Title: Device for applying stacked travellers onto the rings of ring spinning frames
IPC: D01H17/02
Filed: 1957-12-09
Abstract: 859,273. Applying travellers to spinning frame rings. BACKER A. G. Dec. 9, 1957 [Dec. 8, 1956], No. 38171/57. Class 120(3). In a device for applying stacked travellers to the rings of spinning frames, in which the foremost of a stock of travellers 21 spring pressed against stop 25 is separated by a tongue 7 and pressed thereby on to a ring 5, Figs. 6, 7, the spring pressure is exerted through a sleeve 15, Fig. 2, sliding on a tube 14 parallel to a guide rod 22 carrying the stacked travellers, and the stop 25 is fixed to tongue 7. Pressure is exerted on sleeve 15 by a spring 19 which bears on a block 18 displaceable within tube 14 and connected to sleeve 15 by a screw passing through a slot 16 in the tube. A lug 24, Fig. 1, on sleeve 15 presses against the rear of the stack of travellers on rod 22 which is connected to tube 14 by a strap 23. Tube 14 is carried by a plate 3 fixed between two handle parts 1, 2. Tongue 7 is slidable within the handle 1, 2 and is advanced against the tension of a spring 12 by raising an operating handle 9. Stop 25 is adjustable transversely of the direction of movement of tongue 7, to suit the width of traveller, by an adjusting screw 27, a spring-loaded ball engages notches in the surface of the screw to retain the screw in its adjusted position. The end 26 of rod 22 projects slightly beyond plate 3, so as to retain the end traveller, and is chamfered on the side facing tongue 7 which is pressed resiliently against plate 3 by a leaf spring so as to be able to ride over the rod end. In operation, a recess 4 in plate 3 is set against the edge of the ring 5, Fig. 6. Handle 9 is raised to advance tongue 7 horizontally as a pin 32 on tongue 7 slides in a slot 33 in plate 3. As pin 32 enters the inclined portion of slot 33, the front end of tongue 7 moves upwardly, so that a projection 31 causes the detached traveller 21 to make a quarter turn on to the ring, as in Fig. 7. An eccentric 35, Fig. 1, can be turned to adjust the position of rest of tongue 7 to suit the traveller thickness. In a modification the whole path of movement of the front of tongue 7 can be adjusted relative to the ring 5. To apply a new stock of travellers to rod 22, sleeve 15 is drawn back and turned so that the guide screw engages a notch 36, Fig. 2, in the end of slot 16; lug 24 is thereby moved clear of the free end of rod 22. A small knife at the end of rod 22 serves to cut the wrapping as a wrapped stack of travellers is pushed on to the rod. In another modification, Fig. 12, a two-part traveller guide is provided, the rear part 37 being detachably held between the front part 38 and a holder 39 and being exchangeable for a similar part serving as a magazine on which a stock of travellers has been arranged.

Title: Improvements in or relating to counter weighing scales
IPC: G01G23/02
Filed: 1928-12-29
Abstract: 327,176. Avery, Ltd., W. & T., and Sykes, C. M. Dec. 29, 1928. Counter scales; compound-lever apparatus; pendulum-weight apparatus; relieving and locking mechanism.-In a counter weighing-scale, the lever system, and the automatic weight-indicating mechanism, where such is employed, are locked automatically against movement when the scale is lifted. As applied to a weighing scale of the kind described in Specification 224,375, the locking arrangements, Fig. 1, comprise levers 10 pivoted on supports 11, springs 13 tending to turn the levers, plungers 8 slidable through the base feet 6 and a rod 16, the lower end of which is out of contact with the weighbeam 9 in the weighing position. When the scale is raised from the counter the springs 13 turn the levers 10 so as to push the plungers 8 through the feet 6 as shown and cause the upper ends of the plungers to clamp the hooked ends 9<a> of the weighbeam. Projections 10<a> on the levers 10 engage the lowermost levers 12 of the lever system and raise them so as to carry upwards the levers 14 and weighbeam 9, thus removing the main knife-edges from their bearing blocks as shown. The upward movement of the weighbeam raises the rod 16 and brings the serrated end of a lever 18 into contact with a V-shaped projection 19<a> on the pendulous resistant, thus lifting the pendulous resistant and bringing its knife-edge 21 into abutment with hooded caps 22, thereby completely locking the weighing system. When the scale is again deposited on the counter the plungers 8 are thrust in and the various parts are automatically restored to the weighing position. By screwing out the feet 6 the locking mechanism may be brought into action when the scale is resting on the counter. In a modification, Fig. 5, the rods 8 are provided with pistons 8a slidable in cylinders formed in the feet. In a. further modification wherein the plungers 8 are dispensed with, the base plate of the scale carries a pair of levers 23, Fig. 3, fitted at the ends with rollers. When the scale is raised from the counter the levers rotate under the action of springs into the position shown and raise the pan supports 25, together with the lowermost levers to which the pan supports are attached. The lowermost levers in rising lift the intermediate levers and the weighbeam, the end knife-edges of the weighbeam being engaged by hooded caps carried by the lowermost levers.

