Abstract: 454,781. Endless - chain conveyers. EICKHOFF, A., (trading as EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI, GEB.), 176, Hunscheidtstrasse, Bochum, Germany. May 18, 1936, Nos. 14052, 14053, and 14054. Convention dates, Aug. 10, 1935, Dec. 27, 1935, and Jan. 20, 1936. [Class 78 (i)] In a conveyer of the kind in which pushplates are attached at each end to the links of oval link chains, each member, or pair of members, attaching a link to a push-plate is detachable from the push-plate. In one construction the attaching members c, Fig. 1, comprise a pair of fingers having flat eyes cl and broad strap sections c<2>. The eyes bear against the push-plate and are secured thereto by bolts d. The straps extend across the links a and are connected by bolts g. Projections f prevent the links from slipping between the fingers. When the push-plates and chain links are intended to assume a relatively inclined position, each finger may be provided with a projection h, Fig. 3, or a sleeve may be placed on the bolt g, to permit the necessary play. Each driving sprocket m, Fig. 5, is provided with passages n for the escape of foreign matter below the groove k receiving the upright links a'. When the push-plates are set obliquely with respect to the trough, the material can be discharged laterally by constructing the walls o, Fig. 9, so that sections can be removed or turned down. The obliquity of the push-plates may be obtained by passing one chain below and above a pair of guide discs arranged with their axes horizontal, or by relative displacement of the driving sprockets. In the latter case increased obliquity on the lower run is obtained by guide discs p<1>, q<1>, Fig. 11. The relative displacement of the sprockets can be obtained by mounting one sprocket free on its shaft and mounting on one of its faces a worm which engages a worm wheel fast on the shaft. By turning the worm the sprocket can be adjusted as desired. In a modification each sprocket is attached rigidly to a gear with oblique teeth which is driven from a corresponding gear on a lay shaft. One, or each, of the gears on the lay shaft is displaceable longitudinally by adjusting mechanism.

Abstract: 239,463. Saoutchik, J. June 2. 1925. Sliding-window opening and closing apparatus; vehicle windows.-For raising and lowering window members, particularly the rear windows of all-weather cars and like vehicles, two adjacent frame members are adapted to slide together when operated by transmission gear so that one window member moves at about twice the speed of the other until, when the movable members are in the closed position, they are slightly overlapping mid-way of the height of the window. The mechanism for operating a pair of sliding windows is shown in Figs. 4 and 5. The windows overlap at A, B when in the closed position, as shown in Fig. 6. The panes are carried by side bars 4, 5 movable in guides 2, and they are operable by a hand-operated cross shaft 8 which gears through pinions 9 with racks 11 on the member 4. On the upper ends of the members 4 are pinions 12 which gear with stationary racks on the window framing, and these pinions are in gear with racks 14 on the members 5. As the window frame is moved upwardly, the pinions 12 are rotated by engagement with the stationary racks and the window members 5 are thus lifted at a quicker rate until the position shown in Fig. 6 is reached. The parts are locked at the required height by a rotary locking member (not shown). The recess in which the sliding windows are housed in the vehicle body is closed by a narrow lid 17 hinged at 18, as shown in Fig. 8.

Abstract: 569,698. Fire-extinguishing. PYRENE CO., Ltd., and RATZER, A. F. Sept. 2, 1943, No. 14381. [Class 47 (ii)] Fire-extinguishing-air foam at pressures suitable for delivery through a considerable length of pipe system or fire hose, through a riser pipe on the side of an oil tank, or into the bottom of an oil tank against the pressure of oil in it, is prepared by delivering water, or a preformed solution of foam stabilising compound in water, at a pressure of at least 100 Ibs. per square inch, to jet orifices 7 to form two or more substantially parallel jets discharging into an unobstructed open end of a parallel sided or slightly flaring tube 2 into which air is entrained through openings 10 and 11 in the tube and an outer casing 1 respectively. Turbulence is imparted to the water by roughening the jet orifices 7, or by inserting a baffle plate 8 in the path of the water entering the orifices 7, to cause the jets to scatter at their fringes and occupy the whole of the crosssection of the tube 2 without intersecting one another. Where water is used, foam stabilising . compound is entrained in liquid form into the tube 2. The orifices may be from # inch to ¢ inch in diameter, and the ratio of areas of cross-section of the tube 2 and of jets at entry to the tube may vary between 5 and 15, and is preferably between 8 and 12. The length of the tube 2 should be not less than 4 nor more than 12 times the diameter. A flaring tube or chamber 5, or a delivery nozzle or hose is connected to the discharge end of the tube 2. Instead of the arrangement shown for entraining air, the end of the tube 2 may be supported at a distance from the jet orifices 7. Specifications 403,291 and 568,658 are referred to.

Title: Triorganosilyl amino acids
IPC: C07F7/08
Filed: 1955-05-20
Abstract: The invention comprises compounds of the formula R3Si(CH2)nCHNH2COOH in which R is a monovalent hydrocarbon radical and n is an integer other than 2.  The hydrocarbon radical may be alkyl, alkenyl, saturated or unsaturated cyclo-aliphatic, aryl or alkaryl.  When n is 1, the compounds may be prepare by reacting the half ester potassium salt of an ethyl triorganosilylmethyl malonate with hydrazine, treating the resulting hydrazide salt with nitrous acid to give the azide acid which decomposes spontaneously to an isatoic anhydride which is converted by conc. hydrochloric acid to the amino acid hydrochloride from which the free amino acid is obtained by treatment with silver oxide or with pyridine in methanol.  When n is 3 or more, a trihydrocarbonylhaloalkylsilane is coupled with malonic ester and sodium to give the malonic ester derivative which is hydrolysed with alkali to give a triorganosilyl substituted malonic acid.  This is brominated to give the alpha-bromo acid which is decarboxylated by heating to 140 DEG  C. or above and then treated with ammonium hydroxide to give the amino acid.  In the examples: (1) 2-amino-3-trimethylsilylpropionic acid (Me3SiCH2CHNH2COOH) is prepared starting from ethyl trimethylsilylmethyl malonate.  The following intermediates were isolated: potassium ethyl trimethylsilylmethyl malonate, and its hydrazide, the isatoic anhydride and the amino acid hydrochloride.  (2) 2-amino-5-trimethylsilylvaleric acid (Me3SiCH2CH2CH2CH NH2COOH) is prepared starting from gammabromopropyltrimethylsilane, sodium, ethyl malonate and ethanol.  As intermediates there are specified ethyl gamma-trimethylsilylpropyl malonate and alpha-bromotrimethylsilylvaleric acid. (3) The acid <FORM:0769180/IV(a)/1> CHNH2COOH is obtained as in (2).
