Title: Improvements in hydraulic boosters
IPC: B60T13/16
Filed: 1967-05-10
Abstract: 1,124,417. Hydraulic apparatus. ALFRED TEVES MASCHINEN - UND ARMATUREN FABRIK K.C. May 10, 1967 [Aug. 26, 1966], No.21773/67. Heading F1P. Pressurization of liquid within a chamber 2 having a connection C to a device to be supplied and bounded by one side of a piston head 3a is effected by adjusting the other side of the piston to the delivery pressure of a pump (not shown) and this latter pressure is controlled by manual axial displacement of a throttle cone 7 within the hollow stem 3b of the piston in relation to a seat 8 located between axial spaced radial bores 5, 5a, 6, 6a in the stem 3b which serve to connect the pump delivery connection A to a return connection B. The cone 7 itself houses a needle valve 19 past which air bled from chamber 2 through a piston head bore 18 passes through the open throttle and bores 6, 6a to the return connection B; pressure on opposite sides of the piston head being equalized through a floating ball valve 16. In operation and on pushing against an insert valve member 11 the needle valve is seated and the pressure between cone 7 and its seat 8 is restricted thereby allowing a build-up of pressure which seats ball 16 at 14 and displaces piston to the left thus pressurizing liquid in chamber 2. On retracting the cone 7 pump delivery pressure is relieved through the throttle and connection B and the piston head 3a is returned by a spring 25 to abut a stop pin 12.

Title: Improvements in and relating to picking-motions of looms for weaving
IPC: D03D49/46
Filed: 1927-08-18
Abstract: 293,589. Mutter, K. Aug. 18, 1927. Picking-motions; shuttles. - Relates to picking-motions of the kind in which shuttle housings or boxes move simultaneously towards and from the centre of the lay and transfer the shuttle by inertia from one housing to the other, and consists in the provision of pusher devices in the boxes to follow or push the shuttle during transfer when the box with the shuttle moves inwardly, the pusher returning to its normal position and remaining there when a box moves inwardly without a. shuttle. The shuttle housings 2, 3, Figs. 1, 2 and 5, are mounted on carriers 5 provided with rollers 7 movable on guide rods 8, 9 on the lay. The carriers 5 are reciprocated towards and from the centre of the shed by camoperated levers 46. When the carriers approach the centre of the shed, the shuttle 1 normally held within the open end of the housing 2 by a spring catch 47, is released by the action of a pusher 31 movable in the housing against an incline 45 on the catch. The pushers are operated by forks 49, 50 adapted to engage cam-controlled stops 34 and serve also to transfer the shuttle positively from one housing to the other when the inertia of the shuttle, owing to the low speed of the loom, is unable to effect the transference. The upper parts of the housings are provided with apertures 30 through which a shuttle bobbin may be removed for replenishment. In some cases, the carriers for the housings are guided on a single guide rod. The beginning of the transfer of the shuttle from one housing to another is effected while the lay is at rest. In a modification, the pusher and the catch for holding the shuttle are controlled by two rods moving with the housing and connected to bell-crank levers movable along bars, cam-controlled stops at the inner end of the bars causing the operation of the pusher and catch for effecting the transfer of the shuttle from one housing to the other. Beat-up motions.-The connecting-rods 17, Fig. 2 and 3, are slotted to receive the shaft 14 of cams 12, 13 which engages projections 15, 16 respectively on the connecting-rods.

Abstract: 672,672. Glass-to-metal seals. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 7, 1950 [Sept. 10, 1949], No. 22058/50. Drawings to Specification. Class 36. [Also in Group XL (a)] Sealing of the glass window of a cathode-ray tube to the open end of a metallic conical envelope is effected by placing the window on top of the cone when inverted and progressively heating the cone by a high-frequency coil surrounding it and slowly raised to the wide end of the cone so that the glass is uniformly heated by radiation from the cone and by heat radiated or reflected from a metal or insulating screen surmounting it, sealing of the glass to the cone taking place when the coil reaches the top edge of the cone. Alternatively the cone may be lowered through the coil. The upper side of the screen may be reflecting to reduce radiation, may be heated by a burner and rotated, and may be slotted to avoid induced heating by the coil. The cone is held in a holder and may be open at the base and receive a plug admitting an inert gas under pressure into the cone to keep the window floating at its molten edge. The coil may. be gradually lowered after sealing to allow cooling, or the tube uniformly cooled down in a furnace. A glass tube carrying the electrode assembly is finally sealed to the narrow end of the cone.

