Title: Method and apparatus for scoring and slotting carton blanks
IPC: B31B50/22
Filed: 1962-06-19
Abstract: 1,014,002. Scoring apparatus. BOX-O-MATIC MACHINE Inc. June 19, 1962 [June 30, 19611, No. 23604/62. Heading B6J. [Also in Division B4] Apparatus for slotting and scoring a blank for subsequent formation into a carton comprises a combined slotting and scoring tool 14, Fig. 1, which is arranged so that, as it is swung downwardly across the blank, its portion C first forms a slot, e.g. 87, Fig. 7, in the blank and its portion S then forms a score line 88. The tool 14 is pivoted at 22 in a housing 15 disposed intermediate the side edges of a work-table which is constituted by two superposed plates 8, 11 and is provided with a central slot for the working passage of the tool, a superposed guard member 20 being arranged around the slot. The slotting portion C of the tool consists of a cutting blade having its edge so shaped (as shown in Fig. 5) that, as the tool is swung downwardly by treadle mechanism 25, 27, successive lengths of the edge all engage the blank at an angle and so exert a cutting, and not a crushing action; the edge has a V-shaped notch and coacts with two spaced cutting dies 68 on the work-table. The scoring portion S of the tool forms an extension of the blades and has a rounded edge for scoring the blank between two spaced creasing dies 76 on the work-table. When forming the slot 87 and score line 88 in the blank, the side edges 83 of the latter is positioned against two abutments 36, 45, Fig. 1, which are disposed on opposite sides of the tool and adjustable in a direction parallel to it to provide for the formation of a slot of the desired length. Adjustability of the abutments is provided by mounting them on respective bars 31, 32 inset in the work-table and adjustable longitudinally by corresponding feedscrews engaging nuts in the bars; rotation of the feed-screw of the bar 31 by a handle 41 adjusts the position of the abutment 36 as shown by a scale 35 and, through sprocket gearing, correspondingly rotates the other feed-screw and adjusts the position of the abutment 45. The blank is arranged to be moved across the abutments to position it for successive slotting and scoring actions by a wheel 56, Fig. 5, which projects through an opening in the work-table into co-operative relation with a wheel 63 adjustably mounted in the tool housing 15 and is adjustably mounted on a shaft 53 arranged to be rotated through sprocket gearing by a handle 52; the co-action of the two wheels not only feeds the blank across the table a distance indicated by a scale 47, Fig. 1, associated with the abutment 45, but forms a score line 83a, Fig. 7. When it is desired to make an additional score line simultaneously with the score line 83a, a further wheel 55 adjustable on the shaft 53 projects through the work-table for coaction with a wheel 62.

Title: Improvements in or relating to electrical remote control systems
IPC: G05D3/14
Filed: 1945-09-13
Abstract: 599,113. Electric control systems. GIBSON, H. C. Sept. 13, 1945, No. 23688. [Class 40 (i)] In a remote control system comprising coarse and fine selsyn transmitters and receivers, a predetermined misalignment of the coarse transmitter and receiver results in the fine receiver being switched over and run as a motor in the corrective sense until the misalignment is reduced to another predetermined value when the normal selsyn and connections of the fine receiver are resumed. As shown, controlling angular movements are applied to the rotor 1 of the coarse selsyn transmitter 2 and through step-up gearing 3, 4 to the rotor 5 of the fine transmitter 6. The high-speed transmitter is normally connected in the usual way to its receiver 9, the rotor 17 of which drives through step-down gearing 10, 11, the rotor 12 of the low-speed machine 7 and the controlled shaft, e.g. a searchlight or gun. The low-speed transmitter stator is connected to the stator of machine 7 through a differential device 8 comprising a stator 13 and rotor 14. For correct correspondence between the transmitters and receivers the resultant fields of the two windings 13, 14 of the differential 8 coincide but any misalignment of these fields produce a corresponding torque. For a predetermined misalignment the torque rocks contact 15 to engage one or other of two contacts which energize a relay 16, contacts 16a, 16b of which break the connections to the high-speed receiver 9, and short-circuit brushes 18, 20 or 19, 20 connected to the rotor 17, which then runs as an A.C. motor in the corrective sense to reduce the misalignment in the coarse selsyn. When this falls to a predetermined amount the contact 15 falls off, whereupon the normal selsyn connections of receiver 9 are resumed to effect fine adjustment.

