Title: Rotary furnace with circumferentially arranged cooling tubes - connected to the furnace body using anchorages and bellows type compensators
Inventor: HEINEMANN OTTO
IPC: F27B7/40
Filed: 1974-03-15
Abstract: To allow for longitudinal expansion of the cooling tubes and at the same time to achieve a safe anchorage of the rotating tubes a two point support is provided for each tube which allows limited longitudinal expansion of the tube but ensures a rigid fixing in radial direction. The compensating part of the arrangement can be of the undulated type or acute angle bellows. Alternatively, the compensating part can be formed by a set of elastic spokes fitted between the cooling tube and the anchorages. The anchorages can be positioned in such a way that in cold condition of the furnace a certain pre-stress is exerted onto the anchorage, which disappears when the furnace is in operation.
Patent DE-2414011-A1 (DE)
Title: Monitor for sub-units controlled by pulse trains - has reversible counter and can be engaged by other devices
Inventor: EICHNER ERICH
IPC: G06F11/277
Filed: 1974-03-22
Abstract: The counter is, in the sub-unit free state, driven by a special pulse train to one of its end positions, where it delivers an evaluation signal. Logic switches prevent in the sub-unit free state retransmission of this evaluation signal as an alarm signal, and generate an alarm signal when the evaluation signal is missing. Thereafter the logic switch output signal which generates the alarm signal in the subunit free state, passes through a timing circuit which retransmits only input signals of a specified minimum duration sufficient for the counter to be driven by the special pulse train pulses to one of its end position.
Patent DE-2414216-A1 (DE)
Title: Granulated lambda-sulphur for process industries - made using mixt. of sulphur, mineral oil and fine silica

The pref. conditioner is 0.2% "Aerosil" which may form a surface layer on the granulate, and the pref. mfg. process consists of mixing the sulphur, conditioner and the mineral oil in a counter-current high speed mixer for pre-granulation followed by the use of a conventional granulating appts. such as plate; in the pre-granulation stage, pref. 10-30, esp. 20% of the mixt. is converted into a granulate with size 1-3, esp. 2mm. The sulphur granulate is used in process industries, esp. for rubber. It is in an inexpensive granulate form which can be stored, conveyed and dosed without the formation of dust, electrostatic charges or lumps.

Title: Data storage of visual information - output of gamma ray scanner is selectively displayed using light pen sensor location
Inventor: PETER FRITZ ING GRAD
IPC: G06F3/033
Filed: 1974-04-17
Abstract: The technique of using a radio active source for the diagnostic medial analysis of body organs utilises a gamma ray camera or scanner that monitors levels at different points. The signals are stored in a memory matrix and may then be selectively transmitted to a television display. The digital store outputs are coupled via digital to analogue converters coupled to aynchronising circuitry transmitting to the display. A binary counter provides a time base for the system. A light pen sensor is used to locate a specific points in the main store. Each 128 bit column in the matrix provides a facility for 5 bit display in the region of interest by actuation of 5 keys.

The axes of one pair can run parallel to the latter and alie in a common plane at a distance from that of the other pair. The drum axis can be horizontal.
Patent DE-2424077-A1 (DE)
Title: Signal transmission method using light - digital binary signals converted at sender into bright-dark signals
Inventor: MATT HANS JUERGEN DIPL ING
IPC: H04B10/00
Filed: 1974-05-17
Abstract: The signal transmission system has the bright-dark signals reconverted in the receiver by a photoelectric transducer into electric signals. Only level changes of the binary signals are converted at the sender into short light pulses. Electric pulses delivered at the receiving end by the photoelectric transducer are applied to a bistable flip-flop tripping input, so that the flip-flop changes its state at each pulse and delivers at its output the original signal. An SC laser is used in the sender at the electro-optical transducer, and an avalanche diode is used in the receiver as the photoelectric transducer.

Filed: 1974-08-23
Abstract: Device for controlling a multi-strand continuous casting plant where a tundish with several bottom holes feeds several chilled moulds from which the hillets are drawn and either worked or not worked prior to cutting to length. For each strand, a timer is provided with a variable resistance combination for adjusting the billet length, and guide-rolls on the billet drive a tachogenerator providing a control voltage proportional to the billet speed, the voltage being fed to the timer which is also linked to a pulse-generator controlled by the shearing device which generates a starting pulse; and on the output of the timer is a switching amplifier which is self-locking and generates a periodic control signal sequence which determines the closing time of the outlet nozzles on the tundish. Optical and acoustic signals are pref. included. Provide optimum distribution of the metal in the tundish where the stoppers are closed w.r.t. time so that only the last part of the last billet is an undersize length.

Title: IC engine with stratified charge - weak mixture only is inducted during first inlet stroke phase
Inventor: KRUEGER HERMANN DR ING
IPC: F02B19/10
Filed: 1974-11-11
Abstract: The cylinder head is provided with an outlet valve (4) and an ignition chamber (8) separated by a step (6) from the main combustion chamber (7). The ignition chamber contains the spark plug (5). A fuel mixture channel (9) containing a pure air branch pipe (10) leads to the inlet valve (4) and contains a poppet valve (11) which is timed to open and close in the sense that additional air is admitted to dilute the fuel mixtures drawn in via the open main inlet valve (4) at the start of the induction stroke. The result is that a weak mixture is formed close to the piston and a rich mixture is formed close to the ignition chamber which is not appreciably weakened during the following compression stroke.

Title: Purification of insulin by gel filtration - using an alkali metal or ammonium insulin
Inventor: JACKSON RICHARD LEE
IPC: C07K14/625
Filed: 1975-02-07
Abstract: An alkali metal or ammonium insulin (I) is purified by adding to a column packed with a swollen gel having in the dry state a water regain of at least 4 wt. % and particle diameter smaller than 100 microns an aq. soln. of (I) of at least 80% purity, of concentration about 1-8% (w/v) and pH about 2. 0-3.5, to provide a column loading of about 0.8-6.7 g/1 of bed volume, and eluting the insulin from the column at about 5 degrees-30 degrees C with an aq. eluant having a pH in the same range as the insulin soln. by the present gel filtration, insulin having a higher purity than that obtained in similar prior art procedures is obtained. The product is usually subsequently converted to zinc insulin which may be made up into various pharmaceutical forms of insulin. Also the purer zinc insulin permits the prepn. of a neutral insulin which is more stable than acidic insulin; it also permits the formulation of extended action pork and beef insulin preparations without additional purification as was required in the past; further it permits the prepn. of isophane insulin using less protamine.
