Title: Improvements in and relating to automatic loading mechanisms for barrel recoil guns
IPC: F41A9/42
Filed: 1937-11-19
Abstract: 482,875. Loading ordnance. KRUPP AKT.-GES., F. Nov. 19, 1937, No. 31863. Convention date, March 12. Addition to 466,554. [Class 92 (i)] The barrel-recoil automatically-loaded gun according to the parent Specification is now provided with a movable member interposed between the entraining member of the barrel and the stop on the power accumulator, which member has two separate faces one of which takes the shock when the barrel engages with the accumulator in its return movement, while the other face serves to take the sliding movement under pressure when the power accumulator is uncoupled from the barrel. In the construction shown, the intermediate member consists of a rocking lever 102 having a front surface 104 which is adapted during run-out to engage with the stop f<4> on the cylinder F of the accumulator. The lever is pivoted at 101 to the gun barrel A and is influenced by a spring 103 which tends always to urge it to the vertical position shown. The entraining member of the barrel consists of a vertically-slidable rack 106 which is actuated by quadrant 108 pivoted to the barrel. A spring in a casing 110 tends to hold the quadrant against a stop 111. During run-out, the face 104 encounters the stop f<4>, and the barrel A and cylinder F then move together until an arm 109 on the quadrant 108 strikes a stop 112 on the gun cradle. The quadrant is thus moved in an anti-clockwise direction against the action of its spring and thereby moves the rack 106 clear of the rear face 105 of the lever 102, the lever being then rocked counterclockwise by the stop f<4> against the action of its spring. The cylinder F is held in its forward position by a locking bolt N. When this bolt is released the cylinder moves rearwardly to effect the ramming operation and the lever 102 slides off the left-hand end of the stop f<4>. When the barrel recoils the lever is rocked by the stop in a clockwise direction and, when it slides off the right-hand end of the stop, is returned by its spring to abut against the rack 106 which has been moved by its spring into its uppermost position. By lifting the rocking lever in a clockwise direction and inserting a pin through the bore 114 of a rod 113 connected thereto, the entraining mechanism may be held clear of the power accumulator.

Title: Improvements in and relating to the treatment and finishing of textile fabrics
IPC: D06M15/05
Filed: 1938-11-04
Abstract: 520,950. Treating textiles with liquids. LUMSDEN & MACKENZIE, Ltd., and GARRETT, C. Nov. 4, 1938, No. 31967. [Class 15 (ii)] Fabrics composed of cotton, linen, or other vegetable fibres are subjected to dry cleaning or treatment with a volatile liquid such as benzine, benzene, naphtha, alcohol, ether, or other solvent for oils, fats, waxes, and resins, and the fabrics which after this treatment are in a dry state are then impregnated with cellulose ethers or regenerated cellulose and scoured or bleached, mercerized or otherwise finished. The scouring may be effected prior to or after the treatment with the cellulosic solution. Treatment with volatile solvent may be effected at raised temperature and pressure. The treated materials retain a soft handle. They have increased resistance to frictional abrasion and there is less tendency to fluffing or linting of the cloth in subsequent use. In an example, cotton sheeting is dry cleaned with boiling benzine and impregnated with a solution of methyl or ethyl cellulose in caustic soda solution. After some time it is passed through a solution of hydrochloric acid and common salt. It is washed and then subjected to a lime bleaching or caustic soda bleaching treatment. It may be boiled with a solution of lime, washed, soured, boiled or scoured with soda ash solution, washed, steeped in bleaching powder solution, washed, boiled or scoured with soda ash, washed, treated with bleaching powder solution, washed, soured, washed and dried.

Title: An improved machine for folding the end flaps of catamenial napkins
IPC: A61F13/15
Filed: 1938-11-04
Abstract: 520,912. Making catamenial napkins. BURGESS, A. F. (International Cellucotton Products Co.). Nov. 4, 1938, No. 32005. [Class 81 (ii)] In a machine for folding over the end flaps of catamenial napkins, the'flaps are carried by a conveyer separate from that carrying the body of the napkin and one flap is folded by relative movement between the conveyers, the other being folded by passage under a stationary member. As illustrated the flaps 22 are carried by transverse members 21 carried by chains 19 disposed at either side of the main conveyers 12, 24, and moving at the same speed. The motion of conveyer 24, however, is periodically interrupted, and the continued motion of the members 21 carries the rear flap over the body of the pad 23 as shown in Fig. 8. When the motion of conveyer 24 is resumed the forward flap, which has been deposited by the members 21 on the fixed element 47, is folded by the passage of the pad under this element. A reciprocating arm 56 holds the pad while the rear flap is folded and then rises to permit it to proceed. The mechanism is suitably incorporated in a machine of the type described in Specification 367,000.

