Abstract: 817,992. Drying threads &c. BRITISH RAYON RESEARCH ASSOCIATION. April 27, 1956 [May 10, 1955], No. 13576/55. Class 34(1) Filaments, threads &c. are dried by passing in long lengths through a hot bed 11 which is fluidized as described in Specification 773,598. The ends of yarn 12 are arranged in parallel and passed through the bed 11 over rollers 13, 14, 15, 17. The bed comprises sand, fluidized by air which enters via a pipe 23 and passes through a porous ceramic partition 23a and heated by thermostatically-controlled electric heating elements 24. Fluidizing air is also supplied to the ceramic roller 14 through an air seal as is described in Specification 800,091 [Group VIII]. The dried yarn is collected on the roller 17 which is driven by a motor 19 through a variable speed gear 18 and a roller 16, adjustment of speed being dependent on a meter (the plates 22 of which are shown) which measures the moisture content of the yarn as it leaves the bed. Combs 20 preserve the spacing of individual yarns and immediately prior to leaving the bed the yarns are subjected to the vibrations of a suitably driven vibrator rod 21. When drying dyed or processed filamentous material the fluidizing gas may be such that it assists chemically in the dyeing &c. of the material. The bed particle size may be between 100 and 200 microns, the bed temperature between 100 and 175‹C. and the fluidizing air velocity between 0.5 and 2 ft. per sec. The space occupied by the bed may be sub-divided by wire grids and the moisture-laden gas from the bed may be used for pre-drying the wet material. The material may be fed to the bed, which as an alternative to electricity may be heated by gas-fired or steam-heated pipes, on belts, gauzes or felts.

Filed: 1928-05-09
Abstract: 316,696. Marchetti, P. May 9, 1928. Cam-actuated pumps.-Means for converting reciprocating into rotary motion and vice versa, for driving gears of internal combustion engines &c., comprises two pistons or purely reciprocating members co-operating with two rotary cams through two rollers &c. riding thereon, each roller being connected to its piston through a connect. ing rod and being guided by a radius arm, the two radius arms being interconnected so that the rollers are maintained in contact with the cam surfaces. As applied to a radial cylinder engine Fig. 3, the pistons 3 are associated in pairs, the connecting rods 5 carrying rollers 6, 6<1> riding on elongated cams 4, 4<1> shaped and relatively set according to the piston accelerations &c. The rollers are constrained by radius arms 7 on pivots 8, 8<1>, extensions of the arms being coupled by a link 10. In a modification wherein the cylinders are not equally spaced, single pivots serve for adjacent radius arms of respective pairs. In the arrangement shown in Fig. 4, in which the cylinders 1 are parallel and the cams 4 are arranged at right angles, the piston stroke is greater than the cam throw, the rollers 6 being carried by the arms 7 between the pivots 8 and the points of connection 11 to the connecting rods 5. Alternative means for interconnecting the radius arms 7 comprise links coupling their outer ends of a centrally pivoted lever. Specification 310,632 is referred to.

Abstract: 312,154. Spiess, G. May 21, 1928, [Convention date]. Pile - supports for sheet feeds. - In a sheet-feeding machine of the kind in which the sheets are fed automatically from a pile supported by chains passing over sprockets 8 at each side of the pile, the sprockets 8 are driven by worm gearing to raise the pile, and can be operated by hand-wheels 78 at either side of the pile, or by gear wheels 13. Fig. 2, gearing with wheels 14, 14<a>, either or both of which can be put into driving - connection with a sliding-shaft 17 driven by bevel-gearing and universal connections from an electric motor 21, or both of the wheels 14, 14a may be put out of operation in order that the raising of the pile may be operated by pawi- and-ratchet mechanism 50, 51, 53, 54, 55, Fig. 3, operated by a cam-shaft 71 and lever and link mechanism from the sheet-feeding machine. The required means for raising the chains is put into gear by operating a hand-wheel 23, Fig. 3, which is provided with a gear 25 geared to a rack on the shaft 17, and spring-controlled keys 27, Fig. 5, pivoted to shaft 17 can engage slots in the gears 14, 14a to couple the gears to the shafts. As shown, the right-hand key engages gear 14, and gear 14<a> is free. By moving the shaft to the right, both gears 14, 14<a> are freed from shaft 17, and in this position of the wheel 23, a cam 44 permits a curved lever 48 to free the spring-controlled pawl 50 of the automatic raising mechanism, and this can operate. In other positions of the shaft 17, both gears 14, 14a are coupled to shaft 17, or only the gear 14a is coupled. The adjustments of wheel 23 are controlled by a click pin 36 engaging recesses 34 in the hub of the wheel, and a series of similar recesses 38 permit a locking-pin 37 to engage and hold the wheel. This pin 37 is part of an armature of an electromagnet which is raised when a switch in the circuit to the driving motor 21 is closed, and the circuit can only be completed if the armature is raised. The raising of the electromagnet armature breaks the circuit in a relay coil which normally locks the starter of a controller for the driving motor, and the current can be varied after the raising of the armature.

Title: Improvements relating to braking-light systems for vehicles
IPC: B60Q1/44
Filed: 1969-03-17
Abstract: 1,213,964. Road traffic signals on vehicles. DAIMLER-BENZ A.G. 17 March, 1969 [18 March, 1968], No. 13771/69. Heading G4Q. In a braking light system switching means automatically varies the brake light indication in the same sense with diminishing vehicle speed and increasing brake pressure. The brake light indication may take the form of an increasing area which is illuminated and/or an increase in the intensity of illumination. With an ignition switch 5 closed and accelerator 8 and clutch 10 released to close contacts 7 and 9 all three brake lamps 2a, 2b, 2c are lit via contacts 13a-13c, 12a-12c of a centrifugal switch 11, 14. When the vehicle is moving in a low speed range (Vu, Fig. 2, not shown) all the contacts 13 and 12 remain closed to illuminate all the lamps 2a-2c provided the accelerator and clutch are released. When the vehicle is moving in a middle speed range (Vm) the centrifugal switch moves sleeve 14 in the direction 15 so that contacts 12b and 12c contact contacts 13a and 13b respectively so that provided switches 7 and 9 are closed only lamps 2a and 2b are lit. In the highest speed range (V o ) only contacts 12c and 13a are closed to illuminate only one lamp 2a when the accelerator and clutch are in their release positions, so that the speed range at which the vehicle is travelling is indicated by the number of lamps lit. Also associated with the sleeve 14 are contacts 16-19, 26-29 operated from a piston 35 driven by the hydraulic brake 23 of the vehicle. The pressure applied to the brake 22 determines the amount the piston-rod 32 and contacts 26-29 rise and the amount of illumination. For light, middle and high pedal pressures (Pu, Pm, Po) lamp 2a, 2a, 2b and 2a, 2b, 2c respectively are lit. A brake operated switch 24 is connected in series with the switch 16-19, 26-29. The brake pressure switch actuator 32-36 may be replaced by a single switch (38, Fig. 3, not shown), operated by the brake device 23 to sequentially connect via lines (39, 40) the increasing number of lamps to be illuminated as the brake pedal pressure is increased as above. The clutch switch 9 prevents the brake signal being given when the clutch is depressed for gear changes. After continuous or stepwise increase of the area illuminated or of the intensity of illumination, flashing of the brake light on and off may be produced, and the rapidity of the flashing may be increased with diminishing road speed.
