Title: Curing compositions containing cyclic phosphorus nitriles and carboxamides
Inventor: PEFFER ROLAND JOSEPH
IPC: C08G59/40
Filed: 1966-02-15
Abstract: Carboxylic-group containing polymers and epoxy resins are cured using a novel curing composition comprising a mixture of between 1:5 and 5:1 by weight of (1) a liquid cyclic alkylenimidophosphorus nitrile of the formula <FORM:1086601/C3/1> where n is 1 or 2, and R is an alkylenimido group of formula <FORM:1086601/C3/2> where X1 and X2 are hydrogen, phenyl, or alkyl of 1 to 4 carbon atoms, and (2) a liquid carboxamide of formula <FORM:1086601/C3/3> where r is 2 or more, and Z is an r-valent aliphatic, aromatic, or alicyclic radical which does not contain active hydrogen atoms. The polymers may be polyesters, polyethers, polybutadienes or butadiene-acrylonitrile copolymers which are modified or chain-terminated with carboxyl-containing compounds, but are preferably liquid low molecular weight polyesters of a diol, a dibasic acid, and a polyanhydride, polyol or polybasic acid, e.g. the polyesters prepared from isosebacic acid, neopentylglycol, and trimethylolpropane, and having a molecular weight of 3000 to 4000.  The cured polymers may be moulded, and may contain various fillers, e.g. SiO2, TiO2, ZrSiO4 or plasticizers. Comparison tests utilizing either a compound of the type (1) or a compound of the type (2) alone are also described. The cured polymers find use in tarpaulins, radomes, electrical insulation, storage and shipping containers, clothing, shoes, upholstery, shell liners, propellant devices, adhesives and sealants.ALSO:Bis-1,2-alkylene carboxamides, useful as components of curing compositions for polyesters, are prepared by reacting an alkyleneimine in an aqueous phase with a solution of a dicarboxylic acid halide, in a water-immiscible organic solvent, in the presence of an acid acceptor, and at a temperature of -5 DEG  to 30 DEG  C. In the example, N,N1-bis-ethylene-isosebacamide is prepared from ethyleneimine and isosebacoyl dichloride.

Title: Self posing device for portrait photography and portrait filming
IPC: G03B17/53
Filed: 1946-03-04
Abstract: 624,173. Photographic studio apparatus. FOUFOUNIS, J. T. March 4, 1946, No. 6710. Convention date, April 5, 1945. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 4, 1946.] [Classes 98 (i) and 98 (ii)] A photographic or cinematographic camera. is combined with a self-posing device comprising a finder objective having its optical axis close to and parallel with that of the camera, an electronic iconoscope on the mosaic of which an image of the user is formed by the finder objective, an amplifier connected to the iconoscope, a cathode-ray tube display unit fed by the amplifier and having a luminescent screen on which the image formed by the finder objective is reproduced, and means for operating the camera from the place occupied by the user. In a modification, the finder objective is omitted and the image is formed on the iconoscope mosaic by the camera objective. As shown, an image of the operator, standing at 0 in front of the camera 14, is formed by a lens 5, the optical axis of which is parallel and close to that of the camera, on the mosaic 1 of an iconoscope. Following usual television practice, the mosaic is scanned by an electron beam from the cathode 2, and the signals are passed through an amplifier 10 and cable 11 to a cathode-ray tube 6. Scanning in the iconoscope and cathode-ray tube is effected by coils 3 and 9 respectively, supplied by a common time base generator 4. The cathode-ray tube and associated parts are carried by an arm 15 pivoted at 16. The image on the mosaic 1 may be formed by a reflex arrangement in the camera, and the shutter is actuated through a cable connection by a release knob or treadle 18 within reach of the operator. The Specification as open to inspection under Sect. 91 states that (1) the operation of the release knob or treadle 18 may ignite a flashlight, and (2) the arm 15 may be replaced by a parallel-motion linkage.

