Title: Improvements in and relating to lasers
IPC: H01S3/082
Filed: 1964-02-19
Abstract: 1,028,643. Lasers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 19, 1964 [Feb. 22, 1963], No. 6949/64. Heading H3B. A laser comprises an active medium 1, Fig. 2, having a wholly reflecting mirror 2 at one end and a partially reflecting mirror 3 at the other end, the partially reflecting mirror being arranged at an acute angle to the optical axis 8 of the laser so that radiation 12 emitted by the active medium is partially transmitted (14) to a mirror 5 and partially reflected (13) to a mirror 4, the reflected radiation 15, 16 from the mirrors 4, 5 being again partially reflected (17), (20) and partially transmitted (18), (19) at the partially reflecting mirror 3 whereby radiation portions 17, 19 from the mirror 3 are directed back to the active medium and radiation portions 18, 20 form the ultimate laser output. The optical path between the partially, reflecting mirror 3 and one of the mirrors 4 or 5 is adjustable by a piezoelectric or magnetostrictive member 22 which displaces the mirror 4, 5, or by an electrooptical body positioned in front of one of these mirrors, the adjustable path having an effect equivalent to controlling the transparency in the output path of the emitted laser radiation, so that the optical load may be matched to the active medium to give maximum operating efficiency. The active medium may be either gas such as helium-neon enclosed in a glass tube or a rod-shaped ruby. In Fig. 3, the partially reflecting mirror 3 and the mirror 5 comprises metallized surfaces of a glass or quartz body 30 formed of two parts 31, 32 secured together by clamping or cement. Alternatively the partially reflecting mirror may consist of a half wavelength air gap. A piezo-electric cylinder 36, e.g. barium titanate which has inner and outer gold electrodes 37, 38, is cemented to face 34 of the body 30 and has mirror 4 secured to its other end, the length of the cylinder being controlled by a voltage source 41. An application to a ruby laser is shown in Fig. 4 in which the ruby has a diagonal end surface, the end portion of the ruby serving as part 32. Antireflection surfaces are provided in these embodiments, but are not required in Fig. 5 in which all radiation entering and leaving the transparent body 30 is at the Brewster angle 13. In Fig. 5, the shape of the piezo-electric crystal is modified as shown. Fig. 6 shows an electro-optical body positioned between mirrors 3 and 4 for the purpose of controlling the optical path length, the body comprising a crystal 80 of KH 2 PO 4 , for example, having transparent and conductive tin-oxide layers 81 connected to a voltage source 84. Flat reflecting surfaces which are normally used may be replaced by curved surfaces or right roof prisms.

Filed: 1945-03-21
Abstract: <PICT:0595797/IV/1> In a machine 9 for making stuffed products, e.g. sausages, the casing is formed from a strip of cellulose material 14 on a spool 13.  The sheet is formed into a tube at 15 (see Group VI). A reservoir 27 of alkali adhesive has a wick 17 to wet the adjoining edges of the tube, the joint being sealed by a spring-pressed roller 19.  The cellulose material is alkali-soluble, water-insoluble and may comprise carboxy-alkyl cellulose ether, cellulose ether-xanthates, cellulose xantho-ethers, cellulose thiourethanes and cellulose xantho fatty acids.  The alkali adhesive comprises a solution of sodium hydroxide, potassium hydroxide, lithium hydroxide, a quaternary ammonium base, and strong organic amines.  To this solution may be added an alkali-soluble, water-insoluble cellulose ether to increase its viscosity.  A solution of sodium hydroxide 8 per cent and ethyl cellulose 5 per cent is preferred.  Alternatively, regenerated cellulose films, and organic solvent-soluble synthetic resins may be used, the adhesive being tribenzyl methyl ammonium hydroxide or a solution of 10 per cent sodium hydroxide and 8 per cent alkali-soluble, water-insoluble cellulose ether.  With strip formed of cellulose acetate or a copolymer of vinyl chloride and vinyl acetate, the sealing solvent may be acetone; when using organic solvent-soluble ethyl cellulose, the solvent may be ethyl acetate. The tube may be formed of thermoplastic, such as copolymers of vinyl chloride and vinylidene chloride, fibre-forming synthetic linear polyamides and chlorinated rubber. Examples of the use of some of the materials are given.  Stripped casings may be cleaned, redissolved and recast into sheet for the further production of tubes.

Title: Logarithmically responsive electronic circuits
IPC: G01R15/00
Filed: 1946-03-11
Abstract: 624,313. Current and voltage measurements by vacuum or low pressure discharge apparatus. GENERAL ANILINE & FILM CORPORATION. March 11, 1946, No. 7559. Convention date, Dec. 30, 1944. [Class 37] [Also in Groups XL (b) and XL (c)] In order that an instrument used for indicating a quantity logarithmically related to the quantity which actuates the instrument may have a substantially uniform scale, the dynode stage voltages of an electron multiplier tube supplying the instrument are varied inversely as the anode current of the multiplier. In the application shown in the Figure, the density of a film 17 is measured by passing a beam of light through the film and measuring the light flux falling on the cathode 16 of a photomultiplier tube 20 by means of a meter 25. Since the density is proportional to the logarithm of the reciprocal of the light flux falling on the tube and the anode current of the tube is linearly proportional to this light flux the instrument 25, would normally indicate film density on a logarithmic scale. To make the scale linear, however, the stage voltage of the dynode is varied inversely as the anode current, it being shown in the Specification that if the stage voltage is linearly related to sample density, i.e. inversely to anode multiplier current, the instrument current will be suitably amplified to provide a uniform scale. Accordingly, the anode output current of multiplier tube 20 is fed through a resistance 41, the P.D. across the resistance being used to bias negatively the grid of a tube amplifier 35 in series with a potential divider 30 so that increase in anode current of the multiplier increases the impedance of the valve reducing the dynode stage voltage and suitably modifying the reading of the instrument 25 in series with the anode of the amplifier tube. To prevent the instrument pointer from tending to fly off the scale when sample density is infinite, a bucking voltage is supplied to the instrument by the cell 43. In a modification the instrument 25 is inserted in the anode circuit of the multiplier. Specification 601,465, [Group XL (b)], is referred to.
