Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for the recovery of gas evolved from fermentation is disclosed.  The apparatus comprises a vessel containing the fermentation material, and a head slidably mounted on the vessel forming a substantially gas tight chamber therewith.  Mounted on the head are a series of projections of various shapes which extend into the chamber.          As the fermentation proceeds, the generation of gas causes the head to rise.  When it has risen a sufficient amount, a gas outlet valve is opened and the gas is introduced into a collector.  The reduction in gas pressure causes the head to drop.  The movement of the head causes the projections to break through the scum layer at the surface of the fermentation broth, thereby enhancing the reaction.  In a preferred form of the device, the projections are so formed as to urge the scum towards the discharge means, thereby breaking and removing the scum without the use of any additional energy.  A method for using the apparatus is also disclosed.

Circuitry is provided intermediate the respon-sive and detecting circuitry for preventing the response of the detecting circuitry for a limited time during and after a pacemaker stimulation signal.  In a preferred em-bodiment a reference level is established which is repre-sentative of sensed extraneous repetitive noise.

Abstract: ARRANGEMENT FOR SEPARATING AN OPTICAL               SIGNAL FROM AMBIENT LIGHT                       Abstract An arrangement for separating ambient light from an optical data signal, comprising an interference filter having a passband which matches the wavelength of the op-tical data signal, and two photo diodes which are so arranged that one photo diode receives the light trans-mitted through the interference filter, and the other receives the light reflected from the filter.  A variable aperture or an additional simple filter (5) is provided to adjust the transmitted and reflected portions of the ambi-ent light to one another.  Output signals of the photo diodes are subtracted from each other in a compensation circuit.  This results in compensation of the ambient light components so that an output signal from the com-pensation circuit only depends on the actual data signal.

Abstract: BIOCIDAL GAS STERILIZATION AND GAS      LEAKAGE DETERMINATION     ABSTRACT OF TEIE DISCLOSURE     The novel concept of, and methods and apparatus for, timely determination of potentially harmful biocidal gas leakage from a pressurized chamber during sterilizing operations are disclosed.  Biocidal gas make-up values are monitored during the sterilizing phase to provide prompt warning of biocidal gas leakage.  In one embodiment, the timing of preselected pressure increment gas make-up charges are measured and compared to minimum acceptable gas make-up charge times.  In addition, absorption of biocidal gas by the load can be compensated for in sterilizing operations where load absorption is a significant factor.  Also, provision is made for predicting gas absorption by the load from steam absorption data obtained during pressure-controlled conditioning cycles.

Abstract: ABSTRACT OF THE DISCLOSURE A multi-channel digital speech-synthesizer comprises a lattice filter simulating the vocal tract and generating speech samples by processing samples of periodic or random waveforms, supplied by respective generators, dependent on whether the vocal-tract configuration is in respect of a voi-ced or an unvoiced sound.  Such processing occurs on the basis of co-efficients supplied by an external unit which stores a set of parameters which characterize elements permitting the build-up of a dictionary that can be synthesized.  The para-meters comprise, besides the co-efficients, the duration of the respective validity intervals, information on whether the sound is voiced or unvoiced, the pitch period in the case of periodic excitation, and the intensity of the sound to be syn-thesized.  The generators and filter are connected with the external unit through a plurality of input modules, and a con-trol unit acting as an interface towards the external unit.          The input modules control the transfer of the parameters from the external unit to the generators, by requesting the external unit for a set of parameters at the end of each validity inter-val, temporarily storing the set of parameters, and updating the filter co-efficients at the beginning of every pitch period of a voiced sound, and at the beginning of a validity interval following an unvoiced sound.  The control unit is able to se-lect the input module for which the set of parameters is inten-ded and to store the requests for new parameters coming from the various channels and send them to the external unit.

Abstract: ABSTRACT OF THE DISCLOSURE A process for use in making bags from layered, coextruded film. The film can comprise a layer of HDPE (high density polyethylene) or PP (polypropylene) on a layer of EVA. Normally the HDPE layer cannot be heat sealed to the EVA layer. Both sides of the film are given a fairly high corona treatment. After treatment, a lap joint can be formed with the EVA layer abutting the HDPE layer, and the lap joint can then be heat-sealed together. The invention is also directed to a sleeve or bag made from layered, co-extruded film. One outer layer of the film forming the bag is made from HDPE, the inside layer from one of EVA (ethylene vinyl acetate), EEA, EMA (ethylene maleic anhydride) or EAA. The bag has a heat-sealed lap joint with the inside surface layer overlapping the one outer surface.
