Patent DE-2153786-B2 (DE)
Title: Fail-safe brake for trailers - with normal brake pressure holding off resvoir pressure from brakes
IPC: B60T15/24
Filed: 1971-10-28
Abstract: The trailer brakes operate as pneumatic servo hydraulic systems in which pneumatic pressure is used to drive the servos. The brakes are further fitted with a fail-safe valve which balances the operating pressure against the reservoir pressure, using a stepped piston. If the brake system pressure falls due to leaks etc. the operating the brakes connects the reservoir pressure directly to the servo and applies the emergency brakes. The brakes operate rapidly on the trailers so that they do not overrun the towing unit. The system is an improvement on existing designs in which the driver has to provide an extra large pedal force before the emergency braking is initiated, resulting in overbraking of the towing unit.

Title: Electronic audio delay network using shift registers - involves analogue digital conversion techniques to produce signal delay
IPC: G01H7/00
Filed: 1971-11-10
Abstract: A delay network is used in audio engineering applications when typically a delay equivalent to that produced by a direct audio path through air is required. The system is economical in its use of circuits compared with traditional methods. The audio signal is transduced via a microphone, filtered and amplified and applied to an analogue-to-digital converter producing a twelve bit output. This is fed to a nine stage shift register based delay line. The output of this is fed to a digital to analogue converter, to an amplifier, and thence to a low pass filter and output amplifier. Noise suppression circuits are also incorporated in the arrangement.

IPC: G10L19/038

Abstract: PURPOSE:To improve the coding efficiency by setting a permissible distortion to a distortion decision circuit and applying variable length coding to an index signal of an output vector when the distance (distortion) between an input vector and an output vector is a permissible distortion or below during an output vector retrieval of minimum distortion so as to obtain a coded output. CONSTITUTION:A distortion d1 between an input vector (x) and an output vector y1 and a set permissible distortion dtheta are compared and when the relation of di<=Dtheta is reached, the retrieval is stopped. Then an index signal (i) of the output vector at that time is subject to variable length coding to obtain a coded output. thus, the coding efficiency is improved remarkably and high speed processing is attained.

Abstract: PURPOSE:To easily obtain a regenerating signal having a good quality, which is brought to tangent approximation, by integrating a ratio of an amplitude value in digital data and a value showing a sampling period, and executing interpolation of a signal. CONSTITUTION:For instance, a voice is converted to an electric signal by a microphone, and thereafter, is sampled by a sampling period of an A/D converter ADC, and its amplitude value is quantized. It is controlled by a controlling circuit CCT, and is stored in the second memory M2 as data consisting of a group of the amplitude value and information related to a zero point interval. In case of regeneration, this data group is read out and is provided to a D/A converter DAC, the digital amplitude value and the information related to the zero point interval are converted to an analog value, and a signal is applied to an interpolating circuit CP. The interpolating circuit CP consists of a divider and an integrator, and by the divider, a ratio of the amplitude value of the analog value and the information related to the zero point interval is calculated, and its output is integrated by the integrator, and is made approximate to its original AC signal by tangent approximation.

IPC: A61M37/00
Filed: 1988-03-16
Abstract: An electro-osmotic transdermal drug delivery system for passing a drug to the systemic blood of a patient through the skin (16). The delivery system includes a semi-dry drug patch (24) containing a water solute with the drug and a selected level of current delivered to the semi-dry patch (24). Water from the semi-dry patch (24) is limited in movement from the patch to the skin (16) particularly in lateral movement relative to the skin so that the sweat and sebaceous ducts (30) and glands (32), which ordinarily are filled with liquid, namely the solute, and act as electrical shunts for osmotic delivery of the drug, are starved of liquid so that the electrical current is diverted to the stratum corneum (28) along with the electro-osmotic movement of the liquid carrying the drug (24). This result greatly increases the total drug delivery area of the skin. In addition, because the current need not be kept at a low level to avoid irritation or damage to the skin shunts, the current of the invention can be significantly elevated so as to overcome the higher resistivity of the stratum corneum (28) to the passage of liquid and current. A current conditioner such as an oscillator can be added to the system so as to break the liquid column within the skin shunts at periodic time intervals in accordance with the natural replenishment that will occur at relatively long time periods.

Abstract: The polymerization of alpha-olefins in a gas phase involves the problem of agglomeration of the product into particles disadvantageous from the viewpoint of its handling. In the present invention this problem has been solved by means of a new type of process for the homo- or copolymerization of alpha-olefins. In the process the catalyst system is pretreated by contacting and reacting a transition-metal compound which is solid or on a solid carrier with an organoaluminum compound, and possibly an electron donor, in a liquid medium, and by drying the thus formed reaction product to produce a solid catalyst system. The thus pretreated solid and active catalyst system is then fed together with an alpha-olefin in the gaseous state into a gas-phase reactor, and polymerization is carried out by contacting them with each other. By feeding a dry and active catalyst system into the gas-phase reactor, it is possible to avoid the agglomeration of the product which occurs in conventional processes in which an organoaluminum compound and possibly an electron donor are fed in a liquid medium into the reactor.
