Title: Device for the operation of an auxiliary electric switch in conjunction with other apparatus
IPC: H01H3/02
Filed: 1931-11-20
Abstract: 397,464. Controllers with auxiliary switches. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI, 91, Rue de l'Enseignement, Brussels. Nov. 20, 1931, No. 32221. Convention date, Nov. 25, 1930. Void [Published under Sect. 91 of the Acts]. [Class 38 (iii).] For operating an auxiliary switch before rotary movement is imparted to a piece of apparatus, e.g. a motor controller, a screw and nut mechanism is interposed between the driving means for the controller and the controller itself, one member of the screw and nut mechanism having a limited axial movement during which it operates the auxiliary switch, and at the end of which the screw and nut become locked together to transmit motion from the driving means to the controller. A handle 1 is fixed to a barrel 2 which has longitudinal ribs 2<1> engaged by longitudinal grooves in a screw 3. The screw 3 has helical square threads, engaged by the threads of a nut 6 fixed to the controller shaft 19, and radial pins 4, passing through helical slots in the nut 6, provided at their ends with rollers 5 which are caged in a lantern 7 free to slide on the outside of the nut. Thus when the handle 1 is rotated, the screw 3 is first raised, and with it the lantern 5. The lantern 5 has diametrically opposite pins on its outside which engage elongated slots in a pair of arms 9 attached to a spindle 10 mounted in brackets 11, so that when the lantern is raised, an arm 12 also attached to the spindle 10 is rotated, and by means of a contact 14 which it carries at its end, bridges fixed contacts 16. The auxiliary switch is thus closed, and the screw 3 reaches the end of its axial travel, and the screw and nut are locked together, so that further rotation of the handle rotates the controller 20. In a modified construction the barrel 2 is replaced by a screw, and the screw 3 by a movable nut, longitudinal ribs being provided on the outer surface of this nut, which engage with longitudinal grooves in a member fast with the shaft 19. This latter member has holes for the passage of radial pins, and the movable nut is caused to abut against upper and lower stops carried, for example, by the screw attached to the handle. The auxiliary switch may be in the energizing circuit of the main electromagnetic or electropneumatic contactor of the circuit controlled by the controller 20. Alternatively, the auxiliary switch may be used to shunt the series field of a compound wound motor during regenerative braking. In a further application the switch may excite an electric, electrohydraulic, or electro-pneumatic brake on a vehicle or hoist, and in yet another application the switch may close a circuit to give a warning at a distance that a certain operation is about to be effected.

Abstract: 537,382. Delivering thread etc.; clutches. INDUSTRIAL RAYON CORPORATION. Dec. 18, 1939, No. 32458. Convention date, Dec. 27, 1938. [Class 120 (ii)] [Also in Group XXIV] A reel for winding and delivering thread &c. is connected to its supporting means by a device which permits restrained relative rotation between the reel and the supporting means so long as a predetermined torque difference is maintained between them ; slipping between the reel and its driving means is permitted when the predetermined torque difference occurs. As shown the reel comprises sets of bars 35, 36, Fig. 3, carried by members 33, 34 which are mounted on inclined axes disposed in parallel planes so that the turns of the thread on the reel are alternately engaged by the two sets of bars and progressively moved from the supported to the unsupported end of the reel from which the thread is delivered to another reel disposed beneath it. The member 33 is carried by the driving shaft 17 and drives the member 34 which is carried by a flanged member 53 mounted on ball bearings on a supporting member 54 by which the reel is removably secured in the frame of the machine. A diametral bore in the shaft 17, Fig. 7, houses a spring 79 engaging a pair of balls 77 which when driving engage apertures 76 in an hexagonal block 72 secured in the bore of the member 33. When the torque exceeds a predetermined amount the balls are forced into the bore in the shaft and slip occurs between the member 33 and 'the shaft; the block 72 is secured in the member 33 by a snap ring disposed between an inner inclined wall of a circular recess in the member 33 and flats on the corners of the block. In a modification the member 33 is fixed to the shaft 17 and the driving gear 16 is connected to the shaft by a similar clutch disposed in the gear, the balls of the clutch engaging recesses in the flanged ends of a sleeve fixed to the shaft or the gear driving the gear 16 may be similarly connected to the shaft 14 driving the reels of the unit. In another form a collar 98, Fig. 12, fixed to the shaft 17 carries a number of flexible fingers 97 engaging grooves or notches 101 in a block 102 fixed in the reel member 33, the fingers may be carried by the reel member and the grooved or recessed block by the shaft. Specifications 413,414 and 474,973 are referred to.

Filed: 1963-08-16
Abstract: 1,062,473. Wave-energy position finding. ALBISWERK ZURICH A.G. Aug. 16, 1963 [Aug. 30, 1962], No. 32498/63. Heading H4D. [Also in Division F3] In a system comprising tracking means obtaining position-data relating to bodies F and Z and wherein the motion of body F is controlled so as to reduce control signals formed by comparing such data, the control unit incorporates delay of the position-data relating to F and/or Z and generates control signals representative of the rate of change of the difference between angular components of F and Z position-data. The system may be such that the Z position-data is supplemented by programmed data such that F may be controlled in anticipation of Z's movements. Body F may be real or be simulated by a sight on a gun barrel. The system may bring about or prevent collision between F and Z. In one embodiment (Figs 2 and 3) F and Z are a guided missile and a target respectively, both are tracked by known radars to yield respective range r, azimuth α and elevation # data rF, αF, #F and rZ, αZ, #Z; the Z data passes through an optional delay unit (S2) and that relating to F through a delay unit (S1 yielding output signals rF<SP>*</SP>, αF<SP>*</SP>, #F<SP>*</SP> (* signifying delay). The quotient rZ/rF<SP>*</SP> is formed by a divider (RD) in a delay control circuit (SR) which incorporates a temporal differentiator (D1) following the divider and the output of the differentiator controls the delay in unit S1. A command signal circuit (KS) forms quantities #α=αF<SP>*</SP>#αZ and ##=#F<SP>*</SP>##Z, these quantities being differentiated temporally before transmission to the guided missile which is caused thereby to collide with the target. For anti-collision, constant magnitudes are added to the signals d(#α)/dt and d(##)/dt before transmission or a pre-set delay (V) may precede delay unit S1 In another embodiment (Fig. 4) body F is an infra-red emitter attached to a gun barrel (whose azimuth and elevation are controlled by the command signals) and tracked by a known device; the delay (V, Fig. 3) then provides for lead synchronism. The emitter is located to allow for the ballistic course of the gun's projectile. The delay units may be of the magnetic drum type (Fig. 5). The delay control circuit (SR of Fig. 3) is described (Fig. 6); division is by variation of the negative feedback by the signal rF<SP>*</SP> of an amplifier fed with the signal rZ.
