Title: Flow divider
IPC: F16K11/07
Filed: 1965-10-12
Abstract: 1,081,856. Valves. BORG WARNER CORPORATION. Oct. 12, 1965 [Oct. 14, 1964], No. 43295/65. Heading F2V. A flow-dividing valve comprises a hollow ported piston 28 acted on by a spring 32 and slidable within a ported sleeve 14 to control flow from an inlet to a priority circuit communicating with port 24 and an excess flow circuit communicating with port 22. At flows below a first predetermined value, all the fluid flows to port 24 via orifices 36, 40 and ports 50, 54a. At flows above the first predetermined value but below a second predetermined value, the pressure drop across orifice 40 moves the piston to the right to allow the additional fluid to flow to the excess port 22 via ports 44, 52, the flow to port 24 thereby remaining constant at the first value. When the flow reaches the second predetermined value, the pressure drop across orifice 36 moves the piston further to the right and increases the capacity of the primary circuit by opening a by-pass passage consisting of ports 44, 48 and chamber 47. At this stage all the fluid passes to port 24 via ports 50, 54b. At flows above the second value, the piston is moved further to the right to allow the additional fluid to flow to port 22 via the left-hand end of the piston, the flow to port 24 thereby remaining constant at the second value.

Filed: 1967-09-26
Abstract: 1,187,300. Making pipe connecting pieces. T.I. STAINLESS TUBES Ltd. 24 Sept., 1968 [26 Sept., 1967], No. 43750/67. Heading B3A. [Also in Division F2] A method of making a connecting piece for connecting together the adjacent ends of a pair of parallel or substantially parallel pipes comprises, forming an annularly hollowed out wheel member and cutting the member into two halves to form a pair of connecting pieces, which each include a passage 13 of generally semicircular configuration. The wheel member is made from parts 10, 11, which are machined from short lengths of steel bar and welded together. In an alternative construction, the member is formed from a pair of identical disc-like elements, which may each be formed from steel bar. One face of each component is hollowed out and the centre portion may be formed with an aperture. The disc-like elements are welded together around their peripheries with the hollow sides juxtaposed and cut into two halves.

Title: Spring wound alarm clocks
IPC: G04B23/03
Filed: 1966-09-30
Abstract: 1,138,178. Alarm clocks. GENERAL TIME CORP. Sept.30, 1966 [Oct.4, 1965], No.43903/66. Heading G3T. In a spring wound alarm clock, the alarm is turned off by applying a downward pressure to the top of the clock housing. A spring 22 drives both the main gear 21 of the timing train 20 and a gear 30 of the alarm drive train. On winding the stem 32, a pinion 35 attached to a star wheel 37 by a shaft 36 is lifted upwards in a slot 47 and ratchets over the teeth of the gear 30. However, on completing the winding, a spring 48 biases the pinion back to the bottom of the slot so that the teeth of the pinion re-engage the gear 30 to prevent backward rotation of the gear. At the alarm time, a cam 56 on an alarm index wheel 55 engages an opening 57 in an hour wheel 25 and the axial movement of the hour wheel shifts an end portion 51. of a clamp 50 away from a stop 52 attached to a clapper 40. The star wheel 37 is thus allowed to rotate and strikes pawls 42, 43 causing the clapper to ring a bell 45. A tip 61 of a blocking member 60 is normally biased away from the teeth of the gear 30 by a spring 63, however on applying pressure to the top of the clock housing, a plunger attached to a base member located in a recess in the bottom of the clock, pushes against an arm 65. The tip 61 therefore engages the teeth of the gear 30, thereby causing the tip to crowd the teeth and stop the gear rotating. A spring biases the base member outwards from the recess. The tip 61 is not released from the gear 30 until the gear is reversely rotated during winding of the spring 22 and the alarm may be permanently shutoff by inwardly depressing a plunger 17. In a modification, the arm of the blocking member extends through apertures in the bottom of the clock and the base member.

Title: Process for the preparation of light hydrocarbon fractions
IPC: C10G65/10
Filed: 1972-09-22
Abstract: 1405664 Hydrocracking SHELL INTERNATIONAL RESEARCH MAATSGHAPPIJ NV 22 Sept 1972 [24 Sept 1971] 43950/72 Heading C5E In a hydrocracking process, when a fresh charge of amorphouscatalyst is first put on stream, the nitrogen content of the feed is kept between 10 and 75 parts per million until the nitrogen content of the catalyst, and therefore the temperature needed to maintain a given conversion, reach equilibrium; it is then reduced to less than 5 p.p.m. for the-rest of the run. If the feed has a nitrogen content less than 5 p.p.m., this can be brought up to 10-75 by adding ammonia, methylamine, aniline or pyridine. Alternatively, if the process, of the invention is the second step of a two-stage process, the changes in nitrogen content can be obtained by changing the severity, e.g. the temperature, of the first step. In the example, a middle-eastern flash distillate with a nitrogen content of 600 p.p.m. is hydrocracked in two stages. First stage catalysts are of. nickel sulphide; tungsten sulphide and fluorine on alumina and of nickel sulphide, molybdenum sulphide and florine on alumina. The temperature in the first stage is chosen to give an effluent of the right nitrogen content. The catalyst in the. second stage is of nickel sulphide, tungsten sulphide and fluorine on silica-alumina. The effluents of both stages are mixed and fractionated into a C 1  and C 2  fraction, a C 3  and C 4  fraction, a light gasoline (to 65‹ C.), two naphtha fractions (65-120‹ C. and 120-185‹ C.) and a residual fraction used as feed to the second stage.

Abstract: 941,482. Synchronous machines. GENERAL ELECTRIC CO. Dec. 28, 1959 [Jan. 19, 1959], No. 44024/59. Heading H2A. A brushless synchronous generator has auxiliary windings on both stator and rotor serving as an exciter feeding the main rotor winding through a rectifier mounted on the rotor, the main and auxiliary windings having different numbers of poles and being mounted in the same rotor and stator slots. In the form shown in Fig. 2, an eight-pole D.C. winding 16 excites an eight-pole auxiliary winding 28 which feeds the four-pole main field winding 30 through rectifiers 32. The rectifiers are mounted on a fan blade for cooling. In a modification, Fig. 3, the stator field winding 16 is excited from the star point of the main A.C. winding 18 by means of oppositely connected rectifiers 34 to give current compounding. Shunt excitation is provided through a rectifier 40 and regulator 41 feeding stator field winding 38, and separate excitation is provided by winding 43. Building up may be ensured by using hysteretic rotor and stator laminations. The stator stack is welded and located by dowels.
