Abstract: Gellation resistant aqueous glycol compositions and stabilizers for inorganic silicate corrosion inhibitor additives in antifreeze/coolant formulations are described. The stabilizers have the structure
     where n is an integer from 1 to 20 and R is a solubilizing agent. The solubilizing group may be a cyano-terminated group, a diol ether group, an acid group, and amide group, a group which will yield a diol on hydrolysis, among others. These stabilizers help prevent the inorganic silicate additives from precipitating out and thus extend the shelf life of antifreeze formulations into which they are incorporated.

Abstract: Packing containers with fold-out pouring spout are used for a great number of beverages, e.g. milk. The pouring spout comprises a number of connected triangular wall panels which are delimited by folding lines. On opening the pouring spout is folded out and the packing container is opened in that an outer end of the pouring spout is removed. To prevent the pouring spout from reverting to its folded-in condition after the opening the folding lines which delimit the material panel of the pouring spout from the upper side of the packing container are arranged so that they run at unequal angles. In this manner the breaking open and the forming of the pouring spout are facilitated.

Abstract: An acoustic processor and a method of processing an acoustic wave input which includes a non-linear auditory model of the neural firing rate in the ear. The firing rate is determined by the replenishment of neurotransmitter and loss of neurotransmitter due to spontaneous decay, spontaneous firing, and acoustic wave inputs defined, preferably, in sones. The number of free parameters in the acoustic processor is reducible to one, namely the ratio R of two steady-state firing rates each resulting from a different loudness. Preferably, the free parameter is adjusted to minimize steady-state effects which are adversely impacted by speaker differences, background noise, distortion, and the like. The present invention addresses the general problem of processing an acoustic wave input in a speech recognition system and addresses the specific problem of adjusting acoustic processor performance to reduce adverse effects.

Abstract: When excessive acceleration slip of a driving wheel is detected by wheel speed sensors attached to driving and non-driving wheels, an electronic control unit provides first and second control signals to a change-over valve and a control valve, respectively. The change-over valve operates in accordance with the first control signal to supply hydraulic pressure from a hydraulic pump to control cut-off valve to thereby cut off communication between a master cylinder and a wheel cylinder. At the same time, hydraulic pressure from the hydraulic pump is fed to the wheel cylinder through the change-over valve and the control valve to brake the driving wheel. The control valve operates in accordance with the second control signal to increase or decrease the pressure in the wheel cylinder thereby adjusting the braking force for the driving wheel.

Abstract: It is well-known that in case a bearing seal is subjected to severe circumstances e.g. splashing mud and water, to execute the sealing lip in such a way that it rests with high contact forces on its counterface. Higher friction will be generated and consequently higher temperature and wear. These disadvantages are obviated by the claimed seal arrangement which is characterized in that at the outside of the seal (14) a stiff shield (8') is applied which in sectional view is mainly L-shaped. The shield (8') with its short leg (9') is fixed on the bearing inner-ring (1'). The seal lip (16) rests on a supporting ring (10') of shield (8'). The improvement consists therein that between a bearing ring part (11') and end-part of shield (8') a split (12') as well as between shield (8') and seal (14) a space (13') are both present. Due to this arrangement and under influence of centrifugal forces contaminated liquid are circulated in said space (13') to the outside of the bearing via said split (12') forming a sealing by itself as tests have shown.
