Abstract: 1,163,834. Bearings; torsional vibration dampers; shaft couplings. ROBERT BOSCH G.m.b.H. 26 Oct., 1966 [9 Nov., 1965], No. 47947/66. Headings F2A, F2S and F2U. [Also in Division H2] The double supply frequency vibration inherent in an A.C. commutator motor is absorbed by an elastic element provided in the drive between the rotor of the motor and a gear transmission. The motor has a housing 1 of insulating material and a rotor mounted on a hollow shaft 8 and co-operating with stator assembly 2. A hollow stub shaft 10 is mounted in bearing 11 and is connected to hollow shaft 8 by means of flanges having an interposed resilient member 9 which may be made of rubber. The hollow shafts are located by a rigid glass-fibre rod 22 which in a modification only extends into the parts of shafts 8, 10 immediately adjacent the flanges, Fig. 3 (not shown). The remote end of shaft 8 is mounted in needle bearing 23 supported in sleeve 24 which is resiliently mounted by means 27 in the housing. The sleeve 24 has arms 25 which support the brush-holders and brushes 26 are pressed against commutator 6 by means of springs 28 through an interposed resilient element 30. A cooling fan 31 may be mounted on the resilient member 9. A layer of insulating material 7 is interposed between rotor core 4 and hollow shaft 8.

Abstract: 1,039,519. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. Dec. 6, 1963 [Dec. 21, 1962], No. 48432/62. Heading B3M. A horizontal rolling mill includes structures 15 and 16 supporting rolls 11 and 12, the structures being interconnected so that during roll removal the lower structures are supported by the upper ones. The upper structures 16 are prestressed to generally U-shaped frame members 14, and the connection between the upper and lower structures allows relative axial and lateral movement between them for adjustment of the rolls during rolling. For changing the rolls, the nuts of prestressing bolts 17 and 18 are loosened and the generally T-shaped structures 16 are lifted by hooks 22, the structures 15 being suspended by links 21 from the structures 16. In place of slotted links, headed bolts may extend vertically from the structures 15 through bores formed in lateral extensions of each structure 16. The lower roll 11 is adjustable relative to the upper roll 12 by means of slidable wedges, both rolls being axially adjustable.

Title: Reactive power compensation

Filed: 1975-12-05
Abstract: 1535739 Automatic control FRAKOKONDENSATOREN-UND APPARATEBAU GmbH 5 Dec 1975 50115/75 Heading G3N [Also in Division H2] A control circuit for a reactive power regulating system comprises an up/down binary counter 11 which is caused to count in the appropriate direction in response to an increase or decrease in the reactive current detected at 1, 2 and an output circuit which is used to control any of three different arrangements of compensating elements connected via terminal boards, R1, R2 or R3 whereby the output of the counter is used to switch in the appropriate value of compensation for the detected current. With a set of capacitors having values in the ratio 1:2:4 the binary signals from the counter are fed directly to board Rl to perform the switching. With a set of capacitors all having the same value, a connecting block 21 carries the signals to a binary to decimal converter 24. An output on the appropriate decimal line then causes that number of capacitors to be switched in via the diode matrix 26. Capacitors in the ratio 1:2:2 can be accommodated by connecting each output of the counter via block 21 to the next lower binary value input of the binary to decimal converter 24 and using the resulting output together with the unmodified least significant digit from the counter to select appropriate capacitors at R2. The connection at 21 is by means of inter-changeable printed circuit boards. Gates 9À2, 10À2 provide for a manual operation of the counter, via push buttons S1 and T1 or T2 while gates 9À3, 10À3 cause the counter to stop counting forwards at a predetermined number and to stop counting back at zero. The predetermined number corresponds to the value of capacitance available, a maximum of 15 units may be accommodated in the system illustrated, and this or any smaller number may be programmed by suitable inter-connection of terminals SQ1, SQ2, ... SQ4 with terminals SV in the block 23. This inter-connection is also effected with interchangeable printed circuit boards.
