Abstract: 1315522 Reflective coated sheet materials MINNESOTA MINING & MFG CO 26 March 1970 [28 March 1969] 14897/70 Heading B2E [Also in Division B5] A highly flexible, reflex reflective construction comprises a layer of reflex reflecting transparent spheres in a binder and a continuous overlying transparent solid top coat having a flat front face, said binder being a transparent elastomeric composition having a refractive index sufficiently low that the ratio of the refractive index of the transparent spheres to that of the binder is in the range of 1.85 to 2, the refractive index of said transparent spheres being at least 2.4, said top coat being a transparent elastomeric composition having a Shore A hardness above 40, both said top coat and said binder having a tensile strength at break of at least 200 psi at 75F. and a glass transition temperature below 10C, the maximum strain at break of the topcoat being attained at a temperature not more than 30C higher than the maximum strain at break of the bead binder. The binder may be coloured and may be a copolymer of vinylidene fluoride and perfluoropropene, tetrafluoroethylene, 3-hydroxyperfluoropropene or a mixture thereof. The top coating elastomer may be a polyurethane or an epoxy amine elastomer. The term sphere is used in the broad sense to include substantially spherical elements and beads. The spheres may be of glass and are preferably partially coated with a metal, e.g. aluminium; alternatively, the spheres may have specularly reflecting material, e.g. aluminium flakes adjacent the surfaces thereof opposite the top coat. The constructions of the invention may be applied to substrates, e.g. cloth, non-woven fabric, leather or paper. In the examples, the top coat is cast on a releasable substrate comprising polyethylene coated paper and dried, a coating of the binder is cast on the top coat, dried, coated with glass spheres and the assembly consolidated between a heated metal cam and a rubber roller. A reflex reflective aluminium coating is then applied to the spheres by vapour deposition, covered by an adhesive coating which is dried prior to the application thereto of a polyethylene film as a protective liner. In use, the liner is removed, the adhesive coated surface of the resultant construction laminated to a cloth substrate and the releasable substrate removed.

Filed: 1921-06-02
Abstract: 185,496. Preston, L. G., Airey, H. Morris-, and Shearing, G. June 2, 1921. Thermionic oscillation generators and modulating systems.-Relates to valve transmitting- circuits in which the high-tension supply is fed fiom a pair of rectifying-valves V2, V<3> through a smoothing-condenser S to the plate of the power valve V<1>, and consists in an arrangement of signalling-means so designed as to protect the rectifying-valves and the smoothing-condensers from the effects of excessive potential arising when the high-tension input greatly exceeds the radiation output. As shown in Fig. 3, switches Q. R are inserted in the leads from the hightension transformer T to the plates of the rectifying-valves V<2>. V'. A key K in the grid circuit of the grid-leak control valve F governs the emissions from the main power valve V<1> to the aerial. A master signalling-key K<2> is so arranged that its rocking arm normally rests on contact a when the keys Q, R and K are open. When, in signalling, contact a is broken and contact b is made, the keys Q, R close a very small fraction of a second earlier than the grid key K; and conversely when contact a is closed, then the key K is operated slightly ahead of the keys Q, R, This small interval of time is sufficient to prevent the valves V<2>,V<3> from flashing-over from excessive voltage. Fig. 5 shows a similar signalling-arrangement applied to two power valves V<1>, V' feeding the aerial in series. The gridleak control valves F<1>, F<2> are coupled by coils L<3>, L' and are energized from a separate source of continuous oscillations L<2>, C<2>, which takes the place of the retroactive coupling E shown in Fig. 3.

