Filed: 1955-05-27
Abstract: 782,604. Headlamps. PALLAS, G. May 27, 1955, No. 15463/55. Class 75(4) An anti-dazzle device for downwardly deviating the light from car headlights comprises a stationary vizor 1 connected at one edge to the rim of a headlight, a movable vizor 10 swingably mounted on the stationary vizor and means for controlling the movable vizor. The stationary vizor 1 is of segmental shape and its upper perpendicular edge 3 is clamped in the bezel of the headlight. The movable vizor 10 is of similar shape and is swingably mounted on pins 11 projecting from the stationary vizor 1. The movable vizor includes a translucent lens 15. The upper edge 9 of the movable vizor abuts a flange 12 on the lower edge of the stationary vizor in the non-overlapping position of the vizors and a rubber band 14 secured to the lower edge 13 of the movable vizor 10 abuts the flange 12 in the overlapping position of the vizors. The movable vizor is moved by a cable located in a groove 5 in the stationary vizor and connected to the stem 7, Fig. 5, of a piston 17 slidably mounted in a cylinder 16. Channels 18, 19 extend from the bottom and top of the cylinder to open into a transverse bore in a member 42 closing the lower end of the cylinder. The bore contains a sliding cylindrical valve 22 having two spaced end grooves 20, 21 and a central groove 23 communicating with a bore 24 ending in the plane of the two end grooves 20, 21. The central groove 23 is in constant communication with a pipe 25 leading to a source of pneumatic pressure such as the inlet manifold or the exhaust pipe of the car engine and the two end grooves 20, 21 are open to atmosphere. In one end position of the valve the channel 19 communicates with the end groove 21 whilst the channel 18 communicates with the central groove 23 and in the other end position the channel 19 communicates with the central groove 23 and the channel 18 with the end groove 20. The piston therefore moves from one end of the cylinder to the other with change of position of the valve. The valve is moved by coils 29, 30 housed in the closure member 42 and energized by a two way switch. The valve is prevented from rotating by a pin extending through the closure member 42 into a guiding slot in the 'valve. The valve is lubricated by a spring pressed plug located in a bore in the closure member 42. Air filters 45<SP>1</SP> are mounted in the ends of the bore in the closure member 42. The piston is made of rubber and is packed with lubricant which passes through a bore 37 into a peripheral groove in the wall of the piston.

Title: Improvements in and relating to dough brakes and to the preparation of dough for biscuit cutting machines and the like
IPC: A21C9/08
Filed: 1942-11-03
Abstract: 563,527. Dough breaks. WILSON, G. D., HART, J., and BAKER PERKTNS, Ltd. Nov. 3, 1942, No. 15504. [Class 87 (ii)] To allow gravity to aid in feeding the dough back and forth between the rolls, tables are pivotally mounted on both sides of the rolls. In the form shown the tables 1, 2 are fixed to bosses 23 on a framework 3 comprising side frames 4 connected by a cross-head 6 and rods 5. The framework 3 is pivoted in bearings 9 in the machine base 11, and the shaft 12 of the lower roll 8 is journalled in bearings 13 in the framework 3 and bearings 16 in the base 11. The framework 3 is rocked on its bearings 9 by a reversible electric motor 30 which turns a screw 28 coacting with a nut 29 secured in a counterbalance weight 27 fixed on the lower ends of levers 24, 25 fixed to the framework 3. Alternatively the drive for tilting the table may comprise segment and worm gear, or a crank and link motion. The motor tilts the framework, and hence the tables, to the broken-line positions shown. A pair of push buttons control the operation of the motor 30 ; if they fail, a sleeve 32 or 33 engages a buffer 34 or 35 to stop the tables. Limit switches controlling the motor 30 may be engaged by the levers 24, 25 at either limit of their travel. Brakes bring the tables to rest. Each table may include a manually- or mechanically-operated turntable 37 having four 90-degree spaced slots engageable with a catch 39, whereby the dough may be turned through 90 degrees before being fed back to the rolls. The rolls 7, 8 rotate only when the tables are inclined; in this position of the tables a pin 49 on a lever 24 engages a clutch lever 48 to engage a clutch in a gear-box 42. When the tables are horizontal the clutch is out. The tables may pass from one inclined position to the other, or may stop at an intermediate horizontal position. In modifications (1) a single table may be mounted between side frames and have a transverse slot through which the lower of a pair of rolls operates, and the bearings may be of a knife-edge character, and (2) separate tables may be independently tiltable. The improved dough break may be located between a dough sheeter and a series of biscuit gauging rolls of progressively decreasing clearance.

