Filed: 1946-01-29
Abstract: 607,254. Window opening and closing apparatus. TRICO PRODUCTS CORPORATION. Jan. 29, 1946, No. 2895. Convention date, Jan. 29, 1945. [Class 20(iii)] A window operating mechanism particularly for a vehicle comprises an endless flexible transmission 5 carried by a frame which is foldable to facilitate installing it in the restricted space in the window well. For this purpose the frame comprises a central portion 12 with offset ends 14 to each of which an arm 13 is pivoted, pulleys 11 being provided at the free end of each arm and at each end of the central portion. Guards 16 keep the transmission member on the pulleys. The transmission passes several times around a counterbalancing spring drum 20 and doubles on the intermediate pulleys so as to form two active vertical flights 4 to which the window 1 is attached by lugs 3, there being a resilient connection between the lugs and the flights to compensate for any non- parallelism between the flights and the window guides 2. The spring drum is rotatable in either direction by hand crank 27 and locking means are provided either to prevent rotation of the drum in either direction, otherwise than when the drum is operated by the crank, or to prevent rotation of the drum in the window-opening direction, whilst permitting rotation in the window-closing direction, when such movement is attempted otherwise than by actuation of the crank; the latter alternative permits the closing from outside the vehicle, of a window which has inadvertently been left open but prevents the opening, from the outside, of any closed window.

IPC: B22F3/00
Filed: 1940-02-15
Abstract: 538,803. Moulding powdered materials. WELLMAN CO., S. K. Feb. 15, 1940, No. 2927. Convention date, March 1, 1939. Class 87 (ii) Powdered material, particularly metal powder, is uniformly distributed within a mould by introducing the entire charge into the mould, moving a spreader over and in contact with the charge supporting surface until the entire charge has been churned and mixed and then continuing to move the spreader against the charge while gradually separating it from the surface of the mould. Fig. 1, shows a hand apparatus in which a spreader blade 20 secured to a stem 5 guided within a barrel 2 and adjustable therein by a screw operable by a hand wheel 17. The barrel 2 is carried by a support 1 and is surrounded by a sleeve 19. In use, the charge is introduced into the mould cavity 27 and the blade 20 is lowered to contact with the surface of the mould or of a bottom plate 28a. By means of the sleeve 19 and a knob 23 the device is manipulated to advance the blade along each of the mould walls in succession, while in contact with the bottom surface, until the whole charge has been stirred, after which the hand wheel 17 is turned to raise the blade slightly and a further circuit is made, this process being repeated until the blade is clear of the powder. Fig. 5 shows a machine comprising a turntable 48 supporting mould members 88, 87 which are centred by a pin 50 and annular plate 89 ; a blade 47, fitting the mould cavity, is adjustably secured to an arm 43 carried by a stem 38 adapted to be raised and lowered by rack gear operable by a hand wheel 42 and also adapted to be raised automatically through a crank mechanism comprising a crank disc 65 furnished with an adjustable crank pin connected by a link 68 to a link 70 pivoted at 71 to the framework, the link 68 being also connected by a link 72 to a clamp 74 adapted to be secured to the stem 38 by a screw 75. The crank disc 65 is driven from a motor 57 through a friction clutch and is furnished with stops adapted to engage a fixed stop pin to limit its movement to about 90 degrees. In operation, with the clamp 74 free. the turntable 48 is set in rotation, the mould is charged with powder and the blade 47 is lowered to contact with the plate 89 ; the crank disc 65 is then turned backward until the stop engages the stop pin, the clamp 74 is tightened and the motor 57 started. After the crank has moved through its allotted angle, clamp 74 is released and the blade is raised out of the mould cavity by operating handwheel 42. A separator 91 is lowered into the mould cavity and the process is repeated. When a desired number of layers have been spread, the pin 50 is lowered by means of a lever 51 and the mould assembly is slid off the table 48 and transferred to a press. The blade may be stationary and the mould moved up and down, or the blade may be arranged to rotate within a stationary mould. Specification 537,870 is referred to.

