Title: Improvements in paper folding machines
IPC: B65H45/16
Filed: 1960-09-02
Abstract: 912,028. Folding paper. WOOD NEWSPAPER MACHINERY CORPORATION. Sept. 2, 1960 [Nov. 13, 1959], No. 30349/60. Class 100 (1). A rotary paper folder comprises drive means connected by a first gear train to the folding cylinder 3 for rotating it, a folder blade drive shaft 5 rotatably mounted in the cylinder and extending parallel to the longitudinal axis of the cylinder, a second gear train connecting the shaft 5 and the drive means, and means for rotating the shaft 5 in relation to the drive means and the cylinder while the cylinder is rotating. The shaft 5 is eccentrically mounted in the bearings which support the cylinder 3 and has brackets 6, 7 mounted thereon. Shafts 10, 11 are rotatably mounted in the brackets 6, 7 and carry folder blades 12 which at the appropriate time project through circumferential slots in the cylinder 3 to fold sheets cut from a web by a cutting cylinder 4 into the nip of a pair of folder rollers. The shafts 10, 11 are rotated in the brackets 6, 7 by means of pinions 13, 17 (Fig. 2, not shown), which mesh with idler gears 14, 18 which in turn engage gears 15, 19 non-rotatably mounted within the cylinder 3. As the brackets 6, 7 are rotated by the shaft 5 the shafts 10, 11 are driven. A gear on the main drive-shaft of the machine meshes with a gear 49 secured to the cylinder 3 for rotating the latter. The shaft 5 is driven by means of a gear 21 rotatably mounted on one end thereof which meshes with a further gear on the main driveshaft of the machine. An internally-toothed annulus 24 having helically cut teeth is secured to the gear 21 and meshes with an internally and externally helically-toothed annulus 26 journalled in a bracket 27 mounted on an antifriction bearing 28 so that the bracket and annulus 26 are free to rotate about a worm 29. The internal teeth of the annulus 26 mesh with a helical gear 25 fixed to the end of the shaft 5. Thus the drive to the shaft 5 is transmitted through the gears 21, 24, 26, 25. Movement of the annulus 26 longitudinally of its axis causes relative rotation between the annulus 24 and the gear 25 whereby the moment at which the folder blades 12 project from the cylinder 3 may be adjusted so as to take account of variations in web speed. The worm 29 is moved longitudinally to effect this by rotation of a gear 30. The gear 30 is rotated by means of an electric motor 34. U.S.A. Specification 1,784,757 is referred to.

Abstract: 650,883. Protective arrangements. GENERAL ELECTRIC CO., Ltd. Nov. 15, 1947, No. 30392. [Class 38 (iv] [Also in Group XX] Apparatus including a housing, a source of radiant energy, a number of filters or like members, each of different density and each capable of being inserted into an operative position within the housing, a corresponding number of electric circuits each adapted to co-operate with a different filter or like member, each circuit including a switching means, each filter, or means carried by each filter, forming part of the electric circuit corresponding to the particular filter or like member, is characterized in that energization of the source of radiant energy may only be effected by operation of that one of the switching means in the circuit associated with the selected filter or like member. As shown, in apparatus for X-ray therapy in which any one of a set of four filters may be used, a holder 3 is provided on the X-ray head to receive the filter 1, which fits in the holder in one way only. The filters each have a projection such as 4 which makes contact with one of the contacts 5-8 on the head, the particular contact depending on the position of the projection on the filter fitted. The contacts are connected to a series of signal lamps 25-28 and to a series of push-button switches 15-18, which remain closed only when pressed. Current is supplied from terminals 12, 13 to a relay 9. A door providing access to the filters carries a contact 11 which is closed only when the door is closed. When a filter has been inserted, and the door and contacts 11 closed, the push-button corresponding to the filter inserted (16 in the example shown), is pressed. A circuit is made from terminal 12 through contact 11, switch 16, contact 6, the metal frame of the filter carrying projection 4, and an earth return to terminal 13. This energizes relay 9 closing (1) contacts 19, making a holding circuit ; (2) contacts 21, completing the circuit of signal lamp 26 ; and (3) contacts 20 in the X-ray tube contactor coil circuit. The X-ray tube can be switched on only after contacts 20 are made. If the wrong filter is inserted, or the wrong button is pressed, the relay circuit is made through two signal lamps, whose combined resistance is too great to allow sufficient current to flow to operate the relay.

