Title: Energy generating appts. using differences in densities of fluids - can utilise geo-thermal and other natural sources of heat
IPC: F03G7/00
Filed: 1976-03-04
Abstract: The apparatus for generating energy has two vertical tubes (10, 20) with thermally insulated walls (11, 21). The tubes are connected at their lowest ends through a heat exchanger (15). The upper ends are joined through a turbine (25) and a radiator (30). Heat supplied by the exchanger (15) causes the fluid in the tube (20) to expand with consequent reduction in density so that the fluid rises. It flows through the turbine (25) generating power and then gives up heat in the radiator (30). The cold dense fluid then descends in the tube (10) to complete the cycle. Heat from geo-thermal or other natural sources may be used to drive the machine.

IPC: G01N27/22
Filed: 1977-01-19
Abstract: Appts. registers the degree of foam in the suds of a washing machine fluid or emulsion flow stream. A portion of the flow forms the dielectric of a condenser, the capacity being compared with a reference condenser. An initial induction coil is formed by a double lead winding round a ferrite core. Both components of the twin leads are connected in series, the connection between them being the central tapping of the coil. A condenser forms a parallel resonance circuit lying over the initial coil. Both ends of the initial coil are connected to a present capacitance and an electrode forming a capacitative component, contg. the dielectric form the following medium or emulsion. The central tapping is connected to the output of an amplifier whose input is provided by a second induction coil formed by a separate winding round the core located approximately in the centre between the ends of the twin lead winding and inductively connected to the initial coil. The opposing induction between the initial coil and the detection coil forms a feedback loop for the amplifier and the control circuit, the oscillation of the amplifier generating an output signal. The design gives a simple circuitry which gives a positive reading of the foaming density.

Title: Electronic programming device for washing machine - comprises two=part system for cooperating with pick=ups in machine etc.
Inventor: MONIE JEAN
IPC: G05B19/12
Filed: 1977-01-21
Abstract: A programming device comprises two distinct parts: a first part with a low tension feed provided to co-operate with pick-ups disposed on a machine, and a second part constituting interfaces comprising power contacts intended to be relayed to the elements of the machine. Means are provided to select a required programme from aming serveral pre-established programmes in the programming device, and also to set up the selected programme. Known electronic programmers require special equipment to put the programming into action, and it is difficult to modify the programme at a later stage, since it is necessary to re-programme the memories of the integrated circuits. Should a cut-off occur suddenly, information regarding the programme selected up to this point is lost. It is difficult to re-start in the middle of a sequence, or to intervene manually in the running of the machine. The programming device of the invention avoids such difficulties but at the same time maintains certain inherent advantages of known programming devices. The programming device may be used to control the cycles of a washing machine, or a washing-up machine.
