Title: Improvements in and relating to apparatus for handling strip material
Inventor: KANNO TADAAKI
IPC: G03D13/00
Filed: 1968-10-18
Abstract: 1,205,679. Feeding webs. RICOH K.K. 18 Oct., 1968 [21 Oct., 1967], No. 49599/68. Heading B8B. [Also in Division G2] Apparatus for feeding strip material, having an initial set therein, to a device such as a copying apparatus which requires the material to be without curl includes means for imparting a corrective set to the material, the means being coupled to the feed mechanism for the material so as to be rendered inoperative when the feed mechanism is not operating so that an unwanted set, in the opposite sense of the initial set, is not imparted to the material if the feeding apparatus is left inoperative for a relatively lengthy period. As shown, a photo-conductive paper strip passes from a roll 1 over a guide roller 2 to a pair of feed rollers 4, 4<SP>1</SP>, roller 4 being permanently engaged by a brake (not shown) to prevent over-running of the roll 1, and then to a cutting device 5, 6 from which sheets of paper are fed to an electrostatic charging device 8 and thence by rollers 9, 9<SP>1</SP> to copying apparatus (not shown). Mounted between the rollers 2 and 4 is a set-modifying device including a bar 3 which can be rotated from an operative position, defined by a stop 11, in which it engages the paper and imparts a set thereto, to an inoperative position, defined by a stop 12, in which it disengages from the paper. A lever mechanism (Figs. 2 to 5, not shown) controls the angular position of the bar 3 and is associated with the feed roller 4 so that the bar is disengaged from the paper when the feed stops.

Title: Vapour pressure-reducing valve with a rapid opening devic
IPC: F01D17/14
Filed: 1975-12-03
Abstract: 1527737 Stroke adjusting BOCHUMER MASCHINENFABRIK ARTHUR SCHNEIDER 3 Dec 1975 [1 March 1975] 49671/75 Heading F1D [Also in Division F2]  In a vapour pressure-reducing valve for use in the by-pass of a steam turbine a hydraulic/pneumatic diaphragm device 6 acts on a valve stem 2 via a spring 7 to position the stem according to pressure and temperature on the low pressure side of the valve and a hydraulic/pneumatic diaphragm device 5 gradually closes the valve during turbine start-up, which movement compresses spring 7, and biases the valve closed during turbine running. If the turbine is to be rapidly shut-down the device 5 is relieved so that the valve moves under the loading of spring 7 to the regulating position set by the device 6. The device 6 may be double-acting or single-acting biased by a spring.

Abstract: 1406349 Locking devices ISRINGHAUSEN Gebr 25 Oct 1973 [28 Oct 1972] 49713/73 Heading E2A In a vehicle seat having a seat frame 4 mounted on an under-frame 7 so as to be able to oscillate relative thereto a locking device for locking the seat relative to the under-frame includes a stop bolt 9 attached either to the seat frame or the under-frame, and a hook 8 pivotally mounted on the underframe or the seat frame respectively. The hook is pivotable into two end positions in one of which it engages with the stop bolt and in the other of which the stop bolt is freely movable, the hook being held in the two end positions by a tension spring 15 which is attached at one end to the underframe and at the other end to the hook in such a way that the two points of attachment lie in a plane at a right angle to the pivot axis 10 of the hook, and the points of attachment of the spring are arranged on opposite sides of the pivot axis. The point of attachment of the spring to the under-frame is mounted so as to be movable between two end positions lying on opposite sides of a plane containing the axis 10 and the point of attachment of the spring to the hook. As shown, the hook has noses 13, 14 which can abut the underframe to limit movement of the hook to the end positions thereof, the spring 15 'being attached to the end of a lever 19 mounted on the pivot bolt 10 of the hook and the ends of the two arms of which provide limiting stops for abutment with the underframe. The attachment point 18 of the spring is moved along an arc about the axis of the bolt 10 by a lever 23 pivoted at 24 to the under-frame whereby the hook may be engaged with or disengaged from the stop bolt 9. In Fig. 2, the lever 20 is operated by a handle 21 which extends through an arcuate slot 22 in the under-frame. In a modification, the point of attachment of the spring to the under-frame is moved by a cable or an electromagnet.

C. voltage supply to a television camera is compared with a saw-tooth reference voltage in order to control the switching of a triac in the supply circuit. In the circuit shown, a camera 6 is supplied over a bridge rectifer 3 and triac 9 with a parallel capacitor 30. Supply cables 5, 11 may be of variable length. The voltage across the camera is fed to inputs 16a, 16b of an operational amplifier 16 using a Zener diode 17 and resistor 18 for matching. A saw-tooth voltage, derived from rectifiers 20, 21 and an integrating circuit 23, 24, 25, is also applied to input 16a to provide a reference, so that when the sawtooth voltage reaches the potential at input 16b, the amplifier 16 produces an output pulse to turn on the triac 9. A resistor 32 increases the linearity of the control characteristic. In another embodiment, Fig. 2 (not shown), the bridge rectifier 3 is replaced by a centre-tapped rectifying arrangement, the supply transformer 1 having only a single secondary winding.

Abstract: 1,097,307. Syringes. F. LINDER. Dec. 21, 1964 [Dec. 21, 1963], No. 51781/64. Heading A5R. A syringe for the injection or withdrawal of fluids comprises a flexible bag for the fluids, the bag being subjected to an excess gaseous pressure or reduced gaseous pressure depending on whether fluid is to be ejected from or sucked into the bag. In one embodiment (Fig. 2) the syringe comprises a flexible bag 4 surrounded by rigid member 1 to which is connected a hand compressible member 5. The member 1 has an aperture 6 which may be closed by the hand or a manually operated valve 7 may be provided to close or open the aperture 6. The cannula 3 may always be in communication with the bag 4 or brought into communication with the bag 4 prior to use, by piercing diaphragm 9. The pressure on bag 4 may be increased to eject fluid by closing aperture 6 and compressing member 5, or decreased to withdraw fluid by closing aperture 6 and allowing the compressed member 5 to expand due to its own elasticity. In another embodiment (Fig. 5) the bag 4a in a filled condition, is in a sealed chamber 11 of container 1, the chamber 1<SP>1</SP> being under excess pressure (or vacuum if the syringe is to be used for withdrawing fluids). The container 1 has an antechamber 30 under vacuum. The container is telescopically mounted in sleeve 21. In use the cannula 3 is inserted into the body and the container 1 is inserted into sleeve 21 till the cannula 3 punctures sealing washer 17 and enters chamber 30. Due to the vacuum in chamber 30 fluid is withdrawn into the chamber 30 and if this fluid shows that the cannula 3 has-been correctly inserted in the body, the container 1 is further inserted into the sleeve 21 till the cannula 3 punctures diaphragm 16 and communicates with the bag 4a. Due to the chamber 1<SP>1</SP> being at excess pressure fluid in the bag is injected into the body. The sleeve 21, container 1 and bag 4a are made at least partially of a transparent material.
