Title: Method of, and apparatus for, laying bricks
IPC: E04G21/20
Filed: 1955-09-07
Abstract: 783,224. Brick-laying apparatus. LUDER, F. K. Sept. 7, 1955 [Sept. 8, 1954], No. 25688/55. Class 20(4) A layer of mortar is applied to the top of a brick, prior to laying it in the wall, by means which ensure that the combined height of the brick and the mortar is constant. A layer of mortar is also applied, by the said means, to an end surface of the brick, so that the combined breadth of the brick and mortar is constant. As shown, bricks 6 are laid in pairs on a table 3 reciprocable beneath a mortar hopper 7 which is adjustable vertically, to determine the thickness of the mortar layer, by screws 14. The table 3 carries an obturating plate 11 which closes the bottom of the hopper when the table is pulled forward for the receiving of, or removal of, bricks. A flap 4, one for each brick 6, is pivoted to the table and extends downwardly to such an extent that it contacts, during the return motion of the table, with an adjustable stop 4c. When the bricks have been laid on the table, the latter is pushed inwardly to position the bricks beneath the hopper, the plate 11 being moved away from the hopper as the table advances. The mortar is thus applied to the top of the bricks, and some falls between the end faces of the bricks and the flaps 4. The table is then returned to its initial position, the edge of the hopper striking off the mortar to the predetermined thickness. The mortar between the flap 4 and the brick is pressed into a recess in the brick by the flap swinging clockwise as its lower part contacts with the stop 4c. Springs 12, carried by the hopper, produce grooves in the mortar applied to the top face. A tiltable handle 5 is then swung to tilt the bricks to facilitate removal by hand. The table may be stationary and the hopper reciprocated. The apparatus is mounted on a wheeled chassis 1.

Title: Dewatering of slurries
IPC: C02F11/123
Filed: 1974-06-12
Abstract: 1479318 Apparatus for dewatering slurry ALB KLEIN KG 12 June 1974 [13 June 1973] 26024/74 Heading BID  Slurry is dewatered by squeezing between two endless sieve belts 4. 5 which pass firstly between a straight set of rollers 9 and then in an S-like path round rotating drums 1. 2 against which the belts are pressed by rollers 40. Fig. 1 also shows a preliminary gravity filtering on the upper run of belt 4, from which partly dewatered slurry falls at 8 on to belt 5. Rollers 9 are staggered to curve the belts to some extent (not shown) and mounted on spring-loaded plates P. In an alternative construction (Fig. 3 not shown) rollers 9 are mounted on two endless conveyors whose adjacent runs are backed by plates which are spring-urged together to press the belts. The rollers on the two conveyors may differ in size and spacing, and the conveyors may be driven at slightly different speeds. The conveyors may move the belts forward, or the belts may be moved by rotating one or both drums 1, 2 and may in turn move the conveyors. Drums 1, 2 have peripheral walls of perforated or grooved steel or built up of axially oriented tubes (Fig. 2 not shown), which may be perforated and serve to drain filtrate from the drum interiors. Drums may be driven at slightly different speeds. Rollers 40 are pivotally mounted relative to the drumsupporting frames on levers which carry adjustable pins (47), and pins (47) are engaged by a circumferential cable on each drum. The cables are tightened by handwheels or winches to urge the rollers 40 on to the drums, and the individual forces applied by the rollers may be adjusted by adjusting pins (47) to vary the leverage. The belts 4, 5 separate to discharge filter cake at 53, and their return runs via washing stations 56 may be supported by the outer parts of some rollers 40. The flexing of belts 4, 5 caused by changes in direction and differential speeds of supporting members breaks up the filter cake between the belts to expel water pockets. In Fig. 4 (not shown) the initial pressing silage is arranged beneath the drums, and there is no gravity filtering. The apparatus may include a strainer (unspecified) which removes some water from the slurry before the slurry reaches the belts. The belts could pass round more than two drums. Rollers 9 could be vibrated.

