Title: Improvements in loading and discharge pipe line apparatus for oil tankers
IPC: B67D9/02
Filed: 1921-11-29
Abstract: 195,428. Dorman & Co., Ltd., W. H., and Steed, O. H. G. Nov. 29, 1921. Hinge and swivelling joints.- A pipe line for the loading and discharge of oil tankers extends between the ship's tank and a storage reservoir, and consists of a number of lengths of rigid piping connected together by universal and / or rotary joints, so disposed and supported as to permit of relative movement, in all directions, between the two ends of the pipe line. In the form shown in Fig. 1, the full lines indicate the pipe line 1, 2, 3 in the position when the ship is at its extreme distance from the quay Q, other critical positions, due to rise and fall of tide and pitching and rolling of the ship, being shown in dotted lines at A, B, C. The connections between successive lengths of pipe line may comprise two right-angled bends 7, 8 and two simple rotary joints 9, 10 rotatable in planes at right-angles to one another. The joints may be of the kind described in Specifications 129,812 and 186,166. The pipe line is supported at 13 by an adjustable overhead suspension line 22, which passes over a laterally movable pulley 23 sliding on a shaft 24 mounted between the sides of the framework of a counterbalanced gantry G, pivoted at the tops H of bar supports sunk into the concrete of the quay. Adjustment of the suspension line is secured by a handwheel operating the winding drum 25 through a worm and wormwheel gearing.

Title: Improvements in and relating to Evaporators
Inventor: RIVA PIETRO
IPC: B01D1/06
Filed: 1966-07-18
Abstract: 1,157,816. Evaporators, vapour compression type; automatic control. P. RIVA and G. RIVA..18 July, 1966 [13 April, 1966], No. 32200/66. Heading B1B. An evaporator of the . vapour-compression type, openated by mechanical compressor I driven by motor M, is provided with auxiliary heaters R 1 , R 2 , R 3  in the heatinig chamber D, and with a by-pass from the pipe N so that the vapours may pass from the heating chamber in to the condenser B without going through the compressor. The opening and closing of the by-pass is gradually controlled by motorised valve EV2 and thermometer K, which has contacts for maximum and minimum values, associated with electrical relays, servomotors, and a programmed switch. The solution to be evaporated is supplied from tank G4 which is under reduced pressure. The evaporator is equipped with a 'magnetic contact G1 responsive to liquid-level therein, a compressor purge valve EV3, and a concentrate discharge valve EV4. The control system operates so that the supply of solution to the evaporator, 'the preheating of the solution, the starting-up of the compressor, operation of the evaporator under steady state conditions, and shutting down of the evaporator are automatically and successively controlled. The distillate and residual non-evaporated solution (concentrate) are withdrawn from the evaporator through heat-exchangers E and H, respectively. Heaters R 1 , R 2 , R 3  may be electrical resistance heaters, or they may 'be coils supplied with heating-vapour. On closure of the contact of the programmed switch, the valve EV 1 which controls the supply of solution of tank G 4  is opened; and the servomotor of valve E v2  is put in operation. The solution flows from tank G 4  through heat exchangers E, H, and then through chamber D before it enters the tubes of the heatercondenser B. When the solution reaches the level determined by magnetic contact G 1 , the auxiliary heaters R 1 , R 2 , R 3  are put into operation. When the solution boils, the vapours flow into the compressor and heat it until the thermometer K reaches its maximum contact; the valve E v2  is then opened, and heater R 2  is made inoperative. Valve E v2  then closes. After steady state operation for a predetermined time, the programmed switch opens its contact, and the evaporator is shut down. 'If, during operation, a condition of excess vacuum arises in the evaporator, detector device V energises a relay which puts the evaporator out of action, and a signal lamp indicates the reason.

