Abstract: 1,136,362. Single shot, drop breechblock rifle. STURM, RUGER & CO. Inc. 15 May, 1967 [16 May, 1966], No. 22388/67. Heading F3C. A single shot, drop breechblock rifle comprises a receiver 1, a drop breechblock 8 in the receiver 1, a hand lever 4 pivotally mounted on a pin 5 in the receiver and a hammer 12 pivotally mounted on the pin 5. An intermediate member 14<SP>1</SP> is also mounted on the pin 5 and cooperates with the hand lever 4 through a toggle linkage 30 and the hammer 12 through a shoulder 14. The intermediate member 14<SP>1</SP> is also provided with a lever arm 26, a lug 25 of which co-operates in its movement with cam faces 27, 28 of the breechblock 8. Initial movement of the breechblock is caused by the cooperation of a surface 40 thereof with a surface 29 of the lever arm 26. Movement of the intermediate member 14<SP>1</SP> cocks the hammer 12 which is then held in its cocked position by a spring-loaded, pivoted sear 97 (Fig. 2), the hammer being spring-loaded by a strut 20 and spring 21. The hammer energy is transferred to a firing-pin 19 through a pivoted striker 16 adjustably positioned in contact with the firing- pin 19 by a limit screw 18. A safety 102 is provided, the safety having a depending lug 114 which, in the safe position, blocks the end 113 of the sear 97. An additional safety means comprises a link 120 co-operating with a notch and a surface 112 of the safety through a stud 122 such that, when the safety is in the safe position, the link 120 urges a bar 126 into engagement with the hammer 12, the pressure between the bar 126 and hammer 12 being such that the hammer is disconnected from the sear 97 (Fig. 3, not shown). A cartridge ejecting mechanism comprises an ejector 45 (Fig. 8) pivotally mounted on the pin 5 and co-operating with the rim 50 of a cartridge 11 to which position it is urged by a spring (Fig. 11, not shown). The ejector 45 is mounted on the pin 5 such that it can pivot about the axis of the pin and in the direction of the axis of the pin. The ejector 45 is actuated by an over-centre spring-loaded actuator 54, an ejector cam 55 of which engages with one face a bearing surface 75 of the ejector 45 and with another face an end 74 of the hand-lever 4. Movement of the hand lever 4 pivots the cam 55 and hence the ejector 45 until the actuator passes its centre whence the cam is rapidly pivoted to snap rearwardly the ejector 45 to eject the cartridge. The spring loading of the actuator 54 may be dispensed with whereby the cartridge is ejected at the speed of movement of the hand lever 4. A roller 76 on the breechblock 8 urges the ejector 45 into its cartridge engaging position on movement of the breechblock into the firing position.

Abstract: 650,933. Preparing fibres for spinning. PLATT BROS. & CO., Ltd., and MARSDEN, I. July 27, 1946, No. 22425. [Class 120(i)] [Also in Group XVIII] An automatic weighing and feeding machine supplying textile fibres to carding engines and of the kind in which means are provided for interrupting the feed to the scale pan when a predetermined "weigh" has been delivered thereto and prior to timed periodic actuation of the scale pan for releasing the "weigh" therefrom, and having electric switch means associated with the pan for actuation on movement of the pan when the "weigh" has been fed thereto, mechanism being brought into operation by the switch means for interrupting the feed to the pan, is characterized in that the switch means comprises a mercury switch attached to and moving with the scale beam and a solenoid in the switch circuit arranged for direct actuation of catch release mechanism forming part of the means of interrupting the feed of material to the pans so as to effect such an interruption on downward movement of the pan. The longitudinal spring- biassed doors 11, 11a of the scale pan hinged at 12, 12a are opened by a weighted bell-crank lever 23a bearing upon a pin 15 attached to the arm 14c and engaging in a slot in the arm 14b of the bell crank levers 14, 14a which are fixed to the door pivots 12, 12a. The lever 23 is operated by a cam 27 which is driven continuously. The scale pan is pivotally attached to weighted arms 18 to which is attached a mercury switch 18b. When the scale pan has received a predetermined "weigh," the arms 18 tilt and operate the switch 18b which energizes a solenoid 56 to pull a link 54 to turn a weighted lever 52 and remove a catch 57 from a shoulder on an axially movable rod 50 to allow the same to move a belt fork to shift a belt 67 from a fast pulley 68 to a loose pulley 69 and stop the feeding lattice 51. At the same time a trap door (not shown), above the scale pan is closed to prevent additional material from entering the pan. The rotating cam plate 27 now brings cam 27a to operate the bell crank 23 to open the doors 11, 11a of the pan to deliver the "weigh" on to the lattice 74. The scale pan now rises under its weight 21, 21a and cam 27b then operates a bell crank 43 which through a link 45 will move an arm 46 to bring a bowl 47 against the underside of the scale arm to prevent rebounding of the arm. At the same time the switch 18b is disconnected, the solenoid de-energized and the lever 52 moves to press the catch 57 on to the rod 50. The cam 27 then slides the rod 50 axially to move the shoulder thereon behind the catch 57 and so move the belt 67 on to the fast pulley 68 to operate the feed lattice and open the trap door (not shown), for another "weigh" to be delivered into the pan. Specification 281,470 [Class 120(i)] is referred to.

