Title: Pushbutton octuated excess current switch with thermal tripping
IPC: H01H71/02
Filed: 1976-01-06
Abstract: 1502201 Thermally-tripped circuit breaker ELLENBERGER & POENSGEN GmbH 6 Jan 1976 [23 Jan 1975 14 March 1975] 00380/76 Heading H1N A trip-free, push-button actuated switch with thermal overload trip includes a bimetallic element which can readily be assembled and adjusted. Actuation of the switch to close the contacts is by depression of a push-button 7 and rod 7<SP>1</SP> having at its lower end a rigidly connected bridge 8 formed with a pair of lugs 9, which pivotally support a contact bridge in the form of a cranked lever 13, and also formed with a projecting driving member 10 which entrains a dog 11 on the limb 12 of the contact bridge and thereby carries it down against the action of springs 24 and 25, until a protuberance 19 on the limb 14 engages beanth a latch 20 so that, on release of the push-button, the return action of the springs against the contact bridge will swing it clockwise and contact 15 snaps into engagement with fixed contact 16 (Fig. 4, not shown). The latch 20 is carried near the end of a bimetallic strip 21, clockwise bending of which effects tripping. A manual trip may also be fitted (57, Fig. 4). The strip 21 may be directly or indirectly heated and may take the form of a plurality of series-connected parallel strips (Figs. 8-10, not shown). It comprises a main vertical portion bent at right angles to form a horizontal portion 27, bent again 28 and secured to a carrier 30, 31 located in a recess 32 and connected to a terminal 33. The horizontal portion 27 is loosely pivoted between semicircular projections 34, 35 situated vertically below the latch 20 and adjustment of the trip setting is obtained by means of a screw 36 by which the carrier 30 may be tensioned to exert an anticlockwise pull on the bimetal strip 21 and so bias it against a stop 37. A U-shaped ambient temperature compensating bimetal strip may be inserted between the carrier 30 and the trip strip. The casing may be provided with resilient plastics serrated arms for mounting the switch into apertures (Figs. 5 and 7, not shown) or the terminals may be adapted for mounting it on to a printed circuit board.

Title: Improvements in control electrodes for space current devices
IPC: H01J19/38
Filed: 1926-01-07
Abstract: 245,779. British Thomson-Houston Co., Ltd., (Assignees of Prindle, R. B.). Jan. 8, 1925, [Convention date]. Vacuum tubes. - A control electrode consists of metallic rods 1, Fig. 1, and tubular metallic terminals 4 secured together, without welding, to form a cage-like structure which can be dismounted without deformation. Additional spacing members may be interposed between the terminal pieces. The rods 1 may be bent into hooks at the ends which are inserted in holes or notches in a short cylinder 3, Fig. 5. They are spaced apart by sliding over the cylinder 3 a second cylinder 4, equal in thickness to the rods and slotted for their reception. A third cylinder 5 is then slid over the cylinder 4, and all the cylinders 3, 4, 5 may be secured together by a single rivet 6. Slots 11, Fig. 1, for use in attachment to supports are made in the cylinders 4. The intermediate spacing devices may consist of two rings 7, 13 notched externally to take the rods 1, and an intermediate external ring 9 engaging inward bends of the rods, which may be annealed after shaping. The rings 7, 9, 13 are placed in position successively, before mounting the rods 1 in the terminal pieces. One of the rings 7 or 13 may be omitted. The notches in the rings 7, 13 may be deep, and the bends in the rods 1 of such form that there is but little variation in the internal diameter of the electrode. The electrode may be conical instead of cylindrical. Tungsten may be employed for the electrode proper, and molybdenum for the terminal pieces.

