Title: Improvements in engine starter drive
IPC: F02N15/02
Filed: 1949-01-18
Abstract: 661,195. Turning-gear. BENDIX AVIATION CORPORATION. Jan. 18, 1949 [Jan. 19, 1948], No. 1434/49. Class 7(v) In an engine starter drive comprising a power shaft 2, a driving clutch member 7 splined thereon and having inclined teeth, a screwshaft 4 slidably journalled on the power shaft, a driven clutch member 5 connected to the screwshaft 4 and having correspondingly inclined teeth for co-operating with the teeth of the driving clutch member 7. a pinion 22 threaded in the screwshaft for longitudinal movement into and out of mesh with a gear 23 of an engine to be started, and an abutment member 11 for defining the normal position of the screwshaft 4 and for arresting the gear engaging movement of the pinion 22, the abutment member 11 being carried by the power shaft 2, there is provided spring means, such as helical springs 15, for pressing the driving clutch member into operative engagement with the driven clutch member.. In operation, rotation of the power shaft 2 is transmitted through the ratchet clutch 5, 7, the driven member of which is formed as part of the screwshaft 4, the clutch being at first lightly loaded by the springs 15. The. pinion 22 traverses the shaft 4 into mesh with the engine, gear 23. Should tooth abutment occur the spring 15 will yield and cause the clutch to slip and effect correct indexing. After the pinion is in mesh, the shaft 4 slides leftwardly over shaft 2 until the member 7 engages a series of heavy springs 15a which present a. greater resistance to further movement of shaft 4 and so increase the clutch loading. Further axial movement of the shaft 4 is prevented when it abuts a self-lubricating thrust bearing 29 on the power shaft in which position the clutch loading is a maximum. Whenever normal cranking torque is exceeded either during initial acceleration of the engine or as the result of a backfire, the clutch members will ratchet over each other until the overload ceases. The shaft 4 is retained on the shaft 2 by the abutment 11 between which and the pinion, is located an antidrift spring 25, the front of the pinion being recessed and fitted with a thimble 26, which, in the meshed position, bears against the abutment. The extreme leftward position of the pinion is defined by a backstop 24 attached to the screw shaft 4.

Patent GB-389227-A (GB)
Title: Improved means for controlling the running movement of sound record or combined sound and picture record films or the like
IPC: G11B15/34
Filed: 1932-01-18
Abstract: 389,227. Film-driving mechanism. AGA-BALTIC RADIO AKTIEBOLAG, Norra Bantorget, Stockholm. Jan. 18, 1932, No. 1515. Convention date, Jan. 17, 1931. [Class 40 (ii).] Film-driving mechanism, particularly for use with sound-recording or reproducing apparatus, comprises constantly driven feed and take-up sprockets intermediate of which are freely-. rotatable guiding members around which the film is wrapped, film loops being arranged on either side of the guiding members. The film 1 is fed in a loop 25 from a sprocket 3, Fig. 1, to freely-rotatable members 4, 5, Fig. 2, and from thence is led in a second loop 29 to a take-up sprocket 9. The film-driven members 4, 5, which may be covered with rubber, are carried on shafts 18, 19, respectively, and are fitted with flanges 13, 14 serving as supports for the edges of the film which is pressed against the members 4, 5 by conical guide rollers 7, 8. To facilitate winding of the film 1 on the wheels 4, 5 the wheel 5 is provided with a conical-shaped extension 22. The shafts 18, 19 are carried by bearings 23, 24, respectively, and to the shaft 18 is secured a hollow flywheel 20 surrounding a second flywheel 21 freely mounted on the shaft 18. Irregularities in the speed of the film are smoothed out by the action of the flywheels 20, 21 and the effect of the flexibility of the loops 25, 29, so that the film is moved uniformly past the sound-recording or reproducing point 2. The Specification as open to inspection under Sect. 91 states also that part of the. power required to drive the wheels 4, 5 may be transmitted -from the driving motor of the sprockets 3, 9 through a friction-coupling. This subjectmatter does not appear in the Specification as accepted.