Title: Voltage regulator and overload protection system
IPC: G05F1/573
Filed: 1960-11-09
Abstract: 906,480. Automatic voltage control systems. AVCO CORPORATION. Nov. 9, 1960 [Nov. 13, 1959], No. 38560/60. Class 38 (4). [Also in Group XL (c)] A voltage regulator of the series transistor type comprises a series power transistor 17, a second transistor 28 having its base coupled to an output voltage sensing circuit which includes a potentiometer 22 and having its emitter connected to a source of constant potential including a Zener diode 31, the output at the collector of transistor 28 being responsive to the deviations of the output voltage from a value predetermined by the setting of potentiometer 22, and a third transistor 37 coupling the collector of transistor 28 to the base of power transistor 17 so that the voltage drop between the emitter and collector of the power transistor is varied in response to output voltage deviations whereby the output voltage is maintained constant. A thermistor 41 and load current-sensitive diode 15 serially coupled between the base and emitter of transistor 17 respectively stabilize the output voltage with respect to ambient temperature variations and internal operating temperature variations of the power transistor. Overload protection is provided by a circuit including voltage divider resistors 44, 45 shunted across the input terminals 10, 11 and a diode 46 connected between the junction of resistors 44, 45 and the collector of transistor 17, the arrangement being such that the diode 46 is non-conducting during normal operation but becomes conducting on an overload, whereby transistors 28, 36 and 17 are rendered non-conductive and the diode 46 together with resistor 44 serves as a load across the input terminals; on removal of the overload, the diode 46 still conducts so it provides a voltage across the output terminals 12, 13 and the transistors 28, 36 and 17 are biased into conduction whereby the diode 46 again becomes non-conducting and the regulator resumes normal operation. Diodes 24, 25 in the output voltage sensing circuit protect the transistors 28, 36 and 17 should the voltage across resistor 22 rise excessively, e.g. during starting.

Abstract: 1,182,715. Aircraft undercarriages. H. R. STRATFORD. 31 July, 1968 [22 Aug., 1967], No. 38698/67. Heading B7G. An aircraft undercarriage comprises an upper support structure 10 which is pivotable about an axis 22, and a bogie structure 13 attached to the support structure 10 by a pivot pin 12 and supporting two pairs of wheels 15, 16. A first bogie arm 30 carries the forward pair of wheels 15 on an axle 31; a second bogie arm 32 carries the rearward pair of wheels 16 on an axle 39, and is formed integrally with the cylinder 34 of a shock absorber 35, the piston 36 of which is movable along an axis 38 and is pivotally connected via an arm 41 to the first bogie arm 30 at 42. A compressive spring box 52 is pivotally connected between arm 30 and structure 10 to bias the rear wheels downwardly during touchdown. The spring box also minimizes motion of the bogie arms when the wheel brakes are applied to stop the wheels rotating after take-off; a chain or other flexible inextensible means could be used to perform the first of these two functions of the spring box. Conventional brake compensating links 55, 56 are provided. On landing, the axles 31 and 39 are initially in positions 46 and 47, impact with the ground being absorbed and resulting in the configuration shown. On take-off the undercarriage is retracted sideways. The shock absorber may be of an oleo-hydraulic, liquid compression, solid elastomer or other type; the arms 30, 32 may be inverted so that the axis 38 passes below the pivot 12, in which case the shock absorber would be in tension. The second bogie arm may be pivoted to the first bogie arm at a point other than the pivotal connection of the first bogie arm to the support structure 10.

