Patent GB-1033585-A (GB)
Title: Spinning or twisting spindle with a dead spindle shank
IPC: D01H7/06
Filed: 1965-05-06
Abstract: One apparatus of the parent Specification is modified in that the driving-member connected to the lower rotatable member 11 which supports the bobbin sleeve is rotatably mounted at its outer periphery, so that the drive can be applied at a level below the spindle-rail.  On Fig. 1, (not shown), an interchangeable whorl 7 below the rail 2 is secured to a sleeve 8 secured to the member 11 and mounted on bearings 10 in a housing 6 fixed to the rail. The member 11 has a downward cup-like extension 12 on which a bunch may be wound at the drifting-stage, and which serves to protect the bearings.  A brake-nut 4 and its operating handle may also be provided below the rail.  The sleeve 6 serves with the blade 18 to provide the adjustment for sleeves of different lengths.  In Fig.2 (not shown), the rail is of box-form and houses a driving-pinion engaging a worm on the sleeve 8; in Fig. 3 (not shown), the sleeve 8 runs in bearings in annular members set in the upper and lower rail-members and is driven by a belt from a driving-pulley.  The sleeve 6 is inside the sleeve 8, and the adjustment is provided as in Fig. 1 of the parent Specification; the sleeve 8 may connect with or form the shape of an electric motor.

Title: Improvements in or relating to speed control circuits for electric motors
IPC: H02P7/288
Filed: 1965-05-06
Abstract: 1,048,705. Automatic speed control. PRESNA MECHANIKA, NARODNI PODNIK. May 6, 1965 [May 7, 1964], No. 19120/65. Heading G3R. When change-over switch P4 is adjusted to position 1, a low voltage is applied to the emitter of transistor T1 which is rendered conductive together with the transistor T2, whereby motor M is started. Centrifugal contact P1 opens when the speed reaches a predetermined value, so that the base-potential of the transistor T1 drops. The transistors T1, T2, are rendered non-conductive to include resistor R11 in series with the motor whose speed decreases until contact P1 is reclosed. By repeating this operation the speed of the motor is maintained at a predetermined level. Higher levels of speed are provided by adjusting the switch P4 to the positions 2 and 3. In another arrangement, voltage divider R1-R4 is in the emitter circuit of transistor T1 whilst voltage divider R6-R9 is in the base circuit of that transistor.

Abstract: 667,208. Valve generating circuits; frequency modulation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 20, 1949 [July 29, 1948], No. 19158/49. Classes 40 (v) and 40 (vi). A travelling wave valve oscillator has a band-pass filter F in its feed-back path the width of which is less than the frequency difference of two adjacent modes of operation. This permits the anode voltage to be adjusted or modulated to vary or modulate the frequency of operation, over a frequency range equal to the width of the filter without the mode of operation changing. A phase shifter D may be included in the feed-back path to adjust the circuit so that only one mode is included when the desired operating potentials are applied.

Title: Improved type bar mechanism for typewriters
IPC: B41J7/02
Filed: 1936-07-14
Abstract: 468,101. Typewriters. LEVI, R. July 14,1936, No. 19570. [Class 100 (iv)] Type-lever actions.-The typeheads are pivoted to the type-levers on axes corresponding in position to the bends of ordinary type-levers, and are automatically turned into the vertical position when the type-levers are swung. The arrangement enables the type-levers to be closely and uniformly spaced in the segment of a portable machine. In the mechanism shown in Figs. 3 and 5, a short type-lever 1, pivoted on a wire 2 in a segment 13, is provided with a pin 3 carrying pivotally a type-head 5 which normally lies in the plane of the type-lever. The type-head is connected by a link 9 to a slide 11 mounted on the type-lever and guided by a slot 12 therein. A pin 19 on the slide engages a cam-slot 54 or fork in a bellcrank 52 pivoted on the type-lever and provided with a pin 18 which is yieldingly connected by a spring 21 to a link 15 pivoted on a wire 14. When the type-lever is swung, the linkage 15 .. 9 rotates the type-head, and immediately before impression the type-head occupies the vertical position and rotation therefore is arrested by engagement of the slide 11 with an adjustable stop 20. The linkage causes the type-head to rotate slowly at the beginning of the movement, time being thereby provided for the type-head to clear the adjacent type-heads. To provide for graded increase in the arcs of rotation of the type-heads from the middle to the sides of the system of type-levers, the pivots 16 of the bell-cranks 17 are placed progressively further from the pins 19. A suitable noiseless action for the type-levers comprises a key-lever 28 connected by a link 32 to a bell-crank 34 having pin-and-slot engagement 39, 41 with a bell-crank 38 which is connected by a link 42 to a pin 44 on the associated typelever. The pin 44 may be arranged mid-way between the small and capital types on the typehead, or opposite one of the types. The bellcrank 38 is connected by a link 45, provided with a weight 50, to bell-crank 48 in connection with a spring 53. The bell-cranks 34 are graded in length and are pivoted on a straight wire 35, and the bell-cranks 38, 48 are of uniform lengths and are pivoted on curved wires 40, 49. The bell-cranks 34 have uniform movements and impart uniform movements to the bell-cranks 38. On depression of the key-lever, toggles constituted by the links 42, 45 and the bellcranks 38, 48 approach the straight position, and the weight 50 gains momentum and then completes the straightening of the toggles to effect impression. The toggle constituted by the link 32 and bell-crank 34 also is straightened. The bell-cranks 34 co-operate with a straight universal-bar 36. Aligning for impression.-The type-head 5 and aligning-guide are provided with co-operating horizontal surfaces for counteracting the tendency of the type-head to twist about an horizontal axis during impression. Preferably, the type-head is provided with a groove 24 and pin 23 for engaging a rib and recess on the aligning-guide.

Title: Improvements in or relating to a process for making rubber thread
IPC: B29D99/00
Filed: 1933-07-11
Abstract: Rubber thread is made by streaming a coagulant into a body of latex, and continuously withdrawing the filamentary coagulum thus formed. Usual coagulants, such as acetic or formic acids, or alcohol may be used, and these may be thickened by the addition e.g. of cellulose acetate, gums, or resins.  Heat sensitive latex may be employed, and a hot coagulant streamed into it.  On emerging from the bath the surface of the thread is preferably hardened by treatment with a coagulant.  The thickness of the p  thread depends on the size of the nozzle, nature of the coagulant, rate of flow, length of bath, speed of withdrawal of the thread. Vulcanized latex may be used, or the thread may be subsequently vulcanized.  Specifications 214,615, 290,313, 307,315, and 311,844, [all in Class 70, Indiarubber &c.], are referred to.

[Class 83 (i)] - A chaplet comprises two nipples connected by an elastic device, one nipple 9 being fixed in the core or core-bar 4, the other 10 being of the same metal as that cast and being surrounded by an annulus 11 made of a metal which melts at a temperature between that of the preheated mould 2 and of the cast metal 5. The elastic device may consist of conical discs, 7, 8, the latter being integral with the nipple 9 and the former holding 10 by friction. The mould shown is for centrifugal casting and the bar 4 supports end cores, not shown, which make contact with the cast metal. When the chaplet is used in a fixed mould the elastic device 8 is located in a recess in the core.
