Patent GB-112888-A (GB)
Title: Improvements in or relating to what are known as Quick-acting Vices.
Inventor: SAUNDERS CHARLES ERNEST
IPC: B25B1/12
Filed: 1917-06-02
Abstract: 112,888. Saunders, C. E. June 2, 1917. Vices.-In a quick-action vice of the kind in which a rotatable, and axially movable rack carried by the sliding jaw is normally engaged by a toothed locking- member carried by the fixed jaw and is partially rotated to disengage it from the locking-member to allow of rapid adjustment, the rack is formed with deep teeth of coarse pitch and the locking-member with teeth of different pitch to that of the rack teeth so that the teeth engage with a vernier like action tnereby providing a large number of locking positions while ensuring great strength of the teeth. As shown, the teeth 7 of the rack 6 are normally engaed by one of a number of toothed blocks 10 vertically slidable in a guide 12 of the fixed jaw 9<a>. A spring 21 normally holds the rack in position to be engaged by one or more of the blocks 10 in which position a stop pin 17 on the rack engages one end of a quadrantal stop 19 on the sliding jaw 9. To disengage the rack, it is turned to an extent limited by the engagement of the pin 17 with the other end of the stop 19 by means of a collar 14 loose on the rack and provided with a dog 16 engaging a collar 13 secured to the rack. The collar 14 is turned by a handle 22. After the insertion of the work, the collar 14 is turned in the opposite direction allowing the spring 21 to re-engage the rack after which the action of cam surfaces 15 on the collars 14, 13 causes the rack to move longitudinally to bring the vertical part of one or other of the teeth 7 into engagement with the face of one of the blocks 11, and thereafter tighten the jaw 9 on to the work. Instead of sliding blocks 10, a single block with multiple teeth, or pivoted pawls could be employed, and a spring could be provided for pressing the blocks into engagement with the rack. The cam 15 could also be arranged to co-act with a cam surface on the jaw 9 instead of on the collar 13 or, instead of employing cams, the collar 14 could be screwed upon the rack 6.

Title: Improvements in centrifugal machines
IPC: B04B9/12
Filed: 1927-03-22
Abstract: 279,318. Construction Franþaise d'Appareils de Laiterie, and Minet, A. March 22, 1927. Driving, suspending, balancing.-The spindle of a centrifugal machine is supported during normal running only at its lower end while the upper end is free and maintained in position by gyroscopic action, but it is held by mechanical means when the spindle is at rest or rotating below the critical speed. The spindle 1 of the centrifugal machine is mounted inside the hollow shaft 2 which carries the rotor 3 of the driving electric motor. The stator 11 is supported by the casing and is supplied with current through terminals 12. The lower end of the spindle 1 rests on a pivot 4 supported on the balls of a footstep bearing 6 mounted on a hollow support 7. Above the casing, a bracket 16 is fixed to the spindle and carries a conical ball race 15 arranged opposite a cylindrical or conical race 17. Balls 18 are placed between the two races and are in engages ment with both while the machine speed is low, but they are lifted up the conical race 15 by centrifugal force when the speed is high, so that the spindle and its centrifugal drum operate like a peg-top. In a modification, bell-crank levers are pivoted to the bracket carried by the spindle; their outer arms are weighted and the inner arms rest against the outer race of the upper bearing. Lubricating oil is supplied from a reservoir to the pipe 20 from which it flows up the hollow support 7 through the bearing 6 to the casing and escape pipe 22. In a, modification the casing forms the reservoir, and vanes on the end of the hollow shaft 2 force the oil up to the reservoir. In another modification the hollow shaft 2 rotates round a sleeve 25 held by a pin 26 and placed over a sleeve 27 of resilient material so as not to interfere with the equilibrium of the spindle. A spiral groove in the periphery of the sleeve 25 causes the oil to pass up to the bearing, from which it falls back to the casing through the support 7. The rotor 3 may be mounted for a frictional drive upon a, cylindrical or conical sleeve, the engagement being secured by the weight of the rotor or by spring pressure.

Filed: 1935-03-15
Abstract: 436,839. Directive wireless signalling. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. March 15, 1935, No. 8159. Convention date, Aug. 14, 1934. [Class 40 (v)] Relates to the circuits used for receiving course-marking signals say on 7 metres, and other signals say on 3 metres, in aircraft navigation. According to the invention, both signals are fed to a common low-frequency stage of the receiver, and one only of the rectified signals, namely the marker signal, is used to apply automatic gain control to that signal. The marker signal is received on the aerial A and is rectified at G1. The 3-metre signal is received on the aerial D and is rectified at G2, and combined with the first signal in the input to the low-frequency amplifier N1. The output of the following stage N2 comprises a filter circuit 6, 3, 4, 5 tuned to the note frequency of the 3-metre signal, so that this is filtered out to a separate indicator, whilst the note frequency of the marker or 7-metre wave is filtered out by the circuits 7... 10, and passes to an indicator J. Part of the lowfrequency output from the transformer 11 is rectified at 12 and, after smoothing, is fed back to control the gain of the detector G1 as the distance of the craft from the course-marker beacon alters.

Title: Improvements relating to the preparation of fibrous material for spinning
IPC: D01H5/02
Filed: 1946-03-19
Abstract: 612,529. Preparing fibres for spinning. SCHNEIDER, W. H. March 19, 1946, Nos. 8541 and 16974. [Classes 120(i) and 120 (iii)] In the production of slivers of improved uniformity, a formation of formations of fibrous material exhibiting a shortinterval irregularity which is of substantially uniform period has or have the irregularity evened out, without any action constantly controlled by weight or thickness measurement, by varying the draft upon the formation in a drafting operation periodically with the same period as the irregularity and/or by imposing a systematic phase displacement of the irregularities of separate formations in a doubling operation. The formation or formations may be produced, with the said uniform-period irregularity, as an initial step. As shown in Fig. 1, jute or other hard fibres are pieced out in handfuls into compartments 4 of an endless conveyer 3 which delivers them by gravity on to the feed apron 1 of a Goods machine or jute spreader 2 with a uniform overlap between successive handfuls. Two conveyers 3 may be arranged to deliver alternatively from either side of apron 1. The draft in machine 2 is varied with the same interval as the irregularities produced in the laying-on process, e.g., by varying the number or diameter of the pins in the gill bars, by varying the speed relation between the feeding and drafting elements of the machine, by means of an eccentric roller producing variation of pressure, or by varying the size of the gap left free for the material. As shown in Fig. 4, the teeth 13 of the sprocket roller 10 driving gill bars 9 of the slow chain of a jute spreader are of varying depth so that the resistance to the drawing-off of the fibres is automatically varied periodically. The rods 17 of the lantern rollers 16 co-operating with the fast chain of the spreader may carry sleeves 18<SP>1</SP>-18<SP>6</SP>, Fig. 6, to vary the draft at successive points in the sliver width to distribute the fibres evenly in the sliver length. To even out further the periodic irregularity of the slivers, several slivers such as 14<SP>1</SP>, 14<SP>2</SP>, Fig. 8, are doubled on leaving the machine, a phase displacement between the irregularities of the slivers being introduced by making the paths of the slivers to the doubling point differ by a length equal to the interval length of the irregularity divided by the number of slivers. Alternatively, the irregularity may be suitably marked at the end of each sliver to enable relative displacement to be effected when doubling on a subsequent machine. According to the first provisional Specification, the irregularity may be evened out during drafting by means of a series cf lantern rollers having eccentricallyarranged bars and disposed at such intervals that a series of light regions of the sliver are given an increased condensing action simultaneously.
