Title: Improved machine for moulding hollow blocks
IPC: B28B1/08
Filed: 1947-07-02
Abstract: 640,519. Shaking-machines for moulding concrete blocks. SAND, S. July 2, 1947, No. 17463. Convention date, July 3, 1946. [Class 87 (ii)] A machine for moulding hollow concrete blocks comprises a stand 1, a mould box which may be turned over sideways through 180 degrees, and withdrawable cores projecting upwards into the box, and is characterised by vibrating means which act upon a frame which is vertically movable in the stand, in which frame the mould box rests and to which it is hinged by one of its edges. The frame may hold two mould boxes 7, 8 which are hinged at 9, 10 to two opposite sides of it, two sets of cores being then provided. The vibrating means comprise a horizontal shaft 14 with a crank handle 15 at one end on which shaft two wheels 16, 17 are secured having ratchet-shaped teeth adapted to co-operate with studs 18, 19 fixed to opposite sides of the frame. The studs, which do not reach the bottoms of the notches, can be adjusted vertically. The cores 20 for the mould box 8 are fixed to a plate 22 mounted on vertical rods 24 to which is secured a bar 32 pressed upwards by springs 30, and the core plate 22 can be tightened against the bottom of the frame 2 by a wedge-shaped lock-plate 40 which can be pushed under the edge of the plate by a slider 37 sliding on a rail parallel to the shaft 14. The cores for the mould box 7 are similarly mounted. To enable the cores to be withdrawn the core plates have notches whereby they can be brought out of engagement with the lock-plate, and fixed to the bar 32 is a rope 33 whose lower end passes round a wheel 34 which may be turned by a handle to coil up the rope on it. An additional vertical guide for the frame 2 is provided by a socket 6 which receives a pin 5 at the bottom of a fork whose upper ends 4 are attached to the frame 2. After the material has been vibrated in the mould it is smoothed off on top by a board 13 which is then fixed over the top of the mould box. The cores are withdrawn and the mould box turned over on to a platform 11. The wall 12 of the mould box is detached from the rest of the box and fixed to the stand in the position shown dotted and the rest of the box is swung back, leaving the moulded article on the platform. The board 13 with the moulded block is then removed and the wall 12 swung back and fastened to the rest of the box. When two mould boxes are used another platform corresponding to the platform 11 is placed on the opposite side of the stand. To make the fullest use of labour the machine is arranged so that all handles are on two opposite sides only of the stand.

Title: Means for automatically adjusting the lubber line of a compass for use on aircraft
IPC: G01C17/00
Filed: 1919-07-12
Abstract: 157,488. Houghton, A. B. July 12, 1919. Aeronautical compasses. -Adjustment of the lubber line of an aeroplane compass to compensate for lateral drift is stated to be effected by two co-operating vanes fixed on the machine. In the construction shown, in which the line ZZ represents the base of the fuselage, the balanced wind vane 23 pivoted about the shaft 20, and the smaller balanced vane 15 pivoted about the vertical shaft 12, are connected by bevel-gearing 18, 19. The shaft 12 is connected by a slotted wheel 10 to the crank-pin 8, which rotates the compass bowl 5. The relative sizes of the vanes and the bevel-wheels are determined for each machine, and it is stated that a side wind displaces the vanes and thus adjusts the lubber line of the compass.

Filed: 1953-06-24
Abstract: 745,237. Electric measuring systems. METROPOLITAN - VICKERS ELECTRICAL CO.. Ltd. May 31, 1954 [June 24, 1953], No. 17521/53. Class 40(1) [Also in Group XI] The temperature rise in an electrical motor is determined by measuring the temperature rise in a stationary thermal replica comprising a copper rod or cylinder 1 representing the armature or rotor, surrounded by an iron cylinder 2 representing the iron circuit of the machine, the copper cylinder 1 being fed with a current proporportional to the armature current, and the iron cylinder 2 being fed with a normally constant heat to represent the iron losses. The cylinders are each covered with thermal insulating material 3, 5. The copper cylinder 1 has metallic ends 4 which also serve as the terminals for the heating current. A temperature-sensitive resistor 7 is wound on the copper cylinder 1 and is connected in a bridge circuit for indicating the temperature. The device is located in the air-flow of the machine to be subjected to the same cooling conditions.

