The driving gear commutator switch incorporates a driving lever (1) with two tappets (10,13) located on either side thereof and at different distances with regard to the rotational axis (2). It also includes a conductor strap (6), which may be arranged in either of two opposite orientations, with regards to the fixed contacts (14). The strap is provided with at least one side projection and sidely arranged spaces or gaps allowing free passage of the tappets.

PH controller where phase controlling takes place relying upon a micro-controller. Speed selection is by means of external switches governed by the system of contacts of an electromechanical programmer. The micro-controller has a program in charge of measuring motor speed. This measure is taken from the signal delivered by a tachymetric pick-up (tachogenerator). It also contains a control algorithm deciding, from the speed error obtained, the tripping angle from the passage through network zero to drive a power element (triac) to energise the washing machine motor.

The support for the food tray (2) in a baking oven, comprises a pair of immobile lateral supports (4) made of wire rods, and a horizontal sliding grill (3) on which the tray rests, being supported and guided between two rod guides (7) of the lateral supports, and conformed by a pair of parallel wire rods (7a,7b), which are arranged a short distance apart from each other, but forming a broad entrance mouth. The grill (3) has retention means (3a) to be retained against a stop in a guide (7b) of the lateral supports, after a partial displacement, and means (8) for centring the tray (2), being all of them integral and also made of wire rods.
摘要:
The pressure cooker (1) is intended for household cooking, and performes cooking processes at any one of three pressure ranges, i.e. high, medium and low pressure, if the vessel (2) is fitted with its lid (7), and also frying and grilling processes with no lid, them being selected from the control panel (10) which indicates whether the cooking pressure is normal or abnormal. Heater stand (3), which is adapted to take the cooking vessel (2), embodies two temperature sensors (22, 23). The attachment between the heater stand and the cooking vessel is accomplished by an integral upright column (11) which guides a travelling member (4) carrying a lid detector, the temperature sensor (22), and ducts (12) for conveying the released steam.
摘要:
Such uses the profile interpolation technique determined from two points P₁, P₂ obtained by sampling the spatial X, Z and angular S position of the tool tip, points P a , P b making up two upper (A) and lower (B) profiles, and superposing at such points P a , P b the profile of the part (MP) and of the tool (MC) to provide real information of the contour obtained in the machining process. The system is independent of the kind of graphic display used, and can be incorporated to numerical controls provided to a display screen or conveniently to computer aided design (CAD) systems to aid programming at a stage prior to actual machining.
摘要:
One of the improvements comprises providing two ducts (16-17/21-22) communicating the drum whose water level is to be controlled and the pressure chamber (4) in the pressurestat, the said ducts having respective nozzles or restrictors (18/23) in order to minimise the risk of the intercommunication between the pressure chamber (4) and the washing drum from being blocked. The second improvement, namely preventing the operation of the machine in the event of a given default, comprises providing a safety pressurestat in which the release spring (14) opposed by the membrane (3) is scaled such that its tension is not enough to reset the pressurestat when the latter is triggered due to abnormal excessive pressure in its chamber (4) caused by the said breakdown, which release spring (14) is supported by a push-button (24) which must be manually pressed in order for the machine to recover the operating position, which will only be done by the servicing expert once the fault is put right.
摘要:
The system provides for oven control allowing the carrying out, both manually and by selecting preset recipes, of the different stages involved in cooking. Interactive selection allows programming thereof to carry out recipes automatically once the same is selected or activating the various types of oven according to the user's selection. To such end, the system is provided with two functionally linked cards, a MASTER card (1) dealing with system control and a SLAVE card (2) basically aimed to try and represent the information on a CRT display (28) interacting with the former. Especially to be noted within the power supply (3) is the presence of a mains fault detector circuit (38) and a mains-battery/battery-mains switching circuit (39), so that the structure and processes that can be carried out allow oven control and interaction with the user through a selection keyboard 912) and the CRT display (28).
