Abstract: 1,070,430. Account books. W. A. DOODY. Dec. 6, 1965 [Dec. 8, 1964; Oct. 7, 1965], No. 51705/65. Heading B6A. In an account book, the leaves 6 are hinged at 10 within the covers 1, 2 about an axis transverse to the lengthwise direction of the columns on the leaves, and a heading strip for the columns is provided at 7 on the cover 1, or a flyleaf, which is adapted to project beyond one edge of the leaves and extend transversely adjacent to the head of the columns when the book is opened flat. There may be two or more series of leaves, arranged side-by-side, on a common, hinge 10. The covers 1, 2 are hinged at 3, 4, respectively, to a spine 5, and the hinge 10 is arranged on the cover 2 just below the hinge 4; thus, with the book closed, the covers will not project substantially beyond the leaves 6, but with the book open, the cover 1 will extend at 7 beyond the leaves. The hinge for the leaves may coincide with the centre of the spine 5 (Figs. 1-3), and the two covers project beyond the leaves in the closed and open positions. The heading strip at 7 serves all the leaves, and the totals can be entered on a folded-over portion of the bottom of a leaf, and this portion can then be folded back, when the leaf is turned upwardly, to expose the totals. A leaf of perforated heading strips can be incorporated in the book. and this can be gummed.

Abstract: 1,214,088. Amines from N-substituted amides. ARMOUR INDUSTRIAL CHEMICAL CO. 1 Nov., 1968 [2 Nov., 1967], No. 51932/68. Heading C2C. Primary or secondary amines are prepared by reacting an N-substituted amide with ammonia to form the corresponding amine and an unsubstituted amide and dehydrating this amide to its corresponding nitrile to achieve separation of the amine from the amide. The N-substituted amide is preferably heated to 200-350 C. and reacted with NH 3  in a mole ratio of 2 : 1 to 70 : 1. Subsequently the unsubstituted amide formed may be carried in an NH 3 -stream through a catalyst such as bauxite to form a nitrile, e.g. at 200-350 C. Amongst numerous examples N-(tert-dodecyl) formamide is converted to N-(tert-dodecyl)amine, N,N- dioctyl acetamide to N,N-dioctylamine, macetotoluidide to toluidine and acetamidostearylamine to aminostearylamine.

Filed: 1966-03-08
Abstract: 1,146,612. Programmed control. GOSUDARSTVENNY PROEKTNY INSTITUT "ELEKTROPROEKT". March 8, 1966, No.52003/65. Heading G3N. A system for controlling the operation of a number of devices includes a selectively interconnected matrix, connecting input controlled units with output controlling units, and a feedback matrix; the output units comprising amplifiers operating with a time delay and the input units each incorporate time controlled sources whereby a voltage appears on one or another bus-bar of the selectively inter-connected matrix in the presence or absence of an input signal. As shown, the outputs of units 1-3, each having terminals 4, 5 to one of which signals are applied to control the unit, are connected to energize direct or inverse bus-bars 6, 7 which are selectively inter-connected to output bus-bars 10 through diodes 9 or 9'. The output bus-bars 10 are connected to matrix resistors 11 and via diodes 12 to terminals 13 which are selectively linked and inter-connected to output units 14, 15. The output units are connected through terminals 24, 25 to solenoids or servomotors to be controlled. The input units 1-3, the matrix resistors 11 and the output units 14, 15 are energized from a supply unit 17. The input units each comprise two sources of which one source, controlled by the input signal, is connected in series opposition to a source within the supply unit 17 and to the direct bus-bar 6 and the other source, also controlled by the input signal, is connected to the inverse bus-bar 7. The sources are controlled so that the existence of an input signal causes a signal on bus-bar 10 with a diode 9 and absence with a diode 9'. The converse occurs with the cessation of the input signal. The inter-connection of feedback bus-bars 26, 8, as at 10a, enables an output signal from unit 15 to be maintained, by feedback through the unit 2, on cessation of an input signal to unit 1. This storage function is cleared by feeding an input signal to unit 3 simultaneously with the cessation of the input signal to unit 1. The output signals are protected against temporary supply interruption by stores 16. The output units each comprise a pre-amplifier coupled through a resistance-capacity delay network to a final stage controlling the device. The time-delay is regulated by changing the valve of the resistor. It is stated that the amplifiers may incorporate transistors and thyristors. Signal instruments 27 indicate the state of the system.

A differential pressure transducer comprises two bellows inter-connected by a rod attached to the core of a differential transformer, or the cores of two separate transformers whose outputs are connected to a summing amplifier in opposition, the mechanical linkage being such that common changes due to pressure, temperature, acceleration, inclination &c. may be automatically neutralized. As shown Fig.1, sealed chambers 6, 7 each contains a bellows 12, 15 filled with oil 19, 20 and inter-connected by bores 21, 22 to a central recess 23 in a mounting plate 1, housing a differential transformer 31. The end-plates 13, 16 of the bellows are connected by rods 25, 24 to a lever 26 hinged at 27 about a rod attached to the core 29 of the transformer. The two pressures are introduced at 10, 9 to the chambers 6, 7 to produce a lateral displacement of the core and an output voltage from the opposed secondary windings of the transformer indicative of the pressure difference. Common changes in pressure and temperature cause movement of rods 24, 25 about hinge 27 with no movement of core 29. In modifications (a) the end-plates of the bellows, which are in line, are inter-connected by springs carrying the core, and pass through rubber stoppers at the entrance to the bores, preventing excessive pressure from damaging the bellows; (b) each pressure chamber has its own transformer, the outputs being subtracted electrically and fed through a square-root network, to determine the rate of flow of a fluid through a conduit; (c) the cores of the transformer are mounted pointing in the same direction, to eliminate the effects of shock, acceleration and variation in inclination; (d) mechanical damping is effected by restricting the size of the bores inter-connecting the bellows; (e) the bellows may alternatively be flat diaphragms.

Abstract: 1329594 Infra-red tracking apparatus HUGHES AIRCRAFT CO 13 Nov 1970 [18 Dec 1969] 54166/70 Heading H4D An infra-red target tracker including means for inhibiting the response thereof during a time interval including the occurrence of a flame from an associated gun, when the gun flame would traverse the detector field of view. In a first embodiment, Fig. 2, the tracker detector comprises infra-red sensors 20-30 defining coarse and fine tracking fields of view. If detectors 23 or 25 detect a gun flame and the tracker is operating in its fine track mode, AND gate 51 triggers a 1 ms. pulse from monostable 54 and a variable width pulse from monostable 52. The resetting of monostable 52 triggers a 10 ms. pulse from monostable 58 which is used to inhibit the tracker and an associated laser range finder. The monostable 58 output is integrated and the integral is sampled at the instant of a gun flame, the integral amplitude being used to set the width of the monostable 52 output so that the next gun flame occurs in the centre of the inhibit pulse. In a second embodiment (Fig. 4, not shown), a series of azimuth and elevation gun angles which would cause interference of the tracker, are stored in magnetic disc or drum stores and compared with the instantaneous values of required gun angles generated by the fire control computer. When these angles compare infavourably, the fire command signal from the fire control computer generates a 10 ms inhibit pulse for the tracker and range finder.
