Title: 4-chloro-testosterone-17ª‰-acetate
IPC: C07J75/00
Filed: 1957-03-27
Abstract: 4-Chloro-testosterone-17b -acetate is prepared by reacting 4a , 5-epoxy-androstan-17b -ol-3-one acetate or 4b , 5-epoxy-etiocholan-17b -ol-3-one acetate or a mixture of these compounds with hydrogen chloride in solution in chloroform or methylene chloride e.g. at a temperature from -10 to 25 DEG C., and by acetylating 4-chloro-testosterone e.g. by means of acetic anhydride.  The acetylation process is preferably carried out in the presence of a basic reagent such as pyridine.  The chloroform used in the first process may contain about 10% of ethanol.  In addition the hydrogen chloride used in the first process may be in the form of a gaseous stream, or in the form of a salt with an organic base e.g. pyridinium chloride.  Detailed examples are given.  Specification 864,613 also is referred to.  Reference has been directed by the Comptroller to Specification 792,727.ALSO:A therapeutic composition comprises 4-chlorotestosterone 17b -acetate and a therapeutically acceptable carrier compatible therewith.  The carrier may be in the form of a liquid in which the active material is dissolved or suspended to form a composition for administration orally or by injection, of an ointment base to provide a composition suitable for topical administration, or of a solid or capsule.  Specification 864,613 also is referred to.  Reference has been directed by the Comptroller to Specification 792,727.

Title: Electric logic circuit arrangements using transistors
Inventor: SALAM HASSAN PADDY ABDEL
IPC: H03K3/037
Filed: 1965-06-17
Abstract: 1,134,226. Multi-emitter transistor logic. ENGLISH ELECTRIC COMPUTERS Ltd. 19 Sept., 1966 [17 June, 1965], No. 25710/65. Heading H3T. A multi-emitter transistor in a logic circuit has its collector connected to an output terminal, its base to a fixed potential and its emitters driven by respective emitter followers. Transistors 40-45 are normally non-conductive but when both transistors of any pair sharing a common emitter resistor are cut-off by the application data and control pulses to the respective bases, current flows to the corresponding emitter of the common emitter transistor 24 producing an output signal through emitter follower 56. The output signal is fed back to cut-off transistor 38 and since 39 is normally cut-off, the multiemitter transistor is maintained conducting until a reset pulse makes transistor 39 conduct. A further multi-emitter transistor 28 provides a constant bias voltage for the base of transistor 26 and the second emitter limits the voltage excursions of the collector of 24 to prevent saturation. A transistor 56 limits the voltage excursions of the output terminal, this being necessary since all diode voltage drops are compensated except that in transistor 38. Two logic circuits are shown and these may be made as an integrated circuit.

Title: An improved maximum demand meter for pulsating loads
IPC: G01R11/60
Filed: 1947-09-23
Abstract: 640,039. Supply meters. LANDIS & GYR SOC. ANON. Sept. 23, 1947, No. 25879. Convention date, Aug. 5. [Class 37] A maximum demand meter A connected to a pulsating load, for example welding apparatus 20, co-operates with a contact making device B wherein a cam disc 25 closes contacts 34 to zeroize driving pointer 14 when the aggregate of the load periods is equal to the pre-set recording period, for example 15 minutes. In B if the load is zero electromagnet 33 is deenergized and lever 30 brakes wheel 26 rigidly secured to cam disc 25 and sun wheel 24. This means that synchronous motor 23 drives sun wheel 21, planet wheel 27, planet shaft 28 and brake wheel 29. With recurrence of a load pulse electromagnet 33 is energized to operate lever 30 which brakes wheel 29 so that for the period of the pulse planet wheel 27 rotates about its own axis and drives sun wheel 24 and consequently cam disc 25 through a small angle. The sum of the load pulse times corresponding to the recording period is equated to 180 degrees on cam disc 25 which is therefore provided with diametrically opposite projections as shown to actuate switch 34. The planet shaft 28 may be driven constantly by the synchronous motor and the sun wheels or brake wheels connected with them are stopped alternately. The cam disc 25 may be driven (1) direct by the synchronous motor with the electromagnet applying a brake to the motor shaft except when a load pulse occurs ; (2) by step-by-step mechanism operated by the electromagnet 33 during each of the load pulses. The theory underlying the invention is explained with the aid of load diagrams, Figs. 1 and 2 (not shown).

