Title: Procedure for manufacturing a brake block
IPC: B29C43/20
Filed: 1983-01-25
Granted: 1986-12-10
Abstract: A procedure for manufacturing a brake block comprising a body (1) and a friction bit (5, 6), wherein the friction bit is pressed fast to the body (1) with the aid of heat effect so that the central region (6) of the friction bit will be softer than the margins (5) of the friction bit. The friction bit is pressed so that upon the body (1) are placed two friction material courses (5, 6) of different hardness material, the harder friction material against the body, whereafter the materials are pressed together and at the same time are pressed fast to the body in such manner that the harder friction material is freely allowed to flow into a widening in the lower part of the press. The harder friction material placed against the body will spread to the margins, whereby a friction bit is obtained which has a friction surface (6) with desired friction coefficient and harder margins (5), by which is prevented the ingress of abrasive foreign bodies in between the friction surface and the brake disk.

Abstract: The invention relates to a new process for the preparation of easy-flowing (flowable) oxytetracyclin hydrochloride. According to the process of the invention, the crude, dry or filter-wet oxytetracyclin hydrochloride consisting of needle-shaped crystals is boiled with an organic solvent forming an azeotropic mixture with water, optionally a part of the solvent is distilled off in a form of an azeotropic mixture, then the mixture is cooled and the precipitated oxytetracyclin hydrochloride consisting of spherical crystals is separated and dried. Oxytetracyclin hydrochloride exists in two various crystal forms, the one of which is needle-shaped, while the other one consists of orthorhombic sheets. The crystals of this latter form are capable of forming spherical particles by coalescence. The crystal form consisting of spherical particles is much more useful for the pharmaceutical industry. By means of the new process easy-flowing (flowable) oxytetracyclin hydrochloride can be prepared in a favorable yield and with a high purity from the crude hydrochloride product consisting of needle-shaped crystals.

Abstract: An on-chip memory control circuit generates a proper WRITE STROBE signal for a clock synchronized pipe-line operated integrated circuit memory. A symmetrical clock signal having half the frequency of the system clock is produced by applying the system clock to the C input of a standard master slave delay type flip-flop (2) having its Q output fed back to its D input. A negative going pulse train O/p comprising a pulse at every transition of the symmetrical clock is generated by a level change detector (4-24) which issues a pulse of a desired width whenever a level change at its input is detected. A delayed pulse train O/PD is produced at a delay (26) delaying phip an amount which depends on the speed of the memory and other design criteria. The pulse trains O/p and O/PD are applied to an asynchronous flip-flop (30), the output of which corresponds to the desired WRITE STROBE signal.

Abstract: An angiographic injector device for use in x-ray photography for delivering contrast media to a patient at controlled rates and pressures. A processor elicits injection parameters from an operator or a pre-programmed injection module, and on the basis of the injection parameters, calculates appropriate control signals for use in a closedloop servo system to actuate the plunger of a syringe containing the contrast media. Injection parameters include flow rate, volume, duration, pressure limit and rise/fall time of flow rate. The device also includes control circuits for inhibiting the injection device in response to a contrast media pressure limit, failure in the processor or injection control system, or upon reaching a predetermined volume of injected media. A mechanical stop member cooperates with the control circuit for blocking movement of the syringe plunger upon reaching the predetermined injected volume. Further, the device includes a self-test feature for checking the status of operational components thereof and a self-calibration feature for calibrating the servo system and position monitors. To improve reliability and to provide immunity from data corruption due to line power interruption, injection parameters are stored in battery-powered primary and secondary memories, and are compared and verified prior to an injection. To assist in coordinating an injection in synchronism with cardiac activity, the device monitors the ECG waveform of the patient's heart and injects a small bolus of contrast media at a given interval, such as the distolic interval. An interface also is provided for providing remote transfer of status and control information with the angiographic injector device.

Abstract: The present invention relates to the processing of phosphoric acid by crystallization. Wet-process phosphoric acid is purified by cooling it to supersaturated conditions and adding relatively large amounts of fine, relatively pure seed crystal. Crystallization thereafter proceeds under conditions which substantially favor crystal growth on the seeds which are added and disfavor secondary nucleation. To prevent the crystallizing magma from reaching a viscosity which would render further processing difficult, the present invention provides for recycling raffinate in an amount sufficient to maintain the solids content of the crystallizing magma below about 40%.
