Title: Improvements relating to loom lays
IPC: D03D49/60
Filed: 1934-08-28
Abstract: 427,524. Looms. BIRD, W. F., West Rolling Road, Springfield, and HEWTON, W. R., 1433, North 62nd Street, Philadelphia, both in Pennsylvania, U.S.A. Aug. 28, 1934, No. 24807. [Classes 142 (i) and 142 (iii)] Lays; beat-up motions; stop-motions ; shuttles.-Looms, particularly for weaving double pile fabrics, are provided with means for disconnecting the lay from its driving means in the event of a shuttle not being properly boxed, and for subsequently stopping the loom. The lay moves in a straight line inclined to the horizontal and is driven by pairs of cams 26, Fig. IV, having concentric and eccentric parts 30, 31 as described in Specification 425,091. Each follower pin 32 is carried by a slide 17 movable in a slot in the lay and has a slot 18 for sliding engagement with a bush 19 loose on the driving shaft 20. During normal operation, the slide is locked in the position shown by a spring-pressed arm 33 on the slide having a projection 35 in engagement with an abutment 36 on the lay. When a shuttle is boxed properly, the swell lever moves a guided rod 96<a> or 96b to turn a spring- controlled lever 94 or a similar lever 93 at the other side of the loom. A dagger 107 is thereby moved below the path of a bunter 111 on the lay. When a shuttle is not boxed properly, the dagger 107 remains in the position shown, and when the lay begins to beat-up, engages and turns the bunter 111 whereby a stop 86 is moved into the path of a fixed stop 87, and the arm 33 on the slide 17 is lowered to disengage it from the lay. The lay is thus disconnected from its drive while the slide 17 continues to move till the free end of the arm 33 engages an arm on a bell-.crank lever 122<a>, the other arm of which disengages the starting handle from its slot. Driving and stopping arrangements.-The loom is driven through a clutch under the control of a spring-retracted rod connected to a bell-crank lever bearing on the starting handle. When the handle is pushed into the " off " position, it allows the bell-crank lever to turn and release the clutch. Shuttle-boxes ; picking-motions.-The shuttleboxes, 50, 51, Fig. III, are stationary, and are provided in their backs with slots for the pickers which are guided on spindles to the rear of the boxes. The picking-sticks 54, 55 pass through slots in the pickers and move inwardly to pick a shuttle from each shuttle-box simultaneously. The picking-sticks are operated each by a pair of " picker balls " 64, 65 arranged symmetrically on a shaft 42 and adapted to engage bat wing cams 66 on levers 72 connected by straps 74 to the picking-sticks.

Patent GB-762102-A (GB)
Title: Preparation of red oxide of iron
Inventor: BENNETCH LEONARD M
IPC: C09C1/24
Filed: 1953-09-11
Abstract: Red ferric oxide is prepared by oxidizing a mixture of nearly equivalent quantities of ferrous salt and alkali to form colloidal seed particles, and effecting the growth of ferric oxide thereon until the particles reach the desired colour.  The proportion of alkali should be 0.9 to 1.1 times the equivalent of the iron salt. The precipitated slurry is continuously oxidized by blowing air through it, the slurry is heated to 50 DEG  to 100 DEG C. and ferric oxide is precipated on the seed particles either by further additions of alkali and iron salt or by adding metallic iron in the presence of a small amount of iron salt as catalyst. The product progressively darkens and the oxidation process is continued, e.g. from 1 to 7 days until the desired shade is obtained.  The precipitate is filtered, washed, dried and disintegrated and may be further darkened by heating at about 1150 DEG F.  The alkali is preferably added to the iron salt as it yields a slurry of lower viscosity.  U.S.A. Specification 2,574,459 is referred to.

Abstract: 785,807. Magnetic recording and reproducing. ESSO RESEARCH & ENGINEERING CO. Sept. 2, 1955 [Sept. 28, 1954], No. 25259/55. Class 40 (2). [Also in Group XXXIX] Noise, due e.g. to record speed variations, is substantially eliminated in a frequency-modulated magnetic recording and reproducing system by separately magnetically recording in a recorder 4 not only the input signal which modulates the carrier frequency of an oscillator 2 but also an auxiliary signal of frequency the same as the said carrier frequency, separately reproducing and then demodulating the two signals in reproducer 5 and discriminators 6, 7, and feeding into a difference amplifier 8 the two demodulated outputs in opposite phase to each other. By this system any noise developed during recording and playback by record speed changes is present in both signals and constitutes the only output from discriminator 7, and by subtraction of such noise by amplifier 8 from that in the output of discriminator 6 there is produced a noise-free signal output which corresponds to the input signal. The auxiliary signal is produced by either the input signal oscillator 2 or an oscillator 3 and there may be a number of input signals each fed through a respective channel similar to that described above. The system is applicable to seismic prospecting, and frequency valves are given in the Specification.
