Abstract: 1,178,325. Phase modulation. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 26 May, 1967 [27 May, 1966], No. 24744/67. Heading H3R. In a phase modulator, a carrier source V e  is connected to two phase shift networks LR1 and CR2 which are connected to opposite ends of a pair of voltage-variable capacitors D1 and D2, the junction of which is connected to the modulation source V m  and coupled to the output through a transformer T having its secondary winding tuned to the carrier frequency. In Fig. 1, the capacitors are varactor diodes which are biased by sources E1 and E2 which are by-passed for A.C. by capacitors C1 and C2. In a modification, Fig. 2 (not shown), the capacitors are the base-emitter junctions of two complementary transistors. The output is amplitude-modulated as well as phasemodulated, and the amplitude modulation may be removed by limiters (not shown).

Abstract: 666,447. Feedwater supply systems for locomotive boilers. KRUPP LOKOMOTIVFABRIK, F. Sept. 27, 1949 [Oct. 1, 1948] .  No. 24779/49. Class 123(ii) In a feedwater supply system, Fig. 1, for a locomotive boiler, not shown, which includes a high-pressure injector pump 9 discharging through a pipe 16 to the boiler inlet valve 17, the pump 9 is supplied with a mixture of cold and preheated water from a header 2 by an auxiliary lowpressure injector pump 5 having a discharge pipe 6 provided with a thermometer 8. The header 2 has an inlet 1 from a tender, not shown, and an inlet 3, including a reserve tank 26, leading from a preheater 21 which is supplied with water from the discharge pipe 6 of the pump 5 through a branch 18, fitted with an adjustable throttle valve 19 and terminating in a spray tube 20, and with exhaust steam from the driving and auxiliary engines of the locomotive through pipes 22, 23, 24. The steam inlets of the two injectors are connected to a common steam pipe 10, the injector 9 through a valve 11 and branch 13, said latter injector also being provided with a shut-off valve 14 and a condensate escape pipe 15. The preheater 21 is vented at 27 to atmosphere. Instead of a single auxiliary injector pump 5 there may be two 28, 29, adapted to supply water, respectively, to the main injector 9 and to the preheater 21. Such an arrangement is shown in Fig. 4 in which feedwater is supplied to a boiler by an injector pump 9 or, alternatively, by a piston or centrifugal pump 33, the latter having steam inlet and outlet connections 34, 35, also water inlet and outlet connections 32, 36 leading from and to the preheater 21 and second boiler inlet valve 37 respectively. When the pump 33 is in operation the injector pump 9 and its associated auxiliary injector 29 are cut out.

Abstract: 843,328. Hydraulic presses. NATIONAL AUTOMATIC TOOL CO. Inc. Aug. 1, 1958 [Aug. 26, 1957], No. 24880/58. Class 69 (2). A ram 12 of a moulding machine is advanced rapidly by supplying liquid from a pump 42 through a valve 56 to a booster cylinder 15 formed in the ram. A pilot pump 44 supplies liquid through a valve 58 to a valve chamber 23 to unseat a valve 26 from a seat 28 so that liquid from a reservoir 46 supplies oil to the ram cylinder at the rear of the ram. Towards the end of the advance stroke a dog 72 on the ram actuates a switch LS-2 which actuates valve 58 so that valve chamber 23 is opened to exhaust and the valve 26 seated by a spring 30. The valve stem 24 uncovers ports 32 so that pump 42 in addition to supplying the booster cylinder supplies to the main ram cylinder 10, to give a slower speed. This prevents harmful impacts between the moulds and gives full clamping force. When dog 72 actuates a switch LS-3, valve 58 is actuated and valve 56 reversed so that liquid is supplied to a pull-back area 34 of the ram which is retracted rapidly. At the end of the return stroke a switch LS-1 is opened to stop the operation.

Abstract: 1, 048, 807. Sewing machines. INSTITUT FœR TEXTILMASCHINEN. June 14, 1965, No. 25084/65. Heading D1G. In a sewing machine having a work holder secured to a mechanically-driven carriage guided by a member thereon engaging a fixed stencil plate, the drive is derived from a shaft to which oscillation of adjustable magnitude is imparted from a motor-driven shaft via a stitch-regulating device, and which drives the carriage via free wheel clutches. A carriage 4 has a vertical pin 5, to the upper end of which a work clamp is secured, and the lower end of which engages a pattern groove 8 of a fixed stencil plate 9. Carriage 4 is movable on parallel bars 11, 12 interconnected at their respective ends by plates 14, 15 movable on parallel bars 17, 18 perpendicular to the bars 11, 12. Rotary shafts 19, 20 are interconnected by endless driving belts 22, 23 secured to plates 14 and 15 respectively, and shaft 19 is driven by a belt 64. Plate 14 journals a pulley connected by an endless belt 27 to a pulley which is journalled on plate 15 and is slidably keyed to a shaft 24 driven by a belt 69. The normal feed-advance shaft of a sewing machine 3 carries a pair of cranks 48, 49 coupled to respective freewheel clutches in a gear box 51. Said clutches are arranged to rotate in opposite directions, and one or the other is adapted, by the selective energization of solenoids 84 and 85 to be coupled to a gear 56, Fig. 8 (not shown). A gear 57, in constant mesh with gear 56, is adapted by the selected energization of solenoids 86 and 87 to be coupled to one or the other of output shafts 60 or 66 of gear box 51. Shaft 60 is coupled to belt 64 for shifting the work holder transverse to the longitudinal axis of the sewing machine 3. Shaft 66 is coupled to belt 69 for shifting the work holder parallel to said longitudinal axis. The solenoid 84 to 87 are selectively energized by the lower end of pin 5 engaging contacts disposed in groove 8. The arrangement is such that, to shift pin 5 from the starting point 91 to point 93, shaft 66 is driven in one direction, to shift pin 5 from point 93 to point 94 shaft 60 is driven, and to shift pin 5 from point 94 to the finishing point 95, shaft 66 is driven in the opposite direction. To return pin 5 to the starting position, shaft 20 is driven via a belt 99 by an auxiliary motor 96. The base plate of sewing machine 3 is arranged to tilt upwards about a horizontal pivot pin, and to enable such tilting to occur without releasing the connection between the cranks 48, 49 and the feed advance shaft, the latter is made in two sections coupled together by a claw clutch which is uncoupled prior to tilting.

As shown, the liquid is supplied from a tank 7 through a pipe 8 to passage 5 which is at least 2 mm. in width and in which it is heated by supplying steam through a perforated pipe 15 to the part 12, which has insulation 17 the condensate being discharged through an outlet 18 controlled by a spring valve. Electrical heaters, hot air pipes or other heating means may replace the steam heating. The pasteurized liquid ascends through a passage 5a in which it may be cooled by circulating cold water through part 13. The vessel 4 may be in two parts the upper of which has a larger diameter so that passage 5a is of smaller width to give quicker cooling.
