Title: 1,3,5(10)-oestratrienes substituted in 3-position and a process for their manufacture
IPC: C07J41/00
Filed: 1960-10-27
Abstract: The invention comprises 3-chloro-D 1,3,5(10) -oestratrien-17b -ol acetate and the corresponding 3-iodo, 3-cyano and 3-xanthozenyl compounds, and a process for the manufacture of a 1,3,5(10)-oestratriene substituted in the 3-position by diazotizing a 3-amino-D 1,3,5(10)-oestratrien and then replacing the 3-diazonium group in the resulting compound by a hydrogen or halogen atom or by a cyano, mercapto, carboxyl, phosphoric, arsenic, nitroso or nitro group by a method known for the replacement of an aromatic diazonium group.  The reactants used in the above process may be further substituted more especially at the 17-position by a saturated or unsaturated alkyl group, or a hydroxy group or an ester group derived therefrom. A product containing a 17-ester group may be subsequently hydrolyzed to form the corresponding 17-hydroxy compound. Specification 938,432 is referred to.

Abstract: 1446031 Reciprocating pumps VALVE SYSTEMS INTERNATIONAL Inc 6 Aug 1973 [13 Sept 1972] 37192/73 Heading F1A In a hydraulically-actuated, flexible-chamber pump, a piston 50 reciprocates a liquid column acting on a tubular diaphragm 74 which acts through another liquid column to expand and contract a pumping tubular diaphragm 94. Piston 50 is driven by an electric motor 12 acting via worm 18, worm-wheel 28, eccentric 36 and a boss-head 44 detachably connected by pin 52 to piston 50, pin 52 being accessible via plug 53. A second pump may be driven by crosshead 44, as indicated in Fig. 1. The piston reciprocates in a sleeve 54 having an annular groove 60 communicating via ports 61 with an actuating liquid reservoir 22. Grooves 56 in the piston connect the working chamber of the piston to groove 60 to terminate the effective working stroke, sleeve 54 being axially adjustable, by rotating knob 62, to adjust the effective stroke. An indicator 66 shows the selected stroke setting. Movement of diaphragms 74, 94 is limited by perforated sleeves 80, 82, 96, surfaces 78, 98 of which by be curved, as shown, or straight Figs. 6 and 7 (not shown). A pressure relief valve 84, for the liquid column between piston 50 and diaphragm 74, discharges into a transparent viewing dome 86. Pumping chamber 100 has inlet and outlet ball-valves 104, 106. In Fig. 8 (not shown), diaphragms 74 and 94 are disposed coaxially.

[Class 103 (i).] Means for. adjusting the capacity of a fluid pressure brake system comprises a receptacle of adjustable capacity communicating with the system and means such as a spring for resisting the flow of fluid into and for expelling it from the receptacle when the pressure in the system is increased and diminished respectively. As shown, the receptacle 15 communicates by passage 23 with a master cylinder 10 containing a piston 11 adapted to force fluid through a conduit 24 to a brake or brakes. The receptacle comprises a diaphragm 18 urged downwardly by a spring 20 and its capacity is adjusted by a screw stop 22 against which the diaphragm abuts when pressure is established in the system. The device is particularly applicable to brake systems such as described in Specification 355,818 comprising two or more master cylinders and pistons operated by a common lever and adapted to supply pressure fluid each to a brake or series of brakes and serves to compensate for inequalities of volume in the several fluid systems so that equal pressures are established in the systems when the lever is operated.

Abstract: 1437540 Digital micrometer TESA SA 7 Aug 1973 [24 Sept 1972] 37435/73 Heading G1M A digital micrometer comprises a micrometer screw 2, a series of prisms 39 carrying indicating figures on their faces and arranged to rotate about the screw axis as the screw rotates, and a cam 46 arranged to rotate each prism about an individual axis 38 as the prisms rotate about the screw axis. Screw 2 engages a fixed support comprising tubes 1 and 5 by means of a tolerance compensation system 3 (not described). The screw is extended rearwardly by means of a shaft 4 to a ratchet drive 18, and a drive ring 15 is coupled to the shaft 4 by means of a hub 16 rigidly connected to the shaft 4 by a screw 17. The prisms, which may be 4, 5 or 6 sided, are arranged between arms 37 of a member 32 rotatably mounted on hub 16 by a ball bearing 33. As shown in Fig. 1, member 32 is rotationally coupled to screw 2 by means of hub 16, and a pinion 36 rotatably mounted thereon, pinion 36 meshing with teeth 35 on the member 32 and teeth 12 on a part 11 of the non-rotatable body 7 of the micrometer. Alternatively, a direct drive may be used to drive member 32 from hub 16. The cam 46 is arranged rotatably on the hub 16 so as to have both radial and axial float and is prevented from rotation with the hub 16 by means of an arm 48 engaging a stop member 49 on the body 7. The body 7 is mounted slidably at 6 on the tube 5 of the fixed support, and rotatably on the hub 16 by means of a ball bearing 14, a shoe 8 engaging a groove 9 in the tube 5 preventing rotation of the body 7. The body 7 includes a window 40 for reading the faces of the prisms and a scale on the member 32. As shown in Fig. 2, the faces of the prisms indicate tenths and hundreds of a unit and the calibration marks 42 on the member 32 indicate thousandths. In an alternative arrangement Fig. 3 (not shown), the faces of the prisms indicate tenths of a unit, and the member 32 is marked to indicate hundreds and thousandths. The micrometer may also include an arrangement for indicating the units digitally in a further window 23 of the body 7. The arrangement includes a tube 19 rotatably mounted in the body 7 and fixed axially relative to the body 7 by the bearing 21 and by the ball bearing 20. The inner wall of tube 19 has a pair of helical grooves 28, 29 each having a pitch equal to the measuring range of the micrometer and each being engaged by a pin 30 fixed to the tube 5 of the fixed support. As the screw 2 rotates and moves axially, body 7 and tube 19 also move axially, and the tube 19 is caused to rotate by the pins 30 engaging the helical grooves. Portion 22 of tube 19 carries a units scale visible in window 23. Specification 1437539 is referred to.

Abstract: 1423955 Burners JOH VAILLANT KG 30 Aug 1974 [4 Sept 1973] 38062/74 Heading F4T In an oil burner arrangement a fuel valve 4 is operated by an electromagnet 3 controlled by a relay 6 and a blower motor M is controlled by a relay 11 which operates faster than the relay 6. A heat-demand contact 14 closes and. a resulting charging pulse on the capacitor 15 unblocks transistor 21 which then conducts to operate relay 11, contact 10 switching on the blower motor and contact 31 holding on the relay. As the voltage at the base of the transistor 21 falls away it again blocks but current through resistor 23 is sufficient to hold relay 11. Voltage on the collector, at 22, rises and the Zener diode 27 conducts and hence transistor 28 conducts to operate relay 6. Contact 19 is controlled by a flame detector circuit comprizing an ionization electrode. If this contact opens, capacitor 15 then discharges via resistances 16, 17, 23 and relay 11 and the circuit resistance determines the secondary time. The apparatus can be re-started by actuation of the contact 14.
