Title: Improvements in or relating to machines for moulding soil blocks
IPC: B30B11/10
Filed: 1953-05-22
Abstract: 749,377. Moulding soil blocks. WARNE, A. S. Aug. 20, 1954 [May 22, 1953], No. 14508/53. Class 87(2) A machine for moulding soil blocks comprises one or more tubular moulds 15, 16, 17; a compression ram 25; a plunger 22 coaxial with the ram 25 to form a depression in soil contained in the mould; a fixed table 18 which closes the bottom of a mould disposed in a first position coaxial with the ram and plunger 25, 22; an orifice 19 in the table 18 which registers with a mould disposed in a second position; a second ram 30 adapted to eject a moulded soil block from a mould in the second position through the orifice 19, and interconnected means for effecting depression of the rams and plunger. The interconnection is through a plate 23 to which a rod 21 from the plunger 22 is rigidly connected, through a crosshead 27, and a rod 31 from the ram 30 through a bracket 32. Two rods 26 from the ram 25 are slidable in the crosshead 27 and are surrounded by springs 29 positioned between the crosshead and collars 28 on the rods 26. An operating rod 24 is fixed to the plate 23 and is actuated by a connecting rod 39. A crank 37, driven from a motor 34 through reduction gearing, operates the lower end of the connecting rod and causes up and down motion of the plate 23 with the plunger 22 and ram 30. The crank 37 also operates a connecting rod 46 which reciprocates a crosshead 44 to which are fixed parallel rods 42, 43 slidably mounted in the frame 11, the rod 43 restraining torsional movement of the rod 42. A forked pawl unit 49 is pivoted at its inner end on the rod 42 and carries at its outer end a pin 50 which causes intermittent rotation of a ratchet wheel 48 secured to a vertical shaft 13 which drives a rotatable mould-carrying unit 12. When the rod 42 is making the ratchet driving stroke the plate 23 is raised, and when the unit 12 is stationary a mould, which has been filled at another position of the table, is under the plunger 22 and a mould containing a moulded soil block is under the ram 30. The plunger 22 descends and makes a depression in the soil, followed by the compression ram 25, and the ram 30 descends and ejects a moulded soil block through the' orifice 19, underneath being means which receive the moulded blocks and carry them outwards. The springs 29 retain the ram 25 on the soil block while the plunger 22 is rising, whereby the plunger is freed from the soil, pins on the rods 26 then engaging the crosshead 27 to raise the ram. To ensure that the mould unit 12 remains stationary while the rams and plunger are operating, a notched disc 59 on the shaft 13 is engaged by a spring- loaded bolt 61. When the rod 42 moves to cause the pawl 49 to operate the ratchet wheel 48 a projection 63 from the rod 43 moves to pivot a trip lever 65 which engages a pin 67 on the bolt 61, which is thus withdrawn to free the disc 59. The rotary mould unit may be interchangeable with other units.

Title: Improvements in Apparatus for Determining Directions and Speeds, for use on Aircraft.
Inventor: WIMPERIS HARRY EGERTON
Filed: 1918-09-14
Abstract: 131,757. Wimperis, H. E. Sept 11, 1918. Speed indicators operating by sighting terrestrial objects.-Relates to apparatus for use on aircraft, chiefly intended for determining the velocity of the wind. A graduated horizontal plate A is rotatably mounted on a frame having a lubber-mark M<1>, the central portion of the plate being marked with con- .centric circles Z and being adapted to have lines ruled on it. An arm C moving over the plate A is pivoted at D, the line joining D to the centre E of the plate A being parallel to, or coincident with, the longitudinal axis of the aircraft. The pivot D may be adjusted longitudinally by means of the screw R<3> so that the distance DE is proportional to the air-speed of the machine. To determine wind velocity, the plate A is rotated until the graduation corresponding to the compass bearing coincides with the mark M<1>; the arm C is set along the line of drift of the machine and a line ruled along it on the plate A. This operation is repeated on a. fresh course, and the line joining the point of intersection of the two lines thus obtained to the centre of the plate A represents the velocity of the wind to the same scale as the distance DE represents the air-speed of the machine. To indicate the point of intersection, a rotatable arm N is provided on which is an adjustable arrow M. If the ground speed is determinable, the wind velocity can be obtained from a single setting. To obtain the ground speed the time taken by an object on the ground to pass between two points S, S<1>. when observing through a sight on a vertical pillar above the pivot D, is measured. A graduated quadrant Q is provided on which the drift angle can be read, or, if the drift angle is otherwise obtainable, for example by directional wireless, the arm C can be set to the appropriate graduation on the quadrant Q and the apparatus can then be used disconnected from the machine.

