IPC: G06F19/00
Filed: 1970-05-13
Abstract: 1303288 Digital computer for a nuclear reactor EUROPEAN ATOMIC ENERGY COMMUNITY 13 May 1970 [20 May 1969] 23223/70 Heading G4A A digital computer is used for calculating the reactivity of a nuclear reactor in real time. A neutron flux counting tube 2 emits a series of digital pulses Py representing neutron flux which pass to m separate digital computer units 1, the outputs of which pass to a common line 3. A multiplexer 4 ensures that the signals on line 3 do not overlap and they are passed to a divider counter 6 with a source signal S where the sum of the outputs is divided by Py and finally passed to a counter 7. The apparatus solves the equation where # is a constant and Bi represents a series of constants. The computer unit (Fig. 2).-This employs operational digital techniques and comprises three parts. A multiplier 8, 9 multiplies the clock rate t 1  of the multiplexer 4 by a group constant #i, t 1  being fed to a forward counter 8 in binary and #i being set by flip-flops or permanent switches 9. AND circuits 10 effect the multiplication. The middle part solves this equation.  Py feeds a two-way counter 12 and the output of the multiplier 8, 9 feeds the counter 11. Another multiplier 14 multiplies Pi by a constant Bi. An alternative set-up to Fig. 2 is also described (Fig. 3, not shown).

Title: Variable speed and differential gearing
IPC: F16H33/10
Filed: 1923-09-17
Abstract: 204,062. Mauvillier, B. Sept. 16, 1922, [Convention date]. Variable-speed gearing is rendered automatic by gyratory action. A mass i, Fig. 1, is secured to a spindle d transversely mounted in bearings c in a driving-member a. A bevel pinion e fast on the spindle d meshes with a crown wheel f secured to a driven shaft g. As the mass i gathers speed owing to the pinion e rolling on the wheel f, it tends to keep its axis fixed so as to drive the wheel f in an elastic manner. The wheel f may be flattened, when the masses i' may be secured to the ends of the spindle. A mass e<3> may balance the pinion e. Two such gears may be combined to form a differential or balance gear. In a modification shown in Fig. 4, pairs of mutually-perpendicular planetary spindles d<1>, d<2> carried by a driving-element a carry masses i<1>, i<2>, and are connected by spiral gearing e<1>, f<1> and e<2>, f<2> to the driven shaft g.

Title: Improvements in or relating to manoeuvring and controlling mechanism for marine engines
IPC: F01L13/00
Filed: 1928-08-14
Abstract: 296,777. Maschinenfabrik Augsburg- Nurnberg Akt.-Ges. Sept. 9, 1927, [Convention date]. Mechanical telegraphs.-In mechanism for controlling or manoeuvring marine externalcombustion engines of the Diesel type, the engine-room telegraph is coupled with the engine controls so that movement of the telegraph effects directly the appropriate setting of the engine control means, and the engineer has always to turn a ha.ndwheel in the same direction. An order telegraph T is connected by a chain drive a to a cam b actuating a vertically sliding rod c which moves a reversing valve B into the desired position and at the same time sets a locking lever d'. The lever d<1> is pivoted at g to a lever d, and is also connected therewith by a spring coupling h. It carries locking abutments i<1>, i<2> separated by a gap k and co-operating with the ends l<1>, l<2> of an annular flange formed on a member mounted co-axially with a hand-wheel C. In response to an order on the telegraph the engineer turns the hand-wheel C in an anti-clockwise direction until the abutment i<1> engages the end l<1> of the flange. This partial rotation actuates a valve n by means of a cam m, thereby placing under pressure one or other of the oil reservoirs D according to the position of the reversing valve B actuated by the chain drive a. This oil pressure displaces a piston Q and so moves through the agency of a lever z, the engine control shaft G. Upward movement of a rod o. connected to the lever z, raises the levers d, d<1> and releases the interlock between members i<1>, l<1>, thereby allowing further rotation of the hand-wheel C. Such rotation closes the valve and by means of cams p, t successively actuates valves q. v for admitting air to the starting-valves of the cylinders and for supplying charging air to the cylinders. Upon further rotation of the hand-wheel, fuel is admitted to the engine by the actuation through a crank of a rod w associated with the fuel-pump. The cam p is automatically uncoupled from its shaft on further rotation of the hand-wheel, so as to permit the valve q to close, and subsequent rotation of the hand-wheel effects only a regulation of the fuel supply. The cam p may be actuated by a handlever F to admit air to the starting-valves.

Abstract: 1,263,922. Photographic silver halide processing compositions. KODAK Ltd. May 16, 1969 [May 17, 1968], No.23526/68. Heading G2C. A developed and stabilized image is formed in an imagewise exposed layer of a photographic silver halide material by treating the material with an aqueous alkaline solution containing a photographic silver halide developing agent and thiosulphate or thiocyanate silver halide stabilizing agent in the presence of an alkylene oxide compound. The material may be a photo-developable material. The developing agent may be a 3- pyrazolidone or have the formula: wherein X is 0 or an amino group, n is 0, 1, 2 or 3 and R is H or OH, R not being H when n is 0 (see British Patent 767, 700). The stabilizing agent is preferably an alkali metal thiocyanate. The aqueous alkaline solution preferably contains at least 70g per litre of sodium or potassium thiocyanate. The alkylene oxide preferably has the formula:- formula:- R-O(CH 2  CH 2  O) n H wherein R is H, alkyl, aryl or an aliphatic acyl group, and n is from S to 100. The aqueous alkaline solution containing the alkylene oxide compound can be applied before or after photodevelopment, but is preferably applied after the material has received a small uniform postexposure because such an exposure, whilst insufficient to make the latent image visible, intensifies the latent image and improves the final image quality (see Examples 1 and 4).

Abstract: 693,675. Magnetic measurements. BERTHOLD, R. Oct. 11, 1951 [April 5, 1949], No. 23707/51. Class 37. In an instrument for measuring the thickness of non-ferromagnetic films on a ferromagnetic base by the pull of a permanent bar magnet suspended on a spring, the magnet is fitted with a pole shoe of highly permeable non-retentive material. A permanent magnet 1 is fitted with a pole shoe 2 and is employed for measuring the thickness of a non-ferromagnetic layer on a ferromagnetic base 3. The magnet hangs from a balance beam and is pulled away from the layer by a spiral spring wound about the pivotal axis of the beam. The spring is tensioned by winding up the end not attached to the beam, the amount of winding measuring the pull of the magnet. The pole shoes 2 may be spherically curved at the end, as shown in Fig. 1. Alternative forms of shoe are shown in Figs. 2 and 3. For measuring thick layers both ends of the magnet are fitted with pole shoes as shown in Fig. 4, the magnet system being pivoted so that the measurement is not affected by uneven withdrawal of the magnet from the base. By means of a locking rest the spring tensioning means may be held in the position it has reached when the magnet pulls away from the test-piece. The notches of this rest may be unevenly spaced to correspond with the non-linear dependence of pull on thickness of film. Readily interchangeable permanent magnets of different strength may be provided for different ranges of measurement.
