Title: Remote-controlled alarm networks
IPC: G08B25/14
Filed: 1965-11-25
Abstract: 1,120,455. Alarm systems. GROUPEMENT ATOMIQUE ALSACIENNE ATLANTIQUE. 25 Nov., 1965 [26 Nov., 1964], No. 50144/65. Heading G4H. Each of a number of remote stations 1, e.g. alarm posts or monitored premises is connected over a two-wire line 2 to a corresponding printed circuit line card 3. Each card 3 has a pair of level detectors, Fig. 2 (not shown), which respectively provide an output when the holding current in the associated line 2 falls below or rises above the normal value in response to a call or a fault. When such an output is produced, a lamp corresponding to the calling station 1 is lit on panel 5 and an audible alarm 6 is actuated. The operator, through a control panel 12 and selector 7, then connects the calling station 1 with a printed circuit measuring card 9 and establishes an audio communication link 16, 17 between the central station and the calling station 1. The measuring: card 9, Fig. 5 (not shown), comprises an impedance matching amplifier and a chopper feeding a set of threshold devices, e.g. tunnel diodes, Fig.6 (not shown), one of which operates to light a corresponding display on a panel 11 to identify the type of call or fault. The type of call may be recorded on a magnetic tape or drum.

Title: Method of separating components of oleaginous mixtures by fractional crystallization
IPC: C11B7/00
Filed: 1965-11-25
Abstract: A process for separating components of an oleaginous material by fractional crystallization comprises the steps of lowering the temperature of the material to a temperature at which crystalline centres of crystallization of certain components are formed, subjecting said material to crystal-shearing agitation so that the crystalline centres are shattered and multiplied and dispersing the shattered centres throughout the material and allowing crystallization of the components desired to be separated to take place on the shattered centres as nuclei, and separating the crystals formed.  The process is described with reference to the winterization of summer oils, i.e. the removal of stearine from oils such as animal oil, fish oil, coconut oil, corn oil, cottonseed oil, soybean oil, olive oil, linseed oil and peanut oil.  The oil is preferably made into a miscella with n-hexane or other hydrocarbon, aldehyde or ketone, cooled in two stages, subjected to agitation in a blender, high shear mixer, homogenizer or sonic or ultrasonic vibrating device to multiply and disperse the crystal nuclei, allowed to crystallize and finally centrifuged to separate the solid precipitate. A part of this solid may be recycled to provide additional nuclei for crystallization.

In an hydraulic system with a double-acting piston a flow-control valve links the head and rod ends of the cylinder to permit rapid advance of the piston (due to differential piston area). The system is stated to be applicable to e.g. a power press or railway vehicle brakes. As shown in a BRAKE SYSTEM, Fig. 2, pump P supplies the cylinder through highpressure line H1 and low-pressure line H2; with the brakes off L.P. line H2 applies e.g. 180 p.s.i. to retract the piston and line H1 drains at about 30 p.s.i. to tank via relief valve 35 (detailed in Fig. 3, not shown). To actuate the brakes, magnet valve 40 (detailed in Fig. 4, not shown) is energized to close the drain via line H4 so that pressure builds up in line H3 to close relief valve 35. When pressure in lines H1, H6 reaches say 175 p.s.i. the piston in valve 44 (detailed in Fig. 6, not shown) opens the valve to connect lines H1, H2 and piston 43 rapidly applies the brake. As pressure continues to rise low pressure relief valve 36 opens at say 200 p.s.i. allowing valve 44 to close. AUTOMATIC TRAIN BRAKE CONTROL SYSTEM, Fig. 7.-The vent valve 40 has variable energization in this case and acts as a variable constriction to vary the pressure in H1 correspondingly. As shown the actual braking torque is measured by a transducer attached to a link connected to the brake shoe, the amplified braking-torque signal Q is compared with the required braking signal P in a summation network S, and the error signal P<SP>1</SP> is applied to the magnet valve. The TORQUE TRANSDUCER may be a strain gauge or semi-conductor load-cell, or a differential transformer (detailed in Fig. 1B, not shown) mounted between a blade-spring (19) and a link (17) connected to the brake shoe.
