Title: Chain guiding and gripping devices
IPC: B66C1/12
Filed: 1960-10-11
Abstract: 955,824. Fairleads; chain stops. HARLEY PATENTS (INTERNATIONAL) Ltd., and F. B. HARLEY. Oct. 11, 1960 [Oct. 12, 1959], No. 34577/69. Heading B8B. A fairlead device for a link loop chain 10-13 (Fig. 4), comprises a plate 14 having in it a cross-shaped aperture having four arms 22, 23, 24, 25, formed by two intersecting slots. As shown in Figs. 3 and 4, the aperture is formed in two plates 14, 15, between which a latch 31 is slidable from a position (Fig. 3) in which both slots are unobstructed, to a position in which the slot-arms 24, 25 are obstructed, thus locking the chain against movement. The latch is formed with guide slots 33 which have turned-in ends 34 which co-operate with guide pins 35 to lock the latch in each of its operative positions. In a modification (Fig. 5), the plates 14, 15 are replaced by a single plate 50 and one of the slot-arms (53) of the cross-shaped aperture is open-ended so that the chain can be slid laterally into the device. The chain is locked in the device by allowing a vertically disposed link to drop into an elongated slotarm 56 of the cross-shaped aperture. The chain is retained in this slot-arm 56 by means of a latch 59 which is moved from the position in full lines to the position in dot-dash lines. A pin 67 on the latch 59 engages a recess 68 on the plate 50 so as to prevent the arm 53 of the aperture opening when the chain is under load. Recesses 64, 64, on each side of the plate 50 serve to provide a bearing for the chain links adjacent to the link locked in the slot-arm 56. In a modification of this construction (Fig. 9, not shown), the latch 59 is dispensed with and the size of the plate 50 is enlarged so as to include two further cross-shaped apertures, each of which has an elongated locking slotarm 56 but has no open-ended slot-arm 53. In a further modification (Figs. 11 and 12, not shown), the chain is prevented from escaping from its slot-arm 56 by means of a latch which is pivotally mounted on the plate 50 by means of a rubber bush-type connection. The resilience of the rubber bush keeps the latch in engagement with the vertically disposed chain link in the arm 56 but the latch can be turned and lifted against this resilience to release the chain. In the construction shown in Fig. 15 a cross-shaped aperture 75 is formed in two spaced plates 155 between which is disposed a locking latch 154 pivotally mounted at 151 and urged into chain-locking position by a spring 156.

Title: Improvements in apparatus for the determination of deleterious vapours in gas or air
IPC: G01N1/00
Filed: 1947-12-31
Abstract: <PICT:0647921/III/1> In apparatus for detecting acid - forming substances such as halogens or substituents thereof in gas or air of the type in which the gas under pressure is passed through a combustion or catalyzer tube to form the acid substances which are then detected on a colourimetric test paper, the gas is first passed through an auxiliary chamber connected with the tube inlet and having a greater passage area for the gas stream than that of the tube, the auxiliary chamber also being provided with a single main opening for the inlet of gas and discharge of excess gas.  The gas is forced through the chamber by means of a fan or of a relative movement between the apparatus and the gas such that the pressure in the chamber is above atmospheric and a greater quantity of gas passes through the chamber than through the tube.  As shown, gas is drawn into auxiliary chamber 11 by fan 12, some of the gas then passing through the tube 13 containing an electrically-heated platinum-wire catalyst and the remainder being discharged through the clearance between the fan impellor and the fan housing.  The test-paper, e.g. a dimethylaminoazobenzene - impregnated paper, is clamped in a two-part apertured holder 14 and held against the tube outlet by spring 18. Gas escapes from tube 13 through transverse grooves 26.  Tube 13 is removably insertable in an aperture in the auxiliary chamber and is held in position by a spring 27 which also serves as a current conductor to the platinum wire.  To prevent deleterious vapours from being absorbed in the lubricant around the fanshaft, a minor stream of gas is bled off from chamber 11 through the annular gap 38, chamber 36 and apertures 37 to the atmosphere.

Filed: 1920-12-16
Abstract: 176,897. Medway, E. M., and Smith, E. C. Dec. 16, 1920. Mechanically tripped and released switches. -In electrically-actuated lifts in which current is cut off automatically when the gate is opened and vice versa, on closing the gate one part of a catch causes a conducting member to move towards a second conducting member which latter is caused by another part of the catch to move towards and make contact with the first - mentioned conducting member. When the catch 2, Fig. 1, enters the latch 3 the bolt 5 is raised and the consequent movement of the rocking lever 8 causes the pivoted arm 11 carrying contacts 13 to move downwards. When the beak 4 drops over the latch 3, the bent end of the rocking lever 16 is depressed and the other end supporting the contact bridge piece 18 is raised into engagement with the contacts 13. The movement of the lever 16 is limited by stops 19, 20 which are so disposed that contact cannot be made between the two conducting members if only one of the members is moved. A projecting lug 21 prevents tampering with the switch. In a modification, the conducting members are mounted on vertically movable rods which are actuated through rocking levers by a pair of vertically movable bolts. In a further modification a roller 40, Fig. 3, on the belt 5 bears against a cam surface 43 on a pivoted arm 41. A bellcrank lever 45 pivoted in the arm 41 and normally maintained in the same position relatively to it by a spring 47 is connected by a cable 48 to a terminal 49. The beak of the catch rocks a three-armed lever 16 supporting a block of conducting material 51 connected by a cable 52 to a terminal 53. In each construction upward movement of the bolt 5 is prevented by a cam 37 except when the lift is at a landing. A ramp fixed to the lift well at each stopping place turns the shaft 38 carrying the cam 37 so as to free the bolt.

Title: Improvements relating to the recovery of uranium from solutions
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: C22B60/02
Filed: 1954-12-08
Abstract: Solutions containing uranyl ions and other uni- or bi-valent ions are caused to flow in contact with a cation-exchange material containing carboxyl groups until the proportion of uranyl to other exchangeable cations in said material is substantially greater than in the solution, and preferably substantially all the exchangeable cations are uranyl ions.  The uranyl ions are then recovered from the exchange material, e.g. by treating with 10 per cent hydrochloric acid.  Provided the solution still contains the uranyl cation, the pH may be above or below 7.  The cation exchange material may be in the hydrogen or salt form, preferably the former when used in acid solution.  Examples are given of the separation of uranyl ions from copper or cobalt ions in dilute solutions using as exchange materials a methacrylic acid/divinyl benzene copolymer, a condensation product of phenol and formaldehyde reacted with quebracho tannin and chloracetic acid and a hydrolysed ethyl acrylate/divinyl benzene copolymer.
