Abstract: 727,526. Automatic exchange equipment. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 25, 1953 [Feb. 29, 1952], No. 5265/53. Class 40 (4). In an automatic exchange wherein speech currents traverse the discharge path of a discharge tube 13, busy tone from a generator 36 is applied to a subscriber's line 1, 2 through an element 31 controlled by the combination of potentials at points 37 and 38 in the subscriber's line and discharge tube circuit respectively when the subscriber's loop is closed but the discharge path is not rendered conductive. The surge arising in the subscriber's line circuit when the line loop around battery 7 is closed by the lifting of the handset fires tube 13, and subsequently dialled digits are applied to a marking switch 29 which, by applying a potential to the appropriate outlet, fires by means of a striking electrode 24 a tube appropriate to the wanted subscriber which has its anode commoned to point 17. The wanted connection is thus established across the common point. Tube 13 in striking raises the cathode potential to 50 v. by the current flow through resistor 14 so that calls by other subscribers over other marking switches seeking to fire the other tubes multipled at 11 are prevented. The setting up of other calls over the same connecting circuit is prevented by the drop in anode potential at point 40. Point 37 in the subscriber's line equipment is maintained at - 30 v. by resistor 8 when the subscriber's loop is closed.

Title: Improved manufacture of rubber chloride composition
IPC: C08K5/00
Filed: 1937-02-22
Abstract: Rubber chloride is blended with a minor amount of a miscible softener in the presence of a solvent in an amount which is insufficient to cause the rubber chloride to become the disperse phase of a dispersion, the softener being a liquid or soft solid with substantially no vapour tension at ordinary temperatures. The blending may be effected at 60-90 DEG  C., yielding a thermoplastic solid which may be dispersed in a volatile solvent to form a varnish. Suitable softeners are esters of aliphatic acids with ether-alcohols, or chlorine derivatives thereof, or aromatic or aliphatic esters of dichlorhydrin, many suitable esters being specified.  A nonmiscible plasticiser, such as tricresyl phosphate, may replace part of the softener.  Suitable solvents are hydrogenated naphthalene, p-cymene, and monochlornaphthalene, if desired with a more volatile solvent such as xylol.  In making a varnish, the rubber chloride blend may be dissolved in a mixture of p-cymene, solvent naphtha, toluol and xylol.  The esters of dichlorhydrin may be prepared by reaction of dichlorhydrin with the corresponding acid chlorides. Specification 491,075 is referred to.ALSO:Rubber chloride is blended with a minor amount of a miscible softener in the presence of a solvent in an amount which is insufficient to cause the rubber chloride to become the disperse phase of a dispersion, the softener being a liquid or soft solid with substantially no vapour tension at ordinary temperatures.

In a motor vehicle change speed gear, such as described in Specification 1,061,379, wherein, for upshift, automatic actuation of a relay 5 responsive to engine speed and torque energizes a solenoid valve 12 to engage an hydraulically actuated friction clutch 3 and simultaneously energizes a solenoid 15 to close an auxiliary throttle valve 16 for engine torque reduction, a piston 13b in a cylinder 13a is acted on against a spring 13c by the hydraulic pressure effecting clutch engagement, the arrangement being such that only when the clutch is completely engaged is said pressure high enough for the piston to open, by its rod 13d, contacts 14 in the circuit of the solenoid 15 and thereby reopen the auxiliary throttle valve. A range-shift lever 1 selects Neutral, PM; Low Range, GB, for 1-2 automatic shift; and High Range, GH, for 3-4 automatic shift. In 1st and 3rd gear, drive is through an hydraulic converter/coupling (not shown) the turbine of which is connected to a shaft 2. In 2nd and 3rd gear, drive is through the hydraulically actuated friction clutch 3. In operation, with the vehicle stationary the hydraulic converter/coupling drives the shaft 2 at idling speed and a vehicle-stop detector switch 7 is closed. On shifting the lever 1 to Low Range, GB, closure of a shift lever switch 6 energizes a relay 8 through the closed switch 7 to open a solenoid valve 9 to apply an hydraulic brake 10a, 10b to the shaft 2 to enable 1st gear to be engaged. As soon as the vehicle travels at a predetermined speed, the switch 7 opens, the brake 10a, 10b being needed only for starting. On actuation of the automatic relay 5, a relay 11 effects the abovementioned clutch and auxiliary throttle valve operation. On continued vehicle acceleration, the lever 1 is shifted to High Range, GH, and drive is firstly in 3rd gear, through the hydraulic converter/ coupling, the relay 5 opening to effect exhaust of hydraulic pressure to disengage the clutch 3 and return of the piston-rod 13d in readiness for 3-4 shift.

Filed: 1975-02-12
Abstract: 1490399 Stereophonic receivers SONY CORP 12 Feb 1975 [15 Feb 1974 (2)] 5966/75 Heading H4R In a stereophonic FM receiver a frequency discriminator supplied with a conventional stereo signal comprising a base band signal a 19 kHz pilot, and a sub-channel signal amplitude modulated on a 38 kHz sub-carrier, produces a pair of stereo composite signals of opposite polarity at its output terminals, which are fed to respective stereo demodulators each supplying L and R channel output signals, each channel containing cross-talk from the opposite channel. One of the stereo composite signals is attenuated prior to the stereo demodulation and the outputs of the demodulators are combined so as to cancel the cross-talk components in the combined outputs. As described, the discriminator 1, Fig. 1, is a ratio detector the output of which is developed across resistor 18, the tapping point of which is earthed to provide at the points 1a, 1b, opposite polarity stereo composite signals the amplitude ratio of which is adjustable by movement of the tapping point. A conventional phase lock loop comprising a phase comparator 22, controlling a 76 kHz oscillator 23, which feeds a flip-flop 24, and two series connected divide by two stages 25 and 26, provides a 38 kHz switching signal to control the switches SW1, SW2, SW3, SW4 in the two stereo demodulators fed respectively with the opposite phase composite signals via respective resistors 19, 20. The resulting pairs of L and R signals are combined in adders AD1, AD2, to provide the L and R signals at output terminals 29L, 29R, from which cross-talk components have been cancelled. In a modification, Figs. 2, 9, and 10 (not shown), the D.C. level of the two composite signals on the discriminator output is balanced by providing balanced resistors (30, 31 or 50, 51) to earth from the discriminator output terminals and the signal level is adjusted by an A.C. attenuator (32, 33). The switches in the stereo demodulator are preferably MOS fets supplied on their gates with the switching signals, using single or multiple arrangements of fet's, Figs. 3, 5, 6, 7 and 8 (not shown).
