Title: Machine for washing, dyeing or the like treatment
IPC: D06B3/02
Filed: 1929-09-26
Abstract: 334,730. Dassonville, M. March 9, 1929, [Convention date]. Dipping-apparatus. - A machine for washing. dyeing, &c. in which a set of tanks are arranged circularly around a central vertical axis, the material to be treated being suspended from a frame carried on the vertical axis and which can be rotated thereon and given a vertical ascending and descending motion to immerse the material successively in the tanks, has means provided for giving the frame a vertical reciprocating motion of small amplitude for shaking the material in the tanks without removing it therefrom. The suspending frame is carried by a tubular shaft 12 resting on a collar and ball race 16 attached to two connecting rods 17, 18. These rods are connected to two beams 19, 20 pivoted on a shaft 21 and moved respectively by frames 26, 35, also pivoted to shaft 21, the cross-bars of which 24, 34 may engage in hooks 25, 33. The weight of the suspending frame is greater than the counterweight 22, 23 so that it always tends to move downwardly. To raise the suspending frame a rack and pinion 27, 32 is driven, preferably by an independent prime mover, the bar 24 engaging the hook 25 and forcing it downwardly. In order that the shaking motion may be imparted to the material in the tanks, the rack 27 is raised so that the bar 24 leaves the hook 25 and motion is then imparted to the frame 35 and beam 20 by an independently-driven crank and connecting rod 37, 36, the frame 26, rack and pinion 27, 32 remaining stationary. The rotary motion of the suspending frame is obtained by a separate prime mover through shafts. bevels, &c. A space is preferably provided between a pair of the tanks to allow for loading and unloading the material.

Abstract: 890,900. Radio receiver apparatus. MURPHY RADIO Ltd. Sept. 16, 1960 [Aug. 27, 1959], No. 29360/59. Class 40(5). In a television receiver for 405 line and 625 line or similar systems, the I.F. vision amplifier has high attenuation at the sound I.F. of the 405 line transmission and substantially uniform amplification over the range of four or more m/cs., the receiver having coils selected by a channel and line standard selector which places the vision I.F. of the 405 line transmission approximately 3.5 mc/s. below the upper region of high attenuation and the vision I.F. of the 625 line on or near the upper edge of the passband. The I.F. response curves shown in Figs. 3 and 4 have a 4 mc/s. passband and high attenuation points at 38.15 and 33.15 mc/s. corresponding to the sound and adjacent-channel sound carriers of the 405 line system, the vision carrier of the 405 line system being located at 34.65 mc/s. as shown in Fig. 3. The absence of the usual sloping response associated with  the vestigal sideband transmission is compensated elsewhere in the receiver. For 625 line transmissions the I.F. vision carrier of 37.65 mc/s. is located as shown in Fig. 4. The I.F. sound carrier is located at 31.65 mc/s. where there is sufficient response to permit the osc. of the "inter carrier" sound system, Fig. 5 (not shown). Alternatively the sound signals for both 405 and 625 systems may be extracted immediately after the frequency changer (Fig. 6, not shown).

Filed: 1938-10-12
Abstract: 504,106. Clocks; synchronising two pendulums. SPROXTON,. K. Oct. 12, 1938, No. 29540. [Class 139] In order automatically to synchronize two pendulums a, b swinging in intersecting planes, one pendulum b has a member e which is displaceable relatively to the pendulum b to alter the effective length of the latter, when brought into contact with the other pendulum a, the two pendulums being suspended from adjacent points in or near the line of intersection of the planes. The main pendulum a swings in a plane at right-angles to the satellite pendulum b which swings in the plane of the paper. Threaded on an upright rod d of pendulum b is a nut e with spokes f; the pendulum a has two depending rods c, c<1>. When the pendulums are in synchronism, Fig. 1, they cross one another's path without touching. If pendulum b is fast, Fig. 2, rod c<1> meets a spoke f and causes nut e to move downwards to slow up the pendulum b. This occurs as b is moving to the right and a towards the observer. If b is slow, rod c causes nut e to rise. In a modification, pendulum b has two upright threaded members, each with a weight having spokes, and pendulum a has, between the said two members, a single coacting rod.