Title: Improvements in or relating to sprinkler type fire fighting installations
Inventor: TAYLOR JOHN NOEL
IPC: A62C35/60
Filed: 1963-10-03
Abstract: 1,083,456. Accelerator for sprinkler systems. MATHER & PLATT Ltd. Sept. 30, 1964 [Oct. 3, 1963], No. 38927/63. Heading A5A. A latch-operated main control valve 1 in a sprinkler system is operated by movement of a diaphragm 6 cooperating with the latch 4 by means of the plunger 5. The said diaphragm is contained in a chamber 13, one side of which is connected to the interior of the system via pipe 19. A float chamber 15 is connected through pipework 16 to a 3-way valve 17 (used for testing), to the "front" side 19 of the diaphragm and, through a restrictor (e.g. a porous plug 20) to an air bottle. In the bottom of the float chamber is a well 25, across which is stretched a diaphragm 26, on which rests a button 27 formed on the under surface of a float 28 pivotally secured to the chamber by the resilient strip 29. The well 25 is connected to the air bottle on the bottle side of the restrictor so that, in the steady state, there is no pressure differential across the diaphragm 26 and the float depresses it. The float 28 also carries a seating 31 which blocks a passage 32 between the float chamber 15 and the back side 33 of the latch-operating diaphragm 6. A rapid drop in pressure within the system (caused e.g. by operation of a sprinkler head) creates a pressure differential across the diaphragm 6, which lifts the float 28 and opens the passage 32, thus counteracting the installation pressure on the front side of diaphragm 6 and a spring 34 causes operation of the plunger 5, latch 4 and the main control valve. On the other hand, slow pressure variations within the system do not cause the system to operate, since the reference pressure in bottle 21 can also alter slowly. Similarly, slight leaks past valve 1 causes the float 28 to rise, thus opening the passage 32 to allow water to drain into chamber 33, whence it passes through a water drain valve 36 back to the main inlet, but more serious leaks cause the float 28 to rise sufficiently to operate latch 4 to release a seal 3 to allow water to pass into the alarm groove 7 and thence to an alarm system 11.

Title: Optical fibre connector
IPC: G02B6/32
Filed: 1977-09-19
Abstract: An optical fibre (14) is coupled to a light-emitting device, e.g. another optical fibre (13), via a light-transmitting element (17). In order to accommodate the end of the optical fibre (14), the light-transmitting element (17) has a cavity (38) bounded by a surface of revolution (40). Arranged between the surface of revolution (40) and a plane end face (50), perpendicular to the axis, of the optical fibre (14) is a liquid optical material (51) whose refractive index differs from that of the light-transmitting element (17) with the result that the optical material (51) acts as a lens. The device is simple and inexpensive to produce and permits a substantially better coupling efficiency than known devices, in which, for example, two optical fibres are simply held end to end. <IMAGE>

Abstract: 1422748 Counting particles; correcting counts CONTRAVES AG 20 Aug 1973 [15 Sept 1972] 39243/73 Heading G4D In a counting apparatus for determining the concentration of particles in an electrically conducting liquid extra pulses are fed to the counter according to a predetermined function of the accumulated count to compensate for errors, e.g. due to overlapping particles. A predetermined quantity of the conducting liquid is passed through a capillary restriction in a cell MZ; the low conductivity particles produce resistance fluctuations in the cell which are converted to pulses a. A bi-stable US 1  diverts half the pulses b to an OR-gate T 2  and intervening pulses to a variable divider US 2  which delivers a proportion of the pulses c via an AND-gate T 1  to the OR-gate T 2 . The pulses b + c are accumulated in counter ZW and the count in the highest order Z 3  controls a function generator FG which adjusts the ratio of the frequency divider US 2  such that a greater proportion of pulses c are delivered as the accumulated count increases. This corrects for the statistically higher chance of overlapping particles at higher concentrations.
