Abstract: 592,691. Trimming fabrics. SINGER MANUFACTURING CO. May 26, 1945, No. 13238. Convention date, July 15, 1944. [Classes 31 (i) and 42 (i)] A cloth-trimming machine having opposed rotary feed-cups for gripping and feeding the material to be trimmed, has a ledger blade mounted adjacent to one of the feed-cups with a portion of its cutting edge substantially in the plane of tangency of the feed-cups, and a movable cutting blade co-operating with the ledger blade, its cutting edge crossing that of the latter at a point lying substantially in the plane of the axis of rotation of the feed-cups. The machine has a housing 1 divided into compartments 11, 12 by a partition 10, the compartment 11 being partially filled with oil. The inner feed-cup 6, mounted on shaft 37 is driven intermittently from the main shaft 16 through an adjustable eccentric 53, pitman 54, rock-lever 50, link 49, one-way clutch 47 and gears 45, 44, while the outer feed-cup 7, mounted on shaft 60, obtains its drive from the gear 45 by means of shaft 46, and sprockets 58 and 59 connected by a clip belt 33. In order to permit the feed-cup 7 to be separated from the feedcup 6, the housing 61 which provides the journals for the shaft 60 of the cup 7 is mounted on one end of a lever 34 pivoted on shaft 113. The other end of lever 34 is connected to a control rod 130, which is in turn connected to a foot or knee control, as by a chain, while a lug 121 on the lever 34 is located between stops 122, 123, which are adjustable by screws 124, 125. A coil spring surrounding the upper end of control rod 130 presses upwardly against the lever 34, the tension being adjustable by a nut 137. A stationary ledger-blade 64 is supported on a bracket 65 secured to the lower end of the feed shaft housing 61, the end 68 of this blade being preferably of arcuate form and in register with the upper peripheral edge of the outer feed-cup 7, a portion of the cutting edge being in the plane of tangency of the feedcups. An arcuate guide-finger 69, secured to a bracket 71, is disposed opposite the ledgerblade, its edge 69<1> being preferably in vertical register with the work-engaging face of the feedcup 6, and its upper face in the same plane as that of the ledger-blade 64. A movable cutting member 73 having a cutting edge 74 preferably inclined to the plane of tangency of the feedcups, and having a finger 75 bearing upon the ledger-blade 64, is mounted on a shaft 78, prevented from turning by a collar 88 and urged downwardly by a spring 90. The bracket 77 carrying the blade mounting is continued as a shaft 91 and is given a reciprocating motion from a crank 109 formed in the main shaft 16 through a pitman 108, rock-lever 103 and link 102. An uncurling guide may be mounted in front of the feed-cups 6 and 7.

Title: Improvements in or relating to rifles
IPC: F41G1/16
Filed: 1945-05-28
Abstract: 645,751. Smallarms. BURNEY, Sir C. D. May 28, 1945, No. 13321. [Class 119] A semi-automatic recoil-shock absorbing rifle in which the barrel and bolt first recoil as an assembly against the action of a spring whereafter the bolt recoils alone, has the breech chamber of larger diameter than the breech opening through which the cartridge is introduced, and the energy stored up in the spring by the recoil of the assembly is used to impart a forward motion to the barrel assembly immediately prior to firing. In the construction shown the barrel 1 is slidably mounted in a front ring 2, Fig. 1 and a rear ring 5, Fig. 3, and between the rings extends a barrel casing 7 which is perforated for cooling purposes. The guide ring 5 is secured to the gun frame 10 and between the ring and a collar 3 on the barrel is a spring 4 which is compressed by the barrel when the barrel recoils. The barrel has an enlarged breech chamber 12, Fig. 4, and between this and the ring 5 the barrel is fitted with a rear sight 13 which can move in a longitudinal slot in the fixed breech casing 14. To the chamber 12 is screwed the front part of a breech-bolt housing 22 which is connected by a part, which is slotted to receive a magazine 21, to a housing 25 for the breech-bolt spring 29. The butt or shoulder piece 20 of the rifle is slotted to permit longitudinal movement of the magazine. The breech-bolt is made in two parts, a head 26 carrying the firing pin 33, and