Title: Improvements in or relating to multi-channel signalling systems
IPC: H04J1/14
Filed: 1944-03-07
Abstract: 575,213. Multiplex transmission. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and MURRAY, L. J. March 7, 1944, No. 4171. [Class 40 (iv)] In a carrier multiplex system, the supervisory signals associated with the various speech channels are transmitted at frequencies lying within the gaps between the speech channels, and the speech and signalling channels are defined by the use of band-pass filters of the crystal resonator type. In a 12-channel system using "go" and " return " pairs, the speech channels are first assembled as the lower side-bands of twelve carrier frequencies 64, 68 ... 108 kc. and these then modulate a group carrier of 120 kc., the lower side bands which lie within the range 12-60 kc. being selected for transmission. For a particular channel, the speech frequencies received over wires 10, 11 pass through the modulator 14, crystal band-pass filter 15, group modulator 20 and group low-pass filter 21, which need not be of crystal type to the " go '' pair 22, 23. Frequencies of 3.75 and 3.9 kc. are selected for signalling, and such frequencies received over wires 12, 13 modulate the same carrier as the corresponding speech wave in a separate modulator 16, and a narrow band crystal filter 17 selects the lower side bands which enter the group modulator 20 with the speech side band.

Title: Improvements relating to arrangements for use in measuring the liquid content of a container
Inventor: HANCOCK DEREK NORMAN ARCHIE
IPC: G01F23/296
Filed: 1961-03-07
Abstract: 997,481. Measuring by ultrasonics. BURNETT & ROLFE Ltd. June 4, 1962 [March 2, 1961], No. 4176/61. Heading H4D. The contents of a container, e.g. the depth of liquid in a vessel, is derived from the propagation time of sonic or ultrasonic waves which are directed upwardly through the bottom of the container and reflected at the upper surface of the content. As shown in Fig. 1, which is concerned with measuring the depth of a liquid 2 in a horizontal cylindrical vessel 1, pulses of ultrasonic wave energy produced by a transducer 4 (e.g. a piezo-electric crystal) under the control of a circuit 5 and directed upwardly from the bottom of the vessel are reflected at the upper surface 3 and returned via the transducer 4 and circuit 5 to an indicator device comprising a neon lamp 6 carried by a balanced arm 7 which rotates synchronously with the transmission of pulses the arrangement being such that as the lamp lights up on passing the zero mark of a circular scale 12 and lights up again when a reflected pulse is received. The neon lamp is covered by a mask 9 having a narrow radial slot 10 so that the scale which is calibrated in terms of depth may be read accurately. In an alternative arrangement, the lamp 6 may be stationary and the scale rotated so that the latter forms a stroboscopic disc. The lamp and scale may be replaced by a cathode-ray tube indicator for the transmitted and reflected pulses and in either arrangement the indication may given the volume or weight of the material in the container. When a plurality of containers are involved a single indicating device selectively connected to the different containers by suitable means may be employed. To avoid difficulties due to very short propagation times which arise when the level of the reflecting surface 3 is very low a minimum path length may be introduced by mounting the transducer 4 at the end of a tube 10, Fig. 3 (about two feet long) filled with a coupling liquid. The tube may be perpendicular to the position shown and a 45 degrees reflecting surface employed to direct the ultra-sonic waves vertically upwards (Fig. 4, not shown). For mounting the piezo-electric crystal the latter is rigidly held in a cup-like member 20 (Fig. 5) which is screwed into a ring 21 welded to the bottom of the container and a liquid tight seal provided by an 0-ring 22. A spacer ring 23 prevents the member 20 from being screwed in too far and the latter ring and ring 21 are provided with respective openings 25, 24 through which a coupling liquid may be introduced into the space 26. The assembly is completed by a further cup-like member 27 screwed around ring 21. It is stated that the device may be arranged to control the level of the contents of the vessel by controlling the opening of a supply line or a discharge passage.

Title: Improvements relating to control systems
IPC: H02P29/00
Filed: 1960-02-06
Abstract: 974,225. Automatic speed control systems. J. SAYERS. Feb. 6, 1961 [Feb. 6, 1960], No. 4272/60. Heading G3R. The speed control system for a motor vehicle, whereby an electrically controlled variable ratio transmission device is used to maintain constant engine speed (at any given throttle setting) described in Specification 927,394 is modified by replacing the amplidyne with a non-rotary amplifier for the controlling current. As shown, a pair of magnetic amplifiers M1, M2 are used. Their control windings L1, L2 carry a current whose direction depends on whether the voltage of an engine speed tacho-generator 20 is more or less than that of a battery Bl. The tacho-generator field F1 is energized from the battery according to the setting of a rheostat R2 connected to the throttle 15. The cores of M1 and M2 may thus be more or less saturated in one direction or the other and accordingly positive or negative half waves of a current from an A.C. source are regulated while the opposite half waves are suppressed. This current is applied to one of the windings 11 of the transmission device 10, which may be as described in the above mentioned Specification, a second winding 12 being energized from the battery through a rheostat R1 which, it is stated, may be used to effect reversal of the vehicle. The system is such that the current through winding 11 is automatically adjusted so that the resulting velocity ratio of the device 10 is that which enables the prevailing load to be driven by the engine running at its predetermined speed. In an alternative arrangement a pair of transistors replace the magnetic amplifiers for regulating the A.C. according to the tacho-generator voltage. In either case the A.C. source may be an engine driven alternator or a vibrator, or it may be switched D. C. from the battery. If an alternator, it may also be used for charging the battery and it may have an extra winding to replace the separate tacho-generator. The transmission device 10 may alternatively be an eddy current coupling or powdered iron clutch; these have only one control winding and since, then, the direction of current through it is immaterial only one magnetic amplifier or transistor is needed. Specifications 974,221 and 974,224 also are referred to.

Filed: 1963-02-01
Abstract: Acetates are prepared by reacting a monoolefine (2-4C) or an alkyl benzene at an elevated temperature with oxygen and acetic in the presence of a catalyst comprising, or consisting of palladium. The alkyl benzene is benzene substituted by one or two alkyl groups (1-4C) e.g. toluene, p-xylene or ethyl benzene.
