Title: Improvements in or relating to lead-through insulators
IPC: H01B17/28
Filed: 1928-01-11
Abstract: 309,472. Pollak, J. E., (Hermsdorf- Schomburg-Isolatoren Gas.). Jan. 11, 1928. Insulators.-In order to prevent or to reduce the formation of corona. a lead-in insulator has the outer electrode made in the form of a collar or girdle, and its surface is so shaped that the electric field between it and the inner electrode is substantially uniform. It is also arranged to project from the porcelain. or other insulating body, towards the inner electrode to such an extent that the porcelain remains wholly outside the strong electric field. Further, the insulating body engages the inner electrode, and preferably the outer electrode. at places where there is a constriction. The inner electrode 1, Fig. 1, is of the known shape in which the part that is surrounded by the outer electrode 2 is a neck between two enlarged portions. The outer electrode presents a rounded surface towards this neck, so that a substantially uniform field is formed between the electrodes. The porcelain shell 3 of the insulator is connected, as shown, so that it is outside the strong field between the electrodes. The inner electrode need not be formed with a neck but may be formed as a cylinder or as a rod i, Fig. 2, with spherically enlarged ends e. Spheres a are also fitted to the rod i outside the insulating shell k, and these spheres may be hollow so as to cover parts, such as springs f or securing-nuts m, which would favour the formation of corona. In this construction, a conducting collar w is mounted on the outer electrode o outside the insulating shell k. Thus constructions are formed on the electrodes in which the shell terminates, and the electric field at these points is weaker.

Title: Improvements in or relating to automatic craft control systems
IPC: G05D1/08
Filed: 1952-01-15
Abstract: 707,932. Automatic steering control systems. BENDIX AVIATION CORPORATION. Jan. 15, 1952 [March 10, 1951], No. 1179/52. Class 38(4) In a system for automatically controlling a craft about one of its axes in response to rate of change of attitude of the craft about that axis, such response is varied as a function of altitude. As shown a gyroscope 6 responsive to change of altitude of a craft about one of its axes is associated with the rotor 3 of an inductive pick-off 1 the stator 5 of which applies, according to the sense of attitude deviation, an A.C. signal of one phase or the other to an amplifier triode valve 9. One or other of two triode valves 13, 15 is thus rendered conductive to saturate, through a winding 19 or 21, one or other of two transformers, the secondary windings 27, 29 of which are connected in opposition to supply a normally de-energized winding 31 of a two-phase servomotor 33. Servomotor 33 thereupon runs in the appropriate direction to correct attitude by adjustment of a control surface 39. An inductive device 40 operated by servomotor 33 produces a follow-up signal and an inductive device 45 associated with a gyro 48 responsive to rate of change of attitude produces a rate signal. These signals are applied to the input of valve 9 from stators 43 and 49 respectively. To increase the rate signal with increase of altitude so as to maintain constant the total damping of the craft, a device 57 responsive to barometric pressure is associated with an inductive device 51 controlling the voltage applied from an A.C. source S to the rotor 47 of inductive device 45. To increase the deviation signal with increase of altitude and decrease of speed so as to maintain constant the total static stability of the craft, a device 65 responsive to dynamic pressure is associated with an inductive device 64 controlling the voltage applied from an A.C. source S to the rotor 3 of inductive device 1. Rheostats 59 and 67 permit adjustment to obtain the desired response characteristics of the craft.

