Abstract: 693,176. Lubricating. WAKEFIELD & CO., Ltd., C. C. July 19, 1951 [July 20, 1950], No. 18191/50. Class 12 (iii). A distributer for lubricant comprises a pair of closed ended cylinders 14, 15, having reciprocating plungers 10, 11 therein, the plungers operating barrel valves 24, 25 by means of pins 12, 13 engaging slots in discs 18 and 19, the valves controlling passages leading to opposite ends of the cylinders so as to place the passages alternately into communication with a source of liquid under pressure and with delivery conduits. The discs 18, 19 are cut away at 20, 21, 22, 23, respectively so that a disc can only be rotated when a cut-away portion on the other disc permits. Barrels 24, 25 positioned in the casing 26 transversely to the cylinders 14, 15, are provided with circumferential and axial grooves 27-32, the casing 26 being provided with a single oil inlet 33 which communicates with the valve bores through oppositly directeed ports 34, 35 between the bores. The bore for the valve barrel 24 is provided with diametrically arranged delivery passages 36, 37 and with two similarly positioned ports and passages 40, 41 leading to the ends of cylinder 15. Similarly the bore for the barrel 25 is provided with inlet ports and passages 42, 43, connected to the ends of cylinder 14, and delivery passages 38, 39. In operation, Fig. 5, oil is admitted via the inlet 33, port 34, groove 30 and port 43 to the left hand of cylinder 14, and through groove 27 and port 40 to the left hand of cylinder 15, the plunger 11 remaining stationary whilst the plunger 10 moves to the right to force oil through the passage 45, port 42 and groove 32 to the outlet 38. When the plunger 10 moves it engages and rotates the barrel 24 into the Fig. 6 position so that oil then passes around the groove 27, out through the passage 41 to move the plunger 11 to the left, which movement forces oil out through the delivery passage 36. The plunger 11 in moving rotates the barrel 25 into the Fig. 7 position so that oil is then forced out through the port 39, the plunger 10 then moving again and operating the valve 24 to the Fig. 8 position for oil delivery through outlet 37, thus completing a distributing cycle.

Abstract: 1359142 Central heating systems BRITISH GAS CORP 15 July 1971 [16 April 1970] 18321/70 Heading F4U [Also in Division F2] A radiator valve, which is designed to be incorporated in both the supply and the return lines of a radiator and which permits removal of the radiation without prior draining of the latter, comprises first and second housing parts 18 and 25 which are releasably securable together by a nut 24 and which contain, respectively, first and second valve members 22 and 30. The first housing part 18 is anchored to a face-plate 11 behind which there is disposed the supply or return pipe 19, the valve member 22 contained in this housing part being biased on to a seat 23 formed on the housing part to close off the supply or return flow. The second housing part 25 includes a supply or return connection 26 leading to the radiator, the valve member 30 contained in this part being coupled to an externally accessible operating shaft 37 and being movable by such shaft relative to a valve seat 31. With the housing parts coupled, operation of shaft 37, as by a handle 38, unseats valve member 30 which in turn unseats valve member 22, engagement of the two valve members being by way of projection 32 carried by valve member 30. On closing the flow path, i.e. by manually seating valve member 30 and so allowing valve member 22 to be seated by the action of its spring; the housing parts may be separated without the passage of liquid past either of seats 23 or 31. The supply and return valves are preferably located proximate the centre of the radiator (Figs. 1 and 2, not shown). The coupling nut 24 may instead secure a coverplate (Fig. 4, not shown), or a draining connector (Fig. 5, not shown) which includes a central spigot (42) for unseating valve member 22.

Title: A frequency control system for a motor-alternator
Inventor: WRATHALL ROBERT WILLIAM
IPC: H02P9/42
Filed: 1949-07-11
Abstract: 687,411. Automatic frequency control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 10, 1950 [July 11, 1949], No. 18323/49. Class 38 (iv). In a frequency control system for a motoralternator the motor field is controlled by a resistance which is adjusted automatically in accordance with alternator frequency and motor field current. As shown, to maintain constant the frequency of an alternator 2 driven by a D.C. motor 1, the voltage across a condenser 4 connected in series with a resistance 3 across the alternator terminals is rectified and energizes a winding W<SP>1</SP> relieving spring pressure on a carbon pile 6 in series with motor field 1a. To overcome inertia a further winding W2 of the carbon pile regulator, acting in opposition to winding W1, is connected in parallel with the motor field to amplify variations of field current. This winding also reduces the amount of correction effected by winding W1 upon variation of motor supply voltage. A third carbon pile regulator winding W3 provides compensation for variations of load. Automatic regulation of alternator output voltage by controlling alternator field excitation may be provided. A vibrating contact regulator in place of the carbon pile regulator is referred to.

[Class 106 (i).] An apparatus for performing navigational calculations and for solving spherical triangles comprises five rotatable calibrated arcs so mounted that their axes of rotation intersect at a common point, shafts relatively movable in a common plane forming the rotational axes of two of the arcs. The arc 13, 14 is graduated with respect to latitude, arc 35 relates to azimuth, arc 36 to altitude, arc 60 to hourangles, and arc 65 to declination. The latitude arc 14 is carried by a ring 13 rotatable about an axis 17 and having a combined clamping and fine-adjustment device in the form of a tangent screw 24. A standard 28 is secured to the ring 13 and houses the bearings of the azimuth arc 35. To the disc 34 carrying the azimuth arc are attached two semicircular members 36 graduated on their outer faces to form the altitude arc. The altitude arc is provided with verniers 41 secured to an extension 40 of a yoke 37 pivoted at 38 to the disc 34. The hour-angle arc 60 is carried by a disc 59 secured to a shaft 44 rotated by a hand-wheel 45 through a friction clutch 47. To the shaft 44 is also secured a disc 52 to which can be locked an arm 55 by a screw 54. The arm 55 can be finely adjusted by a screw 57. The end of the shaft 44 carries a member 64 to which is attached the declination arc 65.
