Title: Improvements in and relating to traverse control mechanism for artificial silk, and like spinning machines
IPC: D01D7/02
Filed: 1945-11-19
Abstract: 603,061. Spinning artificial silk &c. DOBSON & BARLOW, Ltd., and HARTLEY, W. Nov. 19, 1945, No. 30968. [Class 120(ii)] In a machine for spinning artificial silk and the like by centrifugal action, a differential gear-box is interposed between the main shaft which rotates the spinning pots and a driven shaft which operates the traverse of the funnels. The gear box carries the differential pinion or pinions and is rotated by a drive from the main shaft so as to cause the speed of rotation of the said driven shaft to differ from the speed of rotation of the pots, thus preventing "synchronisation" which causes ridged winding. As shown, main shaft 6 is connected to driven shaft 7 through a differential gear housed in gear box 8 which carries the differential pinions. Gear box 8 is slowly rotated by a star wheel 9 which is affixed thereto and which is turned by a pin 11 on the face of a wheel 12 rotated by shaft 6 via gears 14, 15. The speed of rotation of shaft 7 is thus caused to differ slightly from that of shaft 6.

Title: Improvements in or relating to mosaic photography
IPC: G03B37/04
Filed: 1957-10-03
Abstract: 854,056. Mosaic photography. FOREIGN DIETERICH CORPORATION. Oct. 3, 1957 [Oct. 31, 1956], No. 31039/57. Classes 97(1) and 98(1) Apparatus for carrying out mosaic photography includes two cameras, one arranged for viewing its section of the scene directly and the other for viewing its section by reflection in a mirror, the latter camera comprising a housing supporting an axially movable lens assembly and movable transversely to the lens axis on a supporting framework so that the position of the lens assembly may be adjusted to make both cameras view the scene as from a single point irrespective of the range at which they are focused. As shown in Fig. 2 three cameras A, B and C are axially movable on guideways 16 on a table 2, the camera B recording directly and cameras A and C recording by reflection in mirrors 20. The diaphragm settings of the three cameras are effected simultaneously by rotation of a shaft 154, driving shafts 158, 160 which operate the diaphragms through magnetic couplings which may be disengaged to allow movement of the cameras along the guideways 16. To permit the transverse movement of cameras A and C each is mounted on a frame 86 (Fig. 4) to which it is linked by a micrometer screw 88 rotated by a shaft 96 driven by suitable servo mechanism to move the cameras simultaneously. Each objective 46, Fig. 4 is mounted on a sliding member 84 attached to an insulating plate 76 carried by resilient members 80 connected to the camera base 68. The insulating plate 76 carries a coil 82 located between the pole pieces 66, 72 of a magnet so that passage of an electric current through the coil causes sliding movement of the member 84 and so adjusts the focus of the lens 46. By this means the focus of the three cameras may be adjusted simultaneously.

Title: An improved process for the conversion of neutral or nearly neutral triglycerides, mutually or with other esters
IPC: C11C3/10
Filed: 1924-12-30
Abstract: 249,916. Loon, C. van. Dec. 30, 1924. Fa.ts and fatty oils.-Neutral or nearly neutral triglycerides are heated with catalysts in order to effect interchange of the acid radicles. The catalysts are of the type which catalytically promote the esterification of free fatty acids and free alcohols or the action of free alcohols or free acids on triglycerides. The interchange may be intramolecular. Interchange of acid radicles between triglycerides and non-glyceride esters may be similarly effected. The catalyst may be an aromatic or aliphatic-aromatic sulpihonic acid, metals such as cadmium, lead, tin or zinc, and compounds thereof, a heavy metal or mixture or alloy of heavy metals, or a heavy metal compound, an alkali or alkaline, earth metal compound, or mixtures of these catalysts. The reaction may be performed under reduced pressure and in inert gas. The process may be combined with hardening processes by using a combination of two catalysts, one for each process. The process may be combined with other known processes for treating oils or fats such as refining. The melting-point and solidifying points are said to be changed. In the examples, cocoabutter is heated with sodium ethylate as catalyst, tristearine and soya-bean oil are heated with stannous hydroxide in hydrogen, and cocoanut oil and ethyl stearate are heated with tin powder in carbon dioxide. Specifications 15031/84. 13382/07: 2306/14, [Class 1 (i), Chemical processes and 193,099 are referred to.

