Title: Mechanical rammer for blocks of agglomerates and other blocks
IPC: B28B1/04
Filed: 1930-01-31
Abstract: 354,286. Tamping machines for moulding concrete &c. blocks. SYNDICAT DES BREVETS BLOC ATHERMANE KNAPEN, 17, Rue Le Peletier, Paris. Jan. 31, 1930, No. 3382. Convention date, Jan. 31, 1929. Void [Published under Sect. 91 of the Acts]. [Class 87 (ii).] Blocks of agglomerates are moulded by progressively ramming successive layers of the agglomerate in a mould by means of a low-power ramming machine. The mould 56 is moved laterally in guides on the table 3 until it registers with the multiple rammers 33. Depression of the pedal 66, Figs. 1 and 4, then raises the cores 60 into the mould which is then filled from a hopper 4. The operator next raises the handle 48 from its neutral mid-position after starting the motor 5. This releases the weighted band-brake 52, Figs. 1 and 7, through the medium of the rod 55 and allows the rammer head 27 to fall, revolving the shaft 42 through the medium of the belt 44 during the process. The downwardly-moving rammer head swings the weighted lever 22, Figs. 1 and 2, about the pivot 24 and so raises the rod 19 to apply tension to the belt 9 through the medium of the pulleys 13. The shaft 8 thus is driven from the motor shaft 6 to cause the cams 17 to coact with projections on the rammers to raise them independently and in timed relation through springs 38 and against the action of other springs 32 before releasing them to fall on to the material in the mould. At the completion of the operation the head 27 is again raised by depressing the lever 48, Fig. 7, below mid-position, thus tensioning the belt 40 and transmitting a drive from shaft 6 to shaft 42 to wind up the belt 44. This cuts off the drive to the tampers and restores the lever 22, Fig. 2. After withdrawal of the cores by releasing the pedal 66, the mould can be removed.

The table A carries sweeps 39 to force the graded material into separate delivery troughs 38. Periodically stiff brushes carried by A, can be rocked over by hand, to sweep the troughs 35, 35<1>. The currents of air, can be regulated by movement of a shield 23<1> having holes to align, or otherwise, with the holes 23. A further regulation comprises a plate 107 which can be turned by rotating a knob 112 to reduce, or increase; the size of the hole 106 leading to the air exhaust 66. A disc 72, for scattering the material admitted through a duct 22a, is fixed to a high speed shaft 64 driven by an external pulley 88, and internal pulleys 95, 96 connected by rope drives. The table A is driven from the same source through pulleys 92, 91 and a slow-speed shaft 34. The belt drives are tensioned by a jockey wheel 81 acted on by a spring 85. Adjustable deflectors 45 sweep material into grooves 28 on either side. The deflection may be angularly adjusted by screw knobs 57 causing movements of slides 50. The position of each slide is shown by a pointer protruding through a slot in a graduated scale S. The air currents pass either downwards or upwards inside a partition 69, through holes 62, and down the inside of a tube 27. Baffles 76 prevent the air from being rotated. The table A and the disc 72 are rotated in the same direction. A cone 67 acts as a material spreader. Windows are provided in the casing 21. Specification 549,019 is referred to.

Title: Improvements in drive mechanism for transverse means in winding machines
IPC: B65H54/28
Filed: 1958-02-03
Abstract: 839,150. Winding; traverse mechanisms. SYNCRO MACHINE CO. Feb. 3, 1958 [Sept. 6, 1957], No 3517/58. Class 120(2)  Driving mechanism for traverse means in winding machines comprises a rotatably mounted lead screw, a reciprooable guide having a nut engaging the lead screw, driving means including a pair of oppositely acting clutches each including a driving gear alternatively connectible to the lead screw and means driven at a predetermined speed for applying a series of successive driving impulses to the clutches to rotate them alternatively in opposite directions for each successive series, and selective means including an operator actuated by said nut, and a gear for alternatively co-operating with the driving gears for selectively controlling the driving means to cause said alternative rotations, the means driven at a predetermined speed for applying said driving pulses to the clutches including an adjustable stroke, crank operated rack bar, and means for preventing backlash movement of said lead screw during the period between driving pulses. One embodiment of the invention is shown. In operation, assuming that the traversing nut 22 is moving to the left and is about to reach the extreme left-hand position, as the nut moves to the left it comes into contact with flanged sleeve 82 and begins to move it towards the flanged sleeve 80 fixed to the shaft 62 thereby compressing the spring 84. When these sleeves engage the shaft 62 is moved to the left until the roller 100 is on the cylindrical portion of the collar 92 at the right hand end of the shaft 62. The compressed spring 84 will then kick the shaft 62 to its extreme left hand position bringing the gear 60 out of engagement with the gear 72 and into engagement with the gear 70. This action through unidirectional clutches reverses the drive to the lead screw 20 thus reversing the direction of movement of the nut 22. A similar action .occurs when the nut 22 reaches the other end of its traverse. The drive to the gear 60 is from a crank mechanism 54 through a rack 46 and gear 36 which mechanism by virtue of the unidirectional clutch drives from gears 70 and 72, imparts rotational pulses to the lead screw 20, the reverse movement of the rack 46 not being transmitted by the unidirectional clutches. The length of the stroke of the rack and therefore of the rotational pulses can be adjusted by the screw 52 and by the speed of rotation of the driving sprocket 58. The length of the traverse movement of the nut 22 is adjusted by positioning the sleeves 80 and 86 on the shaft 62 and locking them by set screws.

Title: Improvements in and relating to delay action devices employing thermionic valves
IPC: H03K17/288
Filed: 1921-01-29
Abstract: 178,957. Lea, N., and Radio Communication Co., Ltd. Jan. 29, 1921. Thermionic relays. - Relates to delaying or retarding arrangements, particularly for the reception of signals, and consists in utilizing as the delay period the time taken in charging or discharging a condenser through a resistance. The condenser is preferably arranged in the grid circuit of a thermionic valve, and the prime movement connects the condenser to a resistance, the final switch being operated by a coil in the plate circuit of the valve. As shown, the condenser C is charged by the battery B, whenever the arm T rests on the spacing-contact S, and the grid G of the valve V is thus kept at a negative potential and no current passes in the plate circuit. An incoming signal moves the arm T to the marking-contact M and connects the grid G and the upper plate of 'the condenser C through a high resistance R1 to a positive point on a battery B2. After a limited time, the potential of the grid G reaches a critical value such that sufficient current is allowed to pass through the valve to operate the relay 0 and to close the output circuit of the contact W. The critical grid potential should be near the middle of the rising grid-potential plate-current characteristic, and this critical grid potential should be attained before the charge on the grid G and condenser C have approached too nearly to their ultimate values. When the arm T moves back to the contact S, the grid is immediately charged negatively and cuts off the current through the relay O. A low resistance R2 prevents sparking at the contact S.
