Patent GB-829217-A (GB)
Title: Improvements in or relating to electrical regulating apparatus
Inventor: MARTIN LEONARD JOHN
IPC: G05F1/32
Filed: 1957-02-11
Abstract: 829,217. Transformer arrangements. BRENTFORD TRANSFORMERS Ltd. Dec. 31, 1957 [Feb. 11, 1957], No. 4659/57. Class 38 (4). A voltage or current regulating apparatus comprises series-connected transductors 3 for regulation over a range from maximum down to a certain value and a shunt connected variable impedance 9 for regulation from that value down to zero. The control windings 4a, 4b, 4c of the series-connected transductors 3a, 3b, 3c are fed from a regulator 5a, 5b, 5c over rectifiers 8a, 8b, 8c so that when the movable contacts 7a, 7b, 7c are at the top (as shown) of the regulator windings the effect of the control windings 4 on the transductors 3 is such as to cause minimum impedance of the transductor and hence maximum voltage or current at the load 2a, 2b, 2c. As the contacts 7 move down the regulator 5 the impedance of the transductors 3 increases, thereby reducing the current or voltage at the load 2 to some lower value. When the contacts 7 reach the bottom of the regulator 5, further movable contacts 12a, 12b, 12c, associated with a shunt connected transformer 9, begin to move down the regulator 5. When the contacts 12 are at the top of the regulator 5 the impedance of the shunt-connected transformer is high and hence its regulating effect is materially low. As the contacts 12 move down the regulator 5 the impedance of the transformer decreases and thus gradually reduces the current or voltage at the load 2 from the lower value, obtained by the transductor, to zero.

Title: Improvements in connection with the Filling of Explosive Shells.
Inventor: THOMAS THOMAS
IPC: F42B33/02
Filed: 1916-03-30
Abstract: 101,125. Thomas, T. March 30, 1916. Explosives.-In filling a shell A with explosive B, the wooden plug C used sometimes breaks. According to the invention, a broken plug C is removed by means of a screw D which is screwed into the plug and then pulled from the shell. In the form shown in Fig. 1, the screw D has an eye E connected by a sling G to a wooden lever H fulcrumed on a pillar J. The shell is lifted by a sudden slight jerk of the lever H, this causing the withdrawal of the broken wooden plug. A sand bag K beneath the shell protects it from damage. In a modification, the screw D is screw-threaded along its length and is pulled out gradually by means of a nut screwed thereon and bearing against a plate threaded over the screw and abutting against the nose of the shell; the outer end of the screw is made square in section to facilitate the operation of screwing it into the broken plug.

Title: A device, applicable to typewriting machines, for counting the lines and announcing the end of the pages
IPC: B41J29/48
Filed: 1925-02-21
Abstract: 238,141. Seigneur, A. Feb. 21, 1925. Counting-apparatus; exhaust of paper, indicating; alarms.-A line-counting mechanism for indicating in typewriters the number of line spaces remaining on a sheet, and, by means of an alarm bell. announcing the end of a page, is mounted upon an axis 4 which forms an extension of the roller platen axis and is rotated for line-spacing by a knob 12, the number of line spaces remaining being indicated upon a barrel 8 which is free to turn on the axis 4 and is connected bv a reduction train 9, 20, 19 to a free pinion 7 carrying spring-pressed pawls 6 engaging a ratchetwheel 5 secured to the axis 4. The barrel 8 is secured to or integral with the pinion 9 and is connected to one end of a clock spring 10, the other end of which is secured to a wall 2 within the casing 1 enclosing the apparatus. The engagement of the pawls 6 and the ratchet-wheel 5 is controlled by a slidable sleeve 15 provided with a tapered edge 16 which engages rollers 17 on the pawls and lifts them from the ratchet-wheel to disengage the counting-mechanism when the sleeve is moved towards them, a movement in the reverse direction allowing the pawls to drop. The sleeve 15 is provided with inwardly projecting radial screws extending within oblique guide slots 14 in a stationary collar 13 on the end wall 3 of the casing, so that when the sleeve is rotated through about 60‹ by lifting a handle 21 attached thereto, it is moved laterally away front the ratchet-wheel 5. The handle is moved against spring tension and is retained in the raised position by means of a catch. Two rows of numerals may be provided around the periphery of the barrel 8, with maxima, for example 30, 59, corresponding respectively to the number of widely spaced or closely spaced lines upon a page. The initial position of the barrel is set according to the number of lines required to be typed, by means of a setting-mechanism comprising a crown 29 which is rotated upon the wall 2 and carries an abutment 31 which lies in the path of an abutment 32 on the barrel 8. The projection 31 on the crown can be moved within an arcuate notch in the wall 2, carrying the barrel with it until the requisite number upon the barrel appears through the window of the casing. The crown is clamped in the set posi. tion by a headed screw 30 which also serves as the setting-handle, and, at its inner end, is reduced to engage one of a series of holes at linespace intervals in the notch in the wall 2. During the operation of the device the gearing and the barrel 8 are rotated against the tension of the spring 10, until, the last line being reached, the abutment 32 on the barrel strikes a projection on the catch holding the clutch handle 21, which is thereby released and is pulled back to its initial position, releasing the ratchet clutch and suriking the alarm bell at the end of its movement. The clock spring 10 then returns the barrel 8 to its original set position.

Title: Improvements in or relating to enclosed electric switchgear
IPC: H01H21/06
Filed: 1936-02-19
Abstract: 470,191. Switch cases and covers. WALSALL CONDUITS, Ltd., MILLARD, A. E., and COURT, R. A. B. Feb. 19, 1936, No. 4995. [Class 38 (v)] In switchgear having an interlock between the switch operating member and the hinged cover an interlocking bar is positively associated with the handle or member for operating the switch the said bar being engageable with a part on the lid or cover to lock the latter positively in the closed position on movement of the switch to the closed position and a further part is adapted positively to prevent movement of the switch means to the closed position when the lid or cover is open, fastening means being also provided for clamping the lid or cover in the closed position independently of the said interlocking means. As shown in Figs. 1 and 2, the bar 23 for operating the knob 22 of a tumbler switch is mounted in bearings 25, 27 in the case 11, and when as shown, the handle 28 is depressed to move the switch to the " on " position, the bar passes through an aperture in a member 30 attached to the underside of the hinged cover 12 so that the latter is locked in the closed position. When the switch is moved to the " on " position, however, the lid may be raised as shown in Fig. 3. In this position, however, a pair of lugs 32 projecting from the side of the cover move into the path of movement of the switch-operating handle 28 so that no closure of the switch can take place until the cover has been re-closed. The cover is also retained in the closed position by a number of studs 15 inserted through. holes in the flange 16 on the lid and engaging holes in the flanges 17 of the box. The heads of the studs 15 are formed with heads 18 operable only with a special tool. In this arrangement the casing contains fuses in addition to the switch under a single hinged cover, but in a modified form, Figs. 5-10 (not shown), the fuses are in a separate casing with its own cover. A combined interlock is provided in this arrangement for the switch and fuse covers by a pair of rods sliding in lugs at the outer sides of the casings, and driven directly from the operating mechanism of the rocking switch shaft. The fuse covers 42, Fig. 8, are provided with apertured lugs 50 formed with lateral openings 53 adapted to slide over the recessed sides 49 of the interlocking rod 40 when the switch is moved to the " open " position. This arrangement may be modified, as shown in Fig. 14, by the provision of a segment 66 on the fuse cover which projects in a recess 67 formed in one of the sliding interlocking rods 54 and so prevents the movement of the switch while this cover remains open.
