Patent GB-967442-A (GB)
Title: Improvements in or relating to polyurethanes
Inventor: HAMPSON HORACE NEIL
IPC: C08G18/40
Filed: 1961-07-12
Abstract: In a process for the production of a polyurethane resin an organic polyisocyanate or polyisothiocyanate is reacted with a polyoxyalkylene polyol or a polyester having terminal hydroxyl groups in the presence of a modified glycidyl ether (which is defined as any reaction product of a glycidyl ether and any primary or secondary hydroxyamine).  The glycidyl ether itself may be formed from an epihalohydrin and a polyhydric organic compound, such as glycol, glycerol, pentaerythritol, sorbitol, poly allyl alcohol, resorcinol, hydroquinone, 2,2-bis(4-hydroxyphenyl) propane or 1,5-dihydroxynaphthalene. The adducts can be formed by the methods described in Specification 873,264.  A preferred polyoxyalkylene polyol is that described in Specification 967,441.  The polyesters having terminal hydroxyl groups include polyether polyesters.  The modified glycidyl ether can be produced by a fusion process or by reaction in a solvent such as ketones, esters or aromatic hydrocarbons.  Suitable hydroxy-amines are hydroxyaliphatic amines; bis(hydroxyaliphatic amines); N-hydroxyaryl-N-aliphatic or aryl amines; hydroxyaryl amines; bis(hydroxyaryl) amines N-hydroxyaryl-N-aliphatic- or aryl amines and N - hydroxyaliphatic - N - hydroxyaromatic amines.  A polyurethane resin having terminal isocyanate or isothiocyanate groups is obtained by using an excess of the organic polyisocyanate or polyisothiocyanate.  A primary or secondary amine can be added to stabilize these resins. The resins can be used in lacquers; converted into a synthetic rubber by heating with inorganic or organic bases and/or a surface active agent; or converted into a polyurethane plastic by reaction with a compound containing active hydrogen atoms such as water, glycols, amines, dicarboxylic acids hydroxyamines or hydroxy-or amino-carboxylic acids.  The plastics can also be prepared by a one-stage process, and this may be effected in the presence of an organo tin catalyst, and/or a basic catalyst, and/or a silicone oil and/or a solvent such as hydrocarbons, carbon tetrachloride, ethyl or amyl acetate. Cellular polyurethane plastics are obtained by reacting the polyurethane resins with a compound containing active hydrogen atoms under conditions whereby carbon dioxide or carbonoxysulphide is produced, if desired, in the presence of a volatile halohydrocarbon and/or an inert gas.  Alternatively the reaction can be conducted as a one-stage process.  Specifications 631,991, 681,001 and 945,153 also are referred to.

Title: Improvements in or relating to self-priming pump systems
Inventor: MEYER ALFRED WALTER
IPC: F04D9/00
Filed: 1959-07-24
Abstract: 895,914. Centrifugal pumps. ATKINSON CO., GUY F. July 24, 1959, No. 25575/59. Class 110 (1). A self-priming pumping system comprises a closed suction well 10 holding priming liquid, an inlet connection 12 at the top of the well, a pump 11 in the well, an accumulating chamber 60 above the well, a discharge pipe 63 communicating with the top of the chamber, means such as the check valve 62 to prevent back flow from the pipe to the chamber, ports 36 in the conduit communicating with the well and a valve 40 in a housing 30 actuated by pump discharge pressure to close the port and to pass discharge from the pump to the chamber and on cessation of discharge to pass a return flow from the chamber through the port to the well to reprime the pump and passing air from the well to the chamber so that the discharge of liquid in the next pumping cycle will force the air from the chamber to the discharge pipe. Upon starting the pump, the suction well 10 and the accumulating chamber 60 normally contain liquid and air respectively and the valve member 40 is on its seating, Fig. 6. The pump discharge flows from passages 21, through holes 47 and 51 of the valve member and the liquid pressure moves the valve to its uppermost position, Fig. 3. Ports 34, which communicate with the discharge conduit are opened, the ports 36 which communicate with the well and the discharge flows through the body of the valve and passageways 35, discharge conduit 25, into the chamber 60. When the pressure in the chamber 60 exceeds the static head in the pipe 63, the check-valve 62 opens and the air in the chamber is discharged through the pipe. As the liquid level falls in the well, the pump starts to run dry and the pressure in the chamber 60 falls, the check-valve 62 closes and the valve 40 begins to fall until the liquid within it is vented through openings 47 and 52 into the ports 36 to the suction well. This allows the valve 40 to drop rapidly to its lowermost position, Fig. 6, thereby permitting free flow of liquid through conduit 25 and ports 36 from the chamber 60 to the well 10. Air from the upper part of the well flows through pipe 65 and check-valve 66 to replace the liquid in the chamber. This cycle is repeated until the air is exhausted from the suction system when a continuous flow of liquid is pumped into the chamber 60, through the check-valve 62 and through the discharge pipe 63.

