Title: Improvements in reamers or cutters for use in boring bars or like holders
IPC: B23B29/034
Filed: 1940-02-03
Abstract: 536,156. Boring bars and heads; reamers &c. TAYLOR, L. Feb. 3, 1940, No. 2154. [Class 83 (iii)] A reamer or boring-bar comprises a pair of cutters t adapted to be mounted to a slot or channel of a bar a and supported on an intermediate bed plate b associated with adjusting screws c and forming a complete cutter assembly which may either float in the boring-bar or be clamped in position. In Fig. 1 an end recess in the bar is closed by a disc a<SP>1</SP> and the holes t are on opposite sides of the intermediate plate b. Opposite sides of this plate are recessed at b' and tapered to provide a half nut for an adjusting screw c engaging the back of the cutter. The complementary half-nut consists of a separate member d secured to the plate b by screws d<SP>1</SP> to grip the screw firmly after adjustment. The two tools and the plate b are secured by a bolt f. The tool 'assembly may be free to float in the bar or it may be clamped therein by a screw e. In a modification, Fig. 5, the tools slide in dovetail grooves in the plate b and are secured by clamping washers g operated to secure the tools by screws g<SP>2</SP> passing through the half nut members d and the plate b. The cutter assembly may be fixed in position or it may float in the bar a. In one form the floating movement may be controlled by springs 2, Fig. 7, located between pockets in the plate b and cover plates 4. In another modification the cutter assembly may be clamped by screws in a separate member h, Fig. 9, which floats against springs i in the bar a. In another modification for mounting a slot in a bar, the blate b, Fig. 11, may be gapped to receive the reduced end of a screw j which serves as an abutment for the springs k which permit the floating movement. The tools are, in'this case, adjusted by the heads of. screws m, and are clamped by strips n operated by screws n<SP>1</SP>.

Title: Improvements in locomotive boiler furnaces for oil fuel
IPC: F23D99/00
Filed: 1924-01-26
Abstract: 230,230. Martin, J. C. Jan. 26, 1924. Liquid-fuel furnaces.-A locomotive fire-box burning oil fuel is provided with control means by which the feed valve for the fuel and the damper are interconnected so that the damper is fully opened when the valve is opened only a relatively small amount, as when a small or " spot-fire " is burning, the connection providing means for a further opening movement of the valve without movement of the damper. In the arrangement shown the fuel valve 3 for the fuel burner 2 and the damper 6 are connected through link mechanism to the shaft 15, which has an operating handle 12. The damper is connected to the operating shaft through links 9, 10, 21, 20 that provide for a lost-motion device after the damper has been fully opened. This lost-motion is provided for by forming the link 20 in two parts a, b hinged together at c. As soon as the damper has been fully opened, a chain 22 connected to the lever a becomes taut and the links buckle about the pivot c and permit the shaft 15 to be moved further to open fully the feed valve. Upon moving the handle to close the valve 3 the arms a, b are straightened out and the damper is closed. Specification 149,668 is referred to.

Title: Improvements in or relating to devices for carrying bombs and other heavy bodies on and releasing them from aircraft
IPC: B64D1/04
Filed: 1931-01-23
Abstract: 371,876. Bomb-dropping. FRITCSONS, J., 8, Martina lela, and VIKSNE, A., 34, Ormanu Iela, both in Riga. Jan. 23, 1931, No. 2312. Convention date, Jan. 25, 1930. [Class 9 (ii).] Relates to devices for dropping bombs from aircraft of the kind comprising a hook normally locked by a system of levers and adapted to be released by an electromagnet. According to the invention, the hook a and a lever h in engagement therewith are in the form of sectors so arranged that when the parts are in the bomb release position, Fig. 3, the member h cannot be returned to the normal bomb holding position, Fig. 1, until the hook a has first been returned to that position. The member h is locked in the normal position by a projection d on the armature e, Fig. 2, of an electromagnet g until the armature is pulled by the electromagnet or is mechanically deflected by the spindle j of the hook a, which is slidably mounted to permit this. When the hook a releases the bomb as in Fig. 3, it also moves away from a contact k, thereby breaking the circuit of the electromagnet. A lamp may be inserted in the circuit of the electromagnet to indicate when this circuit is closed.

