Filed: 1919-02-03
Abstract: 141,445. Rees, E. S. G. Feb. 3, 1919. Stopping way; steering and balancing.-In aircraft provided with a longitudinal open-ended duct surrounding or immediately in the rear of the airscrew, the duct is made with a rearwardly expanding portion, and is provided with a movable pallet or pair of pallets adapted to close or partly close the rear end for manoeuvring purposes. The pallets may be used as ailerons or brakes. The trunk a, Fig. 1, flares toward points d, at which position pallets c are pivoted, and about which they are adapted to be independently or simultaneously moved. The shaped outer surface e is of approximately stream-line form. As applied to a tractor biplane, the oval-sectioned duct encloses the fuselage f. Fig. 5, the effective cross-sectional area increasing from front to rear. With pushertype machines, the duct is completely behind the wings, and an additional stream-line member may be placed therein to provide the necessary change in sectional area. In multiple-engined machines, the ducts surround the stream-lined enginenacelles. In a two-engine machine, Fig. 14, the ducts carry biplane members h between them, and braced monoplane members i extend outwardly.

Title: Improvements in or relating to methods of treating calcium carbonate powders
IPC: C09C1/02
Filed: 1956-01-27
Abstract: Calcium carbonate powders are coated with a quaternary ammonium compound which consists of a salt of a halogen acid, and either the nitrogen atom of the quaternary ammonium radical is linked to a benzyl radical and organic radicals of an aliphatic or aromatic type at least one of which contains 8 or less carbon atoms, or the said nitrogen atom forms part of an aromatic nucleus (e.g. pyridinium quinolinium) or analogous heterocyclic nuclei and is linked to one other aliphatic or aromatic radical.  The quaternary ammonium compound is applied by a dry process which does not involve the formation of a suspension of the calcium carbonate in a liquid medium.  According to one example, calcium carbonate was dehydrated to a moisture content of less than 0.1 per cent and then finely ground to an average particle diameter of 1 to 2 microns.  A 50 per cent solution of dimethyl laurylbenzyl ammonium chloride was sprayed on to the ground calcium carbonate to provide 0.4 per cent by weight thereof.  Alternatively the mixture of chalk and quaternary ammonium compound may be introduced into a grinder where the heat of the grinding operation is sufficient to render the quaternary ammonium pcomound plastic.

Title: Coin dispensing machines
IPC: G07D1/00
Filed: 1974-01-22
Abstract: 1441215 Coin chutes ARDAC Inc 22 Jan 1974 [26 Fob 1973] 02864/74 Headings G4V and G4X A chute for use in a coin dispensing machine is as shown in Fig. 3 and has arms 42, 44. There may be more than two arms and they need not be at right angles to each other. The arms receive coins alternately with coins received by and stored in the chute supporting a subsequently received coin on the edge thereof with the two coins abutting on their edges in a non-aligned manner. Dispensing means from the chute may be by solenoids and plungers. For dispensing an even number of coins the solenoids and plungers would both be associated with the same chute. For dispensing odd numbers the solenoids and plungers would be associated with different chutes. Alternatively a rotatable gate so controlled by a stepping switch or a logic network may be used. Fig. 6 shows a preferred method and apparatus for feeding coins to the chute. A flipper 62 has a centre of gravity above pivot 68 so that coins dropping through funnel 60 are alternately directed to channels 64 and 66, and thence arms 42, 44. Alternatively, a rotatable gate could be used.

Title: Method of and apparatus for winding armature cores
Inventor: FARMER CECIL
IPC: H02K15/09
Filed: 1959-01-27
Abstract: 862,483. Coil-making apparatus. GOLDMAN, A. D., and GOLDMAN, Y. Jan. 27, 1959, No. 2911/59. Class 35. An apparatus for winding an armature core for an electric generator or motor uses several precut wire units, each sufficiently long to wind two coils on the core. Core 25 is mounted with its shaft 57 held in a chuck 54 on top of rigid post 21. Mounted in sliding relation with the post are two sleeves 36, 39 joined by a rack bar 40 which co-operates with a gear pinion 41 turned by handles 46 and braked by brake band 48. Upper sleeve 36 carries rods 38 attached at their upper ends to annular member 32 which rotatably supports a table assembly 22 which in turn carries near its periphery rotatable spools 60 whose angular spacing is equal to that of the armature grooves. The table has an annular central guide 66 (Fig. 2) provided with slots 70 corresponding to the armature grooves. On the upper end of armature shaft 57 is loosely mounted annulus 72 carrying pins 73 equal to half the number of armature grooves. The precut wire units (Fig. 11) each comprise two lengths of insulated wire 10, 11 laid side by side and bent into a U-shape, each arm 12, 12<SP>1</SP> being sufficiently long to make one coil. The insulation is removed at bight 13 and ends 15. Bight 13 is anchored round a pin 73 and arms 12, 12<SP>1</SP> are laid in adjacent slots 70 in guide member 66, passed round adjacent spools 60 and laid in the space between the spools and the edge of the table, being retained by pins 65. Retaining annulus 82 prevents the wire moving out of slots 70. A wire unit is similarly arranged on each pin 73. To wind the armature table 22 is first lowered to a position below the core (Fig. 8, not shown) so that a pair of wire portions 10, 11 is inserted in each groove. The table is then indexed through 180 degrees and raised so that each pair is inserted into a groove diametrically opposite to its initial one. On now indexing through 180 degrees in the opposite direction the wire portions are aligned with their original grooves and the procedure of lowering, indexing, raising and re-indexing is repeated until winding is complete, when bights 13 are cut. In an alternative form of wire unit arm portions 12, 12<SP>1</SP> are each wound into separate helical coil which is positioned on spool 60 from which it unwinds during winding of the core.

