Abstract: 786,855. Piling textile tows. IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 29, 1955 [July 16, 1954], No. 20768/54. Class 120(3) A tow of filaments is laid in a stationary container by first being fed on to an advancing reel that carries loops of tow by means of radially projecting wheels or bars which pass the tow along the reel to drop off into the container. In one embodiment, tow is passed through a tube 30, the introduction being assisted by an air jet. and laid on the reel 33 so that the coils are held by the teeth of wheels 40, 41. Six similar wheels are radially arranged round a worm gear 39 on a shaft 38 rotatable with the tube 30 and are rotated by the shaft to lower the coils of tow until they fall off into a container. The reel 33 is preferably constrained from rotating with the shaft 38 by gearing comprising a stationary toothed annulus 34, planet wheels 35, 36 keyed on a shaft 47 and a gear wheel 37 attached to the reel 33. By suitable choice of gear ratios, the reel 33 may remain stationary or rotate slowly in either direction. By attaching the device to a pantograph mechanism the coils of tow may be laid in the container in a variety of patterns permitting later removal without tangling. Another form of reel rotates around a stationary shaft and toothed radially - arranged wheels gear with a worm on the stationary shaft. The reel is surrounded by a tubular deflector plate with a slot in the top which permits laying of the two on the toothed wheels. If the reel must haul tow from a fixed speed machine, it may be driven by a compressed air motor or constant torque electric motor. A constant speed electric motor may be used if tow is available at an unlimited speed.

Abstract: 964,394. Feeding and delivering sheets. R. HEPP. May 30, 1962 [June 1, 1961], No. 20786/62. Headings B6B and B6H. A method of collating sheets comprises the steps of displacing a plurality of sheets folded along a line in a predetermined direction parallel to said line along a transport path, partially unfolding said sheets, and depositing a second sheet upon each of said first-mentioned sheets by displacing said second sheet above said first-mentioned sheet in said predetermined direction at the speed of said first-mentioned sheets. Folded sheets A, Figs. 2 and 4, are fed in succession from the bottom of a pile by a feed drum carrying rotating suction rollers 2 on to a table where they rest until engaged by abutments 4 on chains of a conveyer 3. The number of sheets moved along as a pile by each pair of abutments is controlled by a variable-speed clutch 5 determining the relative speed of the feed drum and the conveyer. The abutments convey the sheet or pile of sheets to an unfolding device comprising chains 10, 35, Fig. 5, moving at the same speed as the conveyer 3 and carry - ing suction heads 8, 34. The upper flap of the sheet is raised to clear an unfolding tongue 15 and a guide plate 9 then opens the sheet so that one flap is vertical, in which condition the sheet approaches a collating station whereat sheets from a stack B are deposited by a feed drum arrangement the same as that shown in Fig. 4 on chains 19 having abutments which pass them between a drum 22 and synchronously moving band 24 so as to approach the sheet on the conveyer 3 while moving at the same horizontal speed. In another form, Fig. 8, sheets J are deposited on the sheets on the conveyer 3 in varying positions, i.e. adjacent the front or rear thereof, passing between a drum 30 and band 32 and then between a drum 33 and similar band. The sheets are fed at the desired times by a swinging suction arm 29 controlled by a cam. The assembly of sheets then passes beyond the plate 9 and the vertical flap is replaced by a plurality of blowers. The suction to the head 8 may be cut off, rendering the plate 9 inoperative, so that sheets B are deposited on unopened sheets A.

Abstract: 1355767 Cooling IC engines J L GRATZMULLER 5 May 1972 [13 May 1971] 20934/72 Heading F4U  I.C. engine cooling device comprises a pressurized liquid cooling circuit, the circuit being adapted to be pressurized by a compressed air reservoir connected to the upper part of the circuit by a conduit fitted with units to regulate the pressure in the circuit and an automatic cut-off valve which is responsive to the pressure in the reservoir and which closes when the reservoir pressure falls to a minimum predetermined value. The engine block 1 is connected by flow and return pipes 2, 4 and 6 to a radiator 3, and a header tank 7 which is connected by a conduit 16 to .the pressurized air reservoir 12 for the vehicle braking system. Pressure in the reservoir is maintained by an engine driven pump 13 and pressure regulator 14. In the conduit 16 there is a reducing valve 19 which opens only when the pressure downstream of the valve falls below a predetermined value, and a valve 18 which is sensitive only to the difference in pressure upstream and downstream of the valve and which also includes a flow limiter 23. The valve 17 is an automatic cut-off valve, the valve member 20 of which is carried by a diaphragm 21 having one surface exposed to the pressure of the air in the reservoir and the other surface open to atmosphere and biased by a compression spring 21<SP>1</SP> to move the valve member 20 to the closed position. The valve is arranged to close as soon as the reservoir pressure falls below the pressure P/2 at which the pump 13 is started by the regulator 14, thus preventing a loss of pressure from the reservoir to the cooling system if the reservoir pressure is below the value P/2. The cooling system pressure is always lower than the pressure P/2.