Title: Improvements relating to apparatus for treating water with reagents
Inventor: BLIGHT FRANK CHARLES
IPC: C02F1/52
Filed: 1951-01-30
Abstract: 690,000. Purifying water. PERMUTIT CO., Ltd. Jan. 14, 1952 [Jan. 30, 1951]. No. 2357/51. Class 46 In a method of treating water with a chemical reagent which produces a sludge which settles at the bottom of a tank and is removed through a valve under the head of liquid in the tank the rate of removal of sludge is made proportional to the rate of supply of reagent by operating both the means for removing the sludge and an apparatus for feeding the reagent in accordance with the volume of water supplied for treatment. As shown water to be treated passes throuh a water meter 2 and pipe 1 to a treating tank 3 to which chemical reagent is also supplied through a pipe 4 by a reciprocating feed pump 5 driven by an electric motor 6. The motor 6 is controlled by devices in a control box 7 to which leads from contacts closed by the meter 2 are taken. Upon closing of those contacts by passage of a predetermined quantity of water the pump makes a number of strokes, e.g. four, and then stops, and a wheel is driven through a small part of a revolution by a relay in the box 7. Thus the pump is started and stopped e.g. 20 or 50 times before the wheel makes one complete revolution. When it does so it closes a circuit containing a solenoid 8 so that a valve 9 in a pipe 10 leading from a sludge compartment 11 is opened, and sludge flows under the head of liquid in the tank to a sump -12. The control box 7 also contains a time-delay device which opens the solenoid circuit after a predetermined time to close the valve 9. Appropriate electrical devices are inserted in the wheel circuit if flushing of the pipe 10 prior to opening of the valve 9 is required.

Abstract: Thermoplastic polyesters containing D 4-tetrahydrophthalic acid groups of the formula <FORM:0823224/IV (a)/1> where R1-6 are any of H, alkyl, aryl, or acyl, or OH and esters thereof, R1 or R2 may form endo(m)ethylene bridges with R5 or R6, and R7-8 are H or lower alkyl groups, the polyester having more than 10 ester groups in the molecule and an M.W. of at least 2000, are prepared by subjecting a linear polyester containing dienophilic groups to a dienic addition reaction with a compound having a single system of conjugated double bonds.  This reaction is preferably performed at 0-120 DEG  C. in the presence of an inhibitor such as 1,2-dinitrobenzene or hydroquinone, and the conjugated diene may be used in an equivalent or less than equivalent amount with respect to the dienophilic groups in the polyester.  The polyesters may be derived from butene dioic acids such as maleic or fumaric, with or without such saturated acids as succinic, glutaric, adipic, sebacic, tartaric, acetonedicarboxylic, 3-ketopimelic, or terephthalic and from diols such as hexane diol (1,6), butane diol (1,4), butylene glycol, butene diol and diethylene glycol, with or without such monohydric alcohols as octanol. Conjugated dienes specified are butadiene, cyclopentadiene, cyclohexadiene, and 2-ethyl, 1,3-hexadien-1-ol esters (e.g. acetate). The resultant polymers may be dissolved in chlorobenzene, mixed with unspecified vinyl or acrylic resins or with cellulosic derivatives, or may have their D 4 unsaturation epoxidized, halogenated, hydrogenated or hydrohalogenated.  Addition polymers.-In the case when the conjugated diene is used in less than the equivalent amount with respect to the dienophilic groups in the polyester, the remaining ethylenically unsaturated groups may be copolymerized with styrene in the presence of methyl ethyl ketone peroxide and either cobalt naphthenate or dimethyl aniline.
