Title: Improvements relating to hydraulic rams for tipping gear for lorries and other vehicles
IPC: B60P1/16
Filed: 1934-05-26
Abstract: 430,206. Tipping vehicles. SUNSALOON BODIES, Ltd., and PEARSON, D. A., Weston Lane, Greet, Birmingham. May 26, 1934, No. 15713. [Class 108 (i)] In hydraulic tipping-apparatus for vehicles the movable part of the run is latched against accidental displacement, the securing means being unlatched by means of the pressure fluid at the commencement of the tipping operation. The hydraulic tipping apparatus comprises a series of telescoping cylinders mounted on the chassis by means of a ball foot c and cup. The pressure fluid enters by means of conduits j, h, g, f, e. In the ball foot c a passage m is provided communicating with a rigid cylinder n having a piston o and rod p the end of which contacts with a latching rod s provided with an adjustable hook u adapted to engage over a shoulder v on the outermost tipping cylinder b. On admission of pressure fluid for tipping purposes the piston o is operated causing the latching rod s to be moved aside. A spring w is provided. In a modification the cylinder n is formed in the cup d and its piston p engages with a lug l on the pivoted latch rod s.

Title: Improvements in arrangements for polishing and removing dust from cereals
IPC: B02B3/04
Filed: 1937-06-09
Abstract: 492,992. Polishing and scouring cereals. POLLAK, J. E. (Ges. f³r Neuzeitliche Bodenbehandlung) June 9, 1937, No. 15993. [Class 58] To remove dust from and to polish grain, the grain is fed into the chamber between a casing 2 and a rotary drum 1, the part of the casing concentric with the drum being formed with inwardly directed projections 5, these projections extending parallel to the axis of the drum and extending along its entire length and the drum being provided with driving elements 4. The upper part of the casing is enlarged to form a space 9 into which the grain is thrown by the elements 4, this space being provided along its entire length with an air inlet aperture 7 and an air outlet aperture 8. Guide plates 12, 15 carrying adjustable deflectors 13, 16, are arranged near the air inlet and direct the grain fed into the machine to the space between the drum and the casing. The projections 5 have a gradually inclined front surface and a radially directed rear surface, the rear surface being provided with apertures 6 through which coarse particles fall to a worm conveyer in a collecting chamber 18. The driving members preferably consist of sheaths of emery in cement binders on cement surrounding steel elements detachably secured to the drum, the members being arranged in staggered relationship and being of streamlined cross-section. The elements may also have differing degrees of roughness and be arranged so that the grains on entering the housing are treated by those giving the greatest frictional action. The grains having passed along the casing are collected in a hopper at its end. The dust-laden air may pass through a cleaning chamber and then to a dust separator.

Title: An automatic closing device for doors
IPC: E05F3/10
Filed: 1955-06-06
Abstract: 801,803. Door-operating appliances; spring catches. EVENSEN, S. B. June 6, 1955 [June 5, 1954], No. 16098/55. Classes 44 and 65(1) A floor spring is provided with locking means adapted to retain the door in the closed position. The door spindle 27 carries a crank 26 pivoted at 25 between a pair of lugs 24 projecting forwardly from a cylinder block 21, the rear end of which is provided with rollers 22 disposed within a recess 23 formed in a U-shaped frame 20 mounted within a casing 15. The forward end of the cylinder block contains a piston 28 carrying a roller 29 which is urged by a spring 32 into a notch 30 formed in crank 26, to hold the door in the closed position. The cavity for piston 28 contains an inlet valve 36 and a throttled outlet valve 33, whereby displacement of roller 29 from notch 30 is further resisted by hydraulic checking. The rear end of the cylinder block contains a piston 38 pivoted at 39 to casing 15, the piston cavity containing an inlet valve 37 and throttled outlet valves 34 and 35. Opening movement of the door thereby withdraws piston 38 and slides frame 20 in the casing to compress two springs 18. The final opening of the door, between 80 and 110 degress from the closed position, is checked when the engagement of roller 29 with the straight side of the crank serves to push piston 28 further inwardly. Closing of the door is effected by the springs 18, the movement being hydraulically checked by the valves 34, 35, and final closing being checked by valve 34 alone. The cavities for pistons 28 and 38 do not communicate with each other.

Abstract: 764,845. End-testing cigarettes. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd. Aug. 26,1955 [June 1, 1954], No. 16158/54. Class 130 Cigarettes in flutes of an intermittentlymovable drum conveyer 15 are successively halted in alignment with a test feeler 79 which, if they are soft at the adjacent end, allows its three-armed support lever 75 to move sufficiently under the action of a slidable counterweight 84 to close switch contacts 83, 87 and actuate 'a solenoid 42 to pivot a portion 20 of a conveyer shield against spring action and discharge the corresponding cigarette via a ramp (not shown) to a receptacle, a delay relay ensuring that the portion 20 remains pivoted until a cam 73 disengaging the feeler 79 between tests is operative. Cigarettes undischarged by this testing mechanism and by a following like mechanism 74, 37, 21 co-acting with their opposite ends are later discharged to a receptacle (not shown) via a belt conveyer. The cigarettes are delivered to the conveyer 15 from a hopper having at its exit a refuser roller. During each testing, the cigarettes abut a corresponding stop 101 which may be stationary apart from a screw adjustment but as shown is mounted on a lever 102 counterweighted at 103 to cause the cigarettes also to abut the opposite conveyer shield side flange 16 so that the cigarette length does not affect the test result. The cams 73 are driven via bevel gearing from a motor and reduction gear (not shown) also powering the belt conveyer and refuser roller and, through an eccentric and ratchet drive, stepping round the conveyer 15, which is positioned during testing by spring detents engaging holes in one end face thereof. The third arms 82 of the levers 75, 74 may act as scale pointers or carry recording pens. Each feeler 79 is adjustable along its arm 78 to act centrally on cigarettes of differing diameter. Operation of the solenoids 42, 37 may actuate a counter. According to the Provisional Specification, the feelers 79 are one drum step apart.

A sheet of glass 1 is shaped and tempered by bringing the sheet in a pliable condition between two discontinuous surfaces each formed on a shaping element 4 and movable towards and away from each other, interposing a continuous surface 8<SP>1</SP> between each face of the sheet and the respective discontinuous surface, moving the shaping elements towards each other to shape the sheet therebetween, moving the shaping elements apart, displacing the discontinuous surfaces, and projecting a chilling medium on to the shaped faces of the sheet through the discontinuities 10 in the surfaces of the shaping elements. The surfaces 4 are apertured at 10 and form the front walls of air boxes 5 carried by stirrups 6<SP>1</SP> rigidly connected to rods 6 associated with the power means by which the boxes are reciprocated. Air is supplied to the boxes through connections 7. The continuous surfaces are either formed from a substantially non-combustible material or are provided with a heatresisting coating. The continuous surface shown is of glass cloth 8<SP>1</SP> carried in frames 8 of flexible, e.g. spring steel, which return to their normal shape after the shaping operation, but rigid surfaces could be used. The discontinuous surfaces 4 may be provided by a framework of parallel spaced rods arranged to give the required shape, the continuous surface then being a rigid refractory material.
