Title: Friction shock absorber
IPC: F16F7/06
Filed: 1927-11-21
Abstract: 288,108. Masquelier, R. July 19, 1927, [Convention date]. Vibration - dampers.- Single - acting vehicle shock - absorbers include two cam or wedge shaped elements engaging the interior of an expansible brake drum in such a way that the first part of the effective stroke expands the cams radially while further movement rotates them. A casing 1 secured by bolts 3 to the frame or axle encloses a split brake band 18 having end lugs 19, 20 which are drawn together by a bolt 22 and an adjustable helical spring 23. Within the brake band 18 is disposed a friction band 17 which is expanded and rotated by cam or wedge shaped elements 16 engaged by eccentric surfaces 15 mounted on a spindle 14 carrying an arm connected to the axle or frame. Projectors 27 on the eccentric 15 engage somewhat wider recesses in the cams 16. When the eccentrics are rotated in a direction opposite to the arrow 26, the cams 16 move inwards and turn freely, but when the eccentrics move in the same direction as the arrrow, the first part of the movement expands the cams radially, until the slack of the recesses 28 is taken up, when the radial expansion ceases and the cams rotate.

Title: Improvements in or relating to apparatus for forming separators for the cages of ball- or roller-bearings
IPC: B21K1/04
Filed: 1920-05-07
Abstract: 164,667. Miller, C. H., and Skefko Ball Bearing Co., Ltd. May 7, 1920. Bearings. - A machine, for forming separators for the cages of ball or roller bearings as described in Specification 157,676, [Class 12 (i), Bearings &c.]. comprises two punches 10, 11, Fig. 4, between which short lengths of tube 24 are fed to be pressed laterally to the shape shown at 28, the punches having heads 12, 13 shaped according to the rolling members between which the separators are to be mounted, and being reciprocated in arcuate guides 14, 15 having an effective radius equal to that of the pitch circle of the assembled rolling members. The punches at the completion of their pressing movements occupy the same relative positions as the rolling members when assembled in the cage. The punches are reciprocated by connecting-rods 22, 23 and cranks 20, 21 on gear-wheels 18, 19 meshing with a pinion 17 on a vertical shaft 16 driven through gearing 33, 34, Fig. 2, from a shaft 32. The rod 23 is longer than the rod 22 so that the pressed tube 28 is conveyed to a delivery shoot 29. The tubes 24 are fed down an inclined guide 25 on to a plate 26, Fig. 1, where the tube is held in correct position by a spring-controlled abutment 27 automatically operated from a cam-disc 35 on the shaft 16 so as to rise to permit entry of tube, then to descend to hold it until gripped by the punches and then to rise to release tube for delivery. The plunger 11 has a nose 30 to hold the tubes in the guide 25 clear of the tube which is being pressed. The pressing operation may occur while the tube is stationary or while it is being moved towards the shoot 29. One or both heads 12, 13 may be mounted resiliently to the body of the punch. Two wires 42, 43 are fed into the tube 24 through holes 41 in the plate 26 and spring-controlled guides 52 by friction-wheels 44, 45 driven by a gear-wheel 46 from shaft 32 and coupled thereto by a clutch 47 operated by a lever 48 from a cam 49 on shaft 16, so as to cause an intermittent feed. The wires are severed to the desired length to act as rivets in the completed cage by a knife 50, Fig. 1, secured to the plunger 10 and co-operating with the underside of the plate 26. The severed wires are secured in the tube by the pressing, the holes 41 being shaped to allow for the displacement resulting from the pressing. As the tubes move towards the shoot, the wires are moved into correct position by an inclined plate 51, Fig. 1, the wires moving in grooves in the plate 26 during this movement.
Patent GB-1460906-A (GB)
Title: Automatic cueing device
IPC: G11B27/22
Filed: 1973-07-02
Abstract: 1460906 Cueing system P J MORGAN-SMITH 2 Oct 1974 [2 July 1973] 31380/73 Heading G5R In a cueing device for an audio system using a gramophone record or tape recording medium, the record or recording medium is stopped when the commencement of an audio passage is detected. Raising and subsequently lowering a pick up arm into contact with the start groove of a record acts via switch 16 to mute 12 the audio output path and also acts after a delay to prepare latch 15 so that when an audio output from pick up cartridge 10 is detected 14 a solenoid is operated to stop rotation of the record. This can be done by supporting the record on a mat 3 having a diameter greater than turntable 2 and then clamping the mat by means of a plunger or clutch 5 operated by the solenoid. On operating a play switch 20 the audio output path is reconnected and the solenoid is released so that the record rotates to play the passage from its commencement. In a second arrangement the pick up can be lowered into the groove in a preceding recorded portion of the record and the device then acts to stop the record at the commencement of the next recorded portion. In a third arrangement not using a clutch a reversible turntable motor and turntable rotation sensor are provided and operate with an up/down counter and control circuitry to compensate for overshoot of the start of the audio passage when the record is stopped. By presetting a particular count in the counter the cue point can be positioned in advance of the start to allow time for the turntable to reach play back speed before the passage commences. A similar system is described for use with a tape recording medium.

