Patent GB-1321959-A (GB)
Title: Foil feed device
Inventor: WETZEL R
IPC: B41F19/06
Filed: 1971-11-12
Abstract: 1321959 Feeding webs HEIDELBERGER DRUCKMASOHINEN AG 12 Nov 1971 [25 Nov 1970] 52670/71 Heading B8R A foil is intermittentty advanced to processing apparatus, e.g. an embossing printing machine, in a programmed cycle in which the advances may be of different lengths, this cycle being repeated constantly. Thus the cycle may consist of several "normal" advances followed by a longer advance; a further, still longer, advance may also be included. As shown, a feed roller 1 for the foil 3 is provided with two drive sprockets 5, 6 linked by chains 15, 9 to respective rocker arms 11, 13 which are reciprocated by a coupling 12 driven by a crank (not shown). A latch 16 is associated with the rocket arms 11, 13, and when an electromagnet 19 is energized the latch disengages arm 13 so that the feed roller 1 is driven by the arm 11 to advance the foil in steps of a length determined by the adjustment of chain 15. When the electromagnet 19 is energized, the latch 16 engages the arm 13 which then moves in unison with the arm 11, the sprocket 6 driven by the arm 13 overtaking the sprocket 5 and thus producing a longer advance of the foil. Control of the electromagnet 19 is effected by a counter mechanism which may be adjusted to the desired cycle of operation (Figs. 4 and 5, not shown). In another embodiment (Figs. 8 and 9, not shown), the sprockets 5, 6 are chain-driven from a single oscillating element and control of the feeding cycle is effected through a clutch which is associated with the sprocket 6 and which is responsive to the output from the counter mechanism.

Abstract: 1,193,728. Dishwashing machines. INVENTOR A.G. 8 Nov., 1968 [10 Nov., 1967], No. 52939/68. Heading A4F. [Also in Division D1] An automatic dishwashing machine (or other automatic washing machine) comprises a circulating pump having a sump enclosed by the pump housing 7 and having a water inlet pipe 15 connectable to a mains water supply pipe 13 via a valve 14 controlled by means responsive to the water level within the washing space of the machine. In operation, on closure of a programme-controlled switch 19 the electrically actuated valve 14 is opened and water is admitted to the washing space through the pipe 15, the pump housing 7, and a conduit 11. When a predetermined water level in the washing space is reached a changeover switch in a housing 18 is actuated to close the valve 14, and to energize the pump motor 8 and a heating element 26 controlled by a thermostat 25. The pump when operating draws water from the washing space via the pipe 11 and passes it through a conduit 12 and a spray pipe (not shown) for discharge over the articles to be washed. An arrangement of vents is provided for the outflow of steam from and fresh air into the washing space to facilitate drying of the washed articles.

Title: Lamp control means
IPC: G03B27/30
Filed: 1965-12-14
Abstract: 1,110,077. Thermographic contact printing. VIEWLEX Inc. Dec.14, 1965 [May 4, 1965 to No.52987/65. Heading G2A. Original and copy sheets are passed together between rollers 1 and 2, roller 2 being a glass cylinder within which is a heat lamp 3 focused by a reflector on to the line of contact between the rollers. On the shaft 4 of roller 1 is a cam 5, which, as it rotates, engages against the central blade 6 of a switch 7, causing it to touch alternately one contact (8) and then the other (9) of the switch Fig. 2 (not shown). When contact (6, 8) is closed, a capacitor (10) is charged up from a power source. On breaking this contact and closing the other contact (6, 9), a solenoid (14) is energized, closing a relay contact (15) and so connecting the lamp to the mains supply. The lamp is now energized, and remains on for a period slightly greater than one complete rotation of the rollers, this period being determined by the values of the capacitor (13) and the solenoid. Thus before the lamp is de-energized again, switch 7 has operated to charge up the capacitor (13) once more, and so the lamp remains on. If for any reason the rollers stop rotating, capacitor (13) is not re-charged once it has lost its charge, so that relay (15) is also de-energized and the lamp circuit is broken. Thus if the rollers stop, the lamp is automatically switched off, so preventing damage to the stationary rollers and sheets by overheating.