Abstract: 442,746. Setting bifurcated and tubular rivets. BIFURCATED & TUBULAR RIVET CO., Ltd., 235, Upper Thames Street, London, and PATERSON, L. M., Fox Hill, Aylesbury, Buckinghamshire. Aug. 20, 1934, No. 23958. [Class 43] A machine for setting bifurcated, tubular and other rivets comprises a rivet supporting slide S that is moved into setting position in advance of a co-operating setting tool U and is retained against setting pressure by inclined plane or wedge mechanism operated from the main driving lever of the machine. Rivets supplied from a hopper H are fed down a track J to a feed regulator in the form of a transversely movable slide L which projects the lowermost rivet into an offset portion of the track leading to a horizontal track M. The rivet thus released is moved towards setting position by a push rod r and gripped by a pair of spring jaws G<2> which are pushed apart when the vertically movable rivet supporting slide 5 is raised to move the rivet T to setting position. The slide S is raised, against the action of a spring S<12>, by the tapered end p<1> of a horizontal slide p<2> which is reciprocated by a spring p<3> and a vertically movable slide Q that is operated by connections Q<1>, Q<3>, P, P<3> from a shaft E<1>. When the slide P<2> is fully projected a horizontal portion thereon co-operates with a similar face on the slide S to hold the latter and the rivet stationary during the setting operation. The setting tool U, push rod r and shaft E<1> are operated by a three armed rocking lever D connected by a rod c to spring returned treadle mechanism.

Patent GB-610800-A (GB)
Title: Improvements in or relating to electric resistances
IPC: H01C1/148
Filed: 1946-08-13
Abstract: 610,800. Wire and ribbon resistances; mounting terminals. PHILIPS LAMPS, Ltd. Aug. 13, 1946, No. 24003. Convention date, Nov. 18, 1942. [Classes 37 and 38 (i)] In order that small adjustments in the value of the resistance element may be effected at least one of the terminal members on a rodshaped wire or ribbon wound resistor is in two parts, located side by side along the resistor core, and one of which is for connection to the external lead and the other, adjacent the resistance element and arranged for connection thereto, so formed that it can be connected to the end of the resistance element throughout the periphery of the resistor core. As shown, a terminal band 2 is formed with an integral strap 4 which encircles the core 1 in the manner of an open winding so that the end of the resistance wire 5 may be secured under the strap 4 at any point around the core 1; preferably the winding direction of the strap 4 is opposite to that of the resistance wire 5. The terminal band 2 may comprise more than one integral strap, for example, three, each of which spans a third of the core 1 or Fig. 8 (not shown) two straps, each of which is united to the band at the same point. In other constructions, a resilient wire ringing the core 1 is welded to a terminal band, Fig. 6 (not shown), or clamped in position by means of a bolt inserted through the core 1, Fig. 7 (no shown). The terminal band 2 may be so formed as to completely shroud the end of the resistor core, Fig. 5 (not shown). In a further embodiment, Fig. 1 (not shown), a piece of foil is clamped by a terminal band around the core 1. The external lead may be connected to a soldering tag integral with a terminal band, Fig. 2 (not shown).

