Title: Improvements in or relating to machines organised for folding the margins of workpieces
IPC: A43D8/40
Filed: 1958-02-12
Abstract: <PICT:0910746/III/1> <PICT:0910746/III/2> In a machine for folding the margin of a workpiece W (see Group VIII) molten thermoplastic adhesive is applied to the workpiece margin through a nozzle 12, Fig. 9.  The adhesive is fed in rod form, by a pair of intermittently driven feed rollers, to melting apparatus and thence extruded from the nozzle 4 by an intermittently driven pump, in a manner similar to that dissolved in Specification 749,892.  A shaft 152, Fig. 4, driving the adhesive feed rolls and pump, and an adhesive control-valve 166, 168, Fig. 9, are under the control of a solenoid-operated lever 164, Fig. 4, which is raised when the machine is started; when the machine is stopped, lever 164 is lowered to disengage a latch 158 from a notched oscillating lever 156 and interrupt the drive therefrom to shaft 152, and a bell crank 192 is moved to release a cable 174, Figs. 4 and 9, and close valve 166, 168.  The workpiece W is advanced intermittently by an oscillating hammer and anvil and by an intermittently driven feed wheel 46, Fig. 9, which cooperates with a rotary disc 42 in the surface of the feed table 32.  Specifications 544,010, 687,861 and 727,202 are referred to.

Abstract: 348,539. Necklaces and other jewellery chain structures. COLLINS, W. H., Excelda Works, Rookery Road, Handsworth, Birmingham. Feb. 12, 1930, No. 4708. [Class 43.] In necklaces, bracelets, and other chain structures and articles of jewellery comprising elements 1 to receive jewels or stones, links 3, and washers or coupling members 9 mounted in the elements and connecting the links together, the washers 9 each comprise an open or gapped loop, Fig. 8, or a loop having open hooks 10, Fig. 3, for receiving the links 3.

Filed: 1952-02-22
Abstract: 709,776. Self-wringing mops. TRINDL, J. H. Feb. 22, 1952, No. 4714/52. Class 19 A self-wringing mop comprises two plates 11, 12 of arcuate form, hinged together along a longitudinal axis by means of a pin 14. The hinge lies within a recess in a block of cellulose sponge 13 which is attached to the plates 11, 12 by means of screwed studs 34 and nuts 25, at points spaced away from the axis 14. The studs 34 are carried on strips 33 which are held by a doubled canvas backing member 31 cemented to the sponge 13: the member 31 also passes around and retains cord or rubber bumpers 32. The plate 12 carries a handle socket 15 and the plate 11 lugs 17 to which is pivoted a link 22 whereby the plate 11 may be rotated to wring the mop. The remote end of the link 22 is pivoted to an operating lever mounted on the handle, Figs. 1-3 (not shown). The arrangement is such that, during wringing, the pin 14 travels away from the sponge 13 and the application of excessive pressure in this region is avoided.

Title: Improvements in electrical frequency stabilising systems
IPC: H02J3/08
Filed: 1944-03-14
Abstract: 579,940. Automatic control systems. MILSOM, F. R., FURZEHILL LABORATORIES, Ltd., and SMITH & SONS (ENGLAND), Ltd., S. (formerly SMITH & SONS (MOTOR ACCESSORIES), Ltd., S.). March 14, 1944, No. 4765. [Class 38 (iv)] Frequency-The output frequency of a rotary transformer is stabilized at the balance frequency of a frequency-responsive A.C. bridge circuit, supplied at the output frequency, the output of which reverses in phase as the input passes through the frequency value at which the bridge is balanced and controls a reversible motor driving the rotor of the transformer. In Fig. 1 an A.C. supply 10 of variable frequency or of frequency other than that desired is connected to the stator of an induction type frequency changer 11, the rotor winding of which provides an A.C. output 12. The frequency of this output is stabilized by a Wien bridge 13 of the resistance-capacity type, connected to the output, which is balanced at the desired frequency but which, on frequency deviation, supplies, through an amplifier 14, a balanced modulator 15 controlling a reversible-geared split-field D.C. motor 18 driving the rotor of the frequency changer so as to correct the deviation. The output of the bridge is dependent in amplitude and sense on the frequency correction required and, through the modulator, which may be of the type in which a pair of valves respectively energize the motor fields, causes the motor speed and direction of rotation to be that necessary for correction. In a modification the balanced modulator is dispensed with and the amplifier output supplies one phase of a two-phase induction motor for driving the rotor, the other phase being supplied from the stabilized A.C. output. The required quadrature phase relationship between the two motor supplies is obtained by a phase shift in the amplifier. A polyphase induction motor may be employed in a similar arrangement. The bridge may be temperature-controlled.

