Title: Improvements in or relating to systems of distributing electrical signals
IPC: H04H40/27
Filed: 1928-11-16
Abstract: 319,984. Warwick, A., Taylor, J. A. A., and Holmes, H. C. Nov. 16, 1928. Systems for transmitting music &c.-The detected signals from two or more wireless receivers are distributed over a wire line to a number of listening-stations, one or more of the sets of signals being raised in frequency by modulation to prevent interference between them. As shown, two wireless receivers a, a' are tuned to receive different broadcast programmes. The detected output from receiver a passes through chokes a<2> to a line f. The output from receiver a<1> passes to a modulator c and modulates a locally-produced wa.ve of supersonic frequency, and the resultant wave passes through condensers f<2> to the same line f. At a listening- station A the programme from receiver a is heard by moving switch arm Z to contact Z<1>, thereby connecting an amplifier l with loudspeaker d across the branch line h. To receive the other programme, the switch Z is moved to contact Z<2>, and the modulated wave passing through the tuned bridge n, k, is rectified by a crystal or other detector x which feeds tha amplifier l and speaker d.

Title: Improvements in or relating to rotary pumps
IPC: F04C2/08
Filed: 1945-12-14
Abstract: 605,104. Toothed gearing. KEELAVITE CO., Ltd., and JOHNSON, E. H. Dec. 14, 1945, No. 33886. Drawings to Specification. [Class 80 (i)] [Also in Group XXVI] In a rotary pump of the gear-wheel type, the compression of liquid in the spaces between adjacent lines of sealing contact of the intermeshing teeth is reduced or prevented by cropping the teeth of the driven gear-wheel, leaving them otherwise of the normal involute form for a gear of the diameter which the gear would have in its uncropped form, while the teeth of the driving gear are uncropped. The extent of the cropping may be such that the sealing flanks of each pair of teeth do not come into engagement until the line of sealing contact of the preceding pair lies a small distance (not greater than that represented by 2 degrees of gear.wheel rotation) in advance of the plane which is common to the axes of the gears. The cropping may be effected by reducing the diameter of the gear-wheel before or after the teeth have been cut or at an intermediate stage or partly by one or more of these methods. There may be more than two gears, and the gears may have different pitch diameters.

Filed: 1976-08-16
Abstract: 1506194 Change-speed gear control TWIN DISC Inc 16 Aug 1976 [29 Sept 1975] 33994/76 Heading F2D [Also in Division G3] An automatic vehicle transmission, which comprises a change-speed gear P driven by an engine E through a torque converter TC having a lock-up clutch LC, has manually selected reverse, neutral and first gears and is automatically controlled in higher forward gears (second to sixth) in dependence on the manual setting of a range selector ERS, which sets the highest gear which can be engaged, the condition of a throttle position switch TPS which prevents upward changes when the accelerator pedal is not depressed and the speed of the transmission output shaft SH. The output shaft speed is supplied as electrical pulses from a pick-up A, these being amplified, shaped and supplied to a counter D whose count is supplied, every half second, to a speed matrix F, G (Fig. 3, not shown). The speed matrix supplies upshift or downshift signals to shift logic H (Fig. 4, not shown). The shift logic H also receives signals from the accelerator pedal, and allows no upshifts unless this is depressed, and the range selector ERS which sets the highest gear which can be selected. The gears are engaged by valves controlled by solenoids M which are operated by solenoid drivers in turn controlled through a decoder J (Figs. 4 and 5, not shown). The circuitry includes means for preventing engagement of reverse (or of any other manually selected gear) above predetermined vehicle speeds. An override connector (OS, Fig. 6, not shown) may be connected to the controller EC by an operator to make all the gears manually selectable. The lock-up clutch engages hydraulically at a predetermined converter turbine speed, as sensed by a pilot device PM.

Title: Improvements in electric warp stop-motions for looms
IPC: D03D51/00
Filed: 1921-12-29
Abstract: 174,335. Bourgeois, C. Jan. 13, 1921, [Convention date]. Stop-motions, warp.-A device for stopping a loom when a warp thread breaks comprises a metal frame 1, 2 supporting fine steel wire springs 12, around each of which is wound one of the warp threads, as shown at b. The pull of each thread keeps its spring deflected, as shown at 12<b>, but, on the breakage of a thread, its spring returns to the position 12<a> and contacts with a metal bar 8 completing an electric circuit through the frame 1, 2 and the bar 8, to stop the loom. At the top and bottom of the frame are five parallel metal strips 3 spaced apart to form four gaps 4 and secured by screws 6. The springs 12 have hooked ends, which engage in the gaps 4. Certain of the springs 12<a> pass to the left of the central strip 3 in the top group, their upper ends 13<a> engaging the right-hand gap, while at the bottom they pass to the right of the central strip, their lower ends engaging the left-hand gap. The intermediate springs 12<b> pass through the opposite slots, so that adjacent springs cross and thus maintain their relative positions. The bar 8 is supported by blocks 7 of wood or other bad conductor, and it presses against any spring not pulled away by a thread. The ends of the bar 8 are surrounded by sleeves 16 of Chatterton's compound, rubber &c. so that any springs not used can be slipped to the ends of the frame and insulated from the bar 8. The frame 1, 2 is supported in channel-members 9 attached to uprights, and preferably is inclined with its top towards the healds, so that the coil b of thread is kept open to prevent friction between the portions of thread. Combs are inserted at intervals between the strips 3 so as to maintain the gaps 4 at their correct widths. Pairs of rigid metal wires may be substituted for the metal strips 3.
