Title: Actuating arrangement for two clutches in a reversing gea
IPC: B60K23/02
Filed: 1975-09-12
Abstract: 1485703 Reverse gear control DEERE & CO 12 Sept 1975 [13 Sept 1974] 37620/75 Heading F2D A single pedal 47, Fig. 6, selectively actuates forward and reverse clutch levers 30, 32, on an agricultural tractor or combine, through an actuator 36 arranged between the levers and including a lock-out device which, each time the pedal is depressed beyond the range for normal clutch release, indicated to the operator by increased resistance, changes the lock-out device from one clutch lever to the other. Surrounding the piston-rod 38 of an hydraulic actuator 36, energized by the clutch pedal 47, is a lock-out sleeve 46 the outer end of which has slots 48, Fig. 8, one of which admits the operative clutch lever, e.g. 32, to permit engagement of that clutch on pedal release, whilst the other lever 30 is held in the disengaged position by one of the abutments 50 between the slots 48. On depressing the pedal 47 beyond the range for normal clutch release, the piston 38, opposed by a spring 64, takes the lock-out sleeve 46 axially along to the position shown in Fig. 6, and the sleeve, during this movement is also turned through a half-pitch of the slots 48 by engagement of a pin 58 on the sleeve with inclined teeth 54, on the fixed casing, whereby one of the slots 48 is presented to the previously locked out clutch lever 30, whilst the previously effected lever 32, is locked out by one of the abutments 50 therebetween, the sleeve 46 being locked in the new position by casing teeth 44. In Fig. 5, not shown, the lock-out sleeve 46 is replaced by a stop arm (66) pivoted to the hydraulic cylinder and swung laterally into abutting relation with either clutch lever by a pulse produced by overtravel of the actuator.

Title: Improvements in spools or carriers for photographic paper, celluloid or the like strips
IPC: G03B17/30
Filed: 1929-12-10
Abstract: 345,290. Photographic roll spoolholders. SMITH, W., 25, Charles Street, Haymarket, and BRAMWELL, J. E., 9, Harrow Road, Paddington, both in London. Dec. 10, 1929, No. 37813. [Class 98 (i).] A cylindrical casing for use on portable cameras &c., to receive sensitized paper, celluloid, &c. strip, of the kind which encloses a bobbin and has a removable end and a longitudinal feed opening one edge of which is turned up out of the normal cylindrical contour of the casing to form a flap, is characterized in that this flap is adapted to be bent back into the cylindrical contour of the casing to close the feed opening. The complete spool assembly comprises a supply spool 3 on which the strip 1 is wound, a take-up spool 5 to which the free end of the strip is attached, and a cylindrical casing 6 which encloses the take-up spool and has a longitudinal entrance slot for the passage of the strip. The casing 6 may be formed by rolling a sheet having rabbeted edges 8, 9, the edge 8 being formed on an upturned lip 7 which acts as a stop to prevent rotation of the casing when in use in the camera ; and its ends may be closed by caps 14 which have apertures 15 giving access to the winding-key slot &c. of the enclosed spool, and have notches 12 normally bounding the entrance slot in the casing. When all the strip has been wound into the casing, the caps are rotated to cause the edges of the notches 12 to depress the lip 7 until the rabbeted edges 8, 9 snap together and close the casing.

Title: Improvements in electrically driven portable machines for sewing up bags and sacks
IPC: D05B13/00
Filed: 1957-12-10
Abstract: 837,652. Sewing machines. UNION SPECIAL MASCHINENFABRIK G.m.b.H. Dec. 10, 1957 [Dec. 19, 1956] No. 38304/57. Addition to 816,812. Class 112  The electrically-driven portable sewing machine of the parent Specification is modified by mounting the feeler, which by rising and falling under the influence of workpieces fed to the stitch-forming devices serves to open and close a switch in the circuit of the driving motor, on a member guided or carried mainly within the machine casing. A driving motor 2 is secured by a flange 9 to the sewing machine casing 1 and is provided with a handle 3 carrying a switch 5 normally held in the closed position by a spring catch 6. A switch 7, secured to flange 9 by a bracket 8, is connected by a cable 10 to switch 5. A rod 16, slidable in bushes 17, 18 within casing 1, carries at one end a block 19 projecting from the casing and at the other end feeler 11 disposed mainly within the casing. Block 19 engages a spring-biased actuating pin 22 for switch 7. Feeler 11 lies in a slot in the needle plate 24 adjacent the feed dog 15 and projects into a slot in the presser foot 25 adjacent the feeding foot 14. Passage of workpieces between the feeding members 14, 15 depresses feeder 11 to shift rod 16 axially for closing switch 7 against the spring bias of pin 22 to start motor 2. An arm 11A connects feeder 11 to a member 11B extending outwardly of casing 1, whereby motor 2 may be started by depressing member 11B manually if a workpiece is too soft to depress feeder 11. Switch 7 is protected by a cover plate 26 attached to easing 1 by screws 27, 28. Specification 784,110 is referred to.

Title: Motor vehicle occupant restraint system
IPC: B60R21/16
Filed: 1972-08-17
Abstract: 1346258 Crash restraint devices; bumpers GENERAL MOTORS CORP 17 Aug 1972 [27 Aug 1971] 38402/72 Headings B7B and B7J In a vehicle having an inflatable crash restraint bag and an inflating gas source, means are provided for inflating the bag at different rates dependent on the intensity of crash impact. The gas source comprises a pressure vessel sealable in two ways. In a first arrangement the vessel has two adjacent outlets of different area each closed by a detonator rupturable seal. Crash impact above a predetermined minimum causes the smaller outlet to be opened, and above a predetermined maximum causes both outlets to be opened. Alternatively the vessel is closed by a plug with a through bore, a second plug located in the bore and having a further through bore, and detonator rupturable seals closing the further bore and the gap between the plugs. On low impact the further bore is opened and on high impact the seal between the plugs is broken to open the first bore. The crash impact is sensed by inertia switches 44, 44<SP>1</SP> and a bumper assembly. The bumper 18 is mounted on a cylinder 24 slidable within a fixed cylinder 22; cylinder 24 being closed by an apertured piston defining with cylinder 22 a first hydraulic chamber and contains a gas loaded piston defining with the apertured piston a second hydraulic chamber. A metering rod fixed to the closed end of cylinder 22 passes through the apertured piston. On impact cylinder 24 moves rearwardly and fluid flows from the first to the second chamber, the flow being progressively reduced by the metering rod, and the pressure in the first chamber is increased. Pressure change is sensed by a piezoelectric transducer 34 set to be actuated at a particular pressure. An inertia switch 44, also set for actuation at a predetermined minimum, is connected in circuit with the transducer so that detonators 42, controlling the lower gas rate release, are fired only when both 34 and 44 are actuated. Switch 44 includes a ball 46 seated on a contact plate 48 by a permanent magnet 50, the ball moving radially on collision to contact a second plate 52 and complete the circuit. A second switch 44<SP>1</SP>, set to be actuated at higher impact, controls firing of detonators 60 for releasing the maximum gas flow. At higher impact the detonators 60 are fired only after both switches 44, 44<SP>1</SP> have been actuated, the transducer although actuated is not instrumental in gas release.