a rear part 27 which houses the front end of the spring 29, the head being rotatable on the part 27 against the action of a torsion spring 28. The bolt is covered by a housing 31 which is slotted to permit the retraction of the bolt handle 32, and the bolt head 26 is splined to pass through radial grooves in the breech ring. Locking of the bolt to the barrel is effected by partial rotation of the bolt after the splines have passed through the recesses. Action. To loadthe gun a safety catch 18 is moved to permit movement of a sear 15 controlled by the trigger 17, and the bolt handle 32 is first rotated and then retracted this action first compressing the bolt spring 29 and then the barrel spring 4. A bent 14a of the barrel is then held by sear 15. On releasing the handle the bolt moves forwardly carrying a round from the magazine to the chamber, and at the end of its movement the bolt head is rotated by spring 28 to lock it in position. When the trigger is pressed the assembly moves forward under the action of spring 4 until a pivoted hammer 34 strikes a fixed cam and actuates the firing pin. The assembly then recoils compressing spring 4 and during this movement a cam 36, Fig. 1, moves handle 32 to unlock the breech-bolt. The barrel is held by sear 15 and the residual pressure in the breech-chamber forces back the breech-bolt against spring 29 which subsequently moves forwardly to introduce a fresh cartridge into the , chamber, the spent cartridge case having been withdrawn by a claw-type extractor and a spring- type ejector.

Title: Semiconductor devices
IPC: H01L21/00
Filed: 1970-03-20
Abstract: 1299804 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 March 1970 [25 March 1969] 13483/70 Heading H1K Fig. 2 shows part of an NPN transistor which is symmetrical about the line MM. To increase the collector reverse breakdown voltage annular auxiliary regions 17,18 are provided of the same conductivity type as the base zone 4. (There need only be one auxiliary region-and may be more than two). As shown the floating annular electrodes 19,20 associated with the auxiliary regions 15,16 extend over both inner and outer peripheries of the junctions 17,18 formed by the regions and collector zone. They may instead extend only over one periphery or the other. Because there is a leakage current across the surface the outer periphery of each junction 17,18 is reverse biased and the inner periphery forward biased. Thus the parts of electrodes 19,20 which extend inwardly towards the base region are at approximately the same potential as the part of the collector zone adjacent the inward periphery of the associated region so that the formation of an inversion layer is prevented. However, the outwardly extending parts of the electrodes differ from the potential of their underlying parts of the collector zone in a sense corresponding to the formation of an inversion region; such an actual or incipient inversion region effectively displaces the point of maximum surface field strength away from the (disturbed) physical boundary between auxiliary region and collector zone and so increases the breakdown voltage. As shown, the base contact 8 is outwardly extended for the same purpose. To prevent channelling at the periphery of device a highly doped region 27 is provided of the same conductivity type as the collector zone and provided with an inwardly extending floating electrode 25. The collector contact 30 occupies the lower surface of the semi-conduct wafer. In a variant much of the inwardly extending part of an auxiliary electrode is removed to leave a circular rim overlying the collector zone and connected by radial parts to the main body of the electrode which extends inwardly to just beyond the inner periphery of the auxiliary junction. In a PNP transistor an inversion layer is generally present as a result of the manufacturing process and the potential on the inward extensions of the auxiliary electrodes is insufficient to interrupt it. A P<SP>+</SP> anti-inversion ring is provided close to, touching, or merged with the inner edge of an N-type auxiliary region and the PN junction between the two may be shorted out by the auxiliary electrode. Alternative shapes are possible-oval or rectangular auxiliary region and electrodes, inter-digitated emitter and base zones &c.
