Title: Unloading machine
Inventor: YAMASHITA UMEO
IPC: B65G59/02
Filed: 1970-11-19
Abstract: 1276070 Unloading pallets; load lifting apparatus YAMASHITA TEKKO KK 19 Nov 1970 55084/70 Headings B8A B8C and B8H Apparatus for unloading bottle crates from pallets comprises rollers 26 reciprocable towards the crates, belts 46 movable with the rollers to scoop the crates on to the rollers, belts 45 above the belts 46 to prevent the crates tumbling and a stop 89 preventing the crates from moving away from the belts. A conveyer 6 feeds pallets to lines 12 of an elevator 11 which is raised by chains 16 to present succeeding layers of crates to the belts 46. The rollers 26 are reciprocated by endless chains 28 the links of which are secured to the ends of the rollers. Each roller is rotatably connected to adjacent rollers by separate chains, one roller being directly driven. At the downstream end of the line of rollers 26 there are a roller 97 driven at a faster speed than rollers 26 and a stop bar 93 mounted on plates 94 which are downwardly pivoted when theadjacent end of a delivery conveyer 101 is free of crates. Plate 109 on the conveyer 101 orientates the crates in a lengthwise direction on the conveyer. Motors M1-M7 driving the various parts are automatically controlled by photoelectric devices and limit switches.

Abstract: 1397590 Back-pedalling brakes FICHTEL & SACHS AG 30 Nov 1972 [2 Dec 1971] 55447/72 Heading B7E [Also in Division F2] A three-speed planetary hub gear on a pedal cycle, having a fixed sun 13, provides overdrive when, as shown, a toothed clutch sleeve 5, permanently splined in a sprocket-carrying input member 2, clutches teeth 42 in a planetcarrier 6 to overdrive a ring gear 4, the internal teeth 27 (Fig. 1a) of which clutch teeth 25 of an axial extension 22 of a freely mounted first driven member 16, pawls 19 of which then drive the hub shell 3; direct drive when the clutch sleeve 5 is moved axially one step rightwards to disengage the carrier teeth 42 and engage teeth 34 of the ring gear 4 whilst the internal teeth 27 (Fig. la) of the latter still remain clutched at 25 to the first driven member 16 so that the pawls 19 of the latter now drive the hub shell at input speed; and reduced drive when the clutch sleeve 5 is moved an additional step to the extreme right, so that, whilst still remaining clutched to the ring gear 4 at 34, it takes axially along with it, through a thrust washer 35, the ring gear 4, the teeth 27, (Fig. 1a) of which disengage the teeth 25 of the first driven member 16, whereupon previously overrun pawls 20 of a second driven member 16, associated with the planet carrier 6, drive hub shell 3. In Fig. 1, the second driven member 17 is screw-threaded on the carrier hub 6 and has a cone surface 45 expanding a diametricallysplit back-pedal brake ring 46.  To avoid back-turn lock-up, i.e. a condition which obtains when, if the cycle is wheeled backwards whilst in second or third gear with the back pedal brake still in engagement, the first pawls 19 engage before the second, 20, resulting in the back pedal brake being applied more strongly, causing possible damage and non-release on subsequent forward pedalling, the clutch teeth 25 of the first driven member 16 engage the teeth 27 of the ring gear 4 with a degree of lost motion (Fig. 4, not shown), which is greater than the tooth pitch of the second pawls 20, and so ensures that the second pawls 20 engage before the first 19 and causes the second driven member 17 to be screwed rightwards to release the brake.

Abstract: 1449513 Brake boosters AISIN SEIKI KK 29 Nov 1973 [29 Nov 1972] 55460/73 Heading F2F A vacuum suspended booster or servomechanism for a hydraulic brakes system comprises means 55 for combining and transmitting forces from a mechanical input member 23 and a power member, said means 55 being out of contact with the mechanical input member 23 when at rest but being displaceable into contact with the said member when the brakes are operated. The force combining means 55 comprise radial levers 56 having their radially outermost end portions engaged with a resilient means formed by a spring 61 and plate 58 biasing the means 55 to a rest position. Initial movement of the input member 23 operates a valve 43, 45 to isolate the chambers 26, 27 of the booster from each other and open a valve 43, 44 to place chamber 27 in communication with atmosphere so that the diaphragm 20 is moved and the master cylinder operated, the levers 56 moving to engage a shoulder 67 so that direct pedal force is then added to the power force. As hydraulic pressure increases in the master cylinder it reacts against the output rod 22 so part of the reaction is transmitted via the levers 56 to the pedal 24 to provide "feel".

Abstract: 1,215,802. Grabheads for use with nuclear reactors. ENGLISH ELECTRIC CO. Ltd. 27 Dec., 1967 [30 Dec., 1966], No. 58467/66. Heading B8H. To raise a nuclear fuel element a grabhead, Fig. 1, is lowered on to a lifting button 28, Fig. 2 (not shown), with the jaws 25 open as shown. In this state a solenoid 18 is energized and a plunger 24 is in a first position. The whole jaw assembly 11 is supported by jaw-shields 17 through the jaws 25. When the jaw assembly comes to rest on the lifting button the solenoid is de-energized and a spring 22 forces an actuating sleeve 23 and the plunger 24 downwards to a second "jaws closed" position, Fig. 2 (not shown). Simultaneously the jaws 25 are cammed closed by surfaces 25A, 23C. The grabhead is now raised by the cable 15 until the jaw-shields come into contact with the jaws. The jaw assembly 11 is now supported by the body assembly 10 through the jaws and shields, the plunger 24 being in a third or "supported" position, Fig. 3 (not shown). Further raising of the cable brings the jaws into lifting engagement with the lifting button. The position of the plunger 24 is monitored by an A.C. current passed through the D.C. solenoid leads. Fig. 4 shows a second embodiment in which the jaws are held open by a probe 40 instead of by the solenoid 18. When the jaws are opened by the solenoid a spring 43 forces the probe 40 downwards to the position shown in Fig. 4. As the grabhead is lowered on to the lifting button the probe 40 is pushed up relative to the member 21 and the spring 22 pushes the sleeve down to close the jaws as previously described. The probe 40 is now held in the raised position until the jaws are opened again by the solenoid.
