Abstract: 363,494. Feeding sheets. HESSER MASCHINENFABRIK AKT.-GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. Dec. 4, 1930, No. 36553. Convention date, Dec. 19, 1929. [Class 100 (i).] Pile supports.-A self-locking device, for adjusting the height of parts of sheetfeeding apparatus, comprises a plate p, as shown in the Figure, normally urged upwards by a weight m. The plate is prevented from rising by the action of a ball k or roller, caused by a spring n to exert a wedging action between the rod l supporting the plate and an oblique surface u. When, however, a sheet is to be fed from the top of the pile S by a stamp L, the stamp descends into contact with the top sheet. A tappet a<1> pushes a rod b down against the action of a spring b<11>, and the bottom of the rod, through a lever f and pushrod h, releases the ball k and allows the rod l and plate p to rise and carry the pile upwards against the stamp. Upon the stamp rising again; the ball is pushed into wedging position by the spring r and stops any further ascent. The device is applicable also to parts of packeting, wrapping, bag-making, and like machines.

Most of the subject matter of this Specification is disclosed in Specifications 1,221,221 and 1,221,222, but the present claims are concerned with means for supporting the implement on the ground and with the drive to the rake head(s). The implement of Specification 1,221,222 may also be modified as shown in the present Fig. 5 in that the implement is secured to the tractor by a single draw bar 64 pivoted by a forked end about a vertical pin 68 to a connector 65 which is pivoted about horizontal pins 66 to vertical plates on the main beam 1. A crank handle 67 on a screw-threaded spindle adjusts the draw bar vertically, and a pin-and-slot connection maintains the bar in a chosen angular setting about the pin 68. The implement of Specification 1,221,221 may be modified by the substitution of pivoted ground-engaging support shoes (or a single ground wheel) for the ground wheels of that Specification.
Patent GB-321097-A (GB)
Title: Improvements in hydro-turbine air pumps and controlling mechanism therefor
IPC: F04C19/00
Filed: 1928-12-14
Abstract: 321,097. Jennings, I. C. Dec. 14, 1928. Pumping machines and apparatus; starting, facilitating.-In a sewage system where ejection from a tank is obtained by air pressure, an air pump of the water ring type is employed, and priming water is introduced into the rotor chamber when the pump is started into operation, The pump 25 is shown in Fig. 8 and has an inlet 32 in connection with ports 34, 35, and an outlet 41 in conneotion with ports 38. The outlet 41 is connected by the pipe 26, Fig. 1 to the upper part of the tank 20; sewage enters by the pipe 21 and leaves by the pipe 22, valves 23, 24 being arranged in the pipes to prevent any reversal of the flow. The arrangements are such that when the float 27 is raised sufficiently by the sewage in the tank, it closes a switch to start the motor driving the air pump, and at the same time opens a valve to admit priming water to the pump. Air is pump into the tank 20 and the sewage is discharged through the pipe 22 until the float 27 drops to open the switch to stop the pump. The water in the pump then occupies only the bottom part of the pump casing as shown in Fig. 8. The receiver 20 is thus effectively vented by the clear path from pipe 41 through the pump and the inlet 32 to the atmosphere. The float 27 operates a pivoted arm 63 engaging a slide 64 between adjustable nuts on the rod 65. The depression of this road closes the switch 72 and raises the projection 80 on the arm 77, thereby allowing a spring to open the valve 51 for the priming water which is admitted by the pipe 50 to the upper part of the pump near an admission port 34. A spring 85 causes the switch to snap over from one position to the other. Specification 214,202 is referred to.

