Title: Method and casting mould arrangement for the controlled cooling of castings
Inventor: BERG CHARLES ADOLPH
IPC: B22D27/06
Filed: 1981-06-16
Abstract: The invention relates to a casting method and a casting mould arrangement for the casting of large metal parts, such as ingots and the like, the aim being to avoid the formation of sink holes on the free surface. For this purpose, a hood is, according to the invention, placed on the open end of the mould, and provided in this hood is a diaphragm which intercepts the radiant heat emitted by the surface of the metal and reflects it back onto the latter. It is advantageous here if a reflector or a series of baffles is provided behind the diaphragm to ensure that the heat radiated from the rear side of the diaphragm is reflected back onto it. The hood can have cooling arrangements for the reflective surface and devices for producing a vacuum in the casting mould arrangement. Insulation can furthermore be provided at the upper end of the casting mould to prevent heat dissipation. Finally, it is possible to provide devices which allow the supply of heat to the free surface of the casting. <IMAGE>

Title: Method and appliance for determining the presence of traces of fluorescent materials precipitated on a surface of pane-like objects oriented in a particular direction while they are being shaped
Inventor: MCCOMB WALTER DAVID
IPC: G01N21/64
Filed: 1981-07-07
Abstract: The invention relates to a system for testing the surface of a glass pane which, during its manufacture by the float process, is supported in a floating manner on a molten bath and on its lower surface carries traces of fluorescent metals or metal oxides. The test system employs an appliance for scanning for the presence of a glass plate and for activating an ultraviolet light which is modulated and irradiates the surface of the glass panes. A detector responding to visible light detects the fluorescence of the irradiated pane surface and generates a signal which is processed by an electronic circuit to indicate the presence of metal oxides on the pane surface. If fluorescence is detected, the ultraviolet light is switched off, and if no fluorescence is detected, an alarm is triggered. <IMAGE>

Title: Manual starting crank device for internal combustion engines
Inventor: HATZ ERNST DIPL ING
IPC: F02N1/02
Filed: 1981-07-29
Abstract: The invention relates to a manual starting crank device for internal combustion engines with a manual crank and a starting crank journal which can be coupled to the engine element to be turned by means of a carrier connection releasable in the direction of the axis of rotation, at least one drag element being connected to the starting crank journal, which element slides freely on the slideway fixed to the housing when the starting crank journal is turned in the starting direction but when turned in the opposite direction is held by the slideway and forced into a relative movement increasing the distance between slideway and swivel axis of the drag element and releasing the carrier connection. It is the object of the invention to create a starting crank device which is on the one hand cheap to manufacture and on the other reliably protects the operator against kickback of the hand crank during operation. This object is met in that the form and position of each drag element is selected in such a way that when the starting crank journal is turned in the opposite direction self-locking occurs between slideway and drag element. The carrier connection is thereby released and the hand crank freed. The arrangement is shown in Fig.1 of the enclosed drawing of the application. <IMAGE>

Title: Flow-rate regulator for liquid and/or gaseous materials
Inventor: SCHOENFELD ROBERT
IPC: G05D7/01
Filed: 1981-12-18
Abstract: The invention relates to a hydrostatic or aerostatic bearing having a device which is connected in the bearing medium supply line to the respective bearing pocket for varying the medium flow as a function of the pressure difference between the input pressure and the output pressure corresponding to the pocket pressure, in the sense of increasing the flow rate when the pressure difference becomes smaller, i.e. when the pocket pressure increases. A housing chamber which is bounded by an elastic membrane is connected on the one hand to the medium input and on the other hand to the medium output and, in between, contains a variable flow resistance which is formed by a central region of the membrane and of the mouth of a housing opening located opposite the membrane. The bending of the membrane determines the magnitude of the flow resistance. The housing opening, whose mouth is a component of the variable resistance, forms the medium output. Arranged on the input side of the housing chamber is a bias resistance, which is fixed or adjustable from the outside, and reduces the input pressure, in front of which the medium input is connected to the membrane side opposite the medium output, so that the central membrane region is subjected to the input pressure on the one side and to the output pressure on the other side, and the outer region of the membrane surrounding the central membrane region is subjected to the input pressure on the one side and to the reduced input pressure on the other side.

Title: Electronically controlled fuel injection device
Inventor: KAMIFUJI HIROSHI
IPC: F02M71/00
Filed: 1982-01-11
Abstract: An electronically controlled fuel injection device contains a solenoid-operated fuel injection valve in an inlet duct, which is connected upstream to the intake pipe of an internal combustion engine, and a pressure governor, which controls the pressure of the fuel delivered to the fuel injection valve. The fuel injection device also has an enrichment jet, which opens into a Venturi section formed in the inlet duct and is connected to a return line, through which the excess fuel delivered by the fuel pressure governor is led back to a fuel tank. In the fuel duct leading to the enrichment jet is a valve element which opens the fuel duct when the air flow in the inlet duct is increased beyond a given level. As a result, during high-speed and heavy load operation of the internal combustion engine the fuel is also delivered through the enrichment jet to the inlet duct. <IMAGE>
