Title: Improvements in lubricators
IPC: F16N7/34
Filed: 1928-07-05
Abstract: 323,518. Marks, E. C. R., (Decrow Automotive Specialties, Inc.). July 5, 1928À Lubricant conveyed by fluid. - Oil is carried into the induction manifold of an internal-combustion engine by air which is drawn through a chamber 41 arranged above an oil container 22, a wick 45 dipping into the oil and projecting vertically into the chamber being so arranged as completely to obstruct the chamber, whereby the air is compelled to pass transversely through the wick and be charged with oil. The chamber 41 and the air inlet and outlet passages 42, 43 are formed in the cover 20 which is secured tightly to the container, which is made of glass, by a clamping ring 25 of channel section which embraces flanges 21, 24 on the lever 20 and container respectively. The ring 25 is split or in sections adapted to be secured together, and is provided with projecting arms by which the device is secured to the engine. The outlet passage 43 is controlled by an adjustable valve 69 and communicates with a nipple 74, which is adapted to be connected to the induction manifold, through a glass tube 73. The passage of oil vapour through the tube 73 may be viewed through sight openings 75. A rotary sleeve valve 56 mounted in the cover 20 has ports 57, 58 adapted to register in one position of the valve with openings 54, 55 in the cover. In that position, the container may be recharged with oil by supply through the opening 54. The inner end of the sleeve 56 communicates with the passage 42, while a handle 63, a perforated screen 59 and a fibrous plug 60 are secured to the outer end, so that air drawn into the chamber 41 is filtered by its passage through the screen and plug. The container is vented to the outlet passage 43 through a passage 80. As shown, the wick 45 is of circular cross-section and has secured to its upper end a gauge disc 49 which rests on a shoulder 48 at the bottom of a chamber 46 arranged above the chamber 41, so as to support the wick. The latter may be withdrawn upwardly by removing a screwed plug 47. A passage 81 extends from the outlet side of the chamber 41 to the chamber 46, whereby the rise of the oil in the wick is facilitated. In a modified construction a flat wick is employed, the wick being held in a split metal holder, the flat sides of which are provided at their upper ends with oppositely-located openings through which the air passes.

Title: System for transmitting and receiving a plurality of pictures on a line sharing basis
IPC: H04N7/08
Filed: 1972-05-01
Abstract: 1389617 Television WESTINGHOUSE ELECTRIC CORP 1 May 1972 [17 May 1971] 20150/72 Heading H4F To enable the outputs A, B, Fig. 4 of a plurality (e.g. 2) of cameras C1, C2, Fig. 1, to be time division multiplexed into a single output signal E, every nth line of each camera signal starting at the rth line for the rth picture signal, e.g. odd lines for signal A and even lines for signal B, are selected by sequentially enabled respective gates G1, G2, to produce gated video signals C, D, which, after combination in adder A1, produce the desired composite signal E. At the receiver and display Fig. 2, every nth line from the sets of lines, commencing at the rth line in each frame, is selected such that these lines are all from the desired rth picture. The selected lines are delayed by (n-1) line time periods and combined with the undelayed line to give a composite video signal P having no line gaps, with an undelayed line followed by corresponding delayed line. With such a system if the frame comprises an odd number of lines there would be a change in the value of r from the end of one frame to the beginning of the next frame, e.g. if the lines selected for the first frame were 1, 3, 5 to 525, selecting alternate lines of the frame, then the first line selected in the next frame would be the second line and then the fourth line and so on such that a one line jump would be apparent in the consecutive displayed frames. To overcome this, a bi-stable circuit BT, causing the selection of the lines of the camera outputs for transmission, is reset, e.g. staggered by one line, at the end of each frame. Where one of the cameras is viewing a scene Fig. 7A having a diagonal transition between light and dark the use in the final display of only every other line causes the reproduction of the transistion as a jagged line. To overcome this various methods of combining video signals of adjacent lines and for averaging the combinations are given, e.g. Fig. 9 (not shown).

Filed: 1945-08-07
Abstract: 596,950. Friction and claw clutches. KESTERTON, H. M. Aug. 7, 1945, No. 20205. [Class 80(ii)] In a clutch having a female coned member b, Figs. 1 and 2, co-acting with a split resilient ring f on a male member d axially slidable relative to the female member for engagement, the ring is located by a wedge piece i, loosely supported on an axial flat h on the male member and entering between the adjacent ends of the ring, so that relative rotation between the ring and the male member caused by initial clutching expands the ring into further engagement. As shown, the ring f is flanged and supplementary clutching means are supplied consisting of rollers k, supported on polygonal surfaces j on the member d of corresponding taper to the female cone, and co-acting directly therewith through gaps in the flange. The rollers k are located by the ring, which passes through grooves therein and also through grooves g in the corners of the member d, sufficient play being allowed for independent action of both clutching means. Springs m urge the ring towards the clutching position. As shown applied to a friction synchronised positive clutch between two gear wheels p, r, Figs. 4 and 6, the female coned member b is slidably splined on the teeth of the wheel p and the flat h is on a complementary ring of teeth q on the wheel r. A solid section resilient ring e mounted over the teeth q is normally retained in the axial position shown by a spring clip s and is connected to the gear r through springs t, Fig. 4. On moving the member b to the right, the initial frictional engagement between it and the ring e rotates the latter slightly against the springs t relative to the gear r so that baulking pins u, Fig. 6, normally co-acting with bores v prevent the member b from positively engaging the teeth v until synchronisation is attained.
