Filed: 1951-11-15
Abstract: 731,254. Autographic registers. LAMSON PARAGON SUPPLY CO., Ltd. Nov. 15,1951, No. 26830/51. Class 16. [Also in Group XVI] An autographic register or like machine. comprises apparatus for controlling the operation of a warning device for indicating when the supply of a transfer web is substantially exhausted, the apparatus comprising a movable control member adapted to press against a portion of the web which has been unwound from a supply roll and is being fed through the machine, the web being in an interposed position maintaining the control member in inoperative position but permitting movement thereof into operative position when the trailer end of the web approaches the movable control member to effect the actuation of a visible or audible warning device each time the register is operated. As shown in Fig. 1, a transfer web 3 is fed from a roll 1, rotatably mounted in a housing 2, over a writing plate 4 where it is interleaved between continuous record sheets fed at right angles thereto, the record sheets being fed a form-length at each operation of the register.while the transfer web is drawn through in small increments, as for instance, described in Specification 678,720. The platen 4 is provided with a slot 5 over which lies a lever arm 6, the lever arms 6, 7 being pivoted at 8 to the register casing and urged by a spring 9 to rotate clockwise. As shown, the arm 6 is supported by the web 3 and a shoulder 10 on the arm 7 supports a pivoted arm 11 which forms part of mechanism for actuating a warning device such as the hammer of a gong. As the trailer end of the web 3 passes the slot 5, the arm 6 is rotated by the spring 9 to pass through the slot 5 and the arm 7 releases the arm 11 which falls into position for engagement, each time the register is operated, by means to move the gong hammer to give an audible warning, and such means may be as described in Specification 678,720. As shown in Fig. 3, the control arm 6 is replaced by a spring metal arm 12 carrying a roller 13 resiliently pressing against the under surface of the web 3 through the slot 5 in the platen 4. The arm 12 bears against an electrical contact 14, earthed to the register casing, which lies under a fixed contact 15 connected in circuit with a warning lamp 16 and a resilient switch arm 17 adjacent the operating shaft 18 of the register which is earthed to the casing. A cam 19 on the shaft 18 wipes across the arm 17 each time the register is operated. When the end of the web 3 passes over the slot 5, the roller 13 rises and the arm 12 presses the contacts 14, 15 together, so that each time the cam 19 passes over the arm 17, the circuit is completed and the lamp 16 is lit up to warn the operator. As a modification, the lamp 16 may be arranged to be continuously lit immediately the contacts 14, 15 are closed.

IPC: B65B43/30
Filed: 1967-06-09
Abstract: 1,224,317. Bag filling machines. REED PAPER GROUP Ltd. 29 May, 1968 [9 June, 1967], No. 26846/67. Heading B8C. Bag filling apparatus includes means to raise a flat bag to an opening position adjacent a filling spout, suction devices to open the bag by pulling apart the bag sides and a filling spout movable relative to the bag to enter the mouth. A stack of bags 8 enters the machine on a conveyer 9 and is checked by a stop beneath a suction cup 6 on a pivoted arm 2. The cup grips the bag and retracts and the arm pivots upwards until the cup is aligned with a further cup 12 adjacent a bag guide 10. The ends of the bag mouth are gripped by pairs of jaws 17, 18 on a carriage 15 running on rails 14 between the bag pick-up position and a filling position. The carriage supports also a filling spout 16. The cups move apart and the pairs of jaws approach each other so that the bag mouth is opened, permitting the spout to be lowered into it. The carriage now moves to beneath a hopper 48 and filling commences. During filling, the bag is supported by a conveyer 31 stationary in its normal direction of travel but vibrating to settle the contents and rising corresponding to diminution in height of the bag as it fills. After filling, the pairs of jaws move apart and then separate, thus flattening and releasing the bag mouth, the spout rises and gripper conveyers 34, 35 close in on the mouth to convey it to sewing means (not detailed) or a heater sealer. The conveyer 31 supports and moves the bag base until the weight of the bag is taken by a further conveyer beneath the sewing head. A single pair of cups 6, 12 may be used, but in a modification, Fig. 7, three pairs are employed, the central ones 51, 54 being joined to their reciprocating mechanisms but the others 50, 52, 53, 55 being supported from the cups 51, 54 by flexible plates 56, 57. As the cup assemblies part to open the bag mouth, stops 59 engage the plates causing the mouth to be opened to the shape shown.

