Abstract: 1,039,100. Protective systems. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. May 13, 1963, No. 18881/63. Heading H2K. [Also in Division G1] An arrangement for indicating failure of one or more rectifiers or groups of rectifiers of a number of rectifiers mounted on the rotor of an electrical machine, comprises an optical or magnetic fault responsive device associated with each rectifier or group of rectifiers, arranged along one or more circumferential paths around the rotor, and effective to operate a fixed sensing arrangement which indicates rectifier failure. Fig. 1 shows the fault-responsive device associated with each rectifier 1, the device comprising a glow lamp 4, capacitor 3, auxiliary rectifiers 2, 6, resistor 7 and a fuse 8. The glow lamp 4 is normally lit, but should a shortcircuit occur in the rectifier 1, the lamp 4 is short-circuited and extinguished. Alternatively, should the rectifier 1 become open-circuited, the resulting increased current through the rectifier 6 and resistor 7 blows the fuse 8 to extinguish the lamp. In Fig. 3 (not shown), five of the lamps associated with five of six rectifiers or groups of rectifiers are arranged in a first circumferential path and the sixth is arranged in a second path, a fixed photo-sensitive device being associated with each path. The pulses provided by the photo-sensitive device associated with the first path are supplied to a pulse counter which is reset each revolution of the machine by a pulse from the photo-sensitive device associated with the second path providing that five pulses have been registered by the counter. At each resetting of the counter a holding pulse is supplied to a relay so that should any lamp be extinguished the relay is released to provide an indication, Fig. 4 (not shown). The lamps may be replaced by coils of magnetic devices which co-operate with stationary induction coils to produce pulses, Fig. 2 (not shown).

Title: Writing instrument mechanism
IPC: B43K24/08
Filed: 1958-06-12
Abstract: 894,355. Reservoir pens. WPC ENTERPRISES Inc. June 12, 1958 [June 13, 1957], No. 18885/58. Class 146(3) A retractable ball-point pen comprises a reciprocable actuating plunger 18, a writing unit 48 biased rearwards by a spring 53, a continuous groove 45 on said plunger having axially spaced lock paces 55, 56, and a flexible latch arm 34 on the barrel having a portion 38 constantly disposed in said groove and engageable with one or other of the lock faces upon successive reciprocations of the plunger thereby holding the unit 48 and plunger 18 against rearward axial displacement by the spring 53 in either retracted or projected position. The arm 34 is secured at one end to a member 21 which is screwed into the barrel (not shown) by means of a screw-threaded portion 24. The member 21 has a bore 23 in which the unit 48 is slidable, and an arcuate extension 27 in which is guided a corresponding arcuate face of the plunger 18, the plunger being restrained against rotation relatively thereto. A spring 54 which is stronger than the spring 53 is interposed between the enlarged rear end 52 of the writing unit and the forward end of the plunger. The groove 45 is roughly heart-shaped (Fig. 9) and is formed in its base with ramps 61, 63, 68 inclining upwards in the direction of the arrows and terminating in ledges 62, 64, 69 respectively where the depth of the groove increases abruptly. When the end 38 of the arm 34 is engaged at the lock face 56 the writing unit is at projected position, a shoulder thereon abutting against a shoulder at the front end of the barrel. Axial pressure on the plunger compresses the spring 54 and the end 38 moves to the face 65 of the groove: when pressure is released the plunger and writing unit are carried back by the spring 53 unitl the end 38 comes to rest at lock face 55, in which position the writing point is. retracted within the barrel. A second depression of the plunger causes the end 38 to move anticlockwise round the groove and come to rest at the lock face 56 again. The ramps and ledges guide the end 38 in the groove and ensure that its movement in relation thereto is always anticlockwise.

Title: Improvements in and relating to remote-control switches for alternating currents
IPC: H01H9/56
Filed: 1937-07-07
Abstract: 496,415. Electromagnetic switches; arc-rupturing. BRITISH THOMSON-HOUSTON CO., Ltd. (Allgemeine Elektricitats- Ges.) July 7, 1937, No. 18930. [Class 38 (v)] In an electromagnetic remote-controlled switch having main contacts 23, 22 in series with auxiliary contacts 21, 20, the auxiliary contacts 21, 20 are the first to open and by so doing remove a short circuit from a blow-out coil 25a which magnetizes pole-plates 10 which attract an armature 31 thereby preventing contacts 23, 22 from opening till the current is at or near the zero of the A.C. cycle. In the form shown the voltage coil 3 normally attracts an armature 4 pivoted at 7. On de-energization of the coil 3, a spring 8 moves the armature 4 about its pivot and the end 4a pushes the contact spring 20 away from the fixed contact 21. A dead-centre spring 5 is also moved so as to press the contact spring 23 to the left but movement of the contact 23 is prevented as already stated till the current is near zero. The contacts 20, 23 are mounted on springs bent as shown, the electrodynamic forces tending to hold the contacts together. In a modification, Figs. 1-3 (not shown), the armature 4 acts only on the contact 23 and the two contact portions 22, 21 have connected between them an additional coil which on overload, by magnetization of the pole plates 10, attracts an additional armature, which is also pivoted at 7 and in its movement opens the contacts 20, 21 and also, through the medium of a link and dead-centre spring, opens contacts in series with the coil 3. The armature 4 is thus released and opens the contacts 23, 22 as before at the zero of the cycle. A bimetal release may also be provided, adapted to break in a similar way the circuit to the coil 3. The invention is shown applied to a three-phase switch the voltage coil 3 being connected between two of the phases.