Title: Improvements relating to apparatus for protecting polyphase alternating current electrical apparatus, and particularly polyphase electric motors
IPC: H01H83/22
Filed: 1931-08-26
Abstract: 382,695. Protective cut-out arrangements ; automatic circuit-breakers ; thermal switches. ELECTRICAL APPARATUS CO., Ltd., JARVIS, C. M., and BARBOUR, R. H., Vauxhall Works, South Lambeth Road, London. Aug..26, 1931, No. 24046. [Class 38 (v).] To protect a polyphase motor or other polyphase apparatus against single-phasing or fault on one phase and at the same time to provide balanced overload protection thermal devices are provided in each phase and incorrect action due to variation of the ambient temperature is avoided by mounting one of the co-operating contacts of each of the thermal devices on a support which has the same thermal characteristics as the active thermal elements themselves. In the construction shown in Fig. 3, the main switch of the motor is held in the closed position directly or through a trip by a maintaining circuit controlled by the contacts 6, 7, 6a, 7a of three thermal switches one in each phase. One only of the switches is shown. It has two thermal strips 1, 1a both heated directly or indirectly by the current of the same phase. The thermal strip 1 is shunted for current setting by a resistance shunt 3 which may be varied by the conducting slider 4. The other strip is shunted by an inductance 8 with a saturable iron core 9 so that the response of the lower strip, which deals with single-phasing, is made relatively great for low currents. The intermediate contacts 6a, 7 are carried also by a thermal strip 2 which is without energization and serves tocompensate for ambient temperature variations. When the current in any one of the phases is abnormally reduced the corresponding contact 7a leaves the contact 6a and the maintaining or latch-holding circuit is broken to open the main switch. Also, if an undue overload arises one or more of the upper strips bends upwards and breaks the maintaining &c. circuit at 6, 7. In a modification, Figs. 6 and 7, the three thermal strips 10, 11, 12 which in this case are without contacts have their ends lying between two pivoted bars 13,.13a the lower one of which is urged upwards by a spring 16. A switch, arm 18 pivoted at 19 and spring-urged away from its companion contact 17 is normally held in the closed position by a latch member 20 pivoted on the upper bar and passing between pins 22 on the switch arm. The lo.wer end of the latch member is held by the edge of a plate 21 carried by the lower bar. Relative movement between the bars to separate them will release the latch and trip the switch arm. This will be produced in the event of phase failure, the thermal element in the faulty phase relaxing and bending down the lower bar. In the event of overload both bars will move together until an adjustable stop' 34 carried by an unenergized thermal element limits the upward movement of the lower bar. The switch arm is reset by rotating the lever 23 by hand. The choke devices already described may be used also with this arrangement.

Stop-motions, shuttle.-Arms 14a 14b in the path of an incorrectly-boxed shuttle are mounted on a shaft 13 on the breast-beam and are normally held in the position shown in Fig. 1 by a give-way connection 16, 17 by a spring-actuated lever 15 held against a stop 27. When one of the arms is engaged by an incorrectly-boxed shuttle, a link 19 connected to the lever 15 and having a pin-andslot connection with a projection on the weft-fork lever 22 is lowered and brings a projection 20 into the path of a projection 8 on the lay. The lever 22 is thus moved to the left and moves the spring handle 4 to stop the loom.

Filed: 1928-08-23
Abstract: 305,193. Vanitas Co., (Assignees of Rhamstine, J. T.). Feb. 3, 1926, [Convention date]. Darning.-The usual latch needle for mending ladders in silk ware is operated mechanically by a device which ceases to be effective if the pull on the thread approaches its breaking point. The hook-needle b with its latch c is held in a chuck e at the end of a rod f reciprocated by the flexible wire g attached to the wheel k. The wheel k is rotated by a conical friction drive m held up to its work by a light spring n. The drive m is rotated from the motor m by a worm r, cog-shed p and shaft o. If the operator moves the needle so that in pulling up the loops, the breaking strain of the thread is approached, the resistance of the thread causes the drive m to slip inoperatively over the periphery of the wheel k. To stop the reciprocation of the needle, it is sufficient for the operator to place a restraining finger on the chuck.