Title: Improvements in coin counting machines
IPC: G07D9/00
Filed: 1932-06-21
Abstract: 382,254. Coin-counting apparatus. STANDARD-JOHNSON CO., Inc., 371, Pacific Street, Brooklyn, New York, U.S.A. June 21, 1932, No. 17565. Convention date, Dec. 16, 1931. [Class 106 (i).] In a machine wherein the coins are fed to a star wheel 11 by means of a rotating table surrounded by a flanged rim 6, the rim and an ejecting arm 47 are simultaneously adjusted for thickness and diameter of coin. The coins are prevented from passing out from under the flange 7 by a further flange 8 interrupted at the escape point where the arm 47 diverts them to a constantly driven wheel 10 which passes them between the star wheel and an adjustable guide 37. The rim 6 is spring- supported and is positioned by three jack screws 12 threaded in the baseplate 1 and geared together by pinions 13 and a gear wheel 14, and by turning one of the screws by means of a knurled head 17 the height of the rim and its flange with respect to the table is adjusted. On the gear wheel is a cam 26 and by this adjustment the cam acts upon an arm 24 to vary the position of the coin-diverting arm 47 according to the diameter of the coins. The position of the guide 37 is adjustable by a knob 43.

Abstract: 1,135,174. Photographic apparatus. INTERNATIONAL POLAROID CORP. April 21, 1966 [April 21, 1965], No.17572/66. Heading G2A. In a self processing camera the photo-sensitive sheet is processed by a liquid spread between it and an image receiving sheet when the sheets are passed between rollers 80, 82 in a housing 60 to an exit aperture 84 normally closed by spring leaf 100. A guide member 160 located adjacent the rollers supports at least the lateral margins of the sheets, and a pair of elongated members 170 between the member 160 and the rollers 80, 82 co-operate with parts 162 of the member 160 for compressively resiliently engaging the edges of the sheets to prevent undesired movement of the sheets through the rollers and escape of liquid from the sheets when they are advanced between the rollers. The member 160 is mounted on a support plate 136 which is slidable in channels 144, 146 in the sides of the housing 60. The plate 136 carries a torsion spring 128 which urges the roller 80 into the sheet engaging position. The rollers have stud shafts 116, 118 which engage in recesses 122, 124 in the housing side walls, so that when the plate 136 (and hence the spring 128 and members 160, 172) is moved along the channels 144, 146 to the left hand end as shown, the roller 80 is free to move down the recesses 124, and thus separate the rollers 80, 82 for cleaning purposes.

Title: Method and apparatus for embedding stators of electrical machnes  in a hardenable plastics material
IPC: H02K15/12

Abstract: 1384468 Embedding stators in plastics material POLYMOTOR ITALIANA SpA and GAMBA & FIORITO COSTRUZIONI MECCANICHE DI PRECISIONE SpA 17 April 1972 [16 April 1971] 17728/72 Heading B5A  A stator 20 of an electrical machine is embedded in a curable plastics material by placing it in a centrifugal mould 7, 8, rotating the mould about the longitudinal axis of the stator, feeding liquid plastics material from a reservoir 13 into the mould via a valve 15 until the desired embedding level is reached and continuing mould rotation until the material is substantially cured. The two parts of the mould are joined by bolts 9 and attached by bolts 6 to the head 5 of a rotary shaft 3. The diameter of a port 208 in the mould part 8 determines the material level in the mould, and the surplus material flows into a pan 12 from a spout 11 in a splash guard 10. An electrical lead 120 from the stator windings is received in an axial bore in the shaft. In one embodiment, the tops of the stator slots are not filled with plastics in a first stage by using a mould half 8 with a port 208 of appropriate diameter; in a second stage, the said mould half is replaced by one having- a port of smaller diameter and using a plastics material charged with a magnetic substance, to thereby provide magnetic strips in the tops of the slots. In a further step an inner corrosion resistant liner is provided in the stator. By a suitable shaping of the mould a flange may be formed integrally with the stator.
