Title: Method of producing electrical heating elements and electrical heating elements so produced
Inventor: BOARDMAN JEFFREY
IPC: H05B3/16
Filed: 1988-06-27
Abstract: A method of forming an electrical heating element in the form of an electrically non-conductive supporting body onto which an electrically resistive material is deposited, the method comprising the steps of preparing a dry metal powder of irregularly shaped metal particles of widely varying sizes, in the range 20-150 microns, roughening the surface of a supporting body onto which a heating element is to be formed, pre-heating said surface of the supporting body to a temperature within the range of 150-250 DEG C and flame spraying the dry metal powder onto said heated surface of the supporting body in a plurality of passes over the supporting body. The effective resistivity of the flame sprayed deposit is predetermined by adjusting the amount of oxidation on the surfaces of the metallic particles sprayed onto the supporting body. The amount of oxidation on the surfaces of the flame sprayed particles, and hence the resistivity of the sprayed deposit, can be varied by selecting the size range of the particles used, within said range of 20-150 microns. Alternatively the amount of oxidation on the surfaces of the flame sprayed particles can be varied by blending selected alloys into the powder to by sprayed such as to adjust the quantity of conductive oxides present on the sprayed particles.

Title: Temperature compensated exponential gain control circuit
Inventor: FRITZ SCOTT N
IPC: H03G1/04
Filed: 1990-02-28
Abstract: The invention is directed to apparatus for providing temperature compensated exponential gain voltage to an AGC amplifier using emitter coupled pairs of transistors to implement an exponential gain control function. The invention adds additional circuitry to drive the bases of the transistor pairs. The additional circuitry adds one gain stage in which the bias current is proportional to temperature and a second gain stage with a bias current which is constant over temperature. These gain stages, in combination with the transistor pairs, have no temperature dependence and retain the exponential gain function. This allows a user to set the gain of the amplifier by an external voltage source providing a gain which is temperature independent. An advantage is the cancellation of temperature dependence without the use of any temperature sensitive components. …<IMAGE>…

Title: Fluids heaters such as boilers
Inventor: FRIEDRICHS DETLEF
IPC: F23M9/10
Filed: 1990-05-21
Abstract: Means for heating a fluid such as water comprises a burner (4) and at least two heat-exchange units (12 and 11) arranged one after the other in the direction of flow of the combustion fuel. The first heat-exchange unit (12), which is disposed nearest to the burner (4) downstream of the fuel outlet opening and immediately in a flame region, withdraws heat from the flame region, the flow rate of heat thus withdrawn amounting to between 5 and 50% of the total heat flow.

Title: Disk driving apparatus
Inventor: ONOOKA YASUSHI
IPC: G11B21/22
Filed: 1990-10-08
Abstract: A disk driving apparatus having a retract mechanism for a read and/or write head 3, is provided with a cam 7 which bends a spring 5 supporting the read and/or write head to bring the read and/or write head out of contact with the recording disk 1 and to cause the head 3 to land on a landing plate (8) (see Fig 5) after being retracted. The landing plate may have a surface 11 which protects and/or cleans the head. Thus the read and/or write head and the spring are supported such that, even in the case in which stress from the exterior is added, the stress is not added to the connecting part of the read and/or write head 3 or the spring 5, making the read and/or write head hard to destroy. Several examples of materials suitable for the surface of the landing plate are disclosed, eg: non-woven fabric or brushlike material. <IMAGE>