Title: Method and apparatus for the upward current separation of particles
IPC: B03B5/62
Filed: 1951-07-02
Abstract: 709,127. Upward-current separators. MAATSCHAPPIJ VOOR KOLENBEWERKING STAMICARBON, N.V. July 2, 1951 [July 5, 1950], No. 15661/51. Class 82 (2) [Also in Group XXIX] A constant upward current velocity is ensured in an upward current separator by maintaining constant the principal current-producing force, e.g. the force exerted by a liquid head or pump and introducing into the upward current a gas which rises in and increases the velocity of the upward current and escapes from the surface thereof, the rate of supply of the gaseous medium being automatically varied in dependence on the liquid level in the separator. An upward current is produced in the vessel 2 by means of a propeller 4 in the pipe 3; material to be separated is introduced at 1; sinks are removed by the elevator 5 and floats pass over the overflow 6 and screen 7 to the discharge 8; liquid passes through the screen 7 into the pipe 3; and air is introduced into the vessel 2 through the pipe 20. The air supply to the pipe 20, from a compressed air source, is controlled by the diaphragm valve 18, the annular space 17 of which communicates through the pipe 16 with the bore 13 of a rotating valve, the rotary bushing 12 of which is connected by the arm 10 to the float 9. Radial ports are provided in the gudgeon 11 and bushing 12 of the valve and the pipe 16 is connected to the compressed air source through a throttle valve 19. Thus, as the height of liquid in the vessel 2 falls, the bushing 12 is angularly displaced so that air from the pipe 16 can escape through the radial ports in the parts 11, 12, so reducing the pressure in the space 17 and allowing more air to pass through the pipe 20. The float 9 may be replaced by electrical contact devices or air bubbling devices or the float may be connected directly to the regulating member.

Title: Improvements in sheet printing
IPC: B41F21/08
Filed: 1947-06-16
Abstract: 631,010. Printing-machines. HOE & CO., Ltd., R. June 16, 1947, No. 15864. Convention date, June 14, 1946. [Class 100 (ii)] In a rotary multi-colour printing-machine errors of register due to change in width of the trailing part of a sheet which is gripped by its leading end are prevented by warping the leading end of the sheet as it is advanced to printing position, the warping being produced by bowing the gripper bar. In one form in which the sheets are carried through offset printing couples by grippers 6 mounted on gripper bars 5 carried by supports 10, Figs. 4 and 7, on chains 1 as described in Specification 478,362, the grippers being received in recesses 20 in the impression cylinders 12, the gripper bars are supported at one side by rollers 31 mounted concentrically on a shaft 32 secured in the recess 20, and on the other side by rollers 33 mounted eccentrically on a shaft 34 which extends through the end of cylinder 12 as shown in Figs. 7 and 8, and is connected to a sector 40 having means for adjusting and locking it in positions determined by a pointer and indicator scale 44. The rollers 33 can thus be set to positions indicated by full and dotted lines in Fig. 8, or in intermediate positions, and thus cause a bowing of the gripper shaft to give a forward or rearward movement to the centre of the printed sheet and thus correct errors of register due to slight warping of the sheet in directions causing widening or narrowing of the trailing part of the sheet. In a modification, Fig. 11, as applied to a machine in which sheets are fed to the impression cylinders 104, of a multi-colour offset press by means of transfer cylinders 103, Fig. 9, not shown, means are provided to bend a gripper bar 110 at its centre in an upward or downward direction depending upon whether the printed sheet tends to increase or decrease in width. The bowing movement is dependent upon the setting of a pin 137 concentric to, or on either side of, the pivot of an arm 140 which is oscillated at each rotation of the cylinder 104 by means of a roller 150 which moves over a fixed cam 152. The pin 137 can be moved in a slot 143 in the lever 140 and a scale is provided to aid the setting of the pin. In either form, means may be provided for adjusting the bowing of the gripper bar while the press is running. As applied to the conveyer type of press this may be effected by adjusting a stationary cam over which rolls a roller on a lever arm which adjusts the eccentric rollers 33, Fig. 8, as grippers pass over the impression rollers 12.

Abstract: 801,989. Windscreen cleaners. GRAYCOL DEVELOPMENTS, Ltd. Oct. 3, 1956 [July 3, 1955], No. 15929/55. Class 138(1). A windscreen wiper blade comprises a tongue 5 and side members 6 in liquid sealing contact therewith which together form a channel 7 longitudinally of the blade, the channel being adapted to be opened for exit of liquid fed to the blade by the wiping action of the blade. As described, liquid is pumped under pressure through a tube 1, attached by a clip 3 to the arm of a windscreen wiper, and thence through tubes 8 into channels 7 extending longitudinally of the wiper blade 5. The sides 6 of the channels 7 form liquid seals with the blade 5 when in its central position, but movement of the blade across the screen causes these seals to open alternately thus releasing liquid into the path of the blade. The tube 1 may be incorporated in the wiper arm and not merely attached to it. Also the tube 1 may be connected to one end of the blade, the other end either being closed or having a small jet attached to it to provide a fine spray on the screen. The edge of the tongue 5 may have a bead of circular or semi-circular section to assist the cleaning action.