Title: Improvements in or relating to ammunition projectile fuzes
IPC: F42C15/26
Filed: 1928-01-07
Abstract: 283,854. Soc. Franþaise des Munitions de Chasse, de Tir, et de Guerre, (Assignees of Auriol, L.). Jan. 17, 1927, [Convention date]. Projectile juzes.-Sensitive percussion fuzes, for artillery shells or aircraft bombs, are so constructed that when the fuze is armed during the flight of the projectile, the percussion cap and the firing pin are brought into contact, and the tendency of the percussion cap to move forward is checked during flight solely by the firing pin. By this a very small further relative movement of the firing pin and cap is sufficient, when impact occurs, to cause ignition. Fig. 1 shows a construction in which the firing pin or hammer 2 is carried by a head 3 which is caused by a spring 6 to protrude from the fuze body 1, a guide-pin 4 passing through slots 5 in the head 3. The percussion cap 12 is mounted in a holder 13 and is normally kept out of reach of the pin 2 by means of an inertia sleeve 10 and a tongued clip 8. On discharge of the projectile, the fuze is armed by the setting back of the sleeve 10, and subsequently, during flight, the parts 12, 13 with the members 8, 10 locked thereto, creep forward until the cap 12 makes contact with the point of the pin 2. Impact with an obstacle causes ignition by the driving inwards of the head 3 and also by the further forward movement of the member 13 &c. due to inertia. Fig. 2 shows a fuze in which the striker 3 is secured by a shear pin 16, and in which a safety-device comprising a centrifugal tape 17 is also provided. In this fuze, the percussion cap 12 is slidable in the holder 13, and is pushed forward by a spring 18. The action of the fuze is similar to that of the fuze shown in Fig. 1, apart from the percussive ignition, which is caused only by the direct action of the head 3. Fuzes are described. in which the head of the firing pin is kept forward, during flight, by the action of the air. Fig. 4 shows a fuze of this kind in which the firing pin 2 is attached to a very light stamping 3; this, together with the pin 2, is free in the body of the fuze, and during flight the head 3 is kept towards the front. The percussion cap 12 is normally held back, against the action of a spring 25. by centrifugal bolts 23 surrounded by an elastic band 24 or an inertia ring. After discharge of the projectile, when the cap 12 has been freed by the bolts 23, it is moved forward by the spring 25 into contact with the point of the pin 2. A slight blow is then sufficient to cause ignition. The arming devices of the fuzes may be modified according to requirements. For example, in the application to an aircraft bomb, a safety pin which is pulled out by the fall of the bomb may be used, with a screw arming in addition.

Title: Improvement in electric flasher device
IPC: H01H61/06
Filed: 1953-01-09
Abstract: 729,250. Thermal switches; switches, partly electromagnetic. HOLLINS, J. R. Jan. 9, 1953 [Jan. 9, 1952], No. 724/53. Class 38 (5). A switch operating substantially the same as that disclosed in Specification 729,249 has its armature 32 pivoted on an arm 28 of the frame 17, the armature carrying a spring 37 supporting the contact 34. On expansion of the resistance wire 30, contact 25 engages contact 22 whereupon signal lamps 13, 13<SP>1</SP> are lit and the armature is attracted to engage contact 27 with contact 25 and close contacts 34, 36 to energize the pilot lamp 12. On cooling of the wire 30 the armature 32 follows the movement of the spring arm 23 by pivoting counter-clockwise, the relative movement between the contacts 25, 27 causing cleaning of their surfaces. Eventually the contacts 25, 27 separate and the cycle repeats. In a modification, Fig. 2, an arm 52 mounted on an insulating block 51 and connected to a further pair of signal lamps 57, 57<SP>1</SP>, carries a contact 53 co-operating with a back contact on the spring 37. When switch 15<SP>1</SP> is closed lamps 57, 57<SP>1</SP> are illuminated and are extinguished when the lamps 13, 13<SP>1</SP> are illuminated and the armature is operated, thus the two pairs of lamps flash alternately.

