Title: Output filter
IPC: H03H7/46
Filed: 1962-03-15
Abstract: 961,735. Filter networks. COLLINS RADIO CO. March 15, 1962 [Aug. 2, 1961], No. 10027/62. Heading H3U. A frequency-separating circuit, e.g. for frequencies of the order of 100 c.p.s., comprises a push-pull input connected as shown to a number of frequency-selective transformers. Each transformer comprises a single secondary winding and a pair of primary windings, either the primaries or the secondaries being tuned to the separate frequencies. Primary windings 76, 79, 82, 85 &c, are connected in series in the same sense between one pole 74 of the pushpull input and the common pole 99, whilst the other windings 77, 80, 83, 86 &c. are connected in series in the opposite sense between the other pole 75 and the common pole 99. The last pair of primary windings 85, 86 may be formed as a single centre-tapped winding.

Title: Methods and apparatus for handling yarns
IPC: D01D10/04
Filed: 1951-05-01
Abstract: 693,399. Yarn-storage and advancing apparatus &c. AMERICAN VISCOSE CORPORATION. May 1, 1951 [July 6, 1950], No. 10201/51. Class 120(ii) A method of handling a plurality of yarns together on a yarn-storage, yarnadvancing device having a certain pitch is characterised in that the yarns are directed to one end of the device spaced apart from each other a distance that is approximately equal to a whole number times the pitch, a plurality of turns of the yarns being formed on the device, and the yarns being; brought together by shifting the position of one of them laterally along the device a distance approximately equal to a whole number times the pitch of the device. As. shown, filaments A, B from spinnerets 1, 2: are guided to a reel 5, which may comprise interdigitating bars, rotating about eccentrically inclined axes, the filaments then being led to the device 7 (which may be similar to the device 5) in spaced relationship, the filament B passing through the notch 9 of the guide member 6 and the filament A through the notch 8 thereof. The filaments A and B, after several revolutions of the device 7, advance side by side, towards the discharge end of the device 7. Filament A is now removed from notch 8 and placed with filament B in notch 9. In similar manner, at a later stage, the yarns A, B, which were delivered from device 7 to device 10, in spaced relationship, are subsequently moved into the same notch in the guide 11 (see Fig. 2). Again, the yarns A and B, which were delivered together from the device 10 to the device 12, comprising rotatable drums 14 whose axes are canted with respect to each other, are guided firstly by a single notch in the guiding device 13, but are subsequently separated into two notches in the guide 13 and later wound up on to separate packages 15. This method of handling a plurality of yarns during treatment allows of the length of the devices to be reduced.

Title: Lubricating equipment
IPC: F16N25/00
Filed: 1966-03-09
Abstract: 1,135,492. Bearings; valves. JOSEPH VOGELE A.G. 9 March, 1966 [20 March, 1965], No. 10291/66. Headings F2A and F2V. A lubricating system comprises branch-pipes 6 and 7, Fig. 1, which are connected to a main pump pipe 5; lead to lubrication points 15, either directly or through piston distributors 8 ... 12, and via outlets 13 and pipes 14; and each of which has a quantity regulating valve 18 incorporated therein. The main pump pipe 5 is supplied with pressurized lubricant from a tank 3 via a pipe 4 and a pump 2 which is driven by a motor 1; excess lubricant being returned to the tank 3 via a pipe 16 and a pressure-limiting valve 17. The quantity - regulating valve 18, Figs. 2 and 3, consists of a casing 20, having a longitudinal bore 21 which contains a sleeve-valve 22, a spring 23 and an interchangeable throttle member 24 and closing-screws 25, 26 therein. The casing 20 also has a longitudinal bore 27 which contains a screw-in filter 28, a transverse supply bore 29, a transverse discharge bore 30 and a bore 39 which connects together the longitudinal bores 21, 27. In use, lubricant is supplied to the casing 20 through the bore 29 and passes through the filter 28, the connecting bore 39 and the throttle member 24. The restriction of the latter causes a pressure build-up and the sleeve-valve 22 is moved to the right against the force of the spring 23. The lubricant which flows through the throttle member 24 passes to the discharge bore 30 via an annular groove 40, the latter being constricted to a greater or lesser extent by the movement of the sleeve-valve 22 so that the rate of flow is maintained constant. The sleeve valve 22 is only set in motion when the desired quantity of lubricant flows through the throttle member 24 and thus a warning device, which includes an electric switch 19, is inoperative. If the quantity of lubricant flowing is insufficient, the sleeve-valve 22 actuates a pin 32 which closes the switch 19 to energize a warning light.

Manually operable switches 19, 20 associated with respective lock release mechanisms 29, 30, are situated either in the lift car, in the motor room or at the respective landing level, and are operable via security devices, by authorized persons only, these switches operating the solenoids of respective lock release mechanisms 29, 30 whereafter the respective landing doors 17, 18 may be manually opened. In a modification, Fig. 4 (not shown), a second switch (27) either on the lift car or mounted in the lift shaft and set in series with the switch (19) or (20) in the circuit of each release mechanism, has to be closed before the associated door lock release mechanism solenoid can be energized. This closing is effected either by control cams, in the shaft, or by control cams on the lift car, as the car reaches the appropriate position in the shaft. A warning lamp may be set in series with each switch (27) to indicate the switch operating position of the lift car. The switches (27) may alternatively be operated magnetically or optically. In further embodiments, Figs. 6 and 7 (not shown), the switches (19, 20) are set in series with safety contacts (32, 33) to prevent movement of the lift car when one of the switches (19, 20) has been operated, or the switches (19, 20) may be further interlocked to prevent each lock mechanism being released unless the lift car has stopped.
