Title: An optical instrument for aiming direct-firing firearms
IPC: F41G3/32
Filed: 1955-12-29
Abstract: 791,566. Aiming devices for ordnance and smallarms. COEYTAUX, G., DERAMOND M., and HUGUES, E. Dec. 29, 1955 [Dec. 29, 1954], No. 37194/55. Classes 92 and 119. [Also in Group XX] A coincidence rangefinder having two spaced objectives of different focal lengths, coincidence of the images of a target being effected by rotation of the instrument about an axis perpendicular to the ranging plane, is mounted substantially vertically on a firing weapon to act as a sight, the focal length of at least one of the objectives varying with the target distance in such a way that rotation of the weapon and sight about a horizontal axis to effect coincidence of the images of the target gives the weapon the appropriate elevation for firing. Fig. 7 shows the rangefinder 7 mounted on the barrel of a rocket - launcher by means of a wedge 12 to set the sight and weapon for a target at a standard distance. The theoretical basis of the invention is described in the Specification Fig. 3 shows in elevation and Fig. 4 in plan the optical system of the rangefinder sight. The beam 1 from the target incident on the window F 1  of the sight is reflected by a prism P 1  to the entrance-pupil diaphragm D 1  of an objective O 1  whence it passes via the objective O 1 , Amici prism P 2  and rhombohedral prism P 3  to form an image adjacent a doublet O 2  having a strongly curved cemented surface and which is designed according to ballistic curve of the weapon to give the desired variation of focal length of the objective system O 1  O 2  with target distance. Numerical data are given for one such system. Light from this image reaches the eyepiece O c  through an aperture 6 in reflecting surface 5 between prisms P and P 4 . The other target beam 2, incidence on the window F 21 , passes the second objective O 21  and is reflected by prisms P 21 , P and surface 5 to form an image in th'e eyepiece O c  which surrounds the image formed by the other objective so that coincidence of the images may be readily observed. A scale indicating the range may be formed on the reflecting surface 5.

Title: Charging device for shaft furnaces
IPC: C21B7/18
Filed: 1975-09-10
Abstract: 1466504 Charging of shaft furnaces S A DES ANCIENS ETABS PAUL WORTH 10 Sept 1975 [20 Sept 1974] 37197/75 Heading F4B Apparatus for charging a shaft furnace includes a spout 2 that can be universally moved about a chute 3 to direct charge material to any desired point on the surface of the furnace. Three identical control elements comprising hydraulic jacks 16, 18 and 20 with connecting rods 22, 24 and 26 are spaced 120 degrees apart around the chute 3 and are connected to the spout by universal fastening elements 28. The jacks are universally articulated in the upper wall of the furnace by ball joints 54 and each jack is governed by a separate control and regulating circuit 60 so as to cause the jacks to reciprocate in such a way that the end of spout 2 describes a circle about the axis of the furnace. The circuits 60 include variable resistors R1 operated by cams 64, 66 and 68 which are positioned 120 degrees apart on a shaft 62 that is driven by a motor 61. The circuits are designed so that an alteration in the speed of motor 61 alters the amplitude of movement of the hydraulic jacks and hence the radius of the circle described by the end of spout 2. In addition supply of hydraulic fluid to the control circuits 60 is made via a regulating valve 80. Adjustment of this valve will also alter the amplitude of jack movement and in addition the speed of jack movement. Hence by adjustment of motor 61 and valve 80 the spout can be made to move in concentric circles of different radii or in spiral trajectory and so charge the furnace in any desired pattern. Other electrohydraulic control circuits including the use of bi-stable flip-flops (254), Fig. 1c (not shown), with two levels of output may be used. In further embodiments of the invention chains (90), Fig. 2 (not shown), may be used to connect the hydraulic jacks to the spout or the jacks may be used to operate crank arms (106), Fig. 3 (not shown), which are then attached by the arms (108) to the spout. In another arrangement two sets of gear trains driven by separate motors Fig. 4 (not shown), are used in place of hydraulic jacks to control the operation of the spout. A chamber 30 may be arranged in the upper part of the furnace fed with cooling and cleaning gas from a pipe 36, to protect the charging mechanism from adverse conditions.