Title: Improvements in devices for cooking waffles and such like products
IPC: A21B5/02
Filed: 1933-01-30
Abstract: 401,917. Making waffles and the like. RATTI, J., 115, Rue Edouard Vaillant, Levallois-Perret, Seine, France..Jan. 30, 1933, No. 2920. Convention date, Jan. 30. 1932. [Class 28 (i).] In a machine for cooking waffles and the like, the pairs of cooking irons are hinged and locked together by means incorporating springs which permit slight separation of the irons for the escape of steam, and a slight separation is, in addition, positively effected by the usual roller 9 of the upper iron passing over an undulating cam. The space between the irons is normally closed by guard elements 45 secured to one of the irons. The hinge 3 is mounted on a sliding spring-returned rod 42, and the rotary lock 7 is slidable in a casing containing a spring 6 which tends to move the lock downwardly. It is desirable that, immediately after charging the irons with batter and closing them, the irons should be opened slightly for venting the steam. It is therefore necessary to raise the lock positively in order that it may be turned into the locked position. This is effected by a depending portion 15 of the lock engaging a recess in the top of a block 14 which is slid, by the onward movement of the portion 15 with the irons, between guides 16, 17, the upper faces of which are formed as cams. The cam action first raises the lock to permit it to be turned by the engagement of the star wheel 26 with a stationary stop 24, and then lowers the block 14 away from the portion 15 to permit the springs 19 to return the block to engage the locking-means of the next pair of irons. A resilient device 28 prevents the top irons from being raised too far and fouling the lock 7 as it is rotated. A modified form of lockraising block is used for machines where the baking-irons travel vertically at the locking- position. The undulating cam for positively raising the upper iron is secured adjustably at one side of a stationary rail, the adjustment and fixing being effected by eccentric bolts and clamping-screws.

Abstract: 765,301. Steering ships. AUTOMOBILFIRMA RAGNAR JANSON AKTIEBOLAG. Feb. 1, 1955, No. 2938/55. Class 114. [Also in Group XXIX] A ship's steering wheel and rudder are connected by a telemotor system comprising two transmitter units mounted one on each side of the steering wheel shaft and two receiver units mounted one on each side of the rudder. Each transmitter unit comprises a piston and cylinder mounted on a reservoir 17 and each piston has a longitudinal bore therein engaged by a plunger fixed to the reservoir, the plunger pumping liquid into the system to make up any loss and releasing any air that may collect in the system. The piston 7, moved in the cylinder 5 by a gear wheel 8 on the steering wheel shaft 9, has a bore 15 engaged by the plunger 16 which forces liquid through a valve 20 when the piston rises. When the piston is in its highest position, a projection 28 opens the valve 20 and allows any air in the system to pass into a bore 23. The air escapes through a valve 26 when the piston 7 next moves upwards. Ports 22, 24 connect the bore 15 with the reservoir.

Abstract: 987,801. Abrading. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 21, 1964 [Jan. 23, 1963], No. 2945/63. Heading B3D. A method of machining hard materials comprises ultrasonically activating an abrasive impregnated probe, moving a workpiece relative to the probe, and supplying a coolant fluid between the probe and workpiece. The probe 4 is mounted in the holder 5 of an ultrasonic generator 1 vertically movable in a guide head 2 under the control of a counter balance 6, which is connected by a cable 7 to the generator, and an hydraulic unit 31 which provides for a slow advance and rapid withdrawal of the probe relative to a workpiece held in a chuck 10. The chuck is of the 4-jaw type and is mounted for rotation on a machine table 11, the chuck being secured to a shaft 17 which is mounted in bearings 18 in a support block 19 and connected by a belt-drive 13 to an electric motor 12. The support block 19 is disposed within a coolant drain tank 20 and coolant is prevented from reaching the bearing by a seal 22 and shroud member 16. The probe may be solid and be impregnated with abrasive, for example, diamond dust, and have flutes or flats formed on its peripheral surface for the passage of coolant. Alternatively, the probe may be formed of a hollow shank 24 having a diamond impregnated tip portion 25. A pair of passages 29 connect the end face 26 of the tip portion to the shank bore 30, which is connected to a supply of coolant, and the peripheral face of the tip portion is formed with grooves parallel to the axis of the shank for flushing away waste particles. For trepanning, the probe may be hollow or a solid probe used with a workpiece rotated in an offset manner. The machine may also be used to form annular grooves and threads by rotating and traversing the workpiece at rightangles to a suitably shaped probe. The material of the workpiece may be hard ceramic such as sintered uranium dioxide.