Title: Process for welding aluminium
IPC: B23K5/12
Filed: 1923-10-27
Abstract: 206,162. Metallisation, Ltd., (Assignees of Meitrer'sche Akt.-Ges. fur Spritzmetall- Veredelung). Oct. 27, 1923. Uniting by fusion.-In welding aluminium, the parts are heated nearly to softening point and the oxide layers are then broken so as to allow the parts to unite, by projecting thereon a stream of finely divided material such as fine sand or metal dust, e.g. aluminium dust or other metal which alloys therewith. The stream may be projected by hot compressed-air or other gas, and the metal dust previously heated. The metal-spraying process described in Specifications 28001/12 and 25132/13, [both in Class 82 (ii), Washing granular &c.], may be used for the purpose, the spraying pistol being preheated and held close to the joint so as to prevent premature solidification. In welding thin walled articles, preheating of the work may be dispensed with, the heat being furnished by the spraying flame, and in welding thin sheets the contact edges may be previously turned up to form a low ridge which is fused by the spraying flame. Specification 5712/10 also is referred to.

Title: An improved arrangement in commutator machines connected in cascade to induction machines
IPC: H02K17/38
Filed: 1927-10-12
Abstract: 279,086. Allmõnna Svenska Elektriska Aktiebolaget. Oct. 15, 1926, [Convention date]. Alternating-current induction and commutator machines.-In an arrangement comprising a commutator machine cascaded with an induction machine and having its stator excited by a frequency converter, the frequency converter is connected to the mains through a variable-ratio transformer and to a series transformer carrying the load current of the induction machine in its primary side, this transformer having two secondary windings, one in the primary and the other in the secondary side of the variable-ratio transformer. The excitation of the commutator machine is thereby rendered independent of the frequency of the exciting voltage. In the form shown in Fig. 1, the commutator machine 2 cascaded with the induction machine 1 has an exciting winding 4 fed from the frequency converter 5 in addition to a series compensating or compounding winding 3. The converter, which is preferably driven from the induction machine 1, is fed on its slip-ring side through a variableratio transformer 10 from the mains 9 supplying the machine 1, and has a stator winding 7 connected to the brushes 6 and the stator winding 4 of the cascaded commutator machine 2. The positions of the winding 7 and brushes 6 are so chosen that their respective voltages are in quadrature and correspond to the inductive and ohmic drops in the exciting winding 4. A series transformer has its primary winding 11 in the main motor circuit and two secondaries 12, 13 in series with the two windings of the transformer 10. This double secondary arrangement allows load phase compensation to be effected in addition to compounding of the main machine. The Specification as open to inspection under Sect. 91 (3) (a) contains a claim for a group comprising an induction machine cascaded with a commutator machine and excited in its stator by a. frequency converter having a stator winding which is in series with its rotor winding in such a manner as to generate substantially the ohmic and reactive components of the excitation power. It also describes the arrangement shown in Fig. 2 (Cancelled), in which the commutator machine 2 of Fig. 1 is omitted, the frequency converter 5 is driven by a synchronous motor 14 and its slip rings are connected to a synchronous generator 15 driven by the main machine 1. The voltage of the converter is regulated by a resistance 16 in the exciting circuit of the generator 15. This circuit may be wound in two parts at rightangles to each other, thereby allowing inde-pendent control of the two voltage components supplied to the converter. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,242,384. Control of D.C. motors. SEVCON ENG. Ltd. 13 Sept., 1968 [14 June, 1967], No. 27412/67. Heading H2J. A control circuit for effecting regenerative braking of a D.C. series motor 1, 2 having reversing contacts 3, 4 for reversing the armature and field connections 1, 2 comprises a pulsing controller 7, 11, 12, 13, 14, 25, 26 which provides a path which can be pulsedinto conduction to short circuit the armature and field windings when contacts 3, 4 are in the regenerative braking position shown; a diode 6 connected in series with armature 1, field windings 2 and a battery 5 to prevent current flowing from the battery to the armature and field windings when the contacts 3, 4 are in the regenerative braking position; and control means which ensures that when the path provided by the pulsing controller is open-circuited whilst the motor is operating as a generator, the voltage generated by the armature does not exceed the voltage of the battery 5. The pulsing controller comprises thyristors 7, 13 fired simultaneously by an oscillator 26 whose frequency is manually controlled, a commutating capacitor 11, and a turn off thyristor 12 fired by an oscillator 25 at a fixed interval after firing of thyristors 7 and 13 to turn off thyristor 7. The control means comprises a zener diode 16 connected to the armature 1 and base of a transistor 17 whose collector-emitter circuit shunts the triggering circuit of thyristor 7. If during braking the armature voltage exceeds the breakdown voltage of zener diode 16, transistor 17 is rendered conductive and shunts oscillator 26 so that conduction of thyristor 7 is suppressed until the armature voltage falls to such a level that when the thyristor 7 is finally commutated the armature voltage is less than the battery voltage. In an alternative arrangement the turn-off thvristor 13 is fired earlier than usual should the breakdown voltage of zener diode 16 be exceeded so that the commutation of thyristor 7 is advanced.
