a second flow path for regeneration of the filter. An arrangement for the purpose is characterized in that the filter is arranged in a first heat-insulated flow path, intended for freezing chamber air and containing a motor driven fan, that a second heat-insulated flow path, intended for ambient air, is connected to the first one before and after a part thereof containing the filter and the fan, and that valves are arranged for shifting of the flow paths.

Abstract: Wind propeller the blades (1) of which are permanently connected to a rotatably mounted hub (2). The invention is characterized in that the blades (1) of the propeller have a radially displaceable disc which, under the influence of a springing means (4) working between the disc (3) and the blade (1) or the hub (2) is kept in a first position relative to the hub (2) as long as the wind propeller remains motionless or rotates slowly. At an increasing rotary speed the disc (3) is successively displaced radially outwards from the hub (2) to a second position relative to the hub (2) by the centrifugal force counteracted by the springing means (4). The blade (1) as well as the disc (3) belonging to it has one or more through openings (5, 6) equally dispersed over the blade (1) and the disc (3) so that when the disc (3) is in the first said position it covers the opening or the openings (5, 6) in the blade (1) and vice versa, that is to say that the blade (1) and the disc (3) create a complete area of action for the wind. When the disc (3) moves towards the second position caused by an increased wind velocity said opening or openings (5, 6) in the blade (1) and the disc (3) increasingly coincide causing the area of action of the blade (1) to successively decrease at an increasing wind velocity.
