Title: Coupling device
IPC: F16D1/116
Filed: 1976-08-23
Abstract: 1536898 Shaft couplings JEAN WATERSCHEID GmbH 23 Aug 1976 [23 Aug 1975] 35020/76 Heading F2U A device for coupling the P.T.O. shaft 27 of a tractor to a universal shaft 10, 40 of an agricultural machine comprises inner and outer torque transmitting coupling members 24, 10 held together by releasable fastening means 21, and a drum member 17 associated with one of the coupling members (24) and provided with a bearing 4 which acts as a fulcrum for a bearing member 8 associated with the other coupling member (10) when a lever 7 connected to the bearing member is moved to effect relative movement and coupling of the coupling members. The inner coupling member 24 complete with drum member 17 and bearing 4 is mounted on the splines of the P.T.O. shaft 27 after a locking ring 35 has been displaced against the action of a spring 25 by means of tools (e.g. screwdrivers) inserted through bores 50 in the drum member to permit balls 30 to move into their bores when engaged by the chamfered end of the shaft. The balls 30 spring into locking engagement with a groove 32 in the shaft by the spring return of the locking ring 35. The drum member 17 is mounted on the inner coupling 24 by ball bearings 23 and held against rotation by tractor member 49. The agricultural machine is provided with a coupling member 10 connected to one yoke of a universal joint 1, the guard 36 surrounding the joint being mounted on ball bearings 41 and provided with a pair of diametrically opposed swivel pins for carrying a bifurcated bracket to which the bearing member 8 and lever 7 are attached. The tractor is reversed towards the machine and the bearing member 8 hooked into the bearing 4. The lever 7 is then pivoted to swing the outer coupling 10 into engagement via the guard 36 and bearing 41. A splined connection is made between the inner and outer coupling members 24, 10. Balls 21 are first depressed by the chamfered end 19 to displace a ring 20 against the action of a spring 26 and then spring outwardly into a groove 18 in the outer coupling member 10 to position it axially. To release the coupling members the balls 21 are moved axially and into the cavity 29 by means of a control ring 16, 38 which is shifted axially by means of a lever 11 attached to one of the bolts 14 operable in oblique slots 31. The outer coupling member can then be uncoupled by pivoting the lever 7 and then unhooking it from the bearing 4. In a modification, Fig. 4 (not shown) the drum member (17) is mounted for limited angular movement in brackets (61) on the tractor and is provided with oblique slots which cause angular movement of the drum member and consequential axial movement of the control ring when the lever (7) is moved laterally.

Abstract: 1,210,457. Digital data storage. SIEMENS A.G. 25 July, 1968 [26 July, 1967], No. 35514/68. Heading G4C. [Also in Division H4] In an exchange including a store KS in which cells Sz, each allotted to a respective input channel Z, store details of the relationships between input and output channels Z, A, and details of the last change in bit-state of data received over each channel, when a new change occurs details of the change are passed to a word register WR from which they are written in the appropriate cell Sz to update it during the readout phase of that cell, initiated when the change occurs. Dialling information from a channel Z is passed over multiple line ECV, in which each pulse marks a fixed combination of the lines, to cause the address of the called subscriber to be stored in a cell Sz allotted to Z. When a change in bit-state occurs on a channel Z address register AR accesses the relevant cell Sz and initiates a read-out phase in which information from the cell is read to a word register WR, the change in bit-state up-dated, and the information read out is re-written in the cell. Via multiple line ACV and unit ACW the called subscriber is obtained and informed of the bit-state change. If required information in word register WR is processed prior to being rewritten in the cell.

Title: Improvements in or relating to the preparation of lead-sulphate products, particularly adapted for use as pigments
IPC: C09C1/14
Filed: 1938-12-06
Abstract: 522,362. Lead sulphate. NATIONAL LEAD CO. Dec. 6, 1938, No. 35535. Convention date, Dec. 6, 1937. [Class 1 (iii)] A lead sulphate-containing pigment is made by reacting a lead oxide slurry containing a sulphation promoting catalyst with sulphuric acid until all the lead is converted into hydrated tribasic lead sulphate and then reacting on the tribasic sulphate with further sulphuric acid until it is substantially converted to a thickened mass of acicular crystals of the monobasic lead sulphate. Further sulphuric acid may be added to convert between 20 and 60 per cent., preferably 37 per cent., of the mass to normal sulphate. The crystals retain their acicular form. A slurry consisting of acetic acid, lead oxide and water in the proportions, for example, of 1:60:520 is placed in a container. Air is blown through to oxidize any metallic lead and to agitate the mixture, agitation being assisted by a mechanical mixer. The reaction is carried out at from 60-95‹C. preferably at about 80‹C. The sulphuric acid of the second and third stages is added slowly and uniformly, the time for these two stages being 3¢-4¢ hours, the whole process taking 5-6 hours. The end point of stages 1 and 2 is marked by a sudden increase in electrical resistance of the slurry. The final product is suitable as a pigment without further treatment.

[Class 110 (iii)] [See also Group XXXI] In combustion power plant for driving vehicles, such as rail cars, comprising elongated constant volume explosion chambers, these chambers, together with other elongated parts of the plant, are arranged in an upright position, and as symmetrically as possible in order to economize space. A gas turbine plant, with electric transmission to the driving wheels is described. It comprises two vertical explosion chambers 13 having air valves 17 and fuel valves 18 situated at the top and discharge valves 19 at the bottom. The oil distributer 20 controlling the valves, the electric motor 22 driving the fuel pumps 25, and the ignition mechanism 27 are mounted on a cross-beam 24 joining the explosion chambers. The explosion products are supplied to two separate gas turbines 14 which drive compressors 35b. These compress the intake air in series, an interstage cooler 36 being arranged between them. Both turbines exhaust into a pressureequalizing chamber 41 which acts as a steam boiler. The gases then pass to a power turbine 15, Fig. 3, where they are used mixed with exhaust steam from a power turbine 16 on the same shaft. Steam for the turbine 16 is generated from the waste heat of the plant. Water from the cooling jackets is directed tangentially into a vaporizer 49 situated above and about the gas products chamber 41, and the steam produced is led through a heat exchanger 45 in the path of the final flue gases to a superheater 56, and thence to the turbine 16. The power turbines 15, 16, drive, through gearing 58 and flexible couplings 12, an electric generator 8 which is mounted on an auxiliary frame, and supplies current to motors on the bogie wheels and for other purposes. The engine parts are mounted on a frame 59 which can be lifted out of the vehicle.. The arrangement of the sub-frame may be modified. An arrangement is described in which the explosion products generate steam before being used in the turbines driving the compressors.