Title: Improved means for controlling the volume of sound reproduction by talking film apparatus
IPC: H03G1/02
Filed: 1930-01-08
Abstract: 347,125. Reproducing music &c. SCHIFFL, F., 11, Elsworthy Terrace, Hampstead, and HEYL, E. O., 15, Down Street, both in London. Jan. 8, 1930, No 762. [Class 40 (iv).] For enabling the volume of sound emitted by talking-film apparatus to be controlled by an operator in the auditorium, a rheostat in the amplifier or loudspeaker circuit is rendered adjustable from a distance by providing in connection with the spindle of the rheostat a ratchet wheel or equivalent which can be turned in either direction to a desired extent by means of pawls or the like controlled, in the manner described below, by the plungers of two solenoids, either of which is energized at will when one or other of a pair of switches is closed. In the construction shown, two solenoids e are arranged below and on opposite sides of a ratchet wheel b, which is mounted on a spindle a, connected by a flexible coupling to the rheostat (not shown). Each solenoid plunger f is attached to a rod g carrying a head h which is within a guide tube m. A slidable bifurcated block n, in which is pivoted a pawl q, is also located in each guide tube, and the lower end of the pawl, as well as the adjacent surfaces of the parts h, n, are formed with correspondingly angled faces, j, k. When either solenoid is energized, its plunger rises and lifts the pawl q until the block n is stopped by an adjustable abutment w. At the same time, the pawl is tilted by the engagement of the inclined faces thereon with those on the head h and is moved into contact with a tooth of the ratchet wheel, which is rotated as the plunger rises. The ratchet wheel can thus be moved, step by step in either direction, to adjust the rheostat as desired. Instead of toothed paw and ratchet mechanism, a friction wheel device may be provided.

Title: Commutative magnetic disk driving device
Inventor: YUASA MASAHIRO
IPC: G11B5/09
Filed: 1989-01-05
Abstract: PURPOSE:To increase a recording capacity for a magnetic disk medium without complicating the subject device by setting a specific azimuth angle at a pair of magnetic heads, and making an access to the medium at every other track. CONSTITUTION:R/W gaps 12a and 12b of R/W cores 11a and 11b have the same angle alpha (>0) with respect to a normal passing through a center CN of rotation. That is, the prescribed azimuth angle alpha is applied in the same direction from either one head to respective magnetic heads 10a and 10b arranged on both sides of the magnetic disk, and the magnetic disk is controlled so as to be recorded at every other track. When the magnetic disk is recorded from one surface to the other surface, or vice versa, the magnetic disk is recorded by shifting one track. Thus at the time of reading, even when the magnetic head slightly shifts to the adjacent track, the effect of the adjacent track is suppressed, a track density is increased, and the large recording capacity can be written on the disk.

Title: Structural material holding tool
Inventor: MIYAZAKI ISAMU
IPC: B63B9/06
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To provide a compact and lightweight structural material holding tool which is available inexpensively and which has versatility, and which facilitates a structural material settin-up work. SOLUTION: The structural material holding tool is a tool for setting up and holding a structural material 1 in the direction of its height, and has first and second members 4, 5 to be used in combination with each other. These members have first and second baseplate parts 41, 51 provided with engaging parts 43 and 53 respectively, and first and second receiving frame bodies 42, 52 having first and second receiving faces 42a and 52a facing each other leaving a space (d) between the receiving faces so as to receive a web part 11 of the structural material 1. Thus, by only arranging the first and second members in combination with each other, the structural material can be put and erected in the space (d) between the receiving faces, on the baseplates.  Because the engaging parts can be easily separated after the structural material is temporarily welded, the structural material setting-up work can be easily performed. Because the web part of the structural material is supported, the holding tool can be compact and lightweight, and it is easy to handle and can be obtained at a low cost with versatility.

Title: Terminal switching system for remote diagnosis
Inventor: OTSUKA MAMORU
IPC: G06F11/22
Filed: 1989-01-06
Abstract: PURPOSE:To select and connect a terminal equipment having an attribute which coincides with a terminal attribute by reading and discriminating automatically a terminal attribute of a line connecting part of a system to be diagnosed before starting a remote conversational operation in a remote diagnosis. CONSTITUTION:When a start command for executing a remote diagnosis is inputted from one of terminals 181-18n connected to a diagnostic system 11, a terminal switching device 16 outputs a line connecting request to a line connecting part 15 of a designated system to be diagnosed 12. Subsequently, the connecting part 15 outputs a permitting signal to the device 16, and when this permitting signal is received, the device 16 issues a command for reading a terminal attribute of the system 12 to the connecting part 15, and receives its terminal attribute. Next, the device 16 which receives the terminal attribute retrieves the terminals 181-18n having an attribute being equal to this terminal attribute, and connects terminal connecting parts 171-17n corresponding to its terminal. In such a way, since a difference of the terminal attributes in the remote diagnosis can be prevented in advance, a data omission, missing and an error caused by the difference of the attributes can be prevented in advance.
