Title: Improvements in door holders
Inventor: NICHOLSON THOMAS HENRY
IPC: E05B15/10
Filed: 1962-03-26
Abstract: 1,038,624. Door holders. DUNFORD FIRE PROTECTION SERVICES Ltd. June 26, 1963 [March 26, 1962], No. 11423/62. Heading E2A. An electrically controlled door holder for holding a door open is designed to be mounted adjacent to a door 16 and to receive within it a keeper 15 attached to the door, the door holder comprising a box within which is pivotally mounted a fastening member 9 movable between two positions to free or engage said keeper, resilient means 11 biasing the fastening member into one of said two positions and an electromagnetic solenoid 6 the armature of which is connected to the fastening member, the solenoid being operative when energized to displace the fastening member to the other of said two positions against the bias of the resilient means. In the construction shown the resilient means is a coiled compression spring 11 which normally holds the fastening member away from the keeper and energization of the solenoid coil is necessary to move the fastening member to the keeper engaging position and to compress the spring. A switch 19 is provided to enable the solenoid circuit to be broken to allow the fastening member to release the door. A plurality of such door holders can be used in large buildings such as hospitals, stores or office blocks to hold doors open, the solenoids being connected to a common controlling device e.g. an electrical fire alarm, a heat or smoke detector or a push button master switch so that all the solenoids can be released simultaneously to release the doors to allow them to close under the urge of automatic closers fitted to the doors. With this arrangement failure of the electric circuit also causes the doors to open. In a modification the solenoid and spring can be arranged so that the spring normally holds the fastening member in its keeper-engaging position the solenoid being energized to release the fastening member. In this modification, as an alternative to the switch 19, an actuator such as a rotary cam or a push rod can be provided for engaging the fastening member to displace it against the bias of the spring 11, the actuator having a portion projecting from the box for hand or pedal operation.

Patent GB-455014-A (GB)
Title: Process for the manufacture of esters of phosphoric acid
IPC: B64C17/00
Filed: 1935-04-13
Abstract: <PICT:0455014/IV/1> Organic hydroxy compounds are converted into their phosphates by passing a mixture of the hydroxy compound with phosphorus oxychloride, phosphorus pentachloride or phosphorus trichloride and chlorine through a series of zones of progressively increasing temperature.  Catalysts such as aluminium chloride or zinc chloride may be present, and the reaction is preferably effected, when using phosphorus oxychloride, under high vacuum or in the presence of an inert gas.  When using phosphorus pentachloride or phosphorus trichloride and chlorine, phosphite dichlorides are formed which require hydrolysis to the phosphates.  The process is applicable to the production of neutral phosphates containing the same or different alkyl or aryl radicles; the aryl radicles may contain an ether substituent.  Products mentioned are tributyl, triphenyl, tricresyl, trixylenyl, tri-(p-tert-amylphenyl), tri (ethylphenyl), tri-(methoxyethylphenyl), di(p-tert-amylphenyl)-monocresyl, mono(p - tert - amylphenyl)-monocresyl - mono (methoxyethyl) and di-(butylphenyl)-monophenyl phosphates.  The preparation of tricresyl phosphate by passing a mixture of 3 mols of cresylic acid and 1 mol of phosphorus oxychloride through three retorts maintained at 150, 225 and 300 DEG C. respectively is described.  The mixture passes by gravity from a mixing tank 11 to a preheater 13, thence through a flow meter 22 to three interconnected closed retorts 24, 27 and 28 arranged in series and located at different levels, and finally to a condenser 41.  Each retort, which is heated by a combustion chamber 25, is divided by baffle plates 26 and is provided with a pipe 53 for the supply of carbon dioxide or other inert gas.  Reflux condensers 43, 44 are connected to each retort and also to the preheater 13 for the return of condensible products while permitting the escape of hydrochloric acid gas to the flue 51 for recovery.  The flue is preferably fitted with a suction device in order to reduce the pressure in the retorts. Reference is also made to the production of tricresyl phosphate by leading a mixture of 3 mols of cresol with 1 mol of phosphorus pentachloride through 3 retorts heated to temperatures of 50 DEG  C., 75--100 DEG  C., and 100--125 DEG  C. respectively, and hydrolyzing the resulting tricresyl phosphite dichloride by treatment with water or caustic soda.  Specification 450,454 is referred to.  The Specification as open to inspection under Sect. 91 describes also the production of phosphites using phosphorus trichloride and refers to the preparation of tricresyl phosphite from cresol and phosphorus trichloride.  It also refers to the production of neutral phosphates containing alkoxyalkyl radicles, e.g. ethoxyethyl.  This subject-matter does not appear in the Specification as accepted.
