Filed: 1921-05-27
Abstract: 164,321. Kegresse, A. June 5, 1920, [Convention date]. Endless-track vehicles. - Endless tracks for vehicles are formed of a flexible belt of rubber and canvas, provided with a core of a vegetable cellular material such as compressed cork, paper, canvas, wood, or the like which is enclosed in several layers of canvas. In one construction, Figs. 1 and 2, the core is in the form of blocks 2 disposed in a central guiding and driving rib which is provided with transverse triangular openings 1, between the blocks. The bearing surfaces 3 for the supporting-rollers a are inclined and the tread surface comprises two continuous ribs 4 connected by transverse ribs 5. The ribs 4 may be reinforced by rolling the edge of the canvas insertion as at 6 or by a cable 1 of metal, hemp, or other material protected by canvas. In another construction, Figs. 6 and 7, intended for light vehicles, the blocks 2 are incorporated in the tread and the bearing surface is formed by a web connecting the block members, and may be flat or provided with a double inclined face as at 13. Extensions 14 may be provided at the sides of the tread to take the load when the tread sinks in soft ground.

Abstract: 628,553. Valve generating circuits; frequency modulation; automatic tuning correction. STANDARD TELEPHONES & CABLES, Ltd., and MENGEL, G. P. DE. May 16, 1946, No. 14810. [Classes 40 (v) and 40 (vi)] A valve oscillator comprises a two-terminal network having a negative conductance and a susceptance which is a function of an applied potential, the terminals being connected to an impedance which automatically controls the power dissipation. The circuit may be employed for automatic tuning correction or frequency modulation. The valve 1, Fig. 2, is arranged with a capacitor C<1> between the screen and suppressor grids and a resistor R<2> in the suppressor lead to present negative conductance to the left of the dotted line. The capacitor C<3> together with resistor element 24 determines the frequency of oscillation. in conjunction with the elements C<1>, R<2> and the conductance of the valve. By varying the grid bias, the frequency may be altered. The amplitude is stabilized by the use of a thermistor in the combination 24 and the screen grid is fed through the choke 16. In a modification, Fig. 3 (not shown), the valve 1 is replaced by a twostage negative feedback amplifier, the gain of which may be varied. The resistor R<2> and capacitor C<1> are interchanged and the impedance presented by capacitor C<3> is replaced by the leakage inductance of the output transformer of the amplifier. In a further modification, Fig. 5, a symmetrical arrangement is employed with the grids of valves V<1>, V<2> energized out of phase, the frequency determining components being capacitors C<2>, C<3> and resistors R<1>, 62 and 63. The conductance of the valves V<1>, V<2> may be varied by altering the grid bias and a thermistor 63 controls the power dissipation. Specifications 556,757 and 596,916 are referred to.

Title: Process for the manufacture of metal-ion exchanger resins capable of forming chelate complexes
Inventor: NAUMANN GUNTHER
IPC: B01J45/00
Filed: 1957-05-09
Abstract: Metal-ion exchangers capable of forming chelate complexes may be prepared by reacting a cross-linked resin obtained from 1-1,5 mols of m-phenylene diamine and 2 mols of formaldehyde, the resin being insoluble in water or in aqueous salt solutions, acids and alkalies, with mono-chloracetic acid or a salt, ester or other derivative thereof reacting in a similar manner.  1 mol of the chloracetic compound is used per -NH2 group in the diamine used to prepare the original resin; and when the ester is used, the product is hydrolysed to liberate the acid groups.  The resins are particularly selective for copper.  In Examples: (1) a resin is prepared from 0,5 mols of m-phenylene diamine dihydrochloride and 0,7-1,0 mol formaldehyde under acid conditions, is converted into the -OH form by treatment with 10% Na2CO3, and is heated with an aqueous solution of 1 p  mol of ClCH2 COO Na for 4 hours at 100-105 DEG C; (2) Similar to (1), but the original resin remains in the -Cl form and ClCH2COOH is used; (3) Similar to (2) but ClCH2COOEt was used; the product was then hydrolysed with 10% HCl or Na2CO3 for 3-6 hours.

