Patent EP-0327059-A2 (EP)
Inventor: HENDERSON STEVEN
IPC: B22D11/10
Filed: 1989-02-01
Abstract: A method of removing heat from molten metal in which the metal is caused to flow freely within a gaseous media or vacuum over a body disposed within the metal stream such that any tendency for the metal to solidify during its passage is effective on the surface of said body against which the solidifying metal contracts into intimate contact herewith. The body may be forcibly cooled e.g. by water. 
     In accordance with this invention since the liquid metal is not enveloped by a channel (7) or pipe the solidifying shell tends to shrink on to the body, no gap is created as hitherto and accordingly much higher heat transfer coefficients between the shell, and thus the liquid metal, and the cooling body are achieved.

IPC: G01F1/20
Filed: 1989-07-25
Abstract: The upwardly extending outlet of a pump contains a non-floating permanent magnet which tends to assume a lower end position but is propelled upwardly in response to admission of a metered quantity of liquid into the outlet to initiate the emission of a signal by a sensor. The emission of such signal persists as long as the actuator remains above its lower end position. The sensor is connected with the resetting input of a counter by way of an OR circuit. The n-th output of the counter transmits a signal to an alarm signal generating circuit in response to transmission of a certain number of consective timing pulses to its counting input prior to transmission of a signal to the resetting input. The timing pulses are transmitted by a generator which also transmits pulses to the pump to thus determine the frequency of admission of liquid into the outlet. A rectangular wave oscillator receives signals from the sensor and transmits a series of signals to the OR circuit with a delay which equals or approximates the length of the interval between two consecutive timing pulses. The oscillator starts to transmit signals to the OR circuit only if the signal which is emitted by the sensor persists during the aforementioned delay. This ensures that no alarm signal is generated if the viscosity of pumped liquid is so high that the actuator is incapable of returning to its lower end position during the interval between successive admissions of liquid into the outlet.

Abstract: In a radio-frequency receiver with a device for indicating the transmitter names, transmitters are also to be indicated which do not radiate any additional signals containing the identification data. For this reason, tables in which each transmitter site is assigned the associated frequency, the transmitter name and a list of those transmitters which can be received at this transmitter site are stored in a digital memory. Furthermore, there is a microprocessor which - tunes the receiver to a strong transmitter radiating additional signals containing the identification data (RDS transmitter) and determines its frequency and its name, - determines from a first and from a second table the transmitter site belonging to the frequency and the name of this RDS transmitter, - determines from a third table all sites assigned to the site of this RDS transmitter, - finds from the first table among these sites the site of which the associated frequency corresponds to that of the unknown transmitter, and -determines from the second table the name belonging to this site and supplies it to the display device.

Abstract: A video signal from a low impedance output of an amplifier device (41 or 42) is conveyed to an image display device (35) via a coupling path including first (52) and second (28) series connected resistors and a high frequency bypass capacitor (54) coupled across the first resistor.

Abstract: The present invention provides a method capable of lining a multibranch piping with a coating material within the pot life of the coating material without leaving uncoated area or excessive repeated coating. Lining for a main pipe is performed by pouring the coating material into the main pipe (1) from an end portion of the pipe, and lining for branch pipes (10) is effected by the feed of the coating material and air for each of the branch pipes. A completed time point of lining in each branch pipe is detected by any of the following methods:
     A) A method wherein the time required for lining a branch pipe is estimated in advance and upon lapse of the estimated time it is judged that the lining for the branch pipe was completed.   (B) A method wherein a change in gas pressure in the main pipe which occurs upon arrival of the coating material at the connection between a branch pipe and the main pipe under the feed of air is detected by a pressure gauge, whereupon it is judged that the lining for the branch pipe was completed.   (C) A method wherein when the coating material fed from an end portion of one branch pipe was discharged from   another branch pipe located in a position close to the one branch pipe, it is judged that the lining was completed.

Abstract: A video recorder has a drive (10) for driving a video magnetic tape, a tape sensing device (11) and a drive control device (13). The latter has an automatic operating mode, in which it allows the recording of video items only from tape positions which lie an integral multiple of a fixed-predetermined tape section value behind a tape recording beginning. The fixed-predetermined tape section value is, for example, two hours. This has the consequence that the video tape is divided into tape sections of two hours playing length in each case. The video recorder moves exclusively to the beginnings of these tape sections when video items are to be recorded. The titles of the video items recorded are indicated to the user on a screen in a list in the order in which they are recorded. At the end of the list there is displayed how many tape sections are still free. If the user sees that tape sections are free and he wishes to record a video item, he gives the video recorder a corresponding instruction. The video recorder then automatically searches for a free tape section. <IMAGE>

Abstract: (57) An adaptor affixing a video camera to a film camera. The adaptor permits the transmission of the Image formed on the focusing screen of the latter to reach the former In a correct loft-right and up-down orientation. For this purpose, it utilizes a mirror which, in one position, transmits the Image to the video carriera, In the other, It permits the viewing of the image on the film camera's focusing screen with or without magnificatian. Nonatheoless, it permits visual and manual access to the normal controls of the camera. A shield prevents the access of light not from the film camera's image to the video camera for a sharper and clearer image. The adaptor attaches to the usual coupling devices of the film camera which generally permits the affixing of photographic accessories. To permit a more compact system, the adaptor bends the light path from the imagé screen to the video camera through an angle greater than 90 degrees but not greater than 180 degrees. For a single lens reflex camera, this angle may amount to 130 degrees. For a view camera, the light path bends 180 degrees.
