Abstract: ABSTRACT     An automatic electric cigar lighter, and especially a cigar lighter igniting unit as used for automobiles and the like.  The cigar lighter has a holder which presents an out-wardly facing socket, and embraces a unique ignitor plug that is received and stored in the socket. At its inner end the plug has a heating element for electrical connection in the circuit of a heat-responsive switch which is also carried by the plug.  The latter comprises a manually operable part by which the heat-responsive switch can be closed to complete the heating circuit through the element.  A bimetallic member is also carried by the plug, being engageable with one of the switch parts and normally  having a circuit-opening position wherein it maintains the one switch part separated from the other.  The member is shifted to a closed-circuit position when the plug is actuated.  In both positions it receives radiant heat when the heating element is incandescent.  In its closed-circuit position it can carry the heating current, and will snap to the circuit-opening position to effect break-ing of the lighter circuit and de-energization of the heating element after useful incandescence of the element has been reached.  Central portions of the bimetallic member are free and not attached, being instead merely disposed in close prox-imity to one of the switch parts, such that the member can quickly effect opening of the switch without need for mecha-nical securement of its central portions.  A special spring-biasing mounting arrangement is provided for the bimetallic member, resulting in high conductivity through the heating element circuit without imposing undue mechanical restraint on the member.  The advantage of this construction over the devices of the prior art is that a more reliable operation is had, with greater freedom from malfunction and premature failure.

Abstract: CURRENT CONTROLLED DISK REPLICATOR                          Abstract A magnetic bubble domain chip having two levels of metallurgy fabricated in a single masking step and including a replicate type bubble generator.  The bubble generator includes a magnetic disk which holds a seed domain during reorientation of a magnetic drive field in the plane of the magnetic bubble material, and a conductor located at the leading, i.e., cutting, edge of the magnetic disk.  Current in the conductor is used to assist the splitting operation whereby a new domain is split from the stretched seed domain.  The conductor includes a first portion having a relatively wide cross-section where most of the current flows through a highly conductive material, such as gold.  In the area of the generator, the conductor is narrow and the current path is through the magnetic material comprising the disk.  Use of the magnetic material as a conduc-tor path reduces problems due to electromigration and the generator is particularly suitable for use in providing magnetic bubble domains having diameters 2 microns and less.

Abstract: ENERGY CONVERSION METHOD AND SYSTEM     ABSTRACT         A mechanical energy conversion method and system for the restoration of dissipated heat energy, contained in natural or artificial water bodies at or near ambient temperatures, to industrial process heat, mainly in the form of steam up to 200°-400°C.  The sensible heat contained in a water body is concentrated as latent heat in low pressure water vapor which is thermo-compressed by steam ejection to an intermediate pressure level, wherefrom mechanical compression takes over, generating highly superheated output steam.  The ejecting steam is not generated in a boiler, but is continuously regenerated by the compressor and routed back for repeated ejection.  The compressor is driven by a heat engine whose reject heat is collected and upgraded as well.  The output of heat energy is essentially equal to the sum of the heating value of the fuel consumed and the intake of latent heat and amounts thus to substantially more than the heating value of the fuel alone.  In cases where an aqueous feed medium is available at temperatures ranging from warm to hot, water vapor generated from the medium in initial evaporation stages may be delivered directly to a mechanical compressor without thermo-compression.  Steam ejection may be dispensed with entirely if below-tepid temperature cooling capacity is not required from the system.

Abstract: ABSTRACT      The invention provides a control system which predicts the brake re-apply point during a brake pressure release/re-apply cycle by measuring the duration of the synchronous running period, that period during which the wheel is decelerating at substantially the same rate as the vehicle.  An increase in the synchronous running period above an optimum period is arranged to bring about an earlier re-application of the brakes in a cycle, and a decrease in the synchronous running period is used to effect a later re-application of the brakes. Various circuits are disclosed for detecting the duration of the synchronous running period.  In a preferred circuit a track and store circuit compares an acceleration/ deceleration signal with a stored signal whose amplitude follows that of the acceleration/ deceleration signal, and the synchronous running period is taken to be the period between coincidences between the acceleration/ deceleration signal and the stored signal.  The timing of the brake re-apply signal is preferably controlled by varying a re-set threshold of a threshold switch responsive to wheel acceleration/ deceleration.

However, the other filter elements may also have a similar effect.  Consequently, the operation of the oscillator is critically dependent on the positions of the filter elements: adjustment for optimum operation is lengthy and difficult, and results are not reproducible.  To mitigate these disadvantages, the invention provides a Trapatt oscillator which does not require a low-pass filter: there is a single trigger element (S) and a progressive increase in impedance from the Trapatt diode (T) to the trigger element (S).