Title: A process for the production from whale blood of blood meal suitable for use as a feeding stuff for animals
IPC: A23K10/24
Filed: 1936-05-26
Abstract: Blood meal suitable for use as a feeding stuff for animals is produced from whale blood by sucking the blood while still at body heat from the carcass during the cutting up, coagulating the blood in a continuous operation, separating the blood serum and working up the residues by drying to give a meal.  In an example, the carcass is laid on its back and the head and the throat and main arteries are removed together with the appendant viscera.  The blood which collects in the thorax is rapidly removed therefrom through a flexible pipe which is connected to a receiver which is under reduced pressure.  From the receiver the blood passes to an apparatus in which the blood coagulum is comminuted and the partially coagulated blood reduced to a homogeneous liquid which is passed to apparatus in which it is treated with a coagulant, e.g. hot water which may be fed in laterally at the bottom to impart a vortex movement to the blood. The coagulation may be effected at 75 DEG  C.  The serum is separated from the product by filtering or pressing and the solid residues are dried and worked up into a meal.

Abstract: 402,782. Screw propellers. GILL, J. H. W., 33, Earl's Court Gardens, London. May 30, 1932, No. 15337. [Class 114.] In screw rotors, such as propellers, pumps and turbines, the pitch at the working edge of each blade varies radially so that the product of the pitch multiplied by the radius either has a minimum value at a position whose radial distance from the axis is not greater than the normal design mid-blade radius and increases from such value both inwards toward the boss and outward toward the blade tip, or in the limiting case is constant at all radii. Also the width of each blade either decreases radially both inwards and outwards from a maximum value at a radial position not greater than the normal mid-blade radius, or is constant at all radii. The six-bladed rotor A has its blades carried by a boss B of radius approximately .43 of the tip radius. The pitch at the working edge C is given by a curve D of which the abscissµ are radial distances. The curve E on the same basis indicates the width of the blade. The surfaces containing the leading and following edges H, C are preferably symmetrically disposed in respect to the central line and the thickest portion of the section is indicated by chain lines J, representing such thickness.

Abstract: 678,000. Machine gun cartridge feed. BREVETS AERO-MECANIQUES SOC. ANON. June 9, 1949. [June 19, 1948] No. 15413/49. Class 92 (ii). Relates to cartridge-belt feed mechanism of the type in which the belt is fed, a distance equal to the pitch of the cartridges, in two steps by a sliding breech block, the first step during the recoil stroke of the block and the second during its forward movement. According to the invention, the first step is effected only during the latter part of the recoil stroke. The invention is shown applied to an automatic gun in which the breech block 5 reciprocates in a barrel-extension 3, the oppositely-moving parts 9, 10 of the belt-feed slide carrying the step-by-step actuating pawls 11, 12 respectively being operated by a roller 22 on the breech block engaging a cam member 17 pivoted at 18 to the barrel extension 3. The cam member operates, through a slide 21 and pin 20, a lever 13 pivoted at its rear end to the hinged cover 7, Fig. 3, which also carries the parts 9, 10 of the belt feed slide. The front slotted end of the lever 13 engages directly with the part 10 and indirectly through a reversing lever 15 with the part 9. During recoil, and after an idle movement to the right of pin 22, the cam part 17a of member 17 (see Part II, Fig. 5) becomes effective to move a cartridge 2 shown in waiting position, to a central loadingposition, and during the return movement of the breech block this cartridge (see Part IV, Fig. 5) is loaded into the gun chamber, the cam part 17b being then effective to bring a second cartridge to waiting position. The breech block roller 22 is shown in Fig. 3 with an auxiliary roller 23 engaging a rail 24 on the barrel-extension to take up side strain as the lever 17 is engaged. This auxiliary roller arrangement, with modifications thereof, form the subject-matter of divided Specification 678,078.
