Title: Control means for compensating changes in tension in the winding of wire and the like
Inventor: LESSIG DIETER
IPC: H02K15/08
Filed: 1965-06-03
Abstract: 1,067,906. Winding and reeling; making coils. ELEKTROMAT VEB. June 3, 1965, No. 23827/65. Headings B3A and B3E. [Also in Division D1] In a method of controlling the tension in wire, tape or the like during the production of non-circular windings a spring-loaded lever 1 which pivots about a point A carries a roller 5 co-operating with a fixed roller 6 to take up slack in the wound material 7 whilst means 3, coupled to the drive means of the winding machine imparts a supplementary motion to the lever 1. As shown the means 3 is a cam which moves the lever 1 in synchronism with the drive of the winding machine to compensate for variations in the rate of consumption of material. The lever 1 is made in two parts urged into line by a spring 4, and can flex to take up minor variations in tension. Movement of the lever 1 may also control a shoe brake 10 acting on a fixed guide roller 11.

Title: A transfer port assembly for elongated objects
IPC: G21F7/005
Filed: 1971-04-19
Abstract: 1,274,174. Shielded enclosures. ACIERIES REUNIES DE BURBACH - EICH - DUDELANGE S.A. ARBED, and GRADEL S.A. 19 April, 1971 [17 March, 1970], No. 23838/71. Heading B4Q. A transfer port assembly in the wall of a shielded enclosure through which an elongated object of regular convex section can be passed lengthwise comprises an air-lock 6 and two removable, supple, variable-aperture deformable seals 11, II<SP>1</SP>. The seals 11, 11<SP>1</SP> can be in the form of hyperbolical or cylindrical revolution surfaces, one normal cross-section of which is rotated with respect to another to obtain an aperture of the required diameter (Figs. 1a to 1d, not shown) or can be inflatable or elastic seals (Figs. 2a, 2b, 3a, 3b, not shown). The assembly is intended for the transfer of an elongated object, the length of which is a multiple of that of the air-lock 6, from a first enclosure 7 to a second enclosure 8, the gas pressures or contamination conditions of which may be different. To isolate the air-lock 6, removable closure assemblies 9, 10, 11, 12 and 9<SP>1</SP>, 10<SP>1</SP>, 11<SP>1</SP>, 121 are secured to the air-lock springs by means of remote locking systems 13. Each closure assembly includes a removable flange 9, 9<SP>1</SP> tightened onto the air-lock chamfered opening by means of a seal. This flange 9, 9<SP>1</SP> is fitted with a sealbearing body 10, 10<SP>1</SP> having at least one seal 11, 11<SP>1</SP>. Finally, a hinged cover 12, 12<SP>1</SP> on the body 10, 10<SP>1</SP> can statically close the transfer port assembly. The removable nature of the closure assemblies simplifies the replacement of a worn or faulty closure assembly. Conduits 15, 16 are provided for controlling the pressure in the air-lock 6. During the entire transfer process of objects which are several metres long through an air-lock of a length of only some tens of centimetres, the two enclosures 7, 8 are never in direct communication. By controlling the air-lock pressure during the different transfer sequences, one is able to direct any pressure leakages in the direction dictated by safety. If the seals 11, 11<SP>1</SP> are of the type which can be completely closed when objects are not being transferred, the covers 12, 12<SP>1</SP> can be dispensed with.

Heading D1J. An apparatus for the continuous coiling up of stock and comprising a turntable carrying at least two driven reels upon which the stock is to be wound, is characterized in that a stock severing device 8, 14 Fig. 5 is associated with each reel for severing the stock after passing from a full reel to an empty reel, and a device 8, 11 for gripping the leading end portion of the next-length of the stock after severing is completed; the severing and gripping device comprising a common lever 7 that rotates with its reel and oscillates to make cyclic severing and gripping movements during rotation of its reel before a stock end portion has been gripped and to be locked in position after severing has taken place for gripping the leading end portion of the stock. Prior to the stock being placed under the gripper-knife, the gripper knife 8 is rocked up and down once per revolution of its reel by means of a roller 15, Fig. 2, running on an annular cam 16. When stock is placed below gripper 8 the cyclic downward movement of the gripper 8 causes the stock to press down on a pawl 10 causing the pawl 10 to release a catch 9. The catch 9 is then rocked by a spring 12 such that it oo-operates with a pin 20 in a manner locking the gripper 8 in its stock-clamping setting. When a fresh supply of stock is to be coiled up a cam arrangement causes a plurality of fingers 25, Fig. 6 to rise up and a stock entry guide rises to the broken line setting to feed the stock over the fingers 25 into the annular space between the finger 25 and the reel barrel. The leading end of the stock becomes snagged by the fingers 25 and these then cause the stock to be wrapped around the reel barrel.

Title: Improvements in safety catches for automatic fire-arms
IPC: F41A17/56
Filed: 1946-08-13
Abstract: 625,274. Automatic firearms. ZBROJOVKA BRNO, NARODNI PODNIK. Aug. 13, 1946, No. 24071. Convention date, Jan. 9, 1939. [Class 119] A safety device for an automatic firearm comprises a ring 30 mounted for rotation on a tube 10 housing the recoil spring 11, this tube assisting to hold the butt 7 to the breech casing. The trigger, which pivots on a pin 23, also has pivoted to it a lever 20 and carries an extension 24 which serves to hold the breech block carrier 2 in the retracted position (shown dotted), when it is desired to insert a magazine. On pulling the trigger, this carrier flies forward under the action of the recoil spring 11 when a hammer 3 pivoted to the breech carrier 2 engages a sear 14 mounted for rotation on a bolt 8 in the trigger casing. Joined to this sear is a lever 15 carrying a tooth 16 and also mounted for rotation on the bolt 8. Further pulling of the trigger causes the lever 20 to move rearwardly and to engage a tooth 21 on its forward end in the tooth 16 of the lever 15, thereby rotating this lever and the sear 14 against the action of a spring 18 mounted in the trigger casing, thus permitting the hammer to slip past the sear to strike the firing-pin. Firing is continued until the trigger is released. With the safety device set at safe by means of a finger piece 31 the rear end of the lever 20, which is urged downwards by a spring 25, is held up by an extension 32 of the safety device thereby preventing engagement of the tooth 21 with the tooth 16 and leaving the sear 14 in such a position as to prevent the hammer 3 from striking the firing-pin.

Filed: 1922-09-11
Abstract: 205,293. Constantinesco, G. Sept. 11, 1922. Variable speed gearing; balance gearing. - Ratchet reversible gearing adapted for oscillating members of high frequency comprises an intermediate sliding member 45, Fig. 8, having large teeth 42 on one side, which have a cam function and are always in engagement with like teeth on the oscillator 41, Fig. 10, and on the other side has small engaging and disengaging teeth 43 or a gripping friction surface coacting with a rotor 44 which is driven thereby uniformly. The engaging and disengaging of the teeth &c. 43 is effected by the inertia of the ring 45 and this is assisted by a fly-wheel 46 sliding on keys on the slider 45. The forward driving, reverse, and free configurations of the ratchet are effected by sliding the fly-wheel 46 relatively to a cam pin 53, Fig. 15, which projects from the oscillator through a hole 54 in the fly-wheel. To this end, the fly-wheel is adapted to be moved laterally by a bar 50, Fig. 10, locked in proper positions by a spring bolt 51. In the application to differential gearing shown diagrammatically in Fig. 33, a balancing beam 123 mounted centrally @n driving eccentric 122 is connected at its ends by rods 124, 125 to two pairs of oscillators 126, 127 which through independent pairs of sliders 130, 131 drive part axles 128, 129.