Abstract: 798,916. Vacuum railway brakes. KOFLER, G. Aug. 22, 1956, No. 25623/56. Class 103 (1) In an automatic vacuum brake system for railway vehicles wherein a tripping arm 28, movably mounted on a convenient structure at the side of the track is pivotable, so as to hit, or not hit, a striker arm 29 carried by the train, the arm 29 is arranged, when depressed, to close a valve 44, thus shutting off communication between passage 50 leading to the brake control pipe 46 and a pipe 51 leading to a vacuum reservoir 60, and to open a valve 43 allowing air to enter the pipe 51 through pipe 59 and an air inlet hooter warning device 58. The increase of pressure in pipe 51, by acting below diaphragm 52, causes the latter to be displaced upwardly thus opening valve 54 so that air is then enabled to enter from the atmosphere through ports 57, directly into the brake pipe 46, so that a brake application is rapidly brought into operation.

Filed: 1955-09-07
Abstract: 782,227. Keyboard switches. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 7, 1955 [Sept. 10, 1954], No. 25637/55. Class 38 (5). [Also in Group XXXVIII] A switching device comprises individual switches, some of which are controlled by parallel sliding rods, there being provided a separate switch which controls a sliding rod for locking the first-mentioned switches in certain positions, the locking rod being arranged transversely to the direction of movement of the parallel rods, the latter and the locking rod having cooperating recesses therein. As applied to a magnetic recorder, buttons 1 and 2 respectively control the rapid reverse and forward coiling of the sound carrier, buttons 3 and 4 respectively control the reproduction and recording, and a rotary knob 5 controls the normal movement of the sound carrier. Each button has a rod 8 slidable in a frame 6 and having a notch 9 co-operating with the frame to lock the buttons in their depressed positions. Buttons 1, 2 also have notches 11 co-operable with a sliding rod 14 connected to the knob 5 by a link 13. The rod 14 has notches 19 and a pivoted lever 21 lying across the notches 19, so that when notches 11 and 19 coincide, depression of e.g. button 1 causes a sloping surface thereon to tilt the lever 21 counterclockwise into notch 11 of button 2 which is thereby locked. The rod 8 of button 1 also enters the right-hand notch 19 and locks the rod 14. An extension of the rod 14 (Figs. 8, 9, not shown), or a lever 16 pivoted thereon, co-operates with the rods 8 of buttons 3 and 4 so that when knob 5 has been operated buttons 3 and 4 cannot be depressed. In addition, if button 3 or 4 is depressed and knob 5 is then operated, the said button is locked down and the other prevented from operation.

Title: Improvements in method of making embossed electric battery separators
IPC: B29C43/22
Filed: 1952-10-14
Abstract: 715,448. Batteries. UNITED STATES RUBBER. CO. Oct. 14, 1952, [Jan. 4, 1952.] No.25686/52. Class 53. [Also in Group VIII]  Separators are made from a fibrous cellulose sheet which is impregnated with a phenol formaldehyde, phenol furfural, melamine formaldehyde or other resin and partially dried and then embossed by pressure and finally heated to cure the resin. Figs. i and 2 show apparatus for carrying out the process in which 10 is a roll of paper which is unwound and passed through a tank I5 containing a solution or suspension of the resin. Rolls I7 squeeze out excess liquid and the impregnated sheet is passed through a drying chamber I9 and wound into a roll 24. The roll is transferred to the apparatus shown in Fig. i and is shown at 24<SP>1</SP> from which the sheet I is drawn and passed between heated plates 28, 29 and then between embossing rollers 31, 32. Cracking of the sheet as it passes between the rollers is prevented by covering it on both sides with protecting aprons 35, 36 which may be made of metal foil, plastic film or a stretchable fabric. The aprons are in the form of endless belts which on the sides that come into contact with the sheet may be coated with rubber and talc the latter being applied by rotating brushes 43, 46. The aprons are kept taut by weights 39, 42 and slidable rolls 37, 4I round which the aprons pass. The embossing rollers 3I, 32 produce ribs on the sheet which are slightly higher than required and which are reduced to the required size by accurately spaced rollers 50. The sheet then passes through a curing chamber heated by two electric heaters 51, 52, Fig. 4, situated in housings 53, 54 hinged together at 55. The housing 53 can be raised by a handle 56. The embossed and cured sheet is sprayed at 58, 59 with a wetting agent and the sides trimined by cutter discs 6o which are driven by a motor 64 which also drives rollers 62 which draw the sheet through the apparatus from the roll 24<SP>1</SP>. The sheet is cut into short lengths by a cutter 67.