Title: Method for continuous self-sustaining flameless oxidation of combustible materials
Inventor: ZIMMERMANN FREDERICK JOHN
IPC: C02F11/08
Filed: 1955-12-30
Abstract: A process for continuously oxidising combustible materials dispersed in liquid water comprises passing the dispersion and an oxygen-containing gas into a reaction zone under super-atmospheric pressure and maintaining conditions in the reaction zone such that the combustion products are produced at a rate which balances stoichiometrically the rate at which the combustible materials and oxygen-containing gas are fed to the reaction zone.  A flameless oxidation reaction is established in the reaction zone and some of the water therein always remains in the liquid phase.  Preferably heat is initially applied from an external source to establish the reaction, after which such heating is discontinued. Specification 706,686 is referred to, and two examples closely similar to those described therein are given.  In another example, charcoal suspended in water is fed continuously at a rate of ten grams every thirty minutes together with air containing sufficient oxygen theoretically to convert ten grams of charcoal to carbon dioxide every thirty minutes, to a reactor containing 200 grams of charcoal and 1 litre of water, and maintained at 250 DEG C. and 800 lbs. per square inch pressure, the liquid level being maintained constant by heating or cooling.  After one hour 20 grams of charcoal had been completely oxidised and vented from the reactor as carbon dioxide.  In a further example the amount of combustible material maintained in the reactor is approximately forty times the amount of combustible material in the liquor fed per hour to the reactor.  To illustrate the treatment of material containing both combustible and non-combustible substances, in another example a gallon of "semi-chemical" liquor containing 4,44 pounds of sodium lignin sulphonate, sodium acetate, sodium sulphite and carbohydrates and the like, is fed into a reactor maintained at 250 DEG C. and 800 lbs. per square inch, and further supplies are then introduced continuously together with air containing the oxygen theoretically required to oxidize completely all the combustible materials in the feed, so as to maintain within the reactor an amount of combustible material having the same oxygen demand as the original reactor charge after equilibrium conditions are established.  Energy is generated by the reaction, and the reaction products are nitrogen, water vapour, carbon dioxide and sodium sulphate, the latter being removable as ash or solution.

Abstract: 1394630 Program control of knitting machines BILLI SpA 8 Aug 1973 [12 Aug 1972] 37560/73 Heading G3N A plurality of circular knitting machines, each having a rotating needle cylinder with an associated angular position detector and revolution counter, are controlled by a central unit holding a single program. The unit is connected cyclically through a switching arrangement to each machine in turn and transmits control signals in response to the instantaneous position and revolution count of the respective cylinder. As shown, each of n knitting machines has a needle cylinder 7 driven by a motor 3, and a number of actuators 9 1  ... 9 y , operated by pulses from central control unit 1. A Gray-coded drum 131 rotates with the cylinder 7 to produce discrete angular position signals fed to the control unit 1 on lines 23. Each complete revolution produces a pulse on a line 35 connected to a revolution  counter 15 which supplies signals to unit 1 on lines 27, and also produces an input to a unit 17 which is preset to enable each machine to produce an article of a different desired size by means of additional cylinder revolutions not counted by the main counter 15. A cyclical switching generator 19 uses an HF oscillator 197, square pulse former 199, binary counter 191 and decoder 193 to operate cyclical NAND logic switches 21, 25, 29 at a frequency such that each machine is connected to the control unit 1 at least once for each of the discrete angular positions of its needle cylinder. The unit 1 includes NAND gates 601 which provide, in response to inputs from the switches 21, 25, control signals which are transmitted over lines 101 and through switch 29 to the actuators and cylinder of the appropriate machine.
