Abstract: 1,250,350. Phase equalization. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES. 31 Dec., 1968 [3 Jan., 1968], No. 61952/68. Heading H4R. In a receiver for signals in which the phase of the received carrier is dependent on the signal conditions in two data signal channels, and in which the receiver includes two demodulators 5 and 6 fed with quadrature related signals from a local oscillator 10 in order to demodulate the two data signals, delay time equalization is provided by an equalizer 20 which provides a delay time versus frequency characteristic of the received signal which is symmetrical about the carrier frequency, which removes cross talk between the two channels, while further equalizers 27 and 28 are provided in the respective channels after the demodulators to give a constant delay time versus frequency characteristic across the received band, which gives optimum pulse shape to the received signal. As described the system comprises two data channels of synchronous pulse signals at 2 kHz, which modulate two carriers of the same frequency e.g. 1À9 kHz but in phase quadrature, the signals being combined for transmission to the receiver. At the receiver the phase equilizing networks comprise fixed equalizers of the type shown in Fig. 2a and variable equalizers of the type shown in Fig. 2b. Since the common equalizer 20 provides a phase characteristic symmetrical about the carrier the equalization to be provided by equalizers 27 and 28 is identical and their controls can be mechanically coupled. After equalization the received signals are regenerated in 13 and 14 before passing to the utilization devices 11 and 12. The arrangement allows the use of simpler equalizers than if all the equalization was provided before the demodulators.

During a braking cycle, pressure in chamber 34 is equal to that in chamber 32 and piston 20 remains in a centered position. However, should a malfunction occur in the front system 110 pressure in chamber 34 would decrease and the piston 20 move so that a shoulder 30 engages a switch arm 25 to actuate a warning device 114. The valve member 66 is also moved with spring 84 against a spring 62 and piston 86 cannot follow owing to the engagement of a shoulder 96 with a stop ring 98 so that fluid communication is permitted through bore 92 and the proportioning function of the valve is eliminated so that the rear brakes can deliver maximum effort.

Abstract: 1,266,847. Magnetic storage arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 28 Oct., 1970 [31 Oct., 1969], No. 51160/70. Heading H3B. In a three co-ordinate store in which writing is effected by simultaneously energizing with ¢- write currents an x and a y conductor common to the store planes, and writing in a particular plane is prevented by energizing a z inhibit conductor individual to the plane, all the z inhibit conductors required to be effective during a writing operation are connected in series with the x and y conductors so that the inhibit current is equal to the ¢ write current. Storage planes 1, 2 ... P are shown in Fig. 1, a selected x and a selected y conductor being series energized from a ¢-write current source It when a switch Sx and a switch Sy are selectively closed. Writing takes place when ganged switches Sw 1 , Sw 2  are in the position shown, the switch Sw 1  connecting the selected x and y conductors in series with the inhibit circuit in which either a plane inhibit conductor Z 1 , Z 2  ... Z p  or an individual R, L shunt impedance Dz 1 , Dz 2  ... Dz p  is connected in series in each plane, depending on the position of plane selection switches Sz 1 , Sz 2  ... Sz p . The position of switches Sw 1 , Sw 2  is reversed for reading, the inhibit circuit being then disconnected. Two current sources are used in Fig. 2 (not shown) each current source being operative in half the planes of the store. In a modification, Fig. 3, the shunt impedances are omitted, and the z conductors in a plane are divided into four sections Z 11  ... Z 14 , Z 21  ... Z 24 , Zp 1  .. Zp 4 , each set of four sections being connected to a respective group of switches Sz 11  ... Sz 13 , Sz 21 ... Sz 23  and Sz p1  ... Sz p3  so that any selected two out of four sections in each plane are always in series with the x and y conductors for writing. Fig. 4 shows a modification of Fig. 3 in which capacitive noise is reduced by the use of transformer couplings T R1 , T R2 , T R3  ... to the inhibit conductors of each plane and to the x and y conductors. Block V 1  shows the four inhibit winding sections Z 11 -Z 14  of a single plane and an optional shunt impedance Dz 1 , while block Kx shows the circuitry associated with an x conductor Xr, switches S 1 , S 2  and diode D 1r  being operative for writing in series with the inhibit circuit, the y conductors in block Ky and switch Ss. For reading the x and y conductors are energized in series though switch S L  and respective coupling transformers T R3 . Noise may be further reduced by replacing the transformers of Fig. 4 with series balance-unbalance transformers, Fig. 5 (not shown). A more extensive use of balance-unbalance transformers is disclosed in Fig. 6 in which groups of such transformers such as T Ra , T Rb , T Rc  are themselves coupled to a respective further balance-unbalance transformer T<SP>1</SP> Ra , T<SP>1</SP> Rb , T<SP>1</SP> Rc . Further noise reduction is possible by the use of balance-unbalance transformers of the type shown in Fig. 7.
