Abstract: 181,067. Carmichael, T. B., and Ockleston, W. H. Feb. 24, 1921. Combination tanning processes; chrome tanning.-Hides are tanned by a combination process which consists in treating the limed hides after washing either successively or simultaneously with an acidified green chrome liquor and a vegetable tanning-liquor. When the solutions are used simultaneously, the hides may be further treated with a vegetable liquor or with a series thereof in increasing strengths. The chrome liquor is prepared by dissolving green chrome salts in water to make a solution of 20‹ Barkometer, to which is added sufficient acetic acid to render 20 c.c. of saturated lime-water necessary to neutralize 10 c.c. of the liquor. After treatment in the chrome liquor, the hides are drained and then placed in a vegetable tan liquor of about 80‹ Barkometer or in a floating drum immersed in a vegetable liquor of 80‹-90‹ Barkometer, and finally in a liquor of 150‹ Barkometer at a temperature of 100‹-120‹ F. In the combined bath equal proportions of the acidified chrome liquor and a vegetable liquor of 30‹-40‹ Barkometer are used. According to the Provisional Specification, the chrome liquor is acidified with sodium bisulphite.

Title: Improvements relating to presses for the production of bricks, briquettes, blocks and the like
IPC: B30B1/14
Filed: 1923-03-06
Abstract: 218,703. Sutcliffe, E. R. March 6, 1923. Hopper-and-plunger machines; rotary-table machines.-In a press of the hopper and plunger type for moulding briquettes from fuel, concrete, &c. a single mechanism compresses the material in two or more stages within a stationary mould, and the consolidated briquette is ejected by extending the stroke of the plunger beyond that necessary to compress the charge. The latter is compressed through toggle mechanism and the reaction thereto is resisted by means operating under fluid pressure. The combined hopper and mould e, f is mounted on fixed supports on the machine base a. The mould tapers towards the discharge end and may be slotted or formed as shown in Fig. 3 to allow the escape of moisture from the charge. The material is compressed between a plunger g sliding in the mould and an abutment b<1> held in position by a cross-head b, space being allowed so that at least three briquettes are under compression at one time. The cross-head b is rigidly connected by means of bolts d with another cross-head c, and is pivotally supported on a link a<1> and bracket a<3> so as to be reciprocable horizontally under the action of the compression mechanism. The plunger is supported by a slide block h moving in a bearing h', and pressure is transmitted thereto through a link i<4> by a bell-crank lever i<3>. The latter is pivotally supported on a pivoted link a<2> and is operated to compress the briquettes by a crank rod i<2> recprocated from a shaft i driven by a gear wheel l. The extent of the movement of the plunger is governed by a hydraulic ram j fixed to the cross-head c and pressing against the part k of the bell-crank lever i<3>. After the compression, the stroke of the plunger is extended to eject the moulded block by a forward movement of the ram j under action of a cam race l<1> formed on the gear wheel l thus operating links and levers P, l<4>, l'. The abutment b<1> is pivotally suspended from the hopper f and a striker bar and scraper is similarly mounted to strike off the ejected briquette. A modification is described in which the briquettes are compressed in a series of moulds formed in a vertical rotary-mould-table and in which the cross-head b is fixedly mounted on the machine base. Specifications 20679/14 and 209,794, [Class 50, Fuel, Manufacture of], are referred to.