Title: An improved method of and apparatus for manufacturing paper containers
IPC: B31B50/62
Filed: 1935-11-19
Abstract: 445,824. Manufacturing paper containers. JAGENBERG-WERKE AKT.-GES., 107, Himmelgeisterstrasse, D³sseldorf, Germany. Nov. 19, 1935, No. 32024. Convention date, Nov. 20, 1934. [Class 18] Paper containers with a glued longitudinal seam and enlarged at the top, made, e.g. from blanks m, Fig. 1, and ends b on rotating formers d, are kept nested in a magazine T which applies pressure to the seam N, Fig. 5, until the glued joint is consolidated, after which the container is withdrawn for further treatment. The containers may be blown into a pipe r by compressed air and removed by grippers which deposit them in cells z of a chain k. The pile S of containers resting on a plate e, Figs. 3 and 5, is gripped by strips 13 with rubber coatings g carried by a fixed support 8, Fig. 5, a spring-actuated lever 10 hinged to the support 8 and controlled by a roller 12 on a lever 6, Fig. 2. mounted on a shaft 1, also carrying a presser strip 13. A cam 5 on a shaft 4 actuates a lever 2 on shaft 1 to control lever 6 to grip and release the containers. The containers are kept from falling out by a stop 16 carried on one arm of a lever 15 the other arm of which carries a roller 17 actuated by a cam 18 on shaft 4. Gripping the containers. A further cam on shaft 4 controls an oscillating arm 20, Fig. 2, by a connecting rod 22, a lever 23, and a roller 24. The spring gripper 21 is carried by arm 20 and is opened by moving a lever 25 by cams 26b, 26a on a lever 27 pivoted on a shaft 14 and controlled by a cam 29 on shaft 4 which contacts a roller 28. The gripper is closed when released from can 26a by a spring (not shown). The timing is such that stop 16 moves aside in time to allow gripper 21 to grip the lowermost container, the penultimate container being gripped by the pressers 13. When the gripper has withdrawn, carrying the container, stop 16 moves upward and lever 6 is actuated to release the pressers 13 so that the pile slides down to the stop, the pressers then again coming into action. The gripper conveys the container to a cell z of a chain k, and is opened by cam 26b and thereafter swings back through the next vacant cell of the chain. Meanwhile cams 26a, 26b move down so that the gripper is opened by cam 26a preparatory to the next cycle. Adjusting the length of the stack. If the stack becomes so short that the time the container is in it is inadequate for the consolidating of the glued seam, a feeler F, Fig. 7, no longer contacts a container and moves to actuate a ratchet 32 by a lever 30 and spring 31, so that a rod 33 on lever 27 is inhibited from movement by the ratchet 32 and the movement of the gripper is stopped until accumulation of containers in the stack releases feeler F and the ratchet 32 is withdrawn by spring 31.

Abstract: 467,667. Valve circuits for wireless reception. PERCIVAL, W. S. Nov. 20, 1935, No. 32231. [Class 40.(v)] In a super-regenerative receiver the quenching oscillation is such that between the oscillation and quenching periods a state corresponding substantially to critical reaction is maintained for a substantial portion of the quenching cycle. The Figure shows a super-regenerative valve 5 associated with an aerial circuit 3, 4 and quenched by an oscillator 13 which operates as a relaxation oscillator of the blocking oscillation type controlled by the grid condenser 15 and resistance 19. The trains of oscillations are detected by diode 27 shunted by a radio frequency choke 28 and a circuit 29, 30 tuned to the quenching frequency. Oscillations of the quenching frequency are amplified by the valve 31 and detected by a second diode detector 36 connected to the low frequency amplifier through a quench frequency choke 37. Additional tuned circuits in the receiver may be separately quenched or may be provided with additional damping 'by thermionic discharge devices which may be controlled by the quenching oscillations. The quenching oscillation preferably has a wave form with a flat top, the Specification gives curves of suitable waveforms for use as the quenching oscillation. Specification 467,732 is referred to.
