These liquids include aliphatic ethers and cyclic ethers, and particularly useful are glymes of the formula CH 3 O(CH 2 CH 2 O) n CH 3  wherein n is 1-4. A particularly useful solvent mixture is 50 wt.% ethanol and 50 wt.% glyme. A 6α-halo starting material may be prepared in situ, by placing the corresponding 6#-halosteroid in the solvent containing the acid catalyst and leaving it until epimerizing has been effected before addition of the ortho ester. When the starting material contains free 17α- and 21-hydroxy groups the product will be a 17,21-cyclic-ortho ester and this may subsequently be hydrolysed. The enol etherification may form part of the total process indicated in the following reaction scheme wherein R is alkanoyl and Z is an optional #<SP>1</SP>-double bond may be prepared similarly. Examples illustrate the foregoing procedures and compare the novel enol etherification process with similar known processes. In some examples 11-hydroxy starting materials are converted to 11-unsubstituted-#<SP>9(11)</SP>-steroids during the enol etherification.

Title: Alarm valve for a sprinkler installation
IPC: F16K37/00
Filed: 1963-01-25
Abstract: 999,071. Sprinkler system alarm valve. Z. J. SOSINSKI, J. J. G. C. HOPPENBROUWERS, J. SWEEP, and J. E. M. VAN IERSEL, [trading as SAVAL APPARATENFABRIEK C.V.]. Jan. 25, 1963 [Feb. 13, 1962], No. 3161/63. Heading A5A. A valve for operating the alarm system of a sprinkler system and usable when the system is of either the " wet " or " dry " type comprises a valve body resting on a seat in the pipe leading to the sprinklers and which is raised from its seating when liquid flows towards one or more sprinklers to allow entry of extinguishing liquid into the system and to an alarm device operated thereby and is characterized by having a third opening which is shut off by the valve in its closed position and which is connected, via an adjustable cock either with the alarm device or with the liquid contents of the system. The valve depicted in Fig. 1 (not shown) is used in conjunction with systems shown schematically in Figs. 2 and 3 which show the arrangement for " dry " and " wet " systems respectively. Referring to Fig. 2, the water supply pipe 2 with main valve 14 connects with the valve and is contained by the rubber diaphragm 8 which also seals off chambers 9 and 10 which are connected via pipes 15, 16 and 17 and 16, 17, 18 and cock 19 respectively to the alarm device. The outlet 3 leads to the sprinklers and at 20 there is a wide discharge pipe with valve 21. At 26, a pipe from the water-supply 2 leads to the alarm device and, via an adjustable cock 27 and non-return valve 28, to the chamber 10. In this arrangement, when a sprinkler operates, the air pressure above the diaphragm drops and the valve opens to allow water to pass to the sprinklers and also via the chambers 9 and 10 and associated pipes to the alarm. For testing, cock 31 is turned so that water reaches the alarm via pipes 26 and 30. The arrangement in Fig. 3 differs in that cock 19 and valve 27 are in different positions so that chamber 10 connects with the space above the diaphragm via pipe 23 and not with the alarm and water may pass into chamber 10 via cock 27 and non-return valve 28 when a pressure drop above the diaphragm allows. In this case, testing may be done not only by turning cock 31 but also by opening cock 25 to cause a pressure drop above the diaphragm.

Abstract: 865,000. Magnetic record apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 25, 1960 [Jan. 29, 1959], No. 3192/59. Class 40 (2). In a magnetic tape record apparatus, means are provided for stopping the drive of the tape and applying brakes to the spools when sensing means between the supply spool 1 or 2 and the capstan 10 and between the capstan 10 and the take-up spool 2 or 1 both sense that the tension in the tape has dropped to a predetermined level. In the embodiment described, the sensing means comprise jockey-pulleys 3, 7 mounted on spring-loaded arms 22, 23, respectively, which during the normal operation of the apparatus, are held away from the buttons of micro-switches 30, 31, respectively by the tension in the tape. During such normal operation, the switches are closed and motors 8, 9 apply a torque to the spools 1, 2 in opposing directions and keep the tape taut. At the same time, a motor 10 drives the capstan 10 and pressure rollers 11, 12 press the tape against the capstan 10 by means of solenoids 13, 14, respectively. Variable resistors 28, 29, connected to the arms 22, 23, vary the energization of the motors 8, 9 in accordance with variations of tension in the tape. During operation, solenoids 19, 20 are also energized to release brakes 17, 18, respectively, on the spools 1, 2. The switches 30, 31 are connected in parallel, and in the event of both switches breaking, such as when the tape breaks, motors 8, 9, 10 are switched off and the brake solenoids 19, 20 and pressure roller solenoids 13, 14 are released.
