Title: Improvements in or relating to processes for stapling fibres of polyesters
IPC: D01G1/02
Filed: 1956-11-30
Abstract: 854,900. Stapling polyester fibres. FARBWERKE HOECHST AKTIENGESELLSCHAFT VORM. MEISTER, LUCIUS & BRUNING. Nov. 30, 1956 [Nov. 30, 1955], No. 36768/56. Class 120(3). In a process for stapling polyester fibres, bundles of slivers of continuous filaments are locally treated with guanidine carbonate alone or with other compounds and the treated material is subjected to such conditions that breaks occur at the treated places. The filaments may be of the polyterephthalic ester of ethylene glycol, and the guanidine carbonate may be used with glycol or its derivatives, or qualernary ammonium com-  pounds, applied thickened with gums, at equidistant or non-equidistant places by engraved &c. rollers, stencils or screens. The description may take place by heating, or stretching after or both before and after, the application : it may be affected after weakened filaments have been woven or knitted. Untreated filaments may be mixed with treated filaments or the treatment may be applied to polyester yarns mixed with other yarns.

Abstract: 825,202. Milling and boring-machines. VICTORIA MACHINE TOOL CO., FRYE, J., and SEIDEL, A. March 21, 1956 [Dec. 22, 1954], No. 37041/54. Class 83 (3). A milling - machine comprises a vertical column 3, Fig. 1, a knee 4 projecting therefrom and carrying a worktable 5, an arm 7 extending horizontally from the top of the column above the table, and a yoke 8 extending down from the arm and carrying a bearing for the outer end of cutterarbor 1, the inner end of the arbor being connected to a driving spindle in the column. The machine may be set-up with the arbor removed, the arm displaced to the left, and a facecutter connected to the driving spindle. The arm may be turned about axis x-x to position the opposite end over the work-table, which end has an angularly-adjustable body 15 carrying an electric-motor 13 for rotating a spindle 12, Fig. 4, and feeding a quill 14, in which the spindle is mounted, and which may carry a milling or boring-tool. The motor drives, via step-pulley 19 and a belt 20, a steppulley 21 secured to a sleeve 22 which may be coupled to a sleeve 25, directly via dog-teeth 30, 33, or via reduction gear between pinions 29, 31. The quill is fed by a pinion 69 on a shaft 67 engaging rack-teeth 70, the shaft being turned either manually via hand wheel 104, Fig. 10, or by the electric motor, when clutch 75, 76 is closed, via change-speed and reverse gearing (not shown), connecting the clutch to pinion 32. The clutch-actuating rod 79 is urged to the release position by a spring 84, and is retained in the engaged position by a projection 97a on a rod 96 engaging a detent in a disc 95 secured to rod 79. Rod 96 may be moved against a spring 97 to disengage the detent and stop the power-feed, either manually by a lever 105, or automatically by bobbin 94 on a shaft 85 being moved axially by a projection 100 on the quill engaging adjustable abutments 98, 99 on the shaft, which is centred axially by springs 90, 93, the feed in either direction being stopped. To provide a positive-stop to downward movement of the quill, a member 109 on lever 105 is pivoted to the position shown, in which it lies between bobbin 94 and a fixed surface 112. In this condition the power-feed-clutch must be held engaged, since the projection cannot engage disc 95.

Heading B1B [Also in Division F4] Material is dried by introducing it into a flow of gas which oscillates but has a resultant flow in one direction. For example ground whole fish is pumped into the exhaust pipe 26 of a pulse jet engine 48. In the apparatus described, about 15%, depending (on the distance of the point of introduction of the material from the downstream end of the exhaust pipe, of the moisture is removed here and the material then passes from the exhaust pipe into a drying chamber containing vortices set up by further pulse jet engines such as 55, 56 where the material is dried to fish meal. The lighter particles leave the chamber through the exhaust gas duct 72 and the heavier particles fall through opening 74. The pulse jet is of the valveless typs having the combustion chamber (22, Fig. 2, not shown) nearer the inlet than the outlet (38). The flow through the inlet also fluctuates, the engine drawing cool air in and blowing hot air out. This is directed through an aug,mentor tube 28 into the drying chamber. The two engines 54, 56 are directed at about 30‹ to the horizontal and are inclined to the tangents to the chamber wall. Two other engines (58, 60, Fig. 4, not shown) are horizontal and tangential. The vortices are stabilised by a cone 62 and an apertured plate 64. The drying chamber may alternatively be used with the engine 48 alone.

