Title: An improved apparatus for protecting electrical apparatus against overload
IPC: H01H83/22
Filed: 1942-07-24
Abstract: 553,154. Electrically-released switches. ELECTRICAL APPARATUS CO., Ltd., BURKE, J. N., WALTON, J. R., and WATTS, T. H. July 24, 1942, No. 10408. [Class 38 (v)] In a device comprising a plurality of currentsensitive members each responsive to one of the currents between which unbalance is to be avoided, and an operative connection between the members and a switch, whereby the latter is operated by excessive uniform movement of the members on overload and by non-uniform movement of the members on unbalance, there is provided, in addition to the normal calibrating member, means for preventing the device being set by manipulation of the calibrating member to a load higher that the maximum intended. In a three-phase application, an insulating base 10 is provided with heat-insulating ribs 12 .. 14 forming compartments receiving bimetal elements 19 in series with heating coils 22 and arranged to deflect to the right, Fig. 7. The upper, free ends of the strips 19 engage slots 25, 26 in a pair of sliding plates 27, 28, the plate 28 having pivoted to it at 29 a bell-crank lever 30, one arm of which carries a pin 31 taking in a hole in plate 27 whereas the other arm carries a roller 32 engaging a movable contact strip 33, Fig. 2. The strip 33 pivots in a hole in a bracket 35 and is urged by a spring 37 in a direction such that its upper end presses on roller 32 and a hook 38 engages over a co-operating contact 39. Normally, therefore, plate 28 is moved by the strips 19 and owing to the restraint imparted by contact-strip 33, the lever 30 causes plate 27 to follow it. If the plate 27 lags, however, lever 30 rotates and roller 32 presses back strip 33 and contact 39 flies up under the action of spring 43 and opens the circuit of, for example, a contactor, Fig. 8. The lag may be due to unbalance causing one or more strips 19 to flex less than the others. Overload protection causing excessive uniform deflection is, however, also caused to impart relative movement to plates 27, 28. For this purpose, a compensating strip 46 is mounted on a bracket 44 pivoted at 45 and is adapted to engage the plate 27. The value of overload is predetermined by a calibrating member 49 pivoted at 50 and having a pointer 51 moving over a scale 52. At the given overload the extension 48 of bracket 44 is stopped by the member 49 so arresting plate 27, whereby continued deflection of the strips separates contacts 38, 39. To prevent excessive movement of member 49, Fig. 7, a stop may be provided, or, alternatively, a stop may be adapted to arrest plate 27 to produce unbalance. Preferably,.however, an unbalance is effected by shaping the. barriers 12 . . 14 so as to limit the movement of strips 19, to an uneven degree, the right-hand strip being allowed the greater movement. A resetting button is provided for the contact 39, Fig. 6 (not shown). The heating coils may be transformer-energized from the respective lines and the invention is applicable also to singlephase and direct-current circuits.

H., 5, Manor Way, Bush Hill Park, Enfield, Middlesex. April 8, 1933, No. 10564. [Class 100 (iii).] Assembling matrices.-The matrix-retaining pawls 3, which are normally located at the receiving end of the first elevator, are arranged to be movable endwise simultaneously with the movement of the line that occurs in quadding or centring, so that the rear end of the line is always supported. The pawls are secured to rails 5, which are longitudinally slidable in the elevator head, and are frictionally connected to the usual forked line-resistant 4 by means of pins passing through slots and provided with friction washers. The pawls are depressed into recesses 6 in the walls of the elevator by the leading matrix of the line, and are there retained by pivoted spring-pressed detents 8. The bars 5 are prevented from moving with the resistant 4 by the engagement of shoulders 9 on the pawls with the ends of the recesses 6. When the line has entered the elevator, the line-delivery finger 14 trips the detents 8 and allows the pawls 3 to engage behind the line. In the further movement of the line along the elevator, the resistant and the pawls move together, owing to their frictional connection. When the line is removed from the elevator by the upper transfer slide, the resistant and the pawls are returned to initial position. A stop-pin is provided to limit the left-hand movement of the resistant.

A disk 3 having funnel-shaped openings 4 fitting over the receptacles and rotating with the measuring-disk is arranged below the fixed disk 6. The disks are slidably mounted on a common shaft 10 and are pressed together by a spring 11 located below an adjustable ball thrust bearing 22, and the hopper and disks are supported by springs 74 on a vertical rod 19. A vulcanized-fibre packing- ring 9 is arranged between a fixed disk 8 carrying the hopper and the rotating measuring-disk 1. The hopper is mounted on a sleeve 64, which may be turned about a fixed boss 65 and retained by a catch, so as to prevent discharge of material when no receptacles are being fed into the machine. The notched disk 12 is formed in two parts, the lower part having radial teeth 27, Fig. 2, adapted to engage the receptacles as they are fed along a groove 29 and move them into the notches 13. A curved spring guide 39 mounted on a spring- pressed carrier 43 may be employed to retain the receptacles in the notches, and a curved groove is provided below the disks to guide the receptacles. Means for feeding the tubes one at a time are provided, the tubes being fed by hand into an inclined shoot 49 and then engaged in succession by a feeding-bar 50 actuated through a bell-crank lever 56 by a pivoted member 52 engaged by the radial teeth 27. The member 52 may actuate also a pusher-bar 51 which moves the tubes one at a time from a tangential discharge groove 30 into a transverse groove. The feeding-bar may be actuated directly by a lever engaged by the teeth 27 and the discharge effected by a suitably curved groove leading away from a tangentialgroove. For cylindrical receptacles, such as cartridge primer bodies, a shoot and curved guide only are necessary, the notches being formed so as to embrace the receptacles and the teeth being adapted to come between them. The receptacles may be supported during their passage through the machine on a table 16, Fig. 1, rotating with the disks, and this table may be vibrated periodically, to facilitate accurate measurement and charging, by means of a hammer 63 mounted on the free end of a pivoted blade 60 resting on a rapidly rotating drum 50 provided with ridges 59. According to Provisional Specification 1320/16, the capacities of the measuring-pockets may be adjusted by means of set-screws.

