Patent GB-388239-A (GB)
Abstract: 388,239. Coin-sorting apparatus. SMITT, H. M., 5, Middellaan, Bilthoven, Utrecht, Holland. April 8, 1932, No. 10104. - Convention date, April 9, 1931. [Class 116.] An apparatus for sorting coins and like articles comprises a path or track for the coins or the like consisting of an inclined trough having a transversely inclined or roof-shaped bottom, calibrated sorting slots formed in said bottom and means for causing the track to vibrate longitudinally. The trough may be preceded by a supply track, means being provided for causing the tracks to vibrate longitudinally as a whole or individually. The supply track is preferably oppositely inclined to the sorting trough in order to limit the longitudinal dimension of the apparatus. The vibration of the trough or troughs may be obtained either mechanically or by electrical means, and is advantageously effected by causing the track to be acted upon longitudinally by a spring or springs, and mounting an electromagnet, supplied with alternating or interrupted direct current, opposite one end face of the track which, if necessary, is provided with a paramagnetic element. In the embodiment shown in sectional elevation in the Figure, the upper trough 2, of semicircular cross section and closed at both ends, is provided near its lower end with an orifice 3 and is suspended by arcuate blade springs 4, 5 from the sides of the casing. Above this trough is a semicircular or funnel-shaped cup 6 having an extension opening into the trough. Opposite one end of the trough, which contains a paramagnetic element, is mounted an electromagnet 9 for causing the trough to vibrate longitudinally. The lower oppositely inclined track, which is similarly mounted and vibrated, consists of a trough 11 having a roof-shaped bottom 12, provided, adjacent to the vertical sides of the trough, with relatively long calibrated slots 15 .. 18 corresponding in width to the successive diameters of the coins to be sorted. The slots are not continued up to the wall of the trough but a narrow strip is left on which one edge of the advancing coins, which on account of the inclination of the bottom will always abut on the wall, is supported. Below the slots are funnels communicating with collecting receptacles. A counting device may, if desired, be connected by means of a tube to the funnels to replace the collecting receptacles. In order to sort coins of the same diameter but of different weights, a flap is provided acted upon by a spring so adjusted that the heaviest coins will depress the flap while the lighter ones slide over it. In a modification, the sorting trough may have a transversely inclined bottom presenting one series of slots only. In another modification, the vibration of the troughs may be obtained mechanically by means of a small motor. In a further modification the two troughs may be arranged in alignment, constituting an integral unit adapted to vibrate 'longitudinally.

Title: Improvements in or relating to the Over-End Winding of Yarn
Inventor: BISSET DOUGLAS CHISHOLM
IPC: D01H1/30
Filed: 1966-09-01
Abstract: 1,198,058. Spindle drive. IMPERIAL CHEMICAL INDUSTRIES Ltd. '14 Aug., 1967 [1 Sept., 1966], No 39115/66. Heading D1D. In over-end winding of yarn using a rotating spindle and traverse, the speed of rotation of the spindle is varied cyclically about selected values thereof during the winding, or about a mean value maintained constant throughout winding, and the frequency of the cyclical variation changed between at least two values during winding according to a programme calculated to avoid any value of the ratio cylic variation frequency: traversing frequency over being one consisting of whole numbers, i.e. less than 5 such as would itself lead to patterning occurring. The cyclical frequency can be varied between three values. The amplitude of the cyclical variation can be 3-15% of the constant mean spindle speed and it can be varied according to a programme, e.g. using a computer. The mean spindle speed can be gradually reduced during the whole of the winding period. The method of the invention may be combined with more radical programming of spindle speed and controlled or random variations in ring speed and yarn delivery speed. In a first example the spindle speed was reduced from 9,750 r.p.m. to 7,350 r.p.m. during winding and in addition the cyclical variation frequency was shifted three times, the cyclical frequency amplitude being 10% of the instant spindle speed. In a second example mean spindle speed was maintained constant at 6,850 r.p.m. and the speed was varied by 10% about the two mean descrete frequencies 0.0384 cps and 0.048 ops. Specifications 1,198,056 and 1,198,057 are referred to.

Abstract: 974,944. Treating charge and ventilating crankcases. S. SMITH & SONS (ENGLAND) Ltd. Oct. 8, 1963 [Oct. 16, 1962], No. 39216/62. Heading FIB. Crankcase gases are returned to the induction pipe through a valve mechanism comprising a first valve 18, Fig. 1, which is closed when the engine is stationary but opens when the engine is running and a second valve 28 which is normally open but tends to close as the crankcase pressure falls. The outlet 15, Fig. 1, is connected by pipe 16, Fig. 3, to the induction pipe 17, and outlet 30 by pipe 30a to the crankcase 31, the air inlet of which, through the valve cover 33, is restricted by a filter 35. Valve 18 remains closed during starting of the engine to avoid diluting the fuel-air mixture but is opened by suction immediately the engine starts. Valve 28 is controlled by a diaphragm 26 subject to the pressure in the crankcase; as the crankcase pressure decreases, the valve 28 is moved towards orifice 14 to throttle the flow of crankcase vapours and maintain an approximately constant suction in the crankcase, e.g. within the range of 1 to 5 inches of water. In Fig. 4, the valve cover inlet 36 is sealed and the valve cover connected through a flame trap and restricting device 43, 44, to the carburetter filter 40 to which the atmospheric side of the valve controlling diaphragm is connected by pipe 53. The flame trap 43, 44, contains wire gauze 48 and a rubber disc 49 which normally seats on a plate 45 so that the air flow into the crankcase is restricted by orifices 51. If a blow back past the pistons raises the crankcase pressure, the plate 45 lifts to allow pressure release through large orifices 52. In Fig. 7, the valve mechanism 10 is mounted on the oil filter opening of the valve gear cover 33, a passage 61 opening into the valve cover and an outlet 10 being connected to the induction pipe 17.