Title: Improvements in or relating to combined harvesting and threshing machines
IPC: A01D41/00
Filed: 1929-01-30
Abstract: 319,566. Jackson, L. Mellersh-, (Caterpillar Tractor Co.). Jan. 30, 1929. Thrashing - machines. - The thrashing mechanism of a combined harvesting and thrashing machine is supported by and enclosed in an inverted U-shaped shell 6, preferably of corrugated metal. Channel tie members 7 and a tie plate 8 extend across the base of the shell to stiffen its construction. Angle iron reinforcing members 9 also extend along the lower sides of the shell. A tubular axle 11 carried by main wheels 13, 14 supports the shell and also balance beams 16 for the header of the harvesting machine. The grain cut by the header is delivered through an opening in the shell on to a conveyer 17 that carries it to a beater drum 22 and concave 23, both these being mounted on the walls of the shell. The grain is discharged past a baffle 24 on to a straw walker consisting of a number of primary shoes 26 and secondary shoes 27. The shoes 26 consist of vertical side pieces 28 having serrations 29. The shoes are raised in turn by eccentrics 32 on a shaft 33 arranged at their forward end. They are supported at their rear end by cranks 36 mounted to rotate on a shaft 37, these cranks being connected to cranks 38 to impart motion to the secondary shoes 27. The grain falls from the shoes on to a shaking screen 42 through which it passes to a screw conveyer 49 that carries it to a similar transverse conveyer 51. This conveyer moves it into a housing 52 in which a rotary impeller and fan works. It is thus forced up a conduit 53 from which it passes on to a double shaking screen 57, being spread over the screen by a screw conveyer 56. The good grain falls into the bottom of a storage bin 58 whence it is carried by a conveyer to a discharge elevator, while the other material falls from the end of the screen through a shoot 71 on to the beater conveyer 17. Fans 72, 73 are used to improve the separation of the good grain at the straw walker and grid 42 and the grid 57 respectively. The machine is secured to a tractor by a device 121 and a railed platform 123 reached by steps 122 is provided for the operator.

Patent GB-372321-A (GB)
Title: Improvements in the manufacture and production of liquid unsaturated hydrocarbons of high molecular weight
IPC: C07C2/00
Filed: 1931-02-02
Abstract: The liquid olefinic products, usually containing between five and eight carbon atoms and prepared by the vapour conversion of low-molecular olefines over certain inorganic anhydrous halides, are stated to be useful for addition to benzines to improve their non-knocking properties.ALSO:Olefines containing up to five carbon atoms are converted into liquid olefines of higher carbon content by passing them in the vapour phase over inorganic anhydrous halides which volatilize at temperatures of 100-800 DEG  C.; the temperature must not exceed 300 DEG  C. and in any case is below the volatilization temperature of the catalyst, whilst the duration of contact of the vapour with the catalyst lies within the range 0,5 to 100 seconds.  The olefinic starting material may comprise the mixed products obtained by dehydrogenation of the corresponding paraffin hydrocarbons, or by cracking paraffin or naphthene hydrocarbons, e.g. paraffin wax, ceresin, heavy and middle oils, paraffin oil and petroleum fractions, or by the low temperature carbonization of shales and coals.  Inorganic halides specified are the chlorides, bromides, iodides, or fluorides of aluminium, tin, antimony, iron, zinc, cobalt, and copper, which may be employed alone or in admixture or mounted on carriers.  Atmospheric pressure is usually employed, and the olefine vapour may advantageously be saturated with water vapour.  The products usually contain between five and eight carbon atoms and may be added to benzines to improve their non-knocking properties.  Examples are given in which mixtures of olefines, comprising mainly ethylene, propylene, and butylene, are passed over aluminium chloride, or a mixture of aluminium and cobalt chlorides, cobalt and copper chlorides, or aluminium and ferric chlorides. Specifications 255,493, 316,951, and 326,322, [all in Class 2 (iii), Dyes &c.], are referred to.