Abstract: 364,630. Heavy current switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Blume, L. F. ; 15, Arlington Street, Pittsfield, Massachusetts, U.S.A.) Oct. 3, 1930, No. 29655. Convention date, Oct. 3, 1929. [Class 38 (v).l Regulating - switches ; sparking, preventing, devices. -Switches of the kind in which a main connector is movable from one to another of a series of terminals, and an arcing connector moves between and engages the same terminals during the motion of the main connector, have connectors interconnected in such a way as to move relatively to one another and along dissimilar paths of movement when moving from one terminal to the next. As applied to a switch of the character described in connection with Figs. 5 and 6 of Specification 225,591, [Class 38 (v), Electric switches &c.]. a plurality of terminals 10 .. 15 are supported between endplates 16, 17 and adjacent pairs are adapted to be bridged by contacts 20, 21 on a connector 19 freely rotatable on an offset part of a shaft 18. The connector 19 has a rigid arm 23 carrying a roller 24 normally in a recess 25 in the plate 16 but movable into any one of a number of grooves 26. To move the connector 19 from the position shown in Fig. 2 to that in which terminals 10, 15 are bridged, the shaft 18 is rotated clockwise, and, as contacts 20, 21 remain in engagement with their respective terminals 10, 11, the connector 19 is rotated counterclockwise until the roller 24 gets level with the groove 26 next the terminal 13. Further rotation of shaft 18 moves the roller 24 into that groove and the contacts 20, 21 out of engagement with terminals 10, 11 and into engagement with terminals 10, 15, the roller moving out of the grooves to a position half-way towards the groove next terminal 12. The lower ends of the terminals 10 .. 15 are cut away and provided with arcing contacts 34 for co-operating with movable arcing contacts 27 on an arm 29 freely rotatable about the shaft 18 below the offset part. A groove 32 in the arm 29 is formed with an enlargement 33 in which a pin 31 on the connector 19 engages with a certain amount of play. The connector 19, in changing position, moves its contacts 20, 21 out of engagement with their terminals, leaving the arcing contacts 27 still in engagement with their terminals 34. When the roller 24 enters a recess 26, the pin 31 enters the narrow part of groove 32 and drives the arcing contact 27 into the next position with the main contacts, but the latter does not make contact until the pin 31 again leaves the narrow part of groove 32, so that the circuit is both made and broken at the arcing contacts. Specification 23942A/96, [Class 38, Electricity, Regulating &c.], is referred to.

Title: Improved balancing machine
IPC: G01M1/08
Filed: 1963-07-26
Abstract: 966,847. Machines for testing balance. A. PAOLICCHI. July 26, 1963, No. 29824/63. Heading G1X. [Also in Division F2] A balancing machine comprises an electric motor 10 mounted with its shaft 12 horizontal, and so that it has limited rotational movement about a vertical axis, a plate 31 with a flange 32 and lock nut 33 for mounting the object to be balanced at one end of the shaft 12 and recording means fitted to the other end of the shaft. The motor 10 is mounted on spigots 15, 16 inside a casing 11, the motor having bearings 13, 14 to engage with the spigots, and the bearings being preloaded by springs 17, 18. The lower spigot 16 is adjustable, its adjustment being indicated by a pointer 46, to vary the bearing loading and thus the sensitivity of the machine. The movement of the motor about the bearings 13, 14 may be resisted by helical torsion springs 17a, 18a, by coiled compression springs or by rubber buffers (not shown) or by a combination of these. In use, with the object to be balanced mounted on the plate 31, the motor 10 rotates the shaft 12. When full rotational speed has been reached the motor current is switched off and the shaft allowed to slow down. At the critical speed the unbalanced object will cause pivoting of the motor 10 about the bearings 13, 14 and this movement will be recorded by a spring loaded marker pencil 37 held in line with the axis of the shaft 12 when stationary, on a disc of graph paper secured to a disc 34. An "apple-shaped" graph will be obtained (Fig. 5), and an indicator gauge 44 may be positioned in front of this graph, and the shaft 12 rotated to position the lobes of the graph on the line A-A as shown in Fig. 5. An indicator arm 45, Fig. 1, then indicates the position at which weight must be added to the object to balance it. The value of such weight can be determined from the graph and the concentric lines on the graph paper. A disc 30 may be provided on the shaft 12 for braking purposes and where heavy objects are to be balanced a centrifugal clutch may be interposed in the shaft 12 to avoid damaging the motor. The clutch may be effectively locked solid as the motor shaft runs down. The machine may also be used to correct for static unbalance by allowing the object on the plate 31 to rotate and come to rest freely so that.the heaviest part is lowermost. Australian Specification 222,903 is referred to.
