Patent GB-117673-A (GB)
Title: Improvements relating to Clutches.
Inventor: COCK CHRISTER
IPC: F16D13/40
Filed: 1917-07-25
Abstract: 117,673. Ter Cock, C. July 25, 1917. Clutches, friction.-In friction clutches of the kind in which main clutch springs act during part of the period of engagement and disengagement through weaker auxiliary springs, the main springs are tension springs, while the auxiliary springs may act either in tension or compression. Fig. 1 shows the use of auxiliary compression springs. The main tension springs M are secured to the operating-collar E and to a disk E<1> loose on the driving-shaft 2. The auxiliary springs C connect the collar E and the driven clutch-part R. During disengagement, the collar E removes pressure from surfaces X on lugs secured to the part R, and subsequently relaxes the tension on the springs C until the collar engages a surface Y on the port R and positively disengages the clutch. During engagement. the full pressure is not applied to the clutch until the collar E engages the surfaces X. The free movement of the collar E may be provided for by the use of pins and slots. When auxiliary compression springs are used, the two sets of springs may be arranged alternately around the circumference of a circle.

Title: The prevention of corrosion of wet metal articles
Inventor: ZIMMERMANN MAX
IPC: C23F11/08
Filed: 1965-03-16
Abstract: In a method for the wet preservation and corrosion protection of a metal article (e.g. of ferrous or cuprous metal) in contact with an aqueous phase, the aqueous phase contains 0.1 to 3000 mg. NH2NH2 per litre of water and 0.1 to 50 mg. methylene blue per litre of water. It may also contain 0.01 to 10 mg. of a complex heavy metal cyanide (calculated as the heavy metal) per litre of water, e.g. an ammonium or alkali metal complex heavy metal cyanide.  By heavy metal is meant Cu, Co, Ni, Ag and Fe. The method can be used for preserving steam producing plants, hot water plants, circulating coolers and heat exchangers from water containing oxygen and/or inorganic salts such as the chlorides, sulphates and/or nitrates of the alkali metals and alkaline earth metals.  In use, the colour of the solution serves to indicate whether or not excess NH2NH2 is present.  The activating effect of methylene blue on the reaction between NH2NH2 and O2 is enhanced by light energy, heating and the catalytic effect of metal surfaces.

Title: Improvements in stop mechanisms for drawing frames and similar textile machines
Inventor: MACKIE JOHN PRINGLE
IPC: D03D51/00
Filed: 1952-05-02
Abstract: 732,549. Stop mechanism for drawing head. MACKIE & SONS, Ltd., J. April 21, 1953 [May 2,1952], No. 11193/52. Class 120(2). In a stop mechanism for a drawing head of a textile machine repeated engagement is brought about between a pivoted detector and the sliver passing through the machine, the relative motion causing this engagement having a component transverse to the general direction of travel of the sliver, so that provided the sliver is moving at a speed greater than a critical value in relation to the transverse component of the relative motion, the detector is rocked about its pivot so as to prevent either the detector or a part acting with it from coming into either direct or indirect contact with an abutment, while under other conditions, the detector or the part acting with it engages the abutment either directly or indirectly and so causes the operation of a device for stopping the machine. As shown sliver 1 in its passage from drawing rollers 3, 4 to delivery rollers 5, 6 passes over a sliver plate 7 where it is engaged repeatedly by a detector member 8 pivoted at 10 to an arm 11 fixed to a rocker shaft 12 which is rocked by means of an eccentric 15 driven by gear 16 on the shaft of delivery roller 5. The eccentric is connected with the shaft 12 by a rod 22 passing through a bush 23 rockable on a link 24 secured to the shaft 12. A compression spring 26 is located between one side of bush 23 and an enlarged collar 27 on the end of rod 22 and is of such strength that under normal operational conditions the force in the rod 22 is insufficient to compress it. During normal operation as soon as the tip of the detector 8 engages the sliver it is carried forwardly with it about the pivot 10 as shown in Fig. 3. When the sliver is missing or is stationary or moving at a greatly reduced speed, however, the detector is not rocked about its pivot when it engages the sliver, or, if the sliver is missing, the plate 7, and the motion of the detector is thus positively stopped and as a consequence the motion of the shaft 12 is correspondingly stopped. The rod 22 continues to move to the right, however, and in doing so compresses the spring 26 and also causes an arm 31 by engagement of the collar 27 with it, to be rocked about its pivot 32 such that its opposite end 33 operates a micro-switch 34, as shown in Fig. 4, to stop the machine. In a second embodiment the sliver plate is made to oscillate instead of the detector to bring about the repeated engagement of the sliver with the detector. Means are also described whereby the mechanism can also be caused to operate when choking of the sliver occurs. Specification 706,192 is referred to.

Abstract: 560,867. Potato harvesters. JOHNSON, T. S., and JOHNSON (ENGINEERING), Ltd. Dec. 21, 1942; No. 11232. [Class 6 (iii)] [Also in Group XXX] In a potato harvester in which potatoes are lifted by a share 20 on to an inclined conveyer a which delivers them on to horizontal conveyer c through which they pass to a transverse elevating conveyer d, soil passing through the conveyers a, d and the tops and large lumps of earth being discharged by the conveyer c at the back of the machine, the return run of the conveyer d passes beneath the return run of the conveyer c. The conveyer a is connected by rods 13 to cranks 14 on a cross-shaft 15 operable through a crank 16 and a connecting rod 17 for pivoting about the driving shaft 11 to adjust the depth of cut of the share 20. The'shaft 11 is driven by a chain 12 from a shaft 4 connected by a chain drive with the axle 8 or through gearing in a box 5 and an inclined shaft 6 with a power unit on a towing tractor. A rotary agitator having a cylindrical surface formed by spaced bars or slats may be arranged between the conveyers a, c and driven through gearing from the shaft 11. Guide plates 25a are disposed above the conveyer c, which is also driven through gearing from the shaft 11 and may be jogged as-by means of an eccentric mechanism. The conveyer d is driven through a chain 31 and bevel gearing from the shaft 11 and its upper end may be raised or lowered by connecting the stay rods 27 to crank arms on a shaft connected through toothed or worm gearing with an operating handle. The conveyer d may be provided with a hopper 34 or shoot discharging into a cart driven by the side of, or attached to, the machine or the shoot may discharge into a trailer. The hopper 34 has a pivoted part 35 controlled by springs 37 for discharging the potatoes in bulk. The bars 22, 28 of the conveyers c, d may be covered with rubber &c., the bars at intervals being raised above the level of the other bars. A seat 44 is provided adjacent the conveyer d. The wheels 2 may be adjustable to vary the width of the track.