Filed: 1952-05-05
Abstract: 722,836. Kinematograph apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. April 21, 1953 [May 5, 1952], No. 11316/52. Class 97 (1). [Also in Groups VII and XL (b)] In a step-by-step linear drive arrangement for causing one end of a driving member to execute a substantially rectangular movement for the feed-motion of a film projector, the movement of the driving member is effected by two electromagnets arranged to be energized repeatedly at the same frequency, but with a predetermined phase displacement. The pulses for operating the magnets may be derived from separate sources, or from a single source with means for producing a delay, such as a network or a copper slug on one of the magnets. In the application as shown to a perforated tape transmitter, on the energization of the magnet 1 the armature 7 raises the driving rod 2 bringing the pins 32 into engagement with the feed holes in the tape 31 and at the same time, through arm 23, rocking a pivoted lever 25 about a pivot 26 to move retaining pins 28 downwardly and to depress the pecker rods 30. The energization of the second magnet 3 moves rod 20 to the right so that the rod 2 with its pins 32 in engagement with the tape 31 is moved to the right. The de-energization of the magnet 1 withdraws the pins 32 from the feed-holes and raises the retaining pins 28 and the subsequent deenergization of magnet 3 allows the driving member 2 to move to the left against a stop 33, returning the parts to the normal position shown in Fig. 1. In a modified arrangement, Figs. 5 to 11 (not shown), a lateral extension of the lever 2 carries a ramp or sloping surface engaging the surface of a correspondingly-shaped detent on the lever controlling the movement of the retaining pins and the peckers.

Title: Improvements in or relating to pyrometers adapted to the control of temperature
IPC: G05B1/04
Filed: 1929-04-12
Abstract: 327,861. Bridges, J., and Electroflo Meters Co., Ltd. April 12, 1929. Recording apparatus.-Apparatus for recording and controlling temperature of the type in which a temperatureresponsive index is periodically depressed to record the temperature or actuate the controlling device is provided with means for supporting the index when engaged by the heat-controlling device, to avoid damage to pivots. An index 4, pivoted at 5, moves over a record chart 6 which passes over a horizontal knife edge 3, and an inked ribbon 9 passes across and above, the record chart. The index is periodically depressed by a bar 10 forming part of a frame carried by a spindle 11 with bearings 12, 13 in the side plates 1, 2. The spindle 11 carries a lever 14, Figs. 1 and 2, resting on a rotating cam 15 which allows it to fall once every rotation and thus causes the bar 10 to force the index into contact with the marking ribbon and mark the chart. Another frame 20, 21, 22 is carried by a spindle 17, and carries a projecting part 23 with a roller 24 engaging with another cam 25 so shaped that the frame 20 is allowed to fall slowly once each rotation just after the fall of the bar 10. A threaded rod 26 mounted in the side plates 1, 2 carries a nut 29 having forked arms' 30, 31 adapted to engage, a carriage 33 capable of axial movement along a spindle 34 of D or square cross section. The nut 29 is adjustable by rotating the knob 32. The carriage, Fig. 4, comprises a sliding block 37 and a tongue 39 extending upwards to form an index moving over a temperature scale 40, and downwards into proximity with the index 4. A stop 41 prevents the index from passing beyond it in response to an increase, of temperature beyond that indicated by the tongue 39. A flat supporting bar 42 is arranged level with and behind the knife edge 3 in such a position that, when the rod 22 falls just after the bar 10 has fallen, the resulting movement of the spindle 34 and carriage 33 causes the tongue 39 to pass just behind the bar 42 unless the index 4 intercepts it, when it is caused to slide to a position over the supporting bar 42. The spindle 17 carries an insulating block 44 with two contacts 47, 48, and the spindle, 34 carries an insulating block 49 with one contact 51 normally engaging the upper contact 47, but adapted to be deflected into engagement with the contact 48, when the index 4 intercepts the tongue 39. A pair of normally open contacts 56, 57 are arranged near the cam 15, and the pin 58 on the cam closes these contacts shortly after the spindle 34 and carriage 33 are allowed to fall. The contacts open shortly before the spindle 34 is lifted.
