Filed: 1953-04-30
Abstract: 786,263. Signs. COMPRA PLASTICS, Ltd., and STURM, R. H. April 29, 1954 [April 30. 1953], No. 11962/53. Class 3(2) [Also in Group XL(a)] A sign. which is directionally reflecting and can exhibit daylight fluorescence, comprises a support 1, a reflecting coating 2, a coating 3 including a luminescent material, and a layer of small approximately spherical particles 4 of ultra-violet absorbent material, e.g. glass, closely covering and adhering to the luminescent material coating whereby the particles 4 serve as an ultra-violet filter to light incident on the luminescent material. The support 1 can be composed of a thermoplastic material such as polystyrene, polyvinyl chloride, vinyl copolymers, acrylic polymers or copolymers, or of a porous material such as paper, cardboard, wood, felt. leather or a textile material coated or impregnated with the thermoplastic material. The reflecting coating 2 can be of the type described in Specification 669,738 [Group IV(a)] or Specification 774,891 [Group IV(a)] by pigmenting the coating media described therein with white materials such as magnesium carbonate, titanium dioxide and/or zinc oxide. The coating is applied in liquid form, and then dried or polymerized. The luminescent coating 3 is formed of the same type of material as the reflecting coating with luminescent materials examples of which are given. The luminescent materials may be chosen to have a luminescent colour approximately to the visual colour of the coating. The layer of glass particles 4 is preferably one particle thick, packed closely and applied before the luminescent coating has dried or polymerized. The glass particles can be made from glass containing 2.0 to 3.5 per cent lead oxide and of a diameter of 0.40 mms. The glass particles can be coloured with other metallic oxides such as chromium, copper and uranium oxide. The luminescent coating 3 is covered with a transparent layer 5 of composition of the type described in Specifications 669,738 and 774,891 which seals the coating 3 against moisture.

Title: Device for the production of apertured moulded blocks and the like
IPC: B27J5/00
Filed: 1935-04-18
Abstract: 443,276. Moulding cork composition blocks. HONEGGER, H., 66, Rainstrasse, and GREUTERT, M., 24, Klosbachatrasse, both in Zurich, Switzerland. April 18, 1935, No. 12034. [Class 87 (ii)] Longitudinally apertured blocks or slabs of granulated cork and a binder are moulded in a box provided with cores slidably mounted in the walls of the box, and with one or more pressing plates. In the form shown in Fig. 1, cores 5 are passed through apertures in a removable bottom 4 supported by bars 9 in a two-part box 1, 2 held together by clamps 3. The cores are spaced at their upper ends, while the box is being filled, by a frame provided with caps to close the ends of the cores. A perforated plate 8 is then passed over the cores and is forced to compress the cork composition around the cores. The plate is then held by rods 9 until the composition has set. In a modification, the mould has a body portion 10, Fig. 5, and apertured ends 14 for supporting the cores 16, while the top 11 is held by clamps 13 and wedges 12. The ends are forced inwardly and secured by rods 17. The top 11 may be forced downwardly by the wedges 12 or by pressure means. In another modification the cores are movable in slots in the ends of the box. In some cases, the slots are provided with movable plates to prevent loss of material. In another form, the ends of the cores are supported by plates movable vertically in the end walls of the box, and are locked in position until the pressure of the cork composition above the cores effects their release. In some cases, the downward motion of the top of the box effects the release of the cores. In each case, when the cores are released, they descend further and compress the composition beneath. In the form shown in Fig. 7, the box comprises a body portion with apertured ends for the cores 19 and top and bottom pressing plates held by rods 22. In another form, the bottom of the box is reinforced by girders and provided with spring-controlled rollers for transportation purposes. When the pressure is removed from the top of the box, the springs cause the mould box to be supported on the rollers. In some cases,. the rollers are carried by spring- controlled arms. In another form, Figs. 17-19 (not shown), the box has detachable sides, ends, and top, and is held in an outer reinforcing casing.

Abstract: 359,471. Sound-reproducing apparatus associated with kinematographs. SOC. DES ETABLISSEMENTS GAUMONT, 57, Rue St-Roch, Paris. April 16, 1930, No. 12085. Convention date, May 14, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] The speed of a kinematograph is adjusted to be in synchronism with that of a phonograph by means of a regulator actuated by a differential mechanism. The kinematograph 1 and phonograph 4, Fig. 1, are driven by electric motors, 3, 6 respectively and the pinions 8, 9 of the differential gear 7 are geared to the kinematograph and phonograph respectively. The frame 10 of the differential 7 actuates an arm 14 secured on an angle 13 and carrying an insulated brush segment 15 which moves over conducting insulated plates 16, 17. A resistance 25, connected with the plates 16, 17, is either short-circuited or put in circuit by movement of the segment 15. The terminals 20, 21 are connected to the electric supply and the closing of a switch 22 causes the starting of the motors 3, 6. When the pinions 8, 9 are revolving with equal speeds the frame of the differential 7 remains at rest, but if the kinematograph speed is greater than that of the phonograph the frame will revolve to displace the arm 14 carrying the brush segment 15 and insert the resistance 25 in circuit to retard the motor 3. The further resultant movement of the arm 14 will cause the resistance 25 to be short-circuited again to accelerate the motor 3. In this way synchronism between the motors 3, 6 is preserved within certain limits. Another arrangement of the switching means is shown by Fig. 2, in which 25a is the adjustable resistance and the arm 14a carries brushes 31, 32, 33 which move over contacts 34, 35, 36 respectively. The contacts 35, 36 are each in two portions 35, 35b and 36, 36b, respectively, insulated by gaps 35a, 36a. In this way, the arm 14a. may short-circuit the whole of the resistance 25a, the portion 40 to 38 only, or put the whole resistance 25a in circuit according to the displacement of the arm from left to right over the contacts.
