Title: Improvements in or relating to coating glass beads for reflex reflectors
IPC: G02B5/128
Filed: 1957-10-02
Abstract: Small transparent glass beads are coated by forming them into a slurry with an aqueous solution of a silicate, atomizing the slurry to form particles consisting of a glass bead coated with the solution, and at least partially drying the particles while they are free falling.  Atomization may be effected by forcing the slurry through a nozzle under pressure, using auxiliary air jets to break it up into droplets.  The particles are then collected, preferably treated with an aqueous solution of an acid substance to remove most of the alkali portion from the silicate, when an alkali silicate has been used, and heated at an elevated temperature above the boiling point of water to dry and rigidify the coating.  The coating has a refractive index of from 1.45 to 1.5 and may be used as a space coating for glass beads of higher refractive index, e.g. above 1.7, to form spherical lenses of still higher effective refractive index for use in reflex reflective coatings.  In an example, glass beads of refractive index 2.49, analyzing 67.5% lead oxide and 32.5% titanium dioxide, are coated to give composite elements of effective refractive index about 2.9.  The coating may be coloured by adding a suitable transparent colouring material to the silicate solution. The coating process may be repeated to give the desired thickness. The bead cores may have a partial, e.g. hemispherical coating of a reflective material, e.g. aluminium; or the core may be coated with a silica-containing layer, as described, then hemispherically coated with a reflective material, and additionally coated with silica.  The coated beads may be used in liquid paint or lacquer finishes, or they may be bonded in a layer having dispersed therethrough a reflective pigment such at titanium dioxide; the outer surface may be coated with a thin transparent protective layer to give a lenticular surface.  Or, hemispherically silvered beads may be used partially embedded in a clear or coloured layer.  A smooth surfaced structure may comprise a binder layer in which a reflective pigment is dispersed and in which the backs of a layer of coated beads are bonded.  A colour layer may surround the beads without overlying them, and this layer and the fronts of the beads may be covered by a smoothsurfaced transparent protective layer; this and the binder layer may be of N-butyl methacrylate polymer resin or mixtures thereof with other resins. By using different colours in the binder layer, the colour layer and the coating of the beads, colour effects which vary with the lighting may be obtained.  Fabrics and other surfaces may be coated with a binder, and the reflective beads pressed into this.

Title: Improvements in or relating to cigarette packing machinery
IPC: B65B19/02
Filed: 1925-12-08
Abstract: 266,834. Molins, W. E. Dec. 8, 1925. Apparatus for setting-up collapsed boxes. In a machine for assembling the slide and shell of a slide and shell box, collapsed shells are fed singly from a pile to a suction element adapted to draw upon the broad underside of the shell and maintain it in a fixed position on the bed of the machine whilst a movable element engages one remaining side of the shell and opens it out completely, independently of an auxiliary abutment on or near the bed of the machine. A slide 20, filled with cigarettes bv the apparatus described in Specification 13956/15, [Class 94 (i), Packing &c.]. has its ends folded over as described in Specification 169,341 whilst it is moved by a conveyer 1 to the shell feeding and opening mechanism. The lowermost shell of a pile is fed by a reciprocating table beneath continuously rotating rollers and a knurled sector 29. Rotating with the sector is a cam 32 adapted to press a finger 30 into engagement with the shell to check the progress of one side of it and deliver it above a suction member 34 at an angle to the conveyer 1. The member 34 grips the lower face of the shell whilst an upper suction member 36 is moved upwardly to open it out. The support 43 of the suction member 36 is carried by parallel links 44, 42, the latter of which is secured to a spring-pressed rocking arm 39 actuated through a bell-crank lever 37 by the main shaft of the machine. The oing action is limited by a stop 46 on the member 36. the stop pressing on the corners of the shell nearest the conveyer to keep the base of the shell flush with the table. This, in conjunction with a bowing of the top of the shell caused by the suction member 36, facilitates the entry of the slide into the shell. The movement of the rocking arm 39 is continued after the release of the suction member from the shell so that the arm 43, through the engagement of a stud 43<a> on it with a fixed stud 43b, may be lifted out of the path of the shell and slide, the arm being resiliently mounted on the link 42 to adapt it to pivot about the link 44 for this purpose. In a modification, the upper suction element is replaced by a hooked member whichraises the upper part of the collapsed shell.

Abstract: 539,321. Radio navigation. SPERRY GYROSCOPE CO., Inc. Dec. 1, 1939, No. 31291. Convention date, Dec. 9, 1938. [Class 40 (v)] [Also in Group XXXVIII] A radio position-indicating system for aircraft comprises a radio receiver automatically tuned in succession to a number of transmitters and means for indicating the bearings of the transmitters. As shown a directional antenna 5 co-operating with a non-directional antenna 9 automatically sets itself at right angles to the direction of the incoming waves as described in Specification 523,953. The shaft of the movable antenna is coupled to the transmitter 11 of a selsyn system which co-operates with another transmitter 11<SP>1</SP> driven by a gyro or other compass so that the position signalled to the receiver indicates absolute true or magnetic bearings (instead of bearings relative to the fore and aft line of the craft). A slowly driven commutator 50 energizes in turn three previously selected brushes of a group 37..42 co-operating in known manner with a gapped ring for automatic tuning. Coupled to the commutator 50 is a further commutator 76 .. 78 which connects receiving selsyns 65, 68, 69 to the transmitter 11<SP>1</SP> in turn. These selsyns which are provided with means for adjusting the stators in relation to their bases to correct for magnetic variation if necessary are provided with an axial hole with cross wires to enable them to be placed accurately on the representations of the corresponding transmitting stations on the map. The rotors carry pointers or control light beams to indicate the bearings and so give a fix by their intersection. The readings of the compass and the directional antenna can be combined by mechanical instead of electrical means. Specification 366,764, [Group XX], also is referred to. The Specification as open to inspection under Sect. 91 (4) comprises also an arrangement in which the aircraft is supposed to follow a beam so that it is sufficient to give a continuous indication of the bearing of a single other station, the intersection of the bearing and the beam giving the craft's position. This subject-matter does not appear in the Specification as accepted but is included in divided Specification 539,475.

Filed: 1919-12-16
Abstract: 159,374. British Thomson - Houston Co., Ltd., (General Electric Co.). Dec. 16, 1919. Exciting.-A commutating machine with a falling volt-ampere load characteristic, for example for arc welding, has two sets of poles, one set 6, Fig. 1, saturated and the other 7 unsaturated, and an auxiliary brush 4 between the main brushes 3, 13. The component AD of the armature reaction AR produces little effect on the poles 6 which give constant volts at the brushes 3, 4, to which the shunt coils 8 are connected. The component AE gives between the brushes 4, 13 a voltage which increases with the load current and is opposed between the brushes 3, 13 to that given by the brushes 3, 4. Thus, the load volts fall with increasing current. An adjustable number of series windings may be wound on the poles 7 to aid the armature flux AE or, alternatively, these poles may have windings in series with the coils 8 across the constantvoltage brushes 3, 4 and so wound as to oppose the flux AE so that at no load the volts between the brushes 4, 13 are added to those between the brushes 3, 4 but are decreased as the armature reaction increases. Fig. 4 shows a machine having both shunt and series coils 9, 10 of this nature differentially combined. By adjusting them so that at about half load the resultant flux in the poles 7 is zero, a decreasing voltage between brushes 4, 13 is added to that between brushes 3, 4 up to half load, whereafter an increasing voltage between brushes 4, 13 is subtracted from that between brushes 3, 4. Commutating-poles with ordinary series windings may be added.