Title: Improvements in typewriting machines
IPC: B41J11/24
Filed: 1946-02-15
Abstract: 621,856. Typewriters. TRIGGS, W. W. (Underwood Corporation). Feb. 15, 1946, No. 4770. [Class 100 (iv)] In a typewriter for printing on continuous webs interleaved with carbon sheets and wherein the carriage return is power-operated, a web-registering device which is moved to an extended position for the relocation of the webs relatively to the carbons is provided, but such movement is prevented whenever the carriage-return means is effective. As shown, the platen 22, a paper table 20 and a gauge-bar 44 carrying a gauge 43 are mounted in sideplates 18 pivotally mounted at 25 on the carriage. These parts are secured in their normal operating-position by slots 32 on spring latches 27 engaging pins 26 on the plates 18. To move the parts in order to free the webs and reposition them, the bar 44 which is capable of slight independent pivotal movement, is lifted and a cam 46 attached thereto engages a pin (47, Fig. 5, not shown) on one of the latches 27 to lift the latter and free the plates 18. During the next part of the movement, the pins 26 ride along the surface 52 of the latches 27. At the same time, catches 53 rise to engage projections 54 on the latches to retain them in released position. The catches. 53 are normally depressed by a link 51 pivoted to the plates 18 and to a lever 48 which engages a fixed member 50 to limit the movement of the plates 18. Extending beyond the pivot 30 of the latches and integral with one of them is an arm 120 connected by a link 121 to a lever 125 carrying a rod 123 coextensive with the carriage and bearing on one end of a cranked lever 129 ,mounted on the frame, so that movement of the parts 20, 22, 44 to extended position causes the end 128 of the lever 129 to move upwardly. The carriage-return mechanism is as described in Specification 530,359 which includes a linkpart 111 which is moved endwise when the power-mechanism is effective for returning the carriage. In such position, it prevents upward movement of the end 128 of the lever 129 and therefore prevents movement of the parts 20, 22, 44 to extended position. Similarly, if the parts 20, 22, 44 are in extended position, the end 128 will block endwise movement of the part 111 and prevent the carriage-return mechanism from operating. As shown, operation of the line-spacing mechanism which, according to the Specification mentioned, precedes the carriage-return, is not suppressed when the parts 20, 22, 44 are moved, but means could be provided for this purpose if desired. The carriage for holding the carbon sheets may be as described in Specification 23349/14, [Class 100 (iv)].

Devices 3 and 4 temporarily secure the unit 1 to the container or the unit may be mounted on a vehicle having clamps to hold the container. The brushes of the elements contact the entire inner periphery of the container either by the provision of a double element (Fig. 2) where the upper element consists of two frame halves 14 and 17 connected together for movement by the piston system 12, 13, and the lower element, similarly constructed, is rotated through 90 degrees with respect to the upper element, or by an element (e.g. Fig. 3) consisting of at least two frame parts with overlapping portions at slits 27 and 28. A pressure indicator system may depressurize all the piston systems when a preselected pressure has been exceeded and blowing and exhaust devices. nossiblv with the same nozzles to be arranged in the container, may be employed to alternately pressurize and evacuate the container. Protective elements may guard the unit parts from excessive heat from a hot container.
