Abstract: 729,989. Joining tubes to plates. BABCOCK & WILCOX, Ltd. Aug. 14, 1953 [Aug. 15, 1952], No. 22432/53. Class 99 (1). [Also in Group XXII] A method of manufacturing tubular heat exchangers includes forming each of a number of tubes with end portions of different diameter, fitting the ends into tube seats of appropriate diameter formed in spaced heat exchanger walls, expanding the larger end of the tube in its seat to form a joint and then expanding the smaller end of the tube in its seat to form a joint by an expanding operation causing tube metal flow away from the expanded larger end. A tube 10 with a smaller swaged down end 12 is fitted between spaced heat exchanger walls 14, 16 with the larger end 13 in a tube seat 18 in the wall 14 and the smaller end 12 in a smaller tube seat 20 in the wall 16. A ball drift expander 26 is then pushed through the larger end 13 from the outer end inwardly to expand it in its seat. The expander 26 is withdrawn and a smaller ball drift expander 34 is pulled through the tube to expand the smaller end 12 in its seat outwardly to the tube end. A large number of closely spaced tubes may be thus secured between the walls 14 and 16.

Title: An improved method of mounting photographic transparencies
IPC: G03D15/10
Filed: 1963-06-06
Abstract: 1,039,175. Transparency mounts. E.I. DU PONT DE NEMOURS & CO. June 6, 1963 [June 22, 1962], No. 22554/63. Heading G2C. A transparency mount comprises two sections 5, 6, each having a window. The sections abut together at each side, beyond the window, and may be pressed together so as to rock about the said abutments, which causes the sections to flex away from each other, as shown. The increased width of the opening 4 thus facilitates the insertion of the transparency without scratching it. In Fig. 4 the flexure is caused by pressure in the direction of arrows 8, i.e. parallel to the optical axis. In Fig. 5  the pressure (arrows 17,18) is perpendicular to the axis. The insertion may be carried out by an automatic machine.

July 28, 1930, Nos. 22685 and 30581. [Class 117.] In light-sensitive sorting apparatus, in which regularly spaced control areas 3, Fig. 1, are passed behind a mask 4 and observed by a light-sensitive cell, the mask is so proportioned and arranged as to disclose one control area plus one intermediate space. A cylindrical or spherical mirror 1, or the optical equivalent, Figs. 2 to 6 (not shown), are interposed between the mask and the cell to reflect the light on a substantially stationary portion of the light-sensitive area. The cell 1A, Fig. 9, is connected to an amplifier A, including a valve 38 which is so biased by a potentiometer 40 that no anode current normally flows. As shown the amplifier comprises three stages and the first valve 34 operates on a steep part of the characteristic curve, the second operates at the bottom of its curve, and the third 43 near the bottom of its curve. Duplicate circuits are used, one of which A acts on a change from dark to light, and the other B on a change from light to dark. The amplifiers are connected to differential coils 21, 22 on a magnetic trigger 20, Fig. 10.

Title: Improvements in sorting apparatus
IPC: B07C5/342
Filed: 1936-08-18
Abstract: 468,815. Sorting beans &c. by lightsensitive apparatus. TATE, F. R. (Electric Sorting Machine Co.) Aug. 18, 1936, No. 22762. [Class 40 (iii)] [Also in Group XXX] In apparatus for sorting beans or like articles in which the articles are fed into a hopper and caused to adhere to the periphery of a rotary drum while being carried past photoelectric apparatus which causes discoloured articles to be removed from the drum, the photo-electric cell is mounted in a lamp casing through which the conveying drum passes. The beams are picked up from a hopper 12, in which they are agitated by a mechanically-reciprocated blade 15, by means of metal-lined suction orifices on the periphery of the rotary drum 3 and are carried first past strippers 16 which limit the picked-up beans to one per orifice, and then through the orifice 27 to the casing 20 where they pass a photoelectric cell 26 while being illuminated by the lamps 25. Beans which are uniform in colour with the periphery of the member 3 pass the photo-electric cell without interference and finally pass into the zone 44 when the suction is cut off, so that they fall by gravity down a shoot 45. Discoloured beans cause the cell 26 to actuate a stripper member 28, Fig. 3, which knocks them off into a separate shoot 24. The stripper is operated by means of a solenoid 30 which is moved against the action of a spring 32. The cell operates the solenoid through electrical relays. A commutator is interposed in the circuit between the relays and the solenoid and is driven in synchronism with the drum 3 to ensure that the current initiated by the cell is cut off before the next bean registers with the opening 27. In a modification, a single central hopper serves rotating drums on either side of it.

Abstract: 227,781. Ternstedt Manufacturing Co., (Assignees of Edgar, F. M.). Jan. 17, 1924, [Convention date]. Catches, yielding to pull and pressure.-In n resilient-buffer device in which a striker on the door engages between a pair of members on the door jamb, the keeper socket-member is constructed so that there is exerted a thrust in planes both parallel and transversely to the door. The socket member comprises a plate a behind which in a casting care ,ecured rubber blocks d that tend to force the plates e towards each other. The plate a is cut away to expose the ends of the member e so that the tapered striker g on the door may be engaged with and wedged between them. The acting surfaces of the grip-plates e are shaped to converge in two directions, one in a plane parallel to the door and the other in a plane transversely thereto. The striker g is shaped in a similar manner, and it is conveniently formed as a sheet metal stamping. As the door closes and the parts engage, the thrust in a plane parallel to the door and away from. the engaging members prevents it rattling on its hinges, and the thrust in a plane that is transverse to the plane of the door forces the latch bolt against the side of the lock casing and prevents it rattling.