Title: Adjustable seat mechanisms, in particular for motor vehicle seats
IPC: B60N2/225
Filed: 1966-07-19
Abstract: 1,091,994. Adjustable seats. P. U. PUTSCH and F. W. PUTSCH. July 19, 1966, No. 32316/66. Heading A4J. [Also in Division E2] In a hinge fitting for supporting a vehicle seat back at a continuously variable inclination, relative rolling movement between unequally toothed gears 13 and 28, produced by revolving the axis of one of them eccentrically around the axis of the other, provides a reduced relative angular displacement between the gears, thus altering the inclination of the seat back relatively to the seat base frame, to which they are respectively riveted, by means of fixing holes 30. That gear 13 or 28, which is not riveted to the seat base frame, has its axis revolved eccentrically by means of an eccentric portion (18, Fig. 1, not shown) of a stub axle (16) or an eccentric sleeve (37, Fig. 5, not shown). The axle (16) or sleeve (37) may be rotated by a knob (26) or (26<SP>1</SP>) or by a manually rotatable flexible shaft (17) or (17<SP>1</SP>). Alternatively, the shaft (1711, Fig. 9, not shown) may be driven by an electric motor (58), through a reduction gear (57). A rubber ring (23) or 46) provides compensation for manufacturing tolerances.

Patent GB-621890-A (GB)
Title: Method of nitriding ferrous metal alloys
IPC: C23C8/26
Filed: 1946-11-04
Abstract: In a process of nitrogenizing ferrous metal alloy, the alloy, heated within the nitrogen hardening range, is treated with dry gaseous ammonia and its dissociation products showing an ammonium dissociation value which rapidly produces a white layer, continuing the treatment until a thin continuous white layer has been formed, then increasing the ammonium dissociation value so that the tendency to form a white layer is lessened and continuing the treatment until the necessary depth of case has been obtained.  The alloy may be heated in a furnace at 925 DEG  to 975 DEG  C. for 5-15 hours during which ammonia is introduced to give a dissociation value of 15-65 per cent, preferably 30-40 per cent, and then for 10-90 hours when the dissociation value is 65-85 per cent.  This dissociation value may be raised to 85-90 per cent for a final period and maintained till the white layer has been completely removed.  The ammonia dissociation may be controlled by regulating the rate of flow of the ammonia into the chamber. The gaseous atmosphere should be kept rapidly agitated so that the dissociation is maintained constant throughout the chamber.  A suitable alloy is one having an analysis C .34 per cent, Mn .55 per cent, Si .25 per cent, Cr 1.30 per cent, Al 1.24 per cent, Mo .17 per cent and the balance iron and unavoidable impurities.

Abstract: 812,205. Adhesive tape dispersers. DERBY SEALERS Inc. Oct. 30, 1956 [Nov. 7, 1955], No.38085/56. Class 18. A tape dispenser of the kind wherein a lever is depressed to feed forward a length of gummed tape, has a serving member operated by the lever to sever the tape on return movement of the lever. The lever 26 is connected by gearing 30, 55, 56 to the lower of feed rolls 15, 16, the tape 13 passing along a platform 14, between the rolls, through an aperture 58 in the knife 37 and over gum moistening means 22. The lever 26 is fixed on a shaft 25 and is connected to the gear 30 by a coil spring 32 which, during downward movement of the lever against a spring 53, is expanded to a driving fit inside a drum 31 fast on the gear 30. On return motion of the lever, the spring 32 contracts to release the drive. The shaft 25 carries a cam 29 for operating the knife. The knife has an aperture 46 for the end of a lever 40 pivoted at 42 and operated on by the cam 29. The knife is normally in a position to obstruct the feed, as in Fig. 3. When the lever 26 is depressed, a slight lost motion between the spring 31 and its connection to the shaft 25 delays forward feed of the tape, but the cam 29 contacts part 48 of the lever 40 to raise the knife 37, and hold it raised by a surface 50 during tape feed. When released, the lever returns, enabling a pin 52 on the cam 29 to engage part 47 of the lever 40 to pull the knife downwards and cut the tape. The length of tape fed may be adjusted by a moveable stop limiting the travel of the lever 26. Reference has been directed by the Comptroller to Specification 740,328.