Title: Switch actuating mechanism
IPC: B60Q1/42
Filed: 1971-08-06
Abstract: 1389409 Mechanical switches LUCAS ELECTRICAL CO Ltd 1 June 1972 [6 Aug 1971] 37033/71 Heading H1N A switch actuating mechanism for a selfcancelling direction indicator switch comprises a pivoted lever biased to a central position by a spring 17 having arms 17a, 17b. If the lever is turned in one direction, say anticlockwise, spring arm 17a runs up ramp 24 on the body and over detent shoulder 24a, which holds the lever in position. Simultaneously sliding member 27 is allowed to slide down slot 26 under the influence of springs 28 towards steering column 34 and its striker 35. Rotation of column 34 anticlockwise moves striker 35 so that member 27 can move to the full extent of slot 26. If column 34 is then rotated clockwise to its initial central position, striker 35 rotates pivoted member 27 anticlockwise so that cam surface 29 on member 27 lifts spring arm 17a from detent 24a and the lever is returned to its central position by spring 17. Simultaneously member 27 is urged by portion 32, Fig. 3 (not shown) of the lever back up slot 26 clear of engagement by striker 35. Similarly if the lever is turned clockwise, spring arm 17b runs up ramp 25 and over detent 25a where it is held until cancelled by striker 35 rotating member 27 clockwise so that cam surface 30 on member 27 lifts spring arm 17b clear of detent 25a. Detent shoulders 24a; 25a are sloped so as to retain arms 17a, 17b but to cause the arms to ride up the shoulders if the lever is manually returned to a central position.

A sleeve 12 is rotatably mounted on the tube 6 and has a flanged aperture 13 which is connected to the coupling piece 15 and which can be made to overlap to a varying extent with an aperture 17 in the tube 6 in order to regulate the suction at the opening 18. A spring 30 urges the sleeve 12 towards a collar 27 the latter having a series of recesses 29 for co-operation with a lug 28 on the sleeve 12 which can thereby be located in various adjusted positions. A telescopically retractible and extensible branch piece 23 may be provided in the coupling piece 15, having a fume extraction orifice 26, and being of particular use in vertical welding. The end of the tube 6 may be flared as shown in Fig. 1 or provided with two relatively rotatable parts 20, 21 having angled ends, as shown in Fig. 2. The coupling piece 15 may serve as a handle for the torch. A shroud 22 may be provided on the torch to prevent disturbance of the flow of protective gas by the suction.

Abstract: 1,125,869. Wear compensating unit for joint assemblies. T. R. W. Inc. 11 Aug., 1967 [23 March, 1967], No. 37097/67. Heading E2F. A wear compensating unit for pivot joint assemblies comprises, in one embodiment (Figs. 1 and 3), a wedge unit 25 consisting of a bearing member 26 and a wedge member 27, the bearing member having a stop face 28 with a concave portion 29 for seating the end 20 of a stud 13. The wedge member has shoulder portions 37 and 38 out of which extends two integral flexible arms 39 and 40, the arm 39, in the unloaded state, terminating radially inward from the arm 40. During assembly of the pivot joint 10, the wedge unit is installed in the housing 11 in its compressed state and, as the use of the joint creates wear, the spring arms 39 and 40 force the wedge member away from the back wall 32 of the bearing member and increase the height of the unit, to take up any looseness caused by wear. In a further embodiment (Figs. 5, 6 and 7, not shown), a coil spring is placed within a bore, the spring bearing against the back of the wedge member to supply force to push the wedge member away from the back of ithe bearing member. In another embodiment (Fig. 9 and Figs. 8 and 10), the wedge member 65 is formed integrally with a bearing member (66) through a relatively narrow resilient strap 67 with its inclined face 68 on one side of the strap, while the bearing member is formed with its seating face 69 on the either side of the strap. The wear compensating wedge unit 64 is assembled by bending the strap into a U-shape position (Fig. 10, not shown). In yet a further embodiment (Figs. 11 and 12, not shown), the bearing member is integrally connected with the wedge member by two resilient side legs.

Abstract: Uranium bearing materials are treated with elementary chlorine in a liquid aqueous medium and the resulting solution is treated to precipitate an insoluble uranium compound.  The source material is preferably comminuted and leached with aqueous acidified hypochlorite solution, suitably bleaching powder and sulphuric acid.  The material before treatment with chlorine may be roasted in an oxidizing atmosphere with or without lime, or may be subjected to a chloridizing roast with a chloride such as common salt.