Patent GB-385757-A (GB)
Title: Improved high tension electric switch particularly adapted for x-ray devices
IPC: H01H33/24
Filed: 1932-01-18
Abstract: 385,757. High potential switches. MLLER AKT.-GES., C. H. F., 24, Rontgenstrasse, Hamburg. Germany. Jan. 18, 1932, No. 1518. Convention date, Jan. 21, 1931. [Class 38 (v).] A H.T. switch for controlling X-ray apparatus comprises two spaced metal globes 6, 7 of relatively large curvature so that a discharge does not readily pass between them, the upper globe 7 having an aperture 15 through which a switching rod 14 is adapted to project. Normally the rod 14, which is attached to an armatute, is held within the globe 7 by an electromagnet 9. On opening the switch 13 in the circuit of the electromagnet the rod 14 falls into a recess in the globe 6 thus bridging the two globes and allowing a potential accumulated on the condenser 3 to energize the X-ray tube 1. The rod 15 may, alternatively, be arranged so that its tip does not actually touch the lower globe but approaches sufficiently closely to permit a discharge in the gap between the tip of the switching rod and the globe. On reclosing the switch 13 the rod 14 is again raised and the circuit of the X-ray tube broken. After switching off by retraction of the rod the globes may be subsequently drawn apart to isolate the tube or to break an arc which may persist between them. The globes 6, 7 may be replaced by paraboloids or by flat plates the edges of which are bent or thickened to form rounded portions. A suitable inductance 4 is included in the energizing circuit.
Patent GB-1165392-A (GB)
Title: Improvements in Rotary Funnels Employed for Winding Fibre Slivers in Crossed Reels
IPC: B65H54/02
Filed: 1967-01-11
Abstract: 1,165,392. Winding slivers; twist tubes. N. SCHLUMBERGER & CIE. 11 Jan., 1967 [21 Jan., 1966], No. 1528/67. Headings DID and D1N. A false twist tube funnel 1 for traversing a sliver onto a cross-wound reel has a reciprocating rotational movement about its axis, a pivotal movement about an axis 3 at right angles to the axis of the winding-on roll 9 and a movement parallel to the axis of roll 9, the latter movements being synchronised so that the delivery end of the funnel moves along a line e-e 1  parallel to the axis of the roll 9. Twist tube 1 is rotatably mounted in a support (2), Figs. 2, 4 not shown, pivoted about an axis 3 on an arm 4 pivotally mounted on the machine frame at 5. Arm 4 is rocked to and fro by a crank mechanism (7, 36, 27) Fig. 3 not shown, and support (2) is rigidly attached to a rod 10 pivoted at 13 to a rod 11 pivotally mounted on the m/c frame at 12; thus the central point of the twist tube follows a path d while the tube itself is rocked by arm 10 to cause the delivery end to follow line e-e 1 . An oscillating rotary drive is transmitted to false twist tube 1 from a crank mechanism (16, 17, 31), Fig. 3 not shown via a toothed sector (15) rockable about shaft 5, gears (18, 21), chain (22), gear (23) on shaft 3 and finally via a bevel gear arrangement (24, 25) Fig. 2 not shown, to the twist tube. The crank mechanisms for arm 4 and the twist tube rotation are both adjustable for different length of package and different degree of twist; it is preferably arranged that the twist tube does not reverse its direction of rotation as the direction of traverse of the twist tube reverses. The twist tube is mounted in an easily releasable mounting to be replaceable for different materials. The simple harmonic motion of the rockerarm is accelerated in the region of its reversal point and slowed in the region of its central position to make the traversing speed of the funnel more nearly uniform; this is done by driving the crank mechanism through elliptical meshing gears or eccentrically mounted circular gears.