Title: Improvements in magazine gramophones
IPC: G11B17/16
Filed: 1936-11-16
Abstract: 485,562. Magazine gramophones. CLARKE, H. M. G. Nov. 16, 1936, No. 31259. [Class 40 (ii)] Relates to magazine gramophones in which the turntable 1 is on a substantially horizontal axis, and consists mainly in holding the record against the turntable by means of a rod 10 axially displaceable in the turntable spindle 3. One end of the rod 10 has a lip 12 on one side and a bevel 11 on the other side : and the other end of the spindle has a collar 13 with a finger 14 and is influenced by a coiled spring 20. The lip 12 holds the record against padded raised portions or a rubber pad 2 on the face of the turntable 1, which is small in diameter so as to leave both sides of the record exposed for play. A pick-up or sound-box (not shown) is arranged on each side of the record to play either side or both. When the playing of the record is completed, a projection 38 rocks a cam 37, which pulls on a wire rope 21 and rocks a lever 17 about its pivot 16. The lever 17 bears on a fork 15 swivelled to the collar 13, or directly on this collar and pushes the rod 10 to the left. The lip 12 unclamps the record ; and when the rod 10 in following the rotation of the turntable shaft 3 brings the bevel 11 to the top, the record falls on an inclined bed 45, which leads it through an aperture 47 into a receptacle 48. In its continued displacement to the right, the rod 10 brings the finger 14 opposite a fixed stop 24, which arrests rotation of the rod when the lip 12 is at the top ; and at the end of the movement, the rod 10 presses a sleeve 29 against a spring 35 on the extension 27 of the inclined stem 25, on which the records to be played are threaded. The lowermost record is held by a projection 28 on the extension 27, which is eccentric to the stem 25. A slot 30 in the sleeve 29 embraces the projection 28, and the ends of the edges of the slot are bevelled, so that when the sleeve is pressed in by the rod 10 the lowermost record is lifted from the projection 28 and allowed to slide down the extension 27 on to the rod 10, while the next record is held up by the bottom of the end of the sleeve. When the rod 10 is returned to the right by the spring 20, a fresh record slips on to the extension 27 and against the stop 28, while the record on the rod 10 is carried against the turntable and clamped thereto by means of the lip 12. When the finger 14 leaves the stop 24, the rod 10 is again free to follow the rotation of the turntable. The turntable spindle 3 carries a fly-wheel pulley 4 driven by a belt 6 from a motor 9.

Abstract: 511,768. Extracting oil by distillation from oil-bearing strata. BENSON, M. Nov. 19, 1937, No. 31842. [Class 55 (ii)] [Also in Group III] To improve the recovery of oil from wells, especially after the natural gas pressure has fallen, some or all of the oil is heated to or above the critical temperature by means of an expansive fluid, e.g. superheated steam, while a pressure above the critical pressure is maintained. Up to the critical temperature the more volatile fractions of the oil remain dissolved, thinning the liquid and facilitating drainage to the well; at the critical temperature the whole of the oil is vapourized without change of composition. Drainage is also facilitated by the reduction of surface tension and viscosity near the critical temperature ; condensation of the steam re-saturates the sand. The pressure and temperature may be the highest practicable having regard to the nature of the cap rock and the materials of the plant ; it is stated that the natural gas pressure in a well may be several thousand lbs. per sq. in. and plant using stainless or low-carbon steel (C=0.35 to 1 per cent.) is available in which steam may be superheated to 1,000‹C. The steam may be superheated by direct heating (electric or other) or by internal firing with a fluid fuel and air, oxygen, or both. The pressure may be controlled by a backpressure device (valve. de Laval nozzle, or turbine) on the well, and this device may be at the outlet of a condenser or cooler serving also as feed-water heater or steam generator. The oil may be fractionated during condensation, either without or with cracking. The steam &c. may be introduced to one of a group of wells.tapping a single pool. The process may be used in a partially-flooded oil-field.
