Title: Improvements in or relating to endless track vehicles
IPC: B62D55/10
Filed: 1933-11-16
Abstract: 412,839. Endless - track vehicles. KEGRESSE, A., 156, Rue Armand Silvestre, Courbevoie, France. Nov. 16, 1933, Nos. 32013 and 32014. Convention dates, Nov. 17, 1932 and Oct. 30, 1932. [Class 79 (i).] Means actuated by the motive power of an endless-track vehicle for varying the distribution of the load on the tracks is controlled by the steering-gear. Thus, when the steering-gear is operated the load on the track on the inside of the curve may be borne mainly on the central part of the track so that the ends of this track are clear of the ground and do not scrape sidewise in making the turn. In the construction shown in Figs. 2 and 3, the steering lever 12, when moved from the straight-ahead position shown, opens one of two valves 7, 8 and admits compressed air or water from a reservoir 6 to a cylinder 18 arranged at the centre of the corresponding track so that a piston or diaphragm 17 is acted upon, this piston being fixed to a guide rod 16 pivoted to an equalizing beam 14 having a pair of rollers 13 running on the centre of the track. The load on the centre rollers is thus increased and that on the end rollers diminished or neutralized. A suspension spring 21 is provided in the cylinder 18 which is fixed to the vehicle frame. The fluid pressure may act to raise the end rollers instead of depressing the central rollers, or the central rollers on both sides may be depressed simultaneously. Electrical, mechanical, or electro-mechanical means may be employed instead of fluid pressure. In the mechanical method an engine-driven clutch controlled by the steering-gear drives a transverse shaft which acts on the load-bearing rollers through toggle linkages. The clutch may also be controlled by hand independently of the steering-gear.

Title: Manufacture of artificial masses
IPC: C08G12/08
Filed: 1929-10-23
Abstract: An aromatic amine is condensed, in the presence of an acid, with at most an equimolecular proportion of formaldehyde or agent yielding formaldehyde, whereafter the acid is eliminated and the fusible resin so obtained is dried, treated with a further quantity of aldehyde or agent yielding aldehyde, and compressed in a comminuted condition, whereby infusible products are obtained. A filler, a colouring material, or an agent imparting elasticity may be added to the fusible product before it is hardened.  The comminuted fusible resin may be applied to fabric, paper or other surface and hardened in the presence of an aldehyde, or agent yielding aldehyde, by compression, preferably at a raised temperature.  In an example, equimolecular proportions of aniline, formaldehyde, and hydrochloric acid are condensed at 35-40 DEG  C., and the condensation product is precipitated by addition of sodium hydroxide, filtered, washed and dried.  It is then hardened by mixing with a little paraformaldehyde or hexamethylenetetramine and heating under pressure.  Another example in which less acid is used is given also.  The products may be used for making horns for loud speakers, and other acoustic appliances.  Various other uses of the products are mentioned.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of aldehydes generally in the initial condensation.  This subject-matter does not appear in the Specification as accepted.

Abstract: 866,644. Nuclear reactor control rods. HAWKER SIDDELEY NUCLEAR POWER CO. Ltd. Oct. 6, 1959 [Oct. 9, 1958], No. 32234/58. Class 39(4). A control device in a nuclear reactor comprises material of high neutron absorption which is liquid during operation of the reactor and is contained in a reservoir connected to a channel of relatively narrow cross-section so that a rise in temperature causes an increase in the quantity of material in the channel and a resultant increase in the surface to volume ratio of the material. One form of device, Fig. 1 (not shown), resembles a thermometer and comprises a spherical stainless steel container joined to a capillary tube and filled with mercury. If the temperature of the reactor rises, the mercury rises up the capillary tube and reduces the reactivity of the reactor. The device may be designed for continuous operation or for emergency operation, in which case the mercury would be wholly within the container until a predetermined temperature is reached. A constriction may be provided in the capillary tube to prevent the mercury returning to the container after operation. In another arrangement, Fig. 2, an annular reservoir 4 is connected at its base to an inner annular channel 6. of relatively narrow cross-section and contains a liquid material 8 of low neutron absorption, which is employed to urge the neutron absorbent material 9 into the channel 6 when a rise in temperature occurs. The neutron absorbent material need not be mercury but may be cadmium.