Title: Method and apparatus for processing synthetic yarns
IPC: D02G1/00
Filed: 1974-05-17
Abstract: 1431137 Crimping yarns PHILLIPS PETROLEUM CO 17 May 1974 [24 May 1973] 22063/74 Heading DIF A synthetic filament yarn 4 is processed by successively crimping the yarn, entangling, i.e. interlacing, the crimped yarn, and thereafter heating the entangled yarn whilst under tension thereby to produce a straightened yarn which, after cooling, will resume a crimped form upon subsequent heating in a relaxed state. As shown in Fig. 1, continuous filament draws synthetic yarns 2 are fed from packages 1 through eyelets 6 and tensioning gates 7 to a guide 9 to form a yarn 4 of the desired total denier. The yarn 4 passes through a tensioning gate 8 and around a heated feed roll 10 to a crimping means 16 comprising a fluid jet portion and a chamber containing stacked balls 15. A heated fluid enters through an inlet 17 and exits through an outlet 19 and through the balls 15. Prior to crimping, an adjustable angle idler 18 inserts a controllable amount of false twist into the yarn. The yarn plug 20 formed in the means 16 is passed through a tube 22 which is angled, as shown, or straight, which may have a polytetrafluoroethylene lining, and in which the plug 20 is broken up and cooled by countercurrent fluid 23, e.g. air. A photoelectric eye 27 comprises a photoelectric cell positioned to one side of the top of the plug 20 and a light source positioned on the other side of the plug level with the cell, the light beam 27a being directed through openings 21 in the tube 22. When the yarn plug height 25 breaks the beam 27a, a temperature controller 31 acts to raise the temperature of the feed roll 10 to decrease the yarn plug length. When the height 25 falls below the beam 27a, the controller 31 maintains the temperature of the roll 10 at a level so that the height 25 is maintained just below the beam 27a. The crimped yarn 4 is tensioned by pins 28, passes through an entangler 30, over a guide 34, over a withdrawal roll 36, through a heater 38 having fluid inlets 39a and outlets 39b, and over a guide 42 to a constant tension winder 40. As the yarn passes through the heater 38 it is exposed to a high tension relative to that in the entangling zone 32 to effect straightening thereof. In a modification, Fig. 2 (not shown), undrawn or partially drawn yarn is used and a heated draw roll (12) immediately follows the feed roll (10). The height of the yarn is controlled by controlling the temperature of either the draw roll (12) or the feed roll (10). In other modifications (not shown), the photoelectric eye is replaced by a mechanical sensing device or by a combination of electrical and mechanical sensing devices. In a further modification (not shown), two temperature controllers are used, the second having a set temperature point higher than the first, the photoelectric eye being switchable from one to the other. The yarn may be polyamide, e.g. nylon 66 or trilobal nylon 6, polyester or polyolefin, e.g. polypropylene. In processing nylon, moisture is applied during straightening, e.g. by saturated steam.

Abstract: 762,867. Transistor pulse circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 15, 1954 [Aug. 14, 1953], No. 22413/53. Class 40(6) A load 21 is fed over a first transistor 20 and diode 22 and a second transistor 23 is arranged so that its emitter-base cirucuit shunts the diode and its emitter-collector circuit shunts the load. The waveform appearing across the capacitative load 21 follows closely the rectangular input waveform. A negative signal applied to the base of transistor 20 causes it to conduct and pass current to the load, the potential drop across diode 22 maintaining transistor 23 cut off. Assuming the load to be capacitative, when the base potential 20 is raised the transistor is cut off, the base potential of transistor 23 falling sufficiently for it to conduct and the load 21 discharges through the emitter-collector circuit. Since the transistor 20 is cut off, only the residual collector current flows and this must equal the base current of transistor 23 plus the current in resistor 28. The base current is thus very small and the transistor 23 operates with substantially equal emitter and collector currents. The resistor 28 may be omitted if the residual collector current of transistor 20 is not greater than that of transistor 23. Specification 762,868 is referred to.