Abstract: 704,837. Firearms. OLIN INDUSTRIES, Inc. Dec. 1, 1952 [Dec. 18, 1951; Dec. 18, 1951]. No. 30434/52. Class 119 A firearm comprises a chamber member 2, in connection with a receiver 1, constructed to contain the explosive force of the round to be fired independently of the barrel 4, the barrel being mounted over the chamber member and connected thereto, and the chamber member having a neck portion 10 which can expand into sealing contact with the barrel under the pressure of the explosion. In one construction the chamber member 2 is secured to the receiver 1 by an interrupted-screw portion 8, and is screw-threaded at 3 for the connection of the barrel 4. A flange 6 on the member 2 provides abutment faces for the receiver and barrel. The member 2 is of high strength metal, such as nickel steel, nickel-vanadium steel, stainless steel, or beryllium-copper alloy so that it can withstand, without rupturing, the gas pressure developed on firing. The neck portion 10 is thin-walled so that it expands on firing into sealing contact with the barrel. The barrel is of light material such as aluminium alloy, magnesium alloy, or titanium and its alloys. As an example a barrel of aluminium alloy has an outer and inner coating of pure aluminium, and this may be anodized both inside and outside. In a modification, Fig. 3 (not shown) the chamber is integral with the receiver and has half-threads for the connection of the barrel which, when in place, is secured to the receiver by a set. screw. In another construction, Fig. 4 (not shown) fine full screw threads connect the chamber to the receiver, and half threads connect the barrel to the chamber.

Filed: 1962-08-09
Abstract: 985,243. Magnetic amplifier circuits. W. BROOKE, and H. HOWE. Aug. 9, 1962, No. 30526/62. Addition to 864,714 and improved upon by 943,205. Heading H3B. The application of current from an A.C. supply L1, N to a load M1 is controlled by a main transductor C as described in the parent Specification, and the load circuit is shunted by an auxiliary transductor GR arranged to be energized when the main transductor is de-energized and vice versa, the auxiliary transductor excitation being derived either from a transformer winding 10, 11 on the main transductor core or from a transformer (not shown) connected across the main transductor. To energize the load, isolating switch V is closed and push-button K depressed so as to open contacts 30, 31 and disconnect the control windings GR1e, GR2e of the auxiliary transductor from the output of transformer windings 10, 11 which is rectified at F. A circuit is also made at push-button contacts 32, 33 to cause the main transductor to be energized from a transformer winding GR1s, GR2s on the auxiliary transductor which changes to a high shunt impedance as its energization is removed, the main transductor energization being applied to control windings 6-9 by way of rectifiers H and U. The load current is terminated either by an overload relay Z opening contacts 43, 44 or by depressing a push-button J, both causing the main transductor energizing circuit to be opened. Due to increased impedance of the main transductor, an energizing current is obtained from rectifier F sufficient to saturate the auxiliary transductor. A three-phase arrangement is also described, Fig. 2 (not shown). Specifications 900,196 and 943,204 also are referred to.

Filed: 1929-10-14
Abstract: 331,159. Maschinenfabrik Augsburg- Niirnberg Akt.-Ges. Oct. 13, 1928, [Convention date]. Tripping-arrangements.-In a printing-machine of the kind which is tripped automatically if the sheet-feed fails, and is restored automatically to printing position upon re-establishment of correct feed, the tripping and untripping motions are controlled by electromagnets 14, 22 so arranged that the circuit to the magnet 22 is made by the tripping motion due to the energization of magnet 14. The magnet 14 attracts an armature 15 on a lever 16 formed with a guide 18 which controls a pawl 9 on a freely-mounted lever 10 oscillated on a shaft 8 by lever mechanism from a cam 13 on the shaft of the impression cylinder 1. The pawl 9 is thus made to engage a shoulder 21 of a recessed disc 7 fixed on shaft 8, and this shaft 8 is moved clockwise to rotate, via arm 6 and trip rod 5, the eccentric bearings in which the printing-cylinder 3 is mounted. The energization of magnet 14 takes place if a sheet fails to be fed over the table 2. Normally the sheet prevents contact of an oscillating contact 28 with a fixed contact 29, and if the sheet is absent the contacts 28, 29 complete a circuit from one main 27, through contact arm 26, contact 25, magnet 14, and contacts 28, 29 to the other main 30. The rotation of shaft 8 to tripping position completes the circuit to the magnet 22 from. main 27, arm 26, contact 31, contacts 32, 34, and contacts 35, 36 to contact 29, thence to main 30. This circuit is only closed during a part of the rotation of the impression cylinder. The magnet 22 although it is energized does not move its armature 23 until the magnet 14 is de-energized by the breaking of its circuit due to the passage of a sheet between the contacts 28, 29. The pawl 9 is then operated by lever 16 to engage the shoulder 24 of the recess in disc 7, and thus reverse the shaft 8 to throw the printing members into printing position. The lever 26 instead of engaging both contacts 25, 31 can be made to engage the contact 25 only if it is desired to keep the forme cylinder permanently tripped, or the contact 31. only if it is desired to keep the cylinders permanently in printing position. The invention is especially applicable to multi-colour machines by fitting each set of a. multi-colour machine with a tripping mechanism as described.