Title: Method and apparatus for the treatment of surface layers by irradiation with charge carrier beams
Inventor: STEIGERWALD KARL-HEINZ
IPC: B05D3/06
Filed: 1969-11-06
Abstract: 1284784 Coating apparatus K H STEIGERWALD 6 Nov 1969 [13 Nov 1968] 54388/69 Heading B2L [Also in Division H1] In an electron beam irradiation apparatus for setting varnish or curing paint the work is placed in a work chamber evacuated to a reduced pressure and communicating with an electron beam generator through apertures which do not obstruct the beam, and deflecting means are provided for deflecting the beam successively round at least part of a circumference of the work. In Fig. 4 the beam generator 105 communicates with the cylindrical work chamber 101 via an apertured diaphragm 110 and both chambers are separately pumped. Magnetic deflection means such as 116 are disposed at 30 intervals around the circumference of the chamber 101 and are energised in sequence to scan the beam round the circumference of the work 104. The energisation may be controlled by a magnetic tape (Fig. 3, not shown) which may also control the beam energy to take account of the varying angle of incidence of the beam. In Fig. 4 the work chamber is divided into an outer chamber 146 containing the deflecting means and an inner irradiation chamber 147 by means of partitions 144 and 145. These may be insulated from each other and used as deflection plates to produce a transverse deflection, or they may support electromagnets (Fig. 5, not shown) or radially magnetised per- 7 manent magnets (Fig. 6 not shown) which deflect or defocus the beam to widen the irradiated area. The work 104 is mounted on a pair of rails and pulled through the apparatus by a cable 161 driven by a motor 164. The apparatus may include a glow discharge electrode 165 and an electrostatic varnish application device 168. In a first passage through the apparatus the work is cleaned successively by a glow discharge from electrode 165 and by electron irradiation, and is then coated with varnish; the work is then passed again through the electron beam which cures the varnish. In a modification (Fig. 1 not shown) the partitions 144 and 145 are omitted and the deflecting means are disposed wholly within the work chamber. A plurality of beam generators may be disposed around the circumference of the work chamber. The beam energy should be less than 100 kV and the beam may contain two or more components of different energies; the beam may be pulsed, and may be controlled so that a varnish layer has a hard outer surface whilst the layer remains slightly resilient.

Signals received by a transponder are detected at 2 and supplied via an amplifier 3 to trigger a pulse generator 4 which produces either a single pulse of predetermined duration or a coded sequence of identifying pulses. The output of generator 4 starts an oscillator 5 whose output frequency is swept over a frequency band by a sweep generator 11. Signals from the oscillator 5 are amplified at 6 frequency-multiplied at 7 and transmitted via a harmonic-suppressing filter 8 to an aerial 9a. A monitor 10 consisting of two resonant cavities with co-operating diodes is coupled to the waveguide 9 and provides signals at the upper and lower limits of the swept frequency band, one signal initiating the sweep of generator 11 and the other initiating the flyback. The system may be tested by a generator 13 which is substituted for the generator 4. The signals from the monitor 10 operate a bi-stable device, Fig. 3 (not shown), controlling the charge and discharge of a capacitor to produce the sweep voltage which controls the capacitance of a diode in the circuit of the oscillator 5, Fig. 5 (not shown).

Abstract: 1379936 Seaming non-metallic sheet material AMERICAN CAN CO 15 Dec 1972 [30 Dec 1971] 57963/72 Heading B5K A plastics end member 15 is welded to an unstepped tubular plastics body 17, e.g. to form a squeeze tube, by positioning the member 15 within the body 17 and irradiating the area to be welded with a laser beam 21 while simultaneously imparting relative rotational motion between the beam and the area to be welded. Preferably, the member 15 and the body 17 are made of polyethylene and the tube may be cylindrical or of oval section. The member 15 is formed with a shoulder 14 and a skirt 13 the outer diameter of which is greater than the inner diameter of the body 17 to produce an interference fit. A raised ridge 11 may be formed on the skirt 13 to provide additional material in the weld area. The body 17 and the member 15 are assembled on a rotating mandrel 16 and positioned so that the area to be welded is near the focus of a lens 19 which intercepts the laser beam 21. A heat conductive roller 23, e.g. of aluminium, removes heat from and smooths the surface of the weld. Preferably, the laser beam is a carbon dioxide gas laser having a wavelength of 10À6 microns and a power in the range of 100 to 200 watts. The surface of the mandrel 16 may be polished to reflect any energy, which has travelled through the material, back through the material. In a modification, the circular beam spot pattern may be elongated so that its dimension along the weld path is increased while the width remains constant. This may be accomplished by cylindrical lenses, mirrors or by utilization of off-axis astigmatism. The plastics workpieces may contain metal layers.