Title: Rotor head fairing for articulated aircraft rotor
IPC: B64C27/50
Filed: 1967-02-13
Abstract: 1,127,887. Helicopter rotor heads. UNITED AIRCRAFT CORP. 13 Feb., 1967 [24 Feb., 1966], No. 6708/67. Heading B7W. A fairing 100 for an articulated rotor head comprises a rigid member 102 fixed to the rotor head and having a cut-out 118 for each blade 50, and round each blade two sleeves 104, 106 forming two socket joints 190, 200, one between the cut-out 118 and the sleeve 104, and the other between the sleeves, sleeve 106 ending in close proximity to the blades. Blade movement.-The blade may pivot about flapping axis 34 and lead-lag axis 32 of the universal joint 30, 36, and about the feathering axis 52, due to the rotation of sleeve 42 about member 40. The lead lag motion is controlled by damper arm 70 and cylinder 72. Pitch change motion is controlled by movement of arm 68, by lever 62, and link 60 which is in turn controlled by a swash-plate (not described) to produce cyclic and collective blade pitch. Fairing movement.-Sleeve 104 is carried by pins 140 on member 102 and is free to pivot about axis 33, thereby allowing for the lead-lag movement of the blade, the interface at socket joint 190 being shaped to facilitate this movement. Sleeve 106 is carried by blade member 40 at 182, and therefore moves with the blade about the lead-lag and flapping axes, but not about the feathering axis. The interface at socket joint 200 between the sleeves is shaped to allow relative movement (flapping) about axis 34. The use of two sleeves provides a sleeker fairing than one with a single spherical socket joint. Blade folding.-The blade 50 may be carried by a bracket 44 mounted on the sleeve 42 by two bolts 47, 49, so that by removal of bolt 47, the blade 50 and bracket 44 can be folded about bolt 49. In this case there may be a further fairing sleeve 108 carried by member 42 comprising a fixed portion 250 and two portions 256, 258 which can be pivoted about hinges 260, 262 to allow the blade to be folded. There may be a further fairing sleeve 110 fixed to the blade.

Title: Improvements in or relating to harvesting machines
IPC: A01D34/24
Filed: 1965-02-26
Abstract: 1,106,002. Combine harvesters. TEXAS INDUSTRIES Inc. 16 Feb., 1965 [26 Feb., 1964; 3 June, 1964], No. 6715/65. Heading A1F. [Also in Division B5] A combine harvester comprises two mowing table portions 14 each including a frame consisting of members 29-32, and 34 (Fig. 4) and 33 (Fig. 7), each frame member 29 being pivotably connected by pins 24, 25 to one side of an elevator housing 15, so that the corresponding portion may be raised by hydraulic cylinders (108) (Fig. 6, not shown) to a substantially vertical transport position. Vertical adjustment of the portions together with the elevator housing about shaft 17 (Fig. 7) is effected by hydraulic cylinders 114. Adjustment of the mowing table height and of height of reels 48 is affected by hydraulic cylinders (64, 51) (Fig. 11, not shown). The hydraulic control includes a lever 124 (Figs. 9 and 10) and associated cam discs 127, 128 engaging valve-operating sliding rods 135, 131 respectively. With the lever 124 in the position shown valve 130 is open and communicates with valve 118 and valve 129, which is identical to valve 118, is closed. A feeler member 68 when it engages ground irregularities operates the valve 118 through linkage 70, 71 and thus causes fluid to be introduced to or exhausted from cylinders 114 so that the height of the mowing table shall remain constant. When the lever 124 is moved to the left the valve 130 is closed and valve 129 opens to allow fluid to pass from pump 121A to the cylinders 114 to raise the mowing table. The cam 127 includes a portion which causes the valve 129 to close when the lever is located in part 125 of sector plate 126 so as to hold the mowing table in an intermediate position. The cam 127 is so shaped that when the lever abuts element 125A the valve 129 is opened so as to permit fluid to pass from the cylinder 114 to the reservoir 121, thus the mowing table is lowered. The hydraulic cylinders (51, 64) and (108) are controlled by valves (158, 133, 151) (Fig. 11, not shown) each being identical to the valve 118 and each being connected to the reservoir 121 and pump 121A. Cutter bars 54, augers 55, and reels 48 are driven from gear boxes 75 via telescopic shafts, gear boxes 84, shafts 85 and gear boxes 86. The portions can be locked in their vertical or horizontal positions. In a further embodiment (Figs. 1-3, not shown) the mowing table portions are pivotally mounted on a single forwardly extending substantially horizontal shaft.
