Title: Improvements in or relating to the production of acrylate esters
Inventor: PERCY ERIC JAMES
IPC: C07C69/54
Filed: 1966-01-19
Abstract: 2-Hydroxyalkyl acrylates and methacrylates are prepared by reacting acrylic and methacrylic acids with alkylene oxide in the liquid phase at an elevated temperature in the presence of nitric oxide as a polymerization inhibitor, and a solid anion-exchange resin containing basic nitrogenous groups with trivalent nitrogen atoms which is insoluble in the reaction mixture, as a catalyst. Anion exchange resins may be cross-linked polystyrenes with a mixed aliphatic amine group present as a mineral acid salt, or with vinyl pyridine copolymerized therein, or thermosetting resins prepared by the condensation of aniline with formaldehyde, or formaldehyde and phenol.  Ethylene, propylene and butylene oxides, epichlorhydrin and styrene oxides are mentioned as the alkylene oxides.

Abstract: 651,075. Oilcans; spouts; stoppers. METAL BOX CO., Ltd., JACKSON, J. M., and BENNETT, H. J. Jan. 29, 1948, No. 2701. [Classes 66 and 125(iii)] An oil can 1 has a tubular spout 7 for pouring oil into small holes, slidingly mounted in a sealing grommet 3 having: surfaces fitting the outer surface and the edge of a flange 2 around the filling hole in the can. The spout may have a nozzle 7a and shoulders 11 and 15 which determine the spout's extreme extended and retracted positions. A captive cap 13 or a plug formed on a flexible strip integral with the grommet 3 may close the nozzle. The edge of the flange 2 may abut a shoulder 5 on the grommet which may be double frusto-conical in shape.

Title: Improvements in or relating to delivery control valves
IPC: F04C14/26
Filed: 1962-01-25
Abstract: 977,344. Valves. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATURENFABRIK KOMM.-GES.]. Jan. 25, 1962 [May 5, 1961], No. 2830/62. Heading F2V. [Also in Division G3] A delivery control valve, particularly for a rotary vane pump 4, in which a control piston 12 moved against the force of a spring by the pressure difference across a baffle 13 in the delivery pipe to permit fluid delivered by the pump in excess of the quantity determined by the baffle to flow to a tank 3, has a pressurelimiting valve 14 disposed in the piston, operated by the pressure downstream of the baffle and closed by a spring which also operates on the piston 12. The valve is connected to a stop valve 8, amplifier 5 and accumulator 9. When the pump 4 is running fast, the excess delivery forces the piston 12 to the left against springs 17 and 18 so that a groove 22 connects grooves 19 and 20 to provide a direct passage to the tank 3. After the spring 18 has been compressed sufficiently for the end face of the piston 36 to engage a collar 24, delivery is controlled solely by the spring 17 until the pressure in a chamber 34 acting through a passage 33 and a restriction 37 on the annular right-hand face of the sleeve 14 lifts the latter to allow fluid to drain from a chamber 35 through an annular space 31 to the tank 3. As the chamber 35 is drained more quickly than it can be filled the pressure within it falls and causes the piston 12 to move further to the left. When the pump is running slowly, the accumulator may be at a higher pressure than the pump delivery so that there is no flow through the baffle 13, the piston 12 is moved into engagement with the baffle by the springs 17 and 18 which are fully extended, and the valve 14 is opened by the pump delivery pressure against the tank pressure acting on the annular face 30, the closing force on the valve 14 being proportional to the delivery through the baffle 13.

Lists of typical plasticizers, resins and other additions are given. Examples are given of the use of alcohols or mixtures of alcohols and ketones, obtained by hydrogenation of an alkaline condensate of mesityl oxide, to form coating compositions with polyvinyl acetals or a vinyl chloride/vinyl acetate interpolymer, using ethyl alcohol as a solvent.

Title: Improvements in diversity radio receiving systems
IPC: H04B7/08
Filed: 1946-02-01
Abstract: 617,254. Radio receiving systems; frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 1, 1946, No. 3323. Convention date, Feb. 1, 1945. [Class 40 (v)] In a diversity receiver the several channels are combined over gate valves controlled by rectified I.F. signal energy. The channels X, Y, Z, Fig. 1, terminate in detectors R, R<1>, R<11> respectively, producing audio signals which are combined on the line 12 over transformers 5 and gate valves 2. In each channel a branch 4 feeds I.F. energy to a rectifier 1, the output of which, after removal of I.F. and modulation components by a filter 6, is applied as a gate voltage to the corresponding gate valve 2. By combining the bias potentials in the resistance 10, the strongest signal biasses the gate valves in the remaining channels to beyond cut-off. A group of rectifiers M fed from the individual channels supplies a combined A.V.C. potential to all channels over the lead A.V.C. In a modified arrangement (Fig. 2, not shown) the channels are combined at the I.F. stage, the cathode of the diode gate valve 2 being coupled to the anode of the rectifier 1 over a condenser passing I.F. energy. A further arrangement (Fig. 4, not shown) employs triode gate valves, the signals and positive-going gating potentials being applied to the grids and the output being taken over a common cathode resistance. In the combination of I.F. signals, cancellation may occur at the common resistance 10 if two predominating signals are of similar amplitude but opposing phase. In a modification, Fig. 3, for the reception of frequency-modulated signals and arranged to overcome this effect, there is provided in addition to a limiter stage 31 and discriminator 32 tuned to the intermediate frequency a further channel comprising a limiter 35 and discriminator 36 tuned to the second harmonic of the intermediate frequency, which does not cancel in such a circumstance. In a modification (Fig. 5, not shown) of the first arrangement, Fig. 1, for frequency modulation signals, the transformers 5 are omitted, the gate potential produced by the rectifier 1 in each channel being applied to the corresponding gate valve 2 in series with the output of a discriminator circuit terminating the channel.
