In an oil burning installation a lockout heater 12 is in series with the operating winding 16 of a fuel pump and shuts down the installation by operating a bimetallic switch 8 unless it is short or open circuited as a result of flame sensing by a photoconductive cell 29. The illustrated circuit is shown at starting when closing of a switch 1 energizes the starting winding 23 of the pump motor and an igniter 31. When the motor reaches its operating speed a centrifugal switch 21 is thrown and flame serving by the cell 29 causes a relay 15 to throw switches 13-14, 17-26and 27-28 to opencircuit the lockout heater and the igniter. In other embodiments the motor starting winding may be energized through the switch 17-26, the lockout heater may be short circuited on operation of the relay 15, and the centrifugal switch may be replaced by a switch operated by fuel pressure on the outlet side of the pump.

Patent GB-458885-A (GB)
Title: Improvements in and relating to diagnostic agents and the production thereof
Filed: 1935-12-11
Abstract: Preparations, for use in diagnosing carcinoma, sarcoma, and predisposition thereto, are obtained by retaining matter taken from the intestines of sufferers from these diseases at a pH of 5-6 until the bacteria coli are destroyed, transplanting a pure culture of the remaining bacteria to a nutrient solution containing fat, such as fatty milk, and cultivating the transplanted bacteria for some time, e.g. several days.  The culture, e.g. from a carcinoma patient, is acidified (e.g. with sulphuric or phosphoric acid) and extracted by solvents such as ether or petroleum ether, preferably after a separation of protein matter by addition of alcohol or by heating. The acid substances in the organic extract are taken up in an alkaline solution, reprecipitated and redissolved in ether.  The effective substances being of lower solubiilty are separated from palmitic &c. acids by fractional crystallization or by adsorption on kaolin, silica, &c. The substance so obtained is crystalline and readily soluble in organic solvents and has the character of a non-saturated high molecular fatty acid.  When added in solution or suspension to clear extracts of carcinoma cells precipitates are formed, none being produced with other proteins.  For the preparation of diagnostic material the substances are converted into alkali salts, dilute solutions of which when injected into healthy subjects cause some reddening and evanescent swelling, while in the case of those suffering from or predisposed to carcinoma a hard and sharply defined infiltration arises.  Similar procedures are adapted to obtain products for sarcoma diagnosis.  The products may be purified by distillation under vacuum; they may be stored in the crystalline form or in weakly acid aqueous suspension.

Abstract: 647,359. Thermal switches. DANSK TELEFONALARM AKTIESELSKAB. Dec. 30, 1947, Nos. 34898, 34899 and 54900. Convention dates, April 13, 1945, Jan. 23, 1946 and Jan. 23, 1946. [Class 38(v)] A thermal switch of the differential type, for use in a fire alarm system, comprises two or more thermal elements, one of which is insulated from the surrounding medium to a greater extent than the others, the difference in expansion of the elements on a rapid rise in temperature moving a contact-operating armature into the field of a magnet. In Fig. 3, two bimetal spirals 10a, 10b, are fixed at their outer ends 46a, 46b, and are connected at their inner ends to a spindle 16 carrying an adjustable sleeve 26 to which is fixed the inner end of a bimetal spiral 12. The spirals 10a, 10b, 12 are contained in chambers 36, 38, 40, respectively, in a housing 34, the chambers 36, 38, having air vents 42. On a rapid rise in temperature, the spirals 10a, 10b, rotate spindle 16 clockwise before spiral 12 can counteract the rotation, and an arm 28 carried by the spiral 12 moves a spring 18, fixed at its lower end away from a stop 32 so as to carry an armature into the field of the magnet 22a, 22b, 22c, thereby operating contacts 24a, 24b. An indicator 74 is formed on the end of spring 18 and is viewed through an aperture 76 in the casing. The spring 18 may be adjustably pre-stressed by a screw 66 which bears against a tongue 72 on the spring. In a modification, Fig. 1, (not shown) a single bimetal spiral replaces the two spirals 10a, 10b. In a further modification, Fig. 4 (not shown) the sleeve 26 carries an arm which engages an abutment on the arm 28 to actuate the switch when a predetermined temperature is reached. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specification 648,983. This subject-matter does not appear in the Specification as accepted.

[Also in Group XXIV] In a Hook's type universal joint accurate axial alignment of a spider 3 and yoke 4 is obtained during assembly by axially aligning the spider 3 and yoke 4 and sliding needle bearing cups 6 in bores 9 of the yokes until they abut the spider trunnions 7 whereafter retaining plates 10 are force-fitted into the bore and welded in position. As shown, the retaining plate 10 is we'ded in position by electric resistance welding, one electrode A being applied to the plate 10 while the other electrode B is applied to a machined surface on the yoke 4. In Figs. 7 and 8 (not shown) a semi-circular retaining plate is welded in position by applying one electrode to the straight edge of the retaining plate and the other electrode to the interior of the bore in the yoke, the electrodes forming a kind of plier, the branches of which spread apart when the weld is effected. In Figs. 9 and 10 ( not shown) a split ring retaining member is welded in position by applying a two-part electrode in the form of a plier within the ring to expand the latter into engagement with the bore in the yoke whilst the other electrode is applied to a machined surface of the yoke. A two-part retaining ring may be welded in position by applying an electrode to each part of the ring. In Fig. 11 (not shown), a dielectric is inserted between the bearing cup and the retaining plate to prevent the welding current passing through the former.

Abstract: 475,455. Universal joints. PARENT, J. A. Dec. 19, 1936, No. 34976. Convention date, Dec. 21, 1935. [Class 80 (ii)] [Also in Group XXV] Relates to a universal joint of the type comprising two cardan joints united by a casing 4 which encloses the ends of the shafts 1, 2, the axes of which are maintained concurrent by a ball-and-socket joint 12, 14. According to the invention, the ball has a parallel part machined on it, Fig. 7, so that it will just enter the socket, Fig. 13, which has V-shaped slots 12b, 12c, into which the stem 12a of the ball can enter to allow great angularity of the joint. As shown, the joint comprises two Hooke's joints connected by a double-spherical casing 4. The cross members 3 are supported by trunnions, Fig. 4, in the casing 4, and carry rings 6 in which the ends of the shafts are trunnioned at 1a, 2a. The rings 6 are kept in place and the shaft ends are located in the cross members 3 by discs 7 secured by springs 8 which snap under projections on the members 3. The trunnions 9 for the cross members 3 are held by spring clips 11, with loops d to fit over projections on the casing 4, the ends of the member 3 being located by discs 10 held in position by discs 10a forced into umdercut grooves in the trunnions 9. The stems 14a, 12a of the ball-and-socket joint are journalled in the ends of the shafts 1, 2, and the socket is constantly urged into engagement with the ball by a spring 15. To prevent the stem 14a from locking on the ridge 12d between the slots 12b, 12c, spring-pressed pins P, PI, Figs. 13, 15, are provided. In the position shown in Fig. 15, the stem 14a has descended exactly on the point of the pin P which is compressed until the ridge 12d touches the stem. The pin P is then pressed right into its socket and the stem 14a slides down the incline R. If the stem comes to the right of the position shown, it slides down the incline R1.
