Title: Improvements in or relating to pile driving methods and apparatus
IPC: E02D7/20
Filed: 1938-11-18
Abstract: 518,156. Pile driving. OKA,.K. Nov. 18, 1938, No. 33639. [Class 68 (ii)] The pile is first pushed down into the ground by a winch operating through the intermediary of a power-operated hydraulic press and is driven to its final position by the hydraulic press, the connection between the winch and the press providing the re-action to the thrust of the press. The hydraulic press 3 bears upon the head of the pile 5 and is movable vertically in guides 2 forming part of the tower. Ropes running under pulley 40, 40' connect the press to a plunger frame 12 also guided vertically and raised by multiple pulley mechanism 20, whereby the pile is pushed into the ground. The final movement of the pile is effected by operation of the hydraulic press, the fixed part of wheel is held against upward movement by the plunger frame and its connections. To prevent movement of the tower, ballast 20' is connected thereto by a derrick 1'6. The various ropes are operated by connections to the winch.

Filed: 1957-11-01
Abstract: 870,336. Wadding. FORSCHUNGSINSTITUT FUR TEXTILTECHNOLOGIE Nov. 1, 1957, No. 34188/57. Class 42(2) Transverse reinforcing threads are laid between fibrous fleeces 1a, 1b and between fleeces 2a, 2b by means of an endless belt 5 carrying bobbins 6 revolving round the fleeces 1a, 2a. Initially, the threads are kept out of contact with the fleeces by moving guide wires 7a, 7b which converge in the vertical plane to deposit the threads on the fleeces; to prevent the threads from becoming slack, the wires travel away from the fleeces in the horizontal plane. Cutters (not shown) cut the threads between the guide wires after the fleeces 1a, 2a have been joined by the fleeces 1b, 2b, the reinforced fleeces are then taken up at 3c, 3f. By providing warp beams between the fleeces 1a, 1b and 2a, 2b, longitudinal reinforcing threads can be fed to the fleeces round the rollers 4a, 4d.

Title: Process for purifying acrylonitrile formed by synthesis from acetylene and hydrogen cyanide
Filed: 1953-12-09
Abstract: Acrylonitrile obtained by synthesis from acetylene and hydrogen cyanide and containing hydrogen cyanide in free and/or combined form as an impurity is purified by treating it with ferrous sulphate in an aqueous alkaline medium made alkaline by addition of a neutralizing substance comprising a basic compound capable of forming a ferrocyanide with the ferrous ion and hydrogen cyanide, preferably a hydroxide, carbonate, or bicarbonate of sodium, potassium, ammonium, barium, calcium, strontium, or magnesium.  The neutralizing substances may be employed alone or in admixture.  The treatment may be effected at about 20 DEG  to 70 DEG  C. and preferably at below 40 DEG  C.  Two layers are formed in the process, an upper layer containing purified acrylonitrile and a lower aqueous layer containing the ferrocyanide formed together with some acrylonitrile which may be recovered by azeotropic distillation.  When part of the hydrogen cyanide is present in combined form as lactonitrile the acetaldehyde remaining in the purified acrylonitrile is readily removable by distillation.  In examples acrylonitrile containing 2.5 per cent acetaldehyde is placed in a vessel provided with a reflux condenser and ferrous sulphate solution followed by sodium hydroxide solution added, the temperature being maintained at 20 DEG  to 40 DEG C.  Acrylonitrile is recovered from the two layers formed; (2) and (3) as in (1) except that an aqueous solution of potassium hydroxide and of calcium oxide respectively are used instead of the sodium hydroxide solution.

Abstract: 155,206. McBride, J. P. Aug. 14, 1918, [Convention date]. Cramps.-A device lor clamping together plates to be riveted, or other objects, comprises an hydraulic cylinder having a projecting piston provided with means for engaging behind the plates or for engaging a bolt passed through holes in the plates and clamping them together against the end of the cylinder or an interposed distancepiece. In place of a piston-rod moving in a cylinder, a rod sliding in a housing can be employed, the rod being operated in any suitable manner. As shown in Fig. 1, the piston 3 of the single-acting cylinder 1 has a rod 4 with a projecting threaded end 6 adapted to be passed through holes in the plates 10, 11 and on which nuts 7 may be placed to clamp the plates against the cap 5 of the cylinder when fluid under pressure is admitted through the pipe 8 and valve 9. In a modification, the cylinder is double acting, its ends communicating by ports and valves with either side of the hand-operable piston of a pressure-pump at the side of the cylinder.

