IPC: D05B29/06
Abstract: 106,661. Fairweather, W., (Singer Manufacturing Co.). May 30, 1916. Sewing-machines; feed by doq.-To prevent stretching in sewing elastic materials, a work-retarding member is provided at the rear of the needle and co-acts with the presser-foot to friction slightly and retard the material in opposition to the feed movements of the feed-dog. The invention is described as applied to a cylinder-bed machine in which the work is fed up the worksupporting arm, and in which the single workadvancing feed-dog 25, Figs. 1 and 3, is adjustably secured to the channelled forward portion 28 of the feed-bar 29, which derives its lengthways reciprocatory movements from a bell-crank comprising a sleeve 43 having an arm connecting to the feed-bar and an arm 42 connecting with a strap embracing an eccentric 37 on the main shaft 7, and its lifting movements from a sleeve 31 which is pivoted between the bifurcated end of a rod 34 having a strap 35 embracing an eccentric on the reduced extension 7' of the main shaft. The work-retarding element comprises an angle-lever 65 pivoted at the bend 67 to a curved bar 69 secured to the work-support and provided with two forwardly-extending arms 64 with workengaging elements 63, which are adapted to pass through the apertures in the workplate provided for the outer members of the feed-dog. An arm 66 of the lever is connected by the link 72 to the arm 74 of a bell-crank lever comprising a sleeve 75 pivoted on a pin 76 and having another arm 78 connected to a treadle by a spring 80 and chain 81. To retard the work at the rear of the feeding-elements and prevent stretching of the material, the treadle is depressed and causes the work to be lightly clamped between the elements 63 and the presser-foot. The movement of the lever 65 is limited by an adjustable stop 82. Presser-feet.-The presser-foot 56, Fig. 4, is pivoted at 54 to lugs 53 on a block 52, which in turn is pivoted by a pin 51, at right-angles to the pivots 54, to the shank 50, and may be provided with a rib 57.

Abstract: 688,357. Projectile fuzes. MEFINA SOC. ANON. May 9, 1951 [May 20, 1950], No. 10874/51. Class 9(i) A projectile fuze is provided with safety means preventing arming of the fuze until the projectile has left the gun. The fuze has a body 1 in which is axially mounted a firing pin 2 having an annular flange 3 on which rests a sliding member 4, forming selfdestruction means. influenced bv a spring 5. Radial bores 7 in the sliding member accommodate plungers 8 bearing against a conical surface 9 of a socket 10. Below the socket is a hollow member 11 with an opening 12 for the passage of the firing pin. The wall of the recess 13 in the member 11 follows a spiral with the axis of the fuze as centre. To one side of an opening 14 in the wall is a stop 15. Within the recess, beneath the flange 3 of the firing .pin are balls 16 preventing the firing pin coming into contact with a primer 17. On firing the projectile. while in the barrel of the gun the balls 16 are held within the recess 13, the last one bearing against the stop 15, and the opening 14 being closed by an annular blade spring 19 in a recess 18 surrounding the member 11. Under centrifugal force the spring 19 expands and moves outwards to the wall of the recess 18. Centrifugal force acting on the plunger 8 causes the member 4 to move axially and so compress the spring 5 thereby removing the load from the flange 3 of the firing pin. On leaving the gun, angular acceleration of the projectile ceases and the balls 16 are caused by centrifugal force to follow the spiral path formed by the wall of their seating and pass through the opening 18 into the recess 14. The fuze is then armed so that on impact or under the influence of the self-destruction means 4 the firing pin 2 strikes the primer 17. Specification 653,547 is referred to.

Fig. 3 shows a dispatch/receiving station of a branch tube BT connected by diverter D to a tube T. Carriers are entered through aperture 16 actuating microswitch 19, carrier receptacle 17 is movable into communication with branch tube BT for dispatch, actuating microswitch 18 when in correct alignment. Switch 21 feeds the address of the receiving s ation into the station circuit (shown in Fig. 5) and thus into the control circuit via line 26, inhibiting information entering input side of line 26 until the following scan of the control circuit. The control circuit operated the pump and diverters on receipt of the signal and continues to scan the station circuits while the carrier is being conveyed so that information about a subsequent carrier is available to actuate the system as soon as the conveyance of the first carrier is terminated.

Abstract: 550,036. Electricity supply systems. STONE, & CO., Ltd., J. Aug. 29, 1941, No. 11037. Convention date, May 13. [Class 38 (iv)] Variable-speed generators, with boosting by dynamo-electric machines.-A motor 20, connected across a variable voltage switch 11, 11a and arranged to run at constant speed, drives a boosting generator 24 in series with the source, and the field of the booster is caused to vary inversely with source variations whereby a constant voltage output 14, 28 is produced. Fluorescent lamps may thus be run at 60 or 80 volts from a variable-speed generator and battery system 2, 12 giving voltages varying between 28 and 45 volts. Rapid starting is provided by a series winding 19 on the motor which is subsequently counteracted by load current in a winding 51. The main motor field is composed of windings 17 in series with non-linear resistances 42a - d wherein increase of voltage causes a fall in resistance so that the motor field increases with applied volts and the speed remains constant. The booster has a series field 23, a constant current field winding 25 energized by the output voltage through a stabilizing ballast lamp 36, and a field winding 27 opposing the others and comprising a non-linear resistance as aforesaid whereby the boost volts fall as the source volts rise ; the field 27 may be in series with the motor field 17 and may be in a separate circuit with its own non-linear resistance. The resistances 42a - d are secured in positions on the booster such that their negative temperature coefficient compensates for temperature changes.

[Class 7 (iv)] [Also in Group XXXVI] A bushing 19 of copper or other good heat-conducting metal and a metal hoop 22 of low conductivity are compressed by swaging about the electrode 14 and mica insulating wrappings 17. Both members are flanged, the surface of flange 20 being shaped to lie against an internal shoulder in the casing. The members 19, 22 are internally expanded before assembly on the insulation. A sealing agent is applied to the overlapping edges of the mica wrapping. The central electrode 14 is of low or negligible conductivity, and heat transmission to the outer end of the plug is reduced by boring out the electrode. The sparking terminal 15 may be integral with or attached to the stem 14 which may be coated with a material of greater heat emissivity. Before lateral compression of the members 22, the whole assemblage of the electrode, bushings, insulations and cap 25 is axially compressed and the end 28 turned over. The inwardly curved end 8 of the casing is radially slotted leaving a partly annular spark-gap. A shielded coupling for preventing highfrequency emission consists of a metal tube 33 and insulation 37, 38 beaded at one end for engagement with a metal union 35 screwed on to the plug gland-nut. The insulation encloses a threaded bush 40 through which passes a pointed screw 41. Spiral springs 42, 46 make electrical connection with the nut 25 and exposed end 44 of the cable. Overheating of the insulation 45 is avoided by forming ribs 39 in the insulation 38 for allowing air to circulate.
