Title: Composite metal sheet cooking utensil and  manufacturing method
Inventor: EIDE SVEIN
IPC: A47J36/02
Filed: 1979-10-01
Granted: 1982-05-18
Abstract: Abstract of the Disclosure A composite metal sheet cooking utensil (laminated cooking utensil, cooking pot, frying pan) built up of a core of a metal having relatively good heat conductivity such as alumi-num, copper, common quality steel etc., coated on one or both sides with a relatively thin layer of a more corrosion resist-ive metallic material such as stainless steel, titanium etc.          The lamination layers (sheets) are bonded to one another across the bottom surface of the cooking utensil and some distance upwardly the lower portion of the cooking utensil wall.         A laminated circular blank for the cooking utensil comprises two or more flat round metal sheets provided with soldering agent and possibly flux agent on their central con-tact surfaces facing one another and corresponding to the area of the cooking utensil bottom and a part of the lower portion of the wall.         The cooking utensil is manufactured (shaped) by deep drawing and the sheets can be soldered (brazed) together before or after deep drawing to provide a lamination.

Abstract: ABSTRACT OF THE DISCLOSURE     A monitoring device for monitoring the operation of a vehicle internal combustion engine having inlet ducting for admitting a fuel/air mixture into the engine comprises vacuum sensitive means for sensing the degree of vacuum in the inlet ducting, speed sensitive means for sensing the rotational speed of the engine, and warning means including gates, multivibrator circuitry, a loudspeaker, and a recorder.          When the degree of vacuum falls below a predetermined vacuum value, warning bleeps are issued by the loudspeaker and recordings are made on the recorder.  The warning means is operative in response to the vacuum sensitive means and the speed sensitive means to provide a predetermined vacuum value which is a stepwise increasing function of rotational speed sensed.     An inclined mercury containing capsule is provided to inhibit bleeping and recording when the vehicle is inclined at more than a predetermined angle to the horizontal in the direction of travel of the vehicle.

Abstract: DIGITAL CARDIAC PACEMAKER            ABSTRACT           There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of cardiac stimulating pulses. The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sen-sitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the reed switch overridden, a hysteresis function added and a high rate ex-ceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the accept-ance of a programming signal, and means to reset the program acceptance circuit if extraneous signals are detected as pro-gramming signals.  The program signal acceptance circuit per-forms several different checks on the detected programming signal including a parity check, an access code check and de-termining if the proper number of signals were transmitted within a given time.  The timing circuit of the pulse genera-tor includes a crystal clock oscillator and counter means for counting theclock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.

Abstract: Abstract A laser echo ranging device (lidar) is used both to measure cloud height and to measure slant range visibility.  The distance for which the echo falls to the noise level is measured by a counter, and the echo voltage for a distance selected by a time switch for example for chosen distances in 100 meter steps is also stored.  These values are measured for various angles of elevation and can be used to compute the slant visual range.  Reference to the data for the different angles of elevation yields the layer structure of inhomogeneous scatter-ing characteristics of the atmosphere.

Abstract: MEMORY WRITE ERROR DETECTION CIRCUIT      Abstract of the Disclosure A circuit for the detection of write errors in a memory with selectable byte addressing.  The memory is capable of selectively writing bytes within a memory word by decoding control signals and address signals received from a processor.  A decoder and a transmission path of the control signals are checked by the processor generating incorrect parity for the bytes which are not to be written. The memory decodes the control signals. checks the parity of the bytes, and generates a write parity error if the decoder selects a byte with incorrect parity to be written If the memory malfunctions and spuriously writes an unselected byte, this fact will be detected when the unselected byte is read.  The memory checks each byte read for parity, and incorrect parity causes the memory to transmit a read memory error to the processor.

Abstract: ABSTRACT     Oily mill scale recovered from steel manufacturing operations downstream of a refining stage for molten steel is recycled to the refining stage.  Coarse particles of mill scale are removed in a pre-screening operation, the mill scale is mixed and blended with a binder, and the mixture is agglomerated into shapes, such as briquettes, using exter-nal mechanical pressure.  The agglomerated shapes are intro-duced into molten metal containing excessive carbon, where the shapes act as a coolant and the iron oxide in the mill scale reacts with some of the carbon.  The oily mill scale is neither deoiled nor ground more finely prior to intro-duction into the molten metal, and all processing of the mill scale is conducted under ambient conditions of temper-ature, pressure and atmosphere.  The agglomerated shapes may be aged prior to introduction into the molten metal.

Abstract: ABSTRACT OF THE DISCLOSURE           An airflow sensor with a rectangularly shaped sensing vane is disclosed.  The vane is pivotally mounted in a cylindrical  bore perpendicular  to  the airflow direction of the  sensor  and yields an airflow signal proportional  to  its  angular  rotation.   An  air  motor mechanically coupled  to the vane maintains a constant pressure drop across the vane.  The air motor assists in pivoting the vane by magnifying the force on the vane for changes in airflow.   In one embodiment,  a gas filled bellows modifies the positioning of the vane by the air motor  to  compensate  for  temperature  and  barometric variations.  In another embodiment, an absolute pressure sensor, located between the vane and a throttling member, compensates for barometric changes and transient delays in the response of the vane.

The magnitude of the fluid pressure communicated to the pressure chamber (14) is a function of the balance of spring forces applied to the control valve (42) by a pair of opposed springs (50, 82). An adjustable assembly (92) engages one of the opposed springs (50, 82) so that the balance of spring forces applied to the control valve (42) may be adjusted to limit to a safe level the maximum fluid pressure communicable to the pressure chamber (14).