Title: Control system for, and a method of, controlling a plurality of direct current motors
Inventor: MYLES ASA HERBERT
IPC: B66C13/30
Filed: 1956-05-22
Abstract: 788,042. Control of several D.C. motors. SQUARE D CO. May 22, 1956, No. 15701/56. Class 38 (3). Stability during plugging operation is afforded by cross-connecting the series field windings of mechanically coupled D.C. motors 10 and 11. The motors are initially accelerated from rest in the forward direction by moving master switch 29 to close contacts 32, 36, whereupon contactors 17, 18, are energized and the armature 10a is connected in series with resistor 24 and field winding 11f whilst the armature 11a is placed in series with resistor 25 and field winding 10f, these two branch circuits being series-connected with a common accelerating resistor 16. Movement of the master switch to its second position operates relay 26 so that each series field winding is directly connected to its own armature and the resistors 24, 25 are removed from circuit. When the master switch is moved through the third and fourth positions and into the fifth position, contactors 21, 22, 23 are operated in sequence to short-circuit sections of the resistor 16 in steps, causing the motors to accelerate to full speed. The motors may be started from rest and accelerated in the reverse direction by appropriate movement of the master switch, the contactor 19 being operated instead of the contactor 18. Assuming that the motors are operating with the master switch in any reverse position other than the first, movement of the switch to the " off " position causes contactors 17, 19, 26 to be de-energized as well as any of the contactors 21, 22, 23, which may have been previously operated. Adjustment of the master switch to the forward positions for reverse-current braking operation recloses contactor 17 and closes contactor 18, and, if the motor speed is above a low value, the voltagedrop across resistor 24 is sufficient to cause relay 28 to open its contacts 28a. This prevents operation of the contactor 26 so that the whole of the resistor 16 remains in circuit. Furthermore, the resistors 24, 25, are included in circuit and the field windings 10f, 11f remain crossconnected until the speed drops to a low value and the relay 28 is released. The system may be modified for use with four driving motors Fig. 2 (not shown).

Title: Improvements in telephone apparatus
Inventor: RHODES JOHN GEORGE LAYCOCK
IPC: H04M1/31
Filed: 1962-04-25
Abstract: 1,048,251. Pulse sending equipment. SHIPTON ELECTRONICS Ltd. July 22, 1963 [April 25, 1962], No. 15750/62. Heading H4K. Telephone dialling pulse sender includes a pulse generator and a counter which, upon counting the number of pulses representing a digit of a multi-digit number set up for sending, operates a pause circuit to stop the generator for an interdigital pause period during which the counter is reset to zero and its output circuits set up for the succeeding digit. The Figure shows a loud-speaking telephone circuit equipped with the pulse sender according to the invention. In order to set up a call a key such as K1, of which there is one for each line in the system, is operated. Key K1 has three digit contacts B, C and D, corresponding to the respective digits of the number required, and an A contact which, when closed, operates a relay 13 to loop the exchange line to indicate a calling condition, and also applies H.T. to the various circuits of the apparatus. Dialling tone from the line is applied to a dial tone detector circuit 5 and causes normally conducting transistor Tr 5  to be cut off to allow capacitor C14 to charge. After two seconds of dialling tone the voltage on C14 is such as to trigger the dial trip circuit 6 which, via gate 17, cuts off transistor Tr8 and allows the dial pulse generator 7 to operate and, via relay 16, send dialling pulses to the line. Dialling pulses are also applied, via line 21, to the counter 10 which steps on until the number of pulses counted is such as to energize one of the coincidence lines 10b which is connected to contact B of the selected switch K1. When this line is energized the pause circuit is operated, over line 23, and this, via gate 19, allows transistor Tr8 to conduct to inhibit the dial pulses. The pause circuit also, via line 25, resets counter 10 to its initial condition and applies a stepping pulse to the sequence counter 11 which inhibits the action of the counter output connected to contact B of switch K1 and enables the counter output connected to contact C of switch K1. At the end of the pause period the dial pulse generator 7 is enabled via gate 18 and the pulses corresponding to the second digit of the required number are counted out as for the first digit, the action is then repeated to enable the third digit, selected by contact D of switch K1, to be dialled out, at the end of which the pause circuit, in resetting sequence counter 11, causes the final circuit 9 to be triggered, to remove a masking condition from the line, to remove H.T. from one side of all bi-stable circuits so that when switched on again they will reset to their initial condition, and to apply H.T. to the send and receive amplifiers to allow the subscriber to talk to the called party.