Patent GB-913796-A (GB)
Title: Improved process and apparatus for the drying and burning of mixed pallets
IPC: C05B19/00
Filed: 1961-01-13
Abstract: <PICT:0913796/III/1> A continuous drying and burning apparatus for preformed phosphate pellets comprises two travelling grates in series, the first passing the pellets through one or more drying chambers, one or more burning chambers and a hardening chamber, which chambers have gas suction outlets below the grate, and whence the pellets are passed through a heat compensation chamber to the second, lower grate which passes through a cooling chamber having a gas pressure inlet under the grate.  The pellets are fed on to the first grate 10 by a shoot 43 under a stripper 45, which grades the depths of pellets across the grate.  The grate passes through drying chambers 1-3 heated by gases from the burning chamber via blower 27, and from the hardening and cooling chambers via blower 33, by lines 35-37, the gases being drawn through the grate by a fan 41 and finally exhausted through a line 46.  The grate then passes through the burning chambers 4, 5 with gas burners 16, where the top four-fifths of the pellets are burnt, and the hot gases are drawn off from the lower chambers 13, 14 by the blower 27 through lines 23, 24. The grate finally passes into a hardening chamber 6, where the lowest layer of pellets, which until now has served as a protective layer for the grate, is burnt by the heat from the upper layer, and the gases are drawn off below the grate by the blower 27 through lines 25.  The pellets are now thrown off grate 10 by a shoot 50 into the heat-compensation chamber 7, hot gases being drawn off by the blower 33 through line 32, and any extra heat required being provided above the grate by an opening 17. The second grate 11 withdraws the pellets from chamber 7, passing them through the cooling chamber 8 and out via a shoot 44.  Below the grate is a blower 30 feeding cool air under pressure to outlets 28 through lines 29.  Some hot gases are drawn off by the blower 33 through line 31, and exhaust gases pass up the chimney 9.

Patent GB-215694-A (GB)
Title: Improvements relating to electric power control systems
IPC: H02P29/00
Filed: 1923-02-05
Abstract: 215,694. Hild, F. W. Feb. 5, 1923. Hunting switches.-In a motor control system, the load on a motor is controlled by devices operated by a contact on the pointer of a wattmeter engaging contacts positioned at the limits of a predetermined range of power. The wattmeter has a current coil 18 connected to a transformer 62 in the circuit of an induction motor 41, and a voltage coil 16 connected to a voltage transformer 61 connected across one of the phases of the motor 41. A pointer 23 controlled by the usual rotatable disc 20 and spring 22 moves over a fixed scale 5, which is graduated to indicate the effective weight of the drill, when the devices are used in earth-boring apparatus as described in Specification 215,427, this being proportional to the load on the motor 41. A maximum demand segment 6 mounted on a tubular shaft 7 carries a pointer 7 adapted to indicate the maximum power used. In order that the work of moving the segment 6 may not be directly imposed upon the pointer 23 with consequent inaccuracy of indication, the pointer carries a contact 24 adapted to engage a contact 25 carried by the segment whenever the pointer indicates a load at least equal to the previous maximum. The engagement of these contacts closes a circuit derived from the transformer 61 energizing a coil 31 to withdraw a spring biased brake 34 from a clockwork mechanism 14 which thereupon drives a pinion to 37 to turn the segment 6 towards the new maximum until the contacts again separate. A pressure limit dial 9 is carried by a chart 10 passing through the shaft 7 and engaged by a friction band 7a so as normally to move with the segment 6. The maximum power taken by the motor corresponds to the weight of the freely suspended drill when used in earth 'boring apparatus and when the drill touches the bottom of the well is diminished in proportion to the pressure of the drill bit on the bottom, thus a scale of the dial 9 indicates the pressure. This dial is set relatively to the segment 6 by means of a knob 11 so that when the pressure, reaches a predetermined value the contact on the pointer, which has moved back from its maximum, engages a contact 26 on the dial to establish a circuit for operating a control system, causing the motor 41 to take a greater load, and thus reducing the pressure on the drill bit. After a cycle of operations the segment 6 is reset to its zero position by a knob 8 on the shaft 7 in which position a contact 27 thereon engages a stationary contact 28 to establish a circuit for returning the control system to its normal position.
