The surface may be of cellulose acetate the treatment being effected with acetone vapour for a time just sufficient to liquefy the master surface. The process is also applicable to the manufacture of masters for reflective signs for traffic control and for refractive lighting fixtures (e.g. used in street and home lighting). The master can be fabricated by the method of Specification 1,421,139. The groove width is typically 0À002 inch. After the saturated acetone vapour treatment side walls are attached to the periphery of the master and a silicone rubber with catalyst is poured in. After curing the silicone rubber negative matrix is separated and used to cast positive projection screens, which may then be aluminium plated.

Abstract: 661,718. Wood-shaping machine. MARTENSSON, M. May 30, 1949 [May 29, 1948], No. 14456/49. Class 145 (i). In a wood shaping machine in which a work supporting table is provided with an opening for the cutter spindle a screw spindle carried by the frame and engaging the work table serves by means of a hand wheel to move the work table horizontally in relation to the cutter spindle for accurate cutting depth and size of the work piece. As shown a work table 4 is slidably mounted on a fixed frame 1, 2 and is adjustable by means of a screw spindle 6 by a 'hand wheel 7 operating with a scale 8. The work table 4 is provided with an opening for the cutter spindle 9 and within the opening is fitted a guide collar 14 which itself is provided with an oval opening 15 surrounding the cutter spindle. Forming part of and joined to the guide collar by a part 17 is a guide member 18 which comprises two spring bows. These are connected to the frame in such a manner that as the work table is adjusted to another position the guide member 18 automatically is adjusted relatively to the cutter. As shown a slide 20 is engaged by its pin 21 with the frame and as the table 4 is adjusted to a new position links 23 move the ends of circular links 25 which are pivoted together and to the guide collar at 26. Movement of the circular links 25 operates, through links 29 and pin and slot arrangements 27, 28, the guide member 18 which partially surrounds the cutter. The work piece 31 is locked on the pattern 34 which during the cutting, operation is pressed against the guide collar 14. A recess 33 is formed on the guiding member 118 to act as a splinter groove to prevent splinters entering between the pattern 34 and the guide member 18. In a modification the guide collar 14 is replaced by a supplementary disc.

IPC: H03F3/48
Filed: 1924-06-18
Abstract: 243,039. Taggart, J. Scott-. June 18, 1924. Thermionic amplifiers and detectors.-In wireless receivers of the dual amplification or reflex type, the low-frequency currents are fed back by means of a resistance coupling. A tuned circuit L1, C1 is connected between the aerial A and earth E in series with the plate battery B2 and a resistance R5, of the order of 70,000 ohms., shunted by a condenser C2. The amplifier VI has its grid connected to the aerial A through a condenser C3, and its positive filament terminal earthed, a grid leak R3 being connected between the grid and the negative terminal of the filament battery B1. The plate coil L2 transfers the highfrequency output to the tuned grid circuit of a detector valve V2 fitted with the usual grid leak R4 and condenser C5. The high-frequency output coil L4 of the valve V2 reacts on the aerial coil L1, and the low-frequency output is fed by the resistance R5 into the grid circuit of the valve VI. The low-frequency output of the valve V1 is utilized in the telephones T, or is fed by resistance or transformer coupling to the grid of a third valve functioning as a low-frequency amplifier. The rectifying valve V2 mav be replaced by a crystal or other detector. A tunedanode coupling may replace the transformer coupling L2, L3, and the telephones T (or the low-frequency coupling to the third valve) may be located between the plate of the valve VI and the tuned anode circuit. Reaction may be provided between the plate circuit of the valve V2 and the plate coil of the valve V1; or between the plate circuit of the valve VI and the aerial.

Title: Improvements in or relating to the colouration of cellulose ester or ether materials
Filed: 1931-05-19
Abstract: Vat dyes, dyeing with; cellulose esters or ethers, dyeing; printing; dye preparations; indigoid and thioindigoid dyes; leuco compounds of vat dyes, derivatives of.--Materials made of or containing cellulose esters or ethers are coloured by applying thereto or forming thereon substantially water-insoluble metal derivatives of the leuco compounds of vat dyes.  Specified metals are zinc, cadmium, aluminium, tin, lead, and iron.  The metal derivatives may be prepared in substance by reaction of the alkali metal salts of the leuco compounds with the appropriate metal salts, and dispersions suitable for use in dyeing or printing may be obtained by performing the reaction in presence of dispersing agents and/or protective colloids, e.g. sulphonated castor oil, sulphoaromatic fatty acids such as sulphonaphthalene ricinoleic acid (cf. Specifications 242,393 and 273,819, [both in Class 2 (iii), Dyes &c.]), oleyldiethylethylenediamine, starches, gums, glue or gelatin. Alternatively, the metal derivatives may be formed on the material by applying a mixture of the unreduced vat dyestuff, a reducing agent and an oxide, carbonate or other compound of the appropriate metal and steaming.  The invention is particularly applicable to the production of coloured discharge effects with discharge preparations comprising reducing agents such as zinc formaldehyde sulphoxylate coloured with vat dyestuffs.  Any vat dyestuffs having affinity for cellulose ester or ether materials and especially those used in the processes of Specifications 374,839 and 374,884, may be applied as metal derivatives according to the invention.  The metal derivatives may be applied in conjunction with swelling agents for the materials to be coloured, e.g. ethyl alcohol or phenols such as hydroquinone. The following examples are specified.  (1) A cellulose acetate material or a cellulose acetate and silk mixed material is printed with an aqueous paste containing Ciba yellow G or Ciba scarlet G, methylated spirit, gum arabic, zinc carbonate and zinc formaldehyde sulphoxylate, dried, aged, chromed, washed, soaped, and again washed and dried.  (2) A cellulose acetate fabric dyed with a dischargeable colour is printed with an aqueous paste containing the zinc salt of lenco-Ciba yellow G, Ciba scarlet G, Durindone red Y, Algol violet BBN, Indigo LL, Indigo LL/2R or Caledon jade green, methylated spirit, gum arabic and zinc formaldehyde sulphoxylate, aged, chromed, washed, soaped, rinsed and dried.  The zinc salt is prepared by adding a solution of zinc chloride to a solution containing the dyestuff, caustic soda and sodium hydrosulphite, and filtering off and washing the precipitate.

Title: Improvements in or relating to submersible beacon
Inventor: FARMAN ROBERT
IPC: G01S1/72
Filed: 1967-03-31
Abstract: 1,212,507. Acoustic beacon systems. PLESSEY CO. Ltd. 25 March, 1968 [31 March, 1967], No. 14868/67. Heading H4D. A submersible beacon generates at least two acoustic signals of different frequency; the lower or lowest frequency signal can be detected to give an approximate indication of beacon position and the higher or highest frequency signal can be detected to give a more precise indication. In the embodiment illustrated the beacon 1 has two transducers 1A, 1B which respectively transmit upwardly a broad 10 to 20 kHz beam and a narrow 50 to 400 kHz beam. Attenuation of the high frequency beam by the water reduces the risk of false homing on spurious signals reflected from the water surface and re-reflected to the surface from the water bottom. The different frequencies may be transmitted on a time-sharing basis. The beacon is moored to a lead acid power-supply battery 2 by a cable 4 and by a release mechanism which can be actuated by an acoustic signal from a surface vessel. An apertured dome resting on the bottom may be used to protect the beacon from bottom trawls.
