Patent GB-2179888-A (GB)
Title: Variable speed form-fill-seal machines
Inventor: MUGNAI GEORGIO
IPC: B65B51/30
Filed: 1985-09-04
Abstract: A horizontal form-fill-seal machine has counter-rotating sealing jaws 5 and 6 whose progress is monitored by photocells PC1 and PC2 such that once the jaw 6 passes photocell PC1 the speed of the motor driving the sealing jaws is lowered to provide increased dwell time to achieve adequate seal strength without the need for high sealing temperatures, and the speed is then increased once the jaw 6 passes photocell PC2 and enters the "rest phase" before the next sealing operation. The motor speed control is such that despite varying machine throughput speeds, the dwell time of the film between the jaws 5 and 6 at the sealing station is substantially constant to provide for optimum seal strength at the optimum sealing temperature of the film being used. <IMAGE>

Title: Sonic range and bearing finder
Inventor: HODGES ROBERT JAMES
IPC: G01S11/14
Filed: 1985-09-26
Abstract: A sonic range-finder uses as its responsive elements a ring of outwardly-facing microphones (a, b, c), which respond to sound from a target (1). If the range-finder is active it has a transmitter (2), which emits ultrasonic pulses at, for instance, one per half-second, in broadcast manner. The pulses reflected from the target are detected by two or more microphones and the relative responses indicate the range and direction of the target. If the range-finder is passive, operation is the same, except that it relies on sound from the target. The microphone array is a small (e.g. 60 cm in diameter) circular array of outwardly facing electret microphones stretched onto a printed circuit band and secured to a cylindrical member. <IMAGE>

Patent GB-873655-A (GB)
Abstract: 873,655. Indicating-apparatus. WESTERN ELECTRIC CORPORATION. Sept. 7, 1959 [Sept. 18, 1958 (2)], No. 30420/59. Class 106 (4). [Also in Group XXXVI] In an arrangement wherein a rotor rotates about an axis relative to a stator and the rotor is supported for axial rotation by two axially aligned filaments each secured to the rotor and the stator, the filaments are maintained in tension, and an anchor of softer material than the filament wherein the filament will tend to seat, is provided in at least one of the securing means for each filament. The mounting arrangement is shown applied to a centre pole moving coil meter which includes the following features: (1) Damping by grease around the filaments. (2) The magnetic field adjustment by movable iron inserts in the two magnetic loops. (3) The provision of a shaped liner, Fig. 3 (not shown), on the inner face of the magnet to give a desired flux distribution. (4) The provision of a section of coil former which is not in contact with the coil and may be cut away to reduce induction damping when not desired. (5) Protection against physical shock. (6) Zero adjustment. Coil 4. Fig. 2, which is movable in air gap 47 about the meter axis is inserted through a passage 37 in the inner polepiece 31, the passage being subsequently plugged with a plug 41 of soft magnetic steel. Magnetic balance in the two circuits shown is achieved by adjustment of tapered cores 59, 75 in holes 55, 57 by means of screws 61, 77, the heads of which are located axially so that the cores may be raised or lowered. The cutting of the holes may produce saturation across the neck. The shaped liner 49 which has varying length parallel to the axis and which gives the desired flux distribution in the gap, may be rolled and cemented to the inside face of the magnet 45. The laminations which comprise the magnetic circuit are secured by screws passing through two rings, the rings surrounding the laminations and extending across the top and bottom to provide platforms 13, 15, Fig. 7, whereby the torsional suspension can be secured to the stator. The bar 117 carrying the coil assembly 4 is turned over at its ends, and has a stepped tower 123 secured thereto in which is arranged a disc 145 of soft sheet brass having a central portion 167, Fig. 8, turned up to form a seat or fulcrum for the filament 161, 163. The filaments which should have a twistable length in inches less than the range of deflection in degree divided by 300, may be of a nickel platinum alloy having a width to thickness ratio of seven-to-one, fifteen-to-one, and may be heattreated to relieve strain. The upper outer end of filament 161 is turned over a rounded ribbedend portion 198b of a spring 183 and secured, as by soldering, to a platform 199. The spring 183 is seated on a flange 175 of a hollow screw 173, insulated from the bridge 13 by a disc 113. The tower 123 in projecting into the screw hollow prevents excessive movement in a transverse direction as a result of physical shock. Zero adjustment is effected by a rotating spring 183 around screw 173. Alternative springs 4 are referred to, and a number of dimensions are given.
