Title: Mounting assembly for supporting a body to be balanced in a balancing machine
IPC: G01M1/04
Filed: 1973-04-05
Abstract: 1420418 Measuring unbalance in rotated bodies HOFMANN GmbH Gebr [trading as HOFMANN K G MASCHINENFABRIK Gebr] 5 April 1973 [3 May 1972] 16367/73 Headings G1N and G1X A mounting assembly for a balancing machine to determine unbalance of a rotated body 1, comprises a rotary-spindle 3 supported within a frame 4 which is itself supported by first and second support assemblies at least the first of which permits displacement of the adjacent portion of frame 4. A force measuring means 18 is associated with each support assembly, each means 18 having its measuring direction perpendicular to the spindle axis, the arrangement being such that the frame 4 transmits forces due to unbalance of the body 1 to the means 18 via the support assemblies which are non-transmissive of a torque applied to the frame 4 by forces thereon in the measuring direction of the other support assembly. Thus forces acting on each means 18 does not influence the other means 18. A computer, given the dimensions of the body 1 may then calculate the unbalance thereof at any plane which is parallel to the measuring planes. Brackets 16, 22 are rigidly supported against movement perpendicular to means 18 by spring members 23, 24. The required displacement of the frame adjacent a support assembly may be achieved by a radial play in the bearing means of the associated assembly or, as shown, bearing assemblies 12, 13 of one assembly may be located in a respective connector 17 each of which forms a connection between a respective guide 14, 15 and assemblies 12, 13.

Abstract: 209,705. British Thomson-Houston Co., Ltd., (Assignees of Guay, E. J.). Jan. 10, 1923, [Convention date]. Toothed wheels and pinions.-In forming gear blanks of layers of cotton duck or canvas or other fabric previously coated or treated with a, phenolic condensation product such as bakelite or other equivalent binder, rings or washers of the fabric of equal or various annular widths and'of a diameter corresponding to that of the rim and/or the hub of the gear, are interspersed with discs of the fabric having central holes either in the form of small shaft openings or larger openings for a central metal binding or support, such discs forming the web of the gear whilst the rings of fabric interspersed therebetween cooperate with the discs to form broader rim and/or hub parts, as shown in Fig. 9. One or more of the outer fabric discs may be previously dished by heat and pressure to the external form of the gear blank. In assembling, the outer dished discs, the inner flat discs and the interspersed washers are arranged in a casing or holder, Fig. 7, being positioned by a central stud 23 and adapted to be compressed between plates 19, 21. The process of binding the assembled parts into a solid and highly polished blank by pressure and heat is described in detail, examples of suitable temperatures and pressures being given. The process of coating the fabric with the binding agent is also described, with particulars of suitable qualities and proportionate weights of the binder and fabric. The gear blank may be formed without a thickened hub so that it can be bolted to a flange or plate as in the timing gear train of small motor vehicles or, as shown in Figs. 7 and 9, the thickened hub 16 may be formed on a flanged metal bush or lining 24 which may be externally roughened to effect a bond with the fabric. In assembling this arrangement, the metal lining 24 is clamped between a shoulder on the stud 23, Fig. 7, and the bottom plate 19 to prevent displacement when pressure is applied. The interspersed rim washers or rings may be stamped or cut from the sheet complete or in segments which are afterwards assembled with butt joints staggered in adjacent layers, or they may be formed from strips of material by winding edgewise in helical manner on a mandrel, Fig. 3. Alternatively a strip or tape may be moistened and wrapped round a thin flat former which is subsequently wound in the form of a helix of the desired diameter, Fig. 6, the helix being then cut to form washers each having only a single joint.

Title: Improvements in or relating to remote control tuning arrangements particularly for high frequency apparatus
IPC: H03J1/18
Filed: 1938-06-07
Abstract: 515,693. Electric control systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 7, 1938, No. 16895. Convention date, June 5, 1937. [Class 40 (i)] In a remote control system for tuning wireless receivers of the automatically balanced bridge type, the bridge relay which controls the driving motor is locked operated when the bridge is out of balance. As shown, in Fig. 1, a tapped control resistance 5 and a resistance 6 automatically adjusted by a motor 23 which drives the tuning element are connected in a bridge circuit with a battery 13 and a bridge relay 16, which controls the motor. A battery 20 and a current limiting resistance 21 are connected across the relay 16, the current from the battery 20 being insufficient to operate the relay, but capable of locking the relay when the latter is operated by the bridge. When the balance is upset by operation of the contact arm 14, the relay is pulled up over the current 15, 17 and the motor 23 is operated to drive the arm 18 of the resistance 6 until balance is restored. When, during operation, the relay circuit 15, 17 is opened by the passage of the arm 18 over the space between neigbouring contacts of the tapped resistance 6, the relay 16 is maintained operated by the battery 20 but when the balance point is reached and no potential difference exists between the arms 14, 18, relay is shunted by the resistances 5, 6 and the locking current in the relay is reduced sufficiently to allow the relay to release and stop the motor. A reversing arrangement may be provided in order to effect a reverse movement of the arm 18 when it reaches a limit of movement. One or both of the leads 24, 25 may be dispensed with by utilizing the chassis of the receiver, providing a separate battery for supplying the resistance 6 or employing an earth return. In a modification a polarized bridge relay is provided and the auxiliary source 20 is omitted. The polarized relay is provided with an additional contact which controls the locking circuit of the relay. Instead of resistances tapped impedances may be employed and push button switches may be used instead of. the arm 14. Fig. 3 shows a form of switch 18 wherein back-lash is prevented. A slider 70 carrying a pivoted contact 74 is operated by the motor through an endless belt 71. The contact co-operates with adjustable stops 76, 77 and with the contacts 73 of the impedance. The arrangement is such that by suitable adjustment of the stops, the flexible tip 78 of the contact 74 engages a contact 73 only when the pivot 75 is directly over the contact independently of the direction of approach. The electrical connection to the contact arm is preferably made through the stops 76, 77.
