Title: Improvements relating to mountings for coils used particularly in radiotelephony
IPC: H01F27/00
Filed: 1925-04-09
Abstract: 254,809. Stanley, F. R. April 9, 1925. Plug couplings combined with electric switches. -Coil-holders for high-frequency transformers and other coils have terminals T, Fig. 1, in addition to the ordinary plug-in elements 1, comprise contacts 7 normally in electrical connection with the plug elements 2 of the holder but disengaged therefrom by engagement with the terminals T when the coil is plugged in. The elements 2 may be connected by screws 5, 6 and brackets 3, 4 to terminals 9, 10 and the contacts 7 may comprise leaf-springs biassed to engage normally the screws 5, 6. The terminals T may be spaced from the coil-plug P<1> and connected to one coil, for example the secondary, of the transformer T<1>, the elements 1 being connected to the other coil. The terminals 9, 10 and contacts 7 are connected respectively between aerial and earth and to the input circuit of a radio receiving set or vice versa, so that, when the transformer T<1> is plugged in, it couples the aerial and input circuits whilst, when an ordinary inductance coil is plugged in, it is connected in both aerial and input circuits by the engagement of the contacts 7 with the screws 5, 6. If the transformer T' is not fully plugged in, the contacts remain in engagement with the screws 3, 4 and the transformer secondary is disconnected from the circuit. In a modification, the leaf-spring contacts are mounted directly on the panel and normally engage the bent-out ends of the brackets 3, 4. In a further modification, the leaf-springs 7 normally engage leaf-springs connected to the screws 5, 6 and are separated therefrom, when the coil is plugged in, by parallel insulating posts on the coil-plug P<1>, the posts having metal terminal plates to contact with the springs 7. In a further modification, the additional terminals T on the coil and the contacts 7 on the holder are replaced by plug-in elements 18,19, 25, 26, Fig. 7. Leafsprings 31, 32 mounted on the plug elements 2 of the holder normally engage the sockets 25, 26 but are separated therefrom when the coil T' is plugged in by engagement of the plugs 18, 19 with insulating studs 33, 34 on the springs 31, 32. The Provisional Specification describes modifications in which one spring-contact is provided on the holder, and in which one of the spring-contacts is affected before the other on progressively plugging in the coil to make various connections with the coil-windings.

Title: Improvements in and relating to electrical circuit-breakers
Inventor: HALL JOHN
IPC: H01H71/10
Filed: 1957-03-27
Abstract: 855,730. Automatic circuit-breakers; contact-members for switches. CHILTON ELECTRIC PRODUCTS Ltd. June 10, 1958 [March 27, 1957], No. 9966/57. Class 38 (5). In an automatic circuit-breaker having a contact-carrying switch arm 2 which may be closed by angular displacement against spring-bias by a cam 3 about an abutment 5 movable under overload conditions to release the arm, the arm comprises an outer part 22 co-operating with the abutment 5 and an inner contact-carrying part 21 capable of limited pivotal and sliding movement relative to the outer part 22 so as to produce a wiping action between the contacts 11, 23. In the arrangement shown, a guide-pin 26 passes through a slot 28 in the inner part 21 and through holes in the outer part 22, the ends of the pin being guided by curved slots 9 formed in the two halves of the outer casing 10. A further pin 27 mounted in the outer part extends through a slot 29 arranged angularly with respect to the slot 28 in the inner part. With this arrangement the inner part pivots with the outer part during the initial closing operation until the edge of the moving contact 23 remote from the cam touches the surface of the fixed contact 11, Fig. 3. Thereafter, as the angular movement of the outer part 22 by the cam 3 about the abutment 5 is completed, the inner part is caused to pivot about the pin 26 and at the same time the relative motion between the pin 27 and slot 29 causes the inner part to slide within the outer part so that the contact 23 slides on the contact 11 as it is turned into full engagement with the contact 11, Fig. 10. In the event of an overload condition, a bimetallic element 8 or an electromagnet 7 turns a pivoted member 6 to move the abutment 5 from the end of the switch arm 2 which then pivots about the cam 3 to open the contacts. During this tripping action the cam 3 is returned to the " off " position and the mechanism is automatically reset. The contacts open in a compartment having spaced plates 101 for arc quenching purposes and gases produced by the arc are discharged through passages 102, 104 and a spring- pressed valve 103 which conserves the pressure of the gases whilst limiting the pressure to a safe value. The casing 10 is in two halves formed with recesses for pivots 31, 61, the curved slots 9, slots for the plates 101 and recess, seatings, outlets &c., for the terminals, springs and the electromagnet. The casing 10 may be provided with " knock-outs to permit the interconnection of the tripping members 6 in the adjacent units of a multiple unit circuitbreaker.

Patent HU-T62419-A (HU)
Title: Optical scanner
Inventor: BUECHLER CHRISTIAN
IPC: G11B7/1378
Filed: 1991-02-06
Abstract: In an optical scanning device, a light beam (L) is focused astigmatically by an objective lens (O) on a record carrier, e.g. a disk (CD), which reflects it onto a four-quadrant photodetector (PD). The astigmatism is produced by an astigmatic element, e.g., a concave or convex cylindrical lens (ZX) or two mutually perpendicular transparent disks located in the beam path. The light beam (L) can be moved radially by a coarse drive. The objective lens (O) can also be moved radially by a fine drive in a direction (W) which makes an angle $g(a) to the normals (R) to the data tracks (S). However, the movement of the objective lens (O) controlled by the fine drive through the angle $g(a) causes imaging defects on the four-quadrant photodector (A, B, C, D), which lead to faulty focusing. To prevent faulty focusing due to imaging defects, a preferred axis of the astigmatic element, e.g., a cylindrical lens or two mutually perpendicular transparent disks, runs parallel to the direction of movement (W) of the objective lens. In the case of a convex cylindrical lens (ZX), the longitudinal axis (LA) is parallel to the direction of motion (W) of the objective lens. In the case of a concave cylindrical lens, the transverse axis is parallel to the direction of motion (W) of the objective lens. In the case of two mutually perpendicular transparent disks, the straight line SG which intersects the two disks is perpendicular to the direction of motion (W) of the objective lens. CD players, video disk players, DRAW disk players, and magneto-optical devices.