Abstract: 355,285. Panoramic kinematography ; lens mounts. WILLIAMS, J. D., 82, Portland Place, London.-(Schwartz, G. ; 212, Avenue Raspail, Paris.) May 16, 1930, No. 15124. [Class 97 (i).] In apparatus of the type described in Specification 335,864, [Class 97 (i), Optical systems &c.], comprising a cylindrical lens or other anamorphotic system in conjunction with an image-forming system, for projecting panoramic images, the anamorphotic system is movable into and out of its operative position, and its movement controls a switch in the lamp circuit to increase the intensity of the light source during the time it is in use ; the movement may also adjust the position of the image-forming system, so as to produce a focused image in both positions of the anamorphotic system. As shown in Fig. 1, the anamorphotic system 30 may be turned about a pivot rod 19, into inoperative position, by a handle 33, a switch arm 45 being thereby turned over contacts 47 to insert resistance in the lamp circuit. In a modification, a switch block bridges one pair of contacts in operative position, and another in inoperative position, to complete circuits for different lamps. As shown in Fig. 3, the casing 31 of the system 30 also carries a cam arm 34 engaging a knob 36 on a rod 35 to vary the position of the ordinary projector lens system. The components 10, 11 of this system are carried by relatively slidable mounts 12, 13, the mount 13 being movable by a rack and pinion 15 to vary the separation of the components and effect focusing of the image. The mounts 12, 13 carries lugs 20, 21, respectively, engaging a tubular rod 22 carrying adjustable stops 27, 28 and housing the rod 35. The stops 27, 28 are adjusted, in a manner described in the Specification, so that, when, as shown, the system 30 is in use, a focused image is obtained when the lug 21 engages the stop 28, and, when the system is out of use, a focussed image is obtained when the lug 20 engages the stop 27. Springs 37, 38, abutting respectively against the knob 36 and the frame, ensure such engagements in the two positions of the system 30.

The reeds 4, Fig. 6, are fed forwards, singly, from the bottom of a magazine 3 by lugs 6 on a chain 5, and pass between rapidly-rotated brushes 33, 34 mounted on adjustable arms 35, 36. The reeds are thus cleaned, and they may also be polished by rapidly-rotated brushes 54, 55, which remove temple marks &c. and restore curved contours to the reed-dents. The reeds are delivered by chain-driven rollers, covered with friction material &c. to a special yieldingly-supported tray, which is inclined when empty. The chain 5 is driven slowly by a sprocket-wheel, either at a constant speed, or intermittingly, through gearing, which may include a friction-clutch, from a shaft, driven by an electricmotor &c. The rapidly-rotating brushes 33, 34 &ct as fans and suck air into the casing 52 of the brushes, lint &c. from the reeds being discharged through a suitable passage. The reed edges are protected by yieldingly-held upper shields 64, Figs. 6 and 9, and lower shields 65, the shields being mounted upon side-members 66, 67, adjusted by means of threaded rods 72, to accommodate reeds of various heights. Similar threaded rods connect the side members of the magazine 3, and they may simultaneously be adjusted by a chain passing over sprocket-wheels 78. Electrical and mechanical stop-motions are described for stopping the machine when the last reed in the magazine has passed beyond the cleaning and polishing brushes. The machine may be re-started manually, or automatically when the magazine is refilled. Cleaning or polishing material may be applied to the cleaning or polishing brushes, or both, and special means for intermittingly moving sticks of cleaning or abrading material into contact with the brushes 54, 55 are described. Oil &c. may be applied to the reeds, special means for delivering oil from a tank to two brushes acting on the reeds being described. A reciprocating as well as a rotary movement may be given to the cleaning or polishing brushes, or both, and special adjustable spring-controlled means, including parallel-motion linkwork, are described for reciprocating the brushes between the members 66, 67, the extent of this reciprocation being adjusted automatically correspondingly with the adjustment of the members 66, 67 though it may be adjusted independently also. Special means for yieldingly varying the. pressure of the brushes on the reed are used in this modification, and also devices for rotating the sticks of abrading-material &c.
