Title: Machine tool clamping sleeve - has two conical faces and is driven in collet sleeve by nut
IPC: B23B31/02
Filed: 1975-06-12
Abstract: A machine tool spindle has a clamping arrangement as in the main patent with a split clamping sleeve (217) so that its bore can be reduced when it is driven into a collet sleeve (215). The clamping sleeve has a first conical section at its end and a second conical section on a rim on its outside diameter. Both conical sections engage with conical bores in the collet sleeve. A grub screw (247) mounted in the collet sleeve engages a cut-out in the clamping sleeve and prevents it from rotating. A sleeve nut (255) is screwed over the outside of the collet sleeve. A collar on this sleeve nut engages with the rim on the clamping sleeve. The nut drives the clamping sleeve against the conical bores in the collet sleeve, so that the clamping sleeve will close over a spindle mounted in it.

Title: Thermal processing of high ash bituminous solid fuels - by low temp. carbonisation, gasification and combustion of residue
Inventor: PONOMAREV JURY VASILIEVITSCH
IPC: C10B49/20
Filed: 1975-08-25
Abstract: The gasification residue passes the after-combustion sauge in an aero-eruption condition and the hot ash with the flue gases is discharged as an aerosol. A share of the aerosol contg the fine ash fraction is used to control the consumption of heat transport medium. This eliminates the imperfect after-combustion of polydisperse gasification residue with a low content of combustible matter in a fluidised bed. Environmental pollution by fine particles emission is reduced and coarse fractions are utilized as heat transport medium.

Title: Return to zero stage for signal regeneration - allows input to be scanned and output of same period as clock generated if threshold valve is exceeded
Inventor: BOEDEKER FRIEDRICH ING GRAD
IPC: H04L25/24
Filed: 1975-10-28
Abstract: A return to zero function for signal regeneration is provided by digital transistor switching stages. A transmission signal is periodically scanned and if the amplitude exceeds a threshold value during the Scan period, then an output is generated. The output signal (W) is a function of the states of three transistor stages (T2, T4, T5) and is in the form of a positive square wave pulse corresponding to the period of the applied clock signal (T). Additional transistor stages (T1, T3, T6) provide coupling with the output (Q) to define the scan periods which are generated immediately the clock signal goes low. If during the scan period, the input is below the threshold, then the output remains at zero.

Inventor: FORMAN LADISLAV DIPL ING
IPC: C12N1/16
Filed: 1975-12-18
Abstract: In prodn. of a protein concentrate by aerobic culture of yeast on whey, sweet or sour whey, or sweet whey fermented to is not >1.6 wt. % lactic acid by Streptococcus or Lactobacillus culture at 18-50 degrees C under anaerobic conditions, is boiled to coagulate foam-forming substances, cooled to 26-34 degrees C, brought to pH 4-6 by addn. of CaCO3 in presence of mineral nutrients, e.g. NH4, K or Mg salts, and of urea and ethanol.

Title: Bypass through refractory lining of process vessel prevention - by flexible metal discs embedded in refractory mortar
Inventor: DUERRFELD RAINER DIPL ING DR
IPC: B01J19/00
Filed: 1976-02-04
Abstract: A device for preventing bypass flows through the internal thermal insulation of a reactor vessel through which gas flows in a high temperature process consists of separating discs incorporated at intervals along the length of the vessel and within the internal insulation. These discs are connected to the reactor vessel wall in a gas tight manner. The discs are of metal foil, embedded on both sides in a refractory mortar. Used for any high temperature process vessel, such as a reformer, converter, combustion chamber or coal gasification plant. In particular where the internal gas flow resistance within the vessel is so high that a bypass will tend to form through the porous, refractory insulation particularly if a crack occurs. By making use of a thin, flexible foil, the arrangement ensures that it does not become cracked by the thermal movement of the refractory lining relative to the vessel wall.

Title: Identification plate serial number stamping machine - has multi disc stamping wheels operated by rack and pinion mechanism
Inventor: OSTROWSKI OSWALD
IPC: B44B5/00
Filed: 1976-03-19
Abstract: The machine for marking serial numbers on identification plates (31) for motor vehicle components has an upper numbering wheel (2) which may be a female mould or matrix member, and a lower numbering wheel (3) for the male mould, each wheel consisting of a side by side set of discs (4, 5) mounted on a spindle (7, 8).

Each frame is in turn actuated by a set of horizontal rods (12 to 15) which move forwards or backwards. The numbering wheels are also raised and lowered to carrying out their stamping action on the plates (31).

Patent DE-2620767-A1 (DE)
Inventor: EHRAT KURT DIPL ING
IPC: G07D7/12
Filed: 1976-05-11
Abstract: To judge the printing quality of bank notes, the image content of which is composed of part images originating from different printing processes, for example offset and intaglio printing, a plurality of originals Dr, Do according to the number of printing processes involved are used, each of these originals containing only one part image from one of the printing processes. The originals are then combined by means of optoelectronic scanning (3, 4, 5, 6, 7) to form a total image, the relative positions of the individual image spots of the part images on the part originals being determined and also being taken into account. This artificial total image (Dp) is then compared in spots with the likewise optoelectronically scanned testpiece, again taking into account the relative positions of its image spots in relation to those of the original spots. The judgement is then made by evaluating the results of this spot comparison according to specific error-evaluating methods.

Title: Delayed action seat belt release mechanism - has clockwork driven locking plate releasing cam only when release of belt is desired
Inventor: SULZER OTTMAR
IPC: B60R22/32
Filed: 1976-05-19
Abstract: The locking plate (21) is hooked into the slot (19) of the lock counter part (18) hinged by pins (17) to the slidably arranged plate (12). The locking plate is kept in locked position by lip (20) resting against the forward edge of the hinged counterpart (18) and by pins (25) resting against the tip of cam (3). The slidable plate (12) is kept in place by a spring loaded ball (10) up to a certain pre-adjusted tensional force. When, in case of an impact or deceleration this force is exceeded, plate (12) slides forward, whereby pin (25) clears the tip of cam (3), which under the action of a clockwork starts rotating anticlockwise until its tip (27) comes to rest against the underside of a hinged counterpart (18) and forces it to perform a pivoting motion whereby lip (20) can slip out from the slot (19).

Title: Weighing machine digital data transmitter - uses coding pulse preceding or following counting pulses to indicate sign of measured value
Inventor: BECKER MANFRED
IPC: G01G23/37
Filed: 1976-06-16
Abstract: The system for transmitting data derived from weighting to a remote indicator station entails the conversion of the analog values from weight measurement into a digital form. The design ensures a trouble-free and rapid transmission in a simple form together with the indication of sign, overload, calibration state and other characteristic values. This is achieved by forming a coding pulse whose length is proportional to the sign of the derived measurement value and/or other characteristics of the operation. The measurement output voltage and the ramp or sawtooth voltage from oscillator (1) are fed to comparator (3) which drives control circuit (4) connected to master oscillator (5) and up-down counter (6) of memory (7). This results in the division of the measurement cycle into a sensing phase and a calibration phase by connecting a reference voltage through switch (10) and feeding the measurement output voltage through switch (11). The counting pulses are transmitted to decade counter (23) via master oscillator (22) and this is followed by a flip-flop (24) for indicating the sign using decoder (20).