Title: A system of modulating high frequency currents of thermionic tube transmitters for wireless purposes
IPC: H03C1/22
Filed: 1926-03-10
Abstract: 277,390. Mandelstam, L., and Papalexi, N. March 10, 1926. Thermionic modulating systems and apparatus; thermionic generators.-Modulation of the high frequency currents of a thermionic valve, which may be a drive oscillator or an amplifying valve, is effected by a variation in the high frequency voltage acting on the grid, which voltage is produced in an impedance inserted in the grid-filament path. The grid current flows through the impedance, which is so proportioned that the current flowing is mainly determined by the gridanode capacity of the valve. Fig. 2 shows an arrangement in which the grid circuit impedance 3 is constant and the current flowing is varied by variation of the grid-anode impedance. The grid-anode capacity is shunted by a condenser 10 and an inductance 11 and modulation is effected by varying either of these. Alternatively a constant grid current may be employed and the impedance 3 may be varied, e.g. as shown in Fig. 4, in which two auxiliary magnetized chokes are employed, the windings 31, 32 of which form the high frequency impedance, which is variable by means of the windings 141, 142 fed from a microphone circuit 13. In a modification, the impedanca 3 is shunted by the anode-cathode path of an auxiliary valve, the impedance of which is varied in accordance with the low-frequency input. Formulµ and a numerical example are given in the Specification showing how the value of the impedance 3 is determined.

Patent GB-627339-A (GB)
Title: Improvements in and relating to the production of dried eggs
IPC: A23B5/025
Filed: 1947-03-13
Abstract: In a method of producing dried egg yolk or dried whole egg the yolk is first subjected to a suitable heat treatment and then the heat treated yolk is dehydrated preferably by spray drying or the heat treated yolk and the white are subjected to simultaneous spray drying in the same chamber without mixing the said materials before spray drying.  The suitable heat treatment is one carried out at such temperature and during such time sufficient to inactive or destroy enzymes present in the yolk capable of deteriorating the taste of the dried product.  It should preferably be carried out while moving or agitating the yolk mass in a finely-divided state to ensure no aggregates being formed, e.g. in an apparatus having a quickly rotating perforated worm surrounded by a hot-water jacket, in which the yolk is heated for 1/2 minute to about 84 DEG C.  In a modification, heat treated and if desired dehydrated egg yolk is dispersed in the white and this dispersion is dehydrated preferably by spray drying.  The heat treatment of the yolk may be combined with the addition of antioxidants, e.g. of hexosephosphate type, or with addition of glycerol or sugar.  The keeping qualities may be improved by altering the acidity of the yolk by adding prior to dehydration a suitable acid or base, the acidity of the white being correspondingly altered in the opposite direction by adding a suitable base or acid to obtain by dehydration a powder which on solution shows substantially the same acidity as the original material.  Suitable acids are HCL CH3COOH and bases are NH4OH, NaOH, NaHCO3 and like alkali bases.  In producing dried mixtures of egg yolk and white the heat treatment may be combined with fermentation of the white.  In an example, 315 Kg egg yolk are placed in a cylindrical vessel provided with a hot-water jacket and having a perforated rotating worm. Whilst the worm rotates the yolk is brought to 82 DEG C. and kept for 1/2 minute and then transferred to another vessel and after cooling to below 35 DEG C. is mixed with 560 Kg egg white and spray dried.

Abstract: 874,876. Surgical syringes. ESCHMANN, M. March 1, 1960 [July 29, 1959], No. 7293/60. Class 81 (2). The plunger rod of a syringe is fitted with a valve device which restricts the escape of air as the plunger is retracted, so as to prevent the rapid retraction of the plunger, which might break the end cap of the syringe. The valve member 5 consists of a resilient sleeve having a radial flange 5a, which is received in recess 2b in the end cap 2. The upper face of this recess is planar so that the flange seats against it when the plunger rod 3 is drawn backwards and air can only escape from the enclosed space slowly. The lower face 2d of the recess is non-planar so that air can pass freely when the plunger is pressed downwards and its movement is unrestricted. The extension 5b of the valve member beyond the lower face of the end cap additionally serves as a resilient buffer against which the piston abuts when fully retracted.
