A cutting means is employed which consists of an upper cutting knife (8) which slides in a direction orthogonal to the direction of travel of roving (2) being conveyed, and a lower cutting knife (12) which is fixed. The upper and lowercutting knives (8) and (12) are provided with openings (9) and (13), (14), respectively which allow the conveyed roving (2) to pass.
Patent GB-845825-A (GB)
Abstract: 845,825. Multiplying-machines. OLIVETTI & CIE S.p.A. ING., C. Sept. 23, 1958 [Sept. 28, 1957], No. 30355/58. Addition to 787,893. Class 106 (1). In a machine for performing short - cut multiplication automatically and having a multiplier register comprising elements each with two series of steps corresponding to multiplier digits associated with direct and shortcut multiplication respectively, the elements being sensed sequentially, the sensing-device is moved one step along the steps after a series of subtract (short-cut) cycles so that the next multiplier digit to be sensed is increased by one. The embodiment described is a modification of the machine described in the parent Specification, in which a sensing slide 159 senses steps 155 (digits 1-4) and 156 (digits 5-9) in multiplier register slides 32. A projection 197 of the operative slide 32 is sensed by a second slide 199 to determine whether addition, subtraction or non-addition is to be performed, and a third slide 221 senses the projection 197 to determine whether or not a unit is to be added to the next higher order multiplier digit. In the present arrangement, the slide 221 is positioned to the right of the slide 32 being sensed and if the operative multiplier slide is in any of its " 5 " to " 9 " positions, the end 226 of the slide 221 when in its forward dotted line position will be alongside the projection 197. Then, when the sensing carriage 122 is step-shifted to the next higher order, the slide 221 will engage that projection and its end 226 will be moved to the right relative to the carriage. This movement rocks a lever 359 and raises a plate 351 in which are guided the sensing slide 159 and a plate 354 carried by the second sensing slide 199. The slide 159 is thus caused to sense the next higher step of the next multiplier slide 32 to add one to that multiplier digit. Moreover, the sensing ends 352, 358 of the second slide 199 are also raised so as to cause addition, subtraction or non-addition as though the multiplier digit had been increased by one. The slide 199 itself has a sensing-end 352 which has the effect of causing addition when the multiplier digit has effectively been increased from four to five. Thus, in these circumstances, the multiplication by five is direct and not by the short-cut method as is normal. During the last of each series of cycles, a bail 164 momentarily shifts the slide 221 to the rear so as to enable it to escape past a projection 197 which has shifted it laterally.

Title: Self regulating transmission
Inventor: STIDWORTHY FREDERICK MICHAEL
IPC: F16H37/10
Filed: 1985-05-15
Abstract: A self-regulating transmission comprises an input and an output differential (11, 12) and a lower ratio gearing (13) and a higher ratio gearing (14) providing drive therebetween. The lower ratio gearing (13) drives bevel pinion (32) in the opposite rotational direction to that of the carrier (27) driven by the higher ratio gearing (14) which rotates in the same direction as that of the output shaft (34). When drive commences initially through the lower ratio gearing (13) the worm and wheel assembly (50, 51) in the higher ratio gearing (14) is adapted so as to resist feedback torque experienced in that gearing and to provide to the carrier (27) a driving force in the required rotation direction of the output shaft (34). This produces a driving force causing the output shaft (34) to rotate as well as a feedback torque in the lower ratio gearing which is sensed at the input differential (11) causing a corresponding adjustment of the rotational speeds of the lower ratio gearing (13) and the higher ratio gearing (14) driven thereby. In an alternative embodiment (Fig. 4), planetary gearing with internal ring gears replaces the bevel gear differentials. <IMAGE>

Title: Crystal puffing
Inventor: SUZUKI TOSHIHIKO
IPC: C30B15/14
Filed: 1985-08-16
Abstract: To increase monocrystal growing speed, it is necessary to increase temperature gradient (dT/dX) within the solid-phase monocrystal at the solid- liquid interface. Since drawn-up monocrystal is always heated by the radiation heat from the heat generator, it is preferable to reduce the temperature of the heat generator. However, where the temperature of the heat generator is reduced, there exists a problem in that the surface of the melted liquid is readily solidified at the position where the liquid adjoins to the inner wall of the crucible. To overcome the above problem, the heat generator is so constructed that the upper portion of the melted liquid is heated to a higher temperature as compared with the lower portion of the melted liquid. <IMAGE>

Abstract: In a vehicular hydraulic brake system, a tandem brake master cylinder (1) is actuable by a hydraulic brake power booster (2) and is connected to wheel brake cylinders of left (VL) and right front-wheel brakes (VL VR) via brake lines (29, 30) containing anti-lock solenoid valves (34, 35, 37, 38). In order to supply the wheel brake cylinders with pressure fluid from the servo- energy supply system (10) during anti-lock operation and to keep the tandem master brake cylinder (1) in an alert position, inlet valves (31, 32) are provided in the brake lines (29, 30), each operating piston (48) thereof being switchable, to open a valve (60, 61), by means of the pressure introduced from the booster chamber (17) via an anti-lock control valve (42), in which said alert position the outlets of the brake lines (29, 30) from the tandem master brake cylinder (1) are closed and the brake lines (29, 30) are connected downstream of the valves (31, 32) with the booster chamber (17). To enable anti-lock control even on failure of one brake circuit, the inlet valves (31, 32) have identical operating pistons (47) which, in the absence of pressure in the brake line (29, 30), remain in the retracted position and consequently prevent the valves (60, 61) from opening and connecting the booster chamber (17). <IMAGE>

Title: Fuel bucket for a liquid metal cooled nuclear reactor
Inventor: WEBB JOHN
IPC: G21C19/06
Filed: 1987-04-06
Abstract: A fuel bucket (10), for use in the removal of nuclear reactor fuel sub- assemblies from under-sodium immersion, incorporates a syphon system for preventing spillage of sodium as the bucket and sub- assembly are raised above the sodium. Such spillage may, in the absence of the syphon, occur because of volumetric expansion of the sodium in response to temperature rise as the bucket (10) emerges from immersion in sodium and is therefore no longer subject to cooling by conduction. The syphon comprises a sleeve (26) and an inner wall (16) defining an annular passage which at its lower end opens into the bucket interior passage and which at its upper end communicates with an annular drainage passage defined by inner and outer walls (16, 18), the lower end of the drainage passage having outlets (22) from which the excess sodium can be discharged by syphon action during raising of the bucket out of the sodium pool. <IMAGE>