Title: Improvements in or relating to methods of and apparatus for color reproduction
IPC: H04N1/60
Filed: 1937-08-24
Abstract: 506,259. Copying by scanning. INTERCHEMICAL CORPORATION. Aug. 24, 1937, Nos. 23218 and 23219. Convention dates, Sept. 4, 1936 and Jan. 21, 1937. [Class 40 (iii)] [Also in Group XX] In a method of colour reproduction a colour separation image is used in which the effect of light in one spectral region is subtracted from that in another spectral region. In one method of producing the colour separation image, the two records are scanned in an apparatus having photoelectric cells in a circuit arranged so that the currents passing from the cells are opposed and a control device which produces a record from the resulting current. The colour separation image may also be produced from more than two records, e.g. from three records adapted for use with theoretical primaries, mixtures of which will produce all possible colours. Fig. 5 shows an apparatus for carrying out the process electrically. The original records are mounted on the scanning drums 10A, 10B, 10C, illuminated by the light sources 12A, 12B, 12C, which may be adjusted by the rheostats 14A, 14B, 14C, and scanned by the photoelectric cells 17A, 17B, 17C, the currents passing through which arc combined by means of the reversing switches 21A, 211; 21C, which enable any one current to be opposed to the other two. The resulting current is fed to the light valve 23 and controls the intensity of light falling on a drum 10X, rotated in synchronism with the drums 10A, 10B, 10C. The resulting colour record images are stated to give more accurate colour reproduction.

Title: Improvements in devices for feeding sheets, envelopes and the like to addressing and like printing machines
IPC: B65H1/02
Filed: 1936-08-24
Abstract: 475,601. Feeding sheets. ADREMA MASCHINENBAUGES. Aug. 24, 1936, Nos. 23249 and 23250. Convention dates, Aug. 23, 1935 and July 11, 1936. [Classes 100 (i) and 100 (ii)] A sheet-feeding device, which is more especially applicable to addressing- machines, is constructed so as to deal with sheets, envelopes, &c. of different thicknesses, the pile 21 of sheets being arranged on edge in a magazine 7 formed with apertures in the bottom 8 and front side 9 which terminate in edges 8<1>, 9<1>. The separation of the sheets is effected by means of a pair of friction rollers 14 formed with rubber friction pads 17 which are secured to stepped parts 16 of the rollers and may be formed with projections 20. To prevent the separation of more than one sheet at a time, the edges of the foremost sheets rest on a resilient bar 29 having a facing of sandpaper or similar material, the bar being carried by a metal strip 27 which is adjustable along a bar 26 secured to the bottom 8 of the magazine. The bar 29 is carried by a plate 30, which together with a stop 32 having a projecting end 32<1> for limiting the downward motion of the bar 29 are adjustable longitudinally relatively to the strip 27 and are secured in position by a screw 33. For thin papers the bar 29 is moved near to the peripheries of the rollers 14. Separation of one sheet only at a time is assisted by an adjustably mounted presser plate 39 which is carried by a bar 36 adjustably mounted in a holder 35 carried by a cross-bar 34. A screw 41 presses the plate 39 against the pile, and the plate is set close to the bottom 8 for thin sheets and further away for thick sheets. The separated sheet is advanced to the printing position 2 by rollers 22, 23, and guides 25 co-operating with the rollers 14, and by conveyer bands 3 driven by the rollers 4 and weighted rollers 5 co-operating with the conveyer bands. The apparatus may be fitted with an electrically controlled device for stopping the addressing-machine and feeding mechanism, if a sheet is not fed or delivered correctly. Adjustably mounted feeler devices 55, 56, Fig. 5, which are carried by bars 49 with capacity for rough and fine adjustment, are arranged above electric contacts 57, 58 which are insulatedly mounted. The sheets or envelopes normally prevent contact between the feelers' and the contacts 57, 58, but if a sheet is missing a circuit is completed to an electromagnet, and the energization of the magnet attracts an armature which releases a spring-impelled lever 71 normally restrained by the armature, and the lever 71 operates the wire core of a Bowden control which is caused to operate means for stopping the addressing- machine in known manner. The circuit of the electromagnet includes a low-voltage battery and also a switch operated by a cam on the shaft 11 which keeps the circuit open except for a short part of each revolution of the shaft 11.