Title: Improvements in speed indicators and recorders
IPC: G01P3/10
Filed: 1936-12-18
Abstract: 471,090. Speed indicators and recorders. ATELIERS VAUCANSON. Dec. 18, 1936, No. 34842. Convention date, Dec. 21, 1935. [Class 106 (iii)] In a speedometer of the periodic - counter type, the ratchet-wheel 1, which is given an angular displacement proportional to the average speed during a fixed time period, is driven alternately by two pawls 37, 38 one of which drives while the other moves backwards. The two pawls are operated through rollers 42, 43 and levers 35, 36 by two offset cams 40, 41 on a shaft 39 driven from a wheel of the vehicle. A pin 48 on one pawl engages a slot 49 on the other pawl so that the pawls have independent movement backwards and forwards but are always simultaneously engaged and simultaneously released. At the end of the time period a cam 24 rigid with an escapement wheel operates a lever 16 which acts on a pin 53 to lift both pawls 37, 38. The engagement of the pawls is similarly effected by a lever 14 and a pin 52. A pawl locks the ratchet for a short time before a new measuring period begins. By means of contact pins 3, 7 a ratchet 5 is caused to follow the displacement of ratchet 1 until the end of the measuring period, when it is held by a pawl during a subsequent period. A contact pin 8 on the ratchet 5 displaces an arm 9 rigid with a shaft 2 to operate the pointer. Shocks in the transmission are deadened by inserting a spring coupling in the drive between the pointer spindle 58, Fig. 6, and the rack 60 operating the recording style 63. 'This coupling includes a member 64 engaging a pivoted spring-urged lever 65 moving between pins 67, 68 on a toothed wheel in the drive.

Title: Link mechanism actuated by pivoted lead screw having a plurality of nuts thereon
IPC: B60N2/02
Filed: 1955-12-06
Abstract: 808,025. Screw-and-nut gearing. AMERICAN METAL PRODUCTS CO. Dec. 6, 1955 [April 18, 1955], No. 34997/55. Class 80 (3). [Also in Group XIV]  A screw and nut mechanism for operating two separate means either independently or together is particularly applied to the power operation of the raising and lowering, and forward and backward movement, of a vehicle seat. A screw 31, reduction gear 29 and a motor 28 are pivoted as a unit about a pivot 32 and a pair of nuts 34, 35 each having a holding device operated by a solenoid 37 co-operate with the screw. The nut 34 is pivotally connected at 38 to the arms 14 of a rock shaft 12 which operates through an arm 16 and a link 17, a bell crank 6, and through a link 19 a further bell crank (not shown) at the other end of the mechanism. The bell cranks 6 are coupled to brackets 8 secured to the seat slide 9 for raising and lowering the same on actuation of the nut 34 by the screw. The nut 35 is pivotally connected at 39 to two links 42 coupled to arms 15 of a rock shaft 13 which operates through an extension 22 of one arm 15 a link 23 coupled to a bracket 24 to the sliding seat frame 11. Thus the seat frame is slid backwards or forwards on actuation of the nut 35 by the screw 31. The pivotal mounting of the screw and driving unit and the link connection 42 to one nut allow the free operation of either or both of the nuts. A third nut may be provided on the screw for operating mechanism for tilting the seat. The nuts 34 and 35 rotate freely with the screw when not held by the solenoids 37 and do not then transmit movement to the operating mechanisms. When the solenoids are operated the nuts are held to transmit the desired movement. The nuts may be released by limit devices at their limits of travel or by overload devices. The mechanism is stated to be also applicable to operating the ventilating and vertically movable windows of a vehicle door.