Abstract: 241,574. Zbrojovka Praga Spolecnost s.r.o. Oct. 17, 1924, [Convention date]. Machine guns.-Firing mechanism, adjustable for single-shot and continuous firing and for safety, has a sliding sear - operating link formed with a rigid projection adapted to be acted upon by the bolt-carrier for singleshot firing. As shown, the mechanism comprises a trigger 5 mounted on a pivot c, a sear 2, a sear-operating link 4. hinged to the trigger, having a projection f and a T-shaped end a, b passing through an aperture in the sear, and a rotatable regulator 6 engaging the link 4 and formed with two flat surfaces 6<1>, 6<11>, Fig. 6, at different distances from the axis. The link 4 is normally pressed upwards into contact with the regulator by a spring 7. For single-shot firing, Fig. 1, the link 4 is in its uppermost position with the upper tooth a of the T-end engaging the sear. In this position, the projection f on the link projects into the path of the bolt-carrier 1 so that the link is depressed to disengage it from the sear after a shot has been fired. For continuous firing, the regulator is turned so that the rounded surface engages the link 4 as shown in Fig. 5. The lower tooth b of the link is then in engagement with the sear and remains in engagement after the firing of a shot. In the safety position, the end of the link is in a central position in the aperture in the sear so that it is inoperative.

Abstract: 854,006. Hydraulic couplings. SVENSKA ROTOR MASKINER A.B. Aug. 13, 1958 [Aug. 16, 1957], No. 26004/58. Class 69 (2). An hydraulic coupling comprises a housing 18 which is arranged on one shaft 19 of the coupling and provided with recesses 26 containing pairs of gears 28, 30 serving as gear pumps, one gear of each pair engaging a gear 16 on the second shaft 14 of the coupling, and each gear pump being provided with a pressure chamber 46 arranged radially-outwardly of the pumps so that the hydraulic pressure on each pump wheel is directed principally in a direction opposite to that of the centrifugal force acting on the wheel. The gears 28, 30 are supported on needle rollers 32 between the walls of the housing and one of each pair of the gears is spaced further from the centre of the housing than the other by the depth of the gear teeth. During relative rotation between the shafts, liquid in a central chamber 44 is pumped into the chambers 46 from which the liquid passes through circulation ducts 54 provided with relief valves 56 back to the central chamber. The valves are individually adjustable and may be arranged so that the bodies 58 of the valves are free or spring-urged outwardly, inwardly or parallel to the axis of the coupling to provide, with the centrifugal force acting on the bodies, the coupling with different output characteristics. In another embodiment, the axes of the gears of each pump are at equal radii from the centre of the housing and the radius of one wheel of each pair differs from that of the other by the depth of the gear teeth. Alternate pumps may be arranged to operate upon opposite rotation to permit the coupling to be used for forward and reverse rotation. Leaking past the sides of the gears is prevented by sealing plates 48 which are urged towards the sides of the gears by springs or liquid pressure supplied from the chambers 46. Specification 854,007 is referred to.

Abstract: Sugar juice is purified by treatment with an anion-exchange resin in hydroxide form to convert salts contained in the juice to their hydroxides, adding a metallic salt to give a water insoluble metal hydroxide with resultant coagulation of organic non-sugars. The insoluble hydroxide and co-agulated non-sugars are removed from the juice which is then contacted either with a mixed bed of anion - and cation-exchange resins or firstly with an anion - and then with a cation-exchange resins.  Molasses is first diluted with water and partially demineralized by treatment with an anion - followed by a cation-exchange resin before the final purification.  Specified salts are these of iron and manganese.
