Title: Rotor feed for an automatic firearm supplied by a single link hook and eye chain belt
IPC: F41A9/31
Filed: 1973-10-12
Abstract: 1440685 Ammunition feed for automatic firearms FRANCE ARMED FORCES MINISTER OF 12 Oct 1973 [13 Oct 1972] 47881/73 Heading F3C A shaft 4b, transverse to a feed passage 5, 6 serving for entry and exit of a single hook and eye linked cartridge belt, and in a central zone of the passages, has keyed thereto a starwheel rotor 4a which projects beyond a wall of the passage and which provides the drive for the belt links M1, M2, M3, so that in use successively each link when at the rotor has its cartridge removed by a pusher inserted in an opening 8 of the passage, a fixed cam 10 being provided in the central zone of the passage and associated with the wall for retaining a link against reaction movement when the associated cartridge is removed to avoid belt breakage. The cam 10 is supported on the shaft 4b and is held by contact with the wall; the cam extends only towards the passage 6 and in the same direction as the hook 2 of each link M1, M2, M3. The reason for this is that for right to left belt movement F2 cartridge removal occurs on the right hand side of the shaft 4b, the reaction aiding removal of the hook 2 of the associated link from the eye 3 of the adjacent link, whereas for opposite belt movement F2, reaction due to cartridge removal on the left hand side of the shaft 4b only aids retention of the eye 3 of the cartridge with the adjacent hook 2. A removable empty link guide 7 may be bolted in the passage 5, 6 on one side of the central zone according to the desired belt movement.

Title: Electrical signalling apparatus
IPC: G01S17/32
Filed: 1970-09-17
Abstract: 1281839 Measuring phase HEWLETTPACKARD CO 17 Sept 1970 [24 Nov 1969] 48922/70 Divided out of 1281838 Heading G1U In optical distance measuring equipment, a beam of amplitude modulated infrared light is alternately transmitted to a remote reflector and fed through a reference path, the light received back from the reflector having its modulation phase compared with the reference beam received at the end of the reference path. The transmitted and reference beams are in the form of within-pulse amplitude modulated pulses producing corresponding bursts of modulation signals in the equipment photodetectors. Continuous waves of the modulation signals, retaining the same respective phases are produced from the respective pulses for the phase comparison. The two continuous signals I3-4 and H3-4, Fig. 4 exhibiting the distance-dependent phase differences as shown, are fed, via Schmitt triggers 74, 72, to a bi-stable circuit 76 which produces a pulsed output, the pulses having widths equal to the phase difference. These are fed to a gate 82 to pass current from source 80 to integrating means 78 such that a current appears at the output of means 78 proportional to the phase difference. The relation between the phase difference # and the distance R is of the form R = N1. #1 + # 1 /2# À #1 = = n 2  (10#1) + #2/# . (10.#1) such that if the modulator wavelength # is initially made equal to 2 feet, the phase difference will give the fraction of a foot part of the distance and if the wavelength is then multiplied by ten, the phase difference will give the 0 to 10 part of the distance and so on. A function selector 99, Fig.2 thus successively steps up the modulators wavelength by ratios of ten by control' of the synthesizers 45 and local oscillator 53. Assuming that the shortest wavelength is being used, switch 101 is activated and is set in any one of ten positions to give corresponding increasing current values 0 to 9. These values are of opposite sign to the phase difference dependant output current and when to two currents are equal, zero reading appears on meter 90. Switch 101 is then stopped in its position to indicate the fractional foot part of the distance. Switches 103, 105, 107 are similarly successively set to give the units, tens and hundreds parts of the distance. Gate 86 and filter 88 recieve the signals H3-4 and I3-4 and produce the triangular response shown to the phase difference. The phase difference regions # = 0 degrees and # 360 degrees are inacurate. A level detector 92 therefore detects when the response is below a detection line indicating these regions and produces a current which drives the needle of meter 90 off scale. The positions 0, 1, 2 and 8, 9 for switches 101/107 also indicate that the inaccurate regions are near and a signal G3-4 is then produced which changes over switch 109 so that the signal H3-4 is phase shifted by 180 degrees. The phase difference also moves into the more accurate middle region.

Abstract: 1,094,488. Hydrostatic transmissions. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN. UND ARMATURENFABRIK KOMM.-GES.]. Nov. 26, 1965 [March 5, 1965], No. 50327/65. Heading F2D. A hydrostatic transmission for a vehicle includes a control valve 1 between the motor supply lines 24, 25 to provide the differential flows required, e.g. upon wheel slip or during turning. The valve comprises a piston element 2 centred by springs 3, 4, and includes chambers 10, 11 interconnected by a throttle passage 9, the valve displacement controlling communication between an internal pressure chamber 14 and external casing ports 12, 13. When the driving wheels 28, 29 rotate at the same speed valve member 2 is centred as shown and being completely open can compensate any slight differences of pressure in lines 24, 25. In the event of appreciable difference of wheel speed the pressure differential in lines 24, 25 is transmitted to chambers 10, 11 to displace valve member 2 against spring 3 or 4 until equilibrium is reached. A large pressure differential moves valve 2 sufficiently to cut off supply port 12 or 13 and thus prevent wheel spin. Tappets 4, 5 bearing against springs 3, 4 are connected to the steering linkage 19 to increase the spring loading during a sharp turn and thus prevent closure of valve 2. The arrangement may be duplicated for a four-wheel drive, Fig. 3 (not shown).

Title: Self-compensated amplifier circuit

Filed: 1972-11-01
Abstract: 1341799 Transistor amplifying and pulse circuits MOTOROLA Inc 1 Nov 1972 [15 Nov 1971] 50327/72 Heading H3T In a transistor amplifier the base is biased from a junction point between two resistors connected in series in the collector circuit: the arrangement comprises a compensation circuit for change in supply voltage. As applied to a timing circuit, transistor 13 Fig. 1 is normally cut-off, cutting off transistor 19, so that capacitor 30 is charged to the voltage of the supply 23. Upon a signal being applied to the base of transistor 13 it becomes conductive, whereupon transistor 19 becomes conductive, discharging capacitor 30: increase in discharge current, due to increase of the voltage at terminal 23 is compensated by decrease in the voltage, since the potential of point 26 is clamped by the base-emitter voltage of transistor 19, so that the potential of the collector of transistor 22 is decreased by increased current in resistor 20. As applied to an A.C. level detector, in which transistor 61 becomes conductive when the sum of the D.C. potential at its base and the peak A.C. applied thereto exceeds a predetermined value, the A.C. signal is applied to the base of transistor 47. Increase of the supply voltage at terminal 52 increases the gain of transistor 47 and hence the A.C. signal at the base of transistor 61; since the point 56 is clamped at the base-emitter voltage of the transistor 47, the collector D.C. potential of this transistor decreases and so compensates for the increase in A.C. signal. It is stated in the Specification that the arrangement may also be used as a compensation stage in directcoupled amplifiers.
