Title: Improvements in or relating to ball bearings
Inventor: DOWNES DOUGLAS GEORGE
IPC: F16C33/66
Filed: 1952-06-19
Abstract: 719,829. Bearing cages. SPERRY GYROSCOPE CO., Ltd. April 24, 1953 [June 19, 1952], No. 15469/52. Class 12(1) In a ball or roller bearing, a cage 5 has an axially tapered outer surface 6 between which surface and the outer race 1 an annular gap is formed in which an oil ring 2 is established, thereby radially locating the cage 5. Oil flows along the outer surface of the cage due to centrifugal action. The outer race 1 may be chamfered to provide a sharp edge 4 at the gap or, alternatively, a groove may be formed in the outer race at that point. In a modification the cage is tapered axially in both directions, Fig. 4, whereby two such oil rings 2 are formed for locating the cage 5.

Title: Improvements in and relating to the liquid absorption of gases
Inventor: HELSBY FRANK WILLIAM
IPC: B01D53/18
Filed: 1953-06-05
Abstract: 744,785. Contacting gases with liquids. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 13, 1954 [June 5, 1953], No. 15519/53. Class 55 (2). In apparatus for contacting liquids with gases means are provided whereby the liquid is passed into a chamber to form initially a thin layer of liquid over a porous or foraminous support at the lower end of the chamber from a conduit or conduits leading directly onto the support and the gas is passed through the support into the liquid so as to foam the liquid into a space at least several times its original volume, the foam thus formed being allowed to overflow at the upper end of the chamber into a collector for used scrubbing liquid, the gases leaving by an outlet above the upper end of the chamber. Foaming agents are not added to the liquid unless the liquid in use does not of itself foam well. As shown in Fig. 1 a chamber 20 with a foraminous support 41 at its lower end is arranged in a vessel 26 such that an annular space is formed between chamber 20 and vessel 26. Below the support 41 there are provided chambers 47 and 35 to which gas and liquid are passed respectively by inlets 45 and 36. Liquid from chamber 35 is fed to the surface of the support 41 through a series of tubes 40 which extend through the gas chamber 35 and the foraminous support. Foam produced rises in the chamber 20 and falls into the annular space between chamber 20 and vessel 26, used liquid is withdrawn at 39 and the treated gas passes out through outlet 31. The foraminous, support may be made in metal or a plastic, or ceramic material and preferably comprises as shown in Fig. 4 an assembly of thin metal strips 50 laid side to side in square formation and bolted together between end-strips 54. The strips 50 are crimped, indented, or as shown chanelled on one side. In a modification shown in the drawing of the Provisional Specification the apparatus comprises two vertical chambers 1 and 2 with foraminous supports 3 and 4 respectively. The chambers are arranged in a vessel 6 so that an annular space is left between the chambers 1 and 2 and the vessel 6; the lower chamber 2 is also surrounded by an inner container 5 such that gas entering by an inlet 10 passes in series through the two chambers. Liquid is supplied to the upper chamber through an inlet 7 passing onto the support 3 through peripheral openings. Foam produced passes into the space between the chamber 1 and vessel 6 and the liquid separating from the foam falls to the base of the vessel and passes onto the support 4 of chamber 2. Foam produced in chamber 2 passes into the space between chamber 2 and inner container 5, used liquid is withdrawn at 11 and the treated gas leaves at 13.

Title: Telecommunications systems

Filed: 1971-05-19
Abstract: 1327668 Automatic exchange systems SIEMENS AG 19 May 1971 [20 May 1970] 15730/71 Heading H4K A pair of signal generating devices are connected alternately to a signal-wire multiple so as to transmit control signals over one or more of the wires of the multiple, the devices being decoupled from each other by means of rectifiers, the elementary signal producers within each generator being decoupled from each other by means for example of relay change-over contacts and a fault detecting arrangement being provided for disconnecting one of the generators in the event of a defective rectifier. The devices may be markers for a relay switching network so that as shown the wires t of multiple T extend to e.g. the column control wires, of a relay matrix. In the rest condition, the elementary signal producers viz. change-over contacts ls1 to ns1 and 1s2 to ns2 in the two markers S1, S2 have their break contacts connected via a respective decoupling rectifier to respective wires of the multiple. In operation, a wire t1 say, is marked with positive potential from S1 say, by closing contacts ls1 and 2a1. Simultaneously rectifiers 2G1 to nG2 are reverse biased by the application of earth potential via contact la1. Test circuit K1 determines that only one wire is marked by measuring the current flow therethrough. Excess current would occur if more than one contact s1 is operated or, more importantly, if one of the rectifiers 1G2 ... nG2 in the other marker S2 had broken-down in the reverse direction so causing marking potential to be applied to all the wires T e.g. in a path 1s1, 1G1, 1G2 say, 1s2 and thence all of 2s2 ... ns2, 2G2 ... nG2, t2 ... tn. In this circumstance K1 brings up relay B2 which effectively locks out all  markers other than the faulty one S2 and generates an alarm signal. S2 then handles all the marking until the fault therein is rectified when normal alternate use is resumed. If a rectifier goes open circuit, again say 1G2, no current will be detected by K2 during a normal marking operation of t1 by S2 so that this time relay B1 in the non faulty marker is brought up and this marker takes-over all the marking functions. In an alternative arrangement (Fig. 2, not shown) high resistance earth is permanently connected to each multiple wire and the detectors K1, K2 are connected to the common wire on the make side of contacts 1a2, 1a1 in the other marker whereby false potentials due to defective rectifiers are immediately detected and appropriate remedial action instituted.
