Patent EP-0267988-A1 (EP)
Inventor: STEELE BRUCE BUTTON
IPC: G03G15/09
Filed: 1986-11-20
Abstract: A magnetic brush applicator (12) for use in an electrographic reproduction apparatus for applying a magnetic developer (D) to a recording element comprises a cylindrical non-magnetic sleeve (20) having a rotatably driven magnetic core piece (22) positioned therein. According to the invention, the axis (Aʹ) of rotation of the magnetic core piece is displaced from the sleeve axis (A), such displacement being toward a development zone at which the applicator applie                s developer to the recording element, and preferably toward region of such zone at which the recording element exits therefrom. As a result of the non-concentric arrangement between the applicator's sleeve and core piece, the torque requirements for rotating the core pieces are reduced, developer replenishment is facilitated, less thermal energy is introduced into the developer during rotation of the core piece, and magnetic carrier pick-up by the recording element is reduced.

Abstract: 1. Commutator for the combined control of the direction indicator lights and parking lights of an automobile by means of a movable arm (10) which pivots in one or the other direction with respect to a fixed housing (20) from a central neutral position (A) to a first, stable position (C), then a second, unstable position (D), passing through the first position, these positions being such that : - the passage from the neutral position to the first position causes the direction indicator lights to change from the neutral state to the operational state, - the passage from the first to the second position also causes the setting of a bistable member, rest by the return to the neutral position, the set state of the bistable member corresponding to an inoperational state of the direction indicator lights and an operational state of the parking lights, after opening of the vehicle lighting contact circuit, the said commutator comprising : - two direction indicator light contacts (40) which are selectively closed by one end of the pivoting arm cooperating with the respective contact when the arm is located in the first position, - two parking light contacts (200) which are selectively closed by the setting of the bistable member, the said commutator being characterised in that : - the parking light contacts (200) each include a fixed stud (210) for the current supply and a fixed contact stud (220) connected by a contact bar (100) which is movable with the pivoting arm (10), - this bar (100) is flexibly connected to the arm (10) and mounted so as to be floating in such a way as to provide a clearance in translation (b) parallel to the plane of the studs and a clearance in tilting (c) about the axis of the arm, this bar having two lateral extensions in the form of fins (140), - and for each direction of displacement a rocker (300) is provided which is flexibly connected to the housing and includes a ramp (330) cooperating with the corresponding fin of the bar in such a way that : - during the transition from the neutral position (A) to the first position (C) the fin comes to rest on the upper face (331) of the ramp, raising and tilting the bar so as to distance it from the corresponding contact stud, - during the transition from this first position (C) to the second position (D), the fin having reached the top (333) of the ramp ceases contact with the rocker, releasing the bar in such a way that the latter goes down again and rights itself in order to come into contact with the contact stud and the corresponding current supply stud, - during the transition from this second position (D) to the first position (C) the fin comes to rest below the lower face (332) of the ramp, raising the rocker, in such a way that the flexible connection (400) between the rocker and the housing comes to press the bar against the studs.

Abstract: A bellows seal apparatus for use in compressors or the like which has a pump (15 and 115) arranged and controlled to maintain a desired pressure differential between the inside and a driving mechanism (18, 130 and 230) having a connection with a movable end (113) of the bellows and an additional connection or connections with said bellows at unequally spaced points inermediate to the ends of the bellows to provide the least maximum stress levels in the bellows convolutions of each and thus the maximum life expectancy for the seal. The driving mechanism may take many forms but is so designed that it will elongate and contract each section of the bellows a distance depending upon the dynamically caused stresses in each section and the composition of and the number of bellows convolutions in each section.

Abstract: A print head for a printer is constructed as an optical character generator and comprises a plurality of switch cells arranged in a two-dimensional field. The energy output by radiation source is transmitted in parallel onto the matrix dots arranged in a grid and these matrix dots lie in the plane of an ink layer on a band-shaped continuous carrier. Each of the switch cells comprises an optical switch element composed of a transparent ferro-electric ceramic substrate composed of lead, zirconate titanate doped with lanthanum and having transparent electrodes for applying a pulse-shaped controlled voltage. In response to a corresponding control voltage, the radiant energy is transmitted frm the switch element into the allocated matrix dot, for example, for a local melting of the ink layer on the carrier, which was coated with a thermo plastic printing ink having a low melting point. The printing arrangement is suitable for line printers having single colors or multiple color printing.

Abstract: A breathing mask (1) is described which contains an exhalation valve (18) arranged in an aperture (6) in the wall (2) of the breathing mask (1). The exhalation valve (18) possesses a thin diaphragm (23) which can be moved towards and away from a sealing seat (28) by the pressure of breath during inhalation and exhalation. In order to produce a reasonably priced breathing mask whose exhalation valve closes reliably, particularly when the air contains dust particles, and which nevertheless has low opening and closing pressure, the diaphragm (23) is provided with a convexity (24). The air can then escape only over part of the circumference of the diaphragm, while the remaining part of the circumference (22) of the diaphragm (23) is connected to a base part (27) in such a manner that the direction of convexity of the convexity (24) is at least partially reversible by the pressure of breath. <IMAGE>

Dans chaque voie, un transistor (6,7) est monté en système oscillant, et son énergie est recueillie sur une de ses électrodes d'accès, le drain. Les deux transistors sont montés de façon que leurs courants de sortie soient en opposition de phase, ce qui diminue le bruit FM autour de la porteuse. Selon l'invention, l'opposition de phase est obtenue au moyen d'un varactor (14) connecté entre les grilles des deux transistors (6,7). Le varactor (14) est découplé en courant continu au moyen de deux capacités (15,16). Pour augmenter la plage de fréquences, deux autres varactors (24, 25) peuvent être montés de façon analogue sur les circuits de source des deux transistors (6,7).