Title: Improvements in or relating to Withdrawing and Winding Mechanisms for Textile Machines.
IPC: B65H54/52
Filed: 1967-01-11
Abstract: 1,168,703. Break-spinning apparatus; delivery rollers. VYZKUMNY USTAV BAVLNARSKY. 11 Jan., 1967 [23 March, 1966], No. 1427/67. Heading D1D. In mechanism for withdrawing and winding-up the yarn in break-spinning apparatus, the rotation of which mechanism can be reversed for repriming the apparatus in the event of a break in the withdrawn yarn, the winding mechanism comprising a traversedrum, and the withdrawing mechanism comprising a pair of nip roilers, one of which is driven and the other is a pressure-roller, the pressure-roller is mounted so that it can be lifted off the driven roller; to this end, it engages a working-member which is controlled by a device according to the direction of rotation of the traverse-drum, so that during the reverse rotation of the latter for re-priming, the withdrawing rollers are spaced apart. In Fig. 1, yarn 2 is withdrawn from the spinning-chamber 1 by nip rollers 3, 4 to be wound on a package 9 under the control of a traverse-drum 8. The roller is driven by the drum 8 which is itself driven by a motor 17. The roller 4 is mounted on a pivoted arm 5. The presence of yarn between the chamber and the nip-rollers is sensed at 15, and the direction of rotation of the roller is sensed at 14. When the yarn breaks, the sensing-device 15 supplies through a device 16, an impulse to the drive 17 causing it to reverse the direction of rotation of the roller 8, and accordingly of roller 3. When the drive 14 senses the reversal, a device 13 supplies an impulse to a member 11 which causes the arm 5 to pivot and raise the roller 4. In Fig. 2, the pressure-roller 4 is. carried by an arm 20 pivoted at 6. The driven roller 3 is keyed to a shaft 18, Fig. 3, and when the direction of rotation is reversed it displaces a cam 33 to pivot the arm 20 and raise the roller 4. The inside of the roller is hollow and provides a hub 22 with a profiled surface 23 cooperating with rollers 24 to form a one-way clutch between the roller and a ring 28 with a friction-pad 32 urged against a cam 33 by a spring 31. During the spinning operation, as the roller 3 is. rotated to withdraw the yarn, the clutch is disengaged, and the cam tends to rotate in direction opposite to that in which the roller is rotated under the influence of a spring 36 secured at one end to the cam and at the other to a fixed part 38. This tendency of the cam to rotate is restrained by the engagement of a pin 42 with a face 40 of a recess 39 in the cam. When the roller is backrotated for re-priming, the clutch is engaged and the cam is driven through the ring 30 and pad 32, the rotation of the cam being limited as the opposite face 41 of the recess engages the fixed pin 42. As the cam rotates, a profile 44 thereon engages the arm 20 and causes it to pivot and lift the roller 4.

Title: Improvements in or relating to thermostat devices for refrigerating cabinets or likerefrigerating apparatus
IPC: G05D23/13
Filed: 1929-01-16
Abstract: 308,773. Electrolux, Ltd., (Assignees of Platen-Munters Refrigerating System, Akticbolag). March 30, 1928, [Convention date]. Thermostats. - A thermostatic element 3, Fig. 1, containing a congealable medium such as water is arranged so that a part is in metallic contact with the cold producing or transferring member 6 of a refrigerating cabinet while the remainder is exposed to the air of the cabinet. The force due to change of volume is transmitted through a liquid in a tube 4, preferably made flexible by a loop 5, to a bellows or like chamber 18, Fig. 4, to actuate a cooling-water supply valve, and the flow of cooling-water controls a switch in the driving or heating circuit of the refrigerating apparatus. The element 3 may be set vertically as shown in Fig. 1, or horizontally, as shown in Fig. 3, with its end 8 secured by clamps 7. When set horizontally a perforated tortuous band 9 or other baffle device is inserted in it to prevent movement of the unfrozen liquid. The control is varied by changing the extent of contact of the element with the evaporator. The bellows member 18 contains a spring pressed piston 19 fitted with an inner spring pressed valve member 22 adapted to seat against a nozzle 12 extending from a passage 14 through which cooling-water flows to the refrigerating apparatus. The pressure of the water may be reduced on its way to the refrigerating apparatus, as by passage through perforated baffles 16, Fig. 5. When the thermostat allows the cooling-water to flow the water pressure acts through a diaphragm 28 and rod 32 against the action of a spring 31 to close a, mercury switch 33. A hand operated bye-pass valve 35, Fig. 5., is provided in the cooling-water passage, to cut out the thermostatic control.
