摘要:
The retractable rotary knob (1) for controlling power on a domestic stove, normally recessed in the stove control panel and projected for switching operations, comprises a marker ring (2) indicating the setting numbers (3) of the control knob (1), made of semi-rigid plastic in form of a strip, which clamps a peripheral body (6) of the knob The setting numbers (3) visible from above are impressed on said ring (2) which is fitted on said body (6) between two emerging ridges (13,14) by means of two retaining hooks to engage into corresponding openings on the body (6) wall. The marker ring has a gap in its perimeter for its diametral expansion. Interchangeability is facilitated by two enlarged ends which are pressed to release the ring from the knob.

The coupling (1) comprises a flexible run-off hose (2) whose end (5) is of larger diameter than the hose remainder tube (13), an outlet pipe (3) from a drain pump into whose bore said hose end (5) fits telescopically, and a swivel non-return valve (4) in the shape of a disc. The wall of the hose end (5) extends superficially in the opposite direction to form an elastic cylindrical skirt which fits over the rigid outlet pipe (3), covering it to from a watertight seal, and secure by an annular ridge (7) which fits into an annular groove of the outlet pipe (3). Coupling time is saved, no tightening accessories or tools are required and the non-return valve is of simplified design.

The interface circuit [1] gives the user two-way communication with electric appliances [APP1, APP2,APPn] connected to a data bus [S,N] for integrally managing a household kitchen via the telephone line. Around a main controller [2], it comprises signal detector [6] that is inter-connected with telephone tone detector/ generator [3], and voice and tone signals recorder/ reproducer (4), in addition to having variable user message memories [5] belonging to the recorder (4), and various external memories holding fixed response data addressed by the controller using a decoding process, and a FSK modem [11] for coupling said data bus [S,N] to interface circuit [1].
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.

The system incorporates advantages that comprise providing the positioning ratchet (23) with a shaft (25) about which an elevating lever (12) can swing which can take up an active and an inactive position such that when the cogs (10) on the block of program cams (15) elevate the ratchet (23), the elevating lever (12) takes up the active position and is thereupon returned to its inactive position when its free end (32) is moved by a rotatory boss (31) integral with the excentric cam (1), dragging with it in this latter movement the anti-return ratchet (15), causing the latter to draw away from the holding cogs (34) on the timer cam (6) at a time when the catch (4) on the driving pawl (3) is also drawn away from the same, allowing the timer cam to be reset.
摘要:
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 regulator device makes a dynamic regulation of the water, operating when the spray and the dishwasher impeller pump are running, and it comprises a float (3) inside a flotation chamber (4) connected to the dishwasher tub, a lever (8) which pivots on an end shaft (8a), an electric microswitch (6) which is operated by said lever (8) when the float (3) rises, a mechanism (9, 10) which pushes said lever (8) to snap switch two stable positions of said lever (8) in relation to the microswitch (6), and a support plate (12) for the regulator device (1). The rod (3a) of the float does not affect the lever (8) in a prior run between two water levels (2, 2b).

The emergency system for stopping vehicles consists in strategically providing a press-button which, in a case of emergency, may be actuated thereby causing the operation of an electric motor (3) and a hydraulic pump (4) which are part of the normal braking circuit (13), so that the complete stopping of the vehicle is achieved without having to step on the conventional brake pedal, either when the driver has a physical or mental problem or when a failure occurs in the normal braking circuit (13).
摘要:
The system, having the usual blocks of fast cams and program cams (6), activated step by step by means of a pawl (3) which is provided with a steady to-and-fro motion by an eccentric cam (2), incorporates a swinging detent (9) that can take up two positions, one standing in the way of the free end (7) of the actuation pawl (3), and a likewise swinging clearance lever (13) with three working positions, the detent (9) being inactive in two positions and active in the third. This first part of the system is assisted by a selector lever, a timer lever and an anti-return ratchet, the said subsystem allowing the length of the timings deriving from the previous subsystem to be multiplied, thereby considerably enhancing the practical possibilities of the timer switch.
