Title: Improvements in and connected with machines for washing sand, gravel, and other likematerials
IPC: B03B5/56
Filed: 1933-03-11
Abstract: 414,809. Washing granular materials. PEEBLES, J., Waterworks Cottage, Dalrymple, and GLENFIELD & KENNEDY, Ltd., Kilmarnock, both in Ayrshire. March 11, 1933, No. 7429. [Class 82 (ii).] Material such as sand and gravel to be washed is fed into a rotating perforated drum partly submerged in a water trough, the larger particles being discharged from the washing drum into a rotating perforated rinsing drum, coaxial with the washing drum, where they are sprayed with water. The material is fed by a shoot 1 to a perforated washing drum 2 to the rear end of which is attached a smaller drum 4 provided with a rinsing spray pipe 5. The drum 2 is mounted on bearing rollers 18 and the drums are rotated by means of worm gearing 21, 23. The larger particles, e.g. gravel, are passed along the drum 2 by vanes 2<1> and pass at the rear end of the drum into one or more openended boxes 3<a>, 3<c>, attached to the drum, by which they are raised, drained, and deflected into the rinsing drum 4 where they are sprayed and discharged either by making the drum 4 divergent or, as shown, by providing vanes 41. The finer particles, e.g. sand, pass through the perforations of the drum 2 into a trough 10 along which they are conveyed by vanes 24 on the outside of the drum. The sand reaching the end of the trough 10 falls into a recess 12 and is forced by a jet of water from a nozzle 14 up a tubular passage 13. The sand banks up at 15 and is discharged by wipers 16 attached to the outside of the drum 4. The water from the rinsing spray pipe 5 and the jet nozzle 14 mixes in the space 7 and passes back along the drum 2 and the trough 10 to an overflow 11.

Title: Improvements relating to the protection of motor vehicles, aircraft and the like in case of accident and against theft
IPC: H01H35/14
Filed: 1932-03-17
Abstract: 385,487. Inertia switches. BATE, B. DIXON-, Bridge Works, Tarvin Road, Chester. March 17, 1932, No. 7951. [Class 38(v).] In order to prevent fire in case of accident to vehicles and aircraft and also to guard against theft a mass or weight z is provided so associated with toggle-lever mechanism u, t that when the vehicle meets with an obstruction the momentum of the weight causes the toggle to collapse and actuate through a mechanical linkage means whereby any or all of the following are caused : (1) the cutting-off of the engine fuel supply, (2) the isolation of the electric accumulator from the distribution system, (3) the earthing of the magneto, (4) the isolation of the ignition coil from the accumulator, and (5) the earthing of the dynamo positive lead. The toggle linkage may also be actuated in the case of the overturning of the vehicle or of impact in a direction at rightangles to the direction of motion. In the construction shown the apparatus is in the normal running position, with the toggle link t resting against an adjustable stop w. When the vehicle meets an obstruction the weight z moves forwards towards the front 4 of the apparatus and allows a spring r to rock a lever c and cause the toggle to collapse and rock a lever 9, 10 by means of a cam 7. The movements of the levers cause (1) the fuel valve (not shown) to close by means of a wire or cable p, (2) the accumulator main lead a to be broken at contacts d, (3) the magneto wire e and a dynamo lead f to be connected by contact 11 to an earth wire g, and (4) the. opening of the coil ignition circuit wire at the contacts m. The weight z is adjustable on the link u so that the sensitivity of the apparatus may be controlled. The toggle may be reset by means of a handle and a cable x, and this handle may be used to operate the toggle so as to put-the vehicle out of action, a lock and key being provided for the handle to prevent unauthorized use of the vehicle. Lost motion connections are provided between the toggle linkage and the parts controlled thereby, so that the valve and switches are not operated until the toggle has passed the dead centre and thus the resistance which the weight z has to overcome is constant. A second weight 13 can oscillate on a pivot 14 at right-angles to the pivot of the link u and carries cams 17 acting on a spring-controlled lever 18 adapted to engage the toggle u, t, so that if the vehicle overturns or receives a side impact the. weight rotates and actuates the lever to collapse the toggle and thereby bring the safety apparatus into action.

The body may be rotated upon the turntable by a pinion 22 engaging a rack 21 on the member 8 and operated by the shaft 23, worm gear 24, 25, and hand-wheel 29. The rails 11 may have inclined ends down which rollers 14 on the body may run to facilitate the tipping of the body about the pivot d. Inter-engaging members 30, 31 on the longitudinals 2 and rails 11 prevent the rails 11 from rising. Slots b are provided in the rails 11, 12 for the pintles of the rollers 13. and a slot f in the rail 11 permits the travel of the shaft 17. Means for opening the end door of the body automatically when the body is tilted may be provided.

Filed: 1928-03-17
Abstract: 287,457. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). March 19, 1927, [Convention date]. Regulating and controlling.-To reduce the noload running losses of a compressor a, its suction and discharge pipes b, d are connected by pipes h, m with valves g, l, to a container which can be partly evacuated by the compressor. When the compressor is loaded the valve c is open; air is drawn from the pipe b and forced through the pipe d into the system. During this time the valves i, g, l, remain closed. When the load is taken off, the valve c is closed and the valves i, are opened. The compressor then draws air from the container f through the valve h and passes it into the atmosphere through the pipe k and valve i. When a sufficiently low pressure has been reached in the container f the valve i is closed and the valve l is opened so that both suction and discharge pipes b, d are connected to the low pressure container. The valves may be operated automatically in proper sequence.