Title: Improvements relating to the operation of signal or token releasing instruments for block section working of railway lines
IPC: B61L23/24
Filed: 1921-11-23
Abstract: 189,983. Tyer & Co., Ltd., and Leake, F. W. Nov. 23, 1921. Staff, tablet, and ticket systems; interlocking and controlling and locking signals; hand-levers. -The lock on a tablet instrument or a signal is released electrically only after the receipt of a plurality of impulses transmitted in the same direction and during the maintenance of the final impulse. The armature 2, of an electromagnet 1 is connected to a rack-rod 3 which, through a ratchet gear, drives a clock escapement so that the rod can rise freely when the armature is attracted, but falls at a speed determined by the escapement. An extension 13 of the armature carries a leaf spring 14 supported on both sides by other springs 15. A pin projects laterally from the upper end of the leaf spring, and when the armature is attracted, presses upon, and the spring is deflected by, the first of a series of inclined blades 19. The spring 14 rises until the pin passes the blade 19 and is stopped at the root of one of a series of shorter blades 20. During the slow falling of the rack-rod 3, the spring 14 is moved into a central position by one of the springs 15 and therefore passes on to the upper surface of the blade 19. Subsequent actuations of the armature bring the pin on the spring 14 to the top of the series of blades, and at that time, a contact on the rack-bar 3 bridges contact 22 in the lock-removing circuit and the lock remains off until the armature 2 is released and the rackbar 3 falls sufficiently to open the contacts 22. If the sequence of impulses is not completed, the pin on the leaf spring 14 runs off the outer end of the blade 19, supporting it, and the device returns to its initial condition. In place of the escapement control, the rod 3 may extend a bellows with a free entrance for air and a restricted egress.

Title: Gas turbine rotor assembly
Inventor: HARLOW DORIS JEAN
IPC: F01D5/22
Filed: 1964-08-05
Abstract: 1,014,577. Gas turbine engines. GENERAL ELECTRIC CO. Aug. 5, 1964, No. 31902/64. Headings F1G and FIT. A turbo-machine rotor assembly includes a rotor wheel supporting a plurality of blades, each comprising shank and vane portions between which is a platform; adjacent platforms abut each other, and baffles are secured to the wheel on the up- and downstream sides of the shanks to prevent axial gas flow between the shanks; the baffle plates on one side of the shanks are spaced from the rotor wheel to provide a passage for coolant fluid flow into chambers formed by the shanks and baffle plates, the coolant passing from these chambers to internal cooling passages in the blades; the baffle plates on opposite sides of the rotor wheel are interconnected by damper pins, which seal the joints between adjacent platforms, and which also damp vibrations of the blades. The invention relates particular to aircraft gas turbines. As seen in Fig. 1, the blades are mounted in pairs, each pair of roots 12, 14 sharing a common dovetail 32. The baffles 25, 26 are held by bolts 30 (Fig. 2) at their lower ends, and are spaced from the rotor wheel face by bosses to allow coolant to pass from the space 50 to the blades. The damper pins 41 have a control portion of semi-circular cross section, and end faces of circular form, carrying an elongate diametral shoulder (43 in Fig. 5, not shown); these shoulders engage in elongate slots 40 in the baffle plate peripheries. When nuts are fully tightened on threads 44, the baffle plates are constrained axially, but the damper pins are free to move radially under centrifugal loading. Thus when the rotor is running, the curved surfaces of the damper pins are pressed into tight sealing engagement with the joints between adjacent blades belonging to adjacent pairs. In addition, since the damper pins are loose, and in rubbing contact with the blade at a point well clear of its rigid end, they act as dampers of blade vibration. Since there are no small coolant passages through the rotor wheel, the expense of replacing clogged rotor wheels is avoided.