Title: Improvements in or relating to gyroscope systems
IPC: G01C19/38
Filed: 1955-12-30
Abstract: 793,274. Electric control systems. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Dec. 30, 1955 [Dec. 31, 1954], No. 37438/55. Class 40 (1). In a gyroscopic system for navigational purposes in which the correct positioning of the gimbals of the gyroscope is checked by means of a gimbal-mounted pendulum, both the pendulum and gyro have selsyn devices coupled with their gimbal shafts, corresponding pairs of selsyns being interconnected so that relative movement of normally parallel shafts creates an unbalance signal which is used to operate correction devices to apply appropriate correcting forces to the gimbal mounting. Fig. 2 shows diagrammatically an arrangement in which a selsyn transmitter 14 is mounted on the gyro gimbal and a selsyn transmitter 20 on the corresponding pendulum gimbal. To avoid reaction on the gyro gimbal caused by positional differences between the two selsyns, selsyn 14 controls a servomotor 31 which positions a third selsyn 32 in accordance with the position of the gyro gimbal. Positional disagreement between the third selsyn and selsyn 20 is sensed by a discriminator circuit 35, 36 and used to control a motor 26 which applies a force to the other gyro gimbal, thus indirectly correcting the first one. Servomotor 31 may be omitted and selsyn 32 mounted directly on the gyro gimbal. Fig. 4 shows an arrangement for controlling both gimbals by means of motors 55, 71. Pendulum controlled selsyns are shown at 20, 21 and gyro controlled selsyns at 32, 60 positional disagreement is sensed by circuits each of which comprise a pair of rectifiers 44, 45 feeding a centre-tapped relay winding 46. Thus, according to the direction of the error one half or other of the relay is energized and causes one of a pair of contacts 49, 50 to drive the correcting motor 55 in one direction or the other. Relay windings 75, 76 shunted by condensers 73, 74 and connected in the error circuits, operate contacts 77 if the error exceeds a certain amount. This contact opens the circuit of a resistor 38 in series with one of the servomotor windings, the effect of which is to reduce the error slowly. When the error is large, the circuit of the resistor is opened and can only be restored without the resistor to provide fast error reduction by closing manual switch 37 which operates relay 80 which locks and re-energizes motors 55, 71 without the series resistor. The error is thus rapidly reduced. When it is below a lower figure than that at which the resistor was inserted, relays 75, 76 open the circuit of relay 80, resistor 38 is reinserted and the error is slowly reduced.

Abstract: 1,221,945. Sealed beam lamp. JOSEPH LUCAS (INDUSTRIES) Ltd. 31 July, 1968 [16 Aug., 1967], No. 37694/67. Heading F4R. [Also in Division H1]  In a sealed beam lamp the distorted area or areas of the reflector of the lamp around the point or points where some or all of the electrical supply leads for a filament of the lamp pass through the reflector, is or are non-reflective. These areas are made non-reflective during manufacture of the lamp by masking the areas when the remainder of the reflector is rendered highly reflective by aluminizing. A casing 11 has secured therein a sealed beam lamp 14 bymeans of a clamping ring 13, the lamp being filled with an inert atmosphere. A quartz iodine bulb 32 is mounted in a ceramic holder 26, the leads (24, 25) of the bulb being led through holes (27) in the holder and welded to the supply leads 23 (22) passing through the reflector 15 (Figs. 2, 3 and 5, not shown). The supply leads 23 (22) are joined to conductors 17, 18. The pitch (39) of the bulb 32 fits in between two blades (29) on the ceramic holder 26. On the upper surface of the pinch there is located a shield 41 whose purpose is to prevent light refracted by the distorted portion of the bulb 32 from reaching the reflector. The shield clips around the pinch by means of lugs (42a, Fig. 4, not shown). A shield 46 is located in front of bulb 32 to prevent light issuing from the lamp without first being reflected.
