Title: Improvements in and relating to dynamo electric machines
IPC: H02K3/20
Filed: 1930-05-20
Abstract: 359,988. Dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Taylor, H. D.; 1358, Dean Street, Schenectady, New York, U.S.A.) May 20, 1930, No. 15492. Convention date, May 20, 1929. [Class 35.] Cores.-In a salient pole dynamo-electric machine, open unwound slots are provided in the periphery of the poles to reduce noise due to variations in the radial magnetic pull between the two members of the machine. These slots are so situated as to minimize the variations of the reluctance of the magnetic path from the peripheral portion of the pole to the corresponding part of the core of the other member for all the relative positions of the salient pole and non-salient pole members. In the form shown in Figs. 3 and 4 variation of the flux path is caused by the slots 17 which are only ineffective when the salient pole 13 is in the position shown in Fig. 3. This variation is counteracted by empty slots 18 spaced approximately half a tator tooth pitch from the slots 17. In the form shown in Figs. 7 and 8, the flux distribution is disturbed by the slots containing the conductors 20 when the pole 19 is in the position shown in Fig. 7, which is also the position when the pole is presented to the minimum number of teeth. Fig. 8 shows the pole 19 moved through half a stator tooth pitch so that the pole is opposite four teeth 16. To counteract these inequalities, the conductor containing slots are plugged with magnetic material 23 and empty slots 24 are provided which are only effective when the number of teeth opposite the pole is greater than the mean number. When a pole without a pole-face winding is used, unwound open slots are provided so as to be effective when the pole is opposite the larger number of stator teeth, the slots being approximately a stator tooth pitch apart. Reference has been directed by the Comptroller to Specifications 104,535 and 232,794, [both in Class 35, Dynamo-electric generators &c.].

IPC: B01D45/14
Filed: 1966-04-07
Abstract: 1,137,974. Rotary filter, centrifugal separator. ARTHUR D. LITTLE, Inc. 7 April, 1966, No. 15750/66. Headings B1D, BIT and B2P. An inward-flow rotary filter drum 25 carries a pair of vertical baffles 50 which maintain fluid in the annular space around the drum in rotation therewith, and the drum is rotated at a speed which either prevents solid particles landing thereon, for normal filtration, or allows particles below a certain size to land or pass through, for solid particle classifying. A similar technique may be used to establish a layer of filter aid, or separated solids acting as filter aid, on the drum, which layer is periodically removed or disturbed by varying the speed. In Fig. 1, slurry enters the housing at 22, filtrate is withdrawn through hollow, rotary shaft 44 and solids or rejected slurry accumulate in a non-turbulent zone, defined by baffles 65, 66, and are removed through a valve (not shown). In Figs. 6, 7 (not shown), also for liquid filtering, a rotary, scroll-like scraper (88) directs solids across the flat floor of the housing, through holes (98) into chamber (83), whose outlet valve (104) is controlled by a timer and differential pressure switch, which detects the rising level of material in chamber (83). The scraper and chamber may be periodically washed out by liquid from inlet (95). In Fig. 8 (not shown) a gas filter incorporates a scraper (88) and continuously rotating dust-outlet valve (122). The drum 25 has a layer (26) of filtering fabric supported between two foraminous screens (27, 28) on a perforate support 29.

Title: Impulse-Pair Detector
IPC: G01S13/78
Filed: 1967-04-06
Abstract: 1,158,759. Circuits responding to particular signals. INTERNATIONAL STANDARD ELECTRIC CORP. 6 April, 1967 [13 April, 1966], No. 15791/67. Heading G4H. [Also in Division H4] An impulse pair detector for use in radio navigation comprises a shift register 7 to which the first pulse is applied, the shift register being driven by clock pulses from source HD and the outputs 8 from the stages thereof being gated at 9.1, 9.2 &c. with the input line 4b to give a signal when one of the shift register output coincides with an input pulse. When a pulse pair is detected a second source of clock pulses HC and a second group of gates 10.0, 10.1 &c. is coupled to the shift register to generate a modulated reply signal. The input at 1 is applied via gate 2 and/or gate 5 to the shift register. An input pulse, whether one of a valid pair, or a spurious pulse will enter a " 1 " in the shift register and set flip-flop 16. This energizes the third input to gates 9.1 &c. and unblocks gate 14 so that pulses from source HD are applied to stop the register. If a second pulse coincides with the "1" in an appropriate stage of the shift register or gate 9.1 &c. gives an output to set flip-flop 24, closing gate 2 and preventing any more pulses reaching the shift register. A spurious pulse, which is not followed at the proper interval by another pulse passes to the end of the shift register and at output F resets the circuit to its initial condition. The signal on line 25 also resets flip-flop 16 and opens gate 26 to allow pulses from source HC to pass to the stepping input of the shift register for the second phase of operation in which a single pulse entered from flip-flop 30 passes in turn through each stage giving successive outputs from gates 10.0 &c. These are held open by the signal on line 25. The distributed signals from gates 10.0, 10.1 &c. are applied to stages 13.0, 13.1 &c., some of which are set to "1" and some to "0" so that a reply pattern of 1's and 0's is sent in response to the reception of a valid pair of pulses.

Title: A new or improved friction device
IPC: F16D13/52
Filed: 1953-06-11
Abstract: 728,875. Friction clutches. LAMBERT BRAKE CORPORATION. June 11, 1953 [June 11, 1952], No, 16171/53. Class 80 (2). A friction clutch comprises a plurality of discs 12, 13, splined at 10, 11 to inpizt or output members 4, 8 respectively, engaged initially by springs 38, 39 self-energization by cam balls 43. following, the discs running in oil and having passages therefor-extending therethrough. The engaging springs 38, 39 act between a member. 23 and a plate 18 freely mounted on the member 8. The member 23 is keyed at 24 to the member 8, but is adjustable axially by means of a nut 27 locked, by a tab washer 28. The line of action of the springs is inclined to the axis of the clutch whereby a rotation of the plate 18 relative to the member 23 occurs upon initial movement. This rotation causes the cam balls 43 to ride up cam faces 42 on the members 18, 23 and self-energization of the clutch follows. Spring force is transmitted through caps 36 having spherical seats 37 engaging projections 34, 35 on the members 1,8, 23. To disengage the clutch a lever 64 is rocked about pivots 65, thus transmitting an axial force to the plate 18 through trunnions 63, ring 59, thrust bearing 55 and bolts (Fig. 6, not shown) connecting the plate 18 to the member 44. The discs 12 have holes 69 disposed within the inner periphery of the discs 13 to give a continuous passage for oil from end to end of the clutch discs. Holes 66, 67 and 68 in the member 4 and plates 17, 18 allow entry of oil to the discs. Helical grooves 70 are formed in the friction faces, which are preferably of brass, of the discs 13. The oil film on the discs is rapidly forced into these grooves upon engagement. Input or output shafts are received by splines 5, 9 on the members 4, 8.