Abstract: 878,405. Gauging alignment of parts of machines. WARNER & SWASEY CO. July 29. 1959 [Aug. 7, 1958], No. 26055/59. Class 106 (2) [Also in Group XX] Apparatus for gauging the alignment of an object 1 comprises at least one pair of probes 10, 12, which contact the opposite sides of the workpiece, members 50, 51 moving in dependence on the movement of the probes 10, 12, and an indicator 54 moving in accordance with the movement of the members 50, 51 to indicate the mid-point b 1  of the points of contact of the probes with the workpiece 1. In the embodiment shown four probes 10-13 are used and an indication is given of the angular position of the line joining the mid-points of their points of contact. The probes 10-13 are retractably mounted in holders 6 on carriages 3, 4. The carriages 3, 4 are driven forward by motors 116, 115 and rack bars 50-53 connected to driving carriages 20, 21 move in accordance with the carriages 3, 4, but through a much greater distance. When each probe touches the workpiece 1, a corresponding solenoid 22 is energized thus releasing a pawl 26 from a notch 30 and allowing a brake to be applied to the corresponding rack bar to hold it in the position reached. When all four probes have contacted the workpiece, the positions of pinions 54, 55, each meshing with two of the rack bars, indicate the twist of the workpiece relative to a fixed line. The actual twist measured is the angle between b 1 , b 2  and the corresponding line on a master workpiece, where b 1 , b 2  are the midpoints of the lines joining the points of contact of the pairs of probes. If this angle is within the required tolerance, a stylus 57 carried by the pinion 54 contacts an electrically conducting region 60 on a tolerance bar 59 carried by the pinion 55, and a lamp 82 lights up. The pinions 54, 55 are carried on trolleys running on guide rails and the trolleys also carry the stylus 57 and tolerance bar 59. By a simple re-arrangement of the electrical connections, the angular displacement of the chord connecting the points of contact of probes 10, 11 can be indicated and by reversing one of each pair of racks the thickness at the points of contact can be investigated. Specification 832,553 is referred to.

Abstract: 794,897. Gas turbine plant. ROLLS-ROYCE, Ltd. Aug. 19, 1955 [Sept. 8, 1954], No. 26071/54. Class 110 (3). [Also in Group XXIX] A gas-turbine engine having inlet guide vanes, or stator blades, or bleed valves, which are required to be adjusted in accordance with engine rotational speed or the square of the rotational speed and in which the adjustment is effected by a ram the operation . of which is controlled by an hydraulically produced force bearing a given relationship to the engine rotational speed, is provided with means producing an hydraulic pressure which exceeds a given low pressure by an amount related in a predetermined manner to the rotational speed, a conduit having a pair of restrictors arranged in series leading to a region at the low pressure, and the pressure drop across one only of the restrictors supplying the force for controlling the ram. An engine-driven pump 10 is connected to a suction pipe 15 and to a delivery pipe 16 connected to fuel injectors 16a. The ram, which may adjust the inlet guide vanes of an axial flow compressor, comprises a differential piston 18 in a cylinder 17 having a chamber 20 connected through a duct 21 to the delivery pipe 16, and a chamber 22 connected to the duct 21 through a restrictor 23. The chamber 22 also has a bleed passage 24 controlled by a valve 25. A duct 33 leads from the delivery pipe 16 to a pressure-reducing valve 34, and a duct 35 leads from the valve 34 to the suction pipe 15 and contains restrictors 32, 36. An hydromechanical governor 49 maintains the pressure in a chamber 39 of the valve 34 equal to an amount proportional to the square of the engine speed plus the pressure in the suction pipe, and the pressure in a chamber 38 of the valve is maintained at this value, so that the total pressure drop across both restrictors 36, 32, and hence the pressure drop across restrictor 32, is proportional to the square of the engine speed. This pressure drop is applied across a diaphragm 31 controlling the valve 25, and springs 28, 30 ensure that for each value of the pressure drop the piston 18 takes up a corresponding position. The area of the restrictor 32 is varied by a temperature-responsive capsule 42 subject to the compressor air inlet temperature or atmospheric temperature.
