Abstract: 898,632. Simulated instruments for aircraft flight trainers. ACF INDUSTRIES Inc. Dec. 24, 1959, No. 43844/59. Class 4. A simulated ball-bank indicating instrument for use in an aircraft flight trainer comprises a pair of autosyns 1 and 2 with concentric shafts 11 and 12 driven in response to electrical signals received from computing equipment (not shown). The autosyns are supported by a frame comprising plates 30, 32 and 34 clamped by bolts and spacers 36. Shaft 11 drives a gear 8 and a rotatable member 5 which, at a point adjacent its periphery carries a pivot pin 18. Shaft 12 drives a gear 13 and gears 8 and 13 mesh respectively with toothed sectors 7 and 19 formed in. arms 40 and 42 both mounted at their lower ends on a common pivot supported by plate 34 and a bracket 15. Pivot pin 18 is bored diametrally for the free passage of a rod 10 mounted at its upper end on a pivot 9 secured to arm 40, the lower end of the rod being of U-shape to support a disc 14 simulating a conventional ball. A curved lenssection transparent window 4 is mounted in the instrument in front of the simulated ball, the arc of the window having its centre outside the case of the instrument. Arm 42 carries at its upper end a shaped pointer 20 which simulates the conventional turning rate needle. In operation; energizatida of autosyn 2 drives pointer 20 through gear 13 and sector 19 and energization of autosyn 1 causes gear 8 and member 5 to rotate through approximately 90 degrees and, through sector 7, arm 40 will be driven through approximately 13 degrees. Rod 10 will thereby be caused to rotate about pivot 9 and slide through the bore in pin 18 to cause disc 14 to follow an arcuate path behind window 14 and simulate a conventional ball-bank display.

The acid halide is formed by reacting the corresponding acid (where OR in (I) is OH) with a halogenating agent, such as thionyl chloride. A compound where R in Formula I is a C 2-6  alkanoyloxyalkylamino radical can be obtained by treating an N - (hydroxyalkyl)(3 - trifluoromethylphenoxy)(4-halophenyl) acetamide with a suitable acylating agent, such as an alkanoyl halide. Compounds in which R is a di - (C 1-5  - alkyl)- amino - (C 1-5  alkyl) radical can be obtained by reacting the corresponding (3-trifluoromethylphenoxy)(4 - halophenyl) acetic acid with an appropriate di-(C 1-5  alkyl)amino- (C 1-5  alkyl) halide. 4-Halophenylacetic acid is obtained by treating a 4-halophenylacetonitrile with an aqueous solution of a base, followed by a strong acid. The acid is reacted with thionyl chloride and brominated and esterified with a lower alkanol to yield the (4-halophenyl) bromoacetate. Pharmaceutical compositions, having good hypocholesterolemic and hypolipemic activity, comprise a compound of Formula I (where R is other than halogen) with an inert non-toxic carrier, diluent or coating, in forms suitable for oral administration or intravenous injection.

Title: Production of electrolytic capacitors

Filed: 1974-10-11
Abstract: 1465290 Electrolytic capacitors SIEMENS AG 11 Oct 1974 [5 Dec 1973] 44092/74 Heading H1M In a method of manufacturing electrolytic capacitors, secondary formation is carried out in n successive stages by subjecting the capcitors individually to a forming voltage which increases in each stage, a constant current being employed in each stage of such magnitude that the forming voltage for that stage is reached in at most 20 seconds. The capacitor may comprise anode foil strips cut from an anodized sheet of valve metal, e.g. aluminium, wound into a roll with cathode foil and a paper separator impregnated with electrolyte. A constant current may be used throughout the secondary formation stages, the voltage difference between successive stages being made successively smaller. Alternatively constant voltage differences may be employed in which case either the constant current for each stage is adjusted or the formation time is increased, or the forming operation is carried out more than once per stage. Secondary formation is preferably carried out on unencased or unsealed capacitors. The capacitors may subsequently be aged at e.g. 85‹ C. for 0À5 to 2 hours at a voltage no greater than the maximum secondary formation voltage.

Title: Improvements in or relating to radio receiving apparatus for signals transmitted by pulse position modulation
IPC: H04B14/02
Filed: 1964-11-04
Abstract: 1,068,862. Pulse modulation systems; transistor gating circuits. PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd. Nov. 4, 1964 [Nov. 6, 1963]; No. 44950/64. Headings H3T and H4L. In a random access discrete address system of the type described in Specification 1,068,861, in which modulated pulses consisting of combinations of pulses of radio-frequency oscillations in the same wideband channel are transmitted, and each receiving station includes a gate which is released at the time intervals at which a modulated pulse destined for it is expected, the receiver comprises a normally cut off memory circuit for the demodulated signals which is released for a short period after the reception of a pulse, and a detector device which prevents the release of the output circuit when more than one pulse falls within the release period of the receiver. The arrangement reduces distortion due to interference. The received position-modulated pulses are detected at 2, Fig. 1, and supplied via gate 3, limiter 4 and amplifier 5 to a pulse position demodulator 6 provided, in known manner, with a sawtooth reference signal from a generator 7. The output of the amplifier 5 is also supplied via a delay line 8 and gate 9 to one input of a normally cut off memory circuit T which receives the demodulated signal from 6 as its other input. A detector D is also supplied by the amplifier 5 and is arranged to supply a signal via a threshold device 14 and amplifier 15 to block the gate 9 only if more than one pulse falls within the release period of the gate 3. Thus, if a single pulse occurs during this period it is demodulated at 6 and after a delay due to the delay line 8 a control signal is passed via gate 9 to enable the demodulated signal stored at T to be passed to the output BF and if more than one pulse occurs the gate 9 is blocked and no signal will be applied to the output BF. Transistor gated memory circuit.-The output e1 from the demodulator 6 charges a capacitor 19, Fig. 2 (not shown) the opposite conductivity transistors 17, 18 which are biased to be cut off supplying no signal to the output BF under these conditions. When a delayed pulse e2 from the gate 9 is supplied to the transformer 16 the resulting signals of opposite polarity release the transistors and the capacitor 20 is charged in proportion to the input el. If no pulse e2 appears the capacitor 20 will maintain its previous voltage level.
